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.
