Prospective investors should carefully consider the information set forth under the heading "Risk Factors." THE COMPANY Aastrom Biosciences, Inc. is developing proprietary process technologies and devices for a range of cell therapy applications, including stem cell therapies and gene therapy. The Company's lead product under development, the Aastrom Cell Production System (the "Aastrom CPS") consists of a clinical cell culture system with disposable cassettes and reagents for use in the rapidly growing stem cell therapy market. The Company believes that the Aastrom CPS method will be less costly, less invasive and less time consuming than currently available stem cell collection methods. The Aastrom CPS is designed as a platform product which implements the Company's pioneering stem cell replication technology and which the Company believes can be modified to produce a wide variety of cell types for emerging therapies. The Aastrom CPS is currently in a pre-pivotal clinical trial under an Investigational Device Exemption for autologous stem cell therapy. The Company has entered into a strategic collaboration for the development of the Aastrom CPS in stem cell therapy with Cobe BCT, Inc., a subsidiary of Gambro AB and a world leader in blood cell processing products. In ex vivo gene therapy, the Company is developing a proprietary directed motion gene transfer process (the "Aastrom Gene Loader") and the Aastrom CPS to enable high efficiency genetic modification and production of cells. Stem cell therapy is a rapidly growing form of cell therapy used to restore blood and immune system function to cancer patients following chemotherapy or radiation therapy. The Company estimates that over 35,000 stem cell therapy procedures were completed worldwide in 1995 and that the number of such procedures is growing at a compound annual rate of over 20%. Other novel cell therapies are under development by third parties, including stem cell therapy for the treatment of autoimmune diseases and for augmenting recipient acceptance of organ transplants. Current stem cell therapy methods, including bone marrow harvest and peripheral blood progenitor cell mobilization, are costly, invasive and time-consuming for both medical personnel and patients. Technologies which facilitate a more readily available source of cells may contribute to additional growth in cell therapy procedures. Umbilical cord blood ("UCB") is emerging as a new source of cells for stem cell therapy, offering additional market opportunity, although the more widespread use of UCB transplants has been restricted by cell quantity limitations. The Company believes that the Aastrom CPS will offer significant advantages over traditional cell collection methods. Compared with current stem cell collection methods, the Aastrom CPS is expected to involve one patient visit rather than approximately five to seven visits, less than two hours of procedure time rather than in excess of twenty hours of procedure time and approximately four to ten patient needle sticks rather than twenty-five or more patient needle sticks. The Aastrom CPS may permit higher and more frequent doses of chemotherapy to be administered to cancer patients by enabling the production of multiple doses of therapeutic stem cells from patient samples taken at the initial collection. Aastrom is currently conducting a pre-pivotal autologous stem cell therapy trial. The trial is designed to show that cells produced in the Aastrom CPS can by themselves safely enable recovery of bone marrow and cells of the blood and immune systems in accordance with trial endpoints in patients who have received ablative chemotherapy. Based on the outcome of this and other related trials, the Company intends to seek FDA approval to begin a multi-center pivotal trial for use of the Aastrom CPS in stem cell therapy. It is anticipated that the results of this pivotal trial will be used to support the Company's Pre-Market Approval ("PMA") submission to the FDA. In the near future, the Company plans to initiate a stem cell therapy clinical trial in France, the results of which are expected to be used for the CE Mark registration necessary to market the Aastrom CPS in Europe. The Company's business strategy is to: (i) establish a consumable-based business model; (ii) focus initially on the currently-reimbursed stem cell therapy market; (iii) leverage Aastrom's cell production technology across multiple cell therapy market opportunities; and (iv) market through collaborative relationships. Aastrom has entered into a strategic collaboration with Cobe BCT to support the development and marketing of the Aastrom CPS in the field of stem cell therapy. In 1993, the Company entered into a series of agreements in which Cobe BCT purchased $15,000,000 of the Company's equity securities and acquired the worldwide distribution rights to the Aastrom CPS for stem cell therapy. Under the terms of the collaboration, Aastrom retains manufacturing rights as well as the majority share of all revenue generated by Cobe BCT's sale of the Aastrom CPS. Aastrom also retains all marketing and distribution rights to the Aastrom CPS for other cell types and ex vivo gene therapy applications, including stem cells. The Company's patent portfolio includes patents relating to both stem and progenitor cell production, processes for the genetic modification of stem and other cell types, and cell culture devices for human cells. As of September 30, 1996, the Company had exclusive rights to five issued U.S. and three foreign patents, and a number of U.S. patent applications and certain corresponding foreign applications. 3 THE OFFERING Common Stock offered...... 3,250,000 shares Common Stock to be out- 13,235,734 shares(1) standing after this of- fering...................

See "Description of Capital Stock" and "Underwriting." This Prospectus contains forward-looking statements which involve risks and uncertainties. The Company's actual results may differ significantly from the results discussed in the forward-looking statements. Factors that might cause such differences include, but are not limited to, those discussed in "Risk Factors." 4 RISK FACTORS In addition to the other information in this Prospectus, prospective investors should consider the following risk factors in evaluating the Company and its business before purchasing any of the Common Stock offered hereby. UNCERTAINTIES RELATED TO PRODUCT DEVELOPMENT AND MARKETABILITY The Company has not completed the development or clinical trials of any of its cell culture technologies or product candidates and, accordingly, has not begun to market or generate revenue from their commercialization. Furthermore, the Company's technologies and product candidates are based on cell culture processes and methodologies which are not widely employed. Commercialization of the Company's lead product candidate, the Aastrom CPS, will require substantial additional research and development by the Company as well as substantial clinical trials. There can be no assurance that the Company will successfully complete development of the Aastrom CPS or its other product candidates, or successfully market its technologies or product candidates, which lack of success would have a material adverse effect on the Company's business, financial condition and results of operations. The Company or its collaborators may encounter problems and delays relating to research and development, regulatory approval and intellectual property rights of the Company's technologies and product candidates. There can be no assurance that the Company's research and development programs will be successful, that its cell culture technologies and product candidates will facilitate the ex vivo production of cells with the expected biological activities in humans, that its technologies and product candidates, if successfully developed, will prove to be safe and efficacious in clinical trials, that the necessary regulatory approvals for any of the Company's technologies or product candidates and the cells produced in such products will be obtained or, if obtained, will be as broad as sought, that patents will issue on the Company's patent applications or that the Company's intellectual property protections will be adequate. The Company's product development efforts are primarily directed toward obtaining regulatory approval to market the Aastrom CPS as an alternative to the bone marrow harvest and peripheral blood progenitor cell ("PBPC") stem cell collection methods. These stem cell collection methods have been widely practiced for a number of years, and there can be no assurance that any of the Company's technologies or product candidates will be accepted by the marketplace as readily as these or other competing processes and methodologies, or at all. The failure by the Company to achieve any of the foregoing would have a material adverse effect on the Company's business, financial condition and results of operations. UNCERTAINTIES RELATED TO CLINICAL TRIALS The approval of the United States Food and Drug Administration (the "FDA") will be required before any commercial sales of the Company's product candidates may commence in the United States, and approvals from foreign regulatory authorities will be required before international sales may commence. Prior to obtaining necessary regulatory approvals, the Company will be required to demonstrate the safety and efficacy of its processes and product candidates and the cells produced by such processes and in such products for application in the treatment of humans through extensive preclinical studies and clinical trials. To date, the Company has only tested the safety of cells produced in the cell culture chamber predecessor of the Aastrom CPS, and only in a limited numbers of patients. The Company is currently conducting a pre-pivotal clinical trial to demonstrate the safety and biological activity of patient-derived cells produced in the Company's cell culture chamber in a limited number of patients with breast cancer and, if the results from this pre-pivotal trial are successful, the Company intends to seek clearance from the FDA to commence its pivotal clinical trial. The results of preclinical studies and clinical trials of the Company's product candidates, however, may not necessarily be predictive of results that will be obtained from subsequent or more extensive clinical trials. Further, there can be no assurance that pre-pivotal or pivotal clinical trials of any of the Company's product candidates will demonstrate the safety and efficacy of such products, or of the cells produced in such products, to the extent necessary to obtain required regulatory approvals or market acceptance. The ability of the Company to complete its clinical trials in a timely manner is dependent upon many factors, including the rate of patient enrollment. Patient enrollment is a function of many factors, including the size of the patient population, the proximity of suitable patients to clinical sites and the eligibility criteria for the 5 study. The Company has experienced delays in patient accrual in its current pre-pivotal clinical trial. Further delays in patient accrual, in the Company's current pre-pivotal clinical trial or in future clinical trials, could result in increased costs associated with clinical trials or delays in receiving regulatory approvals and commercialization, if any. Furthermore, the progress of clinical investigations with the Aastrom CPS and the Company's other product candidates will be monitored by the FDA, which has the authority to cease clinical investigations, at any time, due to patient safety or other considerations. Any of the foregoing would have a material adverse effect on the Company's business, financial condition and results of operations. See "-- Uncertainty of Regulatory Approval" and "--Extensive Government Regulation." The Company's current pre-pivotal trial is designed to demonstrate specific biological safety and activity of cells produced in the Aastrom CPS, but is not designed to demonstrate long-term sustained engraftment of such cells. The patients enrolled in this pre-pivotal trial will have undergone extensive chemotherapy treatment prior to the infusion of cells produced in the Aastrom CPS. Such treatments will have substantially weakened these patients and may have irreparably damaged their hematopoietic systems. Due to these and other factors, there is risk that one or more of these patients may die or suffer severe complications during the course of the pre-pivotal trial. Further, there can be no assurance that patients receiving cells produced with the Company's technologies and product candidates will demonstrate long-term engraftment in a manner comparable to cells obtained from current stem cell therapy procedures, or at all. The failure to adequately demonstrate the safety or efficacy of the Company's technologies and product candidates, including long-term sustained engraftment, or the death of, or occurrence of severe complications in, one or more patients could substantially delay, or prevent, regulatory approval of such product candidates and have a material adverse effect on the Company's business, financial condition and results of operations. MANUFACTURING AND SUPPLY UNCERTAINTIES; DEPENDENCE ON THIRD PARTIES The Company does not operate and has no current intention to operate manufacturing facilities for the production of its product candidates. The Company currently arranges for the manufacturing of its product candidates and their components with third parties, and expects to continue to do so in the forseeable future. The Company has entered into collaborative product development agreements with SeaMED Corporation ("SeaMED") and Ethox Corporation ("Ethox") for the collaborative development and manufacture of certain components of the Aastrom CPS. The Company is also dependent upon Immunex Corporation ("Immunex"), Life Technologies, Inc., Biowhittaker and Anchor Advanced Products for the supply of certain cytokines, serum, media and injection molded materials, respectively, to be used in conjunction with, or as components of, the Aastrom CPS. With regard to cytokines that are not commercially available from other sources, Immunex is currently the Company's sole supplier and few alternative supply sources exist. Apart from SeaMED, Ethox and Immunex, the Company currently does not have contractual commitments from any of these manufacturers or suppliers. There can be no assurance that the Company's supply of such key cytokines, components and other materials will not become limited, be interrupted or become restricted to certain geographic regions. Furthermore, the Company currently only has the right to distribute cytokines obtained from Immunex in the United States and there can be no assurance that the Company will be able to obtain the worldwide right to distribute such cytokines or manufacture such cytokines by or for itself in the event that the Company's agreement with Immunex is terminated. There can also be no assurance that the Company will be able to obtain alternative components and materials from other manufacturers on terms or in quantities acceptable to the Company or that the Company will not require additional cytokines, components and other materials to manufacture or use its product candidates. In the event that any of the Company's key manufacturers or suppliers fail to perform their respective obligations or the Company's supply of such cytokines, components or other materials become limited or interrupted, the Company would not be able to market its product candidates on a timely and cost-competitive basis, if at all which would have a material adverse effect on the Company's business, financial condition and results of operations. Like SeaMED and Ethox, other suppliers would need to meet FDA manufacturing requirements and undergo rigorous facility and process validation tests required by federal and state regulatory authorities. Any significant delays in the completion and validation of such facilities could have a material adverse effect on the 6 ability of the Company to complete clinical trials and to market its products on a timely and profitable basis, which in turn would have a material adverse effect on the Company's business, financial condition and results of operations. There can also be no assurance that the Company will be able to continue its present arrangements with its suppliers, supplement existing relationships or establish new relationships or that the Company will be able to identify and obtain the ancillary materials that are necessary to develop its product candidates in the future. The Company's dependence upon third parties for the supply and manufacture of such items could adversely affect the Company's ability to develop and deliver commercially feasible products on a timely and competitive basis. HISTORY OF OPERATING LOSSES; ANTICIPATION OF FUTURE LOSSES The Company is a development stage company and there can be no assurance that its product applications for cell therapy will be successful. The Company has not yet completed the development and clinical trials of any of its product candidates and, accordingly, has not yet begun to generate revenues from the commercialization of any of its product candidates. Aastrom was incorporated in 1989 and has experienced substantial operating losses since inception. As of September 30, 1996, the Company has incurred net operating losses totaling approximately $30.3 million. Such losses have resulted principally from costs incurred in the research and development of the Company's cell culture technologies and the Aastrom CPS, general and administrative expenses, and the prosecution of patent applications. The Company expects to incur significant and increasing operating losses for at least the next several years, primarily owing to the expansion of its research and development programs, including preclinical studies and clinical trials. The amount of future losses and when, if ever, the Company achieves profitability are uncertain. The Company's ability to achieve profitability will depend, among other things, on successfully completing the development of its product candidates, obtaining regulatory approvals, establishing manufacturing, sales and marketing arrangements with third parties, and raising sufficient funds to finance its activities. No assurance can be given that the Company's product development efforts will be successful, that required regulatory approvals will be obtained, that any of the Company's product candidates will be manufactured at a competitive cost and will be of acceptable quality, or that the Company will be able to achieve profitability or that profitability, if achieved, can be sustained. LIMITED SALES AND MARKETING CAPABILITIES; DEPENDENCE ON COLLABORATIVE RELATIONSHIPS The Company has limited internal sales, marketing and distribution capabilities. If any of the Company's product candidates are successfully developed and the necessary regulatory approvals are obtained, the Company intends to market such products through collaborative relationships with companies that have established sales, marketing and distribution capabilities. The Company has established a strategic alliance with Cobe Laboratories, Inc. and Cobe BCT, Inc. (collectively, "Cobe") for the worldwide distribution of the Aastrom CPS for stem cell therapy and related uses. Cobe has the right to terminate its Distribution Agreement with the Company upon twelve month's notice upon a change of control of the Company, other than to Cobe, or at any time after December 31, 1997, if Cobe determines that commercialization of the Aastrom CPS for stem cell therapy on or prior to December 31, 1998 is unlikely. See "--Consequences of Cobe Relationship." The amount and timing of resources that Cobe commits to its strategic alliance activities with the Company are, to a significant extent, outside of the control of the Company. There can be no assurance that Cobe will pursue the marketing and distribution of the Company's products, continue to perform its obligations under its agreements with the Company or that the Company's strategic alliance with Cobe will result in the successful commercialization and distribution of the Company's technologies and product candidates. There can also be no assurance that Cobe will be successful in its efforts to market and distribute the Company's products for stem cell therapy. The suspension or termination of the Company's strategic alliance with Cobe or the failure of the strategic alliance to be successful would have a material adverse effect on the Company's business, financial condition and results of operations. Subject to the contractual requirements of the Cobe relationship, the Company will seek to enter into other agreements relating to the development and marketing of product candidates and in connection with such 7 agreements may rely upon corporate partners to conduct clinical trials, seek regulatory approvals for, manufacture and market its potential products. There can be no assurance that the Company will be able to establish collaborative relationships for the development or marketing of the Company's product candidates on acceptable terms, if at all. The inability of the Company to establish such collaborative relationships may require the Company to curtail its development or marketing activities with regard to its potential products which would have a material adverse effect on the Company's business, financial condition and results of operations. FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING To date, Aastrom has funded its operations primarily through the sale of equity securities and corporate collaborations. The Company anticipates that the net proceeds of this offering, together with the Company's available cash and expected interest income thereon, will be sufficient to finance its research and development and other working capital requirements for 18 months or less. This estimate is based on certain assumptions which could be negatively impacted by the matters discussed under this heading and elsewhere under the caption "Risk Factors." In order to grow and expand its business, and to introduce its product candidates into the marketplace, the Company will need, among other things, to raise additional funds. The Company's future capital requirements will depend upon many factors, including, but not limited to, continued scientific progress in its research and development programs, costs and timing of conducting clinical trials and seeking regulatory approvals and patent prosecutions, competing technological and market developments, possible changes in existing collaborative relationships, the ability of the Company to establish additional collaborative relationships, and effective commercialization activities and facilities expansions if and as required. Because of the Company's potential long-term funding requirements, it may attempt to access the public or private equity markets if and whenever conditions are favorable, even if it does not have an immediate need for additional capital at that time. There can be no assurance that any such additional funding will be available to the Company on reasonable terms, or at all. If adequate funds are not available, the Company may be required to delay or terminate research and development programs, curtail capital expenditures, and reduce business development and other operating activities. If the Company is not successful in finding, entering into and maintaining arrangements with collaborative partners, its development efforts could be delayed. Furthermore, there can be no assurance that the Company will be able to implement collaborative development agreements under acceptable terms. Any of the foregoing capital constraints would have a material adverse effect on the Company's business, financial condition and results of operations. See "Management's Discussion and Analysis of Financial Condition and Results of Operations--Liquidity and Capital Resources." UNCERTAINTY OF REGULATORY APPROVAL; EXTENSIVE GOVERNMENT REGULATION The Company's research and development activities, preclinical studies, clinical trials, and the anticipated manufacturing and marketing of its product candidates are subject to extensive regulation by the FDA and other regulatory authorities in the United States. These activities are also regulated in other countries where the Company intends to test and market its product candidates. The approval of the FDA will be required before any commercial sales of the Company's product candidates may commence in the United States. Additionally, the Company will be required to obtain approvals from foreign regulatory authorities before international sales may commence. The Company's products are potentially subject to regulation as medical devices under the Federal Food, Drug, and Cosmetic Act, or as biological products under the Public Health Service Act, or both. Different regulatory requirements may apply to the Company's products depending on how they are categorized by the FDA under these laws. To date, the FDA has indicated that it intends to regulate the Aastrom CPS for stem cell therapy as a Class III medical device through the Center for Biologics Evaluation and Research. However, there can be no assurance that the FDA will ultimately regulate the Aastrom CPS for stem cell therapy as a medical device or that regulatory approval for such product will be obtained in a timely fashion or at all. Further, it is unclear whether the FDA will separately regulate the cell therapies derived from the Aastrom CPS. The FDA is in the process of developing its requirements with respect to somatic cell therapy and gene cell therapy products, and recently proposed a new type of license for autologous cells manipulated ex vivo and 8 intended for structural repair or reconstruction; autologous cells are cells obtained from, and administered to, the same patient. This proposal may indicate that the FDA will impose a similar approval requirement on other types of autologous cellular therapies, such as autologous cells for stem cell therapy. Any such additional regulatory or approval requirement could significantly delay the introduction of the Company's product candidates to the market, and have a material adverse effect on the Company's business, financial condition and results of operations. Until the FDA issues definitive regulations covering the Company's product candidates, the regulatory requirements for approval of such product candidates will continue to be subject to significant uncertainty. Before marketing, the Aastrom CPS or other product candidates developed by the Company must undergo an extensive regulatory approval process. The regulatory process, which includes preclinical studies and clinical trials to establish safety and efficacy, takes many years and requires the expenditure of substantial resources. Data obtained from preclinical and clinical activities are susceptible to varying interpretations which could delay, limit or prevent FDA approval. In addition, delays or rejections may be encountered based upon changes in FDA policy for medical product approvals during the period of product development and FDA regulatory review of applications submitted by the Company for product approval. Similar delays may also be encountered in foreign countries. There can be no assurance that, even after the expenditures of substantial time and financial resources, regulatory approval will be obtained for any products developed by the Company. Moreover, if regulatory approval of a product is obtained, such approval may be subject to limitations on the indicated uses for which it may be marketed. Further, even if such regulatory approval is obtained, a marketed product, its manufacturer and its manufacturing facilities are subject to continual review and periodic inspections by the FDA, and later discovery of previously unknown problems with a product, manufacturer or facility may result in restrictions on such product or manufacturer, including a withdrawal of the product from the market. Failure to comply with the applicable regulatory requirements can, among other things, result in fines, suspensions of regulatory approvals, product recalls, operating restrictions and criminal prosecution. Further, additional government regulation may be established which could prevent or delay regulatory approval of the Company's products. See "Business--Government Regulation." CONSEQUENCES OF COBE RELATIONSHIP Following the completion of this offering, Cobe will be the largest single shareholder of the Company, beneficially owning approximately 19% of the outstanding Common Stock. In addition, Cobe has certain preemptive rights to maintain its relative percentage ownership and voting interest in the Company following this offering, and has the right, for a period of three years following this offering, to purchase from the Company an amount of Common Stock equal to 30% of the Company's fully diluted shares after the exercise of such option, at a purchase price equal to 120% of the public market trading price of the Company's Common Stock. If such option is exercised, Cobe would significantly increase its ownership interest in the Company and, as a consequence of such share ownership, obtain effective control of the Company. Such effective control would include the ability to influence the outcome of shareholder votes, including votes concerning the election of directors, the amendment of provisions of the Company's Restated Articles of Incorporation or Bylaws, and the approval of mergers and other significant transactions. Cobe also has been granted a "right of first negotiation" in the event that the Company determines to sell all, or any material portion, of its assets to another company or to merge with another company. Furthermore, the Company has agreed to use reasonable and good faith efforts to cause a nominee designated by Cobe to be elected to the Board of Directors for as long as Cobe owns at least 15% of the outstanding Common Stock. In addition, Edward C. Wood, Jr., the President of Cobe BCT, is a director of the Company. The existence of the foregoing rights or the exercise of such control by Cobe could have the effect of delaying, deterring or preventing certain takeovers or changes in control of the management of the Company, including transactions in which shareholders might otherwise receive a premium for their shares over then-current market prices. See "Description of Capital Stock--Rights of Cobe." UNCERTAINTY REGARDING PATENTS AND PROPRIETARY RIGHTS Aastrom's success depends in part on its ability, and the ability of its licensors, to obtain patent protection for its products and processes, preserve its trade secrets, defend and enforce its rights against infringement and 9 operate without infringing the proprietary rights of third parties, both in the United States and in other countries. The validity and breadth of claims in medical technology patents involve complex legal and factual questions and, therefore, may be highly uncertain. No assurance can be given that any patents based on pending patent applications or any future patent applications of the Company or its licensors will be issued, that the scope of any patent protection will exclude competitors or provide competitive advantages to the Company, that any of the patents that have been or may be issued to the Company or its licensors will be held valid if subsequently challenged or that others will not claim rights in or ownership of the patents and other proprietary rights held or licensed by the Company. Furthermore, there can be no assurance that others have not developed or will not develop similar products, duplicate any of the Company's products or design around any patents that have been or may be issued to the Company or its licensors. Since patent applications in the United States are maintained in secrecy until patents issue, the Company also cannot be certain that others did not first file applications for inventions covered by the Company's and its licensors' pending patent applications, nor can the Company be certain that it will not infringe any patents that may issue to others on such applications. The Company relies on certain licenses granted by the University of Michigan and Dr. Cremonese for the majority of its patent rights. If the Company breaches such agreements or otherwise fails to comply with such agreements, or if such agreements expire or are otherwise terminated, the Company may lose its rights under the patents held by the University of Michigan and Dr. Cremonese, which would have a material adverse effect on the Company's business, financial condition and results of operation. See "Business--Patents and Proprietary Rights--University of Michigan Research Agreement and License Agreement" and "Business--Patents and Proprietary Rights--License Agreement with J.G. Cremonese." The Company also relies on trade secrets and unpatentable know-how which it seeks to protect, in part, by confidentiality agreements with its employees, consultants, suppliers and licensees. There can be no assurance that these agreements will not be breached, that the Company would have adequate remedies for any breach, or that the Company's trade secrets or unpatentable know-how will not otherwise become known or be independently developed by competitors. The Company's success will also depend in part on its ability to develop commercially viable products without infringing the proprietary rights of others. The Company has not conducted freedom of use patent searches and no assurance can be given that patents do not exist or could not be filed which would have an adverse effect on the Company's ability to market its products or maintain its competitive position with respect to its products. If the Company's technology components, devices, designs, products, processes or other subject matter are claimed under other existing United States or foreign patents or are otherwise protected by third party proprietary rights, the Company may be subject to infringement actions. In such event, the Company may challenge the validity of such patents or other proprietary rights or be required to obtain licenses from such companies in order to develop, manufacture or market its products. There can be no assurance that the Company would be able to obtain such licenses or that such licenses, if available, could be obtained on commercially reasonable terms. Furthermore, the failure to either develop a commercially viable alternative or obtain such licenses could result in delays in marketing the Company's proposed products or the inability to proceed with the development, manufacture or sale of products requiring such licenses, which could have a material adverse effect on the Company's business, financial condition and results of operations. If the Company is required to defend itself against charges of patent infringement or to protect its own proprietary rights against third parties, substantial costs will be incurred regardless of whether the Company is successful. Such proceedings are typically protracted with no certainty of success. An adverse outcome could subject the Company to significant liabilities to third parties, and force the Company to curtail or cease its development and sale of its products and processes. See "Business--Patents and Proprietary Rights." NO ASSURANCE OF THIRD PARTY REIMBURSEMENT The Company's ability to successfully commercialize its product candidates will depend in part on the extent to which payment for the Company's products and related treatments will be available from government healthcare programs, such as Medicare and Medicaid, as well as private health insurers, health maintenance organizations and other third party payors. Government and other third-party payors are increasingly attempting to contain health care costs, in part by challenging the price of medical products and services. Reimbursement by third-party payors depend on a number of factors, including the payor's determination that use of the product 10 is safe and effective, not experimental or investigational, medically necessary, appropriate for the specific patient and cost-effective. Since reimbursement approval is required from each payor individually, seeking such approvals is a time-consuming and costly process which will require the Company to provide scientific and clinical support for the use of each of the Company's products to each payor separately. Significant uncertainty exists as to the payment status of newly approved medical products, and there can be no assurance that adequate third-party payments will be available to enable the Company to establish or maintain price levels sufficient to realize an appropriate return on its investment in product development. If adequate payment levels are not provided by government and third-party payors for use of the Company's products, the market acceptance of those products will be adversely affected. There can be no assurance that reimbursement in the United States or foreign countries will be available for any of the Company's product candidates, that any reimbursement granted will be maintained, or that limits on reimbursement available from third-party payors will not reduce the demand for, or negatively affect the price of, the Company's products. The unavailability or inadequacy of third-party reimbursement for the Company's product candidates would have a material adverse effect on the Company. Finally, the Company is unable to forecast what additional legislation or regulation relating to the healthcare industry or third-party coverage and reimbursement may be enacted in the future, or what effect such legislation or regulation would have on the Company's business. COMPETITION AND TECHNOLOGICAL CHANGE The Company is engaged in the development of medical products and processes which will face competition in a marketplace characterized by rapid technological change. Many of the Company's competitors have significantly greater resources than the Company, and have developed and may develop product candidates and processes that directly compete with the Company's products. Moreover, competitors that are able to achieve patent protection, obtain regulatory approvals and commence commercial sales of their products before the Company, and competitors that have already done so, may enjoy a significant competitive advantage. The Company's product development efforts are primarily directed toward obtaining regulatory approval to market the Aastrom CPS for stem cell therapy. That market is currently dominated by the bone marrow harvest and PBPC collection methods. The Company's clinical data, although early, is inconclusive as to whether or not cells expanded in the Aastrom CPS will enable hematopoietic recovery within the time frames currently achieved by the bone marrow harvest and PBPC collection methods. In addition, the bone marrow harvest and PBPC collection methods have been widely practiced for a number of years and, recently, the patient costs associated with these procedures have begun to decline. There can be no assurance that the Aastrom CPS method, if approved for marketing, will prove to be competitive with these established collection methods on the basis of hematopoietic recovery time, cost or otherwise. The Company also is aware of certain other products manufactured or under development by competitors that are used for the prevention or treatment of certain diseases and health conditions which the Company has targeted for product development. In particular, the Company is aware that competitors such as Amgen, Inc., CellPro, Incorporated, Systemix, Inc., Baxter Healthcare Corp. and Rhone- Poulenc Rorer Inc. ("RPR") are in advanced stages of development of technologies and products for use in stem cell therapy and other market applications currently being pursued by the Company. In addition, Cobe, a significant shareholder of the Company, is a market leader in the blood cell processing products industry and, accordingly, a potential competitor of the Company. There can be no assurance that developments by others will not render the Company's product candidates or technologies obsolete or noncompetitive, that the Company will be able to keep pace with new technological developments or that the Company's product candidates will be able to supplant established products and methodologies in the therapeutic areas that are targeted by the Company. The foregoing factors could have a material adverse effect on the Company's business, financial condition and results of operations. HAZARDOUS MATERIALS The Company's research and development activities involve the controlled use of hazardous materials, chemicals and various radioactive compounds. The Company is subject to federal, state and local laws and 11 regulations governing the use, manufacture, storage, handling and disposal of such materials and certain waste products. In the event of any contamination or injury from these materials, the Company could be held liable for any damages that result and any such liability could exceed the resources of the Company. Furthermore, the failure to comply with current or future regulations could result in the imposition of substantial fines against the Company, suspension of production, alteration of its manufacturing processes or cessation of operations. There can be no assurance that the Company will not be required to incur significant costs to comply with any such laws and regulations in the future, or that such laws or regulations will not have a material adverse effect on the Company's business, financial condition and results of operations. Any failure by the Company to control the use, disposal, removal or storage of, or to adequately restrict the discharge of, or assist in the cleanup of, hazardous chemicals or hazardous, infectious or toxic substances could subject the Company to significant liabilities, including joint and several liability under certain statutes. The imposition of such liabilities would have a material adverse effect on the Company's business, financial condition and results of operations. POTENTIAL PRODUCT LIABILITY; AVAILABILITY OF INSURANCE The Company is, and will continue to be, subject to the risk of product liability claims alleging that the use of its products has adverse effects on patients. This risk exists for product candidates tested in human clinical trials as well as products that are sold commercially, if any. Further, given the medical conditions for which the Aastrom CPS is expected to be utilized, any product liability claim could entail substantial compensatory and punitive damages. The assertion of product liability claims against the Company could result in a substantial cost to, and diversion of efforts by, the Company. There can be no assurance that the Company would prevail in any such litigation or that product liability claims, if made, would not result in a recall of the Company's products or a change in the indications for which they may be used. The Company maintains product liability insurance coverage in the aggregate of $5,000,000 for claims arising from the use of its product candidates in clinical trials. There can be no assurance that the Company will be able to maintain such insurance or obtain product liability insurance in the future to cover any of its product candidates which are commercialized or that such existing or any future insurance and the resources of the Company would be sufficient to satisfy any liability resulting from product liability claims. Consequently, a product liability claim or other claim with respect to uninsured or underinsured liabilities could have a material adverse effect on the Company's business, financial condition and results of operations. DEPENDENCE ON KEY PERSONNEL The success of the Company depends in large part upon the Company's ability to attract and retain highly qualified scientific and management personnel. The Company faces competition for such personnel from other companies, research and academic institutions and other entities. There can be no assurance that the Company will be successful in hiring or retaining key personnel. See "Business--Employees" and "Management." SHARES ELIGIBLE FOR FUTURE SALE Sales of substantial amounts of Common Stock in the public market following this offering could adversely affect the prevailing market price of the Common Stock and the Company's ability to raise capital in the future. Upon completion of this offering, the Company will have a total of 13,235,734 shares of Common Stock outstanding, of which the 3,250,000 shares offered hereby will be freely tradeable without restriction under the Securities Act of 1933, as amended (the "Securities Act") by persons other than "affiliates" of the Company, as defined under the Securities Act. The remaining 9,985,734 shares of Common Stock outstanding are "restricted securities" as the term is defined by Rule 144 promulgated under the Securities Act (the "Restricted Shares"). Of the 9,985,734 Restricted Shares, 6,996,920 shares may be sold under Rule 144, subject in some cases to certain volume restrictions and other conditions imposed thereby. An additional 152,056 shares will become eligible for sale 90 days after completion of the offering pursuant to Rule 144 and 701. The remaining 2,836,758 shares will be eligible for sale upon the expiration of their respective holding periods as set forth in Rule 144. The Securities and Exchange Commission has proposed certain amendments to Rule 144 that would reduce by one year the holding periods required for shares subject to Rule 144 to become eligible for resale in 12 the public market. This proposal, if adopted, would permit earlier resale of shares of Common Stock currently subject to holding periods under Rule 144. No assurance can be given concerning whether or when the proposal will be adopted by the Securities and Exchange Commission. Furthermore, 9,810,503 of the Restricted Shares are subject to lock-up agreements expiring 180 days following the date of this Prospectus. Such agreements provide that Cowen & Company may, in its sole discretion and at any time without notice, release all or a portion of the shares subject to these lock-up agreements. Upon the expiration of the lock-up agreements, 7,148,976 of the 9,985,734 Restricted Shares may be sold pursuant to Rule 144 or 701, subject in some cases to certain volume restrictions imposed thereby. Certain existing stockholders have rights to include shares of Common Stock owned by them in future registration by the Company for the sale of Common Stock or to request that the Company register their shares under the Securities Act. See "Description of Capital Stock--Registration Rights." Following the date of this Prospectus, the Company intends to register on one or more registration statements on Form S-8 approximately 1,837,160 shares of Common Stock issuable under its stock option and stock purchase plans. Of the 1,837,160 shares issuable under its stock option and stock purchase plans, 336,254 shares are subject to outstanding options as of September 30, 1996, 318,920 of which shares are subject to lock-up agreements. Shares covered by such registration statements will immediately be eligible for sale in the public market upon the filing of such registration statements. In addition, the Company has issued warrants to purchase 69,444 shares of Common Stock which become exercisable 90 days after the closing of this offering and, upon the effective date of this offering, will grant an immediately exercisable option to purchase 333,333 shares of Common Stock, which shares are subject to a lock-up agreement. See "Management--Benefit Plans," "Certain Transactions" and "Shares Eligible for Future Sale." CONTROL BY EXISTING MANAGEMENT AND SHAREHOLDERS Upon completion of this offering, the Company's directors, executive officers, and certain principal shareholders, including Cobe, affiliated with members of the Board of Directors and their affiliates will beneficially own approximately 39% of the Common Stock (approximately 38% if the Underwriters' over-allotment option is exercised in full). Accordingly, such shareholders, acting together, may have the ability to exert significant influence over the election of the Company's Board of Directors and other matters submitted to the Company's shareholders for approval. The voting power of these holders may discourage or prevent certain takeovers or changes in control of the management of the Company unless the terms are approved by such holders. See "Principal Shareholders." NO PRIOR PUBLIC MARKET; POSSIBLE STOCK PRICE VOLATILITY Prior to this offering there has been no public market for the Common Stock, and an active public market for the Common Stock may not develop or be sustained. The initial public offering price will be determined through negotiation between the Company and the Representatives of the Underwriters based on several factors that may not be indicative of future market prices. See "Underwriting" for a discussion of the factors considered in determining the initial public offering price. The trading price of the Common Stock and the price at which the Company may sell securities in the future could be subject to wide fluctuations in response to announcements of clinical results, research activities, technological innovations or new products by the Company or competitors, changes in government regulation, developments concerning proprietary rights, variations in the Company's operating results, announcements by the Company of regulatory developments, litigation, disputes concerning patents or proprietary rights or public concern regarding the safety, efficacy or other implications of the products or methodologies to be developed by the Company or its collaborators or enabled by the Company's technology, general market conditions, the liquidity of the Company or its ability to raise additional funds, and other factors or events. In addition, the stock market has experienced extreme fluctuations in price and volume. This volatility has significantly affected the market prices for securities of emerging biotechnology companies for reasons frequently unrelated to or disproportionate to the operating performance of the specific companies. These market fluctuations as well as general fluctuations in the stock markets may adversely affect the market price of the Common Stock. ANTI-TAKEOVER EFFECT OF CHARTER AND BY-LAW PROVISIONS AND MICHIGAN LAW The Company's Restated Articles of Incorporation authorize the Board of Directors to issue, without shareholder approval, 5,000,000 shares of Preferred Stock with voting, conversion, and other rights and 13 preferences that could materially and adversely affect the voting power or other rights of the holders of Common Stock. The issuance of Preferred Stock or of rights to purchase Preferred Stock could be used to discourage an unsolicited acquisition proposal. The Company's Bylaws contain procedural restrictions on director nominations by shareholders and the submission of other proposals for consideration at shareholder meetings. The possible issuance of Preferred Stock and the procedures required for director nominations and shareholder proposals could discourage a proxy contest, make more difficult the acquisition of a substantial block of Common Stock, or limit the price that investors might be willing to pay in the future for shares of Common Stock. In addition, certain provisions of Michigan law applicable to the Company could also delay or make more difficult a merger, tender offer, or proxy contest involving the Company. See "Description of Capital Stock." IMMEDIATE AND SUBSTANTIAL DILUTION; ABSENCE OF DIVIDENDS Purchasers of the Common Stock in this offering will experience immediate and substantial dilution in the net tangible book value of the Common Stock. Additional dilution is likely to occur upon the exercise of outstanding options granted by the Company. The Company has never paid cash dividends and does not anticipate paying any cash dividends in the foreseeable future. See "Dilution" and "Dividend Policy." THE COMPANY Aastrom was incorporated in Michigan in March 1989 under the name Ann Arbor Stromal, Inc. In 1991, the Company changed its name to Aastrom Biosciences, Inc. The Company's principal executive offices are located at 24 Frank Lloyd Wright Drive, P.O. Box 376, Ann Arbor, Michigan 48106 and its telephone number is (313) 930-5555. Aastrom(TM) and the Company's stylized logo are trademarks of the Company. Leukine and Neupogen are registered trademarks of Immunex Corporation and Amgen, Inc., respectively. USE OF PROCEEDS The net proceeds to the Company from the sale of the 3,250,000 shares of Common Stock offered hereby are estimated to be $26,302,500 ($30,382,875 if the Underwriters exercise their over-allotment option in full), at an assumed initial public offering price of $9.00 per share and after deducting underwriting discounts and commissions and estimated offering expenses payable by the Company. The net proceeds from this offering are expected to be used to fund product development of the Aastrom CPS, other research and development activities, including pre-pivotal and pivotal clinical trials of the Aastrom CPS, and for working capital and other general corporate purposes, including scheduled repayments of obligations under equipment leases. The Company has $339,000 of outstanding equipment lease commitments as of September 30, 1996 with final payments due between November 1996 and May 1999 and bear interest ranging from 9.7% to 12.1%. The Company anticipates that the net proceeds of this offering, together with the Company's available cash and expected interest income thereon, should be sufficient to finance the Company's research and development and other working capital requirements for approximately 18 months. This estimate is based on certain assumptions which could be negatively impacted by the matters discussed in "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations--Liquidity and Capital Resources." Pending such uses, the net proceeds will be invested in short- term, interest bearing investment grade securities. DIVIDEND POLICY The Company has never declared or paid any cash dividends on its Common Stock and does not anticipate paying such cash dividends in the foreseeable future. The Company currently anticipates that it will retain all future earnings, if any, for use in the development of its business. 14 CAPITALIZATION The following table sets forth the capitalization of the Company (i) as of September 30,1996, and (ii) on a pro forma as adjusted basis to reflect the conversion of all outstanding shares of Preferred Stock into Common Stock upon the closing of this offering and the receipt of the estimated net proceeds from the Company's sale of 3,250,000 shares of Common Stock pursuant to this offering. See "Use of Proceeds" and "Certain Transactions."

(2) Excludes options and warrants to purchase 1,132,361 shares of Common Stock at a weighted average exercise price of $6.50 per share, assuming the closing of this offering at a price of $9.00 per share. See "Management-- Stock Option and Employee Benefit Plans" and Notes 4 and 9 of Notes to Financial Statements. 15 DILUTION The Company's pro forma net tangible book value at September 30, 1996 was approximately $7,618,000 or $.76 per share. Pro forma net tangible book value per share represents the amount of the Company's shareholders' equity, less intangible assets, divided by 9,985,734, the number of shares of Common Stock outstanding as of September 30, 1996, after giving effect to the automatic conversion of all Preferred Stock into Common Stock upon the closing of this offering. After giving effect to the sale of 3,250,000 shares of Common Stock in this offering at an assumed initial public offering price of $9.00 per share and after deducting underwriting discounts and commissions and estimated offering expenses payable by the Company, the pro forma net tangible book value of the Company as of September 30, 1996 would have been $33,920,500, or $2.56 per share. This represents an immediate increase in pro forma net tangible book value of $1.80 per share to existing stockholders and an immediate dilution in pro forma net tangible book value of $6.44 per share to purchasers of Common Stock in this offering, as illustrated in the following table: Assumed initial public offering price per share............... $9.00 Pro forma net tangible book value per share as of September 30, 1996.................................................... $ .76 Increase per share attributable to new investors............. 1.80 ----- Pro forma net tangible book value per share after this offer- ing.......................................................... 2.56 ----- Dilution per share to new investors........................... $6.44 =====
Utilizing the foregoing assumptions, the following table summarizes the total consideration paid to the Company and the average price per share paid by the existing stockholders and by purchasers of shares of Common Stock in this offering:

The Company expects that its revenue sources for at least the next several years will continue to be limited to grant revenues and research funding, milestone payments and licensing fees from potential future corporate collaborators. The timing and amount of such future revenues, if any, will be subject to significant fluctuations, based in part on the success of the Company's research activities and the timing of the achievement of certain milestones. Substantially all of the Company's revenues from product sales, if any, will be subject to royalty payments ranging from 2% to 5%. Further, under the Company's Distribution Agreement with Cobe, Cobe will perform marketing and distribution activities and in exchange will receive from 38% to 42% of the Company's product sales in the area of stem cell therapy, subject to negotiated discounts and volume-based adjustments. Research and development expenses may fluctuate due to the timing of expenditures for the varying stages of the Company's research and clinical development programs. Research and development expenses will increase as product development programs and applications of the Company's products progress through research and development stages. Under the Company's License Agreement with Immunex, annual renewal fees of $1,000,000 are payable in each of the next four years. Under the Company's Distribution Agreement with Cobe, regulatory approval activities for the Company's products for stem cell therapies outside of the United States will be conducted, and paid for, by Cobe. As a result of these factors, the Company's results of operations have, and are expected to continue to, fluctuate significantly from year to year and from quarter to quarter and therefore may not be comparable to or indicative of the results of operations for other periods. Over the past several years, the Company's net loss has primarily increased, consistent with the growth in the Company's scope and size of operations. In the near term, the Company plans additional moderate growth in employee headcount necessary to address increasing requirements in the areas of product development, research, clinical and regulatory affairs and administration. Assuming capital is available to finance such growth, the Company's operating expenses will continue to increase as a result. At least until such time as the Company enters into arrangements providing research and development funding, the net loss will continue to increase as well. The Company has been unprofitable since its inception and does not anticipate having net income for several years. Through September 30, 1996, the Company had an accumulated deficit of $30,298,000. There can be no assurance that the Company will be able to achieve profitability on a sustained basis, if at all. This Prospectus contains, in addition to historical information, forward- looking statements that involve risks and uncertainties. The Company's actual results could differ materially from the results discussed in the forward- looking statements. Factors that could cause or contribute to such differences include those discussed under this caption, as well as those discussed under the caption "Risk Factors" and elsewhere in this Prospectus. RESULTS OF OPERATIONS THREE MONTHS ENDED SEPTEMBER 30, 1996 AND 1995 Total revenues were $224,000 for the three months ended September 30, 1996 compared to $211,000 for the same period in 1995. These revenues consist primarily of research and development revenue under the Company's research collaboration with RPR, which was terminated in September 1996. See "Certain Transactions." Total costs and expenses were $3,612,000 for the three months ended September 30, 1996 compared to $1,641,000 for the same period in 1995. The increase in costs and expenses in 1996 is primarily the result of an increase in research and development expenses to $3,160,000 in 1996 from $1,195,000 in 1995 and to a lesser extent by general and administrative expenses, which increased to $452,000 for the three months ended September 30, 1996 from $446,000 for the same period in 1995. 18 Interest income was $126,000 for the three months ended September 30, 1996 compared to $149,000 for the same period in 1995 and reflects a decrease in the levels of cash, cash equivalents and short-term investments in 1996. The Company's net loss increased to $3,273,000 for the three months ended September 30, 1996 from $1,299,000 for the same period in 1995, primarily as a result of increased costs and expenses in 1996. YEARS ENDED JUNE 30, 1996, 1995 AND 1994 Total revenues were $1,609,000 in 1996, $517,000 in 1995, and $872,000 in 1994. Grant revenues increased to $267,000 in 1996 from $121,000 in 1995, which had decreased from $823,000 in 1994, reflecting the timing of grant awards and related research activities and funding under the grants. Grant revenues accounted for 17%, 23% and 94% of total revenues for the years ended June 30, 1996, 1995 and 1994, respectively. Revenues from research and development agreements totaled $1,342,000 in 1996, $396,000 in 1995 and $49,000 in 1994, reflecting research funding received by the Company under its collaboration with RPR which commenced in September 1995. Revenues from RPR accounted for 83% and 48% of such revenue in 1996 and 1995, respectively. In September 1996, the Company's research collaboration with RPR terminated. Total costs and expenses were $12,142,000 in 1996, $6,447,000 in 1995, and $7,192,000 in 1994. The increase in 1996 costs and expenses, compared with 1995, is primarily the result of an increase in research and development expense to $10,075,000 in 1996 from $4,889,000 in 1995. The increase in research and development expense reflects an increase in research, clinical development and product development activities. The decrease in costs and expenses in 1995, compared with 1994, is primarily the result of a decrease in research and development expense to $4,889,000 in 1995 from $5,627,000 in 1994. General and administrative expenses were $2,067,000 in 1996, $1,558,000 in 1995 and $1,565,000 in 1994. The increase in general and administrative expenses in 1996 is the result of increasing finance, legal and other administrative and marketing expenses which are expected to continue to increase in support of the Company's increasing product development and research activities. The decrease in general and administrative expense in 1995 is reflective of generally lower spending in 1995 as compared to 1994. Interest income was $678,000 in 1996, $279,000 in 1995, and $245,000 in 1994. The increases in interest income in 1996 and 1995 are due primarily to corresponding increases in the levels of cash, cash equivalents and short-term investments for such periods. Interest expense was $62,000 in 1996, $66,000 in 1995, and $65,000 in 1994, reflecting varying amounts outstanding under capital leases during the periods. The Company's net loss was $9,917,000 in 1996, $5,717,000 in 1995, and $6,140,000 in 1994. The Company expects to report substantial net losses for at least the next several years. The Company has not generated any net income to date and therefore has not paid any federal income taxes since inception. At June 30, 1996, the Company had deferred tax assets totaling $9,650,000 consisting primarily of net operating loss and research tax credits that begin to expire from 2004 through 2011, if not utilized. A full valuation allowance for deferred tax assets has been provided. Utilization of federal income tax carryforwards is subject to certain limitations under Section 382 of the Internal Revenue Code of 1986, as amended. The completion of this offering is likely to limit the Company's ability to utilize federal income tax carryforwards under Section 382. The annual limitation could result in expiration of net operating losses and research and development credits before their complete utilization. LIQUIDITY AND CAPITAL RESOURCES The Company has financed its operations since inception primarily through private placements of Preferred Stock and other equity investments, which from inception, have totaled approximately $37,916,000, and to a lesser degree, through grant funding, payments received under research agreements and collaborations, interest 19 earned on cash, cash equivalents, and short-term investments, and funding under equipment leasing agreements. These financing sources have historically allowed the Company to maintain adequate levels of cash and other liquid investments. The Company's combined cash, cash equivalents and short-term investments totaled $10,967,000 at June 30, 1996, a decrease of $101,000 from June 30, 1995. The primary uses of cash, cash equivalents and short-term investments during the year ended June 30, 1996 included $8,967,000 to finance the Company's operations and working capital requirements, $445,000 in capital equipment additions and $270,000 in scheduled debt payments. During the year ended June 30, 1996, the Company received $3,500,000 in equity payments from RPR and $5,965,000 in net proceeds from the sale of Series E Convertible Preferred Stock. The Company plans to continue its policy of investing excess funds in short-term, investment-grade, interest-bearing instruments. The Company's combined cash, cash equivalents and short-term investments totaled $7,108,000 as of September 30, 1996 compared to $10,967,000 at June 30, 1996. The decrease was primarily attributable to the use of $3,614,000 to fund operations and working capital requirements during the period and to a lesser degree by $173,000 in capital equipment purchases and $73,000 in scheduled debt payments. In October 1996, the Company executed a financing commitment to provide the Company with up to $5,000,000 in additional equity funding from Cobe and $5,000,000 under a convertible loan agreement with another current investor. In connection with the convertible loan agreement, the Company has issued warrants to purchase 69,444 shares of Common Stock for securing the commitment. The warrants expire on October 15, 2000 if not exercised, and may be exercised, in whole or in part, at a price equal to the lesser of (a) $9.00 per share, which price increases by $3.00 per share on each anniversary of the closing of the offering being made hereby; or (b) 85% of the fair market value of the Company's Common Stock at the time of exercise. As of the date of this Prospectus, the Company has not obtained any financing under these commitments. These funding commitments expire upon the closing of this offering. The Company's future cash requirements will depend on many factors, including continued scientific progress in its research and development programs, the scope and results of clinical trials, the time and costs involved in obtaining regulatory approvals, the costs involved in filing, prosecuting and enforcing patents, competing technological and market developments and the cost of product commercialization. The Company does not expect to generate a positive cash flow from operations for several years, if at all, due to the expected increase in spending for research and development programs and the expected cost of commercializing its product candidates. The Company may seek additional funding through research and development agreements with suitable corporate collaborators and through public or private financing transactions. The Company anticipates that the net proceeds of this offering, together with the Company's available cash and expected interest income thereon, will be sufficient to finance its research and development and other working capital requirements for 18 months or less. This estimate is based on certain assumptions which could be negatively impacted by the matters discussed under this heading and elsewhere under the caption "Risk Factors." The Company expects that its primary sources of capital for the foreseeable future will be through collaborative arrangements and through the public or private sale of its equity securities. There can be no assurance that such collaboration arrangements, or any public or private financing transaction, will be available on acceptable terms, if at all, or can be sustained on a long-term basis. If adequate funds are not available, the Company may be required to delay, reduce the scope of, or eliminate one or more of its research and development programs, which may have a material adverse effect on the Company's business. See "Risk Factors--Future Capital Needs; Uncertainty of Additional Funding" and Notes to Financial Statements. RECENT PRONOUNCEMENTS During October 1995, the Financial Accounting Standards Board issued Statement No. 123, "Accounting for Stock-Based Compensation," which establishes a fair value based method of accounting for stock-based compensation and incentive plans and requires additional disclosures for those companies that elect not to adopt 20 the new method of accounting. Adoption of the new accounting pronouncement is required for the Company's fiscal year beginning July 1, 1996 and the Company intends to provide the additional disclosures required by the pronouncement in its financial statements for the year ended June 30, 1997. During March 1995, the Financial Accounting Standards Board issued Statement No. 121, ("SFAS 121") "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," which requires the Company to review for impairment of long-lived assets, certain identifiable intangibles, and goodwill related to those assets whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. In certain situations, an impairment loss would be recognized. SFAS 121 will become effective for the Company's fiscal year beginning July 1, 1996. Management has studied the effect of implementing SFAS 121 and, based upon its initial evaluation, does not expect it to have a significant impact on the Company's financial condition or results of operations. 21 BUSINESS OVERVIEW Aastrom is developing proprietary process technologies and devices for a range of cell therapy applications, including stem cell therapies and gene therapy. The Company's lead product under development, the Aastrom Cell Production System (the "Aastrom CPS"), consists of a clinical cell culture system with disposable cassettes and reagents for use in the rapidly growing stem cell therapy market. The Company believes that the Aastrom CPS method will be less costly, less invasive and less time consuming than currently available stem cell collection methods. The Aastrom CPS is designed as a platform product which implements the Company's pioneering stem cell replication technology and which the Company believes can be modified to produce a wide variety of cell types for emerging therapies. The Aastrom CPS is currently in a pre-pivotal clinical trial under an IDE for autologous stem cell therapy. The Company has entered into a strategic collaboration for the development of the Aastrom CPS in stem cell therapy with Cobe BCT, Inc., a subsidiary of Gambro AB and a world leader in blood cell processing products. Additionally, Aastrom is developing products and processes for the delivery of ex vivo gene therapy that are designed to address the production of gene- modified cells. CELL THERAPY Cell therapy is the use of human cells to treat a medical disorder. The most common types of cell therapy, blood and platelet transfusions, have been widely used for many decades. More recently, bone marrow-derived cells have been used to restore the bone marrow and the blood and immune system cells which are damaged by chemotherapy and radiation therapy during the treatment of many cancers. Transplantation of these cells is known as stem cell therapy. Other cell therapies have recently been used for generating skin and cartilage tissue and additional cell therapies are being developed by various companies and researchers to restore immune system cells as well as bone, kidney, liver, vascular and neuronal tissues. Cell therapies require the collection of cells, either from the patient or a suitably matched donor. These cells are typically processed and stored for administration to the patient. Although cell therapy is being developed for use in an increasing number of diseases, widespread application of new cell therapies remains limited by the difficulties and expense associated with current cell collection and processing procedures. The problems of current cell collection techniques are exemplified in the area of stem cell therapy where the patient or donor undergoes invasive, time-consuming and costly procedures to collect the large volume of cells currently required for effective treatment. The Company believes an alternative to collecting the required therapeutic dose of cells is to grow these cells ex vivo from a small starting volume. However, ex vivo cell expansion, when biologically possible, has typically required costly techniques, facilities and operations to comply with FDA good manufacturing practices ("GMP"), which are not generally available in hospitals. As a result, cells needed for such therapies often require specialized cell production facilities which use labor-intensive, manual cell culture techniques. There are numerous forms of cell therapy at an early stage of development. One such example is ex vivo gene therapy, in which genes are introduced into target cells in order to selectively correct or modulate disease conditions, or to modify cells for production of a therapeutic protein. The Company believes that the successful practice of ex vivo gene therapy will require the development of processes and products for the reliable, high-efficiency transfer of genes into cells and a means to produce the necessary dose of the genetically modified cells under GMP conditions. STEM CELL THERAPY Stem cell therapy is used to treat cancer patients who undergo chemotherapy or radiation therapy at dose levels that are toxic to the hematopoietic system, which is comprised of the bone marrow and cells of the blood and immune systems. The objective of stem cell therapy is to restore the hematopoietic system via the infusion and subsequent engraftment of healthy cells to replace bone marrow and result in the rapid recovery of neutrophils and platelets that have been destroyed by chemotherapy and radiation therapy. Stem cell therapy 22 reduces the risk of life-threatening infections and bleeding episodes following cancer treatments. In order to treat many cancers, high intensity chemotherapy or radiation is often required, which may severely destroy ("myeloablation") or partially destroy ("myelosuppression") the patient's hematopoietic system. Cells required for effective stem cell therapy include stem cells, to replenish depleted bone marrow and provide a long-term ongoing source of the multilineage progenitor cells of the blood and immune systems, and early and late stage hematopoietic progenitor cells, to provide for rapid neutrophil and platelet recoveries. Stromal accessory cells are believed to further augment the growth of bone marrow. In the adult, all of these cell types originate in the bone marrow. These cells are currently collected from the donor or patient directly through multiple syringe aspirations under anesthesia, known as bone marrow collection, or through blood apheresis following treatment with drugs which cause cells to be released or mobilized from the bone marrow into the blood. This latter technique is known as a peripheral blood progenitor cell ("PBPC") collection. See "--Current Stem Cell Collection Methods." Recently, it has been demonstrated that the blood cells found in the umbilical cord of newborn infants include cells effective for stem cell therapy. This source of cells is being explored by physicians as a major new direction in stem cell therapy, but is currently limited by difficulties in obtaining sufficient quantities of these cells. Once collected, the stem cell mixture is infused intravenously and the stem and stromal accessory cells migrate into the bone cavity where they engraft to form a new marrow. The hematopoietic progenitor cell components of the cell mixture provide early restoration of circulating white blood cells and platelets. The replenished bone marrow will normally provide long-term hematopoietic function, but complete restoration of bone marrow may take years following myeloablative cancer therapy. When the patient's hematopoietic system is malignant, such as in the case of leukemia, cells from a suitable donor are generally required in order to avoid reintroducing the disease during cell infusion. Such donor derived transplants are termed "allogeneic" transplants. Procedures using cells derived from the patient are termed "autologous" transplants. STEM CELL THERAPY MARKET OPPORTUNITY The benefits of stem cell therapy in the treatment of cancer patients have been well established over the past two decades. Stem cell therapy, in the form of bone marrow transplantation, was originally used in patients who had received treatment for blood and bone marrow cancers such as leukemia, and genetic diseases of the blood. However, because stem cell therapy has been shown to promote the rapid recovery of hematopoietic function, it is now being increasingly used to enable patients with other forms of cancer to receive high dose or multicycle chemotherapy and radiation treatments. These high intensity therapies have a greater probability of eradicating dose sensitive cancers but, because of their hematopoietic toxicity, cannot generally be given without stem cell therapy. As a result, some patients are treated with lower and less effective doses, and fewer cycles, of therapy than might otherwise be used. The Company estimates that over 35,000 stem cell therapy procedures were completed worldwide in 1995, and that the number of such procedures is growing at a compound annual rate of over 20%. This growth has been driven by encouraging clinical results in the treatment of dose-sensitive solid tumors, such as breast and ovarian cancers. The Company expects that stem cell therapy procedures will continue to grow due to increased incidence and prevalence of cancer, continued clinical demand for myelotoxic cancer treatment, and the increased cost effectiveness of stem cell therapy treatments. Stem cell therapy may also enhance the effectiveness of blood cell growth factors. The timing and extent of additional cycles of chemotherapy is often limited by the recovery of a patient's white blood cells and platelets because a delayed recovery of these cells can leave the patient susceptible to life- threatening infection and bleeding episodes, and this limitation may allow for the regrowth of residual tumor cells. Many cancer patients are routinely treated with growth factors including G-CSF, such as Neupogen and GM-CSF, such as Leukine, which enhance the development of mature circulating white blood cells and platelets from the early progenitor bone-marrow derived cells, thereby decreasing the time between cycles of therapy and the probability of infection. However, during high dose or multi-cycle therapy, the stem and progenitor cells on which these growth 23 factors act are often depleted. Without these cells, growth factors have a limited or negligible effect. Stem cell therapy generally enhances the effectiveness of growth factors by introducing target stem and progenitor cells for growth factors to act upon such that patients generally exhibit a more rapid and consistent hematopoietic recovery. CURRENT STEM CELL COLLECTION METHODS Currently, the bone marrow-derived cells required for stem cell therapy are collected primarily either through the bone marrow harvest method or the PBPC collection method. Bone Marrow Harvest A traditional bone marrow harvest is a costly and invasive surgical procedure in which a physician removes approximately one liter of bone marrow from a patient or donor. This volume of bone marrow is removed using needles inserted into the cavity of the hip bone. The bone marrow harvest procedure typically requires between two to four hours of operating room time, with the physician often making more than 100 separate puncture sites in the hip bone to collect the necessary amount of bone marrow. Due to the length of the procedure and the trauma to the patient, general surgical anesthesia is administered and the patient is typically hospitalized for a day. Frequently, the patient suffers pain from the procedure for several days after being discharged from the hospital. Furthermore, complications resulting from the general anesthesia or invasive nature of the procedure occur in a small percentage of patients. Bone marrow harvest provides a reliable source of stem and stromal accessory cells and has been the preferred source of cells in allogeneic transplants. PBPC Mobilization and Collection PBPC mobilization is a newer technique in which bone marrow-derived cells are harvested from a patient's or donor's circulating blood, rather than from bone marrow. In a PBPC mobilization procedure, the patient receives multiple injections of growth factors or cytotoxic drugs, or both, over the course of a week or more, which cause stem and progenitor cells resident in the bone marrow to mobilize into the circulating blood. The mobilized cells are then collected by connecting the patient to a blood apheresis device, which draws and returns large volumes of the patient's or donor's blood in order to selectively remove the therapeutic volume of stem and progenitor cells. Each collection procedure typically lasts for two to six hours and is typically repeated on two to eight consecutive days. Specialized laboratory testing over the period of mobilization and cell harvesting is necessary to determine that a sufficient quantity of desired cells has been collected, adding to the cost of the procedure. The PBPC process has become the predominant procedure in autologous stem cell therapy. Procedure Considerations Although stem cell therapy is being utilized to treat more patients for a broader range of diseases, its availability continues to be limited by the high costs of procuring cells, the invasive nature of traditional cell procurement techniques, and by the technical difficulties related to those collection procedures. The Company estimates that current costs for bone marrow harvest and processing are approximately $10,000 to $15,000 per procedure, with considerable variability between institutions. The Company estimates that current costs for PBPC collection, including mobilization with growth factors, are approximately $12,000 to $20,000 for a two to three cycle procedure, with considerable variability between institutions depending on the total volume, time and number of aphereses required. Overall costs of stem cell therapy include the costs of the cell collection procedure, and the costs associated with supporting the patient during post- transplant recovery. Post-transplant costs include hospitalization time, antibiotic support, management of adverse reactions to the large volume cell infusions, and infusions of platelets and red blood cells. Any new stem cell therapy process will generally need to provide similar recovery endpoints to be competitive with the current procedures. In this regard, PBPC procedures have gained popularity compared with bone marrow harvests because the number of platelet transfusions is reduced for some patients. 24 Recently, products to implement a cell isolation method known as CD34 selection have been developed by other companies in conjunction with bone marrow harvest and PBPC collections. CD34 selection is a process designed to isolate specific types of cells in order to decrease storage and infusion problems associated with the large volume of fluids collected in bone marrow or multiple apheresis procedures. CD34 selection is used after the initial collection of stem and progenitor cells and, therefore, does not address the difficulties or costs associated with the basic cell collection procedures. To date, the CD34 selection procedure has demonstrated limited therapeutic benefit to the patient, but substantially increases the costs of the procedure. A future objective of CD34 selection is to assist in depleting tumor cells from the transplant cells collected, thereby expanding the availability of stem cell therapy to new patient populations. UMBILICAL CORD BLOOD Umbilical cord blood ("UCB"), which is collected directly from the umbilical cord after delivery, without pain or risk to the infant or the mother, is emerging as a new source of cells for stem cell therapy. UCB has been reported to have stem cell concentrations that are much higher than that typically obtained from traditional bone marrow and PBPC collection methods. After collection, UCB is typically frozen for later use in a stem cell therapy procedure. Storage of UCB samples involves small volumes of cells, compared to typical bone marrow or PBPC storage. Accordingly, the costs of collection and storage of UCB cells are comparatively low. This source of cells is also "tumor-free," such that UCB would be preferred for many current stem cell therapy procedures in metastatic cancer patients. Before UCB can become a major supply source for stem cell therapy, a coordinated UCB banking system must emerge. In this regard, several organized UCB banking institutions have been established to date, and the group is growing in both number and size. One current disadvantage of UCB is the relatively low number of available cells. Unlike bone marrow or PBPC harvest, where the collection of more cells to meet a particular treatment is typically achievable, the number of cells available from a UCB donor is limited. This problem is exacerbated by the required cryopreservation of the cells, which causes a significant cell loss. The resultant low cell number is believed to be responsible for the longer hematopoietic recovery times observed with UCB transplants, as compared with bone marrow or PBPC transplants. Further, because of the low cell number, UCB transplants are typically restricted to small patients. Therefore, increasing the number of therapeutic cells from a UCB sample would facilitate the more widespread use of UCB transplants. Aastrom believes that providing the transplant site with the capability to carry out the UCB cell expansion will be a major factor in the increased use of UCB for stem cell therapy and a significant business opportunity. AASTROM TECHNOLOGY Aastrom is developing proprietary process technologies that are pioneering the ex vivo production of human stem and progenitor cells. The Company has also developed a proprietary cell culture device that mimics the biological and physical environment necessary for the growth of certain human cells and tissues, including bone marrow. The Company's initial product candidate, the Aastrom CPS, utilizes the Company's process technology and is designed to enable the ex vivo production of human stem and progenitor cells as an alternative to the bone marrow harvest and PBPC mobilization methods and as an enhancement to the UCB collection method. The Company believes that the Aastrom CPS may be used for other cell production processes which are being developed by third parties and, in combination with the Company's proprietary gene transfer process, may have application in the developing field of ex vivo gene therapy. CORE TECHNOLOGY Stem Cell Growth Process Aastrom has developed proprietary process technologies for ex vivo production of therapeutic stem and progenitor cells as well as other key cells found in human bone marrow. The Company's proprietary process entails the placement of a stem cell mixture in a culture environment that mimics the biology and physiology of 25 natural bone marrow. This process enables the stem and early and late-stage progenitor cells needed for an effective stem cell therapy procedure to be concurrently expanded. Growth factors can be added to stimulate specific cell lineages to grow or to increase cell growth to meet a particular therapeutic objective. The stem cell growth process can best be completed with little or no additional stem cell selection or purification procedures. This stem cell replication process can also enable or augment the genetic modification of cells by providing the cell division step needed for new genes to integrate into the stem cell DNA. Currently available cell culture methods tend to result in a loss of stem cells, either through death or through differentiation into mature cells. The Company has exclusive license to two U.S. patents and additional applications that cover these processes. See "-- Additional Stem Cell and Other Cell Therapies." Aastrom Cell Culture Chamber Aastrom has developed a proprietary cell culture chamber to implement the Company's process technology. The culture chamber produces cells on a clinical scale, and allow for simple, sterile recovery of the cells for therapeutic use. The Company believes that the Aastrom cell culture chamber may also be used for growing other human therapeutic cells, such as T-Cells used for lymphocyte therapies, chondrocytes for cartilage replacement, and mesenchymal tissues for bone and cartilage replacement. The Company holds exclusive licenses to two U.S. patents and additional applications for its cell culture chamber device technology. See "--Additional Stem Cell and Other Cell Therapies." Efficient Gene Transfer Aastrom has developed proprietary processes and device technology that enables increased efficiency of vector-mediated gene transfer into cells as compared to conventional procedures. This directed-motion gene transfer or gene loading technology is intended to have applications for most cell and tissue types and most vector technologies. The Company intends to develop products based upon its gene loading technology that it believes will facilitate the advancement of numerous gene therapy protocols into the clinic and ultimately the market. The Company has received a U.S. Patent and has additional applications for this technology. See "Aastrom Product Candidates For Ex Vivo Gene Therapy." THE AASTROM CPS The Aastrom CPS is the Company's lead product under development for multiple cell therapy applications, including stem cell therapy. The Aastrom CPS is a proprietary system that the Company believes will enable the large scale ex vivo production of a variety of therapeutic cells at health care facilities, independent laboratories, transplant centers and blood banks, and has been designed to implement Aastrom's stem cell growth process as well as processes for the production of other cell types. The Aastrom CPS is comprised of several components, including single-use disposable cassettes and reagents and microprocessor-controlled instruments, which are at various stages of development. The Cell Cassette is a single-use disposable cartridge which contains the Aastrom cell culture chamber and the related media supply waste reservoirs and harvest bag. The microprocessor- controlled instruments include the Incubator which controls the culture conditions for the operation of the Cell Cassette, and the Processor which automates the priming and harvesting of the cells from the cell cassette. The System Manager is a user interface computer that is being developed to simultaneously track and monitor the cell production process in over thirty CPS Incubators and record relevant process variables and operator actions. Prototype components of the Aastrom CPS are currently being used in a clinical trial and ongoing development activities are directed at completing other production level components of the Aastrom CPS. The Aastrom CPS is designed to be operated with minimal operator activity by a medical or laboratory technician and can implement clinical scale cell production at the patient care site. The end product of the Aastrom process is a sterile bag of cells. The control and documentation features of the Aastrom CPS have been designed to meet GMP requirements for the therapeutic production of cells. 26 AASTROM CPS FOR STEM CELL THERAPY The Company's initial application for the Aastrom CPS is expected to be in the growing field of stem cell therapy, where the Company believes that the Aastrom CPS may address many of the limitations of existing procedures. The Aastrom CPS is based on a comparatively simple process in which a small volume of bone marrow cells are collected from the patient or donor using a needle aspiration procedure under a local anesthetic or sedative. This cell mixture is quantified, and an appropriate volume of cells is then inoculated into one or more cell cassettes with the necessary growth media. Therapeutic growth- factor-stimulated cells are produced using the Aastrom CPS in approximately 12 to 13 days, with no further patient involvement. Depending upon the cell quantity necessary for a therapeutic application, single or multiple cell cassettes may be required, with a different volume requirement of starting cells. The Aastrom CPS has been designed to minimize operator involvement during the cell production process, and the steps required before and after the Aastrom CPS are standard laboratory procedures. Advantages of Aastrom CPS The Company believes that the Aastrom CPS, if approved for commercial sale by the FDA and foreign regulatory agencies, will provide improvements and efficiencies over traditional cell collection processes. The following table illustrates some potential advantages of the Aastrom CPS compared to approximated patient visits, procedure time and needle sticks in connection with currently established cell collection techniques:
CELL SOURCE VISITS(1) PROCEDURE TIME (HOURS) NEEDLE STICKS(2) ----------- --------- ---------------------- ---------------- Bone Marrow Harvest(3)..... 6 22 100+ PBPC Mobilization and Col- lection(4)................ 5-7 23-27 20-30 Aastrom CPS(5)............. 1 1-2 4-10
-------- (1) Includes all outpatient, inpatient, and home care episodes. (2) Includes bone marrow aspirates, blood samples, catheter placements, and subcutaneous injections. (3) Includes operating room procedure and all preparatory screening and testing. (4) Based on two to three 4-hour rounds of PBPC mobilization and collection after sequential G-CSF blood mobilization injections. (5) Based on data accumulated during the Company's clinical trials. Reduced Cost. The Company believes the Aastrom CPS has the potential to replace more costly, labor intensive and invasive cell collection procedures currently employed for stem cell therapy and to reduce physician, staff and patient time requirements. Reduced Patient and Physician Burden. Cell production with the Aastrom CPS is expected to require the collection of a small volume of starting material compared to current collection procedures, eliminating the requirement for general surgical anesthesia, multiple drug injections and blood apheresis. Patient benefits include fewer needle sticks than with current cell collection methods and a reduction in overall patient procedure time. Additionally, Aastrom's process for cell expansion is expected to minimize the time requirement for physicians compared with bone marrow harvest. Enhanced Multicycle High-Dose Chemotherapy. The long restoration period for the hematopoietic system following myeloablative therapy effectively limits patients to one opportunity for cell collection prior to cancer therapy. The Aastrom CPS may enhance the practice of multi-cycle, high-dose chemotherapy by providing the ability to produce a therapeutic dose of cells from a small starting volume. The initial cell collection can be divided into multiple samples and stored frozen until expansion at a later time is required. Reduced Quantity of Lymphocytes. The Company believes its approach to stem cell therapy may provide an additional benefit over current methods by depleting potentially harmful cells such as T-cells and B-cells. These cells are believed to be primarily responsible for graft-versus-host disease, a common manifestation of allogeneic transplants in which the grafted donor's cells attack the host's tissues and organs. 27 Tumor Cell Purging. Cancer patients with tumor metastases, in which the cancer has spread to the blood and bone marrow, have not traditionally been candidates for autologous stem cell transplants because transplant may reintroduce cancer cells into the patient. Additionally patients may have undetected tumor cells in their marrow or PBPC transplant, which can reestablish the cancer in the patient following transplant. The Aastrom CPS process may offer benefits for these groups of patients. The Company and other investigators have shown that some primary human tumor cells die or do not grow during hematopoietic cell culture. Further, the smaller volume of starting cells used for the Aastrom CPS compared with BMT or PBPC transplants shall provide approximately 10 to 70 fold less tumor cells in a transplant. This combination of passive depletion during culture with the lower starting volume of tumor cells may result in a tumor-free or tumor-reduced cell product for transplant. The benefit of such tumor depletion, if any, will vary depending upon the type of cancer and state of disease. CLINICAL DEVELOPMENT The Company's clinical development plan is initially to obtain regulatory approval in the United States to market the Aastrom CPS for autologous stem cell therapy and in Europe for more general cell therapy applications. The Company also intends to pursue approval of the Aastrom CPS for additional clinical indications. The Company believes that the Aastrom CPS for stem cell therapy will be regulated as a medical device and that the Company will be required to submit a PMA application to, and obtain approval from, the FDA to allow it to market this product in the United States. In order to obtain PMA approval, the Company will be required to complete clinical trials under an IDE. See "-- Government Regulation--Devices." In a dose-ranging study conducted by the University of Michigan (the "University") in 1993, ex vivo produced cells utilizing the Company's proprietary cell production technology were infused into seven patients with non-Hodgkin's lymphoma after they received myeloablative chemotherapy. These patients also received cells obtained from either an autologous bone marrow harvest or PBPC procedure. No safety issues attributable to the infused cells were observed in this trial and the patients exhibited recovery profiles consistent with traditional transplantation techniques. Aastrom completed the first feasibility trial of its cell production system technology under an IDE at the MD Anderson Cancer Center in October 1995. In this trial, ten breast cancer patients, who were subjected to myeloablative chemotherapy, were treated with cells obtained from a bone marrow harvest and with cells produced from a sample of such cells with a predecessor of the Aastrom CPS. The patients exhibited standard clinical recoveries, providing evidence of the clinical safety of cells obtained from the Company's cell production process and of the feasibility of cell production with a predecessor of the Aastrom CPS by clinical personnel at an investigational site. Aastrom is currently conducting a pre-pivotal stem cell therapy clinical trial under an IDE reviewed with the FDA. This clinical trial is designed to demonstrate that cells produced using the Aastrom CPS can provide hematopoietic recovery in accordance with trial endpoints in breast cancer patients who have received myeloablative chemotherapy. Bone marrow obtained from the patient by traditional methods will be available for precautionary reasons at defined clinical stages. The results from the five patients accrued at the first trial site have provided evidence of the clinical safety of the Aastrom CPS-produced cells in patients and that the hematopoietic recovery endpoints specified for the trial are achievable. The patients at this trial site were Stage IV breast cancer patients who had received significant prior cytotoxic therapies for their cancer. Four of these five patients received the precautionary back-up marrow pursuant to the trial protocol. Preliminary results from the first trial site were reviewed with the FDA, and the IDE was amended to expand the trial to a second site. The amended IDE provided for the enrollment of Stage II, III and IV patients, and a delayed use of the precautionary back-up bone marrow. As of the date of this Prospectus, patient accrual is ongoing and patient data from this site provides further evidence that the hematopoietic recovery endpoints specified for the trial are achievable. 28 The objective of the current and anticipated future trials is to establish the protocol for the pivotal trial of the Aastrom CPS in autologous stem cell therapy. Provided that these pre-pivotal trials provide evidence of feasibility and safety of the cells produced in the Aastrom CPS, the Company anticipates initiating a pivotal clinical trial at multiple sites, with the patient enrollment typical to support a PMA filing. See "Risk Factors-- Uncertainties Related to Preclinical and Clinical Testing." Aastrom, in partnership with Cobe, intends to initiate a clinical trial in France in early 1997 to evaluate the use of Aastrom CPS cells to promote hematopoietic recovery in breast cancer patients undergoing aggressive myelosuppressive chemotherapy. The Company intends to seek approval to market the Aastrom CPS in Europe through CE Mark Registration. See "--Government Regulation--Regulatory Process in Europe." The preliminary results of the Company's pre-pivotal trial may not be predictive of results that will be obtained from subsequent patients in the trial or from more extensive trials. Further, there can be no assurance that the Company's pre-pivotal or pivotal trial will be successful, or that PMA approval or required foreign regulatory approvals for the Aastrom CPS will be obtained in a timely fashion, or at all. BUSINESS STRATEGY Aastrom's objective is to build a leadership position in cell therapy process technology. The primary elements of the Company's business strategy are as follows: Establish Consumable Based Business Model. Aastrom's strategy is to sell the Aastrom CPS to institutions, hospitals, and other clinical care or commercial cell production facilities that are administering cell therapy. The Company plans to obtain ongoing revenue from the sale of single-use disposable Cell Cassettes and related cell culture media and reagents, which are utilized in individual cell therapy applications. After cells are cultured in the Cell Cassette, the cassette is discarded and a new cassette is utilized for a subsequent patient. Along with ongoing revenue from the sale of instruments and disposables for cell therapy applications, the Company believes it will be able to obtain license revenue from its stem cell therapy applications for its proprietary stem cell processes. Focus Initially on Established and Reimbursed Therapies. Aastrom will seek to establish the use of the Aastrom CPS in the field of stem cell therapy for the treatment of toxicity resulting from many cancer therapies, including those for breast cancer, lymphoma, ovarian cancer, germ cell cancers, leukemias and aplastic anemias. Stem cell therapy is a well-established and growing treatment modality in cancer therapy, and current cell collection procedures are widely reimbursed by third party payors. Leverage Platform Technology Across Multiple Market Opportunities. In addition to stem cell therapy applications, the Company believes that the Aastrom CPS may serve as a platform product that can be used to produce a variety of other cells for multiple therapeutic applications, such as T-cells for use in lymphocyte therapies, chondrocytes for cartilage replacement, and mesenchymal cells for use in certain solid tissue therapies. The Company believes that if the Aastrom CPS is well established as a method for cell production for use in stem cell therapy, the system will be positioned for commercialization of new cell and ex vivo gene therapies that are under development. Market Through Collaborative Relationships. The Company plans to reach end user markets through collaborative relationships with companies that have established positions in those markets. In 1993, the Company formed a strategic partnership with Cobe, a world leader in the marketing and distribution of blood cell processing equipment and disposables. Cobe is the Company's exclusive, worldwide distributor of the Aastrom CPS for stem cell therapy applications, not including stem cell gene therapy. The Company will seek to establish additional collaborations for other cell therapies as those therapies and the Company's product lines develop. See "Business--Strategic Relationships." 29 ADDITIONAL STEM CELL AND OTHER CELL THERAPIES The Company believes that the Aastrom CPS hardware and disposables may be developed to serve as platform products for application in a variety of other cell therapies in addition to stem cell therapy. The Company believes that the Aastrom CPS has the potential to supplant current manual cell culture methods to produce therapeutic quantities of cell types such as T-cells, chondrocytes, mesenchymal cells, keratinocytes, neuronal cells and dendritic cells. Currently such cells are often produced in specialized facilities generally using manual cell culture techniques which limit the effective commercialization of these cell types for therapy. Potential advantages of the Aastrom CPS in these therapies may include: (i) reducing labor and capital costs; (ii) enhancing process reliability; (iii) automating quality assurance; and (iv) reducing the need for environmentally controlled facilities. Modification of such processes and application of the Company's products to the expansion of other cell types may require substantial additional development of specialized culture environments and which may need to be incorporated within the Company's existing cell cassettes. There can be no assurances that the Company will be able to successfully modify or develop existing or future products to enable such additional cell production processes. Furthermore, other than a limited application of chondrocyte therapy, novel cell therapies are still in early stages of development by third parties. The Company's business opportunity is dependent upon successful development and regulatory approval of these novel cell therapies. No assurance can be given that such novel therapies will be developed or approved or that the Company's processes or product candidates will find successful application in such therapies. See "--Business Strategy" and "--Clinical Development" and "Use of Proceeds." Immunotherapies Immunotherapy involves using cells of the immune system to eradicate a disease target. T-cell lymphocytes and dendritic cells are being actively investigated by other companies for this purpose, and these procedures require ex vivo cell production. T-cells, a class of lymphocyte white blood cells, play a critical role in the human immune system and are responsible for the human immune response in a broad spectrum of diseases, including cancers and infectious diseases. Cytotoxic T-lymphocytes ("CTLs") is a new process that involves collecting T- cells from a patient and culturing them in an environment resulting in T-cells with specificity for a particular disease target. Clinical trials by third parties have been completed demonstrating CTL effectiveness for certain diseases. The ex vivo production of these cells under conditions for use in medical treatment represents a critical step in the advancement of this therapy. Dendritic cells (the potent antigen presenting cells) are believed to play an important role in the function of the immune system. Researchers believe that cultured dendritic cells could augment the natural ability of a patient to present antigens from the infectious agents to the immune system and aid in the generation of a cytotoxic T-cell response to the infectious agent. The Company intends to explore application of its products and processes for the expansion of dendritic cells. Solid Tissue Cell Therapies One of the newest areas of cell therapy involves the production of chondrocytes for the restoration of cartilage. Chondrocyte therapy involves the surgical removal of a small amount of tissue from the patient's knee and a therapeutic quantity of chondrocytes is produced from this surgical biopsy. The cells are then implanted into the patient's knee. Published reports indicate that such cells then reestablish mature articular cartilage. Currently, this cell production process is completed in highly specialized laboratory facilities using trained scientists and manual laboratory procedures. The Aastrom CPS has the potential to reduce costs associated with the cell production procedure and may eventually facilitate the transfer of the cell production capability away from specialized facilities directly to the clinical care sites. 30 Other Stem Cell Therapies Autoimmune Diseases. Stem cell therapy is under clinical investigation for the treatment of other diseases. Clinical studies have suggested a potential role for stem cell therapy in treatment of autoimmune diseases such as rheumatoid arthritis, multiple sclerosis and lupus erythematosus. The generic cause of these diseases is a malfunctioning immune system, including T- lymphocytes. Clinical trials in which the patient receives treatment resulting in immune ablation (usually involving myelotoxic cancer drugs or radiation), followed by stem cell therapy to restore the bone marrow and cells of the blood and immune system, have demonstrated remission of the autoimmune disease in some patients. Organ Transplantation. Recently, a number of academic and corporate researchers and companies have identified the potential use of stem cell therapy to facilitate successful solid organ and tissue transplants between human donors and recipients, as well as using organs from non-human species for transplantation into humans. These proposed applications are based on the observation that donor-specific bone marrow, infused concurrent with or prior to the organ transplant, can provide for reduction of the normal immune rejection response by the transplant recipient (e.g. heart, lung, liver or kidney transplants). A major limitation to the use of stem cell therapy in solid organ transplant is the limited availability of sufficient amounts of bone marrow to obtain a desired therapeutic response of immune tolerization. This limitation is particularly problematic when cadaveric donor organs are available, which has traditionally been the source of cells for these procedures. Bone marrow is also often available from the cadaveric donor, but only in a limited amount. Normally this amount may be sufficient for one transplant, but a donor might provide multiple organs for transplant into multiple recipients. Aastrom believes that the ability to expand the available bone marrow ex vivo will enhance the use of stem cell therapy for such transplant procedures. AASTROM PRODUCT CANDIDATES FOR EX VIVO GENE THERAPY A novel form of cell therapy is ex vivo gene therapy. For this type of cell therapy, cells procured from the patient or a donor are genetically modified prior to their infusion into the patient. Analogous to other cell therapies, the ability to produce a therapeutic dose of these gene-modified cells is a major limitation to the commercialization of these cell therapies. This limitation is further exacerbated by the additional requirement that the cells be genetically modified under conditions that are sterile and comply with GMP. Gene therapy is a therapeutic modality that holds the potential to significantly impact the delivery of healthcare and the delivery of therapeutically useful protein-based drugs within the body. Gene therapies are generally targeted at the introduction of a missing normal gene into otherwise defective human tissue, or the introduction of novel biologic capability into the body via the introduction of a gene not ordinarily present (for example, genes providing for the enhanced recognition and destruction or inhibition of the HIV-1 virus). The major developmental focus of the ex vivo gene therapy industry has been to identify the therapeutic gene of interest, insert it into a suitable vector that can be used to transport and integrate the gene into the DNA of the target cell, and then cause the gene to become expressed. For gene therapy to progress to clinical applications, a process to produce a sufficient quantity of therapeutic cells is required as is an efficient means to insert the gene vector into target cells. Gene therapy is still in an early stage of development by third parties. The Company's business opportunity is dependent upon the successful development and regulatory approval of individual gene therapy applications. No assurance can be given that such applications will be developed or approved or that the Company's processes or product candidates will find successful applications in such therapies. THE AASTROM CPS FOR GENE THERAPY (GT-CPS) The Aastrom CPS has been developed to produce cells for therapy. Clinical cell production is a limiting requirement for gene therapy to effectively move into medical practice, and as such, the Company believes that the Aastrom CPS may be useful in many potential ex vivo gene therapy applications. 31 Further, the Company's proprietary stem cell production process technology implemented by the Aastrom CPS provides the conditions for clinical scale stem cell division, and enables or enhances the introduction of therapeutic genes into stem cell DNA. The Company believes that its technology may also enable expansion of more mature progeny of these stem cells to create a gene therapy cell product with potential short and long term therapeutic effect. The Company has two principal objectives for the development of Aastrom GT- CPS: (i) the enablement of stem cell gene therapies for a variety of hematologic and other disorders, based on the GT-CPS's ability to enable large scale stem cell division ex vivo; and (ii) the enablement of gene transfer and therapeutic cell production by local and regional primary patient care facilities and ancillary service laboratories. THE AASTROM GENE LOADER The Aastrom Gene Loader product technology, which is under development, is being designed to transfer new therapeutic genes, which are carried by vectors into the target cell. This process, which is typically inefficient in many human cells, has represented a major hurdle preventing many ex vivo gene therapies from moving forward in the clinic. The Aastrom Gene Loader will incorporate the Company's proprietary directed motion gene transfer technology and is expected to incorporate single-use sterile disposables, operated by dedicated instrumentation. A major product objective of the Aastrom Gene Loader is the enhancement of gene transfer efficiencies and reliability. Improving gene vector efficiencies may enable a wide spectrum of gene therapies currently unable to realize clinical application. The Company believes that these issues represent a general bottleneck for other companies pursuing ex vivo gene therapy clinical applications. The Company's technology may favorably influence these gene therapy applications, the development of which are impeded due to low transduction efficiencies and the resultant need for use of extreme quantities of gene vectors and/or target "delivery" tissues. STRATEGIC RELATIONSHIPS On October 22, 1993, the Company entered into a Distribution Agreement (the "Distribution Agreement") with Cobe, a subsidiary of Gambro AB, for Cobe to be the Company's exclusive, worldwide distributor of the Aastrom CPS for stem cell therapy applications (the "Stem Cell Therapy Applications"). The Company has retained the right to market the Aastrom CPS for uses outside the Stem Cell Therapy Applications, such as for all gene therapy applications and for production of other cells and tissues. The initial term of the Distribution Agreement expires on October 22, 2003, and Cobe has the option to extend the term for an additional ten-year period. The Company is responsible for the expenses to obtain FDA and other regulatory approval in the United States, while Cobe is responsible for the expenses to obtain regulatory approval in foreign countries to allow for worldwide marketing of the Aastrom CPS for Stem Cell Therapy Applications. See "Risk Factors--Consequences of Cobe Relationship." Under the terms of the Distribution Agreement, the Company will realize approximately 60% and 58% of the net sales price at which Cobe ultimately sells the Aastrom CPS in the United States and Europe, respectively, for Stem Cell Therapy Applications, subject to certain negotiated discounts and volume- based adjustments. The Company is also entitled to a premium on United States sales in any year in which worldwide sales exceed specified levels. The Distribution Agreement may be terminated by Cobe upon twelve (12) months prior notice to the Company in the event that any person or entity other that Cobe beneficially owns more than 50% of the Company's outstanding Common Stock or voting securities. The Distribution Agreement may also be terminated by Cobe at any time after December 31, 1997 if Cobe determines that commercialization of the Aastrom CPS for stem cell therapy on or prior to December 31, 1998 is unlikely. 32 In conjunction with the Distribution Agreement, the Company also entered into a Stock Purchase Agreement with Cobe, whereby Cobe acquired certain option, registration, preemptive and other rights pertaining to shares of the Company's stock. See "Description of Capital Stock--Rights of Cobe." MANUFACTURING The Company has no current intention of internally manufacturing its product candidates and accordingly is developing relationships with third party manufacturers which are FDA registered as suppliers for the manufacture of medical products. On May 10, 1994, the Company entered into a Collaborative Product Development Agreement with SeaMED Corporation, ("SeaMED"). Pursuant to this agreement, the Company and SeaMED will collaborate on the further design of certain instrument components in the Aastrom CPS, and enable SeaMED to manufacture pre-production units of the instrument components for laboratory and clinical evaluation. The Company is paying SeaMED for its design and pre- production work on a "time and materials" basis, utilizing SeaMED's customary hourly billing rates and actual costs for materials. Subject to certain conditions, the Company has committed to enter into a manufacturing agreement with SeaMED for commercial manufacture of the instrument components for three years after shipment by SeaMED of the first commercial unit pursuant to a pricing formula set forth in the agreement. The Company retains all proprietary rights to its intellectual property which is utilized by SeaMED pursuant to this agreement. On November 8, 1994, the Company entered into a Collaborative Product Development Agreement with Ethox Corporation ("Ethox"). Pursuant to this Agreement, the Company and Ethox will collaborate on the further design of certain bioreactor assembly and custom tubing kit components of the Aastrom CPS, and enable Ethox to manufacture pre-production units of such components for laboratory and clinical evaluation. The Company is paying Ethox for its design and production work on a "time and materials" basis, utilizing Ethox's customary hourly billing rates and actual costs for materials. The Company retains all proprietary rights to its intellectual property which are utilized by Ethox pursuant to this Agreement. In April 1996, the Company entered into a five-year License and Supply Agreement with Immunex to purchase and resell certain cytokines and ancillary materials for use in conjunction with the Aastrom CPS. The agreement required the Company to pay Immunex an initial up-front fee of $1,500,000 to be followed by subsequent annual fee payments equal to $1,000,000 per year during the term of the agreement in addition to payment for supplies purchased by the Company. The agreement may be terminated by the Company at any time subject to the payment to Immunex of a specified amount for liquidated damages. Immunex may terminate the agreement in the event that the Company fails to purchase a minimum amount of its forecasted annual needs. There can be no assurance that the Company will be able to continue its present arrangements with its suppliers, supplement existing relationships or establish new relationships or that the Company will be able to identify and obtain the ancillary materials that are necessary to develop its product candidates in the future. The Company's dependence upon third parties for the supply and manufacture of such items could adversely affect the Company's ability to develop and deliver commercially feasible products on a timely and competitive basis. See "Risk Factors--Manufacturing and Supply Uncertainties; Dependence on Third Parties." PATENTS AND PROPRIETARY RIGHTS The Company's success depends in part on its ability, and the ability of its licensors, to obtain patent protection for its products and processes. The Company and its licensors are seeking patent protection for technologies related to (i) human stem and progenitor cell production processes; (ii) bioreactors and systems for stem and progenitor cell production and production of other cells; and (iii) gene transfer devices and processes. The Company has exclusive license rights to five issued United States patents that together claim (i) certain methods for ex vivo stem cell division and stable genetic transformation, optimization of hematopoietic progenitor cell cultures and increasing the metabolism or growth factor secretion of stromal cells, in a 33 continuously or periodically perfused liquid culture medium; (ii) certain devices for the simultaneous culture of stem cells and hematopoietic cells; and (iii) certain methods of infecting or transfecting target cells with genetic vectors. Patents equivalent to two of these United States patents have also been issued in other jurisdictions: one in Australia and another in Canada and under the European Patent Convention. These eight issued patents are due to expire beginning in 2006, through 2013. In addition, the Company and its exclusive licensors have filed applications for patents in the United States and equivalent applications in certain other countries claiming other aspects of the Company's products and processes, including five United States patent applications and corresponding applications in other countries related to various components of the Aastrom CPS. Of these pending patent applications, the Company has received notices of allowance for certain claims in a United States application relating to methods for obtaining ex vivo stem cell division, and claims in a European Patent Convention application and in a United States application relating to methods for efficient proliferation of hematopoietic cells in culture. The validity and breadth of claims in medical technology patents involve complex legal and factual questions and, therefore, may be highly uncertain. No assurance can be given that any patents based on pending patent applications or any future patent applications of the Company or its licensors will be issued, that the scope of any patent protection will exclude competitors or provide competitive advantages to the Company, that any of the patents that have been or may be issued to the Company or its licensors will be held valid if subsequently challenged or that others will not claim rights in or ownership of the patents and other proprietary rights held or licensed by the Company. Furthermore, there can be no assurance that others have not developed or will not develop similar products, duplicate any of the Company's products or design around any patents that have been or may be issued to the Company or its licensors. Since patent applications in the United States are maintained in secrecy until patents issue, the Company also cannot be certain that others did not first file applications for inventions covered by the Company's and its licensors' pending patent applications, nor can the Company be certain that it will not infringe any patents that may issue to others on such applications. The Company relies on certain licenses granted by the University of Michigan and Dr. Cremonese for the majority of its patent rights. If the Company breaches such agreements or otherwise fails to comply with such agreements, or if such agreements expire or are otherwise terminated, the Company may lose its rights under the patents held by the University of Michigan and Dr. Cremonese, which would have a material adverse effect on the Company's business, financial condition and results of operation. See "--University of Michigan Research Agreement and License Agreement" and "--License Agreement with J.G. Cremonese." The Company also relies on trade secrets and unpatentable know-how which it seeks to protect, in part, by confidentiality agreements. It is the Company's policy to require its employees, consultants, contractors, manufacturers, outside scientific collaborators and sponsored researchers, and other advisors to execute confidentiality agreements upon the commencement of employment or consulting relationships with the Company. These agreements provide that all confidential information developed or made known to the individual during the course of the individual's relationship with the Company is to be kept confidential and not disclosed to third parties except in specific limited circumstances. The Company also requires signed confidentiality or material transfer agreements from any company that is to receive its confidential data. In the case of employees, consultants and contractors, the agreements generally provide that all inventions conceived by the individual while rendering services to the Company shall be assigned to the Company as the exclusive property of the Company. There can be no assurance, however, that these agreements will not be breached, that the Company would have adequate remedies for any breach, or that the Company's trade secrets or unpatentable know-how will not otherwise become known or be independently developed by competitors. The Company's success will also depend in part on its ability to develop commercially viable products without infringing the proprietary rights of others. The Company has not conducted freedom of use patent searches and no assurance can be given that patents do not exist or could not be filed which would have an adverse effect on the Company's ability to market its products or maintain its competitive position with respect to its products. If the Company's technology components, devices, designs, products, processes or other subject matter are claimed under other existing United States or foreign patents or are otherwise protected by third party 34 proprietary rights, the Company may be subject to infringement actions. In such event, the Company may challenge the validity of such patents or other proprietary rights or be required to obtain licenses from such companies in order to develop, manufacture or market its products. There can be no assurances that the Company would be able to obtain such licenses or that such licenses, if available, could be obtained on commercially reasonable terms. Furthermore, the failure to either develop a commercially viable alternative or obtain such licenses could result in delays in marketing the Company's proposed products or the inability to proceed with the development, manufacture or sale of products requiring such licenses, which could have a material adverse effect on the Company's business, financial condition and results of operations. If the Company is required to defend itself against charges of patent infringement or to protect its own proprietary rights against third parties, substantial costs will be incurred regardless of whether the Company is successful. Such proceedings are typically protracted with no certainty of success. An adverse outcome could subject the Company to significant liabilities to third parties and force the Company to curtail or cease its development and sale of its products and processes. Certain of the Company's and its licensors' research has been or is being funded in part by the Department of Commerce and by a Small Business Innovation Research Grant obtained from the Department of Health and Human Services. As a result of such funding, the United States Government has certain rights in the technology developed with the funding. These rights include a non-exclusive, paid-up, worldwide license under such inventions for any governmental purpose. In addition, the government has the right to require the Company to grant an exclusive license under any of such inventions to a third party if the government determines that (i) adequate steps have not been taken to commercialize such inventions, (ii) such action is necessary to meet public health or safety needs or (iii) such action is necessary to meet requirements for public use under federal regulations. Additionally, under the federal Bayh Dole Act, a party which acquires an exclusive license for an invention that was partially funded by a federal research grant is subject to the following government rights: (i) products using the invention which are sold in the U.S. are to be manufactured substantially in the U.S., unless a waiver is obtained; (ii) if the licensee does not pursue reasonable commercialization of a needed product using the invention, the government may force the granting of a license to a third party who will make and sell the needed product; and (iii) the U.S. government may use the invention for its own needs. UNIVERSITY OF MICHIGAN RESEARCH AGREEMENT AND LICENSE AGREEMENT In August 1989, the Company entered into a Research Agreement ("Research Agreement") with the University, pursuant to which the Company funded a research project at the University under the direction of Stephen G. Emerson, M.D., Ph.D., as the principal inventor, together with Michael F. Clarke, M.D., and Bernhard O. Palsson, Ph.D., as co-inventors. Pursuant to this Research Agreement, the Company was granted the right to acquire an exclusive, worldwide license to utilize all inventions, know-how and technology derived from the research project. By Extension Agreements, the Company and the University extended the scope and term of Research Agreement through December, 1994. On March 13, 1992, the Company and the University entered into the License Agreement, as contemplated by the Research Agreement. There have been clarifying amendments to the License Agreement, dated March 13, 1992, October 8, 1993 and June 21, 1995. Pursuant to this License Agreement, (i) the Company acquired exclusive worldwide license rights to the patents and know-how for the production of blood cells and bone marrow cells as described in the University's research project or which resulted from certain further research conducted through December 31, 1994, and (ii) the Company is obligated to pay to the University a royalty equal to 2% of the net sales of products which are covered by the University's patents. Unless it is terminated earlier at the Company's option or due to a material breach by the Company, the License Agreement will continue in effect until the latest expiration date of the patents to which the License Agreement applies. LICENSE AGREEMENT WITH J. G. CREMONESE In July 1992, the Company entered into a License Agreement with Joseph G. Cremonese pursuant to which the Company obtained exclusive worldwide license rights for all fields of use, to utilize U.S. Patent No. 4,839,292, entitled "Cell Culture Flask Utilizing a Membrane Barrier," which patent was issued to 35 Dr. Cremonese on June 13, 1989, and to utilize any other related patents that might be issued to Dr. Cremonese. Pursuant to this License Agreement, the Company has reimbursed Dr. Cremonese for $25,000 of his patent costs. Under the terms of the License Agreement, the Company is to pay to Dr. Cremonese a royalty of 3% of net sales of the products which are covered by said patent, subject to specified minimum royalty payments ranging from $20,000 to $50,000 per year, commencing in calendar year 1997. Unless it is terminated earlier at the Company's option or due to default by the Company, the License Agreement will continue in effect until the latest expiration date of the patents to which the License Agreement applies. GOVERNMENT REGULATION The Company's research and development activities and the manufacturing and marketing of the Company's products are subject to the laws and regulations of governmental authorities in the United States and other countries in which its products will be marketed. Specifically, in the United States the FDA, among other activities, regulates new product approvals to establish safety and efficacy of these products. Governments in other countries have similar requirements for testing and marketing. In the U.S., in addition to meeting FDA regulations, the Company is also subject to other federal laws, such as the Occupational Safety and Health Act and the Environmental Protection Act, as well as certain state laws. REGULATORY PROCESS IN THE UNITED STATES To the Company's knowledge, it is the first to develop a culture system for ex vivo human cell production to be sold for therapeutic applications. Therefore, to a certain degree, the manner in which the FDA will regulate the Company's products is uncertain. The Company's products are potentially subject to regulation as medical devices under the Federal Food, Drug, and Cosmetic Act, and as biological products under the Public Health Service Act, or both. Different regulatory requirements may apply to the Company's products depending on how they are categorized by the FDA under these laws. To date, the FDA has indicated that it intends to regulate the Aastrom CPS product for stem cell therapy as a Class III medical device through the Center for Biologics Evaluation and Research. However, there can be no assurance that FDA will ultimately regulate the Aastrom CPS as a medical device. Further, it is unclear whether the FDA will separately regulate the cell therapies derived from the Aastrom CPS. The FDA is still in the process of developing its requirements with respect to somatic cell therapy and gene cell therapy products and has recently issued a draft document concerning the regulation of umbilical cord blood stem cell products. If the FDA adopts the regulatory approach set forth in the draft document, the FDA may require separate regulatory approval for such cells in some cases. The FDA also recently proposed a new type of license, called a biologic license application ("BLA"), for autologous cells manipulated ex vivo and intended for structural repair or reconstruction. This proposal may indicate that the FDA will extend a similar approval requirement to other types of autologous cellular therapies, such as autologous cells for stem cell therapy. Any such additional regulatory or approval requirements could significantly delay the introduction of the Company's product candidates to the market, and have a material adverse impact on the Company. Approval of new medical devices and biological products is a lengthy procedure leading from development of a new product through preclinical and clinical testing. This process takes a number of years and the expenditure of significant resources. There can be no assurance that the Company's product candidates will ultimately receive regulatory approval. Regardless of how the Company's product candidates are regulated, the Federal Food, Drug, and Cosmetic Act and other Federal statutes and regulations govern or influence the research, testing, manufacture, safety, labeling, storage, recordkeeping, approval, distribution, use, reporting, advertising and promotion of such products. Noncompliance with applicable requirements can result in civil penalties, recall, injunction or seizure of products, refusal of the government to approve or clear product approval applications or to allow the Company to enter into government supply contracts, withdrawal of previously approved applications and criminal prosecution. 36 DEVICES In order to obtain FDA approval of a new medical device sponsors must generally submit proof of safety and efficacy. In some cases, such proof entails extensive clinical and preclinical laboratory tests. The testing, preparation of necessary applications and processing of those applications by the FDA is expensive and may take several years to complete. There can be no assurance that the FDA will act favorably or in a timely manner in reviewing submitted applications, and the Company may encounter significant difficulties or costs in its efforts to obtain FDA approvals which could delay or preclude the Company from marketing any products it may develop. The FDA may also require postmarketing testing and surveillance of approved products, or place other conditions on the approvals. These requirements could cause it to be more difficult or expensive to sell the products, and could therefore restrict the commercial applications of such products. Product approvals may be withdrawn if compliance with regulatory standards is not maintained or if problems occur following initial marketing. For patented technologies, delays imposed by the governmental approval process may materially reduce the period during which the Company will have the exclusive right to exploit such technologies. If human clinical trials of a proposed device are required and the device presents significant risk, the manufacturer or distributor of the device will have to file an IDE application with the FDA prior to commencing human clinical trials. The IDE application must be supported by data, typically including the results of pre-clinical and laboratory testing. If the IDE application is approved, human clinical trials may commence at a specified number of investigational sites with the number of patients approved by the FDA. The FDA categorizes devices into three regulatory classifications subject to varying degrees of regulatory control. In general, Class I devices require compliance with labeling and recordkeeping regulations, GMPs, 510(k) pre- market notification, and are subject to other general controls. Class II devices may be subject to additional regulatory controls, including performance standards and other special controls, such as postmarket surveillance. Class III devices, which are either invasive or life-sustaining products, or new products never before marketed (for example, non- "substantially equivalent" devices), require clinical testing to demonstrate safety and effectiveness and FDA approval prior to marketing and distribution. The FDA also has the authority to require clinical testing of Class I and Class II devices. If a manufacturer or distributor of medical devices cannot establish that a proposed device is substantially equivalent, the manufacturer or distributor must submit a PMA application to the FDA. A PMA application must be supported by extensive data, including preclinical and human clinical trial data, to prove the safety and efficacy of the device. Upon receipt, the FDA conducts a preliminary review of the PMA application. If sufficiently complete, the submission is declared filed by the FDA. By regulation, the FDA has 180 days to review a PMA application once it is filed, although PMA application reviews more often occur over a significantly protracted time period, and may take approximately one year or more from the date of filing to complete. Some of the Company's products may be classified as Class II or Class III medical devices. The Company has submitted and obtained FDA approval for several IDEs for the Aastrom CPS, and is currently conducting clinical studies under these IDEs. The Company believes that the Aastrom CPS product will be regulated by the FDA as a Class III device, although there can be no assurance that the FDA will not choose to regulate this product in a different manner. The Company and any contract manufacturer are required to be registered as a medical device manufacturer with the FDA. As such, they will be inspected on a routine basis by the FDA for compliance with the FDA's GMP regulations. These regulations will require that the Company and any contract manufacturer manufacture products and maintain documents in a prescribed manner with respect to manufacturing, testing, distribution, storage, design control and service activities, and that adequate design and service controls are implemented. The Medical Device Reporting regulation requires that the Company provide information to the FDA on deaths or serious injuries alleged to be associated with the use of its devices, as well as product malfunctions that are 37 likely to cause or contribute to death or serious injury if the malfunction were to recur. In addition, the FDA prohibits a company form promoting an approved device for unapproved applications and reviews company labeling for accuracy. BIOLOGICAL PRODUCTS For certain of the Company's new products which may be regulated as biologics, the FDA requires (i) preclinical laboratory and animal testing, (ii) submission to the FDA of an investigational new drug ("IND") application which must be effective prior to the initiation of human clinical studies, (iii) adequate and well-controlled clinical trials to establish safety and efficacy of the product for its intended use, (iv) submission to the FDA of a product license application ("PLA") and establishment license application ("ELA") and (v) review and approval of the PLA and ELA as well as inspections of the manufacturing facility by the FDA prior to commercial marketing of the product. Preclinical testing covers laboratory evaluation of product chemistry and formulation as well as animal studies to assess the safety and efficacy of the product. The results of these tests are submitted to the FDA as part of the IND. Following the submission of an IND, the FDA has 30 days to review the application and raise safety and other clinical trial issues. If the Company is not notified of objections within that period, clinical trials may be initiated. Clinical trials are typically conducted in three sequential phases. Phase I represents the initial administration of the drug or biologic to a small group of humans, either healthy volunteers or patients, to test for safety and other relevant factors. Phase II involves studies in a small number of patients to assess the efficacy of the product, to ascertain dose tolerance and the optimal dose range and to gather additional data relating to safety and potential adverse effects. Once an investigational drug is found to have some efficacy and an acceptable safety profile in the targeted patient population, multi-center Phase III studies are initiated to establish safety and efficacy in an expanded patient population and multiple clinical study sites. The FDA reviews both the clinical plans and the results of the trials and may request the Company to discontinue the trials at any time if there are significant safety issues. The results of the preclinical tests and clinical trials are submitted to the FDA in the form of a PLA for marketing approval. The testing and approval process is likely to require substantial time and effort and there can be no assurance that any approval will be granted on a timely basis, if at all. Additional animal studies or clinical trials may be requested during the FDA review period that may delay marketing approval. After FDA approval for the initial indications, further clinical trials may be necessary to gain approval for the use of the product for additional indications. The FDA requires that adverse effects be reported to the FDA and may also require post-marketing testing to monitor for adverse effects, which can involve significant expense. Under current requirements, facilities manufacturing biological products must be licensed. To accomplish this, an ELA must be filed with the FDA. The ELA describes the facilities, equipment and personnel involved in the manufacturing process. An establishment license is granted on the basis of inspections of the applicant's facilities in which the primary focus is on compliance with GMP and the ability to consistently manufacture the product in the facility in accordance with the PLA. If the FDA finds the inspection unsatisfactory, it may decline to approve the ELA, resulting in a delay in production of products. Although reviewed separately, approval of both the PLA and ELA must be received prior to commercial marketing of a cellular biologic. As part of the approval process for human biological products, each manufacturing facility must be registered and inspected by FDA prior to marketing approval. In addition, state agency inspections and approvals may also be required for a biological product to be shipped out of state. REGULATORY PROCESS IN EUROPE The Company believes that the Aastrom CPS will be regulated in Europe as a Class IIb medical device, under the authority of the new Medical Device Directives ("MDD") being implemented by European Union ("EU") member countries. This classification applies to medical laboratory equipment and supplies including, 38 among other products, many devices that are used for the collection and processing of blood for patient therapy. Certain ancillary products (e.g., biological reagents) used with the Aastrom CPS may be considered Class III medical devices. The MDD regulations vest the authority to permit affixing of the "CE Mark" with various "Notified Bodies." These are private and state organizations which operate under license from the EU to certify that appropriate quality assurance standards and compliance procedures are followed by developers and manufacturers of medical device products or, alternatively, that a manufactured medical product meets a more limited set of requirements. Notified Bodies are also charged with responsibility for determination of the appropriate standards to apply to a medical product. Receipt of permission to affix the CE Mark enables a company to sell a medical device in all EU member countries. Other registration requirements may also need to be satisfied in certain countries, although there is a general trend among EU member countries not to impose additional requirements beyond those specified for CE Mark certification. COMPETITION The biotechnology and medical device industries are characterized by rapidly evolving technology and intense competition. The Company's competitors include major pharmaceutical, medical device, medical products, chemical and specialized biotechnology companies, many of which have financial, technical and marketing resources significantly greater than those of the Company. In addition, many biotechnology companies have formed collaborations with large, established companies to support research, development and commercialization of products that may be competitive with those of the Company. Academic institutions, governmental agencies and other public and private research organizations are also conducting research activities and seeking patent protection and may commercialize products on their own or through joint ventures. The Company's product development efforts are primarily directed toward obtaining regulatory approval to market the Aastrom CPS for stem cell therapy. That market is currently dominated by the bone marrow harvest and PBPC collection methods. The Company's clinical data, although early, is inconclusive as to whether or not cells expanded in the Aastrom CPS will enable hematopoietic recovery within the time frames currently achieved by the bone marrow harvest and PBPC collection methods. In addition, the bone marrow harvest and PBPC collection methods have been widely practiced for a number of years and, recently, the patient costs associated with these procedures have begun to decline. There can be no assurance that the Aastrom CPS method, if approved for marketing, will prove to be competitive with these established collection methods on the basis of hematopoietic recovery time, cost or otherwise. The Company is aware of certain other products manufactured or under development by competitors that are used for the prevention or treatment of certain diseases and health conditions which the Company has targeted for product development. In particular, the Company is aware that competitors such as Amgen, Inc., CellPro, Incorporated, Systemix, Inc., Baxter Healthcare Corp. and RPR are in advanced stages of development of technologies and products for use in stem cell therapy and other market applications currently being pursued by the Company. In addition, Cobe, a significant stockholder of the Company, is a market leader in the blood cell processing products industry and, accordingly, a potential competitor of the Company. There can be no assurance that developments by others will not render the Company's product candidates or technologies obsolete or noncompetitive, that the Company will be able to keep pace with new technological developments or that the Company's product candidates will be able to supplant established products and methodologies in the therapeutic areas that are targeted by the Company. The foregoing factors could have a material adverse effect on the Company's business, financial condition and results of operations. The Company's products under development are expected to address a broad range of existing and new markets. The Company believes that its stem cell therapy products will, in large part, face competition by existing procedures rather than novel new products. The Company's competition will be determined in part by the potential indications for which the Company's products are developed and ultimately approved by regulatory authorities. In addition, the first product to reach the market in a therapeutic or preventive area is often at a significant competitive advantage relative to later entrants to the market. Accordingly, the relative speed with 39 which the Company or its corporate partners can develop products, complete the clinical trials and approval processes and supply commercial quantities of the products to the market are expected to be important competitive factors. The Company's competitive position will also depend on its ability to attract and retain qualified scientific and other personnel, develop effective proprietary products, develop and implement production and marketing plans, obtain and maintain patent protection and secure adequate capital resources. The Company expects its products, if approved for sale, to compete primarily on the basis of product efficacy, safety, patient convenience, reliability, value and patent position. FACILITIES The Company leases approximately 20,000 square feet of office and research and development space in Ann Arbor, Michigan under a lease agreement expiring in May 1998. The lease is renewable at the option of the Company for up to an additional five-year term. The Company believes that its facilities will be adequate for its currently anticipated needs. Contract manufacturing or additional facilities will be required in the future to support expansion of research and development and to manufacture products. EMPLOYEES As of September 30, 1996, the Company employed approximately 61 individuals full-time. A significant number of the Company's management and professional employees have had prior experience with pharmaceutical, biotechnology or medical product companies. None of the Company's employees are covered by collective bargaining agreements, and management considers relations with its employees to be good. LEGAL PROCEEDINGS The Company is not party to any material legal proceedings, although from time to time it may become involved in disputes in connection with the operation of its business. 40 MANAGEMENT DIRECTORS AND EXECUTIVE OFFICERS The following table provides information concerning directors and executive officers of the Company:

