CONFIDENTIAL TREATMENT HAS BEEN REQUESTED FOR THE REDACTED PORTIONS OF THIS EXHIBIT, AND SUCH CONFIDENTIAL PORTIONS HAVE BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.

EXTENDED COLLABORATION AND LICENSE AGREEMENT

This Extended Collaboration and License Agreement(the “Agreement”) is made and entered into as of January 1, 2006 (the “Effective Date”), by and betweenAthersys, Inc., a Delaware corporation having its principal offices at 3201 Carnegie Avenue, Cleveland, Ohio 44115 (“Athersys”), andBristol-Myers Squibb Company, a Delaware corporation having offices at Route 206 and Province Line Road, Princeton, New Jersey 08543 (“BMS”). Athersys and BMS may be referred to herein individually as a “Party” and collectively as the “Parties.”

Recitals

A. Athersys has developed and owns technology and intellectual property rights relating to methods for activating gene or protein expression in cells, referred to by Athersys as the Random Activation of Gene Expression or RAGE technology, which includes the RAGE-VT technology useful for creating cell lines that express particular desired proteins.

B. BMS desires to engage Athersys to create certain such cell lines, using the RAGE-VT technology, each of which expresses a specific cell surface or cellular protein of interest to BMS, and to obtain license rights to use such cell lines for internal research, development and commercialization of pharmaceutical products.

C. Athersys is willing to create and provide BMS with the desired cell lines pursuant to the terms of this Agreement.

D. The Parties entered into a Research Collaboration and License Agreement, dated December 8, 2000 (the “Original Agreement”) and subsequently entered into a Cell Line Collaboration and License Agreement dated July 1, 2002 (the “Prior Agreement”), each related to the creation of cell lines by Athersys for use by BMS.

E. Concurrently with entering into this Agreement, Athersys and BMS are amending the Prior Agreement to acknowledge that BMS has fulfilled its obligation to propose and accept a minimum number of cell lines as set forth in the Prior Agreement.

F. For avoidance of doubt, all cell lines nominated by BMS after July 1, 2002 and prior to the Effective Date of this Agreement shall be governed by the Prior Agreement and all cell lines nominated by BMS prior to July 1, 2002 shall be governed by the Original Agreement and not this Agreement. All cell lines nominated by BMS after the Effective Date of this Agreement shall be governed by this Agreement.

Now, Therefore, in consideration of the foregoing and the covenants and promises contained in this Agreement, the Parties agree as follows:

Definitions

As used herein, the following capitalized terms shall have the following meanings (with terms defined in the singular having the same meanings when used in the plural):

1.1 “Accepted Cell Line”shall have the meaning assigned to such term in Section 2.3(a).

1.17 “License”shall have the meaning assigned to it in Section 3.2.

1.18 “Net Sales”shall mean the amount invoiced or otherwise billed by BMS or its Affiliate or licensee for sales or other commercial disposition of a Product to a Third Party purchaser, less the following to the extent included in such billing or otherwise actually allowed or incurred with respect to such sales: (i) discounts, including cash, trade and quantity discounts, price reduction programs, retroactive price adjustments with respect to sales of a product, charge-back payments and rebates granted to managed health care organizations or to federal, state and local governments (or their respective agencies, purchasers and reimbursers) or to trade customers, including but not limited to, wholesalers and chain and pharmacy buying groups; (ii) credits or allowances actually granted upon rejections or returns of Products, including for recalls or damaged goods; (iii) freight, postage, shipping and insurance charges actually allowed or paid for delivery of Products, to the extent billed; (iv) customs duties, tariffs, surcharges and other governmental charges incurred in connection with the exportation or importation of a Product; (v) bad debts relating to sales of Products that are actually written off by BMS in accordance with generally accepted accounting principles, consistently applied, during the applicable royalty calculation period, and (vi) taxes, duties or other governmental charges levied on, absorbed or otherwise imposed on sale of Products, including without limitation value-added taxes, or other governmental charges otherwise measured by the billing amount, when included in billing, as adjusted for rebates and refunds, but specifically excluding taxes based on net income of the seller; provided that all of the foregoing deductions are calculated in accordance with generally accepted accounting principles consistently applied throughout the party’s organization.

