continue in full force and effect as such licenses relate to Non-MAP Collaboration Targets for which the Option has been exercised prior to the date of termination of the Research Program, and (B) the licenses granted to MERCK pursuant to
Sections 3.1.4 shall continue in full force and effect as such licenses relate to MAP Collaboration Targets for which the MAP Technology Access Fee has been paid prior to the date of termination of the Research Program; and (iv) except for the
provisions of this Article 2, the rights and obligations of the Parties hereunder shall continue after the date of such termination of the Research Program, but subject to the modifications set forth in this Section 2.8.4. 

 

	2.9	INTENTIONALLY OMITTED 

  

	2.10 	Pilot Experiments 

 AVEO used an appropriate portion of the funding provided by MERCK prior to the Restatement Effective Date pursuant to Section 5.2 to perform the Pilot Experiments. In the event the Pilot Experiments are successful, the Parties may
choose to enter into a collaboration and license agreement for the responder identification technology that is the subject of the Pilot Experiments and, if MERCK and AVEO so choose, MERCK and AVEO shall negotiate a separate agreement, with separate
financial provisions, regarding a research collaboration and license for such technology, provided that neither Party shall be obligated to enter into such an agreement. AVEO shall own data generated in the performance of the Pilot
Experiments, and MERCK shall have the right to use such data for Internal Research Purposes. 
  

 -17- 

	2.11	Compliance 

 AVEO
and MERCK shall conduct the Research Program in accordance with all applicable laws, rules and regulations, including, without limitation, all current governmental regulatory requirements concerning Good Laboratory Practices. In addition, if animals
are used in research hereunder, AVEO and MERCK will comply with the Animal Welfare Act or any other applicable local, state, national and international laws or regulations relating to the care and use of laboratory animals. The Parties are each
encouraged to use the highest standards, such as those set forth in the Guide for the Care and Use of Laboratory Animals (NRC, 1996), for the humane handling, care and treatment of such research animals. Any animals which are used in the course of
the Research Program, or products derived from those animals, such as eggs or milk, will not be used for food purposes, nor will these animals be used for commercial breeding purposes. AVEO and MERCK shall notify each other in writing of any
deviations from applicable regulatory or legal requirements. Each Party hereby certifies that it will not and has not employed or otherwise used in any capacity the services of any person debarred under Section 21 USC 335a in performing any
services hereunder. 
  

	2.12	Exclusive Efforts 

 During the Research Program Term, AVEO shall work exclusively (even as to AVEO itself) with MERCK to use the Collaboration Models to discover Potential Collaboration Targets for use in the Field; provided, however, this
Section 2.12 shall not limit in any way AVEO’s freedom to fully exploit any right not licensed exclusively to MERCK under this Agreement, or any right which reverts to AVEO under this Agreement, including, without limitation, the freedom
to exploit for any purpose any AVEO Targets.

 -20- 

	3.3	Section 365(n) of the Bankruptcy Code 

 All rights and licenses granted under or pursuant to any section of this Agreement are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of
rights to “intellectual property” as defined under Section 101(35A) of the U.S. Bankruptcy Code. The Parties shall retain and may fully exercise all of their respective rights and elections under the U.S. Bankruptcy Code. The Parties
agree that MERCK, as a licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code, and that upon commencement of a bankruptcy proceeding by or against AVEO under
the U.S. Bankruptcy Code, MERCK shall be entitled to a complete duplicate of or complete access to (as MERCK deems appropriate), any such intellectual property and all embodiments of such intellectual property, provided MERCK continues to fulfill
its payment and/or royalty obligations as specified herein in full. Such intellectual property and all embodiments thereof shall be promptly delivered to MERCK (i) upon any such commencement of a bankruptcy proceeding upon written request
therefore by MERCK, unless AVEO elects to continue to perform all of its obligations under this Agreement or (ii) if not delivered under (i) above, upon the rejection of this Agreement by or on behalf of AVEO upon written request therefore
by MERCK. The foregoing is without prejudice to any rights MERCK may have arising under the U.S. Bankruptcy Code or other applicable law. 
  

	3.4	Exclusive Option for Non-MAP Collaboration Targets 

  

	3.4.1 	Option for Non-MAP Collaboration Targets. AVEO hereby grants to MERCK an exclusive Option to obtain an exclusive license (even as to AVEO) pursuant
to Section 3.1.1, and a non-exclusive license pursuant to Sections 3.1.2 and 3.1.3, for up to [**] Non-MAP Nominated Targets at any one time, pursuant to and subject to the provisions of this Section 3.4.1 and Section 3.4.2.

  

	3.4.2 	Procedure for Potential Collaboration Targets.  

  

	 	(a)	Disclosure of AVEO Genetic Screen Data. During the Research Program Term, AVEO shall provide to MERCK in writing the AVEO Genetic Screen Data as set forth
in this Section 3.4.2. AVEO shall inform MERCK in writing when AVEO Genetic Screen Data is available. MERCK shall, within [**] days of receiving such written notice submit to the Outside Neutral a true and complete list of MERCK Active
Programs, and shall then notify AVEO that AVEO may send the applicable AVEO Genetic Screen Data to MERCK. In no event shall the information provided by MERCK to the Outside Neutral be provided to AVEO except pursuant to Section 3.4.3 or any
Third Party unless there is a subsequent dispute over whether MERCK has complied with the provisions of this Section 3.4 relating to the existence of a MERCK Active Program. 

  

	 	(b)	 MERCK Microarray Data; Collaborative Review and Analysis. In accordance with the Research Plan, MERCK shall perform array-based
experiments on the full set of [**] arising from each of the screens and shall provide copies of all data generated in such experiments (“MERCK Microarray Data”) to AVEO. AVEO and MERCK shall collaboratively review and analyze the
AVEO Genetic Screen Data and the MERCK Microarray Data in order to better identify high quality Potential Collaboration Targets. From time-to-time, at MERCK’s sole discretion, MERCK will prioritize Potential Collaboration Targets. In so
prioritizing, MERCK may apply its own proprietary information and

  

 -21- 

	 	 
technology. For purposes of clarity, MERCK shall have no obligation to disclose to AVEO such proprietary data, technology or other information applied by MERCK. During the Research Program Term,
AVEO shall perform activities and allocate resources under the Research Plan in accordance with the prioritization communicated by MERCK to AVEO from time to time. AVEO may use the MERCK Microarray Data solely (i) in the performance of
activities specifically set forth in the Research Plan, and/or (ii) in connection with research and development of AVEO Targets, Additional Biological Targets and/or Additional Dual Targets, provided, however, that AVEO will not
willfully use MERCK Microarray Data to direct research into the discovery or identification of additional targets in the same pathway as any Potential Collaboration Target, Non-MAP Collaboration Target or Discovery Target unless such target is an
AVEO Target, an Additional Biological Target or an Additional Dual Target. 

  

	 	(c)	Nominated Targets. At any time during the Research Program Term, MERCK may, upon written notice to AVEO, designate any Potential Collaboration Target as a
“Nominated Target”, and upon any such designation, the remaining terms of this Section 3.4.2 shall apply. In such written notice, MERCK shall indicate whether MERCK had a MERCK Active Program for such designated Potential
Collaboration Target at the time that MERCK received the AVEO Genetic Screen Data for such Potential Collaboration Target pursuant to Section 3.4.2(a) above. If MERCK indicates in such notice that MERCK did not have a MERCK Active Program for a
Nominated Target at such time, such Nominated Target will be referred to herein as a “Non-MAP Nominated Target”. If MERCK indicates in such notice that MERCK had a MERCK Active Program for a Nominated Target at such time, such
Nominated Target will be referred to herein as a “MAP Nominated Target”. AVEO may, at its discretion, submit an inquiry to the Outside Neutral pursuant to Section 3.4.3 in order to verify any such designation by MERCK.

 Each Potential Collaboration Target that MERCK elects not to designate as a “Nominated Target” shall
remain subject to the rights of MERCK under this Section 3.4.2(c) until the termination of the Research Program Term, at which time all rights under the AVEO Know-How and AVEO Patent Rights relating to such Potential Collaboration Targets shall
revert to AVEO in accordance with Sections 2.8.3 or 2.8.4, as applicable. 
  

	 	(d)	Non-MAP Nominated Targets. 

