CONFIDENTIAL

Notwithstanding the foregoing and subject to Section 9.5, any payments owed with respect to sales of Licensed Products in a country in the Territory pursuant to this Section 9.3 shall be reduced by [*] percent ([*%]), such reduction to be prorated appropriately for the then-current Pfizer Quarter, for Net Sales occurring during any time there is either no Valid Claim or no right of data or market exclusivity covering such Licensed Product in the Field in such country in the Territory. The parties agree and acknowledge that the payment of royalties by PFIZER to ATHERSYS for sales in a country in which there is no Valid Claim or no right of data or market exclusivity covering the applicable Licensed Product in the Field shall represent consideration for the license to Athersys Technology, Athersys Combination Product IPRs, and Athersys Confidential Information granted by ATHERSYS to PFIZER in Sections 7.1.

9.4 Sales Milestone Payments Credit against Royalty Payments.

[*] percent ([*%]) of each Sales Milestone Payment (each a “Sales Milestone Credit”) shall be credited against future payments under Section 9.3. PFIZER shall reduce the royalty payments due in respect of the next Pfizer Quarter by the amount of the applicable Sales Milestone Credit. To the extent any Sales Milestone Credit cannot be fully credited by reducing the amount of the royalty payments due in respect of that next Pfizer Quarter, the royalty payments due in respect of subsequent Pfizer Quarters shall be reduced by any remaining amount until the applicable Sales Milestone Credit has been fully credited.

9.5 Duration of Royalty Payments.

Payments under Section 9.3 in respect of Net Sales for a Licensed Product in the Field in a country in the Territory shall continue until the expiration of the Royalty Term in that country for such Licensed Product in the Field; thereafter, the licenses granted under Section 7.1 with respect to such Licensed Product in such country shall be royalty-free and fully paid up, perpetual and irrevocable.

Section 10 ACCOUNTING AND PROCEDURES FOR PAYMENT.

10.1 Inter-Company Sales.

Sales between or among PFIZER, its Affiliates or sub-licensees shall not be subject to royalties under Section 9. Instead, only the first sale by PFIZER or its Affiliates or sublicensees to a Third Party shall be used to calculate the Net Sales upon which the royalty calculation is based. PFIZER shall be responsible for the payment of royalties on Net Sales by its Affiliates or sublicensees to Third Parties.

10.2 Currency.

All royalty payments shall be computed and paid in United States dollars. For the purposes of determining the amount of any Sales Milestone Payments or royalties due for the relevant Pfizer Quarter, the amount of Net Sales in any foreign currency shall be converted into United States dollars in a manner consistent with PFIZER’S normal practices used to prepare its audited financial reports; provided that such practices use a widely accepted source of published exchange rates.

CONFIDENTIAL

10.3 Royalty Payments.

(a) PFIZER shall make royalty payments to ATHERSYS with respect to each Pfizer Quarter, within sixty (60) days after the end of each calendar quarter, and each payment shall be accompanied by a report identifying the applicable Pfizer Quarter for each Licensed Product in the Field: (i) each applicable country or, for those countries where PFIZER does not typically produce a country-specific report, the applicable region in which Net Sales occurred; (ii) the gross sales for the Licensed Product in each such country or such region; (iii) the Net Sales for the Licensed Product for each such country or such region; (iv) the applicable royalty rate for the Net Sales for the Licensed Product in each such country or such region; and (v) the amount of royalties payable to ATHERSYS for the Licensed Product in each such country or such region, as well as the computation thereof. Said reports shall be kept confidential by ATHERSYS and not disclosed to any other party, other than ATHERSYS’s accountants which shall be obligated to keep such information confidential, and such information and reports shall only be used for purposes of this Agreement.

(b) If Net Sales in any Pfizer Quarter during a given Pfizer Year are less than zero (as a result of returns or recalls of Licensed Product in the Field or any other circumstance), then PFIZER will not be obligated to pay ATHERSYS any royalties for such Pfizer Quarter, and for purposes of calculating royalty payments with respect to the fourth Pfizer Quarter of such Pfizer Year, Net Sales for such fourth Pfizer Quarter shall be reduced by the aggregate amount of negative Net Sales in each Pfizer Quarter of such Pfizer Year in which Net Sales are less than zero. If, as a result of such reduction, the aggregate Net Sales with respect to such fourth Pfizer Quarter are less than zero, then, for purposes of calculating royalty payments with respect to the first or subsequent Pfizer Quarters of the next succeeding Pfizer Year, Net Sales for such first Pfizer Quarter and until any negative Net Sales have been fully exhausted any subsequent Pfizer Quarters shall be reduced by the amount of negative Net Sales in the fourth Pfizer Quarter of the immediately preceding Pfizer Year.

