OPTION GRANT AND DEVELOPMENT DURING OPTION PERIOD

2.1.Grant of Option. AVEO hereby grants to Biogen Idec an exclusive option, exercisable during the Option Exercise Period, as defined in Section 2.2, to acquire from AVEO the licenses set forth in Section 3.1, subject to the terms and conditions of this Agreement (the “Option”).

2.2.Option Exercise Period. AVEO shall deliver the Data Package from the first Proof of Concept Study to Biogen Idec and an initial Development Plan no later than [**] after the last visit of the last patient to be dosed in such Proof of Concept Study. During the [**] following delivery of the Data Package, (i) Biogen Idec may request, and AVEO will provide to Biogen Idec, any other data and information in AVEO’s possession and Control (and AVEO shall make reasonable efforts to procure or produce such other data and information that is not in AVEO’s possession and Control) as Biogen Idec may reasonably request in connection with its review of the Data Package (the “Supplemental Information”), (ii) the Parties shall meet in good faith to discuss Biogen Idec’s comments to the initial Development Plan in accordance with Section 2.9, (iii) AVEO will deliver to Biogen Idec copies of any AVEO In-Licenses entered into after the Effective Date, and (iv) AVEO will deliver to Biogen Idec a reasonably detailed statement of Pre-Option Exercise Phase 3 Manufacturing Costs actually incurred by AVEO and its Affiliates as of such date and reasonably expected to be incurred prior to the end of the Option Exercise Period. The Option shall be exercisable by Biogen Idec at any time during the period commencing on the Effective Date and ending on the later of (i) [**]after delivery of the Data Package, or (ii) [**] after the last to be delivered of the Supplemental Information (the “Option Exercise Period”).

2.3.Option Exercise. In the event Biogen Idec elects to exercise the Option, it shall, no later than the [**] of the [**] of the Option Exercise Period, deliver to AVEO (i) written notice specifying that Biogen Idec has elected to exercise the Option (the “Option Exercise Notice”), and (ii) payment of the Option Exercise Fee. The date, if any, on which Biogen Idec has properly exercised the Option in accordance with the preceding sentence shall be the “Option Exercise Date” for purposes of this Agreement. The Option Exercise Period will be deemed to have ended, and the License Term will be deemed to have commenced, on the Option Exercise Date.

2.4.Effectiveness of License. Upon the exercise by Biogen Idec of the Option in accordance with this Article II, the provisions set forth in Article I and Articles III - XVI of this Agreement shall constitute the terms and conditions of the license and sublicense rights granted by AVEO to Biogen Idec with respect to the AVEO Technology in the Field, and by Biogen Idec to AVEO with respect to Biogen Idec Collaboration Technology, related to all Licensed Products in the Field. During the period commencing on the Effective Date and ending on the expiration of the Option Exercise Period, AVEO will not grant a license or other rights to any Third Party or take any other action that would prevent AVEO from being able to grant to Biogen Idec the license set forth in Section 3.1. In the event Biogen Idec does not exercise the Option during the Option Exercise Period, the licenses and other rights granted under Articles III shall have no force or effect.

2.5.Proof of Concept Development Plan. As promptly as practicable after AVEO has prepared the Proof of Concept Development Plan, AVEO shall provide a copy thereof to Biogen Idec for its review and comment. Biogen Idec shall have a period of [**] to review and comment on the Proof of Concept Development Plan. AVEO shall consider in good faith all reasonable comments made by Biogen Idec to the Proof of Concept Development Plan. If and to the extent requested by Biogen Idec, appropriate members of the clinical development and regulatory teams of AVEO shall meet with appropriate members of the clinical development and regulatory teams of Biogen Idec to discuss the Proof of Concept Study, including the design thereof as well as the Licensed Product and indication being studied in the Proof of Concept Study, and the Development activities and timelines contemplated under the Proof of Concept Development Plan. AVEO may amend, modify, supplement or update the Proof of Concept Development Plan at any time and from time to time in its discretion, provided that AVEO complies with the foregoing provisions of this Section 2.5 (but with Biogen Idec having a [**] review period instead of [**]) with respect to any such amendment, modification, supplement or update of the Proof of Concept Development Plan to the same extent as AVEO is required in connection with the initial Proof of Concept Development Plan, and any such amendment, modification, supplement or update of the Proof of Concept Development Plan is consistent with the parameters set forth in the next sentence. The Proof of Concept Development Plan proposed by AVEO hereunder, including any amendment, modification, supplement or update, shall meet the following parameters: [**].

2.6.Development During Option Period. During the Option Exercise Period, AVEO shall have sole responsibility for Development and Manufacture of Licensed Product, at AVEO’s sole cost and expense, and AVEO shall use Commercially Reasonable Efforts to perform its Development activities as contemplated under the Proof of Concept Development Plan and to Develop Licensed Product through completion of the first Proof of Concept Study. For purposes of clarity, Biogen Idec shall have no right to Develop or Manufacture Licensed Product during the Option Exercise Period. During the Option Exercise Period, AVEO shall not enter into any AVEO In-License with respect to any Know-how or Patent Rights as to which (x) rights thereto in both the AVEO Territory and Licensed Territory will be necessary, (y) such Know-how is incorporated in any Licensed Product or such Patent Rights Cover any Licensed Product or (z) such Know-how or Patent Rights are owned or licensed by a Sublicensee (or any of such Sublicensee’s Affiliates) to whom AVEO has granted a license or sublicense under AVEO Technology or Biogen Idec Collaboration Technology to Commercialize Licensed Product in the AVEO Territory, unless either (i) such AVEO In-License includes rights with respect to such

