ARTICLE 2

GOVERNANCE

2.1 Joint Steering Committee.

(a) JSC Formation. Within [**] days following the Effective Date, the Parties shall form a joint steering committee composed of [**] representatives (one member should be the Alliance Manager (as defined below)) from each of AVEO and ASTELLAS (unless otherwise mutually agreed by the Parties) (the “JSC”) all of whom, except for the Alliance Manager, will have sufficient seniority and shall be employees within the applicable Party to make decisions arising within the scope of the JSC’s responsibilities (for example, it is the Parties’ understanding that, at the appropriate stage of Commercialization of Profit-Share Products in the JDCT hereunder, at least one (1) representative from each of AVEO UK and APEL, along with at least one (1) representative from each of AVEO US and AUS, shall be members of the JSC), and one (1) of whom will have alliance management responsibility (such representative, an “Alliance Manager”). The JSC shall be the executive committee responsible for the overall governance of the Parties’ Development, Manufacturing and Commercialization activities under this Agreement, including the activities of the JDC and the JCC. The JSC does not intend to actively participate in soliciting orders from customers directly resulting in sales, negotiating any contract or sale, or performing other significant services necessary for the consummation of any sale. Each of AVEO and ASTELLAS shall designate its JSC Committee representatives in writing to the other within [**] days after the Effective Date. Each of AVEO and ASTELLAS may change its representatives by written notice to the other, and an alternate member designated by either AVEO or ASTELLAS may serve temporarily in the absence of a permanent member of the JSC for such Party; provided, however, that each Party will ensure that at all times during the existence of the JSC, its representatives on the JSC are appropriate in terms of expertise and seniority for the then-current stage of Development, Manufacturing and Commercialization of Licensed Compounds, Licensed Products and Licensed Product Biomarkers. The JSC may from time to time establish project teams or subcommittees, in addition to the JDC, the JCC and the JMAC, to handle matters within the scope of its authority. With regard to such subcommittees, the Parties agree and acknowledge that a joint manufacturing committee (the “JMC”) shall be established promptly after the Effective Date to, among other things, review the manufacturing and supply issues set forth in Section 2.1(d)(iii), Article 4 and the Supply Agreements, and review, and submit to the JSC for JSC review and approval, budgets and forecasts of Manufacturing Costs.

(b) JSC Meetings and Procedures. The JSC shall convene its first meeting within [**] days after the Effective Date. Subsequently, JSC meetings shall be held regularly (but no less frequently than on a [**] basis). The JSC may also meet more frequently as and to the extent reasonably requested by either AVEO or ASTELLAS or if required to perform its role for initial discussion of any disputes in accordance with Section 2.6. If not otherwise mutually agreed upon, a meeting shall be held promptly after AVEO or ASTELLAS, as the requesting Party, delivers the written request. JSC meetings may be held in person or by videoconference or teleconference, as the AVEO and ASTELLAS JSC representatives may agree, except that at least [**] meetings per year shall be in person.

(iv) Licensed Products originally sold by KHK (or its Affiliate, Sublicensee or Distributor) in the KHK Territory may be imported and resold in the Licensed Territory, to ASTELLAS and AVEO’s detriment in that this would diminish sales of Licensed Products by AVEO US OR APEL (and their respective Affiliates, Sublicensees and Distributors) in the JDCT or by API (and its Affiliates, Sublicensees and Distributors) in the Royalty-Bearing Territory.

(b) ASTELLAS and AVEO shall take legally permissible and reasonable measures (in the opinion of their respective legal counsel) to prevent any such sales, to the full extent permitted by Applicable Law. This shall include that, as required under Section 4.12 and Section 4.13 of the KHK Agreement, each of ASTELLAS and AVEO shall (i) label Licensed Products to be sold by such Party as being for sale within the Licensed Territory (or a country thereof, as applicable), and (ii) refrain from selling Licensed Products to any entity such Party has reason to believe will resell quantities of Licensed Product in the KHK Territory. If, despite taking such reasonable measures, cross-territory resales between the Licensed Territory and the KHK Territory nevertheless occur, the Parties, as their sole remedy, shall discuss with each other and, if requested by either Party, together with KHK, in good faith and mutually agree on an equitable mechanism to compensate the party losing sales in the JDCT, the Royalty-Bearing Territory or the KHK Territory, as applicable.

(c) If cross-Territory resales nevertheless occur within the Licensed Territory, the Parties shall discuss with each other in good faith and mutually agree on an equitable mechanism to compensate the other Party losing sales in the JDCT or the Royalty-Bearing Territory, as applicable.

Information provided by an ASTELLAS contractor (or of an ASTELLAS contractor provided by ASTELLAS) to AVEO (including for access and use by KHK) and its Sublicensees under this Section 9.12(b) shall be the Confidential Information of ASTELLAS.

9.13 No Implied Licenses. Except as otherwise explicitly set forth in this Agreement, neither Party grants under its intellectual property (including Patents) any license, express or implied, to the other Party.

9.14 Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by either Party to the other are and shall be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101(52) of the Bankruptcy Code.

10.8 Third Party Payments – General Case.

(a) Payments to KHK. As between the Parties, AVEO shall remain responsible for any and all amounts payable to KHK under the KHK Agreement, provided that any amounts due to KHK under the KHK Agreement on account of regulatory milestones associated with North America and any royalties associated with sales of Licensed Products in North America shall be deducted for purposes of calculating N.A. Pre-Tax Profit or Loss.

(b) Payments to Third Parties (Excluding KHK) in JDCT. Subject to Section 9.9, if either Party is required to pay to a Third Party (excluding KHK) any amounts to Develop, Manufacture or Commercialize a Licensed Compound, Licensed Product or Licensed Product Biomarker in the Field for the JDCT under a license with such Third Party, then such amounts shall be shared equally by the Parties as Third Party Blocking IP Costs in the calculation of Pre-Tax Profit or Loss; provided that the Parties have mutually agreed to the terms pursuant to which such Party shall obtain such a license from such Third Party under Patents or Know-How owned or controlled by such Third Party that Covers such Licensed Compound, Licensed Product or Licensed Product Biomarker, or the Manufacture, use, sale or importation thereof.

(c) Payments to Third Parties (Excluding KHK) in Royalty-Bearing Territory. Subject to Section 9.9 and except as otherwise set forth in Section 10.9, API shall be responsible for obtaining any rights from Third Parties (excluding KHK) necessary to Develop, Manufacture (to the extent that API is responsible for performing packaging and labeling hereunder) or Commercialize any Licensed Compound, Licensed Product or Licensed Product Biomarker in the Field for the Royalty-Bearing Territory. If API is required to pay to any such Third Party royalties to Develop, Manufacture or Commercialize such Licensed Compound, Licensed Product or Licensed Product Biomarker in the Field for the Royalty-Bearing Territory under such license (including royalties which API may be required to pay to a Third Party under Section 10.9(a)(iii)), then API shall be entitled to credit against royalties payable to AVEO under Section 10.7 each quarter hereunder an amount equal to [**] percent ([**]%) of the royalties paid by API to such Third Party for such quarter. However, in no event shall royalties payable to

73

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

AVEO hereunder in respect of any calendar quarter be reduced by more than [**] percent [**]%) thereof.

10.9 Third Party Payments – Specific Case.

(a) If it becomes necessary for either Party or their respective Affiliates or Sublicensees to access patent rights claiming priority from [**] in order to make, use or sell a Licensed Product in the Licensed Territory (i.e., if it issues and covers the Licensed Product actually being commercialized, and withstands any challenge KHK or AVEO may choose to bring), then:

(i) ASTELLAS acknowledges that KHK will be responsible, [**], for taking a license thereunder (on an exclusive or non-exclusive basis) or another similar right (such as a covenant not to sue) and for sublicensing (or otherwise transferring such license to AVEO and/or ASTELLAS and their respective Affiliates or Sublicensees) in accordance with the terms of the KHK Agreement. Subject to consultation with ASTELLAS and JSC oversight, AVEO shall use Commercially Reasonable Efforts to enforce the provisions of Section 5.6 of the KHK Agreement against KHK if KHK fails to comply with aforementioned obligations under the KHK Agreement;

(ii) the Parties shall be jointly responsible for, and shall share equally as a Third Party Blocking IP Cost in the calculation of Pre-Tax Profit or Loss, any excess costs and expenses associated with such license or sublicense (i.e., costs and expenses that are not covered by KHK) to the extent that the rights obtained by KHK and sublicensed to either Party are necessary to Develop, Manufacture or Commercialize Profit-Share Products for use or sale in the JDCT, provided that ASTELLAS shall not have any obligation to pay such Third Party Blocking IP Cost if ASTELLAS has no opportunity to discuss, review or approve aforementioned rights obtained by KHK; and

(iii) API shall be solely responsible for any excess costs and expenses associated with such license or sublicense (i.e., costs and expenses that are not covered by KHK) to the extent that the rights obtained by KHK and sublicensed to API are necessary to Develop, Manufacture or Commercialize Royalty-Bearing Products for use or sale in the Royalty-Bearing Territory, subject to Section 10.8(c) above, provided that API shall not have any obligation to pay such costs and expenses if API has no opportunity to discuss, review or approve aforementioned rights obtained by KHK.

(b) To the extent that AVEO is notified by KHK of KHK’s intent to commence any formal challenge to any such patents, AVEO will notify ASTELLAS and the Parties shall reasonably cooperate with each other and with KHK to discuss and seek to reach a common understanding whether such challenge would be likely to have a material adverse effect on AVEO’s or ASTELLAS’s (or their respective Affiliates’ or Sublicensees’) ability to commercialize the Licensed Product in the Licensed Territory and the most sensible course of action weighing the relevant probabilities, costs and benefits.

74

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

10.10 Royalty Term. “Royalty Term” means, on a Licensed Product-by-Licensed Product and country-by-country basis, the time from the first post-Marketing Approval sale of such Licensed Product in such country in the Royalty-Bearing Territory until the later to occur of:

(a) the expiration of the last Valid Claim claiming or Covering the composition of the Licensed Product in the country in which such Licensed Product is sold;

(b) the expiration of the last Valid Claim claiming or Covering the use of the Licensed Product in the country in which such Licensed Product is sold (but only for so long as no Generic Competition exists in such country); or

(c) twelve (12) years after the first post-Marketing Approval sale of such Licensed Product in such country.

10.11 Combination Products. If API or its Affiliate or Sublicensee sells any Licensed Product in the Royalty-Bearing Territory as a combination product containing one or more active ingredients in addition to a Licensed Compound (which may be either combined in a single formulation or bundled with separate formulations) (“Combination Product”), Net Sales for such Combination Product shall be calculated by multiplying actual Net Sales of such Combination Product by the fraction A/(A+B) where A is the invoice price of the Licensed Compound thereof if sold separately, and B is the total invoice price of any other active ingredient or ingredients in the combination, if sold separately. If, on a country-by-country basis, the other active ingredient or ingredients in the combination are not sold separately in such country, Net Sales for the purpose of determining royalties of the Combination Product shall be calculated by multiplying actual Net Sales of such Combination Product by the fraction A/C where A is the invoice price of the Licensed Product if sold separately, and C is the invoice price of the Combination Product. If, on a country-by-country basis, neither the Licensed Compound nor the other active ingredient or ingredients of the Combination Product is sold separately in such country, or the mechanics provided above are otherwise inapplicable, Net Sales for the purposes of determining royalties of the Combination Product shall be determined by the Parties in good faith, based on the relative fair market values of the different active ingredients and in accordance with standard and customary practice if any, and in looking in particular to the relative list prices in other countries if available. If the immediately preceding sentence applies, API shall in good faith propose to AVEO a Net Sales allocation for such Combination Product based on the principles set forth in the immediately preceding sentence, such other Party shall in good faith consider such proposal, and the Parties shall seek to reach agreement on such allocation. If the Parties are unable to reach such agreement within sixty (60) days of API’s proposal, then the matter shall be referred for non-binding resolution to a mutually agreeable individual (not affiliated with either Party) having expertise in the research, development, marketing and sales of similar pharmaceutical products (including experience in pricing and reimbursement), such resolution to occur within sixty (60) days after such referral. Such individual shall be instructed to determine the Net Sales allocation for such Combination Product using the following standard: the allocation shall be made based on the relative fair market value contribution made by each of the different active ingredients contained in such Combination Product to its overall sales price, determined in accordance with standard customary practice (if

75

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

any), and looking in particular to the relative list prices in other countries, if available (the “Standard”). If either Party disagrees with the conclusions of such individual, then such Party shall refer the matter for resolution in accordance with Article 16. The standard to be applied in any arbitration of this allocation under Article 16 shall be the Standard (defined above in this Section 10.11).

10.12 Quarterly Payment Timings. All royalties due under Section 10.7 shall be paid quarterly, on a country-by-country basis, within [**] days after the end of the relevant calendar quarter for which royalties are due.

10.13 Royalty Payment Reports.

(a) Preliminary Reports. Within ten (10) days after the end of each calendar quarter (commencing with the first calendar quarter after commercial launch in the Royalty-Bearing Territory), API shall provide to AVEO a preliminary written report stating:

(i) Actual gross sales and deductions in the RBT for the first two (2) months of such calendar quarter, including:

(A) a statement of the amount of gross sales of Royalty-Bearing Products in the RBT during such two (2) month period;

(B) an itemized calculation of Net Sales (1) in the RBT as a whole and (2) on a country-by-country basis, showing for both (1) and (2) deductions provided for in the definition of “Net Sales” during such two (2) month period; and

(C) a calculation of the amount of royalty payment due on such Net Sales for such two (2) month period, less any amounts already remitted in accordance with Section 10.12 hereof; and

(ii) API’s good faith estimate of gross sales and deductions in the RBT for the last month of such calendar quarter, for financial reporting purposes.

