by each such Party in connection with the initiation and/or prosecution of such action.

MERCK shall have the right, at its election (such election to be made within ninety (90) 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 Research Program 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 shall be of no further force and effect; and


  

	 	(iii)	MERCK shall be entitled to terminate the Research Program as provided in Section 2.9.2.

 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

with valid, legal and enforceable provision(s) which, insofar as practical, implement the purposes of this Agreement.

 This Agreement shall be governed by and construed in accordance with the laws of the State of New Jersey and the patent laws of the United States, without reference to any rules of conflict of laws. The United Nations Convention on the Sale
of Goods shall not apply. 
  

	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

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. 

  

 29 









	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. 

  

	9.7	Entire Agreement; Amendments 

 This Agreement contains the entire understanding of the Parties with respect to the Research Program and the licenses granted hereunder. Any other express or implied agreements and understandings, either
oral or written, with regard to the Research Program or the licenses granted hereunder are superseded by the terms of this Agreement. This Agreement may be amended, or any term hereof modified, only by a written instrument duly-executed by

	9.10	Waiver 

 The waiver
by either Party hereto of any right hereunder, or of any failure of the other Party to perform, or of any breach by the other Party, shall not be deemed a waiver of any other right hereunder or of any other breach by or failure of such other Party,
whether of a similar nature or otherwise.