Know-how and Patent Rights in both the AVEO Territory and the Licensed Territory and such rights are Controlled by AVEO during the Agreement Term or (ii) to the extent Control cannot be obtained, licenses are available, as a matter of course, separately from the licensor of such Know-how or Patent Rights for Development, Manufacture or Commercialization, as the case may be, of Licensed Product in both the AVEO Territory and the Licensed Territory on terms that, at the time AVEO enters into such license, would be substantially the same as the terms obtained by AVEO with respect to the AVEO Territory, and AVEO provides written notice to Biogen Idec that Control could not be obtained. For purposes of clarification and not by way limitation, it is understood and agreed that the term “necessary” as used in this Section 2.6 shall be deemed to include any Know-how or Patent Rights as to which rights in both the AVEO Territory and Licensed Territory would be necessary for Biogen Idec to Develop, Manufacture or Commercialize, as the case may be, Licensed Product in both the AVEO Territory and the Licensed Territory under this Agreement, including, without limitation, under Sections 5.11, 5.12, 7.5, 13.1, 13.3 or 14.5(b).

2.7.Decision-making during Option Period. During the Option Exercise Period, AVEO shall have sole decision-making authority with respect to Development and Manufacture of Licensed Product, provided that AVEO complies with the provisions of Section 2.5 hereof.

2.8.Development Updates. On a quarterly basis during the Option Exercise Period, AVEO and Biogen Idec will hold an in-person meeting, at either AVEO’s or Biogen Idec’s headquarters in Massachusetts, at such time as the Parties shall mutually agree, during which AVEO shall present the results of its Development activities related to Licensed Product since the last update, and shall describe its Development plans with respect to Licensed Product for the following three months and the remainder of the then Calendar Year.

2.9.Initial Development Plan. As soon as AVEO has prepared the initial Development Plan (even if prior to delivery of the Data Package), AVEO shall deliver to Biogen Idec the initial Development Plan. During the period between Data Package delivery by AVEO and Option Exercise Date, AVEO and Biogen Idec, including appropriate members of the clinical development and regulatory teams of both AVEO and Biogen Idec shall meet to discuss the initial Development Plan, including the design thereof as well as the indication being studied, and the Development activities and timelines contemplated thereunder. In anticipation of Biogen Idec’s exercise of the Option, AVEO shall (x) consider in good faith all reasonable Biogen Idec proposals to such initial Development Plan and (y) deliver to Biogen Idec a revised initial Development Plan (or if no revised initial Development Plan is delivered, the initial Development Plan shall be deemed re-delivered) no less than thirty (30) days prior to the end of the Option Exercise Period (the “Delivered Initial Development Plan”). The Delivered Initial Development Plan shall meet the following criteria: (i) such Delivered Initial Development Plan shall be directed only to the indication that was the subject of the Proof of Concept Study; (ii) the size of the pivotal trial included in such Delivered Initial Development Plan shall be reasonable given the scope of the indication, in light of then prevailing industry standards and regulatory guidance; (iii) such Delivered Initial Development Plan shall in addition include, at a minimum, study designs, assignment of responsibilities (both among the Parties and Third Parties), timelines, decision criteria, supply plans, quality standards, expected resources, costs and a budget for Development Costs; and (iv) the budget for Development Costs in such Delivered

Initial Development Plan shall be for no longer than through the end of completion of the pivotal trial for the indication that was the subject of the Proof of Concept Study.

The Parties agree that it may be necessary or desirable at any time and from time to time during the License Term to enter into agreements with a Third Party to acquire, in-license or otherwise obtain or use technology, intellectual property rights, information, materials, data or know-how, patentable or otherwise, owned or Controlled by such Third Party (“Third Party Technology”) in order for either Party to Develop, Manufacture or Commercialize Licensed Product under this Agreement (such Third Party agreements being hereinafter referred to, collectively, as the “Third Party Technology Agreements”). Such Third Party Technology Agreements shall not conflict with the terms and conditions of this Agreement. In the event that either Party believes that entering into a Third Party Technology Agreement is necessary or desirable in connection with the Development, Manufacture or Commercialization of Licensed Product pursuant to this Agreement, such Party shall notify the JDC and the other Party promptly and include in such notification a summary of the Third Party Technology that would be covered by such Third Party Technology Agreement, the anticipated commercial terms of such Third Party Technology Agreement and any other relevant information. The JDC shall discuss (i) whether the Third Party Technology that would be the subject of such Third Party Technology Agreement is necessary or desirable in connection with the Development, Manufacture or Commercialization of Licensed Product pursuant to this Agreement, (ii) the anticipated commercial terms of such Third Party Technology Agreement, (iii) the advantages and disadvantages associated with entering into such Third Party Technology Agreement at that time or at a later point in time and (iv) any other factors the JDC deems relevant. If the JDC determines that such Third Party Technology Agreement should be pursued, AVEO shall be responsible for negotiating, in consultation with the JDC and Biogen Idec, any such Third Party Technology Agreements and, upon final approval of the JDC as provided below, for entering into such Third Party Technology Agreements. AVEO shall use Commercially Reasonable Efforts to negotiate as promptly as possible such Third Party Technology Agreements that the JDC has determined to pursue and throughout such negotiation AVEO shall consider in good faith and use Commercially Reasonable Efforts to get the applicable Third Party to agree to all reasonable comments made by the JDC and Biogen Idec with respect to such Third Party Technology Agreements and the terms thereof. Prior to execution of any such Third Party Technology Agreement, AVEO shall present the agreement in substantially final form to the JDC for review and final approval. Unless Biogen Idec otherwise agrees, the JDC shall not provide final approval to any such Third Party Technology Agreement unless (A) the Third Party Technology that is subject to such Third Party Technology Agreement may be used by, sublicensed to, or the benefits made available to, Biogen Idec and its Affiliates and Sublicensees

