2. Agreement to Retain Subject Securities.

(a) Transfer and Encumbrance of Subject Securities. Other than a Permitted Transfer, hereafter until the Expiration Time, each Company Stockholder agrees that it shall not, with respect to any Subject Securities Beneficially Owned by such Company Stockholder, (a) Transfer any such Subject Securities, or (b) deposit any such Subject Securities into a voting trust or enter into a voting agreement or arrangement with respect to such Subject Securities or grant any proxy (except as otherwise provided herein or to grant a revocable proxy to the Company’s proxy holders to vote or cause to be voted the Subject Securities in accordance with this Agreement) or power of attorney with respect thereto.

Notwithstanding anything to the contrary in this Agreement, if at any time following the date hereof and prior to the Expiration Time a Governmental Entity of competent jurisdiction enters an order restraining, enjoining, or otherwise prohibiting the Company Stockholders or their Affiliates from (a) consummating the transactions contemplated by the Merger Agreement or (b) taking any action pursuant to Section 3 or Section 4, then (i) the obligations of each Company Stockholder set forth in Section 3 and the irrevocable proxy and power of attorney in Section 4 shall be of no force and effect for so long as such order is in effect and, in the case of clause (b), solely to the extent such order restrains, enjoins, or otherwise prohibits such Company Stockholder from taking any such action, and (ii) for so long as such order is in effect, each Company Stockholder shall cause the Subject Securities to not be represented in person or by proxy at any meeting at which a vote of such Company Stockholder on the Merger is requested. Notwithstanding anything to the contrary in this Section 2(b), the restrictions set forth in Section 2(a) shall continue to apply with respect to the Subject Securities until the Expiration Time.

(c) Additional Purchases; Adjustments. Each Company Stockholder agrees that any shares of Company Common Stock and any other shares of capital stock or other equity of the Company that such Company Stockholder purchases or otherwise acquires (including pursuant to a stock split, reverse stock split, stock dividend or distribution or any change in Company Common Stock by reason of a merger, reorganization, recapitalization, reclassification, combination, exchange of shares, or similar transaction) or with respect to which such Company Stockholder otherwise acquires voting power after the execution of this Agreement and prior to the Expiration Time (the “New Company Common Stock”) shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted the Company Common Stock, and such Company Stockholder shall promptly notify Parent of the existence of any New Company Common Stock.

(ii) at any meeting of the stockholders of the Company called with respect to any of the following matters, and at every adjournment or postponement thereof, each Company Stockholder (A) shall appear at each such meeting or otherwise cause the Subject Securities that the Company Stockholder Beneficially Owns to be counted as present thereat for purposes of establishing a quorum and (B) shall, and shall cause each holder of record on any applicable record date to (including via proxy), vote all of the Subject Securities the Company Stockholder Beneficially Owns in favor of (1) the adoption of the Merger Agreement and the approval of the Merger, the other transactions contemplated in the Merger Agreement and any actions related to the Merger Agreement and (2) any proposal to adjourn or postpone such meeting of stockholders of the Company to a later date if there are not sufficient votes to adopt the Merger Agreement;

4

(iv) take such actions as may reasonably be requested by the Company or Parent in order to cause the Merger to constitute a Drag Transaction (as defined in the Company Stockholders Agreement).

(b) Change of Recommendation.

4. Irrevocable Proxy. By execution of this Agreement, each Company Stockholder hereby appoints and constitutes Parent, until the Expiration Time (at which time this proxy shall automatically be revoked), with full power of substitution and resubstitution, as such Company Stockholder’s true and lawful attorney-in-fact and proxy (which proxy is irrevocable and is coupled with an interest, pursuant to Section 212(e) of the DGCL), to the fullest extent of such Company Stockholder’s rights with respect to the Subject Securities Beneficially Owned by such Company Stockholder, to vote (or exercise a written consent with respect to) such Subject Securities solely with respect to the matters set forth in Section 3 hereof and each Company Stockholder shall retain the authority to vote its Subject Securities on all other matters; provided, however, that the foregoing shall only be effective if such Company Stockholder fails to be counted as present, to consent, or to vote such Company Stockholder’s Subject Securities, as applicable, in accordance with this Agreement; provided, further, however, that if at any time from and after the date hereof until the Expiration Time there occurs a Change of Recommendation Event, then the irrevocable proxy contemplated by this Section 4 shall terminate and cease to be effective with respect to all Subject Securities other than the Covered Securities.

5. Representations and Warranties of the Company Stockholders. Each Company Stockholder hereby severally, but not jointly, represents and warrants to each of Parent and the Company as follows:

(ii) No consent, approval, order, or authorization of, or registration, declaration, or filing with, any Governmental Entity or any other Person, is required by or with respect to such Company Stockholder or an Affiliate in connection with the execution and delivery of this Agreement or the performance by such Company Stockholder of its obligations hereunder.

(d) Absence of Litigation. There is no Proceeding pending against, or, to the knowledge of such Company Stockholder, threatened against or affecting, such Company Stockholder or an Affiliate that could reasonably be expected to materially impair or materially adversely affect the ability of such Company Stockholder to perform such Company Stockholder’s obligations hereunder on a timely basis.

6. Termination. This Agreement shall terminate immediately at, and shall have no further force or effect as of and following, the Expiration Time, provided, however, that the termination of this Agreement shall not relieve any Party from any liability for any inaccuracy in or breach of any representation, warranty, or covenant contained in this Agreement.

6

7. Notice of Certain Events. Each Company Stockholder shall notify Parent and the Company in writing promptly of (a) any fact, event, or circumstance that would cause, or reasonably be expected to cause or constitute, a breach in any material respect of the representations and warranties of such Company Stockholder under this Agreement and (b) the receipt by such Company Stockholder of any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with this Agreement; provided, however, that the delivery of any notice pursuant to this Section 7 shall not limit or otherwise affect the remedies available to any Party.

10. Miscellaneous.

(a) Severability. 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 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

7

and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Parties 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.

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. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by applicable Law.

Each Company Stockholder agrees to promptly give Parent and the Company any information they may reasonably require for the preparation of any such disclosure documents, and such Company Stockholder agrees to promptly notify Parent and the Company of any required corrections with respect to any written information supplied by such Company Stockholder specifically for use in any such disclosure document, if and to the extent that any such information shall have become false or misleading in any material respect. Parent and the Company shall in any instance where such Company Stockholder or information relating thereto is disclosed, use their respective reasonable best efforts to provide drafts of such disclosures with sufficient time to enable such Company Stockholder to review and provide comments on such disclosures and Parent and Company shall in good faith consider incorporating any reasonable modifications requested by such Company Stockholder.

(p) Obligation to Update Schedule A. Each of the Company Stockholders agrees that in connection with any acquisitions or Transfers (to the extent permitted) of Subject Securities by such Company Stockholder, such Company Stockholder will, as promptly as practicable following the completion thereof, notify Parent and the Company in writing of such acquisition or Transfer and the Parties will update Schedule A to reflect the effect of such acquisition or Transfer.