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS The Company has adopted provisions in its Restated Articles of Incorporation that limit the liability of its directors for monetary damages arising from a breach of their fiduciary duty as directors, except under certain circumstances which include breach of the director's duty of loyalty to the Company or its shareholders, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of the law. The Company's Bylaws provide that the Company shall indemnify its directors to the fullest extent authorized or permitted by the Michigan Business Corporation Act. Additionally, the Company has entered into an Indemnification Agreement, originally dated as of December 14, 1993 (the "Indemnification Agreement"), with certain of its directors, officers and other key personnel, which may, in certain cases, be broader than the specific indemnification provisions contained under applicable law. The Indemnification Agreement may require the Company, among other things, to indemnify such officers, directors and key personnel against certain liabilities that may arise by reason of their status or service as directors, officers or employees of the Company, to advance the expenses incurred by such parties as a result of any threatened claims or proceedings brought against them as to which they could be indemnified, and to cover such officers, directors and key employees under the Company's directors' and officers' liability insurance policies to the maximum extent that insurance coverage is maintained. At present, there is no pending litigation or proceeding involving a director, officer, employee or agent of the Company where indemnification by the Company will be required or permitted. The Company is not aware of any threatened litigation or proceeding which may result in a claim for such indemnification. 43 EXECUTIVE COMPENSATION The following table summarizes the compensation paid to or earned by the Company's Chief Executive Officer and all other executive officers of the Company whose salary and bonus for services rendered in all capacities to the Company during the fiscal year ended June 30, 1996 exceeded $100,000 (the "named executive officers"): SUMMARY COMPENSATION TABLE

If the Common Stock price of $1.20 on the date of grant for the options granted in 1996 were to appreciate at the rates indicated, it would be $1.95 per share (at a 5% compounded appreciation) and $3.11 per share (at a 10% compounded appreciation) on the date of expiration of those options. 44 Option Exercises and Year-End Values The following table provides information about the number of shares issued upon option exercise by the named executive officers during 1996, and the value realized by the named executive officers.

- -------- (1) The option value represents fair market value of the underlying securities on the exercise date minus the aggregate exercise price of such options, multiplied by the number of shares of Common Stock subject to the option. For purposes of this calculation, a fair market value of $3.20 per share was used, the fair market value of the securities as determined by the Board of Directors on June 30, 1996. No compensation intended to serve as incentive for performance to occur over a period longer than one fiscal year was paid pursuant to a long-term incentive plan during the last fiscal year to any of the persons named in the Summary Compensation Table. The Company does not have any defined benefit or actuarial plan with any of the persons named in the Summary Compensation Table under which benefits are determined primarily by final compensation or average final compensation and years of service. EMPLOYMENT AGREEMENTS The Company has a policy of entering into employment agreements with all of its employees, and has entered into such agreements with all of its executive officers other than Dr. Armstrong. Such employment agreements generally establish salary levels (which are subject to periodic review) and provide for customary fringe benefits such as vacation leave, sick leave and health insurance. The agreements also generally provide for the protection of confidential information and the assignment to the Company of inventions conceived by the employee during his or her employment and permit the termination of the employment relationship by either party upon fourteen days prior written notice. The following is a summary of the employment agreements between the Company and its executive officers. The Company entered into employment agreements with no defined terms with James Maluta, Walter C. Ogier, Thomas E. Muller, Ph.D., Alan K. Smith, Ph.D. and Todd E. Simpson in June 1992, February 1994, April 1994, October 1995 and December 1995, respectively. Pursuant to these agreements, the Company agreed to pay Messrs. Maluta, Ogier, Muller, Smith and Simpson annual base salaries of $90,000, $87,500, $110,000, $122,500 and $122,500, certain of which base salaries have been increased by the Board of Directors and are subject to annual review and adjustment. Pursuant to the terms of the foregoing employment agreements, either party may generally terminate the employment relationship without cause at any time upon 14 days prior written notice to the other party or immediately with cause upon notice. 45 STOCK OPTION AND EMPLOYEE BENEFIT PLANS 1989 STOCK OPTION PLAN In 1989, the Company established the 1989 Stock Option Plan. As of September 30, 1996, options to purchase an aggregate of 932,266 shares of Common Stock have been exercised at $0.15 per share. Options to purchase 13,127 shares of Common Stock at $0.15 per share were cancelled unexercised. No additional shares remain available for grant under the 1989 Stock Option Plan. ANCILLARY PLAN In 1991, the Company established an Ancillary Plan to grant options to individuals who were not eligible to receive options under the 1989 Stock Option Plan. Options to purchase an aggregate of 7,498 shares of the Company's Common Stock were granted under the Ancillary Plan, of which options to purchase 4,328 shares have been exercised at $0.15 per share and the remaining options to purchase 3,170 shares have been cancelled. No additional shares remain available for grant under the Ancillary Plan. AMENDED AND RESTATED 1992 INCENTIVE AND NON-QUALIFIED STOCK OPTION PLAN In 1992, the Company adopted the 1992 Incentive and Non-Qualified Stock Option Plan (the "1992 Plan"), providing for the grant of options to purchase 666,667 shares of Common Stock. The Company allocated an additional 100,000 shares of Common Stock during 1992, an additional 333,333 shares of Common Stock in 1994 and an additional 800,000 shares of Common Stock in 1996 to the 1992 Plan, resulting in a total share reserve of 1,900,000 shares. The 1992 Plan was amended and restated to its current form in 1996. Options under the 1992 Plan for a total of 462,840 shares have been exercised as of September 30, 1996. As of September 30, 1996, options to purchase 336,254 shares of Common Stock were outstanding with a weighted average exercise price of $1.27 per share. The 1992 Plan provides for grants to employees and officers of "incentive stock options" within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended, provided that such employee or officer is an employee on the date of grant. The 1992 Plan also provides for grants to employees, officers, consultants or service providers of nonqualified stock options. The 1992 Plan previously has been administered by the Board of Directors, but is currently administered by the Compensation Committee of the Board of Directors (the "Committee"). Each option granted pursuant to the 1992 Plan is authorized by the Committee and evidenced by a notice in such form as the Committee may from time to time determine. The exercise price of each incentive stock option granted under the 1992 Plan must be at least equal to the fair market value of a share of Common Stock on the date of grant, except for incentive stock options granted to individuals who, at the time of grant, own stock possessing more than 10% of the total combined voting power of the Company, which options must have an exercise price of at least 110% of the fair market value of a share of Common Stock on the date of grant and must expire five years from the date of grant. The exercise price of each nonqualified stock option granted under the 1992 Plan must be at least 85% of the fair market value of the shares on the date of grant. No option shall be treated as an incentive stock option to the extent that such option would cause the aggregate fair market value (determined as of the date of grant of such option) of the shares with respect to which incentive stock options are exercisable by such optionee for the first time during any calendar year to exceed $100,000. The terms of all incentive stock options and nonqualified stock options granted under the 1992 Plan may not exceed ten years. The exercise price may be paid in cash or, at the Committee's discretion, by delivery of previously owned shares of the Company's Common Stock, by a combination of cash and shares, or any other form of legal consideration acceptable to the Committee. Options under the 1992 Plan generally may not be granted after April 2006. 46 The 1992 Plan provides that if the Company is a party to any merger in which the Company is not the surviving entity, any consolidation or dissolution (other than the merger or consolidation of the Company with one or more of its wholly-owned subsidiaries), the Company must cause any successor corporation to assume the options or substitute similar options for outstanding option or continue such options in effect. In the event that any successor to the Company in a merger, consolidation or dissolution will not assume the options or substitute similar options, then with respect to options held by optionees performing services for the Company, the time for exercising such options will be accelerated and such options will be terminated if not exercised prior to such merger, consolidation or dissolution. 1996 OUTSIDE DIRECTORS STOCK OPTION PLAN A total of 150,000 shares of Common Stock have been reserved for issuance under the Company's 1996 Outside Directors Stock Option Plan (the "Directors Plan"). As of the effective date of this offering, no options have been granted under the Directors Plan. The Directors Plan provides for the automatic granting of non-qualified stock options to directors of the Company who are not employees of the Company ("Outside Directors"). Under the Directors Plan, each Outside Director serving on the effective date of this Offering or elected after the date of this offering will automatically be granted an option to purchase 5,000 shares of Common Stock on the effective date of this offering or on the date of his or her election or appointment. In addition, each serving Outside Director will thereafter automatically be granted an option to purchase 5,000 shares of Common Stock following each annual meeting of stockholders after their election, provided that the Outside Director continues to serve in such capacity and that the Outside Director has served continuously as a director for at least six months. The exercise price of the options in all cases will be equal to the fair market value of the Common Stock on the date of grant. Options granted under the Directors Plan generally vest over a one-year period in equal monthly installments and must be exercised within ten years from the date of grant. 1996 EMPLOYEE STOCK PURCHASE PLAN A total of 250,000 shares of the Company's Common Stock have been reserved for issuance under the Company's 1996 Employee Stock Purchase Plan (the "Purchase Plan"), none of which have been issued. The Purchase Plan permits eligible employees to purchase Common Stock at a discount through payroll deductions, during sequential 24-month offering periods. Each offering period is divided into four consecutive six-month purchase periods. Unless otherwise provided by the Board of Directors prior to the commencement of an offering period, the price at which stock is purchased under the Purchase Plan for such offering period is equal to 85% of the lesser of the fair market value of the Common Stock on the first day of such offering period or the last day of the purchase period of such offering period. The initial offering period will commence on the effective date of this offering. SECTION 401(K) PLAN Effective January 1, 1994, the Company adopted the Aastrom Biosciences, Inc. 401(k) Plan (the "Plan"). The Plan is intended to be a qualified retirement plan under the Internal Revenue Code. Employees of the Company are eligible to participate in the Plan upon the completion of three consecutive months of employment. Participants may make salary deferral contributions to the Plan of up to 15% of compensation, subject to the limitations imposed under the Internal Revenue Code. The Company may, but is not required to, make matching contributions to the Plan based on the participants' salary-defined contributions. Employer contributions are subject to a graduated vesting schedule based upon an employee's years of service with the Company. It is not anticipated that the Company will make any contributions to the Plan for the 1997 Plan Year. All contributions to the Plan are held in a trust which is intended to be exempt from income tax under Section 501(a) of the Internal Revenue Code. The Plan's trustees are R. Douglas Armstrong and Todd E. Simpson. Participants may direct the investment of their contributions among specified Merrill Lynch investment funds. The Plan may be amended or terminated by the Company at any time, subject to certain restrictions imposed by the Internal Revenue Code and the Employee Retirement Income Security Act of 1974. 47 COMPENSATION OF DIRECTORS Directors of the Company do not receive cash for services provided as a director, however, directors who are not employees of the Company will receive annual grants of options to purchase Common Stock in accordance with the Directors Plan. No stock options nor any other form of non-cash compensation was granted to directors of the Company during the Company's fiscal year ending June 30, 1996. See "Stock Option and Employee Benefit Plans--1996 Outside Directors Stock Option Plan." COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION IN COMPENSATION DECISIONS During the fiscal year ended June 30, 1996, Robert J. Kunze, formerly an officer of the Company until 1991, R. Douglas Armstrong, President and Chief Executive Officer of the Company, and G. Bradford Jones were the members of the Compensation Committee of the Board of Directors. Dr. Armstrong resigned from the Compensation Committee and was replaced by Albert B. Deisseroth, M.D., Ph.D. on April 30, 1996, however, Mr. Kunze continues to be a member of this committee. 48 CERTAIN TRANSACTIONS During the last three fiscal years, the Company sold Preferred Stock to certain holders of more than 5% of the outstanding shares of the Company, or to their affiliates, as described below. In April 1995, the Company sold 775,001 shares of Series D Preferred Stock at a price per share of $4.00 to the following investors: (i) H&Q Life Science Technology Fund I purchased 167,001 shares for a purchase price of $668,004, (ii) H&Q London Ventures purchased 100,000 shares for a purchase price of $400,000, (iii) Brentwood Associates V, L.P. ("Brentwood") purchased 231,250 shares for a purchase price of $925,000, (iv) Windpoint Partners II, L.P. purchased 89,250 shares for a purchase price of $357,000, and (v) the State Treasurer of the State of Michigan ("Michigan") purchased 187,500 shares for a purchase price of $750,000. In May 1995, Cobe purchased 1,250,000 shares of Series D Preferred Stock for a purchase price of $5,000,000. Upon the closing of this offering, each outstanding share of Series D Preferred Stock will be converted into two-thirds of a share of Common Stock. In April 1995, Dr. Armstrong and Dr. Emerson agreed to grant to Brentwood an option to purchase up to 28,000 shares and 14,667 shares of Common Stock, respectively, and, together with two other shareholders of the Company, an aggregate of up to 66,667 shares of Common Stock at a purchase price of $100,000. Brentwood exercised this option in April, 1996 purchasing an aggregate of 66,667 shares of Common Stock at a purchase price of $100,000 from such shareholders. In September 1995, the Company and RPR entered into a collaborative relationship for use of the Aastrom CPS as a component of its lymphoid cell therapy program. On September 6, 1996, RPR notified the Company that it would not exercise its option to continue the collaboration. As a result, $3,500,000 million of option payments previously paid to the Company by RPR were converted into 205,882 shares of the Company's Series E Preferred Stock. In October 1995, the Company repurchased 62,500 shares of Series D Preferred Stock from Brentwood at the original purchase price of $250,000 and in December 1995 resold these shares to Northwest Ohio Venture Fund, a shareholder of the Company, for a total purchase price of $250,000. In January 1996, the Company sold 1,411,765 shares of Series E Preferred Stock at a price per share of $4.25 to the following investors: (i) Michigan purchased 470,588 shares for a total purchase price of $1,999,999, and (ii) SBIC Partners, L.P. purchased 941,777 shares for a total purchase price of $4,000,002. Upon the closing of this offering, each share of Series E Preferred Stock will be converted into two-thirds of a share of Common Stock. On November 18, 1993, in connection with the purchase of Common Stock upon exercise of stock options granted to R. Douglas Armstrong under the 1989 Stock Option Plan, the Company loaned to Dr. Armstrong $120,000 at an interest rate of 4% per annum pursuant to a full recourse promissory note. Interest on the note is payable on an annual basis and principal and accrued but unpaid interest is due on June 30, 1997. Dr. Armstrong is the President and Chief Executive Officer and is a director of the Company. On October 20, 1993, in connection with the purchase of Common Stock upon exercise of stock options granted to Stephen G. Emerson under the 1989 Stock Option Plan, the Company loaned to Dr. Emerson $47,303 at an interest rate of 6% per annum pursuant to a full recourse promissory note. Interest on the note is payable on an annual basis and principal and accrued but unpaid interest is due June 30, 1997. The loan is secured by 258,687 shares of Common Stock held by Dr. Emerson. Dr. Emerson is a director of the Company. In October 1996, the Company executed a financing commitment with Cobe to provide the Company with up to $5,000,000 (the "Equity Commitment") and up to $5,000,000 in funding from Michigan under a convertible loan commitment agreement ("Convertible Loan Commitment"). As of the date of this Prospectus, the Company has not obtained any financing under these commitments. Both the Equity Commitment and the Convertible Loan Commitment will terminate upon the consummation of this offering. 49 Under the terms of the Equity Commitment, the Company has an option to sell up to $5,000,000 of Series F Preferred Stock at a price of $6.00 per share to Cobe upon at least ninety days notice, which notice may be given at any time until September 1, 1997. Cobe's obligation to purchase such shares will terminate upon the closing of this offering. Although no shares of Series F Preferred Stock are outstanding, any outstanding shares of Series F Preferred Stock would convert upon the closing of this offering into Common Stock based upon a conversion price of 80% of the price of two-thirds of a share of Common Stock sold in this offering. To the extent shares are sold to Cobe under the Equity Commitment, Cobe's preemptive right in the Company's next financing and the Company's Put Option to Cobe would be reduced. Upon the sale of $5,000,000 of Series F Preferred Stock under the Equity Commitment, the Company becomes entitled to borrow funds from Michigan under the Convertible Loan Commitment. The Company may borrow such funds upon at least 45 days notice, which notice may be given during a period commencing on October 15, 1996 and ending on November 1, 1997. Upon the completion by the Company of a Qualifying Financing (as defined in the Convertible Loan Commitment), the Company has the option to repay outstanding principal and interest under the Convertible Loan Commitment in cash or to convert such borrowings into convertible Preferred Stock at a conversion price equivalent to 90% of the price per share in such financing. Under certain circumstances, the Convertible Loan Commitment converts or is convertible into Series G Preferred Stock. Interest accrues at an annual rate of 10% under the Convertible Loan Commitment, and the Company may repay such principal and interest at any time without penalty. The Company has issued warrants to Michigan to purchase 69,444 shares of Common Stock as consideration for securing the Convertible Loan Commitment and has agreed to issue additional warrants to purchase 8,333 shares of Common Stock for each $1,000,000 borrowed under the Convertible Loan Commitment, as adjusted to the level of borrowing. The warrants become exercisable 90 days after the closing of this offering. The warrants expire on October 15, 2000 if not exercised, and may be exercised, in whole or in part, at a price equal to the lesser of (a) $9.00 per share, which price increases by $3.00 per share upon each anniversary of the closing of the offering made hereby; and (b) 85% of the fair market value of the Company's Common Stock at the time of exercise. 50 PRINCIPAL STOCKHOLDERS The following table sets forth certain information regarding the beneficial ownership of the shares of the Company's Common Stock as of September 30, 1996, and as adjusted to give effect to the sale of 3,250,000 shares of Common Stock in this offering assuming (a) conversion of all of the Company's outstanding shares of Preferred Stock into Common Stock and (b) no exercise of the Underwriters' over-allotment option, and as adjusted to reflect the sale of shares offered in this offering, (i) by each person the Company knows to be the beneficial owner of 5% or more of the outstanding shares of Common Stock, (ii) each named executive officer listed in the Summary Compensation Table, (iii) each director of the Company, and (iv) all executive officers and directors of the Company as a group.

The Common Stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the Common Stock. All outstanding shares of Common Stock are fully paid and nonassessable. The rights, preferences and privileges of holders of Common Stock are subject to, and may be adversely affected by, the rights of the holders of any shares of any Preferred Stock which the Company may designate and issue in the future. PREFERRED STOCK As of the closing of the offering, no shares of Preferred Stock will be outstanding. Thereafter, the Board of Directors will be authorized, without further shareholder approval, to issue up to 5,000,000 shares of Preferred Stock in one or more series and to fix the rights, preferences, privileges and restrictions granted or imposed upon any unissued shares of Preferred Stock and to fix the number of shares constituting any series and the designations of such series. The issuance of Preferred Stock may have the effect of delaying or preventing a change in control of the Company. The issuance of Preferred Stock could decrease the amount of earnings and assets available for distribution to the holders of Common Stock or could adversely affect the rights and powers, including voting rights, of the holders of the Common Stock. In certain circumstances, such issuance could have the effect of decreasing the market price of the Common Stock. The Company currently has no plans to issue any shares of Preferred Stock. MICHIGAN LAW AND CERTAIN CHARTER PROVISIONS The Company is a Michigan corporation and is subject to certain anti- takeover provisions of the Michigan Business Corporation Act (the "MBCA") which could delay or make more difficult a merger or tender offer involving the Company. Chapter 7A of the MBCA prevents, in general, an "interested shareholder" (defined generally as a person owning 10% or more of a corporation's outstanding voting shares) from engaging in a "business combination" (as defined therein) with a Michigan corporation unless: (a) the Board of Directors issues an advisory statement, holders of 90% of the shares of each class of stock entitled to vote approve the transaction, and holders of two-thirds of the "disinterested" shares of each class of stock approve the transaction; or (b) the interested shareholder has been an interested shareholder for at least five years and has not acquired beneficial ownership of any additional shares of the corporation subsequent to the transaction which resulted in such shareholder being classified as an interested shareholder, and meets certain requirements, including, but not limited to, provisions relating to the fairness of the price and the form of consideration paid; or (c) the Board of Directors, by resolution, exempts a particular interested shareholder from these provisions prior to the interested 53 shareholder becoming an interested shareholder. The MBCA also contains certain other provisions which could have anti-takeover effects, including, but not limited to, Section 368, which pertains to "greenmail." The Company's Bylaws provide that the Board of Directors is divided into three classes of directors, with each class serving a staggered three-year term. The classification system of electing directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of the Company and may maintain the incumbency of the Board of Directors, as it generally makes it more difficult for shareholders to replace a majority of the directors. The Company's Restated Articles of Incorporation eliminate the right of shareholders to act without a meeting and do not provide for cumulative voting in the election of directors. The amendment of any of these provisions would require approval by holders of at least two- thirds of the shares of outstanding Common Stock. The foregoing and other statutory provisions and provisions of the Company's Restated Articles of Incorporation could have the effect of deterring certain takeovers or delaying or preventing certain changes in control or management of the Company, including transactions in which shareholders might otherwise receive a premium for their shares over then-current market prices. REGISTRATION RIGHTS Pursuant to the Amended and Restated Investors Rights Agreement, dated as of April 7, 1992, as amended (the "Investors Agreement"), certain holders of outstanding shares of Common Stock, including shares of Common Stock issuable upon conversion of the Preferred Stock (the "Registrable Securities"), are entitled to certain demand and incidental registration rights with respect to such shares, subject to certain customary limitations. Under the Investors Agreement, subject to certain exceptions, the holders of at least 50% of the Registrable Securities may require the Company to use its diligent best efforts to register Registrable Securities for public resale on one occasion (so long as such registration includes at least 20% of the Registrable Securities or a lesser percentage if the anticipated aggregate offering price net of underwriting discounts and commissions would exceed $2 million). In addition, whenever the Company proposes to register any of its securities under the Act, holders of Registrable Securities are entitled, subject to certain restrictions (including customary underwriters "cut back" limitations), to include their Registrable Securities in such registration. Subject to certain limitations, the holders of Registrable Securities may also require the Company to register such shares on Form S-3 no more than once every twelve months, provided that the anticipated aggregate proceeds would exceed $500,000. The Company is required to bear all registration and selling expenses (other than underwriter's discounts and commissions and more than a single special counsel to the selling shareholders) in connection with the registration of Registrable Securities in one demand registration and two piggy-back registrations. The participating investors are required to bear all expenses in connection with the registration of Registrable Securities on Form S-3. Registration rights may be transferred to an assignee or transferee provided that such assignee or transferee acquires at least 66,667 shares of the Registrable Securities held by the transferring holder (13,333 shares in the case of a transfer from the holder of certain stock options). These registration rights may be amended or waived (either generally or in a particular instance) only with the written consent of the Company and the holders of a majority of the Registrable Securities then outstanding. The registration rights granted under the Investors Agreement shall not be exercisable by a holder during the period in which the holder may sell all of the holder's shares under Rule 144 or Rule 144A during a single 90-day period. Pursuant to the Stock Purchase Agreement between the Company and Cobe, dated October 22, 1993 (the "Cobe Stock Agreement"), the Company granted to Cobe certain stock registration rights for any and all of the Company's Common Stock which Cobe acquires by conversion or otherwise. Cobe's stock registration rights commence 30 months following an initial public offering, or earlier in the event of any termination of the Distribution Agreement. Pursuant to Cobe's registration rights, Cobe is entitled to two demand registration rights, and an unlimited number of piggyback registration rights. Cobe's stock registration rights are subject to 54 customary underwriter's "cut back" requirements. The registration rights granted to Cobe shall not be exercisable during the period in which Cobe has the ability to sell all of its shares pursuant to Rule 144 during a single ninety-day period. Subject to certain conditions, these registration rights may be transferred with the transfer of stock to certain affiliates of the transferor or to a transferee who acquires the greater of 66,667 shares or 20% of the transferor's registrable stock. RIGHTS OF COBE Pursuant to the Cobe Stock Agreement, Cobe purchased an aggregate of $10,000,000 of shares of the Company's Series C Preferred Stock. Such shares of Series C Preferred Stock will automatically convert into 1,666,666 shares of Common Stock upon consummation of the offering. Pursuant to the Cobe Stock Agreement, Cobe also has certain preemptive rights to purchase a portion of any new stock issued by the Company, subject to certain exceptions, so as to enable Cobe to maintain its relative percentage ownership and voting power interests in the Company. Under the terms of the Cobe Stock Agreement, the Company also has the right to require Cobe to purchase stock issued by the Company in certain qualifying offerings, under certain circumstances (the "Put Option"). The Put Option may generally require Cobe to purchase up to 25% of the stock issued by the Company in a qualifying offering upon the same terms and conditions as the underwriters or other purchasers participating in the offering provided that Cobe shall not be required to purchase stock having an aggregate purchase price of more than $5 million. If the Company exercises its Put Option with respect to any such qualifying offering, Cobe has the option to purchase the greater of up to 40% of the number of shares to be offered in the qualifying offering or the number of shares necessary to maintain its percentage ownership interest in the Company. Additionally, for a three-year period following the Company's completion of its initial public offering of stock, Cobe will have an option to purchase from the Company a quantity of new shares of the Company's Common Stock at a price equal to 120% of the public market trading price for the Company's Common Stock. The quantity of Common Stock to be purchased if Cobe exercises this option shall be equal to 30% of the Company's fully diluted shares after the exercise of this option. In the Cobe Stock Agreement, the Company also granted to Cobe a "right of first negotiation" in the event the Company receives any proposal concerning, or otherwise decides to pursue, a merger, consolidation or other transaction in which all or a majority of the Company's equity securities or all or substantially all of the Company's assets, or any material portion of the assets of the Company used by the Company in performing its obligations under the Distribution Agreement would be acquired by a third party outside of the ordinary course of business. Pursuant to the Stock Purchase Commitment Agreement with Cobe, dated October 29, 1996, the Company agreed to use reasonable and good faith efforts to cause a nominee of Cobe, who must be deemed by the Board of Directors to be qualified to be elected to the Board of Directors for as long as Cobe owns at least 15% of the outstanding Common Stock. 55 SHARES ELIGIBLE FOR FUTURE SALE Upon completion of this offering, the Company will have 13,235,734 shares of Common Stock outstanding, assuming no exercise of any outstanding options under any of the Company's option plans after September 30, 1996. Of these shares, the 3,250,000 shares of Common Stock sold in this offering will be freely transferable without restriction under the Securities Act unless they are held by the Company's affiliates as that term is used in Rule 144 under the Securities Act. The remaining 9,985,734 shares (the "Restricted Shares") were issued and sold by the Company in private transactions in reliance upon exemptions from registration contained in the Act. A total of 6,873 Restricted Shares held for more than three years by shareholders who are not affiliates of the Company and who are not subject to the lock-up agreements described below will be eligible for sale in the public market in reliance upon Rule 144(k) immediately following the commencement of this offering. A total of 8,735,744 additional outstanding shares will be eligible for sale in the public market commencing 180 days from the date of this Prospectus without restriction, other than volume limitations in certain instances, upon the expiration of certain lock-up agreements referred to below. As of the date 90 days after the date of this Prospectus, 31,014 additional shares will be available for sale pursuant to Rule 144 or 701 under the Act, and 1,212,103 Restricted Shares will have been held for less than two years and will not be eligible for sale in the market until they have met the two-year holding period requirements of Rule 144. The executive officers and directors of the Company, and certain other stockholders and optionholders of the Company, have executed 180-day lock-up agreements. Cowen & Company may release some or all of the shares subject to lock-up agreements at any time without notice. In general, under Rule 144, a person (or persons whose shares are aggregated), stockholders, including an affiliate, who has beneficially owned shares for at least two years is entitled to sell in broker transactions, within any three-month period, commencing 90 days after this offering, a number of shares that does not exceed the greater of (i) 1% of the then outstanding Common Stock (approximately 132,357 shares immediately after this offering assuming no exercise of the Underwriters' over-allotment option) or (ii) the average weekly trading volume in the Common Stock during the four calendar weeks preceding the sale, subject to the filing of a Form 144 with respect to the sale and other limitations. In general, shares issued in compliance with Rule 701 may be sold by non-affiliates subject to the manner of sale requirements of Rule 144, but without compliance with the other requirements of Rule 144. Affiliates may sell shares they acquired under Rule 701 in compliance with the provisions of Rule 144, except that there is no required holding period. A person who is not an affiliate, has not been an affiliate within three months prior to sale and has beneficially owned the Restricted Shares for at least three years, is entitled to sell such shares under Rule 144 without regard to any of the limitations described above. The Company intends to file a registration statement under the Securities Act to register Common Stock reserved for issuance under its 1992 Plan, Directors Plan and Purchase Plan. Such registration statement is expected to become effective approximately 90 days after the date of this Prospectus. Shares issued upon exercise of outstanding stock options under such plan after the effective date of such registration statement generally will be available for sale in the public market. As of September 30, 1996, options to purchase a total of 336,254 shares of Common Stock were outstanding and 1,100,906 options remained available for grant under the 1992 Plan. No options have been granted under the Directors Plan. The Company has also agreed not to offer, sell, contract to sell or otherwise dispose of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or any rights to acquire Common Stock for a period of 180 days after the date of this Prospectus, without the prior written consent of the Underwriters, subject to certain limited exceptions (including exercises of stock options). Prior to this offering, there has been no public market for the Common Stock of the Company. No prediction can be made regarding the effect, if any, that the sale or availability for sale of shares of additional Common Stock will have on the market price of the Common Stock. Nevertheless, sales of substantial numbers of shares by existing stockholders or by stockholders purchasing in their offering could have a negative effect on the market price of the Common Stock. 56 UNDERWRITING Subject to the terms and conditions of the Underwriting Agreement, the Underwriters named below (the "Underwriters"), through their Representatives, Cowen & Company and J.P. Morgan Securities Inc., have severally agreed to purchase from the Company the following respective number of shares of Common Stock at the initial public offering price less the underwriting discounts and commissions set forth on the cover page of this Prospectus:
NUMBER OF SHARES OF UNDERWRITER COMMON STOCK ----------- ------------ Cowen & Company................................................ J.P. Morgan Securities Inc..................................... --------- Total........................................................ 3,250,000 =========
The Underwriting Agreement provides that the obligations of the Underwriters are subject to certain conditions precedent and that the Underwriters will purchase all of the Common Stock offered hereby if any of such shares are purchased. The Company has been advised by the Representatives of the Underwriters that the Underwriters propose to offer the shares of Common Stock to the public at the initial public offering price set forth on the cover page of this Prospectus and to certain dealers at such price less a concession not in excess of $ per share. The Underwriters may allow, and such dealers may reallot, a concession not in excess of $ per share to certain other dealers. After the initial public offering, the offering price and other selling terms may be changed by the Representatives of the Underwriters. The Company has granted to the Underwriters an option, exercisable not later than 30 days after the date of this Prospectus, to purchase up to 487,500 additional shares of Common Stock at the initial public offering price less the underwriting discounts and commissions set forth on the cover page of this Prospectus. To the extent that the Underwriters exercise such option, each of the Underwriters will have a firm commitment to purchase approximately the same percentage thereof that the number of shares of Common Stock to be purchased by it shown in the above table bears to 3,250,000, and the Company will be obligated, pursuant to the option, to sell such shares to the Underwriters. The Underwriters may exercise such option only to cover over- allotments made in connection with the sale of the Common Stock offered hereby. If purchased, the Underwriters will offer such additional shares on the same terms as those on which the 3,250,000 shares are being offered. The Company has agreed to indemnify the several Underwriters against certain liabilities, including liabilities under the Securities Act. The Company and its directors and officers, and certain of its other stockholders and optionholders, have entered into agreements providing that, for a period of 180 days after the date of this Prospectus, they will not, without the prior written consent of Cowen & Company, offer, sell, contract to sell or otherwise dispose of any shares of Common Stock or any securities convertible into, or exchangeable for, or warrants to purchase, any shares of Common Stock, or grant any option to purchase or right to acquire or acquire any option to dispose of any shares of Common Stock, except in certain limited circumstances. See "Shares Eligible for Future Sale." The Representatives of the Underwriters have advised the Company that the Underwriters do not intend to confirm sales to any account over which they exercise discretionary authority. 57 Prior to this offering, there has been no public market for the Common Stock of the Company. Consequently, the initial public offering price for the Common Stock has been determined by negotiations between the Company and the Representatives of the Underwriters. Among the factors considered in such negotiations were prevailing market conditions, the results of operations of the Company in recent periods, the market capitalizations and stages of development of other companies that the Company and the Representatives of the Underwriters believe to be comparable to the Company, estimates of the business potential of the Company, the present state of the Company's development, and other factors deemed relevant.

F-1 REPORT OF INDEPENDENT ACCOUNTANTS To the Board of Directors of Aastrom Biosciences, Inc.: We have audited the accompanying balance sheets of Aastrom Biosciences, Inc. (a Michigan corporation in the development stage) as of June 30, 1995 and 1996, and the related statements of operations, stockholders' equity, and cash flows for the years ended June 30, 1994, 1995 and 1996, and the cumulative period from March 24, 1989 (inception) to June 30, 1996. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Aastrom Biosciences, Inc. as of June 30, 1995 and 1996, and the results of its operations and its cash flows for the years ended June 30, 1994, 1995 and 1996, and the cumulative period from March 24, 1989 (inception) to June 30, 1996, in conformity with generally accepted accounting principles. Detroit, Michigan August 9, 1996 To the Board of Directors of Aastrom Biosciences, Inc.: The financial statements herein have been adjusted to give effect to the 2 for 3 reverse stock split of the Company's outstanding Common Shares as described more fully in Note 1 to the financial statements. The above report is in the form that will be signed by Coopers & Lybrand L.L.P. upon the effectiveness of such split assuming that, from October 31, 1996 to the effective date of such split, no other events shall have occurred that would affect the accompanying financial statements or notes thereto.

The accompanying notes are an integral part of these financial statements. F-6 AASTROM BIOSCIENCES, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS (INFORMATION AS OF SEPTEMBER 30, 1996 AND FOR THE THREE-MONTH PERIODS ENDED SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED) 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Overview--Aastrom Biosciences, Inc. (the "Company") was incorporated in March 1989 ("Inception") under the name Ann Arbor Stromal, Inc. The Company changed its name in 1991 concurrent with the commencement of employee-based operations. The Company is in the development stage with its principal business activities being research and product development, conducted both on its own behalf and in connection with various collaborative research and development agreements with other companies, involving the development of processes and instrumentation for the ex-vivo production of human stem cells and their progeny, and hematopoetic and other tissues. Successful future operations are subject to several technical and business risks, including satisfactory product development and obtaining regulatory approval and market acceptance for its products. Significant Revenue Relationships--Two companies accounted for 77% of total revenues for the year ended June 30, 1995 and one company accounted for 83% of total revenues for the year ended June 30, 1996. These two companies have accounted for 47% of total revenues for the period from Inception to June 30, 1996. One company accounted for 82% and 87% of total revenues for the three months ended September 30, 1995 and 1996, respectively, and two companies accounted for 49% of total revenues for the period from Inception to September 30, 1996. Grant revenues consist of grants sponsored by the U.S. government. Cash and Cash Equivalents--Cash and cash equivalents include cash and short- term investments with original maturities of three months or less. Short-Term Investments--Short-term investments consist of U.S. government securities and commercial paper with original maturities of over three months but less than one year. Short-term investments are classified as available- for-sale, and are carried at market value, in accordance with Financial Accounting Standards Board Statement No. 115, "Accounting for Certain Investments in Debt and Equity Securities," which was adopted July 1, 1994. Application of this pronouncement results in the inclusion of unrealized gains and losses on investments in stockholders' equity. Application of this accounting treatment in prior periods would not have materially changed the amounts as presented. Diversity of Credit Risk--The Company invests its excess cash in U.S. government securities and commercial paper, maintained in U.S. financial institutions, and has established guidelines relative to diversification and maturities in an effort to maintain safety and liquidity. The Company plans to continue to invest its excess funds in short-term, investment grade, interest- bearing instruments. These guidelines are periodically reviewed and modified to take advantage of trends in yields and interest rates. The Company has not experienced any significant losses on its cash equivalents or short-term investments. Property--Property is recorded at cost and depreciated or amortized using the straight-line method over the estimated useful life of the asset (primarily five years) or the remaining lease term, if shorter, with respect to leasehold improvements and certain capital lease assets. Revenue Recognition--Revenue from grants and research agreements is recognized on a cost reimbursement basis consistent with the performance requirements of the related agreement. Funding received in advance of costs incurred is presented as deferred revenue in the accompanying financial statements. Research and Development Costs--Research and development costs are expensed as incurred. Such costs and expenses related to programs under collaborative agreements with other companies totaled $49,000, $146,000 and $1,294,000 for the years ended June 30, 1994, 1995 and 1996, respectively, and $1,489,000 for the period from Inception to June 30, 1996 and $158,000, $117,000 and $1,606,000 for the three months ended September 30, 1995 and 1996 and for the period from Inception to September 30, 1996, respectively. F-7 AASTROM BIOSCIENCES, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) (INFORMATION AS OF SEPTEMBER 30, 1996 AND FOR THE THREE-MONTH PERIODS ENDED SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED) Restatement of Common Stock Information--The Company's Board of Directors authorized a two-for-three reverse stock split of the Company's Common Stock ("Reverse Stock Split") to be effected prior to the closing of the proposed IPO. Accordingly, all references in the accompanying financial statements to common share or per common share information have been restated to reflect the Reverse Stock Split. Pro Forma Information (Unaudited)--Pro forma net loss per share is computed using the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares are not included in the per-share calculation where the effect of their inclusion would be anti- dilutive, except that common and common equivalent shares issued during the 12 month period preceding the filing of the registration statement for the proposed initial public offering ("IPO"), contemplated in the Prospectus in which these financial statements are included, at a price below $8.00 per share (the lowest expected selling price in the proposed IPO) are considered to be cheap stock and have been included in the calculation as if they were outstanding for all periods using the treasury stock method, if applicable, even though their inclusion is anti-dilutive. Upon the completion of the Company's proposed IPO, all 9,657,648 shares of the Company's outstanding Preferred Stock will automatically convert into 8,098,422 shares of Common Stock. As a result, all outstanding shares of Preferred Stock are assumed to have been converted to Common Stock at the time of issuance, except for those shares considered to be cheap stock which are treated as outstanding for all periods presented. The pro forma effect of these conversions has been reflected in the accompanying balance sheet assuming the conversion had occurred on September 30, 1996. Historical net loss per share information is not considered meaningful due to the significant changes in the Company's capital structure which will occur upon the closing of the proposed IPO; accordingly, such per-share data information is not presented. Use of Estimates--The preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates that affect the amounts reported in the financial statements and disclosures made in the accompanying notes to financial statements. Actual results could differ from those estimates. Financial Instruments--Management evaluates the fair value of those assets and liabilities identified as financial instruments under Statement of Financial Accounting Standards No. 107 and estimates that the fair value of such financial instruments generally approximates the carrying value in the accompanying financial statements. Fair values have been determined through information obtained from market sources and management estimates. Recent Pronouncements--During October 1995, the Financial Accounting Standards Board issued Statement No. 123, "Accounting for Stock-Based Compensation," which establishes a fair value based method of accounting for stock-based compensation and incentive plans and requires additional disclosures for those companies that elect not to adopt the new method of accounting. Adoption of this pronouncement is required for the Company's fiscal year beginning July 1, 1996 and the Company intends to provide the additional disclosures required by the pronouncement in its financial statements for the year ended June 30, 1997. During March 1995, the Financial Accounting Standards Board issued Statement No. 121 (SFAS 121), "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," which requires the Company to review for impairment of long-lived assets, certain identifiable intangibles, and goodwill related to those assets whenever events or changes in circumstances indicate that the carrying amount of an asset F-8 AASTROM BIOSCIENCES, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) (INFORMATION AS OF SEPTEMBER 30, 1996 AND FOR THE THREE-MONTH PERIODS ENDED SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED) might not be recoverable. In certain situations, an impairment loss would be recognized. SFAS 121 will become effective for the Company's fiscal year beginning July 1, 1996. Management has studied the effect of implementing SFAS 121 and, based upon its initial evaluation, does not expect it to have a significant impact on the Company's financial condition or results of operations. Unaudited Financial Information--The financial information as of September 30, 1996, and for the three-month periods ended September 30, 1995 and 1996, and for the period from Inception to September 30, 1996, is unaudited. In the opinion of management, such information contains all adjustments, consisting only of normal recurring accruals, necessary for a fair statement of the results of operations for the interim periods. The results of operations for the three months ended September 30, 1996, are not necessarily indicative of the results to be expected for the full year. 2. SHORT-TERM INVESTMENTS All short-term investments are available-for-sale, and have maturities of one year or less and are summarized as follows:

All preferred shares have voting rights equal to the equivalent number of common shares into which they are convertible. Conversion rights on all outstanding classes of preferred stock are on a two-for-three basis to give effect for the Reverse Stock Split, except for the Series C Preferred Stock, each share of which is convertible into approximately 250 shares of Common Stock. Conversion rights on certain classes of preferred stock are subject to anti-dilution adjustments. Dividends accrue annually at 8% on all series of Preferred Stock, but do not accumulate. No cash dividends have been declared or paid through September 30, 1996. Dividends and liquidation preferences on the Series B, Series C and Series D Preferred Stock are senior to those of the Series A Preferred Stock. Dividends and liquidation preferences on the Series E Preferred Stock are senior to those of all other outstanding series of preferred stock. Conversion of preferred stock is automatic in the event of the closing of an underwritten public stock offering meeting certain minimum requirements such as the offering contemplated by the Prospectus in which these financial statements are included. Cobe Laboratories, Inc. Stock Purchase Rights--In connection with the purchase of the Series C Preferred Stock by Cobe Laboratories, Inc. ("Cobe") in October 1993, Cobe received a preemptive right to purchase a pro-rata portion of any newly issued shares of stock by the Company in order to maintain its then current percentage ownership interest. Any such purchase of newly issued shares shall be at the net price to the Company after deducting underwriters' discounts and commissions, if any. Cobe has waived its right to such discount on its intended purchase of shares in the proposed IPO. The Company has an option ("Put Option") to require Cobe to purchase the lesser of 20%, or $5,000,000, in an offering of equity securities meeting certain minimum requirements. In the event that the Company exercises the Put Option, Cobe then has the option to purchase up to 40% of that offering. During the three-year period following the completion of an initial public offering of Common Stock by the Company, Cobe has an option to purchase additional shares from the Company equal to 30% of the total number of shares outstanding assuming exercise of the option. Such option, if exercised, must be exercised in full with the purchase price of the shares being established at 120% of the public market trading price as determined by the 30-day average market price preceding the date of exercise of the option. The Company has granted Cobe a right of first negotiation in the event the Company receives any proposal concerning, or otherwise decides to pursue, a merger, consolidation or other transaction in which all or a majority F-10 AASTROM BIOSCIENCES, INC.

Stock Option Plans--The Company has various stock option plans which provide for the issuance of nonqualified and incentive stock options to acquire up to 2,836,594 shares of Common Stock. Such options may be granted by the Company's Board of Directors to certain of the Company's founders, employees, directors and consultants. The exercise price of incentive stock options shall not be less than the fair market value of the shares on the date of grant. In the case of individuals who are also holders of 10% or more of the outstanding shares of Common Stock, the exercise price of incentive stock options shall not be less than 110% of the fair market value of the shares on the date of grant. The exercise price of non-qualified stock options shall not be less than 85% of the fair market value on the date of grant. Options granted under these plans expire no later than ten years from the date of grant and generally become exercisable ratably over a four-year period following the date of grant. For certain options granted, the Company recognizes compensation expense for the difference between the deemed value for accounting purposes and the option exercise price on the date of grant. During the three-month period ended September 30, 1996, compensation expense totaling approximately $40,000 has been charged with respect to these options. Additional future compensation expense with respect to the issuance of such options totals approximately $130,000 and will be recognized through October 2000. F-11 AASTROM BIOSCIENCES, INC.

Due to the historical losses incurred by the Company, a full valuation allowance for deferred tax assets has been provided. If the Company achieves profitability, these deferred tax assets may be available to offset income taxes. The Company's net operating loss and tax credit carryforwards will expire from 2004 through 2011, if not utilized. The Company's ability to utilize its net operating loss and tax credit carryforwards would be limited in the event of a future change in ownership for tax purposes. Such a change in ownership may likely occur upon the completion of an initial public offering of the Company's Common Stock. 6. LICENSES, ROYALTIES AND COLLABORATIVE AGREEMENTS University of Michigan--In March 1989, the Company entered into a research agreement with the University of Michigan (the "University") for the development of an adaptable, high-efficiency blood cell factory and to conduct related research. Under the terms of this research agreement, as amended, the Company agreed to reimburse the University for research costs in this regard through the date of its expiration in December 1994. Payments made to the University under the aforementioned agreements totaled $316,000, $121,000 and $2,521,000 for the years ended June 30, 1994, 1995, for the period from Inception to June 30, 1996. As part of this relationship, the Company issued to the University 454,545 shares of Common Stock in August 1989. No value has been assigned to these shares in the accompanying financial statements. In March 1992, the Company entered into a license agreement for the technology developed under the research agreement. The license agreement, as amended, provides for a royalty to be paid to the University equal to 2% of net sales of products containing the licensed technology sold by the Company. Cobe BCT, Inc.--In connection with the issuance of the Series C Preferred Stock to Cobe in October 1993, the Company and Cobe BCT, Inc. ("Cobe BCT"), an affiliate of Cobe, entered into an agreement which grants to Cobe BCT exclusive worldwide distribution and marketing rights to the Company's Cell Production System ("CPS") for stem cell therapy applications ("Distribution Agreement"). The term of the Distribution Agreement is ten years, with an option, exercisable by Cobe BCT, to extend the term for an additional ten years. Pursuant to the Distribution Agreement, Cobe BCT will perform worldwide marketing and distribution activities of the CPS for use in stem cell therapy and will receive a share of the resulting net sales, as defined, ranging from 38% to 42%, subject to certain negotiated discounts and volume-based adjustments. F-13 AASTROM BIOSCIENCES, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) (INFORMATION AS OF SEPTEMBER 30, 1996 AND FOR THE THREE-MONTH PERIODS ENDED SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED) The agreements establishing this collaboration provided for payments totaling $5,000,000 to be made by Cobe BCT upon the Company meeting certain development milestones. In May 1995, the Company accepted, as part of the sale of the Series D Preferred Stock, an equity investment of $5,000,000 from Cobe in lieu of those future milestone payments. M.D. Anderson Cancer Center--In December 1992, the Company entered into a research agreement with the University of Texas, M.D. Anderson Cancer Center ("M.D. Anderson"). Under this agreement, the Company funded certain research being conducted at M.D. Anderson and issued to M.D. Anderson 33,333 shares of its Common Stock subject to vesting rights over the succeeding four year period. In November 1994, the Company and M.D. Anderson terminated the collaboration and 25,000 shares of Common Stock held by M.D. Anderson were returned to the Company. License and Royalty Agreements--In July 1992, the Company licensed certain cell culture technology under which it obtained an exclusive worldwide license to the technology in exchange for a royalty of up to 3% of net sales on products utilizing the licensed technology. In March 1996, the Company executed a license agreement which provides for the use of licensed products in the CPS. Pursuant to this license agreement, the Company recorded a charge to research and development expense of $1,500,000 representing the license fee payable upon execution of the agreement. The license agreement provides for annual renewal fees of $1,000,000 over the five year license term and can be extended at the Company's option for an additional five years. Rhone-Poulenc Rorer Inc.--In September 1995, the Company entered into a research and development collaboration with Rhone-Poulenc Rorer Inc. ("RPR"), granting RPR a right to license the Company's CPS for Lymphoid cell applications. Prior to the establishment of this collaboration, the Company received a option fee of $250,000 and a development deposit of $225,000 to initiate the preliminary research and development plan. Pursuant to the agreements establishing this collaboration, RPR was obligated to fund certain costs associated with the development of the CPS for Lymphoid cell applications and was entitled to make equity purchases of up to $12,500,000 subject to the Company's satisfaction of certain milestones and RPR's decision to exercise certain options. As of June 30, 1996, the Company has received $3,500,000 in equity payments and recognized $1,342,000 in research revenue through June 30, 1996 and $1,537,000 through September 30, 1996. The remaining $9,000,000 equity payment was to be paid by RPR by October 1996 pending RPR's evaluation of the research efforts for Lymphoid cell applications and its decision to proceed with the collaboration (Note 9). 7. COMMITMENTS The Company leases certain machinery and equipment and office equipment under capital leases. Obligations under these leasing arrangements bear interest at rates ranging from 9.7% to 12.1% and mature at dates ranging from November 1996 to May 1999. Additionally, the Company leases its facilities under an operating lease which expires in May 1998, at which time the Company has the option to renew the lease for an additional period of up to five years. F-14 AASTROM BIOSCIENCES, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) (INFORMATION AS OF SEPTEMBER 30, 1996 AND FOR THE THREE-MONTH PERIODS ENDED SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED) Future minimum payments under capital leases and non-cancelable operating leases are as follows:
CAPITAL OPERATING LEASES LEASES -------- --------- Year Ended June 30, 1997................................................ $255,000 $453,000 1998................................................ 138,000 435,000 1999................................................ 69,000 -- -------- -------- Total minimum lease payments.......................... 462,000 $888,000 ======== Less amount representing interest..................... (50,000) -------- Obligations under capital lease....................... $412,000 ========
Certain of the Company's capital lease agreements contain restrictive provisions which require that the Company's total assets exceed its total liabilities by at least $1,000,000. Should the Company fall out of compliance with this provision, and a waiver cannot be obtained from the lessor, remaining amounts due under the leases become immediately due and payable. Rent expense for the years ended June 30, 1994, 1995 and 1996, was $176,000, $241,000 and $338,000, respectively, and for the period from Inception to June 30, 1996 was $822,000. Rent expense for the three months ended September 30, 1995 and 1996, was $83,000 and $107,000, respectively, and for the period from Inception to September 30, 1996 was $929,000. 8. EMPLOYEE SAVINGS PLAN The Company has a 401(k) plan that became effective in January 1994. The plan allows participating employees to contribute up to 15% of their salary, subject to annual limits and minimum qualifications. The Board may, at its sole discretion, approve Company contributions. Through June 30, 1996, the Company has made no contributions to the plan. 9. SUBSEQUENT EVENTS (UNAUDITED) In September 1996, RPR notified the Company of its intent to terminate its collaboration with the Company. This notification was made after RPR had determined that for strategic reasons its support for the development of the technologies being pursued under the collaboration would be discontinued. As a result of this termination, no further equity payments or research funding is due from RPR and RPR's license rights to the Company's CPS for Lymphoid cell applications are terminated. Upon termination of the collaboration, RPR became entitled to receive shares of the Company's Series E Preferred Stock at $17.00 per share for the $3,500,000 in equity payments made by RPR under the collaboration. Accordingly, the accompanying financial statements as of September 30, 1996 reflect the issuance of 205,882 shares of Series E Preferred Stock issuable to RPR in this regard. In October 1996, the Company executed a financing commitment for up to $5,000,000 in additional equity funding from Cobe ("Equity Commitment") and $5,000,000 in funding under a convertible loan agreement ("Convertible Loan Commitment") with another current investor. Under the terms of the Equity Commitment, F-15 AASTROM BIOSCIENCES, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) (INFORMATION AS OF SEPTEMBER 30, 1996 AND FOR THE THREE-MONTH PERIODS ENDED SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED) the Company may sell up to $5,000,000 of preferred stock at $6.00 per share during a funding period that extends from January 1997 to December 1997. The conversion rights of such preferred stock will be adjusted to provide for a conversion at 80% of the per share price in the Company's next financing, as adjusted for the Reverse Stock Split, and provided that such financing meets certain minimum requirements ("Qualifying Financing"), such as the proposed IPO in which these financial statements appear. If such a financing is not completed by December 1997, then the conversion rights of this class of preferred stock into Common Stock will be set at $6.98 per share of Common Stock. To the extent shares are sold to Cobe under the Equity Commitment, its preemptive right in the Company's next Qualifying Financing and the Company's Put Option to Cobe is reduced to the extent of its purchase. Upon the sale of $5,000,000 in preferred stock under the Equity Commitment, the Company becomes entitled to borrow funds under the Convertible Loan Commitment. Such funds may be borrowed by the Company during a funding period that extends from January 1997 to September 1997. Upon the completion of a Qualifying Financing by the Company, the Company has the option to repay outstanding borrowings under the Convertible Loan Commitment, in cash, or to convert such borrowings into preferred stock. The conversion rights of such class of preferred stock will be adjusted to provide for a conversion at 90% of the per share price in the Company's next Qualifying Financing, as adjusted for the Reverse Stock Split. If such financing is not completed by December 1997, then the conversion rights of this class of preferred stock will be set at $6.98 per share of Common Stock. Interest accrues at 10% on amounts borrowed under the Convertible Loan Commitment, which is due at maturity, and may be retired in a manner consistent with principal. The Company may repay borrowed amounts at anytime prior to the maturity date which is established for all amounts borrowed as one year from the date of the first borrowing. In connection with the Convertible Loan Commitment, the Company has issued warrants to purchase 69,444 shares of Common Stock for securing the commitment. The Company will issue additional warrants to purchase 8,333 shares of Common Stock for each $1,000,000 borrowed under the Convertible Loan Commitment, with such additional warrants to be prorated to the level of borrowing. The warrants expire on October 15, 2000 if not exercised, and may be exercised, in whole or in part, at a price equal to the lesser of (a) $9.00 per share, which price increases by $3.00 per share on each anniversary of the closing of the offering being made in the Prospectus to which these financial statements are included; or (b) 85% of the fair market value of the Company's Common Stock at the time of exercise. The Equity Commitment and the Convertible Loan Commitment expire upon the closing of an initial public offering by the Company.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS Sections 1561 through 1565 of the Michigan Business Corporation Act (the "MBCA") authorize a corporation to grant or a court to award, indemnity to directors, officers, employees and agents in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act of 1933. The Bylaws of the Company (see Exhibit 3.4), provide that the Company shall, to the fullest extent authorized or permitted by the MBCA, or other applicable law, indemnify a director or officer who was or is a party or is threatened to be made a party to any proceeding by or in the right of the Company to procure a judgment in its favor by reason of the fact that such person is or was a director, officer, employee or agent of the Company, against expenses, including actual and reasonable attorneys' fees, and amounts paid in settlement incurred in connection with the action or suit, if the indemnitee acted in good faith and in a manner the person reasonably believed to be in, or not opposed to, the best interests of the Company or its shareholders. This section also authorizes the Company to advance expenses incurred by any agent of the Company in defending any proceeding prior to the final disposition of such proceeding upon receipt of an undertaking by or on behalf of the agent to repay such amount unless it shall be determined ultimately that the agent is entitled to be indemnified. The Bylaws also authorize the Company to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Company against any liability asserted against or incurred by such person in such capacity or arising out of such person's status as such, regardless of whether the Company would have the power to indemnify such person against such liability under the provisions of the MBCA. The Company has entered into an indemnification agreement with certain of its directors, officers and other key personnel, which contains provisions that may in some respects be broader than the specific indemnification provisions contained under applicable law. The indemnification agreement may require the Company, among other things, to indemnify such directors, officers and key personnel against certain liabilities that may arise by reason of their status or service as directors, officers or employees of the Company, to advance the expenses incurred by such parties as a result of any threatened claims or proceedings brought against them as to which II-1 they could be indemnified, and, to the maximum extent that insurance coverage of such directors, officers and key employees under the Company's directors' and officers' liability insurance policies is maintained. Section 1209 of the MBCA permits a Michigan corporation to include in its Articles of Incorporation a provision eliminating or limiting a director's liability to a corporation or its shareholders for monetary damages for breaches of fiduciary duty. The enabling statute provides, however, that liability for breaches of the duty of loyalty, acts or omissions not in good faith or involving intentional misconduct or knowing violation of the law, or the receipt of improper personal benefits cannot be eliminated or limited in this manner. The Company's Restated Articles of Incorporation include a provision which eliminates, to the fullest extent permitted by the MBCA director liability for monetary damages for breaches of fiduciary duty. Section 6 of the Underwriting Agreement filed as Exhibit 1.1 hereto sets forth certain provisions with respect to the indemnification of certain controlling persons, directors and officers against certain losses and liabilities, including certain liabilities under the Securities Act. ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES (a)ISSUANCES OF COMMON STOCK Since October 1, 1993, the Company has sold the following shares of Common Stock: In October 1995, the registrant issued 37,500 shares of Common Stock to Albert B. Deisseroth at a price of $.80 per share. (b) ISSUANCES OF SHARES OF PREFERRED STOCK Since October 1, 1993, the Company has sold the following shares of Preferred Stock: In October 1993, the registrant issued 10,000 shares of Series C Preferred Stock to Cobe at a price of $1,000 per share. In April and May 1995, the registrant issued an aggregate of 2,500,001 shares of Series D Preferred Stock to 11 accredited investors at a price of $4.00 per share. In December 1995, the registrant issued 62,500 shares of Series D Preferred Stock to Northwest Ohio Venture Fund, L.P. at a purchase price of $4.00 per share. In January 1996, the registrant issued an aggregate of 1,411,765 shares of Series E Preferred Stock to SBIC Partners, L.P. and the State Treasurer of the State of Michigan at a purchase price of $4.25 per share. Pursuant to a Governance Agreement between the Company and Rhone-Poulenc Rorer Inc. ("RPR"), dated September 15,1995, RPR terminated its contractual relationship with the Company on September 6, 1996. As a result of such termination, the Company became obligated to issue 205,882 shares of Series E Preferred Stock to RPR at a purchase price of $17.00 per share. The Company believes that each such sale and issuance of securities was exempt from registration pursuant to Section 4(2) of the Securities Act of 1933, as amended. (c) OPTION ISSUANCES TO, AND EXERCISES BY, EMPLOYEES AND DIRECTORS From January 18, 1990 to the present, the registrant has granted options to purchase a total of 2,945,174 shares of Common Stock at exercise prices ranging from $.10 to $2.13 per share to 95 employees and one non-employee director.

ITEM 17. UNDERTAKINGS The undersigned Registrant hereby undertakes to provide to the Underwriters at the closing specified in the Underwriting Agreement certificates in such denominations and registered in such names as required by the Underwriters to permit prompt delivery to each purchaser. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant, pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. The undersigned Registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part of this registration statement as of the time it was declared effective. (2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. II-5 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Ann Arbor, State of Michigan, on the 1st day of November, 1996.

    added to the records of the Corporation and Securities Bureau. The original

 3. This document is to be used pursuant to sections 641 through 643 of the Act
    for the purpose of restating the articles of incorporation of a domestic

    articles of incorporation, along with any desired amendments to those
    articles.

 4. Restated articles of incorporation which do not amend the articles of
    incorporation may be adopted by the board of directors without a vote of the

    incorporation require adoption by the shareholders. Restated articles of
    incorporation submitted before the first meeting of the board of directors
    require adoption by all of the incorporators.

 5. Item 2 - Enter the identification number previously assigned by the Bureau.

upon any voluntary or involuntary liquidation, dissolution or winding up of the
affairs of the Corporation shall be as set forth in Section 3 of Part B of this

     Section 3. Dividends. Dividends may be paid on the Common Stock as and when
declared by the Board of Directors, subject in all cases to Section 2 of Part B
of this Article III.

PART B:  PREFERRED STOCK

     Section 1.  Designation. The Preferred Stock shall consist of six series to
 be designated and known as "Series A Preferred Stock" (or "Series A"), "Series
 B Preferred Stock" (or "Series B"), "Series C Preferred Stock" (or "Series C"),
 "Series D Preferred Stock" (or "Series D"), "Series E Preferred Stock" (or
 "Series E") and "Series F Preferred Stock" (or "Series F"). All series of
 Preferred Stock shall be identical with each other in all respects except as
 otherwise provided herein. As used herein, the term "Preferred Stock" without
 designation shall refer to shares of Series A, Series B, Series C, Series D,
 Series E and Series F Preferred Stock, or to shares of any series. The number
 of shares constituting each such series of Preferred Stock shall be as set
 forth below:
          .     Series A Preferred Stock:   2,500,000 shares.
                                           
          .     Series B Preferred Stock:   3,030,000 shares.
                                           
          .     Series C Preferred Stock:   10,000 shares.
                                           
          .     Series D Preferred Stock:   3,000,000 shares.
                                         
          .     Series E Preferred Stock:   1,617,647 shares.

Board of Directors subject to the restrictions imposed by the Michigan Business
Corporation Act. Dividends on the Preferred Stock shall not be cumulative and 
no right to such dividends shall accrue to holders of Preferred Stock unless 
declared by the Board of Directors. Holders of outstanding shares of certain 
series of Preferred Stock 

         

 
shall be entitled to receive dividends in preference to any dividend (whether in
cash, securities of the Corporation or other property) on certain other shares
of capital stock of the Corporation, as set forth below in terms of four
"Levels," to be designated and known as "Level 1," "Level 2," "Level 3" and
"Level 4." No dividends or other distributions shall be made with respect to a
particular Level until all dividends on the preceding Levels have been paid on
or set apart for payment. For example, dividends on Level 3 shall not be paid or
set apart for payment until full dividends on Level 1 and Level 2 have been paid
or set apart for payment. Dividends, if paid, must be paid on, or, if declared
and set apart for payment on, must be declared and set apart for payment on, all
outstanding shares of capital stock on a particular Level contemporaneously, and
if less than full dividends are paid on or if declared and set apart for payment
on a particular Level, then the same percentage of the respective dividend rate
on all shares on such Level shall be paid or declared and set apart for payment.

          .      Level 1:    $0.48 per share of Series F Preferred Stock; and
                             $0.34 per share of Series E Preferred Stock

          .      Level 2:    $0.32 per share of Series D Preferred Stock;
                             $80.00 per share of Series C Preferred Stock; and

          .      Level 3:    $0.08 per share of Series A Preferred Stock.
 
          .      Level 4:    If a dividend is declared with respect to the
                             Common Stock, then a contemporaneous dividend must
                             be declared with respect to the Series E and Series
                             F Preferred Stock in an amount equal to that which
                             would be received if the Series E and Series F
                             Preferred Stock had been converted to Common Stock
                             on the declaration date of such dividend.

     3.1  Preferential Amounts. In the event of any voluntary or involuntary
liquidation, dissolution or winding up of the Corporation, any distribution of
the assets or surplus funds of the Corporation to holders of shares of capital
stock of the Corporation by reason of their ownership thereof must take place as
set herein. Holders of shares of certain series of Preferred Stock shall be
entitled to receive such distributions prior and in preference to any such
distributions on certain other shares of capital stock of the Corporation, as
set forth below in terms of four "Tiers," to be designated and known as "Tier
1," "Tier 2," "Tier 3" and "Tier 4." No such distributions shall be made with
respect to a particular Tier until all such preferential distributions on the
preceding Tiers have been made. For example, such distributions on Tier 3 shall
not be made until the full preferential distributions on Tier 1 and Tier 2 have
been made. If the assets or surplus funds of the Corporation available for
distribution to stockholders are insufficient to permit payment in full of
amounts to which the holders of the outstanding

                                       2

available assets and funds shall be distributed ratably among the holders of the
outstanding shares on such Tier in proportion to the full preferential
distribution each such holder is otherwise entitled to receive. The preferential
amounts set forth below shall be adjusted for any stock dividends, combinations
or splits with respect to such shares.

                           accrued or declared but unpaid dividends thereon (the

for payment of the Series A Preferential Amount, the Series B Preferential
Amount, the Series C Preferential Amount, the Series D Preferential Amount, the
Series E Preferential Amount and the Series F Preferential Amount, the remaining
assets or surplus funds of the Corporation available for distribution upon such
liquidation, dissolution or winding up shall be divided pro rata among the
holders of Common Stock and Preferred Stock, treating the Preferred Stock as if
converted to Common Stock on the date of such liquidation, dissolution or
winding up.

     3.3  Limits on Participation. In the event of such distribution upon a
liquidation, dissolution or winding up of the Corporation, the amount otherwise
payable to a holder of Preferred Stock shall not exceed the amount per share set

                                       8

 
converted" into Common Stock basis) realized by the Company's shareholders from
the consideration received in said consolidation or merger, which value shall be
determined by the mutual agreement between the Company and the Purchaser. If the
Company and the Purchaser do not reach mutual agreement as to said value, then
said value shall be determined by a nationally recognized investment banking
firm which is mutually selected by the Company and the Purchaser, with the fees
for obtaining said valuation determination to be borne equally by the Company
and the Purchaser. Such conversion shall occur following any adjustment to the
Series F Conversion Price pursuant to Section 6.5.

               (d)  Operational Plan.  Each share of Series F Preferred Stock
shall automatically be converted into shares of Common Stock at the then
effective Series F Conversion Price immediately upon the adoption by resolution
of the Corporation's Board of Directors of an operational plan for the
Corporation which provides for the Corporation to continue its operations in the
ordinary course of business through revenues, working capital or other resources
through at least December 31, 1998 without any further infusion of capital from
investors through debt or equity investment in the Corporation; provided,
however, that any such operational plan, as determined in good faith by the
Corporation's Board of Directors, must be consistent with the intent of the then
current annual Product Development Plan pursuant to the Distribution Agreement
by and between the Corporation and Cobe BCT, Inc., dated October 22, 1993. In
the event that the conversion of the Series F Preferred Stock into shares of
Common Stock shall occur pursuant to this Section 6.3.4(d), the Series F
Conversion Price shall equal eighty percent (80%) of the fair market value of a
share of Series F Preferred Stock, as determined by the mutual agreement of the
Company and the Purchaser. If the Company and the Purchaser do not reach mutual
agreement as to said value, then said value shall be determined by a nationally
recognized investment banking firm which is mutually selected by the Company and
the Purchaser, with the fees for obtaining said valuation determination to be
borne equally by the Company and the Purchaser. Such conversion shall occur
following any adjustment to the Series F Conversion Price pursuant to Section
6.5.

               (e)  December 1, 1997.  If not earlier converted pursuant to this
Section 6.3.4, each share of Series F Preferred Stock shall automatically be
converted into shares of Common Stock at the then effective Series F Conversion
Price on December 1, 1997; provided, however, that in the event that prior to
December 1, 1997, the Corporation has entered into a letter of intent (whether
or not such letter of intent is intended to be binding or non-binding on the
Corporation) which contemplates a transaction which would trigger automatic
conversion of the Series F Preferred Stock into Common Stock pursuant to
paragraph (a), (b) or (c) of this Section 6.3.4 and contemplates the
consummation of the closing of such transaction on or before February 1, 1998,
then each share of Series F Preferred Stock shall automatically be converted
into shares of Common Stock at then effective Series F Conversion Price on
February 2, 1998. In the event that the conversion of the Series F Preferred
Stock into shares of Common Stock shall occur pursuant to this Section 6.3.4(e),
the Series F Conversion Price shall be $4.65, as adjusted pursuant to Section
6.5.

                                       9

 
     6.4  Mechanics of Conversion.  No fractional shares of Common Stock shall
be issued upon conversion of shares of Preferred Stock. In lieu of any
fractional shares to which the holder would otherwise be entitled, the
Corporation shall pay cash equal to such fraction multiplied by the then
effective Applicable Conversion Price for the series. Before any holder of
Preferred Stock shall be entitled to convert the same into shares of Common
Stock pursuant to Section 6.2, such holder shall surrender the certificate or
certificates therefor at the principal office of the Corporation or of any
transfer agent for such stock and shall give written notice to the Corporation
at such office that such holder elects to convert the same and shall state
therein the name or names of the nominees in which such holder wishes the
certificate or certificates for shares of Common Stock to be issued. The
Corporation shall, as soon as practicable thereafter, issue and deliver at such
office to such holder of Preferred Stock, or to their respective nominee or
nominees, a certificate or certificates for the number of shares of Common Stock
to which such holder or nominee shall be entitled as aforesaid, together with
cash in lieu of any fraction of a share. Such conversion shall be deemed to have
been made immediately prior to the close of business on the date of such
surrender of the shares of Preferred Stock to be converted, and the person or
persons entitled to receive the shares of Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder or holders of
such shares of Common Stock on such date.

     6.5  Adjustments to Conversion Prices.

          6.5.1  Special Definitions.  For purposes of this Section 6.5, the
following definitions shall apply:

               (a)  "Options" shall mean rights, options or warrants to
subscribe for, purchase or otherwise acquire either Common Stock or Convertible
Securities (defined below).

               (b)  "Original Issue Date" shall mean the date on which a share
of a particular series of Preferred Stock was first issued.

               (c)  "Convertible Securities" shall mean any evidence of
indebtedness, shares or other securities directly or indirectly convertible into
or exchangeable for Common Stock.

               (d)  "Additional Shares of Common Stock" shall mean all shares of
Common Stock issued (or, pursuant to Section 6(D)(3) deemed to be issued) by the
Corporation after the Original Issue Date, other than shares of Common Stock
issued or issuable:

                    (i)   upon conversion of shares of Preferred Stock;

                    (ii)  to the University of Michigan, Stephen G. Emerson,
Bernhard O. Palsson, Michael F. Clarke, or to the officers, employees,
consultants or directors of the Corporation pursuant to any stock purchase plan
or arrangement, stock

                                      10

 
option plan, or other stock incentive plan or agreement approved by the
Corporation's Board of Directors; or

                    (iii) by way of dividend or other distribution on shares
excluded from the definition of Additional Shares of Common Stock by the
foregoing clauses (i) or (ii), or this clause (iii).

          6.5.2  No Adjustment of Applicable Conversion Price.  No adjustment in
the Applicable Conversion Prices for the series of Preferred Stock shall be made
with respect to the issuance of Additional Shares of Common Stock or otherwise,
unless the consideration per share (determined pursuant to Section 6.5.5 hereof)
for an Additional Share of Common Stock issued or deemed to be issued by the
Corporation is less than the Applicable Conversion Price for such series in
effect on the date of, and immediately prior to, the issue of such Additional
Share of Common Stock.

          6.5.3  Deemed Issuances of Additional Shares of Common Stock.

               (a)  Options and Convertible Securities.  In the event the
Corporation at any time or from time to time after the Original Issue Date of a
particular series shall issue any Options or Convertible Securities or shall fix
a record date for the determination of holders of any class of securities
entitled to receive any such Options or Convertible Securities, then the maximum
number of shares (as set forth in the instrument relating thereto without regard
to any provisions contained therein for a subsequent adjustment of such number)
of Common Stock issuable upon the exercise of such Options or, in the case of
Convertible Securities and Options therefor, the conversion or exchange of such
Convertible Securities, shall be deemed to be Additional Shares of Common Stock
issued as of the time of such issue or, in case such a record date shall have
been fixed, as of the close of business on such record date, provided that
Additional Shares of Common Stock shall not be deemed to have been issued with
respect to the Preferred Stock unless the consideration per share (determined
pursuant to Section 6.5.5 hereof) of such Additional Shares of Common Stock
would be less than the Applicable Conversion Price of such series in effect on
the date of and immediately prior to such issue, or such record date, as the
case may be, and provided further that in any case in which Additional shares of
Common Stock are deemed to be issued the following provisions shall apply:

               (i)  Exercise or Conversion.  No further adjustment in the
Applicable Conversion Price shall be made upon the subsequent issue of
Convertible Securities or shares of Common Stock upon the exercise of such
Options or conversion or exchange of such Convertible Securities.

               (ii) Increase or Decrease.  If such Options or Convertible
Securities by their terms provide, with the passage of time or otherwise, for
any increase in the consideration payable to the Corporation, or decrease in the
number of shares of Common Stock issuable, upon the exercise, conversion or
exchange thereof, the Applicable Conversion Price computed upon the original
issue thereof (or upon the

                                      11

 
occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities.

          (iii) Expiration. Upon the expiration of any such Options or any
rights of conversion or exchange under such Convertible Securities which shall
not have been exercised, the Applicable Conversion Prices computed upon the
original issue thereof (or upon the occurrence of a record date with respect
thereto), and any subsequent adjustments based thereon, shall, upon such
expiration, be recomputed as follows:

                         (A) Underlying Common Stock. In the case of Convertible
Securities or Options for Common Stock, any such subsequent adjustments shall be
recomputed as if the only Additional Shares of Common Stock issued were the
shares of Common Stock, if any, actually issued upon the exercise of such
Options or the conversion or exchange of such Convertible Securities and the
consideration received therefor was the consideration actually received by the
Corporation for the issue of all such Options, whether or not exercised, plus
the consideration actually received by the Corporation upon such exercise, or
for the issue of all such Convertible Securities which were actually converted
or exchanged, plus the additional consideration, if any, actually received by
the Corporation upon such conversion or exchange.

                         (B) Underlying Convertible Securities. In the case of
Options for Convertible Securities, any such subsequent adjustments shall be
recomputed as if only the Convertible Securities, if any, actually issued upon
the exercise thereof were issued at the time of issue of such Options, and the
consideration received by the Corporation for the Additional Shares of Common
Stock deemed to have been then issued was the consideration actually received by
the Corporation for the issue of all such Options, whether or not exercised,
plus the consideration deemed to have been received by the Corporation
(determined pursuant to Section 6.5.5 upon the issue of the Convertible
Securities with respect to which such Options were actually exercised.

                    (iv) Limitation. No readjustment pursuant to clause (ii) or
(iii) above shall have the effect of increasing the Applicable Conversion Price
to an amount which exceeds the lower of (A) such Applicable Conversion Price on
the original adjustment date, or (B) such Applicable Conversion Price that would
have resulted from any issuance of Additional Shares of Common Stock between the
original adjustment date and such readjustment date (nor shall any shares issued
upon conversion prior to such readjustment be affected by such readjustment).

                    (v) Short-Term Options. In the case of any Options that
expire by their terms not more than thirty (30) days after the date of issue
thereof, no adjustment of the Applicable Conversion Price shall be made until
the expiration or exercise of all such Options, whereupon such adjustment shall
be made in the same manner as provided in clause (iii) above.

                                      12

 
                    (vi) Date of Issuance. If such record date shall have been
fixed and such Options or Convertible Securities are not issued on the date
fixed therefor, the adjustment previously made in the Applicable Conversion
Price which became effective on such record date shall be cancelled as of the
close of business on such record date, and thereafter the Applicable Conversion
Price shall be adjusted pursuant to this Section 6.5.3 as of the actual date of
their issuance.

               (b) Stock Dividends, Stock Distributions and Subdivisions. In the
event the Corporation at any time or from time to time after the Original Issue
Date shall declare or pay any dividend or make any other distribution on the
Common Stock payable in Common Stock, or effect a subdivision of the outstanding
shares of Common Stock (by reclassification or otherwise than by payment of a
dividend in Common Stock), then and in any such event, Additional Shares of
Common Stock shall be deemed to have been issued as follows:

                    (i) Dividend or Distribution. In the case of any such
dividend or distribution, immediately after the close of business on the record
date for the determination of holders of any class of securities entitled to
receive such dividend or distribution.

                    (ii) Subdivision. In the case of any such subdivision, at
the close of business on the date immediately prior to the date upon which such
corporate action becomes effective.

          If such record date shall have been fixed and such dividend shall not
have been fully paid on the date fixed therefor, the adjustment previously made
in the Applicable Conversion Price which became effective on such record date
shall be cancelled as of the close of business on such record date, and
thereafter the Applicable Conversion Price shall be adjusted pursuant to this
Section 6.5.3 as of the time of actual payment of such dividend.

          6.5.4  Anti-Dilution Adjustment of Applicable Conversion Price Upon
Issuance of Additional Shares of Common Stock.

               (a) Series A, Series B and Series E Preferred Stock. In the event
the Corporation, at any time after the Original Issue Date, shall issue
Additional Shares of Common Stock (including Additional Shares of Common Stock
deemed to be issued pursuant to Section 6.5.3 but excluding Additional Shares of
Common Stock issued pursuant to Section 6.5.3(b) which event is dealt with in
Section 6.5.6 hereof) without consideration or for a consideration per share
less than the Series A Conversion Price, Series B Conversion Price or Series E
Conversion Price in effect on the date of and immediately prior to such
issuance, then and in such event, the Applicable Conversion Price for the
affected Series A, Series B and Series E Preferred Stock, respectively, shall be
reduced, concurrently with such issuance, in order to increase the number of
shares of Common Stock into which shares of such series of Preferred Stock is
convertible, to a price (calculated to the nearest cent) determined by the
following formula:

                                      13

 
                            C
                          -----
     CP(1) = CP(O) x CS + CP(O)
                     ----------
                      CS + AS

     where:

     CP(O) = the Applicable Conversion Price for Series A, Series B or Series E
     Preferred Stock in effect on the date of and immediately prior to such
     issuance;

     CP(1) = the Applicable Conversion Price for Series A, Series B or Series E
     Preferred Stock as so adjusted;

     CS = the number of shares of Common Stock outstanding immediately prior to
     such issuance (including shares of Common Stock issuable upon conversion or
     exercise of any Convertible Securities or Options);

     C = the aggregate consideration received by the Corporation for the total
     number of Additional Shares of Common Stock so issued; and

     AS = the number of such Additional Shares of Common Stock so issued.

Notwithstanding the foregoing, the Applicable Conversion Price for Series A,
Series B or Series E Preferred Stock shall not be so reduced if the amount of
such reduction would be an amount less than $0.01, but any such amount shall be
carried forward and applied toward any subsequent reduction which, together with
such amount and any other amount or amounts so carried forward, shall aggregate
$0.01 or more.

               (b) Series D Preferred Stock.

                    (i) Ratchet Adjustment. In the event the Corporation shall
issue Additional Shares of Common Stock (including Additional Shares of Common
Stock deemed to be issued pursuant to Section 6.5.3, but excluding Series D
Preferred Stock and Additional Shares of Common Stock issued pursuant to Section
6.5.3(b) (which event is dealt with in Section 6.5.6 hereof)), either without
consideration or for a consideration per share less than the Series D Conversion
Price in effect on the date of and immediately prior to such issuance, wherein
the aggregate consideration for such issuance received by the Corporation is at
least $2,000,000, the following will be applicable:

                         (A) Single Transaction. In a private financing
transaction (including a transaction with multiple closings for the sale of
shares of the same class at the same price per share within any twelve-month
period), the Series D Conversion Price shall be reduced concurrently with such
issuance to a price equal to the consideration per share (as determined pursuant
to Section 6.5.5 hereof) received by

                                      14

 
the Corporation for such Additional Shares of Common Stock; provided, however,
that in no event shall the Series D Conversion Price be reduced to less than
$3.00.

                         (B) Multiple Transactions. In multiple transactions at
different per share prices during any twelve-month period, the Series D
Conversion Price shall be reduced to an amount equal to the weighted average
consideration received by the Corporation for such Additional Shares of Common
Stock during such twelve-month period (but in no event shall the Series D
Conversion Price be reduced to less than $3.00. Such weighted average
consideration shall be determined by dividing the aggregate consideration
received by the Corporation for the Additional Shares of Common Stock over such
twelve-month period by the aggregate number of Additional Shares of Common Stock
issued over the same period.

                    (ii) Formula Adjustment. In the event the Corporation shall
issue Additional Shares of Common Stock (including Additional Shares of Common
Stock deemed to be issued pursuant to Section 6.5.3 but excluding Series D
Preferred Stock and Additional Shares of Common Stock issued pursuant to Section
6.5.3(b), which event is dealt with in Section 6.5.6 for a per share
consideration less than the Series D Conversion Price in effect on the date of
and immediately prior to such issuance, in a single transaction or in a series
of transactions, and for aggregate consideration less than $2,000,000 during any
twelve-month period, then the Series D Conversion Price shall be adjusted for
such Additional Shares of Common Stock pursuant to the formula provided in
Section 6.5.4(a) as if the Series D Preferred Stock were Series B Preferred
Stock (except for the Applicable Conversion Price which shall be the Series D
Conversion Price).

                    (iii) Single Adjustment. For purposes of this Section
6.5.4(b) any issuance of Additional Shares of Common Stock shall be included in
only one twelve-month period (and in only one adjustment of the Series D
Conversion Price), which period shall be the earliest twelve-month period which
may be applicable (and which adjustment shall be the adjustment to be made with
respect to the earliest applicable twelve-month period). After the first twelve-
month period with respect to which an adjustment is made to the Series D
Conversion Price, any new twelve-month period shall be deemed to commence on the
date of issuance of Additional Shares of Common Stock first occurring more than
twelve months following the date of issuance of Additional Shares of Common
Stock which caused the most recent prior twelve-month period to begin.

               (c) Series F Preferred Stock. In the event the Corporation shall
issue Additional Shares of Common Stock (including Additional Shares of Common
Stock deemed to be issued pursuant to Section 6.5.3, but excluding Series F
Preferred Stock and Additional Shares of Common Stock issued pursuant to Section
6.5.3(b), which event is dealt with in Section 6.5.6, either without
consideration or for a consideration per share less than the Series F Conversion
Price in effect on the date of and immediately prior to such issuance, in a
private financing transaction (including a transaction with multiple closings
for the sale of shares of the same class at the same

                                      15

 
price per share within any twelve-month period), wherein the aggregate
consideration for such issuance received by the Corporation is at least
$1,000,000, then the Series F Conversion Price shall be adjusted for such
Additional Shares of Common Stock pursuant to the formula provided in Section
6.5.4(a) as if the Series F Preferred Stock were Series B Preferred Stock
(except the Applicable Conversion Price shall be the Series F Conversion Price);
provided, however, that the adjustment to the Series F Conversion Price provided
for in this Section 6.5.4(c) shall apply only to the Corporation's first such
private financing following the Original Issue Date of the Series F Preferred
Stock.

          6.5.5  Determination of Consideration.  For purposes of this Section
6.5 the consideration received by the Corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

               (a)  Cash and Property.  Such consideration shall be computed as
follows:

                    (i)   Cash.  Insofar as it consists of cash, such
consideration shall be computed at the aggregate amount of cash received by the
Corporation;

                    (ii)  Property.  Insofar as it consists of property other
than cash, such consideration shall be computed at the fair value thereof at the
time of such issue, as determined in good faith by the Board of Directors; and

                    (iii) Combination.  In the event Additional Shares of Common
Stock are issued together with other shares or securities or other assets of the
Corporation for consideration which covers both, such consideration shall be the
proportion of such consideration so received, computed as provided in clauses
(i) and (ii) above, as determined in good faith by the Board of Directors.

               (b)  Options and Convertible Securities.  The consideration per
share received by the Corporation for Additional Shares of Common Stock deemed
to have been issued pursuant to Section 6.5.3(a), relating to Options and
Convertible Securities, shall be determined by dividing:

                    (i)   the total amount, if any, received or receivable by
the Corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration) payable to
the Corporation upon the exercise of such Options or the conversion or exchange
of such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the
conversion or exchange of such Convertible Securities; by

                    (ii)  the maximum number of shares of Common Stock (as set
forth in the instruments relating thereto, without regard to any provision
contained

                                      16

 
therein for a subsequent adjustment of such number) issuable upon the exercise
of such Options or the conversion or exchange of such Convertible Securities.

          6.5.6  Adjustment for Dividends or Combinations.

               (a)  Stock Dividends, Distributions or Subdivisions.  In the
event the Corporation shall issue Common Stock pursuant to Section 6.5.3(b) in a
stock dividend, stock distribution or subdivision, the Applicable Conversion
Price in effect immediately prior to such stock dividend, stock distribution or
subdivision shall, concurrently with the effectiveness of such stock dividend,
stock distribution or subdivision, be proportionately decreased.