in connection with the Development, Manufacture and Commercialization of Licensed Product pursuant to, and in accordance with, the terms of this Agreement, and (B) in the event that such Third Party Technology may not be used by and sublicensed to Biogen Idec and its Affiliates and Sublicensees in connection with the Development, Manufacture and Commercialization of Licensed Product under this Agreement, then such Third Party Technology is available for licensing, as a matter of course, separately from the licensor of such Third Party Technology with respect of both the AVEO Territory and the Licensed Territory on terms that, at the time of final JDC approval, would be substantially the same as the terms obtained by AVEO with respect to the AVEO Territory. Upon final review and approval by the JDC of any Third Party Technology Agreement in accordance with this Section 3.6, AVEO shall execute and deliver such Third Party Technology Agreement and such Third Party Technology Agreement shall be an AVEO In-License for purposes of this Agreement. AVEO shall provide Biogen Idec with an unredacted copy of such fully executed Third Party Technology Agreement. Notwithstanding anything in this Agreement to the contrary, in the event the JDC unanimously agrees that Biogen Idec shall enter into a Third Party Technology Agreement in accordance with the process outlined in this Section 3.6, then Biogen Idec shall execute and deliver such Third Party Technology Agreement and provide an unredacted copy of such fully executed Third Party Technology Agreement to AVEO which such Third Party Technology Agreement shall be a Biogen Idec In-License. The Know-how and Patent Rights underlying a Biogen Idec In-License shall be deemed to be Biogen Idec Collaboration Technology. As promptly as practicable after the execution of such Third Party Technology Agreement (unless already done prior to the execution of such Third Party Technology Agreement), the Development Plan shall be amended to include actions required related to any such Third Party Technology Agreement and the Third Party Technology that is subject thereto. Except as set forth in Section 3.6(b) below, unless and until the JDC provides final approval of a Third Party Technology Agreement as contemplated above in this Section 3.6(a), neither Party shall enter into such Third Party Technology Agreement. For the sake of clarity, the terms of this Section 3.6 shall not apply to AVEO In-licenses entered into prior to the Option Exercise Date.

(b)Failure to Agree. In the event that the JDC determines that a Third Party Technology Agreement should not be pursued or the representatives of either Party on the JDC will not agree, or do not agree in a timely manner, to the terms that the other Party or the representatives of the other Party on the JDC proposes or propose to accept, and no further discussions are authorized by the JDC or are ongoing by the JDC, either Party alone shall have the right to enter into an agreement with such Third Party on such terms as such Party and the Third Party shall agree in connection with rights to Develop, Manufacture and/or Commercialize a Licensed Product in each Party’s respective territory. In addition, in the event that AVEO is required to negotiate and enter into any Third Party Technology Agreement pursuant to this Section 3.6 but AVEO does not do so, or is unable to do so, in a timely manner, then Biogen Idec shall have the right (but not the obligation) to negotiate and enter into such Third Party Technology Agreement. In the event AVEO enters into a Third Party Technology Agreement under this Section 3.6(b), (i) such agreement shall not be considered an AVEO In-License, (ii) the underlying Patent Rights shall not be considered AVEO Patent Rights or AVEO Collaboration Patent Rights, and (iii) the underlying Know-how shall not be considered AVEO Know-how or AVEO Collaboration Know-how. In the event Biogen Idec or any of its Affiliates enters into a Third Party Technology Agreement under this Section 3.6(b), (i) such agreement shall not be considered a Biogen Idec In-License, (ii) the underlying Patent Rights shall not be

considered Biogen Idec Collaboration Patent Rights, and (iii) the underlying Know-how shall not be considered Biogen Idec Collaboration Know-how. Notwithstanding anything express or implied in the foregoing provisions of this Section 3.6(b) to the contrary, (A) AVEO agrees that it and its Affiliates will not assert any rights acquired under any Third Party Technology Agreement entered into by AVEO under the terms of this Section 3.6(b) against Biogen Idec or any of its Affiliates or Sublicensees with respect to the Development, Manufacture or Commercialization of Licensed Product by Biogen Idec or any of its Affiliates or Sublicensees pursuant to, and in accordance with, the terms of this Agreement, and (B) Biogen Idec agrees that it and its Affiliates will not assert any rights acquired under any Third Party Technology Agreement entered into by Biogen Idec under the terms of this Section 3.6(b) against AVEO or any of its Affiliates or Sublicensees with respect to the Development, Manufacture or Commercialization of Licensed Product by AVEO or any of its Affiliates or Sublicensees pursuant to, and in accordance with, the terms of this Agreement; provided, however, that nothing in this sentence shall prevent or restrict, or be deemed a representation with respect to, the ability of a Third Party licensor to fully assert its rights against a Party, and notwithstanding anything express or implied in the foregoing provisions of this sentence to the contrary, the provisions of clause (A) of this sentence shall not apply with respect to any Licensed Product if Biogen Idec is not required to pay royalties to AVEO pursuant to Section 8.5 hereof on Net Sales by Biogen Idec and its Affiliates and Sublicensees of such Licensed Product in the Licensed Territory, and the provisions of clause (B) of this sentence shall not apply with respect to any Licensed Product if the license rights granted by AVEO to Biogen Idec and its Affiliates pursuant to, and in accordance with, Section 3.1 hereof are not applicable to such Licensed Product for any reason or if AVEO is not required to pay royalties to Biogen Idec pursuant to Section 8.6 hereof on Net Sales by AVEO and its Affiliates and Sublicensees of such Licensed Product in the AVEO Territory. Each Party that enters into a Third Party Technology Agreement that is not considered an AVEO In-License or a Biogen Idec In-License, as the case may be, by virtue of the foregoing provisions of this Section 3.6(b) shall, at the request of the other Party made at any time during the License Term, agree to include any rights under such Third Party Technology Agreement that such Party Controls in the licenses granted to the other Party under Article III, as AVEO Technology or Biogen Idec Collaboration Technology, as the case may be, provided that the other Party makes payment to such Party of all amounts that the other Party would have been required to pay under this Agreement in connection with such Third Party Technology Agreement if such Third Party Technology Agreement had been considered an AVEO In-License or a Biogen Idec In-License, as the case may be, under this Agreement from and after the date that such Party entered into such Third Party Technology Agreement, in which case such Third Party Technology Agreement shall be considered an AVEO In-License or a Biogen Idec In-License, as the case may be.

