 1.70 “Post-Approval Clinical Study” means (A) with respect to AVEO, any human clinical
trial or registry either (i) required to be carried out by a Regulatory Authority in the AVEO Territory for the purpose of post-marketing surveillance of Licensed Product in the AVEO Territory or (ii) otherwise requested by Regulatory
Authorities in the AVEO Territory after Regulatory Approval of Licensed Product in the AVEO Territory in an indication, designed to obtain additional information regarding Licensed Product’s risks, benefits and optimal use of that Licensed
Product in such indication, and (B) with respect to Biogen Idec, any human clinical trial or registry either (i) required to be carried out by a Regulatory Authority in the Licensed Territory for the purpose of post-marketing surveillance
of Licensed Product in the Licensed Territory or (ii) otherwise requested by Regulatory Authorities in the Licensed Territory after Regulatory Approval of Licensed Product in the Licensed Territory in an indication, designed to obtain
additional information regarding Licensed Product’s risks, benefits and optimal use of that Licensed Product in such indication. For purposes of clarity, a clinical trial of Licensed Product in an indication for which such Licensed Product is
not approved shall not be considered Post-Approval Clinical Study even if such trial occurs after such Licensed Product is approved in another indication. 
 1.71 “Pre-Option Exercise Phase 3 Manufacturing Costs” means the out-of-pocket costs and expenses incurred by AVEO or any of its Affiliates prior to the Option Exercise Date to obtain
quantities of Licensed Product (including drug substance, drug product, validation batches and material for stability and other testing) for a Phase 3 Clinical Trial or for Commercialization or for testing of Licensed Product for any such Phase 3
Clinical Trial. 
 1.72 “Proof of Concept Development Plan” means the written work-plan for AVEO’s

 12 








 1.73 “Proof of Concept Study” means a Phase 2 Clinical Trial that is
appropriately designed (i) to demonstrate efficacy in the disease to be studied through relevant primary and/or secondary efficacy endpoints as described in the Proof of Concept Development Plan and (ii) to allow dose selection and support
generation of efficacy data that would allow movement of the product into a Phase 3 Clinical Trial that would support the regulatory strategy of seeking Regulatory Approval in both the AVEO Territory and the EU. For purpose of clarity, a clinical
study meeting the requirements of this definition will be considered a Proof of Concept Study when completed whether or not the endpoints of the study are actually met. 
 1.74 “Regulatory Approval” means any approval, including price approval, registration, license or authorization from any Governmental Authority or Regulatory Authority required for the
Manufacture, Development or Commercialization of a Licensed Product in the Territory, and shall include, without limitation, an approval, registration, license or authorization granted in connection with the BLA. 
 1.75 “Regulatory Authority” means any federal, national, multinational, state, county, city, provincial, or local
regulatory agency, department, bureau or other governmental entity with authority over the Marketing, Commercialization, Manufacture or sale of a pharmaceutical product in the Territory, including the FDA in the United States and the EMEA in the EU.

as the case may be, under the AVEO Technology, Biogen Idec Collaboration Technology or Joint Collaboration IP, to Develop, Manufacture, Commercialize or use Licensed Product in the Field, or otherwise grants rights to distribute, promote or sell
Licensed Product in the Field, but does not include wholesale distributors of a Party or its Affiliates who purchase Licensed Product from such Party or its Affiliates in an arm’s length transaction. For purposes of clarity, the term
“wholesale distributors” does not include those distributors whose obligations to a Party or any of its Affiliates include responsibility for sales or marketing efforts in such country or sharing of costs and expenses with respect to sales
or marketing on behalf of a Party or its Affiliates, which such distributors shall be deemed Sublicensees for purposes of this definition. 
 1.79 “Territory” means, collectively, the AVEO Territory and the Licensed Territory. 
 1.80 “Territory-Specific Clinical Trial” means, with respect to AVEO, a human clinical trial specifically required in the AVEO Territory which will generate data that will not be
applicable to Licensed Product in the Licensed Territory (other than the

  

 13 








 
applicability of safety data) and, except with respect to safety data, will not be included in a filing for Regulatory Approval for Licensed Product in the Licensed Territory, and, with respect
to Biogen Idec, a human clinical trial specifically required in the Licensed Territory which will generate data that will not be applicable to Licensed Product in the AVEO Territory (other than the applicability of safety data) and, except with
respect to safety data, will not be included in a filing for Regulatory Approval for Licensed Product in the AVEO Territory.

reissue or disclaimer or otherwise or been dedicated to the public or (ii) a claim in a pending patent application that (A) is being prosecuted in good faith, (B) has not been abandoned or disclaimed or finally determined to be
unallowable by the applicable Governmental Authority in a decision from which no appeal is or can be taken, and (C) has not been pending for more than five (5) years from the date of issuance of the first substantive patent office action
considering the patentability of such claim by the applicable Governmental Authority in such country (at which time such pending claim shall cease to be a Valid Claim for purposes of this Agreement unless and until such claim becomes a claim of an
issued patent).

 ARTICLE II. 
 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”). 
  

 16 








 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

  

 17 








 
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

  

 18 








 
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.

asserting that the Development,

  

 19 








 
Manufacture or Commercialization of any AVEO Proprietary Composition Licensed Product by any member of the AVEO Group in the AVEO Territory within the Field pursuant to, and in accordance with,
the provisions of this Agreement infringes any Patent Rights owned and Controlled by Biogen Idec or any of its Affiliates (other than any such Patent Rights that are included in Biogen Idec Collaboration Patent Rights or Joint Collaboration Patent
Rights) that Cover the composition of matter or method of use of such AVEO Proprietary Composition Licensed Product and that are necessary to the Development, Manufacture or Commercialization of such AVEO Proprietary Composition Licensed Product in

notify the other Party of the particulars of the same and use Commercially Reasonable Efforts to enforce the terms of such license or sublicense. 
  