  

	 	(i)	 Non-MAP Target Package Plan. Promptly following the designation by MERCK of a Non-MAP Nominated Target, the Committee shall meet and, in
accordance with Section 2.4.1, shall determine (A) a research plan for developing a Target Package for such Non-MAP Nominated Target, (B) any changes to the data required for completion of such Target Package as set forth in Schedule
1.84, and (C) the amount of time estimated to complete the package, provided that such time shall be no longer than [**] months from the date of the Committee’s decision to adopt such package plan (unless otherwise extended by a
written decision of the Committee), and provided further that, in the event that the Committee fails to decide to adopt such package plan within [**] months after the date of MERCK’s

  

 -22- 

	 	 
designation of such Non-MAP Nominated Target pursuant to Section 3.4.2(c) above (other than as a result of MERCK’s election), then such [**] month period shall automatically be deemed
to begin as of the expiration of such [**] month period (collectively, the “Non-MAP Target Package Plan”). During the ongoing effort to complete such Target Package, AVEO and MERCK shall collaborate exclusively with each other with
respect to such Non-MAP Nominated Target. If, with respect to any Non-MAP Nominated Target, AVEO fails to complete all activities as provided in the Non-MAP Target Package Plan and to deliver all such data and information required thereby to MERCK
within the timeframe required above (or, if applicable, as extended by a written decision of the Committee), then: (x) MERCK shall be permitted to use the data generated by AVEO in the course of preparing such incomplete Non-MAP Target Package
for Internal Research Purposes in the Field, and (y) AVEO may not use the MERCK Microarray Data received from MERCK relating to such Non-MAP Nominated Target for any purpose. 

  

	 	(ii)	Update to Outside Neutral. Upon the Committee’s approval of a Non-MAP Target Package Plan for a Non-MAP Nominated Target, Merck shall, within [**] days
thereafter (or, if applicable, as extended by the Parties in writing), submit to the Outside Neutral a true and complete updated list of MERCK Active Programs as of the date that the Committee approved such Non-MAP Target Package Plan. If a Non-MAP
Nominated Target has become, as of the Committee’s approval of the Non-MAP Target Package Plan for such Nominated Target, the subject of a MERCK Active Program that MERCK did not initiate based on or as a direct result of any data or
information received from AVEO pursuant to this Agreement, then MERCK shall notify AVEO in writing of such change. Upon AVEO’s receipt of such notice, such Nominated Target shall no longer be a Non-MAP Nominated Target, and shall thereafter be
deemed to be a “MAP Nominated Target” that is subject to the terms and conditions of Section 3.4.2(e); provided, however, that AVEO may, at its discretion, submit an inquiry to the Outside Neutral pursuant to
Section 3.4.3 in order to verify any such change in designation by MERCK. In no event shall the information provided by MERCK to the Outside Neutral be provided to AVEO except pursuant to Section 3.4.3 or any Third Party unless there is a
subsequent dispute over whether MERCK has complied with the provisions of Section 3.4.3 relating to the existence of a MERCK Active Program. 

  

	 	(iii)	 MERCK Option For Non-MAP Nominated Targets. Upon completion of the Target Package for a Non-MAP Nominated Target, AVEO shall deliver such Target
Package to MERCK. MERCK shall have [**] days from its receipt of such Target Package (or, if applicable, as extended by the Parties in writing) to notify AVEO in writing whether it is exercising its Option relating to such Non-MAP Nominated Target.
If MERCK exercises its Option relating to such Non-MAP Nominated Target, then such Target shall become a Non-MAP Collaboration Target

  

 -23- 

	 	 
and MERCK shall pay the milestone set forth in Section 5.3.1(1)(a). If MERCK fails to exercise its Option relating to such Non-MAP Nominated Target within the applicable [**]-day period (or,
if applicable, as extended by the Parties in writing), then such Non-MAP Nominated Target shall be a Retained Target pursuant to Section 3.1.7. In such an event, (i) MERCK shall be permitted to use the data contained in the Target Package
for Internal Research Purposes, but for no other purpose, and (ii) except as set forth below in this Section 3.4.2(d)(iii), for [**] months after MERCK receives the Target Package for such Non-MAP Nominated Target, MERCK shall not
undertake chemistry or high throughput screening specifically for the purpose of identifying modulators of such Non-MAP Nominated Target unless the relevant information contained in the Target Package is publicly disclosed through no fault of MERCK.

 Notwithstanding the foregoing, with respect to any Non-MAP Nominated Target that becomes a Retained Target
as a result of MERCK’s failure to exercise its Option pursuant to this Section 3.4.2(d)(iii), and with respect to which AVEO has not (A) encumbered or entered into discussions or negotiations with any third party regarding the
licensing or exploitation of AVEO Information and Inventions or AVEO Know-How related to such Retained Target, or (B) allocated significant resources to the research or development of such Retained Target (each, an “Available Retained
Target”), MERCK may, by written notice to AVEO at any time during the Option Period, exercise its Option to designate such Available Retained Target as a Non-MAP Collaboration Target as if such Retained Target were a Non-MAP Nominated
Target hereunder. 
  

	 	(e)	Research Collaboration for MAP Nominated Targets. 

  

	 	(i)	MAP Target Research Plan. MERCK and AVEO may collaborate with respect to each MAP Nominated Target, on a Target-by-Target basis, as set forth in this
Section 3.4.2(e). Following MERCK’s designation of a MAP Nominated Target, the Committee shall meet to develop, in accordance with Section 2.4.1, a research plan relating to such MAP Nominated Target including the total number of AVEO
FTEs and the responsibilities thereof (the “MAP Target Research Plan”). Each MAP Target Research Plan approved by the Committee shall be deemed to be part of the Research Plan, and shall be attached as a separate schedule thereto.
Upon payment of the MAP Technology Access Fee set forth in Section 3.4.2(e)(ii)(A) below with respect to a MAP Nominated Target, such MAP Nominated Target shall be deemed to be a “MAP Collaboration Target” for all purposes
hereunder. 

  

 -24- 

	 	(ii)	Financial Terms. 

  

	 	(A)	Technology Access Fee. Within thirty (30) days after the Committee’s approval of the MAP Target Research Plan for each MAP Nominated Target, MERCK
shall pay AVEO a technology access fee of [**] Dollars (US $[**]) (the “MAP Technology Access Fee”). 

  

	 	(B)	Research Funding. In consideration for AVEO’s research and development activities pursuant to each MAP Target Research Plan that is approved by the
Committee in accordance with Section 2.4.1, MERCK shall pay AVEO at the rate of [**] Dollars (US$[**]) per AVEO FTE. 

  

	 	(C)	Milestones. For each MAP Collaboration Target, MERCK shall also pay AVEO milestone payments in accordance with Section 5.3.1(1)(c) through 5.3.1(1)(f) and
5.3.1(2) as if the MAP Collaboration Target were a Non-MAP Collaboration Target, provided that, such milestone payments shall begin upon the achievement of the milestone set forth in Section 5.3.1(1)(c), inclusive of such milestone, and
shall in all cases be reduced to an amount that is equal to [**] percent ([**]%) of the amounts set forth in Section 5.3.1 for each milestone therein. 

  

	 	(D)	No Royalties. Notwithstanding the provisions of Section 5.4, MERCK shall have no obligation to pay any royalties to AVEO under this Agreement with respect
to MAP Nominated Targets or MAP Collaboration Targets, including the rights and licenses granted under Section 3.1.4. 

  

	 	(f)	Target Packages Submitted Prior To Restatement Effective Date. The Parties acknowledge and agree that all Target Packages submitted by AVEO to MERCK prior
to the Restatement Effective Date are hereby deemed to be complete as of their respective dates of delivery, and nothing in this Agreement shall require any additional work to be performed by AVEO with respect to such Target Packages.
Notwithstanding the terms and conditions of Section 3.4.2, all of such Target Packages shall be subject to the [**] day Option period set forth in Section 3.4.2(d)(iii) above, provided, however, that (i) the [**] day
Option period for each such Target Package shall be deemed to have begun (or begin, as applicable) (A) with respect to any Target Package received by MERCK in calendar year 2004, upon receipt of such Target Package by MERCK, and (B) with
respect to any Target Package received MERCK in calendar year 2005, [**] days after MERCK’s receipt of such Target Package (and, in each case, nothing herein shall extend such period unless otherwise agreed to by the Parties in writing),
(ii) all such Targets with respect to which MERCK has not or does not exercise its Option within the applicable Option period shall be deemed to be Expired Targets (regardless of whether such Targets were the subject of a MERCK Active Program
as of the submission of the relevant Target Package), (iii) any such Targets with respect to which MERCK exercises its Option within the applicable Option period and which were not at the time of submission of the relevant Target Package the
subject of a Merck Active Program, shall be deemed to be Non-MAP Collaboration Targets under this Agreement, and (iv) any such Targets with respect to which Merck exercises its Option within the applicable Option period and which were at the
time of submission of the relevant Target Package the subject of a Merck Active Program, shall be deemed to be MAP Nominated Targets under this Agreement and subject to the terms and conditions of Section 3.4.2(e) hereof.