3.7.Right of First Negotiation. In the event that AVEO proposes to license or sublicense or otherwise grant to a Third Party all or any portion of the rights of AVEO to Commercialize Licensed Product in a particular country of the AVEO Territory, other than solely for purposes of a relationship of the type described in Section 3.3(e), regardless of whether AVEO or a Third Party makes the initial proposal, then AVEO will promptly notify Biogen Idec in writing thereof. As soon as practicable, Biogen Idec will respond to AVEO in writing regarding its interest in entering into negotiations to obtain such rights and the Parties will promptly commence exclusive, good faith negotiations through and until the [**] following the date that AVEO gives such written notice to Biogen Idec. Upon commencement of such

negotiations, AVEO shall advise Biogen Idec of the factors that AVEO considers to be commercially material to its decision to grant Commercialization rights with respect to Licensed Product in such country of the AVEO Territory. If AVEO and Biogen Idec are unable to agree on material terms within [**] after receipt by Biogen Idec of AVEO’s notice of its intent to transfer Commercialization rights, AVEO shall thereafter be free to negotiate and /or enter into an agreement with any Third Party on such terms as AVEO may decide in its sole discretion

3.8.No Inconsistent Third Party Agreements; Amendments. During the Agreement Term, neither Party nor any of its Affiliates shall enter into any in-license of Third Party intellectual property pursuant to which such Party or any of its Affiliates grants to such Third Party rights under or to AVEO Technology or Biogen Idec Collaboration Technology, as the case may be, that would contravene or be inconsistent or in conflict with the rights of the other Party under this Agreement. During the Agreement Term, neither Party nor any of its Affiliates shall amend, modify or terminate any in-license of Third Party intellectual property (including, without limitation, any such in-license that is in effect as of the Effective Date) without the prior written consent of the other Party (which may be granted or withheld by such other Party in its absolute discretion) if such amendment, modification or termination would materially adversely affect any of the rights that such other Party or any of its Affiliates would have under this Agreement if such amendment, modification or termination were not effected.

3.9.M&A Events. In the event of an M&A Event, as defined below, to which AVEO is a party, (i) the Patent Rights owned or otherwise Controlled by the Third Party acquiror or any of its Affiliates immediately prior to the effectiveness of the M&A Event will be specifically excluded from the definition of AVEO Patent Rights and AVEO Collaboration Patent Rights, (ii) the Know-how owned or otherwise Controlled by the Third Party acquiror or any of its Affiliates prior to the effective date of the M&A Event will be specifically excluded from the definition of AVEO Know-how, (iii) in no event shall any agreement that such Third Party acquiror or any of its Affiliates is a party prior to the effective date of the M&A Event be considered an AVEO In-License, (iv) any product owned or otherwise Controlled by the Third Party acquiror or any of its Affiliates immediately prior to the effectiveness of the M&A Event shall be specifically excluded from the definition of Licensed Product, and (v) the restrictive covenants set forth in Section 3.4 shall not apply to any ERBB3 Antibody that is not a Licensed Product by reason of the foregoing clause (iv) (it being understood and agreed that the provisions of this clause (v) shall not limit Biogen Idec’s rights under Section 13.1 or Section 14.5(e)). In the event of any M&A Event to which Biogen Idec is a party, the Patent Rights owned or Controlled by the Third Party acquiror or any of its Affiliates immediately prior to the effectiveness of the M&A Event and the Patent Rights covering Know-how developed or acquired after the effective date of the M&A Event (other than Biogen Idec Collaboration Patent Rights) and any ERBB3 Antibody that is not a Licensed Product by reason of the foregoing clause (iv) shall not be subject to the covenant not to xxx granted to AVEO under Section 3.2(b) or Section 3.6(b). For purposes of this Agreement, an M&A Event with respect to a Party shall mean any of the following: (a) the sale or disposition of all or substantially all of the assets of such Party or its direct or indirect parent corporation to a Third Party, (b) the acquisition by a Third Party which constitutes one person, as such term is used in Section 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), together with any such person’s “affiliates” or “associates”, as such terms are defined in the Exchange Act, other than an employee benefit plan (or related trust) sponsored or maintained by such Party or any of its Affiliates, of more than 50% of the

outstanding shares of voting capital stock of such Party or its direct or indirect parent corporation, or (c) the merger or consolidation of such Party or its direct or indirect parent corporation with or into another corporation, other than, in the case of this clause (c), an acquisition or a merger or consolidation of a Party or its direct or indirect parent corporation in which holders of shares of the voting capital stock of the Party or its direct or indirect parent corporation, as the case may be, immediately prior to the acquisition, merger or consolidation will have at least fifty percent (50%) of the ownership of voting capital stock of the acquiring Third Party or the surviving corporation in such merger or consolidation, as the case may be, immediately after the merger or consolidation.