(b) Final Reports. Within thirty (30) days after the end of each calendar quarter, API shall provide to AVEO a final written report stating:

(i) a statement of the amount of gross sales of Royalty-Bearing Products in the Royalty-Bearing Territory during such calendar quarter;

(ii) an itemized calculation of Net Sales (A) in the Royalty-Bearing Territory as a whole and (B) on a country-by-country basis, showing for both (A) and (B) deductions provided for in the definition of “Net Sales” during such calendar quarter; and

(iii) a calculation of the amount of royalty payment due on such Net Sales for such calendar quarter less any amounts already remitted in accordance with Section 10.12 hereof.

76

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

(c) Certain Requirements. Each report shall provide the information required on a country-by-country and Royalty-Bearing Product-by-Royalty-Bearing Product basis. Without limiting the generality of the foregoing, API shall require its Affiliates and Sublicensees to account for its Net Sales and to provide such reports with respect thereto as if such sales were made by API.

10.14 Payment Method. Except as otherwise provided in Section 10.17 regarding blocked currency, all payments due under this Agreement to a Party hereunder shall be made by bank wire transfer in immediately available funds to an account designated by such Party. All payments hereunder shall be made in the legal currency of the United States of America, and all references to “$” or “dollars” shall refer to United States dollars (i.e., the legal currency of the United States).

10.15 No Credits or Refunds. Except as otherwise explicitly stated in this Agreement, all payments to a Party hereunder shall be noncreditable and nonrefundable, except only to the extent that an audit conducted pursuant to Section 10.20 below confirms that a Party had overpaid amounts to the other Party, in which case such overpaid Party shall refund to the other Party the amount of such overpayment within thirty (30) days of receipt of an invoice therefor.

10.16 Taxes. The Party making a payment hereunder or otherwise incurring an obligation to withhold tax in respect of income allocable hereunder (the “Payor Party”) shall be responsible for and may withhold from payments made to the other Party (the “Payee Party”) under this Agreement any taxes required to be withheld by such Payor Party under Applicable Law. Any withholding taxes required to be paid by a Party with respect to income allocable to the other Party shall be remitted to the proper tax authorities at such time and in such manner as required by Applicable Law and, except as otherwise provided below, shall reduce the amounts otherwise payable to such other Party hereunder. If the amount of such taxes exceeds the amounts otherwise payable to such other Party hereunder, such other Party shall reimburse the first Party within ten (10) days of written demand therefor. If Payor Party is required to deduct and withhold taxes on any payment or income allocable to Payee Party and such withholding obligation arises as a result of any action by Payor Party that has the effect of modifying the tax treatment of the Parties (including any assignment or sublicense, or any failure on the part of Payor Party to comply with Applicable Law or filing or record retention requirements) (a “Withholding Tax Action”), then the sum payable by Payor Party (in respect of which such deduction or withholding is required to be made) shall be increased to the extent necessary to ensure that Payee Party actually receives the sum that it would have received had no such Withholding Tax Action occurred; provided, however, that no such increase shall apply to the extent such increase would have resulted (a) from a change in Applicable Law increasing the applicable withholding tax rate, which change occurs after the Effective Date, (b) in circumstances where actions or inactions of Payee Party or any of its Affiliates cause a change in the applicable withholding tax rate, for example, the failure of Payee Party to timely provide to Payor Party the appropriate treaty forms and the certificate of residence necessary for Payor Party to withhold at a more favorable rate or the assignment by Payee Party to an Affiliate or Third Party of the right to receive any payments hereunder or (c) from the failure of Payee Party to meet a limitation of benefits provision of the applicable tax treaty. Payor Party shall provide

77

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

to Payee Party evidence of the payment to the proper tax authorities of any taxes withheld or paid on behalf of Payee Party. For purposes of clarity, the Parties acknowledge that (x) with respect to N.A. Pre-Tax Profit or Loss, the relationship between AVEO US and AUS shall be considered a partnership for U.S. tax purposes, and that, as between the Parties, AVEO US shall be responsible for any filings required to be made in the U.S. in connection with such partnership, and (y) with respect to EU Pre-Tax Profit or Loss, the relationship between AVEO UK and APEL shall be considered a partnership for U.K. tax purposes, and that, as between the Parties, APEL shall be responsible for any filings required to be made in the U.K. in connection with such partnership.

10.17 Blocked Currency. In each country where the local currency is blocked and cannot be removed from the country, royalties and any other amounts accrued in that country shall be paid to the payee Party in the country in local currency by deposit in a local bank designated by such payee Party, unless the Parties otherwise agree.

10.18 Sublicenses. If either Party grants any sublicenses in the Licensed Territory under this Agreement, such sublicenses shall include an obligation for the Sublicensee to (a) maintain records adequate to document and verify the proper consideration (including royalties) to be paid to the licensor Party; (b) provide reports with each payment to the licensor Party sufficient to allow such verification; and (c) allow the licensor Party to conduct an audit as requested by the other Party to verify the proper payment of royalties, milestones and such Party’s share of Pre-Tax Profit or Loss, if applicable (such audit right is not required to be any stronger than that of Section 10.20).

10.19 Foreign Exchange. All payments to be made by one Party to the other Party under this Agreement shall be made in United States Dollars and may be paid by bank wire transfer in immediately available funds to such bank account in the United States as may be designated in writing by the Payee Party from time to time. In the case of sales or expenses outside the United States, the rate of exchange to be used in computing the amount of currency equivalent in United States Dollars shall be made using the average of the exchange rates for the purchase and sale of U.S. dollars, as published in Oanda.com for the last Business Day of the calendar quarter to which such payment pertains. With any payment in relation to which a currency conversion is performed to calculate the amount of payment due, the Payor Party shall provide to the Payee Party a true, accurate and complete copy of the Oanda.com exchange rates used in the calculation.

10.20 Records; Inspection.

(a) Each Party (the “Auditee”) shall keep and ensure that its Affiliates keep complete and accurate records of its Development, Manufacturing and/or Commercialization activities, as applicable, including sales and other dispositions (including use in clinical trials, or provision on a compassionate use basis or as marketing samples) of the Licensed Products and Licensed Product Biomarkers, including all such records that may be necessary for the purposes of calculating all payments due to the other Party (the “Auditing Party”) under this Agreement. The Auditee shall make such records available for inspection by an accounting firm selected by the other Party (the “Auditor”) under Section 10.20(c) at the Auditee’s or its Affiliates premises

78

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

where the relevant records are stored on reasonable notice during regular business hours (in accordance with the remaining provisions of this Section 10.20) no more than once in any calendar year.

(b) Upon timely request and at least thirty (30) Business Day’s prior written notice from the other Party, the Auditor shall be permitted to conduct such audit during regular business hours in such a manner as to not unnecessarily interfere with Auditee’s or its Affiliates’ normal business activities. Such audit shall be limited to results in any period that has not previously been audited under this Section 10.20, not to exceed [**] years prior to the audit notification.

(c) At the Auditing Party’s expense no more than once per calendar year, the Auditing Party has the right to retain an independent certified public accountant from a nationally recognized (in the U.S.) accounting firm (that is not an Affiliate of the Auditing Party) perform on behalf of the Auditor an audit, conducted in accordance with generally accepted auditing standards in the United States, of such books and records of the Auditee and its Affiliates as are deemed necessary by the independent public accountant to report on Net Sales, Pre-Tax Profit or Loss and any other amounts payable hereunder, for the period or periods requested by the Auditor and the correctness of any report or payments made under this Agreement (all subject to subsection (b)).

(d) In addition, each Party shall ensure that its Sublicensees keep complete and accurate records of such Sublicensee’s sales and other dispositions (including use in clinical trials, or provision on a compassionate use basis or as marketing samples) of the Licensed Products including all such records that may be necessary for the purposes of calculating all payments due under this Agreement. Each Party shall require that such Sublicensee make such records available for inspection by such Party, or an independent accounting firm selected by such Party, at least once during any calendar year in which the agreement between such Party and any Sublicensee is in effect and thereafter for a period of [**] years after the calendar year to which the audit pertains. Upon the reasonable request of the other Party with respect to any such Sublicensee, and no more than [**] in any calendar year, such Party shall exercise its audit rights with respect such Sublicensee and shall report the results of such audit to the other Party in accordance with Section 10.20(f).

(e) All information, data, documents and abstracts referred to in this Section 10.20 shall be used only for the purpose of verifying compliance with this Agreement, shall be treated as the Auditee’s Confidential Information subject to the obligations of this Agreement and need neither be retained more than [**] after completion of an audit hereof, if an audit has been requested; nor more than [**] years from the end of the calendar year to which each shall pertain; nor more than [**] years after the date of the expiration or termination of this Agreement.

(f) Audit results shall be shared between the Parties, and may be provided by AVEO to KHK. The Auditor shall be under written obligations to the Auditee (and, where applicable, any Sublicensee) of confidentiality and non-use (other than uses required by this Section 10.20) equivalent in scope to those set forth in Article 12 hereof.

79

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

(g) If the audit reveals an underpayment to the Auditing Party, the Auditee shall promptly pay to the Auditing Party the amount of such undisputed underpayment plus interest in accordance with Section 10.21. If the audit reveals that the undisputed monies owed by the Auditee to the Auditing Party has been understated by more than five percent (5%) for the period audited, the Auditee shall, in addition, pay the reasonable costs of such audit. If the audit reveals an undisputed overpayment to the Auditing Party, the amount of such overpayment shall be payable to the Auditee as provided in Section 10.15.

10.21 Interest. If either Party fails to make any payment due to the other Party under this Agreement, then interest shall accrue from the date the particular payment is due until paid at a rate equal to the Dollars prime or equivalent rate per annum quoted by The Wall Street Journal on the first Business Day after such payment is due, plus [**] percent ([**]%).

(iii) If API determines to abandon or not maintain any ASTELLAS Patent in the Licensed Territory, then API shall provide AVEO with at least thirty (30) days prior written notice of such determination (or such other period of time reasonably necessary to allow AVEO to assume such responsibilities). If AVEO requests, any such Patent solely owned (but not in-licensed or jointly-owned) by API shall be assigned to AVEO and, AVEO shall have the right, at its expense, to control the filing, prosecution and maintenance of it at its expense, without affecting any of the other financial terms set forth in this Agreement.

(c) Jointly Owned Product Patents. Subject to Section 11.8:

(i) With respect to each Joint Product Invention, as between AVEO and ASTELLAS, AVEO shall prepare, file, prosecute and maintain the corresponding Jointly Owned Product Patents in the JDCT, and API shall prepare, file, prosecute and maintain the corresponding Jointly Owned Product Patents in the Royalty-Bearing Territory. AVEO and API shall share equally in the prosecution and maintenance costs incurred by either Party with respect to Jointly Owned Product Patents in the JDCT and in the Royalty-Bearing Territory.

82

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

(ii) AVEO shall have the right to review and comment upon API’s prosecution and maintenance of Jointly Owned Product Patents in the Royalty-Bearing Territory, and API shall have the right to review and comment upon AVEO’s prosecution and maintenance of Jointly Owned Product Patents in the JDCT.

Furthermore, with respect to the preparation, filing, prosecution and maintenance of Jointly Owned Product Patents in the JDCT (if the Prosecuting Party is AVEO) or the Royalty-Bearing Territory (if the Prosecuting Party is API), the Prosecuting Party agrees to: (A) keep the other Party reasonably informed with respect to such activities; (B) consult with the other Party regarding such matters, including the final abandonment of any Jointly Owned Product Patent claims; and (C) reasonably consider the other Party’s comments.

(iii) If the Prosecuting Party determines to abandon or not maintain any Jointly Owned Product Patent in the JDCT (if the Prosecuting Party is AVEO), or the Royalty-Bearing Territory (if the Prosecuting Party is API), then such Prosecuting Party shall provide the other Party with at least sixty (60) days prior written notice of such determination (or such other period of time reasonably necessary to allow the other Party to assume such responsibilities). If the other Party requests, any such Patent shall be assigned to the other Party and, the other Party shall have the right, at its expense, to control the filing, prosecution and maintenance of the Patent that would otherwise have gone abandoned at its expense, without affecting any of the other financial terms set forth in this Agreement.

(d) Joint Other Invention Patents. With respect to each Joint Other Invention, AVEO and API shall confer and agree upon which Party shall prosecute or maintain the corresponding Joint Other Invention Patent. Either Party may disclaim its interest in any particular patent application or patent that is a Joint Other Invention Patent on thirty (30) days written notice to the other Party, in which case:

(i) the disclaiming Party shall assign its ownership interest in such Patent to the other Party for no additional consideration;

(ii) the Party that is then the sole owner shall be solely responsible for all future costs of such patent application or patent; and

(iii) the disclaiming Party shall hold no further rights thereunder.

(e) Certain Proceedings. For the purposes of this Section 11.2 and the definition of Patent and Trademark Costs, “prosecution” shall include defending the applicable Patents in proceedings such as oppositions, reexaminations, interferences, nullities or other administrative actions in which a Third Party contests the inventorship, validity, title or

83

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

enforceability of a Patent, provided, however, in the event there is conflict between this Section 11.2 and Section 11.4, or conflict between Sections 11.2 and 11.5, then Section 11.4 or Section 11.5 shall control.