               (b)  Combinations or Consolidations.  In the event the
outstanding shares of Common Stock shall be combined or consolidated, by
reclassification or otherwise, into a lesser number of shares of Common Stock,
the Applicable Conversion Price in effect immediately prior to such combination
or consolidation shall, concurrently with the effectiveness of such combination
or consolidation, be proportionately increased.

          6.5.7  Adjustment for Merger or Reorganization.  In the event of any
consolidation or merger of the Corporation with or into another corporation or
the sale or conveyance of all or substantially all of the assets of the
Corporation to another corporation, each share of Series A, Series B, Series C,
Series D and Series E Preferred Stock shall thereafter be convertible into the
number of shares of stock or other securities or property to which a holder of
the number of shares of Common Stock of the Corporation deliverable upon
conversion of such series would have been entitled upon such consolidation,
merger or conveyance, and, in any such case, appropriate adjustment (as
determined by the Board of Directors) shall be made in the application of the
provisions herein set forth with respect to the rights and interest thereafter
of the holders of the series, in order that the provisions set forth herein
(including provisions with respect to changes in and other adjustments of the
Applicable Conversion Price) shall thereafter be applicable, as nearly as
reasonably may be, in relation to any shares of stock or other property
thereafter deliverable upon the conversion of that series of Preferred Stock.
However, in the case of any merger or consolidation which is treated as a
liquidation, dissolution or winding up of the affairs of the Corporation
pursuant to Section 3.4, each share of Series A, Series B, Series C, Series D
and Series E Preferred Stock shall not be converted into shares of stock or
other securities or property of the resulting corporation, but shall be
cancelled and surrendered to the Corporation upon distribution to the holders of
Series A, Series B, Series C, Series D and Series E Preferred Stock of all cash
or other property to which they are entitled pursuant to Section 3 as a result
of such transaction being treated as a liquidation, dissolution, or winding up
under Section 3.4.

          6.5.8  Adjustment to Series C Conversion Price for Distributions to
Holders of Common Stock.  In the event that the Corporation shall distribute to
the holders of its Common Stock (whether pursuant to a reclassification, merger
or consolidation or

                                      17

 
otherwise) evidences of its indebtedness or assets (including cash, securities,
intangible assets or other property), then the Series C Conversion Price shall
be adjusted so that the number of shares of Common Stock into which a share of
Series C Preferred Stock is convertible equals the number of shares of Common
Stock determined as follows: multiply the number of shares of Common Stock into
which each share of Series C Preferred Stock is convertible at the then
effective Series C Conversion Price by a fraction, the numerator of which shall
be the Series C Conversion Price effective on the record date for determination
of shareholders entitled to receive such distribution, and the denominator of
which shall be such Series C Conversion Price less the fair market value of such
property, as determined in good faith by the Board of Directors of the
Corporation, distributed with respect to each share of Common Stock. Such
adjustment to the Series C Conversion Price shall be made whenever any such
distribution is made.

     6.6  No Impairment.  The Corporation will not, by amendment of these
Restated Articles of Incorporation or through any reorganization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed hereunder by the Corporation but
will at all times in good faith assist in the carrying out of all the provisions
of this Section 6 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of the
Preferred Stock against impairment.

     6.7  Certificate as to Adjustments.  Upon the occurrence of each adjustment
or readjustment of the Applicable Conversion Prices pursuant to this Section 6,
the Corporation at its expense shall promptly compute such adjustments or
readjustments in accordance with the terms hereof and furnish to each holder of
Preferred Stock a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based.
The Corporation shall, upon the written request at any time from any holder of
Preferred Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the
Applicable Conversion Price at the time in effect, and (iii) the number of
shares of Common Stock and the amount, if any, of other property which at the
time would be received upon the conversion of such holder's shares of Preferred
Stock.

     6.8  Notices of Record Date.  In the event of any taking by the Corporation
of a record of the holders of any class of securities (other than Preferred
Stock) for the purposes of determining the holders thereof who are entitled to
receive any dividend (other than a cash dividend which is the same as cash
dividends paid in previous quarters) or other distribution, the Corporation
shall mail to each holder of Preferred Stock at least ten (10) days prior to the
date specified therein, a notice specifying the date on which any such record is
to be taken for the purpose of such dividend or distribution.

     6.9  Common Stock Reserved.  The Corporation shall reserve and keep

Stock as shall from time to time be sufficient to effect conversion of the
Preferred Stock. The Corporation shall not take any corporate action which would
require an adjustment in the number of shares of Common Stock into which any
share of Preferred Stock is convertible unless either (i) immediately after such
corporate action is taken and the transactions contemplated thereby are
consummated, the number of authorized and unissued shares of Common Stock would
be sufficient to effect the conversion of all outstanding shares of Preferred
Stock at the Applicable Conversion Prices then in effect, or (ii) concurrently
with the taking of such corporate action, the Corporation shall take such
corporate action as, in the opinion of its counsel, may be necessary to increase
its authorized and unissued shares of Common Stock to such number as shall be
sufficient to provide for such conversion.

          6.10  Taxes Upon Conversion of Series C Preferred Stock.  The
Corporation shall pay any and all taxes that may be payable in respect of the
issue or delivery of shares of Common Stock on conversion of shares of Series C
Preferred Stock pursuant hereto. The Corporation shall not, however, be required
to pay any tax which may be payable in respect of any transfer involved in the
issue and delivery of shares of Common Stock in a name other than that in which
the shares of Series C Preferred Stock so converted were registered, and no such
issue or delivery shall be made unless and until the person requesting such
issue has paid to the Corporation the amount of any such tax or has established,
to the satisfaction of the Corporation, that such tax has been paid.

                                  ARTICLE VII

          1.  Director Liability.  A director of the Corporation shall not be
personally liable to the Corporation or its shareholders for monetary damages
for breach of fiduciary duty as a director. However, this provision does not
eliminate or limit the liability of a director for any of the following:

               (a)  any breach of the director's duty of loyalty to the
Corporation or its shareholders;

               (b)  any acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law;

               (c)  a violation of Section 551(1) of the Michigan Business
Corporation Act, as amended (the "MBCA");

               (d)  a transaction from which the director derived an improper
personal benefit; or

               (e)  an act or omission occurring before the date these Articles
of Incorporation became effective in accordance with the pertinent provisions of
the MBCA.

Any repeal, amendment or other modification of this Article VII shall not
adversely affect any right or protection of a director of the Corporation
existing at the time of such repeal, amendment or other modification.

          If the MBCA is amended, after this Article becomes effective, to
authorize corporate action further eliminating or limiting personal liability of
directors, then the liability of directors shall be eliminated or limited to the
fullest extent permitted by the MBCA as so amended.

          2.  Control Share Acquisitions.  Chapter 7B of the MBCA, known as the
"Stacey, Bennett, and Randall shareholder equity act," does not apply to control
share acquisitions of shares of the Corporation.

Corporation shall be held at the principal office of the Corporation, or at such
other place as may be set forth in the notice thereof, in August or September of
each year, at a date and time as designated by the Board of Directors, for the
purpose of election of Directors to succeed those whose terms expire and for the
transaction of such other business as may properly come before the meeting. The
Board of Directors, for good and sufficient reasons, may schedule the annual
meeting at any other time, and notice shall be given or waived as provided in
Section 2.4 hereof.

     Section 2.2  Special Meetings.  Special Meetings of the shareholders
                  ----------------                                       
(or of any specific class thereof), for any purpose or purposes, unless
otherwise prescribed by statute or by the Articles of Incorporation, may be
called by the President and shall be called by the President or Secretary at the
request in writing of a majority of the Board of Directors, or at the request in
writing of a shareholder or shareholders owning at least ten percent (10%) of
the number of shares of stock (or, with respect to meetings of a specific class,
the number of shares of such specific class thereof) of the Corporation issued
and outstanding and entitled to vote.  Such request shall state the purpose or
purposes of the proposed meeting.  Upon the closing of the first sale of the
Corporation's common stock

                                      -2-

 
pursuant to a firmly underwritten registered public offering (the "IPO"),
special meetings of the shareholders may be called only by the President and
shall be called by the President at the request in writing of a majority of the
Directors then in office, and shall be held at such place, on such date, and at
such time as the President or shall fix.  Business transacted at special
meetings shall be confined to the purpose or purposes stated in the notice.

     Section 2.3  List of Shareholders.  The officer who has charge of the stock
                  --------------------
ledger of the Corporation shall prepare and make, at least ten (10) days before
every meeting of shareholders, a complete list of the shareholders entitled to
vote at the meeting, arranged in alphabetical order, and showing the address of
each shareholder and the number of shares registered in the name of each
shareholder. Such list shall be open to the examination of any shareholder, for
any purpose germane to the meeting, during ordinary business hours, for a period
of at least ten (10) days prior to the meeting, either at a place within the
city where the meeting is to be held, which place shall be specified in the
notice of the meeting, or, if not so specified, at the place where the meeting
is to be held. The list shall also be produced and kept at the time and place of
the meeting during the whole time thereof, and may be inspected by any
shareholder who is present.

     Section 2.4  Notice of Meetings.  Written notice of the time, place and
                  ------------------                                    
purposes of the meeting of shareholders shall be given not less than 10 nor
more than 60 days before the date fixed for such meeting to each shareholder of
record entitled to vote at the meeting.  Notice shall be deemed duly served when
the same has been personally delivered or deposited in the United States Mail,
with postage fully prepaid, addressed to the shareholder at such shareholder's
address as it appears on the records of the Corporation.  Written notice may
also be given by facsimile or telegram, and such notice shall be deemed to be
given when the recipient receives the notice personally, or when confirmation of
transmission of the notice to the shareholder's address as it appears on the
books and records of the Corporation has been delivered to the Corporation or to
the equipment transmitting such notice.  Such notice shall be given by or under
the direction of the Secretary of the Corporation, and in the absence or refusal
of the Secretary to give such notice, notice shall be given by or under the
direction of any other officer of the Corporation.  No notice need be given of
an adjourned meeting of the shareholders provided the time and place to which
such meeting is adjourned is announced at the meeting at which the adjournment
is taken and at the adjourned meeting only such business is transacted as might
have been transacted at the original meeting.  If the adjournment is for more
than thirty (30) days, or if after the adjournment a new record date is fixed
for the adjourned meeting, a notice of the adjourned meeting shall be given to
each shareholder of record entitled to vote at the meeting.  A waiver of such
notice in writing, signed by a person entitled to said notice, whether before or
after the time of the meeting, shall be deemed equivalent to said notice.
Attendance of a person at a meeting of shareholders, in person or by proxy,
shall constitute a waiver of such notice, except when the attendance is for the
express and sole purpose of objecting to the transaction of any business,

                                     -3-

 
clearly stated at the commencement of the meeting, by reason of a claim that a
meeting was not lawfully called or convened.

 
     Section 2.5  Transaction of Business.  At an annual or special meeting of
                  -----------------------
the shareholders, only such business shall be conducted as shall have been
properly brought before the meeting. To be properly brought before a meeting,
business must be (a) specified in the notice of meeting (or any supplement
thereto) given by or at the direction of the Secretary or other officer of the
Corporation, (b) properly brought before the meeting by or at the direction of
the Board of Directors, (c) properly brought before an annual meeting by a
shareholder, or (d) properly brought before a special meeting by a shareholder,
but if, and only if, the notice of a special meeting provides for business to be
brought before the meeting by shareholders. For business to be properly brought
before a meeting by a shareholder, the shareholder must have given timely notice
thereof in writing to the Secretary of the Corporation. To be timely, a
shareholder proposal to be presented at an annual meeting shall be received at
the Corporation's principal executive offices not less than 120 calendar days in
advance of the date that the Corporation's (or the Corporation's predecessor's)
proxy statement was released to shareholders in connection with the previous
year's annual meeting of shareholders, except that if no annual meeting was held
in the previous year or the date of the annual meeting has been changed by more
than 30 calendar days from the date contemplated at the time of the previous
year's proxy statement, or in the event of a special meeting, notice by the
shareholder to be timely must be received not later than the close of business
on the tenth day following the day on which such notice of the date of the
meeting was mailed or such public disclosure was made. A shareholder's notice to
the Secretary shall set forth as to each matter the shareholder proposes to
bring before the annual or special meeting (a) a brief description of the
business desired to be brought before the annual or special meeting and the
reasons for conducting such business at the special meeting, (b) the name and
address, as they appear on the Corporation's books, of the shareholder proposing
such business, (c) the class and number of shares of the Corporation which are
beneficially owned by the shareholder, and (d) any material interest of the
shareholder in such business.

     Section 2.6  Quorum.  The holders of a majority of the stock issued and
                  ------
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at all meetings of the shareholders (or any
specific class thereof) for the transaction of business except as otherwise
provided by statute or by the Articles of Incorporation. If, however, such
quorum shall not be present or represented by any meeting of the shareholders,
the chairman of the meeting or the holders of a majority of shares of stock
entitled to vote thereat who are present, in person or represented by proxy,
shall have the power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum shall be present or
represented.

                                      -4-

 
     Section 2.7  Voting and Record Date.  In order that the Corporation
                  ----------------------                                
may determine the shareholders entitled to notice of or to vote at any meeting
of shareholders or any adjournment thereof, or to express consent to corporate
action in writing without a meeting, or entitled to receive payment of any
dividend or other distribution of allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion or exchange of stock or
for the purpose of any other lawful action, the Board of Directors may fix a
record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the Board of Directors, and
which record date shall not be (i) more than sixty (60) nor less than ten (10)
days before the date of such meeting, nor (ii) more than ten (10) days after the
date upon which the resolution fixing the record date is adopted by the Board of
Directors for action by shareholder consent in writing without a meeting, nor
(iii) more than sixty (60) days prior to any other action.  If a record date is
not fixed (a) the record date for determination of shareholders entitled to vote
at a meeting of shareholders shall be the close of business on the day next
preceding the day on which notice of such meeting is given, and (b) the record
date for determining shareholders for any purpose other than that specified in
subdivision (a) shall be the close of business on the day on which the
resolution of the Board relating thereto is adopted.  When a determination of
shareholders of record entitled to vote at a meeting of shareholders has been
made as provided in this Section, the determination applies to any adjournment
of the meeting, unless the Board fixes a new record date under this Section for
the adjourned meeting.

     Section 2.8  Proxies.  A proxy, given by a shareholder to another person,
                  -------
authorizing such other person to vote the shares of such shareholder, shall be
in writing and signed by the shareholder or his authorized agent or
representative. A proxy shall not be valid after the expiration of three (3)
years from its date unless otherwise provided therein. All proxies shall be
filed with the Secretary at or before the meeting at which they are intended to
be used. A proxy shall be deemed sufficient if it appears on its face to confer
the requisite authority and is signed by the owner of the stock to be voted. No
witnesses to the execution of any proxy shall be required.

     Section 2.9  Inspectors.  The Board of Directors, in advance of a
                  ----------                                          
shareholders meeting, may appoint one or more inspectors to act at the meeting
or any adjournment thereof.  If inspectors are not so appointed, the person
presiding at a shareholders meeting may, and on request of a shareholder
entitled to vote thereat shall, appoint one or more inspectors.  In case a
person appointed fails to appear or act, the vacancy may be filled by
appointment made by the Board of Directors in advance of the meeting or at the
meeting by the person presiding thereat.  The inspectors shall determine the
number of shares outstanding and the voting power of each, the shares
represented at the meeting, the existence of a quorum, the validity and effect
of proxies, and shall receive votes, ballots or consents, hear and determine
challenges and questions arising in connection with the right to vote, count and
tabulate votes, ballots or consents, determine the result, and do such acts as
are proper to conduct the election or vote with fairness

                                      -5-

 
to all shareholders.  On request of the person presiding at the meeting or a
shareholder entitled to vote thereat, the inspectors shall make and execute a
written report to the person presiding at the meeting of any of the facts found
by them and matters determined by them.  The report shall be prima facie
evidence of the facts stated and of the vote as certified.

     Section 2.10  Action by Written Consent.  The shareholders of the
                   -------------------------                          
Corporation shall have the ability to take action without a meeting only as
provided in the Articles of Incorporation.

written instructions to the contrary, from the pledgee and pledgor, pledged

          (e)  Voting by Guardian of Minor.  Shares standing in the name of a

guardian, in person or by proxy, or in the absence of such representation by his
guardian, by the minor, in person or by proxy, whether or not the Corporation

with the vote or consent of the majority of the persons in whose names the
shares stand.  If only one such person is present in person or by proxy, he may
vote all the shares, and all the shares standing in the names of such persons
are represented for the purpose of determining a quorum.  This applies to the
voting of shares by two or more administrators, executors, trustees, or other
fiduciaries, unless the instrument or order of court appointing them otherwise
directs.


                        ARTICLE III  BOARD OF DIRECTORS
                        -------------------------------

     Section 3.1  General Powers.  The property, affairs and business of the
                  --------------                                            
Corporation shall be managed by the Board of Directors.

     Section 3.2  Number, Qualification and Term of Office.  Unless otherwise
                  ----------------------------------------                   
provided in the Articles of Incorporation, the Board of Directors shall be
divided into three classes, as nearly equal in numbers as the then total number
of directors constituting the entire Board of Directors permits, with the term
of office of one class expiring each year.  The term of office of directors in
the first class shall expire at the first annual meeting of shareholders after
their election, the term of office of directors in the second class shall expire
at the second annual meeting of shareholders after their election, and the term
of office of directors in the third class shall expire at the third annual
meeting of shareholders after their election.  The directors elected at the 1994
Annual Shareholders Meeting will be classified into terms of one, two or three
years, by resolution of the Board of Directors.  At each annual meeting of
shareholders after such classification of the Board of Directors, a number of
directors equal to the number of the class whose term expires at the meeting
shall be elected to hold office until the third succeeding annual meeting.
Directors shall hold office until the next election of the class for which such
directors shall have been chosen and until their successors are elected and
qualified, except in the case of the death, resignation or removal of any
Director.  Directors need not be shareholders of the Corporation.  The size of
the

                                      -7-

 
Board of Directors shall be within the range of five to nine directors, with the
exact size to be fixed from time to time by resolution of the Board of
Directors.

     Section 3.3  Vacancies.  The shareholders may, at any meeting called for
                  ---------                                                  
such purpose, by a vote of a majority of the capital stock issued and
outstanding and entitled to vote thereon, remove any Director from office, with
or without cause.  Any Director may resign by written notice to the President,
such resignation to be effective upon its receipt by the President or at such
subsequent time as may be specified in the notice of resignation.  Subject to
the rights of the holders of any series of Preferred Stock then outstanding,
newly created directorships resulting from any increase in the authorized number
of Directors or any vacancies in the Board of Directors resulting from death,
resignation, retirement, disqualification or other cause may be filled only by a
majority vote of the directors then in office, though less than a quorum, and
Directors so chosen shall hold office for a term expiring at the next annual
meeting of shareholders at which the term of office of the class to which they
have been elected expires, except in the case of death, resignation or removal
of any Director.  No decrease in the number of Directors constituting the Board
of Directors shall shorten the term of any incumbent Director.  Acceptance of
resignation shall not be necessary for it to be effective.

     Section 3.4  Meetings of the Board of Directors.  The Board of Directors
                  ----------------------------------                         
shall hold an annual meeting immediately following the annual shareholders
meeting, for the purpose of electing officers and for the transaction of such
other business as may properly come before the meeting.  No notice of such
annual meeting shall be necessary to the newly elected directors in order
legally to constitute the meeting, provided a quorum shall be present, unless
said meeting is held, by a consent of a majority of the Directors of such new
Board, at a time and place other then at the place of holding and immediately
following the annual meeting of shareholders.  Special meetings of the Board of
Directors may be held at any place either within or without the State of
Michigan at any time pursuant to resolution adopted by the Board of Directors or
upon call of the President or any two (2) officers.

     Section 3.5  Notice of Meetings.  Notice of meetings of Directors shall be
                  ------------------                                           
given or waived in the same manner as notice of meetings of shareholders, as
provided in Section 2.4, except that notice of Directors meetings shall be given
not later than two (2) nor more than ten (10) days prior to such meetings.

     Section 3.6  Quorum and Required Vote of Board.  A majority of the total
                  ---------------------------------                          
number of Directors shall constitute a quorum for the transaction of business,
and the act of a majority of the Directors present at any meeting at which a
quorum is present shall be the act of the Board of Directors.  Amendment of
these Bylaws by the Board requires the vote of not less than a majority of the
members of the Board then in office.

                                      -8-

 
     Section 3.7  Telephonic Meetings.  A member of the Board or of a committee
                  -------------------                                          
designated by the Board may participate in a meeting by means of conference
telephone or similar communications equipment by which all persons participating
in the discussion can hear each other.  Participation in a meeting pursuant to
this provision constitutes presence in person at the meeting.

     Section 3.8  Board Action Without Meeting.  If all of the Directors then
                  ----------------------------                               
constituting the Board of Directors of the Corporation or of any committee of
the Board of Directors shall severally and/or collectively consent in writing to
any action to be taken, such action shall have the same effect as though it had
been authorized at a duly called and properly held meeting of the Board of
Directors or such committee.  Such written consent shall be filed with the
minutes of the proceedings of the Board.

     Section 3.9  Committees.  The Board of Directors may, by resolution or
                  ----------                                               
resolutions, passed by a majority of the whole Board of Directors, designate one
or more committees, each committee to consist of two (2) or more of the
Directors of the Corporation, which, to the extent provided in said resolution
or resolutions or in other provisions of these Bylaws, shall have and may
exercise the powers of the Board of Directors in the management of the business
and affairs of the Corporation, and may have the power to authorize the seal of
the Corporation to be affixed to all papers which may require it.  However, such
a committee does not have the power or authority to amend the Bylaws of the
Corporation, fill vacancies on the Board of Directors, or fix compensation of
the Directors serving on the Board of Directors or on a committee; and, unless
the resolution of the Board of Directors creating such committee or the Articles
of Incorporation expressly so provide, such a committee does not have the power
or authority to declare a dividend or to authorize the issuance of stock.  Any
such committee, and each member thereof, shall serve at the pleasure of the

as may be determined from time to time by resolution adopted by the Board of
Directors and each committee shall elect a chairman and secretary if one is not

Directors may be paid their expenses, if any, of attendance at each meeting of
the Board, and may be paid a fixed sum for attendance.  No such payment shall
preclude any Director from serving the Corporation in any other capacity and
receiving compensation therefor.  Members of the committees shall be allowed
similar compensation for attending committee meetings.

     Section 3.11  Presumption of Assent.  A Director of the Corporation who is
                   ---------------------

              ARTICLE VI  INDEMNIFICATION OF OFFICERS, DIRECTORS,
              ----------------------------------------------------
                              EMPLOYEES AND AGENTS
                              --------------------

     Section 6.1  Indemnification of Directors and Officers: Claims by Third
                  ----------------------------------------------------------
Parties.  The Corporation shall, to the fullest extent authorized or permitted
- -------                                                                       
by the MBCA or other applicable law, as the same presently exists or may
hereafter be amended, indemnify a director or officer (the "Indemnitee") who was
or is a party or is threatened to be made a party to a threatened, pending, or
completed action, suit, or proceeding, whether civil, criminal, administrative,
or investigative and whether formal or informal, other than an action by or in
the right of the Corporation, by reason of the fact that he or she is or was a
director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, partner, trustee,
employee, or agent of another foreign or domestic corporation, partnership,
joint venture, trust, or other enterprise, whether for profit or not, against
expenses, including attorneys' fees, judgments, penalties, fines, and amounts
paid in settlement actually and reasonably incurred by him or her in connection
with the action, suit, or proceeding, if the Indemnitee acted in good faith and
in a manner he or she reasonably believed to be in or not opposed to the best
interests of the Corporation or its shareholders, and with respect to a criminal
action or proceeding, if the Indemnitee had no reasonable cause to believe his
or her conduct was unlawful.  The termination of an action, suit or proceeding
by judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, does not, of itself, create a presumption that the Indemnitee
did not act in good faith and in a manner which he or she reasonably believed to
be in or not opposed to the best interests of the Corporation or its
shareholders, and, with respect to a criminal action or proceeding, had
reasonable cause to believe that his or her conduct was unlawful.

     Section 6.2  Indemnification of Directors and Officers: Claims Brought By

- ----------------------------------                                        
extent authorized or permitted by the MBCA or other applicable law, as the same
presently exists or may hereafter be amended, indemnify a director or officer
(the "Indemnitee") who was or is a party to or is threatened to be made a party
to a threatened, pending, or completed action or suit by or in the right of the
Corporation to procure a judgment in its favor by reason of the fact that he or
she is or was a director, officer, employee or agent of the Corporation, or is
or was serving at the request of the Corporation as a director, officer,
partner, trustee, employee, or agent of another foreign or domestic corporation,
partnership, joint venture, trust, or other enterprise, whether for profit or
not, against expenses, including actual and reasonable attorneys' fees, and
amounts paid in settlement incurred by the person in connection with the action
or suit, if the Indemnitee acted in good faith and in a manner the person
reasonably believed to be in or not opposed to the best interests of the
Corporation or its shareholders.  However, indemnification under this Section
shall not be made for a claim, issue, or matter in which the Indemnitee has been
found liable to the Corporation unless and only to the extent that the court in
which the action or suit was brought has determined upon application that,
despite the adjudication of liability but in view of all circumstances of the
case, the Indemnitee is fairly and reasonably entitled to indemnification for
the expenses which the court considers proper.

     Section 6.3  Actions by the Indemnitee.  Notwithstanding the provisions of
                  -------------------------                                    
Sections 6.1 and 6.2, the Corporation shall not indemnify an Indemnitee in
connection with any action, suit, proceeding or claim (or part thereof) brought
or made by such Indemnitee; unless such action, suit, proceeding or claim (or
part thereof) (i) was authorized by the Board of Directors of the Corporation,
or (ii) was brought or made to enforce this Article and such Indemnitee has been
successful in such action, suit, proceeding or claim (or part thereof).

     Section 6.4  Approval of Indemnification.  An indemnification under
                  ---------------------------                           
Sections 6.1 or 6.2 hereof, unless ordered by a court, shall be made by the
Corporation only as authorized in the specific case upon it determination that
indemnification of the Indemnitee is proper in the circumstances because such
Indemnitee has met the applicable standard of conduct set forth in Sections 6.1
and 6.2.  This determination shall be made in any of the following ways:

          (a)  By a majority vote of a quorum of the Board consisting of
Directors who were not parties to the action, suit, or proceeding.

          (b)  If the quorum described in subdivision (a) is not obtainable,
then by a majority vote of it committee of Directors who are not parties to the
action.  The committee shall consist of not less than two (2) disinterested
Directors.

          (c)  By independent legal counsel in a written opinion.

                                     -15-

civil or criminal action, suit, or proceeding described in Section 6.1 or 6.2
above shall be paid by the Corporation in advance of the final disposition of
the action, suit, or proceeding upon receipt of an undertaking by or on behalf
of the Indemnitee to repay the expenses if it is ultimately determined that the
Indemnitee is not entitled to be indemnified by the Corporation.  The
undertaking shall be by unlimited general obligation of the person on whose
behalf advances are made but need not be secured.

     Section 6.6  Partial Indemnification.  If an Indemnitee is entitled to
                  -----------------------                                  
indemnification under Section 6.1 or 6.2 for a portion of expenses including
attorneys' fees, judgments, penalties, fines, and amounts paid in settlement,
but not for the total amount thereof, the Corporation shall indemnify the
Indemnitee for the portion of the expenses, judgments, penalties, fines, or
amounts paid in settlement for which the Indemnitee is entitled to be
indemnified.

     Section 6.7  Indemnification of Employees and Agents.  Any person who is
                  ---------------------------------------                    
not covered by the foregoing provisions of this Article and who is or was an
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise,
may be indemnified to the fullest extent authorized or permitted by the MBCA or
other applicable law, as the same exists or may hereafter be amended, but in the
case of any such amendment, only to the extent such amendment permits the
Corporation to provide broader indemnification rights than before such
amendment, but in any event only to the extent authorized at any time or from
time to time by the Board of Directors.

     Section 6.8  Other Rights of Indemnification.  The indemnification or
                  -------------------------------                         
advancement of expenses provided under Sections 6.1 to 6.7 is not exclusive of
other rights to which a person seeking indemnification or advancement of
expenses may be entitled under the Articles of Incorporation, Bylaws, or a
contractual agreement.  However, the total amount of expenses advanced or
indemnified from all sources combined shall not exceed the amount of actual
expenses incurred by the person seeking indemnification or advancement of
expenses.  The indemnification provided for in Sections 6.1 to 6.7 continues as
to a person who ceases to be a director, officer, employee, or agent and shall
inure to the benefit of the heirs, executors, and administrators of the person.

     Section 6.9  Definitions.  "Other enterprises" shall include employee
                  -----------

                   ------------------------------------------------------
Constituent Corporation.  The definition for "corporation" found in Section 569
- -----------------------                                                        
of the MBCA, as the same exists or may hereafter be amended, is and shall be,
specifically excluded from application to this Article.  The indemnification and
other obligations of the Corporation set forth in this Article shall be binding
upon any resulting or surviving corporation after any merger or consolidation of
the Corporation.  Notwithstanding anything to the contrary contained herein or
in Section 569 of the MBCA, no person shall be entitled to the indemnification
and other rights set forth in this Article for acting as a director or officer
of another corporation prior to such other corporation entering into a merger or
consolidation with the Corporation.

     Section 6.11  Contract With the Corporation.  The right to indemnification
                   -----------------------------                               
conferred in this Article VI shall be deemed to be a contract between the
Corporation and each director or officer who serves in any such capacity at any
time while this Article VI is in effect, and any repeal or modification of any
such law or of this Article VI shall not affect any rights or obligations then
existing with respect to any state of facts then or theretofore existing or any
action, suit or proceeding theretofore or thereafter brought or threatened based
in whole or in part upon any such state of facts.  In the event this Article is
repealed or modified, the Corporation shall give written notice thereof to the
directors and officers and any such repeal or modification shall not be
effective for a period of sixty (60) days after such notice is delivered.

     Section 6.12  Liability Insurance.  The Corporation shall have the power to
                   -------------------                                          
purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the Corporation or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise against any liability asserted against and incurred by such
person in any such capacity or arising out of such person's status as such,
regardless of whether the Corporation would have the power to indemnify such
person against such liability under the provisions of the MBCA.

     Section 6.13  Severability.  Each and every paragraph, sentence, term and
                   ------------                                               
provision of this Article VI shall be considered severable in that, in the event
a court finds any paragraph, sentence, term or provision to be invalid or
unenforceable, the validity and enforceability, operation, or effect of the
remaining paragraphs, sentences, terms, or provisions shall not be affected, and
this

                                     -17-

 
Article VI shall be construed in all respects as if the invalid or unenforceable
matter had been omitted.

     Section 6.14  Enforcement.  If a claim under this Article is not paid in
                   -----------                                               
full by the Corporation within thirty days after a written claim has been
received by the Corporation, the claimant may at any time thereafter bring suit
against the Corporation to recover the unpaid amount of the claim, and, if
successful in whole or in part, the claimant shall be entitled to be paid also
the expense of prosecuting such claim.  It shall be a defense to any such action
(other than an action brought to enforce a claim for expenses incurred in
defending any proceeding in advance of its final disposition where the required
undertaking, if any is required, has been tendered to the Corporation) that the
claimant has not met the standards of conduct which make it permissible under
the MBCA for the Corporation to indemnify the claimant for the amount claimed,
but the burden of proving such defense shall be on the Corporation.  Neither the
failure of the Corporation (including its Board of Directors, a committee
thereof, independent legal counsel, or its shareholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because such claimant has met the
applicable standard of conduct set forth in the MBCA nor an actual determination
by the Corporation (including its Board of Directors, a committee thereof,
independent legal counsel, or its shareholders) that the claimant has not met
applicable standard of conduct, shall be a defense to the action or create a
presumption that the claimant has not met the applicable standard of conduct.

                        ARTICLE VII  EXECUTION OF PAPERS
                        --------------------------------

          The officers of the Corporation may sell any or all of its holdings of
stock, bonds, or securities of other corporations, or government securities;
sign all deeds, mortgages, assignments of mortgages, discharges of mortgages,
bills of sale, leases and other conveyances and transactions of any interest in
property, real, personal or mixed, to the extent that the Board of Directors of
the Corporation may from time to time specify in resolutions approved by the
Board.  The Board may in any instance designate the officers and agents who
shall have authority to execute any contract, conveyance or other instrument on
behalf of the Corporation, and may also ratify and affirm such execution.  Any
such instrument or document shall be binding on the Corporation if executed by
the President or a Vice President.  In addition, any such instrument or document
shall be binding on the Corporation if signed by any other officer designated by
the Board on behalf of the Corporation.

                             ARTICLE VIII  BANKING
                             ---------------------

     Section 8.1  Bank Accounts.  The Board of Directors shall by resolution
                  -------------                                             
designate the bank or banks in which the funds of the Corporation shall be
deposited, and such funds shall be deposited in the name of the Corporation and

                                     -18-

 
shall be subject to checks drawn as authorized by resolution of the Board of
Directors.

     Section 8.2  Borrowing.  To the extent authorized by law, the Corporation
                  ---------                                                   
may, wherever its general interests and corporate purpose require the same,
borrow money and issue its promissory notes, debentures or bonds for the
repayment thereof with interest, and may in like case mortgage, pledge or
encumber its property as security for its debts or other lawful engagements.

                 ARTICLE IX  VOTING STOCK IN OTHER CORPORATIONS
                 ----------------------------------------------

          Unless otherwise ordered by the Board of Directors, the President
shall have full power and authority on behalf of the Corporation to attend and
to act and to vote at any meetings of shareholders of any corporation in which
this Corporation may hold stock, and at any such meeting shall possess and may
exercise any and all of the rights and powers incident to the ownership of such
stock, PROVIDED, HOWEVER, that such rights shall be exercised in the best
interests of this Corporation.  The Board of Directors may, by resolution, from
time to time confer like powers upon any other person or persons, but the same
shall not be effective unless actually received by such other corporation prior
to the meeting of shareholders in which such other person is to act.  The
President, or in his absence or disability, a Vice President of the Corporation,
may authorize from time to time the signature and issuance of proxies to vote
such stock of other corporations owned by this Corporation, and all such proxies
shall be signed in the name of this Corporation by the President or Vice

          The Board of Directors may establish, reorganize and/or dissolve
wholly- or partly-owned subsidiaries of the Corporation.  The Articles of
Incorporation and Bylaws of any such subsidiary shall not, without approval of
the shareholders of this Corporation, substantially differ from the Articles of
Incorporation and Bylaws, respectively, of this Corporation.

                             ARTICLE XI FISCAL YEAR
                             ----------------------

Directors, the fiscal year of the Corporation shall end on the last day of June.

                    ARTICLE XII  CORPORATE BOOKS AND RECORDS
                    ----------------------------------------

          The Corporation shall keep books and records of account and minutes of
the proceedings of its shareholders, Board of Directors and executive
committees, if any.  The books, records and minutes may be kept outside this
state.  The Corporation shall keep at its registered office, or at the office of
its

          Except as otherwise expressly provided in the Articles of
Incorporation or in these Bylaws, these Bylaws may be altered, amended or
repealed by any duly adopted resolution of the Board of Directors or at any
annual or special meeting of the shareholders.  The Board of Directors, however,
shall not adopt or alter any Bylaws fixing the number, qualifications,
classifications or term of office of Directors.  If the amendment is to be
adopted at a special meeting of the shareholders, the notice thereof shall
specify the subject matter of the proposed alteration, amendment or repeal and
the Articles of these Bylaws to be affected thereby.  Bylaws adopted by the
Directors may be altered or repealed by the Directors or shareholders.
Provided, further, that neither the time nor the place for the election of
Directors shall be changed within sixty (60) days next preceding the day on
which any election of Directors is to be held, and provided further that a
notice of any such change shall be given to each shareholder at least twenty
(20) days before the next election is held, in person or by letter mailed to his

ii. AASTROM BIOSCIENCES, INC. AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT THIS AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT (the "Agreement") is entered into as of April 7, 1992, by and among AASTROM BioSciences, Inc., a Michigan corporation formerly doing business as Ann Arbor Stromal, Inc.

Emerson, Bernhard O. Palsson and Michael F. Clarke (individually, a "Founder" and collectively, the "Founders"), Dr. R. Douglas Armstrong ("Armstrong") and the Regents of the University of Michigan, a constitutional corporation of the State of Michigan (the "University"). For the purposes of this Agreement, the Founders and Armstrong shall be collectively referred to as the "Option Holders." RECITALS: -------- A. The Company has issued shares of its Common Stock to the University and has granted, and may, in the future, grant, stock options to the Founders pursuant to the Company's Stock Option Plans. B. The Company has issued two million five hundred thousand (2,500,000) shares of its Series A Preferred Stock to certain of the Investors (the "Series A Investors") pursuant to that certain Series A Preferred Stock Purchase Agreement, dated as of August 17, 1989. C. Pursuant to that certain Investors' Rights Agreement dated August 17, 1989 among the Company, the Series A Investors, the Founders and the University (the "Investors' Rights Agreement"), the Company granted certain rights and the parties made certain covenants with respect to the Series A Preferred Stock and the Common Stock of the Company. D. Since the execution of the Investors' Rights Agreement, the Company has engaged Armstrong as its president and has granted, and may, in the future, grant, stock options to Armstrong pursuant to the Company's Stock Option Plans. E. Certain of the Investors (the "Series B Investors") are purchasing concurrently herewith three million thirty thousand (3,030,000) shares of Series B Preferred Stock and desire to obtain the same rights as are contained in the Investors' Rights Agreement. F. The Company, the Series A Investors, the Founders and the University desire to grant to the Series B Investors and 1 Armstrong the same rights as were granted under the Investors' Rights Agreement and to amend and restate such Agreement. G. The parties intend that this Agreement supersede the Investors' Rights Agreement and, in that regard, the parties to the Investors' Rights Agreement will waive certain rights contained in such Investors' Rights Agreement, specifically (i) the right of first refusal to purchase on a pro rata basis the shares of Series B Preferred Stock being issued concurrently herewith and (ii) the right of the University to obtain certain warrants to purchase Common Stock.

Each such notice shall describe the manner and circumstances of the proposed transfer in sufficient detail, and shall be accompanied (except in the following cases, with respect to which the requirements set forth in the balance of this sentence need not be complied with: transactions in compliance with Rule 144 so long as the Company is furnished with evidence of compliance with such Rule, including without limitation, an opinion of counsel to such effect; transactions involving the pro rata distribution of Restricted Securities by any holder which is a general or limited partnership to any of its partners, or retired partners, or to the estate of any of its partners or retired partners; transactions involving the transfer of Restricted Securities by any holder who is an individual to his family members or to a trust for the benefit of such holder or his family members; or transfers not involving a change in beneficial ownership) by which the requirements set forth in the balance of this sentence need not be complied with: transactions in compliance with Rule 144 so long as the Company is furnished with evidence of compliance with such Rule, including without limitation, an opinion of counsel to such effect; transactions involving the pro rata distribution of Restricted Securities by any holder which is a general or limited partnership to any of its partners, or retired partners, or to the estate of any of its partners or retired partners; transactions involving the transfer of Restricted Securities by any holder who is an individual to his family members or to a trust for the benefit of such holder or his family members; or transfers not involving a change in beneficial ownership) by 5 either (i) an unqualified written opinion of legal counsel who shall be reasonably satisfactory to the Company addressed to the Company and reasonably satisfactory in form and substance to the Company's counsel, to the effect that the proposed transfer of the Restricted Securities may be effected without registration under the Securities Act, (ii) a "no action" letter from the Commission to the effect that the distribution of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, or (iii) such other showing that may be reasonably satisfactory to legal counsel to the Company, whereupon the holder of such Restricted Securities shall be entitled to transfer such Restricted Securities in accordance with the terms of the notice delivered by the holder to the Company. Each certificate evidencing the Restricted Securities transferred as above provided shall bear the appropriate restrictive legend set forth in Section 2.2 above, except that such certificate shall not bear such restrictive legend if in the opinion of counsel for the Company such legend is not required in order to establish compliance with any provisions of the Securities Act. 2.4 Requested Registration. ---------------------- (a) Request for Registration. In case the Company shall receive from ------------------------ Initiating Holders after the first anniversary of the Company's initial public offering, or after January 1, 1994, whichever shall occur first, a written request that the Company effect any registration (other than a registration on Form S-3 or any related form of Registration Statement) covering the registration of at least twenty percent (20%) of their Registrable Securities (or a lesser percentage if the anticipated aggregate offering price net of underwriting discounts and commissions, would exceed $2,000,000), the Company will: (i) promptly give written notice of the proposed registration to all other Holders; and (ii) as soon as practicable, use its diligent best efforts to effect such registration (including, without limitation, the execution of an undertaking to file post-effective amendments, appropriate qualification under applicable blue sky or other state securities laws and appropriate compliance with applicable regulations issued under the Securities Act) as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company; provided that prior to the Company's initial public offering, no Initiating Holder may make a written request that the Company effect any registration 6 unless the aggregate anticipated offering price would exceed, net of underwriting discounts and commissions, $5,000,000; and provided further that the Company shall not be obligated to take any action to effect any such registration, qualification or compliance pursuant to this Section 2.4: (A) In any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, qualification or compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; or (B) During the period starting with the date sixty (60) days prior to the Company's estimated date of filing of, and ending on a date six (6) months following the effective date of, a registration statement pertaining to an underwritten public offering of securities filed for the account of the Company (other than a registration relating solely to employee benefit plans or a registration relating solely to a Commission Rule 145 transaction), provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective and the Company's estimate of the date of filing such registration statement is made in good faith; or (C) After the Company has effected one registration pursuant to this Section 2.4 and such registration has been declared or ordered effective. Subject to the foregoing clauses (A), (B) and (C) and to Section 2.4(c), the Company shall file a registration statement covering the Registrable Securities so requested to be registered as soon as practicable after receipt of the request of the Initiating Holders.

The right of any Holder to registration pursuant to Section 2.4 shall be conditioned upon such Holder's participation in such underwriting and the inclusion of such Holder's Registrable Securities in the underwriting to the extent requested (unless otherwise mutually agreed by a majority in interest of the Holders and such Holder) to the extent provided herein. The Company shall (together with all Holders proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the underwriter or underwriters of recognized national standing selected for such underwriting by the Company with the 7 approval of a majority in interest of the participating Holders. Notwithstanding any other provision of this Section 2.4, if the underwriter determines that marketing factors require a limitation of the number of shares to be underwritten or that applicable state law prohibits the registration of any Holders' Registrable Securities because of the failure or lack of obligation of such Holder to contribute to the cost of such registration and so advises the participating Holders in writing, then the Company shall so advise all Holders (except those Holders who have indicated to the Company their decision not to distribute any of their Registrable Securities through such underwriting) and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among all such Holders in proportion, as nearly as practicable, to the respective amounts of Registrable Securities owned by such Holders at the time of filing the registration statement. No Registrable Securities excluded from the underwriting by reason of the underwriter's marketing limitation or such state law shall be included in such registration. If any Holder disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company, the underwriter and the other Holders. The Registrable Securities and/or other securities so withdrawn from such underwriting shall also be withdrawn from such registration; provided, however, that, if by the withdrawal of such Registrable Securities a greater number of Registrable Securities held by other Holders may be included in such registration (up to the maximum of any limitation imposed by the underwriters), then the Company shall offer to all Holders who have included Registrable Securities in the registration the right to include additional Registrable Securities in the same proportion used above in determining the underwriter limitation. If the underwriter has not limited the number of Registrable Securities to be underwritten, the Company may include securities for its own account or the account of others in such registration if the underwriter so agrees and if the number of Registrable Securities which would otherwise have been included in such registration and underwriting will not thereby be limited. (c) Delay of Registration. If the Company shall furnish to the --------------------- Holders a certificate signed by the President of the Company stating that, in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its shareholders for such registration statement to be filed on or before the date filing would be required and it is therefore essential to defer the filing of such registration statement, then the Company may direct that such request for registration be delayed not in excess of one hundred 8 and fifty (150) days, such right to delay a request to be exercised by the Company not more than twice in any one-year period. 2.5 Company Registration. -------------------- (a) If at any time or from time to time, the Company shall determine to register any of its Common Stock, for its own account or for the account of others (other than the Holders), other than a registration relating solely to employee benefit plans or a registration relating solely to a Commission Rule 145 transaction or a registration on any registration form which does not include substantially the same information as would be required to be included in a registration statement covering the sale of Registrable Securities, the Company will: (i) promptly give to each Holder written notice thereof (which shall include a list of the jurisdictions in which the Company intends to attempt to qualify such securities under the applicable blue sky or other state securities laws); and (ii) include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the Registrable Securities specified in a written request or requests, made within twenty (20) days after receipt of such written notice from the Company, by any Holder or Holders. The rights of a particular Holder under this Section 2.5 shall terminate five (5) years after the effective date of the Company's initial underwritten public offering. (b) Underwriting. If the registration of which the Company gives ------------ notice is for a registered public offering involving an underwriting, the Company shall so advise the Holders as a part of the written notice given pursuant to Section 2.5(a)(i). In such event the right of any Holder to registration pursuant to Section 2.5 shall be conditioned upon such Holder's participation in such underwriting and the inclusion of such Holder's Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company and the other holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. Notwithstanding any other provision of this Section 2.5, if the underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the underwriter may exclude some or all Registrable Securities from such registration and underwriting. The Company shall so advise 9 all Holders (except those Holders who have indicated to the Company their decision not to distribute any of their Registrable Securities through such underwriting), and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among such Holders in proportion, as nearly as practicable, to the respective amounts of Registrable Securities owned by such Holders at the time of filing the registration statement. No Registrable Securities excluded from the underwriting by reason of the underwriter's marketing limitation shall be included in such registration. If any Holder disapproves of the terms of any such underwriting, such person may elect to withdraw therefrom by written notice to the Company and the underwriter. The Registrable Securities and/or other securities so withdrawn from such underwriting shall also be withdrawn from such registration; provided, however, that, if by the withdrawal of such Registrable Securities a greater number of Registrable Securities held by other Holders may be included in such registration (up to the maximum of any limitation imposed by the underwriters), then the Company shall offer to all Holders who have included Registrable Securities in the registration the right to include additional Registrable Securities in the same proportion used above in determining the underwriter limitation. 2.6 Registrations on Form S-3. ------------------------- (a) If (i) Holders of Registrable Securities request in writing (specifying that the request is being made pursuant to this Section 2.6) that the Company file a registration statement on Form S-3 (or any successor form to Form S-3 regardless of its designation) for a public offering of shares of Registrable Securities the reasonably anticipated aggregate proceeds of which would exceed $500,000, and (ii) the Company is a registrant entitled to use Form S-3 to register such shares, and (iii) the Company has not filed a registration statement pursuant to this Section 2.6 within the twelve (12) months immediately prior to the requested filing date, then the Company shall cause such shares, and any additional shares included pursuant to Section 2.6(b), to be registered on Form S-3 (or any successor form to Form S-3). (b) Prior to effecting a registration of Registrable Securities pursuant to Section 2.6(a), the Company shall (i) give to each Holder written notice of the intended registration and (ii) include in such registration any additional Registrable Securities specified in any written request or requests by additional Holders received within fifteen (15) days after such written notice is given. 10 (c) All expenses incurred in connection with any registrations requested pursuant to this Section 2.6 including, without limitation, all registration, qualification, printing, and accounting fees, and fees and disbursements of counsel for the Company, shall be borne by the Holder or Holders participating in such registration on the basis of the amount of securities so registered. (d) The Holders' rights to registration under this Section 2.6 are in addition to, and not in lieu of, their rights to registration under Sections 2.4 and 2.5. 2.7 Expenses of Registration. ------------------------ (a) All Registration Expenses (exclusive of underwriting discounts and commissions and more than a single special counsel to the selling shareholders) incurred in connection with the first registration pursuant to Section 2.4 shall be borne by the Company. The Company shall not, however, be required to pay for expenses of any registration proceeding begun pursuant to Section 2.4, the request of which has been subsequently withdrawn by the Initiating Holders (unless the withdrawal is based upon material adverse information concerning the Company of which the Initiating Holders were not aware at the time of such request and the Holders of a majority of Registrable Securities agree to forfeit their right to one requested registration pursuant to Section 2.4 in which event such right shall be forfeited by all Holders), in which case such expenses shall be borne by the holders of securities (including Registrable Securities) requesting such registration in proportion to the number of shares for which registration was requested and such registration shall not be counted as a registration pursuant to Section 2.4 for purposes of Section 2.4(a)(ii)(B). (b) All Registration Expenses (exclusive of underwriting discounts and commissions and more than a single special counsel to the selling shareholders) incurred in connection with the first two registrations pursuant to Section 2.5 shall be borne by the Company. In each subsequent registration of Registrable Securities effected pursuant to Section 2.5, the Holders who include Registrable Securities in such registration shall bear any additional registration and qualification fees and expenses (including underwriters' discounts and commissions), and any additional costs and disbursements of counsel for the Company that result from the inclusion of the Registrable Securities in such registration, with such additional expenses of the registration being borne by all such Holders pro rata on the basis of the amount of Registrable Securities so registered; provided, however, that if any such cost or expense is attributable solely to one selling Holder and does not constitute a normal cost or expense of such a 11 registration, such cost or expense shall be allocated to that selling Holder. In addition, each selling Holder shall bear the fees and costs of its own counsel. 2.8 Registration Procedures. In the case of each registration, ----------------------- qualification or compliance effected by the Company pursuant to this Section 2, the Company will keep each Holder advised in writing as to the initiation of each registration, qualification and compliance and as to the completion thereof. At its expense the Company will: (a) Keep such registration, qualification or compliance effective for a period of one hundred and twenty (120) days or until the Holder or Holders have completed the distribution described in the registration statement relating thereto, whichever first occurs; and (b) Furnish such number of prospectuses and other documents incident thereto as a Holder from time to time may reasonably request. 2.9 Indemnification. --------------- (a) The Company will indemnify each Holder, each of its officers, directors, employees, agents, partners and legal counsel, and each person controlling such Holder, with respect to which registration, qualification or compliance has been effected pursuant to this Section 2, and each underwriter, if any, and each person who controls any underwriter against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on (i) any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular or other similar document (including any related registration statement, notification or the like) incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to skate therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made, or (ii) any violation by the Company of any federal, state or common law rule or regulation applicable to the Company in connection with any such registration, qualification or compliance, and will reimburse each such Holder, each of its officers, directors, employees, agents, partners and legal counsel, and each person controlling such Holder, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, as incurred, provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission based upon written information furnished to the Company 12 by an instrument duly executed by such Holder or underwriter and specifically for use therein. (b) Each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Company, each of its directors, officers, employees and agents each legal counsel and independent accountant of the Company, each underwriter, if any, of the Company's securities covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of the Securities Act, and each other such Holder, each of its officers, directors, and partners and each person controlling such Holder, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other similar document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made, and will reimburse the Company, such Holders, such directors, officers, employees, agents, persons, underwriters or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, as incurred, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder and specifically for use therein; provided, however, that the obligations of such Holders hereunder shall be limited to an amount equal to the proceeds to each such Holder of Registrable Securities sold as contemplated herein. (c) Each party entitled to indemnification under this Section 2.9 (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has received written notice of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld). The Indemnified Party may participate in such defense at such party's expense; provided, however, that the Indemnifying Party shall bear the expense of such defense of the Indemnified Party if representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of 13 interest. The failure of any Indemnified Party to give notice as provided herein shall relieve the Indemnifying Party of its obligations under this Section 2 only to the extent that such failure to give notice shall materially adversely prejudice the Indemnifying Party in the defense of any such claim or any such litigation. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation (without any obligation of performance or admission by the Indemnified Party). (d) Notwithstanding anything contained in this Section 2.9 to the contrary, the Company shall have the right and the ability to provide the necessary undertakings to the Commission in connection with any registration. 2.10 Information by Holder. The Holder or Holders of Registrable --------------------- Securities included in any registration shall furnish to the Company such information regarding such Holder or Holders and the distribution proposed by such Holder or Holders as the Company may request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Section 2. 2.11 Rule 144 Reporting. With a view to making available the benefits of ------------------ certain rules and regulations of the Commission which may at any time permit the sale of the Restricted Securities to the public without registration, after such time as a public market exists for the Common Stock of the Company, the Company agrees to: (a) Use its best efforts to facilitate the sale of the Restricted Securities to the public, without registration under the Securities Act, pursuant to Rule 144 under the Securities Act, provided that this shall not require the Company to file reports under the Securities Act and the Exchange Act at any time prior to the Company's being otherwise required to file such reports. (b) Use its best efforts to make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act at all times after ninety (90) days after the effective date of the first registration under the Securities Act filed by the Company for an offering of its securities to the general public; (c) Use its best efforts to then file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange 14 Act, as amended (at any time after it has become subject to such reporting requirements); (d) So long as any Holder holds any Restricted Securities to furnish to the Holder forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement filed by the Company for an offering of its securities to the general public), and of the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as a Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing a Holder to sell any such securities without registration. 2.12 "Market Stand-off" Agreement. Each Holder of more than one percent --------------------------- (1%) of the Company's outstanding voting stock agrees not to sell or otherwise transfer or dispose of any Common Stock (or other securities) of the Company held by it during the one hundred fifty (150) day period following the effective date of a registration statement of the Company filed under the Securities Act if so requested by the Company and underwriter of Common Stock (or other securities) of the Company, provided that: (a) such agreement shall apply only to the first underwritten registered public offering of the Company; and (b) all officers and directors of the Company and all other holders of at least one percent (1%) of the Company's voting securities enter into similar agreements. The Company may impose stop-transfer instructions with respect to the shares (or securities) subject to the foregoing restriction until the end of such period. 2.13 Transfer of Registration Rights. The rights to cause the Company to ------------------------------- register securities granted under this Section 2 may be assigned or otherwise conveyed by (i) any Holder (other than an Option Holder) only to a transferee or assignee in a private transaction to whom not less than 100,000 shares of Registrable Securities are conveyed (as presently constituted and subject to subsequent adjustments for stock splits, stock dividends, reverse stock splits, and the like) or (ii) an Option Holder in the manner set forth above or otherwise only to another Holder or to a family member or to a trust for the benefit of such Option Holder or family members in a private transaction to whom not less than 20,000 shares of Registrable Securities are conveyed (as presently constituted and subject to subsequent adjustments as set forth above); provided that the Company is given written notice by such transferee at the time of or within 15 a reasonable time after said transfer, stating the name and address of said transferee and said transferee's agreement to be bound by the provisions of this Agreement. 2.14 Suspension of Registration Rights. The registration rights granted --------------------------------- pursuant to this Section 2 shall not be exercisable by any Holder during the period in which such Holder has the ability to sell all of the Shares held by such Holder under Rule 144 or Rule 144A during a single ninety (90) day period. 2.15 Certain Limitations in Connection with Future Grants of Registration -------------------------------------------------------------------- Rights. From and after the date of this Agreement, the Company shall not enter - ------ into any agreement with any holder or prospective holder of any securities of the Company providing for the granting to such holder of registration rights unless such agreement: (a) includes the equivalent of Section 2.12 as a term; and (b) contains provisions substantially similar to those contained in Sections 2.4(b) and 2.5(b) with respect to the allocation of Registrable Securities to be included in an underwritten public offering if marketing factors require a limitation on the number of such securities to be included. Notwithstanding the foregoing, from and after the date hereof the Company shall not enter into any agreement with any person or persons providing for the granting to such holder registration rights superior to those granted to Holders pursuant to this Section 2, or of registration rights which might cause a reduction in the number of shares includable by the Holders in any offering pursuant to Section 2.4 or in any offering subject to Section 2.5. SECTION 3 Affirmative Covenants --------------------- Notwithstanding any provision of the Company's Bylaws regarding delivery or non-delivery of financial information to shareholders of the Company, the Company hereby covenants and agrees as follows: 3.1 Financial Information. The Company will furnish the following --------------------- information to each Holder (other than the Option Holders) for so long as it is a holder of any Shares or Common Stock issued upon conversion thereof, or of 450,000 shares or more of Common Stock: 16 (a) As soon as practicable after the end of each fiscal year, and in any event within one hundred and twenty (120) days thereafter, a consolidated balance sheet of the Company and its subsidiaries, if any, as of the end of such fiscal year, and consolidated statements of income, shareholders' equity and cash flows of the Company and its subsidiaries, if any, for such year, prepared in accordance with generally accepted accounting principles and setting forth in each case in comparative form the figures for the previous fiscal year, all in reasonable detail and with an audit opinion thereon from independent public accountants of recognized national standing selected by the Company.

SECTION 4 Right of First Refusal ---------------------- 4.1 Right of First Refusal. The Company hereby grants to each Holder ---------------------- the right of first refusal to purchase, pro rata, New Securities that the Company may, from time to time, propose to sell and issue. Each Holder's pro rata share, for purposes of this right of first refusal, is the ratio of the number of 19 shares of Common Stock (and shares of Common Stock issuable upon conversion of securities convertible into shares of Common Stock), excluding the number of shares of Common Stock which may be issued upon exercise of any Option, actually held by such Holder, to the total number of outstanding shares of Common Stock (calculated on a fully diluted basis) of the Company. This right of first refusal shall be subject to the following provisions: (a) In the event that the Company proposes to undertake an issuance of New Securities, it shall give each Holder written notice of its intention, describing the type of New Securities, the price, and the general terms upon which the Company proposes to issue the same. Each Holder shall have ten (10) business days from the date of receipt of any such notice to agree to purchase its pro rata share of such New Securities for the price and upon the general terms specified in the notice by giving written notice to the Company and stating therein the quantity of New Securities to be purchased. Each Holder shall have a right of over allotment such that if any Holder fails to exercise its right hereunder to purchase its pro rata portion of New Securities, the Company shall so notify the other Holders and the other Holders may purchase the non-purchasing Holder's portion on a pro rata basis, within ten (10) days from the date of such notice. (b) In the event that a Holder fails to exercise in full the right of first refusal within said ten (10) day period (plus ten (10) day period, if applicable) the Company shall have ninety (90) days thereafter to sell the New Securities respecting which the Holders' rights were not exercised, at a price and upon general terms no more favorable to the purchasers thereof than specified in the Company's notice. In the event the Company has not sold the New Securities within such ninety (90) day period, the Company shall not thereafter issue or sell any New Securities, without first offering such securities to the Holders in the manner provided above. (c) The right of first refusal granted under this Agreement shall expire upon the closing of the first firmly underwritten public offering of Common Stock of the Company pursuant to a registration statement filed with, and declared effective by, the Commission under the Securities Act, covering the offer and sale of Common Stock to the public at a per-share price (prior to underwriters' commissions and expenses) of at least $5.00 (as adjusted for any combinations, consolidations, stock distributions or stock dividends with the respect to such stock) and at an aggregate offering price of not less than $10,000,000. (d) This right of first refusal is assignable only in connection with a sale of Shares or Common Stock issued on conversion thereof. 20 4.2 Waiver. The Series A Investors, the Founders and the University ------ each hereby waive their respective rights under Section 4.1 of the Investors' Rights Agreement to purchase their pro rata share of the Series B Preferred Stock being issued to the Series B Investors pursuant to that certain Series B Preferred Stock Purchase Agreement of even date herewith (the "Series B Agreement").

The parties hereto further agree that this Agreement constitutes the full and entire understanding and agreement between the parties with regard to the subjects hereof and thereof, except that no provision, condition or term of this Agreement, including but not limited to Section 6.8 below, is intended to explicitly or implicitly alter or allow to be altered any provision, condition or term of the UM-Ann Arbor Stromal Agreement. 6.2 Governing Law. This agreement shall be governed by and construed ------------- in accordance with the laws of the State of Michigan applicable to contracts between Michigan residents entered into and to be performed entirely within the State of Michigan. 6.3 Successors and Assigns. Except as otherwise provided herein, the ---------------------- provisions hereof shall inure to the benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto. 6.4 Notices. All notices and other communications required or ------- permitted hereunder shall be in writing and shall be effective five (5) days after mailed by first-class mail, postage prepaid, 21 or otherwise delivered by hand or by messenger, addressed (a) if to an Investor at such Investor's address set forth on Exhibit A, or at such other address as such Investor shall have furnished to the Company in writing, or (b) if to any other Holder, at such address as such Holder shall have furnished the Company in writing, or, until any such Holder so furnishes an address to the Company, then to and at the address of the last holder of such Registerable Securities who has so furnished an address to the Company, or (c) if to the Company, at such address as the Company shall have furnished to each Holder in writing. 6.5 Delays or Omissions. No delay or omission to exercise any right, ------------------- power or remedy accruing to any holder of any Registerable Securities, upon any breach or default of the Company under this Agreement, shall impair any such right, power or remedy of such Holder nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereunder occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any holder of any breach or default under this Agreement, or any waiver on the part of any holder of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this agreement, or by law or otherwise afforded to any Holder, shall be cumulative and not alternative. 6.6 Counterparts. This Agreement may be executed in any number of ------------ counterparts, each of which may be executed by less than all of the Holders, each of which shall be enforceable against the parties actually executing such counterparts, and all of which together shall constitute one instrument. 6.7 Severability. In the case any provision of this Agreement shall ------------ be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 6.8 Amendments.

At all times during ---------------------------------------------- the term of my service as a director and thereafter, I will hold in strictest confidence and will not disclose or use any of the Company's Proprietary Information (defined below), except as such disclosure or use may be required in connection with my work for the Company, or unless an officer of the Company expressly authorizes such disclosure or use. I assign to the Company any rights I may have or acquire in such Proprietary information and recognize that all Proprietary information shall be the sole property for the Company and its successors and assigns, and the Company and its successors and assigns shall be the sole owner of all patents, copyrights, and other rights in connection therewith. The term "Proprietary Information" shall mean all of the confidential or proprietary information of the Company, including, but not limited to: a. inventions, trade secrets, ideas, processes, formulas, source codes, data, programs, other original works or authorship, know-how, improvements, discoveries, developments, designs and techniques, (hereinafter collectively referred to as "Inventions"); and b. plans for research, development, new products, marketing and selling; financial statements; licenses; prices and costs; information concerning suppliers and customers; and information regarding the skills and compensations of employees of the Company. Notwithstanding the foregoing, Proprietary information shall not include: --------- a. information which at the time of disclosure to the undersigned is in the public domain, b. information which was received by the undersigned from a third party having the legal right to transmit the same to the undersigned, or c. information which was independently developed by the undersigned without reliance on any information received from the Company.

Assignment of Proprietary Rights. I hereby assign to the Company and -------------------------------- its successors and assigns all my right, title and interest in and to any and all inventions whether or not patentable or registrable under copyright or similar statutes, made or conceived or reduced to practice or learned by me, either alone or jointly with others, during the term of my service as a director with the Company.

Inventions assigned to or as directed by the Company by this paragraph 2 are hereinafter referred to as "Company Inventions." Provided however, the foregoing assignment of inventions applies only to inventions related to the technology and business of the Company, but not to any --- other inventions which I may make independent from my service with the Company, or that I may make as part of a formalized collaboration with the Company that is outside of my role as a director (any such collaboration being established and mutually agreed to in writing). 3. Enforcement of Proprietary Rights. I will assist the Company in --------------------------------- every proper way to obtain and from time to time enforce United States and foreign patents, copyright and other rights and protections relating to Company inventions in any and all countries. To that end I will execute, verify and deliver such documents and perform such other acts (including appearances as a witness) as the Company may reasonably request for use in applying for, obtaining, sustaining and enforcing such patents, copyrights and other rights and protections on Company inventions. In addition, I will execute, verify and deliver assignments of such patents, copyrights, and other rights and protections to the Company or its designee. My obligation to assist the Company in obtaining and enforcing patents, copyrights, and other rights and protections relating to such Company Inventions in any and all countries shall continue beyond the termination of my service as a director, but the Company shall compensate me at a reasonable -2- rate after my termination for the time actually spent by me at the Company's request on such assistance. In the event the Company is unable, after reasonable effort, to secure my signature on any document needed to apply for or prosecute any patent, copyright, or other right or protection relating to a Company Invention, I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact, to act for an in my behalf to execute, verify and file any such applications and to do all other lawfully permitted acts to further the prosecution and issuance of patents, copyrights, and other rights and protections thereon with the same legal force and effect as if executed by me. 4.

I agree that any patent application filed within a year after termination of my service as a director shall be presumed to relate to an invention made during the term of my service as a director unless I can sustain the burden of proving the contrary. 5. Prior Inventions. Inventions if any, patented or unpatented, which I ---------------- made prior to the commencement of my service as a director with the Company, are excluded from the scope of this Agreement. To preclude any possible uncertainty, I have set forth on Exhibit A attached hereto, a complete list of all inventions that I have, alone or jointly with other, conceived, developed or reduced to practice or caused to be conceived, developed, or reduced to practice, prior to the commencement of my service as a director with the Company, that I consider to not be Company property and that I wish to have excluded from the scope of this Agreement. 6. No Improper Use of Materials. During my service as a director at the ---------------------------- Company, I will not improperly use or disclose any confidential information or trade secrets, if any, of any former or current employer, and I will not bring onto the premises of the Company any unpublished documents or any property belonging to any former or current employer unless consented to in writing by that employer. 7. No Conflicting Obligation. I represent that my performance of all ------------------------- terms of this Agreement and as a director of the Company does not and will not breach any agreement to keep in confidence information acquired by me in confidence or in trust prior to my service as a director by the Company. I have not -3- entered into, and I agree I will not enter into, any agreement either written or oral in conflict herewith. 8. Effect of Termination. Upon the termination of my service as a --------------------- director with the Company, I understand that the Company and I shall be released from all obligations and liabilities to the other occurring or arising after the date of such termination, except that any termination of my service as a director with the Company shall not relieve me of my obligations under Sections 1, 2, 3, 4, and 6 hereof, nor shall any such termination relieve me or the Company from any liability arising from any breach of the provisions contained herein.

Legal and Equitable Remedies. Because my services are personal and ---------------------------- unique and because I may have access to and become acquainted with the Proprietary Information of the Company, the Company shall have the right to enforce this Agreement and any of its provisions by injunction, specific performance or other equitable relief without prejudice to any other rights and remedies that the Company may have for a breach of this Agreement. 10. Notices. Any notices required or permitted hereunder shall be given ------- to the appropriate party at the address specified below or at such other address as the party shall specify in writing.

                                                                    EXHIBIT 10.1

                           INDEMNIFICATION AGREEMENT


     This Agreement is made as of __________, between Aastrom Biosciences, Inc.,
a Michigan corporation (the "Company"), and those certain officers and directors
of the Company designated on the signature page of this Agreement as Indemnitees
(hereinafter referred to individually as an "Indemnitee" and collectively as the
"Indemnitees").

                                    RECITALS

          A.  It is essential to the Company to attract and retain as directors
and officers the most capable persons available.

          B.  Both the Company and Indemnitees recognize the increased risk of
litigation and other claims being asserted against directors and officers of
companies in today's environment.

          C.  While basic protection against undue risk of personal liability of
directors and officers may be provided through insurance coverage, it has become
increasingly difficult to obtain such insurance on terms providing reasonable
protection at reasonable cost.
 
          D.  The Restated Articles of Incorporation and the Bylaws of the
Company permit the Company to indemnify and advance expenses to its directors
and officers to the full extent permitted by law; and Indemnitees have been
serving and continue to serve as directors and officers of the Company in part
in reliance on such Restated Articles of Incorporation and Bylaws.

          E.  In recognition of Indemnitees' need for substantial protection
against personal liability, the increasing difficulty in obtaining satisfactory
insurance coverage, and Indemnitees' reliance on the aforesaid Restated Articles
of Incorporation and Bylaws, and in part to provide Indemnitees with specific
contractual assurance that the protection promised by the Restated Articles of
Incorporation and Bylaws will be available to Indemnitees (regardless of, among
other things, any amendment to or revocation of such Restated Articles of
Incorporation or Bylaws or any change in the composition of the Company's Board
of Directors), the Company wishes to provide in this Agreement for the
indemnification of and the advancing of expenses to Indemnitees to the fullest
extent permitted by law and as set forth in this Agreement, and, to the extent
insurance coverage is maintained, for the continued coverage of Indemnitees
under the Company's directors' and officers', liability insurance policies.

     NOW, THEREFORE, in consideration of Indemnitees' service to the

 
Company, or Indemnitees' service to another enterprise at the request of the
Company, the parties hereto agree as follows:

          1.  Certain Definitions.  As used herein, the following terms shall
              -------------------
refer to the following events or have the following meanings, as the case may
be:

               a.  Change in Control is an event which shall be deemed to have
                   -----------------
occurred if any one or more of the following events occur: (i) any "person" (as
such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of
1934, as amended) hereafter becomes the "beneficial owner" (as defined in Rule
13d-3 under said Act), directly or indirectly, of securities of the Company
representing twenty percent or more of the total voting power represented by the
Company's then outstanding Voting Securities, excluding, however, a trustee or
other fiduciary holding securities under an employee benefit plan of the Company
or a corporation owned directly or indirectly by the shareholders of the Company
in substantially the same proportions as their ownership of stock of the
Company; or (ii) during any period of two consecutive years, individuals who, at
the beginning of such period, constitute the Board of Directors of the Company
and any new director whose election by the Board of Directors or nomination for
election by the Company's shareholders was approved by a vote of at least two-
thirds of the directors then still in office, cease for any reason to constitute
a majority of the Board of Directors; or (iii) the shareholders of the Company
approve a merger or consolidation of the Company with any other corporation,
other than a merger or consolidation which would result in the Voting Securities
of the Company outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into Voting Securities of
the surviving entity) at least 80 percent of the total voting power represented
by the Voting Securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation; or (iv) the shareholders of the
Company approve a plan of complete liquidation of the Company or an agreement
for the sale or disposition by the Company (in one transaction or a series of
transactions) of all or substantially all the Company's assets.

               b.  Claim means (i) any threatened, pending or completed action,
                   -----
suit or proceeding, whether civil, criminal, administrative or investigative, or
(ii) any inquiry or investigation, whether instituted by the Company or any
other party, that any of the Indemnitees in good faith believes might lead to
the institution of any such action, suit or proceeding.

                   --------

of the Company as a director, officer, employee, trustee, agent or fiduciary of
another corporation, partnership, joint venture, employee benefit plan, trust or
other enterprise, or by reason of anything done or not done by any of the

               e.  Indemnitees means the officers and directors of the Company
                   -----------
as of the date of this Agreement and any future duly elected officers and

               f.  Independent Legal Counsel means an attorney or firm of
                   -------------------------
attorneys, selected in accordance with the provisions of Section 3, who shall
not have otherwise performed services within the last three years for the
Company or the Indemnitee seeking indemnification (other than services with
respect to matters concerning the rights of any of the Indemnitees under this
Agreement).

               g.  Reviewing Party means (i) Independent Legal Counsel or (ii)
                   ---------------
any appropriate person or body consisting of a member or members of the

indemnification.

               h.  Voting Securities means any securities of the Company
                   -----------------                                    
which entitle their holders to vote generally in the election of directors.

          2.   Basic Indemnification Arrangement.
               --------------------------------- 

               a.  Indemnification.  In the event Indemnitee was, is or
                   ---------------                                     
becomes a party to or witness or other participant in, or is threatened to be
made a party to or witness or other participant in, a Claim by reason of an
Indemnifiable Event, the Company shall indemnify Indemnitee, to the fullest
extent permitted by law and as soon as practicable (but in any event no later
than thirty days after written demand is presented to the Company), against any
and all Expenses, judgments, fines, penalties and amounts paid in settlement
(including all interest, assessments and other charges paid or payable in
connection with or in respect of such Expenses, judgments, fines, penalties or
amounts paid in settlement) of such Claim.  If requested by Indemnitee, the
Company shall advance (within two business days of such request) any and all
Expenses to Indemnitee (an "Expense Advance").

               b.  Exception; Determination That Indemnification or
                   --------------------------------------------- --
Advances Not Permitted.  Except as provided in Section 2(c), the obligations of
- ----------------------                                                         
the Company

 
under Section 2(a) shall be subject to the condition that a Reviewing Party
shall not have determined that Indemnitee would not be permitted to be
indemnified under applicable law.  Except as provided in Section 2(c), the
obligation of the Company under Section 2(a) to make an Expense Advance shall be
subject to the condition that, if, when and to the extent a Reviewing Party
determines that Indemnitee would not be permitted to be indemnified under
applicable law, the Indemnitee shall reimburse the Company for all such Expense
Advances theretofore paid.  For purposes of this Section 2(b), if the Reviewing
Party is Independent Legal Counsel, then any such determination shall be
rendered in the form of a written opinion.

               c.  Initiation of Action Concerning Right to Indemnification. In
                   --------------------------------------------------------
the event Indemnitee has commenced or thereafter commences legal proceedings in
a court of competent jurisdiction to secure a determination that Indemnitee
should be indemnified under applicable law, any determination made by a
Reviewing Party that Indemnitee would not be permitted to be indemnified under
applicable law shall not be binding and Indemnitee shall not be required to
reimburse the Company for any Expense Advance until a final judicial
determination is made with respect thereto. Indemnitee shall have the right to
commence litigation in any court in the State of Michigan having subject matter
jurisdiction and in which venue is proper in order to seek an initial
determination by the court as to whether Indemnitee is entitled to
indemnification and Expense Advances hereunder or in order to challenge an
unfavorable determination by a Reviewing Party, including the legal or factual
bases for such unfavorable determination. The Company hereby consents to service
of process and to appear in any such proceeding. Unless contested by the
Indemnitee as contemplated by this Section 2(c), any determination by a
Reviewing Party shall be conclusive and binding on the Company and Indemnitee.

               d.  Reviewing Party.  For purposes of this Section 2, the
                   ---------------                                      
Reviewing Party shall be selected by the Board of Directors in circumstances
where there has not been a Change in Control.  In circumstances where there has
been a Change in Control (other than a Change in Control which has been approved
by a majority of the Company's Board of Directors who were directors immediately
prior to such Change in Control), the Reviewing Party shall be the Independent
Legal Counsel referenced in Section 3.

          3.   Change in Control.  The Company agrees that if there is a Change
               -----------------                                               
in Control of the Company (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control), then with respect to all matters
thereafter arising concerning the rights of Indemnitee under this Agreement or
any other agreement or Company Bylaw now or hereafter in effect relating to
Claims for Indemnifiable Events, the Company shall seek legal advice only from
Independent Legal Counsel selected by Indemnitee and approved by the Company
(which approval shall not be unreasonably withheld).  Such Independent Legal
Counsel, among other things, shall render its

 
written opinion to the Company and Indemnitee as to whether and to what extent
the Indemnitee would be permitted to be indemnified under applicable law.  The
Company agrees to pay the reasonable fees of Independent Legal Counsel and to
fully indemnify such counsel against any and all expenses (including attorneys'
fees), claims, liabilities and damages arising out of or relating to this
Agreement or such counsel's engagement pursuant hereto.

          4.  Indemnification for Additional Expenses.  In connection with any
              ---------------------------------------                         
action brought by Indemnitee for (i) indemnification or advance payment of
Expenses under this Agreement or any other agreement or Company Bylaw now or
hereafter in effect relating to Claims for Indemnifiable Events and/or (ii)
recovery under any directors' and officers' liability insurance policy
maintained by the Company, regardless of whether Indemnitee ultimately is
determined to be entitled to such indemnification, advance payment of Expenses
or insurance recovery, as the case may be, the Company shall indemnify
Indemnitee against any and all expenses (including attorneys' fees) which are
incurred by Indemnitee and, if requested by Indemnitee, shall (within two
business days of such request) advance such expenses to Indemnitee.

          5.  Partial Indemnity; Expenses.  If Indemnitee is entitled under
              ---------------------------                                  
any provision of this Agreement to indemnification by the Company for some or a
portion of Expenses, judgments, fines, penalties or amounts paid in settlement
of a Claim but not, however, for all of the total amount thereof, the Company
shall nevertheless indemnify Indemnitee for the portion to which Indemnitee is
entitled.  Moreover, notwithstanding any other provision of this Agreement, to
the extent that Indemnitee has been successful on the merits or otherwise in
defense (including dismissal without prejudice) of any or all Claims relating in
whole or in part to an Indemnifiable Event, or in defense of any issue or matter
relating in whole or in part to an Indemnifiable Event, Indemnitee shall be
indemnified against all Expenses incurred in connection therewith.

          6.  Burden of Proof.  In connection with any determination by a
              ---------------                                            
Reviewing Party as to whether Indemnitee is entitled to be indemnified
hereunder, the burden of proof shall be on the Company to establish that
Indemnitee is not entitled to indemnification.

          7.  No Presumptions.  For purposes of this Agreement, the
              ---------------                                      
termination of any claim, action, suit or proceeding by judgment, order,
settlement (whether with or without court approval) or conviction, or upon a
plea of nolo contendere or its equivalent, shall not create a presumption that
Indemnitee did not meet any particular standard of conduct or did have any
particular belief or that a court has determined that indemnification is not
permitted by applicable law.  Neither the failure of a Reviewing Party to have
made a determination as to whether Indemnitee has met any particular standard of
conduct or had any particular belief, nor an actual determination by a Reviewing
Party that Indemnitee has not met such standard of conduct or did not have

 
such belief, prior to the commencement of legal proceedings by Indemnitee as
contemplated in Section 2(c), shall be a defense to Indemnitee's claim or create
a presumption that Indemnitee has not met any particular standard of conduct or
did not have any particular belief.

              --------------------                                         
shall be in addition to any other rights Indemnitees may have under the
Company's Restated Articles of Incorporation, Bylaws, the applicable corporate
law, or otherwise.  To the extent that a change in the applicable corporate law
(whether by statute or judicial decision) permits greater indemnification by
agreement than would be afforded currently under the Company's Restated Articles
of Incorporation, Bylaws and this Agreement, it is the intent of the parties
hereto that Indemnitees shall enjoy by this Agreement the greater benefits so
afforded by such change.

          9.  Liability Insurance.  To the extent the Company maintains an
              -------------------

available for any Company director or officer.

              ---------------------                                          
claim or cause of action shall be asserted by or in the right of the Company
against any of the Indemnitees, Indemnitees' spouses, heirs, executors or
personal or legal representatives after the expiration of two years from the
date of accrual of such claim or cause of action. Any claim or cause of action
of the Company shall be extinguished and deemed released unless asserted by the
timely filing of a legal action within such two-year period; provided, however,
that if any shorter period of limitations is otherwise applicable to any such
claim or cause of action, such shorter period shall govern.

         11.  Amendments, Etc.  Any amendment to this Agreement necessitated

of director and/or officer of the Company need only by executed by the Company
and such person as an Indemnitee; provided, however, that no other supplement,
modification or amendment of this Agreement shall be binding unless executed in
writing by all of the parties hereto.  No waiver of any of the provisions of
this Agreement shall be deemed or shall constitute a waiver of any other
provisions hereof (whether or not similar), nor shall such waiver constitute a
continuing waiver.

         12.  Subrogation.  In the event of payment under this Agreement, the
              -----------                                                    
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of any of the Indemnitees.  Indemnitees shall execute all papers

identical counterparts, each of which shall be deemed to be an original, and all
of which together shall be deemed to be one and the same instrument when each
party has signed one such counterpart.

         17.  Governing Law.  This Agreement shall be governed by and
              -------------

                            ANN ARBOR STROMAL, INC.

                            1989 STOCK OPTION PLAN

                            Adopted August 15, 1989


     1.     PURPOSE.

            (a)     The purpose of the Plan is to provide a means which selected
key employees and directors (if declared eligible under paragraph 4) of and 
consultants to Ann Arbor Stromal, Inc., a Michigan corporation (the "Company"), 
and its Affiliates, as defined in subparagraph 1(b), may be given an opportunity
to purchase stock of the Company.

            (b)     The word "Affiliate" as used in the Plan means any parent 
corporation or subsidiary corporation of the Company, as those terms are defined
in Sections 425(e) and (f), respectively, of the Internal Revenue Code of 1986, 
as amended from time to time (the "Code").

            (c)     The Company, by means of the Plan, seeks to retain the 
services of persons now employed by or serving as consultants or directors to 
the Company, to secure and retain the services of new employees/persons capable 
of filling such positions, and to provide incentives for such persons to exert 
maximum efforts for the success of the Company.

            (d)     The Company intends that the options issued under the Plan 
shall, in the discretion of the Board of Directors of the Company (the "Board") 
or any committee to which responsibility for administration of the Plan has been
delegated

                                      1.



 
pursuant to subparagraph 2(c), be either incentive stock options as that term is
used in Section 422A of the Code ("Incentive Stock Options"), or options which 
do not qualify as incentive stock options ("Supplemental Stock Options"). All 
options shall be separately designated Incentive Stock Options or Supplemental 
Stock Options at the time of grant, and in such form as issued pursuant to 
paragraph 5, and a separate certificate or certificates shall be issued for 
shares purchased on exercise of each type of option. An option designated as a 
Supplemental Stock Option shall not be treated as an incentive stock option.

     2.     ADMINISTRATION.
            --------------

            (a)     The Plan shall be administered by the Board unless and until
the Board delegates administration to a committee, as provided in subparagraph 
2(c). Whether or not the Board has delegated administration, the Board shall 
have the final power to determine all questions of policy and expediency that 
may arise in the administration of the Plan.

            (b)     The Board shall have the power, subject to, and within the 
limitations of, the express provisions of the Plan:

                    (1)     To determine from time to time which of the persons 
eligible under the Plan shall be granted options; when and how the option shall 
be granted; whether the option will be an Incentive Stock Option or a 
Supplemental Stock Option; the provisions of each option granted (which need not
be identical), including the time or times during the term of each option within
which all or portions of such option may be exercised; and the

                                      2.

 
number of shares for which an option shall be granted to each such person.

                    (2)     To construe and interpret the Plan and options 
granted under it, and to establish, amend and revoke rules and regulations for 
its administration. The Board, in the exercise of this power, may correct any 
defect, omission or inconsistency in the Plan or in any option agreement, in a 
manner and to the extent it shall deem necessary or expedient to make the Plan 
fully effective.

                    (3)     To amend the Plan as provided in paragraph 10.

                    (4)     Generally, to exercise such powers and to perform 
such acts as the Board deems necessary or expedient to promote the best 
interests of the Company.

            (c)     The Board may delegate administration of the Plan to a 
committee composed of not fewer than three (3) members (the "Committee"), all of
the members of which Committee shall be disinterested persons, if required and 
as defined by the provisions of subparagraph 2(d). If administration is 
delegated to a Committee, the Committee shall have, in connection with the 
administration of the Plan, the powers theretofore possessed by the Board, 
subject, however, to such resolutions, not inconsistent with the provisions of 
the Plan, as may be adopted from time to time by the Board. The Board may 
abolish the Committee at any time and revest in the Board the administration of 
the Plan. Additionally, prior to the date of the first 

                                      3.

 
registration of an equity security of the Company under Section 12 of the 
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and 
notwithstanding anything to the contrary contained herein, the Board may 
delegate administration of the Plan to any person or persons and the term 
"Committee" shall apply to any person or persons to whom such authority has been
delegated.

            (d)     The term "disinterested person," as used in this Plan, shall
mean an administrator of the Plan, whether a member of the Board or of any 
Committee to which responsibility for administration of the Plan has been 
delegated pursuant to subparagraph 2(c): (i) who is not at the time he or she 
exercises discretion in administering the Plan eligible and has not at any time 
within one year prior thereto been eligible for selection as a person to whom 
stock may be allocated or to whom stock options or stock appreciation rights may
be granted pursuant to the Plan or any other plan of the Company or any of its 
affiliates entitling the participants therein to acquire stock, stock options or
stock appreciation rights of the Company or any of its affiliates; or (ii) who 
is otherwise considered to be a "disinterested person" in accordance with the 
rules, regulations or interpretations of the Securities and Exchange Commission.
Any such person shall otherwise comply with the requirements of Rule 16b-3 
promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange
Act").

                                      4.

 
            (e)     Any requirement that an administrator of the Plan be a 
"disinterested person" shall not apply (i) prior to the date of the first 
registration of an equity security of the Company under Section 12 of the 
Exchange Act, or (ii) if the Board or the Committee expressly declares that such
requirement shall not apply.

     3.     SHARES SUBJECT TO THE PLAN.
            --------------------------

            (a)     Subject to the provisions of paragraph 9 relating to 
adjustments upon changes in stock, the stock that may be sold pursuant to 
options granted under the Plan shall not exceed in the aggregate one million 
three hundred sixty-three thousand six hundred thirty-six (1,363,636) shares of 
the Company's common stock. If any option granted under the Plan shall for any 
reason expire or otherwise terminate without having been exercised in full, the 
stock not purchased under such option shall again become available for the Plan.

            (b)     The stock subject to the Plan may be unissued shares or 
reacquired shares, bought on the market or otherwise.

            (c)     An Incentive Stock Option may be granted to an eligible 
person under the Plan only if the aggregate fair market value (determined at the
time the option is granted) of the stock with respect to which incentive stock 
options (as defined in the Code) granted after 1986 are exercisable for the 
first time by such optionee during any calendar year under all incentive stock 
option plans of the Company and its Affiliates does not exceed one hundred 
thousand dollars ($100,000). Should it be determined 

                                      5.

 
that an option granted under the Plan exceeds such maximum for any reason other 
than the failure of a good faith attempt to value the stock subject to the 
option, such option shall be considered a Supplemental Stock Option to the 
extent, but only to the extent, of such excess; provided, however, that should 
it be determined that an entire option or any portion thereof does not qualify 
for treatment as an incentive stock option by reason of exceeding such maximum, 
such option or the applicable portion shall be considered a Supplemental Stock 
Option.

     4.     ELIGIBILITY.
            -----------

            (a)     Incentive Stock Options may be granted only to employees 
(including officers) of the Company or its Affiliates. A director of the Company
shall not be eligible to receive Incentive Stock Options unless such director is
also an employee (including an officer) of the Company or any Affiliate. 
Supplemental Stock Options may be granted only to key employees (including 
officers) of, directors of or consultants to the Company or its Affiliates. A 
director of the Company shall not be eligible for a Supplemental Stock Option 
unless such director is also a key employee (including an officer) of or 
consultant to the Company or any Affiliate.

            (b)     A director shall in no event be eligible for the benefits of
the Plan unless and until such director is expressly declared eligible to 
participate in the Plan by action of the Board or the Committee, and only if, at
any time discretion is exercised by the Board in the selection of a director as 
a person 

                                      6.

 

 
to whom options may be granted, or in the determination of the number of shares 
which may be covered by options granted to a director: (i) a majority of the 
Board and a majority of the directors acting in such matter are disinterested 
persons, as defined in subparagraph 2(d); (ii) the Committee consists solely of 
"disinterested persons" as defined in subparagraph 2(d); or (iii) the Plan 
otherwise complies with the requirements of Rule 16b-3 promulgated under the 
Exchange Act, as from time to time in effect. The Board shall otherwise comply 
with the requirements of Rule 16b-3 promulgated under the Exchange Act, as from 
time to time in effect. This subparagraph 4(b) shall not apply prior to the date
of the first registration of an equity security of the Company under Section 12 
of the Exchange Act.

            (c)     No person shall be eligible for the grant of an option under
the Plan if, at the time of grant, such person owns (or is deemed to own 
pursuant to Section 425(d) of the Code) stock possessing more than ten percent 
(10%) of the total combined voting power of all classes of stock of the Company 
or of any of its Affiliates unless the exercise price of such option is at least
one hundred ten percent (110%) of the fair market value of such stock at the 
date of grant and the term of the option does not exceed five (5) years from the
date of grant.

     5.     OPTION PROVISIONS.
            -----------------

            Each option shall be in such form and shall contain such terms and 
conditions as the Board or the Committee shall deem appropriate. The provisions 
of separate options need not be 

                                      7.

 
identical, but each option shall include (through incorporation of provisions 
hereof by reference in the option or otherwise) the substance of each of the 
following provisions:

            (a)     The term of any option shall not be greater than twelve (12)
years from the date it was granted.

            (b)     The exercise price of each Incentive Stock Option shall be 
not less than one hundred percent (100%) of the fair market value of the stock 
subject to the option on the date the option is granted. The exercise price of 
each Supplemental Stock Option shall be not less than eighty-five percent (85%) 
of the fair market value of the stock subject to the option on the date the 
option is granted.

            (c)     The purchase price of stock acquired pursuant to an option 
shall be paid, to the extent permitted by applicable statutes and regulations, 
either (i) in cash at the time the option is exercised, or (ii) at the 
discretion of the Board or the Committee, either at the time of the grant or 
exercise of the option, (A) by delivery to the Company of other common stock of 
the Company, (B) according to a deferred payment or other arrangement (which may
include, without limiting the generality of the foregoing, the use of other 
common stock of the Company) with the person to whom the option is granted or to
whom the option is transferred pursuant to subparagraph 5(d), or (C) in any 
other form of legal consideration that may be acceptable to the Board or the 
Committee.

                                      8.

 
     In the case of any deferred payment arrangement, interest shall be payable 
at least annually and shall be charged at the minimum rate of interest necessary
to avoid the treatment as interest, under any applicable provisions of the Code,
of any amounts other than amounts stated to be interest under the deferred 
payment arrangement.

            (d)     An option shall not be transferable except by will or by the
laws of descent and distribution, and shall be exercisable during the lifetime 
of the person to whom the option is granted only by such person.

            (e)     The total number of shares of stock subject to an option 
may, but need not, be allotted in periodic installments (which may, but need 
not, be equal). From time to time during each of such installment periods, the 
option may become exercisable ("vest") with respect to some or all of the shares
allotted to that period, and may be exercised with respect to some or all of the
shares allotted to such period and/or any prior period as to which the option 
was not fully exercised. During the remainder of the term of the option (if its 
term extends beyond the end of the installment periods), the option may be 
exercised from time to time with respect to any shares then remaining subject to
the option. The provisions of this subparagraph 5(e) are subject to any option 
provisions governing the minimum number of shares as to which an option may be 
exercised.

                                      9.

 
            (f)     The Company may require any optionee, or any person to whom 
an option is transferred under subparagraph 5(d), as a condition of exercising 
any such option, (1) to give written assurances satisfactory to the Company as 
to the optionee's knowledge and experience in financial and business matters 
and/or to employ a purchaser representative reasonably satisfactory to the 
Company who is knowledgeable and experienced in financial and business matters, 
and that he or she is capable of evaluating, alone or together with the 
purchaser representative, the merits and risks of exercising the option; and 
(2) to give written assurances satisfactory to the Company stating that such 
person is acquiring the stock subject to the option for such person's own 
account and not with any present intention of selling or otherwise distributing 
the stock. These requirements, and any assurances given pursuant to such 
requirements, shall be inoperative if (i) the issuance of the shares upon the 
exercise of the option has been registered under a then currently effective 
registration statement under the Securities Act of 1933, as amended (the 
"Securities Act"), or (ii) as to any particular requirement, a determination is 
made by counsel for the Company that such requirement need not be met in the 
circumstances under the then applicable securities laws.

            (g)     An option shall terminate three (3) months after termination
of the optionee's employment or relationship as a consultant or director with 
the Company or an Affiliate, unless (i) such termination is due to such person's
permanent and total 

                                      10.

 
disability, within the meaning of Section 422A(c)(7) of the Code, in which case 
the option may, but need not, provide that it may be exercised at any time 
within one (1) year following such termination of employment or relationship as 
a consultant or director; or (ii) the optionee dies while in the employ of or 
while serving as a consultant or director to the Company or an Affiliate, or 
within not more than three (3) months after termination of such relationship, in
which case the option may, but need not, provide that it may be exercised at any
time within eighteen (18) months following the death of the optionee by the 
person or persons to whom the optionee's rights under such option pass by will 
or by the laws of descent and distribution; or (iii) the option by its terms 
specifies either (a) that it shall terminate sooner than three (3) months after 
termination of the optionee's employment or relationship as a consultant or 
director, or (b) that it may be exercised more than three (3) months after 
termination of the relationship with the Company or an Affiliate. This 
subparagraph 5(g) shall not be construed to extend the term of any option or to 
permit anyone to exercise the option after expiration of its term, nor shall it 
be construed to increase the number of shares as to which any option is 
exercisable from the amount exercisable on the date of termination of the 
optionee's employment or relationship as a consultant or director.

            (h)     The option may, but need not, include a provision whereby 
the optionee may elect at any time during the term of his 

                                      11.

 
or her employment or relationship as a consultant or director with the Company 
or any Affiliate to exercise the option as to any part or all of the shares 
subject to the option prior to the stated vesting date of the option or of any 
installment or installments specified in the option. Any shares so purchased 
from any unvested installment or option may be subject to a repurchase right in 
favor of the Company or to any other restriction the Board or the Committee 
determines to be appropriate.

            (i)     To the extent provided by the terms of an option, the 
optionee may satisfy any federal, state or local tax withholding obligation 
relating to the exercise of such option by any of the following means or by a 
combination of such means: (1) tendering a cash payment; (2) authorizing the 
Company to withhold from the shares of the common stock otherwise issuable to 
the participant as a result of the exercise of the stock option a number of 
shares having a fair market value less than or equal to the amount of the 
withholding tax obligation; or (3) delivering to the Company owned and 
unencumbered shares of the common stock having a fair market value less than or 
equal to the amount of the withholding tax obligation.

     6.     COVENANTS OF THE COMPANY.
            ------------------------

            (a)     During the terms of the options granted under the Plan, the 
Company shall keep available at all times the number of shares of stock required
to satisfy such options.

                                      12.

 
            (b)     The Company shall seek to obtain from each regulatory 
commission or agency having jurisdiction over the Plan such authority as may be 
required to issue and sell shares of stock upon exercise of the options granted 
under the Plan; provided, however, that this undertaking shall not require the 
Company to register under the Securities Act either the Plan, any option granted
under the Plan or any stock issued or issuable pursuant to any such option. If, 
after reasonable efforts, the Company is unable to obtain from any such 
regulatory commission or agency the authority which counsel for the Company 
deems necessary for the lawful issuance and sale of stock under the Plan, the 
Company shall be relieved from any liability for failure to issue and sell stock
upon exercise of such options unless and until such authority is obtained.

     7.     USE OF PROCEEDS FROM STOCK.
            --------------------------

            Proceeds from the sale of stock pursuant to options granted under 
the Plan shall constitute general funds of the Company.

     8.     MISCELLANEOUS.
            -------------

            (a)     The Board or the Committee shall have the power to 
accelerate the time during which an option may be exercised or the time during 
which an option or any part thereof will vest pursuant to subparagraph 5(e), 
notwithstanding the provisions in the option stating the time during which it 
may be exercised or the time during which it will vest.

                                      13.

 
            (b)     Neither an optionee nor any person to whom an option is 
transferred under subparagraph 5(d) shall be deemed to be the holder of, or to 
have any of the rights of a holder with respect to, any shares subject to such 
option unless and until such person has satisfied all requirements for exercise 
of the option pursuant to its terms.

            (c)     Throughout the term of any option granted pursuant to the 
Plan, the Company shall make available to the holder of such option, not later 
than one hundred twenty (120) days after the close of each of the Company's 
fiscal years during the option term, upon request, such financial and other 
information regarding the Company as comprises the annual report to the 
shareholders of the Company provided for in the bylaws of the Company.

            (d)     Nothing in the Plan or any instrument executed or option 
granted pursuant thereto shall confer upon any eligible employee or optionee any
right to continue in the employ of the Company or any Affiliate (or to continue 
acting as a consultant or director) or shall affect the right of the Company or 
any Affiliate to terminate the employment or consulting relationship or 
directorship of any eligible employee or optionee with or without cause. In the 
event that an optionee is permitted or otherwise entitled to take a leave of 
absence, the Company shall have the unilateral right to (i) determine whether 
such leave of absence will be treated as a termination of employment for 
purposes of paragraph 5(g) hereof and corresponding provisions of 

                                      14.

 
any outstanding options, and (ii) suspend or otherwise delay the time or times 
at which the shares subject to the option would otherwise vest.

     9.     ADJUSTMENTS UPON CHANGES IN STOCK.

            (a)   If any change is made in the stock subject to the Plan, or 
subject to any option granted under the Plan (through merger, consolidation, 
reorganization, recapitalization, stock dividend, dividend in property other 
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or otherwise), the Plan and outstanding 
options will be appropriately adjusted in the class(es) and maximum number of 
shares subject to the Plan and the class(es) and number of shares and price per
share of stock subject to outstanding options.

            (b)     In the event of: (1) a dissolution or liquidation of the 
Company; (2) a merger or consolidation in which the Company is not the surviving
corporation; or (3) a reverse merger in which the Company is the surviving 
corporation but the shares of the Company's common stock outstanding 
immediately preceding the merger are converted by virtue of the merger into 
other property, whether in the form of securities, cash or otherwise then to the
extent permitted by applicable law: (i) any surviving corporation shall assume 
any options outstanding under the Plan or shall substitute similar options for 
those outstanding under the Plan, or (ii) such options shall continue in full 
force and effect. In the event any surviving corporation 

                                      15.

 
refuses to assume or continue such options, or to substitute similar options for
those outstanding under the Plan, then, with respect to options held by persons 
then performing services as employees or as consultants or directors for the 
Company as the case may be, the time during which such options may be exercised 
shall be accelerated and the options terminated if not exercised prior to such 
event.