 21 








 (e) Performance by Contractors. If, and to the extent that, either Party has the
right or obligation pursuant to, and in accordance with, the provisions of this Agreement to Develop, Manufacture or Commercialize any Licensed Product, such Party shall be entitled to utilize the services of Third Parties (including Third Party
contract research organizations, Third Party contract manufacturing organizations (“CMOs”) and Third Party contract sales organizations (“CSOs”)) to perform the Development, Manufacturing or Commercialization activities that such
Party has the right or obligation to perform under this Agreement with respect to such Licensed Product; provided that the contracting Party shall remain at all times fully liable for its responsibilities under this Agreement. Neither
Party shall use Third Party contract resources to perform any activities that the contracting Party has the right or obligation to perform under this Agreement unless the contracting Party’s rights under the agreement with the Third Party
contractor guarantee to the other Party the same rights under this Agreement as if the contracting Party had performed such activities itself, and any such Third Party contractor agreement includes a requirement that such Third Party contractor
comply with the confidentiality provisions and restrictions on use of Confidential Information contained in Article X with respect to both Parties’ Confidential Information and a requirement that such Third Party contractor comply with any
other provisions required under any AVEO In-License or Biogen Idec In-License, as the case may be. Notwithstanding anything in this Agreement to the contrary, the contracting Party under this Section 3.3(e) shall (A) obtain from any Third
Party performing any activities of the contracting Party under this Agreement a license to any Know-how and Patent Rights generated by such Third Party arising directly out of the contracting activities to the extent necessary for the Development,
Manufacture and Commercialization of Licensed Product or to the extent such Know-how is incorporated in any Licensed Product or such Patent Rights Cover any Licensed Product, (B) if such Third Party or any of its Affiliates is a Sublicensee of
the contracting Party to whom the contracting Party has granted rights to Commercialize Licensed Product in the contracting Party’s Territory, obtain from such Third Party a license to any Know-how and Patent Rights generated by such Third
Party arising directly out of the contracting activities to the extent reasonably useful for the Development, Manufacture and Commercialization of Licensed Product and (C) use Commercially Reasonable Efforts to obtain from such Third Party
(other than a Third Party referred to in the foregoing clause (B)) a license to any Know-how and Patent Rights generated by such Third Party arising directly out of the contracting activities to the extent reasonably useful for the Development,
Manufacture and Commercialization of Licensed Product. Each such license referred to in the foregoing clause (A), (B) or (C) of this Section 3.3(e) shall include rights to both the AVEO Territory and the Licensed Territory to the
extent such Know-how and Patent Rights are necessary for the Development, Manufacture or Commercialization of Licensed Product in each such Territory or to the extent such Know-how is incorporated in any Licensed Product or such Patent Rights Cover
any Licensed Product. Each such license referred to in the foregoing clause (A), clause (B) or clause (C) of this Section 3.3(e) shall include the right to sublicense to the other Party consistent with this Agreement. For purposes of
clarification and not by way of limitation, it is understood and agreed that the term “necessary” as used in this Section 3.3(e) 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 the contracting Party to Develop, Manufacture or Commercialize,

  

 22 








 
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). 
 3.4. Restrictive Covenants. Except for the Development, Manufacture and Commercialization of Licensed
Products pursuant to, and in accordance with, the terms and conditions set forth in this Agreement and except for the grant of any licenses or sublicenses by AVEO with respect to Licensed Products pursuant to Section 3.3(b) above and except as
set forth in Section 3.9, during the Agreement Term neither AVEO nor any of its Affiliates (i) shall Develop, Manufacture or Commercialize any ERBB3 Antibody in the AVEO Territory or the Licensed Territory within the Field, (ii) shall
collaborate with any Third Party, shall grant to any Third Party the right, or shall engage in activities on behalf of any Third Party, to Develop, Manufacture or Commercialize any ERBB3 Antibody in the AVEO Territory or the Licensed Territory
within the Field, (iii) shall grant to any Third Party any license or other right under any AVEO Technology to Develop, Manufacture or Commercialize any ERBB3 Antibody in the AVEO Territory or the Licensed Territory within the Field or
(iv) subject to Section 16.5 hereof, shall sell, assign, convey or otherwise transfer any right, title or interest in and to any AVEO Technology or any ERBB3 Antibody (including, without limitation, any Licensed Product), provided
that the foregoing clause (iv) shall not be deemed a restriction on AVEO’s right to license AVEO Technology for any and all uses other than the Development, Manufacture or Commercialization of ERBB3 Antibodies or for any and all
uses outside the Field. 
 3.5. Retained Rights. Subject to Section 3.3(b) and Section 3.4, any rights of a
Party not expressly granted under this Agreement shall be retained by such Party. 
 3.6. Third Party Technology.

 (a) Process. 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

  

 23 








 
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

  

 24 








 
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

  

 25 








 
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

  

 26 








 
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 sue 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. 
  

 27 








 4.2. Chairperson. The chairperson of the JDC (the “JDC Chairperson”)

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. 
  

 28 








 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

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. 
  

 29 








 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.

