“INFORMATION”) shall be disclosed and used by the parties subject to the following terms and conditions: 
  

	1.	MERCK and WXPT shall keep all INFORMATION of the other party in confidence and will not, without the disclosing party's prior written consent, disclose any INFORMATION of the
disclosing party to any person or entity, except those officers, employees, agents, or AFFILIATES of the receiving party who directly require the INFORMATION. Each officer, employee, agent, or AFFILIATE to whom INFORMATION is to be disclosed shall
be advised by the receiving party of the terms of this AGREEMENT and shall be bound by the confidentiality and non-use obligations herein, mutatis mutandis. Both parties shall take all reasonable precautions to prevent INFORMATION of the

 PROPRIETARY INFORMATION

	3.	The obligations of confidentiality set forth herein shall not apply to any INFORMATION that is: 

  

	 	(a)	lawfully possessed at any time by the receiving party prior to receipt from the disclosing party, as evidenced by the receiving party's written records; or 


 

	 	(b)	published or available to the general public otherwise than through the receiving party's breach of this AGREEMENT, or its breach of any other obligation of confidentiality; or


  

	 	(c)	obtained by the receiving party from a third party with a valid right to disclose such INFORMATION, provided that said third party is not under a confidentiality obligation to the
disclosing party; or 

  

	 	(d)	independently developed by employees or agents of the receiving party who had no knowledge of the disclosing party's INFORMATION, as evidenced by the receiving party's written

rightful possession of the receiving party. 
  

	4.	All INFORMATION, without limitation, shall remain the property of the disclosing party. Neither party shall acquire any license or any other intellectual property interest in any

potential concerns regarding cross-contamination or regulatory requirements. In the event MERCK identifies such a potential concern, the parties will negotiate in good faith a resolution thereto. Notwithstanding the foregoing, WXPT shall not conduct
any CROSS-CONTAMINATION ACTIVITIES that MERCK identifies as presenting such a potential concern. 

  

	8.	Upon the written request of the disclosing party, the receiving party shall immediately either return to the disclosing party, or destroy, all INFORMATION of the disclosing party,

the disclosing party and allow the disclosing party a reasonable time and opportunity to oppose such process before disclosing any INFORMATION. 

  

	10.	No agency or partnership relationship between MERCK and WXPT, either express or implied, shall be created by this AGREEMENT. Each party agrees to keep the existence and nature of
the relationship between the parties as well as the terms of this AGREEMENT confidential and not to use the names of the other parties in any publicity or advertisement with regard to this AGREEMENT, without the prior written consent of the other
party.

	11.	The confidentiality and non-use obligations created by this AGREEMENT shall be binding upon MERCK and WXPT, and shall inure to the benefit of, and be enforceable by, their
respective successors and assigns, and shall continue with respect to each item of INFORMATION until the earlier of (i) the occurrence of any of the conditions set forth in SECTION 3 with respect to such item, or (ii) the longest period
permitted by applicable law. 

  

	12.	This AGREEMENT embodies the entire understanding of the parties with respect to the subject matter hereof and supersedes and replaces any and all prior understandings and
arrangements, oral or written, relating to the INFORMATION except for any other confidentiality agreement between or among the parties hereto. 

  

	13.	This AGREEMENT shall be interpreted, construed and enforced in accordance with the laws of the State of New Jersey, without regard or reference to any of its rules or provisions
governing conflict of laws. 

  

	14.	The parties shall attempt to resolve amicably any dispute arising out of or relating to this AGREEMENT through good faith negotiations. In the event that said negotiations are not
successful, the dispute shall be resolved through arbitration before three (3) arbitrators. Such arbitration shall take place in Somerset County, New Jersey and shall proceed in accordance with the Commercial Arbitration Rules of the
International Chamber of Commerce (“ICC”) and the laws of the State of New Jersey without regard or reference to any of its rules or provisions governing conflict of laws. Within seven (7) calendar days of either party making a demand
for arbitration, MERCK and WXPT shall each select one (1) arbitrator. Within thirty (30) days of a demand for arbitration, a third arbitrator shall be selected by the arbitrators selected by the parties. If, within the prescribed time,
either party shall fail to appoint its arbitrator, or the two arbitrators selected by the parties fail to appoint the third arbitrator, then either party may apply to the ICC for the appointment of such third arbitrator. The determination of a
majority of the panel of arbitrators shall be the decision of the arbitrators and shall be binding upon the parties regardless of whether one of the parties fails or refuses to participate in the arbitration. The decision of the arbitrators shall be
enforceable by any court of competent jurisdiction. Each party shall pay for its arbitrator, with all fees and expenses of the third arbitrator being split equally between the parties. All other expenses directly associated with holding an
arbitration proceeding shall be split equally between the parties. Either party may enter any arbitration award in any court having jurisdiction or may make application to any such court for a judicial acceptance of the award and an order of
enforcement, as the case may be. 

  

	15.	Notwithstanding anything to the contrary in SECTION 14, each party understands and agrees that any use or disclosure of INFORMATION of the other party in violation of this AGREEMENT
will cause such other party irreparable harm leaving it without an adequate legal remedy and shall therefore entitle the other party, among all other remedies, to injunctive relief from any court having jurisdiction. 

  

 PROPRIETARY INFORMATION

	16.	If any provision of this AGREEMENT is found invalid or unenforceable by a court of competent jurisdiction, the remainder of this AGREEMENT shall continue in full force and effect.
The parties shall negotiate in good faith to substitute a valid, legal, and enforceable provision that reflects the intent of such invalid or unenforceable provision. 

  

	17.	It is understood and agreed that no failure or delay by either party in exercising any right, power, or privilege hereunder shall operate as a waiver thereof, nor shall any single
or partial exercise thereof preclude any other or further exercise thereof or the exercise of any right, power, or privilege hereunder.