(f) Affiliates/Sublicensees. API may grant to its Affiliates or Sublicensees all or certain of its rights with respect to the preparation, filing, prosecution and maintenance of Licensed Patents and ASTELLAS Patents, set forth in this Section 11.2, and AVEO may grant to its Affiliates and Sublicensees all or certain of its rights with respect to the preparation, filing and prosecution of the Listed AVEO Patents and AVEO Product Invention Patents set forth in this Section 11.2.

11.3 Patent Term Extensions.

(a) Discussion of Patent Term Extensions. AVEO and API shall discuss (with each other and, subject to Section 9.3(c), with KHK) and seek to reach mutual agreement for which, if any, of the Patents within the Licensed Patents, Jointly Owned Product Patents, and the ASTELLAS Patents, in each case in the Licensed Territory, the owner of record of the Patent in question shall apply to extend the patent term with respect to Licensed Products (and related Licensed Product Biomarkers), pursuant to patent term extension laws or regulations or Supplemental Protection Certificate laws and regulations in the Licensed Territory. ASTELLAS acknowledges that, KHK’s consent is required (in KHK’s sole discretion) for the extension of any Licensed Patent (as defined in the KHK Agreement) other than a License-Specific Licensed Patent (as defined in the KHK Agreement).

(b) Final Decision-Making Authority. If AVEO and API cannot reach agreement as to whether to apply to extend the term of a particular Patent in the Licensed Territory, then, subject to Section 11.8:

(i) Listed AVEO Patent: if the Patent is a Listed AVEO Patent, as between the Parties, AVEO shall have the right to make the final decision with respect to the JDCT, and API shall have the right to make the final decision with respect to the Royalty-Bearing Territory (which decision AVEO shall have the sole right and responsibility to seek to implement vis-à-vis KHK, subject to JSC oversight);

(ii) AVEO Product Invention Patent: if the Patent is an AVEO Product Invention Patent, as between the Parties, AVEO shall have the right to make the final decision with respect to the JDCT, and API shall have the right to make the final decision with respect to the Royalty-Bearing Territory;

(iii) ASTELLAS Patent: if the Patent is an ASTELLAS Patent, API shall have the right to make the final decision with respect to the Licensed Territory;

(iv) Jointly Owned Product Patent: if the Patent is a Jointly Owned Product Patent, AVEO shall have the right to make the final decision with respect to the JDCT, and API shall have the right to make the final decision with respect to the Royalty-Bearing Territory;

84

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

Provided that, in each of the foregoing cases, if API has the right to make the final decision with respect to extending the patent term for a Licensed Patent and determines to extend an ASTELLAS Patent in the Royalty-Bearing Territory (where applicable, if permitted under the agreement by which API obtained its license rights to such ASTELLAS Patent), but a Licensed Patent could have been extended instead, then claims in such Licensed Patent shall continue for purposes of determining all affected Royalty Terms to be deemed “Valid Claims” throughout the term of the extension that was available for the Licensed Patent, notwithstanding that they will have earlier expired.

11.4 Infringement of Patents by Third Parties.

(a) Notification. Each Party shall promptly notify the other Party in writing if the notifying Party reasonably believes that any Licensed Patent or ASTELLAS Patent is being or has been infringed or misappropriated in the Licensed Territory or the KHK Territory by a Third Party (such infringement, together with any that may be imminently threatened to occur by any potential generic version of a Licensed Product arising under the implementing procedures of 35 U.S.C. 271(e)(2) or ex-U.S. equivalent, “Infringement,” and “Infringe” shall be interpreted accordingly). In addition, AVEO shall promptly notify ASTELLAS in writing if AVEO receives any notice from KHK that any ASTELLAS Patent is Infringed in the KHK Territory.

(b) Competitive Infringement of Licensed Patents (Including Listed AVEO Patents, AVEO Product Invention Patents and Jointly Owned Product Patents).

(i) First Right. With respect to activities or conduct of a Third Party in the Field in the JDCT that compete with, or are expected to compete with, or otherwise materially affect the market for, Licensed Products in the Licensed Territory (“Competitive Infringement”), (A) AVEO shall have the first right, but not the obligation, to enforce the Listed AVEO Patents, AVEO Product Invention Patents and Jointly Owned Product Patents with respect to any such Competitive Infringement in the JDCT, and (B) API (or its Affiliate) shall have the first right, but not the obligation, to enforce the Listed AVEO Patents, AVEO Product Invention Patents and Jointly Owned Product Patents with respect to any such Competitive Infringement in the Royalty-Bearing Territory. The Party with the right to enforce under this Section 11.4(b)(i) (the “Enforcing Party”) shall reasonably consider the other Party’s comments on any such enforcement activities.

(ii) Back-up Right. If the Enforcing Party under subclause (i) above does not bring action to prevent or abate the Competitive Infringement in the JDCT (if AVEO is the Enforcing Party) or the Royalty-Bearing Territory (if API or its Affiliate is the Enforcing Party) within [**] days (or [**] Business Days in the case of an action brought under the Hatch-Waxman Act or any ex-U.S. equivalent of the Hatch-Waxman Act) after notification thereof to or by the other Party pursuant to Section 11.4(a), then, subject to Section 11.8, API (or its Affiliate) shall have the right, but not the obligation, to bring an appropriate action in the JDCT (if AVEO is the Enforcing Party), and AVEO shall have the right, but not the obligation, to bring an appropriate action in the Royalty-Bearing Territory (if API or its Affiliate is the Enforcing Party) against any Person engaged in such Competitive Infringement, whether direct or

85

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

contributory; provided, however, that such Party shall not initiate legal action without first conferring with the Enforcing Party and considering in good faith the Enforcing Party’s reasons for not bringing any such action.

(iii) Costs. The Parties shall share equally in the costs and expenses for enforcement of the foregoing Licensed Patents in the JDCT under this Section 11.4(b) (which costs and expenses, for purposes of clarity, shall be included as Patent and Trademark Costs in the calculation of Pre-Tax Profit or Loss), and, except as provided in Section 11.4(h), API shall bear all costs and expenses for enforcement of the foregoing Licensed Patents in the Royalty-Bearing Territory under this Section 11.4(b) (including the costs of the other Party’s cooperation as required under subsection (f)), provided, however, if AVEO exercises its back-up right under Section 11.4(b)(ii), then AVEO shall bear all costs and expenses for enforcement of the foregoing Licensed Patents in the Royalty-Bearing Territory under this Section 11.4(b) (including the costs of the other Party’s cooperation as required under subsection (f)).

(c) Competitive Infringement of ASTELLAS Patents. For purposes of clarity, API or its Affiliates shall have the sole right, but not the obligation, to enforce the ASTELLAS Patents with respect to any Competitive Infringement in the Licensed Territory. API and its Affiliates shall keep AVEO reasonably informed with respect to any such enforcement activities, and shall reasonably consider AVEO’s comments on any such enforcement activities, including conferring with AVEO with respect to any decision by API or the applicable Affiliate for not bringing any action to prevent or abate the Competitive Infringement in the JDCT.

(d) KHK Right to Enforce Certain Infringements. ASTELLAS acknowledges that KHK has certain rights (but not the obligation) under the KHK Agreement to enforce certain Licensed Patents with respect to activities or conduct of a Third Party in or for the Field outside the Licensed Territory or outside the Field worldwide, and with respect to certain Infringements in the Territory (other than a Competitive Infringement in the Licensed Territory), and that each of the Party’s rights and obligations with respect to enforcement of Licensed Patents hereunder shall be subject to such KHK rights.

(e) Third Party Infringement of Jointly Owned Product Patents and Joint Other Invention Patents. With respect to any Third Party Infringement of (i) Jointly Owned Product Patents anywhere in the Licensed Territory (other than a Competitive Infringement in the Licensed Territory), or (ii) Joint Other Invention Patents, the Parties shall confer with each other and take such action in such manner as they shall agree. If the Parties are unable after a reasonable period of time to agree on how to proceed, then each Party may, at its own cost and expense, exercise its rights as joint owner of the affected Joint Patent in accordance with the allocation of joint ownership rights as expressed in Section 11.1. If the Parties mutually agree on how to proceed in the JDCT, the Parties shall share equally in the costs and expenses for enforcement of the foregoing Patents in the JDCT under this Section 11.4(e) (which costs and expenses, for purposes of clarity, shall be included as Patent and Trademark Costs in the calculation of Pre-Tax Profit or Loss). Except as provided in Section 11.4(h), API shall bear all costs and expenses for enforcement of the foregoing Patents in the Royalty-Bearing Territory

86

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

under this Section 11.4(e) (including the costs of the other Party’s cooperation as required under subsection (f)).

(f) Participation of the Other Party with Respect to Infringement Suits. If a Party brings an action against infringement under Section 11.4(b) or Section 11.4(e), the other Party shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense, and such Party shall cooperate fully with the Party bringing such action including by being joined as a party plaintiff if necessary to obtain standing for such action (all at the expense on a pass-through basis of the prosecuting Party). ASTELLAS acknowledges that KHK has the right under the KHK Agreement to participate in any such action in accordance with the terms thereof.

(g) Settlement.

(i) AVEO shall not settle a claim brought under Section 11.4(b) or Section 11.4(e) involving Licensed Patents (including Jointly Owned Product Patents) in a manner that would limit or restrict the ability of ASTELLAS to sell Licensed Products for use in the Field in the Licensed Territory, impair the co-exclusivity of API’s rights hereunder with respect to the JDCT or the exclusivity of API’s rights hereunder with respect to the Royalty-Bearing Territory, or that would limit or restrict the ability of KHK to sell Licensed Products in the KHK Territory or for use outside the Field worldwide or impair the exclusivity of KHK’s rights under the KHK Agreement, in each case without the prior written consent of ASTELLAS (which consent shall not be unreasonably withheld, conditioned or delayed) and, if applicable, KHK.

(ii) ASTELLAS shall not settle a claim brought under Section 11.4(b), Section 11.4(c) or Section 11.4(e) involving Licensed Patents (including Jointly Owned Product Patents) or ASTELLAS Patents, as applicable, that would limit or restrict the ability of AVEO to sell Licensed Products in the JDCT, impair the co-exclusivity of AVEO’s rights hereunder with respect to the JDCT, or that would limit or restrict the ability of KHK to sell Licensed Products in the KHK Territory or for use outside the Field worldwide, or impair the exclusivity of KHK’s rights under the KHK Agreement, in each case without the prior written consent of AVEO (which consent shall not be unreasonably withheld, conditioned or delayed) and, if applicable, KHK.

(h) Allocation of Proceeds. If monetary damages are recovered from any Third Party in an action brought by a Party under Section 11.4(b) or Section 11.4(e) with respect to any Competitive Infringement or Infringement, as applicable, in the Licensed Territory, such recovery shall be allocated to the Parties as set forth below:

(i) first, to reimburse the Parties for any costs and expenses incurred by such Parties in such litigation (including, for this purpose, a reasonable allocation of expenses of internal counsel or other personnel acting in such capacity (i.e., coordination of litigation matters and the like)) to the extent not previously reimbursed and, solely to the extent required under Section 6.5(g) of the KHK Agreement, to reimburse KHK for costs and expenses incurred by KHK in such litigation; and

87

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

(ii) the portion of any remaining amounts after the allocation in clause (i) above that represents recovery for [**] shall be applied to KHK as follows:

(A) the portion of any such remaining amounts that represents recovery for [**] on any action brought under Section 11.4(b) above (1) to the extent [**], with the remaining portion of the [**] that does not represent treble or punitive damages being allocated to AVEO and ASTELLAS in accordance with clause (iii) below; and (2) to the extent [**] shall be allocated [**] percent ([**]%) to KHK and [**] percent ([**]%) to AVEO and ASTELLAS in accordance with clause (iii) below;

(B) the [**] on any action brought by KHK after exercising its back-up enforcement rights under Section 6.5(b)(ii) of the KHK Agreement shall be allocated to KHK in the same amount as under subclause (A) above that AVEO or ASTELLAS, as applicable, would have received if the action had been brought by AVEO or ASTELLAS, as applicable, under Section 11.4(b) above, with the [**] under this subclause (B) being allocated to AVEO and ASTELLAS in accordance with clause (iii) below;

(C) the portion of any such remaining amounts that represents recoveries in relation to lost sales of Licensed Products in the KHK Territory or of Licensed Products for use outside the Field in the Licensed Territory shall be allocated to KHK; and

(D) the portion of any such remaining amounts that represents recovery for Infringement in an action brought with respect to any Licensed Patents that fall within the definition of Jointly Owned Product Patents (as defined in the KHK Agreement) or Joint Other Invention Patents (as defined in the KHK Agreement) pursuant to Section 6.5(d) of the KHK Agreement shall be [**] percent ([**]%) to KHK and [**] percent ([**]%) to AVEO and ASTELLAS in accordance with clause (iii) below, unless KHK and AVEO agree in writing to a different allocation (which agreement AVEO shall not provide to KHK without ASTELLAS’s agreement on such terms); and

(iii) any remaining amounts after the allocation in clauses (i) and (ii) above shall be allocated [**] percent ([**]%) to the Party controlling such litigation and [**] percent ([**]%) to the other Party [**], and such remaining amounts after the allocation in clauses (i) and (ii) above shall be [**].