     10.    AMENDMENT OF THE PLAN.
            ---------------------

            (a)     The Board at any time, and from time to time, may amend the 
Plan. However, except as provided in paragraph 9 relating to adjustments upon 
changes in stock, no amendment shall be effective unless approved by the 
shareholders of the Company within twelve (12) months before or after the 
adoption of the amendment, where the amendment will:

                    (i)     Increase the number of shares reserved for options 
under the Plan;

                    (ii)    Modify the requirements as to eligibility for 
participation in the Plan (to the extent such modification requires shareholder 
approval in order for the Plan to satisfy the requirements of Section 422A(b) of
the Code); or

                    (iii)   Modify the Plan in any other way if such 
modification requires shareholder approval in order for the Plan to satisfy the 
requirements of Section 422A(b) of the Code or to comply with the requirements 
of Rule 16b-3 promulgated under the Exchange Act.

                                      16.

 
            (b)     It is expressly contemplated that the Board may amend the 
Plan in any respect the Board deems necessary or advisable to provide optionees 
with the maximum benefits provided or to be provided under the provisions of the
Code and the regulations promulgated thereunder relating to employee incentive 
stock options and/or to bring the Plan and/or incentive stock options granted 
under it into compliance therewith.

            (c)     Rights and obligations under any option granted before 
amendment of the Plan shall not be altered or impaired by any amendment of the 
Plan unless (i) the Company requests the consent of the person to whom the 
option was granted and (ii) such person consents in writing.

     11.    TERMINATION OR SUSPENSION OF THE PLAN.
            -------------------------------------

            (a)     The Board may suspend or terminate the Plan at any time. 
Unless sooner terminated, the Plan shall terminate ten (10) years from the date 
the Plan is adopted by the Board or approved by the shareholders of the Company,
whichever is earlier. No options may be granted under the Plan while the Plan is
suspended or after it is terminated.

            (b)     Rights and obligations under any option granted while the 
Plan is in effect shall not be altered or impaired by suspension or termination 
of the Plan, except with the consent of the person to whom the option was 
granted.

     12.    EFFECTIVE DATE OF PLAN.
            ----------------------

            The Plan shall become effective as determined by the Board, but no 
options granted under the Plan shall be exercised 

                                      17.

 
unless and until the Plan has been approved by the shareholders of the Company.

                                      18.

 
                       INCENTIVE STOCK OPTION AGREEMENT
   
                                            OPTIONEE:

          AASTROM Biosciences, Inc., formerly known as Ann Arbor Stromal, Inc., 
(the "Company"), pursuant to its 1989 Stock Option Plan (the "Plan"), hereby 
grants to you, the Optionee named above, an option to purchase shares of the 
common stock of the Company ("Common Stock").  This option is intended to 
qualify as an "incentive stock option" within the meaning of Section 422A of the
Internal Revenue Code of 1986, as amended from time to time (the "Code").  The 
date of grant of this option is ____________.

          The grant hereunder is in connection with and in furtherance of the 
Company's compensatory benefit plan for participation of the Company's employees
(including officers), directors or consultants and is intended to comply with 
the provisions of Rule 701 promulgated by the Securities and Exchange 
Commission under the Securities Act of 1933, as amended (the "Act").

          The details of your option are as follows:

          1.  The total number of shares of Common Stock subject to this option
              is ___________. Subject to the limitations contained herein, this
              option shall be exercisable with respect to each installment shown
              below on or after the date of vesting applicable to such
              installment, as follows:

              Number of Shares                  Date of Earliest Exercise
              ----------------                  -------------------------
               (Installment)                            (Vesting)






provided, however, you will be entitled to exercise this option with respect to
all of the shares of Common Stock subject to this

                                     -1-

     option is your employment by the Company is terminated upon or at any time
     within six (6) months after the date of a "change of control" of the
     Company (as defined below), unless such termination is for cause (as
     defined below). For purposes of this Agreement, a "change of control" shall
     be deemed to have occurred if in a single transaction or a series of
     related transactions occurring within a twelve month period: all or
     substantially all of the business or assets of the Company is sold,
     transferred or leased; the Company is merged into or consolidated with
     another entity and, as a result, the shareholders of the Company
     immediately prior to the merger own less than 51% of the voting capital
     stock of the successor corporation; there is a change of control of 51% or
     more of the outstanding capital stock of the Company on a fully diluted
     basis; or a new shareholder acquires the right to elect a majority of the
     board of directors. The date of such "change of control" for purposes of
     this Agreement shall be the date of the closing of the transaction which is
     deemed to constitute a change of control under the foregoing sentence, or
     if a series of related transactions is deemed to constitute a change of
     control, the date of the closing of the last transaction in the series. For
     purposes of this Agreement, "cause" shall include disclosure of any
     proprietary information of the Company or of any third party in violation
     of the Proprietary Information and Invention Agreement between you and the
     Company; any commission of a felony; willful misconduct; or any commission
     of any act or series of acts of dishonesty which are injurious to the best
     interests of the Company.

2.   a. The exercise price of this option is ________ per share, being not less
        than the fair market value of the Common Stock on the date of grant of
        this option.

     b. Payment of the exercise price per share is due in full in cash
        (including check) upon exercise of the option with respect to all or
        any part of each installment which has become exercisable by you.
        Notwithstanding the foregoing, this option may be exercised pursuant to
        a program developed under Regulation T as promulgated by the Federal
        Reserve Board which results in the receipt of cash (or

                                      -2-

 
Incentive Stock Option Agreement

             check) by the Company prior to the issuance of
             Common Stock.  

     3.  The minimum number of shares with respect to which this option may be
         exercised at any one time is one hundred (100) except (a) as to an
         installment subject to exercise, as set forth in paragraph 1, which
         amounts to fewer than one hundred (100) shares, in which case, as to
         the exercise of that installment, the number of shares in such
         installment shall be the minimum number of shares, and (b) with respect
         to the final exercise of this option this paragraph 3 shall not apply.

     4.  Notwithstanding anything to the contrary contained herein, this option
         may not be exercised unless the shares issuable upon exercise of this
         option are then registered under the Act or if such shares are not then
         so registered, the Company has determined that such exercise and
         issuance is exempt from the registration requirements of the Act.

     5.  The term of this option commences on the date hereof and, unless sooner
         terminated as set forth below or in the Plan, terminates ten (10) years
         from the date this option is granted. This option shall terminate prior
         to the expiration of its term as follows: this option shall terminate
         three (3) months after the termination of your employment with the
         Company or an affiliate of the Company (as defined in the Plan) for any
         reason or for no reason (including without limitation a termination in
         connection with a "change of control" of the Company, as defined in
         paragraph 1 hereof) unless:

         a.  such termination of your employment is due to your permanent and
             total disability (within the meaning of Section 422A(c)(7) of the
             Code), in which event the option shall terminate on the earlier of
             the termination date set forth above or one (1) year following such
             termination of employment; or

         b.  such termination of employment is due to your death, in which event
             the option shall terminate on the earlier of the termination date
             set forth above or eighteen (18) months after your death; or

         c.  during any part of such three (3) month period the option is not
             exercisable solely because of the condition set forth in paragraph
             4 above, in which

                                      -3-
 




 
Incentive Stock Option Agreement
Page 4

             event the option shall not terminate until the earlier of the
             termination date set forth above or until it shall have been
             exercisable for an aggregate period of three (3) months after
             termination of employment; or
 
         d.  exercise of the option within three (3) months after termination of
             your employment with the Company or with an affiliate would result
             in liability under section 16(b) of the Securities Exchange Act of
             1934, in which case the option will terminate on the earlier of (i)
             the termination date set forth above, (ii) the tenth (10th) day
             after the last date upon which exercise would result in such
             liability or (iii) six (6) months and ten (10) days after the
             termination of your employment with the Company or an affiliate.

             However, this option may be exercised following termination of
             employment only as to that number of shares as to which it was
             exercisable under the provisions of paragraph 1 of this option on
             the date of termination of employment.

     6.  a.  This option may be exercised, to the extent specified above, by
             delivering a notice of exercise (in a form designated by the
             Company) together with the exercise price to the Secretary of the
             Company, or to such other person as the Company may designate,
             during regular business hours, together with such additional
             documents as the Company may then require pursuant to subparagraph
             5(f) of the Plan.

         b.  By exercising this option you agree that:

             (i)  The Company may require you to enter an arrangement providing
                  for the payment by you to the Company of any tax withholding
                  obligation of the Company arising by reason of (1) the
                  exercise of this option; (2) the lapse of any substantial risk
                  of forfeiture to which the shares are subject at the time of
                  exercise; or (3) the disposition of shares acquired upon such
                  exercise;

            (ii)  you will notify the Company in writing within fifteen (15)
                  days after the date of any

                                     -4-

               disposition of any of the shares of the Common Stock issued upon
               exercise of this option that occurs within two (2) years after
               the date of grant of the option hereunder or within one (1) year
               after such shares of Common Stock are transferred upon exercise
               of this option; and

     (iii)     the Company (or a representative of the underwriters) may, in
               connection with the first underwritten registration of the
               offering of any securities of the Company under the Act, require
               that you do not sell or otherwise transfer or dispose of any
               shares of Common Stock or other securities of the Company during
               such period (not to exceed one hundred fifty (150) days)
               following the effective date (the "Effective Date") of the
               registration statement of the Company filed under the Act as may
               be requested by the Company or the representative of the
               underwriters; provided, however, that such restriction shall
               apply only if, on the Effective Date, you are an officer,
               director, or owner of more than one percent (1%) of the
               outstanding securities of the Company. For purposes of this
               restriction, you will be deemed to own securities which (i) are
               owned directly or indirectly by you, including securities held
               for your benefit by nominees, custodians, brokers or pledgees;
               (ii) may be acquired by you within sixty (60) days of the
               Effective Date; (iii) are owned directly or indirectly, by or for
               your brothers or sisters (whether by whole or half blood),
               spouse, ancestors and lineal descendants; or (iv) are owned,
               directly or indirectly, by or for a corporation, partnership,
               estate or trust of which you are a shareholder, partner or
               beneficiary but only to the extent of your proportionate interest
               therein as a shareholder, partner or beneficiary thereof. You
               further agree that the Company may impose stop-transfer
               instructions with respect to securities subject to the foregoing
               restrictions until the end of such period.

                                     -5-

     7.   This option is not transferable, except by will or by the laws of
          descent and distribution, and is exercisable during your life only by
          you.

     8.   This option is not an employment contract and nothing in this option
          shall be deemed to create in any way whatsoever any obligation on your
          part to continue in the employ of the Company, or of the Company to
          continue your employment with the Company.

     9.   Any notices provided for in this option or the Plan shall be given in
          writing and shall be deemed effectively given upon receipt or, in the
          case of notices delivered by the Company to you, five (5) days after
          deposit in the United States mail, postage prepaid, addressed to you
          at the address specified below or at such other address as you
          hereafter designate by written notice to the Company.

     10.  This option is subject to all the provisions of the Plan, a copy of
          which is attached hereto and its provisions are hereby made a part of
          this option, including without limitation the provisions of paragraph
          5 of the Plan relating to option provisions, and is further subject to
          all interpretations, amendments, rules and regulations which may from
          time to time be promulgated and adopted pursuant to the Plan. In the
          event of any conflict between the provisions of this option and those
          of the Plan, the provisions of the Plan shall control; provided,
          however, that you shall be entitled to receive stock options on
          additional shares of the Corporation's common stock to protect you
          against dilution of your share holding to the full extent provided by
          your Employment Agreement with the Company.

     Dated as of the ____ day of ___________, 19__.

                                                                    EXHIBIT 10.3

                          ANCILLARY STOCK OPTION PLAN

          THIS ANCILLARY STOCK OPTION PLAN (the "Ancillary Plan") is made as of
August 6, 1991, by Aastrom Biosciences, Inc. (the "Company"), with respect to
the facts set forth below.

                                    RECITALS

          A.   On August 15, 1989, the Company formally approved the 1989 Stock
Option Plan (the "1989 Plan"), pursuant to which the Board of Directors of the
Company (the "Board") is authorized to grant tax qualified "incentive stock
options" to employees of the Company or its affiliates and tax nonqualified
"supplemental stock options" to employees, officers, employed directors and
consultants of the Company or its affiliates.

          B.   In order to advance the growth and prosperity of the Company, the
Board believes that it is in the best interests of the Company to also grant
stock options on certain occasions to certain parties and persons selected by
the Board who are not otherwise eligible to receive stock options under the
terms of the 1989 Plan.

                                   AGREEMENT

          NOW, THEREFORE, Company hereby authorizes and establishes this
Ancillary Plan, pursuant to the terms and conditions set forth below.

          1.   Purpose.  The purpose of the Ancillary Plan is to advance the
growth and prosperity of the Company and its shareholders by providing
incentives to certain parties and persons selected by the Board who are not
otherwise eligible to receive stock options under the 1989 Plan.  The stock
options granted pursuant to this Ancillary Plan shall be treated as
"nonqualified tax options" under the U.S. Internal Revenue Code.

          2.   Term.     The term of this Ancillary Plan shall commence on the
date set forth above and shall terminate upon resolution by the Board.

          3.   Shares of Stock Subject to this Ancillary Plan.  The shares of
Common Stock which may be issued pursuant to the Ancillary Plan upon exercise of
stock options shall not exceed in the aggregate Fifty Thousand (50,000) shares
of the Company's Common Stock, unless otherwise approved by the Board by vote of
not less than two thirds (2/3) of the Board.  Such shares of Common Stock shall
be authorized and unissued shares.  The shares allocated to this Ancillary Plan
and the stock options granted pursuant to this Ancillary Plan are in addition
to, and not part of, the shares allocated to and granted pursuant to the 1989
Plan.

 
          4.   Administration of the Plan.  The Board shall administer the
Ancillary Plan, select the persons to whom stock options shall be granted,
determine the number of shares of Common Stock to be optioned and awarded,
determine the purchase price per share of Common Stock deliverable upon the
exercise of a stock option, determine the method of payment upon the exercise of
an option, and interpret, construe and implement the provisions of this
Ancillary Plan.  An option may be exercisable at any time from time to time,
subject to such timing, performance criteria, conditions and restrictions as
determined by the Board on a case by case basis for each option as set forth in
the Stock Option Agreements.

          5.   Stock Option Agreements.  The granting of stock options shall be
evidenced by a Stock Option Agreement, containing such terms and conditions as
the Board of Directors shall deem appropriate.  The provisions of the Stock
Option Agreements granted pursuant to this Ancillary Plan need not be identical,
may be similar to or different from the form of Stock Option Agreements granted
under the 1989 Plan, and may be customized as determined by the Board on a case
by case basis.

          6.   Amendment of this Ancillary Plan.  This Ancillary Plan may, at
any time or from time to time, be terminated, modified or amended by the Board.

          7.   Approval.  Approved by the Board on August 6, 1991.

                       ANCILLARY STOCK OPTION AGREEMENT

                                           Optionee:

     AASTROM Biosciences, Inc., formerly known as Ann Arbor Stromal, Inc., (the 
"Company"), pursuant to its Ancillary Stock Option Plan dated August 6, 1991 
(the "Plan"), has granted to you, the Optionee named above, an option to 
purchase shares of the common stock of the Company ("Common Stock").  This 
option is not intended to qualify and will not be treated as an "incentive stock
option" within the meaning of Section 422A of the Internal Revenue code of 1986,
as amended from time to time (the "Code").  The date of grant of this option is 
as of _________________, ____.

     The grant hereunder is a matter of separate inducement and agreement in 
connection with your services to the Company and not in lieu of any other 
compensation for services, and is intended to comply with the provisions of Rule
701 promulgated by the Securities and Exchange Commission under the Securities 
Act of 1933, as amended (the "Act"), and applicable state law exemptions from 
registration.

     The details of your option are as follows:

     1.   The total number of shares of Common Stock subject to this option is
          _____________________.  Subject to the limitations contained herein,
          including without limitation Section 5 hereof, this option shall be
          exercisable with respect to each installment shown below on or after
          the date of vesting applicable to such installment, as follows:

          Number of Shares                             Date of Earliest Exercise
          ----------------                             ------------------------
           (Installment)                                       (Vesting)

     2.   a.   The exercise price of this option is ___________ per share, being
               not less than the fair market value of the Common Stock on the
               date of grant of this option.

          b.   Payment of the exercise price per share is due in full in cash
               (including check) upon exercise of all or any part of each
               installment which has become exercisable by you.  Notwithstanding
               the foregoing, this option may be exercised pursuant to a program
               developed under Regulation T as promulgated by the Federal 
               Reserve Board which results in the receipt of cash (or check) by
               the Company prior to the issuance of Common Stock.

     3.   The minimum number of shares with respect to which this option may be
          exercised at any one time is one hundred (100) except (a) as to an
          installment subject to exercise, as set forth in paragraph 1, which
          amounts to fewer than one hundred (100) shares, in which case, as to
          the exercise of that installment, the number of shares in such
          installment shall be the minimum number of shares, and (b) with
          respect to the final exercise of this option this paragraph 3 shall
          not apply.

     4.   Notwithstanding anything to the contrary contained herein, this option
          may not be exercised unless the shares issuable upon exercise of this
          option are then registered under the Act or if such shares are not
          then so registered, the exercise and issuance of such shares would be
          exempt from the registration requirements of the Act.

     5.   The term of this option commences on the date hereof and, unless
          sooner terminated as set forth below, terminates twelve (12) years
          from the date this option is granted. This option shall terminate
          prior to the expiration of its term as follows: this option shall
          terminate three (3) months after the termination of your participation
          in the University of Michigan ex vivo bone marrow project more fully
          described in that certain Option Agreement dated March 24, 1989,
          between the Company, the University of Michigan and H&Q Life Science
          Technology Fund 1 (hereinafter such participation in the ex vivo bone
          marrow project

 
Ancillary Stock Option Agreement

               shall be referred to as "Employment") for any
               reason or for no reason unless:

               a.  such termination of your Employment is due to
                   your permanent and total disability (within
                   the meaning of Section 422A(c)(7) of the
                   Code), in which event the option shall
                   terminate on the earlier of the termination
                   date set forth above or one (1) year
                   following such termination of Employment; or

               b.  such termination of Employment is due to your
                   death, in which event the option shall
                   terminate on the earlier of the termination
                   date set forth above or eighteen (18) months
                   after your death; or

               c.  during any part of such three (3) month
                   period the option is not exercisable solely
                   because of the condition set forth in
                   paragraph 4 above, in which event the option
                   shall not terminate until the earlier of the
                   termination date set forth above or until it
                   shall have been exercisable for an aggregate
                   period of three (3) months after the
                   termination of Employment; or

               d.  exercise of the option within three (3)
                   months after termination of your Employment
                   would result in liability under section 16
                   (b) of the Securities Exchange Act of 1934,
                   in which case the option will terminate on
                   the earlier of (i) the tenth (10th) day after
                   the last date upon which exercise would
                   result in such liability or (ii) six (6)
                   months and ten (10) days after the
                   termination of your Employment; or

               e.  such termination of your Employment is a
                   temporary leave of absence occasioned by your
                   resuming studies at the University of
                   Michigan toward a doctorate degree, in which
                   event vesting of installments of this option
                   as set forth in Section 1 scheduled for any
                   date after the date on which the leave of
                   absence commenced (the "Leave Date") will be
                   suspended, and the vesting schedule set forth
                   in Section 1 shall be deemed to have been
                   amended as follows.  Should you Employment
       

 
Ancillary Stock Option Agreement
Page 4



             resume at any time during the two (2) year
             period after the Leave Date, vesting of
             installments of this option will resume, with
             the first suspended installment vesting on
             the date that your Employment resumes, the
             second suspended installment vesting 3 months
             thereafter, and so on, so that each
             succeeding suspended installment vests 3
             months after the date on which the previous
             suspended installment vested.  If your
             Employment does not resume during the two (2)
             year period after the Leave Date, this option
             will be deemed to have terminated on the
             Leave Date, and only those shares that vested
             on or prior to the Leave Date will be
             exercisable.

         f.  The termination of this option pursuant to
             this Section 5 shall apply only to those
             shares not yet vested according to the
             schedule contained in Section 1 herein, and
             any provision herein or in the Plan
             notwithstanding, shall not apply to such
             vested shares.  Any shares that have vested
             hereunder shall remain exercisable for the
             twelve (12) year period specified in this
             Section 5.

             However, this option may be exercised
             following termination of Employment only as
             to that number of shares as to which it was
             exercisable under the provisions of paragraph
             1 of this option on the date of termination
             of Employment.

     6.  a.  This option may be exercised, to the extent
             specified above, by delivering a notice to
             exercise (in a form designated by the
             Company) together with the exercise price to
             the Secretary of the Company, or to such
             other person as the Company may designate,
             during regular business hours, together with
             such additional documents as the Company may
             then require pursuant to subparagraph 5(f) of
             the Plan.

 
Ancillary Stock Option Agreement

         b.  By exercising this option you agree that:

             (i)   the Company may require you to enter an arrangement providing
                   for the cash payment by you to the Company of any tax
                   withholding obligation of the Company arising by reason of
                   (1) the exercise of this option; (2) the lapse of any
                   substantial risk of forfeiture to which the shares are
                   subject at the time of exercise; or (3) the disposition of
                   shares acquired upon such exercise;

             (ii)  the Company (or a representative of the underwriters) may, in
                   connection with the first underwritten registration of the
                   offering of any securities of the Company under the Act,
                   require that you not sell or otherwise transfer or dispose of
                   any shares of Common Stock or other securities of the Company
                   during such period (not to exceed one hundred fifty (150)
                   days) following the effective date (the "Effective Date") of
                   the registration statement of the Company filed under the Act
                   as may be requested by the Company or the representative of
                   the underwriters; provided, however, that such restriction
                   shall apply only if, on the Effective Date, you are an
                   officer, director, or owner of more than one percent (1%) of
                   the outstanding securities of the Company. For purposes of
                   this restriction, you will be deemed to own securities which
                   (i) are owned directly or indirectly by you, including
                   securities held for your benefit by nominees, custodians,
                   brokers or pledgees; (ii) may be acquired by you within sixty
                   (60) days of the Effective Date; (iii) are owned directly or
                   indirectly, by or for your brothers or sisters (whether by
                   whole or half blood), spouse, ancestors and lineal
                   descendants; or (iv) are owned, directly or indirectly, by or
                   for a corporation, partnership, estate or trust of which you
                   are a shareholder, partner or
                   





 
Ancillary Stock Option Agreement
Page 6



                  beneficiary, but only to the extent of your proportionate
                  interest therein as a shareholder, partner or beneficiary
                  thereof. You further agree that the Company may impose stop-
                  transfer instructions with respect to securities subject to
                  the foregoing restrictions until the end of such period.

     7.  This option is not transferable, except by will or by the laws of
         descent and distribution, and is exercisable during your life only by
         you.

     8.  Upon exercise of the option in whole or in part, you will be required
         to execute a Stock Transfer Restriction and Buy-Out Agreement
         substantially in the form attached hereto, which sets forth
         restrictions on transfer of the Stock and gives the Company the right
         to purchase the Stock under certain circumstances.

     9.  This option is not an employment contract and nothing in this option
         shall be deemed to create in any way whatsoever any obligation on your
         part to continue Employment, or of the Company to employ you.

     10. Any notices provided for in this option or the Plan shall be given in
         writing and shall be deemed effectively given upon receipt or, in the
         case of notices delivered by the Company to you, five (5) days after
         deposit in the United States mail, postage prepaid, addressed to you at
         the address specified below or at such other address as you hereafter
         designate by written notice to the Company.

     11. This option is subject to all the provisions of the Plan, a copy of
         which is attached hereto and its provisions are hereby made a part of
         this option, including without limitation the provisions of paragraph 5
         of the Plan relating to stock option agreements, and is further subject
         to all interpretations, amendments, rules and regulations which may
         from time to time be promulgated and adopted pursuant to the Plan. In
         the event of any conflict between the provisions of this option and
         those of the Plan, the provisions of the Plan shall control.

                           AASTROM BIOSCIENCES, INC.
                              AMENDED AND RESTATED
                               1992 INCENTIVE AND
                        NON-QUALIFIED STOCK OPTION PLAN
                    (AS AMENDED EFFECTIVE OCTOBER 30, 1996)


     Section 1.  Purpose.
 
     The purpose of the 1992 Incentive and Non-qualified Stock Option Plan (the
"Plan") of Aastrom Biosciences, Inc. (the "Company") is to encourage stock
ownership by directors, officers, employees of and consultants to the Company
and its Affiliates and others who directly or indirectly provide goods or
services to the Company and its Affiliates by issuing options to purchase shares
of the Company's stock ("Options," and individually an "Option"), enabling such
persons to acquire or increase their proprietary interest in the Company and
thereby encouraging them to remain in the employ or remain directors of or
consultants to the Company and its Affiliates or continue providing goods or
services to the Company and its Affiliates. The term "Affiliates" as used herein
shall include any parent corporation or subsidiary corporation as defined in
Sections 424(e) and (f) respectively of the Internal Revenue Code of 1986, as
amended (the "Code"). The Options issued pursuant to the Plan are intended to
constitute either incentive stock options within the meaning of Section 422 of
the Code, or non-qualified stock options, at the discretion of the Option
Committee (as hereinafter defined) of the board of directors of the Company (the
"Board of Directors") at the time of grant. The type of Options granted will be
specified in the letter of grant to the person who is granted the Options (the
"Optionee"). The terms of this Plan shall be incorporated in the grant letter.

     Section 2.  Administration.
 
     The Plan will be administered by the Board of Directors or a committee of
two or more members of the Board or Directors (such member or the Board of
Directors acting as Plan administrators shall be referred to herein as the
"Option Committee"). If the Company or an Affiliate is a "publicly held
corporation" within the meaning of Section 162(m) of the Code, the Board may
establish a Committee of "outside directors" within the meaning of Section
162(m) to approve the grant of any Option which might reasonably be anticipated
to result in the payment of employee remuneration that would otherwise exceed
the limit on employee remuneration deductible for income tax purposes pursuant
to Section 162(m).


 
     The interpretation and construction by the Option Committee of any
provision of the Plan will be final. Anything herein to the contrary
notwithstanding, no member of the Board of Directors or the Option Committee
will be liable for any action or determination made in good faith with respect
to the Plan or any Option granted under it.

     Section 3.  Eligibility.

     Directors, officers and employees of the Company and its Affiliates who are
expected to make significant contributions to the long term success of the
Company are eligible to receive incentive stock options under the Plan, as may
be determined from time to time by the Option Committee. Directors, officers and
employees of and consultants to the Company and its Affiliates, and others who
directly or indirectly provide goods or services to the Company and its
Affiliates, are eligible to receive non-qualified options under the Plan, as may
be determined from time to time by the Option Committee. A director, officer,
employee, consultant or other person who is granted an Option is an Optionee
(which term also includes the Optionee's legal representative under Section 5(g)
hereof). An Optionee may be granted more than one Option.

     For purposes of the foregoing paragraph, "employees" shall include
prospective employees to whom Options are granted in connection with written
offers of employment with the Company or one of its Affiliates, and
"consultants" shall include prospective consultants to whom Options are granted
in connection with written offers of engagement with the Company or one of its
Affiliates.

     Any person who is not an employee on the date of Option grant may only be
granted a non-qualified stock option. A director who is not an employee or
officer of or consultant to the Company or its Affiliates, or who does not
directly or indirectly provide goods or services to the Company or its
Affiliates, shall not be eligible to receive non-qualified stock options.

     Notwithstanding the foregoing, no director of the Company who is not also
an employee of the Company may be granted an Option at any time that any class
of equity security of the Company is registered pursuant to Section 12 of the
Securities Exchange Act of 1934, as amended (the "Exchange Act").

     Section 4.  Stock.

     The stock subject to an Option will be shares of the Company's authorized
but unissued or reacquired Common Stock, no par value (the "Shares").  Options
shall not be issued with respect to more than One Million 

                                      -2-

 
Nine Hundred Thousand (1,900,000) Shares, after giving effect to the two-for-
three reverse stock split approved by the Board of Directors on April 30, 1996,
and subject to further adjustment as provided in Section 5(i) hereof. If an
outstanding Option for any reason expires or is terminated or canceled or Shares
acquired, subject to repurchase, upon the exercise of an Option are repurchased
by the Company, the Shares allocable to the unexercised portion of such Option,
or such repurchased Shares, shall again be available for issuance under the
Plan.

     Section 5.  Terms and Conditions of Options.

     Each Option granted pursuant to the Plan will be authorized by the Option
Committee and will be evidenced by a notice (the "Option Notice") in such form
as the Option Committee may from time to time determine. Each Option Notice will
include the information required in subparagraphs (a), (b) and (c) of this
Section 5 and will be in conformity with and will incorporate by reference all
other terms and conditions of the Plan, including the following terms and
conditions:

          (a) Number of Shares.  The number of Shares subject to the Option will
be stated in the Option Notice.

          (b) Exercise Price.  In the case of incentive stock options, the price
per Share payable on the exercise of the Option will be stated in the Option
Notice and will be not less than 100% of the fair market value per share of the
outstanding shares of Common Stock of the Company on the date the Option is
granted, without regard to any restriction other than a restriction which will
never lapse. In the case of a non-qualified stock option, the price per Share
payable upon exercise of the Option shall be stated in the Option Notice and
will be not less than 85% of the fair market value per share of the outstanding
shares of Common Stock of the Company on the date the Option is granted, without
regard to any restriction other than a restriction which will never lapse.
Unless the Company's Common Stock is quoted on the National Association of
Securities Dealers Automated Quotation System ("NASDAQ") or listed on a
recognized securities exchange, the fair market value, for purposes of complying
with the foregoing sentence with respect to incentive stock options, shall be as
determined by the Option Committee in its sole discretion. If the Company's
Common Stock is either quoted on NASDAQ or listed on a recognized securities
exchange, the fair market value shall be the representative closing price of the
stock as obtained from NASDAQ or such recognized securities exchange on the date
of the grant of the Option, or if there is no such quotation on the date of the
grant of the Option on the preceding business day.

          (c) Form of Option.  The Option Notice will state whether the Option
granted is an incentive stock option or a non-qualified stock 

                                      -3-

 
option, and will constitute a binding determination as to the form of Option
granted. At the discretion of the Option Committee, the Option Notice may
require the Optionee to execute a Stock Transfer Restriction and Buy-Out
Agreement, or such other agreements as the Option Committee considers
appropriate.

          (d) Payment.  The price payable on the exercise of the Option in whole
or in part will be equal to the Option price multiplied by the number of Shares
as to which the Option is exercisable, and shall be paid in full upon exercise
of any Option, either (i) in cash, (ii) at the discretion of the Option
Committee either at the time the Option is granted or exercised, by delivering
to the Company Shares having a fair market value, as of the close of business on
the day preceding such delivery, equal to the aggregate exercise price of the
Shares being purchased on exercise of the Options, (iii) by a combination of
such cash and shares, or (iv) any other form of legal consideration that may be
acceptable to the Option Committee. In the case of any deferred payment
arrangement, interest shall be payable at least annually at the minimum
applicable federal rate under Section 1274(d) of the Code to avoid imputed
interest to the Company under the Code.

     Anything to the contrary herein notwithstanding, all payments required to
be made by the Company hereunder to an Optionee, his legal representative, his
heir or devisee, shall be subject to the withholding of such amounts as the
Company may determine that it is required to withhold pursuant to any applicable
federal, state or local law or regulation. To the extent provided in the terms
of the Option, and to the extent allowed under the Exchange Act, the Optionee
may satisfy any federal, state or local tax withholding obligation relating to
the exercise of such Option by one or more of the following: (1) tender of a
cash payment; (2) authorization of the Company to withhold Shares otherwise to
be issued pursuant to the Option of a value not in excess of the withholding tax
obligation; or (3) delivering to the Company unencumbered Shares owned by the
Optionee of a value not in excess of the withholding tax obligation.

          (e) Notwithstanding any other provision of this Plan:

               (i) No Option shall be granted under this Plan more than ten (10)
years after April 30, 1996. Notwithstanding the foregoing, if the maximum number
of Shares issuable pursuant to the Plan as provided in Section 4 has been
increased at any time (other than pursuant to Section 5(i)), all Options shall
be granted, if at all, no later than the last day preceding the tenth (10th)
anniversary of the earlier of (a) the date on which the latest such increase in
the maximum number of Shares issuable under the Plan was approved by the
stockholders of the Company or (b) the date such amendment was adopted by the
Board of Directors.

                                      -4-

 
               (ii)   No incentive stock option granted under this Plan shall be
exercisable later than ten (10) years from the date of grant.

               (iii)  No Option granted to any Optionee shall be treated as an
incentive stock option, to the extent such Option would cause the aggregate fair
market value (determined as of the date of grant of each such Option) of the
Shares with respect to which incentive stock options are exercisable by such
Optionee for the first time during any calendar year to exceed $100,000. For
purposes of determining whether an incentive stock option would cause the
aggregate fair market value of the Shares to exceed the $100,000 limitation,
such incentive stock options shall be taken into account in the order granted.
For purposes of this subsection, incentive stock options include all incentive
stock options under all plans of the Company (or one of its Affiliates) that are
incentive stock option plans within the meaning of Section 422 of the Code. If
the Code is amended to provide for a different limitation from that set forth in
this subsection, such different limitation shall be deemed incorporated herein
effective as of the date and with respect to such Options as required or
permitted by such amendment to the Code.

               (iv) Options granted pursuant to this Plan may be exercised in
any order elected by the Optionee whether or not the Optionee holds any
unexercised Options under this Plan or any other Plan of the Company.

               (v)   Notwithstanding any provision herein to the contrary, no
incentive stock option shall be granted under this Plan to any person who, at
the time of the grant of such Option, owns stock possessing more than 10% of the
total combined voting power of all classes of the stock of the Company or any
affiliate, unless the option price at the time the Option is granted is at least
110 percent (110%) of the fair market value of the stock, and subject to the
condition that the Option expires five years from the Option grant date.

               (vi)  No Option granted under this Plan may be transferred except
by will or by the laws of descent and distribution.

          (f)  Term and Exercise of Options.

               (i)  Subject to the provisions of Section 5(e)(i), (ii) and (v)
hereof, Options granted hereunder may be exercisable in whole or in part at such
time or times as the Option Committee shall designate when granting such
Options. However, no Option granted to a prospective employee or prospective
consultant may become exercisable prior to the date on which such person
commences service with the Company or one of its Affiliates.

                                      -5-

 
               (ii)  Unless sooner terminated as provided in this Plan, each
Option shall expire no later than ten years from the date of grant and shall be
void and unexercisable thereafter. An Option may be exercised only by the
Optionee and may not be exercised by any other person except as provided in
Section 5(g) hereof.

          (g) Termination of Options Granted to Employees and Directors.

               (i)  Except as provided herein and unless otherwise specified in
the Option Notice, Options shall terminate when the Optionee ceases to be
employed by the Company or ceases to be a director of the Company.

               (ii)  Unless otherwise specified in the Option Notice, upon the
death of an Optionee while in the employ of the Company or while a director of
the Company, Options held by such Optionee which are exercisable on the date of
his or her death shall be exercisable by his or her executor(s) or
administrator(s) for a period of eighteen (18) months following the date of such
Optionee's death.

               (iii)  Unless otherwise specified in the Option Notice, upon
termination of an Optionee's employment with the Company (or if the Optionee is
a director only, upon termination of the Optionee's term of office, or if the
Optionee is both an employee and a director, upon termination of both) for any
reason other than "Cause," as defined in Section 5(g)(v), or for retirement or
permanent disability as set forth in Section 5(g)(iv) with respect to non-
qualified stock options, Options exercisable by such Optionee on the date of
termination of employment shall be exercisable by the Optionee (or in the case
of the Optionee's death subsequent to termination of employment, by the
Optionee's executor(s) or administrator(s)) for a period of three (3) months
from the date of such Optionee's termination of employment.

               (iv)  Solely with respect to non-qualified stock options, unless
otherwise specified in the Option Notice, upon termination of an Optionee's
employment with the Company (or if the Optionee is a director only, upon
termination of the Optionee's term of office, or if the Optionee is an employee
and a director, upon termination of both) for reasons of retirement or permanent
disability, non-qualified stock options exercisable by the Optionee on the date
of termination of employment shall be exercisable by such Optionee (or in the
case of the Optionee's death subsequent to termination of employment, by the
Optionee's executor(s) or administrator(s)) for a period of one (1) year from
the date of such Optionee's termination of employment; provided, however, that
if such

                                      -6-

 
Optionee shall commence any employment during this one (1) year period with a
competitor of the Company (including, but not limited to, full or part-time
employment or independent consulting work), as determined solely in the judgment
of the Board of Directors, all Options held by such Optionee which have not yet
been exercised shall terminate immediately upon commencement thereof.
 
               (v)  Unless otherwise specified in the Option Notice, upon the
termination of an Optionee's employment (or if the Optionee is a director only,
upon termination of the Optionee's term of office, or if the Optionee is both an
employee and a director, upon termination of both) for "Cause," as defined in
this Section 5(g)(v), all Options held by such Optionee shall terminate
concurrently with receipt by the Optionee of oral or written notice that his or
her employment has been terminated. For the purposes of this Plan, termination
for "Cause" shall include termination by reason of being convicted of any felony
or committing willful and gross negligence or willful and gross misconduct in
carrying out duties properly assigned to such Optionee by the Company.

               (vi)  The Option Notice may provide that the Options issued
thereunder may be exercised for one year following the "disability" of the
Optionee as such term is defined in Section 22(c)(3) of the Code.

               (vii)  In the case of a leave of absence taken by an Optionee,
the Company shall have the unilateral right to (1) determine whether such leave
of absence shall be treated as a termination of employment, and (2) suspend or
otherwise delay the time or times at which the Shares subject to the Option
would otherwise vest.

               (viii)  Options granted to employees and directors of the Company
and its Affiliates may be terminated at any time by agreement between the
Company and the Optionee.

          (h)  Termination of Options Granted to Non-Employees.

               (i)  With respect to Options granted to persons who are not
employees or directors of the Company or its Affiliates, the Option Notice shall
state the conditions, if any, under which the Options shall terminate.

               (ii)  Options granted to persons who are not employees or
directors of the Company or its Affiliates may be terminated at any time by
agreement between the Company and the Optionee.

                                      -7-


 
          (i)  Recapitalization.

               (i)  Subject to any required action by the stockholders, if any,
the number of Shares as to which Options may be granted under this Plan and the
number of Shares subject to outstanding Options and the Option prices thereto
will be adjusted proportionately for any increase or decrease in the number of
outstanding shares of Common Stock of the Company resulting from stock splits
and reverse stock splits, but not for stock dividends. The number of Shares will
be adjusted to the nearest whole share. Any stock dividend resulting in an
increase of five percent (5%) or more in the outstanding Common Stock shall be
deemed a stock split.

               (ii)  If the Company is a party to any merger in which the
Company is not the surviving entity, any consolidation or dissolution (other
than the merger or consolidation of the Company with one or more of its wholly-
owned subsidiaries), the Company, in the discretion of the Option Committee and
to the extent permitted by law, (1) will cause any successor corporation to
assume the Options outstanding hereunder or substitute similar options to those
outstanding hereunder, or (2) will continue such Options in full force and
effect. In the event that any successor to the Company in a merger,
consolidation or dissolution will not assume the Options or substitute similar
Options then, with respect to Options held by Optionees then performing services
for the Company, the time for exercising such Options will be accelerated and
the Options will be terminated if not exercised prior to the merger,
consolidation or dissolution.

               (iii)  Except as expressly provided in this Section 5(i), the
Optionee will have no rights by reason of (1) any subdivision or consolidation
of shares of stock of any class of the Company; (2) payment of any stock
dividend by the Company; (3) any other increase or decrease in the number of
shares of stock of any class of the Company; or (4) by reason of any
dissolution, liquidation, merger, consolidation or spin-off of assets or stock
of another corporation.

               (iv)  The grant or existence of any Option shall not affect in
any way the right or power of the Company to make adjustments,
reclassifications, reorganizations, or changes of its capital or business
structure, or to merge, consolidate, dissolve, liquidate, sell or transfer all
or any part of its stock or assets.

          (j) Rights as a Stockholder.  The Optionee will have no rights as a
stockholder of the Company with respect to any Shares subject to an Option until
such Option has been exercised and a certificate with respect to the Shares
purchased upon exercise has been issued to him or

                                      -8-

 
her. No adjustment will be made for dividends (ordinary or extraordinary,
whether in cash, securities or other property), distributions or other rights
for which the record date is prior to the date the Shares so purchased have been
issued. Throughout the term of any Option issued hereunder, the Company shall
make available to each Optionee, not less than 120 days after the close of each
fiscal year of the Company, upon request by the Optionee, any financial or other
information contained in the annual report to the shareholders of the Company as
provided in the Company's by-laws.

          (k) Modification, Extension and Renewal of Option. Subject to the
terms and conditions of the Plan, the Option Committee may modify, extend or
renew an Option, or accept the surrender of an Option (to the extent not
theretofore exercised), provided that no incentive stock option may be modified,
extended or renewed if such action would cause it to cease to be an "incentive
stock option" under the Code. Notwithstanding the foregoing, no modification of
an Option which adversely affects the Optionee shall be made without the consent
of the Optionee.

          (l) Purchase for Investment.  The issuance of Shares on exercise of
the Option will be conditioned on obtaining appropriate representations and
warranties of the Optionee that the purchase of Shares thereunder will be for
investment, and not with a view to the public resale or distribution thereof,
unless the Shares subject to the Option are registered under the Securities Act
of 1933, as amended (the "Act"), and comply with any other law, regulation or
rule applicable thereto. Unless the Shares are registered under the Act, the
Optionee shall acknowledge that the Shares purchased on exercise of the Option
are not registered under the Act and may not be sold or otherwise transferred
unless the Shares have been registered under the Act in connection with the sale
or other transfer, or that counsel satisfactory to the Company is of the opinion
that the sale or other transfer is exempt from registration under the Act, and
unless said sale or transfer is in compliance with any other applicable law,
including all applicable state securities laws.

          (m) No Rights to Employment.  Officers or employees granted Options
under this Plan shall not have any right to continue in the employment of the
Company or its Affiliates by reason of the existence of such Options and
consultants granted Options under this Plan shall not have any right to continue
as consultants to the Company or its Affiliates by reason of the existence of
such options. Persons who directly or indirectly provide goods or services to
the Company or its Affiliates shall not have any right to continue providing
such goods and services by reason of the existence of such Options. An Optionee
who is not an employee of the Company or its Affiliates shall have no right to
become an employee, or to obtain any benefit of employment, by reason of having
been granted

                                      -9-

 
Options under this Plan. An Optionee whose employment is terminated shall have
no rights against the Company by reason of the termination of such Option
whether the termination of the employment be with or without "Cause," as defined
in Section 5(g)(iv).

          (n) Other Provisions.  The Option Notice may contain such other
provisions as the Option Committee in its discretion deems advisable and which
are not inconsistent with the provisions of this Plan, including, without
limitation, restrictions upon the exercise of the Option.

     Section 6.  Amendment of the Plan.

     Insofar as permitted by law and the Plan, the Option Committee may from
time to time suspend or discontinue the Plan or revise or amend it in any
respect whatsoever with respect to any Shares at the time not subject to an
Option; provided, however, that without approval of the stockholders, no such
revision or amendment may change the aggregate number of Shares for which
Options may be granted hereunder, change the designation of the class of
employees eligible to receive Options or decrease the price at which Options may
be granted.

     Any other provision of this Section 6 notwithstanding, the Option Committee
or the Board of Directors specifically is authorized to adopt any amendment to
this Plan deemed by the Board of Directors to be necessary or advisable to
assure that the incentive stock options or the non-qualified stock options
available under the Plan continue to be treated as such, respectively, under the
law.

     Section 7.  Application of Funds.

     The proceeds received by the Company from the sale of Shares pursuant to
the exercise of Options will be used for general corporate purposes.

     Section 8.  No Obligation to Exercise Option.

     The granting of an Option will impose no obligation upon the Optionee to
exercise such Option.

     Section 9.  Restrictions on Sale of Shares.  Optionee may not dispose of
any Shares received under the Plan within one hundred and eighty (180) days of
the date on which the Company's initial S-1 Registration Statement for
registration of the Company's common stock under the Securities Act of 1933, as
amended, is declared effective.

                                     -10-

 
     Section 10.  Indemnification.  In addition to such other rights of
indemnification as they may have as members of the Board of Directors or
officers or employees of the Company or one of its Affiliates, members of the
Board of Directors and any officers or employees of the Company or any one of
its Affiliates to whom authority to act for the Board of Directors is delegated
shall be indemnified by the Company against all reasonable expenses, including
attorneys' fees, actually and necessarily incurred in connection with the
defense of any action, suit or proceeding, or in connection with any appeal
therein, to which they or any of them may be a party by reason of any action
taken or failure to act under or in connection with the Plan, or any right
granted hereunder, and against all amounts paid by them in settlement thereof
(provided such settlement is approved by independent legal counsel selected by
the Company) or paid by them in satisfaction of a judgment in any such action,
suit or proceeding, except in relation to matters as to which it shall be
adjudged in such action, suit or proceeding that such person is liable for gross
negligence, bad faith or intentional misconduct in duties; provided, however,
that within sixty (60) days after the institution of such action, suit or
proceeding, such person shall offer to the Company, in writing, the opportunity
at its own expense to handle and defend the same.

     Section 11.  Approval of Stockholders.

     This Plan shall become effective on the date that it is adopted by the
Board of Directors; provided, however, that it shall become null and void if it
is not approved by a majority of the holders of the Company's Common Stock
within one year (365 days) of its adoption by the Board of Directors. The Option
Committee may grant Options hereunder prior to approval of the Plan or any
material amendments thereto by the holders of a majority of the Company's Common
Stock; provided, however, that no Option so granted shall be exercisable within
365 days of the date of the adoption or material amendment of the Plan, and all
Options so granted shall terminate and become null and void if the Plan is not
approved by a majority of the holders of the Company's Common Stock within 365
days of its adoption or material amendment.

                           AASTROM BIOSCIENCES, INC.
                            1992 EMPLOYEE INCENTIVE
                            STOCK OPTION AGREEMENT


     AASTROM BIOSCIENCES, INC., a Michigan corporation (the "Company"), hereby
grants to __________________ ("Optionee"), an option to purchase a total of
_________________ shares (the "Shares") of common stock of the Company, at the
price determined as provided herein, and in all respects subject to the terms,
definitions and provisions of the Company's 1992 Incentive and Non-Qualified
Stock Option Plan (the "Plan") incorporated herein by reference. Terms which are
defined in the Plan shall have the same meanings when used herein.

     1.   Nature of the Option. This Option is an incentive stock option within
the meaning of Section 422 of the Internal Revenue Code of 1986, as amended.

     2.   Exercise Price. The option price shall be __________________ for each
Share (the "Exercise Price"), which is not less than the fair market value of
each Share on the date hereof. The Option Price shall be adjusted
proportionately for increases or decreases in the number of outstanding Shares
resulting from stock splits.

     3.   Exercise of Option. Subject to Section 6 hereof, this Option shall be
exercisable during its term as follows:

          (a)  Right to Exercise. This Option shall be exercisable with respect
to ________________ Shares on ___________ and shall be exercisable with respect
to an additional _______________ Shares on the first day of every third month
thereafter, as long as Optionee remains an employee or director of the Company.

          (b)  Method of Exercise. This Option shall be exercisable by written
notice in the form of Exhibit A attached hereto. Such written notice shall be
signed by Optionee and shall be delivered in person, by certified mail, or by
such other means as the Company may permit to the Secretary of the Company. The
written notice shall be accompanied by payment of the aggregate Exercise Price.

     No Shares will be issued pursuant to the exercise of this Option unless
such issuance and such exercise shall comply with all relevant provisions of law
and the requirements of any stock exchange upon which the Shares may then be
listed.

 
          (c)  Number of Shares Exercisable. Each exercise of this Option in
part shall reduce, pro tanto, the total number of Shares that may thereafter be
purchased under such Option.

     4.   Optionee's Representations. If the shares which may be purchased
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended (the "Securities Act"), at the time this
Option is exercised, Optionee shall, concurrently with the exercise of all or
any portion of this Option, deliver to the Company his Investment Representation
Statement in the form attached hereto as Exhibit B.

     5.   Method of Payment. Payment of the Exercise Price, may be in any of the
following forms, or a combination thereof, in the discretion of the Company:

          (a)  cash or check in the full amount of the aggregate Exercise Price;
or

          (b)  surrender to the Company of other shares of Common Stock of the
Company having a fair market value on the date of surrender equal to the
aggregate Exercise Price of the Shares as to which this Option is being
exercised. If the Company's Common Stock is then quoted on the National
Association of Securities Dealers Automated Quotation System ("Nasdaq") or
listed on a recognized securities exchange, the fair market value of the shares
shall be the representative closing price of the stock as obtained from Nasdaq
or such recognized securities exchange on the date of the exercise of the
Option, or if there is no such quotation on the date of the exercise, on the
last trading day prior to the date of exercise. If the Company's Common Stock is
not quoted on Nasdaq or listed on a recognized securities exchange, the fair
market value of such shares shall be as determined by the Board of Directors in
its sole discretion; or

          (c)  promissory note, bearing a reasonable rate of interest, requiring
at least annual payments of accrued interest, maturing in not more than four (4)
years, secured by the shares purchased, and being a full recourse obligation of
the Optionee. Such recourse promissory note shall be in a form satisfactory to
the Company, and the Company may require the Optionee to deposit any shares
securing the promissory note with an agent designated by the Company under the
terms and conditions of escrow and security agreements approved by the Company.
It shall be at the sole and absolute discretion of the Company's Board of
Directors as to whether or not the Optionee is allowed to exercise this Option
by a

                                      -2-

 
promissory note payment, and the Optionee shall have no right to do so unless
the Board of Directors expressly exercises its discretion to allow the use of a
promissory note. Any such approval by the Board of Directors shall not
constitute a precedent for any subsequent exercise of this Option by the
Optionee.

          (d)  through "Cashless Exercise." A "Cashless Exercise" means the
assignment in a form acceptable to the Company of the proceeds of a sale or loan
with respect to some or all of the Shares of Common Stock acquired upon the
exercise of the Option pursuant to a program or procedure approved by the
Company (including, without limitation, through an exercise complying with the
provisions of Regulation T as promulgated from time to time by the Board of
Governors of the Federal Reserve System). The Company reserves, at any and all
times, the right, in the Company's sole and absolute discretion, to decline to
approve or terminate any such program or procedure.

     6.   Restrictions on Exercise. This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such Shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("Regulation G") as
promulgated by the Federal Reserve Board. As a condition to the exercise of this
Option, the Company may require the Optionee to make any representation and
warranty to the Company as may be required by any applicable law or regulation.

     7.   Termination of Options.

          (a)  Except as provided herein, this Option shall terminate at such
time as Optionee ceases to be employed by the Company or ceases to be a director
of the Company.

          (b)  Upon the death of Optionee while in the employ of the Company or
while a director of the Company, Options held by Optionee which are exercisable
on the date of his or her death shall be exercisable by his or her executor(s)
or administrator(s) for a period of eighteen (18) months following the date of
Optionee's death.

          (c)  Upon termination of Optionee's employment with the Company (or if
Optionee is a director only, upon termination of the Optionee's term of office,
or if the Optionee is both an employee and a director, upon termination of both)
for any reason other than death,

                                      -3-

 
disability or "Cause," as defined in Section 7(d), Options exercisable by
Optionee on the date of termination of employment shall be exercisable by
Optionee (or in the case of the Optionee's death subsequent to termination of
employment, by the Optionee's executor(s) or administrator(s)) for a period of
three (3) months from the date of Optionee's termination of employment.

          (d)  Upon the termination of Optionee's employment (or if Optionee is
a director only, upon termination of Optionee's term of office, or if Optionee
is both an employee and a director, upon termination of both) for "Cause," as
defined in this Section 7(d), all Options held by Optionee shall terminate
concurrently with receipt by the Optionee of oral or written notice that his or
her employment has been terminated. Termination for "Cause" shall include
termination by reason of being convicted of any felony or committing willful and
gross negligence or willful and gross misconduct in carrying out duties properly
assigned to Optionee by the Company.

          (e)  Upon termination of Optionee's employment due to the "disability"
of Optionee as such term is defined in Section 22(c)(3) of the Code an Option
exercisable by Optionee on the date of termination shall be exercisable by
Optionee (or Optionee's legal guardian or representative) for a period of one
(1) year from the date of Optionee's termination of employment.

          (f)  Notwithstanding the provisions of subsections (b), (c) and (e)
above, if a sale within the applicable time periods set forth in subsections
(b), (c) and (e) of this Section 7 of shares acquired upon the exercise of the
Option would subject the Optionee to suit under Section 16(b) of the Exchange
Act, the Option shall remain exercisable until the earliest to occur of (i) the
tenth (10th) day following the date on which a sale of such shares by the
Optionee would no longer be subject to such suit, (ii) the one hundred and
ninetieth (190th) day after the Optionee's termination of employment or service,
or (iii) the Option term date determined pursuant to Section 8. The Company
makes no representation as to the tax consequences of any such delayed exercise.
The Optionee should consult with the Optionee's own tax advisor as to the tax
consequences to the Optionee of any such delayed exercise.

     8.   Non-Transferability of Option. This Option may not be sold, pledged,
assigned, hypothecated, transferred or disposed of in any manner during the
lifetime of Optionee other than by will or the laws of descent and distribution,
and may be exercised during the lifetime of the Optionee

                                      -4-

 
only by him or her. The terms of this Option shall be binding upon the
executors, administrators, heirs and successors of the Optionee.

     9.   Term of Option. This Option may not be exercised more than ten (10)
years from the date of grant of this Option, and may be exercised during such
term only in accordance with the terms of the Plan and this Option.

     10.  Early Disposition of Stock. Optionee hereby agrees that if he disposes
of any Shares received under this Option within one (1) year after such Shares
were transferred to him, or within two (2) years of the grant of this Option, he
will notify the Company in writing within 30 days after the date of any such
disposition.

     11.  Acknowledgment. The Optionee acknowledges receipt of a copy of the
Plan, which is annexed hereto as Exhibit C. The Optionee represents that he has
read the terms and provisions of the Plan and accepts this Option subject to all
of the terms and provisions thereof. The Optionee hereby agrees to accept as
binding, conclusive and final all decisions or interpretations of the Committee
upon any questions arising under the Plan.

     12.  Entire Agreement. This Agreement, together with the exhibits attached
hereto, represents the entire agreement between the parties.

     13.  Governing Law. This Agreement shall be construed in accordance with
the laws of the State of Michigan.

     14.  Amendment. This Agreement may only be amended by a writing signed by
each of the parties hereto.

P.O. Box 376
Ann Arbor, MI  48106
Attn.: Corporate Secretary


Dear Madam or Sir:

          I hereby notify AASTROM Biosciences, Inc. of my intent to exercise
___________ Options granted to me pursuant to a Stock Option Agreement dated
_______________ at an exercise price of $______ per share. I have enclosed a
check for $________.

          I hereby agree that if I dispose of any Shares received upon exercise
of the Option within one (1) year after this date of exercise, or within two (2)
years after the Date of Grant of this Option, I will notify the Company in
writing within 30 days after the date of any such disposition.

                                   EXHIBIT B

                      INVESTMENT REPRESENTATION STATEMENT
 
 
PURCHASER:   [                          ]
 
COMPANY:     Aastrom Biosciences, Inc.
 
SECURITY:    COMMON STOCK
 
AMOUNT:      [             ]  SHARES
 
DATE:        [                          ]

In connection with the purchase of the above-listed Securities, I, the
Purchaser, represent to the Company, the following:

          (a) I am aware of the Company's business affairs and financial
condition, and have acquired all such information about the Company as I deem
necessary and appropriate to enable me to reach an informed and knowledgeable
decision to acquire the Securities. I am purchasing these Securities for my own
account for investment and not with a view to, or for the resale in connection
with, any "distribution" thereof for purposes for the Securities Act of 1933, as
amended ("Securities Act").

          (b) I understand that the Securities have not been registered under
the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of my
investment intent as expressed herein.

          (c) I further understand that the Securities may not be sold publicly
and must be held indefinitely unless they are subsequently registered under the
Securities Act or unless an exemption from registration is available. I am able,
without impairing my financial condition, to hold the Securities for an
indefinite period of time and to suffer a complete loss of my investment. I
understand that the Company is under no obligation to register the Securities.
In addition, I understand that the certificate evidencing the Securities will be
imprinted with a legend which prohibits the transfer of the Securities unless
they are registered or such registration is not required in the opinion of
counsel for the Company.

          (d) I am familiar with the provisions of Rule 144, promulgated under
the Securities Act, which, in substance, permits limited public resale of
"restricted securities" acquired, directly or indirectly, from the issuer
thereof (or from an affiliate of such issuer), in a non-public offering subject
to the satisfaction of certain conditions, including, among other things: (1)
the availability of certain public information about the Company; (2) the resale
occurring not less than two years after the party has purchased, and made full
payment for, within the meaning of Rule 144, the securities to be sold; and (3)
in the case of an affiliate, or of a non-affiliate who has held the securities
less than three years, the sale being made through a broker in an unsolicited
"broker's transaction" or in transactions directly with a market maker (as said
term is defined under the Securities Exchange Act of 1934) and the amount of
securities being sold during any three month period not exceeding the specified
limitations stated therein, if applicable.

          (e) I further understand that at the time I wish to sell the
Securities there may be no public market upon which to make such a sale, and
that, even if such a public market then exists, the Company may not be
satisfying the current public information requirements of Rule 144, and that, in
such event, I would be precluded from selling the Securities under Rule 144 even
if the two-year minimum holding period had been satisfied. I understand that the
Company is not currently required to file reports pursuant to the Securities
Exchange Act of 1934, as amended, and is under no obligation to make Rule 144
available.

          (f) I further understand that, in the event all of the applicable
requirements of Rule 144 are not satisfied, registration under the Securities
Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 is not exclusive, the
Staff of the Securities and Exchange Commission has expressed its opinion that
persons proposing to sell private placement securities other than in a
registered offering and otherwise than pursuant to Rule 144 will have a
substantial burden of proof in establishing that an exemption from registration
is available for such offers or sales, and that such persons and their
respective brokers who participate in such transactions do so at their own risk.


                                      Signature of Purchaser:


                                      _________________________

                           AASTROM BIOSCIENCES, INC.
                          1992 EMPLOYEE NON-QUALIFIED
                            STOCK OPTION AGREEMENT


     AASTROM BIOSCIENCES, INC., a Michigan corporation (the "Company"),
hereby grants to _______________________ ("Optionee"), an option to purchase a
total of ____________ shares (the "Shares") of common stock of the Company, at
the price determined as provided herein, and in all respects subject to the
terms, definitions and provisions of the Company's 1992 Incentive and Non-
Qualified Stock Option Plan (the "Plan") incorporated herein by reference.
Terms which are defined in the Plan shall have the same meanings when used
herein.

     1. Nature of the Option. This Option is a non-qualified stock option and is
not intended to qualify for any special tax benefits to the Optionee.

     2. Exercise Price. The option price shall be $_______________ for each
Share (the "Exercise Price"), which is not less than the fair market value of
each Share on the date hereof. The Option Price shall be adjusted
proportionately for increases or decreases in the number of outstanding Shares
resulting from stock splits.

     3. Exercise of Option. Subject to Section 6 hereof, this Option shall be
exercisable during its term as follows:

          (a) Right to Exercise. This Option shall be exercisable with respect
to ______________ Shares on ______________ and shall be exercisable with respect
to an additional __________________ Shares on the first day of every third month
thereafter, as long as Optionee remains an employee, director or consultant of
the Company.

          (b) Method of Exercise. This Option shall be exercisable by written
notice in the form of Exhibit A attached hereto. Such written notice shall be
signed by Optionee and shall be delivered in person, by certified mail, or by
such other means as the Company may permit to the Secretary of the Company. The
written notice shall be accompanied by payment of the aggregate Exercise Price.

     No Shares will be issued pursuant to the exercise of this Option unless
such issuance and such exercise shall comply with all relevant
 

 
provisions of law and the requirements of any stock exchange upon which the
Shares may then be listed.

          (c) Number of Shares Exercisable. Each exercise of this Option in part
shall reduce, pro tanto, the total number of Shares that may thereafter be
purchased under such Option.

     4. Optionee's Representations. If the Shares which may be purchased
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended (the "Securities Act"), at the time this
Option is exercised, Optionee shall, concurrently with the exercise of all or
any portion of this Option, deliver to the Company his Investment Representation
Statement in the form attached hereto as Exhibit B.

     5. Method of Payment. Payment of the Exercise Price, may be in any of the
following forms, or a combination thereof, in the discretion of the Company:

          (a) cash or check in the full amount of the aggregate Exercise Price;
or

          (b) surrender to the Company of other shares of Common Stock of the
Company having a fair market value on the date of surrender equal to the
aggregate Exercise Price of the Shares as to which this Option is being
exercised. If the Company's Common Stock is then quoted on the National
Association of Securities Dealers Automated Quotation System ("Nasdaq") or
listed on a recognized securities exchange, the fair market value of the shares
shall be the representative closing price of the stock as obtained from the
Nasdaq or such recognized securities exchange on the date of the exercise of the
Option, or if there is no such quotation on the date of the exercise, on the
last trading day prior to the date of exercise. If the Company's Common Stock is
not quoted on Nasdaq or listed on a recognized securities exchange, the fair
market value of such shares shall be as determined by the Board of Directors in
its sole discretion; or

          (c) promissory note, bearing a reasonable rate of interest, requiring
at least annual payments of accrued interest, maturing in not more than four (4)
years, secured by the shares purchased, and being a full recourse obligation of
the Optionee. Such recourse promissory note shall be in a form satisfactory to
the Company, and the Company may require the Optionee to deposit any shares
securing the promissory note


                                      -2-

 
with an agent designated by the Company under the terms and conditions of escrow
and security agreements approved by the Company. It shall be at the sole and
absolute discretion of the Company's Board of Directors as to whether or not the
Optionee is allowed to exercise this Option by a promissory note payment, and
the Optionee shall have no right to do so unless the Board of Directors
expressly exercises its discretion to allow the use of a promissory note. Any
such approval by the Board of Directors shall not constitute a precedent for any
subsequent exercise of this Option by the Optionee.

          (d) through "Cashless Exercise". A "Cashless Exercise" means the
assignment in a form acceptable to the Company of the proceeds of a sale or loan
with respect to some or all of the Shares of Common Stock acquired upon the
exercise of the Option pursuant to a program or procedure approved by the
Company (including, without limitation, through an exercise complying with the
provisions of Regulation T as promulgated from time to time by the Board of
Governors of the Federal Reserve System). The Company reserves, at any and all
times, the right, in the Company's sole and absolute discretion, to decline to
approve or terminate any such program or procedure.

     6. Restrictions on Exercise. This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such Shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("Regulation G") as
promulgated by the Federal Reserve Board. As a condition to the exercise of this
Option, the Company may require the Optionee to make any representation and
warranty to the Company as may be required by any applicable law or regulation.

     7. Termination of Options.

          (a) Except as provided herein, this Option shall terminate at such
time as Optionee ceases to be employed by the Company or ceases to be a director
of or consultant to the Company.

          (b) Upon the death of Optionee while in the employ of the Company or
while a director of or consultant to the Company, Options held by Optionee which
are exercisable on the date of his or her death shall be exercisable by his or
her executor(s) or administrator(s) for a period of eighteen (18) months
following the date of Optionee's death.

                                      -3-

 
          (c) Upon termination of Optionee's employment with or service as a
consultant to the Company (or if Optionee is a director only, upon termination
of the Optionee's term of office, or if the Optionee is both an employee and a
director, upon termination of both) for any reason other than death, disability
or "Cause," as defined in Section 7(d), Options exercisable by Optionee on the
date of termination of employment or service shall be exercisable by Optionee
(or in the case of the Optionee's death subsequent to termination of employment,
by the Optionee's executor(s) or administrator(s)) for a period of three (3)
months from the date of Optionee's termination of employment or service.

          (d) Upon the termination of Optionee's employment or service as a
consultant (or if Optionee is a director only, upon termination of Optionee's
term of office, or if Optionee is both an employee and a director, upon
termination of both) for "Cause," as defined in this Section 7(d), all Options
held by Optionee shall terminate concurrently with receipt by the Optionee of
oral or written notice that his or her employment or service has been
terminated. Termination for "Cause" shall include termination by reason of being
convicted of any felony or committing willful and gross negligence or willful
and gross misconduct in carrying out duties properly assigned to Optionee by the
Company.

          (e) Upon termination of Optionee's employment or service as a
consultant due to the "disability" of Optionee as such term is defined in
Section 22(c)(3) of the Code an Option exercisable by Optionee on the date of
termination shall be exercisable by Optionee (or Optionee's legal guardian or
representative) for a period of one (1) year from the date of Optionee's
termination of employment or service.

          (f) Notwithstanding the provisions of subsections (b), (c) and (e)
above, if a sale within the applicable time periods set forth in subsections
(b), (c) and (e) of this Section 7 of shares acquired upon the exercise of the
Option would subject the Optionee to suit under Section 16(b) of the Exchange
Act, the Option shall remain exercisable until the earliest to occur of (i) the
tenth (10th) day following the date on which a sale of such shares by the
Optionee would no longer be subject to such suit, (ii) the one hundred and
ninetieth (190th) day after the Optionee's termination of employment or service,
or (iii) the Option term date determined pursuant to Section 8. The Company
makes no representation as to the tax consequences of any such delayed exercise.
The Optionee should consult with the Optionee's own tax advisor as to the tax
consequences to the Optionee of any such delayed exercise.

                                      -4-

 
     8. Non-Transferability of Option. This Option may not be sold, pledged,
assigned, hypothecated, transferred or disposed of in any manner during the
lifetime of Optionee other than by will or the laws of descent and distribution,
and may be exercised during the lifetime of the Optionee only by him or her. The
terms of this Option shall be binding upon the executors, administrators, heirs
and successors of the Optionee.

     9. Term of Option. This Option may not be exercised more than ten (10)
years from the date of grant of this Option, and may be exercised during such
term only in accordance with the terms of the Plan and this Option.

     10. Early Disposition of Stock. Optionee hereby agrees that if he disposes
of any Shares received under this Option within one (1) year after such Shares
were transferred to him, he will notify the Company in writing within 30 days
after the date of any such disposition.

     11. Acknowledgment. The Optionee acknowledges receipt of a copy of the
Plan, which is annexed hereto as Exhibit C. The Optionee represents that he has
read the terms and provisions of the Plan and accepts this Option subject to all
of the terms and provisions thereof. The Optionee hereby agrees to accept as
binding, conclusive and final all decisions or interpretations of the Committee
upon any questions arising under the Plan.

     12. Entire Agreement. This Agreement, together with the exhibits attached
hereto, represents the entire agreement between the parties.

     13. Governing Law. This Agreement shall be construed in accordance with the
laws of the State of Michigan.

each of the parties hereto.

Attn.: Corporate Secretary


Dear Madam or Sir:

___________ Options granted to me pursuant to a Stock Option Agreement dated
_______________ at an exercise price of $______ per share. I have enclosed a
check for $________.

                                   EXHIBIT B

                      INVESTMENT REPRESENTATION STATEMENT
 
 
PURCHASER:   [                          ]
 
COMPANY:     Aastrom Biosciences, Inc.
 
SECURITY:    COMMON STOCK
 
AMOUNT:      [             ]  SHARES
 
DATE:        [                          ]

In connection with the purchase of the above-listed Securities, I, the
Purchaser, represent to the Company, the following:

          (a) I am aware of the Company's business affairs and financial
condition, and have acquired all such information about the Company as I deem
necessary and appropriate to enable me to reach an informed and knowledgeable
decision to acquire the Securities. I am purchasing these Securities for my own
account for investment and not with a view to, or for the resale in connection
with, any "distribution" thereof for purposes for the Securities Act of 1933, as
amended ("Securities Act").

          (b) I understand that the Securities have not been registered under
the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of my
investment intent as expressed herein.

          (c) I further understand that the Securities may not be sold publicly
and must be held indefinitely unless they are subsequently registered under the
Securities Act or unless an exemption from registration is available. I am able,
without impairing my financial condition, to hold the Securities for an
indefinite period of time and to suffer a complete loss of my investment. I
understand that the Company is under no obligation to register the Securities.
In addition, I understand that the certificate evidencing the Securities will be
imprinted with a legend which prohibits the transfer of the Securities unless
they are registered or such registration is not required in the opinion of
counsel for the Company.

          (d) I am familiar with the provisions of Rule 144, promulgated under
the Securities Act, which, in substance, permits limited public resale of
"restricted securities" acquired, directly or indirectly, from the issuer
thereof (or
 

 
from an affiliate of such issuer), in a non-public offering subject to the
satisfaction of certain conditions, including, among other things: (1) the
availability of certain public information about the Company; (2) the resale
occurring not less than two years after the party has purchased, and made full
payment for, within the meaning of Rule 144, the securities to be sold; and (3)
in the case of an affiliate, or of a non-affiliate who has held the securities
less than three years, the sale being made through a broker in an unsolicited
"broker's transaction" or in transactions directly with a market maker (as said
term is defined under the Securities Exchange Act of 1934) and the amount of
securities being sold during any three month period not exceeding the specified
limitations stated therein, if applicable.

          (e) I further understand that at the time I wish to sell the
Securities there may be no public market upon which to make such a sale, and
that, even if such a public market then exists, the Company may not be
satisfying the current public information requirements of Rule 144, and that, in
such event, I would be precluded from selling the Securities under Rule 144 even
if the two-year minimum holding period had been satisfied. I understand that the
Company is not currently required to file reports pursuant to the Securities
Exchange Act of 1934, as amended, and is under no obligation to make Rule 144
available.

          (f) I further understand that, in the event all of the applicable
requirements of Rule 144 are not satisfied, registration under the Securities
Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 is not exclusive, the
Staff of the Securities and Exchange Commission has expressed its opinion that
persons proposing to sell private placement securities other than in a
registered offering and otherwise than pursuant to Rule 144 will have a
substantial burden of proof in establishing that an exemption from registration
is available for such offers or sales, and that such persons and their
respective brokers who participate in such transactions do so at their own risk.


                                      Signature of Purchaser:


                                      _________________________

     4.   SHARES SUBJECT TO PLAN.
          ---------------------- 

          4.1  MAXIMUM NUMBER OF SHARES ISSUABLE.  Subject to adjustment as
provided in Section 4.2, the maximum aggregate number of shares of Stock that
may be issued under the Plan shall be one hundred fifty thousand (150,000) (on a
post-split basis following the two-for-three reverse stock split of the Stock 
approved by the Board on April 30, 1996) and shall consist of authorized but
unissued shares or reacquired shares of Stock or any combination thereof. If an
outstanding Option for any reason expires or is terminated or canceled or shares
of Stock acquired, subject to repurchase, upon the exercise of an Option are
repurchased by the Company, the shares of Stock allocable to the unexercised
portion of such Option, or such repurchased shares of Stock, shall again be
available for issuance under the Plan.

          4.2  ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event of
any stock dividend, stock split, reverse stock split, recapitalization,
combination, reclassification or similar change in the capital structure of the
Company, appropriate adjustments shall be made in the number and class of shares
subject to the Plan, to the "Initial Option" and "Annual Option" (as defined in
Section 6.1), and to any outstanding Options, and in the exercise price of any
outstanding Options. If a majority of the shares which are of the same class as
the shares that are subject to outstanding Options are exchanged for, converted
into, or otherwise become (whether or not pursuant to an "Ownership Change
Event" as defined in Section 8.1) shares of another corporation (the "NEW
SHARES"), the Board may unilaterally amend the outstanding Options to provide
that such Options are exercisable for New Shares. In the event of any such
amendment, the number of shares subject to, and the exercise price of, the
outstanding Options shall be adjusted in a fair and equitable manner as
determined by the Board, in its sole discretion. Notwithstanding the foregoing,
any fractional share resulting from an adjustment pursuant to this Section 4.2
shall be rounded down to the nearest whole number, and in no event may the
exercise price of any Option be decreased to an amount less than the par value,
if any, of the stock subject to the Option.

                                       4

 
     5.   Eligibility and Type of Options.
          ------------------------------- 

          5.1  PERSONS ELIGIBLE FOR OPTIONS.  An Option shall be granted only to
a person who, at the time of grant, is an Outside Director.

          5.2  OPTIONS AUTHORIZED.  Options shall be nonstatutory stock options;
that is, options which are not treated as incentive stock options within the
meaning of Section 422(b) of the Code.

     6.  Terms and Conditions of Options.  Options shall be evidenced by Option
         -------------------------------                                       
Agreements specifying the number of shares of Stock covered thereby, in such
form as the Board shall from time to time establish.  Option Agreements may
incorporate all or any of the terms of the Plan by reference and shall comply
with and be subject to the following terms and conditions:

          6.1   AUTOMATIC GRANT OF OPTIONS.  Subject to execution by an Outside
Director of the appropriate Option Agreement, Options shall be granted
automatically and without further action of the Board, as follows:

               (a)  INITIAL OPTION.  Each person who (i) is an Outside Director
on the Effective Date, or (ii) first becomes an Outside Director after the
Effective Date shall be granted an Option to purchase five thousand (5,000)
shares of Stock on the Effective Date or the date he or she first becomes an
Outside Director, respectively (an "Initial Option").

               (b)  ANNUAL OPTION.  Each Outside Director (including any
Director of the Company who previously did not qualify as an Outside Director
but who subsequently becomes an Outside Director) shall be granted, on the date
immediately following the date of each annual meeting of the stockholders of the
Company (an "Annual Meeting") following which such person remains an Outside
Director, an Option to purchase five thousand (5,000) shares of Stock (an
"Annual Option"). Notwithstanding the foregoing, an Outside Director who has not
served continuously as a Director of the Company for at least six (6) months as
of the date immediately following such Annual Meeting shall not receive an
Annual Option on such date.

               (c)  RIGHT TO DECLINE OPTION.  Notwithstanding the foregoing, any
person may elect not to receive an Option by delivering written notice of such
election to the Board no later than the day prior to the date such Option would
otherwise be granted.  A person so declining an Option shall receive no payment
or other consideration in lieu of such declined Option.  A person who has
declined an Option may revoke such election by delivering written notice of such
revocation to the Board no later than the day prior to the date such Option
would be granted pursuant to Section 6.1(a) or (b), as the case may be.

          6.2  DISCRETION TO VARY OPTION SIZE.  Notwithstanding any provision of
the Plan to the contrary, the Board may, in its sole discretion, increase or
decrease the number of shares of Stock that would otherwise be subject to one or
more Initial Options or Annual Options to be granted pursuant to Section 6.1 if,
at the time of such exercise of discretion, the exercise of such discretion
would not otherwise preclude any transaction in an equity security of the
Company by an officer or Director of a Participating Company from being exempt
from Section 16(b) of the Exchange Act pursuant to Rule 16b-3.

          6.3  EXERCISE PRICE.  The exercise price per share of Stock subject
to an Option shall be the Fair Market Value of a share of Stock on the date the
Option is granted.

          6.4  EXERCISE PERIOD.  Each Option shall terminate and cease to be
exercisable on the date ten (10) years after the date of grant of the Option
unless earlier terminated pursuant to the terms of the Plan or the Option
Agreement.

          6.5  RIGHT TO EXERCISE OPTIONS.

               Except as otherwise provided in the Plan or in the Option 
Agreement, an Option shall (a) first become exercisable on the date which is one
(1) month after the date on which the Option was granted (the "Initial Vesting
Date"); and (b) be exercisable on and after the Initial Vesting Date and prior
to the termination thereof in an amount equal to the number of shares of Stock
initially subject to the Option multiplied by the Vested Ratio as set forth
below, less the number of shares previously acquired upon exercise thereof. The
Vested Ratio described in the preceding sentence shall be determined as follows:

Vested Ratio ------------ Prior to Initial Option Vesting Date 0 On Initial Vesting Date, provided 1/12 the Optionee's Service is continuous from the date of grant of the Option until the Initial Vesting Date Plus ---- For each full month of 1/12 of the Optionee's continuous
6 Service from the Initial Vesting Date until the Vested Ratio equals 1/1, an additional 6.6 PAYMENT OF EXERCISE PRICE. (a) FORMS OF CONSIDERATION AUTHORIZED. Except as otherwise provided below, payment of the exercise price for the number of shares of Stock being purchased pursuant to any Option shall be made (i) in cash, by check, or cash equivalent, (ii) by tender to the Company of shares of Stock owned by the Optionee having a Fair Market Value not less than the exercise price, (iii) by the assignment of the proceeds of a sale or loan with respect to some or all of the shares being acquired upon the exercise of the Option (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System) (a "CASHLESS EXERCISE"), or (iv) by any combination thereof. 7 (b) TENDER OF STOCK. Notwithstanding the foregoing, an Option may not be exercised by tender to the Company of shares of Stock to the extent such tender of Stock would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company's stock. Unless otherwise provided by the Board, an Option may not be exercised by tender to the Company of shares of Stock unless such shares either have been owned by the Optionee for more than six (6) months or were not acquired, directly or indirectly, from the Company. (c) CASHLESS EXERCISE. The Company reserves, at any and all times, the right, in the Company's sole and absolute discretion, to establish, decline to approve or terminate any program or procedures for the exercise of Options by means of a Cashless Exercise. 6.7 TAX WITHHOLDING. The Company shall have the right, but not the obligation, to deduct from the shares of Stock issuable upon the exercise of an Option, or to accept from the Optionee the tender of, a number of whole shares of Stock having a Fair Market Value equal to all or any part of the federal, state, local and foreign taxes, if any, required by law to be withheld by the Participating Company Group with respect to such Option or the shares acquired upon exercise thereof. Alternatively or in addition, in its sole discretion, the Company shall have the right to require the Optionee to make adequate provision for any such tax withholding obligations of the Participating Company Group arising in connection with the Option or the shares acquired upon exercise thereof. The Company shall have no obligation to deliver shares of Stock until the Participating Company Group's tax withholding obligations have been satisfied. 7. STANDARD FORM OF OPTION AGREEMENT. --------------------------------- 7.1 INITIAL OPTION. Unless otherwise provided for by the Board at the time an Initial Option is granted, each Initial Option shall comply with and be subject to the terms and conditions set forth in the form of Nonstatutory Stock Option Agreement for Outside Directors (Initial Option) adopted by the Board concurrently with its adoption of the Plan and as amended from time to time. 7.2 ANNUAL OPTION. Unless otherwise provided for by the Board at the time an Annual Option is granted, each Annual Option shall comply with and be subject to the terms and conditions set forth in the form of Nonstatutory Stock Option Agreement for Outside Directors (Annual Option) adopted by the Board concurrently with its adoption of the Plan and as amended from time to time. 7.3 AUTHORITY TO VARY TERMS. Subject to the limitations set forth in Section 3.2, the Board shall have the authority from time to time to vary the terms of any of the standard forms of Option Agreement described in this Section 7 either in connection with the grant or amendment of an individual Option or in connection with the authorization of a new standard form or forms; provided, 8 however, that the terms and conditions of any such new, revised or amended standard form or forms of Option Agreement are not inconsistent with the terms of the Plan. Such authority shall include, but not by way of limitation, the authority to grant Options which are immediately exercisable subject to the Company's right to repurchase any unvested shares of Stock acquired by the Optionee upon the exercise of an Option in the event such Optionee's Service is terminated for any reason. 8. TRANSFER OF CONTROL. ------------------- 8.1 DEFINITIONS. (a) AN "OWNERSHIP CHANGE EVENT" shall be deemed to have occurred if any of the following occurs with respect to the Company: (i) the direct or indirect sale or exchange in a single or series of related transactions by the stockholders of the Company of more than fifty percent (50%) of the voting stock of the Company; (ii) a merger or consolidation in which the Company is a party; (iii) the sale, exchange, or transfer of all or substantially all of the assets of the Company; or (iv) a liquidation or dissolution of the Company. (b) A "TRANSFER OF CONTROL" shall mean an Ownership Change Event or a series of related Ownership Change Events (collectively, the "TRANSACTION") wherein the stockholders of the Company immediately before the Transaction do not retain immediately after the Transaction, in substantially the same proportions as their ownership of shares of the Company's voting stock immediately before the Transaction, direct or indirect beneficial ownership of more than fifty percent (50%) of the total combined voting power of the outstanding voting stock of the Company or the corporation or corporations to which the assets of the Company were transferred (the "TRANSFEREE CORPORATION(S)"), as the case may be. For purposes of the preceding sentence, indirect beneficial ownership shall include, without limitation, an interest resulting from ownership of the voting stock of one or more corporations which, as a result of the Transaction, own the Company or the Transferee Corporation(s), as the case may be, either directly or through one or more subsidiary corporations. The Board shall have the right to determine whether multiple sales or exchanges of the voting stock of the Company 9 or multiple Ownership Change Events are related, and its determination shall be final, binding and conclusive. 8.2 EFFECT OF TRANSFER OF CONTROL ON OPTIONS. In the event of a Transfer of Control, any unexercisable or unvested portion of the outstanding Options shall be immediately exercisable and vested in full as of the date ten (10) days prior to the date of the Transfer of Control. The exercise or vesting of any Option that was permissible solely by reason of this Section 8.2 shall be conditioned upon the consummation of the Transfer of Control. In addition, the surviving, continuing, successor, or purchasing corporation or parent corporation thereof, as the case may be (the "ACQUIRING CORPORATION"), may either assume the Company's rights and obligations under outstanding Options or substitute for outstanding Options substantially equivalent options for the Acquiring Corporation's stock. Any Options which are neither assumed or substituted for by the Acquiring Corporation in connection with the Transfer of Control nor exercised as of the date of the Transfer of Control shall terminate and cease to be outstanding effective as of the date of the Transfer of Control. Notwithstanding the foregoing, shares acquired upon exercise of an Option prior to the Transfer of Control and any consideration received pursuant to the Transfer of Control with respect to such shares shall continue to be subject to all applicable provisions of the Option Agreement evidencing such Option except as otherwise provided in such Option Agreement. Furthermore, notwithstanding the foregoing, if the corporation the stock of which is subject to the outstanding Options immediately prior to an Ownership Change Event described in Section 8.1(a)(i) constituting a Transfer of Control is the surviving or continuing corporation and immediately after such Ownership Change Event less than fifty percent (50%) of the total combined voting power of its voting stock is held by another corporation or by other corporations that are members of an affiliated group within the meaning of Section 1504(a) of the Code without regard to the provisions of Section 1504(b) of the Code, the outstanding Options shall not terminate. 9. NONTRANSFERABILITY OF OPTIONS. During the lifetime of the Optionee, ----------------------------- an Option shall be exercisable only by the Optionee or the Optionee's guardian or legal representative. No Option shall be assignable or transferable by the Optionee, except by will or by the laws of descent and distribution. 10. INDEMNIFICATION. In addition to such other rights of indemnification --------------- as they may have as members of the Board or officers or employees of the Participating Company Group, members of the Board and any officers or employees of the Participating Company Group to whom authority to act for the Board is delegated shall be indemnified by the Company against all reasonable expenses, including attorneys' fees, actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any right granted hereunder, and against all amounts paid by them in settlement thereof (provided such 10 settlement is approved by independent legal counsel selected by the Company) or paid by them in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct in duties; provided, however, that within sixty (60) days after the institution of such action, suit or proceeding, such person shall offer to the Company, in writing, the opportunity at its own expense to handle and defend the same. 11. TERMINATION OR AMENDMENT OF PLAN. The Board may terminate or amend -------------------------------- the Plan at any time. However, subject to changes in the law or other legal requirements that would permit otherwise, without the approval of the Company's stockholders, there shall be (a) no increase in the total number of shares of Stock that may be issued under the Plan (except by operation of the provisions of Section 4.2), and (b) no other amendment of the Plan that would require approval of the Company's stockholders under any applicable law, regulation or rule. In any event, no termination or amendment of the Plan may adversely affect any then outstanding Option, or any unexercised portion thereof, without the consent of the Optionee, unless such termination or amendment is necessary to comply with any applicable law or government regulation.

The Optionee's Service shall be deemed to have terminated on account of death if the Optionee dies within three (3) months after the Optionee's termination of Service. 18 (c) OTHER TERMINATION OF SERVICE. If the Optionee's Service with the Participating Company Group terminates for any reason, except Disability or death, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee's Service terminated, may be exercised by the Optionee within three (3) months after the date on which the Optionee's Service terminated, but in any event no later than the Option Expiration Date. 7.2 EXTENSION IF EXERCISE PREVENTED BY LAW.

Notwithstanding the foregoing, if a sale, within the applicable time periods set forth in Section 7.1, of shares acquired upon the exercise of the Option would subject the Optionee to suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of such shares by the Optionee would no longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day after the Optionee's termination of Service, or (iii) the Option Expiration Date. 8. OWNERSHIP CHANGE AND TRANSFER OF CONTROL. ---------------------------------------- 8.1 DEFINITIONS. (a) An "OWNERSHIP CHANGE EVENT" shall be deemed to have occurred if any of the followin g occurs with respect to the Company: (i) the direct or indirect sale or exchange in a single or series of related transactions by the stockholders of the Company of more than fifty percent (50%) of the voting stock of the Company; (ii) a merger or consolidation in which the Company is a party; (iii) the sale, exchange, or transfer of all or substantially all of the assets of the Company; or (iv) a liquidation or dissolution of the Company. (b) A "TRANSFER OF CONTROL" shall mean an Ownership Change Event or a series of related Ownership Change Events (collectively, the "Transaction") wherein the stockholders of the Company immediately before the Transaction do not retain imme diately after the Transaction, in substantially the 19 same proportions as their ownership of shares of the Company's voting stock immediately before the Transaction, direct or indirect beneficial ownership of more than fifty percent (50%) of the total combined voting power of the outstanding voting stock of the Company or the corporation or corporations to which the assets of the Company were transferred (the "Transferee Corporation(s)"), as the case may be. For purposes of the preceding sentence, indirect beneficial ownership shall include, without limitation, an interest resulting from ownership of the voting stock of one or more corporations which, as a result of the Transaction, own the Company or the Transferee Corporation(s), as the case may be, either directly or through one or more subsidiary corporations. The Board shall have the right to determine whether multiple sales or exchanges of the voting stock of the Company or multiple Ownership Change Events are related, and its determination shall be final, binding and conclusive. 8.2 EFFECT OF TRANSFER OF CONTROL ON OPTION. In the event of a Transfer of Control, any unexercised portion of the Option shall be immediately exercisable and vested in full as of the date ten (10) days prior to the date of the Transfer of Control. Any exercise of the Option that was permissible solely by reason of this Section 8.2 shall be conditioned upon the consummation of the Transfer of Control. In addition, the surviving, continuing, successor, or purchasing corporation or parent corporation thereof, as the case may be (the "ACQUIRING CORPORATION"), may either assume the Company's rights and obligations under the Option or substitute for the Option a substantially equivalent option for the Acquiring Corporation's stock.

Notwithstanding the foregoing, shares acquired upon exercise of the Option prior to the Transfer of Control and any consideration received pursuant to the Transfer of Control with respect to such shares shall continue to be subject to all applicable provisions of this Option Agreement except as otherwise provided herein. Furthermore, notwithstanding the foregoing, if the corporation the stock of which is subject to the Option immediately prior to an Ownership Change Event described in Section 8.1(a)(i) constituting a Transfer of Control is the surviving or continuing corporation and immediately after such Ownership Change Event less than fifty percent (50%) of the total combined voting power of its voting stock is held by another corporation or by other corporations that are members of an affiliated group within the meaning of Section 1504(a) of the Code without regard to the provisions of Section 1504(b) of the Code, the Option shall not terminate. 9. ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event of any -------------------------------------------- stock dividend, stock split, reverse stock split, recapitalization, combination, reclassification, or similar change in the capital structure of the Company, appropriate adjustments shall be made in the number, Exercise Price and class of shares of stock subject to the Option. If a majority of the shares which are of the same class as the shares that are subject to the Option are exchanged for, 20 converted into, or otherwise become (whether or not pursuant to an Ownership Change Event) shares of another corporation (the "NEW SHARES"), the Board may unilaterally amend the Option to provide that the Option is exercisable for New Shares. In the event of any such amendment, the Number of Option Shares and the Exercise Price shall be adjusted in a fair and equitable manner, as determined by the Board, in its sole discretion. Notwithstanding the foregoing, any fractional share resulting from an adjustment pursuant to this Section 9 shall be rounded down to the nearest whole number, and in no event may the Exercise Price be decreased to an amount less than the par value, if any, of the stock subject to the Option. 10. RIGHTS AS A STOCKHOLDER. The Optionee shall have no rights as a ------------------------ stockholder with respect to any shares covered by the Option until the date of the issuance of a certificate for the shares for which the Option has been exercised (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such certificate is issued, except as provided in Section 9. 11. LEGENDS. The Company may at any time place legends referencing any ------- applicable federal, state or foreign securities law restrictions on all certificates representing shares of stock subject to the provisions of this Option Agreement. The Optionee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Optionee in order to carry out the provisions of this Section. 12. BINDING EFFECT. Subject to the restrictions on transfer set forth -------------- herein, this Option Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs, executors, administrators, successors and assigns. 13. TERMINATION OR AMENDMENT. The Board may terminate or amend the Plan ------------------------ or the Option at any time; provided, however, that no such termination or amendment may adversely affect the Option or any unexercised portion hereof without the consent of the Optionee unless such termination or amendment is necessary to comply with any applicable law, regulation or rule.

The Optionee's Service shall be deemed to have terminated on account of death if the Optionee dies within three (3) months after the Optionee's termination of Service. 29 (c) OTHER TERMINATION OF SERVICE. If the Optionee's Service with the Participating Company Group terminates for any reason, except Disability or death, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee's Service terminated, may be exercised by the Optionee within three (3) months after the date on which the Optionee's Service terminated, but in any event no later than the Option Expiration Date. 7.2 EXTENSION IF EXERCISE PREVENTED BY LAW.

Notwithstanding the foregoing, if a sale, within the applicable time periods set forth in Section 7.1, of shares acquired upon the exercise of the Option would subject the Optionee to suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of such shares by the Optionee would no longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day after the Optionee's termination of Service, or (iii) the Option Expiration Date. 8. OWNERSHIP CHANGE AND TRANSFER OF CONTROL. ---------------------------------------- 8.1 DEFINITIONS. (a) An "OWNERSHIP CHANGE EVENT" shall be deemed to have occurred if any of the following occurs with respect to the Company: (i) the direct or indirect sale or exchange in a single or series of related transactions by the stockholders of the Company of more than fifty percent (50%) of the voting stock of the Company; (ii) a merger or consolidation in which the Company is a party; (iii) the sale, exchange, or transfer of all or substantially all of the assets of the Company; or (iv) a liquidation or dissolution of the Company. (b) A "TRANSFER OF CONTROL" shall mean an Ownership Change Event or a series of related Ownership Change Events (collectively, the "TRANSACTION") wherein the stockholders of the Company immediately before the Transaction do not retain immediately after the Transaction, in substantially the 30 same proportions as their ownership of shares of the Company's voting stock immediately before the Transaction, direct or indirect beneficial ownership of more than fifty percent (50%) of the total combined voting power of the outstanding voting stock of the Company or the corporation or corporations to which the assets of the Company were transferred (the "TRANSFEREE CORPORATION(S)"), as the case may be. For purposes of the preceding sentence, indirect beneficial ownership shall include, without limitation, an interest resulting from ownership of the voting stock of one or more corporations which, as a result of the Transaction, own the Company or the Transferee Corporation(s), as the case may be, either directly or through one or more subsidiary corporations. The Board shall have the right to determine whether multiple sales or exchanges of the voting stock of the Company or multiple Ownership Change Events are related, and its determination shall be final, binding and conclusive. 8.2 EFFECT OF TRANSFER OF CONTROL ON OPTION. In the event of a Transfer of Control, any unexercised portion of the Option shall be immediately exercisable and vested in full as of the date ten (10) days prior to the date of the Transfer of Control. Any exercise of the Option that was permissible solely by reason of this Section 8.2 shall be conditioned upon the consummation of the Transfer of Control. In addition, the surviving, continuing, successor, or purchasing corporation or parent corporation thereof, as the case may be (the "ACQUIRING CORPORATION"), may either assume the Company's rights and obligations under the Option or substitute for the Option a substantially equivalent option for the Acquiring Corporation's stock. The Option shall terminate and cease to be outstanding effective as of the date of the Transfer of Control to the extent that the Option is neither assumed or substituted for by the Acquiring Corporation in connection with the Transfer of Control nor exercised as of the date of the Transfer of Control. Notwithstanding the foregoing, shares acquired upon exercise of the Option prior to the Transfer of Control and any consideration received pursuant to the Transfer of Control with respect to such shares shall continue to be subject to all applicable provisions of this Option Agreement except as otherwise provided herein. Furthermore, notwithstanding the foregoing, if the corporation the stock of which is subject to the Option immediately prior to an Ownership Change Event described in Section 8.1(a)(i) constituting a Transfer of Control is the surviving or continuing corporation and immediately after such Ownership Change Event less than fifty percent (50%) of the total combined voting power of its voting stock is held by another corporation or by other corporations that are members of an affiliated group within the meaning of Section 1504(a) of the Code without regard to the provisions of Section 1504(b) of the Code, the Option shall not terminate. 9. ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event of any -------------------------------------------- stock dividend, stock split, reverse stock split, recapitalization, combination, reclassification, or similar change in the capital structure of the Company, appropriate adjustments shall be made in the number, Exercise Price and class of shares of stock subject to the Option. If a majority of the shares which are of the same class as the shares that are subject to the Option are exchanged for, 31 converted into, or otherwise become (whether or not pursuant to an Ownership Change Event) shares of another corporation (the "NEW SHARES"), the Board may unilaterally amend the Option to provide that the Option is exercisable for New Shares. In the event of any such amendment, the Number of Option Shares and the Exercise Price shall be adjusted in a fair and equitable manner, as determined by the Board, in its sole discretion. Notwithstanding the foregoing, any fractional share resulting from an adjustment pursuant to this Section 9 shall be rounded down to the nearest whole number, and in no event may the Exercise Price be decreased to an amount less than the par value, if any, of the stock subject to the Option. 10. RIGHTS AS A STOCKHOLDER. The Optionee shall have no rights as a ------------------------ stockholder with respect to any shares covered by the Option until the date of the issuance of a certificate for the shares for which the Option has been exercised (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such certificate is issued, except as provided in Section 9. 11. LEGENDS. The Company may at any time place legends referencing any ------- applicable federal, state or foreign securities law restrictions on all certificates representing shares of stock subject to the provisions of this Option Agreement. The Optionee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Optionee in order to carry out the provisions of this Section. 12. BINDING EFFECT. Subject to the restrictions on transfer set forth -------------- herein, this Option Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs, executors, administrators, successors and assigns. 13. TERMINATION OR AMENDMENT. The Board may terminate or amend the Plan ------------------------ or the Option at any time; provided, however, that no such termination or amendment may adversely affect the Option or any unexercised portion hereof without the consent of the Optionee unless such termination or amendment is necessary to comply with any applicable law or government regulation. No amendment or addition to this Option Agreement shall be effective unless in writing. 14. INTEGRATED AGREEMENT. This Option Agreement constitutes the entire -------------------- understanding and agreement of the Optionee and the Participating Company Group with respect to the subject matter contained herein, and there are no agreements, understandings, restrictions, representations, or warranties among the Optionee and the Participating Company Group with respect to such subject matter other 32 than those as set forth or provided for herein.

any duly appointed Committee of the Board.  All questions of interpretation of
the Plan or of any Purchase Right shall be determined by the Board and shall be
final and binding upon all persons having an interest in the Plan or such
Purchase Right.  Subject to the provisions of the Plan, the Board shall
determine all of the relevant terms and conditions of Purchase Rights granted
pursuant to the Plan; provided, however, that all Participants granted Purchase
Rights pursuant to the Plan shall have the same rights and privileges within the
meaning of Section 423(b)(5) of the Code.  All expenses incurred in connection
with the administration of the Plan shall be paid by the Company.

     4.  SHARES SUBJECT TO PLAN.
         ---------------------- 

         4.1  MAXIMUM NUMBER OF SHARES ISSUABLE. Subject to adjustment as
provided in Section 4.2, the maximum aggregate number of shares of Stock that
may be issued under the Plan shall be two hundred fifty thousand (250,000) (on a
post-split basis following the two-for-three reverse stock split of the Stock
approved by the Board on April 30, 1996) and shall consist of authorized but
unissued or reacquired shares of the Stock, or any combination thereof. If an
outstanding Purchase Right for any reason expires or is terminated or canceled,
the shares of Stock allocable to the unexercised portion of such Purchase Right
shall again be available for issuance under the Plan.

         4.2  ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event of any
stock dividend, stock split, reverse stock split, recapitalization, combination,
reclassification or similar change in the capital structure of the Company, or
in the event of any merger (including a merger effected for the purpose of
changing the Company's domicile), sale of assets or other reorganization in
which the Company is a party, appropriate adjustments shall be made in the
number and class of shares subject to the Plan, to the Per Offering Share Limit
set forth in Section 8.1 and to each Purchase Right and in the Purchase Price.

     5.  ELIGIBILITY.
         ----------- 

         5.1  EMPLOYEES ELIGIBLE TO PARTICIPATE. Any Employee of a Participating
Company is eligible to participate in the Plan except the following:

                 (a) Employees who are customarily employed by the Participating
Company Group for twenty (20) hours or less per week;

                                       4

 
                 (b) Employees who are customarily employed by the Participating
Company Group for not more than five (5) months in any calendar year; and

                 (c) Employees who own or hold options to purchase or who, as a
result of participation in the Plan, would own or hold options to purchase,
stock of the Company or of any Parent Corporation or Subsidiary Corporation
possessing five percent (5%) or more of the total combined voting power or value
of all classes of stock of such corporation within the meaning of Section
423(b)(3) of the Code.

