The Parties agree that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(c) Should any term or provision of this Agreement for any reason be declared invalid or unenforceable, such decision shall not affect the validity or enforceability of any of the other terms or provisions of this Agreement, which other terms and provisions shall remain in full force and effect and the application of such invalid or unenforceable term or provision to Persons or circumstances other than those as to which it is held invalid or unenforceable shall be valid and be enforced to the fullest extent permitted by law. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the Parties agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such 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 that this Agreement shall be valid and enforceable as so modified.

(d) EACH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT.

8. Entire Agreement.

This Agreement and the Stockholders Agreement constitutes the entire agreement among the Parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof. There are no restrictions, promises, warranties, covenants or undertakings between the Parties, other than those expressly set forth or referred to herein. Unless otherwise provided herein, any consent required by the Corporation may be withheld by the Corporation in its sole discretion.

9. Inconsistent Arrangements; Specific Performance.

(a) No Party shall enter into any agreements or arrangements of any kind with any Person with respect to any Shares on terms inconsistent with the provisions of this Agreement (whether or not such agreements or arrangements are with Persons that are Parties to this Agreement), including agreements or arrangements with respect to the acquisition or disposition of any Shares in a manner inconsistent with this Agreement.

(b) Each Party acknowledges that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms and that a remedy at law for any breach or attempted breach of this Agreement will be inadequate. It is accordingly agreed that the Parties shall be entitled to specific performance and injunctive and other equitable relief in case of any such breach or attempted breach and to enforce specifically the terms and provisions hereof, and further agrees to waive (to the extent legally permissible) any legal conditions required to be met for the obtaining of any such injunctive or other equitable relief (including securing or posting any bond in order to obtain equitable relief). Each Party further agrees that, in the event of any action for an injunction or other equitable remedy in respect of such breach or enforcement of specific performance, it will not assert the defense that a remedy at law would be adequate.

10. Counterparts.

This Agreement may be executed in counterparts, all of which together shall constitute an agreement binding on all Parties hereto, notwithstanding that all such Parties are not signatories to the original or the same counterpart. Facsimile copies of signatures shall constitute original signatures for all purposes of this Agreement and any enforcement hereof. The failure of any Stockholder to execute this Agreement shall not make it invalid as against any other Stockholder.

11. No Recourse.

This Agreement may only be enforced against, and any claims or cause of action that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement may only be made against, the Persons that are expressly identified as Parties hereto and no past, present or future Affiliate, director, officer, employee, incorporator, member, manager, partner, stockholder, agent, attorney or representative of any Party hereto shall have any liability for any obligations or liabilities of the Parties to this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby.
