WHEREAS, concurrently herewith, Parent, Merger Sub and the Company are entering into an Agreement and Plan of Merger (as such agreement may hereafter be amended from time to time, the “Merger Agreement”), pursuant to which Merger Sub will be merged with and into the Company (the “Merger”).

WHEREAS, as a condition and material inducement to entering into the Merger Agreement, Parent and Merger Sub have required that Stockholder agree, and Stockholder has agreed, to enter into this Agreement.

AGREEMENT

NOW THEREFORE, in consideration of the foregoing, the parties to this Agreement, intending to be legally bound hereby, agree as follows:

Section 1. Definitions. For purposes of this Agreement:

(a) “Beneficially Own” or “Beneficial Ownership” with respect to any securities shall mean having “beneficial ownership” of such securities (as determined pursuant to Rule 13d-3 under the Exchange Act), including pursuant to any agreement, arrangement or understanding, whether or not in writing. Without duplicative counting of the same securities by the same holder, securities Beneficially Owned by a Person shall include securities Beneficially Owned by all other Persons with whom such Person would constitute a “group” within the meaning of Section 13(d)(3) of the Exchange Act and Rule 13d-5(b)(1) under the Exchange Act.

(b) Capitalized terms used and not defined herein and defined in the Merger Agreement have the respective meanings ascribed to such terms in the Merger Agreement notwithstanding any termination of the Merger Agreement.

Section 2. Tender of Shares.

(a) Stockholder shall validly tender or cause to be tendered to Merger Sub pursuant to and in accordance with the terms of the Offer, not later than the tenth Business Day after commencement of the Offer pursuant to Section 1 of the Merger Agreement and Rule 14d-2 under the Exchange Act, the number of outstanding shares of Company Common Stock and Company Preferred Stock Beneficially Owned by it, all of which, for the avoidance of doubt as of the date hereof, are listed on the signature page hereto (the “Existing Shares”), and not to withdraw the Existing Shares, or cause the Existing Shares to be withdrawn, from the Offer at any time (except following the termination or expiration of the Offer without Merger Sub purchasing all shares of Company Common Stock and Company Preferred Stock tendered pursuant to the Offer in accordance with its terms). If Stockholder acquires Beneficial Ownership of any outstanding shares of Company Common Stock or Company Preferred Stock after the date hereof, whether upon the exercise of options, warrants or rights, the conversion or exchange of convertible or exchangeable securities, or by means of purchase, dividend, distribution or otherwise (together with the Existing Shares, the “Shares”; provided, that, solely for purposes of this Section 2(a), the term “Shares” shall not include any shares of Company Common Stock or Company Preferred Stock that are subject of a restricted stock award if such shares are unvested or are subject to repurchase option, risk of forfeiture or other condition on title or ownership under any applicable restricted stock purchase agreement or other Contract with the Company), Stockholder shall validly tender such Shares or cause such Shares to be tendered to Merger Sub pursuant to and in accordance with the Offer, not later than the tenth Business Day after commencement of the Offer pursuant to Section 1 of the Merger Agreement and Rule 14d-2 of the Exchange Act or, if acquired later than such time, on or before the second (2^nd) Business Day after such acquisition, but in any event prior to the Initial Expiration Time, and not withdraw such Shares, or cause such Shares to be withdrawn, from the Offer at any time (except following the termination or expiration of the Offer without Merger Sub purchasing all shares of Company Common Stock and Company Preferred Stock tendered pursuant to the Offer in accordance with its terms). Notwithstanding the foregoing, Stockholder may decline to tender, or may withdraw, any and all of the Stockholder’s Shares if, without the consent of Stockholder, Merger Sub amends the Offer to (i) reduce the Offer Price, other than as specifically permitted by Section 1.01(c) of the Merger Agreement, (ii) reduce the number of shares of Company Common Stock or Company Preferred Stock subject to the Offer, (iii) change the form of consideration payable in the Offer or (iv) amend or modify any term or condition of the Offer or the Merger Agreement in a manner adverse to Stockholder (other than to waive any condition other than the Minimum Condition). Stockholder shall give Merger Sub at least two Business Days’ prior notice of any withdrawal of its Shares permitted under this clause (a) (or such shorter time as may be necessary in order to permit Stockholder to validly exercise its withdrawal rights hereunder).

(b) Stockholder hereby acknowledges and agrees that the obligation of Merger Sub to accept for payment and pay for any Shares in the Offer, including the Shares Beneficially Owned by Stockholder, shall be subject to the terms and conditions of the Merger Agreement and the Offer.

(c) Stockholder hereby agrees to permit Parent and Merger Sub to publish and disclose in the Offer Documents, in any Statement on Schedule 13D or 13G, in any other documents filed with the SEC or any other Governmental Entity, to the extent that Parent

2

reasonably determines such document is required to be disclosed by applicable Laws, and, if the approval of the Company’s stockholders is required under applicable Laws, in the Company Proxy Statement (including all documents and schedules filed with the SEC) and, in each case, in any amendments thereto, its identity and ownership of Company Common Stock and Company Preferred Stock and the nature of its obligations, commitments, arrangements and understandings under this Agreement, the Subsidiary Transfer Agreement and the other agreements and instruments contemplated thereby. Parent, Merger Sub and the Company each hereby agrees to permit Stockholder to publish and disclose its identity, the nature of its obligations, commitments, arrangements and understandings under this Agreement and any other information, in each case that Stockholder reasonably determines is required to be disclosed by applicable Laws (including in any Statement on Schedule 13D or 13G or amendments thereto). Stockholder shall not issue any press release or make any other public statement with respect to Parent, Merger Sub, the Company or this Agreement, the Merger Agreement or the Subsidiary Transfer Agreement, or the transactions contemplated hereby or thereby, except (i) as expressly permitted under the Subsidiary Transfer Agreement or (ii) as may otherwise be required by 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.