         5.2  LEASED EMPLOYEES EXCLUDED. Notwithstanding anything herein to the
contrary, any individual performing services for a Participating Company solely
through a leasing agency or employment agency shall not be deemed an "Employee"
of such Participating Company.

     6.   OFFERINGS.
          --------- 

          6.1 OFFERING PERIODS. Except as otherwise set forth below, the Plan
shall be implemented by sequential Offerings of approximately twenty-four (24)
months duration (an "OFFERING PERIOD"); provided, however that the first
Offering Period shall commence on the Effective Date and end on August 31, 1998
(the "INITIAL OFFERING PERIOD"). Subsequent Offerings shall commence on the
first days of March and September of each year and end on the last days of the
second February and August, respectively, occurring thereafter. Notwithstanding
the foregoing, the Board may establish a different term for one or more
Offerings or different commencing or ending dates for such Offerings; provided,
however, that no Offering may exceed a term of twenty-seven (27) months. An
Employee who becomes an Eligible Employee after an Offering Period has commenced
shall not be eligible to participate in such Offering but may participate in any
subsequent Offering provided such Employee is still an Eligible Employee as of
the commencement of any such subsequent Offering. Eligible Employees may not
participate in more than one Offering at a time. In the event the first or last
day of an Offering Period is not a business day, the Company shall specify the
business day that will be deemed the first or last day, as the case may be, of
the Offering Period.

          6.2 PURCHASE PERIODS. Each Offering Period shall consist of four (4)
consecutive purchase periods of approximately six (6) months duration
(individually, a "PURCHASE PERIOD"). The Purchase Period commencing on the
Offering Date of the Initial Offering Period shall end on February 28, 1997. A
Purchase Period commencing on the first day of March shall end on the last day
of the next following August. A Purchase Period commencing on the first day of
September shall end on the last day of the next following February.
Notwithstanding the foregoing, the Board may establish a different term for one
or more Purchase Periods or different commencing or ending dates for such
Purchase

                                       5

 
Periods.  In the event the first or last day of a Purchase Period is not a
business day, the Company shall specify the business day that will be deemed the
first or last day, as the case may be, of the Purchase Period.

          6.3  GOVERNMENTAL APPROVAL; STOCKHOLDER APPROVAL. Notwithstanding any
other provision of the Plan to the contrary, any Purchase Right granted pursuant
to the Plan shall be subject to (a) obtaining all necessary governmental
approvals or qualifications of the sale or issuance of the Purchase Rights or
the shares of Stock and (b) obtaining stockholder approval of the Plan.
Notwithstanding the foregoing, stockholder approval shall not be necessary in
order to grant any Purchase Right granted in the Plan's Initial Offering Period;
provided, however, that the exercise of any such Purchase Right shall be subject
to obtaining stockholder approval of the Plan.

     7.   PARTICIPATION IN THE PLAN.
          ------------------------- 

          7.1 INITIAL PARTICIPATION. An Eligible Employee shall become a
Participant on the first Offering Date after satisfying the eligibility
requirements of Section 5 and delivering to the Company's payroll office or
other office designated by the Company not later than the close of business for
such office on the last business day before such Offering Date (the
"SUBSCRIPTION DATE") a subscription agreement indicating the Employee's election
to participate in the Plan and authorizing payroll deductions. An Eligible
Employee who does not deliver a subscription agreement to the Company's payroll
or other designated office on or before the Subscription Date shall not
participate in the Plan for that Offering Period or for any subsequent Offering
Period unless such Employee subsequently enrolls in the Plan by filing a
subscription agreement with the Company by the Subscription Date for such
subsequent Offering Period. The Company may, from time to time, change the
Subscription Date as deemed advisable by the Company in its sole discretion for
proper administration of the Plan.

          7.2 CONTINUED PARTICIPATION. A Participant shall automatically
participate in the Offering Period commencing immediately after the final
Purchase Date of each Offering Period in which the Participant participates
until such time as such Participant (a) ceases to be an Eligible Employee, (b)
withdraws from the Plan pursuant to Section 14.2 or (c) terminates employment as
provided in Section 15. If a Participant automatically may participate in a
subsequent Offering Period pursuant to this Section 7.2, then the Participant is
not required to file any additional subscription agreement for such subsequent
Offering Period in order to continue participation in the Plan. However, a
Participant may file a subscription agreement with respect to a subsequent
Offering Period if the Participant desires to change any of the Participant's
elections contained in the Participant's then effective subscription agreement.

                                       6

 
     8.   RIGHT TO PURCHASE SHARES.
          ------------------------ 

          8.1 PURCHASE RIGHT. Except as set forth below, during an Offering
Period each Participant in such Offering Period shall have a Purchase Right
consisting of the right to purchase that number of whole shares of Stock arrived
at by dividing Fifty Thousand Dollars ($50,000) by the Fair Market Value of a
share of Stock on the Offering Date of such Offering Period; provided, however,
that such number shall not exceed five thousand (5,000) shares (the "Per
Offering Share Limit"). Shares of Stock may only be purchased through a
Participant's payroll deductions pursuant to Section 10.

          8.2 PRO RATA ADJUSTMENT OF PURCHASE RIGHT. Notwithstanding the
foregoing, if the Board shall establish an Offering Period of less than twenty-
three and one-half (23 1/2) months or more than twenty-four and one-half (24
1/2) months in duration, (a) the dollar amount in Section 8.1 shall be
determined by multiplying $2,083.33 by the number of months in the Offering
Period and rounding to the nearest whole dollar, and (b) the Per Offering Share
Limit shall be determined by multiplying 208.33 shares by the number of months
in the Offering Period and rounding to the nearest whole share. For purposes of
the preceding sentence, fractional months shall be rounded to the nearest whole
month.

     9.  PURCHASE PRICE.  The Purchase Price at which each share of Stock may be
         --------------                                                         
acquired in a given Offering Period pursuant to the exercise of all or any
portion of a Purchase Right granted under the Plan shall be set by the Board;
provided, however, that the Purchase Price shall not be less than eighty-five
percent (85%) of the lesser of (a) the Fair Market Value of a share of Stock on
the Offering Date of the Offering Period, or (b) the Fair Market Value of a
share of Stock on the Purchase Date of the Offering Period.  Unless otherwise
provided by the Board prior to the commencement of an Offering Period, the
Purchase Price for that Offering Period shall be eighty-five percent (85%) of
the lesser of (a) the Fair Market Value of a share of Stock on the Offering Date
of the Offering Period, or (b) the Fair Market Value of a share of Stock on the
Purchase Date of the Offering Period.

     10.  ACCUMULATION OF PURCHASE PRICE THROUGH PAYROLL DEDUCTION.  Shares of
          --------------------------------------------------------            
Stock which are acquired pursuant to the exercise of all or any portion of a
Purchase Right for an Offering Period may be paid for only by means of payroll
deductions from the Participant's Compensation accumulated during the Offering
Period.  Except as set forth below, the amount of Compensation to be deducted
from a Participant's Compensation during each pay period shall be determined by
the Participant's subscription agreement.

          10.1 COMMENCEMENT OF PAYROLL DEDUCTIONS. Payroll deductions shall
commence on the first payday following the Offering Date and shall continue to
the end of the Offering Period unless sooner altered or terminated as provided
in the Plan.

                                       7

 
          10.2 LIMITATIONS ON PAYROLL DEDUCTIONS. The amount of payroll
deductions with respect to the Plan for any Participant during any pay period
shall be in one percent (1%) increments not to exceed ten percent (10%) of the
Participant's Compensation for such pay period. Notwithstanding the foregoing,
the Board may change the limits on payroll deductions effective as of a future
Offering Date, as determined by the Board. Amounts deducted from Compensation
shall be reduced by any amounts contributed by the Participant and applied to
the purchase of Company stock pursuant to any other employee stock purchase plan
qualifying under Section 423 of the Code.

          10.3 ELECTION TO DECREASE OR STOP PAYROLL DEDUCTIONS. During an
Offering Period, a Participant may elect to decrease the amount deducted or stop
deductions from his or her Compensation by filing an amended subscription
agreement with the Company on or before the "Change Notice Date." The "CHANGE
NOTICE DATE" shall initially be the seventh (7th) day prior to the end of the
first pay period for which such election is to be effective; however, the
Company may change such Change Notice Date from time to time. A Participant may
not elect to increase the amount deducted from the Participant's Compensation
during an Offering Period.

          10.4 PARTICIPANT ACCOUNTS. Individual Plan accounts shall be
maintained for each Participant. All payroll deductions from a Participant's
Compensation shall be credited to such account and shall be deposited with the
general funds of the Company. All payroll deductions received or held by the
Company may be used by the Company for any corporate purpose.

          10.5 NO INTEREST PAID. Interest shall not be paid on sums deducted
from a Participant's Compensation pursuant to the Plan.

          10.6 COMPANY ESTABLISHED PROCEDURES. The Company may, from time to
time, establish or change (a) a minimum required payroll deduction amount for
participation in an Offering, (b) limitations on the frequency or number of
changes in the rate of payroll deduction during an Offering, (c) an exchange
ratio applicable to amounts withheld in a currency other than U.S. dollars, (d)
payroll deduction in excess of or less than the amount designated by a
Participant in order to adjust for delays or mistakes in the Company's
processing of subscription agreements, (e) the date(s) and manner by which the
Fair Market Value of a share of Stock is determined for purposes of
administration of the Plan, or (f) such other limitations or procedures as
deemed advisable by the Company in the Company's sole discretion which are
consistent with the Plan and in accordance with the requirements of Section 423
of the Code.

     11. PURCHASE OF SHARES.
         ------------------ 

          11.1 EXERCISE OF PURCHASE RIGHT. On each Purchase Date of an Offering
Period, each Participant who has not withdrawn from the Offering or

                                       8

 
whose participation in the Offering has not terminated on or before such
Purchase Date shall automatically acquire pursuant to the exercise of the
Participant's Purchase Right the number of whole shares of Stock arrived at by
dividing the total amount of the Participant's accumulated payroll deductions
for the Purchase Period by the Purchase Price; provided, however, in no event
shall the number of shares purchased by the Participant during an Offering
Period exceed the number of shares subject to the Participant's Purchase Right.
No shares of Stock shall be purchased on a Purchase Date on behalf of a
Participant whose participation in the Offering or the Plan has terminated on or
before such Purchase Date.

          11.2 RETURN OF CASH BALANCE. Any cash balance remaining in the
Participant's Plan account shall be refunded to the Participant as soon as
practicable after the Purchase Date. In the event the cash to be returned to a
Participant pursuant to the preceding sentence is an amount less than the amount
necessary to purchase a whole share of Stock, the Company may establish
procedures whereby such cash is maintained in the Participant's Plan account and
applied toward the purchase of shares of Stock in the subsequent Purchase Period
or Offering Period.

          11.3 TAX WITHHOLDING. At the time a Participant's Purchase Right is
exercised, in whole or in part, or at the time a Participant disposes of some or
all of the shares of Stock he or she acquires under the Plan, the Participant
shall make adequate provision for the foreign, federal, state and local tax
withholding obligations of the Participating Company Group, if any, which arise
upon exercise of the Purchase Right or upon such disposition of shares,
respectively. The Participating Company Group may, but shall not be obligated
to, withhold from the Participant's compensation the amount necessary to meet
such withholding obligations.

          11.4 EXPIRATION OF PURCHASE RIGHT. Any portion of a Participant's
Purchase Right remaining unexercised after the end of the Offering Period to
which such Purchase Right relates shall expire immediately upon the end of such
Offering Period.

     12.  MARKET STAND-OFF PERIOD.  No Participant shall, for a period of 180
          -----------------------                                            
days following the Purchase Date upon which a share of Stock is acquired,
directly or indirectly sell, offer to sell, contract to sell (including, without
limitation, any short sale), grant any option to purchase or otherwise transfer
or dispose (other than to donees who agree to be similarly bound) of such share
of Stock.  The restriction on transfer of this Section 12 shall terminate
immediately upon a Transfer of Control, as defined in Section 16.

     13.  LIMITATIONS ON PURCHASE OF SHARES; RIGHTS AS A STOCKHOLDER.
          ---------------------------------------------------------- 

          13.1 FAIR MARKET VALUE LIMITATION. Notwithstanding any other provision
of the Plan, no Participant shall be entitled to purchase shares of Stock

                                       9

 
under the Plan (or any other employee stock purchase plan which is intended to
meet the requirements of Section 423 of the Code sponsored by the Company or a
Parent Corporation or Subsidiary Corporation at a rate which exceeds $25,000 in
Fair Market Value, which Fair Market Value is determined for shares purchased
during a given Offering Period as of the Offering Date for such Offering Period
(or such other limit as may be imposed by the Code), for each calendar year in
which the Participant participates in the Plan (or any other employee stock
purchase plan described in this sentence).

          13.2 PRO RATA ALLOCATION. In the event the number of shares of Stock
which might be purchased by all Participants in the Plan exceeds the number of
shares of Stock available in the Plan, the Company shall make a pro rata
allocation of the remaining shares in as uniform a manner as shall be
practicable and as the Company shall determine to be equitable.

          13.3 RIGHTS AS A STOCKHOLDER AND EMPLOYEE. A Participant shall have no
rights as a stockholder by virtue of the Participant's participation in the Plan
until the date of the issuance of a stock certificate for the shares of Stock
being purchased pursuant to the exercise of the Participant's Purchase Right. No
adjustment shall be made for cash dividends or distributions or other rights for
which the record date is prior to the date such stock certificate is issued.
Nothing herein shall confer upon a Participant any right to continue in the
employ of the Participating Company Group or interfere in any way with any right
of the Participating Company Group to terminate the Participant's employment at
any time.

     14.  WITHDRAWAL.
          ---------- 

          14.1 WITHDRAWAL FROM AN OFFERING. A Participant may withdraw from an
Offering by signing and delivering to the Company's payroll or other designated
office a written notice of withdrawal on a form provided by the Company for such
purpose. Such withdrawal may be elected at any time prior to the end of an
Offering Period; provided, however, if a Participant withdraws after the
Purchase Date for a Purchase Period of an Offering, the withdrawal shall not
affect shares of Stock acquired by the Participant in such Purchase Period.
Unless otherwise indicated, withdrawal from an Offering shall not result in a
withdrawal from the Plan or any succeeding Offering therein. By withdrawing from
an Offering effective as of the close of a given Purchase Date, a Participant
may have shares of Stock purchased on such Purchase Date and immediately
commence participation in the new Offering commencing immediately after such
Purchase Date. A Participant is prohibited from again participating in an
Offering at any time following withdrawal from such Offering. The Company may
impose, from time to time, a requirement that the notice of withdrawal be on
file with the Company's payroll office or other designated office for a
reasonable period prior to the effectiveness of the Participant's withdrawal
from an Offering.

                                       10

 
          14.2 WITHDRAWAL FROM THE PLAN. A Participant may withdraw from the
Plan by signing and delivering to the Company's payroll office or other
designated office a written notice of withdrawal on a form provided by the
Company for such purpose. Withdrawals made after a Purchase Date shall not
affect shares of Stock acquired by the Participant on such Purchase Date. In the
event a Participant voluntarily elects to withdraw from the Plan, the
Participant may not resume participation in the Plan during the same Offering
Period, but may participate in any subsequent Offering under the Plan by again
satisfying the requirements of Sections 5 and 7.1. The Company may impose, from
time to time, a requirement that the notice of withdrawal be on file with the
Company's payroll office or other designated office for a reasonable period
prior to the effectiveness of the Participant's withdrawal from the Plan.

          14.3 RETURN OF PAYROLL DEDUCTIONS. Upon a Participant's withdrawal
from an Offering or the Plan pursuant to Sections 14.1 or 14.2, respectively,
the Participant's accumulated payroll deductions which have not been applied
toward the purchase of shares of Stock shall be returned as soon as practicable
after the withdrawal, without the payment of any interest, to the Participant,
and the Participant's interest in the Offering or the Plan, as applicable, shall
terminate. Such accumulated payroll deductions may not be applied to any other
Offering under the Plan.

          14.4 AUTOMATIC WITHDRAWAL FROM AN OFFERING. If the Fair Market Value
of a share of Stock on a Purchase Date of an Offering (other than the final
Purchase Date of such Offering) is less than the Fair Market Value of a share of
Stock on the Offering Date for such Offering, then every Participant shall
automatically (a) be withdrawn from such Offering at the close of such Purchase
Date and after the acquisition of shares of Stock for such Purchase Period and
(b) be enrolled in the Offering commencing on the first business day subsequent
to such Purchase Period. A Participant may elect not to be automatically
withdrawn from an Offering Period pursuant to this Section 14.4 by delivering to
the Company not later than the close of business on the last day before the
Purchase Date a written notice indicating such election.


                                       11

 
     15.  TERMINATION OF EMPLOYMENT OR ELIGIBILITY.  Termination of a
          ----------------------------------------                   
Participant's employment with a Participating Company for any reason, including
retirement, disability or death or the failure of a Participant to remain an
Eligible Employee, shall terminate the Participant's participation in the Plan
immediately.  In such event, the payroll deductions credited to the
Participant's Plan account since the last Purchase Date shall, as soon as
practicable, be returned to the Participant or, in the case of the Participant's
death, to the Participant's legal representative, and all of the Participant's
rights under the Plan shall terminate.  Interest shall not be paid on sums
returned to a Participant pursuant to this Section 15.  A Participant whose
participation has been so terminated may again become eligible to participate in
the Plan by again satisfying the requirements of Sections 5 and 7.1.

     16.   TRANSFER OF CONTROL.
           ------------------- 

          16.1   DEFINITIONS.

                 (a) An "OWNERSHIP CHANGE EVENT" shall be deemed to have
occurred if any of the following occurs with respect to the Company: (i) the
direct or indirect sale or exchange in a single or series of related
transactions by the stockholders of the Company of more than fifty percent (50%)
of the voting stock of the Company; (ii) a merger or consolidation in which the
Company a party; (iii) the sale, exchange, or transfer of all or substantially
all of the assets of the Company; or (iv) a liquidation or dissolution of the
Company.
                 (b) A "TRANSFER OF CONTROL" shall mean an Ownership Change
Event or a series of related Ownership Change Events (collectively, the
"TRANSACTION") wherein the stockholders of the Company immediately before the
Transaction do not retain immediately after the Transaction, in substantially
the same proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "TRANSFEREE
CORPORATION(S)"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting stock of one or more corporations which,
as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the case may be, either directly or through one or more
subsidiary corporations. The Board shall have the right to determine whether
multiple sales or exchanges of the voting stock of the Company or multiple
Ownership Change Events are related, and its determination shall be final,
binding and conclusive.

          16.2 EFFECT OF TRANSFER OF CONTROL ON PURCHASE RIGHTS. In the event of
a Transfer of Control, the surviving, continuing, successor, or purchasing
corporation or parent corporation thereof, as the case may be (the "ACQUIRING

                                       12

 
CORPORATION"), may assume the Company's rights and obligations under the Plan or
substitute substantially equivalent Purchase Rights for stock of the Acquiring
Corporation.  If the Acquiring Corporation elects not to assume or substitute
for the outstanding Purchase Rights, the Board may, in its sole discretion and
notwithstanding any other provision herein to the contrary, adjust the Purchase
Date of the then current Purchase Period to a date on or before the date of the
Transfer of Control, but shall not adjust the number of shares of Stock subject
to any Purchase Right.  All Purchase Rights which are neither assumed or
substituted for by the Acquiring Corporation in connection with the Transfer of
Control nor exercised as of the date of the Transfer of Control shall terminate
and cease to be outstanding effective as of the date of the Transfer of Control.
Notwithstanding the foregoing, if the corporation the stock of which is subject
to the outstanding Purchase Rights immediately prior to an Ownership Change
Event described in Section 16.1(a)(i) constituting a Transfer of Control is the
surviving or continuing corporation and immediately after such Ownership Change
Event less than fifty percent (50%) of the total combined voting power of its
voting stock is held by another corporation or by other corporations that are
members of an affiliated group within the meaning of section 1504(a) of the Code
without regard to the provisions of section 1504(b) of the Code, the outstanding
Purchase Rights shall not terminate unless the Board otherwise provides in its
sole discretion.

     17.  NONTRANSFERABILITY OF PURCHASE RIGHTS.  A Purchase Right may not be
          -------------------------------------                              
transferred in any manner otherwise than by will or the laws of descent and
distribution and shall be exercisable during the lifetime of the Participant
only by the Participant.  The Company, in its absolute discretion, may impose
such restrictions on the transferability of the shares purchasable upon the
exercise of a Purchase Right as it deems appropriate and any such restriction
shall be set forth in the respective subscription agreement and may be referred
to on the certificates evidencing such shares.

     18.  REPORTS.  Each Participant who exercised all or part of his or her
          -------                                                           
Purchase Right for a Purchase Period shall receive, as soon as practicable after
the Purchase Date of such Purchase Period, a report of such Participant's Plan
account setting forth the total payroll deductions accumulated, the number of
shares of Stock purchased, the Purchase Price for such shares, the date of
purchase and the remaining cash balance to be refunded or retained in the
Participant's Plan account pursuant to Section 11.2, if any.  Each Participant
shall be provided information concerning the Company equivalent to that
information generally made available to the Company's common stockholders.

     19.  RESTRICTION ON ISSUANCE OF SHARES.  The issuance of shares under the
          ---------------------------------                                   
Plan shall be subject to compliance with all applicable requirements of foreign,
federal or state law with respect to such securities.  A Purchase Right may not
be exercised if the issuance of shares upon such exercise would constitute a
violation of any applicable foreign, federal or state securities laws or other
law or regulations.  In addition, no Purchase Right may be exercised unless (a)
a

                                       13

 
registration statement under the Securities Act of 1933, as amended, shall at
the time of exercise of the Purchase Right be in effect with respect to the
shares issuable upon exercise of the Purchase Right, or (b) in the opinion of
legal counsel to the Company, the shares issuable upon exercise of the Purchase
Right may be issued in accordance with the terms of an applicable exemption from
the registration requirements of said Act.  The inability of the Company to
obtain from any regulatory body having jurisdiction the authority, if any,
deemed by the Company's legal counsel to be necessary to the lawful issuance and
sale of any shares under the Plan shall relieve the Company of any liability in
respect of the failure to issue or sell such shares as to which such requisite
authority shall not have been obtained.  As a condition to the exercise of a
Purchase Right, the Company may require the Participant to satisfy any
qualifications that may be necessary or appropriate, to evidence compliance with
any applicable law or regulation, and to make any representation or warranty
with respect thereto as may be requested by the Company.

     20.  LEGENDS.  The Company may at any time place legends or other
          -------                                                     
identifying symbols referencing any applicable foreign, federal or state
securities law restrictions or any provision convenient in the administration of
the Plan on some or all of the certificates representing shares of Stock issued
under the Plan.  The Participant shall, at the request of the Company, promptly
present to the Company any and all certificates representing shares acquired
pursuant to a Purchase Right in the possession of the Participant in order to
carry out the provisions of this Section.  Unless otherwise specified by the
Company, legends placed on such certificates may include but shall not be
limited to the following:

          "THE SHARES EVIDENCED BY THIS CERTIFICATE WERE ISSUED BY THE
CORPORATION TO THE REGISTERED HOLDER UPON THE PURCHASE OF SHARES UNDER AN
EMPLOYEE STOCK PURCHASE PLAN AS DEFINED IN SECTION 423 OF THE INTERNAL REVENUE
CODE OF 1986, AS AMENDED.  THE TRANSFER AGENT FOR THE SHARES EVIDENCED HEREBY
SHALL NOTIFY THE CORPORATION IMMEDIATELY OF ANY TRANSFER OF THE SHARES BY THE
REGISTERED HOLDER HEREOF MADE ON OR BEFORE ______________, 19__.  THE REGISTERED
HOLDER SHALL HOLD ALL SHARES PURCHASED UNDER THE PLAN IN THE REGISTERED HOLDER'S
NAME (AND NOT IN THE NAME OF ANY NOMINEE) PRIOR TO THIS DATE."

          "THE SHARES EVIDENCED BY THIS CERTIFICATE WERE ISSUED BY THE
CORPORATION TO THE REGISTERED HOLDER UPON THE PURCHASE OF SHARES UNDER AN
EMPLOYEE STOCK PURCHASE PLAN, PURSUANT TO WHICH THE SHARES MAY NOT BE SOLD,
TRANSFERRED, OR DISPOSED OF (OTHER THAN TO DONEES WHO AGREE TO BE SIMILARLY
BOUND) UNTIL ___________, 19__."

     21.  NOTIFICATION OF SALE OF SHARES.  The Company may require the
          ------------------------------                              
Participant to give the Company prompt notice of any disposition of shares

                                       14

 
acquired by exercise of a Purchase Right within two years from the date of
granting such Purchase Right or one year from the date of exercise of such
Purchase Right.  The Company may require that until such time as a Participant
disposes of shares acquired upon exercise of a Purchase Right, the Participant
shall hold all such shares in the Participant's name (and not in the name of any
nominee) until the lapse of the time periods with respect to such Purchase Right
referred to in the preceding sentence.  The Company may direct that the
certificates evidencing shares acquired by exercise of a Purchase Right refer to
such requirement to give prompt notice of disposition.

     22.  AMENDMENT OR TERMINATION OF THE PLAN.  The Board may at any time amend
          ------------------------------------                                  
or terminate the Plan, except that (a) such termination shall not affect
Purchase Rights previously granted under the Plan, except as permitted under the
Plan, and (b) no amendment may adversely affect a Purchase Right previously
granted under the Plan (except to the extent permitted by the Plan or as may be
necessary to qualify the Plan as an employee stock purchase plan pursuant to
Section 423 of the Code or to obtain qualification or registration of the shares
of Stock under applicable foreign, federal or state securities laws).  In
addition, an amendment to the Plan must be approved by the stockholders of the
Company within twelve (12) months of the adoption of such amendment if such
amendment would authorize the sale of more shares than are authorized for
issuance under the Plan or would change the definition of the corporations that
may be designated by the Board as Participating Companies.

     IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies that
the foregoing AASTROM Biosciences, Inc. 1996 Employee Stock Purchase Plan was
duly adopted by the Board of Directors of the Company on April 30, 1996.

                             SUBSCRIPTION AGREEMENT



[_]  Original Application


[_]  Change in Percentage of Payroll Deductions

     I hereby elect to participate in the 1996 Employee Stock Purchase Plan (the
"Plan") of AASTROM Biosciences, Inc. (the "COMPANY") and subscribe to purchase
shares of the Company's common stock as determined in accordance with the terms
of the Plan.

     I hereby authorize payroll deductions in the amount of ______________
percent (in 1% increments not to exceed 10%) of my "COMPENSATION" (as defined in
the Plan) from each paycheck throughout the "OFFERING PERIOD" (as defined in the
Plan) in accordance with the terms of the Plan.  I understand that these payroll
deductions will be accumulated for the purchase of shares of common stock of the
Company at the applicable purchase price determined in accordance with the Plan.
I further understand that, except as otherwise set forth in the Plan, shares
will be purchased for me automatically on the last day of each Purchase Period
unless I withdraw from the Plan or from the Offering by giving written notice to
the Company or unless I terminate employment.

     I further understand that I will automatically participate in each
subsequent Offering which commences immediately after the last day of an
Offering in which I am participating under the Plan until such time as I file
with the Company a notice of withdrawal from the Plan on such form as may be
established from time to time by the Company or I terminate employment.

     Shares purchased for me under the Plan should be issued in the name set
forth below.  (I understand that shares may be issued either in my name alone or
together with my spouse as community property or in joint tenancy.)

          NAME:
                   -------------------------------------------------------------
          ADDRESS:
                   -------------------------------------------------------------

          MY SOCIAL SECURITY NUMBER:
                                     -------------------------------------------

     I hereby authorize withholding from my compensation in order to satisfy the
foreign, federal, state and local tax withholding obligations, if any, which may
arise upon my purchase of shares under the Plan and/or upon my disposition of
shares I acquired under the Plan.  I hereby agree that until I dispose of the
shares, unless otherwise permitted by the Company, I will hold all shares I
acquire under the Plan in the name entered above (and not in the name of any
nominee) for at least two (2) years from the first day of the Offering Period in
which, and at least one (1) year from the Purchase Date on which, I acquired
such shares.  I further agree that I will promptly notify the Chief Financial
Officer of the Company in writing of any transfer of such shares prior to the
end of the periods referred to in the preceding sentence.

     I am familiar with the provisions of the Plan and hereby agree to
participate in the Plan subject to all of the provisions thereof.  I understand
that any shares purchased under the Plan are subject to a 180-day "market stand-
off" period, as provided in the Plan.  I understand that the Board of Directors
of the Company reserves the right to amend the Plan and my right to purchase
stock under the Plan as may be necessary to qualify the Plan as an employee
stock purchase plan as defined in section 423 of the Internal Revenue Code of
1986, as amended, or to obtain qualification or registration of the Company's
common stock to be issued out of the Plan under applicable foreign, federal and
state securities laws.  I understand that the effectiveness of this subscription
agreement is dependent upon my eligibility to participate in the Plan.

                             Employment Agreement


This Employment Agreement (the "Agreement") is entered into as of __________ 
1996, by and between AASTROM BIOSCIENCES, INC., a Michigan corporation 
("Employer") and [name] ("Employee").

     NOW, THEREFORE, the parties agree as follows:

     1.    EMPLOYMENT Employer hereby engages Employee, and Employee hereby 
accepts such engagement, upon the terms and conditions set forth herein.

     2.    DUTIES Employee is engaged as an [position]. Employee shall perform 
faithfully and diligently the duties customarily performed by persons in the 
position for which employee is engaged, together with such other reasonable and 
appropriate duties as Employer shall designate from time to time. Employee shall
devote Employee's full business time and efforts to the rendition of such 
services and to the performance of such duties. As a full-time employee of 
Employer, Employee shall not be entitled to provide consulting services or other
business or scientific services to any other party, without the prior written 
consent of Employer.

     3.    COMPENSATION

           3.1   BASE SALARY During the term of this Agreement, as compensation

[salary written] Dollars ($[salary]), payable in arrears in equal bi-weekly

long and mutually rewarding employment relationship, either party may terminate 
this Agreement, without cause, upon fourteen (14) days' prior written notice 
delivered to the other. It is expressly understood and agreed that the 
employment relationship is "at will", and with no agreement for employment for 
any specified term, and with no agreement for employment for so long as Employee
performs satisfactorily. Provided, however, before Employer exercises this right
of termination at will, Employer shall first either (i) discuss with Employee 
the needs of Employer and why Employee no longer meets those needs, or (ii) 
discuss with Employee any concerns or dissatisfactions which Employer has with 
Employee's performance, and give to Employee a reasonable 


 

Employment Agreement

opportunity to remedy those concerns or dissatisfactions, to the reasonable 
satisfaction of Employer.

           4.3   TERMINATION FOR CAUSE Either party may terminate this 
employment relationship immediately upon notice to the other party in the event 
of any good cause, such as a default, dishonesty, neglect of duties, failure to 
perform by the other party, or death or disability of Employee.

           4.4   PAYMENT OF COMPENSATION UPON TERMINATION Upon termination for 
cause, Employee shall be entitled to the compensation set forth as "base salary"
herein, prorated to the effective date of such termination as full compensation 
for any and all claims of Employee under this Agreement.

           5.1   CUSTOMARY FRINGE BENEFITS Employee shall be entitled to such 
fringe benefits as Employer customarily makes available to employees of Employer
engaged in the same or similar position as Employee ("Fringe Benefits"). Such 
Fringe Benefits may include vacation leave, sick leave, and health insurance 
coverage. Employer reserves the right to change the Fringe Benefits on a 
prospective basis, at any time, effective upon delivery of written notice to 
Employee.

           5.2   ACCUMULATION Employee shall not earn and accumulate unused 
vacation in excess of Fifteen (15) days. Employee shall not earn and accumulate 
sick leave or other Fringe Benefits in excess of an unused amount equal to twice

receive payments in lieu of said Fringe Benefits, other than for unused vacation
leave earned and accumulated at the time the employment relationship terminates.

     6.    INVENTIONS, TRADE SECRETS AND CONFIDENTIALITY

           6.1   DEFINITIONS

                 6.1.1 Invention Defined. As used herein "Invention" means 
inventions, discoveries, concepts, and ideas, whether patentable or 
copyrightable or not, including but not limited to processes, methods, formulas,
techniques, materials, devices, designs, programs (including computer programs),
computer graphics, apparatus, products, as well as improvements thereof or 
know-how related thereto, relating to any present or anticipated business or 
activities of Employer.

                 6.1.2 Trade Secret Defined. As used herein "Trade Secret" 
means, without limitation, any document or information relating to Employer's 
products, processes or services, including documents and information relating to
Inventions, and to the research, development, engineering or manufacture of 
Inventions, and to Employer's purchasing, customer or supplier lists, which 
documents or information have been disclosed to Employee or known to 

 
 
Employment Agreement
Page 3

Employee as a consequence of or through Employee's employment by Employer 
(including documents, information or Inventions conceived, originated, 
discovered or developed by Employee), which is not generally known in the 
relevant trade or industry.

           6.2   INVENTIONS

                 6.2.1 Disclosure. Employee shall disclose promptly to Employer 
each Invention, whether or not reduced to practice, which is conceived or 
learned by Employee (either alone or jointly with others) during the term of his
employment with Employer. Employee shall disclose in confidence to Employer all 
patent applications filed by or on behalf of Employee during the term of his 
employment and for a period of three (3) years thereafter. Any disclosure of an 
Invention, or any patent application, made within one (1) year after termination
of employment shall be presumed to relate to an Invention made during Employee's
term of Employment with Employer, unless Employee clearly proves otherwise.

                 6.2.2 Employer Property; Assignment. Employee acknowledges and 
agrees that all Inventions which are discovered, conceived, developed, made, 
produced or prepared by Employee (alone or in conjunction with others) during 
the duration of Employee's employment with Employer shall be the sole property 
of Employer. Said property rights of Employer include without limitation all 
domestic and foreign patent rights, rights of registration or other protection 
under the patent and copyright laws, and all other rights pertaining to the 
Inventions. Employee further agrees that all services, products and Inventions 
that directly or indirectly result from engagement with Company shall be deemed 
"works for hire" as that term is defined in Title 17 of the United States Codes,
and accordingly all rights associated therewith shall vest in the Company. 
Notwithstanding the foregoing, Employee hereby assigns to Employer all of 
Employee's right, title and interest in any such services, products and 
Inventions, in the event any such services, products and Inventions shall be 
determined not to constitute "works for hire."

                 6.2.3 Exclusion Notice. The Assignment by Employee of 
Inventions under this Agreement does not apply to any Inventions which are owned
or controlled by Employee prior to the commencement of employment of Employee by
Employer (all of which are set forth on Exhibit "A" hereto). Additionally,
Employee is not required to assign an idea or invention where the invention or
idea meets all of the following criteria; namely if the invention
           ---
or idea: (i) was created or conceived without the use of any of Employer's 
equipment, supplies, facilities, or trade secret information, and (ii) was 
developed entirely on Employee's own time, and (iii) does not relate to the 
business of Employer, and (iv) does not relate to Employer's actual or 
demonstrably anticipated research or development, and (v) does not result from 
any work performed by Employee for Employer.

                 6.2.4 Patents and Copyrights; Attorney-in Fact. Both before and
after termination of this Agreement (and with reasonable compensation paid by 
Employer to Employee after termination), Employee


 
 
Employment Agreement
Page 4

agrees to assist the Employer to apply for, obtain and enforce patents on, and 
to apply for, obtain and enforce copyright protection and registration of, the 
Inventions described in Section 6.2.2 in any and all countries. To that end, 
Employee shall (at Employer's request) without limitation, testify in any 
proceeding, and execute any documents and assignments determined to be necessary
or convenient for use in applying for, obtaining, registering and enforcing
patent or copyright protection involving any of the Inventions. Employee hereby
irrevocably appoints Employer, and its duly authorized officers and agents, as
Employee's agent and attorney-in-fact, to act for and in behalf of Employee in
filing all patent applications, applications for copyright protection and
registration, amendments, renewals, and all other appropriate documents in any
way related to the Inventions described in Section 6.2.2.

           6.3   TRADE SECRETS

                 6.3.1 Acknowledgement of Proprietary Interest. Employee 
recognizes the proprietary interest of Employer in any Trade Secrets of 
Employer. Employee acknowledges and agrees that any and all Trade Secrets of 
Employer, whether developed by Employee alone or in conjunction with others or 
otherwise, shall be and are the property of Employer.

                 6.3.2 Covenant Not to Divulge Trade Secrets. Employee 
acknowledges and agrees that Employer is entitled to prevent the disclosure of 
Trade Secrets of Employer. As a portion of the consideration for the employment 
of Employee and for the compensation being paid to Employee by Employer, 
Employee agrees at all times during the term of the employment by Employer and 
thereafter to hold in strictest confidence, and not to use, disclose or allow to
be disclosed to any person, firm, or corporation, Trade Secrets of Employer, 
including Trade Secrets developed by Employee, other than disclosures to persons
engaged by Employer to further the business of Employer, and other than use in 
the pursuit of the business of Employer.

                 6.3.3 Confidential Information of Others. Employee represents 
and warrants that if Employee has any confidential information belonging to 
others, Employee will not use or disclose to Employer any such information or 
documents. Employee represents that his employment with Employer will not 
require him to violate any obligation to or confidence with any other party.

           6.4   NO ADVERSE USE Employee will not at any time use Employer's 
Trade Secrets or Inventions in any manner which may directly or indirectly have 
an adverse effect upon Employer's business, nor will Employee perform any acts 
which would tend to reduce Employer's proprietary value in Employer's Trade 
Secrets or Inventions.

           6.5   RETURN OF MATERIALS AT TERMINATION In the event of any 
termination of Employee's employment, Employee will promptly deliver to Employer
all materials, property, documents, data, and other information belonging to 
Employer or pertaining to Trade Secrets or Inventions. Employee


 
 
Employment Agreement
Page 5

shall not take any materials, property, documents or other information, or any 
reproduction or excerpt thereof, belonging to Employer or containing or 
pertaining to any Trade Secrets or Inventions.

           6.6   REMEDIES UPON BREACH In the event of any breach by Employee of 
the provision in this Section 6, Employer shall be entitled, if it so elects, to
institute and prosecute proceedings in any court of competent jurisdiction, 
either in law or in equity, to enjoin Employee from violating any of the terms 
of this Section 6, to enforce the specific performance by Employee of any of the
terms of this Section 6, and to obtain damages for any of them, but nothing 
herein contained shall be construed to prevent such remedy or combination of 
remedies as Employer may elect to invoke. The failure of Employer to promptly 
institute legal action upon any breach of this Section 6 shall not constitute a 
waiver of that or any other breach hereof.

     7.    COVENANT NOT TO COMPETE Employee agrees that, during Employee's 
employment, Employee will not directly or indirectly compete with Employer in
any way, and that Employee will not act as an officer, director, employee,
consultant, shareholder, lender or agent of any other entity which is engaged in
any business of the same nature as, or in competition with, the business in
which Employer is now engaged, or in which Employer becomes engaged during the
term of Employee's employment, or which is involved in science or technology
which is similar to Employer's science or technology.

     8.    GENERAL PROVISIONS

           8.1   ATTORNEYS' FEES In the event of any dispute or breach arising 
with respect to this Agreement, the party prevailing in any negotiations or 
proceedings for the resolution or enforcement thereof shall be entitled to 
recover from the losing party reasonable expenses, attorneys' fees and costs 
incurred therein.

           8.2   AMENDMENTS No amendment or modification of the terms or

parties hereto. There shall be no implied-in-fact contracts modifying the terms 
of this Agreement.

agreement between the parties with respect to the employment of Employee. This 
Agreement supersedes all prior agreements, understandings, negotiations and 
representation with respect to the employment relationship.

           8.4   SUCCESSORS AND ASSIGNS The Rights and obligations of Employer 
under this Agreement shall inure to the benefit of and shall be binding upon 
the successors and assigns of Employer. Employee shall not be entitled to assign
any of Employee's rights or obligations under this Agreement.

           8.5   WAIVER Either party's failure to enforce any provision of this 
Agreement shall not in any way be construed as a waiver of any such


 

Employment Agreement
Page 6

provision, or prevent that party thereafter from enforcing each and every other 
provision of this Agreement.

           8.6   SEVERABLE PROVISIONS The provisions of this Agreement are 
severable, and if any or more provisions may be determined to be judicially 
unenforceable, in whole or in part, the remaining provisions shall nevertheless

Employee (i) is free to enter into this Agreement and to perform each of the 
terms and covenants contained herein, (ii) is not restricted or prohibited,

(a) In the event that ----------------------------- the Company proposes to issue (a "Post-Determination Issuance") any New Voting --------------------------- Securities, and such issuance will occur at any time following the date when the conversion price for the Shares has been determined in accordance with the Restated Articles of Incorporation (the "Conversion Determination Date"), it ----------------------------- shall deliver written notice of such intention (the "Post-Determination Issuance --------------------------- Notice") to the Purchaser not less than 30 days prior to (i) the date of initial - ------ filing of a registration statement, in the case of a Public Offering or (ii) the expected date of issuance, in the case of any other Post-Determination Issuance. The Post-Determination Issuance Notice shall set forth in reasonable detail the terms of such Post- Determination Issuance, including, without limitation, (A) a description, and the number, of New Voting Securities proposed to be issued, (B) in the case of a Public Offering, the estimated price to the public, underwriting discount and commissions, expenses and underwriters of the Public Offering, (C) in the case of a Private Placement, the sales price, to the extent then known by the Company, and the identity of the proposed purchasers, and (D) in the case of a Non-Cash Transaction, a description of such transaction, including, without limitation, the consideration and the parties thereto. If information concerning the identity of proposed purchasers in a Private Placement becomes known to the Company subsequent to the delivery of the Post-Determination Issuance Notice, the Company shall, promptly after gaining such knowledge, deliver such information to the Purchaser in writing. (b) In connection with each Post-Determination Issuance, the Purchaser shall have the right (the "Post-Determination Preemptive Right") to ----------------------------------- purchase from the Company at the Applicable Preemptive Price simultaneously with, and otherwise upon the terms and subject to the conditions of, the Post- Determination Issuance up to the number of shares of Common Stock or other Voting Securities, as the case may be, necessary to permit the Purchaser to maintain the percentage of the outstanding Common Stock owned by the Purchaser and the percentage of Total Voting Power the Purchaser had, in each case, immediately prior to such Post-Determination Issuance (including, for purposes of calculating such percentage, all shares of Common Stock or other Voting Securities that the Purchaser has the right to acquire upon exercise of options or warrants, conversion or exchange of other securities or otherwise, if the Option has not yet been exercised, excluding the shares of Common Stock subject to the Option). (c) In the event that the Purchaser wishes to exercise its Post- Determination Preemptive Right, it shall deliver to the Company, not later than ten days prior to the proposed date of the initial filing of the registration statement, in the case of a Public Offering, and the proposed date of issuance, in any other case, a written notice (a "Post-Determination Subscription Notice") -------------------------------------- in which the Purchaser specifies the number of New Voting Securities which the Purchaser elects to purchase and in which the Purchaser agrees to purchase such specified number of New Voting Securities at the Applicable Preemptive Price subject to the same conditions as the Post-Determination Issuance. (d) In the event that the Company issues (such issuance being a "Pre- --- Determination Issuance") any New Voting Securities during the period beginning - ---------------------- on the date hereof and ending on and including the Conversion Determination Date, then the Purchaser shall have the option (the "Pre-Determination ----------------- Preemptive Rights) to purchase from the Company at the Applicable Preemptive - ----------------- Price for each such Pre-Determination Issuance up to the number of New Voting Securities issued in each such Pre-Determination Issuance equal to the Applicable Percentage. The "Applicable Percentage" means the greater of (i) the --------------------- percentage of outstanding Common Stock (including any other securities representing common equity) and (ii) the percentage of Total Voting Power, in either case that would have been held by the Purchaser if the Shares had been converted into shares of Common Stock immediately prior to such Pre-Determination Issuance at the conversion price of the Shares on the Conversion Determination Date (including, for purposes of calculating such percentage, all shares of Common Stock or other Voting Securities that the Purchaser has the right to acquire upon exercise of options or warrants, conversion or exchange of other securities or otherwise, but if the Option has not yet been exercised, excluding the shares of Common Stock subject to the Option). (e) In the event that the Purchaser wishes to exercise the Pre- Determination Preemptive Right, it shall deliver to the Company, at any time during the period commencing on the Conversion Determination Date and ending thirty days thereafter, a written notice in which the Purchaser specifies the number of New Voting Securities which the Purchaser elects to purchase and in which the Purchaser agrees to purchase such specified number of New Voting Securities at the Applicable Preemptive Prices. The closing of the purchase of New Voting Securities upon the Purchaser's exercise of the Pre-Determination Preemptive Right shall take place within five days of the receipt of the written notice referred to in the immediately preceding sentence. SECTION 5.05. Company Put Option. (a) The Company may, at its ------------------ option, require the Purchaser to purchase (the "Company Option") in accordance -------------- with the terms of this Section 5.05, Equity Securities in conjunction with either (i) the Initial Public Offering if the aggregate proceeds to the Company therefrom, net of underwriting discounts, commissions and other expenses, are not less than $17.5 million in cash (including the purchase price payable by the Purchaser pursuant to this Section 5.05) (a "Qualifying IPO") or (ii) any -------------- Private Placement of Equity Securities in which the proceeds to the Company, net of expenses, are not less than $10 million in cash (including the purchase price payable by the Purchaser pursuant to this Section 5.05) (a "Qualifying Private ------------------ Placement"). - --------- (b) In the event that the Company wishes to exercise the Company Option, it shall deliver written notice of such exercise (the "Put Notice") to ---------- the Purchaser not less than 30 days prior to (i) the closing date of a Qualifying Private Placement or (ii) the date of the filing with the Securities and Exchange Commission of a registration statement for the Qualifying IPO. Upon delivery of the Put Notice, the Purchaser shall be obligated to purchase from the Company, upon the same terms and subject to the same conditions as the underwriters in the case of a Qualifying IPO, and the other purchasers of Equity Securities in the case of a Qualifying Private Placement, the number of Equity Securities equal to not more than 25 percent of (x) the Equity Securities purchased by the underwriters (excluding Equity Securities purchased by such underwriters pursuant to any over-allotment option) in the case of a Qualifying IPO or (y) the Equity Securities purchased by other purchasers in the case of a Qualifying Private Placement. (c) Notwithstanding any other provision of this Section 5.05 to the contrary, (i) the Purchaser shall not be required to purchase Equity Securities having an aggregate purchase price of more than $5 million pursuant to the Company Option; (ii) the Purchaser shall not be required to purchase pursuant to the Company Option any Equity Securities being offered in conjunction with any securities other than Equity Securities; (iii) the Purchaser shall not be required to purchase Equity Securities if such purchase is prohibited by law, if any regulatory approval required to effect any purchase of Equity Securities upon exercise of the Company Option cannot be obtained or during any waiting period under the HSR Act or during any other period in which regulatory approvals are sought by the parties hereto pursuant to Section 5.10, but such purchase shall take place as promptly as practicable after any requisite waiting period has passed and any required notification period has expired or been terminated, or such approval has been obtained; and (iv) the Purchaser shall not be required to purchase Equity Securities pursuant to the Company Option if the Company (A) becomes insolvent, (B) a bankruptcy petition is filed with respect to the Company or any of its Subsidiaries, (C) is adjudicated as a bankrupt pursuant to an involuntary petition in bankruptcy, (D) suffers appointment of a temporary or permanent receiver, trustee or custodian for its business or for all or part of its assets, where such appointment is not discharged within thirty days, (E) makes an assignment for the benefit of creditors, (F) is admitted to the benefits of any procedure for the settlement or postponement of debts, (G) becomes a party to dissolution proceedings or (H) takes any corporate action with respect to any of the foregoing. (d) If the Company exercises the Company Option with respect to any Qualifying IPO or Qualifying Private Placement, the Purchaser shall have the right to purchase from the Company in connection with such Qualifying IPO or Qualifying Private Placement, in lieu of any rights granted to the Purchaser pursuant to Section 5.04, up to a number of Equity Securities equal to the greater of (i) forty percent of the Equity Securities sold in such Qualifying IPO or Qualifying Private Placement or (ii) the number of Equity Securities, if any, that the Purchaser would have had a right to acquire in accordance with Section 5.04, notwithstanding the Purchaser's right granted in this Section 5.05(d). (e) In the event that the Purchaser wishes to exercise the right granted in Section 5.05(d), it shall deliver to the Company, not later than ten days prior to (i) the proposed date of the initial filing of the registration statement, in the case of a Qualifying IPO, or (ii) the closing date, in the case of a Qualifying Private Placement, a written notice in which the Purchaser specifies the number of New Voting Securities which the Purchaser elects to purchase and in which the Purchaser agrees to purchase such specified number of New Voting Securities upon the same terms and subject to the same conditions as the underwriters in the case of a Qualifying IPO, and the other purchasers of Equity Securities in the case of a Qualifying Private Placement. Such right must be exercised by the Purchaser in accordance with the procedures set forth in Section 5.04. SECTION 5.06. Standstill Agreement. Until the earlier of (a) October -------------------- __, 1998 or (b) the Purchaser's exercise of the Option in accordance with Section 5.03, the Purchaser shall not, without the prior approval of the Board, acquire, agree to acquire, or make any proposal to acquire, directly or indirectly any securities of the Company, except for the acquisition of shares of Common Stock upon conversion of the Shares and in accordance with Article V of this Agreement. SECTION 5.07. Purchaser's Right of First Negotiation. If the Company -------------------------------------- receives any proposal concerning, or otherwise wishes to pursue, a merger, consolidation or other transaction in which all or a majority of the Company's equity securities or Voting Securities, all or substantially all of the Company's assets, or any material portion of the assets used by the Company in performing its obligations under the Distribution Agreement would be acquired outside of the ordinary course of business of the Company by any Person (a "Business Combination"), the Company shall deliver ---------------------- written notice (a "Business Combination Notice") of such proposal or intention --------------------------- to the Purchaser, in the case of a proposal, setting forth the terms of the proposal in reasonable detail. Upon receipt of a Business Combination Notice, the Purchaser shall have the exclusive right to negotiate with the Company concerning a Business Combination, which right shall expire (such period being the "Exclusivity Period") upon the earliest to occur of (a) the thirtieth day ------------------ following the commencement of the Exclusivity Period if the Purchaser shall have failed to commence good faith negotiations with the Company with respect to a Business Combination during such thirty day period, (b) either the Purchaser or the Company shall, following such thirty-day period, notify the other that it has reasonably determined that continued negotiations are unlikely to result in a Business Combination and (c) on the 120th day following the date of the Business Combination Notice if the Purchaser and the Company fail to enter into a definitive agreement to effect a Business Combination within such 120 day period. During the Exclusivity Period, the Company shall not engage in any discussions, negotiations, arrangements or understandings with, or provide any non-public or confidential information to, any Person other than the Purchaser with respect to a Business Combination. The Company and the Purchaser agree that all communications between the parties during the Exclusivity Period will be kept strictly confidential and the contents of those communications will not be disclosed to any other person except as, and to the extent, required by applicable law. For one year following the Exclusivity Period, the Company may only enter into a Business Combination with a Person other than the Purchaser if the terms of the Business Combination with such other Person, taken as a whole, are more favorable to the Company and its stockholders than the most favorable terms of a Business Combination proposed to the Company by the Purchaser during the Exclusivity Period. SECTION 5.08. Legend. The Purchaser agrees that all certificates ------ representing the Shares and the shares of Common Stock to be issued upon conversion of the Shares or pursuant to this Article V shall bear the following legend: "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR SECURITIES LAWS OF ANY STATE AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREUNDER." The Purchaser agrees to comply with the foregoing transfer restriction legend; and the Purchaser acknowledges that a transfer restriction will be maintained by the Company's stock transfer agent. The legend set forth in this Section 5.08 shall be removed by delivery of substitute certificate(s) without such legend if the Purchaser shall have delivered to the Company an opinion of counsel (it being agreed that Shearman & Sterling shall be deemed satisfactory) in form and substance reasonably satisfactory to the Company and its counsel, to the effect that such legend is not required for purposes of compliance with the Securities Act. SECTION 5.09. Board Observer; Board Representation. (a) During the ------------------------------------ period (such period being the "Observation Period") commencing on the ------------------ Purchaser's acquisition of any Equity Securities pursuant to Section 5.05 and ending on the earlier to occur of (i) the Purchaser's exercise of the Option and (ii) the Purchaser's sale of any of such Equity Securities acquired pursuant to Section 5.05, the Purchaser shall be entitled to have present at all meetings of the Board one Person designated by the Purchaser and reasonably acceptable to the Company (the "Purchaser Observer"). During the Observation Period, the ------------------ Company (i) shall deliver notice of all meetings of the Board to the Purchaser Observer simultaneously with, and in the same form as, notice to the directors of the Company and (ii) shall deliver to the Purchaser copies of all written materials furnished to the Board simultaneously with the delivery of such written materials to the Board. (b) From and after the Purchaser's exercise of the Option, (i) the Purchaser shall have the right to designate a percentage of directors of the Company (such persons being the "Purchaser Designees") equal to the percentage ------------------- of outstanding shares of Common Stock, on a fully diluted basis, owned by the Purchaser, rounded down to the next whole number, and (ii) at least one Purchaser Designee shall be a member of each Committee of the Board as long as the Purchaser owns at least 25% of the outstanding shares of Common Stock; provided, however, that if at any time following such exercise of the Option, - -------- ------- but only for so long as the Purchaser continues to own a majority of the outstanding shares of Common Stock, the Purchaser owns a majority of the outstanding shares of Common Stock, the Purchaser Designees shall constitute a majority of the directors of the Company and a majority of the members of each Committee of the Board. The Company agrees to take all action permitted by the MBCA necessary to cause the Purchaser Designees to become members of the Board. If the Board is divided into more than one class, the Purchaser Designees shall be distributed as equally as possible among such classes. (c) The Board shall recommend to the stockholders of the Company for election the Purchaser Designees who are nominated by the Company to serve as members of the Board, and the Company shall use its reasonable best efforts to solicit proxies from stockholders to vote in favor of such Purchaser Designees. In the event that a vacancy is created on the Board at any time by the death, disability, retirement, resignation or removal (with or without cause) of a Purchaser Designee, the Purchaser shall cause such Purchaser Designee to be elected to the Board to fill such vacancy. SECTION 5.10. Regulatory Approvals. If the Purchaser's acquisition -------------------- of any of the shares of Common Stock or Voting Securities subject to issuance pursuant to this Agreement (including, without limitation, the Common Stock or Voting Securities issuable upon conversion of the Preferred Stock or pursuant to Article V of this Agreement), requires approval of, or prior notification to, any regulatory authority pursuant to the HSR Act or otherwise, the Purchaser shall promptly file the required application for approval or notice and shall expeditiously process such notice or application, as the case may be, and the Company shall use all reasonable efforts to cooperate with the Purchaser in the filing of any such notice or application and the obtaining of any such approval. If the closing of the acquisition of shares of Common Stock or Voting Securities pursuant to this Article V cannot be consummated by reason of any applicable judgment, decree, order, law or regulation, such Closing shall take place as promptly as practicable after the date on which such restriction has expired or been terminated; without limiting the foregoing, if prior approval of, notification to or filing with, any regulatory authority is required pursuant to the HSR Act or otherwise, such closing shall take place as promptly as practicable after any requisite waiting period has passed and any required notification period has expired or been terminated, or such approval has been obtained. SECTION 5.11. Reservation of Shares. The Company shall at all times --------------------- reserve and keep available, free from preemptive rights (other than those of the Purchaser), out of its authorized and unissued Common Stock and Voting Securities the number of shares of Common Stock and Voting Securities subject to issuance upon conversion of the Shares (the "Reserve Amount"). The Company shall not take any corporate action which -------------- would require an adjustment in the number of shares of Common Stock and Voting Securities, unless either (i) immediately after such corporate action is taken and the transactions contemplated thereby are consummated, the number of authorized and unissued shares of Common Stock would equal or exceed the Reserve Amount, or (ii) concurrently with the taking of such corporate action, the Company shall take such corporate action as may be necessary to increase its authorized and unissued shares of Common Stock to such number as shall equal or exceed the Reserve Amount. The Company shall from time to time as necessary to fulfill the commitments made in this Article V authorize and make available, free from preemptive rights (other than those of the Purchaser), the number of shares of Common Stock and Voting Securities subject to issuance pursuant to this Article V. SECTION 5.12. Voting Rights; Rights Plan. (a) The Company shall not -------------------------- take any action to amend the By-Laws or Restated Articles of Incorporation so as to make Chapter 7B of the MBCA, or any successor thereto, applicable to any acquisition of shares of Common Stock or other Voting Securities by the Purchaser. In the event that the Restated Articles are amended so as to make Chapter 7B of the MBCA, or any successor thereto, applicable to any acquisition of shares of Common Stock or other Voting Securities by the Purchaser, the Company shall take such actions as shall be necessary and permitted by the MBCA so that (a) the shares of Common Stock or other Voting Securities that the Purchaser is entitled to acquire upon conversion of the Shares or pursuant to Article V hereof will, upon such issuance, and (b) the Shares will, in accordance with their terms, be duly accorded full voting rights. The Company shall use its best efforts, including the solicitation of votes by proxy, to obtain such votes of shareholders of the Company as shall be necessary to accord the Purchaser with such full voting rights. (b) The Company shall not adopt a shareholder rights plan, enter into any agreement, arrangement or understanding or grant any warrants, options, rights or any other privileges which, upon acquisition by the Purchaser of shares of Common Stock or other Voting Securities upon conversion of the Shares or pursuant to Article V hereof, would result in the Purchaser, in its capacity as a holder of such securities, being subject to different rights and obligations as all other holders of Common Stock or Voting Securities, as a result of such acquisition. SECTION 5.13. Survival of Representations and Warranties. The ------------------------------------------ representations and warranties of the Company in Article III and the Purchaser in Article IV shall survive the Closing until October , 1996. --- SECTION 5.14. Company's Right of First Negotiation. If the Purchaser ------------------------------------ elects to pursue a sale of all of the Company's Equity Securities and Voting Securities acquired pursuant to this Agreement ( a "Purchaser's Equity Sale"), ----------------------- the Purchaser shall deliver written notice (a "Purchaser's Equity Sale Notice") ------------------------------ of such intention to the Company. Upon receipt of a Purchaser's Equity Sale Notice, the Company shall have the exclusive right to negotiate with the Purchaser concerning a Purchaser's Equity Sale, which right shall expire upon the thirtieth day following the receipt of such notice. The Company and the Purchaser agree that all communications between the parties during such period will be kept strictly confidential and the contents of those communications will not be disclosed to any other person except as, and to the extent, required by applicable law. ARTICLE VI TERM, TERMINATION, AMENDMENT AND WAIVER --------------------------------------- SECTION 6.01. Term.

By: /s/ MATS WAHLSTROM ------------------------------ Name: Mats Wahlstrom Title: President AASTROM BIOSCIENCES, INC. By: /s/ R. DOUGLAS ARMSTRONG ------------------------------ Name: R. Douglas Armstrong Title: President and Chief Executive Officer AMENDMENT TO STOCK PURCHASE AGREEMENT This Amendment is entered into as of October 29, 1996 by and between Cobe Laboratories, Inc., a Colorado corporation (the "Purchaser") and Aastrom Biosciences, Inc., a Michigan corporation (the "Company") with respect to that certain Stock Purchase Agreement between the Purchaser and the Company, dated as of October 22, 1993 (the "Stock Purchase Agreement"). 1. Pursuant to Section 5.04 of the Stock Purchase Agreement, the Purchaser has certain preemptive rights to purchase additional capital stock of the Company. Pursuant to Section 5.05 of the Stock Purchase Agreement, the Company has a "put option" to require the Purchaser to purchase certain additional capital stock in the Company. 2. As specified in the definition set forth in the Stock Purchase Agreement, the "Applicable Preemptive Price" for the Purchaser to pay for purchasing the Company's capital stock in a public offering of stock by the Company is the public offering price, less underwriting discounts and commissions (e.g., a 7% underwriter's discount). 3. If the Company exercises its "put option" as specified in Section 5.05 of the Stock Purchase Agreement, the price per share payable by the Purchaser is the public offering price per share, less underwriting discounts and commissions (e.g., a 7% underwriter's discount). 4. The Purchaser and the Company hereby amend the Stock Purchase Agreement, and particularly the sections referenced above, so as to provide for the Purchaser to pay the same purchase price per share as is paid by a public purchaser in the public stock offering, if and when the Purchaser purchases capital stock of the Company pursuant to Section 5.04 and/or 5.05 pursuant to a public stock offering, without the Purchaser being entitled to a price discount for the underwriter's discounts or commissions. This foregoing amendment applies only to capital stock purchased by the Purchaser from the Company at the time of the Company's initial public offering of stock. 5. The Purchaser is agreeing to the foregoing modifications to the stock purchase price in consideration and recognition of the terms in that certain Stock Purchase Agreement (for Series F Preferred stock) between the Purchaser and the Company, and other good and valuable consideration, receipt of which is hereby acknowledged by the Purchaser. 6. Terms defined in the Stock Purchase Agreement shall have the same meaning in this Amendment. 7. Excepting only as otherwise set forth above, all other terms and provisions of the Stock Purchase Agreement shall remain in full force and effect. IN WITNESS WHEREOF, the Company and the Purchaser each have caused this Amendment to be executed by its duly authorized officer as of date first written above. COBE LABORATORIES, INC.

SECTION 2.04. Review of Program and ACL. (a) The Supplier and the ------------------------- Distributor contemplate that the Programs will be amended to address issues that cannot yet be addressed and also will be amended in response to unforeseen events, changes in circumstances and evolving market needs. Accordingly, the Supplier and the Distributor shall meet no more than four times per year to discuss amendments to each of the Programs. (b) Before the beginning of each Fiscal Year during the term of this Agreement, the Supplier and the Distributor shall mutually establish an annual commitment list (the "ACL"), which shall set forth: (i) the principal --- commitments and specific objectives that either the Supplier or the Distributor reasonably believes is important to achieve during the next Fiscal Year to accomplish the objectives set forth in Sections 2.03(a), (b) and (c) of this Agreement and to discharge the obligations of the Supplier and the Distributor under the Programs; (ii) those objectives or commitments of either the Supplier or the Distributor that require mutual agreement or coordination between the Distributor and the Supplier; and (iii) any change from the ACL of the preceding year, the Product Development Program or the Market Development Program, in either case that will materially affect either the timing of, or the mechanism for, the development of the Products for, or the delivery and/or marketing of the Products to, Stem Cell Therapy Customers. No provision of the ACL shall be changed, amended, or modified without the prior approval of the Supplier and the Distributor. Each of the Supplier and the Distributor shall use reasonable best efforts diligently to achieve each of the goals and objectives set forth on the ACL. If the Supplier and the Distributor are unable to reach mutual agreement on the inclusion of any commitment or objective on the ACL, then the Supplier and the Distributor will negotiate in good faith for 30 days in an attempt to resolve such disagreement. If the parties are unable to resolve such disagreement during such 30-day period, then either the Supplier or the Distributor may submit such disagreement to arbitration in accordance with Section 10.03. The Parties shall use their reasonable Page 16 best efforts to cause such arbitration to result in a decision within 40 days after submission thereto. (c) In connection with the preparation of the ACL and as otherwise reasonably required, the Market Development Program and the Product Development Program shall, at all times, include each of the Principal Components thereof set forth in Section 2.03 of this Agreement and such other items as are reasonably required to achieve the goals and objectives set forth in Sections 2.03(a), (b) and (c) of this Agreement. The Supplier and the Distributor shall give each other such information as is reasonably necessary to evaluate, and shall give due consideration to the views and recommendations of the other with respect to, all components of each of the Programs. The Product Development Program and the Market Development Program shall include sufficient details to enable the Distributor and the Supplier, respectively, to have a reasonable basis to assess the probability of achieving the goals and objectives set forth in the ACL and in Sections 2.03(a), (b) and (c) of this Agreement. Subject to the right of objection (and resolution of such objection) set forth below, the Supplier shall be free to amend the Product Development Program without the consent of the Distributor, and the Distributor shall be free to amend the Market Development Program without the consent of the Supplier. The Supplier may object to any amendment of, or failure to amend, any Principal Component of the Market Development Program, and the Distributor may object to any amendment of, or failure to amend, any Principal Component of the Product Development Program on the basis (i) that such amendment, or failure to amend, is not reasonably consistent with the goals and objectives set forth in the ACL or Sections 2.03(a), (b) and (c) of this Agreement, or (ii) that, as a result of such amendment, or failure to amend, the parties are not reasonably likely to achieve the goals and objectives embodied in such Principal Component. If the Supplier and the Distributor are unable to agree on a Principal Component of either Program the Supplier and the Distributor, each shall endeavor to resolve the disagreement within such 30-day period. If the Supplier and the Distributor are unable to resolve such disagreement within such 30-day period, either party shall be free to implement the Principal Component in question until such disagreement is resolved, unless the other party reasonably believes that the failure to resolve such disagreement will have an immediate adverse effect on the ability of the parties to implement the goals and objectives set forth in the ACL. In that case, either Party may cause the disagreement to be submitted immediately to arbitration in accordance with Section 10.03, and the Parties shall use their reasonable best efforts to cause such arbitration to be decided within 40 days after submission. If neither Party believes that there will be any such immediate adverse effect, then the Parties will continue to endeavor to resolve the disagreement for an additional period of six months. If the Parties are unable to resolve such disagreement within such six-month period, then the disagreement may be submitted to arbitration in accordance with Section 10.03. The Parties shall use their reasonable best efforts to cause such arbitration to result in a decision within a 40 day period. Page 17 (d) A copy of the ACL for the Fiscal Year ending June 30, 1994 is attached hereto as Schedule C. SECTION 2.05. Annual Customer Review; Change of Use. (a) The parties ------------------------------------- acknowledge that following the sale of any Product to any Customer, such Customer may subsequently (i) use such Product for applications other than those disclosed to the Supplier or the Distributor prior to such sale or (ii) change its use from Stem Cell Therapy Applications to other applications, or vice versa (a "Change of Use"). Notwithstanding anything in this Agreement to the ------------- contrary, the Distributor, or any Subdistributor, shall not be in breach of this Agreement if the Distributor (or such Subdistributor, as the case may be) acts in good faith and uses reasonable best efforts to ensure that it sells Products only to Stem Cell Therapy Customers, even though a Customer's predominant use of a Product may be for applications other than Stem Cell Therapy Applications. Similarly, notwithstanding anything in this Agreement to the contrary, the Supplier or any of its other distributors shall not be in breach of this Agreement if the Supplier (or such other distributor, as the case may be) acts in good faith and uses reasonable best efforts to ensure that it sells Products only to Persons other than Stem Cell Therapy Customers, even though a Person's predominant use of a Product may be for Stem Cell Therapy Applications. (b) The Supplier and the Distributor shall meet within three months after the end of each Fiscal Year during the term of this Agreement during which sales of the Products are made by either the Distributor, any Subdistributor or the Supplier or any of its other distributors to determine the extent to which the Distributor has sold Products to Customers other than Stem Cell Therapy Customers, the extent to which the Supplier has sold Products to Stem Cell Therapy Customers and the extent to which Customers of the Distributor or the Supplier have effected a Change of Use. At such meeting or meetings, the Distributor shall make available to the Supplier a survey of the Distributor's Customers whose purchases represent at least 80% of the Sales by the Distributor during such Fiscal Year (the "Distributor Customer Service Information"). The ---------------------------------------- Distributor Customer Service Information shall also provide a reasonable estimate of the expected predominant use of the Products by such Customers in the following Fiscal Year. The Supplier shall furnish the Distributor with comparable information regarding the Supplier's Sales of Products to Customers other than Stem Cell Therapy Customers (the "Supplier Customer Service ------------------------- Information"; and, together with the Distributor Customer Service Information, - ----------- the "Customer Service Information"). ---------------------------- (c) If it is determined: (i) that at the time of the Supplier's Sale of any Equipment to a Customer (other than an Affiliate of the Supplier), the Supplier knew or reasonably should have known that such Customer's intended predominant use of such Equipment was for Stem Cell Therapy Applications, the Page 18 Supplier shall pay to the Distributor an amount equal to 40% of all amounts received by the Supplier in payment for such Equipment; (ii) that a Customer of the Supplier (other than an Affiliate of the Supplier) uses any Disposable purchased from the Supplier for Stem Cell Therapy Applications, the Supplier shall pay to the Distributor an amount equal to 30% of all amounts received by the Supplier as payment for such Disposable; (iii) that at the time of the Distributor's (or any Subdistributor's) Sale of any Equipment to any Customer (other than an Affiliate), the Distributor (or such Subdistributor) knew or reasonably should have known that such Customer's intended predominant use of such Equipment was not for Stem Cell Therapy Applications, the Distributor (or such Subdistributor) shall pay to the Supplier all amounts received by the Distributor (or such Subdistributor) in payment for such Equipment; and (iv) that a Customer of the Distributor other than an Affiliate of the Distributor (or any subdistributor) has used any Disposable purchased from the Distributor (or such Subdistributor) for any application other than a Stem Cell Therapy Application, the Distributor (or such Subdistributor) shall pay to the Supplier an amount equal to 90% of all amounts received by the Distributor (or such Subdistributor) in payment for such Disposable. (d) The Supplier and the Distributor shall make available to each other such information as is reasonably necessary to audit the Sales of the other party described in 2.05(c) above. (e) If it is determined by the Supplier and the Distributor, based on the Customer Service Information or otherwise, (i) that a Customer of the Supplier has effected a Change of Use, such Customer may be redesignated, at the Supplier's option, as being a Stem Cell Therapy Customer and, accordingly, a Customer that the Distributor will have the responsibility to serve, or (ii) that a Customer of the Distributor has effected a Change of Use, such Customer may be redesignated, at the Distributor's option, as not being a Stem Cell Therapy Customer and, accordingly, a Customer that the Supplier will have the responsibility to serve. Upon any such redesignation, the Supplier and the Distributor shall develop a program that is reasonably acceptable to each party and such Customer for the orderly transition of responsibility for such Customer over a reasonable period of time not to exceed one year. Page 19 ARTICLE III SUPPLIER'S UNDERTAKINGS ----------------------- SECTION 3.01. Product Development Program; Diligence. The Supplier -------------------------------------- shall use reasonable best efforts to implement its obligations under the Product Development Program and the Market Development Program diligently.

To facilitate the Distributor's ability to be self- reliant in providing such training, the Supplier shall provide a license to the Distributor to use such technical information and know-how as the Supplier reasonably believes is necessary for such training. The Supplier shall not charge the Distributor for such training, but all costs incurred by personnel of the Distributor in the course of such training shall be the responsibility of the Distributor.

SECTION 3.05. Enforcement of Intellectual Property Rights. Promptly ------------------------------------------- upon receipt of notice of any infringement or threatened infringement ("Infringement") by third parties of the Supplier's Intellectual Property Rights - -------------- relating to the Sale of the Products to Stem Cell Therapy Customers ("SCTIP ----- Rights"), the Supplier shall, unless such notice was received pursuant to - ------ Section Page 20 4.05 hereof, promptly notify the Distributor of any such Infringement, and, as promptly as practicable thereafter, the Supplier and the Distributor shall jointly determine whether to take action to prevent such Infringement and otherwise to enforce the SCTIP Rights (all such actions being "IP Enforcement -------------- Actions"). In making such determination, the Supplier and the Distributor shall - ------- consider the impact that such Infringement is expected to have on Sales of the Products to Stem Cell Therapy Customers, the likelihood that such IP Enforcement Action will be successful, the expected cost of such IP Enforcement Action, the likelihood that such IP Enforcement Action will result in intellectual property claims against the Supplier or the Distributor ("Retaliatory IP Claims") and the --------------------- potential impact of any Retaliatory IP Claims on the Supplier and the Distributor. No IP Enforcement Action to enforce the SCTIP Rights will be undertaken without the consent of both the Supplier and the Distributor. If any such IP Enforcement Action is undertaken, the Supplier and the Distributor shall jointly retain a single counsel reasonably satisfactory to each of the Supplier and the Distributor, and all decisions relating to such IP Enforcement Action and the defense of any Retaliatory IP Claims shall be reasonably satisfactory to each of the Supplier and the Distributor. Sixty percent of all costs of prosecuting IP Enforcement Actions relating to SCTIP Rights and defending any Retaliatory IP Claims, including, without limitation, reasonable fees and disbursement of counsel, any reasonable out-of-pocket expenses incurred by the Supplier and the Distributor and any damages awarded against (or amount paid in settlement by) either the Supplier or the Distributor in any Retaliatory IP Claim (all such costs being "IP Enforcement Costs") shall be borne by the -------------------- Supplier and forty percent of such IP Enforcement Costs shall be borne by the Distributor, unless, and to the extent that, such IP Enforcement Action also benefits the Supplier's Sales of Products to Persons other than Stem Cell Therapy Customers, in which case the Distributor's share of such IP Enforcement Costs shall be reduced proportionally to reflect the benefit derived by each Party. All amounts received by the Supplier and the Distributor, whether as a result of damages awarded, settlement payments or otherwise, as a result of any IP Enforcement Action relating to SCTIP Rights, shall be shared by the Supplier and the Distributor in proportion to their respective share of the IP Enforcement Costs for such IP Enforcement Action. SECTION 3.06. Manufacturing and Labeling; Product Name; Parts.

The Supplier's obligation under this Section 3.06 to manufacture the Products shall include the affixing on the Products of labels agreed upon by the Supplier and the Distributor; provided, however, that any costs associated with the labeling of Products with the Distributor's name that would not be incurred but for such labeling will be at the Distributor's expense. The Products shall be labeled as a Product of both the Supplier and the Distributor, with the Distributor's name at least as prominent as the Supplier's name, unless otherwise required by law, in which case the Distributor's name shall be as prominent relative to the Supplier's name as shall be permitted by law. Page 21 (b) The Supplier shall have the right to name the Products and shall, in exercising such right, give due consideration to the views and recommendations of the Distributor. (c) The Supplier shall maintain a stock of Spare Parts for the Products in accordance with the Market Development Program. Spare Parts shall be priced in accordance with Section 5.02(e) of this Agreement. SECTION 3.07. Regulatory Approvals. (a) At its own expense, the -------------------- Supplier shall, in accordance with the Product Development Program, use reasonable best efforts diligently to obtain, in the name of the Supplier, all authorizations, consents, orders and approvals of all governmental authorities in the United States that may be or become necessary for the Distributor to sell the Products to Stem Cell Therapy Customers in the United States. (b) The Supplier shall provide to the Distributor such assistance, including, without limitation, providing at no charge all Products necessary for clinical trials and making any modifications to Products, as the Distributor may reasonably request to obtain the regulatory approvals necessary to sell the Products to Stem Cell Therapy Customers in countries other than the United States specified in the Market Development Program. SECTION 3.08. Intellectual Property Indemnification. The Supplier ------------------------------------- agrees to indemnify and hold harmless the Distributor and its Affiliates and all Subdistributors and their affiliates and their respective officers, directors, employees and agents (each such person being a "Supplier Indemnified Person") --------------------------- from and against any losses, claims, damages or liabilities and to reimburse each Indemnified Person for all expenses (including reasonable fees and expenses of counsel) as they are incurred, related to, arising out of or in connection with defending any action, claim, suit, investigation or proceeding (other than a Retaliatory IP Claim) in which a Person other than the Distributor claims or alleges that the sale of the Products by the Distributor to any Stem Cell Therapy Customer conflicts with or infringes on the Intellectual Property Rights of, or other intellectual property owned or licensed by, such Person.

The Policy shall be primary insurance with respect to -------- Product Liability Claims, and any insurance obtained by the Distributor shall be excess insurance. The Parties recognize that the nature of product liability claims and insurance available to cover product liability claims will change over the coming years and will vary from country to country. It is the agreement and goal of the Parties to obtain from time to time such liability insurance which protects both the Supplier and the Distributor to the maximum extent reasonably feasible, at prices which are commercially reasonable. To the extent reasonably feasible, both Parties shall endeavor to use the same counsel to defend both the Supplier and the Distributor in any Products Liability Claim. Both the Supplier and the Distributor shall, to the extent it does not increase its own risk of liability, cooperate with each other in the defense of any Product Liability Claim so as to minimize the risk of any liability to the other party. (b) The Supplier shall pay all Premiums and any losses, claims, damages or liabilities for Products Liability Claims to the extent not payable under the Policy (such losses, claims, damages, liabilities being "Unreimbursed ------------ Losses"), including, without limitation (including reasonable fees and expenses - ------ of counsel) any portion of any Unreimbursed Loss the Insurance Carrier is not obligated to pay because of any deductible, self-insured retention or similar provision of the Policy (a "Deductible").

SECTION 3.10. Forecasting Unit Demand. The Supplier and the ----------------------- Distributor shall agree upon a process of unit demand forecasting that meets the needs of the Supplier, the Distributor, and any sub-Suppliers to be used by the Supplier. A mechanism that the Supplier and the Distributor believe is workable is described in the Market Development Program, but both the Supplier and the Distributor recognize that this mechanism must be modified periodically as product and component lead times and delivery mechanisms are better understood by the Supplier and the Distributor.

Effective one year after delivering written notice to the other Party, either Party may terminate the Distributor's right to Sell in countries where a Co-Marketing Arrangement has been established.

The prices to be paid to the Distributor by the Supplier for the Products manufactured by the Distributor shall be fixed prices for each of the Products, based upon the amounts paid to the Supplier by the Distributor for each of the Products during the period preceding such termination, as negotiated in good faith by the Distributor and the Supplier. Such negotiated prices shall be applicable for one year, and shall be renegotiated and redetermined annually based upon the then current market conditions. Page 35 (b) Under the License, the Distributor shall pay to the Supplier on a monthly basis a royalty fee equal to 15% of the sales price to Customers (net of freight, delivery and returns) for Products sold during each month using such License, subject to reduction for any amounts payable by the Distributor to any third party pursuant to any agreement between the Supplier and such third party with respect to any Intellectual Property Rights granted to the Distributor under the License.

The arbitrator in such arbitration proceedings shall determine the prevailing Party, and the amount of attorneys' fees and other costs to be paid by the other Party to the prevailing Party. SECTION 7.09. Interest.

(b) If this Agreement is terminated the Distributor shall make available to the Supplier (i) a list of each Customer and Subdistributor which purchased Equipment from the Distributor, identifying the Equipment purchased by each such Customer and Subdistributor, (ii) a list of each Customer and Subdistributor which purchased Disposables during the 24 calendar months immediately preceding such termination, identifying the types and quantities of Disposables purchased by each such Customer and Subdistributor during the last 24 months, and (iii) a copy of each customer record of service performed within the last 24 calendar months for the Customers listed in subparagraphs (i) and (ii) above. Notwithstanding the foregoing, however, if the Supplier establishes a Co-Marketing Arrangement pursuant to Section 7.05(b) pursuant to which the Distributor is allowed to continue to distribute Products in one or more specific geographical areas, then the Distributor shall not Page 36 be required to furnish to the Supplier the foregoing lists and records for such geographical areas.

(a) The Distributor and the Supplier --------------- agree to keep secret and not to disclose to any third party any Confidential Information of the other that may from time to time be received from the other party in connection with the transactions contemplated by this Agreement; provided, however, that the Distributor may disclose such information to its Affiliates. The Confidential Information exchanged by the parties in connection with this Agreement shall not be used by the receiving party for any purpose other than for purposes of carrying out this Agreement during its term. The Supplier may disclose the Distributor's Confidential Information to the Supplier's employees and agents to the extent necessary to enable such employees and agents to perform the Supplier's responsibilities under this Agreement, and the Distributor may disclose the Supplier's Confidential Information to the Distributor's employees and agents and the Distributor's Subdistributors and their employees and agents to enable (i) such employees and agents to perform the Supplier's responsibilities under the Agreement and (ii) such Subdistributors to the extent necessary to assist the Distributor in the performance of its obligations under this Agreement. (b) The foregoing confidentiality obligations are subject to an exception for any disclosure that becomes legally required by subpoena or other legal process; provided, however, that the Party who so becomes legally obligated shall give written notice to the other Party of such required disclosure as promptly as practicable after the Party becomes aware of such disclosure requirements. SECTION 8.02. Survival of Covenants to Keep Secret. The parties' ------------------------------------ obligations under this Article VIII shall survive expiration or termination of this Agreement. SECTION 8.03. No License. Except as otherwise provided in this ---------- Agreement, nothing in this Agreement shall be construed to constitute a grant of any licensing rights from the Supplier to the Distributor to make the Products or to use the Products (other than a demonstration use for marketing to potential customers). Page 37 ARTICLE IX FORCE MAJEURE ------------- SECTION 9.01. Force Majeure. (a) If either party is rendered unable, ------------- in whole or in part, to carry out its obligations under this Agreement by reason of force majeure, and if such party gives prompt written notice to the other party describing the details giving rise to such party's claim of force majeure, then the party claiming force majeure shall be excused from performing its obligations hereunder, but only for so long as that party remains unable by reason of force majeure so to perform. Such cause of the party's inability to perform shall be remedied to the extent possible with all reasonable speed.

The lack of financial resources shall not constitute force majeure. (b) If any event of force majeure materially impairs the Distributor's ability to sell the Products or the Supplier's ability to manufacture the Product, then during the pendency of that force majeure event, the Supplier may sell the Products or the Distributor may manufacture the Products (as the case may be) that would otherwise have been sold by the Distributor or manufactured by the Supplier, but for the force majeure event.

Douglas Armstrong By:/s/ ------------------------- ------------------------ COBE BCT, INC. By:/s/ Edward C. Wood, Jr. ----------------------- 2 AMENDMENT to RESTATED DISTRIBUTION AGREEMENT between COBE BCT, INC. and AASTROM BIOSCIENCES, INC. This Amendment is made as of September 11, 1995, to that certain Restated Distribution Agreement dated as of October 22, 1993, between AASTROM Biosciences, Inc., a Michigan corporation (the "Supplier"), and Cobe BCT, Inc., a Colorado corporation (the "Distributor") (the "Restated Distribution Agreement"). 1. The terms which are defined in the Restated Distribution Agreement shall have the same meaning in this Amendment as defined in the Restated Distribution Agreement. 2. The definition of "Stem Cell Therapy Applications" in the Restated Distribution Agreement is hereby amended to add the words "or umbilical cord blood" on the second line, so that the first two and one-half lines read as follows: "Stem Cell Therapy Applications" means applications of the Products pursuant to which human bone marrow or peripheral blood or umbilical cord blood derived stem and hematopoietic cells are used primarily for one or more of the following:... 3. There shall be added to Section 1.01 of the Restated Distribution Agreement: new defined terms, as follows: "Lymphoid Cell" means lymphoid stem cell (e.g., any cell capable of generating cells solely of lymphoid lineage) and any cell derived therefrom, including but not limited to, the subcortical thymocyte, cortical thymocyte, medullary thymocyte, lymphocyte, B-cell, plasma cell, immunoblast, lymphoplasmacytoid cell and the NK-cell. "Lymphoid Cell Applications" means any expansion, selection or genetic manipulation, including genetic transformation, of Lymphoid Cells, provided that either the starting cell population is a lymphoid selected cell mixture, or that the mature lymphoid cell production is not derived ex vivo from a pre-lymphoid cell-type (e.g., multipotent stem cell). 1 4. The first sentence in Section 2.01(d) of the Restated Distribution Agreement is hereby amended to add the words "(excluding, however, for Lymphoid Cell Applications)" in two locations, so that the first sentence as amended reads as follows: (d) Notwithstanding any provision of this Agreement to the contrary, the Supplier may Sell the Products to its Affiliates for Stem Cell Therapy Applications by such Affiliates, but not for resale to Persons which are not Affiliates of the Supplier, and may make such Sales with a license for use of the Products for Stem Cell Therapy Applications, and the Distributor may Sell the Products to its Affiliates for applications other than Stem Cell Therapy Applications (excluding, however, Lymphoid Cell Applications) by such Affiliates, but not for resale to Persons which are not Affiliates of the Distributor, and may make such Sales with a license for use of the Products for applications other than Stem Cell Therapy Applications (excluding, however, for Lymphoid Cell Applications) (such permitted Sales by either the Distributor or the Supplier being "Affiliate Sales"). 5. Excepting only as otherwise set forth above, all other terms and provisions of the Restated Distribution Agreement shall remain in full force and effect. IN WITNESS WHEREOF, the Distributor and the Supplier each have caused this Amendment to be executed by its duly authorized officer as of the date first written above. COBE BCT, INC. By: /s/ EDWARD WOOD ----------------------------------------- Edward Wood, President AASTROM BIOSCIENCES, INC. By: /s/ R. DOUGLAS ARMSTRONG ----------------------------------------- R. Douglas Armstrong, Ph.D., President and Chief Executive Officer 2 AMENDMENT TO RESTATED DISTRIBUTION AGREEMENT This Amendment is made as of October 29, 1996 to that certain Restated Distribution Agreement dated as of October 22, 1993, between Aastrom Biosciences, Inc., a Michigan corporation (the "Supplier") and Cobe BCT, a Colorado corporation (the "Distributor") (the "Restated Distribution Agreement"). 1. With respect to the Purchase Price payable by the Distributor to the Supplier for the Product as specified in Article V of the Restated Distribution Agreement, the parties hereby agree that the Distributor shall be entitled to a 5% discount on the Purchase Price for all of the Product purchased until the aggregate of said discount equals a total of $350,000, increased by 25% per annum, compounded annually, from December 15, 1996, until the date the first $200,000 in aggregate discounts are actually realized and credited. Said aggregate discount, including the compounded increase, shall hereinafter be called the "Aggregate Discount". If the Aggregate Discount has not been realized by the second anniversary of the first commercial sale of the Product by the Distributor, then the discount on subsequent sales of the Product from the Supplier to the Distributor shall be at 10% (rather than 5%), until the Aggregate Discount is realized by the Distributor. 2. An example of the calculations for the Aggregate Discount specified in Section 1 above is as follows: a. First Product sold to Distributor (12/15/97) b. First $200,000 discount credit at 5% actually realized by Distributor (12/15/98) c. Aggregate Discount ($350,000 x 1.25/2/) as of 12/15/98: 546,875 d. Less $200,000 discount credit at 5% actually realized as of 12/15/98: (200,000) --------- e. Net balance of Aggregate Discount as of 12/15/98: 346,875 f. Further $300,000 discount credit at 5% actually realized from 12/16/98 to 12/15/99: (300,000) --------- g. Net balance of Aggregate Discount as of 12/15/99: 46,875 h. Further $46,875 discount credit at 10% actually realized after 12/15/99: (46,875) --------- i. Aggregate Discount is fully realized. 3. The Supplier has agreed to the foregoing discount in consideration and recognition of the assistance which the Distributor has given to the Supplier in the development of the Product. 4. Terms defined in the Restated Distribution Agreement shall have the same meaning in this Amendment. 5. Excepting only as otherwise expressly set forth above, all other terms and provisions of the Restated Distribution Agreement shall remain in full force and effect. IN WITNESS WHEREOF, the Distributor and the Supplier each have caused this Amendment to be executed by its duly authorized officer as of the date first written above. COBE BCT, INC. By: /s/ Edward C.

                 ----------------                                        
exclusive, worldwide license to use, make, have made and sell all products
and/or processes utilizing the Licensed Technology, with the full right to grant
sublicenses, subject to the terms of this Agreement.

             2.2 Reimbursement of Patent Costs.  As a part of the consideration
                 -----------------------------                   
for the exclusive license granted pursuant to Section 2.1 hereof, Licensee shall
reimburse Licensor for Licensor's out-of-pocket costs incurred for patent
attorney fees and patent application filing fees in connection with the Licensed
Patents, up to an aggregate maximum of $25,000. Such reimbursement shall be
subject to Licensor's presentation of appropriate documentation of Licensor's
payment of such expenses.

                                      -3-

 
No payment shall be payable by Licensee hereunder unless and until the issue of
the validity of the claims as now stated in the Licensed Patents as described in
Section 3.1 hereof is resolved favorably to Licensor's reasonable satisfaction,
or, upon the expiration of one (1) year after the date of this Agreement if no
request for re-examination of the Licensed Patents is made within such period.
All payments made by Licensee to Licensor pursuant to this Section 2.2 shall be
credited against Licensee's obligation to pay royalties as set forth in Section
2.3 hereof.

             2.3  Royalties.
                  --------- 

                  2.3.1  Percentage Royalty.  As additional consideration for
                         ------------------
the exclusive license granted pursuant to Section 2.1 hereof, Licensee shall pay
to Licensor a continuing royalty on a country-by-country basis in the amount of
(i) three percent (3%) of Net Sales of Licensed Products made, used or sold in
any country where the Licensed Technology utilized therein is protected by a
valid patent.

                  2.3.2  Credits Against Royalties.  Licensee shall be entitled
                         -------------------------
to a credit against royalties payable hereunder in an amount equal to the
payments made by Licensee under Sections 2.2 and 3.4 hereof.

                  2.3.3  Minimum Annual Royalty.  From and after January 1,
                         ----------------------
1997, Licensee shall pay to Licensor minimum annual royalties as set forth
herein. The minimum annual royalty for the calendar year 1997 shall be $20,000.
For the three years thereafter, the minimum annual royalty for each subsequent
calendar year shall increase by $10,000, such that for all years after and
including the calendar year 2000, the minimum annual royalty shall be $50,000.
Any percentage royalties accrued and paid to Licensor (but not taken as a credit
pursuant to Section 2.3.2 hereof) for any calendar year shall be credited
against the minimum royalty payable for such calendar year. The payment of any
shortfall between actual royalties paid and the minimum annual royalty
applicable to such calendar year shall be payable to Licensor within sixty (60)
days after the last day of such calendar year. Licensor's sole remedy for any
failure by Licensee to pay the minimum annual royalty required hereunder shall
be to convert the exclusive license granted hereunder to a nonexclusive license
upon the expiration of sixty (60) days' written notice of Licensor's intention
to so convert the license, without Licensee's payment of any delinquent minimum
annual royalty. Such conversion would not relieve Licensee from payment of
royalties as described in Section 2.3.1.

exclusive and if Licensor grants a license to use the Licensed Patents to any
third party at a royalty rate lower than three percent (3%), then the royalty
rate payable by

                                      -4-

 
Licensee under this Agreement shall be reduced to the same rate payable by the
third party.

                 2.4  Combination Product.
                      ------------------- 

                      2.4.1  Definition of Combination Product.  As used herein,
the term "Combination Product" shall mean a Licensed Product which cannot be
manufactured, used or sold without (i) infringing the Licensed Patents, and also
(ii) infringing one or more patents held by Licensee or a third party (referred
to herein as "other patent rights").
  
                      2.4.2  Net Sales of Combination Product. The Net Sales 
                             --------------------------------
of a Combination Product shall be determined in accordance with the following
formula:

                                A
                            X = - x C
                                B         , where

                            X = the Net Sales attributable to the portion of the
                      Combination Product which is attributable to the Licensed
                      Patents, on which Net Sales Licensee shall pay the royalty
                      rate set forth in Section 2.3.1; and

                            A = the value of the contribution of the Licensed
                      Patents (as compared to the value of the contributions of
                      the rights) used in the Combination Product; and

                            B = The aggregate value of all patent rights used
                      for the Combination Product, consisting of both the
                      Licensed Patents and all other patent rights used in the
                      Combination Product; and

                            C = the Net Sales for the Combination Product.

The values described above shall be determined by the parties hereto in good
faith.  In the absence of agreement as to said values, the values shall be
determined by arbitration in accordance with the provisions of Section 10.2
hereof.

                 2.5  Component Product.
                      ----------------- 

                      2.5.1  Definition of Component Product.  As used herein,
                             -------------------------------
the term "Component Product" shall mean a Licensed Product which is a distinct
component of a product which contains multiple components (including, as an
example of additional components, proprietary methods sold or licensed with the
Component Product).

                                      -5-

 
                      2.5.2  Net Sales of Component Product.  The Net Sales of a
                             ------------------------------
Component Product shall be determined in accordance with the following formula:

                               A
                           X = - x C
                               B         , where

                           X = the Net Sales attributable to the Component
                      Product, on which Licensee is obligated to pay the royalty
                      rate set forth in Section 2.3.1; and

                           A = the value of the Component Product, based upon
                      costs to manufacture the Component Product, or the sales
                      price of the Component Product if it is sold separately;
                      and

                           B = The value of the aggregate product, with all
                      components (including methods sold or licensed with the
                      Component Product), including the Component Product, based
                      upon the same criteria as used for A above; and

                           C = the Net Sales for the aggregate product.

The values described above shall be determined by the parties in good faith.  In
the absence of agreement as to said values, the values shall be determined by
arbitration in accordance with the provisions of Section 10.2 hereof.

                 2.6  Quarterly Payments.
                      ------------------ 

                      2.6.1  Sales by Licensee.  With regard to Net Sales made
                             -----------------
by Licensee or its Affiliates, royalties shall be payable by Licensee quarterly,
within ninety (90) days after the end of each calendar quarter, based upon Net
Sales of Licensed Products during such preceding calendar quarter, commencing
with the calendar quarter in which the first commercial sale of any Licensed
Product is made.

                      2.6.2  Sales by Sublicensees.  With regard to Net Sales
                             ---------------------
made by sublicensees of Licensee or its Affiliates, royalties shall be payable
by Licensee quarterly, within one hundred twenty (120) days after the end of
each calendar quarter, based upon the Net Sales of Licensed Products by such
sublicensee during such preceding calendar quarter, commencing with the calendar
quarter in which the first commercial sale of any Licensed Product is made by
such sublicensee.

                 2.7  Term.  The term of this Agreement and the license granted
                      ----                                                     
hereunder shall commence on the date set forth in the preamble paragraph of this
Agreement, and unless sooner

                                      -6-

 
terminated by Licensee upon delivery of thirty (30) days' written notice or in
accordance with the provisions of Section 8.1 hereof, the term of this Agreement
and the license granted hereunder shall expire when the last patent licensed
hereunder has expired.

                 2.8  Sublicense Rights.  Licensee shall have the sole and
                      -----------------
exclusive right to grant sublicenses to any party with respect to the rights
conferred upon Licensee under this Agreement, provided, however, that any such
sublicense shall be subject in all respects to all of the provisions contained
in this Agreement (but not including the payment of patent costs pursuant to
Sections 2.2 and 3.4 hereof and the obligation to pay minimum annual royalties
pursuant to Section 2.3.3 hereof). Licensee shall pay Licensor, or cause its
Affiliates or sublicensees to pay Licensor, the same royalties on all Net Sales
of such Affiliate or sublicensee the same as if such Net Sales had been made by
Licensee. Each Affiliate and sublicensee shall report its Net Sales to Licensor
through Licensee, which Net Sales shall be aggregated with any Net Sales of
Licensee for purposes of determining the Net Sales upon which royalties are to
be paid to Licensor. Any royalties paid to Licensor with respect to Net Sales of
any Affiliate or any sublicensee of Licensee or any Affiliate shall be credited
against Licensee's minimum annual royalty obligations hereunder.

                 2.9  Duration of Royalty Obligations.  The royalty obligations
                      -------------------------------
of Licensee as to each Licensed Product shall terminate on a country-by-country
basis concurrently with the expiration of the last to expire of the patents
licensed hereunder utilized by or in such Licensed Product in each such country.
Notwithstanding any other provision of this Agreement, in the event that, based
upon a challenge by a party other than Licensee, its Affiliates or sublicensees,
the existing favorable claims of the Licensed Patents are held to be invalid by
the PTO or any competent court of law, Licensee may terminate this Agreement and
Licensee thereafter shall have no further obligation to pay any royalties
hereunder.

                 2.10  Reports.  Licensee shall furnish to Licensor at the same
                       -------
time as each royalty payment is made by Licensee, a written report of Net Sales
of Licensed Products and the royalty due and payable thereon, including a
description of any offsets or credits deducted therefrom, on a product-by-
product and country-by-country basis, for the calendar quarter upon which such
royalty payment is based.

                 2.11  Records.  Licensee shall keep, and cause its Affiliates
                       -------
and sublicensees to keep, complete records and accounts of all sales of Licensed
Products in sufficient detail to enable the royalties payable on Net Sales of
each Licensed Product to be determined. Licensor shall have the right to appoint
an independent certified public accounting firm approved by Licensee, which
approval shall not be unreasonably withheld,

                                      -7-

 
to audit, upon delivery of advance written notice and during normal business
hours without interruption of normal business operations, the records of
Licensee, its Affiliates and sublicensees as necessary to verify the royalties
payable pursuant to this Agreement. Licensee, its Affiliates and sublicensees
shall pay to Licensor an amount equal to any additional royalties to which
Licensor is entitled as disclosed by the audit. Such audit shall be at
Licensor's expense. Licensor may exercise its right of audit hereunder no more
frequently than once in any calendar year. The accounting firm shall disclose to
Licensor only such information as is necessary to verify the accuracy of the
royalty payments required hereunder, and all such information shall be treated
as Confidential Information by Licensor. Licensee, its Affiliates and
sublicensees shall preserve and maintain all records required for audit for a
period of three (3) years after the calendar quarter to which the record
applies.

                 2.12  Foreign Taxes.  Any tax required to be withheld by
                       -------------
Licensee under the laws of any foreign country for the account of Licensor shall
be paid by Licensee for and on behalf of Licensor to the appropriate
governmental authority and deducted from any royalties payable by Licensee
hereunder.

