Judgement upon the award rendered by the arbitration may be entered in any court having jurisdiction thereof. 17. Entire Agreement. This Agreement (a) constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter of this Agreement and (b) is not intended to confer upon any person other than the parties hereto any rights or remedies. 18. Counterparts. This Agreement may be executed in any number of duplicate counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument. 13 19. Severability. In the event any of the provisions of this Agreement are held to be unenforceable or invalid by any court of competent jurisdiction, unless the unenforceability or invalidity thereof causes a substantial departure from the underlying intent and sense of the remainder of this Agreement, the validity and enforceability of the remaining provisions shall not be affected thereby, except those remaining provisions of which the unenforceable or invalidated provisions comprise an integral part or from which they are otherwise clearly inseparable. In the event any provision is held unenforceable or invalid, the parties shall use their best efforts to agree upon an enforceable and valid provision which shall be a reasonable substitute for such unenforceable or invalid provision in light of the purpose of this Agreement and, upon so agreeing, shall incorporate such substitute provision in this Agreement. 20. Headings. Headings of sections in this Agreement are inserted for convenience of reference only and are not intended to be part of or to affect the meaning or interpretation of this Agreement. 21. Amendments. This Agreement may be modified, amended or supplemented only by the mutual written agreement of the parties hereto.