(i) Affiliates/Sublicensees. API may grant to its Affiliates or Sublicensees its rights to enforce Licensed Patents as set forth in this Section 11.4, and vice versa for AVEO and its Affiliates and its Sublicensees.

11.5 Infringement of Third-Party Rights. If any Licensed Product Manufactured, used or sold by AVEO or its Affiliates or Sublicensees becomes the subject of a Third Party’s claim or assertion of infringement of a Patent granted by a jurisdiction within the JDCT, or if any Licensed Product Manufactured, used or sold by ASTELLAS or its Affiliates or Sublicensees becomes the subject of a Third Party’s claim or assertion of infringement of a Patent granted by a jurisdiction within the JDCT or the Royalty-Bearing Territory, in each case relating to the Manufacture, use, sale, offer for sale or importation of Licensed Product, the Party first having

88

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

notice of the claim or assertion shall promptly notify the other Party, and the Parties shall promptly confer to consider the claim or assertion and the appropriate course of action. Unless the Parties otherwise agree in writing, each Party shall have the right to defend itself against a suit that names it as a defendant, subject to the indemnification provisions of Article 14. Neither Party shall enter into any settlement of any claim described in this Section 11.5 that affects the other Party’s rights or interests (or the rights or interests of KHK under the KHK Agreement) without such other Party’s (or KHK’s, if applicable) written consent, which consent shall not be unreasonably withheld or delayed. Any judgments, settlements, awards or other amounts received by either Party as a result of the defense of any such Third Party claim or assertion of Patent infringement within the JDCT shall be included as proceeds in the calculation of Pre-Tax Profit or Loss, and any Losses payable by either Party as a result of the defense of any such Third Party claim or assertion of Patent infringement within the JDCT shall be included as an Allowable Expense in the calculation of Pre-Tax Profit or Loss, in each case which shall be shared equally by the Parties. Any judgments, settlements, awards or other amounts received by API as a result of the defense of any such Third Party claim or assertion of Patent infringement within the RBT shall be [**], and any Losses payable by API as a result of the defense of any such Third Party claim or assertion of Patent infringement within the RBT shall be [**]. In any event, the Parties shall reasonably assist one another and cooperate in any such litigation at the other Party’s request and expense.

11.6 Patent Marking. ASTELLAS (or its Affiliate, Sublicensee or Distributor) shall mark Licensed Products (and related Licensed Product Biomarkers) marketed and sold by ASTELLAS (or its Affiliate, Sublicensee or Distributor) hereunder with appropriate Licensed Patent numbers or indicia at AVEO’s request to the extent permitted by Applicable Law, in those countries in which such notices affect recoveries of damages or equitable remedies available with respect to infringements of patents.

11.7 Patent Oppositions and Other Proceedings. If either Party desires to bring an opposition, action for declaratory judgment, nullity action, interference, reexamination or other attack upon the validity, title or enforceability of a Patent owned or controlled by a Third Party that covers or may cover the Manufacture, use for the Field or sale of any Licensed Product (or related Licensed Product Biomarker), such Party shall so notify the other Party. The Parties shall discuss in good faith the rationale for, and proposed actions to be taken, with respect to such opposition or other action.

11.8 In-Licensed Patents.

(a) ASTELLAS acknowledges and agrees that, without limiting the generality of Section 9.3, any rights granted to ASTELLAS under this Article 11 with respect to the prosecution or enforcement of Listed AVEO Patents, AVEO Product Invention Patents or other Licensed Patents (including the right to decide on matters related to patent term extensions) shall be subject to the following rights of, and obligations to, KHK under the KHK Agreement:

(i) Pursuant to Section 6.2(a) of the KHK Agreement, KHK shall have the first right and responsibility for filing, prosecution and maintenance of the Listed AVEO Patents and any other Licensed Patents that fall within the definition of Kirin Product Invention

89

(b) regulatory filings;

(c) prosecuting or defending litigation;

(d) complying with applicable governmental regulations or submitting information to tax or other governmental authorities, provided that if the receiving Party is required by Applicable Law to make any public disclosures of Confidential Information of the disclosing Party, to the extent it may legally do so, it will give reasonable advance notice to the disclosing Party of such disclosure and will use its reasonable efforts to secure confidential treatment of Confidential Information prior to its disclosure (whether through protective orders or otherwise);

(e) to (i) its Affiliates, and to prospective and actual licensees, Sublicensees, Distributors, acquirors, employees, consultants, agents, accountants, lawyers, advisors and investors, and (ii) others in order to (and solely to the extent required to) exercise such Party’s rights or fulfill its obligations under this Agreement or the KHK Agreement (including commercialization or sublicensing of Licensed Patents, Licensed Know-How or Licensed Products) on a need to know basis, each of whom in (i) and (ii) prior to disclosure must be bound by similar obligations of confidentiality and non-use substantially equivalent in scope to those set forth in this Article 12 and that are of reasonable duration in view of the circumstances of the disclosure; and

92

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

12.3 Publicity.

(a) The Parties have agreed to issue a joint press release in the form and with the content set forth on Exhibit J for the initial public announcement of the execution of this Agreement. Any other publication, news release or other public announcement by either Party regarding the execution or terms of this Agreement, shall first be reviewed and approved by the other Party, which approval shall not be unreasonably withheld, conditioned or delayed.

(b) In addition, each Party shall submit to the other Party for review and comment not less than five (5) Business Days in advance any significant public announcement regarding Licensed Compounds’, Licensed Products’ or Licensed Product Biomarkers’ performance and achievements hereunder or under the KHK Agreement and shall consider in good faith any comments made by the other Party therein. In case of any disclosure that is required by Applicable Law as reasonably advised by the disclosing Party’s counsel, such Party will provide the other Party with prompt notice of the required disclosure (but in any event no less than two (2) Business Days unless advised by legal counsel that more rapid disclosure is required under the circumstances), such other Party shall not be entitled to withhold consent, but the Parties shall find a mutually acceptable manner in which to make the disclosure. Permission to repeat information that has already been publicly disclosed shall not be required.

(c) The terms of this Agreement shall be treated as Confidential Information of both Parties; as between the Parties, the terms of the KHK Agreement shall be treated as Confidential Information of AVEO.

(i) Such terms may be disclosed by a Party to individuals or entities covered by Section 12.2(e)(i) (but not Section 12.2(e)(ii)), each of whom prior to disclosure shall be bound by similar obligations of confidentiality and non-use substantially equivalent in scope to those set forth in this Article 12.

(ii) Disclosure of the terms of this Agreement (but not other Confidential Information received from the other Party) may also be made, to actual or potential bankers, lenders, investors, acquirors, licensees, Sublicensees and Distributors of the disclosing Party, who are bound to obligations of confidentiality and non-use substantially equivalent in scope to those set forth in this Article 12; provided, however, that, ASTELLAS shall not be permitted to disclose the terms of the KHK Agreement.

(iii) In addition, if at any time the disclosing Party is legally required to file a copy of this Agreement with the Securities and Exchange Commission (“SEC”) (or its counterpart in any country other than the U.S.) in connection with any public offering of such Party’s securities or regular reporting obligations as a public company, such Party shall attempt to obtain confidential treatment of economic and trade secret information for which such treatment is reasonably available in accordance with Applicable Laws and SEC practice. To that end, the filing Party shall, at least thirty (30) days in advance of any such filing, provide the other Party with a draft set of redactions to this Agreement for which confidential treatment will be sought, and incorporate the other Party’s comments as to additional terms it would like to see

93

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

redacted, and seek confidential treatment for such additional terms (except only in the limited circumstances where confidential treatment is manifestly unavailable).

(iv) The Parties acknowledge that AVEO is required under Section 7.4 of the KHK Agreement to obtain KHK’s prior approval (not to be unreasonably withheld, conditioned or delayed) with respect to any publication, news release or public announcement regarding the terms of the KHK Agreement, to use good faith efforts to notify KHK in advance of any significant public announcement regarding Licensed Products’ performance and achievement, and, if either Party is required to file a copy of this Agreement with the SEC, to provide KHK, at least thirty (30) days in advance of such filing, with a draft set of redactions to this Agreement (as it relates to the KHK Agreement) for which any confidential treatment will be sought, and to incorporate KHK’s comments as to additional terms KHK would like to see redacted, and seek confidential treatment for such additional terms (except only in the limited circumstances where confidential treatment is manifestly unavailable). ASTELLAS shall reasonably cooperate with AVEO with respect to AVEO’s efforts to comply with the foregoing obligations to KHK under the KHK Agreement.

12.4 Publications.

(a) Neither Party shall first publish or first present in a public forum the scientific or technical results of any activities performed pursuant to this Agreement without the opportunity for prior review by the other Party. Each Party agrees to provide the other Party the opportunity to review any proposed abstracts, manuscripts or scientific presentations (including verbal presentations) which relate to its activities performed pursuant to this Agreement or to any Licensed Compound, Licensed Product or Licensed Product Biomarker at least thirty-five (35) days prior to their intended submission for publication and agrees, upon request, not to submit any such abstract or manuscript for publication until the other Party is given a reasonable period of time to secure patent protection for any material in such publication which it or they believe to be patentable. The Parties understand that a reasonable commercial strategy may require delay of publication of information or filing of patent applications first. The Parties agree to review and decide whether to delay publication to permit filing of patent applications. If the other Party offers no comments on the Publication, the submitting Party may submit the Publication thirty-five (35) days after it provided the Publication to the reviewing Party (or earlier, with the written consent of the reviewing Party). The submitting Party shall consider the comments of the reviewing Party in good faith. If the Parties are unable to agree upon any aspect of the Publication, including its form, content, timing (including with respect to additional time required for seeking patent protection for inventions disclosed in the Publication), or proposed medium of publication, either Party may refer the dispute to the JMAC, which shall resolve the dispute in accordance with Section 2.6. Neither Party shall have the right to publish or present Confidential Information of the other Party without the prior approval of the other Party. Nothing contained in this Section 12.4 shall prohibit the inclusion of information necessary for a patent application, provided the non-filing Party is given a reasonable opportunity to review the information to be included prior to submission of such patent application and to request deletion of its Confidential Information (subject to Section 12.2(a)).

94

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

(b) The Parties acknowledge that AVEO is required under Section 7.5 of the KHK Agreement to provide KHK with an opportunity to review any proposed abstracts, manuscripts or scientific presentations (including verbal presentations) which relate to development or commercialization activities under this Agreement or any Licensed Product, at least thirty (30) days prior to their intended submission for publication, and to not submit any such abstract or manuscript for publication until KHK is given a reasonable period of time to secure patent protection for any material in such publication which it believes to be patentable. ASTELLAS shall reasonably cooperate with AVEO with respect to AVEO’s efforts to comply with the foregoing obligations to KHK under the KHK Agreement.

101

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

(iii) The Parties acknowledge that, pursuant to Section 9.3 of the KHK Agreement, if AVEO and KHK cannot agree as to the application of Section 9.1 or Section 9.2 of the KHK Agreement as to any particular ASTELLAS Third-Party Claim (which agreement shall not be given or withheld by AVEO unless and until the Parties mutually agree to do so, such agreement not to be unreasonably withheld, delayed or conditioned by either Party), AVEO and KHK may conduct separate defenses of such ASTELLAS Third-Party Claim. In such case, as between AVEO and ASTELLAS, AVEO shall have the exclusive right to assume the defense of such ASTELLAS Third-Party Claim, including any settlement thereof (provided that AVEO shall not enter into any settlement for damages other than monetary damages without ASTELLAS’s written consent, which shall not be unreasonably withheld, delayed or conditioned), and ASTELLAS shall have the right to participate in such defense, at ASTELLAS’s own expense and using counsel of ASTELLAS’s own choice. The Parties acknowledge that AVEO reserves the right, and shall use Commercially Reasonable Efforts, to claim indemnity from KHK in accordance with Section 9.2 of the KHK Agreement upon resolution of the underlying ASTELLAS Third-Party Claim.

14.3 Product Liability Claims in the JDCT. Any Losses arising out of any Third Party claim, suit, action, proceeding, liability or obligation involving any actual or alleged death or bodily injury arising out of or resulting from the Development, Manufacture or Commercialization of any Licensed Compounds, Licensed Products or Licensed Product Biomarkers for use or sale in the Field in the JDCT, to the extent that such Losses exceed the amount (if any) covered by the applicable Party’s product liability insurance (“Excess Product Liability Costs”), shall be shared equally by the Parties as a Product Liability Cost for purposes of calculating Pre-Tax Profit or Loss, except to the extent such Losses arise out of any Third-Party Claim based on (a) a Party’s breach of any of its representations, warranties, covenants or obligations pursuant to this Agreement, the Supply Agreements or the JDCT Commercialization Agreement, or (b) the negligence or willful misconduct of a Party, its Affiliates, its or its Affiliates’ Sublicensees, or any of the respective officers, directors, employees and agents of each of the foregoing entities, in the performance of obligations or exercise of rights under this Agreement, the Supply Agreements or the JDCT Commercialization Agreement.