Notwithstanding the foregoing, if any Product is sold under a bundled or capitated arrangement with other BMS products, then, solely for the purpose of calculating Net Sales for royalty purposes hereunder, any discount on such Product sold under such an arrangement shall be no greater, on a percentage basis based on the gross selling price prior to discount, than the largest percentage discount applied on the other pharmaceutical products sold within such bundled

arrangement for the applicable accounting period. In case of any dispute as to the applicable discount numbers under the preceding sentence, the determination of same shall be calculated and certified by BMS’ independent public accountants, whose decision shall be binding.

A sale of a Product is deemed to occur upon the earliest of invoicing or transfer of title in the Product to the Third Party purchaser. In the event that BMS, after reasonable efforts, cannot calculate accurately the Net Sales of a sublicensee in a particular country, the Parties will meet and negotiate in good faith an appropriate means for calculating “Net Sales” in such a situation.

For sake of clarity and avoidance of doubt, sales by BMS, its Affiliates or sublicensees of a Product to a Third Party distributor of such Product in a given country shall be considered sales to a Third Party customer, but sales and/or transfers of a Product between or among BMS, its Affiliates or sublicensees shall not be considered sales to a Third Party customer, so long as such recipient subsequently resells the Product. Any Products used (but not sold for consideration) for promotional or advertising purposes or used for clinical or other research purposes shall not be considered in determining Net Sales hereunder.

In the event a Product is sold as an end-user product consisting of a combination of active functional elements or as a combined product and/or service, Net Sales, for purposes of determining royalty payments on such Product, shall be calculated by multiplying the Net Sales of the end-user product and/or service by the fraction A over A+B, in which A is the gross selling price of the Product portion of the end-user product and/or service when such Product is sold separately during the applicable accounting period in which the sales of the end-user product were made, and B is the gross selling price of the other active elements and/or service, as the case may be, of the end-user product and/or service sold separately during the accounting period in question. All gross selling prices of the elements of such end-user product and/or service shall be calculated as the average gross selling price of the said elements during the applicable accounting period for which the Net Sales are being calculated. In the event that, in any country or countries, no separate sale of either such above-designated Product or such above designated elements of the end-user product and/or service are made during the accounting period in which the sale was made or if gross retail selling price for an active functional element, component or service, as the case may be, cannot be determined for an accounting period, Net Sales allocable to the Product in each such country shall be determined by mutual agreement reached in good faith by the Parties prior to the end of the accounting period in question based on an equitable method of determining same that takes into account, on a country by country basis, variations in potency, the relative contribution of each active agent, component or service, as the case may be, in the combination, and relative value to the end user of each active agent, component or service, as the case may be.

Notwithstanding the foregoing, it is agreed that drug delivery vehicles, adjuvants, and excipients shall not be deemed to be “active ingredients” or “active functional elements,” the presence of which in a Product would be deemed to create a combination product subject to the terms of the preceding paragraph.

1.19 “Patents”shall mean all issued United States and foreign patents (including all reissues, extensions, renewals, substitutions, re-examinations, supplementary protection

certificates and the like, and patents of addition) and pending United States and foreign patent applications (including, without limitation, all provisional and nonprovisional applications and all continuations, continuations-in-part and divisions thereof).

1.20 “Product”shall mean any product containing a Candidate Compound, including any formulation, dosage form, packaged form or delivery means thereof.

1.21 “RAGE Technology”shall mean any and all intellectual property, whether or not patentable, that is owned or licensed by Athersys and relates to Athersys’ techniques for activating gene expression, which are referred to by Athersys collectively as Random Activation of Gene Expression or RAGE technology.

1.22 “Term”shall have the meaning assigned to it in Section 11.1.

1.23 “Third Party”means any entity other than Athersys, BMS or an Affiliate of either of them.

1.24 “Valid Claim”shall mean either (i) a claim of issued and unexpired letters patent which has not been held permanently revoked, unenforceable 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 that is not admitted to be invalid or unenforceable through reissue, disclaimer or otherwise, or (ii) a claim of a pending patent application that has not been pending for more than seven (7) years and that has not been abandoned or finally rejected without the possibility of appeal or refiling.