  

 -25- 

	3.4.3 	Inquiries to Outside Neutral. In the event that AVEO in good faith believes that MERCK has improperly designated a Nominated Target based on
whether a MERCK Active Program existed, AVEO shall notify MERCK in writing of such belief, and if AVEO is not satisfied with MERCK’s explanation, then AVEO may inquire of the Outside Neutral whether MERCK has previously identified a particular
Nominated Target as being the subject of a MERCK Active Program prior to the Relevant Non-MAP Dates and the Relevant MAP Date, as applicable. All communications between AVEO and the Outside Neutral shall be in writing, with a copy to MERCK. In no
event shall the Outside Neutral provide any information to AVEO except in response to a specific written inquiry relating to a specified Nominated Target. In the event of a dispute between the Parties regarding MERCK’s designation of a
Nominated Target as either a MAP Nominated Target or a Non-MAP Nominated Target, AVEO and MERCK shall cooperate in order to resolve such dispute in accordance with Section 9.6. 

  

	3.4.4 	Substitution of Non-MAP Collaboration Targets. At any time during the Option Period (as defined in Section 3.4.5 below), MERCK may, in its sole
discretion, but subject to the limitations set forth in Sections 3.4.2, and 3.4.1: (a) inform AVEO in writing that it wishes to replace a Non-MAP Collaboration Target for which MERCK has previously exercised its Option with a different
Potential Collaboration Target that is not an AVEO Target, or (b) select an additional Non-MAP Collaboration Target to replace a Non-MAP Collaboration Target that has qualified as a Discovery Target. For purposes of clarity, MERCK’s rights
under this Section 3.4.4 shall not apply to any AVEO Target. Upon providing such written notice, and upon payment of the milestone set forth in 5.3.1(1)(a), MERCK shall have the licenses to such new Non-MAP Collaboration Target set forth in
Sections 3.1.1, 3.1.2, and 3.1.3. Rights to a Non-MAP Collaboration Target that is replaced pursuant to Section 3.4.4(a) (the “Replaced Target”) shall revert in full to AVEO, and MERCK shall provide to AVEO a MERCK Non-MAP
Collaboration Target Package relating to such Non-MAP Collaboration Target as provided in Section 3.5(b); provided, however, that MERCK shall retain the right to use Joint Information and Inventions and MERCK Information and
Inventions for all purposes outside the Field, and relating to such Replaced Target for Internal Research Purposes in the Field. 

  

	3.4.5 	 Duration of MERCK’s Option Rights. Unless MERCK terminates the Research Program prior to the end of the Initial Research
Program Term (in which case, the Option Period shall be deemed immediately terminated), the period of time during which AVEO shall be obligated to present Target Packages to MERCK subject to and in accordance with Section 3.4.2, shall continue
for the duration of the Research Program Term, and for a period of [**] months thereafter (the “Option Period”). Notwithstanding anything to the contrary in this Agreement, (i) AVEO shall have no obligation to conduct
any research

  

 -26- 

	 	 
other than pursuant to the Research Plan (including pursuant to any Non-MAP Target Package Plan or MAP Target Research Plan) and during the Research Program Term, (ii) at the end of the
Option Period, except as otherwise set forth in this Agreement (including but not limited to MERCK’s right to use AVEO Information and Inventions or AVEO Know-How for Internal Research Purposes), (A) all rights under MERCK Know-How and
MERCK Patent Rights relating to Expired Targets (as defined below) shall in each case (to the extent such rights have not already reverted to MERCK) immediately and unconditionally revert to MERCK, and (B) all rights under AVEO Know-How and
AVEO Patent Rights relating to Expired Targets (as defined below) shall in each case (to the extent such rights have not already reverted to AVEO) immediately and unconditionally revert to AVEO. For purposes of clarity, nothing contained in this
Section 3.4.5 shall be deemed: (A) to limit or prevent MERCK in any way from pursuing any Potential Collaboration Target using intellectual property other than: (i) AVEO Know-How and AVEO Patent Rights, or (ii) any other
intellectual property Controlled by AVEO, or (B) to provide MERCK with any right to exercise any Option, with respect to any Non-MAP Nominated Targets, after the expiration of the [**] period set forth in Section 3.4.2(d)(iii) with respect
thereto (or, if applicable, as extended by the Parties in writing), or with respect to any Available Retained Target, after the expiration of the Option Period (or, if applicable, as extended by the Parties in writing). As used in this Agreement,
the term “Expired Targets” shall mean all Potential Collaboration Targets (including, without limitation, Non-MAP Nominated Targets and MAP Nominated Targets) that are not, in each case, as of the expiration of the Option Period,
either Non-MAP Collaboration Targets, MAP Collaboration Targets, or Discovery Targets. 

  

	3.5	Research, Development and Commercialization 

  

	 	(a)	Collaboration Models. AVEO shall use Commercially Reasonable Efforts to develop the Collaboration Models pursuant to the Research Plan. 

 

	 	(b)	Non-MAP Collaboration Targets. MERCK shall use Commercially Reasonable Efforts, at its own expense, to conduct pre-clinical research on Non-MAP Collaboration
Targets in order to advance the research relating to such Non-MAP Collaboration Targets such that they qualify as Discovery Targets, and shall notify AVEO in writing promptly upon qualification as Discovery Targets. If MERCK fails to exercise
reasonable diligence in pursuing research regarding a Non-MAP Collaboration Target such that it qualifies as a Discovery Target within a reasonable period as determined by the Committee (but in any case within [**] months after such Target is first
designated as a Non-MAP Collaboration Target), or if such Non-MAP Collaboration Target otherwise reverts to AVEO pursuant to Section 3.1.7(ii)(b) or (d), all AVEO Patent Rights and AVEO Know-How relating to such Non-MAP Collaboration Target
shall revert to AVEO, and MERCK shall, upon AVEO’s request, provide the MERCK Non-MAP Collaboration Target Data Package for such Non-MAP Collaboration Target to AVEO, and AVEO shall be permitted to use and otherwise exploit the information
contained in such MERCK Non-MAP Collaboration Target Data Package for research and commercialization purposes; provided, however, that MERCK shall retain the right to use Joint Information and Inventions and MERCK Information and
Inventions for all purposes outside the Field, and relating to such Non-MAP Collaboration Target for Internal Research Purposes in the Field. 

  

 -27- 

	 	(c)	Discovery Targets. MERCK shall use Commercially Reasonable Efforts, at its own expense, to conduct pre-clinical research on Discovery Targets in order to
identify Development Candidates Directed at such Discovery Target. If MERCK fails to identify Development Candidates Directed at such Discovery Target within a reasonable period as determined by the Committee, or if rights to such Discovery Target
otherwise revert to AVEO pursuant to Section 3.1.7(ii)(b) or (d), all AVEO Patent Rights and AVEO Know-How relating to such Discovery Target shall revert to AVEO, and MERCK shall, upon AVEO’s request, provide the MERCK Discovery Target
Data Package for such Discovery Target to AVEO, and AVEO shall be permitted to use and otherwise exploit the information contained in such MERCK Discovery Target Data Package for research and commercialization purposes; provided,
however, that MERCK shall retain the right to use Joint Information and Inventions and MERCK Information and Inventions for all purposes outside the Field, and related to such Discovery Target for Internal Research Purposes in the Field. In
the event that such Discovery Target becomes an AVEO Target pursuant to this Section, AVEO and MERCK shall, at AVEO’s request made within [**] days of AVEO’s receipt of the MERCK Discovery Target Data Package, negotiate in good faith
concerning the license to AVEO of compounds discovered or developed by MERCK related to such Discovery Target that MERCK, in its sole discretion, elects to out-license, upon terms to be negotiated in good faith by the Parties and reflected in a
separate agreement. For the avoidance of doubt, MERCK shall be under no obligation to enter any agreement with AVEO, to provide AVEO with any particular terms in comparison to any other potential licensee, or to give AVEO preference over any other
potential licensee. 

  

	 	(d)	Products. MERCK shall use Commercially Reasonable Efforts, at its own expense, to develop and commercialize each Product on a commercially reasonable basis in
such countries in the Territory where in MERCK’s opinion it is commercially viable to do so. 

  

	3.6	Excused Performance 

 In addition to the provisions of Article 6 hereof, the obligations of MERCK with respect to any Product under Section 3.5 are expressly conditioned upon the continuing absence of any adverse condition or event relating to the safety or
efficacy of the Product, and the obligation of MERCK to develop or market any such Product shall be delayed or suspended so long as in MERCK’s opinion any such condition or event exists. 
  

 -28- 

	3.7	Additional Targets 

  

	3.7.1 	Additional Biological Targets. Additional Biological Targets shall not be deemed to be Potential Collaboration Targets unless (i) MERCK
notifies AVEO that it desires to nominate an Additional Biological Target as a Non-MAP Nominated Target, and (ii) AVEO, in its sole discretion, expressly agrees in writing that such Additional Biological Target shall be deemed to be a Potential
Collaboration Target. 