             3.  Patent Matters.
                 -------------- 

                 3.1  Validity of Licensed Patents.  The parties hereto
                      ----------------------------
acknowledge that there may be an issue concerning the validity of some of the
claims of the existing Licensed Patents. In order to resolve such issue,
Licensee may, in the exercise of its sole discretion and at its sole expense,
request a re-examination of the existing Licensed Patents by the PTO and the
applicable foreign agencies. Each of the parties hereto shall exercise good
faith and due diligence in their efforts to establish the validity of the
existing Licensed Patents.

                 3.2  Patent Prosecution and Maintenance.  From and after the
                      ----------------------------------
date of this Agreement, the provisions of this Section 3.2 shall control the
prosecution and maintenance of the Licensed Patents. Licensee shall direct and
control (i) the maintenance of Patent '292 and the re-examination of Patent '292
described in Section 3.1 hereof; (ii) the preparation, filing and prosecution of
all other domestic and foreign patent applications relating to Licensed
Technology (including any interferences and foreign oppositions); and (iii) the
maintenance of any patents issuing therefrom. Licensee shall select the patent
attorney, and the fees and expenses incurred by Licensee with respect to
services performed by such patent counsel and any filing or other fees shall be
paid as set forth below in Section 3.4. Licensor shall assist Licensee and
patent counsel retained by Licensee as necessary to accomplish the patent
processes described hereunder. Licensor shall sign all documents which are
reasonably necessary to enable Licensee to prosecute and maintain all patent
matters. Licensee shall use good faith and due diligence in determining

                                      -8-

 
which foreign countries, in addition to the U.S.A., in which to file for and
maintain patent rights, depending on the commercial benefits Licensee can
reasonably anticipate in each country.  In as much as Licensee is paying the
patent costs, the ultimate decision as to all of these patent prosecution and
maintenance matters shall be made by Licensee.

                 3.3  Information to Licensor.  Licensee shall keep Licensor
                      -----------------------
informed with regard to the patent application, re-examination and maintenance
processes. Licensee shall deliver to Licensor copies of all patent applications,
amendments, related correspondence, and other related  matters.

                 3.4  Patent Costs.  The parties hereto agree that the exclusive
                      ------------                                              
license granted hereunder is in part in consideration for Licensee's assumption
of patent costs and expenses as described herein.  Licensee shall pay for all
expenses incurred by Licensee pursuant to Sections 3.1 and 3.2 hereof, in
addition to patent costs paid by Licensee as set forth in Section 2.2 hereof.

                 3.5  Ownership.  Patent '292 and the patent applications filed
                      ---------
and the patents obtained by Licensee pursuant to Section 3.2 hereof shall be
owned solely by Licensor, and included in the exclusive license granted
hereunder.

                 3.6  Infringement Actions.
                      -------------------- 

                      3.6.1  Prosecution and Defense of Infringements.  Licensee
                             ---------------------------------------- 
shall have the right but not the obligation to prosecute any and all
infringements of any patent licensed hereunder and to defend all charges of
infringement arising as a result of the exercise by Licensee, its Affiliates or
sublicensees of the rights granted hereunder. Licensee may enter into
settlements, stipulated judgments or other arrangements respecting such
infringement, at its own expense. Licensor shall permit any action to be brought
in his name if required by law, and Licensee shall hold Licensor harmless from
any costs, expenses of liability respecting all such infringements or charges of
infringement, except such infringements as shall result from any breach of
warranty made by Licensor herein. Licensor agrees to provide all necessary
assistance of a technical nature which Licensee may require in any litigation
arising with respect to the Licensed Technology. In the event Licensee elects
not to prosecute any infringement, Licensee shall notify Licensor in writing
promptly and Licensor shall have the right to prosecute such infringement on his
own behalf. If Licensee elects to prosecute an infringement, then Licensor shall
not be entitled to do so.

                      3.6.2  Allocation of Recovery.  Any damages or other
                             ----------------------
recovery from an infringement action undertaken by Licensee pursuant to Section
3.6.1 shall be retained by Licensee as its exclusive property; but any such
recovery, net of

                                      -9-
 
Licensee's costs of litigation, shall be treated as "Net Sales" and Licensee
shall pay a royalty thereon pursuant to Section 2.3.1 above.  If Licensee elects
to not prosecute an infringement, and Licensor does prosecute said infringement,
then Licensee shall retain any recovery received from said prosecution.

             4.  Obligations Related to Commercialization.
                 ---------------------------------------- 

                 4.1  Commercial Development Obligation.  In order to
                      ---------------------------------
maintain Licensee's exclusive license rights granted hereunder in force,
Licensee shall use reasonable efforts and due diligence to develop the Licensed
Technology into commercially viable Licensed Products, as promptly as is
reasonably and commercially feasible, and thereafter to produce and sell
reasonable quantities of Licensed Products. Licensee shall keep Licensor
generally informed as to Licensee's progress in such development, production and
sale, including its efforts, if any, to sublicense Licensed Technology.

                 4.2   Milestone.  If Licensee has not, by July 1, 1998,
                       ---------
pursued reasonable efforts and due diligence to develop the Licensed Technology
into commercially viable Licensed Products, such that there is a reasonable
probability of Net Sales forthcoming, then Licensor may require Licensee to pay
to Licensor a one-time payment of Fifty Thousand Dollars ($50,000) as a
condition to retaining the exclusivity of the license granted hereunder in
force.  If said payment is so required and not paid, then Licensee's rights
under this Agreement shall become non-exclusive and no minimum royalties shall
thereafter be payable.  If Licensor concludes that Licensee has failed to pursue
said reasonable efforts and due diligence, then Licensor shall give written
notice of said conclusion to Licensee, and Licensee shall have three months
after receipt of said notice to cure the failure.  If there is a dispute as to
whether there is a failure or a cure, the dispute shall be resolved by
arbitration pursuant to Section 10.2 below.

                 4.3  Governmental Approvals and Marketing of Licensed
                      ------------------------------------------------
Products. Licensee shall be responsible for obtaining all necessary governmental
- --------
approvals for the development, production, distribution, sale and use of any
Licensed Product, at Licensee's expense. Licensee shall have sole responsibility
for any warning labels, packaging and instructions as to the use of Licensed
Products and for the quality control for any Licensed Product.

                 4.4  Product Liability Indemnity.  Licensee hereby agrees
                      ---------------------------
to indemnify, defend and hold harmless Licensor from and against any liability
or expense arising from any product liability claim asserted by any party as to
any Licensed Product made or sold by Licensee or its Affiliates and
sublicensees, other than any claim which arises due to a breach by Licensor of
any warranty made herein.

                                     -10-

 
             5.  Representations and Warranties.  Licensor hereby represents and
                 ------------------------------                                 
warrants that (i) he is the rightful owner of the Licensed Technology, (ii) the
Licensed Technology is not subject to any lien, license, assignment, security
interest or other encumbrances, (iii) he has made full disclosure to Licensee of
all communications with respect to the Licensed Technology with the PTO and any
foreign patent agencies, (iv) he has the power and authority to enter into this
Agreement and grant the license provided for hereunder, and (v) except as
disclosed to Licensee, Licensor has no knowledge that the Licensed Technology
infringes any patents or other intellectual property rights of third parties, or
that any third party is in any way infringing the Licensed Technology covered by
this Agreement.

             6.  Interests in Intellectual Property Rights.
                 ----------------------------------------- 

                 6.1  Preservation of Title.  Licensor shall retain full
                      ---------------------
ownership and title to Licensed Technology, Patent '292 and any other patents
licensed hereunder and shall use his reasonable best efforts to preserve and
maintain such full ownership and title.

                 6.2  Ownership of Improvements.
                      ------------------------- 

                      6.2.1  Developed by Licensee.  Any improvements to
                             --------------------- 
Licensed Technology conceived, developed or reduced to practice by Licensee, its
Affiliates or sublicensees or their employees shall remain the sole and
exclusive property of such party, and shall not be included in Licensed
Technology hereunder.

                      6.2.2  Developed by Licensor.  Any improvements to
                             ---------------------
Licensed Technology conceived, developed or reduced to practice by Licensor
during the term of this Agreement shall be included in Licensed Technology and
subject to the exclusive license granted hereunder.

             7.  Confidentiality and Publication.
                 ------------------------------- 

                 7.1  Treatment of Confidential Information.  The parties agree
                      -------------------------------------
that during the term of this Agreement, and for a period of three (3) years
after this Agreement terminates, a party receiving Confidential Information of
the other party will (i) maintain in confidence such Confidential Information to
the same extent such party maintains its own proprietary industrial information,
(ii) not disclose such Confidential Information to any third party without prior
written consent of the other party and (iii) not use such Confidential
Information for any purpose except those permitted by this Agreement.

                 7.2  Publications.  In order to protect the rights granted to
                      ------------
Licensee hereunder, Licensor shall submit to Licensee copies of proposed
publications of Licensor which contain subject matter relating to intellectual
property licensed hereunder and

                                     -11-

 
afford Licensee sixty (60) days to review such proposed publications.  Upon
timely written request by Licensee, Licensor shall delay any such publication to
facilitate the preparation and filing of a patent application, which delay shall
not exceed ninety (90) days from the date Licensee requests such delay.

             8.  Termination.
                 ----------- 

                 8.1  Termination Upon Default.  Upon the failure of a party to
                      ------------------------
perform any obligation required of it or him to be performed hereunder, and the
failure to cure within thirty (30) days after receipt of written notice from the
other party specifying in reasonable detail the nature of such default, the non-
defaulting party may deliver to the defaulting party written notice of intent to
terminate, such termination to be effective upon the date set forth in such
notice.

             Such termination rights shall be in addition to and not in
substitution for any other remedies that may be available to the non-defaulting
party. Termination pursuant to this Section 8.1 shall not relieve the defaulting
party from liability and damages to the other party for breach of this
Agreement. Waiver by either party of a single default or a succession of
defaults shall not deprive such party of any right to terminate this Agreement
arising by reason of any subsequent default.

                 8.2  Transfer Upon Bankruptcy or Insolvency.  In the event of
                      -------------------------------------- 
the bankruptcy or insolvency of Licensee, this Agreement and the rights granted
to Licensee hereunder may be transferred by Licensee or any trustee appointed
for the estate of Licensee, provided such transferee shall agree in writing to
comply with all of the terms and conditions set forth herein and to cure any
financial defaults by Licensee.

                 8.3  Rights Upon Expiration.  Neither party shall have any
                      ----------------------
further rights or obligations upon the expiration of this Agreement other than
the obligation of Licensee to make any and all reports and payments for the
final quarter period. Provided, however, that upon such expiration, each party
shall be required to continue to abide by its non-disclosure obligations as
described in Section 7.1, and Licensee shall continue to abide by its obligation
to indemnify Licensor as described in Section 4.4 for products sold prior to the
termination.

                 8.4  Rights Upon Termination.  Notwithstanding any other
                      -----------------------
provision of this Agreement, upon any termination of this Agreement prior to the
regularly scheduled expiration date of this Agreement, the license granted
hereunder shall terminate. Except as otherwise provided in Section 8.5 of this
Agreement with respect to work-in-progress, upon such termination, Licensee
shall have no further right to develop, manufacture or sell any Licensed
Products, or to otherwise use any Licensed Technology. Any such termination
shall not relieve either party from any obligations accrued to the date of such
termination. Upon such

                                     -12-

 
termination, each party shall be required to abide by its nondisclosure
obligations as described in Section 7.1, and, provided termination was not
initiated by Licensee due to Licensor's breach hereunder, Licensee shall
continue to abide by its obligations to indemnify Licensor as described in

EXHIBITS A General Description of the System and the Instrument B Specifications and Functional Requirements for the Instrument C Time and Quantity Schedule - Preproduction Units C1 Pricing for Precommercial Units D Manufacturing Drawings for the Instrument E Compensation Schedule for Design Work and Manufacturing Preproduction Units F Summary of Manufacturing Agreement for Phase II -ii- COLLABORATIVE PRODUCT DEVELOPMENT AGREEMENT (Instrument) This Collaborative Product Development Agreement (the "Agreement") is entered into as of May 10, 1994, by and between Aastrom Biosciences, Inc., a ------ Michigan corporation ("Aastrom"), and SeaMED Corporation, a Delaware corporation ("SeaMED"). A. Aastrom is in the final stages of research and development for a proprietary Cell Expansion System which is used for stem cell growth (the "System"). The System includes an instrument or instruments (the "Instrument") and a disposable biochamber cartridge. Aastrom has completed a working prototype model of the System; and Aastrom now needs to complete the design of the Instrument and to obtain (i) pre-production models defined as pre-revision Rev. A specification units (hereinafter called "preproduction units") of the Instrument for laboratory and clinical evaluation, and (ii) pre-commercial models, defined as units made once the release occurs for Rev. A specification units (hereinafter called "precommercial units") of the Instrument for laboratory and clinical evaluation. Attached hereto as Exhibit A is a general description of the System, including the Instrument. B. SeaMED has expertise and experience in the development and manufacture of medical instruments which are somewhat similar to the Instrument, and SeaMED is prepared to collaborate with Aastrom for completing the necessary design work on the Instrument to enable SeaMED to produce preproduction units and precommercial units of the Instrument for laboratory and clinical evaluation as outlined in the SeaMED Project Plan, Drawing Number 908180, draft dated 2-2-94. C. As further described in this Agreement, (i) the design and manufacture of preproduction units and precommercial units of the Instrument shall be referred to as Phase I, and (ii) the subsequent manufacture of commercial units (defined as any unit that is sold) of the Instrument shall be referred to as Phase II. D. Pursuant to the terms of this Agreement, during Phase I SeaMED shall (i) collaborate with and assist Aastrom to design the preproduction units and precommercial units of the Instrument, and (ii) manufacture the preproduction units and precommercial units of the Instrument. At least six months prior to the expected commencement of Phase II, Aastrom and SeaMED shall pursue good faith negotiations for entering into a Manufacturing Agreement for SeaMED to manufacture the commercial units of the Instrument, as further described in 1 Section 6 of this Agreement. Because of foreign governmental approval requirements, it is possible that there still will be some preproduction units and precommercial units being made during Phase I, while at the same time there will be some commercial units being made during Phase II. E. Aastrom has contracted with Roecker Design Group, and Aastrom may also contract with other design specialists for assistance with specified aspects of the System and/or Instrument (collectively called the "Other Design Contractors"). AGREEMENT NOW, THEREFORE, the parties hereby agree as follows: 1. Responsibilities of Aastrom. --------------------------- 1.1 Project Management. Aastrom shall be responsible for overall ------------------ project management relating to the development of the Instrument. 1.2 Specifications. Aastrom shall collaborate with SeaMED and the -------------- Other Design Contractors on completing the design work for the Instrument. With assistance from SeaMED as more fully described in Section 2 below, Aastrom shall develop the final specifications and functional requirements for the preproduction units and precommercial units (including applicable test criteria) (the "Specifications"). Upon completion of the Specifications, Aastrom shall promptly provide SeaMED with a copy of the Specifications, and the Specifications shall be incorporated herein as Exhibit B hereto. 2. Responsibilities of SeaMED. -------------------------- 2.1 Design Collaboration. SeaMED shall collaborate with Aastrom -------------------- and the Other Design Contractors on completing the design work for the Instrument.

The system is intended to provide cells in sufficient volume and with the necessary characteristics to complete a bone marrow transplantation or a nadir prevention/rescue resulting from therapies such as high dose chemotherapy or radiation. These cells are grown from a small starting population of cells normally obtained from the bone marrow or peripheral blood. The use of Cell Expansion System provides for production of cells that can be infused to augment recovery of a compromised hematopoietic system. 1.2 The Cell Expansion System consists of (1) a disposable biochamber cartridge where the growth and expansion of cells takes place, (2) a biochamber incubation unit and companion monitor module that controls the biological and physical environment during the expansion process, (3) an inoculation/harvest unit that facilitates the initial filling and inoculation of cells as well as the final harvest of cells at the completion of the expansion process, (4) growth medium as required by the cell culture (to which specified growth factors and glutamine are added), (5) harvest reagents which facilitate the removal of the expanded cells from the biochamber, (6) a system rack will be available to conveniently integrate multiple biochamber incubation units with the monitor module. 1.2.1. The disposal biochamber cartridge (DBC) contains the medium contact components for the incubation period and provides a functionally closed environment in which the cell expansion can occur. The cartridge is provided fully assembled in a sterile package. In addition to a cell growth chamber, the medium contact components include a reservoir for medium supply, a pump mechanism for delivery of the medium to the growth chamber, valves to facilitate filling and harvesting, a reservoir for the collection of waste medium exiting the growth chamber, and a reservoir for the collection of harvested cells. The cartridge also includes a gas chamber which is supplied with a controlled mixture of gases for pH stability and oxygenation of the growth chamber through a gas permeable, hydrophobic membrane that separates the two chambers. 1 The cartridge also includes a provision for heat transfer to the growth chamber and away from the medium supply reservoir to facilitate temperature control. A biochamber key containing a non-volatile memory device is attached to the DBC at the beginning of use and accessed by the system electronics during the cell expansion process to record pertinent data. The key is detached after cell harvest, and archived as part of the patient specific cell expansion record. 1.2.2. The biochamber incubation unit (BIU) provides the biological and physical environment to support the cell growth process. The biochamber cartridge is inserted into the BIU after inoculation is complete. The BIU controls: the flow of medium to the growth chamber; the temperature of the growth medium supply compartment; the temperature of the growth chamber compartment; and the concentration and flow rate of gases delivered to the gas chamber. The BIU also monitors the density of cells in the growth chamber and various safety/alarm parameters to assure that the cell expansion process is proceeding as expected. The unit receives commands from keys on its front panel and communicates with the operator through a central BIU monitor module (BIUMM). An integral BIU display also provides information to the operator. Up to twelve biochamber incubation units can be connected to the monitor module. Each BIU has its own micro processor based control system and operates independently of the monitor module. As such, it will continue to function in the event of failure of the monitor module. 1.2.3. The inoculation/harvest unit (IHU) performs the initial filling of the biochamber cartridge with growth medium (supplemented with growth factors) and the inoculation of cells. The same unit also performs the removal of the cells from the growth chamber at the completion of the cell expansion process. The system design provides for the appropriate level of sterility assurance during the inoculation and harvest procedures. 1.2.3.1 During initial set up and fill, the operator loads the biochamber cartridge into the IHU, connects the medium supply (supplemented with growth factors) to the cartridge and transfer the medium to the internal reservoir. The operator is prompted to 2 manually inject the cells into the cartridge at the appropriate time. The process then continues under software control until the cartridge is ready to be placed in the biochamber incubation unit for cell expansion. 1.2.3.2. At the completion of the expansion process, the operator loads the biochamber back into the IHU, attaches the harvest reagents, and harvesting of the expanded cells proceeds under software control. At the completion of the harvest process, the expanded cell product is contained in a single bag to facilitate washing and preparation for direct infusion or cryopreservation. 1.2.4. The standard growth medium for the expansion of hematopoietic cells will be distributed as a separate item in packaging that will facilitate the addition of growth factors and glutamine followed by sterile connection to the biochamber cartridge just prior to use. 1.2.5. The harvest reagents needed for the process will be distributed as separate items in packaging that will facilitate an aseptic connection to the biochamber cartridge for cell harvest. 1.2.6. The system rack conveniently integrates several BIUs and a monitor module. The rack organizes connections to the facility and the inter connections between the various modules. The Instrument consists of the components described in paragraphs 1.2.2 (BIU), 1.2.3 (IHU), and 1.2.6 (Rack). 3 EXHIBIT B Functional Requirements and Specifications for the Instrument (to be added per Section 1.2) See generally Exhibit A. See also the SeaMED Project Plan, Drawing Number 908180, draft dated 2-2-94, which is incorporated herein.

    3.16  Acceptance; Payment Terms. Payment for each Order released to AASTROM
          ------------------------- 
shall be due forty-five (45) days following delivery and invoice, during which
period AASTROM shall perform its acceptance testing. IMMUNEX shall provide
AASTROM with descriptions of its release testing procedures and specifications
to permit AASTROM to conform its acceptance testing to the methods used by
IMMUNEX. If AASTROM provides evidence that such Order fails to meet the release
specifications set forth in the Manufacturing Regulatory Documentation that are
at that time in effect, payment shall not be due until the failure is corrected.
If the results of quality control testing by AASTROM do not agree with those
obtained by IMMUNEX, AASTROM shall promptly so notify IMMUNEX and the acceptance
period shall be extended forty-five (45) days to enable the parties to retest
the Order or otherwise attempt to reconcile their differences. In the event that
such differences cannot be resolved by the parties, the parties shall designate
an independent testing laboratory to test the Order. The findings of such
independent testing laboratory shall be binding on the parties, absent manifest
error. The expenses shall be borne by the party adversely affected by such
findings. IMMUNEX shall have no obligation to supply additional Orders of
Supplied Products to AASTROM if AASTROM declines to accept any Order due to the
application of any specifications or acceptance testing procedures that are
different from the release testing procedures and specifications employed by
IMMUNEX, if such Order otherwise complies with the procedures and specifications
employed by IMMUNEX. A late payment charge of 1% of the outstanding unpaid
balance per month shall be payable if invoiced charges are not paid when due.

    3.17  Facility Visits. Upon reasonable prior notice to IMMUNEX, AASTROM or

facilities owned or operated by IMMUNEX.

    3.18  Scheduling of Campaigns; Delays. IMMUNEX shall employ reasonable
          -------------------------------
commercial efforts to maintain inventories of all Supplied Products sufficient
to meet AASTROM's commercial requirements as specified in each Annual
Requirements Forecast. IMMUNEX shall promptly advise AASTROM of significant
unanticipated delays in the release of any Order. IMMUNEX shall not be liable to
AASTROM for any delay in providing any Order, or the documentation relating to
any Order, if such delay is caused by Force Majeure.

    3.19  Alternate Source of Supply. In the event that IMMUNEX elects to
          --------------------------
discontinue supplying AASTROM with any Supplied Product as provided in Section
3.8 above, or is prevented by Force Majeure from supplying AASTROM with any
Supplied Product for a period of at least one hundred eighty (180) days, IMMUNEX
shall use reasonable commercial efforts to grant AASTROM a nonexclusive license
to make or have made the Cytokine corresponding to such Supplied Product for use
or sale in the Field and Territory, transfer to AASTROM or its designee (which
could include, for example, a mutually acceptable contract manufacturer) all
Licensed Technology and any available license rights (apart from facilities,
commercially available raw materials or equipment) that are necessary or useful
in manufacturing such Cytokine in an alternative facility, and shall use
reasonable commercial efforts to cooperate with AASTROM to continue to supply
Supplied Product from its inventories to meet AASTROM's requirements for
Supplied Product until an alternate source of supply is established. IMMUNEX
shall not be obligated to grant such licenses or transfer any technologies in
the event that a dispute over acceptance procedures or specifications cannot be
resolved as provided in Section 3.16 hereof, or IMMUNEX and AASTROM are unable
to resolve any dispute over pricing. In such event, AASTROM

                                       7

 
shall be entitled to terminate this Agreement, subject to the liquidated damages
provisions of Section 8.4 hereof.

IMMUNEX has commenced negotiations with American Cyanamid Company and American
Home Products Corporation ("AHP") to obtain rights under prior agreements with
such companies enabling IMMUNEX to grant the Expanded Territorial Rights to
AASTROM. IMMUNEX shall continue such negotiations, and any other negotiations
that it deems reasonably necessary to secure appropriate licenses and rights
necessary to extend and protect such Expanded Territorial Rights. Pending
resolution of such negotiations, IMMUNEX will not object to the commencement of
any clinical trials by AASTROM outside of the Territory using Supplied Products
sold to AASTROM in the Territory. If such negotiations are successful, IMMUNEX
shall immediately amend this Agreement, at no additional charge or fee to
AASTROM, to grant AASTROM Expanded Territorial Rights.

prepare and file appropriate patent applications covering the disclosed
Improvement. Any patent rights resulting from such patent applications will be
included within the scope of Licensed Patent Rights.

    6.2  Notification and Abatement of Patent Infringement. AASTROM shall notify
         -------------------------------------------------
IMMUNEX of any infringement known to AASTROM by any Person of any Licensed
Patent Rights that apply also to operations of AASTROM, and shall provide
IMMUNEX with the available evidence, if any, of such infringement. If such
infringement is demonstrated by AASTROM to have resulted in competitive harm, or
would reasonably be

                                       9

 
expected to result in harm to AASTROM, AASTROM shall have the right to request
that IMMUNEX commence suit or otherwise abate such infringement. If, following
such notice, IMMUNEX has not commenced such suit within one hundred eighty (180)
days following such notice, AASTROM shall have the right to suspend payment of
any annual fees or royalties payable hereunder (but not any payments for
Supplied Products) until IMMUNEX commences such suit or otherwise abates the
infringement by licensing or otherwise. IMMUNEX shall not be obligated to
undertake any patent enforcement activities if AASTROM has not paid IMMUNEX
total annual fees equal to at least $3,500,000.

    IMMUNEX shall not be obligated to enforce Licensed Patent Rights against
more than one infringer at any one time.

    6.3  General Obligation of Confidentiality. During the Term and for a period

                                   THE TERM

3.01    Term:   The Term of this Lease and the payment of rent hereunder, shall
        ----
commence on the Commencement Date and shall end on the Expiration Date.

3.02    Commencement Date - Date Certain:   If item C1 of the Summary of Lease
        --------------------------------
Terms is checked and a date inserted, the Commencement Date shall be such date.
In that case Landlord agrees to substantially complete the improvements to the
Building listed on the Work Agreement executed by Tenant and Landlord and
attached as Rider B (the "Work Agreement") before the Commencement Date.

3.03    Commence Date - Substantial Completion:   If item C2 of the Summary
        --------------------------------------
Lease Terms is checked or if neither item C1 nor item C2 are checked, the
Commencement Date shall be as set forth in this Section 3.03.

        A. Notice of Substantial Completion. Landlord shall give Tenant ten (10)
           --------------------------------
        business days prior written notice of the anticipated date of
        substantial completion of the work to be performed by Landlord in the
        Premises pursuant to the provisions of the Work Agreement, which is
        attached hereto as Rider B (the "Work Agreement") and incorporated
        herein.

*See Rider D
            
                                      -3-

 
          The Premises shall be deemed substantially complete when Landlord has
          substantially completed the work required to be performed by Landlord
          for Tenant as provided in the Work Agreement.

          B. Delays. If there is a delay in the substantial completion of the
             ------
          Premises, or any portion thereof, due to (a) any act or omission of
          the Tenant, its architects, space designers, agents, or employees, as
          set forth in the Work Agreement including, without limitation, delays
          due to changes in the "Work" (as defined in the Work Agreement), or
          any other work to be done by the Landlord, or delays in submission of
          information, approving working drawings or estimates or giving
          authorizations or approvals, (b) any additional time for completion of
          such Work which may be required because of the inclusion in the Work
          of any work which may hereinafter be referred to in this Lease or the
          Work Agreement as "Additional Work" or (c) the noncompletion by the
          Landlord of any Work, whether in connection with the layout or finish
          of the Premises or otherwise, which the Landlord is not required to do
          by the terms hereof until after the Commencement Date; then, the
          Premises, or such portion, shall be deemed substantially complete and
          available for occupancy on the date when the Premises or such portion
          would have been available but for such delay, even though the Work or
          Additional Work to be done by Landlord has not been commenced or
          completed. Any reasonable and necessary additional cost to Landlord to
          complete the Premises occasioned by such delay shall be paid as
          additional rent upon demand. For the purposes of the preceding
          sentence, "additional cost to Landlord" shall mean the total cost
          incurred in excess of the aggregate cost which the Landlord would have
          incurred to complete the Premises if there had been no such delay.
          With respect to delays occasioned by the inclusion of "Additional
          Work" referred to in (b) above, Landlord shall advise Tenant in
          writing of the approximate number of days the Work will delay the
          substantial completion of the Premises.

          C. Termination. In the event the Premises shall not have been
             -----------
          substantially completed by Landlord on or prior to three months after
          the date of this Lease, as such date may be extended by reason of
          strikes, lockout, civil commotion, warlike operation, invasion,
          rebellion, hostilities, governmental regulations or controls,
          inability to obtain labor or materials despite reasonable diligence,
          Acts of God, or other similar causes beyond Landlord's control, then
          and in that event either Landlord or Tenant shall be entitled to
          cancel this Lease by written notice to the other and upon such
          cancellation, neither party shall have any further liability to the
          other hereunder.

3.04    Taking of Possession:  The taking of possession of the Premises shall be
        --------------------
deemed an acceptance of the same by Tenant, and shall be deemed in any event
substantial completion by Landlord of all of the improvements listed on the Work
Agreement. For the purposes of this Section, the work to be done by Landlord
shall be deemed substantially complete even though minor details or adjustments
which shall not materially interfere with Tenant's use and occupancy of the
Premises may not then have been completed, but which work Landlord agrees will
thereafter be promptly completed.

3.05    Waivers:  Tenant expressly waives any right to rescind this Lease and
        -------
further expressly waives the right to recover any damages, direct or indirect,
which may result from Landlord's failure to deliver possession of the Premises

        --------------------------
Landlord and Tenant will execute an agreement in recordable form, hereafter
referred to as the "Commencement Date Agreement", stating, among other things,
the Commencement Date and Expiration Date of the Term of this Lease. Tenant's
failure or refusal to sign the same shall in no event affect Landlord's
designation of the Commencement Date.

        -------------------
installments equal to the Base Monthly Rental, in advance, without any set-offs

day of each month (the "Rent Day") during the Term of this Lease at the address
shown in Paragraph I of the Summary, or at such other place as Landlord from
time to time may designate in writing. In the event the Commencement Date is

months included within the Lease Term and based upon the amount of the Base
Monthly Rental.

same are due will bear interest at a per annum rate of eleven (11%) percent; 
provided however, if such rate exceeds the maximum rate of interest permitted by
law under such encumbrances, then such rate shall be reduced to the 
maximum permissible rate. Such interest will be due and payable as additional 
rent on or before the next Rent Day, and will accrue from the date that such 
rent, late charges or other sums are first payable under the provisions of this 
Lease until actually paid by Tenant.

5.03    Default:  Any default in the payment of rent, late charges or other sums
        -------

hereunder are paid by Tenant to Landlord. If Tenant defaults in paying such late
charges and/or interest, Landlord will have the same remedies as on default in 
the payment of rent. The obligation hereunder to pay late charges and interest 
exists in addition to, and not in the place of, the other default provisions of 
this Lease.

                                  SECTION 15

                                EMINENT DOMAIN

15.01   Eminent Domain:  If the Premises or any part thereof are taken by any
        --------------
public authority under power of eminent domain, or by private

                                     -10-



 
sale in lieu of eminent domain, this Lease will terminate as of the date of such
taking or sale, and Tenant may receive a pro rata refund of any rents, deposits 
or other sums paid in advance.  Landlord reserves the right, however, to elect 
to demolish, rebuild or reconstruct the Building if any portion of the Building 
is so taken, and if Landlord so elects, whether or not the Premises are involved
in the taking, this Lease may be terminated by Landlord on 90 days written 
notice to Tenant and the rent will be adjusted to the date Tenant's 
possession of the Premises is terminated.

15.02   Condemnation Award:  The whole of any award or compensation for any 
        ------------------
portion of the Premises taken, condemned or conveyed in lieu of taking or 
condemnation shall be solely the property of and payable to Landlord.  Nothing 
herein contained shall be deemed to preclude Tenant from seeking at its own cost
and expense, an award from the condemning authority for loss of its business, 
the value of any trade fixtures or other personal property of Tenant in the 
Premises or moving expenses, provided that the award for such claim or claims 
shall not be in diminution of the award made to Landlord.

                                  SECTION 16

                           ASSIGNMENT OR SUBLETTING

16.01   Assignment or Subletting:  Tenant agrees not to assign or in any manner
        ------------------------
transfer this Lease or any interest in this Lease without the previous written
consent of Landlord, and not to sublet the Premises or any part of the Premises 
or allow anyone to use or to come in, with, through or under it without like 
consent, which consent, in each case, will not be unreasonably withheld.  Upon 
any attempted unconsented to assignment or sublease, Landlord shall have the 
right to terminate this Lease.  One such consent will not be deemed a consent to
any subsequent assignment, subletting, occupation or use by any other person.  
Any sublease on the Premises executed by Tenant and a third party must terminate
when the Term of this Lease expires.  The acceptance of rent from an assignee, 
subtenant or occupant will not constitute a release of Tenant from the further 
performance of the obligations of Tenant contained in this Lease.  In the event 
of any such assignment or sublease of all or any portion of the Premises where 
the rental or other consideration reserved in the sublease or by the assignment 
exceeds the rental or pro rata portion of the rental, as the case may be, for 
such space reserved in this Lease, Tenant agrees to pay Landlord monthly, as 
additional rent, on the Rent Day, the excess of the rental net of recovery of 
Tenant-paid improvement costs or other consideration reserved in the sublease 
or assignment over the rental reserved in this Lease applicable to the 
subleased/assigned space.

                                  SECTION 17

                 INSPECTION AND ALTERATION OF PUBLIC PORTIONS

17.01   Inspection:  Tenant agrees to permit Landlord and the authorized
        ----------
representatives of Landlord to enter the Premises at all times for the purpose 
of inspecting the same, subject to confidentiality agreements if requested by 
Tenant.

17.02   Right to Enter and Alter Premises:  Upon notice from Landlord, Tenant
        ----------------------------------
shall permit Landlord to erect, use and maintain pipes and conduits in and 
through the Premises.  Landlord or its agents or designees shall have the right 
to enter the Premises, for the purpose of making such repairs or alterations as 
Landlord shall be required or shall have the right to make by the provisions of 
this Lease and, subject to the foregoing, shall also have the right to enter the
Premises for the purpose of exhibiting them to prospective purchasers or lessees
of the Building or to prospective mortgages or to prospective assignees

                                     -11-



 
of any such mortgages.  Landlord shall be allowed to take all material into and 
upon the Premises that may be required for the repairs or alterations above 
mentioned without the same constituting an eviction of Tenant in whole or in 
part, and the rent reserved shall in no wise abate, except as otherwise provided
in this Lease, while said repairs or alterations are being made.

17.03   Right to Show Premises:  During the three (3) months prior to the 
        ----------------------
expiration of the Term of this Lease, Landlord may exhibit the Premises to 
prospective tenants during normal business hours.

17.04   Right to Alter Public Portions of Buildings:  Landlord shall have the
        -------------------------------------------
right at any time without thereby creating an actual or constructive eviction or
incurring any liability to Tenant therefore, to change the arrangement or
location of entrances, passageways, doors, and doorways, corridors, stairs,
toilets and other like public service portions of the Building. Tenant shall at
all times be provided with an entrance to the Premises.

17.05   Name of Building:  Landlord shall have the right at any time to name the
        ----------------
Building for any person(s) or tenant(s) and to change any and all such names at 
any time thereafter.

                            FIXTURES AND EQUIPMENT

18.01   Landlord's Property:  All fixtures and equipment paid for by Landlord
        -------------------
and all improvements, fixtures and equipment which may be paid for and placed on
the Premises by Tenant from time to time but which are so incorporated and 
affixed to the Premises that their removal would involve damage or structural 
change to the Premises, will be and remain the property of Landlord, excepting 
those items specifically listed in the Work Agreement.  Tenant will be 
responsible for the cost of repair due to removal of specified items.

18.02   Tenant's Property:  All improvements, furnishings, equipment and
        -----------------
fixtures other than those specified in Subsection 18.01, which are paid for and 
placed on the Premises by Tenant from time to time will remain the property of

                                  SECTION 19

                               UTILITY EXPENSES

        -----------

        (i) "Utility Expenses" means any and all charges for heat, air
        conditioning, ventilating, and steam, gas, electricity, water or
        other fuels made against the Entire Premises and all labor services
        and materials related thereto which are delivered or provided to or
        with respect to the Entire Premises.

        (ii) "Tenant's Proportionate Share of Utilities" means Utility Expenses
        multiplied by the percentage set forth in Paragraph G of the Summary.

        (iii) "Utility Expense Statements" means written statements, certified
        by Landlord, showing the amounts of Utility Expenses for each calendar
        year which includes any portion of the Term or any renewal or extension
        thereof.

19.02   Utility Expenses:  Tenant will pay to Landlord as Additional Rent $2.31 
        -----------------

                                     -12-



 
Payments due pursuant to this Section will be due at the time specified in 
Section 6.03.

19.03   Utility Expense Statement:  Any Utility Expense Statement sent to
        -------------------------
Tenant shall be conclusively binding upon Tenant unless, within thirty (30) days
after such statement is sent, Tenant shall send a written notice to Landlord 
objecting to such statement and specifying the respects in which such statement 
is claimed to be incorrect.  If such notice is sent, either party may refer the 
decision of the issues raised by such notice to Arthur Andersen & Co., or any 
successor firm, or other reputable independent firm of certified public 
accountants selected by Landlord, and the decision of such accountants shall be 
conclusively binding upon the parties.  The fees and expenses involved in such 
decision shall be borne by the unsuccessful party (and if both parties are 
partially unsuccessful, the accountants shall apportion such fees and expenses 
between the parties, based on the degree of success of each party).

                                  SECTION 20

                              NOTICES OR DEMANDS

20.01   Notices or Demands.  All bills, notices, statements, communications
        ------------------
or demands (collectively, "notices or demands") upon Landlord or Tenant desired 
or required to be given under any of the provisions hereof must be in writing.  
Any such notices or demands from Landlord to Tenant will be deemed to have been 
duly and sufficiently given if a copy thereof has been personally delivered or 
mailed by United States mail in an envelope properly stamped and addressed to 
Tenant at the address of the Premises or at such other address as Tenant may 
have last furnished in writing to Landlord for such purpose.  Any such notices 
or demands from Tenant to Landlord will be deemed to have been duly and 
sufficiently given if personally delivered to Landlord or mailed by United 
States mail in an enveloped properly stamped and addressed to Landlord at the 
address set forth in this Lease.  The effective date of such notice or demand 
will be deemed to be the time when personally delivered or mailed as herein 
provided.

                                  SECTION 21

                         BREACH;  INSOLVENCY; RE-ENTRY

21.01   Default:  If any rental payable by Tenant to Landlord remains unpaid
        -------
for more than seven (7) days after written notice to Tenant of nonpayment, or if
Tenant violates or defaults in the performance of any of its obligations in this
Lease and the 

                                     -13-

 
violation or default continues for a period of ten (10) days after written
notice, then Landlord may (but will not be required to) declare this Lease
forfeited and the Term ended, or re-enter the Premises, or may exercise all
other remedies available under Michigan law. Landlord will not be liable for
damages to person or property by reason of any legitimate re-entry or
forfeiture, and Landlord will be aided and assisted by Tenant, its agents,
representatives and employees. Tenant, by the execution of this Lease, waives
notice of re-entry by Landlord. In the event of re-entry by Landlord without
declaration of forfeiture, the liability of Tenant for the rent provided herein
will not be relinquished or extinguished for the balance of the Term, and any
rentals prepaid may be retained by Landlord and applied against the costs of re-
entry, or the costs of enforcement of this Lease, including the cost of any
proceeding under the Federal Bankruptcy Code.

21.02   Bankruptcy:  If Tenant is adjudged bankrupt or insolvent, files or 
        ----------
consents to the filing of a petition in bankruptcy under Federal or State law,
applies for or consents to the appointment of a receiver for all or
substantially all of its assets, or makes a general assignment for the benefit
of its creditors, then Tenant shall be in default under this Lease and, to the
extent from time to time permitted by applicable law, including but not limited
to the Federal Bankruptcy Code, Landlord shall be entitled to exercise all
remedies set forth in Section 21.01. In a reorganization under Chapter 11 of the
Federal Bankruptcy Code, the debtor or trustee must assume this Lease or assign
it within sixty (60) days from the filing of the proceeding, or he shall be
deemed to have rejected and terminated this Lease. Tenant acknowledges that its
selection to be the tenant hereunder was premised in material part on Landlord's
determination of Tenant's creditworthiness and the character of its occupancy
and use of the Premises would be compatible with the nature of the Premises and
other adjacent properties and tenants of Landlord. Therefore, if Tenant, as
debtor, or its trustee elects to assume this Lease, in addition to complying
with all other requirements for assumption under the Federal Bankruptcy Code,
then Tenant, as debtor, or its trustee or assignee, as the case may be, must
also provide the adequate assurance of future performance, including but not
limited to a deposit, the amount of which shall be reasonably determined based
on the duration of time remaining in the Term, the physical condition of the
Premises at the time the proceeding was filed, and such damages as may be
reasonably anticipated after reinstatement of the Lease.

21.03   Re-Leasing of Premises:  In the event of declaration of forfeiture
        ----------------------
at or after the time of re-entry, Landlord may re-lease the Premises or any 
portion(s) of the Premises for a term or terms and at a rent which may be less 
than or exceed the balance of the term of and the rent reserved under this 
Lease.  In such event Tenant will pay Landlord as liquidated damages for 
Tenant's default any deficiency between the total rent reserved and the net 
amount, if any, of the rents collected on account of the lease or leases of the 
Premises which otherwise would have constituted the balance of the term of this 
Lease.  In computing such liquidated damages, there will be added to the 
deficiency reasonable expenses which Landlord may incur in connection with 
re-leasing, such as legal expenses, attorney's fees, brokerage fees and 
expenses, advertising and for keeping the Premises in good order or for 
preparing the Premises for re-leasing.  Any such liquidated damages will be paid
in monthly installments by Tenant on the Rent Day and any such suit brought to 
collect the deficiency for any month will not prejudice Landlord's right to 
collect the deficiency for any subsequent month by a similar proceeding.  In 
lieu of the foregoing computation of liquidated damages, Landlord may elect, at 
its sole option, to receive

                                     -14-

 
liquidated damages in one payment equal to any deficiency between the total rent
reserved hereunder and the fair and reasonable rental of the Premises, both 
discounted at five (5%) percent per annum to present value at the time of 
declaration of forfeiture.

21.04   Failure to Re-Lease Premises:  Whether or not forfeiture has been 
        ----------------------------
declared, Landlord will attempt to re-lease the Premises, however, Landlord will
not be responsible in any way for failure to re-lease the Premises, or in the 
event that the Premises are re-leased, for failure to collect the rent under 
such re-leasing.  The failure of Landlord to re-lease all or any part of the 
Premises will not release or affect Tenant's liability for rent or damages.

                                  SECTION 22

                     SURRENDER OF PREMISES ON TERMINATION

22.01   Condition of Premises Upon Termination:  At the expiration (or earlier
        --------------------------------------
termination) of the Term, Tenant will surrender the Premises broom clean and in
as good condition and repair as they were at the time Tenant took possession,
reasonable wear and tear excepted, and promptly upon surrender will deliver all
keys and building security cards for the Premises to Landlord at the place then
fixed for payment of rent. All reasonable costs and expenses incurred by
Landlord in connection with repairing or restoring the Premises to the condition
called for herein, together with the costs, if any, of removing from the
Premises any property of Tenant left therein, together with liquidated damages
in an amount equal to the amount of minimum net rental plus all other charges
which would have been payable by Tenant under this Lease if the term of this
Lease had been extended for the period of time reasonably required for Landlord
to repair or restore the Premises to the condition called for herein, shall be
invoiced to Tenant and shall be payable within ten (10) days of the date of such
invoice.

22.02   Storage of Tenant's Property:  If Tenant fails to remove all its 
        ----------------------------
property (or property of others in its possession) from the Premises on 
termination of this Lease (for any cause), Landlord at its option may remove the
property in any manner that it chooses and may store the property without 
liability to Tenant for loss, whether based on contract, tort or otherwise.  
Tenant agrees to pay Landlord on demand any and all expenses incurred in such 
removal, including court costs, attorneys' fees and storage charges on the
property for any length of time it is in Landlord's possession. Tenant will
indemnify and hold Landlord harmless from any claim by third parties with
respect to property owned or claimed by them, left in the Premises by Tenant,
and removed by Landlord pursuant to this paragraph. Under no circumstances will
Landlord be obligated to retain any property left on the Premises or in
Landlord's possession longer than two (2) months after termination of this Lease
(for any cause) and Landlord may after two (2) months dispose of the property in
any manner it deems appropriate, including public or private sale or by
destruction, discard or abandonment and the proceeds of any such sale will be
applied against any sums due Landlord under this Lease.

                                  SECTION 23

              PERFORMANCE BY LANDLORD OF THE COVENANTS OF TENANT

23.01   Tenant's Failure to Perform:  If Tenant fails to pay any sum of money, 
        ----------------------------
other than rental, required to be paid hereunder or fails to perform any act on 
its part to be performed hereunder and such failure shall continue for a period 
of ten (10) days (or a reasonable period of less than ten (10) days when life, 
person or property is in jeopardy), Landlord may (but shall

                                      -15-


 
not be required to), and without waiving or releasing Tenant from any of 
Tenant's obligations, make any such payment or perform any such other act.  All 
sums paid by Landlord and all reasonable incidental costs, including without 
limitation the cost of repair, maintenance or restoration of the Premises if so 
performed by Landlord hereunder, shall be deemed additional rental and, together
with interest thereon at the rate set forth in Section 5.02 from the date of 
payment by Landlord until the date of repayment by Tenant to Landlord, shall be 
payable to Landlord within fifteen (15) days after receipt of invoice by Tenant.
On default in such payment, Landlord shall have the same remedies as on default
in payment of rent.  The rights and remedies granted to Landlord under this 
Section 23 shall be in addition to and not in lieu of all other remedies, if 
any, available to Landlord under this Lease or otherwise, and nothing herein 
contained shall be construed to limit such other remedies of Landlord with 
respect to any matters covered herein.

                                  SECTION 24

                     SUBORDINATION; ESTOPPEL CERTIFICATES

24.01   Subordination:  Tenant agrees, that at Landlord's option, this Lease may
        -------------
be either subordinate or paramount to any construction loans, mortgages, trust 
deeds and ground or underlying leases now or hereafter affecting the Premises 
and to any and all advances to be made thereunder, and to the interest and 
charge thereon, and all renewals, replacements and extensions thereon, provided 
the mortgagee, lessor or trustee named in any such mortgages, trust deeds or 
leases agrees to recognize the lease of Tenant in the event of foreclosure or 
other enforcement of such instruments (and, if requested by Tenant, shall enter 
into a non-disturbance agreement with Tenant) if Tenant is not in default.  
This section shall be self-operative and no further instrument shall be 
required.  However, Tenant will execute promptly any instrument or certificate 
that Landlord may reasonably request confirm such subordination or superior 
status, subject to Tenant's receipt of a non-disturbance agreement, if so 
requested, and hereby irrevocably appoints Landlord as Tenant's attorney-in-fact
to execute such instrument or certificate on its behalf.

                                QUIET ENJOYMENT

26.01   Quiet Enjoyment:  Landlord agrees that at all times when Tenant
        ---------------
is not in default under the provisions and during the Term of this Lease, 
Tenant's quiet and peaceable enjoyment of the Premises will not be disturbed or 
interfered with by Landlord or any person claiming by, through, or under 
Landlord.

                                  SECTION 27

                                 HOLDING OVER

27.01   Holding Over:  If Tenant remains in possession of the Premises after 
        ------------
expiration of this Lease without executing a new lease, it will be deemed to be 
occupying the Premises as a tenant from month-to-month, subject to all the 
provisions of this Lease to the extent that they can be applicable to a 
month-to-month tenancy, except that the minimum rental for each month will be 
one hundred percent (100%) of the Base Monthly Rental.

                                  SECTION 28

                        REMEDIES NOT EXCLUSIVE; WAIVER

28.01   Remedies:  Each and every of the rights, remedies and benefits provided
        ---------
by this Lease are cumulative and are not exclusive of any other of said rights, 
remedies and benefits, or of any other rights, remedies and benefits allowed by 
law.

28.02   Waiver of Covenant:  One or more waivers of any covenant or condition by
        ------------------
Landlord will not be construed as a waiver of a further or subsequent breach of 
the same covenant or condition, and the consent or approval by Landlord to or of
any act by Tenant requiring Landlord's consent or approval will not be deemed to
waive or render unnecessary Landlord's consent to or approval of any subsequent 
similar act by Tenant.

                             WAIVER OF SUBROGATION

29.01   Waiver of Subrogation:  Landlord and Tenant shall obtain permission

right of recovery against each other for any loss or damage caused by fire or 
any of the risks covered by standard fire and extended coverage, vandalism and 
malicious mischief insurance policies.

                                  SECTION 30

Landlord and its licensees, servants, agents, employees and contractors, 
harmless from any claim or condition of the Premises, the use or misuse thereof 
by Tenant or any other person, the acts or omissions of Tenant, its clients, 
customers, invitees, licensees, servants, agents, employees or contractors, the 
failure of Tenant to comply with any provision of this Lease, or any other event
occurring on the Premises, whatever the cause; provided, however, that nothing 
herein shall be construed to require Tenant to indemnify Landlord or its 
licensees, servants, agents, employees, and contractors against Landlord's or 
its licensees' servants' agents', employees' and contractors' own acts, 
omissions or neglect.

31.01   Assignment by Landlord: The term "Landlord" as used in this Lease so 
        ----------------------
far as covenants, agreements, stipulations or obligations on the part of the 
Landlord are concerned is limited to mean and include only the owner or owners 
of fee title (or of a ground leasehold interest or land contract vendee's 
interest) to the Premises at the time in question, and in the event of any 
transfer or transfers of the title to such fee the Landlord herein named (and 
in case of any subsequent transfers or conveyances the then grantor) will 
automatically be freed and relieved from and after the date of such transfer or 
conveyance of all liability for the performance of any covenants or obligations 
on the part of the Landlord contained in this Lease thereafter to be performed.

31.02   Landlord's Default:  If Landlord fails to perform any provision of this 
        ------------------
Lease upon Landlord's part to be performed, and if as a consequence of such
default Tenant recovers a money judgment against Landlord, such judgment may be

                                --------------

        The terms and conditions of this Work Agreement shall govern Landlord
and Tenant's participation in the design, construction and installation of
improvements to the Premises in accordance with the Final Plans (as defined
below) and the terms hereof (the "Work"). Tenant acknowledges that it has had an

improvements to the Premises to the completed at Landlord's expense have been
completed and are accepted by Tenant in an "As Is" condition except for work to

improvements to the Premises and services incidental or related thereto are
referred to as "Work" and shall be paid for by Landlord and Tenant as set forth
herein.

A.      PRE-LEASE WORK
        --------------

        1.  Preliminary Drawings. Landlord and Tenant acknowledge that they have
            --------------------
            agreed on preliminary drawings prepared by H. Scott Diels,
            Architect, at Tenant's direction and containing general design and
            technical information for the Work to be performed on the Premises
            (the "Preliminary Drawings"), copies of which are attached to this
            Lease as Rider A-2, May 4, 1992. The Preliminary Drawings have been

            ----------------------------
            Engineer and Contractor that Landlord will assume responsibility for

            Lease and that Landlord will be, and perform the obligations of the
            "Owner" under the Architect Agreement, the Engineer Agreement and
            the Construction Agreement. Tenant shall cooperate with Landlord and
            assist in the transition of responsibility for administration and
            coordination of the Work. Landlord and Tenant agree that all
            communications with, and instructions or directions to, the
            Architect, Engineer and Contractor after transition of the Work to
            the Landlord will go through Landlord.

            -------------------------
            with administration of the Work shall be Larry McGonigal unless
            otherwise directed in writing by Landlord ("Landlord's
            Representative"). All instructions, requests, or directives from
            Tenant to the Landlord, Architect, Engineer or Contractor in
            connection with the construction of the Work will be given or
            communicated to Landlord's Representative who will in turn contact
            or notify the appropriate party.

        2.  Tenant's Representative. Tenant's representative in connection with
            -----------------------
            the Work shall be R. Douglas Armstrong unless otherwise directed in
            writing by Tenant ("Tenant's Representative"). All requests,
            notification, directives, inquiries or information intended for
            Tenant shall be given or communicated by Landlord or Landlord's
            Representative to Tenant's Representative. Tenant's Representative
            shall have access to the Work at all reasonable times for the
            purpose of making inspections, taking measurements and observing the
            Work and may inspect, copy, and discuss with Landlord's
            Representative or other appropriate personnel of Landlord from time
            to time the Work and all invoices and documentation in connection
            with the Work, Tenant's Representative shall be requested to attend
            all regularly scheduled progress meetings related to the Work.

        3.  Field Change Orders. Tenant's Representative shall have the right to
            -------------------
            request Field Change Orders in writing. For purposes of this
            section, "Field Change Orders" shall mean: (a) a "Change Order" or
            "Field Work Order" (as defined in the Contractor Agreement) or
            similar request for changes or modifications in the Work; or (b)
            revisions to the Final Plans or other work-related documents or
            materials requested by Tenant.

        4.  Approval of Field Change Orders. All Field Change Orders shall be
            -------------------------------
            approved in writing by both Landlord and Tenant and shall be
            acceptable to


 
             Landlord and Tenant in all respects. The cost of any Field Change
             Order shall be an additional Work Cost. Tenant's Representative
             shall approve all Field Change Orders, changes or modifications to
             the Final Plans and any design changes to the Work. Tenant's
             Representative, on behalf of Tenant, and Landlord's Representative,
             on behalf of Landlord, will promptly respond to any requests or
             inquiries of Landlord or Tenant, as the case may be, including
             those relating to Field Change Orders, so as not to interfere with
             the orderly progress of the Work. Landlord shall have the right to
             reject any Field Change Order requested by Tenant which,
             individually or in the aggregate, would delay the Commencement Date
             of the term of this Lease in excess of fourteen (14) days, unless
             in conjunction therewith, Tenant agrees to pay rental for the
             Premises as of the date the Commencement Date would have occurred
             but for the completion of the Field Change Order. The Landlord's
             and Tenant's reasonable judgement as to whether delay may ensue as
             a result of Tenant requested Field Change Orders shall be
             conclusive.

          5. Other Tenant Employee's. Officers, employees or agents of Tenant
             -----------------------
             other than Tenant's Representatives shall have access to the Work
             provided that Tenant notifies Landlord's Representative in advance
             and Tenant's Representative or his designee in writing accompanies
             such parties during such access. Landlord may deny access to such
             parties excluding Tenant's Representative (but access by Tenant's
             Representative shall nevertheless be subject to the delay
             provisions in Section 3.03 of the Lease) in the event that their
             presence materially hampers, interferes with or prevents Landlord,
             Architect, Engineer or Contractor from proceeding with the
             completion of the Work. Any entry on the Premises by Tenant's
             Representative and other officers, agents, employees,
             representatives, licensees or invitees of Tenant shall be at their
             sole risk. Tenant hereby agrees to indemnify, defend and hold
             Landlord harmless from and against any loss, expense, claim,
             demand, action or proceeding arising out of or relating to such
             access to the Premises other than such losses, expenses, claims,
             demands, actions, proceedings caused by the negligence, gross
             negligence or willful misconduct of Landlord or its directors,
             officers, employees, agents, servants, representatives, invitees or
             licensees other than any party performing services under the
             Contractor Agreement, Architect Agreement or Engineer Agreement.

          6. Consultation/Cooperation. Landlord shall advise Tenant of, and
             ------------------------
             consult with Tenant regarding, all material matters relating to the
             Work, including, without limitation, the design, construction and
             engineering of the Work, as well as the services performed or to be
             performed by the Architect, Engineer and Contractor. Tenant shall
             reasonably cooperate with Landlord with respect to such
             consultations and shall not act or fail to act in a manner which
             will delay the design or construction of the Work. Landlord agrees
             to use reasonable efforts to cause Architect, Engineer, Contractor
             and all other persons working on or in connection with the Work to
             perform and comply with terms of this Agreement and any other
             applicable agreement (including, without limitation, pursuing any
             applicable legal recourse against such persons). If any one or more
             Architect, Engineer or Contractor breach their respective contracts
             with Landlord described herein, Landlord may, but shall not be
             obligated to, commence civil proceedings to obtain specific
             enforcement of such breached contract and/or for any other remedies
             or damages available to Landlord. In the event of such a breach and
             if Landlord fails or refuses to commence such legal proceedings
             against the breaching party for sixty (60) days, Tenant may
             commence civil proceedings, at Tenant's sole expense, for specific
             enforcement of the breached contract or any other remedies or
             damages available to Tenant, and to the extent necessary to permit
             and prosecute such proceedings Landlord will assign its rights
             under the breached contract or contracts to Tenant and reasonably
             cooperate with Tenant in connection therewith.

                 Drawings shall contain design, technical and engineering
                 specifications for the Work based on the Preliminary Drawings.
                 Landlord shall negotiate and execute, as Owner, the written
                 agreement with the Architect governing Architect's
                 participation in the Work (the "Architect Agreement"). All
                 Preliminary Services performed by the Architect shall be
                 included in and made a part of and subject to the terms and
                 conditions of the Architect Agreement. Landlord shall provide,
                 upon request, Tenant with a copy of the proposed Architect
                 Agreement and


 
                         shall consult with, and include reasonable suggestions
                         of, Tenant with respect to the terms and conditions of
                         the Architect Agreement prior to execution thereof.
                         Landlord shall be, and perform the obligations of, the

                         submit the Preliminary Drawing to the Architect for
                         preparation of the Formal Drawings. Landlord and Tenant
                         shall each have a period of seven (7) days after
                         receipt of the Formal Drawings to 1) approve such
                         drawings in writing, or 2) send written notice to the
                         other party describing any objections to the Formal
                         Drawings. In the event either Landlord or Tenant sends
                         a notice of objections to the formal Drawings, Landlord
                         and Tenant will meet within seven (7) days after such
                         notice is sent to discuss and resolve those matters
                         objectionable to Landlord or Tenant. Either Landlord or
                         Tenant may request the presence of the Architect at
                         such meeting. Landlord and Tenant agree to use their
                         good faith efforts in negotiating and preparing revised
                         Formal Drawings, but the Formal Drawings must be
                         acceptable to both Landlord and Tenant in all respects.
                         The Architect shall revise the Formal Drawings in
                         accordance with those modifications which are approved
                         by Landlord and Tenant at such meeting. The revised
                         Formal Drawings shall reflect the agreed to
                         modifications and shall be given to Tenant and Landlord
                         for final approval. Tenant and Landlord shall give
                         final approval of the Formal Drawings in writing within
                         seven (7) days after receipt of satisfactory Formal
                         Drawings which reflect the agreed to modifications (the
                         Formal Drawings, once so approved, are referred to as
                         "Final Plans").

                     (c) Landlord's Insurer. The Final Plans, once completed,
                         ------------------
                         shall be sent to Factory Mutual Insurance Company, the
                         Landlord's Insurer, ("Insurer") for review and

              Landlord shall assign to Tenant those warranties and manuals with
              respect to those items described in Rider H to this Lease and such

              such warranties (at Tenant's cost and expense). LANDLORD HEREBY

    To the fullest extent permitted by law, Tenant agrees to defend,
    indemnify and hold Landlord, its partners, employees, officers, and agents,
    and their legal successors and assigns (herein the "Landlord Indemnitees"),
    free and harmless of and from any and all liability, damages, all losses,
    costs and expenses, including, without limitation, all Work Cost and
    attorney fees, (collectively "Losses") incurred, suffered or required to
    be paid by Landlord Indemnitees to the extent that such losses result from
    or are attributable to (a) Tenant's failure to pay the Work Cost due and
    payable pursuant to this Work Agreement or (b) Landlord's Indemnitees'
    reliance on orders, instructions, directives or requests of Tenant in 
    connection with the construction of the Work and the preparation of the
    Final Plans or (c) any negligent or grossly negligent acts, or omissions
    and/or intentional malfeasance, of Tenant, its employees, agents, guests
    or invitees prior to final completion of the Work, provided however, that
    notwithstanding anything herein to the contrary, the foregoing obligation
    to indemnify, hold harmless and defend shall not apply to any liability,
    damages, losses, costs or expenses attributable to the Landlord's
    Indemnitees.  If any claim is made by a third party against any Landlord
    Indemnitees for which the Landlord Indemnitee seeks indemnification from
    Tenant hereunder, Landlord shall give prompt notice to Tenant who shall 
    have the right at Tenant's sole expense to participate in or control the
    defense of such claim at its own expense and through counsel of its own 
    choice.  If after such notice Tenant does not so participate, Tenant shall
    nevertheless be bound by the results obtained by Landlord insofar as the
    claim against any Landlord Indemnitee is concerned.

    attorney fees, incurred, suffered or required to be paid by Tenant
    Indemnitee, resulting from or caused by or arising out of any action,
    omission or operation (i) under this Agreement or in connection with the
    Work attributable to Landlord, (ii) under the Architect Agreement, the
    Engineer Agreement, the Contractor Agreement or any other construction
    related document attributable to Landlord or the performance of any
    obligation of Landlord under such agreements or documents, or (iii) relating
    to any claim against Tenant arising under the Architect Agreement, the
    Engineer Agreement, the Contractor Agreement or any Work related document
    provided, however, that the foregoing obligation by the Landlord to defend,
    indemnify and hold harmless shall not apply to (x) any liability, damages,
    losses, costs or expenses, attributable to the negligence, gross negligence
    or willful misconduct of any Tenant Indemnitee, (y) the breach of any
    obligation of Tenant hereunder or (z) those matters for which Tenant is
    obligated to indemnify Landlord pursuant to Section B(5) of this Work
    Agreement. If any claim is made by a third party against any Tenant
    Indemnitee for which the Tenant Indemnitee seeks indemnification from
    Landlord hereunder, the Tenant Indemnitee shall give prompt notice to
    Landlord who shall have the right, at its sole option, to participate in or
    control the defense of such claim at its own expense and through counsel of
    its own choice. If after such notice Landlord does not so participate,
    Landlord shall nevertheless be bound by the results obtained by Tenant

        Summary of Lease Terms.  Approvals of such documents shall be sent
        in accordance with Section 20 of the Lease relating to notices.

    2.  Relationship.  Landlord and Tenant agree that Landlord is not the
        ------------
        employee or agent of Tenant and with respect to this Work Agreement
        is an independent contractor.  It is expressly agreed that all persons
        engaged in the 


 
     performance of the Work hired by Landlord or by any contractor of Landlord
     as between Landlord and Tenant shall be conclusively deemed to be employees
     or contractors of Landlord and not Tenant. This Agreement shall not
     constitute Landlord or any contractor as the agent, partner, or legal
     representative of Tenant, and Tenant shall not be responsible in any way
     for any obligations or liability incurred or assumed by Landlord or any
     contractor (the foregoing shall not in any manner limit the liability of
     obligations of Tenant to Landlord hereunder). Landlord shall contract only
     in its own name and only for its own account. Each such contract shall
     expressly state that the contractor recognizes that, to the extent
     permitted by law, it does not have a right to make any claim for payment
     directly from Tenant, since the contract has been made exclusively with
     Landlord and that, upon the request of Landlord, the contractor shall
     provide Landlord with a sworn statement regarding the contractor's right to
     receive payments for work or materials provided to the Work.

 3.  Confidentiality of Work and Plans. Landlord agrees that Landlord will
     ---------------------------------
     maintain the confidentiality of, and not disclose to third persons or
     parties, any of the Final Plans, Field Change Orders or other plans or
     specifications relating the Work except as Landlord may require for the
     construction of the Work, maintenance, operation, financing, insuring, sale
     of other conveyance of the Building or as may be required by any
     governmental authority, department or agency.

shall have a First Right of Refusal ("Right of Refusal") to lease certain 
additional space in the Building, under the following terms and conditions:

alternative space for any leasing prospects interested in approximately 2,300
square feet.

    B.  Exercise by Tenant.  Tenant shall have the right to exercise its Right 
of Refusal in the following manner:  If at any time after the date hereof, the 
space is vacant, and Landlord intends to let such vacant space, as evidenced by 
a written proposal from Landlord (Landlord's Proposal) to a proposed lessee, 
then Landlord shall give Tenant written notice of such intention (Notice of 
Intent to Lease).  Tenant shall have a period of ten (10) business days from the
date of receipt of such Notice of Intent to Lease to exercise its Right of 
Refusal by sending written notice to Landlord of such exercise (which notice 
must be received by Landlord within such ten (10) day period).

    C.  Refusal by Tenant.  If Tenant does not exercise its Right of Refusal as 
to the space covered by a Landlord's Proposal, Landlord shall be free to lease 
the space pursuant to the Landlord's Proposal.

    If Tenant does not exercise its Right of Refusal and the proposed lessee 
does not accept the Landlord's Proposal, Tenant's Right of Refusal with respect 
to such space shall be reinstated as set forth above, including, without 
limitation, the right to exercise its Right of Refusal as to any subsequent 
proposals to lease the space as set forth above.

    D.  Notices.  All notices hereunder shall be sent in compliance with Section
20 of the Lease.

    E.  Same Lease Terms.  Under the exercise of Tenant's Right of Refusal, the 
space affected thereby shall be subject to all of the same terms and conditions 
of this Lease (including, without limitation, the Renewal Option set forth above
and the Expiration Date) except that (i) additional rent with respect to such 
space shall commence ninety (90) days after the exercise of Tenant's Right of 
Refusal relating to such space, or upon taking possession of such space, if 
sooner; and (ii) Base Annual Rent and Base Monthly Rent for the additional space
taken by Tenant shall be at the same rate in effect for the Premises at the time

                                  ----------

1.  Attornment.  Tenant covenants and agrees that, if by reason of default
    ----------
    under any mortgage which may now or hereafter affect the Premises,
    including, without limitation, the Mortgage and Security Agreement dated as
    of March 29, 1990, between the owner of the Premises hereunder or a
    successor in title or interest, as Mortgagor, and Kansallis-Osake-Pankki,
    New York Branch, as Mortgagee, and any amendments, supplements or
    modifications thereof (the "Mortgage"), the mortgagee thereunder enters into
    and becomes possessed of the mortgaged property of which the Premises form a
    part either through possession or foreclosure action or proceeding, or in
    the event of the sale of the said action or proceeding, or in the event of
    the sale of the said mortgaged property as a result of any action or
    proceeding to foreclose said mortgage or as a result of a conveyance in lieu
    of foreclosure, the Tenant will attorn to the mortgagee or such then owner
    as its Landlord under this Lease, unless the mortgagee or such then owner
    shall elect to terminate this Lease and the rights of the Tenant hereunder.
    The Tenant agrees to execute and deliver, at any time and from time to time,
    upon the request of the mortgagee or the then owner of the mortgaged
    property, any instrument which may be necessary or appropriate to evidence
    such attornment and the Tenant hereby appoints the mortgagee or the then
    owner of the Premises the attorney-in-fact, irrevocable, of the Tenant to
    execute and deliver for and on behalf of the Tenant any such instrument. The
    Tenant further waives the provision of any statute or rule of law now or
    hereafter in effect which may terminate this Lease or to surrender
    possession of the Premises in the event of foreclosure or any proceeding is
    brought by the mortgagee under any such mortgage to terminate the same, and
    agrees that unless and until the mortgagee, in connection with any such
    proceeding, shall elect to terminate this Lease and the rights of the Tenant
    hereunder, this Lease shall not be affected in any way whatsoever by any
    such proceeding.

2.  Nondisturbance.  Notwithstanding the provisions of Paragraph 1 above:
    --------------
    (a)  The mortgagee or the then owner, as the case may be, shall not disturb
         Tenant's use and possession of the Premises nor terminate the Lease so
         long as Tenant is not in default of the terms of this Lease.

    (b)  In addition, the mortgagee or the then owner, as the case may be, shall
         at all times during Tenant's attornment hereunder, be bound to Tenant  
         as Landlord under all the terms and conditions of this Lease, provided,
         however, that the mortgagee or the then owner, as the case may be,
         shall not be (i) liable for the act or omission of any prior landlord
         under the Lease (including Landlord); (ii) subject to any offsets or
         defenses which Tenant might have against any prior landlord under the
         Lease (including Landlord); (iii) bound by any rent or additional rent
         which Tenant might have paid for more than the current month to any

         or additional rent has been delivered to mortgagee or such then owner;
         (iv) responsible for any security deposit which Tenant may have paid
         to any landlord (including Landlord), unless such deposit has been
         delivered to the mortgagee or such then owner, or (v) bound by any
         modification, amendment, surrender or cancellation of the Lease made
         without the prior written consent of mortgagee or the then owner.

                              -------------------

HAZARDOUS MATERIALS/TENANTS OBLIGATIONS
- ---------------------------------------

A.  Definitions:  As used in this Section, "Environmental Law" and
    -----------
    "Hazardous Materials" shall have the following meanings:

    1.  "Environmental Law" means any applicable federal, state or local
        ------------------
        government law, rule, ordinance or regulation in effect from time
        to time relating to the environment, pollution, toxic substances,
        Hazardous Materials or solid and/or toxic waste disposal, including,

             Liability Act of 1980; and

        (e)  Federal Superfund Amendments and Reauthorization Act of 1986.

        Recovery Act of 1976, the Comprehensive Environmental Response,
        Compensation Liability Act of 1980 and the Superfund Amendments and
        Reauthorization Act of 1986.

B.  Use of Premises.  Tenant shall not cause or permit the Premises to be used
    ---------------
    to generate, manufacture, refine, transport, treat, store, handle, dispose 
    of, transfer, produce or process Hazardous Materials in violation of any
    Environmental Law.  At all times Tenant shall use and dispose of Hazardous
    Materials in compliance with all applicable Environmental Law and all
    requirements and guidelines of the United States Nuclear Regulatory 
    Commission.  Tenant shall not cause or permit, as a result of any
    intentional or unintentional act or omission on the part of Tenant, a 
    release of Hazardous Materials onto the Premises, the Building or any area
    comprising part of the Domino's Farms Prairie House Office Complex in
    violation of Environmental Law.  Landlord and Tenant will promptly deliver
    to the other copies of all notices received from any federal, state or local
    authority regarding environmental problems affecting the Premises.  The
    provisions hereof shall be in addition to any and all other obligations
    and liabilities Tenant may have to the Landlord at law or in equity 
    regarding Tenant's violation of Environmental Law and shall survive
    termination of this Lease and the satisfaction of all other obligations
    of Tenant hereunder.

C.  Presence of Hazardous Materials/Indemnity.  If Hazardous Materials are
    -----------------------------------------
    present on or under the Premises in amounts, concentrations or in a manner
    in violation of Environmental Law by reason of the acts or omissions of
    Tenant or its agents, representatives, contractors, officers, directors,
    employees, licensees or invitees, Tenant shall: (i) conduct and complete all
    investigations, studies, sampling and testing, and all remedial, removal and
    other actions necessary to clean up and remove all such Hazardous Materials
    on, under, from or affecting the Premises in accordance with all applicable
    Environmental Law; (ii) defend, indemnify and hold harmless Landlord, its
    employees, agents, officers and directors from and against any claims,
    demands, penalties, fines, liabilities, settlements, damages, costs or
    expenses (including attorney's fees) of whatever kind or nature, known or
    unknown, contingent or otherwise, arising out of or in any way related
    to: (A) the presence, disposal, release or threatened release of any such
    Hazardous Materials on, over, under, from or affecting the Premises or the
    soil, water, vegetation, buildings, personal property, persons or animals
    on, in, over or under the Premises; (B) any personal injury (including
    wrongful death) or
    





 
    property damage (real or personal) arising out of or related to such
    Hazardous Materials; (C) any lawsuit brought or threatened, settlement
    reached or government order relating to such Hazardous Material; and/or (D)
    any violation of laws, orders, regulations, requirements or demands of
    government authorities, or any reasonable policies or requirements of
    Landlord (and in the case Landlord's requirements of which Tenant was
    provided prior written notice), which are based upon or in any way related
    to such Hazardous Materials, including, without limitation, reasonable
    attorney's and reasonable consultant's fees, investigation and laboratory
    fees, court costs and out-of-pocket litigation expenses. In no event shall
    Tenant have any liability for: (i) conditions not in existence on the day
    Landlord, its successors or assigns, takes possession of the Premises from
    Tenant, (ii) conditions existing prior to the date Tenant takes possession
    of the Premises, or (iii) conditions aggravated or worsened (but only to the
    extent so aggravated or worsened) by Landlord, or its successors, assigns or
    any third party, after the date Landlord or its successors and assigns takes
    such possession of the Premises. Landlord shall give Tenant prompt notice of
    any claim or information of which Landlord has knowledge that is likely to
    give rise to a claim for defense, indemnity or hold harmless under this
    Section, and shall permit Tenant's involvement in the defense of any such
    claim as reasonably requested by Tenant. Neither Landlord nor Tenant shall
    settle or pay any third party claim with respect to any claim hereunder,
    except upon the written approval of both Landlord and Tenant. The provisions
    hereof shall be in addition to any and all other obligations and liabilities
    Tenant may have to the Landlord at law or in equity and shall survive
    termination of this Lease and the satisfaction of all other obligations of
    Tenant hereunder.

D.  Right of Inspection.  Landlord, its successors and assigns shall have the
    -------------------
    right to inspect the Premises at any reasonable time and from time to time 
    upon not less than two (2) hours advance notice in order to determine
    whether Hazardous Materials are being used in violation of Environmental
    Law and whether Tenant is in full compliance with the terms of this Section,
    but Landlord shall have no obligation to conduct such inspections.  All 
    such inspections, including, without limitation, investigation, studies, 
    sampling and testing, shall be at Tenant's expense if the Premises are not
    in compliance with this Section, otherwise they shall be at Landlord's 
    expense.  Tenant is authorized to install its own security system for access
    to the Premises using so-called security card devices.  Tenant shall
    immediately release any such security system upon notice from Landlord's 
    security personnel that an emergency exists requiring access to the 
    Premises.  Inspections by Landlord under this paragraph shall not 
    unreasonably interfere with the operation of Tenant's business and Landlord
    shall comply with Tenant's Confidentiality Requirements (as defined in 
    Section 17.01 of this Lease) and Tenant's reasonable requests, provided, 
    however, these provisions are subject to any actions reasonably necessary
    to meet or ameliorate any emergency threatening serious bodily injury or
    property damage.

E.  Effect on Insurance.  Notwithstanding anything in this Section to the
    -------------------
    contrary, Tenant shall not use or occupy or permit the Premises to be
    used or occupied, nor do or permit anything to be done in or on the 
    Premises, in a manner which will in any way make void or voidable any
    insurance customary for buildings or property similar to the Premises
    (containing terms and conditions customary for insuring buildings or
    property similar to the Premises) then in force with respect thereto,
    or which will make it unreasonably difficult or impossible to obtain
    fire or other insurance (containing terms and conditions customary for
    insuring buildings or property similar to the Premises) carried by
    Landlord with respect to the property of which the Premises is a part.  If 
    Tenant's failure to comply with the provisions of this Section causes any
    insurance premium to be higher than it would otherwise be, Tenant shall
    reimburse Landlord, as additional rent, for that part of all insurance
    premiums thereafter paid by Landlord which have been changed because of
    Tenant's failure.

F.  Reports.  At reasonable intervals, and at least annually, Tenant shall
    -------
    provide to Landlord, at Landlord's request, a list of all Hazardous
    Materials at any time used, stored, placed or brought onto the Premises 
    since the date of the last report furnished to Landlord with respect to 
    Hazardous Materials.  In addition, Tenant shall provide to Landlord such
    reasonable documentation as Landlord may request to review the methods 
    and procedures used by the Tenant in handling and disposing of any Hazardous
    Materials.  If Landlord determines in its reasonable judgment that any
    Hazardous Material as it is being used by Tenant (taking into account the
    nature of the Hazardous

 
Material, the manner of its use and the quantities on the Premises) presents an
unreasonable hazard to, or unreasonably endangers the health, safety or welfare
of, the Building's Tenants, or any of them, Tenant shall, as appropriate, upon
written notice from Landlord cease using any such Hazardous Material on the
Premises and immediately dispose of such Hazardous Material in compliance with
all Environmental Law or appropriately modify its use thereof so as to not
render such use unreasonably hazardous or dangerous. In the event that Tenant
disputes Landlord's assessment or designation of any prohibited Hazardous
Material, the matter shall be referred to an Environmental Engineer for
decision. The decision of such Environmental Engineer shall be conclusive on the
parties (except the extent that such decision is overridden by any governmental

                           SECOND AMENDMENT TO LEASE

This Amendment to Lease is made the third day of October, 1994, by and between 
DOMINO'S FARMS HOLDING LIMITED PARTNERSHIP, a Michigan Corporation, having 
offices at 24 Frank Lloyd Wright Drive, Ann Arbor, Michigan 48106 ("Landlord"), 
and AASTROM BIOSCIENCES, INC. having offices at 24 Frank Lloyd Wright Drive, Ann
Arbor, Michigan 48106 ("Tenant").

WHEREAS, Landlord and Tenant entered into a Lease commencing October 1, 1992
(the "Lease") for approximately 4,592 of usable square feet of office space in
the building commonly known as Domino's Farms Prairie House; and

WHEREAS, modifications were made to the original lease on February 26, 1993 
which increased the total usable square feet to 4,783 with a corresponding 
increase in rent charge; and

WHEREAS, Tenant desired further modifications to be made to the original lease 
and subsequent First Amendment; and

WHEREAS, Landlord agreed to the modifications proposed by Tenant;

NOW, THEREFORE, in consideration of the mutual covenants contained in this 
Second Amendment to Lease, the parties agree to the following changes:

1.  Tenant expanded into the former Allstate Insurance Company suite, effective
    July 12, 1993.  Said suite is 750 square feet, and is further identified on
    the attached floor plan.  Tenant accepted space in current configuration;
    Landlord painted suite, provided an allowance of $1,200 for carpet
    replacement (to be arranged by Tenant), and provided an allowance of $806.30
    for installation of soffit lighting (to be arranged by Tenant).  No further
    contribution was made by Landlord, and no further modifications to space 
    were made by Tenant.  Based upon the necessity of relocation of Allstate 
    Insurance Company to allow for said expansion, Tenant agreed to pay a pro-
    rated share of the unamortized tenant improvement costs initially paid by
    the Landlord.  A surcharge of $228.45 will be assessed each month through
    May 1995 (initial term covered by this Lease agreement).

2.  Tenant expanded into an additional 2,115 square feet of usable space,
    located between the leased premises and the expansion space described
    in Item #1 above.  Construction of said space was complete and rent
    became effective September 20, 1993.
    
    Per the terms of the original Lease, Landlord contributed Fifty Nine
    Thousand, Two Hundred Twenty Dollars ($59,220.00) towards the construction
    costs for said expansion.  Tenant contracted for and managed construction,
    with approval of Landlord.

3.  Tenant agreed to lease a storage room located on Level 1 of the Building.
    Said room is 868 square feet, of which 728 square feet is usable by Tenant,
    and is further identified on the attached floor plan.  Tenant agrees to at
    all times maintain a five foot (5') clear aisle to doors entering building
    mechanical room east of leased storage room.  Landlord agrees to provide an
    allowance of $600 for installation of electrical power to said room.  
    Tenant, at its expense, may elect to make additional modifications to room,
    and same will be coordinated with Landlord.  Rent for said room will be
    calculated based upon 728 square feet, at a rate of $8.00 per square foot,
    and will equal $485.33 per month.

 
 4.  Based upon the changes described in Item #1 and #2 above, the total
     monthly charge for rent will now be based upon a total of 7,648 usable
     square feet, and will equal $14,856.24.  With the surcharge described in
     Item #1 above, total monthly rent due for office and lab space will equal
     $15,084.69.  Total rent due for storage space described in Item #3 above
     will equal $485.33.

 5.  The terms and conditions of the Lease shall remain in full force and
     effect except as specifically modified herein.

 IN WITNESS WHEREOF, this Second Amendment to Lease is executed on the date
 set forth above.

                           THIRD AMENDMENT TO LEASE

This Amendment to Lease is made the 16th day of November, 1994, by and
                                    ----
between DOMINO'S FARMS HOLDING LIMITED PARTNERSHIP, a Michigan Corporation,
having offices at 24 Frank Lloyd Wright Drive, Ann Arbor, Michigan 48106 
("Landlord"), and AASTROM BIOSCIENCES, INC., having offices at 24 Frank Lloyd 
Wright Drive, Ann Arbor, Michigan 48106 ("Tenant").

WHEREAS, Landlord and Tenant entered into a Lease commencing October 1, 1992
(the "Lease") for approximately 4,592 of usable square feet of office space
in the building commonly known as Domino's Farms Prairie House; and

WHEREAS, modifications were made to the original lease on February 26, 1993 
which increased the total usable square feet to 4,783 with a corresponding 
increase in rent charge (First Amendment); and further modifications were 
made to the original lease on October 3, 1994 which increased the total usable 
square feet to 7,648 and provided for rental of a storage room of 728 square
feet, with corresponding increases in rent charge (Second Amendment); and

WHEREAS, Tenant desires further modifications to be made to the original lease 
and subsequent First and Second Amendments; and

WHEREAS, Landlord agrees to the modifications proposed by Tenant;

NOW, THEREFORE, in consideration of the mutual covenants contained in this
Third Amendment to Lease, the parties agree to the following changes:

1.  Tenant will expand into 6,723 usable square feet located across the
    corridor from the existing premises, and further identified on Attachment A.

2.  Modifications will be made to the expansion suite.  Tenant will be 
    responsible for development of plans and all aspects of the construction
    process.  However, plans must be submitted to and approved by Landlord
    prior to construction start-up.

3.  $188,244 will be contributed by the Landlord to the cost of the tenant
    improvements. This sum is equal to $28.00 per square foot. Further, Landlord
    will bear responsibility for certain work, to include floor leveling (cement
    work), installation of a fire damper, relocation of an alarm panel,
    construction of the demising wall along the East wall of the expansion
    suite, and installation of a major air supply duct. Upon completion of the
    project, as-built drawings and a financial summary will be provided to
    Landlord to detail the total scope of the project. Said improvements are
    projected to be completed by November 15, 1994.

4.  On or before January 1, 1995, Tenant will vacate and be released of all
    responsibility for the 750 usable square feet acquired by Tenant on July
    12, 1993.  Said space is required by Landlord for installation of a
    mechanical room.  A corresponding reduction in rent will be applied, and
    the monthly surcharge for said space will be discontinued.

5.  For the period of November 16, 1994 through March 15, 1995, Tenant will
    pay no rent for the expansion suite.  However, during this time period,
    Tenant will pay $7.35 per square foot ($4,117.84 per month) to be applied
    to the cost of utilities, maintenance, taxes, grounds, and housekeeping
    for the expansion suite.

 
    For the period from March 16, 1995 through May 31, 1995, Tenant will pay 
    rent for the expansion suite at the same rate provided in the initial lease
    ($21.00 per square foot plus $2.31 for a utility charge).

6.  The Lease will expire on May 31, 1995, and via this Third Amendment,
    will be extended for an additional three year term (June 1, 1995 through
    May 31, 1998).  From June 1, 1995 forward, the rental rate will be
    considered a gross rate.

7.  Effective June 1, 1995, an annual increase of three percent (3%) will be
    applied to the rates for this Lease.  Said rates and rents due are detailed
    on Attachment B to this Amendment (Rent Payment Schedule).

8.  Tenant shall have a right to terminate the Lease during the three year
    extension period, in the event of any one of the following:

    a.)  Landlord is unable to provide acceptable space for further expansion
    of the Tenant; or

    b.)  AASTROM Biosciences, Inc. is acquired by another company and the
    company is relocated to a non-Michigan site; or

    c.)  Zoning or other governmental restrictions limit the Tenant from
    conducting business at Domino's Farms.

    In the event the Tenant elects to terminate the Lease based upon one of
    the stated factors, the following shall apply:

    i)    Tenant shall provide Landlord with twelve (12) month written notice
    of any intent to terminate.

    ii)   To the extent reasonable, Tenant will assist with location of a
    replacement tenant.  Subject to Section 16 of the Lease, Tenant may sub-
    lease the Premises.

    iii)  Tenant will re-pay the unamortized tenant improvements stated above
    ($188,244.00) based upon a three year amortization schedule.  Such re-
    payment of unamortized tenant improvements will be made only if Tenant is
    unable to find a sub-tenant and/or Landlord is unable to lease the premises
    essentially "as is" within ninety (90) days following the early termination
    date of Lease.

    iv)   The four month rent abatement will be re-paid if notice to terminate
    is given within the initial eighteen months of the three year lease 
    extension period.

9.  Tenant shall have a Second Right of Refusal for the approximately 7,590
    square feet located North of and contiguous to the expansion suite.
    (As of the date of this Amendment, Parke-Davis has a First Right of
    Refusal for said suite.)  Tenant shall have a First Right of Refusal for
    the approximately 5,000 square feet located North of and contiguous to the
    suite covered by the Second Right of Refusal.  Said suites are further
    identified on Attachment A.

    Under the exercise of either Right of Refusal stated above, the terms
    and conditions shall be as provided in Rider E of the Lease, with the
    exception of paragraph E(iii).  For any space previously unoccupied by a
    Tenant and in an unfinished status, an allowance in the set amount of
    $28.00 per square foot shall be provided.  For any space built out and
    occupied by another tenant, the Landlord would be responsible for any 
    negotiated
  

 
     relocation and associated costs.  An allowance to Tenant would be
     provided in the amount of $8.00 per square foot for any alterations
     resulting in office space, and $12.00 per square foot for any alterations
     resulting in laboratory space.

10.  Tenant shall have one option to extend the lease for a term up to five
     (5) years.  Tenant shall notify Landlord in writing of intent to extend
     at lease one hundred eighty days (180) prior to lease expiration.  Rent
     for such extension shall be at a rate equivalent to the rate in effect
     during the last year of the lease prior to such proposed extension, with
     an adjustment of three percent (3%) applied during the first and each
     subsequent year of the extension.

11.  The terms and conditions of the Lease shall remain in full force and
     effect except as specifically modified herein.

IN WITNESS WHEREOF, this Third Amendment to Lease is executed on the
date set forth above.

II.  FUNDING

     Aastrom shall provide payment to the Institution in accordance with the
     terms contained in the Schedule of Clinical Trial Milestone Payments
     attached as Exhibit D and incorporated herein.

III.   CONDUCT OF STUDY

     A.   Facilities
          ----------

          The Study shall be conducted only at the following location(s):  The
          University of Texas M.D. Anderson Cancer Center, 1515 Holcombe Blvd.,
          Houston, Texas 77030.  The CPS and other Study materials may not be
          transferred to any other location or to any third party without the
          prior written consent of Aastrom.

     B.   Investigator
          ------------

          The Institution agrees that the Study will be conducted under the
          direction of the Principal Investigator in accordance with the
          Protocol and the Investigator Agreement (included as Exhibit E of the
          Agreement) and incorporated herein by reference.  The Principal
          Investigator may, subject to the prior written consent of Aastrom,
          designate a clinical coordinator and one or more subinvestigators to
          assist in conducting the Study.  The Institution acknowledges that the
          Principal Investigator and subinvestigators have each executed an
          Investigator Agreement, copies of which are included in Exhibit E.  In
          the event that additional subinvestigators are added to the Study,
          such subinvestigators must execute and deliver an Investigator
          Agreement which shall be deemed incorporated by reference into this
          Agreement. In the event the Principal Investigator can no longer
          function in such capacity, then Aastrom and the Institution shall
          attempt to agree on a replacement.  If a mutually acceptable
          replacement cannot be agreed upon, this Agreement and the Study at the
          Institution shall terminate.  The Institution agrees that it will use
          its best efforts to recruit qualified subjects for enrollment in the
          Study consistent with the guidelines contained in the Protocol and the
          best interest of the subjects; however, no subjects shall be enrolled
          in the Study if they are currently enrolled in another investigational
          study without the prior written consent of Aastrom.

     C.   Compliance with Protocol
          ------------------------

          Any changes to the Protocol may only be made with the prior written
          agreement of Aastrom; provided that during the Study, if the Principal
          Investigator feels that it is necessary to deviate from the Protocol
          in order to protect the life or physical well-being of a Study subject
          before written approval can be obtained, he/she may do so in
          accordance with the procedures detailed in the Protocol.

                                       2

          Institutional Review Board ("IRB") prior to initiating the Study and
          thereafter as required by applicable laws, rules and regulations; and
          (ii) prior written informed consent of all subjects and/or their legal
          guardians in a form that is substantially the same as provided in the
          Protocol and satisfactory to both the governing IRB and Aastrom and in
          compliance with applicable laws, rules and regulations.

     E.   Adverse Events

          The Institution shall immediately notify Aastrom (Dr. Thomas E. Muller
          at 313/930-5555 and/or by fax at 313/665-0485) of any unanticipated
          adverse effect, whether ascribed to the investigational device or not,
          in accordance with instructions provided in the Protocol.

IV.  STUDY MONITORING AND ACCESS TO FACILITIES

     Aastrom's designated representatives and/or authorized representatives of
     regulatory agencies may, at all reasonable times, visit the Institution in
     order to: (i) determine the adequacy of the facilities; (ii) validate case
     reports against original data in the subject medical records and the files
     of the Principal Investigator; and (iii) monitor the conduct of the Study
     to determine whether the Study is being conducted in compliance with the
     Protocol and all applicable laws, rules and regulations.  The Institution
     agrees to obtain any required subject release(s) to allow Aastrom's
     designated representatives, and/or authorized representatives of regulatory
     agencies, to conduct such review prior to enrolling each subject in the
     Study.

V.   REPORTS

          its own purposes.  Title to the CPS and Study materials shall remain
          with Aastrom.  Further, the Institution agrees that data and materials
          derived as a direct result of the Study described in the Protocol
          (hereinafter referred to as "Clinical Trial Information") whether
          generated by the 

                                       3

 
          Institution, the Principal Investigator, and/or their agents or
          employees, either solely or jointly with others, is the property of

     ------------------------------------

     The Institution agrees that the Study results and any inventions or
     discoveries by the Institution, the Principal Investigator or their agents
     or employees during the Study that are modifications, improvements or new
     uses applicable to the CPS or that are a direct result of the performance
     of the Study in accordance with the detailed testing Protocol provided by
     Aastrom to Institution and which are dependent on, or relate to, the Study,
     the claims of Aastrom's patentable inventions, the use of the cells
     processed through the CPS or Aastrom's Confidential Information shall be
     the property of Aastrom.  Any invention arising out of the work performed
     under this Study solely by the Institution and not covered in the previous
     sentence shall be the exclusive property of the Institution (the
     "Institution Invention") and shall not be considered a part of Aastrom's
     Confidential Information.  The Institution shall promptly disclose each
     such Institution Invention and the terms under which the Institution would
     be prepared to license it.  Aastrom shall have a right of first refusal to
     exclusively develop, license and commercialize such Institution Invention.
     Aastrom shall have sixty (60) days after receipt of such disclosure to
     exercise its right of first refusal, and if so exercised, the parties shall
     thereafter negotiate a mutually acceptable licensing agreement in good
     faith.  If the Institution at any time offers such Institution Invention on
     terms different than those disclosed to Aastrom, the Institution shall
     offer such Institution Invention to Aastrom on such different terms in

          information which the Institution can demonstrate:
 
          i.   Was known to the Institution prior to receipt from Aastrom,
               provided that the Institution promptly notifies Aastrom in
               writing of the same promptly after disclosure by Aastrom;

          ii.  Is or becomes part of the public domain through no act by or on
               behalf of the Institution;

          iii. Was lawfully received by the Institution or the Principal
               Investigator from a third party who had a legal right to disclose
               the same; or

          iv.  Is required by law or regulation to be disclosed.

          In the event that Confidential Information is required to be disclosed
          pursuant to subsection iv., the Institution will notify Aastrom to
          allow Aastrom to assert whatever exclusions or exemptions may be
          available to it under such law or regulation.

          ---------

          No publicity, news releases, or other public announcement, written or
          oral, relating to the Agreement, to any amendment hereto or to
          performance hereunder or to the existence of an arrangement between
          the parties, shall be originated by either party without the prior
          written approval, such approval not to be unreasonably withheld, of
          the other party except as shall be required by law.

     C.   Use of Name
          -----------

          No Party shall use or publicly disclose the name of another party
          hereto without the prior written consent, such consent not to be
          unreasonably withheld, of such other party except that the name of a
          party may be disclosed to regulatory bodies such as the FDA,
          Securities and Exchange Commission or as required by law.

XII. PUBLICATION RIGHTS

     At least thirty (30) days prior to submission for publication, the
     Institution agrees to provide Aastrom a final draft of any manuscript
     describing the results obtained by the Institution from 

                                       7

 
         the Study. Aastrom shall be permitted to advise as to the implications
         of such manuscripts upon patentability of any inventions or the
         potential effects on commercialization. The Institution shall, upon
         Aastrom's request, delete any of Aastrom's Confidential Information and
         shall consider all reasonable editorial suggestions based on sound
         scientific and clinical judgment, Aastrom acknowledges that Institution
         shall have the final authority to determine the scope and content of
         any publication, provided that such authority shall be exercised with
         reasonable regard for the commercial interests of Aastrom. Subject to
         Aastrom's right to delete such Confidential Information and to propose
         mutually agreeable modification of such manuscripts, the Institution
         shall have the right to submit the manuscript for publication. However,
         if Aastrom determines that any invention disclosed therein is
         patentable and that a patent application should be filed on such
         invention, Aastrom shall so notify the Institution in writing and the
         Institution shall postpone publication for a period not to exceed sixty
         (60) days from said notice (unless otherwise mutually agreed in
         writing) to provide time for patent applications to be filed.

Protocol:

FEASIBILITY STUDY OF EXPANDED PROGENITOR CELLS FOR HEMATOPOIETIC ENGRAFTMENT IN 
PATIENTS WITH BREAST CANCER

Study Chairman:  Richard Champlin, M.D.

OBJECTIVES:

Assess the safety of the mixture of early- mid- and late stage bone marrow 
derived mononuclear cells produced in the Cell Production System (CPS) (primary 
objective and the biologic effect on hematopoietic recovery after infusion of ex
vivo expanded hematopoietic cells following high dose chemotherapy as treatment 
of patients with breast cancer.

RATIONALE:

High dose chemotherapy is increasingly used for treatment of malignancies.  
Despite infusion of autologous bone marrow or PBPC, patients experience at least
one week of profound pancytopenia prior to engraftment and hematologic recovery.
Recently technology for expansion of hematopoietic progenitors ex vivo has been 
developed and we performed a study showing no toxicity and rapid hematopoietic 
recovery when given in addition to autologous bone marrow.  The expansion 
systems produces large numbers of progenitors similar to that present in full 
autologous marrow graft and the expansion conditions do not support the growth 
of malignant cells, thus the system acts to purge contaminating tumor cells from
the autologous graft.  Preliminary studies suggest that infusion of large 
numbers of expanded cells may modify the nadir of granulocytopenia and 
potentially reduce infectious complications.  Recently, Brugger et al reported 
rapid engraftment and hematopoetic recovery using ex vivo expanded cells alone. 
This study is designed to assess hematopoietic recovery after high dose 
chemotherapy and infusion of cells expanded using the Aastrom expansion device.

1.0  OBJECTIVE

     Assess the safety of the mixture of early-, mid-, and late-stage bone
     marrow-derived mononuclear cells produced in the CPS (primary objective),
     and the biological effect in terms of hematopoietic recovery after infusion
     of ex vivo-produced hematopoietic cells following high dose chemotheraphy
     as treatment of patients with breast cancer.

2.0  BACKGROUND

     Autologous bone marrow transplantation has been increasingly employed as
     supportive therapy for subjects undergoing high dose chemotheraphy or
     chemoradiotherapy for malignant diseases, including lymphoma, leukemia, and
     breast cancer. Breast cancer is now the most frequent indication for
     autologous bone marrow or blood progenitor cell transplantation.

     Despite the use of cytokines such as granulocyte-macrophage colony-
     stimulating factor (GM-CSF) and granulocyte colony-stimulating factor (G-
     CSF) following bone marrow reinfusion, there is an obligate period of
     profound pancytopenia lasting 1-3 weeks, and delayed engraftment can occur,
     resulting in morbidity or mortality.

     The safety, comfort, and cost of stem- and progenitor cell harvest are also
     concerns. The standard techniques employed to harvest bone marrow involves
     obtaining 500-1500 mL of bone marrow from the marrow donor, usually under
     general anesthesia. In addition to the discomfort caused by the hundreds of
     marrow aspirates performed, donors are subject to the risks of general
     anesthesia. Finally, the bone marrow harvest procedure is expensive.
     Alternatively, stem - and progenitor cells can be collected from peripheral
     blood by apheresis, but this requires chemotherapy and/or growth factors
     for mobilization and multiple collections are generally necessary, which
     are costly.

     Recently, novel technology has been developed to produce stem- and
     progenitor cell populations in vitro, commonly referred to as ex vivo
     expansion. Hematopoietic cell expansions achieved with this technology are
     based upon the principles of continuous perfusion culture, a bioengineered
     metabolic environment, augmented by hematopoietic growth factors. Through
     this technology, a small bone marrow or peripheral blood mononuclear cell
     population can be perfused ex vivo so that total cell numbers, colony
     forming units (CFUs) and long term culture initiating cells (LTC-ICs)
     increase up to 20 fold (1-17). In a preliminary study, Brugger et al
                                                                    -----
     recently reported that expanded cells alone can reconstitute hematopoiesis
     after high dose chemotheraphy (18).