14.4 Procedure. To be eligible to be indemnified hereunder, a Party shall provide the indemnifying Party with prompt notice of the Third-Party Claim giving rise to the indemnification obligation pursuant to this Article 14 and the exclusive ability to defend (with the reasonable cooperation of the indemnified Party, at the defending Party’s expense on a pass-through basis) or settle any such claim; provided, however, that the indemnifying Party shall not enter into any settlement for damages other than monetary damages without the indemnified Party’s written consent, such consent not to be unreasonably withheld, delayed or conditioned. The indemnified Party shall have the right to participate, at its own expense and with counsel of its choice, in the defense of any claim or suit that has been assumed by the indemnifying Party. If the Parties cannot agree as to the application of Sections 14.1 and 14.2 to any particular Third Party Claim, the Parties may conduct separate defenses of such Third Party Claim. Each Party reserves the right to claim indemnity from the other in accordance with Sections 14.1 and 14.2 above upon resolution of the underlying claim, notwithstanding the provisions of this Section

102

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

14.4 requiring the indemnified Party to tender to the indemnifying Party the exclusive ability to defend such claim or suit.

14.5 Insurance. Each Party shall procure and maintain insurance or self-insurance, including product liability insurance, which are consistent with normal business practices of prudent companies similarly situated, at all times during which any Licensed Product is being clinically tested in human subjects or commercially distributed or sold by or on behalf of such Party. At a minimum, prior to the first Marketing Approval in the JDCT (with respect to AVEO and ASTELLAS) or the Royalty-Bearing Territory (with respect to ASTELLAS), such Party shall be insured for [**] U.S. dollars (US$[**]) to cover its obligations under this Agreement. After Marketing Approval, each Party shall be insured for a minimum of [**] U.S. dollars (US$[**]) to cover its obligations under this Agreement. It is understood that such insurance or self-insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 14. Each Party shall provide the other with written evidence of such insurance or self-insurance upon request. Each Party shall provide the other with written notice at least thirty (30) days prior to the cancellation, non renewal or material change in such insurance or self-insurance which materially adversely affects the rights of the other Party hereunder.

14.6 Limitation of Liability. EXCEPT TO THE EXTENT SUCH PARTY MAY BE REQUIRED TO INDEMNIFY THE OTHER PARTY UNDER THIS ARTICLE 14 OR IN RESPECT OF A BREACH OF ARTICLE 12, NEITHER PARTY NOR THEIR RESPECTIVE AFFILIATES AND LICENSEES (INCLUDING SUBLICENSEES) SHALL BE LIABLE FOR SPECIAL, INCIDENTAL, EXEMPLARY, CONSEQUENTIAL OR PUNITIVE DAMAGES, INCLUDING LOST PROFITS, ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT, WHETHER IN CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY OR OTHERWISE.

ARTICLE 15

TERM AND TERMINATION

15.1 Term; Expiration.

(a) Term. This Agreement shall become effective on the Effective Date and shall continue (i) with respect to the JDCT as a whole, until the expiration of all payment obligations hereunder associated with the JDCT, or (ii) with respect to the Royalty-Bearing Territory, on a country-by-country and Licensed Product-by-Licensed Product basis, until the expiration of the Royalty Term for such Licensed Product in such country in the Royalty-Bearing Territory, unless this Agreement is earlier terminated pursuant to this Article 15 (the “Term”).

(b) Expiration.

(i) Upon expiration of this Agreement as set forth in clause (a) above with respect to Licensed Compounds, Licensed Products and Licensed Product Biomarkers in the JDCT, or with respect to a particular Licensed Compound, Licensed Product or Licensed Product Biomarker in a particular country in the Royalty-Bearing Territory, as the case may be,

103

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

the licenses to API pursuant to Section 9.1 and licenses to the JDCT Trademark with respect to such Licensed Compounds, Licensed Products or Licensed Product Biomarkers shall automatically become, with respect to such Licensed Compounds, Licensed Products and Licensed Product Biomarkers in the JDCT or such country(ies) in the Royalty-Bearing Territory, as applicable, freely sublicensable, perpetual, non-exclusive, and fully paid.

(ii) Unless this Agreement is earlier terminated as provided in this Article 14, the licenses granted by ASTELLAS to AVEO pursuant to Section 9.4 shall survive until the expiration of this Agreement with respect to all Licensed Compounds, Licensed Products and Licensed Product Biomarkers, at which time they shall automatically convert to become freely sublicensable, perpetual, non-exclusive, and fully paid.

15.2 Elective Termination. ASTELLAS shall have the right, in its sole discretion, to terminate this Agreement (i) in its entirety or (ii) with respect to the whole of the Royalty Bearing Territory while retaining rights to the JDCT, by providing not less than one hundred eighty (180) days prior written notice to AVEO, which notice may be given at any time after the second (2nd) anniversary of the Effective Date.

15.3 Termination for Breach.

(a) Notice; Cure. If either AVEO or ASTELLAS believes that the other is in material breach of this Agreement or the JDCT Commercialization Agreement, then the non-breaching Party (AVEO or ASTELLAS, as the case may be) may deliver written notice of such breach to the allegedly breaching Party. To be an effective notice under this Section 15.3(a), the written notice must (i) explicitly reference this Section 15.3, (ii) describe in reasonable detail the nature of the claimed breach, including the country(ies) in the JDCT or the Royalty-Bearing Territory with respect to which the claimed breach occurred, and (iii) explicitly state that if the breach is not cured, the notifying Party will have the right to terminate this Agreement. For purposes of illustration only and without limitation, a breach of Section 9.6 (Exclusivity Commitment) or a breach of a Party’s diligence obligations under Article 8 shall be deemed a material breach of this Agreement. Promptly following receipt of such notice of breach, the allegedly breaching Party shall discuss in good faith with the other Party (which good faith efforts shall include, if requested by the other Party, at least one in-person meeting between the chief executive officers of each Party, but which does not require either Party to continue discussions for longer than [**] days) the nature of the claimed breach, implications of the circumstances giving rise to the claimed breach, and a proposed plan to cure the claimed breach. Unless otherwise mutually agreed by the Parties, the allegedly breaching Party shall have [**] days (or such longer period of time as may be mutually agreed by the Parties) from the end of the good-faith discussions to cure the breach in accordance with any plan mutually agreed by the Parties failing which the non-breaching Party may terminate this Agreement upon [**] days prior written notice to the other Party; provided that if the breach is not curable, the non-breaching Party may terminate this Agreement upon [**] days’ prior written notice to the other Party; and provided, further, that, unless otherwise mutually agreed by the Parties, the cure period shall be [**] days for breaches involving non-payment of any amount due hereunder.

104

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

(b) Failure to Cure. If, within the applicable cure period set forth in clause (a) above:

(i) the allegedly breaching Party is ASTELLAS, ASTELLAS fails to cure a breach (A) with respect to any Major Market Country, or (B) of Section 9.6 with respect to any country(ies) of the JDCT, and AVEO elects to terminate this Agreement, then this Agreement shall terminate with respect to the JDCT as a whole (with the effects of termination set forth in Section 15.6);

(ii) the allegedly breaching Party is AVEO, AVEO fails to cure the breach with respect to any country(ies) of the JDCT, and ASTELLAS elects to terminate this Agreement, then this Agreement shall terminate solely with respect to such country(ies) of the JDCT (with the effects of termination set forth in Section 15.7); and

(iii) the allegedly breaching Party fails to cure the breach with respect to any country(ies) of the Royalty-Bearing Territory or any countries in the JDCT which are not Major Market Countries (the “Minor Market Countries”) and the Party originally delivering the notice of breach elects to terminate this Agreement, then this Agreement shall terminate solely with respect to such country(ies) of the Royalty-Bearing Territory or such Minor Market Country(ies), as applicable (with the effects of termination set forth in either Section 15.6 if ASTELLAS is the breaching Party or Section 15.7 if AVEO is the breaching Party).

For purposes of clarity, in the event of a partial termination of this Agreement under this Section 15.3 with respect to the JDCT, country(ies) in the JDCT, or country(ies) in the Royalty-Bearing Territory, as the case may be, this Agreement shall continue in full force and effect with respect to the country(ies) of the Licensed Territory unaffected by such partial termination.

(c) Disputes. If a Party gives notice of termination under Section 15.3(a), and the other Party disputes whether such notice was proper, then the issue of whether this Agreement has been terminated shall be resolved in accordance with Article 16 (which Article 16 shall apply and take precedence over any discussions between the Parties under Section 15.3(a)). If as a result of such dispute resolution process it is determined that the notice of termination was proper by reason of a material breach of the Agreement and the breaching Party fails to cure such material breach within the applicable cure period pursuant to Section 15.3(a) after such determination, then such termination of the Agreement (in its entirety, or with respect to the JDCT, country(ies) in the JDCT, or country(ies) in the Royalty-Bearing Territory, as applicable) shall be deemed to be effective as of the date of the notice of termination. If as a result of such dispute resolution process it is determined that the notice of termination was improper, then no termination shall have occurred and this Agreement shall remain in effect (but without affecting any other termination of the Agreement with respect to the JDCT, country(ies) in the JDCT, or country(ies) in the Royalty-Bearing Territory, as applicable, which has either already occurred or was or is otherwise determined to be proper).

15.4 Termination if ASTELLAS Challenges Licensed Patents. If ASTELLAS or any of its Affiliates or Sublicensees (a) initiates or requests an interference or opposition proceeding with respect to any Licensed Patent, (b) makes, files or maintains any claim, demand,

105

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

lawsuit, or cause of action to challenge the validity or enforceability of any Licensed Patent, (c) opposes any extension of, or the grant of a supplementary protection certificate with respect to, any Licensed Patent, or (d) funds or otherwise provides material assistance to any other Person with respect to any of the foregoing, AVEO shall have the right to terminate this Agreement upon thirty (30) days’ prior written notice to ASTELLAS. Any such termination shall only become effective if ASTELLAS or its Affiliate or Sublicensee, as applicable, has not withdrawn such action before the end of the above notice period.

15.5 Effects of Termination by AVEO for ASTELLAS Patent Challenge; Effects of Elective Termination by ASTELLAS.

(c) Transition Assistance. Without limiting the generality of the remainder of this Section 15.5, ASTELLAS shall use its Commercially Reasonable Efforts, at no cost to AVEO, to effect a seamless, timely transition to AVEO of all Development, Manufacturing and Commercialization activities and responsibilities with respect to Licensed Compounds, Licensed Products and Licensed Product Biomarkers for the Section 15.5 Terminated Territory, in accordance with a transition plan to be mutually agreed by the Parties, provided that in no event shall ASTELLAS be required to provide any assistance to AVEO for a period of longer than [**] months following effective termination.

(d) License Grant; Patent and Know-How Assignment. Effective upon such termination, ASTELLAS hereby assigns to AVEO (or AVEO’s designee) any and all ASTELLAS Product IP owned by ASTELLAS directly or through any Affiliate that is necessary to Develop, Manufacture or Commercialize Licensed Compounds, Licensed Products and Licensed Product Biomarkers (including to avoid doubt, ASTELLAS’s interest in all Jointly Owned Product Patents) in the Section 15.5 Terminated Territory. To the extent any ASTELLAS Product IP is not owned by, but is instead licensed to, ASTELLAS, ASTELLAS hereby grants to AVEO (effective upon such termination) an exclusive, irrevocable, perpetual, fully-paid sublicense, with the right to further sublicense, under such ASTELLAS Product IP for the Section 15.5 Terminated Territory, to the extent permitted under ASTELLAS’s agreement with the licensor of such ASTELLAS Product IP, including any Sublicensee or contractor

106

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

hereunder; provided that, to the extent that any licenses or sublicenses to AVEO or KHK, as applicable, have already been obtained from such licensor prior to the effective date of termination, ASTELLAS shall ensure that AVEO and KHK, as applicable, shall retain, at a minimum, such licenses following the effective date of termination.

(e) Trademark License. At AVEO’s election, effective upon such termination, ASTELLAS shall grant to AVEO an exclusive, fully-paid, royalty-free license, with the right to further sublicense, to use Trademarks owned or controlled by ASTELLAS and used solely in connection with the Commercialization of Licensed Compounds, Licensed Products and Licensed Product Biomarkers in the Section 15.5 Terminated Territory.

(h) Final Reconciliation of Pre-Tax Profit or Loss. In the case of a termination by ASTELLAS under Section 15.2(i) or by AVEO under Section 15.4, within [**] days after such termination, the Parties shall conduct a final reconciliation in accordance with Item 3 of Exhibit H for the purpose of calculating Pre-Tax Profit or Loss with respect to the JDCT through the effective date of termination of this Agreement; provided, however, that, API shall remain responsible for fifty percent (50%) of the Development Costs of any clinical trials or other Development activities that (i) are included within the approved JDCT Development Plan in place prior to such termination and (ii) are ongoing, as of the effective date of termination, until the completion or earlier termination of such clinical trials or other Development activities by AVEO.