ARTICLE IV.
GOVERNANCE DURING LICENSE TERM

4.1.Joint Development Committee Formation. As soon as reasonably practicable after the Option Exercise Date, and in any event not later than thirty (30) days after the Option Exercise Date, the Parties shall establish a joint development committee (the “JDC”). The JDC shall consist of three (3) representatives designated by each Party, or such other number as the Parties may from time to time mutually agree. Each Party shall appoint its initial representatives on the JDC at the time of formation, but may, from time to time, substitute one or more of its representatives, in its sole discretion, effective upon notice to the other Party of such change. Each Party shall have at least one JDC representative who is a senior employee (vice president level or above) and shall designate him/her upon designation to the JDC as its senior representative (such representative, such Party’s “Senior Representative”). All JDC representatives shall have appropriate expertise and ongoing familiarity with Development of biopharmaceutical products. Additional representatives or consultants may from time to time, by mutual consent of the Parties, be invited to attend JDC meetings, provided that such representatives and consultants are subject to written obligations that are no less stringent than the confidentiality obligations and restrictions on use set forth in Article X. Each Party shall bear its own expenses relating to attendance at JDC meetings by its representatives.

4.2.Chairperson. The chairperson of the JDC (the “JDC Chairperson”) shall be a representative of AVEO. The JDC Chairperson’s responsibilities shall include (i) scheduling meetings as described in Section 4.3, or more frequently if the JDC determines it necessary; (ii) setting agendas for meetings with solicited input from other members; and (iii) confirming and delivering minutes to the JDC for review and final approval.

4.3.Meetings. The first JDC meeting shall be held within sixty (60) days after the Option Exercise Date, and the JDC shall meet in accordance with a schedule established by mutual agreement of the Parties, but, unless the Parties otherwise agree, the JDC shall meet no less frequently than once each Calendar Quarter, with the location for such meetings alternating between AVEO and Biogen Idec facilities in Massachusetts (or such other locations as determined by the JDC). Alternatively, the JDC may meet by means of teleconference, videoconference or other similar communications equipment, but at least one (1) meeting per Calendar Year shall be conducted in person.

4.4.JDC Responsibilities. The JDC shall have the following responsibilities with respect to the Development of Licensed Product during the License Term:

(i)reviewing and approving (A) the Development Plan, (B) each annual update to the Development Plan, (C) any other modifications to the Development Plan, in each case within thirty (30) days after each submission thereof to the JDC (or sooner as circumstances warrant), and (D) guidelines for conduct of Territory-Specific Clinical Trials and Post-Approval Clinical Studies;

(ii)monitoring and overseeing Development of Licensed Product in the Field in the Territory, and monitoring the Parties’ respective commitments relating to shared Development Costs;

(iii)reviewing updates from AVEO regarding the Development of the Licensed Product in the Territory, and updates from Biogen Idec regarding the conduct of Territory-Specific Clinical Trials and Post Approval Clinical Studies, including, in each case a review of (a) the status of such Development efforts; (b) the results of pre-clinical and clinical studies of Licensed Product in the Field completed since the last update; (c) the design of proposed pre-clinical and clinical studies, and (d) the content of proposed regulatory filings related to Licensed Product in the Field in the Territory;

(iv)regularly assessing the progress of conduct of the Development Plan against the timelines and budgets contained therein, and reviewing relevant data, and considering issues of priority; and

(v)coordinate on issues related to Manufacture of Licensed Product for the Field in the Territory, subject to Article VII.

For purposes of clarity, it is expected that with respect to the sharing of information regarding the Licensed Product, each Party will, through the JDC and through regular communication between each Party’s designated Collaboration Manager, keep the other Party informed at a detailed level about all activities related to the Development and Manufacture of the Licensed Product in the Field under this Agreement, and will provide all information requested by the other Party related to the Development and Manufacture of the Licensed Product in the Field.

The JDC shall not have the authority to modify the terms of this Agreement.

4.5.Appointment of Subcommittees, Project Teams and Collaboration Managers. The JDC shall be empowered to create such subcommittees of itself and project teams as it may deem appropriate or necessary. Each such subcommittee and project team shall report to the JDC, which shall have authority to approve or reject recommendations or actions proposed thereby subject to the terms of this Agreement. Each Party shall also designate a collaboration manager (each a “Collaboration Manager”), who shall be responsible for day-to-day coordination between the Parties and will serve to facilitate communication between the Parties with respect to Development, Manufacture and Commercialization of Licensed Product under this Agreement. Each Party may change its designated Collaboration Manager from time to time upon written notice to the other Party.

4.6.Meeting Materials and Minutes.

(a)Meeting Materials. Each Party will provide the members of the JDC with copies, which may be in electronic format, of all materials it intends to present at a JDC meeting. The JDC may also request at any time specific data or information related to Development activities or any other data to which the JDC is entitled under this Agreement or that a written report be prepared in advance of any meeting summarizing certain material data and information arising out of the conduct of the Development of Licensed Product or any other data to which the JDC is entitled under this Agreement and the Party or appropriate committee to whom such request is made shall promptly provide to the other Party or the JDC such report, data or information.

(b)Minutes. A secretary shall be appointed for each meeting and shall prepare minutes of the meeting, which such minutes shall be subject to approval by the JDC.

4.7.Decisions.

(a)Day-to-Day Management. The Parties agree that (i) decisions with respect to the day-to-day management of Development of Licensed Product in the Field in the Territory (other than the conduct of Territory-Specific Clinical Trials and Post-Approval Clinical Studies in the Licensed Territory) shall not be within the purview of the JDC, but instead shall be the sole responsibility of AVEO, and (ii) decisions with respect to the day-to-day management of Territory-Specific Clinical Trials and Post-Approval Clinical Studies in the Licensed Territory shall not be within the purview of the JDC, but instead shall be the sole responsibility of Biogen Idec, in each case provided such decisions are consistent with the Development Plan, and, subject, in each case to the restrictions contained in Section 4.8(a) and 4.8(b).

