(ii) against (A) any Acquisition Proposal, (B) any proposal for any recapitalization, reorganization, liquidation, dissolution, amalgamation, merger, sale of assets or other business combination between the Company and any other Person (other than the Merger), (C) any other action that would result in impeding, interfering with, delaying, postponing, discouraging or adversely affecting the consummation of the Merger or any of the transactions contemplated by the Merger Agreement or this Agreement or any transaction that results in a breach in any material respect of any covenant, representation or warranty or other obligation or agreement of the Company under the Merger Agreement, and (D) any resolution, agreement or proposal to solicit, initiate, endorse, encourage, facilitate, enter into, or otherwise participate in any discussions or negotiations with any Person regarding any of the foregoing items specified in this clause (ii).

2. Grant of Irrevocable Proxy; Appointment of Proxy.

(a) EACH STOCKHOLDER HEREBY GRANTS TO AND APPOINTS PARENT, THE EXECUTIVE OFFICERS OF PARENT, AND ANY OTHER DESIGNEE OF PARENT, AND EACH OF THEM INDIVIDUALLY, SUCH STOCKHOLDER'S IRREVOCABLE (UNTIL THE TERMINATION DATE) PROXY AND ATTORNEY-IN-FACT (WITH FULL POWER OF SUBSTITUTION) TO (I) ATTEND ANY AND ALL MEETINGS OF THE COMPANY'S STOCKHOLDERS, (II) VOTE, OR ISSUE INSTRUCTIONS TO THE RECORD HOLDER TO VOTE, THE COVERED SHARES OWNED AT THE TIME OF THE RECORD DATE FOR SUCH MEETING AS INDICATED IN SECTION 1 AT ANY AND ALL MEETINGS OF THE COMPANY'S STOCKHOLDERS AND (III) GRANT OR WITHHOLD, OR ISSUE INSTRUCTIONS TO THE RECORD HOLDER TO GRANT OR WITHHOLD, IN ACCORDANCE WITH THE PROVISIONS OF SECTION 1, ALL WRITTEN CONSENTS WITH RESPECT TO THE COVERED SHARES OWNED AT THE TIME OF SUCH WRITTEN CONSENT AT ANY AND ALL MEETINGS OF THE COMPANY'S STOCKHOLDERS.

3. No Inconsistent Agreements. Each Stockholder hereby covenants, represents, warrants and agrees that, except as contemplated by this Agreement, such Stockholder (a) has not entered into or deposited any Covered Shares under, and shall not enter into or deposit any Covered Shares under, at any time prior to the Termination Date, any voting agreement or voting trust with respect to any Covered Shares; and (b) has not granted, and shall not grant, at any time prior to the Termination Date, a proxy or power of attorney with respect to any Covered Shares, except for a proxy designated by the Company that will vote in favor of the Merger, the approval of the Merger Agreement, and any other matters necessary for consummation of the Merger and the other transactions contemplated in the Merger Agreement.

7. Representations and Warranties of Stockholders. Each Stockholder, as to itself, hereby represents and warrants to Parent, as of the date of this Agreement and as of the record date for each meeting of stockholders of the Company occurring prior to the Termination Date, as follows:

(a) If an entity, such Stockholder is duly organized, validly existing and in good standing under the laws of the jurisdiction of its formation and has all requisite power and authority to execute and deliver this Agreement and to perform its obligations hereunder; or, if a natural person, such Stockholder has full legal power and capacity to execute and deliver this Agreement and to perform such Stockholder's obligations hereunder.

(b) There is no action, suit, investigation, complaint or other proceeding pending against any such Stockholder or, to the knowledge of such Stockholder, any other Person or, to the knowledge of such Stockholder, threatened against any Stockholder or any other Person that restricts or prohibits (or, if successful, would restrict or prohibit) the exercise by Parent of its rights under this Agreement or the performance by any party of its obligations under this Agreement.

(c) Each Stockholder understands and acknowledges that Parent is entering into the Merger Agreement in reliance upon such Stockholder's execution and delivery of this Agreement and the representations and warranties of such Stockholder contained herein. Such Stockholder has had the opportunity to review the Merger Agreement and this Agreement with counsel of his, her or its own choosing.

8. Stockholder Capacity. No stockholder makes any agreement or undertaking in this Agreement in such Stockholder’s capacity as a director or officer of the Company or any of its subsidiaries (if such Stockholder holds such office), and nothing in this Agreement: (a) will limit or affect any actions taken or not taken by such Stockholder in such stockholder’s capacity as such a director or officer, including in exercising rights under the Merger Agreement, and no such actions or omissions shall be deemed a breach of this Agreement or (b) will be construed to prohibit, limit or restrict any Stockholder from exercising such Stockholder’s fiduciary duties as an officer or director to the Company or its stockholders.

9. Disclosure. Each Stockholder: (i) hereby authorizes Parent, Newco and the Company to publish and disclose in any announcement, in any disclosure required by the SEC or applicable Law, and in the Proxy Statement, such Stockholder's identity and ownership of the Covered Shares and the existence of this Agreement and the nature of such Stockholder's obligations hereunder; (ii) shall promptly give to Parent, Newco and the Company any information that any of them may require for the preparation of any such announcement or disclosure document; and (iii) shall promptly notify Parent, Newco and the Company of any inaccuracies or omissions with respect to any information supplied by such Stockholder to Parent, Newco or the Company.

11. Non-Survival of Representations and Warranties. The representations, warranties and covenants of the Stockholders contained herein shall not survive the closing of the transactions contemplated by the Merger Agreement.

12. Amendment and Modification. This Agreement may not be amended, modified, or supplemented in any manner, whether by course of conduct or otherwise, except by an instrument in writing signed on behalf of each party, or otherwise as expressly set forth herein.

13. Waiver. No failure or delay of any party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights or remedies which they would otherwise have hereunder. Any agreement on the part of a party to any such waiver shall be valid only if set forth in a written instrument executed and delivered by such party.