(ii) if the claimed breach giving rise to termination by ASTELLAS under Section 15.3 relates to any country(ies) in the JDCT (“Transferred Country(ies)”), then:

(A) effective as of the date of ASTELLAS’s waiver of its right to terminate this Agreement hereunder (subject to the Parties’ compliance with any applicable requirements under the Hart-Scott-Rodino Act), such Transferred Country(ies) shall no longer be treated as a country(ies) in the JDCT, but shall instead be treated as a country(ies) in the Royalty-Bearing Territory for purposes of this Agreement, and all Licensed Compounds, Licensed Products and Licensed Product Biomarkers Developed or Commercialized for use or sale in such Transferred Country(ies) shall be deemed Royalty-Bearing Products, including for purposes of the exclusive license grants to API under Section 9.1 and payment of royalties to AVEO under Section 10.7; provided, that, [**], API shall continue to pay [**];

(B) to the extent that AVEO was the Lead Commercialization Party in such Transferred Country(ies), or the Party with lead responsibility with respect to any Development (including regulatory) matters for such Transferred Country(ies), AVEO shall use Commercially Reasonable Efforts to, at its costs and expenses, (1) transition all such Development or Commercialization activities to ASTELLAS in accordance with a transition plan to be mutually agreed by the Parties, to the extent necessary for API to exercise its exclusive license, and to perform its obligations, under this Agreement with respect to Licensed Compounds, Licensed Products and Licensed Product Biomarkers in such Transferred Country(ies), including transfer of Know-How (to the extent that ASTELLAS did not already have access to such Know-How), transfer of INDs, NDAs and Marketing Approvals, transfer of

112

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

relevant clinical data and Safety Data, transfer of Marketing-Related Materials, assignment of Third Party contracts to the extent such assignment is permitted (including clinical trial agreements but excluding Manufacturing agreements, except to the extent mutually agreed by the Parties as part of the transition plan to effect any transfer of Manufacturing Technology to ASTELLAS pursuant to clause (D) below), in each case to the extent Controlled by AVEO, and (2) to provide reasonable technical assistance with respect to any of the foregoing;

(C) AVEO shall be released from its Development and Commercialization obligations, and for cost and expenses related thereto, under this Agreement or the JDCT Commercialization Agreement, as applicable, with respect to Licensed Compounds, Licensed Products and Licensed Product Biomarkers for such Transferred Country(ies), including diligence obligations pursuant to Article 8 (except (1) as set forth in subclause (B) above with respect to transition activities to be performed by AVEO, and (2) for Development Costs in the JDCT Development Plan that are ongoing as of the effective date of termination). ASTELLAS shall assume all such Development and Commercialization obligations with respect to Licensed Compounds, Licensed Products and Licensed Product Biomarkers for such Transferred Country(ies); provided that, as between AVEO and ASTELLAS, AVEO shall retain the sole right and responsibility for interacting with KHK with respect to any matters involving the Transferred Country(ies), or any Licensed Compound, Licensed Product or Licensed Product Biomarker Developed or Commercialized for use or sale in such Transferred Country(ies), to the extent necessary under this Agreement or the KHK Agreement, subject to JSC oversight;

(D) AVEO shall retain all right and responsibility for Manufacturing, and API shall continue to purchase from AVEO all of its (and its Affiliates’) requirements for, Licensed Compounds, Licensed Products and Licensed Product Biomarkers for the Transferred Country(ies), in accordance with Article 4 and the terms of the Clinical Supply Agreement or Commercial Supply Agreement, as applicable; provided that, if the claimed breach giving rise to termination by ASTELLAS under Section 15.3 relates to all countries in the JDCT, (1) AVEO shall transfer to API (or its Affiliate or its designated Third Party manufacturer) all Manufacturing Technology used, as of the effective date of termination, in the Manufacture of Licensed Compounds, Licensed Products and, if applicable, Licensed Product Biomarkers for the JDCT, under a transition plan to be mutually agreed by the Parties, (2) AVEO shall grant to API a non-exclusive, non-transferable (except as set forth in Section 17.7), non-sublicenseable (except to API’s Affiliates and API’s designated Third Party manufacturer) license under such Manufacturing Technology to make or have made such Licensed Compounds, Licensed Products and Licensed Product Biomarkers in the Field for the Transferred Countries for the remainder of the Term, (3) AVEO shall continue to Manufacture and supply to API Licensed Compounds, Licensed Products and, if applicable, Licensed Product Biomarkers for the Transferred Country(ies) in accordance with Article 4 and the terms of the Supply Agreements until such activities have been transitioned to API hereunder and a relevant Regulatory Authority has approved Manufacture by API of such Licensed Compounds, Licensed Products and Licensed Product Biomarkers for the Transferred Country(ies), but in no event for more than [**] years from the effective date of such termination (at which time AVEO’s Manufacturing obligations under the Supply Agreements with respect to the JDCT shall terminate), and (4) API shall pay AVEO for [**] of any supply of Licensed Compounds, Licensed Products and Licensed Product

113

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

Biomarkers provided to API under the foregoing subclause (3) within [**] days of invoice therefor (for clarity, which [**] shall not be shared between the Parties as an Allowable Expense in the calculation of Pre-Tax Profit or Loss);

(E) within [**] days after such waiver, the Parties shall conduct a final reconciliation in accordance with Item 3 of Exhibit H for the purpose of calculating Pre-Tax Profit or Loss through the effective date of termination of this Agreement, to the extent allocable to the Transferred Country(ies); and

(F) all applicable definitions, license grants, financial terms, Development, Commercialization and regulatory provisions, and other relevant terms of this Agreement, the JDCT Commercialization Agreement, the Clinical Supply Agreement, the Commercial Supply Agreement and the SDEA, as applicable, including any related plans, budgets and forecasts, shall be amended by the Parties as necessary to ensure the foregoing.

15.8 Treatment of Sublicensees. In the event of any termination of this Agreement, other than a termination of this Agreement by ASTELLAS under Section 15.2 (Elective Termination), any sublicense granted by API in compliance with this Agreement to a Sublicensee which (a) is then in good standing, and (b) in the case of a termination of this Agreement by AVEO for ASTELLAS’ uncured material breach or patent challenge, has not contributed to the event that led to such termination, shall remain in full force and effect pursuant to the terms thereof, except that such Sublicensee shall become a direct licensee of AVEO and all monies and other obligations due to ASTELLAS thereunder shall become immediately due to AVEO (or its licensor, as may be designated by AVEO) instead of ASTELLAS. The foregoing sentence only applies if the Sublicensee promptly (within [**] days after termination) pays to AVEO any amounts due hereunder that have not by then been paid by ASTELLAS, that are due hereunder in respect of the particular Sublicensee’s sublicensed territory. For the avoidance of doubt, if this Agreement is terminated solely with respect to specific Terminated Territory(ies), this Section 15.8 shall apply to the extent that the Sublicensee’s sublicensed territory is comprised of, or is affected by such termination of, the Terminated Territory(ies).

15.9 Survival.

(a) Upon any termination or expiration of this Agreement, unless otherwise specified in this Agreement, all rights and obligations of each Party under this Agreement shall terminate; provided, however, that the following provisions shall survive any expiration or termination of this Agreement in accordance with their terms: Articles 1, 10 (to the extent any amounts are payable but unpaid as of the effective date of termination), 12, 14, 16 and 17, and Sections 3.6, 4.3, 6.4(b) (the second to last sentence only), 6.4(c)(i) (last sentence only), 11.1, 13.6, 15.1(b), 15.5, 15.6, 15.7, 15.8 and this 15.9.

(b) Expiration or termination of this Agreement, the JDCT Commercialization Agreement, the Clinical Supply Agreement, the Commercial Supply Agreement or the SDEA, as applicable, shall not relieve the Parties of any rights, obligations or liabilities which accrued hereunder or thereunder prior to the effective date of such expiration or termination, nor preclude either Party from pursuing all rights and remedies it may have hereunder or thereunder, or at law

114

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

or in equity, with respect to any breach of this Agreement, the JDCT Commercialization Agreement, the Clinical Supply Agreement, the Commercial Supply Agreement or the SDEA, as applicable, unless otherwise expressly stated herein or therein.

ARTICLE 16

DISPUTE RESOLUTION

16.1 Seeking Consensus. If any dispute, controversy or claim arising out of or relating to the validity, construction, enforceability, performance or breach of this Agreement arises between the Parties (“Dispute”), including any Dispute that is escalated to the JSC by the JDC or JCC pursuant to Section 2.6 or otherwise falls within the jurisdiction of the JSC (e.g., a Dispute concerning matters that are purely business, operational or technical matters) but cannot be resolved by the JSC pursuant to Section 2.6 (“Non-Arbitrable Dispute”), then upon the written request of either Party, the chief executive officers of each Party shall promptly meet and discuss the Dispute and seek to identify and reach agreement on a potential resolution thereof in good faith, which good faith efforts shall include at least one in-person meeting between the chief executive officers of each Party. The written request shall explain the nature of the Dispute and refer to the relevant provisions of the Agreement upon which the Dispute is based. The complaining Party shall also set forth a proposed solution to the problem, including a suggested time frame within which the Parties must act. If the Dispute is not resolved within [**] days following the written request for discussions, either Party may then invoke binding arbitration in accordance with Section 16.2 below to resolve such Dispute, excluding any Non-Arbitrable Dispute (which shall not be subject to further arbitration or litigation hereunder).

16.2 Arbitration.

(a) Notice of Arbitration. Any Dispute which may arise between the Parties that is not resolved pursuant to Section 16.1 shall be settled by binding arbitration as set forth in this Section 16.2, excluding (i) any Non-Arbitrable Dispute, (ii) any Dispute concerning patent term extensions with respect to ASTELLAS Patents and Licensed Patents other than Joint Other Invention Patents (which Dispute shall be resolved pursuant to Section 11.3), and (iii) any Patent and trademark Disputes as specified in Section 16.5 (which shall be resolved pursuant to Section 16.5). Either Party, following the end of the [**] day period referenced in Section 16.1, may refer such issue to arbitration by submitting a written notice of such request to the other Party.

(b) Selection of Arbitrators. The number of arbitrators to resolve any Dispute submitted to arbitration under Section 16.2(a) shall be three (3). Each Party shall select one (1) arbitrator within [**] days following receipt of notice under Section 16.2(a), and the two arbitrators selected by the Parties shall be responsible for selecting the third arbitrator. Each arbitrator shall be neutral and independent of both Parties and all of their respective Affiliates, shall have significant experience and expertise in licensing and partnering agreements in the pharmaceutical and biotechnology industries. If the two arbitrators selected by the Parties cannot agree on a third arbitrator within [**] days following either Party’s request for arbitration hereunder, then such third arbitrator shall be appointed by JAMS, which arbitrator must meet the foregoing criteria.

115

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

(c) Location; Proceedings. The place of arbitration shall be New York City, New York. The proceedings shall be conducted pursuant to the rules set forth by JAMS for international arbitration proceedings. All proceedings and communications shall be in English. Each Party shall have the right to be represented by counsel of its own choosing.

(d) Discovery. The Parties agree that discovery appropriate to the issues in the dispute shall be permitted in the arbitration, including reasonable document requests, pre-hearing exchanges of information, expert witness disclosures, limited depositions of important witnesses and other appropriate discovery, provided that such discovery shall be limited to the narrower of (i) the scope of discovery agreed to by the Parties, or if none can be agreed, established by the arbitrators, and (ii) such discovery as would be permitted by the Federal Rules of Civil Procedure and is approved by the arbitrators, keeping in mind the goal of an expedited and efficient proceeding.

(e) Procedural Rules; Statute of Limitations. The arbitration shall be governed by the procedural and substantive law set forth in Section 16.3 and the United States Arbitration Act, 9 U.S.C. §§1-16 to the exclusion of any inconsistent state laws. The statute of limitations of the State of New York applicable to the commencement of a lawsuit shall apply to the commencement of arbitration under this Article 16; provided that such statute of limitations shall be tolled with respect to the subject matter of any Dispute upon delivery of a Party’s written request under Section 16.1 relating to such Dispute; provided, further, that, if the chief executive officers are unable to resolve such Dispute within the [**] day period specified in Section 16.1, the Parties agree to file the notice of arbitration within [**] days thereafter.

(f) Costs. Each Party shall bear its own costs and expenses and attorneys’ fees in the arbitration, except that the arbitrators may order the non-prevailing Party to bear all or an appropriate part (reflective of the relative success on the issues) of the costs and expenses and reasonable attorneys’ fees incurred by the prevailing Party based on the relative merits of each Party’s positions on the issues in the Dispute. The Party that substantially prevails in the arbitration proceeding shall be paid the arbitrators’ fees and expenses and any administrative fees of arbitration.

(g) Award. Any award rendered by the arbitrators shall be final and binding on the Parties, and shall be governed by the terms and conditions hereof, including the limitation on damages set forth in Section 14.6. Any award to be paid by one Party to the other Party as determined by the arbitrators shall be promptly paid in U.S. dollars free of any tax, deduction or offset; and any costs, fees or taxes incident to enforcing the award shall, to the maximum extent permitted by Applicable Law, be charged against the Party resisting enforcement. Each Party agrees to abide by the award rendered in any arbitration conducted pursuant to this Article 16, and agrees that, subject to the U.S. Federal Arbitration Act, 9 U.S.C. §§ 1-16, judgment may be entered upon the final award in any court of competent jurisdiction, including any court of competent jurisdiction in the United States or in Japan. The award shall include interest from the date of any damages incurred for breach of the Agreement, and from the date of the award until paid in full, at the rate set forth in Section 10.21.

116

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

(h) Confidentiality. All proceedings and decisions of the arbitrator shall be deemed Confidential Information of each of the Parties, and shall be subject to Article 12. Except as required by Applicable Law, neither Party shall make (or instruct the arbitrator to make) any public announcement with respect to the proceedings or decision of the arbitrators without prior written consent of the other Party. The existence of any dispute submitted to arbitration, and the award, shall be kept in confidence by the Parties and the arbitrators, except as required in connection with the enforcement of such award or as otherwise required by Applicable Law.

(i) Survivability. Any duty to arbitrate under this Agreement shall remain in effect and be enforceable after termination of this Agreement for any reason.