Collaboration Program

2.1 Review of Proposed Cell Lines by Athersys.

(a)Subject to the limits set forth in Section 2.2, Athersys shall create new Accepted Cell Lines based on RAGE-VT cell lines that BMS proposes, as set forth inExhibit A, and Athersys has accepted as provided below. BMS shall use reasonable, good faith efforts to assure that the aggregate level of technical difficulties and legal risks associated with the cell lines that BMS nominates is balanced and provides Athersys a reasonable opportunity to perform hereunder. Athersys shall have the right to review and approve, as provided inExhibit A, the target protein to be expressed in each RAGE-VT cell line that BMS proposes be made under this Agreement. Athersys shall complete such review within forty-five (45) days after the date Athersys receives information from BMS regarding a proposed target to be expressed in a RAGE-VT cell line, or upon any other schedule to which the Parties may mutually agree in writing. Athersys shall use reasonable, good faith efforts to assure that the aggregate level of technical difficulties and legal risks associated with the cell lines that Athersys accepts is balanced and provides a reasonable opportunity for the generation of Accepted Cell Lines hereunder.

(b)While Athersys is completing such review, the Parties shall promptly negotiate specific Acceptance Criteria for such cell line based upon the Acceptance Criteria as generically set forth inExhibit A. Upon agreement by the Parties on the specific Acceptance Criteria for a particular proposed RAGE-VT cell line, such Acceptance Criteria shall be included

inExhibit A, and, subject to review and subsequent approval of the target protein by Athersys under this Section 2.1, Athersys shall promptly thereafter commence work under Section 2.2 to create a RAGE-VT cell line based thereon, and any such cell line shall be a “Collaboration Cell Line.”

(c)If Athersys rejects any of the proposed RAGE-VT cell lines in accordance with the parameters set forth inExhibit A, Athersys shall promptly notify BMS, and BMS shall amendExhibit A in order to designate a replacement RAGE-VT cell line (for each one of the RAGE-VT cell lines originally proposed and rejected by Athersys) within sixty (60) days after receiving notice of the rejection; provided, however, that Athersys shall again have the right to review and approve any such proposed replacement cell line, as above.

(d)BMS shall be obligated to propose at least three (3), but not more than seven (7), RAGE-VT cell lines per year beginning on the Effective Date and ending on the third anniversary of the Effective Date. If Athersys rejects one or more cell lines subject to this Section 2.1, then BMS shall replace each rejected cell line with a new proposed cell line, until Athersys has at least 3 cell lines in the current year. BMS shall have sixty (60) days to replace each rejected cell line, regardless of the deadline for meeting any applicable minimum under this Section 2.1. For avoidance of doubt, any proposed cell lines in excess of the minimum in a given year may not be applied to future annual obligations.

2.2 Supply of Collaboration Cell Lines; Status Reports.Athersys shall use reasonable efforts to deliver to BMS each Collaboration Cell Line that Athersys approves under Section 2.1 within six (6) months after such approval. Athersys shall provide BMS with summary reports, which shall be written, of the status and progress of Athersys’s efforts to provide Collaboration Cell Lines every eight (8) weeks. Such reports shall be sent to the attention of the BMS Project Coordinator. Athersys shall not be obligated to supply to BMS more than a total of eight (8) Collaboration Cell Lines per year over the Term.

2.3 Review of Collaboration Cell Lines by BMS.

(a)BMS shall have the right, for a period of forty-five (45) days after receiving a particular Collaboration Cell Line, to review such Collaboration Cell Line for the purpose of evaluating whether or not the production of protein meets the specific Acceptance Criteria for the particular Collaboration Cell Line as agreed by the Parties (pursuant to Section 2.1) and set forth inExhibit A. Unless BMS provides written notice to Athersys that such Collaboration Cell Line does not meet such specific Acceptance Criteria within such period, such Collaboration Cell Line shall be accepted by BMS and shall be an “Accepted Cell Line” for all purposes hereunder. Even if any Collaboration Cell Line fails to produce the amount of protein meeting the specific Acceptance Criteria set forth inExhibit A, BMS shall nonetheless have the right, but not the obligation, to accept such Collaboration Cell Line as an Accepted Cell Line, by written notice to Athersys within such forty-five (45) day period. If BMS does not accept a Collaboration Cell Line, BMS and Athersys shall discuss the reason(s) such Collaboration Cell Line was not accepted, and if BMS and Athersys agree that modifying the approach to creating a Collaboration Cell Line is feasible and desirable, Athersys shall make such modification and present such modified Collaboration Cell Line to BMS for evaluation and acceptance (if applicable) as provided herein.

