(b) Each Stockholder shall not commit or agree to take any action inconsistent with any provision of Section 3.01(a).

SECTION 3.02. Irrevocable Proxy. Each Stockholder hereby irrevocably grants to, and appoints, the Company, and any individual designated in writing by the Company, and each of them individually, as such Stockholder’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of such Stockholder, to vote its Subject Shares, or grant a consent or approval in respect of its Subject Shares, in a manner consistent with Section 3.01 if such Stockholder has not voted such Subject Shares in a manner consistent with Section 3.01 at least five (5) Business Days prior to the applicable voting deadline. Each Stockholder understands and acknowledges that the Company is entering into the Merger Agreement in reliance upon such Stockholder’s execution and delivery of this Agreement. Each Stockholder hereby affirms that the irrevocable proxy set forth in this Section 3.02 is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Stockholder under this Agreement. Each Stockholder hereby further affirms that the irrevocable proxy set forth in this Section 3.02 is coupled with an interest and may under no circumstances be revoked. Each Stockholder hereby ratifies and confirms all that such irrevocable proxy may lawfully do or cause to be done by virtue hereof. Such irrevocable proxy is executed and intended to be irrevocable in accordance with the provisions of Section 212(e) of the DGCL. Notwithstanding the foregoing, the proxy and appointment granted hereby shall be automatically revoked, without any action by any Stockholder, upon any termination of this Agreement pursuant to Section 4.11.

SECTION 3.03. Transfer and Other Restrictions. Except pursuant to this Agreement, each Stockholder shall not, directly or indirectly, (i) sell, transfer, pledge, assign or otherwise dispose of (including by gift, merger or otherwise by operation of law) (collectively, “Transfer”), or enter into any Contract, option or other arrangement or understanding (excluding any profit sharing agreement or any other arrangement that constitutes a Transfer of the economic (but not the voting) interest in such Subject Shares) with respect to the Transfer of, any of its Subject Shares to any Person, (ii) enter into any voting arrangement, whether by proxy, voting agreement or otherwise, with respect to any of its Subject Shares, (iii) take any other action that would make any representation or warranty of such Stockholder contained herein untrue or

5

incorrect or would in any way restrict, limit or interfere with the performance of such Stockholder’s obligations hereunder or (iv) commit or agree to take any of the foregoing actions; provided, however, that the foregoing restrictions on Transfer will not be applicable to, and the Stockholder will not be restricted or prohibited from taking, any of the following actions with respect to the Subject Shares (and the taking of such actions will not constitute a breach of this Agreement): (A) a bona fide pledge of, or grant of a security interest in, Subject Shares in connection with any financing arrangements with a financial institution that is in the business of engaging in such transactions, including any resulting Transfer of such pledged shares (or shares in which a security interest has been granted) upon any foreclosure under the indebtedness underlying such pledge or security interest; (B) any Transfer of Subject Shares to an Affiliate of such Stockholder so long as such Affiliate executes an instrument assuming all the rights, benefits and obligations of such Stockholder hereunder and (C) any Transfer of up to twenty percent (20%) of the Subject Shares as of the date of this Agreement so long as, unless such Transfer is consummated pursuant to an open market sale or in an SEC registered underwritten public offering, the transferee of such Subject Shares executes an instrument assuming all the rights, benefits and obligations of the Stockholder hereunder. Each Stockholder hereby authorizes and will instruct Parent or its counsel to notify Parent’s transfer agent that there is a stop transfer order with respect to all of the Subject Shares of such Stockholder (and that this Agreement places limits on the voting and transfer of such Subject Shares), subject to the provisions hereof. Notwithstanding the foregoing, any such stop transfer order and notice will immediately be withdrawn and terminated upon any termination of this Agreement pursuant to Section 4.11.

