It is expressly understood and agreed that if any provision of this Agreement or the application of any such provision to any party or circumstance shall be determined by any court of competent jurisdiction to be invalid or unenforceable to any extent, the remainder of this Agreement, or the application of such provision to any party or circumstance other than those to which it is so determined to be invalid or unenforceable, shall not be affected thereby, and each provision hereof shall be enforced to the fullest extent permitted by law so long as the economic or legal substance of the matters contemplated by this Agreement is not affected in any manner materially adverse to any party.  If the final judgment of a court of competent jurisdiction declares or finds that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration or portion of the term or provision, or to delete specific words or phrases, and to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified.  If such court of competent jurisdiction does not so replace an invalid or unenforceable term or provision, the parties hereto will negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the matters contemplated hereby are fulfilled to the fullest extent possible.