(b)Athersys shall provide the BMS Project Coordinator with at least two (2) weeks’ advance notice of Athersys’ intent to deliver a Collaboration Cell Line to BMS for review under Section 2.3(a), so that BMS may attempt to allocate internal resources appropriately. In the event Athersys fails to give such notice with respect to any given Collaboration Cell Line, the BMS review period therefor shall be extended to sixty (60) days.

2.4 Infringement by Accepted Cell Lines.If at any time during the term of the License or Counterscreening License applicable to a particular Accepted Cell Line, such Accepted Cell Line becomes, or in Athersys’ opinion is likely to become, the subject of a Third Party patent infringement claim based on BMS’ practice of such License or Counterscreening License, then Athersys shall use commercially reasonable efforts, at its sole expense, either (i) to procure for BMS the right to continue using such Accepted Cell Line, or (ii) to replace or modify such Accepted Cell Line so that it becomes noninfringing while still having substantially the same functionality and efficacy as prior to such replacement or modification. In the event Athersys is not successful in its efforts under clause (i) and/or (ii) of the preceding sentence within three (3) months after any such claim arises, Athersys shall, at BMS’s request, meet to discuss in good faith other possible solutions to the claim.

2.5 Selection of Counterscreening Cell Lines.As to a particular cell line that BMS requests to be made under Section 2.1, BMS may specify in writing, at the time the request for such cell line is made, that such cell line will be a Counterscreening Cell Line when accepted under Section 2.3, and such cell line then would be used solely for Counterscreening pursuant to the Counterscreening License. BMS may so specify no more than fifty percent (50%) of the Collaboration Cell Lines requested in a particular year be used for Counterscreening. For purposes of clarity, at any time subsequent to a cell line’s designation as a Counterscreening Cell Line, BMS may elect to initiate an HTS program with respect to such Cell Line, subject to the terms and conditions of this Agreement with respect to an Accepted Cell Line.

2.6 Project Coordinators.Each Party shall designate an individual (a “Project Coordinator”) to coordinate, on such Party’s behalf, the day-to-day interaction of and communication between the Parties under this Agreement. Each Project Coordinator shall possess the education, training and experience necessary to make him or her reasonably technically qualified to serve as a Project Coordinator. Each Party shall be free to replace its Project Coordinator with new a appointee who has authority to act on behalf of such Party, upon notice to the other Party.

2.7 BMS Diligence.BMS agrees that, for each Accepted Cell Line (but excluding all Counterscreening Cell Lines), BMS shall initiate and use reasonably diligent efforts to complete an HTS program for such Accepted Cell Line as soon as practicable after the date such cell line is designated or deemed an Accepted Cell Line. Notwithstanding the preceding sentence, an Accepted Cell Line shall be deemed to have completed HTS twelve (12) months after acceptance unless the Cell Line fails to perform as prescribed inExhibit A. BMS shall provide Athersys with reasonable reports regarding its progress in conducting such HTS screening.

2.8 BMS Termination of Cell Lines.

(a) Prior to Cell Line Acceptance.With respect to Collaboration Cell Lines for which acceptance has not yet occurred, upon thirty (30) days notice to Athersys, BMS may terminate Athersys’ development of any Collaboration Cell Line, provided that BMS has paid all milestones achieved prior to termination pursuant to Section 4.1(a) or 4.1(c), as the case may be, for each such Collaboration Cell Line.

