AGREEMENT

NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein and other good and valid consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as follows:

Section 1.    Voting, Waiver and Enforcement

Platinum agrees (i) to cause each share of common stock of the Company entitled to vote on the relevant matter and beneficially owned by it to be voted in favor of the directors nominated for the board of directors of the Company pursuant to Section 2.3(b)(i) of the Company’s by-laws, and (ii) to cause each share of common stock of the Company entitled to vote pursuant to Section 2.5 of the Company’s by-laws and beneficially owned by Platinum to be voted proportionately as the shares voted by all Other Holders (as defined in the Company’s by-laws) (including, with respect to each (i) and (ii) above, if applicable, through the execution of one or more written consents if stockholders of the Company are requested to vote by written consent in lieu of any annual or special meeting of stockholders of the Company). Platinum and the Company agree that any decision or action by the Company to waive or enforce this Agreement shall be duly made or taken, as applicable, solely by the decision of the two Designated Other Directors (as defined in the Company’s by-laws) and any directors nominated pursuant to Section 2.3(b)(i) of the Company’s by-laws, or their successors. Platinum and the Company shall take any and all actions reasonably requested of them by the two Designated Other Directors (or their successors) in order to give effect to the provisions of this Agreement.

Section 2.    Miscellaneous.

(a)    No Conflicting Agreements. The parties have not and shall not enter into any agreement inconsistent with the provisions hereof.

(b)    Remedies; Specific Performance. In the event of a breach or a threatened breach by any party to this Agreement of its obligations under this Agreement, any party injured or to be

injured by such breach shall be entitled to specific performance of its rights under this Agreement or to injunctive relief, in addition to being entitled to exercise all rights provided in this Agreement and granted by law, it being agreed by the parties that the remedy at law, including monetary damages, for breach of any such provision will be inadequate compensation for any loss and that any defense or objection in any action for specific performance or injunctive relief for which a remedy at law would be adequate is hereby waived.

(c)    No Waivers. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

(d)    Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the law of any jurisdiction other than the State of New York.

(e)    Jurisdiction and Venue. The parties hereto hereby irrevocably submit to the jurisdiction of either a state or federal court of competent jurisdiction in the County of New York in the State of New York (the “New York Court”) in respect of the interpretation and enforcement of the provisions of this Agreement and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby, and hereby waive, and agree not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or of any such document, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in any New York Court, or that this Agreement or any such document may not be enforced in or by such courts, and the parties hereto irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined in a New York Court. The parties hereto hereby consent to and grant any New York Court jurisdiction over the person of such parties and, to the extent permitted by law, over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 2(f) or in such other manner as may be permitted by law shall be valid and sufficient service thereof. EACH OF THE PARTIES IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHTS TO TRIAL BY JURY IN CONNECTION WITH ANY PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.