Biogen Idec such other information related to prosecution of the AVEO Patent Rights and AVEO Collaboration Patent Rights in the Licensed Territory as Biogen Idec may from time to time reasonably request to allow Biogen Idec to track prosecution and
maintenance of such Patent Rights. In the event AVEO decides not to file a patent application on AVEO Know-how or AVEO Collaboration Know-how specific to Licensed Product in a country of the Licensed Territory, or decides to abandon prosecution of
any claim of an AVEO Patent Right or AVEO Collaboration Patent Right comprising claims Covering Licensed Product in a country of the Licensed Territory or decides to not otherwise maintain or extend any AVEO Patent Rights or AVEO Collaboration
Patent Right comprising claims Covering Licensed Product in a country of the Licensed Territory, AVEO shall give Biogen Idec written notice sufficiently in advance of any loss of rights to allow Biogen Idec to file, prosecute, maintain or extend, as
the case may be, such AVEO Patent Rights or AVEO Collaboration Patent Rights, in AVEO’s name, in such country. 
 (b)
Biogen Idec Collaboration Technology. Biogen Idec shall have the sole right, at Biogen Idec’s discretion, to file, conduct prosecution, and maintain (including the defense of any interference or opposition proceedings), all Patent Rights

specific to Licensed Product, or decides to abandon prosecution of any claim of Biogen Idec Collaboration Patent Right in a country of the Territory comprising claims Covering Licensed Product or decides to not otherwise maintain or extend any
Biogen Idec Collaboration Patent Right comprising claims Covering Licensed Product in a country of the Territory, Biogen Idec shall give AVEO written notice sufficiently in advance of any loss of rights to allow AVEO optionally to file, prosecute,
maintain or extend, as the case may be, such Biogen Idec Collaboration Patent Rights, in Biogen Idec’s name, in such country. 
 (c) Joint Collaboration IP. 
 (i) AVEO shall have the first right, at AVEO’s discretion, to
file, conduct prosecution, and maintain (including the defense of any interference or opposition proceedings), all Patent Rights included in Joint Collaboration IP, in the names of both AVEO and Biogen Idec. Biogen Idec shall use Commercially
Reasonable Efforts to make available to AVEO or its

  

 54 








 
authorized attorneys, agents or representatives, such of its employees as AVEO in its reasonable judgment deems necessary in order to assist it in obtaining patent protection for such Joint
Collaboration IP. Each Party shall sign, or use Commercially Reasonable Efforts to have signed, all legal documents necessary to file and prosecute patent applications or to obtain or maintain patents in respect of such Joint Collaboration IP, at
its own cost. 
 (ii) If AVEO elects not to seek or continue to seek or maintain patent protection on any Joint
Collaboration IP in the Licensed Territory, Biogen Idec shall have the right, at Biogen Idec’s discretion, to seek, prosecute and maintain in any country in the Licensed Territory patent protection on such Joint Collaboration IP in the names of
both AVEO and Biogen Idec. AVEO shall use Commercially Reasonable Efforts to make available to Biogen Idec its authorized attorneys, agents or representatives, such of AVEO’s employees as are reasonably necessary to assist Biogen Idec in
obtaining and maintaining the patent protection described under this Section 9.3(c)(ii). AVEO shall sign or use Commercially Reasonable Efforts to have signed all legal documents necessary to file and prosecute such patent applications or to
obtain or maintain such patents. 
 (iii) With respect to Patent Rights included in the Joint Collaboration IP,
the Party filing, prosecuting and maintaining such Patent Rights shall provide the other Party, within ten (10) Business Days after submitting or receiving such filings or correspondence, with copies of all filings and correspondence submitted
to and received from patent offices in the Licensed Territory and, with respect to substantive filings and correspondence to be submitted to patent offices in the Licensed Territory, shall use reasonable efforts to provide the other Party with
drafts of such filings and correspondence reasonably in advance of submission and shall consider in good faith any comments regarding such filings and correspondence that the other Party may timely provide. 
 9.4. Patent Term Extensions. The Parties shall cooperate, if necessary and appropriate, with each other in gaining patent term
extension (including those extensions available under U.S. Drug Price Competition and Patent Term Restoration Act of 1984, the Supplementary Certificate of Protection of Member States of the EU and other similar measures in any other country)
wherever applicable to Patent Rights Controlled by either Party that Cover the Licensed Product in the Territory. The Parties shall, if necessary and appropriate, use reasonable efforts to agree upon a joint strategy relating to patent term
extensions, but, in the absence of mutual agreement with respect to any extension issue, the patent or the claims of the patent shall be selected on the basis of the scope, enforceability and remaining term of the patent in the relevant country or
region. All filings for such extensions shall be made by the Party owning such patent or, in the case of Patent Rights included in the Joint Collaboration IP, by the Party responsible for filing, prosecuting and maintaining such Patent Rights in
accordance with this Section 9.4. 
 9.5. Patent Expenses. The patent filing, prosecution and maintenance expenses
incurred after the Option Exercise Date under Section 9.3 with respect to AVEO Patent Rights, AVEO Collaboration Patent Rights, Biogen Idec Collaboration Patent Rights and Joint Collaboration Patent Rights, in each case with claims covering
Licensed Product in the Licensed Territory shall be borne by

  

