or to make such filings or notifications, could not prevent or materially delay the performance by Stockholder of Stockholder’s obligations under this Agreement. Stockholder does not have any arrangement in effect that is binding on Stockholder with respect to the voting or transfer of any Shares. Stockholder is not required to make any filing with or notify any governmental or regulatory authority in connection with this Agreement, the Merger Agreement or the transactions contemplated hereby or thereby pursuant to the requirements of the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended, and the rules and regulations promulgated thereunder (the “HSR Act”).

SECTION 2.03 Title to Shares. Except for any Shares that were the subject of a Transfer in compliance with Section 1.01 hereof, Stockholder is the record or beneficial owner of the Shares free and clear of all encumbrances, proxies or voting restrictions other than pursuant to this Agreement.

SECTION 4.02 Legending of Shares. If so requested by Parent, Stockholder agrees that the Shares shall bear a legend stating that they are subject to this Agreement and to the Proxy. Stockholder agrees that Stockholder

Subject to the terms of Section 1.01 hereof, Stockholder agrees that Stockholder shall not Transfer any of the Shares without first having the aforementioned legend affixed to the certificates representing such Shares.

SECTION 4.04 Additional Shares. In the event that Stockholder acquires any additional Shares, such Shares shall, without further action of the parties, be subject to the provisions of this Agreement and the Proxy, and the number of Shares set forth on the signature page hereto and thereto will be deemed amended accordingly. If Stockholder acquires additional Shares, Stockholder shall promptly notify Parent in writing of such acquisition.

SECTION 5.01 Entire Agreement. This Agreement and the Proxy constitute the entire agreement of the parties and supersede all prior agreements and undertakings, both written and oral, between the parties, or any of them, with respect to the subject matter hereof. This Agreement may not be amended or modified except in an instrument in writing signed by, or on behalf of, the parties hereto.

SECTION 5.02 Survival of Representations and Warranties. All representations and warranties made by Stockholder in this Agreement shall survive any termination of the Merger Agreement or this Agreement.

SECTION 5.03 Assignment. 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 that any assignment, delegation or attempted transfer of any rights, interests or obligations under this Agreement by either party hereto without the prior written consent of the other party hereto shall be void.

SECTION 5.04 Fees and Expenses. Except as otherwise provided herein, all costs and expenses (including, without limitation, all fees and disbursements of counsel, accountants, investment bankers, experts and consultants to a party) incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs and expenses.

All notices and other communications given or made pursuant hereto shall be in writing and shall be deemed effectively given: (i) upon personal delivery to the party to be notified, (ii) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient; if not, then on the next business day, (iii) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (iv) one (1) day after deposit with a nationally recognized overnight courier,

specifying next day delivery, with written verification of receipt. All communications shall be sent to the respective parties at the following addresses (or at such other addresses as shall be specified by notice given in accordance with this Section 5.05):

SECTION 5.06 Headings. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

SECTION 5.07 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any 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 hereby is not affected in any manner materially 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 to the fullest extent permitted by applicable law in an acceptable manner.

SECTION 5.08 Specific Performance. The parties agree that irreparable damage would occur if any of the provisions of this Agreement is not performed in accordance with its specific terms or is otherwise breached. Stockholder agrees that, following any breach or threatened breach by Stockholder of any covenant or obligation

contained in this Agreement, Parent shall be entitled (in addition to any other remedy that may be available to it, including monetary damages) to seek and obtain (a) a decree or order of specific performance to enforce the observance and performance of such covenant or obligation and (b) an injunction restraining such breach or threatened breach. Stockholder further agrees that neither Parent nor any other party 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 5.08, and Stockholder irrevocably waives any right he may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

SECTION 5.09 Governing Law. This Agreement shall be construed in accordance with, and governed in all respects by, the laws of the State of Delaware, without giving effect to principles of conflicts of laws. Each party hereby irrevocably submits to the exclusive jurisdiction of the Court of Chancery in the State of Delaware in any action, suit or proceeding arising in connection with this Agreement, and agrees that any such action, suit or proceeding shall be brought only in such court (and waives any objection based on forum non conveniens or any other objection to venue therein); provided, however, that such consent to jurisdiction is solely for the purpose referred to in this Section 5.09 and shall not be deemed to be a general submission to the jurisdiction of such court or in the State of Delaware other than for such purposes.

SECTION 5.10 No Waiver. 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. Parent shall not be deemed to have waived any claim available to it arising out of this Agreement, or any right, power or privilege hereunder, unless the waiver is expressly set forth in writing duly executed and delivered on behalf of Parent. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

SECTION 5.11 Counterparts. This Agreement may be executed in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

IN WITNESS WHEREOF, each of Parent and Stockholder has executed or has caused this Agreement to be executed by their duly authorized officer as of the date first written above.