(b) Following HTS Completion.With respect to any Accepted Cell Line (other than Counterscreening Cell Lines) for which HTS completion has occurred and BMS has paid the corresponding milestone payment under Section 4.1(a), upon thirty (30) days notice to Athersys, BMS may, for reasonable business, scientific and/or technical reasons (which shall be disclosed to Athersys, on a confidential basis), terminate its License with respect to such Accepted Cell Line, which termination shall be effective after payment of the next license fee due under Section 4.1(b). On the due date of such payment the license to such Accepted Cell Line granted under Section 3.2 shall automatically terminate, and after payment of such license fee BMS shall have no further payment obligations to Athersys with respect to such Accepted Cell Line subject to the following covenant. With respect to any such Accepted Cell Line for which BMS has terminated its license rights pursuant to this Section 2.8(b), BMS covenants that BMS and its Affiliates and licensees shall not use, develop or commercialize any materials, results, data or information (including, without limitation, any compound or composition, or any derivative, homolog or isomer thereof) that was originally created or originally identified through BMS’ prior use of such Accepted Cell Line; provided, however, that the foregoing covenant shall not preclude BMS and its Affiliates from continuing to conduct discovery, research, development and commercialization activities with respect to the target protein expressed by such Accepted Cell Line so long as BMS and its Affiliates abide by such covenant in so doing.

2.9 BMS Termination of Collaboration Program.BMS shall have the right to terminate the collaboration program contemplated by this Section 2 at the end of each year of the collaboration program, by giving Athersys written notice of such termination at least sixty (60) days prior to the anniversary of the Effective Date, provided that BMS has accepted an aggregate of at least fifteen (15) cell lines since July 1, 2002 (i.e., the effective date of the Prior Agreement). BMS acknowledges that Athersys will incur certain wind-down and FTE re- allocation costs and expenses in the event of any such early termination and, therefore, agrees to pay Athersys the sum of $125,000 to help offset such costs. Such payment shall be made within thirty (30) days after delivery of BMS’ termination notice pursuant to this Section 2.9.

Licenses.

3.1 Evaluation License.Subject to the terms of this Agreement, as to each Collaboration Cell Line provided to BMS by Athersys hereunder, Athersys grants to BMS a royalty-free, non-exclusive, worldwide license, without the right to sublicense, under the Athersys Technology solely to conduct internal research evaluation of such Collaboration Cell

Line as provided in Section 2.3 of this Agreement during the forty-five (45) day period after BMS first receives such Collaboration Cell Line.

3.2 Research and Development License.Subject to the terms of this Agreement, and effective upon BMS’s acceptance of a particular Accepted Cell Line (other than a Counterscreening Cell Line), Athersys grants to BMS a royalty-bearing, non-exclusive, worldwide license, without the right to sublicense, under the Athersys Technology solely to use such Accepted Cell Line in the Field (the “License”).

3.3 Counterscreening License.Subject to the terms of this Agreement, and effective only upon BMS’s acceptance of a particular Accepted Cell Line that BMS elected under Section 2.5 to be a Counterscreening Cell Line, Athersys hereby grants to BMS a non-exclusive, worldwide license (the “Counterscreening License”), without the right to sublicense, under the Athersys Technology solely to use each such Counterscreening Cell Line for Counterscreening. For clarity, a particular Accepted Cell Line may not be used by BMS (or its Affiliate) for use both in the Field and for Counterscreening except as specified in 4.1 (e).

3.4 Duration of Athersys Licenses.

(a) Field License Duration.The License granted in Section 3.2, as to a particular Accepted Cell Line, shall be perpetual, subject to payment of all applicable fees, unless terminated by BMS as provided in Section 2.8(b).

(b) Counterscreening License Duration.Subject to payment of all applicable fees, the Counterscreening License granted in Section 3.3 shall be perpetual, as to a particular Counterscreening Cell Line.

3.5 Negative Covenants.

(a) No Other Use by BMS.BMS covenants and agrees that it shall not use the Collaboration Cell Lines for any purpose other than as set forth in Section 3.1 and shall not use the Accepted Cell Lines or any materials derived therefrom for any purpose other than as set forth in Sections 3.2 and 3.3, as applicable. BMS further covenants and agrees that it shall not use or practice the Athersys Technology for any purpose except as expressly permitted in the licenses granted to BMS under Sections 3.1, 3.2 and 3.3, as applicable.