 55 








 
Biogen Idec. The patent filing, prosecution and maintenance expenses incurred under Section 9.3 with respect to AVEO Patent Rights, AVEO Collaboration Patent Rights, Biogen Idec
Collaboration Patent Rights and Joint Collaboration Patent Rights in each case with claims covering Licensed Product in the AVEO Territory shall be borne by AVEO. In all other cases, the patent filing, prosecution and maintenance expenses incurred
during the Agreement Term with respect to Patent Rights comprised of AVEO Technology and Biogen Idec Collaboration Technology (“Patent Expenses”) shall be borne by the Party responsible for filing, prosecuting and maintaining such
Patent Rights under this Section 9.5. 
 9.6. Third Party Infringement. 
 (a) Notices. Each Party shall promptly report in writing to the other Party any (i) known or suspected infringement of any AVEO
Technology or Biogen Idec Collaboration Technology, including any Joint Collaboration IP or (ii) unauthorized use or misappropriation of any Confidential Information or Know-how of a Party by a Third Party of which it becomes aware, in each
case only to the extent relevant to the Licensed Product or the Development, Manufacture or Commercialization of the Licensed Product and involving a competing product (“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

  

 56 








 
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: 
 (i) first, to reimburse each Party for all expenses of
the suit incurred by such Party, including attorneys’ fees and disbursements, court costs and other litigation expenses; 
 (ii) second, [**] percent ([**]%) of the balance to be paid to (x) AVEO, in respect of a Competitive Infringement in the AVEO Territory, and (y) Biogen Idec, in respect of a Competitive
Infringement in the Licensed Territory, as the case may be; and 
  

 57 








 (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. 
 9.9. Trademarks. 
 (a) Corporate Names and Logos. Each Party and its Affiliates shall retain all right, title and interest in and to its and their
respective corporate names and logos. 
 (b) Creation and Registration of Trademarks. AVEO or its Affiliates or
Sublicensees will create and register product trademarks for use with Licensed Product throughout the AVEO Territory, and Biogen Idec or its Affiliates or Sublicensees will create and register product trademarks for use with Licensed Product
throughout the Licensed Territory (collectively, the “Product Trademarks”). Each Party (or its Affiliates or Sublicensees, as appropriate) shall own all rights to its Product Trademarks, and all goodwill associated therewith,
throughout the world, and to any Internet domain names incorporating the applicable Product Trademarks or any variation or part of such Product Trademarks used as its URL address or any part of such address. 
 (c) License to Trademarks. AVEO shall grant to Biogen Idec and its Affiliates and Sublicensees an exclusive license to use
AVEO’s Product Trademarks to Commercialize the Licensed Product in the Field in the Licensed Territory, and Biogen Idec shall grant to AVEO and its Affiliates and Sublicensees an exclusive license to use Biogen Idec’s Product Trademarks to
Commercialize the Licensed Product in the Field in the AVEO Territory. If a Party uses the Product Trademark of the other Party with respect to Licensed Product, as permitted under this Agreement, such Party agrees that the quality of the Licensed
Product and the Commercialization thereof shall be consistent with the quality standards applied by the owner of the Product Trademark thereto. 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

  

 58 








 
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. Biogen Idec shall be responsible for [**] of the costs of such efforts in the Licensed Territory and Biogen Idec shall reimburse AVEO for all such costs incurred by AVEO within [**] after receiving any invoice
from AVEO for such costs. If a Product Trademark owned by Biogen Idec or any of its Affiliates or Sublicensees is used by AVEO or any of its Affiliates or Sublicensees to promote and sell the Licensed Product in the AVEO Territory, then Biogen Idec
will use Commercially Reasonable Efforts to establish, maintain and enforce such Product Trademarks in the applicable countries in the AVEO Territory. AVEO shall be responsible for [**] of the costs of such efforts in the AVEO Territory and AVEO
shall reimburse Biogen Idec for all such costs incurred by Biogen Idec within [**] after receiving any invoice from AVEO for such costs. 
 (e) Infringement of Trademarks. If either Party becomes aware of any infringement of any Product Trademark by a Third Party in the Licensed Territory, such Party shall promptly notify the other
Party and the Parties shall consult with each other and jointly determine the best way to prevent such infringement, including by the institution of legal proceedings against such Third Party. 
 ARTICLE X.

 10.1. Confidential Information. During the Agreement Term and for a period of ten (10) years after any termination or expiration
hereof, each Party agrees to keep in confidence and not to disclose to any Third Party, or use for any purpose, except pursuant to, and in order to carry out, the terms and objectives of this Agreement, any Confidential Information of the other
Party. The terms of this Agreement shall be considered Confidential Information of both Parties hereunder. The restrictions on the disclosure and use of Confidential Information set forth in the first sentence of this Section 10.1 shall not
apply to any Confidential Information that: 
 (i) was known by the receiving Party prior to disclosure by the
disclosing Party hereunder (as evidenced by the receiving Party’s written records or other competent evidence); 
  