  

	3.7.2 	Additional Model Targets. AVEO may, in its sole discretion, communicate to MERCK that it desires to provide data to MERCK regarding an Additional
Model Target. In such case, MERCK and AVEO may negotiate the terms upon which AVEO would be willing to disclose and MERCK would be willing to accept such data. AVEO shall have no obligation to disclose any data or otherwise grant any rights to MERCK
with respect to any Additional Model Target, and MERCK shall have no obligation to accept or receive any such data or rights, unless and until AVEO and MERCK enter into a mutually acceptable written agreement with respect thereto.

  

	3.7.3 	Additional Dual Targets. With respect to each Non-MAP Collaboration Target that is an Additional Dual Target, a Collaboration Compound shall
exclude the rights set forth in Section 1.8(c)(ii) unless (i) MERCK notifies AVEO that it desires to include within the definition of Collaboration Compounds for such Target Biologicals that are intended to and actually inhibit or
modulate the activity of such Target, and (ii) AVEO, in its sole discretion, expressly agrees in writing pursuant to this Section 3.7.3 that Biologicals that are intended to and actually inhibit or modulate the activity of such Target
shall be included within the definition of Collaboration Compound specifically for such Target. 

  

	4.	CONFIDENTIALITY AND PUBLICATION 

  

	4.1	Nondisclosure Obligation 

 All Information disclosed by one Party to the other Party hereunder shall be maintained in confidence by the receiving Party and shall not be disclosed to a Third Party or used for any purpose except as set forth herein without the prior
written consent of the disclosing Party, except to the extent that such Information: 
  

	 	(a)	is known by receiving Party at the time of its receipt, and not through a prior disclosure by the disclosing Party, as documented by the receiving Party’s business
records; 

  

	 	(b)	is properly in the public domain through no fault of the receiving Party; 

  

	 	(c)	is subsequently disclosed to the receiving Party by a Third Party who may lawfully do so and is not under an obligation of confidentiality to the disclosing Party;

  

	 	(d)	is developed by the receiving Party independently of Information received from the disclosing Party, as documented by the receiving Party’s business records;

  

	 	(e)	is disclosed to governmental or other regulatory agencies in order to obtain patents or to gain or maintain approval to conduct clinical trials or to market Product,
but such disclosure may be only to the extent reasonably necessary to obtain patents or authorizations; 

  

 -29- 

	 	(f)	is deemed necessary (i) by MERCK to be disclosed to Related Parties, agents, consultants, and/or other Third Parties for development (including regulatory
approvals), manufacturing and/or marketing of a Product (or for such parties to determine their interest in performing such activities) in accordance with this Agreement, or (ii) by AVEO to be disclosed to such Third Parties that are permitted
pursuant to Section 2.2 to perform its Research Program activities, in either case on the condition that such Third Parties agree to be bound by the confidentiality and non-use obligations contained this Agreement, provided the term of
confidentiality for such Third Parties shall be no less than seven (7) years; or 

 Any combination of
features or disclosures shall not be deemed to fall within the foregoing exclusions merely because individual features are published or available to the general public or in the rightful possession of the receiving Party, unless the combination
itself and principle of operation are published or available to the general public or in the rightful possession of the receiving party. For purposes of clarity, a scientific association between a Target with a disease or therapeutic area shall not
be deemed to fall within the foregoing exclusions merely because such Target (and/or the gene sequence of such Target) is published or available to the general public. 
 If a Party is required by judicial or administrative process to disclose Information that is subject to the non-disclosure provisions of this Section 4.1 or Section 4.2, such Party shall
promptly inform the other Party of the disclosure that is being sought in order to provide the other Party an opportunity to challenge or limit the disclosure obligations. Information that is disclosed by judicial or administrative process shall
remain otherwise subject to the confidentiality and non-use provisions of this Section 4.1 and Section 4.2, and the Party disclosing Information pursuant to law or court order shall take all steps reasonably necessary, including without
limitation obtaining an order of confidentiality, to ensure the continued confidential treatment of such Information. 
  

	4.2	AVEO Know-How 

 AVEO agrees to keep all AVEO Know-How relating to Non-MAP Collaboration Targets, Discovery Targets, Collaboration Compounds and/or Products confidential subject to exception (b) in Section 4.1 above; provided,
however, AVEO shall be free to disclose AVEO Know-How (i) outside of the Field for any purpose, including but not limited to the purpose of researching, developing and commercializing Biologicals, (ii) in the exercise of any right
retained by AVEO or any right that reverts to AVEO, including, without limitation, any use and exploitation of the AVEO Targets, (iii) in connection with the prosecution, maintenance, enforcement or defense of any Patent Rights, (iv) in
connection with the enforcement of the terms of this Agreement, (v) as required by law or any governmental authority, or (vi) to a limited number of potential investors for purposes of any equity or debt financing, provided,
however, that AVEO shall not disclose the Research Plan or any portion thereof or the identity of any specific Potential

  

 -30- 

 
Collaboration Target, Non-MAP Collaboration Target, MAP Collaboration Target, Discovery Target, Non-MAP Nominated Target or MAP Nominated Target to such potential investors. For purposes of
clarification, AVEO shall not be prohibited from disclosing AVEO-Controlled information that is not AVEO Know-How, including but not limited to, discoveries, processes, methods, protocols, formulas, data, inventions, know-how and trade secrets,
patentable or otherwise that are necessary or useful in connection with or that claim or cover the Collaboration Models or any other method, material, tool or technology conceived or used by or on behalf of AVEO for the discovery of any target,
other than the Non-MAP Collaboration Targets, Discovery Targets, Collaboration Compounds and/or Products. 
  

	4.3	Publication 

 MERCK
and AVEO each acknowledge the other Party’s interest in publishing the results of its research in order to obtain recognition within the scientific community and to advance the state of scientific knowledge. Each Party also recognizes the
mutual interest in obtaining valid patent protection and in protecting business interests and trade secret information. Consequently, except for disclosures permitted pursuant to Section 4.1, either Party, its employees or consultants wishing
to make a publication arising from the conduct of the Research Program shall deliver to the other Party a copy of the proposed written publication or an outline of an oral disclosure at least sixty (60) days prior to submission for publication
or presentation. The reviewing Party shall have the right (a) to propose modifications to the publication or presentation for patent reasons, trade secret reasons or business reasons, or (b) to request a reasonable delay in publication or
presentation in order to protect patentable information. If the reviewing Party requests a delay, the publishing Party shall delay submission or presentation for a period of ninety (90) days to enable patent applications protecting each
Party’s rights in such information to be filed in accordance with Article 7 below. Upon expiration of such ninety (90) days, the publishing Party shall be free to proceed with the publication or presentation. If the reviewing Party
requests modifications to the publication or presentation, the publishing Party shall edit such publication to prevent disclosure of trade secret or proprietary business information prior to submission of the publication or presentation. 

 

	4.4	Publicity/Use of Names 

 No disclosure of the existence of, or the terms of, this Agreement may be made by either Party, and no Party shall use the name, trademark, trade name or logo of the other Party or its employees in any publicity, news release or disclosure
relating to this Agreement or its subject matter, without the prior express written permission of the other Party, except as provided in Section 4.4(a), (b), (c) or (d). 
 (a) Either Party shall be permitted to disclose the existence and terms of this Agreement to the extent required, in the reasonable opinion
of such Party’s legal counsel, to comply with applicable laws, including without limitation the rules and regulations promulgated by the United States Securities and Exchange Commission or any other governmental agency. Notwithstanding the
foregoing, before disclosing this Agreement or any of the terms hereof pursuant to this Section 4.4(a), the Parties will consult with one another on the terms of this Agreement to be redacted in making any such disclosure. If a Party discloses
this Agreement or any of the terms hereof in accordance with this Section 4.4(a), such Party agrees, at its own expense, to seek confidential treatment of the portions of this Agreement or such terms, as may be reasonably requested by the other
Party. 
  

 -31- 

 (b) Either Party may also disclose the existence and terms of this Agreement to potential
acquirors, investors or lenders of such Party, as a part of their due diligence investigations, provided that such potential acquirors, investors or lenders have agreed in writing to keep the terms of this Agreement confidential and to use such
confidential information solely for the purpose permitted pursuant to this Section 4.4(b), provided, however, that AVEO shall not disclose the Research Plan or any portion thereof or the identity of any specific Potential
Collaboration Target, Nominated Target, Non-MAP Collaboration Target, MAP Collaboration Target or Discovery Target to such potential investors. Further, either Party may freely disclose any information that has been previously approved for
disclosure by the other Party. 
 (c) The Parties hereby acknowledge that, following the Effective Date, AVEO issued a press
release substantially similar to that set forth in Schedule 4.4(c). Following the Restatement Effective Date, AVEO may at its discretion issue a press release regarding this Agreement, provided that such release will be subject to MERCK’s prior
review and written approval. 
 (d) Upon the request of AVEO, AVEO and MERCK shall agree upon the text of a redacted copy of the
Agreement that AVEO shall be permitted to disclose to potential Third Party collaborators outside of the Field, on the condition that such Third Parties agree to be bound by the confidentiality and non-use obligations contained in this Agreement,
and provided the term of confidentiality for such Third Parties shall be no less than seven (7) years. 
  

