9.4 Severability. If any term or provision of this Agreement is invalid, illegal or incapable of being enforced by rule of 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 by this Agreement is not affected in any manner adverse to any party. 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 as closely as possible in an acceptable manner to the end that the transactions are fulfilled to the extent possible.

9.5 Entire Agreement; Amendment. This Agreement, the Proxy and any other documents delivered by the parties in connection herewith constitute the entire agreement between the parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, written or oral, between the parties with respect thereto.

-8-

shall be void. Subject to the preceding sentence, this Agreement shall be binding upon Stockholder and Stockholder’s successors and assigns, and, if Stockholder is an individual, Stockholder’s heirs, estate, executors and personal representatives. This Agreement shall inure to the benefit of Parent and its successors and assigns. Without limiting any of the restrictions set forth in Section 2 or elsewhere in this Agreement, this Agreement shall be binding upon any Person to whom any Subject Securities are transferred. Nothing in this Agreement, expressed or implied, is intended to confer on any Person, other than the parties hereto, any rights or remedies of any nature.

9.7 Independence of Obligations. The covenants and obligations of Stockholder set forth in this Agreement shall be construed as independent of any other agreement or arrangement between Stockholder, on the one hand, and the Company or Parent, on the other.

9.8 Specific Performance. THE PARTIES AGREE THAT IRREPARABLE DAMAGE WOULD OCCUR IN THE EVENT THAT ANY OF THE PROVISIONS OF THIS AGREEMENT WERE NOT PERFORMED IN ACCORDANCE WITH THEIR SPECIFIC TERMS OR WERE OTHERWISE BREACHED. IT IS ACCORDINGLY AGREED THAT (A) THE PARTIES SHALL BE ENTITLED TO AN INJUNCTION OR INJUNCTIONS TO PREVENT BREACHES OF THIS AGREEMENT AND TO ENFORCE SPECIFICALLY THE TERMS AND PROVISIONS OF THIS AGREEMENT IN THE CHANCERY COURT OF THE STATE OF DELAWARE OR ANY FEDERAL COURT SITTING IN THE CITY OF NEW YORK, WITHOUT PROOF OF DAMAGES OR BOND OR OTHER SECURITY BEING REQUIRED, THIS BEING IN ADDITION TO ANY OTHER REMEDY TO WHICH THEY ARE ENTITLED AT LAW OR IN EQUITY AND (B) THE RIGHT OF SPECIFIC PERFORMANCE IS AN INTEGRAL PART OF THE TRANSACTIONS AND WITHOUT THAT RIGHT, NONE OF THE COMPANY, PARENT OR PURCHASER WOULD HAVE ENTERED INTO THIS AGREEMENT. EACH OF THE PARTIES HERETO AGREES THAT IT WILL NOT OPPOSE THE GRANTING OF AN INJUNCTION, SPECIFIC PERFORMANCE AND OTHER EQUITABLE RELIEF ON THE BASIS THAT THE OTHER PARTIES HERETO HAVE AN ADEQUATE REMEDY AT LAW OR AN AWARD OF SPECIFIC PERFORMANCE IS NOT AN APPROPRIATE REMEDY FOR ANY REASON AT LAW OR EQUITY.

9.9 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, applicable to contracts executed in and to be performed entirely within that State.

9.10 Counterparts. This Agreement may be executed in separate counterparts, each of which when so executed and delivered shall be an original, but all such counterparts shall together constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by facsimile or by electronic delivery shall be sufficient to bind the parties to the terms of this Agreement.

-9-

9.11 Waiver. No failure on the part of Parent to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of Parent in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. Parent shall not be deemed to have waived any claim available to Parent arising out of this Agreement, or any power, right, privilege or remedy of Parent under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of Parent; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

9.12 Termination. This Agreement and all rights and obligations of the parties hereunder, including the Proxy, shall terminate, and no party shall have any rights or obligations hereunder and this Agreement shall become null and void on, and have no further effect as of the Proxy Expiration Date. Nothing in this Section 9.12 shall relieve any party from any liability for any breach of this Agreement prior to its termination.

9.13 Directors and Officers. This Agreement applies to Stockholder solely in such Stockholder’s capacity as a holder of Subject Securities, and not to Stockholder or any representative of Stockholder serving as a director or officer of the Company in such capacity.

9.14 Construction.

(b) The parties agree that any rule of construction to the effect that ambiguities are to be resolved against the drafting party shall not be applied in the construction or interpretation of this Agreement.

(c) As used in this Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.”

(The shares of the capital stock of the Company referred to in clauses “(i)” and “(ii)” of the immediately preceding sentence are collectively referred to as the “Shares”). Upon the execution hereof, all prior proxies given by the Stockholder with respect to any of the Shares are hereby revoked, and the Stockholder agrees that no subsequent proxies will be given with respect to any of the Shares.

This proxy will terminate on the Proxy Expiration Date (as defined in the Support Agreement). Capitalized terms not defined in this Proxy or in the Support Agreement shall have the respective meanings assigned to those terms in the Merger Agreement.

The attorneys and proxies named above will be empowered, and may exercise this proxy, to vote the Shares at any time until (and including) the Proxy Expiration Date at any meeting of the stockholders of the Company, however called, and in connection with any action by written consent of stockholders of the Company:

(i) in favor of (A) each of the actions contemplated by the Merger Agreement and (B) any action in furtherance of any of the foregoing;

(ii) against any action or agreement that would result in a breach of any representation, warranty, covenant or obligation of the Company in the Merger Agreement; and

(iii) against the following actions (other than the Transactions): (i) any Takeover Proposal (provided, that for the purposes of this clause “(i)” all references to “`15%” in the definition of Takeover Proposal shall be deemed to be references to “80%”); (ii) any amendment to the Company’s certificate of incorporation or bylaws; (iii) any material change in the capitalization of the Company or the Company’s corporate structure; and (iv) any other action which is intended or could reasonably be expected to prevent, impede, interfere with, delay, postpone, discourage or adversely affect any of the Transactions or this Agreement.

The Stockholder may vote the Shares on all other matters not referred to in this proxy, and the attorneys and proxies named above may not exercise this proxy with respect to such other matters.

This proxy shall be binding upon the heirs, estate, executors, personal representatives, successors and assigns of the Stockholder (including any transferee of any of the Shares).

Any term or provision of this proxy that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the Stockholder agrees 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 this proxy shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Stockholder agrees to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.