(b) No Transfer to Third Parties.BMS covenants and agrees that BMS shall not transfer Collaboration Cell Lines or Accepted Cell Lines or any Information pertaining thereto or any materials derived therefrom, to any Third Party for any purpose, except that BMS may transfer such Information and materials to collaborators to the extent necessary for BMS to exercise its right to use the Accepted Cell Lines in connection with bona fide collaborations with academic and/or commercial partners in the Field, but may not transfer the Accepted Cell Lines to such entities except with Athersys’ prior written consent. For clarity, BMS covenants and agrees that BMS shall not transfer Collaboration Cell Lines or Accepted Cell Lines, or any Information pertaining thereto or any materials derived therefrom, to any Third Party for Counterscreening.

3.6 Athersys Reserved Rights.BMS understands and agrees that Athersys owns and reserves to itself all rights, title and interest in the Athersys Technology, and to the Collaboration Cell Lines and the Accepted Cell Lines, subject only to the licenses granted in Sections 3.1, 3.2 and 3.3, respectively.

3.7 Records And Reports.

(a) Records.BMS shall maintain complete and accurate records that fully and properly reflect all work done and all results achieved, including raw data, in the evaluation of Collaboration Cell Lines, the use of Accepted Cell Lines and the discovery, research and development of Candidate Compounds (“Records”). The Records shall be kept with sufficient detail and in good scientific manner appropriate for patent and regulatory purposes and shall be kept separate and distinct from other work conducted by BMS, all in a manner consistent with BMS’ other internal research and development record keeping.

(b) Copies and Inspection of Records.Athersys shall have the right, during normal business hours and upon reasonable notice, to inspect the Records for purposes consistent with this Agreement. Athersys shall maintain all Information learned from such inspection of the Records in confidence in accordance with Article 7. All inspections, copying and visits hereunder shall be conducted in a manner and frequency so as not to disrupt BMS’s business and in a manner so as not to cause any disclosure of any other BMS Confidential Information.

(c) Semi-Annual Reports.Within thirty (30) days following the end of each six (6) month period during the term of the License with respect to each Accepted Cell Line, BMS shall provide to Athersys a written progress report that shall describe the results and developments of the use of such Accepted Cell Line, and the discovery, research and development of Candidate Compounds therewith. With such reports, BMS shall disclose to Athersys in summary form (i.e.,in a manner that does not require BMS to disclose sensitive or competitively-enabling data or information) the development, making, conception or reduction to practice of all Candidate Compounds that are discovered, made, investigated, conceived or reduced to practice by use of such Accepted Cell Line or assays based thereon. In addition, BMS shall fully disclose to Athersys in each such report any Improvements that BMS may have developed during the period covered by such report.

The indemnifying Party shall have the sole right to control the defense and settlement thereof. The indemnifying Party shall have the right to settle or compromise any Liabilities for which it is providing indemnification under this Article 10, provided that the consent of the Indemnitee (which shall not be unreasonably withheld or delayed) shall be required in the event any such settlement or compromise would adversely affect the interests of such Indemnitee. The Indemnitees shall cooperate with the indemnifying Party and its legal representatives in the investigation of any action, claim or liability covered by this Article 10. The Indemnitees shall not, except at their own cost, voluntarily make any payment or incur any expense with respect to any claim or suit without the prior written consent of the indemnifying Party, which the indemnifying Party shall not be required to give.

11.

Term and Termination.

11.1 Term of Agreement.The term of this Agreement (the “Term”) shall commence on the Effective Date and continue until expiration upon the end of all royalty and payment obligations of BMS under Article 4, or until such earlier date as the Parties agree in writing to terminate the Agreement or the Agreement terminates as provided below.

11.2 Termination for Cause.Either Party may terminate this Agreement in the event the other Party has materially breached or defaulted in the performance of any of its obligations hereunder, and such default has continued without cure for sixty (60) days after written notice thereof was provided to the breaching Party by the non-breaching Party. Any termination shall become effective at the end of such sixty (60) day period unless the breaching Party has cured any such breach or default prior to the expiration of the sixty (60) day period. Notwithstanding the above, in the case of a failure to timely pay any amounts due hereunder, the period for cure of any subsequent default following notice thereof shall be thirty (30) days and, unless payment is made within such period the termination shall become effective at the end of such period.