	5.	PAYMENTS; ROYALTIES AND REPORTS

	  	[	**] 
		
	          (d) [**]
	  	[	**] 

  

	5.3.2 	Fast-Track HTS. Notwithstanding Section 5.3.1(1)(b) above, (a) for a period of two (2) years starting upon the Restatement Effective Date
and continuing through the Option Period, MERCK may advance the research regarding up to [**] Non-MAP Collaboration Targets per year such that they qualify as Discovery Targets without any obligation to pay the milestone payment set forth in
Section 5.3.1(1)(b), and (b) for each calendar year after the second anniversary of the Restatement Effective Date that falls wholly or partially within the Option Period, MERCK may advance the research regarding up to [**] Non-MAP
Collaboration Targets for such annual period within the Research Program Term such that they qualify as Discovery Targets without any obligation to pay the milestone payment set forth in Section 5.3.1(1)(b), provided that MERCK pays to
AVEO a fee of [**] Dollars (US$[**]) for such calendar year or portion thereof. Except as expressly set forth in the foregoing sentence, the milestone payment obligation in Section 5.3.1(1)(b) shall remain in full force and effect.

  

 -33- 

	5.3.3 	Payment of Milestones. Upon the achievement of each milestone, MERCK shall notify AVEO in writing within thirty (30) days of such achievement,
and shall make the appropriate milestone payment within thirty (30) days of such achievement. A milestone payment shall be payable only upon the initial achievement of such milestone and no amounts shall be due hereunder for subsequent or
repeated achievement of such milestone for the same Non-MAP Collaboration Target or MAP Collaboration Target, in the case of Section 5.3.1(1), or for the same Product, in the case of Section 5.3.1(2); provided, however, that,
with respect to each Additional Dual Target, a milestone payment shall be payable upon the initial achievement of such milestone for both a chemical entity and a Biological inhibitor or modulator of such Target. Upon the achievement of a particular
milestone for a Non-MAP Collaboration Target, MAP Collaboration Target or Product, as applicable, all preceding milestones for such Non-MAP Collaboration Target, MAP Collaboration Target or Product, as applicable, shall be deemed achieved to the
extent not previously achieved and shall be paid contemporaneously therewith; provided, however, that the milestones payable under Sections 5.3.1(1)(a) and (b) shall under no condition be payable for any MAP Nominated Target or
MAP Collaboration Target. 

  

	5.4	Royalties 

  

	5.4.1 	Royalties Payable By MERCK. Subject to the terms and conditions of this Agreement, MERCK shall pay to AVEO royalties, calculated on a
Product-by-Product basis, as set forth in this Section 5.4.1. 

  

	5.4.1.1 	Patent Royalties; Competitive Product. 

  

	 	(a)	Royalty Tiers. Subject to the provisions of Section 5.4.1.1(b) and (c) and Section 5.4.1.2, MERCK shall pay AVEO in an amount equal to the
following percentage of Net Sales of Products by MERCK or its Related Parties, provided the sale of the Product would infringe a Valid Patent Claim in the country of sale: 

  

	 	(i)	[**] percent ([**]%) of worldwide Net Sales in each Calendar Year up to and including [**] Dollars ($US [**]); 

  

	 	(ii)	[**] percent ([**]%) of worldwide Net Sales in each Calendar Year on the increment of Net Sales which exceed [**] Dollars ($US [**]) and up to and including [**]
Dollars ($US [**]); and 

  

	 	(iii)	[**] percent ([**]%) of worldwide Net Sales in each Calendar Year on the increment of Net Sales over [**] Dollars ($US [**]). 

  

	 	(b)	Competitive Products. If the sale of a Product would not, absent the license hereunder, infringe a Valid Patent Claim of a AVEO Patent Right in the country of
sale, then notwithstanding the provisions of Section 5.4.1.1(a) above, in countries where a Competitive Product is sold, the royalty payable by MERCK to AVEO shall be [**] percent ([**]%) of Net Sales by MERCK or its Related Parties. The Net
Sales on which such royalties are based shall not be included in calculating the royalty tiers under Section 5.4.1.1(a) above. 

  

 -34- 

	5.4.1.2 	Know-How Royalty. Notwithstanding the provisions of Section 5.4.1. above, in countries where the sale of Product by MERCK or its Related Parties would not
infringe a Valid Patent Claim, MERCK shall pay royalty rates that shall be set at [**] percent ([**]%) of the lowest applicable royalty rate determined according to 5.4.1.1., as applicable. Such royalties shall be calculated after first calculating
royalties under Section 5.4.1.1 above. 

  

	5.4.1.3 	Calculation of Royalty. Royalty tiers pursuant to 5.4.1.1 and 5.4.1.2 shall be calculated based on worldwide Net Sales of each Product, provided that the
determination of whether the royalty shall be calculated under 5.4.1.1(b) and/or 5.4.1.2 shall be determined on a country-by-country basis. Royalties on each Product at the rates set forth above shall continue on a country-by-country basis until the
expiration of the later of: (i) the last-to-expire Valid Patent Claim; or (ii) for a period of ten (10) years after First Commercial Sale of such Product in such country (the “Royalty Period”). All royalties are
subject to the following conditions: 

 (x) that only one royalty shall be due with respect to the same unit of
Product; 
 (y) that no royalties shall be due upon the sale or other transfer among MERCK or its Related Parties, but in such
cases the royalty shall be due and calculated upon MERCK’s or its Related Party’s Net Sales to the first independent Third Party; and 
 (z) no royalties shall accrue on the disposition of Product in reasonable quantities by MERCK or its Related Parties as samples (promotion or otherwise) or as donations (for example, to non-profit
institutions or government agencies for a non-commercial purpose). 
  

	5.4.2 	Change in Sales Practices. The Parties acknowledge that during the term of this Agreement, MERCK’s sales practices for the marketing and distribution
of Product may change to the extent to which the calculation of the payment for royalties on Net Sales may become impractical or even impossible. In such event the Parties agree to meet and discuss in good faith new ways of compensating AVEO to the
extent currently contemplated under Section 5.4.1; provided, however if the Parties cannot agree on new ways of compensating AVEO, the terms of this Agreement shall remain in full force and effect. 

  

	5.4.3 	Royalties for Bulk Product. In those cases where MERCK sells bulk Product that is not in a finished, packaged form to a Third Party, the royalty
obligations of Section 5.4.1 shall be applicable to the bulk Product; provided, however, that if MERCK obtains additional compensation relating to the use or commercialization of such bulk Product, then the Parties agree that
there shall be additional compensation to AVEO reflecting the value of such additional compensation in an amount to be mutually agreed upon by the Parties. 

  

	5.4.4 	Compulsory Licenses. If a compulsory license is granted to a Third Party with respect to Product in any country in the Territory with a royalty
rate lower than the royalty rate provided by Section 5.4.1, then the royalty rate to be paid by MERCK on Net Sales in that country under Section 5.4.1 shall be reduced to the rate paid by the compulsory licensee. 

 

 -35- 

	5.4.5 	Third Party Licenses. In the event that one or more patent licenses from other Third Parties are required by MERCK or its Related Parties in order to
make, have made, use, offer to sell, sell and/or import any Collaboration Compound(s) or Product(s) (“Third Party Patent Licenses”), and, in the absence of such license, the use by MERCK of the AVEO Patent Rights, AVEO
Know-How or AVEO Information and Inventions would infringe such Third Party patents, [**] percent ([**]%) of the consideration actually paid under such Third Party Patent Licenses by MERCK or its Related Parties for sale of such Collaboration
Compound or Product in a country for a Calendar Quarter shall be creditable against the royalty payments due AVEO by MERCK with respect to the sale of such Collaboration Compound(s) or Product(s) in such country; provided, however,
that in no event shall the royalties owed by MERCK to AVEO for such Calendar Quarter in such country be reduced, as a result of the reduction set forth in this section and the set-offs provided in Sections 7.1(d) and 7.3(b), by more than [**]
percent ([**]%) of the applicable royalty rate set forth in Section 5.4.1.1; and any amounts not able to be reduced due to the immediately foregoing limitation shall be carried forward to future Calendar Quarters for crediting against future
royalties in such country. For purposes of clarity, the foregoing credit shall not apply to claims of Third Party Patent Rights which relate to composition of matter of any Collaboration Compound or Product, or to the formulation, manufacturing or
delivery thereof. 

