Section 17.5.1. In rendering its or their decision the arbitrator or arbitrators shall apply the substantive law of the State of New York, without regard to its conflict of laws provisions, except that the interpretation of an
enforcement of this Section 17.5 shall be governed by the U.S. Federal Arbitration Act. Proceedings shall be conducted in New York and the fees of the arbitrator or arbitrators shall be shared equally by the parties. Nothing herein shall
prevent either party from seeking injunctive or other interim relief from a court of competent jurisdiction in order to protect such party’s intellectual property rights and/or Confidential Information. 

17.6 Waiver. The failure of either party to enforce at any time any of the provisions of this Agreement, or the failure to require at
any time performance by the other party of any of the provisions of this Agreement, shall in no way be construed to be a present or future waiver of such provisions, nor in any way affect the right of either party to enforce each and every such
provision thereafter. The express waiver by either party of any provision, condition or requirement of this Agreement shall not constitute a waiver of any future obligation to comply with such provision, condition or requirement.