10.4 Method of Payments.

Each payment hereunder shall be made by electronic transfer in immediately available funds via either a bank wire transfer, an ACH (automated clearing house) mechanism, or any other means of electronic funds transfer, at PFIZER’s election, to such bank account as ATHERSYS shall designate in writing to PFIZER at least five (5) Business Days before the payment is due.

10.5 Inspection of Records.

PFIZER shall, and shall cause its Affiliates and sublicensees to, keep accurate books and records setting forth the, gross sales of each Licensed Product in the Field, Net Sales of each such Licensed Product, amounts payable hereunder to ATHERSYS for each such Licensed Product and other information reasonably required to verify the calculation of payments made under Section 10.3 and Schedule 3.2(c), provided that nothing in this Section 10.5 shall require PFIZER to keep or create books, records or reports solely for the purpose for this Section 10.5 or which PFIZER would not typically keep for the purpose

CONFIDENTIAL

of determining and reporting royalties or profit sharing arrangements. PFIZER shall permit ATHERSYS, by independent certified public accountants employed by ATHERSYS and reasonably acceptable to PFIZER, to examine such books and records at any reasonable time, upon reasonable notice, but not later than two (2) years following the rendering of the corresponding reports pursuant to Section 10.3 and Schedule 3.2(c). The foregoing right of examination may be exercised only once during each twelve (12)-month period of the Term and once during the two (2) year period after the Term. PFIZER may require such accountants to enter into a reasonably acceptable confidentiality agreement, and in no event shall such accountants disclose to ATHERSYS any information, other than such as relates to the accuracy of the corresponding reports pursuant to Section 10.3 and Schedule 3.2(c). The opinion of said independent accountants regarding such reports and related payments shall be binding on the parties, other than in the case of manifest error. ATHERSYS shall bear the cost of any such examination and review; provided that if the examination shows an underpayment of royalties of more than five percent (5%) of the amount due for the applicable period, then PFIZER shall promptly reimburse ATHERSYS for all costs incurred in connection with such examination. PFIZER shall promptly pay to ATHERSYS the amount of any underpayment of royalties revealed by an examination. Any overpayment of royalties by PFIZER revealed by an examination shall be fully-creditable against future royalty payments under Section 9.3.

Upon the expiration of the two (2) year period following the rendering of a royalty report pursuant to Section 10.3, such report shall be binding on the parties, and PFIZER and its Affiliates shall be released from any liability or accountability with respect to royalties for the period covered by such report.

10.6 Tax Matters.

It is understood and agreed between the parties that any payments made by PFIZER under this Agreement are inclusive of any value added or similar tax imposed upon such payments. In addition, in the event any payments made by PFIZER pursuant to this Agreement become subject to withholding taxes under the laws or regulation of any jurisdiction, PFIZER shall deduct and withhold the amount of such taxes for the account of ATHERSYS to the extent required by applicable Law or regulations; such amounts payable to ATHERSYS shall be reduced by the amount of taxes deducted and withheld; and PFIZER shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to ATHERSYS an official tax certificate or other evidence of such tax obligations together with proof of payment from the relevant Governmental Authority of all amounts deducted and withheld sufficient to enable ATHERSYS to claim such payment of taxes. Any such withholding taxes required under applicable Law or regulations to be paid or withheld shall be an expense of, and borne solely by ATHERSYS . PFIZER will provide ATHERSYS with reasonable assistance to enable ATHERSYS to recover such taxes as permitted by applicable Law or regulations.