16.3 Governing Law. This Agreement shall be governed by and construed under the substantive laws of the State of New York, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

16.4 Injunctive Relief; Remedy for Breach of Exclusivity. Nothing in this Article 16 will preclude either Party from seeking equitable relief or interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding. Specifically, the Parties agree that a material breach by either Party of its obligations in Section 9.6 of this Agreement may cause irreparable harm to the other Party, for which damages may not be an adequate remedy. For the avoidance of doubt, nothing in this Section 16.4 shall otherwise limit a breaching Party’s opportunity to cure a material breach as permitted in accordance with Section 15.3(a).

16.5 Patent and Trademark Disputes. Notwithstanding Section 16.2, any Dispute relating to the scope, validity, enforceability or infringement of any Licensed Patents, ASTELLAS Patents, Jointly Owned Product Patents or Joint Other Invention Patents (for clarity, excluding any Dispute concerning patent term extensions with respect to ASTELLAS Patents and Licensed Patents other than Joint Other Invention Patents, which Dispute shall be resolved pursuant to Section 11.3(b)), or relating to JDCT Trademarks or other Trademarks Controlled by a Party Covering the Manufacture, use, importation, offer for sale or sale of Licensed Products or Licensed Product Biomarkers shall be submitted to a court of competent jurisdiction in the country in which such Patent or trademark rights were granted or arose.

ARTICLE 17

MISCELLANEOUS

17.1 Export Control. This Agreement is made subject to any restrictions concerning the export of products or technical information from the United States of America or other countries which may be imposed upon or related to AVEO or ASTELLAS from time to time. Each Party agrees that it shall not export, directly or indirectly, any technical information acquired from the other Party under this Agreement or any products using such technical

117

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

information to a location or in a manner that at the time of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the appropriate agency or other governmental entity, provided that AVEO shall undertake Commercially Reasonable Efforts to procure all relevant export licenses and other governmental approvals.

17.2 Entire Agreement; Amendment. This Agreement (including the Exhibits hereto), together with the Supply Agreements, the JDCT Commercialization Agreement and the SDEA, set forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties with respect to Licensed Compounds, Licensed Products and Licensed Product Biomarkers, and supersede and terminate all prior agreements and understandings between the Parties with respect to the subject matter hereof, including the Confidentiality Agreement. There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written, between the Parties other than as are set forth herein and therein. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each Party.

17.3 Force Majeure. A Party shall be excused from the performance of its obligations under this Agreement to the extent that such performance is prevented by a Force Majeure and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long as the condition constituting Force Majeure continues and the nonperforming Party takes reasonable efforts to remove the condition. For purposes of this Agreement, “Force Majeure” means conditions beyond a Party’s reasonable control or ability to plan for, including acts of God, war, terrorism, civil commotion, epidemic, failure or default of public utilities or common carriers, and destruction of production facilities or materials by fire, earthquake, storm or like catastrophe; provided, however, that the payment of amounts due and owing hereunder shall not be excused by reason of a Force Majeure affecting the payor. For avoidance of doubt, such payments shall include, without limitation, milestone payments, royalty payments and allocation of Pre-Tax Profit and Loss as described on Exhibit H.

17.4 Notices. Any notice required or permitted to be given under this Agreement shall be in writing, shall specifically refer to this Agreement and shall be deemed to have been sufficiently given for all purposes if mailed by first class certified or registered mail, postage prepaid, express delivery service or personally delivered.

17.7 Assignment. Neither this Agreement nor any right or obligation hereunder may be assigned or otherwise transferred by either Party without the consent of the other Party; provided, however, that either Party may, without such consent, assign this Agreement (a) in whole or in part (whether divided on a geographic basis, in connection with the assignment of the economic benefit of this Agreement, or otherwise), to any of its respective Affiliates; provided that such Party shall remain jointly and severally liable with such Affiliate in respect of all obligations so assigned; such Affiliate has acknowledged and confirmed this in writing effective as of such assignment or other transfer; and such Affiliate shall be bound by this Agreement as if it were a party to it as and to the identical extent applicable to the transferor; or (b) as a whole, if such Party merges with, or all or substantially all of its business or assets are acquired by, another entity (whether by merger, sale of assets, sale of stock or otherwise) (an “M&A Event”), to such Party’s merger partner or the acquirer as part of that M&A Event. Each Party agrees that, notwithstanding any provisions of this Agreement to the contrary, if this Agreement is assigned by such Party in connection with an M&A Event, such assignment shall not provide the non-assigning Party with rights or access to intellectual property or technology of the acquirer of the assigning Party. Any permitted assignment shall be binding on the successors of the assigning Party. Any assignment or attempted assignment by any Party in violation of the terms of this Section 17.7 shall be null and void.

121

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

17.11 Severability. If any provision of this Agreement is held to be invalid or unenforceable in the alternative dispute resolution proceedings specified in Article 16 from which no court appeal can be or is taken, the provision shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof. The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized.

17.14 No Third Party Beneficiaries.

(i) make, effect, initiate, cause or participate in any acquisition of beneficial ownership of any voting securities of AVEO or any voting securities of any subsidiary or other Affiliate of AVEO, if the effect of such acquisition would be to entitle ASTELLAS to cast directly or indirectly more than five percent (5%) of the voting power in any election of directors of AVEO (for purposes of the 5% calculation under this Section 17.16(a)(i), all such securities, rights or options beneficially owned by ASTELLAS (including through Affiliates or others) shall be treated on an as-exercised and as-converted basis, but such securities, rights or options beneficially owned by others shall not be so treated);

122

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

(ii) make, effect, initiate, cause or participate in any acquisition of any material assets of AVEO or any subsidiary of AVEO that would place AVEO or ASTELLAS under a legal obligation to make a public disclosure of such activity;

(v) agree or offer to take, or propose (publicly or otherwise) the taking of, any action referred to in clauses (i), (ii), (iii) or (iv) of this Section 17.16(a);

(vi) assist, induce or encourage any other Person to take any action of the type referred to in clauses (i), (ii), (iii), (iv) or (v) of this Section 17.16(a);

(vii) enter into any discussions, negotiations, arrangement or agreement with any other Person relating to any of the foregoing; or

(viii) request or propose that AVEO or any of AVEO’s representatives amend, waive or consider the amendment or waiver of any provision set forth in this Section 17.16(a).

(b) The obligations and restrictions of ASTELLAS under Section 17.16(a) shall automatically terminate and be of no further force or effect:

(i) upon any Person or group (x) commencing or publicly announcing its intent to commence a tender or exchange offer for securities or other voting interests representing more than [**] percent ([**]%) of the combined voting power of the then outstanding voting securities of AVEO or (y) publicly announcing a bona fide unsolicited proposal to enter into a transaction described in subsection (b)(ii) below;

Should such Third Party(ies) analysis confirm the invalidity of the complaint by ASTELLAS or should the Parties agree that ASTELLAS’s complaint was invalid, then the matter shall be deemed conclusively resolved in AVEO’s favor.

(iv) If the Parties agree, or the Third Party analysis confirms, that ASTELLAS’s complaint was valid, AVEO shall use Commercially Reasonable Efforts to supply to ASTELLAS, as promptly as practicable, (A) Clinical Supply Product conforming to the Clinical Supply Product Warranties, in the remaining quantity necessary to fulfill the applicable Order for such Clinical Supply Product, at no additional expense to ASTELLAS (if the complaint concerned Non-Conforming Supply), or (B) the remaining quantity of Clinical Supply Product necessary to fulfill the applicable Order for such Clinical Supply Product, at the applicable Transfer Price (if the complaint concerned Short Supply).

(e) In the event that AVEO fails to supply at least [**] percent ([**]%) of the Clinical Supply Product ordered by ASTELLAS in the applicable Order in [**] consecutive Firm Forecasts, other than for Force Majeure, then ASTELLAS shall have the option to assume responsibility of the Manufacture and supply of Clinical Supply Product until AVEO demonstrates to ASTELLAS’ reasonable satisfaction that AVEO has fully remedied such supply failure.

Notwithstanding the foregoing, either Party, at its own discretion, may elect to devote additional resources toward the Commercialization of Profit-Share Products in Europe (beyond what is contemplated in the European Commercialization Plan); provided that, all additional costs incurred, beyond [**] percent ([**]%) of what is budgeted in the European Commercialization Plan, shall be borne one hundred percent (100%) by the Party incurring the additional costs, unless otherwise mutually agreed by the Parties.

(b) Travel Expenses. All travel and entertainment expenses related to the performance of activities under the European Commercialization Plan (“Travel Expenses”) shall be subject to a travel and entertainment budget developed by the JECT and approved by the JCC as part of the European Commercialization Plan, and pursuant to a travel policy mutually agreed by the Parties, which in any event shall be at least as restrictive as, and permitting no greater expense rates than, the then-applicable APEL European Corporate Travel and Expense

ARTICLE III

EUROPEAN SALES FORCE; SALES PERFORMANCE; MEDICAL AFFAIRS

ACTIVITIES

3.1 Sales Force Sizing and Alignment.

(a) Sales Force Deployment Plan. APEL shall propose a plan to be incorporated in the European Commercialization Plan for sizing and alignment of APEL’s Sales Force in a manner designed to optimize the profitability of Profit-Share Products in Europe (the “Sales Force Deployment Plan”).

(b) Sizing, Alignment, Performance Objectives. The Sales Force Deployment Plan shall set forth Sales Force sizing, on a country-by-country basis with respect to the Major EU Countries and on a pan-European basis outside the Major EU Countries, and Sales Objectives as provided in Section 3.2. The Sales Force Deployment Plan shall calculate Sales Force sizing based on (i) [**]. Sales territories shall be defined in an unbiased manner based on both objective, quantifiable information and market research and the reasonable discretion and commercial judgment of APEL’s commercial and sales professionals, with the objective of achieving the appropriate reach and Detailing frequency needed to optimize the profitability of Profit-Share Products to achieve applicable Sales Objectives. When formulating amendments to the Sales Force Deployment Plan, APEL shall consult with, and consider in good faith, input received from AVEO UK through the JECT, provided that APEL shall retain the right to reallocate the Sales Force within Europe based on APEL’s reasonable judgment and APEL shall notify the JECT thereof. For the avoidance of doubt, AVEO UK recognizes that APEL may decide from time to time to reassign Sales Force representatives to target customer segments in order to optimize the targeted market opportunity and, as a result, amend the Sales Force Deployment Plan.

(c) Field Management. APEL shall create a field management structure for its sales effort that is consistent with the European Commercialization Plan and its internal management structures. Each sales representative shall have a sales territory that allows such sales representative to perform a reasonable number of Details within a reasonable geographic area (i.e., without overly-burdensome travel requirements), subject to Applicable Law. APEL’s sales representatives shall remain exclusively under the direct authority and control of the field sales management of APEL.

3.2 Sales Objectives.

The European Commercialization Plan shall contain annual performance objectives based on [**] in Europe, on a country-by-country basis with respect to the Major EU Countries and on a pan-European basis outside the Major EU Countries (“Sales Objectives”). Within its Sales Force, APEL shall have discretion to allocate individual goals among sales representatives,

12

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

provided that such individual goals are directed toward meeting the annual Sales Objectives. At the JECT, APEL shall share with AVEO UK quarterly Sales Objectives to the extent available.

3.3 Hiring and Compensation.

(a) Hiring. APEL will be responsible for recruiting, hiring, terminating, establishing and maintaining its Sales Force in accordance with the European Commercialization Plan, its standard procedures, industry standards for oncology products of similar market opportunity and lifecycle stage, and this Article III.

(b) Sales Force Compensation. Only Sales Force compensation included in Includable Sales Force Costs on Exhibit C may be allocated to APEL’s calculation of Commercialization Costs under this Agreement. Sales Force Compensation shall be set in APEL’s sole discretion and the principles governing Sales Force Compensation will be included in the European Commercialization Plan.

(c) Employment Status. None of APEL’s sales representatives or members of its Sales Force shall hold themselves out as, nor give any Person any reason to believe that they are, employees of AVEO UK. Equally, none of AVEO UK’s employees shall hold themselves out as, nor give any Person any reason to believe that they are, employees of APEL. APEL shall be solely responsible for any employee benefits, payroll and employment taxes, insurance and worker’s compensation with respect to its employees, and AVEO UK shall be solely responsible for such matters with respect to its employees, subject (in both cases) to sharing of Commercialization Costs pursuant to the Collaboration Agreement. Each Party shall indemnify the other for all Employment Liabilities (defined in Section 3.3(d) below) arising out of any allegation or claim made against the other Party by any employee of the first Party (excluding Employment Liabilities arising under Section 3.3(d) below, which shall be addressed therein); provided, however, that neither Party shall be obligated to indemnify the other Party (the “indemnitee”) under this Section 3.3(c) to the extent that such Employment Liabilities arise from the breach or alleged breach of this Agreement by the indemnitee, or the negligence or willful misconduct (including any act of discrimination or harassment) of the indemnitee.