(b)JDC Decisions. During the License Term, decisions within the purview of the JDC shall be made by the JDC by consensus, with the representatives of each Party collectively having one vote on behalf of such Party. For each meeting of the JDC, at least two (2) representatives of each Party shall constitute a quorum. Action on any matter may be taken at a meeting, by teleconference, videoconference or by written agreement.

4.8.Deadlocks. The JDC shall attempt to resolve any and all disputes relating to Development of Licensed Product during the License Term by consensus. If the JDC is unable to reach a consensus with respect to a dispute within its purview related to Development of Licensed Product then the dispute shall be submitted to the Senior Representatives for review. If the Senior Representatives cannot reach an agreement regarding such dispute within thirty (30) days after submission to them for resolution, then, if the dispute is one over which the JDC has authority pursuant to this Agreement: (i) Biogen Idec shall have final-decision-making authority with respect to decisions related to Territory-Specific Clinical Trials and Post-Approval Clinical Trials required or reasonably useful in connection with Regulatory Approval or Commercialization of Licensed Product in the Licensed Territory, and (ii) AVEO shall have the final decision-making authority with respect to all other decisions related to Development, subject in each case to paragraphs (a) and (b) of this Section 4.8. Notwithstanding anything in this Agreement to the contrary, any decision within the purview of the JDC for which one of the

Parties has exercised its final decision-making authority, as set forth in this Agreement, shall be considered a decision or approval of the JDC.

(a)Limitations on Decision-Making Authority. Neither Party may exercise its final decision-making authority during the License Term: (i) to require the other Party to perform any Development activities for which it is not responsible under this Agreement or, subject to Section 5.2, to amend the Development Plan in such a way that it no longer meets the Development Plan Guidelines set forth in Exhibit B (the “Development Plan Guidelines”); (ii) to resolve any dispute as to what level of effort constitutes Commercially Reasonable Efforts; (iii) to decide to conduct, sponsor, fund or otherwise support a clinical study, including a Territory-Specific Clinical Trial or a Post-Approval Clinical Study that would materially and adversely affect the Development or Commercialization of the Licensed Product in the other Party’s Territory; (iv) to decide to pursue or not to pursue the negotiation and execution of a Third Party Technology Agreement subject to, and in accordance with, Section 3.6 hereof; (v) to require a Party to take any action that would, or fail to take any action where the failure to take such action would, violate any applicable Law, rule or regulation or infringe the intellectual property rights of Third Parties; (vi) to expand or narrow the responsibilities of the JDC; (vii) to increase or change the budget for Development Costs; (viii) to establish guidelines for the conduct by Biogen Idec of any of the Development activities contemplated under Section 5.1(b) hereof or (ix) to amend this Agreement. For the avoidance of doubt, subject to Section 5.2, any decision by the JDC with respect to any of the items referred to in the foregoing clauses (i)-(viii) of this Section 4.8(a) must be unanimous and, in the event of any disagreement or deadlock at the JDC with respect to any of such items, neither Party may exercise its final decision-making authority with respect to such matter during the License Term.

(b)Other Disputes. With respect to all disputes between the Parties during the License Term related to Development or Manufacture of Licensed Product under this Agreement that are not subject to either Party’s final decision-making authority as set forth in Section 4.7 or this Section 4.8, the dispute resolution provisions of Article XV shall apply.

(“Competitive Infringement”) in the Territory, and shall provide the other Party with all available evidence supporting such infringement, or unauthorized use or misappropriation.

(b)Rights to Enforce.

(i)AVEO’s First Right. Subject to the provisions of any Third Party agreement under which AVEO’s rights in AVEO Technology are granted and subject to paragraph (ii), AVEO shall have the sole and exclusive right to initiate an infringement or other appropriate suit anywhere in the world against any Third Party who at any time has infringed, or is suspected of infringing, any Patent Rights, or of using without proper authorization any Know-how comprising AVEO Technology or Joint Collaboration IP for which AVEO has prosecution responsibility under Section 9.3.

(ii)Biogen Idec’s First Right. Subject to the provisions of any Third Party agreement under which Biogen Idec’s rights in Biogen Idec Collaboration Technology are granted, Biogen Idec shall have the sole and exclusive right to initiate an infringement or other appropriate suit anywhere in the world against any Third Party who at any time has infringed, or is suspected of infringing, any Patent Rights, or of using without proper authorization any Know-how, comprising Biogen Idec Collaboration Technology or Joint Collaboration IP for which Biogen Idec has prosecution responsibility under Section 9.3.

(iii)Requests to Initiate Enforcement Action. AVEO will consider in good faith any request from Biogen Idec to initiate an infringement or other appropriate suit in the Licensed Territory against any Third Party with respect to a Competitive Infringement of AVEO Technology or Joint Collaboration I.P. for which AVEO has prosecution responsibilities under Section 9.3; provided, however, that AVEO shall not be required to initiate any such suit. If, however, AVEO elects not to initiate such suit, or otherwise does not commence suit within one-hundred eighty (180) days of Biogen Idec’s request made under the preceding sentence, Biogen Idec shall have the right to initiate such suit and to join AVEO as a party. Biogen Idec will consider in good faith any request from AVEO to initiate an infringement or other appropriate suit against any Third Party with respect to a Competitive Infringement in the AVEO Territory of a Biogen Idec Collaboration Patent Right or any Joint Collaboration I.P. for which Biogen Idec has prosecution responsibilities under Section 9.3; provided, however, that Biogen Idec shall not be required to initiate any such suit. If, however, Biogen Idec elects not to initiate such suit, or otherwise does not commence suit within one-hundred eighty (180) days of AVEO’s request made under the preceding sentence, AVEO shall have the right to initiate such suit and to join Biogen Idec as a party. For the sake of clarity, in no event shall Biogen Idec have the right to enforce in the AVEO Territory any AVEO Patent Rights, AVEO Collaboration Patent Rights or Joint Collaboration IP for which Biogen Idec has prosecution responsibilities under Section 9.3, and in no event shall AVEO have the right to enforce in the Licensed Territory Biogen Idec Collaboration Patent Rights or Joint Collaboration IP for which AVEO has prosecution responsibilities under Section 9.3.