11.1 Prosecution.

ATHERSYS will be responsible for filing, prosecuting and maintaining the Athersys Patent Rights, at its own cost and expense. ATHERSYS shall consult and reasonably cooperate with PFIZER with respect to any potentially patentable inventions within the Research Program IPRs and Athersys Combination Product IPRs, including with respect to the content and timing of filing any draft patent applications thereon. ATHERSYS shall consult with PFIZER regarding countries in which to file any Athersys Patent Rights that (i) are based upon Research Program IPRs or Athersys Combination Product IPRs, or (ii) are other Athersys Patent Rights that are, at the relevant time, licensable or sublicensable for commercial purposes exclusively by ATHERSYS or its Affiliates, and that claim, or are reasonably likely to claim, inventions applicable to Licensed Products for use in the Field (such Athersys Patent Rights under (i) and (ii) collectively, “Athersys Exclusive Patent Rights”), and that are to be filed subsequent to the Effective Date. ATHERSYS shall promptly notify PFIZER of any new Athersys Patent Rights that are, or any Athersys Patent Rights existing as of the Effective Date that become, Athersys Exclusive Patent Rights under subsection (ii) of the preceding sentence.

11.2 Updates and Cooperation.

ATHERSYS will keep PFIZER informed of the status of the Athersys Patent Rights from time to time and in any event promptly on PFIZER’s reasonable request, and will provide PFIZER with copies of all substantive documentation submitted to, or received from, the patent offices in connection with the Athersys Exclusive Patent Rights. With respect to any substantive submissions that ATHERSYS is required to, or otherwise intends to, submit to a patent office, or any material decision relating to prosecution of the Athersys Exclusive Patent Rights, ATHERSYS shall provide a draft of such submission to PFIZER or inform PFIZER of such intended decision, reasonably in advance of the deadline or of the intended filing date of such submission or such decision effective date, for submission of such documentation. PFIZER shall have the right to review and comment upon any such submission by ATHERSYS, or any intended decision, to a patent office and will provide such comments, if any, reasonably in advance of the applicable deadline, intended filing date or decision effective date.

11.3 Maintenance.

ATHERSYS shall maintain, for the full life thereof, all patents under the Athersys Patent Rights unless ATHERSYS, in its reasonable discretion decides otherwise for commercial reasons. ATHERSYS will notify PFIZER of any decision not to file applications or any decision (i) not to file applications for, or not to enter the national phase for a PCT patent application, or validate a patent in a particular country, or (ii) to cease prosecution and/or maintenance of, or cease to pay the expenses of prosecution or maintenance of, any Athersys Exclusive Patent Rights in any country. ATHERSYS will provide such notice as soon as reasonably possible after its decision with respect to any of the foregoing, and sufficiently before (a) any date on which it must offer the right to prosecute to Angiotech, any licensor or any other party, and (b) any filing or payment due date or any other due date that requires action to avoid abandonment of or loss of right to file the patent or application, to enable PFIZER to consult with ATHERSYS regarding such decision and to undertake any action it may be entitled to take hereunder, in connection with such Athersys Exclusive Patent Rights. In such event, PFIZER shall, subject only to any rights granted to Angiotech prior to the Effective Date, and any limitations in any relevant in-licenses, have the right to make the filing, or to continue the prosecution and maintenance of such Athersys Exclusive Patent Rights at its expense, provided that (x) with respect to Athersys Exclusive Patent Rights which are Research Program IPRs, ATHERSYS shall assign, free of charge, such Athersys Exclusive Patent Rights to PFIZER and (y) with respect to any Athersys Exclusive Patent Rights included in Schedule 1.83 such Athersys Exclusive Patent Rights shall no longer be part of that Schedule.

CONFIDENTIAL

11.4 Notices.

ATHERSYS agrees that it will, and will cause its Affiliates to, (i) execute and file those notices and other filings as PFIZER shall request be made to record the existence of the rights granted hereunder, from time to time with the United States Patent and Trademark Office (or any successor agency) or any analogous patent office in the Territory, to the extent such filings are permitted in accordance with applicable Laws.

11.5 Patent Term Extensions.

PFIZER, subject to any rights granted to Angiotech prior to the Effective Date, shall have the exclusive right, but not the obligation, to seek, in ABT’s name if so required, patent term extensions, and supplemental protection certificates and the like available under Law, including 35 U.S.C. § 156 and applicable foreign counterparts, in any country in the Territory in relation to the Athersys Exclusive Patent Rights. ATHERSYS and PFIZER shall cooperate in connection with all such activities, and PFIZER, its agents and attorneys will give due consideration to all suggestions and comments of ATHERSYS regarding any such activities, but in the event of a disagreement between the parties, PFIZER will have final the final decision-making authority.

