     Section 5.5 Enforcement of this Agreement. The parties hereto acknowledge and agree that an award of money damages would be inadequate for any breach of this Agreement by any party and any such breach would cause the non-breaching parties irreparable harm. Accordingly, the parties hereto agree that, in the event of any breach or threatened breach of this Agreement by one of the parties, the parties will also be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance, provided such party is not in material default hereunder. Such remedies will not be the exclusive remedies for any breach of this Agreement but will be in addition to all other remedies available at law or equity to each of the parties.

Except as set forth in Section 5.8, the parties agree that the indemnification provisions in this Article V shall be the exclusive remedy of the parties with respect to breaches of representations and warranties and failures to perform covenants or agreements hereunder.

     Section 5.8 No Waiver Relating to Claims for Fraud/Willful Misconduct. The liability of any party under this Article V shall be in addition to, and not exclusive of, any other liability that such party may have at law or in equity based on such party’s (a) fraudulent acts or

13

omissions or (b) willful misconduct. None of the provisions set forth in this Agreement shall be deemed to be a waiver by or release of any party of any right or remedy which such party may have at law or equity based on any other party’s fraudulent acts or omissions or willful misconduct nor shall any such provisions limit, or be deemed to limit, (i) the amounts of recovery sought or awarded in any such claim for fraud or willful misconduct, (ii) the time period during which a claim for fraud or willful misconduct may be brought, or (iii) the recourse which any such party may seek against another party with respect to a claim for fraud or willful misconduct.

No supplement, modification or waiver of this Agreement shall be binding unless executed in writing by the party to be bound thereby. The failure of a party to exercise any right or remedy shall not be deemed or constitute a waiver of such right or remedy in the future. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (regardless of whether similar), nor shall any such waiver constitute a continuing waiver unless otherwise expressly provided.

     Section 6.4 Binding Effect and Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns. Nothing in this Agreement, express or implied, is intended to confer upon any person other than the parties hereto and their respective permitted successors and assigns, any rights, benefits or obligations hereunder. No party hereto may assign, transfer, dispose of or otherwise alienate this Agreement or any of its rights, interests or obligations under this Agreement (whether by operation of law or otherwise). Any attempted assignment, transfer, disposition or alienation in violation of this Agreement shall be null, void and ineffective.

     Section 6.5 Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of applicable Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated herein are not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the transactions contemplated herein are consummated as originally contemplated to the fullest extent possible.