(c)Procedures; Expenses and Recoveries. The Party having the right to initiate any infringement suit under Section 9.6(b) above shall have the sole and exclusive right to select counsel for any such suit and shall pay all expenses of the suit, including attorneys’ fees and court costs and reimbursement of the other Party’s reasonable out-of-pocket expense in rendering assistance requested by the initiating Party; provided that with respect to any such suit, the Parties may mutually agree to jointly bear such costs and expenses, in which case the allocation of recoveries described below may be adjusted as mutually agreed by the Parties. If required under applicable law in order for the initiating Party to initiate or maintain such suit, or if either Party is unable to initiate or prosecute such suit solely in its own name or it is otherwise advisable to obtain an effective legal remedy, in each case, the other Party shall join as a party to the suit and will execute and cause its Affiliates to execute all documents necessary for the initiating Party to initiate litigation to prosecute and maintain such action. In addition, at the initiating Party’s request, the other Party shall provide reasonable assistance to the initiating Party in connection with an infringement suit at no charge to the initiating Party except for reimbursement by the initiating Party of reasonable out-of-pocket expenses incurred in rendering such assistance. The non-initiating Party shall have the right to participate and be represented in any such suit by its own counsel at its own expense. If the Parties obtain from a Third Party, in connection with such suit, any damages, license fees, royalties or other compensation (including any amount received in settlement of such litigation) in respect of a Competitive Infringement, such amounts shall be allocated, subject to any adjustment to such allocation agreed by the Parties in connection with an agreement to jointly bear the costs and expenses of the infringement action as described above, as follows:

(iii)third, the remainder to be paid to the Party that did not receive the balance under clause (ii).

9.7.Third Party Infringement Claims. If a Party becomes aware of any claim that the Development, Manufacture or Commercialization of the Licensed Product in the Field infringes the Patent Rights of any Third Party in the Licensed Territory, such Party shall promptly notify the other Party. In any such instance, the Parties shall cooperate and shall mutually agree upon an appropriate course of action which may include settlement of such claim. Each Party shall have an equal right to participate in any settlement discussions that are held with such Third Parties.

9.8.Patent Marking. Each Party agrees to comply with the patent marking statutes in each country in which the Licensed Product is sold by such Party or its Affiliates or Sublicensees.

In addition, the Party using the Product Trademark of the other Party under this Section 9.9 shall comply strictly with the trademark style and usage standards of the Party that owns the Product Trademark as communicated to such Party from time to time with respect to the Product Trademarks. The Party using the Product Trademark of the other Party, shall, at the request and expense of the Party that owns the Product Trademark, from time to time, submit to the Party that owns the Product Trademark for approval a reasonable number of production samples of the Licensed Product and related packaging materials. If the Party that owns the Product Trademark reasonably objects to the quality of the Licensed Product or the usage of the Product Trademarks in connection with any sample, it shall give written notice of such objection to the other Party within sixty (60) days after receipt of the relevant sample, specifying the way in which such usage of the Product Trademarks fails to meet the style, usage or quality standards for the Licensed Product set forth in the second and third sentences of this Section 9.9(c), and such Party shall immediately cease sale and distribution of the Licensed Product using such Product Trademark. If the Party using such Product Trademark wishes to continue to distribute and sell the Licensed Product, it must remedy the failure and submit further samples to the Party that owns the Product Trademark for approval.

(d)Maintenance and Costs. If a Product Trademark owned by AVEO or any of its Affiliates or Sublicensees is used by Biogen Idec or any of its Affiliates or Sublicensees to promote and sell the Licensed Product in the Licensed Territory, then AVEO will use Commercially Reasonable Efforts to establish, maintain and enforce such Product Trademarks in the applicable countries of the Licensed Territory.

13.1.M&A Event Control Assumption Option. If, at any time during the Agreement Term, an M&A Event occurs involving AVEO (or any of its Affiliates) and a Person that, at the time of the consummation of such M&A Event, directly or indirectly (including by any Affiliate of such Person), is Developing or Commercializing a Directly Competitive Product in the AVEO Territory or the Licensed Territory within the Field or, at any time after such consummation of the M&A Event, develops or acquires a Directly Competitive Product (such Person being hereinafter referred to as a “Competing Acquiror”) and such Competing Acquiror has not, within six (6) months of either consummation of the M&A Event in the event the Directly Competitive Product is being Developed or Commercialized as of such consummation date or otherwise within six (6) months of the date of first development or acquisition of such Directly Competitive Product (the “Divestiture Period”) divested the Directly Competitive Product, terminated Development and Commercialization of such Directly Competitive Product or assigned this Agreement pursuant to Section 16.5 to a Third Party that is not itself Developing or Commercializing a Directly Competitive Product, then Biogen Idec may exercise, in the manner set forth further below in this Section 13.1, its right to trigger the provisions of this Section 13.1 (the “M&A Control Assumption Option”), whereupon (A) Biogen Idec shall assume the rights, responsibilities and obligations of AVEO under Articles IV and V of this Agreement with AVEO assuming the rights, responsibilities and obligations of Biogen Idec under such provisions, provided that notwithstanding anything to the contrary contained in Section 4.8(b), in the event the M&A Control Assumption Option is triggered, Biogen Idec will have final decision-making authority to increase or change the budget for Development Costs, and (B) Biogen Idec shall have the right (but not the obligation) to assume any or all of the rights, responsibilities and obligations of AVEO under Article VII and/or Article IX by giving AVEO at least 30 days prior written notice at any time and from time to time after the exercise of the M&A Control Assumption Option, which written notice shall specify the rights, responsibilities and obligations