 59 








 (ii) is or becomes part of the public domain through no fault of the
receiving Party; 
 (iii) is disclosed to the receiving Party by a Third Party having a legal right to make such
disclosure without violating any confidentiality or non-use obligation that such Third Party has to the disclosing Party and provided such third party is not disclosing such information on behalf of the disclosing Party; or 
 (iv) is independently developed by personnel of the receiving Party who did not have access to the relevant Confidential
Information of the other Party (as evidenced by the receiving Party’s written records or other competent evidence). 
 In addition, if
either Party is required to disclose Confidential Information of the other Party by regulation, law or legal process, including by the rules or regulations of the United States Securities and Exchange Commission, or similar regulatory agency in a
country other than the United States, or of any stock exchange or Nasdaq, such Party shall provide prior written notice and a copy of such intended disclosure to such other Party if possible under the circumstances to enable such other Party to seek
a protective order or other appropriate remedy concerning any such disclosure, shall consider in good faith the other Party’s comments and reasonably cooperate (at the expense of the Party seeking to restrict such disclosure) to obtain any such
order or other remedy, and shall disclose only such Confidential Information of such other Party as is legally required to be disclosed. In addition, either Party may disclose to bona fide potential investors or lenders, potential
acquirors/acquirees, existing or potential collaborators or licensees or to such Party’s consultants and advisors, the existence and terms of this Agreement to the extent necessary in connection with a proposed equity or debt financing of such
Party, or a proposed acquisition or business combination, so long as such recipients are bound in writing to maintain the confidentiality of such information in accordance with the terms of this Agreement 
 10.2. Permitted Disclosures. Each Party agrees that it and its Affiliates shall provide or permit access to Confidential Information
received from the other Party and such Party’s Affiliates and representatives only to the receiving Party’s employees, consultants, advisors and permitted subcontractors, Sublicensees and sub-distributors, and to the employees,
consultants, advisors and permitted subcontractors, Sublicensees and sub-distributors of the receiving Party’s Affiliates, who in such Party’s reasonable judgment have a need to know such Confidential Information to assist the receiving
Party with the activities contemplated by this Agreement and who are subject to obligations of confidentiality and non-use with respect to such Confidential Information similar to the obligations of confidentiality and non-use of the receiving Party
pursuant to Section 10.1; provided that AVEO and Biogen Idec shall each remain responsible for any failure by its Affiliates, and its and its Affiliates’ respective employees, consultants, advisors and permitted
subcontractors, Sublicensees and sub-distributors, to treat such Confidential Information as required under Section 10.1 (as if such Affiliates, employees, consultants, advisors and permitted subcontractors, Sublicensees and sub-distributors
were Parties directly bound to the requirements of Section 10.1). Each Party may also disclose Confidential Information of the other Party to Regulatory Authorities, but solely in connection with the activities contemplated by this Agreement.

  

 60 








 10.3. Publicity. Upon the execution of this Agreement, AVEO shall be entitled to
issue a mutually agreed press release regarding the subject matter of this Agreement in the form attached as Exhibit E (the “Initial Release”). After such Initial Release, neither Party shall issue a press release or public
announcement relating to this Agreement without the prior written approval of the other Party, which approval shall not be unreasonably withheld or delayed, except that (i) a Party may issue such a press release or public announcement if the
contents of such press release or public announcement have been previously been made public pursuant to the Initial Release or otherwise, other than through a breach of this Agreement by the issuing Party, (ii) a Party may issue such a press
release or public announcement if required by applicable Law, including by the rules or regulations of the United States Securities and Exchange Commission (SEC) or similar regulatory agency in a country other than the United States or of any stock

Product (without use of Biogen Idec’s or any of its Affiliates name), subject in each case to the next sentence. In the event of disclosures under clause (ii) or (iii) of the foregoing sentence, and during the License Term, under
clause (iv), the Party planning to make such disclosure shall first notify the other Party of such planned press release or public announcement at least three Business Days in advance of issuing such press release or making such public announcement
(or, with respect to press releases and public announcements made pursuant to the foregoing clause (ii) or (iii), with as much advance notice as possible under the circumstances if it is not possible to provide notice at least three Business
Days in advance) for the sole purpose of allowing the other Party to review the proposed press release or public announcement for the inclusion of its Confidential Information or the use of its name; provided that the Party subject to
the requirement shall include in such press release or public announcement made pursuant to the foregoing clause (ii) or (iii) only such information relating to the Licensed Product or this Agreement as is required by such applicable Law.

 10.4. Publications. 
 (a) Option Exercise Period. During the Option Exercise Period, AVEO shall be free to publish the results of Development carried out on the Licensed Product. 
 (b) License Term. During the License Term, subject to the restrictions provided below, the JDC shall determine the publication
strategy for the Territory. In the event, either Party, consistent with the publication strategy adopted by the JDC, proposes to publish or present the results of Development carried out on the Licensed Product, such publication or presentation
shall be subject to the prior review by the other Party for patentability and protection of such other Party’s Confidential Information. Each Party shall provide to the other Party the opportunity to review any proposed abstracts, manuscripts
or summaries of presentations that cover the results of Development of the Licensed Product during the License Term. Each Party shall designate a person or persons who shall be responsible for reviewing such publications. Such designated person
shall respond in writing promptly and in no event later than thirty (30) days after receipt of the proposed material with either approval of the proposed material or a specific statement of concern, based upon either the need to seek patent
protection or concern regarding competitive disadvantage arising from the proposal. In the

  

 61 








 
event of concern, the submitting Party agrees not to submit such publication or to make such presentation that contains such information until the other Party is given a reasonable period of time
(not to exceed sixty (60) days) to seek patent protection for any material in such publication or presentation that it believes is patentable or to resolve any other issues, and the submitting Party shall remove from such proposed publication
any Confidential Information of the other Party as requested by such other Party. With respect to any proposed abstracts, manuscripts or summaries of presentations by investigators or other Third Parties, including Affiliates or Sublicensees, such
materials shall be subject to review under this Section 10.4 to the extent that the contracting Party has the right to do so, provided that each Party agrees to use Commercially Reasonable Efforts to include in any agreement with investigators
and other Third Parties a right for both Parties to review publications and presentations consistent with the terms of this Section 10.4.