  

	5.4.6 	Reports; Payment of Royalty. During the term of the Agreement following the First Commercial Sale of a Product, MERCK shall furnish to AVEO a
quarterly written report for the Calendar Quarter showing the Net Sales of all Products subject to royalty payments sold by MERCK and its Related Parties in the Territory during the reporting period and the royalties payable under this Agreement.
Reports shall be due on the sixtieth (60) day following the close of each Calendar Quarter. Royalties shown to have accrued by each royalty report shall be due and payable on the date such royalty report is due. MERCK shall keep complete and
accurate records in sufficient detail to enable the royalties payable hereunder to be determined. 

  

	5.5	Audits 

  

	 	(a)	Upon the written request of AVEO and not more than once in each Calendar Year, MERCK shall permit an independent certified public accounting firm of nationally
recognized standing selected by AVEO and reasonably acceptable to MERCK, at AVEO’s expense, to have access during normal business hours to such of the records of MERCK as may be reasonably necessary to verify the accuracy of the royalty reports
hereunder for any year ending not more than twenty-four (24) months prior to the date of such request. The accounting firm shall disclose to AVEO only whether the royalty reports are correct or incorrect and the specific details concerning any
discrepancies. No other information shall be provided to AVEO. 

  

 -36- 

	 	(b)	If such accounting firm correctly identifies a discrepancy made during such period, the appropriate Party shall pay the other Party the amount of the discrepancy within
thirty (30) days of the date AVEO delivers to MERCK such accounting firm’s written report so correctly concluding, or as otherwise agreed upon by the Parties. The fees charged by such accounting firm shall be paid by AVEO unless the
underpayment exceeded the greater of [**] thousand dollars ($[**]) and five percent (5%) of the royalty owed by MERCK to AVEO for such Calendar Year, in which case, MERCK shall pay to AVEO the fees charged by such accounting firm.

  

	 	(c)	MERCK shall include in each sublicense granted by it pursuant to this Agreement a provision requiring the sublicensee to make reports to MERCK, to keep and maintain
records of sales made pursuant to such sublicense and to grant access to such records by AVEO’s independent accountant to the same extent required of MERCK under this Agreement. Upon the expiration of twenty-four (24) months following the
end of any year, the calculation of royalties payable with respect to such year shall be binding and conclusive upon AVEO, and MERCK and its Related Parties shall be released from any liability or accountability with respect to royalties for such
year. 

  

	 	(d)	AVEO shall treat all financial information subject to review under this Section 5.5 or under any sublicense agreement in accordance with the confidentiality and
non-use provisions of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with MERCK and/or its Related Parties obligating it to retain all such information in confidence pursuant to such
confidentiality agreement. 

  

	5.6	Payment Exchange Rate 

 All payments to be made by MERCK to AVEO under this Agreement shall be made in United States dollars and may be paid by check made to the order of AVEO or bank wire transfer in immediately available funds to such bank account in the United
States designated in writing by AVEO from time to time. In the case of sales outside the United States, the rate of exchange to be used in computing the amount of currency equivalent in United States dollars due AVEO shall be made at the monthly
rate of exchange utilized by MERCK in its worldwide accounting system, prevailing on the third to the last business day of the month prior to the month in which such sales are recorded by MERCK. 
  

	5.7	Income Tax Withholding 

 If laws, rules or regulations require withholding of income taxes or other taxes imposed upon payments set forth in this Article 5, MERCK shall make such withholding payments as required and subtract such withholding payments from the
payments set forth in this Article 5. MERCK shall submit appropriate proof of payment of the withholding taxes to AVEO within a reasonable period of time.

 MERCK agrees to defend AVEO and its Affiliates at its cost and expense, and will indemnify and hold AVEO and its Affiliates and their respective directors, officers, employees and agents (the “AVEO Indemnified Parties”)
harmless from and against any losses, costs, damages, fees or expenses arising out of any Third Party claim relating to personal injury or death from the development, manufacture, use, sale or other disposition of the Product(s) by MERCK and/or
its Related Parties or collaborators. In the event of any such claim against the AVEO Indemnified Parties by any Third Party, AVEO shall promptly notify MERCK in writing of the claim and MERCK shall manage and control, at its sole expense, the

	7.	PATENT PROVISIONS 

  

	7.1	Filing, Prosecution and Maintenance of Patents 

  

	 	(a)	AVEO Patent Rights. AVEO shall have the first right and option to file and prosecute any patent applications and maintain any patents included in the AVEO Patent
Rights. AVEO shall provide MERCK with an opportunity to review and comment on any papers to be filed in any patent office prior to their submission relating to each Non-MAP Collaboration Target from and after the exercise by MERCK of its Option to
such Non-MAP Collaboration Target. AVEO shall promptly give notice to MERCK of the allowance, grant, lapse, revocation, surrender, invalidation or abandonment of any AVEO Patent Rights licensed to MERCK for which AVEO is responsible for the filing,
prosecution and maintenance. If AVEO declines to file and prosecute any such patent application or maintain any such patents covering any AVEO Patent Rights licensed to MERCK under this Agreement, it shall give MERCK reasonable notice to this effect
and thereafter MERCK may, upon written notice to AVEO, file and prosecute such patent applications and maintain such patents in AVEO’s name. For patents and patent applications within the AVEO Patent Rights licensed to MERCK but not owned by
AVEO, AVEO will use its reasonable efforts to arrange the same rights for MERCK with the owners of such patents and patent applications. 

  

 -39- 

	 	(b)	Joint Information and Inventions. MERCK shall have the first right and option to file and prosecute patent applications included in Joint Patent Rights, and
maintain any patents included in Joint Patent Rights, at MERCK’s expense. MERCK shall provide AVEO with an opportunity to review and comment on any papers to be filed in any patent office prior to their submission relating to each Non-MAP
Collaboration Target. MERCK shall promptly give notice to AVEO of the allowance, grant, lapse, revocation, surrender, invalidation or abandonment of any Joint Patent Rights for which MERCK is responsible for the filing, prosecution and maintenance.
If MERCK declines to file and prosecute any such patent application or maintain any such patents covering any Joint Patent Rights, it shall give AVEO reasonable notice to this effect and thereafter AVEO may, upon written notice to MERCK, file and
prosecute such patent applications and maintain such patents in MERCK’s and AVEO’s names. 

  

	 	(c)	MERCK Information and Inventions. MERCK shall have the exclusive right and option to file and prosecute any patent applications and to maintain any patents
covering MERCK Information and Inventions, at MERCK’s expense. 

  

	 	(d)	Expenses. All costs associated with filing, prosecuting and maintaining the AVEO Patent Rights, including the costs of any interference, opposition,
reexamination or reissue proceeding, shall by borne by AVEO. If AVEO declines to file, prosecute and/or maintain any of the AVEO Patent Rights and MERCK assumes such responsibilities, the costs associated with such patents or patent applications
shall be [**] by MERCK and AVEO; provided that MERCK shall pay all such costs and shall recoup AVEO’s [**] percent ([**]%) share as a setoff against royalties or milestones until AVEO’s share has been fully paid, provided further
that the royalty payment to AVEO in any Calendar Quarter shall not, as a result of the setoffs provided in this section and in Section 7.3(b) and the reduction set forth in Section 5.4.5, be reduced by more than [**] percent ([**]%) of
the amount otherwise owed to AVEO; and any amounts not able to be reduced due to the immediately foregoing limitation shall be carried forward to future Calendar Quarters for setoff against future royalties. 

  

	7.2	Interference, Opposition, Reexamination and Reissue 

  

	 	(a)	AVEO shall, within ten (10) days of learning of such event, inform MERCK of any request for, or filing or declaration of, any interference, opposition, or
reexamination relating to AVEO Patent Rights. MERCK and AVEO shall thereafter consult and cooperate fully to determine a course of action with respect to any such proceeding. MERCK shall have the right to review and approve any submission to be made
in connection with such proceeding. 

  

 -40- 

	 	(b)	AVEO shall not initiate any reexamination, interference or reissue proceeding relating to AVEO Patent Rights without the prior written consent to MERCK, which consent
shall not be unreasonably withheld. 

  

	 	(c)	In connection with any interference, opposition, reissue, or reexamination proceeding relating to AVEO Patent Rights, MERCK and AVEO will cooperate fully and will
provide each other with any information or assistance that either may reasonably request. AVEO shall keep MERCK informed of developments in any such action or proceeding, including, to the extent permissible by law, consultation and approval of any
settlement, the status of any settlement negotiations and the terms of any offer related thereto. 