TERM; TERMINATION AND REMEDIES FOR BREACH

14.1.Term. This Agreement shall become effective as of the Effective Date, and, in the event Biogen Idec does not exercise the Option by the end of the Option Exercise Period, shall terminate at the end of the Option Exercise Period, unless earlier terminated in accordance with this Article XIV. In the event Biogen Idec exercises the Option in accordance with Article II (or is deemed to have exercised the Option pursuant to Sections 13.1, 13.3 or 14.5(b)), this Agreement shall continue in full force until the later of (a) the last to expire Royalty Term and (b) such time as any Development activities that were pending before the expiration of the last to expire Royalty Term are no longer being conducted by either Party under this Agreement.

14.2.Termination for Convenience. Biogen Idec shall have the right to terminate this Agreement with respect to any Licensed Product at any time upon at least three months (3) months’ prior written notice to AVEO.

14.3.Remedies for Breach.

(a)Breach in Respect of Monetary Obligation. In the event that a Party is in material breach of this Agreement with respect to one of its financial obligations hereunder and has not cured such material breach within [**] after written notice describing the nature of such material breach is provided to the breaching Party, the non-breaching Party shall have the immediate right to elect its remedies for material breach set forth in Section 14.5.

(b)Breach in Respect of Non-Monetary Obligation. In the event a Party (the “Notifying Party”) is concerned that there has been or may be a failure by the other Party (the “Notified Party”) to meet one or more of its non-financial obligations under this Agreement and such failure constitutes, or could reasonably be expected to give rise to, a material breach of this Agreement, the Notifying Party shall send written notice to the Notified Party specifying in detail the nature of the concern and specifically referencing this Section 14.3(b) (a “Section 14.3 Notice”). Within [**] of delivery of such Section 14.3 Notice, the Parties shall meet to discuss the circumstances surrounding the perceived failure, the impediments that are impacting performance, the actions that the Parties believe are reasonably necessary to address such failure, and each Party’s view of the plan and timeline within which such failure could reasonably be remedied. If not originally provided with the Section 14.3 Notice, within [**] after the meeting held under the preceding sentence, the Notifying Party shall provide the Notified Party with a written plan that is prepared with a good faith intent to allow the Notified Party an adequate amount of time to address the perceived performance issues as determined in the reasonable discretion of the Notifying Party, and which shall include specific activities to be performed and the timeline for performance of such activities (the “Cure Plan”). Within [**] of receipt, the Notified Party shall provide written notice to the Notifying Party of its election to implement or not implement the Cure Plan. In the event the Notified Party either (A) fails to respond within such [**] period, (B) elects not to implement the Cure Plan within [**] of receipt of such Cure

Plan, or (C) elects to implement the Cure Plan, and thereafter fails to meet any milestone included in the Cure Plan, following written notice thereof by the Notifying Plan, and a one-time [**] opportunity to cure such milestone failure, then the Notifying Party shall have the right to elect its remedies for material breach as set forth in Section 14.5; provided that (i) the failure giving rise to the Section 14.3 Notice constitutes a material breach of this Agreement by the Notified Party and (ii) such material breach has not otherwise been cured on or prior to the [**] following the delivery of the Section 14.3 Notice applicable to such material breach. In the event the Notified Party elects to implement the Cure Plan within [**] of receipt thereof, and is continuing to execute in full compliance with such Cure Plan (subject to the one-time cure period for the first failed milestone under such Cure Plan), the Notifying Party’s right to elect its remedies for material breach as set forth in Section 14.5 shall be suspended until such time, if any, as the Notified Party fails to continue to execute in full compliance with the Cure Plan (e.g., such suspension shall immediately terminate upon the second failure to meet a milestone). Notwithstanding anything in this Agreement to the contrary, a Party’s decision whether or not to implement the Cure Plan shall not be deemed an admission or acknowledgement of breach nor will a failure to execute in accordance with the Cure Plan be considered a separate and independent breach of this Agreement.

14.4.Termination by Biogen Idec Upon Certain M&A Events. Without limiting any legal or equitable remedies that Biogen Idec may have, including under Section 13.1, in the event an M&A Event occurs involving AVEO (or any of its Affiliates) and a Person that, at the time of the consummation of such M&A Event, or at any time thereafter during the Agreement Term, directly or indirectly (including by any Affiliate), is Developing or Commercializing any Directly Competitive Product in the AVEO Territory or the Licensed Territory within the Field, then Biogen Idec shall have the right under this Section 14.4 to terminate this Agreement in its entirety by giving written notice of termination to AVEO and/or such Person.

Any termination of this Agreement pursuant to this Section 14.4 shall become effective on the date (the “Section 14.4 Termination Effective Date”) that is the later of (i) the effective date of termination specified in such written notice of termination given by Biogen Idec pursuant to this Section 14.4 or (ii) the last [**] of the [**] following the date in which such written notice of termination is given by Biogen Idec pursuant to this Section 14.4, if on or prior to such Section 14.4 Termination Effective Date such Person has not divested such Directly Competitive Product, terminated Development and Commercialization of such Directly Competitive Product or assigned this Agreement pursuant to Section 16.5 to a Third Party that is not itself Developing or Commercializing a Directly Competitive Product.