(d) Transfer Regulations. If it is found or alleged that the employment of any person(s) employed or engaged by one Party (the “Transferor”) or any of its Affiliates, contractors or agents transfers across to the other Party (the “Transferee”) pursuant to the operation of the Transfer Regulations (as defined below) or otherwise by operation of Applicable Law (each a “Transferring Employee”), the Parties agree that the following terms shall be applicable: (i) the Transferee may terminate the employment of each and every Transferring Employee within [**] calendar days of the later of the date the transfer occurred and the date the Transferee became aware that the Transferring Employee had, or alleged that he had, transferred into the employment of the Transferee and in this event the Transferor shall indemnify and hold harmless the Transferee and all of its Affiliates against all Employment Liabilities (as defined below) that the Transferee and/or any such Affiliates may suffer or incur as a result of, or in connection with, any such termination of employment of each and every Transferring Employee, the employment by the Transferee of each and every Transferring Employee up to the date his employment is terminated in accordance with this article and all employment costs arising from the employment by the Transferee of each Transferring Employee up to the date that the

13

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

termination of employment takes effect; and (ii) the Transferor shall indemnify and hold harmless the Transferee and all of its Affiliates against all Employment Liabilities that the Transferee and/or any such Affiliates may suffer or incur as a result of, or in connection with: (A) the employment of each and every Transferring Employee by the Transferor or any of its Affiliates, contractors or agents prior to or on the date the employment of the Transferring Employee transfers from the Transferor to the Transferee (the “Transfer Date”); and/or (B) any act or omission of the Transferor or any of its Affiliates, contractors or agents (or an act or omission for which the Transferor or any of its Affiliates, contractors or agents is/are vicariously liable) in relation to any Transferring Employee taking place prior to or on the Transfer Date; and/or (C) any failure by the Transferor or any of its Affiliates, contractors or agents to comply with any obligations it has or may have to provide information to, and/or consult with, and/or seek an opinion from, any Transferring Employee(s) or any representatives of any Transferring Employee(s) (including, without limitation, any trade union, staff association, workers’ committee, works council, European works council, appropriate representative or other employee representative) with regard to the transfer of the employment of the Transferring Employees from the Transferor to the Transferee and/or the measures either Party intends to undertake with regard to any Transferring Employee(s).

“Employment Liabilities” means any and all loss, liability (including liabilities arising from any settlements, judgments, orders, fines and penalties), damages, compensation, awards, and/or costs (including reasonable attorneys’ fees, court costs and other litigation expenses) relating to or arising from any actual or threatened claim, action, suit or proceeding (whether civil, criminal, administrative, arbitral, investigative or otherwise) brought under any Applicable Laws directly or indirectly relating to or connected with employees, employment rights, personal injuries or workers compensation in any jurisdiction.

“Transfer Regulations” means any local Applicable Laws implementing the provisions of the Acquired Rights Directive (Council Directive No. 2001/23/EEC of the European Union dated 12 March 2001 as amended or replaced from time to time) and, with regard to any country outside the European Union, any legislation with similar effect to the Acquired Rights Directive.

3.4 Sales Force Maintenance.

(a) Consultation. AVEO UK will keep APEL informed regarding any issues or concerns relating to the conduct of APEL’s sales representatives. The Parties shall discuss in good faith any issues or concerns raised by AVEO UK with respect thereto.

(b) Contract Sales Organizations. It is the intention of APEL to rely primarily on employee sales representatives to meet its obligations hereunder, including under the European Commercialization Plan, and APEL may not employ a CSO to fulfill any of its Commercialization obligations in the JDCT without JCC approval; however, the Parties recognize that at times it may be appropriate for APEL to engage a CSO to cover vacant territories on an interim basis in order to address short-term Sales Force staffing issues and, therefore, AVEO shall not unreasonably withhold its consent (at the JCC) to APEL’s employment of a CSO to address such issues, provided that any CSO shall be required to meet all obligations of APEL under this Article III. All Distributor/CSO Expenses resulting from the employment of an approved CSO shall be included within Commercialization Costs.

14

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

(c) Distributors. For the avoidance of doubt, upon the approval of the JCC, APEL may appoint new or different Distributors in the countries of Europe where APEL has no Affiliates (it being understood that no JCC or JSC approval shall be required with respect to Distributors engaged by APEL or APEL’s European Affiliates as of the Effective Date, a list of which Distributors has been provided to AVEO prior to the Effective Date). All Distributor/CSO Expenses incurred by a Party or an Affiliate of a Party relating to the distribution by a Distributor of Profit Share Products in Europe shall be included within Commercialization Costs.

(d) Competitive Products. APEL’s Sales Force representatives shall not promote another product that is designed to replace, or be a substitute for, the Profit-Share Product for treatment of an approved Indication.

3.5 Performance Monitoring.

APEL will establish, in cooperation with AVEO UK, a transparent and compatible sales performance and sales based objectives monitoring and reporting system consistent with industry custom and practice, and compatible with APEL’s systems, for sales of Profit-Share Products in Europe to facilitate periodic reporting to the JECT and planning and monitoring of the European Commercialization Plan, including Sales Objectives, Details performed, individual Performance to Goals and other sales activities. Details shall be measured by APEL’s internal recording of such activity, provided that such measurement shall be on the same basis as the APEL’s measurement for its sales representatives Detailing of APEL’s other products (if any), consistently applied. Such system shall be reasonably designed to enable AVEO UK to verify the Performance to Goals provided by APEL and the performance of other obligations under the European Commercialization Plan by APEL. APEL agrees to make available to AVEO UK through such system such information as may reasonably be required to accomplish the goals set forth in this Section 3.5.

3.6 MSL Strategy.

The European MSL strategy described in Section 2.2(a)(xiii) shall be included in the European Commercialization Plan and prepared, submitted and approved as part of the preparation, submission and approval of the European Commercialization Plan. Except as otherwise provided in the approved European Commercialization Plan: (1) AVEO UK will be allocated responsibility for fifty percent (50%) of MSL coverage in the Major EU Countries, which MSL coverage shall be AVEO UK’s sole participation in medical affairs efforts related to Profit-Share Products in Europe, (2) the functions to be performed by APEL and AVEO UK MSLs in Europe are described in Exhibit E hereto, (3) AVEO UK shall adopt a policy requiring that, in performing all MSL activities related to Profit-Share Products in Europe, AVEO UK’s MSLs shall follow APEL’s compliance policies and procedures relating to MSL conduct which, for the avoidance of doubt, means that APEL’s policies require that all MSLs shall follow any directions and instructions of the APEL Medical Affairs Director, and (4) APEL shall be solely responsible for medical information, the disbursement of grants and CME administration in Europe. AVEO UK’s MSLs who are engaged to perform MSL activities under this Agreement shall dedicate at least [**] percent ([**]%) of their time and effort to performing MSL activities related to Profit-Share Products in Europe, and the FTE Costs of such AVEO UK MSLs (such

15

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

FTE Costs to be calculated based on percentage of time and effort allocated to Profit Share Products) shall be shared by the Parties under the Collaboration Agreement.

Astellas and AVEO Pharmaceuticals Enter into Worldwide Agreement to Develop and

Commercialize Tivozanib Outside of Asia[**]— AVEO to Receive $125 Million Upfront and

$1.3 Billion in Potential Milestones —

— Global 50/50 Profit Share with AVEO to Lead Commercialization in North America

and Astellas to Lead Commercialization in Europe —

— Agreement Accelerates Development of Tivozanib in Multiple Additional Cancer Indications —

TOKYO, JAPAN and CAMBRIDGE, MASS., February 16, 2011 – Astellas Pharma Inc. (TSE: 4503, “Astellas”), a global pharmaceutical company, and AVEO Pharmaceuticals, Inc. (NASDAQ: AVEO, “AVEO”) today announced that they have entered into a worldwide agreement outside of Asia to develop and commercialize tivozanib, AVEO’s lead product candidate designed to optimally block the VEGF pathway by inhibiting all three VEGF receptors, for the treatment of a broad range of cancers. Tivozanib is currently being investigated in a pivotal, global Phase 3 clinical trial called TIVO-1 comparing the efficacy and safety of tivozanib to sorafenib (Nexavar®) in patients with advanced renal cell carcinoma (RCC), as well as in

J-1

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

additional clinical studies in other solid tumor types as a single agent and in combination with other anti-cancer agents.

Under the terms of the agreement, AVEO will receive an initial cash payment of $125 million, composed of a $75 million license fee and $50 million in research and development funding. AVEO is also eligible to receive approximately $1.3 billion in potential milestones comprised of $575 million in clinical and regulatory milestones, including $90 million in connection with the regulatory filings and market approval of tivozanib in RCC, as well as more than $780 million in commercial milestones. Subject to regulatory approval, AVEO will lead commercialization of tivozanib in North America and Astellas will lead commercialization of tivozanib in the European Union (EU). The companies will share equally all North American and EU development and commercialization costs and profits for tivozanib. Outside of North America and EU, Astellas will be responsible for the development and commercialization costs of tivozanib and will be obligated to pay AVEO a tiered, double-digit royalty on sales in those territories. Pursuant to the terms of a licensing agreement between Kyowa Hakko Kirin and AVEO, Kyowa Hakko Kirin retains the rights to develop and commercialize tivozanib in Asia. AVEO will be responsible for the manufacturing of tivozanib. The upfront cash payment of $125 million is not included in Astellas’ current fiscal year (from April 1, 2010 to March 31, 2011) financial forecast.

“We are very pleased to initiate this collaboration to co-develop and commercialize tivozanib with AVEO as it further supports our stated growth strategy of becoming a Global Category Leader in Oncology,” said Masafumi Nogimori, president and chief executive officer of Astellas. “Oncology is a high-priority therapeutic area for Astellas. We share AVEO’s vision for oncology drug development and confidence that the TIVO-1 trial is positioned for success. We also strongly believe tivozanib has significant potential in multiple cancers beyond RCC and we look forward to working together to maximize the market opportunities for tivozanib and improving the treatment of cancer patients.”

“This collaboration accomplishes the key strategic objectives we were seeking from a partnership for tivozanib which we believe positions us well to realize the full potential value of tivozanib in North America and Europe,” stated Tuan Ha-Ngoc, president and chief executive officer of AVEO. “In particular, the agreement enables us to build out our North American commercial infrastructure to not only launch tivozanib, but also to support future products emerging from our growing oncology pipeline. We are excited to work with Astellas in our efforts to bring tivozanib to market and, based upon our mutual expectation of a favorable outcome in the TIVO-1 trial, we will be moving forward to accelerate and expand the clinical development of tivozanib beyond RCC prior to top-line TIVO-1 data.”

In 2010, AVEO both initiated and completed patient enrollment in TIVO-1, a global, randomized Phase 3 superiority trial evaluating the efficacy and safety of tivozanib compared to sorafenib in patients with clear cell RCC who had a prior nephrectomy. The primary endpoint of the trial is to compare the PFS of patients treated with tivozanib vs. sorafenib. AVEO expects to announce top-line data from TIVO-1 in mid-2011. In addition, tivozanib has demonstrated the ability to be combined with targeted therapies and chemotherapies in multiple indications in Phase 1b clinical trials. In conjunction with the ongoing TIVO-1 trial and combination studies, AVEO and Astellas

will jointly conduct and fund the expansion of tivozanib clinical development into additional solid tumor types.

RCC, or kidney cancer, is the eighth most commonly diagnosed cancer in men and women in the U.S1. Worldwide during 2010, it was estimated that more than 200,000 people would be diagnosed and more than 100,000 people would die from the disease2. RCC, which accounts for 90 percent of all malignant kidney tumors, is highly resistant to chemotherapy3. Despite advances in RCC therapies, significant unmet need persists. Currently available therapies provide patients less than one year of survival without disease progression and are associated with significant toxicities4.

About Tivozanib

Tivozanib, an investigational new drug, is designed to optimally block the VEGF pathway by inhibiting all three VEGF receptors. Each of the three receptors of the VEGF pathway play an important role in angiogenesis (the formation of new blood vessels), which is critical in cancer cell growth. Tivozanib’s high level of potency across VEGF receptors 1, 2 and 3 is designed to potently block the VEGF pathway. Tivozanib’s high level of selectivity for VEGF receptors 1, 2 and 3 is designed to minimize off-target toxicities, and its oral, one capsule, once-daily administration may enhance convenience for patients.

In a large, multi-center, randomized Phase 2 clinical trial, the subset of patients with clear cell renal cell carcinoma (RCC) who had a prior nephrectomy receiving tivozanib therapy achieved 14.8 months progression free survival (PFS), the longest PFS reported for a single-agent therapy in this population5. The safety profile of tivozanib observed in the Phase 2 trial was notable for the minimal off-target toxicities often associated with VEGF, multi-targeted therapies. There was a low incidence of diarrhea, fatigue, stomatitis and hand-foot syndrome. Hypertension and dysphonia (hoarseness of voice), which are mechanism-related side effects associated with angiogenesis inhibitors, were the most commonly reported drug-related side effects, and both were manageable and reversible5. AVEO has completed patient enrollment in TIVO-1, a global, randomized, controlled Phase 3 clinical trial evaluating the efficacy of tivozanib compared to sorafenib (Nexavar®) in this same patient population. The primary endpoint of the trial is to

compare the PFS of patients treated with tivozanib vs. sorafenib. AVEO expects to announce top-line data from TIVO-1 in mid-2011.

Tivozanib has also demonstrated the ability to be combined with both targeted therapies and chemotherapies at the full dose and schedule6-8. In Phase 1b clinical trials to date, tivozanib has demonstrated safety in combination with temsirolimus (Torisel®) in patients with RCC6, FOLFOX6 chemotherapy regimen in patients with colorectal cancer7, and paclitaxel (Taxol®) in patients with metastatic breast cancer8. Tivozanib is also being evaluated in a Phase 1b trial in combination with oral capecitabine (Xeloda®) in patients with metastatic breast and colorectal cancers.