11.6 Third Party Royalty Obligations.

If PFIZER (a) reasonably determines in good faith that, in order to avoid infringement of any patent not licensed hereunder, it is reasonably necessary to obtain a license from a Third Party in order to make, use, sell, offer for sale, supply, cause to be supplied, or import a Licensed Product in the Field in a country in the Territory and to pay a royalty or other consideration under such license (including in connection with the settlement of a patent infringement claim), or (b) shall be subject to a final court or other binding order or ruling requiring any payments, including the payment of a royalty to a Third Party patent holder in respect of sales of any Licensed Product in the Field in a country in the Territory, then, without limiting ATHERSYS’ obligations under Section 17.1(a) (if any), the amount of PFIZER’s royalty payments under Section 9.3 with respect to Net Sales for such Licensed Product in such country shall be reduced by the amount payable by PFIZER to such Third Party, provided, however, that in no event will a deduction, or deductions, under this Section 11.6, in the aggregate, reduce any royalty payment made by PFIZER in respect of Net Sales of such Licensed Product pursuant to Section 9.3 in any Pfizer Year to less than [^*] percent ([*%]) of Net Sales of such Licensed Product for that Pfizer Year.

CONFIDENTIAL

11.7 Third Party Infringement.

(a) Each party will promptly notify the other in the event of any actual, potential or suspected infringement of a patent under the Athersys Patent Rights by any Third Party. Except as provided in Section 11.7(b) and 11.9, PFIZER shall have the sole right, but not the obligation, to institute litigation in connection with any infringement of the Athersys Exclusive Patent Rights in the Field, and any such litigation shall be at PFIZER’s expense, subject to ATHERSYS’ obligation to indemnify PFIZER for such expenses pursuant to Section 17 (if any); provided that any recoveries resulting from such action relating to a claim of a Third Party infringement, after deducting PFIZER’s out of pocket expenses (including counsel fees and expenses) in pursuing such claim, will be deemed Net Sales. If required in order to establish standing, ATHERSYS, upon request of PFIZER, agrees to timely commence or join in any such litigation, at PFIZER’s expense, and in any event to cooperate with PFIZER at PFIZER’s expense. The parties shall consult with respect to potential strategies for terminating such alleged or threatened infringement without litigation and PFIZER may not enter into settlements, stipulated judgments or other arrangements respecting such infringement without the prior written consent of ATHERSYS. No settlement, stipulated judgment or other voluntary final disposition of a suit under this Section 11.7 may be undertaken by PFIZER without the consent of ATHERSYS if such settlement, stipulated judgment or other voluntary final disposition would require ATHERSYS to be subject to an injunction, admit wrong-doing, make a monetary payment or would otherwise materially adversely affect ATHERSYS’ rights under this Agreement or any of the Athersys Exclusive Patent Rights.

(b) If PFIZER fails, pursuant to Section 11.7(a) to bring an action with respect to, or to terminate, the Third Party infringement prior to the earlier of (i) one hundred and eighty (180) days following the notice of alleged infringement; and (ii) ten (10) days before the time limit, if any, set forth in the applicable Laws for the filing of such actions, then ATHERSYS shall have the right, but not the obligation, to defend or institute litigation in connection therewith, and any such litigation shall be at ATHERSYS’ expense; provided that any recoveries resulting from such action relating to a claim of a Third Party infringement will be retained by ATHERSYS. PFIZER, upon request of ATHERSYS, shall cooperate with ATHERSYS at ATHERSYS’ expense, but shall be under no obligation to join in any such litigation. If PFIZER joins in such litigation, the parties shall consult with respect to potential strategies for terminating such alleged or threatened infringement without litigation. ATHERSYS may not enter into settlements, stipulated judgments or other arrangements respecting such infringement without the prior written consent of PFIZER if such settlement, stipulated judgment or other arrangement would require PFIZER to be subject to an injunction, admit wrong-doing, make a monetary payment or would otherwise conflict with the exclusive rights granted to PFIZER under this Agreement.