11.3 Effect of Termination.

(a) Accrued Rights and Obligations.Termination of this Agreement for any reason shall not release any Party hereto from any liability which, at the time of such termination, has already accrued to the other Party or which is attributable to a period prior to such termination nor preclude either Party from pursuing any rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement. It is understood and agreed that monetary damages may not be a sufficient remedy for any breach of this Agreement and that the non-breaching Party may be entitled to injunctive relief as a remedy for any such breach.

(b) Return of Confidential Information.Upon any termination of this Agreement, each of Athersys and BMS shall promptly return to the other Party all Confidential Information of the other; provided that counsel of each Party may retain one (1) copy of such Confidential Information solely for archival purposes.

Exhibit A

RAGE-VT CELL LINES

A.Creation of Collaboration Cell Lines

Within ninety (90) days after the Effective Date, BMS shall provide Athersys with an initial list of specific proteins for which BMS requests that Athersys will create RAGE libraries, for Athersys’ review under Section 2.1(a). If Athersys accepts such proposed proteins as provided therein, Athersys shall seek to create RAGE libraries, and screen and isolate Collaboration Cell Lines expressing such proteins after the Parties agree upon Acceptance Criteria for each particular Collaboration Cell Line. Such list may be supplemented from time to time by mutual agreement of the Parties or by designation of additional specific proteins by BMS and acceptance of such proteins by Athersys, as provided in Section 2.1 and in accordance with the procedure provided below.

From time to time, BMS may nominate specific proteins for consideration by Athersys under Section 2.1 for use in constructing a Collaboration Cell Line using its RAGE technology and other Athersys Know-How. Any such Collaboration Cell Line shall conform to the general specifications set forth in Section B below and to any other specific requirements agreed to by the Parties.

Athersys shall have the right, before accepting such request of a particular protein by BMS hereunder, to review and approve the technical and intellectual property feasibility of constructing the requested Collaboration Cell Line. If requested by Athersys, BMS shall promptly provide to Athersys the relevant technical requirements of BMS for the requested Collaboration Cell Line. Athersys shall make its determination of technical feasibility, intellectual property analysis and/or conflict with preexisting exclusive research obligations to Third Parties or preexisting internal research programs for which research has commenced prior to receiving notice (a “Pre-existing Program”), within forty-five (45) days of the request by BMS. If Athersys believes that the project is not constrained by any of these considerations or fails to provide any such notice within such forty-five (45) day period, then the nominated protein (and corresponding Collaboration Cell Line) shall be deemed to be added to thisExhibit A. If Athersys believes the project is constrained by any of such considerations and provides such notice within such forty-five (45) day period, such protein and cell line shall not be added toExhibit A; provided that Athersys shall provide to BMS all pertinent information Controlled by Athersys regarding the basis for its rejection of such request. In that event, BMS shall be entitled to nominate another protein (with the foregoing process being repeated), until a protein nominated by BMS hereunder is accepted by Athersys. For purposes of calculating the maximum number of cell lines permitted under this Agreement, any substitute request made by BMS shall be deemed to have been made as of the date of the original request.

In addition, in the event Athersys commences a Pre-existing Program with respect to a target (either internally or with a Third Party), and BMS subsequently proposes such target under Section 2.1, Athersys shall promptly inform BMS of such program and request that BMS propose a substitute target. In such event, Athersys shall, upon BMS’ request, provide, on a confidential basis, a reasonable demonstration of such commencement and prosecution of any

such Pre-existing Program for a given target prior to the date of BMS’ proposal of such target under Section 2.1.

B.Acceptance Criteria for Collaboration Cell Lines

The Parties shall discuss and agree upon a set of specific Acceptance Criteria for each Collaboration Cell Line based upon the Generic Criteria set forth below. Such Acceptance Criteria shall be deemed to constitute a part of thisExhibit A. In each case, BMS and Athersys shall agree upon one primary assay (with respect to each Collaboration Cell Line, the “Primary Assay”) as the determining criterion for optimization and proof of target over-expression for purposes of determining whether a particular Collaboration Cell Line satisfies various of its Acceptance Criteria. If BMS wishes to have receptor density as determined by radioligand binding (which may require MTX amplification) as an acceptance criterion, BMS may specify not more than fifty percent (50%) of the Collaboration Cell Lines in a particular year, for such acceptance treatment. If BMS wishes Athersys perform multiple assay validation and/or make radioligand binding determinations in addition to those specified in the preceding sentence, BMS shall bear the additional cost thereof.