     Important differences exist among approaches, systems and devices used for
     ex vivo expansion. This study utilizes the Aastrom CPS, which includes a
     cell


 
culture device and a biological environment designed to allow the establishment
of a stromal adherant layer, using constant perfusion with medium, and
relatively low concentrations of hematopoietic growth factors. Preliminary
studies at MD Anderson Cancer Center (DM94-127), using transplantation of ex
vivo-produced cells prepared with this system, in combination with a standard
autologous marrow transplant, indicate that ex vivo expansion can be performed
reliably and reproducibly, and that no toxicity occurs with intravenous infusion
(19). Ten patients, age 18-60 years with breast carcinoma, were entered into a
study transplanting bone marrow plus ex vivo-produced cells. Bone marrow was
harvested, collecting greater than 2 x 10/8/ nucleated cells/kg and greater than
0.5 x 10/6/ CD34+ cells/kg. Twelve days prior to the planned bone marrow
transplant, 2.25 x 10/8/ mononuclear cells were inoculated into a cell culture
device, part of the CPS, and continuously perfused with medium containing
PIXY321 (5 ng/ml), Epo (0.1 U/ml) and hydrocortisone (5 x 10-6/ M). The
expansion reproducibly increased total nucleated cells, CFU-GM, and long term
culture initiating cells (LTC-IC). Patients received Cyclophosphamide 
2.0 g/m/2/d; Thiotepa 240 mg/m/2/d; BCNU 150 mg/m/2/d, Days -7, -6, -5, with
reinfusion of the cryopreserved bone marrow on Day 0 plus the ex vivo-produced
cells four hours later. No toxicity was observed from the expanded cell
infusion. Nadir WBC was less than 0.1/ul. All patients engrafted within narrow
time ranges, with median recovery of WBC greater than 200/ul on Day 8 (range 7-
8) granulocytes greater than 500/ul on Day 11 (range 10-13) and platelets
greater than 25,000/ul on Day 16 (range 13-21) and greater than 50,000 on Day 20
(range 18-27). A median of 4 (range 1-9) platelet and 4 (range 2-9) RBC
transfusions were administered. No grade greater than 2 toxicity occurred from
the chemotherapy or bone marrow infusions. Four patients had infections
unrelated to the infusion of the cells produced in the CPS. These data compare
favorably with 29 historical controls receiving the same chemotherapy and
autoBMT without cell expansion, in which granulocytes recovered to greater than
500 on Day 11 (range 7-29) and platelets to greater than 25,000 and greater than
50,000 on Days 24 (range 9-78) and 28 (range 9-147), respectively.

A potential advantage of collecting a relatively small marrow inoculum is that 
the number of contaminating malignant cells is reduced; additionally, growth of
breast cancer cells is not stimulated under these expansion conditions (Brugger 
et al).

Application of this technology to autologous bone marrow and peripheral stem
cell transplant offers a potentially attractive means to increase the efficacy
and safety of autologous transplantation, while reducing its complexity and
cost. In particular, this technology could eliminate the need for operative bone
marrow harvests, produce more rapid recovery of hematopoiesis post-transplant,
reduce the length of post-transplant hospitalization, and could increase the
purity of the stem- and progenitor cells transfused. In addition, the inclusion
of cytokine-primed progenitors could result in accelerated hematopoietic
recoveries.

 

        2.1  PREVIOUS PRE-CLINICAL RESEARCH
        
During hematopoietic expansion culture, total cell numbers increase 8 to 11-fold
over 12 days. This includes nonadherent, loosely adherent, and tightly adherent
cells. Over 80% of the nucleated cells are viable, as shown by exclusion of
propidium iodine stain (4) or Trypan blue dye. These cells have the
morphological distribution of normal bone marrow cells, including blast cells
and maturing granulocyte precursors, maturing erythroid cells, monocytes and
macrophages.

These expanded cells also show typical immunophenotype characteristics of normal
granulocyte, erythroid, monocyte/macrophage megakaryocytic, and blast cells (5).
Cell surface antigens identified using this technique include CD3, CD11b, 
CD15, CD20, CD33, CD71, and glycophorin A.  While there are minor variations in 
staining patterns from sample to sample, the expanded cells are typically less 
than 3% CD3+, 20-50% CD11b+, less than 1% CD19+, and 40-70% CD71+.  The 
frequency of mature T and B lymphocytes in the expanded cell population is 
significantly reduced.

As shown in the experiments summarized in the Table below, it was shown by 
Aastrom that varying the standard growth factor combination (IL-3+GM-CSF or 
PIXY321, Epo, SCF and flt3L) had a direct effect on the productivity of cells in
the CPS, but the relative cell mixture composition remained substantially 
similar.  These data were obtained in 36-well plate studies.  This finding 
provided the original justification for selecting the growth factor combination 
(Epo + PIXY321 + flt3L) for this study to yield the desired relative composition
and mixture of early-, mid- and late-stage cells produced in the pre-clinical 
experiments.

/a/LTC-IC were not evaluated, but in these conditions, 24 week CFU-GM producing cultures were obtained, representing an LTC-IC proxy. Aastrom has projected, based on this pre-clinical research, that clinical-size CPSs are expected to yield a mean of 3.0 x 10/9/ cells, 17.7 x 10/6/ CFU-GM and 6.4 x 10/5/ LTC-IC per patient cell yield from the CPS at 1.6 x 10/9/ total nucleated cells and 7.0 x 10/6 CFU-GM. In an average 70 kg patient, this translates to a dose of 2 x 10/6/ CFU-GM/kg. The clinically standard ABMT engrafting dose is reported to be 1 x 10/5/ CFU-GM/kg. Therefore, using the cell dose and the CFU-GM content in the cells produced in the CPS as a key progenitor marker, along with the reliable presence of early stage cells (e.g., LTC-IC, CD34+lin-), there is an expectation that the CPS-produced cells should provide a minimum full engrafting dose for these subjects, with a greater number expected for most patients. Should the minimum cell number, 1.6 x 10/9/, not be attained, the cryopreserved back-up cells will be reconstituted and administered to a subject on Day 0. It is anticipated that infusion of ex vivo-produced progentiors generated with the CPS will enhance engraftment and shorten time to recovery of granulocytes and platelets and, in so doing, reduce the incidence of infections, febrile episodes and the need for blood- and platelet transfusions. 2.2 HIGH DOSE CHEMOTHERAPY AND AUTOLOGOUS BONE MARROW TRANSPLANT FOR METASTATIC BREAST CANCER - MD ANDERSON PROGRAM Breast cancer is responsive to initial combination chemotherapy for metastatic disease with a 50-80% response rate and a 10-20% complete response rate, but few patients are cured and median duration of response is generally less than one year (20-24). Once patients relapse, the response to second-line therapy is 20-40% with very few complete responses (CR) and a median duration of response of 2-3 months and a median survival of 12 months. When patients with metastatic breast cancer receive high-dose chemotherapy, there is substantially higher complete response rate than that can be achieved with conventional treatment (25-38). Peters el al (39) used a regimen of Cyclophosphamide, Cisplatin, and BCNU or Melphalan in 22 ER-negative patients without prior induction chemotherapy, and reported a 54% CR rate and an overall response rate of 73% and a median duration of response of 7 months from the time of transplant. Antman et al recently reported similar results with a ----- combination of high-dose Carboplatin, Cyclophosphamide and Thiotepa (26); each study reported approximately 20% 5-year disease-free survival. Application of the same therapy to patients with Stage II breast cancer with greater than or equal to 10 positive nodes or Stage III disease has resulted in approximately 70% 5-year disease-free survival, substantially higher than that reported with standard adjuvant therapy in such patients. Studies from a number of drug-resistant cell lines suggest that different alkylating agents may not be cross-resistant, particularly if they interact with DNA at different sites, or if the alkylating agent previously used may have specific mechanisms of resistance (such as exaggerated levels of aldehyde dehydrogenase) in tumor cells resistant to Cyclophosphamide. Cyclophosphamide and Thiotepa have been shown to have synergistic activity against human breast cancer in preclinical models (40). These two agents have been used together in high dose therapy with the reported MTD being 6g/m/2/ of Cyclophosphamide with 720 mg/m/2/ of Thiotepa, with severe mucositis being the dose-limiting toxicity if one attempts to increase Thiotepa dose further (41,42). None of the 17 patients treated with 6000 mg/m/2/ of Cyclophosphamide and Thiotepa, in doses ranging from 180 to 720 mg/m/2/ developed mucositis. Mild oral pain and erythema developed in 2/3 patients treated at the 720 mg/m/2/ level of Thiotepa, and at 900 mg/m/2/ 3/3 had severe life-threatening but reversible oral and esophageal mucositis. Cyclophosphamide, BCNU, and Cisplatin has been a commonly used preparative regimen at other centers for ABMT for breast cancer (33). In other studies with high dose BCNU, pulmonary complications can be avoided by lowering the dose of BCNU to 450 mg/m/2/, including the CBT regimen described below. Phase I studies of the combination of Cyclophosphamide, BCNU, and Thiotepa with autologous bone marrow transplantation in high risk patients with metastatic breast cancer (DM91-031, DM92-060 and DM92-084) were recently evaluated. The maximum tolerated dose was Cyclophosphamide 6 gm/m/2/, BCNU 450 mg/m/2/ and Thiotepa 720 mg/m/2/. The regimen produces marked myelosuppression, but with prompt recovery using autologous bone marrow transplantation. Reponse rates and survival with autologous bone marrow transplantation are highly dependent on patient prognostic characteristics, such as prior disease-free interval, sites and number of metastasis, and response to prior chemotherapy. This regimen has proven to be highly active. Among patients with a partial response to chemotherapy, 52% achieved a complete response with this regimen; results were from comparable to superior to other high dose programs. 3.0 BACKGROUND DRUG AND DEVICE INFORMATION 3.1 DESCRIPTION OF THE CPS The single-use, sealed, sterile cell culture device in the Aastrom CPS consists of three rigid plastic parts separated by a gas-permeable, water- impermeable membrane. The lower cell culture chamber is continuously perfused by growth medium. The cells expand in culture on the plastic surface of the cell culture bed. The upper cell culture chamber is provided with a constant flow of gas, such that oxygenation of the cell culture bed is accomplished by diffusion across the membrane and through the culture medium. Carbon dioxide is removed by the same mechanism. The medium used to perfuse the cultured cells is stored in a closed vessel in an adjacent refrigerator at 4 degrees C whose only external connection is by medical grade tubing. A "Y" connector, attached to the effluent line, allows sampling of the cell product prior to harvest, to test for bacterial and fungal contaminants. A detailed device description is provided in the Operator's Manual provided by Aastrom. 3.1.1 CELL CULTURE CONDITIONS The hematopoietic cells are suspended in tissue culture medium composed of Iscove's Modified Dulbecco's Media supplemented with 10% fetal bovine serum, 10% horse serum, hydrocortisone (5 x 10/-6/M), PIXY321 (5 ng/ml), glutamine (4 mM), Erythropoietin (Epo 0.1 U/ml), flt3L (5 ng/ml), gentamicin sulfate (5 Fg/ml), vancomycin (20 Fg/ml), sterile water for injection, and are inoculated into the CPS. The cells are cultured in the CPS for 12 days at 37 degrees C with the tissue culture medium continuously replaced with fresh medium. Sampling of the culture medium is carried out 48 hours prior to harvest, to allow testing for bacterial and fungal contaminants. To harvest the cells, the non-adherent fraction is removed from the cell culture device by draining the growth medium from the cell culture device into the harvest bag. The chamber is then rinsed with 50 ml of Hank's Balanced Salt solution (HBSS) by injection of the solution with a syringe via an access port. This is followed by agitation of the cell culture device and collection of the rinse into the harvest bag. The adherent layer is detached from the cell culture bed surface by injection of 50 ml of Trypsin-EDTA solution by syringe via an access port. This is also followed by agitation of the cell production device and collection of the rinse into the harvest bag. The chamber is then given a final rinse by injecting 50 ml of HBSS with a syringe via an access port. This is followed by agitation of the cell production device and collection of the rinse into the harvest bag. Following collection, the cells are washed free of culture medium as detailed in the Operator's Manual. The final product is suspended in appropriate media for immediate infusion. 3.1.2 CELL CULTURE MEDIA INFORMATION Studies by Aastrom and the University of Michigan have shown that, after the cell washing regimen, the added growth factors and other reagents are below detectable limits, using a very sensitive ELISA assay (R&D Systems, Minneapolis, MN, and Immunex Research Corporation, Seattle, WA). These levels are well below the level of biological activity. The horse and fetal calf sera are tested preclinically for contamination for bacteria, fungi, mycoplasma, endotoxin and viruses. The expanded cell product is washed (See Operator's Manual) prior to transfusion. Nonetheless, the human toxicities and contraindications identified for these drugs are included below: 3.1.2.1 RECOMBINANT HUMAN EPO Recombinant Human Erythropoietin: Epoetin Alfa, Procrit, NDC 0062-7402-01 Amgen, Thousand Oaks, CA. Human Toxicity: Toxicities have included hypertension, headache, fever, seizures, and skin rash. The majority of these subjects had chronic renal failure, and these adverse events are frequent sequelae of chronic renal failure and were not necessarily attributable to Epo. Contraindications: Epo is contraindicated in subjects with: uncontrolled hypertension, known hypersensitivity to mammalian-derived products, and known sensitivity to human albumin. 3.1.2.2 PIXY321 PIXY321 is a fusion protein of granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin 3 (IL-3). 3.1.2.3 RECOMBINANT GM-CSF Human Toxicity: Specific toxicities include peripheral edema, pleural and/or pericardial effusions, fluid retention, sequestration of granulocytes in the lung, supraventricular arrhythmia, elevation of serum creatinine, and elevation of hepatic enzymes. Contraindications: GM-CSF is contraindicated in subjects with excessive leukemic blasts in the bone marrow or peripheral blood (greater than 10%), or with known hypersensitivity to GM-CSF, yeast-derived products, or any component of the product. 3.1.2.4 FLT3 LIGAND (FLT3L) The manufacturer of flt3L, Immunex Research and Development Corporation, Seattle, WA, has advised that a biologic Master File is in preparation for clinical, in vivo grade flt3L, and that the Master File will be submitted to the FDA in 1996, and will be available as reference for the purposes of this clinical feasibility trial (Letter, Immunex to Aastrom, December 11, 1995). Immunex has also advised that flt3L appeared to be well tolerated when administered to mice and monkeys for 14 days, at doses up to 400 ug/kg/day. Based on the safety profile established by Immunex, including the animal data generated to-date, flt3L has no apparent toxicities, and does not stimulate the proliferation and detrimental activation of mast cells. As indicated above, the cells produced in the CPS are washed four times, resulting in a 5-log reduction in the presence of media components, to levels below detectable limits. An ELISA, supplied by Immunex, is used to determine residual flt3L levels subsequent to cell washing. 3.1.2.5 HORSE SERUM Contraindications: Known hypersensitivity to horse serum. 3.1.2.6 FETAL CALF SERUM Contraindications: Known hypersensitivity to bovine serum. 3.1.3 INTENDED USE The intended use of the CPS is to produce human stem- and hematopoietic progenitor cells to support subjects with compromised hematopoietic systems. A per-patient cell production procedure, beginning with 225 x 10/6/ nucleated bone marrow cells per device, will yield at least 1.6 x 10/9/ cells. The cells will not be infused if the cell yield is below this level; the back-up cells will be infused in such a case. 3.2 CHEMOTHERAPY DRUG INFORMATION CYCLOPHOSPHAMIDE NSC# 26271 Synonyms (Trade names, etc.): Cytoxan, Endoxan Therapeutic Classification: Alkylating agent Pharmaceutical Data: Oral tablets of 25 mg and 50 mg; powder for ------------------- injection in vials of 100 mg, 200 mg, and 500 mg. Solution Preparation: Add 5 ml sterile water for injection or normal -------------------- saline for injection to 100 mg vial, 10 ml to 200 mg vial, and 25 ml to 500 mg vial. The resulting concentrations will be 20 mg/ml. For infusion, dilute further with 100-250 ml of D5W or NS and infuse over 15-60 minutes. Stability and Storage Requirements: ---------------------------------- Prior to mixing: Room temperature After mixing: Stable for 24 hours at room temperature and 6 days if refrigerated. Routes of Administration: Oral, IV Push, IV infusion ------------------------ Usual Dosage Range: Up to 2000 mg/m/2/ as a single dose, repeated every 3 ------------------ weeks. Smaller doses may be given more frequently. Doses of up to 1.5 gm/m/2/d x 4 may be used in conjunction with bone marrow transplant. Known Side Effects and Toxicities: Myelopsuppression (leukopenia greater than - --------------------------------- thrombocytopenia), hemorrhagic cystitis, nausea, vomiting, alopecia, and rare amenorrhea and azoospermia. Special Precautions: Adequate hydration with 2-3 liters of fluid daily with - ------------------- copious urine output can prevent cystitis. Due to significant renal excretion, dose reductions must be made in patients with renal insufficiency. Status: Commercially available - ------ Mechanism of Action: Cyclophosphamide is considered a classical bifunctional - ------------------- alkylating agent, with the predominant alkylation reaction occurring at the 7 nitrogen of guanine. Cyclophosphamide must be activated by liver microsomal enzymes in order to damage the DNA molecule. Although active throughout the cell cycle, the agent is most active during the S phase. Animal Tumor Data: Cyclophosphamide exerts its greatest activity against the - ----------------- Walker 256 carcinoma, Yoshida ascitic and solid sarcomas, DS-Carcinosarcoma, and Jensen sarcoma. Activity is also noted against the leukemia L1210, adenocarcinoma 755 and sarcoma 189 tumors. Animal Toxicity: Hypoplastic changes in the bone marrow have been noted. Other - --------------- pathologic findings include hemorrhagic areas in the gastrointestinal tract, bladder, and lungs. Leukopenia was observed to a greater degree than thrombocytopenia. Human Pharmacology: Cyclophosphamide can be given orally or intravenously, - ------------------ although oral absorption is incomplete (30-60% of a dose is recoverable in the stool). Maximum plasma levels are achieved within one hour from an oral dose. Plasma T-1/2 is 4-6.5 hours. Approximately 60% of an intravenous dose is recovered in the urine within 24 hours, requiring dosage adjustments in patients with renal insufficiency. The drug is activated and subsequently deactivated by liver microsomal enzymes. References: - ---------- Bagley, C., et al.: Clinical pharmacology of cyclophosphamide.

Rev. 2:295-322, 1975. ------------------ THIOTEPA Chemistry: Thiotepa, an ethylenimine derivative, is a polyfunctional - --------- alkylating agent. The drug occurs as fine, white, crystalline flakes having a faint odor and is freely soluble in water and in alcohol. The commercially available powder for injection contains 80 mg of sodium chloride and 50 mg of sodium bicarbonate so that, following reconstitution with sterile water for injection, solutions of the drug are isotonic. Reconstituted Thiotepa solutions containing 10 mg/mL in sterile water for injection may be clear to slightly opaque and have a pH of 7.6. Stability: Both Thiotepa powder for injection and reconstituted solutions of the - --------- drug should be stored at 2-8 degree C, protected from light. Reconstituted Thiotepa solutions containing 10 mg/mL in sterile water for injection are stable for at least 5 days at 2-8 degree C; however, since the solutions do not contain a preservative, the possibility of microbiologic contamination must be considered. Solutions which are grossly opaque or contain a precipitate should not be used. Although Thiotepa is reportedly unstable in acid media, the manufacturer states that reconstituted solutions of the drug may be diluted with sodium chloride, dextrose, dextrose and sodium chloride, Ringer's, or lactated Ringer's injection. The manufacturer also states that Thiotepa solutions containing 0.5 mg/mL in Ringer's injection are stable for at least 15 days at room temperature or 2-8 degree C. Reconstituted solutions of Thiotepa are compatible with 2% procaine hydrochloride injection and/or 0.1% (1:1000) epinephrine hydrochloride injection. Pharmacology: Thiotepa, as an alkylating agent, interferes with DNA replication - ------------ and transcription of RNA, and ultimately results in the disruption of nucleic acid function. Thiotepa also possesses some immunosuppressive activity. Following intracavitary administration, thiotepa may control malignant effusions by a direct anti-neoplastic effect. Pharmacokinetics: - ---------------- Absorption: Thiotepa is incompletely absorbed from the GI tract. Variable absorption also occurs through serous membranes, such as the pleura and bladder, and from IV injection sites. Absorption through the bladder mucosa may range from 10% to almost 100% of the instilled dose and is enhanced by extensive tumor infiltration or acute mucosal inflammation, following endoscopic surgical procedures or radiation therapy, and in the presence of vesicoureteral reflux. Following IV administration of Thiotepa C14, serum concentrations of radioactivity reportedly begin to decline within 10 minutes, but detectable concentrations persist 72 hours. Distribution: It is not known if thiotepa or its metabolites are distributed into milk. Preparations: Parenteral, for injection, 15 mg. Carmustine Synonyms: BCNU, BICNU Therapeutic Classification: Nitrosourea Pharmaceutical Data: Each vial contains 100 mg of carmustine. Each ------------------- vial is packaged with sterile diluent of 3.5 ml of absolute alcohol USP. Solution Preparation: Dissolve carmustine first with 3 ml of alcohol -------------------- diluent. Then add 17 ml water for injection. This results in a solution concentration of 5 mg/ml with pH 5.0-6.0. Stability and Storage Requirements: Before mixing: Store unopened ---------------------------------- vials in refrigerator. Vials may be stored at room temperature for 1 month without significant loss of potency. Drug melts and decomposes at temperatures above 27 degrees C or 80 degrees F. After mixing: After diluted for infusion, solutions are stable for 24 hours if protected from light under refrigeration and 2 hours at room temperature without light protection. Route of Administration: I.V. infusion only. ----------------------- Usual Dosage Range: 30-300mg/m/2/ per course. Upper dose range for ------------------ use as single agent, dosage lower in combination with other agents. Courses usually repeated every 6-8 weeks, or dose may be given in divided portions at 3-4 week intervals. Courses should not be repeated until recovery from toxicities of previous course is adequate. Known Side Effects and Toxicities: The most consistent toxicities --------------------------------- involve the bone marrow, lymphoid tissue, kidneys, lungs, liver and GI tract. Rapid I.V. infusion is associated with intense flushing of the skin and suffusion of the conjunctiva within 2 hours. Nausea and vomiting appear within 2 hours and generally last 4 to 6 hours. Burning at the site of infusion is common. Suppression of the peripheral blood leukocytes and platelet counts is the most severe toxic manifestation and the major dose-limiting factor. Toxicity occurs 3-4 weeks after drug administration and lasts for 2-3 weeks. Elevated SGOT, alkaline phosphatase and bilirubin can occur 28 to 38 days after treatment but is reversible. Renal toxicity as measured by unexplained elevations of BUN was present in 10% of patients but was not related to time, dose, or schedule of the drug. Pulmonary fibrosis has also been reported with long-term therapy. The associated mortality rate is high. The reaction presents either as an insidious cough and dyspnea or sudden onset of respiratory failure. Also risk of developing second malignancies (leukemia) with use of nitrosoureas. Special Precautions: Avoid contact with skin as it might cause known ------------------- staining. Status: Commercially available. ------ Mechanism of Action: The mechanism of action of nitrosoureas is ------------------- assumed to be due to DNA cross linking. Carmustine is an S phase non- specific drug and inhibits DNA, and to a lesser extent, RNA synthesis. Alkylation reactions account for the major effect but it is also thought that carbamylation reactions may contribute significantly to their cytotoxicity. Rapid improvement in drug-resistant terminal Hodgkin's disease indicates its lack of cross-resistance to standard alkylating agents and vinca alkaloids, further suggesting a mode of action different than alkylation alone. It is thought that the intact molecule may not be responsible for activity, but rather may be due to one or more degradation products. Furthermore, the active agent for tumor cell killing may be different from the agent responsible for delayed bone marrow toxicity. In addition, it is known that carmustine interferes selectively with the utilization of histidine. References: ---------- Carmustine Drug Monograph. American Hospital Formulary Service. 4.0 PATIENT ELIGIBILITY Female patients, age 18-65 years with diagnosis of Stage IV breast carcinoma, who have received no more than one chemotherapy regimen for metastatic disease, with chemotherapy responsive or stable disease at the time of study entry. Zubrod performance status 0 or 1. Patients must be HIV negative and have creatinine less than or equal to 1.5 mg/dl; SGOT, SGPT, & bilirubin less than 2x normal, normal cardiac ejection fraction and DLCO greater than 50% of predicted. Prior to marrow collection for ex vivo expansion, patients must have WBC greater than 3,000/mm/3/ and platelet count greater than 100,000/mm/3/. Women of childbearing potential must have a negative pregnancy test within 3 weeks of study entry. Exclusion Criteria include: History of hypersensitivity to horse serum or fetal calf serum; central nervous system (CNS) disease within 6 months of study entry; Concurrent involvement in any other clinical trial that affects engraftment (e.g. other hematopoietic growth factors); treatment with any growth factors within one week; Previous pelvic radiotherapy rendering the marrow hypocellular; Previous treatment with Mitomycin-C or Carmustine (BCNU); any co-morbid condition which, in the view of the Principal Investigator, renders the patient at high risk from treatment complications; any evidence of bone marrow involvement with tumor as demonstrated by standard histopathological examination of bilateral lilac marrow biopsies within 4 weeks of study entry. 5.0 TREATMENT PLAN 5.1 Registration All patients must be registered with the Data Management office at 713-792-2926 for entry on study. 5.2 Bone Marrow Harvest Patients will undergo back-up bone marrow harvest at any time prior to initiation of the ablative chemotherapy, with cryopreservation, using standard techniques. Patients must have greater than 2 x 10/8/ nucleated cells per kg harvested, including greater than 0.5 x 10/6/ CD34+ cells/kg. The bone marrow harvest will be performed by standard technique in an operating suite under general or epidural anesthesia. In a standard harvest, approximately 500-1500 ml of marrow is withdrawn. Patients will have the back-up bone marrow collected simultaneously with the cells for ex vivo production. If a sufficient number of cells are collected, the bone marrow collected will be processed and a small fraction utilized for the ex vivo culture described below, and the remainder of the cells will be cryopreserved per standard technique and held as a back-up for use if the prescribed number of cells is not produced or if graft failure occurs. 5.3 Ex Vivo Cell Production As mentioned in other parts of the Protocol, at the time of bone marrow harvest, all harvested marrow will be delivered to the bone marrow laboratory for processing. A portion of the harvested marrow will be used for cell production in the CPS and the balance of the harvested marrow will be cryopreserved. Twelve days prior to the scheduled bone marrow transplant, 2.5 x 10/8/ mononuclear cells from freshly collected marrow will be placed into the CPS in the presence of PIXY321 (5 ng/ml), hydrocortisone (final concentration 5 x 10/-6/ M), glutamine (4mM), gentamicin sulfate (5 Fg/ml), vancomycin (20 Fg/ml), Epo (0.1 U/ml/day) and flt3L (5 ng/ml). The tissue culture medium will be supplemented with 10% fetal calf serum and 10% horse serum. A sample of the harvested marrow will be sent for bacterial/fungal culture. The cell production will be performed in the Aastrom CPS, which is operated in standard, validated laboratory equipment (incubators, refrigerators, gas pumps) which provide for constant temperature (37 degree C), pH (7.2-7.4), and delivery of sterile air (5% CO\\2\\) to the hematopoietic cells. Two days prior to the completion of cell production, the cell culture effluent will be sampled to allow for bacterial and fungal testing including gram stain, endotoxin testing and mycoplasma. At the completion of the cell expansion process (12 days), the non-adherent fraction will be removed from the cell culture devices by draining the growth medium from the cell culture devices into the harvest bag. The devices will then be rinsed by using a syringe to inject 50 ml of an HBSS solution into an access port. This is followed by agitation of the cell culture device and collection of the rinse into the harvest bag. The adherent layer will be detached from the cell culture device surface by injection of 50 ml of Trypsin-EDTA solution via an access port. This is again followed by agitation of the cell culture device and collection of the rinse into the harvest bag. The chamber will be then given a final rinse with 50 ml of HBSS, again by injection via an access port. This is followed by agitation of the cell culture device and collection of the rinse into the harvest bag. The expanded cells will be washed according to the procedure outlined in the Operator's Manual. All subjects will receive freshly harvested expanded cells. The expanded cells must be greater than 80% viable, as determined by Trypan blue dye, and the minimum total cell number, as determined by an automated cell counter, will be 1.6 x 10/9/ cells. As part of the standard laboratory in this study, the total cell count, CFU-GM and LTC-IC will be determined for the starting and final cell number. The pre and post expansion sample will be sent for cytology and immunocytochemistry for breast cancer cells. Pre-transplant Evaluation of the cultured Cells: 48 hours prior to the collection of the expanded cells, the effluent from the CPS will be tested for bacterial and fungal contamination, as described above. If the bone marrow cultures are either visibly contaminated or are positively cultured for bacterial or fungal contamination, or if the cultures die, the expanded cells will not be returned to the subject, who will then simply receive her cryopreserved bone marrow. Flow Cytometry: Aliquots of the ex vivo produced cells (approximately 10 x 10/6/) will be removed at 12 days, placed in a tube containing sterile buffered medium, and shipped by overnight mail carrier to Aastrom Biosciences, Inc., Domino's Farms, 24 Frank Lloyd Wright Drive, Lobby L, Ann Arbor, MI 48105. These cells will be analyzed for the presence of several cell surface markers (CD34, CD11b, CD15, CD33, CD3, CD4, CD8, CD19, CD71, and glycophorin A and other appropriate markers) in the laboratory at Aastrom as potential correlates for the cell production process. The Aastrom Laboratory operates under GLP guidelines. Release Criteria: Cells produced in the Aastrom CPS will be considered eligible for release and reinfusion if greater than 1.6 x 10/9/ nucleated cells/kg are recovered after the expansion period and cell washing, and if greater than 80% of the nucleated cells are viable as judged by exclusion of Trypan blue dye. Microbial contamination studies collected from the expansion on Day 10 must be negative. If the expansion is not deemed sufficient, a patient will receive her backup marrow instead, without infusion of the expanded cells. 5.4 High Dose CBT and Infusion of Ex Vivo Produced Cells 5.4.1 The CBT Regimen Cyclophosphamide 2.0 gm/m/2/ IV Days -7, -6, -5 (total dose 6 gm/m/2/) with Mesna 500 mg/m/2/ IV 1/2 hour before the first dose of Cyclophosphamide then 2 gm/m/2/ as a continuous infusion over 24 hours for 3 days. Thiotepa 240 mg/m/2/ (total 720 mg/m/2/) will be diluted in normal saline and given over 4 hours daily Days -7, -6, -5. BCNU 150 mg/m/2/ will be dissolved in 100 ml of D5W and given IV piggyback on Days -7, -6, -5 over 40 minutes (total dose 450 mg/m/2/). The ex vivo-produced cells are infused intravenously on Day 0 (the 7th day after the start of chemotherapy). Patients will be premedicated with Tylenol 650 mg PO, Benadryl 50 mg IVPB and Hydrocortisone 50 mg IVPB prior to each infusion. 5.4.2 Post-Transplant Growth Factor Support G-CSF (5 mcg/kg/d) will be administered SQ until granulocytes greater than 2.0 x 10/9//I or greater than 1.0 x 10/9//I for 3 days. If granulocytes fall to less than 1.0 x 10/9//I, hematopoietic growth factor treatment can be resumed as indicated to maintain an absolute granulocyte count greater than 1.0 x 10/9/L. GM-CSF 250 mg/m2/d may be used in patients intolerant to G-CSF. 5.4.3 Neutrophil Engraftment and Stopping Rules Neutrophil engraftment is defined as recovery of granulocytes to 0.5 x 10/9//I. Back-up autologous bone marrow will be infused intravenously per the following stopping rules: 5.4.3.1 Background . back-up cells will always be administered to subjects on Day + 16 if ANC is less than 0.5 x 10/9//I; . if back-up cells are administered to a subject on Day +16, it is reasonable to assume that an ANC level of 0.5 x 10/9//I can only be reached between Day +16 and Day +20 if the cells produced in the CPS alone contribute to a subject's recovery, because the administration of back-up cells would not be expected to impact engraftment so rapidly, between Days +16 and +20; . it is relevant to point out that ANC recovery in the Day +16 to +20 timeframe is often experienced in standard bone marrow transplantation. 5.4.3.2 Stopping Rules With the above as background, stopping rules will be as follows: . the trial will be stopped and reevaluated if two subjects fail to reach ANC 0.5 x 10/9//I by Day +20, even with the administration of back-up cells on Day +16; . the trial will also be stopped and reevaluated if four of the first five subjects, or if any five of the ten total subjects, required the administration of back-up cells because they failed to reach ANC 0.5 x 10/9//I on or before Day +16. 6.0 PRETREATMENT EVALUATION 6.1 Complete history and physical examination, including Zubrod performance status (Appendix C) 6.2 CBC, diff, and platelet count 6.3 SMA 12 and electrolytes 6.4 PT, PTT 6.5 Cardiac ejection fraction 6.6 Pulmonary function - DLCO 6.7 HIV, hepatitis, HTLV-1 (1764 panel) 6.8 Pregnancy test (in fertile women) 6.9 Tumor staging as indicated including bone scan with Xray of hot spots, CXR, CT scan abdomen, tumor markers, such as CEA will be assessed. 6.10 Bilateral bone marrow aspirate and biopsy 7.0 STUDY PROCEDURES AND EVALUATIONS 7.1 Interim history, physical examination and toxicity assessment daily while in hospital and at least weekly until WBC greater than 3000 and platelets greater than 100,000.

The study monitors will promptly review all incoming data to identify inconsistent or missing data and adverse effects. Data problems will be addressed in telephone calls and correspondence to the investigational site and during site visits. Clinical monitoring procedures are described in Section 12 of this protocol. The Medical Monitor will receive immediate notification of adverse reactions Grade greater than or equal to 3. Both the site and Aastrom will maintain secure hard copy Case Record Forms and data files. 9.0 ADVERSE EFFECTS All adverse effects, whether or not considered anticipated, must be recorded in PDMS. Unanticipated effects, as defined below, must be reported promptly to the sponsor for further evaluation and adequate required reporting to IRBs and investigators. 9.1 Anticipated Adverse Effects The preliminary clinical experience has not identified any serious adverse effects on health or safety caused by or associated with the CPS and no adverse effects related to the ex vivo use flt3 ligand are anticipated. Patients undergoing high dose chemotherapy are anticipated to experience anorexia, nausea, vomiting, mucositis, pancytopenia and associated infections while neutropenia. Some patients may develop organ toxicities from high dose therapy. The anticipated events are therefore those associated with bone marrow transplantation and/or chemotherapy. 9.2 Unanticipated Adverse Effects An unanticipated adverse effect is: - Any serious effect on health or safety or any life-threatening problem, or death caused by, or associated with, a device, if that effect, problem, or death was not previously identified in nature, severity, or degree of incidence in the investigational plan, or any other unanticipated serious problem that relates to the rights, safety or welfare of subjects. [21 CFR 812.3(s)] - In particular, any unexpected grade III or IV toxicities or any other serious event that might be attributable to the infusion of the expanded hematopoietic cells. Reporting requirements: - Unanticipated adverse effects should be reported to the Aastrom Study Director, Thomas E. Muller, Ph.D., Vice President Regulatory Affairs, immediately by the Investigator and subsequently to BRI. - Aastrom requires an immediate telephone report followed by a written report within 5 days. - An investigator shall submit to Aastrom and the reviewing IRB a report of any unanticipated adverse device effect occurring as soon as possible, but no later than 10 working days after the investigator learns of the effect [21 CFR 812.150(a)(1)]. Aastrom shall immediately conduct an evaluation and report the results of the evaluation to FDA and to reviewing IRB's and participating investigator(s) within 10 working days after the sponsor first receives the notice of the effect [21 CFR 812.150(b)(1)]. If Aastrom determines that an unanticipated adverse effect presents an unreasonable risk to subjects, all investigations or parts of investigations presenting that risk shall be terminated as soon as possible [21 CFR 812.46(b)]. 9.3 DEPARTURE FROM PROTOCOL When a situation occurs which requires a departure from the protocol, the Principal Investigator or other physician in attendance will contact the Medical Monitor by telephone: Thomas E. Muller, Ph.D. Vice President Regulatory Affairs Aastrom Biosciences, Inc. 24 Frank Lloyd Wright, Lobby L Ann Arbor, MI 48105 Telephone: 313-930-5555 Fax: 313-665-0485 Contact with the Medical Monitor will be made as soon as possible in order to discuss the situation and agree on an appropriate course of action. The patient's medical records and source documents will describe the departure from the protocol and the circumstance requiring it. 10. STATISTICAL CONSIDERATIONS AND DATA ANALYSIS 10.1 Evaluation of the Data All subjects will be evaluated. Descriptive statistics will be presented for demographic variables and baseline characteristics such as age, sex, medical history, physical examination results, cost information (especially as this relates to morbidity). The primary endpoint is the safety of the cells produced in the CPS. To assess the hematopoietic recovery post-infusion with ex vivo-produced cells, the day of engraftment is defined by the first day on which granulocytes are greater than 0.5 times 10/9//I are observed. Other secondary endpoints include nadir WBC and platelet count, febrile days, treatment related complications, antitumor response, and survival. Secondary Endpoints: a. The day of platelet transfusion independence with platelet count greater than 20,000/mm/3/, 50,000/mm/3/ and 100,000/mm/3/ as defined by first of two consecutive time points on which platelet counts meet these endpoints not related to transfusion b. Packed red blood cell transfusion and platelet transfusion requirements. c. Number of documented infections. d. Number of bleeding episodes. e. Number of days of hospitalization. f. Tumor response and response duration g. Patient survival at 90 days post transplant. 10.2 Safety variables Safety variables summarized will include incidence of adverse effects (including duration, severity, and outcome). Other safety variables reported will include the incidence and types of laboratory abnormalities. When the frequencies are sufficiently large, a Fisher's exact test or Chi-square test may be used to compare enrolled subjects and historical controls including approximately 65 patients receiving autologous bone marrow transplants without expansion using the same preparative regimen (DM92-060). 10.3 Biological Effect Variables The following biological effects will be summarized: - Incidence of febrile neutropenia - Time to platelet transfusion independence - Antibiotic usage: Number of days on antibiotics Number of total antibiotic days (Number antibiotics times number days) Number of days on antifungals Number of days on antivirals - Number of documented infections - Time to neutrophil engraftment - Length of initial hospital stay 11.0 CLINICAL SUPPLIES A complete CPS description is provided in the Operator's Manual. 11.1 Materials and Supplies 11.1.1 CPS Aastrom will supply the CPS, which includes the cell culture device.

A final inventory will then be performed. 13.1.9.8 Laboratory Normal Values The investigational site must maintain a current copy of normal values used by that site's clinical laboratory. The Principal Investigator must assess the clinical significance of all abnormal laboratory values. All clinically significant abnormalities must be characterized by the Principal Investigator as treatment- related, not treatment-related, or of uncertain etiology; all abnormalities judged treatment-related or of uncertain etiology must be repeated. Any abnormal values that persist should be followed at the Principal Investigator's discretion. In some cases, significant changes within the normal range will require similar judgment. 13.1.9.9 Disclosure of Data All information concerning this clinical study are considered confidential. The Principal Investigator agrees to use this information only to accomplish this study and will not use it for other purposes without Aastrom's written consent. It is understood by the Principal Investigator that the information developed in the clinical study may be disclosed as required to the United States Food and Drug Administration. In order to allow for the use of the information derived from the clinical studies, it is understood that there is an obligation to provide Aastrom with complete test results and all data developed in the study.

THE UNIVERSITY OF TEXAS M.D. ANDERSON CANCER CENTER INFORMED CONSENT PROTOCOL TITLE: CLINICAL FEASIBILITY STUDY OF EXPANDED PROGENITOR CELLS FOR HEMATOPOIETIC ENGRAFTMENT IN PATIENTS WITH BREAST CANCER 1. ____________________________ ____________________ PARTICIPANT'S NAME I.D. NUMBER You have the right to know about the procedures that are to be used in your participation in clinical research so as to afford you an opportunity to make the decision whether or not to undergo the procedure after knowing the risks and hazards involved. This disclosure is not meant to frighten or alarm you; it is simply an effort to make you better informed so you may give or withhold your consent to participate in clinical research. This informed consent does not supersede other informed consents you may have signed. DESCRIPTION OF RESEARCH - ----------------------- 2. PURPOSE OF STUDY: Chemotherapy at standard or usual doses does not always kill all the cancer cells. In such cases, higher doses of chemotherapy may be helpful. However, these higher doses may destroy normal bone marrow as well as cancer cells, so previously collected blood forming bone marrow cells are given by vein to replace the damaged bone marrow. The goal of this clinical research study is to determine whether we can speed up recovery after high-dose chemotherapy and bone marrow transplant in patients with breast cancer growing the cells in the laboratory before infusion. 3. DESCRIPTION OF RESEARCH: This study will include patients with stage 4 breast cancer. 12 days before treatment begins, about 100 cc of bone marrow will be removed from patient's hip with a syringe and needle while under general anesthesia. A sample of the marrow will be placed in an investigational device that will increase (expand) the number of blood-forming cells (stem cells). Patients will also have a full bone marrow harvest under anesthesia, (approximately 1 quart), collected at the same time or another occasion. This will be saved as a back up to be given back by vein in case of poor recovery of blood counts after infusion of the expanded cells. The patient will stay in the hospital during the high-dose chemotherapy and transplant procedure. The chemotherapy drugs in this treatment plan are cyclophosphamide, carmustine (BCNU), and thiotepa. These drugs in lower doses are FDA-approved and commercially available. These drugs, at the same or higher doses, have been used in other bone marrow transplant studies at M.D. Anderson and are considered active against breast cancer and reasonably safe. Before treatment begins, a catheter (a special tube) will be inserted into a vein in the patient's chest. The chemotherapy drugs, fluids, antibiotics, bone marrow, and other blood products will be given through the catheter. Each drug will be given to the patient for 3 days. One week after the start of chemotherapy, the patient will receive the expanded blood-forming cells. Patients will undergo frequent blood tests over the next several weeks to monitor their recovery and to check for side effects of the treatment. The patient will probably be in the hospital for about 3 weeks. About 10 patients will take part in this study. 4. RISKS, SIDE EFFECTS, AND DISCOMFORTS TO PARTICIPANTS: Risks of Bone Marrow Collection ------------------------------- Bone marrow is collected from several places in the hip with a syringe and needle while the patient is under general anesthesia. The patient may have pain at the sites that the marrow was taken from. Rarely, patients have a reaction to the anestesia (sometimes fatal), bleeding, infection, or injury to the sciatic nerve, which runs along the leg. Risks of High Dose Chemotherapy ------------------------------- Anti-cancer drugs injure normal tissues as well as cancer cells. Side effects of these drugs may include: hair loss, nausea, vomiting, diarrhea, mouth ulcers (sores), skin rashes, bleeding and infection, weakness, slight risk of damage of the heart, lung, liver, kidney, or nervous system. Most of these side effects can occur even at standard doses of these drugs. However, using high doses makes it more likely that patients will have bleeding, infection, and other side effects. Risks of Bone Marrow Transplant ------------------------------- In a preliminary study involving 10 patients none had any side effects from the expanded cell infusion. Potential risks of infusing expanded blood- forming cells include: shortness of breath, strain on the heart, and allergic reaction to the chemicals used while processing or storing the expanded blood-forming cells. After the high-dose chemotherapy, the patient's blood cell counts fall to very low values. When blood cell counts are low, the patient is at high risk for bleeding and infection. At this point, the patient usually requires antibiotics and transfusions of red blood cells and platelets. (Red blood cells carry oxygen through the body, and platelets help control bleeding). Approximately 5% of patients who receive an autologous transplant for breast cancer die of complications from the transplant, usually a side effect of the high dose chemotherapy or an infection that develops while blood counts are low. This clinical research study may involve unforeseeable risks to the participant. 4a. This clinical research may involve unforeseeable risks to unborn children; therefore, the participants should practice adequate methods of birth control throughout the period of their involvement in the clinical research study if they are sexually active. To help prevent injury to children, female participants should refrain from breast feeding during participation in the clinical research study. 5. POTENTIAL BENEFITS: The expanded blood-forming cells to the bone marrow that is transplanted may help the bone marrow recover and start producing new blood cells faster. This would reduce the risk of bleeding and infection. By starting with a smaller amount of bone marrow and the effects of the cell culture, it is expected that the chance of malignant cells being infused is reduced. Using high doses of the drugs may cause the cancer to shrink more than it would if lower doses of the same drugs were used. 6. ALTERNATE PROCEDURES OR TREATMENTS: Common drugs used to treat breast cancer include mitomycin, methotrexate, doxorubicin, 5-fluorouracil, vinblastine, cyclophosphamide, taxol. Instead of taking part in the clinical research study described above, patients could receive one or a combination of these drugs at standard doses. Also, patients might be able to take part in clinical research studies of other drugs. Patients could also have a blood stem cell or bone marrow transplant without receiving the expanded blood-forming cells. UNDERSTANDING OF PARTICIPANTS - ----------------------------- 7. I have been given an opportunity to ask any questions concerning the treatment involved and the investigator has been willing to reply to my inquiries. This treatment will be administered under the above numbered and described clinical research protocol at this institution. I hereby authorize Dr. ______________, the attending physician/investigator, and designated associates to administer the treatment. 8.

PURPOSE OF STUDY: Chemotherapy at standard or usual doses does not always kill all the cancer cells. In such cases, higher doses of chemotherapy may be helpful. However, these higher doses may destroy normal bone marrow as well as cancer cells, so a bone marrow transplant is done to replace the damaged bone marrow. The goal of this clinical research study is to determine whether we can speed up recovery after high-dose chemotherapy and bone marrow transplant in patients with breast cancer growing the cells in the laboratory before infusion. (See Section 4.1, Risks of Experimental Protocol.) 3. DESCRIPTION OF RESEARCH: This study will include patients with breast cancer that has spread to the lymph nodes or to other organs. Twelve days before treatment begins, a full bone marrow harvest, approximately one quart, will be obtained from the patients under general anesthesia. An aliquot of the marrow, less than 10%, will be used to innoculate the investigational device, the Cell Production System (CPS), and the bulk of the harvest, other 90%, will be cryopreserved and saved as back-up in case of poor recovery of blood counts after the infusion of the cells produced in the CPS, or for later therapeutic use, if necessary. The patients will stay in the hospital during the high-dose chemotherapy and transplant procedure. The chemotherapy drugs in this treatment plan are cyclophosphamide, carmustine (BCNU), and Thiotepa. These drugs in lower doses are FDA-approved and commercially available. These drugs, at the same or higher doses, have been used in other bone marrow transplant studies at M.D. Anderson and are considered active against breast cancer and reasonably safe. Before treatment begins, a catheter (a special tube) will be inserted into a vein the patient's chest. The chemotherapy drugs, fluids, antibiotics, bone marrow, and other blood products will be given through the catheter. Each drug will be given to the patient for 3 days. One week after the start of chemotherapy, the patient will receive the expanded blood-forming cells. Patients will undergo frequent blood tests over the next several weeks to monitor their recovery and to check for side effects of the treatment. The patient will probably be in the hospital for about 3 weeks. About 14 patients will take part in this study. 4. RISKS, SIDE EFFECTS, AND DISCOMFORTS TO PARTICIPANTS: 4.1 Risks of Experimental Protocol ------------------------------ I have been advised that the Cell Production System, used in this experimental protocol, has been evaluated previously in a clinical feasibility (safety) study without any adverse events (see Section 4.4). Nevertheless, I understand that this experimental protocol may represent a relatively high risk clinical procedure that may cause delayed neutropenia (low white cell counts) and thrombocytopenia (low platelet counts), and delayed engraftment of my transplant. Prolongation of low white counts or platelet counts may increase the risk of infection and bleeding, may prolong hospitalization and can potentially increase the risk of death. However, the risk of these complications is unknown, and experience with transplants that have prolonged low white counts and platelet counts do not appear to have an increased risk of fatal complications. Prolonged time to engraftment and loss of engraftment can be occasionally seen even when standard sources of stem cells are used, such as unexpanded bone marrow or peripheral blood stem cells. I also understand that every effort will be used to ensure my safety and recovery, including the availability and potential administration of back- up bone marrow obtained as part of my bone marrow harvest. The additional back-up marrow will be given if there is a delay in blood count recovery, or if blood counts decrease after initial engraftment. I understand that I have an option to select to have my physician employ alternate procedures of treatment for my disease, as outlined in Section 6 of this document. 4.2 Risks of Bone Marrow Collection ------------------------------- Bone marrow is collected (harvested) from several places in the hip with a syringe and needle while the patient is under general anesthesia. The patient may have pain at the sites that the marrow was taken from. Rarely, patients have a reaction to the anesthesia (sometimes fatal), bleeding, infection, or injury to the sciatic nerve, which runs along the leg. 4.3 Risks of High Dose Chemotherapy -------------------------------- Anti-cancer drugs injure normal tissues as well as cancer cells. Side effects of these drugs may include: hair loss, nausea, vomiting, diarrhea, mount ulcers (sores), skin rashes, bleeding and infection, weakness, slight risk of damage of the heart, lung, liver, kidney, or nervous system. Most of these side effects can occur even at standard doses of these drugs. However, using high doses makes it more likely that patients will have bleeding, infection, and other side effects. 4.4 Risks of Bone Marrow Transplant ------------------------------- In a preliminary study involving 10 patients none had any side effects from the expanded cell infusion. Potential risks of infusing expanded blood- forming cells include: shortness of breath, strain on the heart, and allergic reaction to the chemicals used while processing or storing the expanded blood-forming cells. After the high-dose chemotherapy, the patient's blood cell counts fall to very low values. When blood cell counts are low, the patient is at high risk for bleeding and infection. At this point, the patient usually requires antibiotics and transfusions of red blood cells and platelets. (Red blood cells carry oxygen through the body, and platelets help control bleeding.) Approximately 5% of patients who receive an autologous transplant for breast cancer die of complications from the transplant, usually a side effect of the high dose chemotherapy or an infection that develops while blood counts are low. This clinical research study may involve unforeseeable risks to the participant. This clinical research may involve unforeseeable risks to unborn children; therefore, the participants should practice adequate methods of birth control throughout the period of their involvement in the clinical research study if they are sexually active. To help prevent injury to children, female participants should refrain from breast feeding during participation in the clinical research study. 5. POTENTIAL BENEFITS: The expanded blood-forming cells from the bone marrow that is transplanted may help the bone marrow recover and start producing new blood cells faster. This would reduce the risk of bleeding and infection. By starting with a smaller amount of bone marrow it is expected that the chances of malignant cells being in the marrow collection is less. Using higher doses of the drugs may cause the cancer to shrink more than it would if lower doses of the same drugs were used. The back-up bone marrow, obtained as part of my bone marrow harvest, may be available for my further treatment later, should this become necessary. 6. ALTERNATE PROCEDURES OR TREATMENTS: Common drugs used to treat breast cancer include mitomycin, methotrexate, doxorubicin, 5-fluorouracil, vinblastine, cyclophosphamide, taxol. Instead of taking part in the clinical research study described above, patients could receive one or several of these drugs at standard doses. Also, patients might be able to take part in clinical research studies of other drugs. Patients could also have a blood stem cell or bone marrow transplant without receiving the expanded blood-forming cells. UNDERSTANDING OF PARTICIPANTS - ----------------------------- 7.

Should the investigational agent become commercially available during the course of the study, I understand that I may be required to cover the cost of subsequent doses. Costs related to my medical care including expensive drugs, tests or procedures that may be specifically required by this clinical research study shall be my responsibility unless the sponsor or other agencies contribute toward said costs. I have been given the opportunity to discuss the expenses or costs associated with my participation in this research activity. 12. It is possible that this research project will result in the development of beneficial treatments, new drugs, or possible patentable procedures, in which event I cannot expect to receive any compensation or benefits from the subsequent use of information acquired and developed through participation in this research project. 13. I understand that refraining from breast feeding and practicing effective contraception are medically necessary and a prerequisite for my participation in this clinical research study. Should contraception be interrupted or if there is any suspicion of pregnancy, my participation in this clinical research study will be terminated at the sole discretion of the investigator. 14. I may discuss any questions or problems during or after this study with Dr. Richard Champlin at 713/792-3611. In addition, I may discuss any problems I may have or any questions regarding my rights during or after this study with the Chairman of the Surveillance Committee at 713/792-3220 and may in the event of any problem arises during this clinical research contact the parties named above.

                               LICENSE AGREEMENT

By this Agreement, Ann Arbor Stromal, Inc. (hereinafter "Ann Arbor Stromal") and
the Regents of The University of Michigan, a constitutional corporation of the 
State of Michigan (hereinafter "University") agree as follows:

1.  INCORPORATION BY REFERENCE
    --------------------------

    Incorporated by reference with full force and effect to the provisions,
    definitions, terms and conditions of this License Agreement (hereinafter
    "License") are the provisions, definitions, terms and conditions of the
    Research Agreement to which this License is attached, including the Option
    Agreement and its Appendices.

2.  DEFINITIONS
    -----------

    2.1  "Effective Date" of this License shall be the date of completed
         execution by both Parties in accordance with the provisions of Article
         9 entitled "License", in the abovementioned Research Agreement to which
         this License is attached.

    2.2  "Parties", in singular or plural usage as required by the context,
         means Ann Arbor Stromal and/or University.


                                       1

 
     2.3  "Territory" means all countries of the world.

     2.4  "Licensed Technology" means all patentable inventions and Know-how for
          the production of red blood cells, white blood cells, platelets and
          bone marrow cells, which are either described in University Project
          proposal, or conceived or reduced to practice as part of Project, or
          conceived or reduced to practice, whether or not pursuant to or as
          part of the Project, by Drs. Stephen G. Emerson, Michael F. Clarke or
          Bernhard O. Palsson, or those working under their direction, during
          the term of their participation in the Project and Ann Arbor Stromal's
          funding of the Project.

     2.5  "Licensed Patent(s)" means any and all pending patent applications(s)
          included within Licensed Technology, whether now existing or hereafter
          filed, both domestic and foreign, and any patents issuing therefrom.

     2.6  "Valid Claim(s)" means any claim(s) pending in a patent application or
          in an unexpired patent included within the Licensed Patents which has
          not been held unenforceable, unpatentable, or invalid by a decision of
          a court or other governmental agency of competent jurisdiction,
          unappealable or unappealed within the time allowed for appeal, and
          which has not been admitted to be invalid or unenforceable through
          reissue or disclaimer. If in any country there should be two or more
          such decisions conflicting with respect to the validity of the same
          claim, the decision of the higher or highest tribunal shall thereafter
          control;

                                       2


 
          however, should the tribunals be of equal rank, then the decision or
          decisions upholding the claim shall prevail when the conflicting
          decisions are equal in number, and the majority of decisions shall
          prevail when the conflicting decisions are unequal in number.

     2.7  "Know-How" means (a) all information, data and knowledge contained in
          patent applications or patents which are at anytime included in the
          definition of Licensed Patents, and (b) any other methods, procedures,
          processes, compositions of matter, biological materials, trade
          secrets, experience, work products technical information, inventions,
          discoveries, improvements, reports, data, results from experiments,
          developmental efforts and demonstrations and subject matter related to
          the Project, whether or not contained in Licensed Patents.

     2.8  "Product(s)" means any red blood cells, white blood cells, platelets
          and bone marrow cells as well as any components, by-products, progeny
          or derivatives thereof and any factor, composition, substance,
          equipment, mechanism, device or other property and combinations
          thereof, the manufacture, use or sale of which would, but for this
          License, comprise an infringement of one or more Valid Claims.

     2.9  "Combination Sales" shall mean sales of Product by Ann Arbor Stromal,
          its Affiliates or subsidiaries as a combined package comprised in part
          of Product and in part of one or more other products or parts which
          constitute either an

                                       3


 
         active ingredient or a significant delivery system or mechanism and
         which could readily be sold by Ann Arbor Stromal, its Affiliates or
         subsidiaries and used for their intended purpose by their purchasers
         without the incorporation or use of Product.

    2.10 "Net Sales" means the sum, over the term of this License, of all
         amounts of monies received and all other consideration received (when
         in a form other than cash or its equivalent, the fair market value
         thereof when received) by Ann Arbor Stromal, its Affiliates or
         subsidiaries from purchasers or users from or by reason of the sale,
         distribution or use of Product, less any amounts collected for taxes,
         including sales and use taxes, customer charges, allowances (including
         any allowance for bad debts), import and export duties and other
         governmental charges, prompt payment or other customary trade
         discounts allowed or taken, credits or refunds for goods returned and
         transportation and delivery charges (including insurance premiums).

         If Product is sold in Combination Sales, then Net Sales shall be
         computed in the following manner: First, gross revenues from the
         Combination Sales shall be reduced by any applicable deductions
         itemized in the first paragraph of this definition in order to arrive
         at "Combination Net Sales"; second, Net Sales shall be calculated by
         employing the following formulas:

                                       4

 
                 C - p = Net Sales.

         In the above formula, "p" is the fair market value of all other
         products or parts which constitute an active ingredient or significant
         delivery system or mechanism within the Combination Sale and C is
         equal to Combination Net Sales.

         All fair market value calculations made by Ann Arbor Stromal hereunder
         shall be in good faith determined by Ann Arbor Stromal in the event no
         market price is available. In the event the University disagrees with
         any aspect of Ann Arbor Stromal's implementation of this definition,
         University may request that such dispute be submitted to arbitration
         as described in Article 17 and Ann Arbor Stromal hereby agrees to
         promptly grant and fully cooperate with such request.

    2.11 "Affiliate" shall mean any corporation, partnership, proprietorship or
         other entity controlled by, controlling, or under common control with
         Ann Arbor Stromal, and shall include any corporation, partnership,
         proprietorship or other entity directly or indirectly owning, owned by
         or under common ownership with the party in question to the

                                       5

 
         extent of twenty-five percent (25%) or more of the equity or voting
         shares, including shares owned beneficially by such party.

    2.12 "Calendar Quarters" means the three (3) months ending on the last day
         of March, June, September and December of each year.

3.  GRANTS
    ------

    3.1  Subject to the conditions and provisions of this License, University
         hereby grants to Ann Arbor Stromal an exclusive world-wide license,
         without the right to grant sublicenses, except as described in
         paragraph 3.2 below, under Licensed Patents and to use Know-How to
         make, use, and sell Product(s), except that University hereby retains
         the right to use Licensed Patents and Know-How solely for research
         purposes, and except that to the extent funding from federal agencies
         results in Licensed Technology or Licensed Patents in addition to
         Project funding, the federal government may have its standard license
         rights with respect to such Licensed Technology or Licensed Patents.

    3.2  If at any time Ann Arbor Stromal wishes to grant sublicense rights
         under its exclusive license rights granted herein, University and Ann
         Arbor Stromal shall negotiate in good faith in order to allow Ann
         Arbor Stromal to enter into such sublicensing arrangements with a
         royalty return on Product(s) to University comparable to royalties
         earned by

                                       6

 
         University under this License. Subject only to this understanding and
         the need to have any sublicensing arrangements reflect a fair market
         value return to Ann Arbor Stromal as in an arms length transaction, it
         is the understanding of the parties that Ann Arbor Stromal should be
         able to make its own decisions as to the appropriate mechanisms,
         including sublicensing, for exploiting the Licensed Technology.

    3.3  The University and Ann Arbor Stromal hereby assert that, to the best of
         their knowledge as of the date of execution of the Option Agreement,
         there do not exist any University patents or pending patents, other
         than the Licensed Patents of this License Agreement, which would be
         infringed by the practice of the Licensed Patents of this License or
         which would otherwise prevent the practice of any of the Valid Claims.
         If, however, such University patents or patent applications are
         subsequently found to have existed prior to the date of the Option
         Agreement, University shall use reasonable efforts to grant to Ann
         Arbor Stromal a nonexclusive license to such patents and/or patent
         applications, to the extent necessary for the practice of the Licensed
         Technology of this License.

4.  ROYALTIES
    ---------

    4.1  The license rights granted to Ann Arbor Stromal herein are subject to
         Ann Arbor Stromal's payment of royalties to University according to the
         provisions of this Section 4.

                                       7

 
    4.2  For Product(s) defined in 2.8 herein, Ann Arbor Stromal will pay
         University a royalty equal to two percent (2%) of Net Sales of such
         Product(s) by Ann Arbor Stromal and Affiliates for the life of the last
         to expire of Licensed Patents.

    4.3  Where Net Sales form the basis upon which payment to University is
         derived, the obligation to pay University under this Section 4 is
         imposed only once with respect to the same unit of Product regardless
         of the number of Valid Claims, Licensed Patents or items of Know-How
         covering the same; however, for purposes of determination of payments
         due hereunder, whenever the term Product may apply to a property during
         various stages of manufacture, use or sale, Net Sales, as otherwise
         defined shall be derived from the sale, distribution or use of such
         Product by Ann Arbor Stromal and Affiliates at the stage of its highest
         invoiced value to unrelated third parties.

    4.4  If at any time or from time to time an unrelated third party in any
         country shall, under right of a compulsory license granted or ordered
         to be granted by a competent governmental authority, manufacture, use
         or sell any Product with respect to which royalties shall be payable
         pursuant to Paragraph 4.2 of this Section, then Ann Arbor Stromal, upon
         notice to University and during the period such compulsory license
         shall be effective, shall have the right to reduce such royalty on each
         unit of Product sold

                                       8


 
         in such country to an amount no greater than the amount payable by said
         third party in consideration of its compulsory license.

5.  REPORTS
    -------


    5.1  Within sixty (60) days after the close of each Calendar Quarter during
         the term of this License (including the last day of any such Calendar
         Quarter following any termination of this License), Ann Arbor Stromal
         shall report to University all royalties accruing to University under
         Section 4 during such Calendar Quarter. Such quarterly reports shall
         indicate for each Calendar Quarter the gross sales and Net Sales of
         Product; such reports shall also indicate Net Sales with respect to
         which payments are due and the amount of such payments, as well as the
         various calculations used to arrive at said amounts, including the
         quantity, description (nomenclature and type designation), country of
         sale and country of manufacture of Product(s). In case no payment is
         due for any such period, Ann Arbor Stromal shall so report.

    5.2  Ann Arbor Stromal covenants that it will promptly establish and
         consistently employ a system of specific nomenclatures and type
         designations for Product(s) so that the various types can be identified
         and segregated, and Ann Arbor Stromal and Affiliates will consistently
         employ such system when rendering invoices thereon and henceforth
         agrees to inform University, or its auditors, when requested as to

                                       9


 
         the details concerning such nomenclature system as well as to all
         additions thereto and changes therein.

    5.3  Ann Arbor Stromal shall keep and it shall cause its Affiliates to keep,
         true and accurate records and books of account containing data
         reasonably required for the computation and verification of payments to
         be made as provided by this License, which records and books shall be
         open for inspection upon reasonable notice during business hours by
         inspectors selected by and at the expense of University for the purpose
         of verifying the amount of payments due and payable. Said right of
         inspection will exist for six (6) years from the date of origination of
         any such record and this requirement and right of inspection shall
         survive any termination of this License for a period of three (3) years
         after such termination. However, in the event that such inspection
         reveals an underpayment of royalties to University in excess of five
         percent (5%), then said inspection shall be at Ann Arbor Stromal's
         expense and such underpayment shall become immediately due and payable
         to University.

    5.4  The reports provided hereunder shall be certified by an authorized
         representative of Ann Arbor Stromal to be correct to the best of Ann
         Arbor Stromal's knowledge and information.

                                      10


 
6.  TIMES AND CURRENCIES OF PAYMENTS
    --------------------------------

    6.1  Payments accrued at the close of each Calendar Quarter shall be due and
         payable in Ann Arbor, Michigan on the date each quarterly report,
         provided for under Section 5 above, is due and shall be paid in United
         States dollars.  Ann Arbor Stromal agrees to make all payments due
         hereunder to University by check addressed to the University's
         Intellectual Properties Office or by wire transfer to the bank account
         designated by University with telephonic confirmation of receipt
         thereof.

    6.2  On all amounts outstanding and payable to University, interest shall
         accrue from the date such amounts are due and payable at a rate of two
         (2) points above the prime lending rate as established by the Chase
         Manhattan Bank, N.A. in New York City, New York, or at such lower rate
         as may be required by law.

    6.3  Any United States currency payments hereunder shall be determined by
         converting foreign currencies into their equivalent in United States
         dollars at the exchange rate of such currency as reported (or if
         erroneously reported, as subsequently corrected) in the Wall Street
         Journal on the last business day of the Calendar Quarter during which
         such payments accrue (or if not reported on that date, as quoted by the
         Chase Manhattan Bank, N.A. in New York City, New York).

                                      11

 
7.  COMMERCIALIZATION
    -----------------

    7.1  Ann Arbor Stromal agrees to use commercially reasonable efforts in
         proceeding with the development, manufacture, marketing and sale of
         Products to commercially exploit the Licensed Technology and in
         creating a supply and demand for same; provided, however, Ann Arbor
         Stromal shall be entitled to exercise prudent business judgment in
         meeting its obligations hereunder.

    7.2  Where Ann Arbor Stromal engages in continuing development with respect
         to Product(s), Ann Arbor Stromal shall keep University informed of such
         developments in writing. Ann Arbor Stromal shall promptly inform
         University of any patent applications, or similar applications,
         relating to Product(s) or improvements thereon, filed by or on behalf
         of Ann Arbor Stromal or Affiliates anywhere in the world.

8.  INFRINGEMENT
    ------------

    8.1  In the event a third party is infringing a Valid Claim by making, using
         or selling Product(s) as defined herein, Ann Arbor Stromal shall have
         the right to bring suit in its own name. University agrees to use
         reasonable efforts to cooperate in the prosecution of such suit. Ann
         Arbor Stromal shall bear the expense of any such litigation and, except
         as described in Paragraph 8.5 below, shall have full authority to
         negotiate a settlement on such terms as Ann Arbor Stromal shall
         determine. Ann Arbor Stromal shall

                                      12

 
                                [COPY TO COME]

                                      13

 
    8.3  In the event that during the term hereof there be made against Ann
         Arbor Stromal, any charge for infringement of any third-party patent by
         reason of Ann Arbor Stromal's or Affiliate's manufacture or sale of a
         Product or any customer's use of the Product which charge is grounded
         essentially on an asserted domination by that third-party patent of the
         manufacture, sale or use of such Product, Ann Arbor Stromal shall give
         written notice thereof to University. Ann Arbor Stromal agrees to
         effectuate, if possible, an acceptable change in the Product to avoid
         such alleged infringement. If no such satisfactory change can be
         effectuated, University and Ann Arbor Stromal agree to collaborate and
         enter into discussions with said third party for the purposes of
         negotiating a settlement. If no settlement can be agreed upon by Ann
         Arbor Stromal, University and the third party, Ann Arbor Stromal shall
         have the right, but not the obligation, to defend any suit for
         infringement brought against it by the third party, and if required by
         law or if requested by University, to join University as a party
         defendant. If Ann Arbor Stromal shall elect not to defend such
         infringement suit, Ann Arbor Stromal shall promptly notify University
         to that effect and University shall thereafter have the obligation to
         defend the suit provided Ann Arbor Stromal reimburses the University
         within thirty (30) days of invoicing for all cost and expenses
         (including reasonable attorney fees), and if required by law or if
         requested by Ann Arbor Stromal, to join Ann Arbor Stromal as a party
         defendant.

                                      14

 
    8.4  Ann Arbor Stromal will bear the cost of defending claims of
         infringement or pursuing infringers, except as allowed in Paragraph 8.2
         above. However, Ann Arbor Stromal can be reimbursed for up to one-half
         of the unrecovered amount of such actual and reasonable expenses in the
         following manner: Ann Arbor Stromal can deduct from royalties otherwise
         due and payable to University under the License, up to fifty percent
         (50%) until such time as Ann Arbor Stromal has recovered one-half of
         its actual, reasonable, and otherwise unrecovered expenses.
         University's "obligation" of bearing one-half of Ann Arbor Stromal's
         expenses shall not exceed the ability of the above-described mechanism
         (i.e., a 50% reduction in royalty payments due and payable) to
         reimburse such expenses and University royalty payments otherwise due
         shall never be reduced by more than 50%. Ann Arbor Stromal will make an
         accounting to University of all such expenses as part of its reporting
         obligations under Section 5.

    8.5  Neither University nor Ann Arbor Stromal shall compromise or settle any
         claim or action in any manner that would affect the rights of the other
         Party without the consent of said other Party.

9.  TERMINATION
    -----------

    9.1  With respect to any termination of this License, and except as provided
         herein to the contrary, all rights and

                                      15

 
    obligations of the Parties hereunder shall cease with respect thereto,
    except as follows:

    9.1.1  Obligations to pay royalties and other sums accruing hereunder up to 
           the day of such termination;

    9.1.2  Obligations to pay royalties on Net Sales, subsequent to said date of
           termination of Product(s) in Stock at the date of termination with
           respect to which stock Ann Arbor Stromal shall have a reasonable time
           to sell or liquidate in a reasonable manner as deemed necessary by
           Ann Arbor Stromal under the circumstances;

    9.1.3  Obligations for record keeping and accounting reports for so long as
           Product(s) are sold pursuant to Paragraph 9.1.2 above. At such time
           as there are no sales or other dispositions of Product(s) upon
           termination of this License, Ann Arbor Stromal shall render a final
           report and royalty payment;

    9.1.4  University's rights to audit books and records as described in 
           Section 5 herein;

    9.1.5  Obligations of indemnity under Section 18;

    9.1.6  Any cause of action or claim of Ann Arbor Stromal or University
           accrued or to accrue because of any breach or default by the other
           Party hereunder;

9.2 This License will become effective on its Effective Date and, unless 
    terminated under another, specific provision of

                                      16

 
         this License, will remain in effect until and terminate upon the
         expiration of the later of Ann Arbor Stromal's obligation to pay
         royalties under Paragraph 4.3 herein or the last to expire of Licensed
         Patents. After such full-term termination of this License, Ann Arbor
         Stromal shall have the right to make, use and sell Product(s) without
         further payment to University hereunder.

    9.3  If Ann Arbor Stromal shall at any time default in the payment of any
         royalty or the making of any report hereunder, or shall commit any
         material breach of any material covenant or promise herein contained,
         --------
         or shall make any false report and shall fail to remedy any such
         default, material breach or report within sixty (60) days after written
         notice thereof by University, University may, at its option, terminate
         this License by notice in writing to such effect. In the event of such
         termination, interest shall continue to accrue as described in
         Paragraph 6.2 on any amounts outstanding and payable to University and
         any such termination shall be without prejudice to University's other
         legal rights for breach of this License.

    9.4  In the event that Ann Arbor Stromal desires to terminate this License,
         Ann Arbor Stromal shall serve upon University a notice of termination,
         including a statement of reasons for such termination, at least six (6)
         months before a termination date established by Ann Arbor Stromal. Such
         notice shall be deemed by the parties to be final, and immediately upon
         service of such notice of termination,

                                      17

 
         University shall have the right to begin negotiations and enter into
         agreements with others for the manufacture, sale and use of the
         Product(s), and may, at its option, disclose to said others any and all
         information related to Product(s) other than Confidential Information
         generated or developed solely by Ann Arbor Stromal. During the period
         of time from the notice of termination until termination pursuant to
         this provision, Ann Arbor Stromal shall continue to commercialize
         Product(s) and to make them reasonably available to the public at fair
         market value.

10. ASSIGNMENT
    ----------

    This License shall not be transferable or assignable by either Party without
    the prior written consent of the other Party, which consent shall not be
    unreasonably withheld; and any attempt to transfer or assign this License
    without such consent shall be void from the beginning. No transfer or
    assignment may be made by Ann Arbor Stromal unless and until the intended
    transferee or assignee agrees in writing to accept all of the terms and
    conditions of this License. For purposes of implementing this clause the
    University's consent may only be withheld:

         i) if the University reasonably believes that implementing the terms of
            the proposed transfer or assignment could economically discriminate
            against the University or its employees holding equity in Ann Arbor
            Stromal as compared to any of the other shareholders or investors in
            Ann Arbor Stromal or their principals; or

                                      18

 
         ii)  if the University reasonably believes that the proposed transfer
              or assignment is to a third party which is not in a financial and
              technical position at least equivalent to that of Ann Arbor
              Stromal for purposes of exploiting and commercializing the
              Licensed Technology.


11. REGISTRATION OR RECORDATION
    ---------------------------


    11.1 If the terms of this License, or any assignment or license under this
         License are or become such as to require or make it appropriate that
         the Agreement or license or any part thereof be registered with or
         reported to a national or supranational agency of any area in which Ann
         Arbor Stromal, or Affiliates would do business, Ann Arbor Stromal will,
         at its expense, undertake such registration or report. Prompt notice
         and appropriate verification of the act of registration or report of
         any agency ruling resulting from it will be supplied by Ann Arbor
         Stromal to University.

    11.2 Any formal recordation of this Agreement or any license herein granted
         which is required by the law of any country of the Territory as a
         prerequisite to enforceability of the Agreement or license in the
         courts of any such country or for other reasons shall also be carried
         out by Ann Arbor Stromal at its expense, and appropriately verified
         proof of recordation shall be promptly furnished to University.

                                      19


 
12. EXPORT LAWS AND REGULATIONS OF THE UNITED STATES
    ------------------------------------------------


    12.1 The Export Regulations of the United States Department of Commerce
         prohibit the exportation from the United States of certain types of
         technical data and commodities (listed in the Export Administration
         Regulations), unless the exporter (e.g., Ann Arbor Stromal or
         Affiliates) has received the required General License or Validated
         License, whichever is applicable. In addition, the exporter may be
         required to obtain certain written assurances regarding re-export from
         the foreign importer for certain types of technical data and
         commodities. Prior to its engaging in any export activity, Ann Arbor
         Stromal has advised University that it will receive a copy of the then
         current Export Administration Regulations of the United States
         Department of Commerce and will arrange for a subscription under which
         it will receive Supplementary Bulletins from the United States
         Department of Commerce upon their issuance. Ann Arbor Stromal hereby
         agrees to comply with, and to require Affiliates to comply with, the
         Export Administration Regulations of the United States Department of
         Commerce; and Ann Arbor Stromal hereby gives University the assurances
         called for in the Export Administration Regulations, including the
         assurances called for in Part 379.4 and any successor provisions of
         such regulations.

    12.2 This License shall be subject to all United States Government laws and
         regulations now or hereafter applicable to the subject matter of this
         License.

                                      20

14.  INVALIDITY
     ----------

     In the event that any term, provision, or covenant of this License shall
     be determined by a court of competent jurisdiction to be invalid, illegal,
     or unenforceable, that term will be curtailed, limited, or deleted, but
     only to the extent necessary

                                      21


 
     to remove such invalidity, illegality, or unenforceability, and the
     remaining terms, provisions, and covenants shall not in any way be affected
     or impaired thereby. In the event that the time period of any covenant
     shall be held unenforceable as a matter of law, said covenant will be
     interpreted to be effective for an enforceable time period.

15.  ENTIRE AGREEMENT AND AMENDMENT
     ------------------------------

     This License contains the entire understanding of the Parties with respect
     to the matter contained herein, and supersedes all prior agreements, oral
     or written, and all other communication between them relating to the
     subject matter hereof. The Parties hereto may, from time to time during the
     continuance of this License, modify, vary or alter any of the provisions of
     this License, but only by an instrument duly executed by authorized
     officials of both Parties hereto.

16.  GOVERNING LAW
     -------------

     This License and the relationships between the Parties shall be governed in
     all respects by the law of the State of Michigan, the United States of
     America, except that questions affecting the construction and effect of any
     patent shall be determined by the law of the country in which the patent
     has been granted.

                                      22


 
17.  ARBITRATION AND DISPUTE RESOLUTION
     ----------------------------------

     Any dispute relating to the interpretation or performance of this Agreement
     or the grounds for the termination hereof shall be resolved at the request
     of either party through final and binding arbitration by a single
     arbitrator in accordance with the Commercial Arbitration rules of the
     American Arbitration Association ("AAA"). Such arbitrator shall be selected
     by the mutual agreement of the parties or, failing such agreement, shall be
     selected according to the relevant AAA rules. The parties shall bear the
     costs of such arbitrator and arbitration equally. The prevailing party in
     any such arbitration shall be entitled to its reasonable attorney's fees
     and costs solely at the discretion of the arbitrator in addition to any
     other amount of recovery ordered by such arbitrator. The arbitrator or
     court, as the case may be, shall determine which party is the "prevailing
     party" for purposes of this section. If judicial enforcement or review of
     such arbitrator's award is sought by either party, judgment may be entered
     upon such award in any court of competent jurisdiction. Ann Arbor Stromal
     hereby consents to venue and personal jurisdiction in Ann Arbor, Michigan
     for any such arbitration proceeding and for any court proceeding. The duty
     of the parties to arbitrate any dispute relating to the interpretation or
     performance of this Agreement or the grounds for the termination thereof
     shall survive any termination of this Agreement.

                                      23

 
18.  INDEMNITY:  INSURANCE
     ---------------------

     18.1  Ann Arbor Stromal shall defend, indemnify and hold harmless and
           shall require Affiliates to defend, indemnify and hold harmless
           University, its fellows, officers, employees and agents, for and
           against any and all claims, demands, damages, losses, and expenses
           of any nature (including attorneys' fees and other litigation

                     FIRST AMENDMENT TO LICENSE AGREEMENT

This First Amendment to License Agreement is made as of March 13, 1992,
                                                        ---------------
by and between Aastrom Biosciences, Inc. (formerly Ann Arbor Stromal, Inc.),
a Michigan corporation, (hereinafter "Aastrom") and the Regents of the 
University of Michigan, a constitutional corporation of the State of Michigan 
(hereinafter "University").

                                  RECITATIONS

The following is a recital of facts underlying this Agreement:

A.  On March 13, 1992 the parties hereto have executed a certain License
       --------------
    Agreement ("License Agreement") as contemplated by a certain Research
    Agreement between the parties hereto which was executed by them during
    August of 1989 (the "Research Agreement").  Defined terms not otherwise 
    defined in this First Amendment shall have the meanings set forth in the
    License Agreement.

B.  The parties now wish to amend the License Agreement in certain respects.

NOW, THEREFORE, in consideration of their mutual promises, the parties hereto
agree as follows:

1.  The License Agreement is hereby amended as follows.

    (a) Licensed Technology includes:





 
i)   all patent applications, including related foreign patent applications,
     and patents issuing therefrom identified in Exhibit A attached hereto;

ii)  all Know-How included in patents and patent applications of Exhibit A
     and grant proposals, papers, abstracts and other documents described in
     Exhibit B attached hereto; and

iii) all additional patentable inventions and Know-How for the production of
     red blood cells, white blood cells, platelets and bone marrow cells, which
     is either described in University Project proposal, or conceived or reduced
     to practice as part of Project, or conceived or reduced to pratice, whether
     or not pursuant to or as part of the Project, by Drs. Stephen G. Emerson,
     Michael F. Clarke or Bernhard O. Palsson, or those working under their
     direction, during the term of their participation in the Project and
     Aastrom's funding of the Project.

(b)  Section 3.2 of the License Agreement hereby is amended to read in its
     entirety as follows:

     3.2  Aastrom shall have the right to grant one or more sublicenses for
          third parties to use the rights granted to Aastrom under its exclusive

                                       2


 
license rights granted in this License Agreement; and, subject to approval by
Aastrom, sub-sublicense agreements may also be granted by a third party
sublicensee. All sublicenses and sub-sublicenses, if any, shall provide that the
sublicensee and sub-sublicensee shall comply fully with all provisions of this
License Agreement, including without limitation, paying the same royalty to the
University as is specified in this License Agreement. Notwithstanding any such
sublicensing, Aastrom shall still remain fully responsible and liable for
compliance with all terms of this License Agreement, including compliance by any
and all sublicensees and sub-sublicensees. No consent from University is
required for any sublicense or sub-sublicense, as described above; however,
Aastrom shall provide timely notice of each sublicense hereunder along with
copies of all sublicense agreements. Should Aastrom propose to enter into a
sublicense which reduces any royalties payable to University, or which otherwise
modifies any of the rights of University under this License Agreement, then no
such sublicense can be entered into without the prior written consent of
University and any

                                       3

 
          such sublicense entered into without prior written consent of
          University shall be void from the beginning. For example, if the
          proposed sublicensee is to issue stock to Aastrom in lieu of
          royalties, or if a proposed sublicensee is to make a lump sum front-
          end payment as a set-off against or in lieu of future royalties, then
          there shall be negotiations between Aastrom and University for an
          equitable allocation of said consideration in lieu of royalties, with
          the mutual consent of Aastrom and University required for any such
          non-conforming sublicense agreement.

2.  Article 13 of the License Agreement, entitled "Notices", is amended as
    follows:

    i)    Provision for notice to Robert Kunze and Kenneth Guernsey is hereby
          deleted; and

    ii)   Notice to Aastrom shall be provided to:

          Aastrom Biosciences, Inc.
          President/CEO
          P.O. Box 130469
          Ann Arbor, Michigan 48113-0469

                                       4

 
3.  As amended hereby, the License Agreement shall continue in full force
    and effect.

IN WITNESS WHEREOF, the parties hereto have caused their duly authorized 
representatives to execute and deliver this First Amendment as of the date
set forth above.

only for certain limited purposes. During the term of my employment and 
thereafter, I will hold Third Party Information in the strictest confidence and 
will not disclose or use Third Party Information except as permitted by the 
agreement between the Company and such third party, unless expressly authorized 
by an officer of the Company in writing.

     3.    Assignment of Inventions.
           ------------------------

           a.    I hereby assign to the Company all my right, title and interest
in and to any and all Inventions (and all Proprietary Rights with respect 
thereto) whether or not patentable

 
 
or registrable under copyright or similar statutes, made or conceived or reduced
to practice or learned by me, either alone or jointly with others, during the
period of and within the scope of my employment with the Company. I agree that 
all such Inventions are the sole property of the Company.

           b.    I hereby also assign to or as directed by the Company all my
right, title and interest in and to any and all Inventions, full title to which
is required to be in the United States by a contract between the Company and the
United States or any of its agencies.

           c.    I acknowledge that all original works of authorship which are
made by me (solely or jointly with others) within the scope of my employment and
which are protectable by copyright are "works made for hire," as that term is
defined in the United States Copyright Act (17 U.S.C., Section 101). Inventions
assigned to or as directed by the Company by this paragraph 3 are hereinafter
referred to as "Company Inventions."

     4. Enforcement of Proprietary Rights. I will assist the Company in every
        ---------------------------------
proper way to obtain and from time to time enforce United States and foreign
Proprietary Rights relating to Company Inventions in any and all countries. To
that end I will execute, verify and deliver such documents and perform such
other acts (including appearances as a witness) as the Company may reasonably
request for use in applying for, obtaining, perfecting, evidencing, sustaining
and enforcing such Proprietary Rights and the assignment thereof. In addition, I
will execute, verify and delivery assignments of such Proprietary Rights to the
Company or its designee. My obligation to assist the Company with respect to
Proprietary Rights relating to such Company Inventions in any and all countries
shall continue beyond the termination of my employment for a period of one year,
but the Company shall compensate me at a reasonable rate after my termination
for the time actually spent by me at the Company's request on such assistance.

     In the event the Company is unable for any reason, after reasonable effort,
to secure my signature on any document needed in connection with the actions 
specified in the preceding paragraph, I hereby irrevocably designate and appoint
the Company and its duly authorized officers and agents as my agent and attorney
in fact, to act for and in my behalf to execute, verify and file any such 
documents and to do all other lawfully permitted acts to further the purposes of
the preceding paragraph thereon with the same legal force and effect as if 
executed by me. I hereby waive and quit claim to the Company any and all claims,
of any nature whatsoever, which I now or may hereafter have for infringement of 
any Proprietary Rights assigned hereunder to the Company.

                                      -2- 

 
 
     5.    Obligation to Keep Company Informed. During the period of my 
           -----------------------------------
employment, I will promptly disclose to the Company fully and in writing and 
will hold in trust for the sole right and benefit of the Company any and all 
Inventions relating to the Company's business. In addition, after termination of
my employment, I will disclose a summary of all patent applications filed by me 
within one year after termination of employment.

     6.    Prior Inventions. Inventions, if any, patented or unpatented, which I
           ----------------
made prior to the commencement of my employment with the Company are excluded 
from the scope of this Agreement. To preclude any possible uncertainty, I have 
set forth on Exhibit A attached hereto a complete and exhaustive list of all 
inventions that I have, alone or jointly with others, conceived, developed or 
reduced to practice or caused to be conceived, developed or reduced to practice 
prior to the commencement of my employment with the Company, that I consider to
be my property or the property of third parties and that I wish to have excluded
from the scope of this Agreement. If disclosure of any such invention on Exhibit
A would cause me to violate any prior confidentiality agreement, I understand 
that I am not to list such inventions in Exhibit A, but am to inform the Company
that all such inventions have not been listed for that reason.

     7.    Additional Activities. I agree that during the period of my 
           ---------------------
full-time employment by the Company I will not, without the Company's express
written consent, engage in any employment or business activity other than for
the Company, and for the period of my employment by the Company and for one (1)
year after the date of termination of my employment by the Company, I will not
(i) induce any employee of the Company to leave the employ of the Company or
(ii) solicit the business of any client or customer on behalf of a competitor of
the Company (other than on behalf of the Company).

     8.    No Improper Use of Materials. During my employment by the Company I 
           ----------------------------
will not improperly use or disclose any confidential information or trade 
secrets, if any, of any former employers or any other person to whom I have an 
obligation of confidentiality, and I will not bring onto the premises of the 
Company any unpublished documents or any property belonging to any former 
employer or any other person to whom I have an obligation of confidentiality 
unless consented to in writing by that former employer or person.

     9.    No Conflicting Obligation. I represent that my performance of all the
           -------------------------
terms of this Agreement and as an employee of the Company does not and will not 
breach any agreement to keep in confidence information acquired by me in 
confidence or in trust prior to my employment by the Company. I have not entered
into, and I agree I will not enter into, any agreement either written or oral in
conflict herewith.

                                      -3-


 
 
     10.   Return of Company Documents. When I leave the employ of the Company, 
           ---------------------------
I will deliver to the Company any and all drawings, notes, memoranda, 
specifications, devices, formulas, molecules, cells and documents, together with
all copies thereof, and any other material containing or disclosing any Company 
Inventions, Third Party Information or Proprietary Information of the Company.

     11.   Legal and Equitable Remedies. Because my services are personal and 
           ----------------------------
unique and because I may have access to and become acquainted with the 
Proprietary Information of the Company, the Company shall have the right to 
enforce this Agreement and any of its provisions by injunction, specific 
performance or other equitable relief, without bond, without prejudice to any 
other rights and remedies that the Company may have for a breach of this 
Agreement.

     12.   Notices. Any notices required or permitted hereunder shall be given 
           -------
to the appropriate party at the address specified below or at such other address
as the party shall specify in writing. Such notice shall be deemed given upon 
personal delivery to the appropriate address or if sent by certified or 
registered mail, three days after the date of mailing.

                             EMPLOYMENT AGREEMENT

This Employment Agreement (the "Agreement") is entered into as of June 19,
1992, by and between AASTROM BIOSCIENCES, INC., a Michigan corporation 
("Employer") and JAMES MALUTA ("Employee").

     NOW, THEREFORE, the parties agree as follows:
   
     1.  EMPLOYMENT   Employer hereby engages Employee, and Employee hereby 
accepts such engagement, upon the terms and conditions set forth herein.

     2.  DUTIES   Employee is engaged as Vice President, Product Development.  
Employee shall perform faithfully and diligently the duties customarily 
performed by persons in the position for which employee is engaged, together 
with such other reasonable and appropriate duties as Employer shall designate 
from time to time.  Employee shall devote Employee's full business time and
efforts to the rendition of such services and to the performance of such duties.
As a full-time employee of Employer, Employee shall not be entitled to provide
consulting services or other business or scientific services to any other party,
without the prior written consent of Employer.

     3.  COMPENSATION

         3.1 BASE SALARY  During the term of this Agreement, as compensation for
the proper and satisfactory performance of all duties to be performed by
Employee hereunder, Employer shall pay Employee a salary of $90,000 per year,
payable in arrears in equal bi-weekly installments, less required deductions for
state and federal withholding tax, Social Security and all other employee taxes
and payroll deductions. The base salary shall be subject to review and
adjustment on an annual basis.

         3.2  BONUS COMPENSATION  Employee may receive bonus in the form of a
stock option, stock, or cash, the amount and timing of which shall be determined
in the sole discretion of the Board of Directors of Employer.

     4.  TERM

         4.1  COMMENCEMENT  The employment relationship pursuant to this
Agreement shall commence no later than August 1, 1992.

         4.2  TERMINATION AT WILL  Although Employer and Employee anticipate a
long and mutually rewarding employment relationship, either party may terminate
this Agreement, without cause, upon fourteen (14) days' prior written notice
delivered to the other. It is expressly understood and agreed that the
employment relationship is "at will", and with no agreement for employment for
any specified term, and with no agreement for employment for so long as Employee
performs satisfactorily. Provided, however, before Employer


 
exercises this right of termination at will, Employer shall first either (i)
discuss with Employee the needs of Employer and why Employee no longer meets
those needs, or (ii) discuss with Employee any concerns or dissatisfactions
which Employer has with Employee's performance, and give to Employee a
reasonable opportunity to remedy those concerns or dissatisfactions, to the
reasonable satisfaction of Employer.

         4.3  TERMINATION FOR CAUSE   Either party may terminate this employment
relationship immediately upon notice to the other party in the event of any good
cause, such as a default, dishonesty, neglect of duties, failure to perform  by
the other party, or death or disability of Employee.

         4.4  PAYMENT OF COMPENSATION UPON TERMINATION   Upon termination for
cause, Employee shall be entitled to the compensation set forth as "base salary"
herein, prorated to the effective date of such termination as full compensation
for any and all claims of Employee under this Agreement.

     5.  FRINGE BENEFITS

         5.1 CUSTOMARY FRINGE BENEFITS  Employee shall be entitled to such
fringe benefits as Employer customarily makes available to employees of Employer
engaged in the same or similar position as Employee ("Fringe Benefits"). Such
Fringe Benefits may include vacation leave, sick leave, and health insurance
coverage. Employer reserves the right to change the Fringe Benefits on a
prospective basis, at any time, effective upon delivery of written notice to

              6.1.1  Invention Defined. As used herein "Invention" means

copyrightable or not, including but not limited to processes, methods, formulas,
techniques, devices, designs, programs (including computer programs), computer
graphics, apparatus, products, as well as improvements thereof or know-how

industry.

         6.2  INVENTIONS
 
              6.2.1 Disclosure. Employee shall disclose promptly to Employer
each Invention, whether or not reduced to practice, which is conceived or
learned by Employee (either alone or jointly with others) during the term of his
employment with Employer. Employee shall disclose in confidence to Employer all
patent applications filed by or on behalf of Employee during the term of his
employment and for a period of three (3) years thereafter. Any disclosure of an
Invention, or any patent application, made within one (1) year after termination
of employment shall be presumed to relate to an Invention made during Employee's
term of Employment with Employer, unless Employee clearly proves otherwise.

              6.2.2 Employer Property; Assignment. Employee acknowledges and
agrees that all Inventions which are discovered, conceived, developed, made,
produced or prepared by Employee (alone or in conjunction with others) during
the duration of Employee's employment with Employer shall be the sole property
of Employer. Said property rights of Employer include without limitation all
domestic and foreign patent rights, rights of registration or other protection
under the patent and copyright laws, and all other rights pertaining to the
Inventions. Employee further agrees that all services, products and Inventions
that directly or indirectly result from engagement with Company shall be deemed
"works for hire" as that term is defined in Title 17 of the United States Codes,
and accordingly all rights associated therewith shall vest in the Company.
Notwithstanding the foregoing, Employee hereby assigns to Employer all of
Employee's right, title and interest in any such services, products and
Inventions, in the event any such services, products and Inventions shall be
determined not to constitute "works for hire."

              6.2.3 Exclusion Notice. The Assignment by Employee of Inventions
under this Agreement does not apply to any Inventions which are owned or
controlled by Employee prior to the commencement of employment of Employee by
Employer (all of which are set forth on Exhibit "A" hereto). Additionally,
Employee is not required to assign an idea or invention where the invention or
idea meets all of the following criteria; namely if the invention or idea: (i)
was created or conceived without the use of any of Employer's equipment,
supplies, facilities, or trade secret information, and (ii) was developed
entirely on Employee's own time, and (iii) does not relate to the business of
Employer, and (iv) does not relate to Employer's actual or demonstrably
anticipated research or development, and (v) does not result from any work
performed by Employee for Employer.

after termination of this Agreement (and with reasonable compensation paid by
Employer to Employee after termination), Employee agrees to assist the Employer

any documents and assignments determined to be necessary or convenient for use
in applying for, obtaining, registering and enforcing patent or copyright
protection involving any of the Inventions. Employee hereby irrevocably appoints
Employer, and its duly authorized officers and agents, as Employee's agent and
attorney-in-fact, to act for and in behalf of Employee in filing all patent
applications, applications for copyright protection and registration,
amendments, renewals, and all other appropriate documents in any way related to
the Inventions described in Section 6.2.2.

         6.3  TRADE SECRETS

developed by Employee alone or in conjunction with others or otherwise, shall be
and are the property of Employer.

              6.3.2  Covenant Not to Divulge Trade Secrets. Employee
acknowledges and agrees that Employer is entitled to prevent the disclosure of
Trade Secrets of Employer. As a portion of the consideration for the employment
of Employee and for the compensation being paid to Employee by Employer,

thereafter to hold in strictest confidence, and not to use, disclose or allow to
be disclosed to any person, firm, or corporation, Trade Secrets of Employer,
including Trade Secrets developed by Employee, other than disclosures to persons
engaged by Employer to further the business of Employer, and other than use in
the pursuit of the business of Employer.

and warrants that if Employee has any confidential information belonging to
others, Employee will not use or disclose to Employer any such information or
documents. Employee represents that his employment with Employer will not
require him to violate any obligation to or confidence with any other party.

         6.4  NO ADVERSE USE  Employee will not at any time use Employer's Trade
Secrets or Inventions in any manner which may directly or indirectly have an
adverse effect upon Employer's business, nor will Employee perform any acts
which would tend to reduce Employer's proprietary value in Employer's Trade
Secrets or Inventions.


 
         6.5  RETURN OF MATERIALS AT TERMINATION  In the event of any
termination of Employee's employment, Employee will promptly deliver to Employer
all materials, property, documents, data, and other information belonging to
Employer or pertaining to Trade Secrets or Inventions. Employee shall not take

institute and prosecute proceedings in any court of competent jurisdiction,
either in law or in equity, to enjoin Employee from violating any of the terms
of this Section 6, to enforce the specific performance by Employee of any of the
terms of this Section 6, and to obtain damages for any of them, but nothing
herein contained shall be construed to prevent such remedy or combination of
remedies as Employer may elect to invoke. The failure of Employer to promptly
institute legal action upon any breach of this Section 6 shall not constitute a
waiver of that or any other breach hereof.

     7.  COVENANT NOT TO COMPETE   Employee agrees that, during Employee's
employment, Employee will not directly or indirectly compete with Employer in
any way, and that Employee will not act as an officer, director, employee,
consultant, shareholder, lender or agent of any other entity which is engaged in
any business of the same nature as, or in competition with, the business in
which Employer is now engaged, or in which Employer becomes engaged during the

which is similar to Employer's science or technology.

              6.1.1  Invention Defined.  As used herein "Invention" means
inventions, discoveries, concepts, and ideas, whether patentable or
copyrightable or not, including but not limited to processes, methods, formulas,
techniques, materials, devices, designs, programs (including computer programs),
computer graphics, apparatus, products, as well as improvements thereof or know-
how related thereto, relating to any present or anticipated business or
activities of Employer.

processes or services, including documents and information relating to
Inventions, and to the research, development, engineering or manufacture of
Inventions, and to Employer's purchasing, customer or supplier lists, which


 
documents or information have been disclosed to Employee or known to Employee as

developed by Employee), which is not generally known in the relevant trade or
industry.

     6.2  INVENTIONS
 
          6.2.1  Disclosure.  Employee shall disclose promptly to Employer each
Invention, whether or not reduced to practice, which is conceived or learned by
Employee (either alone or jointly with others) during the term of his employment
with Employer. Employee shall disclose in confidence to Employer all patent
applications filed by or on behalf of Employee during the term of his employment
and for a period of three (3) years thereafter. Any disclosure of an Invention,

duration of Employee's employment with Employer shall be the sole property of
Employer. Said property rights of Employer include without limitation all
domestic and foreign patent rights, rights of registration or other protection
under the patent and copyright laws, and all other rights pertaining to the
Inventions. Employee further agrees that all services, products and Inventions
that directly or indirectly result from engagement with Company shall be deemed
"works for hire" as that term is defined in Title 17 of the United States Codes,
and accordingly all rights associated therewith shall vest in the Company.
Notwithstanding the foregoing, Employee hereby assigns to Employer all of
Employee's right, title and interest in any such services, products and
Inventions, in the event any such services, products and Inventions shall be
determined not to constitute "works for hire."

          6.2.3  Exclusion Notice.  The Assignment by Employee of Inventions
under this Agreement does not apply to any Inventions which are owned or
controlled by Employee prior to the commencement of employment of Employee by
Employer (all of which are set forth on Exhibit "A" hereto). Additionally,
Employee is not required to assign an idea or invention where the invention or
idea meets all of the following criteria; namely if the invention or idea: (i)
was created or conceived without the use of any of Employer's equipment,
supplies, facilities, or trade secret information, and (ii) was developed
entirely on Employee's own time, and (iii) does not relate to the business of
Employer, and (iv) does not relate to Employer's actual or demonstrably
anticipated research or development, and (v) does not result from any work
performed by Employee for Employer.

          6.2.4  Patents and Copyrights; Attorney-in Fact.  Both before and
after termination of this Agreement (and with reasonable compensation paid 


 
by Employer to Employee after termination), Employee agrees to assist the
Employer to apply for, obtain and enforce patents on, and to apply for, obtain
and enforce copyright protection and registration of, the Inventions described
in Section 6.2.2 in any and all countries. To that end, Employee shall (at

any documents and assignments determined to be necessary or convenient for use
in applying for, obtaining, registering and enforcing patent or copyright
protection involving any of the Inventions. Employee hereby irrevocably appoints
Employer, and its duly authorized officers and agents, as Employee's agent and
attorney-in-fact, to act for and in behalf of Employee in filing all patent
applications, applications for copyright protection and registration,
amendments, renewals, and all other appropriate documents in any way related to
the Inventions described in Section 6.2.2.