11.8 ANDA Filings.

If either party receives a notice under 21 U.S.C. §355(b)(2)(A)(iv) or 355(j)(2)(A)(vii)(IV) (“Paragraph IV Notice”) or any supplements or comparable provisions relating to biologic products (“ANDA Filing”) that are alleged to be equivalent to a Licensed Product in the Field and for which an Athersys Exclusive Patent Right is listed in the FDA’s Orange Book, then it shall provide a copy of such notice to the other party within two (2) Business Days after its receipt thereof. PFIZER shall have the only right, but no obligation, to initiate patent infringement litigation based on any ANDA Filing concerning any Athersys Exclusive Patent Rights in connection with the Field, at its own expense. In order to establish standing, ATHERSYS shall reasonably cooperate with PFIZER in any such litigation and shall timely commence or join in any such litigations, at PFIZER’s request and expense.

CONFIDENTIAL

11.9 Validity and Enforceability Challenges Concerning Athersys Exclusive Patent Rights.

Each party shall promptly notify the other in the event of any legal or administrative action by any Third Party involving an Athersys Exclusive Patent Right of which a party becomes aware, including any nullity, revocation, re-examination or compulsory license proceeding. In the event of an assertion of invalidity or unenforceability of Athersys Exclusive Patent Rights licensed hereunder, ATHERSYS shall promptly advise PFIZER in writing of such assertion and of all relevant facts and circumstances known to ATHERSYS pertaining to such assertion. Where such validity or enforceability assertion is made in connection with a litigation under Section 11.7 or 11.8, or in a declaratory judgment action where a counterclaim for infringement is subsequently made by PFIZER or ATHERSYS pursuant to Section 11.7, the party controlling such litigation under Sections 11.7 or 11.8 shall have the right to control the defense of such assertion. In all other instances, both parties shall thereafter consult and cooperate fully to determine an appropriate course of action.

11.10 Compensation to Inventors/Third Party Licensing Athersys Patent Rights or Technology.

As between ATHERSYS and PFIZER, only ATHERSYS shall be responsible for any compensation and any other payments due to the inventors or Third Party Licensors of Athersys Patent Rights, Athersys Technology or to the ATHERSYS inventors of any Research Program IPRs or Athersys Combination Product IPRs. As between ATHERSYS and PFIZER only PFIZER shall be responsible for any compensation,and any other payments due to the inventors or PFIZER’s licensors, of any Pfizer Technology or to the PFIZER inventors of any Research Program IPRs or Pfizer Combination Product IPRs.

(a) Subject to PFIZER’s right to control the defense of actions described in Sections 11.7, 11.8 and 11.9 (even where ATHERSYS is the Indemnifying Party), the Indemnifying Party shall have the right, exercisable by notice to the Indemnified Party within ten (10) Business Days after receipt of notice from the Indemnified Party of the commencement of or assertion of any Third Party Claim, to assume direction and control of the defense, litigation, settlement, appeal or other disposition of the Third Party Claim (including the right to settle the claim solely for monetary consideration) with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party; provided that (i) the Indemnifying Party has sufficient financial resources, in the reasonable judgment of the Indemnified Party, to satisfy the amount of any adverse monetary judgment that is sought, (ii) the Third Party Claim seeks solely monetary damages and (iii) the Indemnifying Party expressly agrees in writing that as between the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall be solely obligated to satisfy and discharge the Third Party Claim in full (the conditions set forth in clauses (i), (ii) and (iii) above are collectively referred to as the “Litigation Conditions”).

