Section 5.03                             Communications.  Such Stockholder hereby (i) consents to and authorizes the publication and disclosure by Parent, Merger Sub and the Company (including in the Offer Documents, the Schedule 14D-9 or any other publicly filed document relating to the Transactions) of (a) such Stockholder’s identity, (b) such Stockholder’s Beneficial Ownership of shares of Company Common Stock or Company Stock Options (including the number of such shares or Company Stock Options Beneficially Owned by Stockholder) and (c) the nature of such

5

Stockholder’s commitments, arrangements and understandings under this Agreement, and any other information that Parent, Merger Sub or the Company reasonably determines to be required in any publicly filed document in connection with the Transactions, and (ii) agrees as promptly as practicable to notify Parent, Merger Sub and the Company of any required corrections with respect to any written information supplied by such Stockholder specifically for use in any such disclosure document.

Section 5.05.  Waiver of Appraisal and Dissenters’ Rights and Actions.  Such Stockholder hereby (i) waives and agrees not to exercise any rights (including under Section 262 of the General Corporation Law of the State of Delaware) to demand appraisal of any Covered Shares or rights to dissent from the Merger which may arise with respect to the Merger and (ii) agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or other Proceeding, against Parent, Merger Sub, the Company or any of their respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the making or consummation of the Offer or consummation of the Merger, including any Proceeding (x) challenging the validity of, or seeking to enjoin the operation of, any provision of this Agreement or (y) alleging a breach of any fiduciary duty of the Company Board in connection with the Transactions.

Section 6.02.  Further Assurances.  Parent, Merger Sub and each Stockholder (in its capacity as such) will each execute and deliver, or cause to be executed and delivered, all further documents and instruments as the other may reasonably request and use reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary and all things the other party may reasonably deem proper or advisable under applicable Law, to consummate and make effective the transactions contemplated by this Agreement.  Without limiting the generality of the foregoing, each Stockholder shall, to the extent requested by Parent or Merger Sub, promptly cause each other Person having voting power with respect to any Covered Shares to execute and deliver to Parent or Merger Sub a proxy with respect to such shares, which shall be identical to the proxy in Section 2.02.

Section 6.03.  Amendments; Termination.  Any provision of this Agreement may be amended if, and only if, such amendment is in writing and is signed by each party to this Agreement.  This Agreement shall automatically terminate upon the termination of the Support Period; provided, however, that no termination of this Agreement shall relieve any party hereto from any liability for any breach of any provision of this Agreement prior to such termination.

Section 6.04.  Expenses.  All costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such cost or expense.

Section 6.05.  Successors and Assigns.  The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns; provided, however, that Stockholder may not assign, delegate or otherwise transfer any of

7

Stockholder’s rights or obligations under this Agreement without the prior written consent of Parent.  Any assignment, delegation or transfer in violation of the foregoing shall be null and void.

Section 6.06.  Governing Law.  This Agreement and any Proceedings arising out of or related hereto or the Transactions or to the inducement of any party thereto to enter into this Agreement, (whether for breach of contract, tortious conduct or otherwise and whether predicated on common law statute or otherwise) shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflicts of law rules of such state.

Section 6.07.  Counterparts; Effectiveness.  This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in PDF form, or by any other electronic means designed to preserve the original graphic and pictorial appearance of a document, will be deemed to have the same effect as physical delivery of the paper document bearing the original signatures. This Agreement shall become effective when each party hereto shall have received counterparts hereof signed by all of the other parties hereto and the Merger Agreement has become effective. Until and unless each party has received a counterpart hereof signed by the other parties hereto and the Merger Agreement has become effective, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication).

Section 6.08.  Severability.  If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto. Upon such a determination, 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 an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 6.09.  Specific Performance.  The parties hereto agree that irreparable damage to Parent and Merger Sub would occur, damages would be incalculable and would be an insufficient remedy and no other adequate remedy would exist at law or in equity, in each case in the event that any provision of this Agreement were not performed by Stockholder in accordance with the terms hereof, and that each of Parent and Merger Sub shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically Stockholder’s performance of the terms and provisions hereof, in addition to any other remedy to which Parent or Merger Sub may be entitled at law or in equity.  Stockholder hereby waives any defenses based on the adequacy of any other remedy, whether at law or in equity, that might be asserted as a bar to the remedy of specific performance of any of the terms or provisions hereof or injunctive relief in any action brought therefor by Parent or Merger Sub. Stockholder further agrees that neither Parent nor any other Person shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 6.09, and Stockholder irrevocably

8

waives any right Stockholder may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

(i)                           Capitalized terms used but not defined herein shall have the respective meanings set forth in the Merger Agreement.