 ARTICLE XIII. 
 CONTROL ASSUMPTION OPTIONS 
 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

  

 66 








 
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 of AVEO under Article
VII and/or IX being assumed by Biogen Idec. In the event that Biogen Idec exercises the M&A Control Assumption Option prior to the Option Exercise Date, (i) the provisions of Article II shall terminate (except to the extent otherwise
provided in clause (iii) below), (ii) the exercise of the M&A Control Assumption Option shall be deemed, for all purposes of this Agreement, to be the exercise of the Option by Biogen Idec, (iii) Biogen Idec shall be responsible
for preparing and delivering to AVEO the Delivered Initial Development Plan and, if at the time of delivery of such plan, AVEO has not previously delivered the Data Package to Biogen Idec, such plan shall set forth Biogen Idec’s Development
efforts in connection with the Proof of Concept Study, and, if at the time of the delivery of such plan, AVEO has previously delivered the Data Package to Biogen Idec, such plan shall meet the criteria therefor set forth in clauses (ii) and
(iii) of Section 2.9 and (iv) if the Delivered Initial Development Plan provides for the conduct of the Proof of Concept Study in accordance with the provisions of the foregoing clause (iii), AVEO shall be obligated to pay and
reimburse Biogen Idec for all costs and expenses incurred by Biogen Idec in connection with the Development and Manufacture of Licensed Product through the completion of the Proof of Concept Study for a single indication, and upon completion of the
Proof of Concept Study Biogen Idec shall reimburse AVEO for [**] of the Pre-Phase 3 Manufacturing Costs. For purposes of this Section 13.1, (x) any reference in the definition of “Proof of Concept Study” to the Proof of Concept
Development Plan shall be deemed to be a reference to the Delivered Initial Development Plan provided pursuant to this Section 13.1, and (y) any reference in the definition of “Pre-Phase 3 Manufacturing Costs” to the Option
Exercise Date shall be deemed to be a reference to the date of the completion of the Proof of Concept Study. In addition, upon exercise of the M&A Control Assumption Option, the royalties payable by Biogen Idec under Section 8.5 shall be
reduced by [**]. The M&A Control Assumption Option shall be exercised by providing written notice to AVEO no later than [**] after the date that AVEO and/or the Competing Acquiror sends written notice to Biogen Idec stating that the Divestiture
Period has expired and that Biogen Idec may exercise its rights under this Section 13.1. In addition to the foregoing

  

 67 








 
obligations, in the event Biogen Idec exercise its M&A Control Assumption Option under this paragraph, it shall thereafter provide to AVEO copies of filings, submissions and correspondence
with respect to AVEO Technology under Section 9.3(a) in the AVEO Territory and consider AVEO’s comments to the same extent as AVEO provides such information and considers Biogen Idec’s comments with respect to AVEO Technology under
Section 9.3(a) prior to the exercise of the M&A Control Assumption Option. 
 13.2. Termination Right. The
provisions of Section 13.1 shall not be deemed to limit Biogen Idec’s right under Section 14.5 with respect to consummation of an M&A Event involving AVEO or any of its Affiliates and a Competing Acquiror. 
 13.3. Insolvency Control Assumption Option. Without limiting any legal or equitable remedies that Biogen Idec may have, including
under this Article XIII, if, at any time during the Agreement Term, an Insolvency Event involving AVEO occurs, then Biogen Idec may exercise, in the manner set forth further below in this Section 13.3, its right to trigger the provisions of
this Section 13.3 (the “Insolvency 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 Insolvency 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

responsibilities and obligations of AVEO under Article VII and/or IX being assumed by Biogen Idec. In the event that Biogen Idec exercises the Insolvency Control Assumption Option prior to the Option Exercise Date, (i) the provisions of Article
II shall terminate (except to the extent otherwise provided in clause (iv) below), (ii) the exercise of the Insolvency Control Assumption Option shall be deemed, for all purposes of this Agreement, to be the exercise of the Option by
Biogen Idec, (iii) the royalties payable by Biogen Idec under Section 8.5 shall be reduced by [**], (iv) Biogen Idec shall be responsible for preparing and delivering to AVEO the Delivered Initial Development Plan and, if at the time
of delivery of such plan, AVEO has not previously delivered the Data Package to Biogen Idec, such plan shall set forth Biogen Idec’s Development efforts in connection with the Proof of Concept Study, and, if at the time of the delivery of such
plan, AVEO has previously delivered the Data Package to Biogen Idec, such plan shall meet the criteria therefor set forth in clauses (ii) and (iii) of Section 2.9 and (v) if the Delivered Initial Development Plan provides for the
conduct of the Proof of Concept Study in accordance with the provisions of the foregoing clause (iv), AVEO shall be obligated to pay and reimburse Biogen Idec for all costs and expenses incurred by Biogen Idec in connection with the Development and
Manufacture of Licensed Product through the completion of the Proof of Concept Study for a single indication, and upon completion of the Proof of Concept Study Biogen Idec shall reimburse AVEO for [**] of the Pre-Phase 3 Manufacturing Costs. For
purposes of this Section 13.3, (x) any reference in the definition of “Proof of Concept Study” to the Proof of Concept Development Plan shall be deemed to be a reference to the Delivered Initial Development Plan provided pursuant
to this Section 13.3, and (y) any

  