CONFIDENTIAL

(d) Within ten (10) Business Days after the Indemnifying Party has given notice to the Indemnified Party of its exercise of its right to defend a Third Party Claim, the Indemnified Party shall give notice to the Indemnifying Party of any objection thereto based upon the Litigation Conditions. If the Indemnified Party reasonably so objects, the Indemnified Party shall continue to defend the Third Party Claim, at the expense of the Indemnifying Party, until such time as such objection is withdrawn. If no such notice is given, or if any such objection is withdrawn, the Indemnifying Party shall be entitled, at its sole cost and expense, to assume direction and control of such defense, with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party. During such time as the Indemnifying Party is controlling the defense of such Third Party Claim, the Indemnified Party shall cooperate, and shall cause its Representatives to cooperate upon request of the Indemnifying Party, in the defense or prosecution of the Third Party Claim, including by furnishing such records, information and testimony and attending such conferences, discovery proceedings, hearings, trials or appeals as may reasonably be requested by the Indemnifying Party. In the event that the Indemnifying Party does not satisfy the Litigation Conditions or does not notify the Indemnified Party of the Indemnifying Party’s intent to defend any Third Party Claim within ten (10) Business Days after notice thereof, the Indemnified Party may (without further notice to the Indemnifying Party) undertake the defense thereof with counsel of its choice and at the Indemnifying Party’s expense (including reasonable, out-of-pocket attorneys’ fees and costs and expenses of enforcement or defense). The Indemnifying Party or the Indemnified Party, as the case may be, shall have the right to join in (including the right to conduct discovery, interview and examine witnesses and participate in all settlement conferences), but not control, at its own expense, the defense of any Third Party Claim that the other Party is defending as provided in this Agreement.

(e) The Indemnifying Party shall not, without the prior consent of the Indemnified Party, enter into any compromise or settlement that commits the Indemnified Party to take, or to forbear to take, any action. The Indemnified Party shall have the sole and exclusive right to settle any Third Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent such Third Party Claim involves equitable or other non-monetary relief, but shall not have the right to settle such Third Party Claim to the extent such Third Party Claim involves monetary damages without the prior written consent of the Indemnifying Party. Each of the Indemnifying Party and the Indemnified Party shall not make any admission of liability in respect of any Third Party Claim without the prior consent of the other party, and the Indemnified Party shall use reasonable efforts to mitigate losses arising from the Third Party Claim.

CONFIDENTIAL

17.4 Disclaimer of Liability for Consequential Damages.

IN NO EVENT SHALL ANY PARTY OR ANY OF ITS RESPECTIVE AFFILIATES BE LIABLE UNDER THIS AGREEMENT FOR SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, WHETHER IN CONTRACT, WARRANTY, TORT, NEGLIGENCE, STRICT LIABILITY OR OTHERWISE, INCLUDING LOSS OF PROFITS OR REVENUE, SUFFERED BY PFIZER, ATHERSYS OR ANY OF THEIR RESPECTIVE REPRESENTATIVES, EXCEPT (A) TO THE EXTENT OF ANY SUCH DAMAGES PAID TO A THIRD PARTY IN CONNECTION WITH A THIRD PARTY CLAIM, AND (B) FOR PURPOSES OF INDEMNIFICATION PURSUANT TO THIS SECTION 17, IN THE EVENT OF AN INTENTIONAL AND WILFUL BREACH IN BAD FAITH OF ANY REPRESENTATION, WARRANTY, COVENANT OR AGREEMENT BY ATHERSYS OR PFIZER (AS THE CASE MAY BE) CONTAINED IN THIS AGREEMENT; PROVIDED THAT THIS SECTION SHALL NOT RELIEVE EITHER PARTY FROM ITS PAYMENT OBLIGATIONS UNDER THIS AGREEMENT. ADDITIONALLY, THE PARTIES ACKNOWLEDGE AND AGREE THAT, NOTWITHSTANDING THE DILIGENT EFFORTS OF THE PARTIES, THE ACTIVITIES TO BE CONDUCTED UNDER THE RESEARCH PROGRAM AND THE CLINICAL DEVELOPMENT PROGRAM ARE INHERENTLY UNCERTAIN, AND THAT THERE ARE NO ASSURANCES THAT A LICENSED PRODUCT WILL BE SUCCESSFULLY DEVELOPED AND COMMERCIALIZED.

17.5 SOLE REMEDY.

EXCEPT AS EXPRESSLY PROVIDED IN THIS AGREEMENT AND EXCEPT FOR ANY EQUITABLE REMEDIES THAT MAY BE AVAILABLE TO A PARTY, INDEMNIFICATION PURSUANT TO THIS SECTION 17 SHALL BE THE SOLE AND EXCLUSIVE REMEDY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER LEGAL THEORY) AVAILABLE TO ATHERSYS OR PFIZER FOR THE MATTERS COVERED THEREIN.