     6.3  TRADE SECRETS

          6.3.1  Acknowledgment of Proprietary Interest.  Employee recognizes
the proprietary interest of Employer in any Trade Secrets of Employer. Employee
acknowledges and agrees that any and all Trade Secrets of Employer, whether
developed by Employee alone or in conjunction with others or otherwise, shall be
and are the property of Employer.

          6.3.2  Covenant Not to Divulge Trade Secrets.  Employee acknowledges
and agrees that Employer is entitled to prevent the disclosure of Trade Secrets
of Employer. As a portion of the consideration for the employment of Employee
and for the compensation being paid to Employee by Employer, Employee agrees at
all times during the term of the employment by Employer and thereafter to hold
in strictest confidence, and not to use, disclose or allow to be disclosed to
any person, firm, or corporation, Trade Secrets of Employer, including Trade
Secrets developed by Employee, other than disclosures to persons engaged by
Employer to further the business of Employer, and other than use in the pursuit
of the business of Employer.

          6.3.3  Confidential Information of Others.  Employee represents and
warrants that if Employee has any confidential information belonging to others,
Employee will not use or disclose to Employer any such information or documents.
Employee represents that his employment with Employer will not require him to
violate any obligation to or confidence with any other party.

     6.4  NO ADVERSE USE   Employee will not at any time use Employer's Trade
Secrets or Inventions in any manner which may directly or indirectly have an
adverse effect upon Employer's business, nor will Employee perform any acts
which would tend to reduce Employer's proprietary value in Employer's Trade
Secrets or Inventions.

     6.5  RETURN OF MATERIALS AT TERMINATION   In the event of any termination
of Employee's employment, Employee will promptly deliver to Employer all
materials, property, documents, data, and other information 


 
belonging to Employer or pertaining to Trade Secrets or Inventions. Employee
shall not take any materials, property, documents or other information, or any
reproduction or excerpt thereof, belonging to Employer or containing or
pertaining to any Trade Secrets or Inventions.

     6.6  REMEDIES UPON BREACH  In the event of any breach by Employee of the
provision in this Section 6, Employer shall be entitled, if it so elects, to
institute and prosecute proceedings in any court of competent jurisdiction,
either in law or in equity, to enjoin Employee from violating any of the terms
of this Section 6,  to enforce the specific performance by Employee of any of
the terms of this Section 6, and to obtain damages for any of them, but nothing
herein contained shall be construed to prevent such remedy or combination of
remedies as Employer may elect to invoke.  The failure of Employer to promptly
institute legal action upon any breach of this Section 6 shall not constitute a
waiver of that or any other breach hereof.

     7.  COVENANT NOT TO COMPETE  Employee agrees that, during Employee's
employment, Employee will not directly or indirectly compete with Employer in
any way, and that Employee will not act as an officer, director, employee,
consultant, shareholder, lender or agent of any other entity which is engaged in
any business of the same nature as, or in competition with, the business in
which Employer is now engaged, or in which Employer becomes engaged during the
term of Employee's employment, or which is involved in science or technology
which is similar to Employer's science or technology.

     8.  GENERAL PROVISIONS

under this Agreement shall inure to the benefit of and shall be binding upon the
successors and assigns of Employer. Employee shall not be entitled to assign any
of Employee's rights or obligations under this Agreement.


 
         8.5  WAIVER    Either party's failure to enforce any provision of this
Agreement shall not in any way be construed as a waiver of any such provision,
or prevent that party thereafter from enforcing each and every other provision
of this Agreement.

         8.6  SEVERABLE PROVISIONS    The provisions of this Agreement are
severable, and if any or more provisions may be determined to be judicially
unenforceable, in whole or in part, the remaining provisions shall nevertheless

                             EMPLOYMENT AGREEMENT

This Employment Agreement (the "Agreement") is entered into as of 26 October 
1995, by and between AASTROM BIOSCIENCES, INC., a Michigan corporation 
("Employer") and ALAN K. SMITH ("Employee").

     NOW, THEREFORE, the parties agree as follows:

     1.  EMPLOYMENT   Employer hereby engages Employee, and Employee hereby 
accepts such engagement, upon the terms and conditions set forth herein.

     2.  DUTIES  Employee is engaged as a Vice President Research. Employee
shall perform faithfully and diligently the duties customarily performed by
persons in the position for which employee is engaged, together with such other
reasonable and appropriate duties as Employer shall designate from time to time.
Employee shall devote Employee's full business time and efforts to the rendition
of such services and to the performance of such duties. As a full-time employee
of Employer, Employee shall not be entitled to provide consulting services or
other business or scientific services to any other party, without the prior
written consent of Employer.

     3.  COMPENSATION

         3.1  BASE SALARY  During the term of this Agreement, as compensation
for the proper and satisfactory performance of all duties to be performed by
Employee hereunder, Employer shall pay Employee at an annual salary rate of One
Hundred Twenty Two Thousand Five Hundred Dollars ($122,500), payable in arrears
in equal bi-weekly installments, less required deductions for state and federal
withholding tax, Social Security and all other employee taxes and payroll
deductions. The base salary shall be subject to review and adjustment on an
annual basis.

     4.  TERM

         4.1  COMMENCEMENT  The employment relationship pursuant to this
Agreement shall commence November 13, 1995.

         4.2  TERMINATION AT WILL  Although Employer and Employee anticipate a
long and mutually rewarding employment relationship, either party may terminate
this Agreement, without cause, upon fourteen (14) days' prior written notice
delivered to the other.  It is expressly understood and agreed that the
employment relationship is "at will", and with no agreement for employment for
any specified term, and with no agreement for employment for so long as Employee
performs satisfactorily.  Provided, however, before Employer exercises this
right of termination at will, Employer shall first either (i) discuss with
Employee the needs of Employer and why Employee no longer meets those needs, or
(ii) discuss with Employee any concerns or dissatisfactions which


 
Employer has with Employee's performance, and give to Employee a reasonable
opportunity to remedy those concerns or dissatisfactions, to the reasonable
satisfaction of Employer. Should, for some reason, Employee's involuntary
termination without cause be necessary, severance compensation equal to four (4)
months' salary will be paid, along with compensation for any accumulated
vacation time.

         4.3  TERMINATION FOR CAUSE  Either party may terminate this employment
relationship immediately upon notice to the other party in the event of any good
cause, such as a default, dishonesty, neglect of duties, failure to perform  by
the other party, or death or disability of Employee.

         4.4  PAYMENT OF COMPENSATION UPON TERMINATION  Upon termination for
cause, Employee shall be entitled to the compensation set forth as "base salary"
herein, prorated to the effective date of such termination as full compensation
for any and all claims of Employee under this Agreement.

     5.  FRINGE BENEFITS

         5.1  CUSTOMARY FRINGE BENEFITS  Employee shall be entitled to such
fringe benefits as Employer customarily makes available to employees of Employer
engaged in the same or similar position as Employee ("Fringe Benefits"). Such
Fringe Benefits may include vacation leave, sick leave, and health insurance
coverage. Employer reserves the right to change the Fringe Benefits on a
prospective basis, at any time, effective upon delivery of written notice to
Employee.

         5.2  ACCUMULATION  Employee shall not earn and accumulate unused
vacation in excess of Fifteen (15) days. Employee shall not earn and accumulate
sick leave or other Fringe Benefits in excess of an unused amount equal to twice
the amount earned for one year. Further, Employee shall not be entitled to
receive payments in lieu of said Fringe Benefits, other than for unused vacation
leave earned and accumulated at the time the employment relationship terminates.

     6.  INVENTIONS, TRADE SECRETS AND CONFIDENTIALITY

         6.1  DEFINITIONS

              6.1.1  Invention Defined.  As used herein "Invention" means
inventions, discoveries, concepts, and ideas, whether patentable or
copyrightable or not, including but not limited to processes, methods, formulas,
techniques, materials, devices, designs, programs (including computer programs),
computer graphics, apparatus, products, as well as improvements thereof or know-
how related thereto, relating to any present or anticipated business or
activities of Employer.

              6.1.2  Trade Secret Defined.  As used herein "Trade Secret" means,
without limitation, any document or information relating to Employer's


 
products, processes or services, including documents and information relating to
Inventions, and to the research, development, engineering or manufacture of
Inventions, and to Employer's purchasing, customer or supplier lists, which
documents or information have been disclosed to Employee or known to Employee as
a consequence of or through Employee's employment by Employer (including
documents, information or Inventions conceived, originated, discovered or
developed by Employee), which is not generally known in the relevant trade or
industry.

         6.2  INVENTIONS
 
              6.2.1  Disclosure.  Employee shall disclose promptly to Employer
each Invention, whether or not reduced to practice, which is conceived or
learned by Employee (either alone or jointly with others) during the term of his
employment with Employer. Employee shall disclose in confidence to Employer all
patent applications filed by or on behalf of Employee during the term of his
employment and for a period of three (3) years thereafter. Any disclosure of an
Invention, or any patent application, made within one (1) year after termination
of employment shall be presumed to relate to an Invention made during Employee's
term of Employment with Employer, unless Employee clearly proves otherwise .

              6.2.2  Employer Property; Assignment.  Employee acknowledges and
agrees that all Inventions which are discovered, conceived, developed, made,
produced or prepared by Employee (alone or in conjunction with others) during
the duration of Employee's employment with Employer shall be the sole property
of Employer. Said property rights of Employer include without limitation all
domestic and foreign patent rights, rights of registration or other protection
under the patent and copyright laws, and all other rights pertaining to the
Inventions. Employee further agrees that all services, products and Inventions
that directly or indirectly result from engagement with Company shall be deemed
"works for hire" as that term is defined in Title 17 of the United States Codes,
and accordingly all rights associated therewith shall vest in the Company.
Notwithstanding the foregoing, Employee hereby assigns to Employer all of
Employee's right, title and interest in any such services, products and
Inventions, in the event any such services, products and Inventions shall be
determined not to constitute "works for hire."

              6.2.3  Exclusion Notice.  The Assignment by Employee of Inventions
under this Agreement does not apply to any Inventions which are owned or
controlled by Employee prior to the commencement of employment of Employee by
Employer (all of which are set forth on Exhibit "A" hereto). Additionally,
Employee is not required to assign an idea or invention where the invention or
idea meets all of the following criteria; namely if the invention or idea: (i)
was created or conceived without the use of any of Employer's equipment,
supplies, facilities, or trade secret information, and (ii) was developed
entirely on Employee's own time, and (iii) does not relate to the business of
Employer, and (iv) does not relate to Employer's actual or demonstrably
anticipated research or development, and (v) does not result from any work
performed by Employee for Employer.


 
              6.2.4  Patents and Copyrights; Attorney-in-Fact.  Both before and
after termination of this Agreement (and with reasonable compensation paid by
Employer to Employee after termination), Employee agrees to assist the Employer
to apply for, obtain and enforce patents on, and to apply for, obtain and
enforce copyright protection and registration of, the Inventions described in
Section 6.2.2 in any and all countries. To that end, Employee shall (at
Employer's request) without limitation, testify in any proceeding, and execute
any documents and assignments determined to be necessary or convenient for use
in applying for, obtaining, registering and enforcing patent or copyright
protection involving any of the Inventions. Employee hereby irrevocably appoints
Employer, and its duly authorized officers and agents, as Employee's agent and
attorney-in-fact, to act for and in behalf of Employee in filing all patent
applications, applications for copyright protection and registration,
amendments, renewals, and all other appropriate documents in any way related to
the Inventions described in Section 6.2.2.

         6.3  TRADE SECRETS

              6.3.1  Acknowledgment of Proprietary Interest.  Employee
recognizes the proprietary interest of Employer in any Trade Secrets of
Employer. Employee acknowledges and agrees that any and all Trade Secrets of
Employer, whether developed by Employee alone or in conjunction with others or
otherwise, shall be and are the property of Employer.

              6.3.2  Covenant Not to Divulge Trade Secrets.  Employee
acknowledges and agrees that Employer is entitled to prevent the disclosure of
Trade Secrets of Employer. As a portion of the consideration for the employment
of Employee and for the compensation being paid to Employee by Employer,
Employee agrees at all times during the term of the employment by Employer and
thereafter to hold in strictest confidence, and not to use, disclose or allow to
be disclosed to any person, firm, or corporation, Trade Secrets of Employer,
including Trade Secrets developed by Employee, other than disclosures to persons

               them. Consultant understands and agrees that Company will not pay
               or withhold from the compensation paid to Consultant pursuant to
               this Agreement any sums customarily paid or withheld for or on

               8.1  Acknowledgment of Proprietary Interest.  Consultant
                    recognizes the proprietary interest of Company in any Trade
                    Secrets of Company.  As used herein, the term "Trade
                    Secrets" includes all of Company's confidential or
                    proprietary information, including without limitation any
                    confidential information of Company encompassed in any
                    reports, investigations, experiments, research or
                    developmental work, inventions, technology, experimental
                    work, work in progress, drawings, designs, plans, proposals,
                    codes, marketing and sales programs, financial projections,
                    cost summaries, pricing formula, and all concepts or ideas,
                    materials or information related to the business, products
                    or sales of the Company or the Company's customers which has
                    not previously been released to the public at large by duly
                    authorized representatives of the Company, whether or not
                    such information would be enforceable as a trade secret or
                    the copying of which would be enjoined or restrained by a
                    court as constituting unfair competition.  Consultant
                    acknowledges and agrees that any and all Trade Secrets of
                    Company, learned by Consultant during the course of the
                    engagement by Company or otherwise, whether developed by
                    Consultant alone or in conjunction with others or otherwise,
                    shall be and is the property of Company.

 
               8.2  Ownership of Work.  All inventions, patents, discoveries,
                    reports and ideas arising from Consultant's services to
                    Company hereunder shall be the sole property of Company and
                    shall be Company's Trade Secrets.  Consultant agrees to
                    assign and hereby assigns to Company, its successors or
                    assigns, all Consultant's right, title and interest in and
                    to said Trade Secrets, inventions or discoveries and any
                    patent application or letters parent thereon.  Consultant
                    agrees to reasonably cooperate with Company, at no expense
                    to Consultant, to effect such ownership rights.  Consultant
                    hereby irrevocably appoints Company and its officers as his
                    agent and attorney-in-fact to execute and file any patent
                    applications and related documents pertaining to said Trade
                    Secrets if he is deemed to be an "inventor" of an invention
                    which is part of Company's Trade Secrets.

               8.3  Publication.  Any publications and reports by Consultant
                    concerning Consultant's scientific work may be released in
                    accordance with Employer's customary practices, policies and
                    agreements.  Provided, however, Consultant shall not publish
                    any manuscript or other document, solely or in co-authorship
                    with others, pertaining to Company's Trade Secrets or
                    Company's other information attributable to any project
                    undertaken by Company, without Company's prior written
                    consent.

               8.4  Covenant Not to Divulge Trade Secrets.  Consultant
                    acknowledges and agrees that Company is entitled to prevent
                    the disclosure of Trade Secrets of Company.  As a portion of
                    the consideration for the appointment of Consultant and for
                    the compensation being paid to Consultant by company,
                    Consultant agrees at all times during the term of the
                    engagement with Company and thereafter to hold in strictest
                    confidence, and not to disclose or allow to be disclosed to
                    any person, firm or corporation, other than to persons
                    engaged by Company to further the business of Company, and
                    not to use except in the pursuit of the business of Company,
                    Trade Secrets of Company, without the prior written consent
                    of Company, including Trade Secrets developed by Consultant.

 
               8.5  Return of Materials at Termination.  In the event of any
                    termination of Consultant's appointment, with or without
                    cause, Consultant will promptly deliver to Company all
                    materials, property, documents or other information, or any
                    reproduction or excerpt thereof, belonging to Company or
                    containing or pertaining to any Trade Secrets.

               8.6  Remedies Upon Breach.  In the event of any breach of this
                    Agreement by Consultant, Company shall be entitled, if it so
                    elects, to institute and prosecute proceedings in any court
                    of competent jurisdiction, either in law or in equity, to
                    enjoin Consultant from violating any of the terms of this
                    Agreement, to enforce the specific performance by Consultant
                    of any of the terms of this Agreement, and to obtain
                    damages, or any of them, but nothing herein contained shall
                    be construed to prevent such remedy or combination of
                    remedies as Company may elect to invoke.  The failure of
                    Company to promptly institute legal action upon any breach
                    of this Agreement shall not constitute a waiver of that or
                    any other breach hereof.

          accordance with the procedures detailed in the Protocol.

          Invention to Aastrom on such different terms in accordance with the
          first right refusal herein. The Institution and Principal Investigator

XII.  PUBLICATION RIGHTS

      At least thirty (30) days prior to submission for publication, the
      Institution agrees to provide Aastrom a final draft of any manuscript
      describing the results obtained by the Institution from the Study. Aastrom
      shall be permitted to advise as to the implications of such manuscripts
      upon patentability of any inventions or the potential effects on
      commercialization. The Institution shall, upon Aastrom's request, delete
      any of Aastrom's Confidential Information and shall consider all
      reasonable editorial suggestions based on sound scientific and clinical
      judgment, Aastrom acknowledges that Institution shall have the final
      authority to determine the scope and content of any publication, provided
      that such authority shall be exercised with reasonable regard for the
      commercial interests of Aastrom. Subject to Aastrom's right to delete such
      Confidential Information and to propose mutually agreeable modification of
      such manuscripts, the Institution shall have the right to submit the
      manuscript for publication. However, if Aastrom determines that any
      invention disclosed therein is patentable and that a patent application
      should be filed on such invention, Aastrom shall notify the Institution in
      writing and the Institution shall postpone publication for a period not to
      exceed sixty (60) days from said notice (unless otherwise mutually agreed
      in writing) to provide time for patent applications to be filed.

REVISED AUGUST 5, 1996


 
1.0  OBJECTIVES

     1.1  To assess the safety of the mixture of early-, mid-, and late-stage
          bone marrow-derived mononuclear cells produced in the Aastrom Cell
          Production System (CPS) when infused into patients with breast
          cancer.

     1.2  To determine the biological effect in terms of hematopoietic recovery
          after infusion of ex vivo-produced hematopoietic cells following high
          dose chemotherapy as treatment of patients with breast cancer.

     1.3  To record the clinical disease related outcome in these patients with
          advanced breast cancer- clinical tumor response, duration of
          responses, and disease free duration post-high dose chemotherapy.

2.0  BACKGROUND

     2.1  Ex Vivo Expansion: Current Status June 1996
          Autologous bone marrow transplantation has been increasingly employed
          as supportive therapy for subjects undergoing high dose chemotherapy
          or chemoradiotherapy for malignant diseases, including lymphoma,
          leukemia, and breast cancer. Breast cancer is now the most frequent
          indication for autologous bone marrow or blood progenitor cell
          transplantation.

          Despite the use of cytokines such as granulocyte-macrophage colony-
          stimulating factor (GM-CSF) and granulocyte colony-stimulating factor
          (G-CSF) following bone marrow reinfusion, there is an obligate period
          of profound pancytopenia lasting 1-3 weeks, and delayed engraftment
          can occur, resulting in morbidity or mortality.

          The safety, comfort, and cost of stem- and progenitor cell harvest are
          also concerns. The standard techniques employed to harvest bone marrow
          involves obtaining 500-1500 mL of bone marrow from the marrow donor,
          usually under general anesthesia. In addition to the discomfort caused
          by the hundreds of marrow aspirates performed, donors are subject to
          the risks of general anesthesia. Finally, the bone marrow harvest
          procedure is expensive. Alternatively, stem- and progenitor cells can
          be collected from peripheral blood by apheresis, but this requires
          chemotherapy and/or growth factors for mobilization and multiple
          collections are generally necessary, which are costly.

          Recently, novel technology has been developed to produce stem- and
          progenitor cell populations in vitro, commonly referred to as ex vivo
          expansion. Hematopoietic cell expansions achieved with this technology
          are based upon the principles of continuous perfusion culture, a
          bioengineered metabolic environment, augmented by hematopoietic growth
          factors. Through this technology, a small bone marrow or peripheral
          blood mononuclear cell population can be perfused ex vivo so that
          total cell numbers, colony forming units (CFU-S) and long term culture
          initiating cells (LTC-ICs) increase up to 20 fold (1-17). In a
          preliminary study, Brugger et al recently reported that



 
expanded cells alone can reconstitute hematopoiesis after high dose chemotherapy
(18).

Important differences exist among approaches, systems and devices used for ex
vivo expansion. This study utilizes the Aastrom CPS, which includes a cell
culture device and a biological environment designed to allow the establishment
of a stromal adherent layer, using constant perfusion with medium, and
relatively low concentrations of hematopoietic growth factors. Preliminary
studies at MD Anderson Cancer Center (DM94-127), using transplantation of ex
vivo-produced cells prepared with this system, in combination with a standard
autologous marrow transplant, indicate that ex vivo expansion can be performed
reliably and reproducibly, and that no toxicity occurs with intravenous infusion
(19). Ten patients, age 18-60 years with breast carcinoma, were entered into a
study transplanting bone marrow plus ex vivo-produced cells. Bone marrow was
harvested, collecting greater than 2 x 10/8/ nucleated cells/kg and greater than
0.5 x 10/6/ CD34+ cells/kg. Twelve days prior to the planned bone marrow
transplant, 2.25 x 10/8/ mononuclear cells were inoculated into a cell culture
device, part of the CPS, and continuously perfused with medium containing
PIXY321 (5 ng/mi), Epo (0.1 U/ml) and hydrocortisone (5 x 10-6 M). The expansion
reproducibly increased total nucleated cells, CFU-GM, and long term culture
initiating cells (LTC-IC). Patients received Cyclophosphamide 2.0 g/m2/d:
Thiotepa 240 mg/mi/d: BCNU 150 Mg/M2/d. Days -7, -6, -5, with reinfusion of the
cryopreserved bone marrow on Day 0 plus the ex vivo-produced cells four hours
later. No toxicity was observed from the expanded cell infusion. Nadir WBC was
less than 0.1/ul. All patients engrafted within narrow time ranges, with median
recovery of WBC greater than 200/ul on Day 8 (range 7-8) granulocytes greater
than 500/ul on Day 11 (range 10-13) and platelets greater than 25,000/ul on Day
16 (range 13-21) and greater than 50,000 on Day 20 (range 18-27). A median of 4
(range 1-9) platelet and 4 (range 2-9) RBC transfusions were administered. No
grade greater than 2 toxicity occurred from the chemotherapy or bone marrow
infusions. Four patients had infections unrelated to the infusion of the cells
produced in the CPS. These data compare favorably with 29 historical controls
receiving the same chemotherapy and autoBMT without cell expansion, in which
granulocytes recovered to greater than 500 on Day 11 (range 7-29) and platelets
to greater than 25,000 and greater than 50,000 on Days 24 (range 9-78) and 28
(range 9-147), respectively.

A potential advantage of collecting a relatively small marrow inoculum is that 
the number of contaminating malignant cells is reduced: additionally, growth of 
breast cancer cells is not stimulated under these expansion conditions (Brugger 
et al).

Application of this technology to autologous bone marrow and peripheral stem 
cells transplant offers a potentially attractive means to increase the efficacy 
and safety of autologous transplantation, while reducing its complexity and 
cost. In particular, this technology could eliminate the need for operative bone
marrow 

 
          harvests, produce more rapid recovery of hematopoiesis post-
          transplant, reduce the length of post-transplant hospitalization, and
          could increase the purity of the stem- and progenitor cells
          transfused. In addition, the inclusion of cytokine-primed progenitors
          could result in accelerated hematopoietic recoveries.

2.2  Previous Pre-Clinical Research

          During hematopoietic expansion culture, total cell numbers increase 8
          to 11-fold over 12 days. This includes nonadherent, loosely adherent,
          and tightly adherent cells. Over 80% of the nucleated cells are
          viable, as shown by exclusion of propidium iodine stain (4) or Trypan
          blue dye. These cells have the morphological distribution of normal
          bone marrow cells, including blast cells and maturing granulocyte
          precursors, maturing erythroid cells, monocytes and macrophages.

          These expanded cells also show typical immunophenotype characteristics
          of normal granulocyte, erythroid, monocyte/macrophage megakaryocytic,
          and blast cells (5). Cell surface antigens identified using this
          technique include CD3, CD11b, CD15, CD20, CD33, CD71, and glycophorin
          A. While there are minor variations in staining patterns from sample
          to sample, the expanded cells are typically less than 3% CD3-.20-50%
          CD11b-, less than 1% CD19-, and 40-70% CD71-. The frequency of mature
          T and B lymphocytes in the expanded cell population is significantly
          reduced.

          As shown in the experiments summarized in the Table below, it was
          shown by Aastrom that varying the standard growth factor combination
          (IL-3-GM-CSF or PIXY321, Epo, SCF and flt3L) had a direct effect on
          the productivity of cells in the CPS, but the relative cell mixture
          composition remained substantially similar. These data were obtained
          in 36-well plate studies. This finding provided the original
          justification for selecting the growth factor combination (Epo -
          PIXY321 - flt3L) for this study to yield the desired relative
          composition and mixture of early-, mid- and late-stage cells produced
          in the pre-clinical experiments.

/2/LTC-IC were not evaluated, but in these conditions, 24 week CFU-GM producing cultures were obtained, representing an LTC-IC proxy. Aastrom has projected, based on this pre-clinical research, that clinical-size CPSs are expected to yield a mean of 3.0 x 10/9/ cells, 17.7 x 10/6/ CFU-GM and 6.4 x 10/5/ LTC-IC per patient in this proposed clinical feasibility trial, and set the expected minimum per-patient cell yield from the CPS at 1.6 x 10/9/ total nucleated cells and 7.0 x 10/10/ CFU-GM. In an average 70 kg patient, this translates to a dose of 2 x 10/5/ CFU-GM/kg. The clinically standard ABMT engraving dose is reported to be 1 x 10/5/ CFU-GM/kg. Therefore, using the cell dose and the CFU-GM content in the cells produced in the CPS as a key progenitor marker, along with the reliable presence of early stage cells (e.g., LTC-IC, CD34-lin-), there is an expectation that the CPS-produced cells should provide a minimum full engraving dose for these subjects, with a greater number expected for most patients. Should the minimum cell number, 1.6 x 10/9/, not be attained, the cryopreserved back-up cells will be reconstituted and administered to a subject on Day 0. It is anticipated that infusion of ex vivo-produced progenitors generated with the CPS will enhance engraftment and shorten time to recovery of granulocytes and platelets and, in so doing, reduce the incidence of infections, febrile episodes and the need for blood- and platelet transfusions. Amended August 5, 1996: In several in vitro studies using tumor cells that are easy to detect in small quantities (neuroblastoma and B-cell CLL), the expansion process appeared to passively purge tumor cells of slightly less than one log to greater than three logs. When combined with the smaller inoculum of marrow needed to initiate the bioreactors as compared to a normal marrow harvest, the depletions appear to be as high as four to five logs. It is anticipated that since the marrows must be histologically normal for patients to enter this trial, i.e., undetectable amount of breast cancer cells, that expansion of tumor cells will not be important clinically. This is especially true since there is additional in vitro data to show that the cytokines used do not stimulate the growth of tumor cells when used whether in vitro or in vivo when used in closely monitored clinical trials. The washing of the expanded cell products eliminates the amount of the cytokines to undetectable levels using a sensitive ELISA method. Only GMP (Good manufacturing process) cytokines are used for the expansion process, making it unlikely that any adverse clinical event will occur. Microbial contamination has not been a problem in the patients treated to date and in preliminary studies done preclinically. This is likely because of the closed system setup, growth and collection of the expanded cells, the use of antibiotics in the growth media, and the assays done 48 hours prior to the collection of the expanded cells (day 10). In addition, all patients will be on prophylactic antibiotics at the time of the cell infusions as per routine BMTU protocols. 2.3 High Dose Chemotherapy and Autologous Bone Marrow Transplant Breast Cancer Breast cancer is responsive to initial combination chemotherapy for metastatic disease with a 50-800,10 response rate and a 10-20% complete response rate, but few patients are cured and median duration of response is generally less than one year (20-24). Once patients relapse, the response to second-line therapy is 20-40% with very few complete responses (CR) and a median duration of response of 2-3 months and a median survival of 12 months. When patients with metastatic breast cancer receive high-dose chemotherapy, there is substantially higher complete response rate than that can be achieved with conventional treatment (25-38). Peters et al (39) used a regimen of Cyclophosphamide, Cisplatin, and BCNU or Melphalan in 22 ER-negative patients without prior induction chemotherapy, and reported a 54% CR rate and an overall response rate of 73% and a median duration of response of 7 months from the time of transplant. Antman et al recently reported similar results with a combination of high-dose Carboplatin. Cyclophosphamide and Thiotepa (26); each study reported approximately 20% 5-year disease-free survival. A recently published study that compared in a randomized fashion chemotherapy at conventional doses versus high dose therapy with stem cell rescue verified that this high dose approach is superior to conventional chemotherapy as measured both by progression-free as well as overall survival. Application of the same therapy to patients with Stage II breast cancer with greater than 10 positive nodes or Stage III disease has resulted in approximately 70% 5-year disease-free survival, substantially higher than that reported with standard adjuvant therapy in such patients. 3.0 BACKGROUND DRUG AND DEVICE INFORMATION 3.1 Description of the CPS The single-use, sealed, sterile cell culture device in the Aastrom CPS consists of three rigid plastic parts separated by a gas- permeable, water-impermeable membrane. The lower cell culture chamber is continuously perfused by growth medium. The cells expand in culture on the plastic surface of the cell culture bed. The upper cell culture chamber is provided with a constant flow of gas, such that oxygenation of the cell culture bed is accomplished by diffusion across the membrane and through the culture medium. Carbon dioxide is removed by the same mechanism. The medium used to perfuse the cultured cells is stored in a closed vessel in an adjacent refrigerator at 4 degrees C whose only external connection is by medical grade tubing. A "Y" connector, attached to the effluent line, allows sampling of the cell product prior to harvest, to test for bacterial and fungal contaminants. A detailed device description is provided in the Operators Manual provided by Aastrom. The system to be used will include dedicated Aastrom instruments, the Processor and incubators which replace standard laboratory equipment and perform all of the steps in the cell production automatically and more importantly sterily, and in a close system manner, after the initial inoculation of the cells into the CPS. The incubator contains a cold compartment for media storage for perfusion during the 12 day culture (perfusion begins on Day 3), and a 37 degrees C compartment in which the Cell Cassette is placed for the duration of the culture. 3.1.1 Cell Culture Conditions The hematopoietic cells are suspended in tissue culture medium composed of Iscove's Modified Dulbecco's Media supplemented with 10% fetal bovine serum, 10% horse serum, hydrocortisone (5x10/-6/ M), PIXY321 (5 ng/mi), glutamine (4 mM), Erythropoietin (Epo 0.1 U/ml), flt3L (5 ng/mi), gentamicin sulfate (5 Fg/ml), vancomycin (20 Fg/ml), sterile water for injection, and are inoculated into the CPS, starting after Day 3. The cells are cultured in the CPS for 12 days at 37 degrees C with the tissue culture medium continuously replaced with fresh medium. Sampling of the culture medium is carried out 48 hours prior to harvest, to allow testing for bacterial and fungal contaminants. The cell harvest is performed automatically, by a programmed schedule with the Processor. In this process, the non-adherent fraction is removed from the cell culture device by draining the growth medium from the cell culture device into the harvest bag. The chamber is then rinsed with 50 ml of Hank's Balanced Salt solution (HBSS). This is followed by agitation of the cell culture device and collection of the rinse into the harvest bag. The adherent layer is detached from the cell culture bed surface by injection of 50 ml of Trypsin-EDTA solution. This is also followed by agitation of the cell production device and collection of the rinse into the harvest bag. The chamber is then given a final rinse by injecting 50 ml of HBSS. This is followed by agitation of the cell production device and collection of the rinse into the harvest bag. Again this is done automatically, sterily in a closed system fashion. Following collection, the cells are washed free of culture medium as detailed in the Operator's Manual. The final product is suspended in appropriate media for immediate infusion. 3.1.2 Cell Culture Media Information Studies by Aastrom and the University of Michigan have shown that, after the cell washing regimen, the added growth factors and other reagents are below detectable limits, using a very sensitive ELISA assay (R&D Systems, Minneapolis, MN, and Immunex Research Corporation, Seattle, WA). These levels are well below the level of biological activity. The horse and fetal calf sera are tested preclinically for contamination for bacteria, fungi, mycoplasma, endotoxin, and viruses. The expanded cell product is washed (See Operators Manual) prior to transfusion. Nonetheless, the human toxicities and contraindications identified for these drugs are included below: 3.1.2.1 Recombinant Human Epo Recombinant Human Erythropoietin: Epoetin Alfa, Procrit, NOC 0062-7402-01 Amgen, Thousand Oaks, CA. Human Toxicity: Toxicities have included hypertension, headache, fever, seizures, and skin rash. The majority of these subjects had chronic renal failure, and these adverse events are frequent sequelae of chronic renal failure and were not necessarily attributable to Epo. Contraindications: Epo is contraindicated in subjects with: uncontrolled hypertension, known hypersensitivity to mammalian- derived products, and known sensitivity to human albumin. 3.1.2.2 PIXY321 PIXY321 is a fusion protein of granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin 3 (IL-3). 3.1.2.3 Recombinant GM-CSF Human Toxicity: Specific Toxicities include peripheral edema, pleural and/or pericardial effusions, fluid retention, sequestration of granulocytes in the lung, supraventricular arrhythmia, elevation of serum creatinine, and elevation of hepatic enzymes. Contraindications: GM-CSF is contraindicated in subjects with excessive leukemic blasts in the bone marrow or peripheral blood (greater than 10%), or with known hypersensitivity to GM-CSF, yeast-derived products, or any component of the product. 3.1.2.4 Flt3 Ligand (flt3L) The manufacturer of flt3L, Immunex Research and Development Corporation, Seattle, WA, has advised that a biologic Master File is in preparation for clinical, in vivo grade flt3L, and that the Master File will be submitted to the FDA in 1996, and will be available as reference for the purposes of this clinical feasibility trial (Letter, Immunex to Aastrom, December 11, 1995). Immunex has also advised that flt3L appeared to be well tolerated when administered to mice and monkeys for 14 days, at doses up to 400@g/kg/day. Based on the safety profile established by Immunex, including the animal data generated to-date, flt3L has no apparent toxicities, and does not stimulate the proliferation and detrimental activation of mast cells. As indicated above, the cells produced in the CPS are washed four times, resulting in a 5-log reduction in the presence of media components, to levels below detectable limits. An ELISA, supplied by Immunex, is used to determine residual flt3L levels subsequent to cell washing. 3.1.2.5 Horse Serum Contraindications: Known hypersensitivity to horse serum. 3.1.2.6 Fetal Calf Serum Contraindications: Known hypersensitivity to bovine serum. 3.2 CHEMOTHERAPY AGENTS AND CYTOKINES rhG-CSF (Filgrastim: NSC-614629) 3.2.1 Chemistry: rhG-CSF is a protein produced in E. Coli into which the gene synthesized for high expression in E Coli has been inserted. The 175 amino acid protein has a molecular weight of about 18,800 daltons. rhG-CSF differs from the natural protein (M.W. 19,600 daltons) in that the N-terminal amino acid is a methionine and is not 0-glycosylated. 3.2.2 Mechanism of Action: rhG-CSF is a hematopoietic regulator which has the ability to modulate the growth and maturation of myeloid cells, and in particular the proliferation and differentiation of granulocytes both in vitro and in vivo. 3.2.3 Human toxicity: Specific toxicities include medullary bone pain. musculoskeletal symptoms (muscle cramps, back and or leg pain); exacerbation of preexisting inflammatory conditions (psoriasis, arthritis, vasculitis); splenomegaly and hair thinning with prolonged administration. Elevated leukocyte alkaline phosphatase, uric acid, and lactate dehydrogenase. Progression of patients with myelodysplasia to acute myeloid leukemia occurred rarely during treatment with this agent. 3.2.4 Pharmaceutical Data: rhG-CSF is supplied in colorless, glass, single use vials containing 1.6 ml of buffered solation at a concentration of 0.3 mg/ml. It is formulated as a sterile, colorless liquid in a 10 mM sodium acetate buffer at pH 4.0. Administration: rhG-CSF will be administered in this study subcutaneously. It will be undiluted and be drawn into 3 cc syringes. To reduce the possibility of bacterial contamination in this product which contains no preservatives, the syringes should be stored at 2-8 degrees C and used within 24 hours of preparation, rhG-CSF should not be frozen and vials or syringes that have been frozen should not be used. 3.2.5 Supplier: This agent will be supplied through AMGEN for the trial free of charge to the patients. 3.3 Carboplatin (NSC-241240) (CBCDA) 3.3.1 Human Toxicity: Side effects of Carboplatin (CBDCA) include myelosuppression, nausea, vomiting, loss of appetite. Rare toxicities include gross hematuria, hyponatremia, ageusia, allergic reaction, peripheral neuropathy, veno-occlusive disease, loss of hair, liver damage, kidney damage, hearing loss, dizziness and blurred vision. Two cases of optic neuritis have been reported in patients receiving carboplatin which were thought to be possible drug-related events. A single case of severe pulmonary toxicity has been reported. 3.3.2 Pharmaceutical Data: Formulation: CBDCA is supplied as a sterile lyophilized powder available in single-dose vials containing 50 mg, 150 mg and 450 mg of Carboplatin for administration by intravenous injection. Each vial contains equal parts by weight of Carboplatin and mannitol. Immediately before use, the content of each vial must be reconstituted with either Sterile Water for Injection. USP, 5% Dextrose in Water, or 0.9% Sodium Chloride Injection, USP, according to the insert. Diluent Volume 50 mg 5 mL 150 mg 15 mL 450 mg 45 mL These dilutions all produce a Carboplatin concentration of 10 mg/ml. CBDCA can be further diluted to concentrations as low as 0.5 mg/ml with 5% Dextrose in Water or 0.9% Sodium Chloride Injection, USP (NS). 3.3.3 Storage & Stability: Unopened vials of CBDCA for injection are stable for the life indicated on the package when stored at controlled room temperature 150 - 300 C. and protected from light. When prepared as directed, CBDCA solutions are stable for 8 hours at room temperature. Since no anti-bacterial preservative is contained in the formulation, it is recommended that CBDCA solutions be discarded 8 hours after dilution. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. 3.3.4 Administration: Intravenous. 3.3.5 Supplier: CBDCA is commercially available and will be purchased through third party payers. 3.4 Cyclophosphamide (NSC-26271) 3.4.1 Mechanism of Action: Cyclophosphamide is a very weak alkylating agent, but enzymatic oxidation and a series of undefined subsequent reactions produce one or more molecules with alkylating activity. In experimental animals, the first step of activation occurs more extensively in the liver than in the neoplasm or other tissues of the host. 3.4.2 Toxicities: Human toxicity includes alopecia, nausea and vomiting, stomatitis, leukopenia, anemia, thrombocytopenia, sterility or decreased gonadal function, hemorrhagic cystitis and fibrosis of the bladder. 3.4.3 Pharmaceutical Data: Formulation: Cyclophosphamide is supplied in 100, 200, and 500 mg ampules containing white powder. The drug can be reconstituted in normal saline or 5% dextrose and water. 3.4.4 Stability: Store at room temperature. Do not store at temperatures above 90 degrees F. 3.4.5 Supplier: This drug is commercially available for purchase by the third party. 3.5 Thiotepa (Triethylene-thiophosphoramide) (NSC-6369) 3.5.1 Mechanism of Action: Thiotepa is a cytotoxic agent of the polyfunctional alkylating type related chemically and pharmacologically to nitrogen mustard. On the basis of tissue concentration studies, it is reported that Thiotepa has no differential affinity for neoplasms. Most of the drug appears to be excreted unchanged in the urine. 3.5.2 Human Toxicology: The major side effects of Thiotepa are pain at the site of injection, nausea and vomiting, anorexia, dizziness, headache, amenorrhea and interference with spermatogenesis. Febrile reaction and weeping from a subcutaneous lesion may occur as the result of a breakdown of tumor tissue. Allergic reactions are rare, but hives and skin rash have been noted occasionally. The serious complication of excessive Thiotepa therapy, or sensitivity to the effects of this agent, is bone marrow depression. If proper precautions are not observed, it may cause leukopenia, thrombocytopenia and anemia. The most reliable guide to Thiotepa toxicity is the white blood count. 3.5.3 Pharmaceutical Data: Formulation: Thiotepa is available in a powder form in 15 mg vials. The powder should be reconstituted in sterile water for injection. 3.5.4 Storage and Stability: Reconstituted solutions may be kept for five days in a refrigerator without a substantial loss of potency. Vials containing Thiotepa should be stored at 2-8 degrees C (35-46 degrees F). 3.5.5 Administration: The amount of diluent most often used is 1.5 ml resulting in a drug concentration of 5 mg in each 0.5 ml of solution. Thiotepa may be given by rapid intravenous administration or via continuous intravenous infusion. 3.5.6 Supplier: This drug is commercially available for purchase by the third party. 3.6 Intended Use The intended use of the CPS is to produce human stem- and hematopoietic progenitor cells to support subjects with compromised hematopoietic systems. A per-patient cell production procedure, beginning with 2.25 x 10/8/ nucleated bone marrow cells per device, will yield at least 1.6 x 10/9/ cells. The cells will not be infused if the cell yield is below this level; the back-up cells will be infused in such a case. 4.0 PATIENT ELIGIBILITY 4.1 Patients with histologically confirmed breast cancer with advanced disease as defined as high risk Stage II (greater than 10 LN), Stage III or stage IV (inflammatory, fixed to chest wall, or fixed axillary lymph nodes) or recurrent or metastatic disease. 4.2 Patients with measurable disease must have disease which is responsive to standard dose systemic chemotherapy administered prior to enrollment on study. Patients may have a maximum of two prior chemotherapy regimens for their disease. Patients with metastatic disease (beyond draining lymph nodes) with no evaluable or measurable disease following surgical resection, radiotherapy, or chemotherapy are still eligible. 4.3 Patients must have a Performance status of 0-1 by SWOG criteria (see appendix). As patient weight is used to calculate the minimum safe dose of CFU-GM to accomplish a transplant, and given the production capabilities of the CPS, patients in this initial trial must be less than 90 kg of actual body weight. 4.4 Patients must have received a cumulative adriamycin dose of less than 350 mg/m2 with no prior nitrosoureas, platinum or mitomycin C. 4.5 Patients must have recovered from prior therapy with at least 4 weeks since the last chemotherapy, 4 weeks since last radiotherapy, and 3 weeks since major surgery. 4.6 Patients must have adequate cardiac function as defined by a MUGA with an ejection fraction greater than or equal to 45%. Patients may not have active coronary disease as defined by angina or history of a myocardial infarction. In addition, patients must have no clinically apparent uncorrectable pulmonary disease such as corpulmonale or severe COPD, or be requiring oxygen therapy for any reason. 4.7 Patients with a history of or any evidence for brain metastases are ineligible. Head CT or MRI scans are not required if patients are asymptomatic. 4.8 Patients must have adequate organ function as defined by the following: Serum creatinine less than or equal to 1.5 mg/dl or calculated Cr-CI or greater than or equal to 60 ml/min: Hepatic function as defined by Bilirubin less than or equal to 2.0 mg/dl and AST/ALT less than or equal to 2 x institutional normal values: hematologic functional as defined by WBC greater than or equal to 3400/ul. Hgb greater than or equal to 9.0 gm/dl. platelet count greater than or equal to 140,000/ul. 4.9 Exclusion Criteria include: History of hypersensitivity to horse serum or fetal calf serum: Concurrent involvement in any other clinical trial that affects engraftment (e.g. other hematopoietic growth factors); treatment with any growth factors within two weeks; Previous pelvic radiotherapy rendering the marrow hypocellular, any co-morbid condition which, in the view of the Principal Investigator, renders the patient at high risk from treatment complications. 4.10 Patients must undergo a BM biopsy and BM must be either free of disease by standard histologic exam, and a cellularity on biopsy of at least 35%. 4.11 Patients must be less than 65 years of age. 4.12 Patients must be HIV negative. 4.13 Pregnant or lactating women may not participate. 4.14 Patients with prior hemorrhagic cystitis are ineligible. 4.15 Patients must be free of active systemic infection at the time of initiating therapy. Patients must have had no episodes of systemic mycotic infections, nor have required Amphotericin B therapy in the previous 12 months. 4.16 Patients must be free of active CNS diseases (seizures, etc.) 4.17 Patients must have signed an IRB approved consent form prior to trial enrollment. 4.18 Patients may not have an active second malignancy within the previous 2 years except localized non-melanoma skin cancer or uterine cervical cancer in situ. 5.0 TREATMENT PLAN 5.1 Registration All patients must be registered with the Data Management office at 708-327-3230 for entry on study. A total of 6-10 patients will be treated in this pilot study. 5.2 Bone Marrow Harvest Patients will undergo back-up bone marrow harvest at any time prior to initiation of the ablative chemotherapy, with cryopreservation, using standard techniques. Patients must have greater than 2 x 10/8/ nucleated cells per kg harvested, including greater than 0.5 x 10/6/ CD34- cells/kg. The bone marrow harvest will be performed by standard technique in an operating suite under general or epidural anesthesia. In a standard harvest, approximately 500-1500 ml of marrow is withdrawn. Patients will have the back-up bone marrow collected simultaneously with the cells for ex vivo production. If a sufficient number of cells are collected, the bone marrow collected will be processed and a small fraction utilized for the ex vivo culture described below, and the remainder of the cells will be cryopreserved per standard technique and held as a back-up for use if the prescribed number of cells is not produced or if graft failure occurs. The cells for the expansion will be collected from the posterior iliac crest or from the sternum at the initiation of the harvest procedure. No more than 5 cc of marrow for the expansion will be aspirated from each bone puncture. Approximately 40 ml of marrow will be aspirated in this fashion. 5.3 Ex Vivo Cell Production As mentioned in other parts of the Protocol, at the time of bone marrow harvest, all harvested marrow will be delivered to the bone marrow laboratory for processing. A portion of the harvested marrow will be used for cell production in the CPS and balance of the harvested marrow will be cryopreserved. Twelve days prior to the scheduled bone marrow transplant, 2.25 x 10/8/ mononuclear cells from freshly collected marrow will be placed into each CPS in the presence of PIXY321 (5 ng/mi), hydrocortisone (final concentration 5 x 10/-6/M), glutamine (4 mM), gentamicin sulfate (5 Fg/mi), vancomycin (20 Ff/mi), Epo (0.1 U/ml/day) and fit3L (5 ng/ml). The tissue culture medium will be supplemented with 1.0% fetal calf serum and 1.0% horse serum. All processing will be done using the dedicated CPS instrumentation. No standard laboratory equipment will be used for the expansion or processing of the cells. A sample of the harvested marrow will be sent for bacterial and fungal culture. The cell production will be performed in the Aastrom CPS, which is operated as a stand alone, dedicated piece of validated laboratory equipment (incubator, refrigerator, gas pumps) which provide for constant temperature (37C), pH (7.2-7.4), and delivery of sterile air (5% C02) to the hematopoietic cells. Two days prior to the completion of cell production, the cell culture effluent will be sampled to allow for bacterial and fungal testing including gram stain, endotoxin testing and mycoplasma. At the completion of the cell expansion process (12 days), the non-adherent fraction will be removed from the cell culture devices by draining the growth medium from the cell culture devices into the harvest bag. The devices will then be rinsed by using a syringe to inject 50 ml of an HBSS solution into an access port. This is followed by agitation of the cell culture device and collection of the rinse into the harvest bag. The adherent layer will be detached from the cell culture device surface by injection of 50 ml of Trypsin-EDTA solution via an access port. This is again followed by agitation of the cell culture device and collection of the rinse into the harvest bag. The chamber will be then given a final rinse with 50 ml of HBSS, again by injection via an access port. This is followed by agitation of the cell culture device and collection of the rinse into the harvest bag. The expanded cells will be washed according to the procedure outlined in the Operators Manual. All subjects will receive freshly harvested expanded cells. The expanded cells must be greater than 80% viable, as determined by Trypan blue dye, and the minimum total cell number, as determined by an automated cell counter, will be 1.6 x 10/9/ cells. As part of the standard laboratory in this Study, the total cell count, CFU-GM and LTC-IC will be determined for the starting and final cell number. The pre and post expansion sample will be sent for cytology and immunocytochemistry for breast cancer cells. Pre-transplant Evaluation of the cultured Cells: 48 hours prior to the collection of the expanded cells, the effluent from the CPS will be tested for bacterial and fungal contamination, as described above. If the bone marrow cultures are either visibly contaminated or are positively cultured for bacterial or fungal contamination, or if the cultures die, the expanded cells will not be returned to the subject, who will then simply receive her cryopreserved bone marrow. Flow Cytometry: Aliquots of the ex vivo produced cells (approximately 10 x 1 Or) will be removed at 12 days, placed in a tube containing sterile buffered medium, and shipped by overnight mail carrier to Aastrom Biosciences, Inc., Domino's Farms, 24 Frank Lloyd Wright Drive, Lobby L., Ann Arbor, MI, 48105. These cells will be analyzed for the presence of several cell surface markers (CD34, CD1 lb, CD15, CD33, CD3, CD4, CD8, CD19, CD71 and glycophorin A and other appropriate markers) in the laboratory at Aastrom as potential correlates for the cell production process. The Aastrom Laboratory operates under GLP (Good Laboratory Practices) guidelines. Release Criteria: Cells produced in the Aastrom CPS will be considered eligible for release and reinfusion if greater than 1.6 x 10' nucleated cells/kg are recovered after the expansion period and cell washing, and if greater than 80% of the nucleated cells are viable as judged by exclusion of Trypan blue dye. Microbial contamination studies collected from the expansion on Day 10 must be negative. If the expansion is not deemed sufficient, a patient will receive her backup marrow instead, without infusion of the expanded cells. 5.5 Transplant Regimen 5.4.1 High Dose Chemotherapy (STAMP V Regimen) Chemotherapy will begin a minimum of 48 hours following the last pheresis. Prior to the administration of chemotherapy, patients will receive anti-emetics including ondansetron and dexamethasone. Chemotherapy will consist of the following: Cylophosphamide 1500 mg/m2 Q day by continuous infusion (CI) for 4 days (d-7 through d-4) (96 hours) Total dose 6000 mg/m2 Thiotepa 125 mg/m2 Q day by CI for 4 days (d-7 through d-4) (96 hours) Total dose 500 mg/m2. Carboplatin 200 mg/m2 Q day CI for 4 days (d-7 through d-4) (96 hours) Total Dose 800 mg/m2. Supportive Issues: All patients will receive therapy through three separate lumens. The agents can not be mixed. Vigorous hydration will be included with a minimum of 200 cc/hour of IV fluids with diuretics as needed, while the chemotherapy is infusing and continuing till stem cell infusion. Patients will receive aggressive anti-emetic therapy with ondansetron, lorazepam, dexamethasone, etc. 5.4.2 Post-Transplant Growth Factor Support G-CSF (10 mcg/k/d) will be administered SQ until granulocytes greater than 2.0 x 1 O/9//l or greater than 1.0 x 1 O/9//l for 3 days. If granulocytes fall to less than 1.0 x 10/9//l, hematopoietic growth factor treatment can be resumed as indicated to maintain an absolute granulocyte count greater than 1.0 x 10/9//l. GM-CSF 250 mg/m2/d may be used in patients intolerant to G-CSF. Patients who require the administration of any myelosuppressive therapy in the first 7 days post transplant such as full dose Amphotericin B therapy will be required to receive the infusion of their back up marrow cells on that date. 5.4.3 Neutrophil Engraftment and Stopping Rules Neutrophil engraftment is defined as recovery as granulocytes to 0.5 x 10/9//l. Back-up autologous bone marrow will be infused intravenously per the following stopping rules: a. Back-up cells will always be administered to subjects on Day -21 if ANC is less than 0.5 x 10/9//l; if back-up cells are administered to a subject on Day-21, it is reasonable to assume that an ANC level of 0.5 x 10/9/ can only be reached between Day -21 and Day -25 if the cells produced in the CPS alone contribute to a subject's recovery, because the administration of back-up cells would not be expected to impact engraftment so rapidly, between Days -21 and-25. It is relevant to point out that ANC recovery in the Day -18-25 time frame is often experienced in standard bone marrow transplantation. b. If the ANC is greater than 500 on Day -28 but the platelet count is less than 20,000, the marrow cells will be infused on that date. c. If the patient is experiencing a severe infection or uncontrolled bleeding at any point during the period of pancytopenia, the back-up cells may be administered at the discretion of the investigator. 5.4.3.1 Stopping Rules With the above as background, stopping rules will be as follows: the trial will be stopped and reevaluated if two subjects fail to reach ANC 0.5 x 10/9/v/1 by Day +25, even with the administration of back-up cells on Day +21; The trial will also be stopped and reevaluated if four of the first five subjects, or if any five of the ten total subjects, required the administration of back-up cells because they failed to reach ANC 0.5 x 1 01/1 on or before Day +21. 6.0 PRETREATMENT EVALUATION 6.1 Complete history and physical examination, including SWOG performance status (Appendix C) 6.2 CBC, diff, and platelet count 6.3 SMA 12 and electrolytes 6.4 PT, PTT 6.5 Cardiac ejection fraction 6.6 Pulmonary function - DLCO 6.7 HIV, hepatitis, HTLV-1 (1764 panel) 6.8 Pregnancy test (in fertile women) 6.9 Tumor staging as indicated including bone scan with X ray of hot spots.

Early termination or D60 ------------------------ Laboratory profile Assessment of late toxicity Transfusion record Vital signs Concomitant medications Study completion questionnaire 8.3 Quality System Quality system procedures are designed to ensure that complete, timely, and accurate data are submitted, that protocol requirements are followed, and that complications and/or adverse reactions are immediately identified. The study monitors will promptly review all incoming data to identify inconsistent or missing data and adverse effects. Data problems will be addressed in telephone calls and correspondence to the investigational site and during site visits. Clinical monitoring procedures are described in Section 12 of this protocol. The Medical Monitor will receive immediate notification of adverse reactions Grade greater than 3. Both the site and -------------- Aastrom will maintain secure hard copy Case Record Forms and data files. 9.0 ADVERSE EFFECTS All adverse effects, whether or not considered anticipated, must be recorded on the data sheets. Unanticipated effects, as defined below, must be reported promptly to the sponsor for further evaluation and adequate required reporting to IRBs and investigators. 9.1 Anticipated Adverse Effects The preliminary clinical experience has not identified any serious adverse effects on health or safety caused by or associated with the CPS and no adverse effects related to the ex vivo use fit3 ligand are anticipated. Patients undergoing high dose chemotherapy are anticipated to experience anorexia, nausea, vomiting, mucositis, pancytopenia and associated infections while neutropenia. Some patients may develop organ toxicities from high dose therapy. The anticipated events are therefore those associated with bone marrow transplantation and/or chemotherapy. 9.2 Unanticipated Adverse Effects An unanticipated adverse effect is: Any serious effect on health or safety or any life-threatening problem, or death caused by, or associated with, a device, if that effect, problem, or death was not previously identified in nature, severity, or degree of incidence in the investigational plan, or any other unanticipated serious problem that relates to the rights, safety or welfare of subjects. [21 CFR 812.3 (s)]. In particular, any unexpected grade III or IV toxicities or any other serious event that might be attributable to the infusion of the expanded hematopoietic cells. Reporting requirements: Unanticipated adverse effects should be reported to the Aastrom Study Director, Thomas E. Muller, Ph.D., Vice President Regulatory Affairs, immediately by the Investigator and subsequently to BRI. Aastrom requires an immediate telephone report followed by a written report within 5 days. An investigator shall submit to Aastrom and the reviewing IRB a report of any unanticipated adverse device effect occurring as soon as possible, but no later than 10 working days after the investigator learns of the effect [21 CFR 812.150 (a) (1)]. Aastrom shall immediately conduct an evaluation and report the results of the evaluation to FDA and to reviewing IRB's and participating investigator(s) within 10 working days after the sponsor first receives the notice of the effect [21 CFR 812.150 (b) (1)]. If Aastrom determines that an unanticipated adverse effect presents an unreasonable risk to subjects, all investigations or parts of investigations presenting that risk shall be terminated as soon as possible [21 CFR 812.46 (b)]. 9.3 DEPARTURE FROM PROTOCOL When a situation occurs which requires a departure from the protocol, the Principal Investigator or other physician in attendance will contact the Medical Monitor by telephone: Thomas E. Muller, Ph.D. Vice President Regulatory Affairs Aastrom Biosciences, Inc. 24 Frank Lloyd Wright, Lobby L Ann Arbor, MI 48105 Telephone: 313-930-5555 Fax: 313-665-0485 Contact with the Medical Monitor will be made as soon as possible in order to discuss the situation and agree on an appropriate course of action. The patient's medical records and source documents will describe the departure from the protocol and the circumstance requiring it. 10.0 STATISTICAL CONSIDERATIONS AND DATA ANALYSIS 10.1 Evaluation of the Data All subjects will be evaluated. Descriptive statistics will be presented for demographic variables and baseline characteristics such as age, sex, medical history, physical examination results, cost information (especially as this relates to morbidity). The primary endpoint is the safety of the cells produced in the CPS. To assess the hematopoietic recovery post-infusion with ex vivo- produced cells, the day of engraftment is defined by the first day on which granulocytes less than 0.5 x 10/9//I are observed. Other secondary endpoints include nadir WBC and platelet count, febrile days, treatment related complications, antitumor response, and survival. Secondary Endpoints: a. The day of platelet transfusion independence with platelet count less than 20,000/MM3, 50,000/MM3 and 100,000/MM3 as defined by first of two consecutive time points on which platelet counts meet these endpoints not related to transfusion. b. Packed red blood cell transfusion and platelet transfusion requirements. c. Number of documented infections. d. Number of bleeding episodes. e. Number of days of hospitalization. Tumor response and response duration a. Patient survival at 90 days post transplant. 10.2 Safety variables Safety variables summarized will include incidence of adverse effects (including duration, severity, and outcome). Other safety variables reported will include the incidence and types of laboratory abnormalities. When the frequencies are sufficiently large, a Fishers exact test or Chi-square test may be used to compare enrolled subjects and historical controls including approximately 65 patients receiving autologous bone marrow transplants without expansion using the same preparative regimen. 10.3 Biological Effect Variables The following biological effects will be summarized: Incidence of febrile neutropenia Time to platelet transfusion independence Antibiotic usage: Number of days on antibiotics Number of total antibiotic days (# antibiotics x days) Number of days on antifungals Number of days on antivirals Number of documented infections Time to neutrophil engraftment Length of initial hospitalization 11.0 CLINICAL SUPPLIES A complete CPS description is provided in the Operators Manual. 1 11.1 Materials and Supplies 11.1.1 CPS Aastrom will supply the CPS, which includes the cell culture device.

Company contained in this Agreement and required to be performed on or prior to
the Closing shall have been performed in all material respects.

          4.  Representations and Warranties of the Purchaser. In order to
induce the Company to sell the Shares to the Purchaser, the Purchaser hereby
acknowledges, represents, warrants and agrees as follows:

              4.1.  None of the Shares of Series F Stock are (and the shares of
common stock, no par value ("Common Stock") issuable upon conversion thereof
("Conversion Shares") will not be) registered under the Securities Act of 1933
(as amended, the "Securities Act") or any state securities laws. The Purchaser
understands that the sale of the Shares is intended to be exempt from
registration under Section 4(2) of the Securities Act and/or the provisions of
Regulation D promulgated thereunder, based, in part, upon the representations,
warranties and agreements contained in this Agreement.

              4.2.  Neither the Securities and Exchange Commission nor any state
securities commission has approved any of the Shares or passed upon or endorsed
the merits of this transaction.

              4.3.  Prior to its execution of this Agreement, the Purchaser has
received from the Company (i) the draft Registration Statement on Form S-1 for
the Company dated August, 1996, together with a supplemental update thereto
dated October 3, 1996 (collectively called the "Disclosure Statement"), (ii) a
copy of the Amended Articles, for the purpose of creating the Series F Stock,
and (iii) the audited financial statements of the Company for the year ended
June 30, 1996, and the unaudited financial statements of the Company for the
month ended September 30, 1996 (the "Most Recent Financial Statements")
(collectively, the "Financial Statements").

                                       4

 
              4.4.  The Purchaser acknowledges that all documents, records and
books pertaining to the investment in the Shares, including the Disclosure
Statement, have been made available for inspection by the Purchaser, or by its
attorney, accountant, purchaser representative and/or tax advisor (collectively,
the "Advisors") and that the Purchaser and/or its Advisors have completed such
review as they deem to be necessary to make the decision to purchase the Shares.

              4.5.  The Purchaser has reviewed the merits and risks of an
investment in the Shares. The Purchaser and the Advisors have had a reasonable
opportunity to ask questions of and receive answers from members of management
of the Company concerning the offer and sale of the Shares and all such
questions have been answered to the full satisfaction of the Purchaser.

              4.6.  In evaluating the suitability of an investment in the
Shares, the Purchaser has not relied upon any representation or other
information (oral or written) other than as contained in documents or answers to
questions so furnished to the Purchaser or its Advisors by the Company.

              4.7.  No oral or written representations have been made or oral or
written information furnished to the Purchaser or its Advisors in connection
with this Agreement which were in any way inconsistent with the information
provided to the Purchaser or its Advisors, including the Disclosure Statement.

              4.8.  The Purchaser, together with the Advisors, have such
knowledge and experience in financial, tax and business matters so as to enable
each of them to utilize the information made available to each of them in
connection with the purchase of the Shares to evaluate the merits and risks of
an investment in the Shares and to make an informed investment decision with
respect thereto.

              4.9.  The Purchaser is not relying on the Company with respect to
the tax and other economic considerations of an investment in the Shares, and
the Purchaser has relied on the advice, or has consulted with, only its own
Advisors concerning tax matters.

              4.10. The Purchaser is acquiring the Shares solely for its own
account, for investment, and not with a view to or for subdivision, resale or
distribution, in whole or in part, and no other person has or will have a direct
or indirect beneficial interest in the Shares, other than for any partner or
shareholder owners of the Purchaser, if any.

                                       5

 
              4.11.  The Purchaser must bear the economic risk of the investment
indefinitely because none of the Shares of Series F Stock (or Conversion Shares)
may be sold, hypothecated or otherwise disposed of unless (i) subsequently
registered under the Securities Act and applicable state securities laws, or
(ii) an exemption from registration is available at that time. Legends shall be
placed on the Shares (and the Conversion Shares) to the effect that they have
not been registered under the Securities Act or applicable state securities laws
and appropriate notations thereon will be made in the Company's stock books.

              4.12.  The Purchaser has adequate means of providing for the
Purchaser's current financial needs and foreseeable contingencies and the
Purchaser accepts the fact that an investment in the Shares will not be liquid.

              4.13.  The Purchaser is aware that an investment in the Shares
involves a number of very significant risks and, in particular, acknowledges
that the Company is in the development stage. The Purchaser understands that the
risks associated with an investment in the Shares could result in, and the
Purchaser can sustain, a complete loss of its investment.

thereunder and, to the best of the Company's knowledge, without any default by
the Company of any material term thereunder; the Company has not been notified
of any default and has no reason to believe that it is in default of any term
thereunder. To the best of the Company's knowledge, no other party to any such
lease or agreement is in default of a material term thereunder. No event has
occurred and is continuing which, with due notice or lapse of time or both,
would constitute a default or event of default by the Company under any such
lease or agreement or, to the best of the Company's knowledge, by any other
party thereto. The Company's possession of such property has not been disturbed
and, to the best of the Company's knowledge, no claim has been asserted against
the Company adverse to its rights in such leasehold interests.

notice of default and are not in default (with due notice or lapse of time or
both) under any material lease, agreement or contract now in effect to which the
Company is a party or by which it or its property may be bound. The Company has
no present expectation or intention of not fully performing all its obligations
under each such material lease, contract or other agreement and the Company has
no knowledge of any breach or anticipated breach by the other party to any
contract or commitment to which the Company is a party.

              5.18.  Patents, Trademarks, Etc.

material applications for such which are in the process of being prepared, owned
by or registered in the name of the Company, or of which the Company is a
licensor or licensee or in which the Company has any right, and in each case a
brief description of the nature of such right. The Disclosure Statement contains
an accurate and complete description of all material licenses. The Company is in

or possesses adequate licenses or other rights to use all patents, patent
applications, trademarks, trademark applications, service marks, service mark
applications, trade names, copyrights, manufacturing processes, formulae, trade
secrets and know how (collectively, "Intellectual Property") necessary to the
conduct of its business as conducted, and no claim is pending or, to the best of
the Company's knowledge, threatened to the effect that the operations of the
Company infringe upon or conflict with the asserted rights of any other person
under any Intellectual Property, and, to the best knowledge of the Company,
there is no basis for any such claim (whether or not pending or threatened). No
claim is pending or threatened to the effect that any such Intellectual Property
owned or licensed by the Company, or which the Company otherwise has the right
to use, is invalid or unenforceable by the Company, or that the Company is not
in compliance with any term or condition of a license, and there is no basis for
any such claim (whether or not pending or threatened). The Company has not
granted or assigned to any other person or entity any right to manufacture, have
manufactured, assemble or sell the products or proposed products or to provide

                                      12

Disclosure Statement.

                     b.  The Company has taken reasonable security measures to
protect the secrecy, confidentiality, and value of the Company's trade secrets;
any of their employees and any other persons who, either alone or in concert
with others, developed, invented, discovered, derived, programmed, or designed
these secrets, or who have knowledge of or access to information relating to
them, have entered into agreements protecting the confidentiality thereof.
 
              5.19.  Proprietary Information of Third Parties. To the best of
the Company's knowledge, no third party has claimed or has reason to claim that
any person employed by or affiliated with the Company has (a) violated or may be
violating any of the terms or conditions of his employment, non-competition or
nondisclosure agreement with such third party, (b) disclosed or may be
disclosing or utilized or may be utilizing any trade secret or proprietary
information or documentation of such third party or (c) interfered or may be
interfering in the employment relationship between such third party and any of
its present or former employees. No third party has requested information from
the Company which suggests that such a claim might be contemplated. To the best
of the Company's knowledge, no person employed by or affiliated with the Company
has employed or proposes to employ any trade secret or any information or
documentation proprietary to any former employer, and to the best of the
Company's knowledge, no person employed by or affiliated with the Company has
violated any confidential relationship which such person may have had with any
third party, in connection with the development, manufacture or sale of any
product or proposed product or the development or sale of any service or
proposed service of the Company, and the Company has no reason to believe there
will be any such employment or violation. To the best of the Company's
knowledge, none of the execution or delivery of this Agreement, or the carrying
on of the business of the Company as officers, employees or agents by any
officer, director or key employee of the Company, or the conduct or proposed
conduct of the business of the Company, will conflict with or result in a breach
of the terms, conditions or provisions of or constitute a default under any
contract, covenant or instrument under which any such person is obligated.

              5.20.  Compliance With Law. To the best of the Company's
knowledge, the Company has complied with all laws, rules, regulations and orders
applicable to its business, operations, properties, assets, products and
services, the violation of which would have a material adverse effect upon the
Company, and the Company has all necessary permits, licenses and other
authorizations required to conduct its business as it is now conducted. To the
best of the Company's knowledge, there is no existing law, rule, regulation or
order, and the
                                       13

 
Company after due inquiry is not aware of any proposed law, rule, regulation or
order, whether Federal or state, which would prohibit or restrict the Company
from, or otherwise materially adversely affect the Company in, conducting its
business, in which it is now conducting business or in which it proposes to
conduct business, other than the customary governmental approvals required for
medical products. Without limiting the foregoing in any manner, to the best of
the Company's knowledge, the Company has complied in all material respects with
all applicable laws relating to the employment of labor, including provisions
relating to wages, hours, equal opportunity, collective bargaining and the
payment of Social Security and other taxes, with the Employee Retirement Income
Security Act of 1974, as amended, with the Occupational Health and Safety Act,
and with the Americans With Disabilities Act. To the best of the Company's
knowledge, the Company is in full compliance with the Immigration Reform and
Control Act of 1986, as amended, and all key employees who are not United States
citizens are currently authorized under United States immigration laws to hold
United States employment and will continue to have such employment authorization
throughout the term of the Series F Stock investment, and are otherwise in
compliance with United States immigration laws.

              5.21.  Loans and Advances. The Company does not have any
outstanding loans or advances to any person and is not obligated to make any
such loans or advances, except as reflected on the Financial Statements, and
except, in each case, for advances to employees of the Company in respect of
reimbursable business expenses anticipated to be incurred by them in connection
with their performance of services for the Company. In the near future, the
Company expects to borrow funds from the State Treasurer of the State of
Michigan pursuant to a pending convertible loan commitment, as described in
Section 12 hereof.

              5.22.  Assumptions, Guaranties, Etc. of Indebtedness of Other
Persons. Except as disclosed in the Financial Statements, the Company has not
assumed, guaranteed, endorsed or otherwise become directly or contingently
liable on any indebtedness of any other person (including, without limitation,
liability by way of agreement, contingent or otherwise, to purchase, to provide
funds for payment, to supply funds to or otherwise invest in the debtor, or
otherwise to assure the creditor against loss), except for guaranties by
endorsement of negotiable instruments for deposit or collection in the ordinary
course of business.

              5.23.  Governmental Approvals. Subject to the accuracy of the

the transactions contemplated hereby contains an untrue statement of a material
fact or omits a material fact necessary to make the statements contained therein
not misleading. As of the date hereof, no facts have come to the attention of
the Company which would, in its opinion, require the Company to revise or
amplify the Disclosure Statement.

              5.25.  Offering of Shares. This Agreement is being made by the
Company pursuant to an exemption from the registration requirements of the
Securities Act.

                                  Litigation


     1.   R. M. Schwartz.  The Company has written letters to a former employee,
Richard M. Schwartz, Ph.D. and Dr. Schwartz's new employer, SyStemix, (i)
reminding them of Dr. Schwartz's duty to maintain strict confidentiality as to
the Company's trade secrets; and (ii) asking if there has been any breach of
this confidentiality obligation; and (iii) commenting that a new invention by
Systemix's appears to be derived from the Company's trade secrets.  Systemix and
Dr. Schwartz have denied any use of the Company's trade secrets.  The Company
has reserved its rights in this matter, but does not presently contemplate
pursuing this potential claim in the near future.

     2.   Sundberg-Ferar.  The Company has commenced an arbitration proceeding
against Sundberg-Ferar ("S-F") for what the Company asserts to be a breach by S-
F of the contractual obligations of S-F to not solicit away from the Company's
employment its employees.  This arbitration is for the Company to seek damages
recovery from S-F, although if the Company is not successful in this
arbitration, then S-F may seek to recover its attorney's fees incurred in
defending the arbitration proceedings.

          "IPO" shall mean an initial public offering of stock by the Company

                                       1


 
      2.  Loan Commitment.
          --------------- 

          2.1.  In accordance with and subject to the terms of this Agreement,
the State agrees to make Loans to the Company, in accordance with Funding
Requests, up to an aggregate principal balance owing on the Loans not to exceed
$5 million.

          2.2.  Each Loan shall be for an amount not less than $1 million
principal.

          2.3.  Each Funding Request shall be in writing and shall be submitted
by the Company to the State requesting a Loan to be made from the State to the
Company in 45 days from the date of the Funding Request (or such longer period
as may be specified by the Company).  The Company may not submit a Funding
Request prior to October 15, 1996, nor after September 1, 1997.  The Company may
not submit more than three (3) Funding Requests.

          2.4.  As a precondition to the Company's first Funding Request, the
Company must first have requested and obtained (or be in the process of
obtaining) all of the $5 million equity investment from Cobe Laboratories, Inc.
("Cobe") for purchasing Series F preferred stock.

          2.5.  Each Loan shall be evidenced by a promissory note signed and
delivered by the Company to the State, specifying the principal amount of the
Loan as specified in the Funding Request, in the form of the promissory note
attached hereto as Exhibit A.  As specified in more detail in said promissory
note, (a) simple interest shall accrue at 10% per annum and be payable with
principal at maturity, (b) the Company shall have an option to prepay any or all
of the principal and/or accrued interest at any time, without penalty, (c) in
lieu of the Company repaying the promissory note in cash, the Company shall have
the option to satisfy the promissory note by converting any unpaid principal and
accrued interest owing on the promissory note into equity stock of the Company,
in accordance with the provisions set forth in the promissory note, (d) if the
Company does not elect to convert the promissory note into equity, then all
principal and accrued interest owing on the promissory note shall mature and be
fully due and payable on the Maturity Date, which shall be the earlier of (i) 60
days following consummation of the Company's IPO or Qualifying Financing or (ii)
12 months following the date when the State makes the first Loan to the Company,
and all promissory notes shall have this same Maturity Date, (e) the Company's
obligations on the promissory notes shall be senior to or in parity with all
other unsecured debt owed by the Company, and (f) within 15 days following
completion of an IPO or Qualifying Financing, the Company shall give written
notice to the State specifying whether the Company will (i) repay the promissory
note at the Maturity Date, or (ii) convert the promissory note into equity stock
of the Company.

                                       2

 
          2.6.  The parties acknowledge that the Company is obligated, pursuant
to previously existing agreements, to offer to many of the Company's existing
shareholders the right to participate and invest in the same convertible debt
commitment as is set forth in this Agreement.  In the event any of the Company's
other shareholders elect to so participate, then the $5 million level of the
State's commitment shall be reduced on a dollar for dollar basis by each dollar
committed by another shareholder for this convertible debt investment.  The
number of Commitment Stock Warrants (hereinafter described) grant to the State
shall also be reduced on a prorata basis to the extent the Company's other
shareholders elect to so participate.  For example, if the other shareholders
commit in the aggregate to $1 million convertible debt on the same terms as set
forth in this Agreement, then the State's commitment level pursuant to this
Agreement shall be reduced from $5 million to $4 million, and the Commitment
Stock Warrant shall be reduced from 104,167 warrant shares to 83,334 warrant
shares (i.e., a one-fifth reduction).

          2.7.  Once the Company has submitted a Funding Request to the State in
accordance with the foregoing, and met the conditions as specified in Section 3
hereof, the State shall make the requested loan to the Company by wiring funds
to the Company's bank account, pursuant to wire transfer instructions furnished
to the State by the Company.

          2.8.  Upon the Company completing an IPO, the State's obligation to
make further loan advances will terminate.

      3.  Conditions for Each Loan.  As a condition to the State's
          ------------------------                                
obligation to make each Loan in accordance with the Company's Funding Request,
the Company shall submit to the State the following:

          a.  the promissory note for said Loan, duly signed by the Company,
with authority for the State to insert the date on said promissory note when the
State advances the Loan proceeds to the Company;

          b.  a certificate signed by the President and the Chief Financial
Officer of the Company certifying that, (i) the Company is not in material
default under any of the Company's material obligations, and (ii) to the best of
their knowledge and belief, all items of the information furnished to the State
(via Joseph Taylor or such other representative as may be designed by the
State), including without limitation,  financial statements, minutes of Board
meetings, draft Registration Statement on Form S-1 for the Company, dated August
1996, as supplemented by an update dated as of October 3, 1996 (collectively
called the "Disclosure Statement"), and all other written materials and oral
information, remain true and correct, and, when read together, do not contain
any untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements contained therein not misleading, and
(iii) the Company's

                                       3

 
Board of Directors has authorized the officers of the Company to execute and
deliver the promissory note, and (iv) the Company has previously requested and
obtained (or is in the process of obtaining) $5 million of equity funding from
Cobe pursuant to that certain Stock Purchase Commitment Agreement between Cobe
and the Company.

          4.  Equity Conversion.  In lieu of the Company repaying the promissory
              -----------------                                                 
notes in cash, the Company shall have the option to convert any unpaid principal
and interest owing on the promissory notes into equity stock of the Company, in
accordance with the following provisions:

              a.  if, by the Maturity Date, the Company has an IPO or another
Qualifying Financing, then the Company has the option to convert the principal
and interest owing on the promissory notes into the Company's capital stock,
consisting of common stock issued pursuant to the IPO or the preferred stock or
other equity issued by the Company pursuant to the Qualifying Financing, at a
conversion price equal to 90% of the price paid by the other investors in the
IPO or Qualifying Financing (without deduction for underwriter's commissions and
discounts).

              b.  if, by the Maturity Date, the Company has not yet had an IPO
or another Qualifying Financing, and if the Company does not repay the
promissory notes in cash by the Maturity Date, then the principal and accrued
interest owing on the promissory notes shall be converted into a new series of
the Company's preferred stock (to be designated as Series G preferred stock), at
$4.65 per share, which preferred stock shall have a liquidation preference and
conversion price of $4.65 per share, with a liquidation preference senior to all
other preferred stock existing at the time of issuance of the Series G preferred
stock, and with other rights, preferences and privileges comparable to the
Company's Series E preferred stock. Said Series G preferred stock will include a
customary weighted average anti-dilution protection provision applicable to the
Company's next following sale of preferred stock of at least $1 million to new
investors.

              c.  In the event the "Qualifying Financing" is an "Operational
Plan" as described in subparagraph (iii) of the definition of a Qualifying
Financing, , then the equity securities into which the principal and interest
owing on the promissory notes shall be converted pursuant to Section 4 hereof
shall be a new series of the Company's preferred stock (Series G) having rights,
preferences and privileges comparable to those of the Company's Series E
preferred stock, but with a conversion price and liquidation preference being
equal to 90% of the then current fair market value of the Company's then most
recently issued preferred stock sold to cash investors (excluding stock sold to
RPR), and with a liquidation preference senior to all other preferred stock
existing at the time of issuance of the Series G preferred stock. Said fair
market value of said preferred stock shall be determined by mutual agreement
between the Company and the State, but if no

                                       4

 
mutual agreement can be reached, then said fair market value shall be determined
by a nationally recognized investment banking firm which is mutually selected by
the Company and the State, with the fees for obtaining said valuation
determination to be borne equally by the Company and the State.  Said Series G
preferred stock will include a customary weighted average anti-dilution
protection provision applicable to the Company's next following sale of
preferred stock of at least $1 million to new investors.

      5.  Stock Warrants.
          -------------- 

          5.1.  As consideration for the State entering into this Agreement for
a $5 million commitment, the Company shall issue to the State a stock warrant
(the "Commitment Stock Warrant") entitling the State to purchase up to 104,167
shares of the Company's common stock (subject to reduction as specified in
Section 2.6 hereof), on the following terms:

                i.  the exercise price shall be the lesser of:

                    (a) $6.00 share, increasing by $2.00 per share on each
anniversary of the date the Company completes its IPO; or

                    (b) 85% of the fair market value of the Company's stock at
the time the stock warrant is exercised, which value shall be determined as
follows:

                        (1) if the Company's common stock is traded in the
public stock market at the time the stock warrant is exercised, then said fair
market value shall be the public trading price, calculated using the average of
the last trading price of the day for the 20 trading days preceding the date of
exercise.

                        (2) if the exercise of the stock warrant is made prior
to the Company completing an IPO, then said fair market value shall be the fair
market value of the Company's then most recently issued preferred stock sold to
cash investors (excluding stock sold to RPR), determined by mutual agreement
between the Company and the State. If no such mutual agreement is reached, then
the fair market value of said preferred stock shall be determined by a
nationally recognized investment banking firm which is mutually selected by the
Company and the State, with the fees for such determination to be borne equally
between the Company and the State.

                ii.  The warrant shall become exercisable any time after the 
earlier of (a) 90 days after the Company completes its IPO or a Qualifying
Financing, or (b) October 15, 1999 (provided that this date is not within 90
days

                                       5

 
after the IPO is completed, in which event the warrant shall be exercisable at
the end of said 90 days).

                iii.  The warrant shall expire on October 15, 2000, to the 
extent it has not been exercised prior thereto.

          5.2.  In addition to the Commitment Stock Warrant, the Company shall
also issue to the State a "Funding Stock Warrant" applicable to each increment
of Loan funding advanced by the State to the Company pursuant to Section 2
above, based upon a 7.5% coverage formula, namely:  12,500 warrant shares for
each $1 million of principal Loan funds advanced, or an aggregate of 62,500
warrant shares if all $5 million of Loan funds are advanced.  The terms of said
Funding Stock Warrants shall be the same as the terms of the above-described
Commitment Stock Warrant.

          5.3.  The form of the Commitment Stock Warrant and the Funding Stock
Warrant shall be as set forth on Exhibit B attached hereto.

      6.  Piggyback Stock Registration Rights.  The shares to be issued by
          -----------------------------------                             
the Company to the State pursuant to the conversion of the Loan into equity
(Section 4 above), and upon exercise of the stock warrants (Section 5 above),
shall have piggyback stock registration rights comparable to those given by the
Company to the holders of the Company's Series E preferred stock.

      7.  General Provisions.
          ------------------ 

          7.1.  Irrevocability; Binding Effect.  The State hereby acknowledges
                ------------------------------                                
and agrees that the commitment hereunder is irrevocable by the State, except as
required by applicable law, and that this Agreement shall be binding upon and
inure to the benefit of the parties and their respective successors, legal
representatives, and permitted assigns.

          7.2.  Modification.  This Agreement shall not be modified or waived
                ------------                                                 
except by an instrument in writing signed by the party against whom any such
modification or waiver is sought.

          7.3.  Notices.  A notice or other communication required or permitted
                -------                                                        
to be given hereunder shall be in writing and shall be given by any means,
including without limitation, mail, express delivery service, or facsimile.  Any
notice or other communication shall be deemed given at the time it is received
at the party's address set forth on the signature page of this Agreement, or at
such other address as the party shall have furnished in writing in accordance
with the provisions of this Section 7.3.

                                       6

 
          7.4.  Assignability.  This Agreement and the rights, interests and
                -------------

8 EXHIBIT A Promissory Note 9 PROMISSORY NOTE $_______________ Ann Arbor, Michigan ____________, 199_ 1. Obligation.

Maker's obligations on this Promissory Note shall be senior to or in parity with all other unsecured debt owed by Maker. 2. Series of Promissory Notes. This Promissory Note is one of a series -------------------------- of promissory notes of Maker being issued to Lender in pursuant to the Convertible Loan Commitment Agreement dated ___________, 1996, by and between Lender and Maker (the "Loan Agreement"). Capitalized terms not otherwise defined in this Promissory Note shall have the meanings given to such terms in the Loan Agreement. 3. Interest. The outstanding principal balance shall bear interest from -------- the date of disbursement to Maker at the rate of ten (10%) per annum, simple interest, until repaid in full. Accrued interest under this Promissory Note shall be payable at the Maturity Date, as specified herein. If interest is not be paid when due, it shall thereafter bear interest at the same rate as principal bears interest. 4. Maturity Date. The entire unpaid principal balance and all unpaid ------------- accrued interest shall be due and payable on the "Maturity Date", which shall be the earlier to occur of (i) sixty (60) days following consummation of Maker's IPO or Qualifying Financing; or (ii) ________________, 199__. 5. Prepayment. Maker shall have the option to prepay any or all of the ---------- principal and/or accrued interest owing on this Promissory Note at any time, without penalty or premium. 6. Conversion to Equity. -------------------- a. Within 15 days following completion of an IPO or a Qualifying Financing, Maker shall give written notice to Lender specifying whether Maker will (1) repay this Promissory Note at the Maturity Date, or (2) convert this Promissory Note into equity stock pursuant to Section 6b hereof. 10 b. In lieu of Maker repaying this Promissory Note in cash, Maker shall have the option to convert any unpaid principal and interest owing on this Promissory Note into equity stock of Maker, in accordance with the following provisions: (i) if, by the Maturity Date, Maker has an IPO or a Qualifying Financing (as defined below), then Maker has the option to convert the principal and interest owing on this Promissory Note into Maker's capital stock, consisting of common stock issued pursuant to the IPO or the preferred stock or other equity issued by Maker pursuant to the Qualifying Financing, at a conversion price equal to 90% of the price paid by the other investors in the IPO or Qualifying Financing (without deduction for underwriter's commissions and discounts). (ii) if, by the Maturity Date, Maker has not yet had an IPO or a Qualifying Financing, and if Maker does not repay this Promissory Note in cash by the Maturity Date, then the principal and accrued interest owing on this Promissory Note shall be converted into a new series of Maker's preferred stock (to be designated as Series G preferred stock), at $4.65 per share, which preferred stock shall have a liquidation preference and conversion price of $4.65 per share, with a liquidation preference senior to all other preferred stock of Maker, and with other rights, preferences and privileges comparable to Maker's Series E preferred stock. Said Series G preferred stock will include a customary weighted average anti-dilution protection provision applicable to Maker's next following sale of preferred stock of at least $1 million to new investors. c. As used in this Promissory Note, the term "Qualifying Financing" means any one of the following: (i) Maker entering into (or completing) a term sheet agreement (or other agreement) with investors or an underwriter by the Maturity Date, which provides for: (1) a scheduled closing by February 1, 1998, (2) a public or private sale of equity securities of Maker, the gross proceeds from which equity sale is to aggregate to at least $10 million, (3) the proceeds of the sale are not designated by the investor for specified limited purposes, (4) the price per share for the sale is set by mutual agreement between Maker and new investors who invest at least $1 million, and (5) the sale of equity securities actually is consummated by February 1, 1998; or (ii) Maker entering into (or completing) a term sheet agreement (or other agreement) by the Maturity Date for the merger or sale of Maker at a value of at least $85 million, with (a) a scheduled closing for the merger or sale to be by February 1, 1998, and (b) the merger or sale actually is consummated by February 1, 1998; or (iii) Maker's Board of Directors adopting an Operational Plan for Maker to continue its operations in the ordinary course of business through December 31, 1998, funded by Maker's own cash flow and other resources, without requiring outside equity or debt investment in Maker. In the event the "Qualifying Financing" is such "Operational Plan", then the equity securities into which the principal and interest owing on this Promissory Note shall be converted pursuant to Section 6bi above shall be a new series of Maker's preferred stock 11 (Series G) having rights, preferences and privileges comparable to those of Maker's Series E preferred stock, but with a conversion price and liquidation preference being equal to 90% of the then current fair market value of Maker's then most recently issued preferred stock sold to cash investors (excluding stock sold to RPR), and with a liquidation preference senior to all other preferred stock. Said fair market value of said preferred stock shall be determined by mutual agreement between Maker and Lender, but if no mutual agreement is reached, then said fair market value shall be determined by a nationally recognized investment banking firm which is mutually selected by Maker and Lender, with the fees for obtaining said valuation determination to be borne equally by Maker and Lender. Said Series G preferred stock will include a customary weighted average anti-dilution protection provision applicable to Maker's next following sale of preferred stock of at least $1 million to new investors. 7. Default. Upon a default by Maker, as specified below, Lender may ------- declare the entire unpaid balance of principal and accrued interest immediately due and owing. Each of the following events shall constitute a default: a. Default in the payment of principal or interest due hereunder, and such default continues for a period of thirty (30) days after the due date thereof. b. The making of an assignment for the benefit of creditors by Maker, or the appointment of a receiver for all or substantially all of Maker's property, or the filing by Maker of a petition in bankruptcy or other similar proceeding under law for the relief of debtors; or c. The filing against Maker of a petition in bankruptcy or other similar proceeding under law for relief of debtors, and such petition is not vacated or discharged within sixty (60) days after the filing thereof 8. Costs of Collection. If this Promissory Note is not paid when due, ------------------- whether at maturity or by acceleration, Maker promises to pay all costs incurred by Lender in collecting the amounts due hereunder, including reasonable attorneys' fees and expenses incurred by Lender in connection with any insolvency, bankruptcy, reorganization, arrangement or other similar proceedings involving Maker which in any way affects the exercise by Lender of its rights and remedies under this Promissory Note. 9. Waiver. Presentment, demand, protest, notices of protest, dishonor ------ and non-payment of this Promissory Note and all notices of every kind are hereby waived. No single or partial exercise of, or forbearance from exercising, any power hereunder or under any other agreement or instrument pertaining to this Promissory Note shall preclude other or further exercises thereof or the exercise of any other power. No delay or omission on the part of Lender in exercising any right hereunder shall operate as a waiver of such right or of any other right under this Promissory Note. 10. Governing Law. Principal and interest are payable in lawful money of ------------- the United States. This Promissory Note has been executed and delivered by Maker in the State of Michigan and shall be governed by and construed in accordance with the laws of the State of 12 Michigan. In any action brought under or arising out of this Promissory Note, Maker hereby consents to the jurisdiction of any competent court within the State of Michigan and consents to service of process by any means authorized by Michigan law. 11.

Upon payment of the Exercise Price as provided in this Section 4, the Holder shall thereupon be entitled to receive the number of Shares of Warrant Stock determined as provided hereunder. If this Warrant should be exercised in part only, the Company shall, upon surrender of this Warrant for cancellation, execute and deliver a new Warrant evidencing the right of the Holder to purchase the balance of the Shares purchasable hereunder. Upon receipt by the Company of this Warrant in proper form for exercise and accompanied by payment, the Holder shall be deemed to be the holder of record of the Shares of Warrant Stock issuable upon such exercise, notwithstanding that the stock transfer books of the Company shall then be closed or that certificates representing such shares of Warrant Stock shall not then be actually delivered to the Holder. 5. Expiration Date. This Warrant shall expire October 15, 2000, or --------------- such earlier date as the Company may complete a merger or sale of the Company, so long as the Holder is given at least 60 days' prior written notice of the proposed merger or sale, and an opportunity to exercise this Warrant, as contemplated by Section 12 hereof. 6. Reservation of Shares. The Company hereby agrees that it will at --------------------- all times reserve and keep available for issuance and delivery upon exercise of this Warrant such number of shares of Stock as shall be issuable from time to time upon exercise of this Warrant. 7. Fractional Shares. No fractional Shares or scrip representing ----------------- fractional Shares shall be issued upon the exercise of this Warrant. With respect to any fraction of a Share called for upon any exercise hereof, the Company will pay to the Holder cash in an amount equal to such fraction multiplied by the then current market value of such fractional Share, determined in such reasonable manner as may be determined by the Board of Directors of the Company, such determination to be final and binding on the Holder. 8. Exchange, Assignment or Loss of Warrant. This Warrant is --------------------------------------- exchangeable, without expense, at the option of the Holder, upon presentation and surrender to the Company or at the office of its stock transfer agent, if any, for other Warrants of different denominations entitling the Holder to purchase in the aggregate the same number of Shares of Warrant Stock purchasable hereunder. This Warrant may be divided or combined with other Warrants which carry the same rights upon presentation hereof at the office of the Company or at the office of its stock transfer agent, if any, together with a written notice signed by the Holder specifying the denominations in which new Warrants are to be issued. The term "Warrant" as used herein includes any Warrants issued in substitution for or replacement of this Warrant, or into which this Warrant may be divided or exchanged. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, or (in the case of mutilation) upon surrender and cancellation of this Warrant, as the case may be, the Company shall issue to the Holder a new Warrant of like tenor and date. 9. Rights of Holder. The Holder shall not, by virtue hereof, be ---------------- entitled to any rights of a shareholder of the Company, either at law or equity, and the rights of the Holder are 17 limited to those expressed in this Warrant and are not enforceable against the Company except to the extent set forth herein. 10. Adjustment Provisions. --------------------- 10.1 Adjustment of Exercise Price for Stock Splits, Stock ---------------------------------------------------- Dividends Etc. In case the Company shall at any time or from time to time - ------------- issue stock by way of dividend or other distribution on any capital stock of the Company, or subdivide or combine the outstanding shares of Stock, the Exercise Price shall be proportionately decreased in the case of such issuance (on the day following the date fixed for determining shareholders entitled to receive such dividend or other distribution) or decreased in the case of such subdivision or increased in the case of such combination (in either case, on the date that such subdivision or combination shall become effective). 10.2 No Adjustment for Small Amounts. Anything in this Section ------------------------------- 10 to the contrary notwithstanding, the Company shall not be required to give effect to any adjustment in the Exercise Price unless and until the net effect of one or more adjustments pursuant to this Section 10 shall cause a change of the Exercise Price by at least one cent, but when the cumulative net effect of more than one adjustment so determined shall be to change the Exercise Price by at least one cent, such change in the Exercise Price shall then be given effect. 10.3 Number of Shares Adjusted. Upon any adjustment of the ------------------------- Exercise Price pursuant to this Section 10, the Holder shall thereafter (until another such adjustment) be entitled to purchase, at the adjusted Exercise Price, the number of Shares of Warrant Stock, calculated to the nearest full share, obtained by multiplying the number of Shares of Warrant Stock issuable upon exercise of this Warrant prior to such adjustment by the Exercise Price in effect prior to such adjustment and dividing the product so obtained by the new Exercise Price. 11. Officer's Certificate. Whenever the Exercise Price shall be --------------------- adjusted pursuant to Section 10, the Company shall promptly create and file in the custody of its Secretary or an Assistant Secretary at its principal office, and with its stock transfer agent, if any, and mail to the Holder at his or her address as listed on the books and records of the Company, an officer's certificate showing the adjusted Exercise Price determined as herein provided and setting forth in reasonable detail the facts requiring such adjustment. The original of each such officer's certificate shall be available for inspection during office hours at the Company's principal place of business. Such certificate shall be conclusive as to the correctness of such adjustment. 12. Reclassification, Reorganization or Merger. In case of any ------------------------------------------ reclassification, capital reorganization or other change of outstanding shares of Stock of the Company (other than a change in par value, or as a result of an issuance of Stock by way of dividend or other distribution or of a subdivision or combination), or in case of any sale or conveyance to another corporation of the property of the Company as an entirety or substantially as an entirety, the Company shall cause effective provision to be made so that the Holder shall have the right thereafter, by exercising this Warrant, to purchase the kind and amount of shares of stock and other securities and property receivable upon such reclassification, capital reorganization or other change, consolidation, sale or conveyance as the Holder would have received had this 18 Warrant been exercised immediately prior to such event. Any such provision shall include provision for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Warrant. The foregoing provisions of this Section 12 shall similarly apply to successive reclassifications, capital reorganizations and changes of shares of Stock. In the event of a merger (where the Company is not the surviving entity), consolidation or other sale or conveyance (in all such cases where the consideration to be received by the holders of the Stock of the Company consists solely of cash or securities registered under the Securities Act of 1933, as amended, the "Act") and if requested by the Company, the Holder shall agree to exercise this Warrant immediately prior to such event, or otherwise the expiration date shall be accelerated to the day preceding the effective date of the merger, consolidation or other sale or conveyance. 13. Stock Registration. Upon exercise of this Warrant, and with ------------------ respect to the Warrant Stock acquired by said exercise, the Holder shall become a "Purchaser" under, and be entitled to all of the rights set forth in, the Stock Registration Rights Agreement, dated as of April 2, 1992, as amended (the "Registration Agreement"), a copy of which has been given previously to the Holder, and the Holder agrees to be bound by the terms and conditions of the Registration Agreement, as applicable. Except as set forth in the Registration Agreement, the Company has no obligation to register any of the Shares of Warrant Stock issuable upon the exercise of this Warrant. Unless and until the shares of Warrant Stock are registered under the Act, the resale of the Warrant Stock by the Holder is restricted, and the Shares will be subject to the limitations and restrictions of Rule 144 after the Company has a public stock offering, and the Shares may be sold by the Holder only pursuant to exemptions from the registration requirements of the Act, if any are then available. In connection with an underwritten initial public offering by the Company of its equity securities pursuant to a registration statement filed under the Act, the Holder shall not sell, pledge, dispose or transfer any interest in (or otherwise agree to engage in any of the foregoing transactions with respect to) any of the Warrant Stock or any interest herein without the prior written consent of the Company or its underwriters for a period of up to 180 days following the effectiveness of the registration statement, and the Holder agrees to enter into a "lockup letter" so restricting such transfers; provided, that the Holder's obligations to refrain from transferring Warrant Stock and to enter into a lockup letter shall be effective only if the executive officers and directors of the Company also enter into similar lockup letters. In order to enforce the limitations of this Section 13, the Company may impose stop-transfer instructions with respect to the Warrant Stock until the end of the applicable lockup period. 14. Transfers. Subject to the terms and conditions contained in --------- Section 13 hereof, this Warrant and all rights hereunder are transferable in whole or in part by the Holder and any successor transferee; provided, however, that in no event shall the total number of transfers of any of the rights and interests in all of the Warrant exceed five (5) transferees. The transfer shall be recorded on the books of the Company upon receipt by the Company of a notice of transfer in the form attached hereto as Exhibit B (the "Transfer Notice"), at its principal offices, and the payment to the Company of all transfer taxes and other governmental charges imposed on such transfer. The Transfer Notice shall also be accompanied with an opinion of counsel reasonably satisfactory in substance to the Company that the transfer will not (i) violate any provision of the Act and any applicable state securities laws or (ii) cause the Company to 19 lose the exemption from registration under applicable federal and state securities laws used for the original issuance of this Warrant. 15. Legend. Each certificate representing Warrant Stock or any other ------ security issued or issuable upon exercise of this Warrant shall bear the following legend, unless counsel for the Company is of the opinion as to any such certificate that such legend is unnecessary: The securities represented by this certificate may not be offered for sale, sold or otherwise transferred except pursuant to an effective registration statement made under the Securities Act of 1933 (the "Act"), or pursuant to an exemption from registration under the Act. 16. Applicable Law. This Warrant shall be governed by, and construed -------------- in accordance with, the laws of the State of Michigan. Date: _________________, 199__ AASTROM Biosciences, Inc.