 68 








 
reference in the definition of “Pre-Phase 3 Manufacturing Costs” to the Option Exercise Date shall be deemed to be a reference to the date of the completion of the Proof of Concept
Study. The Insolvency Control Assumption Option shall be exercised by providing written notice to AVEO no later than [**] after the Insolvency Event with respect to AVEO. In addition to the foregoing obligations, in the event Biogen Idec exercise
its Insolvency Control Assumption Option under this paragraph, it shall thereafter provide to AVEO copies of filings, submissions and correspondence with respect to AVEO Technology under Section 9.3(a) in the AVEO Territory and consider
AVEO’s comments to the same extent as AVEO provides such information and considers Biogen Idec’s comments with respect to AVEO Technology under Section 9.3(a) prior to the exercise of the Insolvency Control Assumption Option. For
purposes of this Agreement, the term “Insolvency Event” means that AVEO (i) commits an act of bankruptcy, is declared bankrupt, voluntarily files or has filed against it a petition for bankruptcy or reorganization unless such
petition is dismissed within sixty (60) days of filing or such petition is for a reorganization under Chapter 11 of the Bankruptcy Code (as defined below) or any relevant foreign equivalent thereof and AVEO is not in default at the time of the
filing of such petition or at any time during such reorganization of any of its obligations under this Agreement, (ii) enters into a procedure of winding up or dissolution, or (iii) should a trustee or receiver be appointed for its
business assets or operations. All rights and licenses granted under or pursuant to this Agreement are, and shall otherwise be deemed to be, for the purposes of Section 365(n) of Title 11, U.S. Code (“Bankruptcy Code”) license
rights to “intellectual property” as defined under Section 101(60) of the Bankruptcy Code. The Parties agree that any Party, as a licensee hereunder, shall retain and may fully exercise all of its rights and elections under the
Bankruptcy Code or any relevant foreign equivalent thereof. 
 ARTICLE XIV. 
 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. 
  

 69 








 (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

  

 70 








 
its entirety by giving written notice of termination to AVEO and/or such Person. Such written notice of termination shall specify that it is being given by Biogen Idec pursuant to this
Section 14.4 and must be given within [**] after the later of (i) the date of the consummation of the M&A Event and (ii) the date that AVEO and/or such Person sends written notice to Biogen Idec stating that the M&A Event has
been consummated and that Biogen Idec may terminate this Agreement pursuant to this Section 14.4. 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. 

14.5. Special Remedies for Breach. 
 (a) AVEO Remedy for Breach by Biogen Idec. Without limiting any other legal or equitable remedies that AVEO may have, in the event of any material breach of the Agreement by Biogen Idec that occurs
during the Option Exercise Period, that has not been cured by Biogen Idec in accordance with the provisions of Section 14.3 and in respect of which AVEO elects, in accordance with the provisions of Section 14.3, to pursue its remedies
under this Section 14.5(a), the Option shall immediately terminate, and Biogen Idec shall have no further right to exercise the Option. Without limiting any other legal or equitable remedies that AVEO may have, in the event of any material
breach of the Agreement by Biogen Idec that occurs during the License Term, that has not been cured by Biogen Idec in accordance with the provisions of Section 14.3 and in respect of which AVEO elects, in accordance with the provisions of
Section 14.3, to pursue its remedies under this Section 14.5(a), this Agreement shall continue in full force and effect subject to the automatic modification thereof as follows:

Licensed Product being referred to as a “Breached Licensed Product”); 
 (iii) The licenses and
rights granted to AVEO pursuant to Section 3.2(a) shall continue with respect to the Breached Licensed Product and be converted automatically to worldwide licenses and rights with respect to the Breached Licensed Product such that AVEO and its
Affiliates and Sublicensees shall have the right under such converted worldwide licenses and rights to Develop, Manufacture and Commercialize such Breached Licensed Product in the AVEO Territory and the

  

 71 








 
Licensed Territory, and AVEO shall continue to have the right to grant sublicenses (subject to provisions similar to those set forth in Section 3.3 (other than subclauses (i), (ii) and
(vi) of Section 3.3(b)) that are applicable to sublicenses of licenses granted by Biogen Idec to AVEO pursuant to Section 3.2(a) hereof); 
 (iv) Responsibility and control over the Development of the Breached Licensed Product shall rest solely with AVEO and the JDC shall have no decision-making authority with respect to such Breached Licensed
Product and AVEO shall use Commercially Reasonable Efforts during the License Term to Develop the Breached Licensed Product in the Field for both the Licensed Territory and the AVEO Territory; 
 (v) Responsibility and control over the Commercialization of the Breached Licensed Product in the AVEO Territory and the
Licensed Territory shall rest solely with AVEO and AVEO shall use Commercially Reasonable Efforts to Commercialize such Breached Licensed Products in those countries in the AVEO Territory and the Licensed Territory in which Regulatory Approval has
been obtained, including by providing appropriate incentives consistent with its normal business practices to Sales Representatives involved in the Commercialization of the Licensed Product in the AVEO Territory; 
 (vi) Neither Party shall have any further obligation under Article V or Article VI with respect to the Breached Licensed
Product;

shall terminate; 
 (viii) AVEO’s obligations under Article VIII with respect to the Breached Licensed
Product shall continue (including, without limitation, the obligation thereunder to make payment of royalties), provided that the royalties that AVEO is required to pay Biogen Idec under Article VIII with respect to the Breached Licensed Product
shall be increased by [**] if AVEO exercises its rights under this Section 14.5(a) with respect to the Breached Licensed Product prior to Regulatory Approval thereof in the Licensed Territory and shall be increased by [**] if AVEO exercises its
rights under this Section 14.5(a) with respect to the Breached Licensed Product after Regulatory Approval thereof in the Licensed Territory; 
 (ix) AVEO shall make payment to Biogen Idec of royalties on Net Sales of the Breached Licensed Product in the Licensed Territory by AVEO and its Affiliates and Sublicensees (the terms of Article VIII and
the foregoing clause (viii) shall apply to AVEO’s obligation to pay royalties under this clause (ix) to the same extent as they apply to AVEO’s obligation to pay royalties on Net Sales of the Breached Licensed Product in the AVEO
Territory by AVEO and its Affiliates and Sublicensees); 
 (x) AVEO shall have the right (but not the obligation)
to assume any or all of the rights, responsibilities and obligations of Biogen Idec under Article IX with respect to the Breached Licensed Product by giving Biogen Idec at least [**] prior written notice at any time and from time to time after the
exercise by AVEO of its special remedies under this