  

	7.3	Enforcement and Defense 

  

	 	(a)	AVEO shall give MERCK notice of either (i) any infringement of AVEO Patent Rights, or (ii) any misappropriation or misuse of AVEO Know-How, that may come to
AVEO’s attention. MERCK and AVEO shall thereafter consult and cooperate fully to determine a course of action, including but not limited to the commencement of legal action by either or both MERCK and AVEO, to terminate any infringement of AVEO
Patent Rights or any misappropriation or misuse of AVEO Know-How. However, AVEO, upon notice to MERCK, shall have the first right to initiate and prosecute such legal action at its own expense and in the name of AVEO and MERCK, or to control the
defense of any declaratory judgment action relating to AVEO Patent Rights or AVEO Know-How. AVEO shall promptly inform MERCK if it elects not to exercise such first right and MERCK shall thereafter have the right to either initiate and prosecute
such action or to control the defense of such declaratory judgment action in the name of MERCK and, if necessary, AVEO. Each Party shall have the right to be represented by counsel of its own choice. 

  

	 	(b)	In the event that AVEO elects not to initiate and prosecute an action as provided in paragraph (a), and MERCK elects to do so, the costs of any agreed-upon course of
action to terminate infringement of AVEO Patent Rights or misappropriation or misuse of AVEO Know-How, including without limitation the costs of any legal action commenced or the defense of any declaratory judgment, shall be [**] by AVEO and MERCK;
provided that MERCK shall pay all such costs and shall recoup AVEO’s [**] percent ([**]%) share as a set-off against royalties or milestones until AVEO’s share has been fully paid; provided further that the royalty payment to
AVEO in any Calendar Quarter shall not, as a result of the setoffs provided in this section and Section 7.1(d) and the reduction set forth in Section 5.4.5, be reduced by more than [**] percent ([**]%) of the amount otherwise owed to AVEO;
and any amounts not able to be reduced due to the immediately foregoing limitation shall be carried forward to future Calendar Quarters for crediting against future royalties in such country. 

  

 -41- 

	 	(c)	For any action to terminate any infringement of AVEO Patent Rights or any misappropriation or misuse of AVEO Know-How, in the event that MERCK is unable to initiate or
prosecute such action solely in its own name, AVEO will join such action voluntarily and will execute and cause its Affiliates to execute all documents necessary for MERCK to initiate litigation to prosecute and maintain such action. In connection
with any action, MERCK and AVEO will cooperate fully and will provide each other with any information or assistance that either may reasonably request. Each Party shall keep the other informed of developments in any action or proceeding, including,
to the extent permissible by law, the consultation and approval of any settlement negotiations and the terms of any offer related thereto. 

  

	 	(d)	Any recovery obtained by either or both MERCK and AVEO in connection with or as a result of any action contemplated by this section, whether by settlement or otherwise,
shall be shared in order as follows: 

  

	 	(i)	the Party which initiated and prosecuted the action shall recoup all of its costs and expenses incurred in connection with the action; 

  

	 	(ii)	the other Party shall then, to the extent possible, recover its costs and expenses incurred in connection with the action; 

  

	 	(iii)	the amount of any recovery remaining from ordinary damages shall then be allocated between the Parties such that MERCK shall receive an amount equal to its lost profits
or a reasonable royalty on the infringing sales, or whichever measure of damages the court shall have applied, and that AVEO shall receive a reasonable approximation of the royalties and other amounts that MERCK would have paid to AVEO if MERCK had
sold the infringing products rather than the infringer, and on a pro rata basis taking into consideration the relative economic losses suffered by each Party; and 

  

	 	(iv)	the amount of any recovery remaining from special or punitive damages shall be [**] in any such award. 

  

	 	(e)	Any recovery obtained by MERCK or its Related Parties as a result of any action relating to Third Party infringement based upon MERCK Patent Rights or Joint Patent
Rights, whether by settlement or otherwise, shall, after MERCK has recouped all of its costs and expenses incurred in connection with such action, be deemed to constitute Net Sales of Products for which royalties are payable under Section 5.4.

  

 -42- 

	 	(f)	AVEO shall inform MERCK of any certification regarding any AVEO Patent Rights it has received pursuant to either 21 U.S.C. §§355(b)(2)(A)(iv) or
(j)(2)(A)(vii)(IV) or it successor provisions or any similar provisions in a country in the Territory other than the United States and shall provide MERCK with a copy of such certification within five (5) days of receipt. AVEO’s and
MERCK’s rights with respect to the initiation and prosecution of any legal action as a result of such certification or any recovery obtained as a result of such legal action shall be as defined in paragraphs 7.3(a)-(d) hereof;
provided, however, AVEO shall exercise its first right to initiate and prosecute any action and shall inform MERCK of such decision within ten (10) days of receipt of the certification, after which time MERCK shall have the right
to initiate and prosecute such action. 

  

	7.4	Patent Term Extension 

 The Parties hereto shall cooperate with each other in obtaining patent term extension or supplemental protection certificates or their equivalents in any country in the Territory where applicable to AVEO Patent Rights, MERCK Patent Rights
and/or Joint Patent Rights. In the event that elections with respect to obtaining such patent term extension are to be made, MERCK shall have the right to make the election and AVEO agrees to abide by such election. 
  

	8.	TERM AND TERMINATION 

  

	8.1	Term and Expiration 

 This Agreement shall be effective as of the Effective Date and unless terminated earlier pursuant to Sections 8.2 or 8.3 below, this Agreement shall continue in effect until expiration of all royalty obligations hereunder. Upon expiration
of this Agreement, MERCK’s licenses pursuant to Section 3.1 shall become fully paid-up, perpetual licenses. 
  

	8.2	Termination of Agreement by MERCK 

 Notwithstanding anything contained herein to the contrary, MERCK shall have the right to terminate this Agreement at any time in its sole discretion by giving one hundred twenty (120) days’
advance written notice to AVEO. Not later than thirty (30) days after the date of such termination, each Party shall return or cause to be returned to the other Party all Information in tangible form received from the other party and all copies
thereof, except that each Party may retain one copy in its confidential files for records purposes. In the event of termination under this Section 8.2: (i) each Party shall pay all amounts then due and owing as of the termination date; and
(ii) except for the provisions of Section 8.3.2(b) and the surviving provisions set forth in Section 8.4 hereof, the rights and obligations of the Parties hereunder shall terminate as of the date of such termination; provided,
however, that MERCK shall have a fully paid-up non-exclusive license to use AVEO Information and Inventions and AVEO’s interest in Joint Information and Inventions for Internal Research Purposes. 
  

 -43- 

	8.3	Termination of Agreement for Cause 

  

	8.3.1 	Cause for Termination. This Agreement may be terminated at any time during the term of this Agreement upon written notice by either Party if the
other Party is in breach of its material obligations hereunder and has not cured such breach within [**] days after notice requesting cure of the breach (other than for non-payment which must be cured within [**] days); provided,
however, in the event of a good faith dispute with respect to the existence of a material breach, the [**] day or [**] day cure period shall be tolled until such time as the dispute is resolved pursuant to Section 9.6 hereof.

  

	8.3.2 	Effect of Termination on License 

  

	 	(a)	If MERCK terminates this Agreement under Section 8.3.1, (i) at MERCK’s option MERCK’s licenses pursuant to Section 3.1 shall become perpetual
licenses; provided, however, MERCK shall continue to fulfill MERCK’s payment and/or royalty obligations as specified herein, and provided, further, MERCK may reduce such payment and/or royalty obligations by the
amount of monetary damage suffered by MERCK as a direct result of AVEO’s breach of this Agreement; and (ii) AVEO shall, within thirty (30) days after such termination return or cause to be returned to MERCK all MERCK Information in
tangible form, and all substances or compositions delivered or provided by MERCK, as well as any other material provided by MERCK in any medium. 

  

	 	(b)	If AVEO terminates this Agreement under Section 8.3.1 or if MERCK terminates under Section 8.2, MERCK’s licenses pursuant to Section 3.1 shall
terminate and the covenant not to sue in Section 3.2.1 shall terminate as of such termination date, and MERCK shall, within thirty (30) days after such termination, return or cause to be returned to AVEO all Information in tangible form
and substances or compositions delivered or provided by AVEO, as well as any other material provided by AVEO in any medium. In the event of termination pursuant to this Section 8.3.2(b), MERCK shall, upon AVEO’s request, provide to AVEO
the MERCK Non-MAP Collaboration Target Data Package for each Non-MAP Collaboration Target, and MERCK Discovery Target Data Package for each Discovery Target, and AVEO shall be permitted to use and otherwise exploit the information contained in such
MERCK Non-MAP Collaboration Target Data Package or MERCK Discovery Target Data Package for research and commercialization purposes; provided, however, that MERCK shall retain the right to use Joint Information and Inventions and MERCK
Information and Inventions for all purposes outside the Field, and relating to such Non-MAP Collaboration Target or Discovery Target for Internal Research Purposes in the Field. In the event of termination pursuant to this Section 8.3.2(b),
AVEO and MERCK shall, at AVEO’s request made within [**] days of AVEO’s receipt of any MERCK Discovery Target Data Package pursuant to this Section, negotiate in good faith concerning the license to AVEO of compounds discovered or
developed by MERCK Directed to such Discovery Target that MERCK, in its sole discretion, elects to out-license, upon terms to be negotiated in good faith by the Parties and reflected in a separate agreement. For the avoidance of doubt, MERCK shall
be under no obligation to enter any agreement with AVEO, to provide AVEO with any particular terms in comparison to any other potential licensee, or to give AVEO preference over any other potential licensee. 