Section 3. Provisions Concerning Company Common Stock.

(a) Except as otherwise agreed to in writing by Parent in advance, during the term of this Agreement, the Stockholder irrevocably agrees to vote (or cause to be voted) the Shares, whether issued, heretofore owned or hereafter acquired, at any meeting of the holders of Company Common Stock (the “Common Stockholders”) or of the holders of the Company Preferred Stock (the “Preferred Stockholders”), however called, or in connection with any written consent of the Common Stockholders or the Preferred Stockholders: (i) in favor of the adoption of the Merger Agreement and the approval of the terms thereof, the approval of the Merger and each of the other actions contemplated by the Merger Agreement and this Agreement and any actions required in furtherance thereof and hereof; and (ii) against the following actions, agreements or transactions (other than the Merger, the transactions contemplated by the Merger Agreement, the Subsidiary Transfer Agreement and the Subsidiary Transfer ): (A) any extraordinary corporate transaction, such as a merger, consolidation or other business combination involving the Company or any of its Subsidiaries (including any Takeover Proposal), (B) a sale, lease or transfer of a material amount of assets of the Company or any of its Subsidiaries, or a reorganization, recapitalization, dissolution or liquidation of the Company or any of its Subsidiaries, (C) (1) any change in a majority of the persons who constitute the Company Board, (2) any change in the present capitalization of the Company or any amendment of the Charter Documents of the Company, (3) any other material change in the Company’s corporate structure or business, or (4) any other action requiring the approval of the Common Stockholders or the Preferred Stockholders which, in the case of each of the matters referred to in clauses (C) (1), (2) or (3), is intended or could reasonably be expected to impede, interfere with, delay, postpone, discourage, frustrate the purpose of or adversely affect the Merger or the other transactions contemplated by this Agreement and the Merger Agreement. Stockholder shall not enter into any Contract with any Person, the effect of which would reasonably be expected to be inconsistent with or violative of the provisions and agreements contained in this Agreement.

(b) Stockholder hereby irrevocably appoints Parent and each of its executive officers, in their capacities as officers of Parent, and any of them (the “Grantees”), as Stockholder’s proxy and attorney-in-fact (with full power of substitution and re-substitution), for and in the name, place and stead of Stockholder, to vote the Shares or grant a consent or approval or dissent or disapproval in respect of such Shares in accordance with the express provisions of Section 3(a) hereof and in the discretion of the Grantees on any adjournment proposal as shall properly be presented at any meeting of stockholders of the Company at which any of the matters expressly described in Section 3(a) hereof is to be considered and at any adjournment or postponement thereof. Stockholder represents that any proxies granting the authority to vote heretofore given in respect of the Shares that may still be in effect are not irrevocable, and such proxies are hereby revoked. Stockholder hereby affirms that the irrevocable proxy set forth in this Section 3(b) is given in connection with the execution of the Merger Agreement, that such irrevocable proxy is given to secure the performance of the duties of Stockholder under this Agreement and that such irrevocable proxy is coupled with an interest and may under no circumstances be revoked prior to termination of this Agreement in accordance with Section 8. 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 of the DGCL. Notwithstanding this Section 3(b), the proxy granted by Stockholder shall be revoked upon termination of this Agreement in accordance with its terms. The Grantees may not exercise this irrevocable proxy on any other matter except as expressly provided above. Stockholder shall retain at all times the right to vote the Shares in Stockholder’s sole discretion and without any other limitation on all matters other than those expressly set forth in Section 3(a) that are at any time or from time to time presented for consideration to the Company’s stockholders generally. Parent may terminate this proxy with respect to Stockholder at any time at its sole election by written notice provided to Stockholder. If Stockholder is not the record owner of all the Shares, the Stockholder shall so indicate on the signature page hereto (naming such record owner) and shall cause the record owner thereof to agree to the provisions of Section 2 and 3(a) of this Agreement with respect to such Shares, and to execute and grant an irrevocable proxy conforming to the above provisions of this Section 3(b).

(c) For the avoidance of doubt, to the extent that an Affiliate of Stockholder serves on the Company Board or as an officer of the Company, nothing contained in this Agreement shall in any way restrict or limit such Affiliate of Stockholder serving on the Company Board or as an officer of the Company from taking (or omitting to take) any action in his or her capacity as a director or officer of the Company or otherwise fulfilling his or her fiduciary obligations as a director or officer of the Company.

(n) Enforcement. Stockholder acknowledges and agrees that Parent and Merger Sub may be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms and that any breach of this Agreement by Stockholder may not be adequately compensated by monetary damages alone.

Upon such determination that any term or other provision is invalid, illegal or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the greatest extent possible.