Generic Collaboration Cell Line Acceptance Criteria


		Testing to determine if

As used in thisExhibit B, the phrase “Initiation of first Phase III clinical study” shall be deemed to include, if a party conducts a Phase II/III study on a Candidate Compound, the point during such Phase II/III clinical trial when the party conducting the trial has the regulatory approval to proceed with such trial as a pivotal trial.

BMS shall promptly notify Athersys of the first occurrence of any milestone with respect to each Candidate Compound. Milestone payments shall be made only once with respect to any given Candidate Compound, regardless of the number of indications sought (or approvals obtained) with respect to such Candidate Compound, whether alone or in combination with other compounds or products, and regardless of any new dosage strengths, preparations or forms of administration for such Candidate Compound.

If BMS develops as a back-up Candidate Compound that inhibits or otherwise modulates the activity of a particular molecular target of a Candidate Compound on which BMS is already making milestone payments, then BMS may conduct clinical development on such back-up or follow-on Candidate Compounds and shall not be obligated to make any milestone payments with respect to any such back-up or follow-on Candidate Compound, except as otherwise provided below. In the event that a particular Candidate Compound is dropped from active clinical development work or marketing for safety or efficacy reasons and is specifically replaced with a different Candidate Compound targeting the same molecular target as such dropped Candidate Compound, such new Candidate Compound shall be deemed a “Replacement Compound.” BMS shall not be obligated to make milestone payments that were earlier made with respect to a dropped Candidate Compound and replaced by a Replacement Compound, but, subject to the preceding paragraph, BMS shall pay all milestone payments for milestone events achieved by such Replacement Compound that had not been achieved by such dropped Candidate Compound.

Athersys Extends Partnership With Bristol-Myers Squibb To Provide Drug Targets

Cleveland, January 6, 2006 - Athersys Inc. announced today that it has extended its existing alliance with Bristol-Myers Squibb Company (NYSE: BMY) to apply its patented RAGE technology to provide Bristol-Myers Squibb with additional validated drug targets for high-throughput screening and lead optimization in multiple therapeutic areas. The new agreement will extend the alliance for up to three years with a guaranteed minimum number of targets to be supplied by Athersys annually. Under the terms of the extension, Athersys is entitled to receive license fees for targets delivered to Bristol-Myers Squibb, as well as milestone payments and royalties on compounds developed by Bristol-Myers Squibb using the Athersys technology.

The collaboration extension builds upon an on-going partnership and two previous agreements between the companies. Athersys and Bristol-Myers Squibb originally entered into a research and development collaboration in January 2001 and then expanded the collaboration in July 2002. Over the course of the partnership, Athersys has successfully delivered multiple drug targets to Bristol-Myers Squibb from distinct target classes and in a variety of therapeutic areas. These targets provide the foundation for several active drug development programs at Bristol-Myers Squibb. As part of the extended partnership, the companies will continue to work closely together to facilitate certain drug development activities at Bristol-Myers Squibb.

“Athersys is delighted to continue our long-standing partnership with Bristol-Myers Squibb," said John Harrington, Ph.D., Executive Vice President and Chief Scientific Officer of Athersys. "During the past several years, Athersys has continued to refine its proprietary technologies and provide our partners with access to important validated drug targets. This collaboration extension represents an important financial transaction for the company, and provides further validation for the technological foundation of our internal drug development programs.”

About RAGE

RAGE (Random Activation of Gene Expression) is a novel gene expression system developed by Athersys scientists that provides the unique ability to produce protein from virtually any gene in the human genome, without requiring the cloning of individual genes or use of cDNA libraries. The technology may be used to facilitate the mapping of complex biological pathways using genome-wide protein expression libraries produced using RAGE in conjunction with cell based assays, or may be used as a means to produce cell lines that express individual drug targets of interest.