lists and customer contact information and all Safety Data and other adverse event data in Biogen Idec’s possession or Control, and (C) all records and materials in Biogen Idec’s possession or Control containing Confidential
Information of AVEO with respect to the Breached Licensed Product; 
 (xii) If the Breached Licensed Product is
being Commercialized by Biogen Idec in any country in the Licensed Territory, then, if requested by AVEO, Biogen Idec shall appoint AVEO as its exclusive distributor of the Breached Licensed Product in the Licensed Territory and grant AVEO the right
to appoint sub-distributors, until the earlier of (A) such time as all Regulatory Approvals in the Licensed Territory with respect to the Breached Licensed Product have been transferred to AVEO or its designee and (B) [**] after AVEO has
exercised its special remedies under this Section 14.5(a) with respect to the Breached Licensed Product; 
 (xiii) If AVEO so requests, Biogen Idec shall transfer to AVEO any Third Party agreements to which Biogen Idec is a party relating to the Development, Manufacture or Commercialization of the Breached Licensed Product in the AVEO Territory
or the Licensed Territory, subject to any required consents of such Third Party;

will contain any untrue statement of a material fact or omits or will omit to state a material fact necessary in order to make the statements contained herein or therein, in light of the circumstances under which they were made, not misleading. To
the Company’s knowledge, there is no material fact directly relating to the business, operations or financial condition of the Company (including any competitive developments but other than facts that relate to general economic or industry

effect that such registration is not required.”

 AVEO and Biogen Idec Form Strategic Alliance for Development and Commercialization 
 of ErbB3-Targeted
Antibodies 
 Biogen Idec to Obtain to Commercialize ErbB3 Antibodies Outside of North America 
 CAMBRIDGE, Mass., February xx, 2009 – AVEO Pharmaceuticals, Inc., a biopharmaceutical company leveraging breakthrough discoveries in cancer
biology to discover, develop and commercialize targeted oncology therapies, today announced a definitive agreement with Biogen Idec, Inc. (NASDAQ:BIIB), for the development and commercialization of AVEO’s novel discovery-stage ErbB3-targeted
antibodies (the “ErbB3 program”) for the potential treatment of cancer and other diseases. 
 Under the terms of the agreement, AVEO
will receive an up-front payment and is eligible to receive milestone payments based upon the achievement of specified development goals. Biogen Idec will have an option exercisable at proof of concept to development and commercialization rights to
ErbB3 binding antibodies for territories outside of North America. AVEO retains all North American commercialization rights, and is responsible for leading global development of the ErbB3 program. Financial terms of the transaction were not
disclosed. 
 “We are very please to enter into this alliance with Biogen Idec,” stated Tuan Ha-Ngoc, president and chief executive
officer of AVEO. “This agreement for the development and commercialization of our discovery-stage ErbB3-targeted antibodies facilitates our strategy to develop a balanced portfolio of small molecule drugs and antibodies for the treatment of
cancer. These alliances highlight AVEO’s ability to generate value from our antibody discovery programs and advance these candidates to the clinic, reinforcing the broad potential of our rapidly maturing proprietary antibody pipeline and the
quality of our science. The terms of this alliance with Biogen Idec support our strategy to become a fully-integrated company offering first- and best-in-class cancer medicines through AVEO’s own North American-based commercial
organization.” 







 ErbB3 is a type 1 tyrosine kinase receptor of the EFGR family that is widely expressed in human carcinomas,
with demonstrated overexpression – correlated with poor prognosis – in several different tumor types, including breast, ovarian, prostate, colorectal, pancreatic, gastric and head & neck cancers. In vivo studies conducted
by AVEO demonstrated that elevated ErbB3 levels can potently drive breast tumor growth and may provide an escape mechanism to Herceptin® treatment. ErbB3 is also implicated in the development of resistance to EGFR tyrosine kinase inhibitors in
non small cell lung cancer. AVEO has focused its ErbB3 antibody discovery efforts on identifying high affinity, high specificity antibodies that recognize ErbB3 on the cell surface and inhibit its activity. The market attractiveness of AVEO’s
ErbB3 portfolio is bolstered by the success of other EFGR family inhibitors such as erlotinib, gefitinib and transtuzumab, which have unique patterns of resistance that may be addressed by an effective ErbB3 antibody. 
 About AVEO 
 AVEO is a late-stage
biopharmaceutical company focused on the discovery and development of novel, targeted cancer therapeutics. AVEO’s proprietary, integrated cancer biology platform enables the company to pursue highly efficient drug development strategies in
oncology that increase the probability of clinical success and provides a discovery engine for high-value targets. This approach has resulted in a balanced pipeline of novel cancer therapies focused on well-validated targets (VEGFR, EGFR) and
promising novel targets (HGF, FGFR, ERBB3), as well as collaborations with Eli Lilly, Merck, OSI Pharmaceuticals, Schering-Plough and Biogen Idec. The company’s lead product, AV-951, a potential best-in-class triple VEGF receptor inhibitor, is
in a Phase 2 clinical trial in patients with metastatic renal cell cancer and is expected to enter Phase 3 development in 2009. Through a combination of internal drug discovery and selective in-licensing of targeted therapeutics, AVEO is building a
diversified product pipeline and moving toward its vision of becoming a fully integrated pharmaceutical company. For more information, please visit the company’s website at www.aveopharma.com.
