RECITALS

WHEREAS, pursuant to and in accordance with the terms and conditions set forth in the Merger Agreement, the Company will issue Series A Preferred Stock, par value $0.0001 per share, of the Company (“Series A Preferred Stock”), to Stockholder in connection with the Merger (the “Preferred Consideration Shares”); and

WHEREAS, in connection with the Merger Agreement and effective upon the consummation of the Merger and the other transactions contemplated thereby, the parties hereto wish to set forth certain understandings between such parties, including with respect to certain governance and other matters of the Company.

NOW, THEREFORE, in consideration of the mutual representations, covenants and agreements contained herein, and certain other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as follows:

1. Election of Directors.

(a) From and after the Effective Time, Stockholder shall have the right, but not the obligation, to designate each director to be nominated, elected or appointed to the Board of Directors of the Company (each, a “Stockholder Designee” and collectively, the “Stockholder Designees”), regardless of (i) whether such Stockholder Designee is to be elected to the Board of Directors of the Company (the “Board”) at a meeting of stockholders called for the purpose of electing directors (or by consent in lieu of meeting) or appointed by the Board in order to fill any vacancy created by the departure of any director or increase in the authorized number of members of the Board or (ii) the size of the Board.

(b) For so long as Stockholder has the right under Section 1(a) to designate Stockholder Designees, the Company shall take all Necessary Action to cause each Stockholder Designee to be so nominated, elected or appointed to the Board, including (as applicable) (i) submitting each Stockholder Designee to the Company’s stockholders as the Company’s nominee

1

for election at a meeting of the Company’s stockholders, (ii) recommending that such Stockholder Designee be elected by the Company’s stockholders and (iii) soliciting proxies or consents in favor thereof. In the event that any Stockholder Designee shall fail to be elected or appointed to the Board pursuant to the preceding sentence, the Company shall (at the written request of Stockholder) take all Necessary Action to cause an alternative Stockholder Designee to be elected or appointed to the Board, as soon as possible. For so long as Stockholder has the right to designate Stockholder Designees pursuant to Section 1(a), Stockholder may, at any time and from time to time, designate a replacement director therefor, who shall be elected or appointed in accordance with Section 1 of this Agreement and who shall be deemed a “Stockholder Designee” for purposes of this Agreement.

(c) The parties hereto acknowledge and agree that the members of the Board are subject to removal pursuant to the applicable provisions of the General Corporation Law of the State of Delaware, the Certificate of Incorporation of the Company (as may be amended and/or amended and restated from time to time in accordance with the terms thereof, the “Company Certificate of Incorporation”), and the bylaws of the Company (as may be amended and/or amended and restated from time to time in accordance with the terms thereof, the “Company Bylaws”); provided, however, that the Company shall refrain from taking any actions to cause any Stockholder Designee to be removed without cause except with the written consent of Stockholder.

(d) Stockholder hereby agrees to vote in favor of and to consent to the Stockholder Designees in connection with each vote taken or written consent executed in connection with the election of directors to the Board.

(e) “Necessary Action” means, with respect to any party and a specified result, all actions (to the extent such actions are not prohibited by applicable Law and within such party’s control, and in the case of any action that requires a vote or other action on the part of the Board, to the extent such action is consistent with fiduciary duties that the Company’s directors may have in such capacity) necessary to cause such result, including (i) calling special meetings of stockholders, and (ii) nominating certain persons for election to the Board in connection with the annual or special meeting of stockholders of the Company.

2. Compensation. The Stockholder Designees shall be entitled to compensation pursuant to the Company’s director compensation policy, as such policy may be determined from time to time by the Board or compensation committee thereof.

3. Indemnification; Exculpation. The Stockholder Designees shall be entitled to indemnification, exculpation and reimbursement of fees and expenses to the extent provided for in the Company Certificate of Incorporation and the Company Bylaws. The Company and each Stockholder Designee that is elected or appointed to the Board shall execute the Company’s form of indemnification agreement for its directors and officers and the Company shall maintain directors’ and officers’ indemnity insurance coverage reasonably satisfactory to the Board or compensation committee thereof.

No provision hereof can be waived, except by a writing signed by the party against whom such waiver is to be enforced, and any such waiver shall apply only in the particular instance in which such waiver shall have been given.

(ii) Neither any failure or delay in exercising any right or remedy hereunder or in requiring satisfaction of any condition herein nor any course of dealing shall constitute a waiver of or prevent any party from enforcing any right or remedy or from requiring satisfaction of any condition. No notice to or demand on a party waives or otherwise affects any obligation of that party or impairs any right of the party giving such notice or making such demand, including any right to take any action without notice or demand not otherwise required by this Agreement.

(c) No Assignment or Delegation. No party may assign any right or delegate any obligation hereunder, including by merger, consolidation, operation of law, or otherwise, without the written consent of the other party.

Except as otherwise expressly stated herein, there is no condition precedent to the effectiveness of any provision hereof or thereof.

(e) Severability. A determination by a court or other legal authority that any provision that is not of the essence of this Agreement is legally invalid shall not affect the validity or enforceability of any other provision hereof. The parties shall cooperate in good faith to substitute (or cause such court or other legal authority to substitute) for any provision so held to be invalid a valid provision, as alike in substance to such invalid provision as is lawful.

(f) Third Party Beneficiaries.
