AGREEMENT

NOW, THEREFORE, in consideration of the mutual covenants and promises contained in this Agreement and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties to this Agreement agree as follows:

1. Certain Definitions. All capitalized terms that are used but not defined herein shall have the respective meanings ascribed to them in the Merger Agreement. For all purposes of and under this Agreement, the following terms shall have the following respective meanings:

2. Transfer of Subject Shares.

(a) Transfer Restrictions. Except as expressly contemplated by this Agreement or the Merger Agreement, the Stockholder shall not cause or voluntarily consent to any Transfer of any of the Subject Shares to be effected.

(b) Transfer of Voting Rights. The Stockholder shall not (i) deposit any Subject Shares in a voting trust or grant any proxy or power of attorney or enter into any voting agreement or similar agreement with respect to any of the Subject Shares or (ii) take (or knowingly refrain from taking) any other action that would in any way restrict, limit or interfere with the performance of the Stockholder’s obligations hereunder or otherwise make any representation or warranty of the Stockholder herein untrue or incorrect. Any action taken in violation of the foregoing sentence shall be null and void ab initio and such Stockholder agrees that any such prohibited action may and should be enjoined.

(c) Exceptions. Nothing in this Section 2 shall prohibit a Transfer of Subject Shares by Stockholder: (i) if Stockholder is an individual, pursuant to applicable laws of descent and distribution; (ii) if Stockholder is a partnership, corporation, limited liability company or trust, to one or more partners, shareholders or members of Stockholder or to an affiliated entity under common control with Stockholder or to any trustee or beneficiary of the trust; or (iii) if Stockholder is a trust, to distribute up to [•] shares to its beneficiaries pursuant to the withdrawal rights of beneficiaries; provided, however, that a Transfer referred to in Section 2(c)(i) or (ii) hereof shall be permitted only if the transferee agrees in writing, reasonably satisfactory in form and substance to Parent, to be bound by the terms of this Agreement.

(d) Involuntary Transfer. If any involuntary Transfer of any of the Subject Shares shall occur (including, but not limited to, a sale by the Stockholder’s trustee in any bankruptcy, or a sale to a purchaser at any creditor’s or court sale), the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and hold such Subject Shares subject to all of the restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect until valid termination of this Agreement.

3. Agreement to Tender.

(a) Tender of Shares. The Stockholder shall tender, pursuant to and in accordance with the terms of the Offer, the Subject Shares. No later than five (5) business days after commencement of the Offer, the Stockholder shall (a) deliver to the depositary designated in the Offer all documents or instruments required to be delivered in order to tender the Subject Shares pursuant to the terms of the Offer, and/or (b) instruct its broker or such other person who is the holder of record of any Subject Shares to tender such shares for exchange in the Offer pursuant to the terms and conditions of the Offer. Prior to the Expiration Date, the Stockholder shall not tender the Subject Shares into any exchange or tender offer commenced by a third party other than Parent or Merger Sub. Notwithstanding anything to the contrary herein, the Stockholder may withdraw such Subject Shares from the Offer at any time following the termination of this Agreement. For the avoidance of doubt, (x) the Stockholder shall not be required, for purposes of this Agreement, to exercise any unexercised Company equity award

3

held by the Stockholder and (y) the Stockholder shall not have any obligation under this Section 3 to tender (or caused to be tendered) any Subject Shares into the Offer to the extent such tender could cause the Stockholder to incur liability under Section 16(b) of the Exchange Act.

(b) Return of Shares. If the Offer is terminated or withdrawn by Merger Sub or the Merger Agreement is terminated prior to the purchase of Subject Shares in the Offer, Parent and Merger Sub shall promptly return, and shall cause any depository or paying agent, acting on behalf of Parent and Merger Sub, to promptly return all tendered Subject Shares to the Stockholder.

4. Directors and Officers. Notwithstanding any provision of this Agreement to the contrary, nothing in this Agreement shall (or shall require the Stockholder to attempt to) limit or restrict the Stockholder in his or her capacity as a director or officer of the Company or any designee of the Stockholder who is a director or officer of the Company from acting in such capacity or voting in such person’s sole discretion on any matter (it being understood that this Agreement shall apply to the Stockholder solely in the Stockholder’s capacity as a stockholder of the Company and that any director or officer of the Company who signs this Agreement on behalf of the Stockholder is signing only as an individual and not in any other capacity). No action (or inaction) taken by the Stockholder in their capacity as a director or officer of the Company shall be deemed to constitute a breach of this Agreement.

5. Trustees. Notwithstanding any provision of this Agreement to the contrary, nothing in this Agreement shall (or shall require the Stockholder to attempt to) limit or restrict any trustee of the Stockholder in his or her capacity as a director or officer of the Company from acting in such capacity or voting in such person’s sole discretion on any matter (it being understood that this Agreement shall apply to the Stockholder solely in the Stockholder’s capacity as a stockholder of the Company and that any trustee who signs this Agreement on behalf of the Stockholder is signing only in his or her capacity as a trustee and not as an individual or in any other capacity). No action (or inaction) taken by any trustee in their capacity as a director or officer of the Company shall be deemed to constitute a breach of this Agreement.

6. No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent or Merger Sub any direct or indirect ownership or incidence of ownership of or with respect to any Subject Shares. All rights, ownership and economic benefits of and relating to the Subject Shares shall remain vested in and belong to the Stockholder, and neither Parent nor Merger Sub shall have the authority by virtue of this Agreement or the transactions to be consummated pursuant hereto to manage, direct, superintend, restrict, regulate, govern, or administer any of the policies or operations of the Company or exercise any power or authority to direct the Stockholder in the voting of any of the Subject Shares to the extent such Subject Shares are entitled to be voted, except as otherwise provided herein.

Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement 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 of this Agreement is invalid or unenforceable, the parties hereto agree 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 Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree 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.