SECTION 3.04. Non-Solicitation. Each Stockholder shall not, and shall not permit any of its controlled Affiliates or any of their respective Representatives to, directly or indirectly, (i) solicit, initiate or knowingly encourage, or take any other action to knowingly facilitate, the making of any proposal that constitutes or is reasonably likely to lead to a Parent Acquisition Proposal or (ii) enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any Person any confidential information with respect to, any Parent Acquisition Proposal. Each Stockholder shall, and shall cause its controlled Affiliates and direct its and their respective Representatives to, immediately cease and cause to be terminated all existing discussions and negotiations with any Person conducted heretofore with respect to any Parent Acquisition Proposal. Notwithstanding the foregoing, at any time prior to obtaining the Parent Stockholder Approval, a Stockholder may (and may authorize and permit its controlled Affiliates and its and their respective Representatives to) furnish such information to, and participate in such discussions and negotiations with, a Person (other than such Stockholder or any of its controlled Affiliates) making a Parent Acquisition Proposal (and its Representatives) to the same extent that Parent is permitted to do so pursuant to, and in accordance with, Section 7.3 of the Merger Agreement. In the event that, pursuant to the foregoing sentence, any Stockholder or any of their respective controlled Affiliates or any of their respective Representatives furnishes to a Person making a Parent Acquisition Proposal (or its Representatives) any non-public information that has not previously been furnished to the special committee of the board of directors of the Company (the “Special Committee”) or its Representatives, such Stockholder shall furnish all such information to the Special Committee substantially concurrently with the time it is provided to such Person. Each Stockholder shall, as promptly as practicable, advise the Special Committee orally and in writing of the receipt of any Parent Acquisition Proposal after the date hereof, the material terms and conditions of any such Parent Acquisition Proposal and the identity of the Person making any such Parent Acquisition Proposal. Each Stockholder shall keep the Special Committee reasonably informed of any material developments with respect to any such Parent Acquisition Proposal (including any material changes thereto).

SECTION 3.05. Directors and Officers. Notwithstanding any provision of this Agreement to the contrary, nothing in this Agreement shall limit or restrict any Stockholder (or a designee of any Stockholder) who is a director or officer of Parent or the Company from acting in such capacity or fulfilling the obligations of such office (including, for the avoidance of doubt, exercising their fiduciary duties), including by voting, in their capacity as a director or officer of Parent or the Company, in such Stockholder’s (or its designee’s) sole discretion on any matter (it being understood that this Agreement shall apply to each Stockholder solely in such Stockholder’s capacity as a stockholder of Parent or the Company), including with respect to Section 7.2 or Section 7.3 of the Merger Agreement. In this regard, each Stockholder shall not be deemed to make any agreement or understanding in this Agreement in such Stockholder’s capacity as a director or officer of Parent or the Company, including with respect to Section 7.2 or Section 7.3 of the Merger Agreement.

SECTION 3.06. Public Announcements. Each Stockholder shall, and shall cause its controlled Affiliates to, consult with the Special Committee prior to issuing any press release or otherwise making public announcements, disclosures or communications issued by such Stockholder or its controlled Affiliates with respect to this Agreement, the Merger Agreement, the Parent Share Issuance or any of the other transactions contemplated by the Merger Agreement, and shall not issue any such press release or make any such press release, public announcement, disclosure or communication prior to such consultation, except as may be required by applicable Law or by obligations pursuant to any listing agreement with or rules of any national securities exchange or interdealer quotation service or by the request of any Governmental Entity, in which case the Person making the disclosure shall give the Special Committee reasonable opportunity to review and comment upon such disclosure or communication to the extent reasonably practicable and legally permitted; provided that, with respect to any Stockholder that is a partnership, the foregoing shall not restrict any communications between such Stockholder and its or its Affiliates’ direct or indirect limited partners; provided that such communications do not contain any material non-public information and do not include any statements that could reasonably be construed as critical or adverse to the Mergers, the Parent Share Issuance or the other transactions contemplated by the Merger Agreement or this Agreement or that would constitute a Change of Parent Recommendation if made by the Parent Board or any committee of the Parent Board. Notwithstanding the foregoing, each Stockholder hereby agrees to permit Parent and the Company to publish and disclose in the Joint Proxy Statement (including all documents filed with the SEC in accordance therewith), such Stockholder’s identity and beneficial ownership of the Subject Shares or other equity interests of Parent and the nature of such Stockholder’s commitments, arrangements and understandings under this Agreement.
