NOW, THEREFORE, in consideration of the foregoing, the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

ARTICLE I

TENDER OF THE COVERED SECURITIES

Section 1.1 Tender of the Covered Securities. This Section 1.1 shall have no force or effect and shall not be binding on the parties until the earlier of (i) the expiration of the Lock-Up Period (as defined in the letter agreement, dated January 20, 2012, by the Stockholder to Merrill Lynch, Pierce, Fenner & Smith Incorporated and Goldman, Sachs & Co. (the “Lock-Up Agreement”)) in accordance with the Lock-Up Agreement or (ii) the effectiveness of a waiver of or amendment (the “Lock-Up Waiver”) to the Lock-Up Agreement expressly permitting the Stockholder to take the actions contemplated by this Agreement (such earlier date, the “Effective Date”). From and after the Effective Date, the Stockholder agrees to (i) tender the Covered Securities (or to cause the Covered Securities to be tendered) into the Offer, (ii) not withdraw the Covered Securities (or to not cause the Covered Securities to be withdrawn) from the Offer at any time (unless this Agreement is terminated in accordance with Article V hereof (the “Termination Date”)) and (iii) use reasonable best efforts to take all actions (or to cause all actions to be taken by its affiliates) necessary to effectuate the foregoing.

Notwithstanding anything in this Agreement to the contrary, nothing herein shall require the Stockholder or any of its affiliates to exercise any stock option or other equity award or require the Stockholder to purchase any shares of Common Stock. If the Offer is terminated or withdrawn by Parent or Merger Sub, or the Merger Agreement is terminated prior to the purchase of the Covered Securities tendered in the Offer, Parent and Merger Sub shall promptly return, and shall cause any depository or paying agent acting on behalf of Parent or Merger Sub to return, as soon as practicable (and in any event in accordance with applicable law) all tendered Covered Securities to the Stockholder.

(ii) against approval of any proposal made in opposition to, or in competition with, consummation of the Offer or the Merger and the transactions contemplated by the Merger Agreement; and

Notwithstanding the foregoing, no failure or delay by any party in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

Section 6.4 Assignment; Binding Effect. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties. Except as expressly set forth in Section 1.1 or Section 2.2, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns. Parent shall cause Merger Sub, and any permitted assignee thereof, to perform its obligations under this Agreement and shall be responsible for any failure of Merger Sub or such assignee to comply with any representation, warranty, covenant or other provision of this Agreement.

Section 6.7 Severability.

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 to the fullest extent permitted by applicable Law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible. If a court of competent jurisdiction determines that Section 1.1 or Section 2.2 (or any term or provision therein), or any other term or provision of this Agreement, conflicts

Each of the parties hereto hereby irrevocably and unconditionally consents to service of process in the manner provided for notices in Section 6.2 (Notices).

ADEQUATE REMEDY AT LAW 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 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 DELAWARE COURTS, THIS BEING IN ADDITION TO ANY OTHER REMEDY TO WHICH THEY ARE ENTITLED AT LAW OR IN EQUITY (AND EACH PARTY HERETO HEREBY WAIVES ANY REQUIREMENT FOR THE SECURING OR POSTING OF ANY BOND IN CONNECTION WITH SUCH REMEDY).

Section 6.12 Definitions; Interpretation. Capitalized terms used but not defined herein are used with the meanings given to them in the Merger Agreement (without giving effect to any amendment or modification thereto).

to manage, direct, restrict, regulate, govern, or administer any of the policies or operations of the Company or exercise any power or authority to direct Stockholder in the voting of any of the Covered Securities.