Section 18 GOVERNING LAW AND JURISDICTION

If such controversy or claim cannot be resolved by means of such negotiations during such period, then such controversy or claim shall be resolved by the United States District Court for the Southern District of New York or a local court sitting in New York, New York (collectively, the “Courts”).

FORM OF PRESS RELEASE

Athersys Enters into Global Agreement with Pfizer to Develop and Market MultiStem^® for the Treatment of Inflammatory Bowel Disease

—Athersys to Host Conference Call Today at 11:00 AM EST to Discuss Stem Cell Partnership—

CLEVELAND OH December 21, 2009 (BUSINESS WIRE) —Athersys, Inc. (NASDAQ: ATHX) announced today that it has entered into an agreement with Pfizer Inc. (PFE) to develop and commercialize MultiStem^® for the treatment of Inflammatory Bowel Disease (“IBD”). MultiStem is an investigational stem cell therapy currently in development by Athersys for several other conditions, including acute myocardial infarction, bone marrow transplant support, and ischemic stroke.

Under the terms of the agreement, Athersys will receive an up-front cash payment of $6 million from Pfizer, as well as research funding and support during the initial phase of the collaboration. In addition, Athersys is also eligible to receive milestone payments of up to $105 million upon the successful achievement of certain development, regulatory and commercial milestones. Pfizer will have responsibility for development, regulatory and commercialization and will pay Athersys tiered royalties on worldwide commercial sales of MultiStem IBD products. Alternatively, in lieu of royalties and certain commercialization milestones, Athersys may elect to co-develop with Pfizer and the parties will share development and commercialization expenses and profits/losses on an agreed basis beginning at phase III clinical development.

Inflammatory Bowel Disease is a group of inflammatory and autoimmune conditions that affect the colon and small intestine, typically resulting in severe abdominal pain, weight loss, vomiting and diarrhea. The most common forms of the disease include Ulcerative Colitis and Crohn’s disease, which are estimated to affect more than two million people in the U.S., major European countries and Japan. Chronic IBD can be a severely debilitating condition, and advanced cases may require surgery to remove the affected region of the bowel, and may also require temporary or permanent colostomy or iliostomy. In many cases, surgery does not achieve a permanent cure, and patients suffer a return of the disease.

“Pfizer is committed to the development of new medicines that have the potential to fundamentally improve the quality of clinical care in areas of need. We are delighted to work with Athersys to develop MultiStem for inflammatory bowel disease,” said ▇▇. ▇▇▇▇ ▇▇▇▇▇▇▇▇, Head of Pfizer Regenerative Medicine. “This is an innovative new area and our collaboration with Athersys represents a cornerstone of Pfizer’s stem cell and regenerative medicine strategy.”

CONFIDENTIAL

“We have been systematically evaluating potential partnering opportunities in multiple areas, and we believe that Pfizer represents the ideal partner for this program,” said ▇▇. ▇▇▇ Van Bokkelen, Chairman and Chief Executive Officer at Athersys. “Their longstanding global leadership in development and commercialization of new medicines, focus on best-in-class therapies, and their growing commitment to regenerative medicine provide a great foundation for working together.”

About MultiStem

MultiStem is a patented and proprietary cell therapy product consisting of a special class of stem cells that are obtained from the bone marrow of healthy, consenting adult donors, and which have the demonstrated ability to produce a range of factors, as well as form multiple cell types. MultiStem appears to promote tissue repair and healing in multiple ways, such as through the production of multiple therapeutic factors produced in response to signals of inflammation and tissue damage. Athersys believes that MultiStem represents a unique “off-the-shelf” stem cell product based on the apparent ability to deliver multiple mechanisms of therapeutic benefit, administration of the product without tissue matching or immunosuppression, and its capacity for large scale production. Athersys maintain rights to develop and commercialize MultiStem for areas outside of the Pfizer collaboration. In 2008 Athersys was awarded the Frost & ▇▇▇▇▇▇▇▇ North American Product Innovation of the Year Award for MultiStem, which cited the product as having best-in-class potential among stem cell and regenerative medicine technologies.

Conference Call Information

Athersys will hold a conference call today at 11:00 a.m. Eastern Time (8:00 a.m. Pacific Time) to discuss this announcement. To participate in the conference call, please call [Insert Dial-up information]. In addition, this call is being Webcast and can be accessed at Athersys’s website at ▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇.