  

 -44- 

	 	(c)	Upon termination of this Agreement by MERCK pursuant to Section 8.2, or by AVEO pursuant to Section 8.3.1, MERCK and its Affiliates, sublicensees and
distributors shall be entitled, during the [**] month period immediately following the effective date of termination, to finish any work-in-progress and to sell any Products or Collaboration Compound remaining in inventory, in accordance with the
terms of this Agreement. Except as otherwise provided in the foregoing sentence, upon termination of this Agreement by MERCK pursuant to Section 8.2, or by AVEO pursuant to Section 8.3.1, MERCK and its Affiliates shall not (a) use,
make, have made, offer to sell, sell or import any Collaboration Compound or Product except for Internal Research Purposes, or (b) utilize any Non-MAP Collaboration Target or Potential Collaboration Target except for Internal Research Purposes.

  

	8.4	Effect of Expiration or Termination; Survival 

 Expiration or termination of the Agreement shall not relieve the Parties of any obligation accruing prior to such expiration or termination. Any expiration or termination of this Agreement shall be
without prejudice to the rights of either Party against the other accrued or accruing under this Agreement prior to expiration or termination, including without limitation the obligation to pay royalties for Product(s) or Collaboration Compound(s)
sold prior to such expiration or termination. The provisions of Article 4 shall survive the expiration or termination of the Agreement and shall continue in effect for ten (10) years. In addition, the provisions of Articles 7, 8 and 9, and
Section 5.5, and definitions related thereto, shall survive any expiration or termination of this Agreement. 
  

	9.	MISCELLANEOUS 

  

	9.1	Force Majeure 

 Neither Party shall be held liable to the other Party nor be deemed to have defaulted under or breached the Agreement for failure or delay in performing any obligation under the Agreement when such failure or delay is caused by or results

disturbances, fire, floods, or other acts of God, or acts, omissions or delays in acting by any governmental authority or the other Party. The affected Party shall notify the other Party of such force majeure circumstances as soon as reasonably
practical, and shall promptly undertake all reasonable efforts necessary to cure such force majeure circumstances. 
  

	9.2	Assignment/Change of Control.

hereunder in whole or in part to an Affiliate of MERCK or in connection with a Change of Control. 
 (c) AVEO may, without
MERCK’s consent, assign this Agreement and its rights and obligations hereunder to a wholly-owned subsidiary of AVEO or in connection with a Change of Control; provided, however, that in the event of a Major Pharma Change of
Control, AVEO shall provide written notice to MERCK at least [**] days prior to the completion of such Major Pharma Change of Control and MERCK shall have the right, at its election (such election to be made within [**] days after such notice) to
implement some or all of the following revisions to this Agreement: 
  

	 	(i)	to the extent that provisions of the Agreement require MERCK to provide MERCK Know-How and other information regarding the Collaboration to AVEO, such provisions shall
be automatically amended to no longer impose such an obligation on MERCK; 

  

	 	(ii)	the provisions of the Agreement providing for the participation of AVEO in decision-making through the Committee (including but not limited to Section 2.4) shall
be of no further force and effect; and 

  

	 	(iii)	MERCK shall be entitled to terminate the Research Program as provided in Section 2.8.2, provided, however, that such termination shall be deemed to

royalty obligations. 
 (e) Any attempted assignment not in accordance with this Section 9.2 shall be void. 
  

	9.3	Severability 

 If
any one or more of the provisions contained in this Agreement is held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or
impaired thereby, unless the absence of the invalidated provision(s) adversely affects the substantive rights of the Parties. The Parties shall in such an instance use their best efforts to replace the invalid, illegal or unenforceable provision(s)
with valid, legal and enforceable provision(s) which, insofar as practical, implement the purposes of this Agreement.

 -47- 

	9.6	Dispute Resolution 

  

	9.6.1 	The Parties shall negotiate in good faith and use reasonable efforts to settle any dispute, controversy or claim arising from or related to this Agreement or the breach
thereof. If the Parties do not fully settle, and a Party wishes to pursue the matter, each such dispute, controversy or claim that is not an “Excluded Claim” shall be finally resolved by binding arbitration in accordance with the
Commercial Arbitration Rules and Supplementary Procedures for Large Complex Disputes of the American Arbitration Association (“AAA”), and judgment on the arbitration award may be entered in any court having jurisdiction thereof.

  

	9.6.2 	The arbitration shall be conducted by a panel of three persons experienced in the pharmaceutical business: within 30 days after initiation of arbitration, each
Party shall select one person to act as arbitrator and the two Party-selected arbitrators shall select a third arbitrator within 30 days of their appointment. If the arbitrators selected by the Parties are unable or fail to agree upon the third
arbitrator, the third arbitrator shall be appointed by the AAA. The place of arbitration shall be New York, New York, and all proceedings and communications shall be in English. 

  

	9.6.3 	Either Party may apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Either
Party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party pending the arbitration award. The arbitrators
shall have no authority to award punitive or any other type of damages not measured by a Party’s compensatory damages. Each Party shall bear its own costs and expenses and attorneys’ fees and an equal share of the arbitrators’ and any
administrative fees of arbitration. 

  

	9.6.4 	Except to the extent necessary to confirm an award or as may be required by law or regulation, neither a Party nor an arbitrator may disclose the existence,
content, or results of an arbitration without the prior written consent of both Parties. In no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim
would be barred by the applicable New York statute of limitations. 

  

	9.6.5 	The parties agree that, in the event of a dispute over the nature or quality of performance under this Agreement, neither party may terminate the Agreement until
final resolution of the dispute through arbitration or other judicial determination. The parties further agree that any payments made pursuant to this Agreement pending resolution of the dispute shall be refunded if an arbitrator or court determines
that such payments are not due. 

  

	9.6.6 	As used in this Section, the term “Excluded Claim” means a dispute, controversy or claim that concerns (a) the validity or infringement of
a patent, trademark or copyright; or (b) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory. 

  

 -48- 

	9.7	Entire Agreement; Amendments

respect to the Research Program and licenses granted hereunder; provided, however, that the Parties acknowledge and agree that the rights and obligations that accrued under the Prior Agreement shall remain in effect pursuant to the
terms and conditions of this Agreement. All express or implied agreements and understandings, either oral or written, with regard to the Research Program and the licenses granted hereunder are superseded by the terms of this Agreement. The Agreement

of any kind, or to take any action, which shall be binding on AVEO, without the prior written consent of AVEO. 
  

	9.10	Waiver

similar nature or otherwise.

 GENPATH PHARMACEUTICALS AND MERCK ENTER INTO POTENTIAL $100 
 MILLION DEAL FOR THE DISCOVERY OF NOVEL CANCER DRUGS 
 CAMBRIDGE, MA October XX, 2003 – GenPath Pharmaceuticals, Inc., a drug discovery and development company focused on the treatment of cancer and other diseases, announced today that it has entered
into a multi-year collaborative agreement with Merck & Co., Inc. (NYSE: MRK). Under the agreement, GenPath will use its proprietary cancer models to identify essential tumor maintenance genes which maybe suitable targets for the development
of small molecule oncology agents. GenPath will also use its inducible, spontaneous tumor models to guide candidate drug selection and optimization. 
 Under the agreement, Merck will have an exclusive option to obtain exclusive worldwide license rights to a specified number of small molecule targets discovered and validated in a selected group of GenPath models. GenPath’s models will
also be used in downstream drug discovery and optimization activities to guide the selection of the appropriate candidates to move into development. Merck will be responsible for drug discovery, clinical development and commercialization of the
resulting products. 
 Under the terms of the agreement, GenPath will receive a significant upfront payment plus annual research funding, as
well as potential milestones and royalties from Merck. Total payments to GenPath by Merck based on the successful commercialization of multiple products resulting from the collaboration, exclusive of royalties, could exceed $100 million. 

“Despite recent technological advances, there remains a huge unmet medical need in the treatment of most types of cancer. Merck has made a strategic
commitment to address the challenges of developing novel and efficacious therapies in cancer. . Our partnership with GenPath, is a very important element of our cancer research strategy. ,” said Stephen Friend, M.D., Ph.D., senior vice
president, Molecular Profiling and Cancer Research at Merck.
