Waiver of any one breach shall not be deemed to be a waiver of any other breach of the same or any other provisions hereof.

     (b) If any provision of this General Release or any part of any such provision is held under any circumstances to be invalid or unenforceable in any jurisdiction, then (i) such provision or part thereof shall, with respect to such circumstances and in such jurisdiction, be deemed amended to conform to applicable laws so as to be valid and enforceable to the fullest possible extent, (ii) the invalidity or unenforceability of such provision or part thereof under such circumstances and in such jurisdiction shall not affect the validity or enforceability of such provision or part thereof under any other circumstances or in any other jurisdiction, and (iii) such invalidity or enforceability of such provision or part thereof shall not affect the validity or enforceability of the remainder of such provision or the validity or enforceability of any other provision of this General Release. Each provision of this General Release is separable from every other provision of this General Release, and each part of each provision of this General Release is separable from every other part of such provision.

Arbitration shall be conducted by a single arbitrator selected by the parties who shall be qualified by training and experience to pass upon the matter of the dispute and shall not have to power to add to, ignore or modify any term or condition of this Agreement. In the event the parties are unable to agree upon a single arbitrator within a thirty (30) day period, the arbitrator shall be selected by JAMS. The arbitration decision shall not go beyond what is necessary for the interpretation and application of this Agreement and shall be in writing and shall set forth findings of fact and conclusions of law, as appropriate, supported by a reasoned opinion. The cost of such arbitration shall be borne as determined by the arbitrator; provided however, each party shall bear the costs of preparing and presenting its own case.
