RECITALS

WHEREAS, concurrently with the execution and delivery of this Agreement, (i) the Company, (ii) Parent and (iii) Vineyard Merger Sub Inc., a Delaware corporation and wholly-owned subsidiary of Parent (“Merger Sub”), are entering into an Agreement and Plan of Merger (as may be amended from time to time, the “Merger Agreement”), which provides for the merger of Merger Sub with and into the Company (the “Merger”), with the Company continuing as the surviving corporation in the Merger as a wholly-owned subsidiary of Parent;

WHEREAS, as of the date hereof, each Stockholder is the record and/or “beneficial owner” (within the meaning of Rule 13d-3 under the Exchange Act) of the number of shares of common stock, par value $0.001 per share, of the Company (“Common Stock”) set forth opposite such Stockholder’s name on Exhibit A hereto under the heading “Owned Shares”, being all of the shares of Common Stock owned of record or beneficially by such Stockholder as of the date hereof (the “Owned Shares”); and

WHEREAS, as a condition to the willingness of Parent to enter into the Merger Agreement and as an inducement and in consideration therefor, Parent has required that each Stockholder agrees to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, each Stockholder and Parent hereby agree as follows:

1. Agreement to Vote the Covered Shares; Proxy.

1.1 Agreement to Vote and Support. Beginning on the date hereof until the Termination Date (as defined below), at every meeting of the stockholders of the Company (the “Company Stockholders”), including any postponement or adjournment thereof, or in any other circumstance, however called (including by written consent), each Stockholder agrees to, and if applicable, to cause its controlled Affiliates to, unconditionally and irrevocably affirmatively vote (including via proxy) or execute consents with respect to (or cause to be voted (including via proxy) or consents to be executed with respect to) (and not to withdraw any such vote or consent with respect to) all of the Owned Shares and any additional shares of Common Stock or other voting securities of the Company acquired by such Stockholder or its respective controlled Affiliates after the date hereof and prior to the Termination Date (collectively, and together with the Owned Shares, the “Covered Shares”) as follows: (a) in favor of (i) the adoption of the Merger Agreement and the approval of the Merger, (ii) the adoption of any amended and restated Merger Agreement or amendment to the Merger Agreement that, in any such case, does not (A) decrease

the Merger Consideration, (B) change the form of the Merger Consideration, or (C) extend the End Date (after giving effect to the extensions thereof contemplated by the Merger Agreement) (clauses (A) – (C) collectively, an “Adverse Amendment”), or otherwise result in the Merger Agreement being less favorable to the Company Stockholders than the Merger Agreement in effect as of the date of this Agreement, (iii) the approval of any proposal to adjourn or postpone any Company Stockholder Meeting if the Company or Parent proposes or requests such postponement or adjournment in accordance with Section 4.4(b) of the Merger Agreement, and (iv) the approval of any other proposal considered and voted upon by the Company Stockholders at any Company Stockholder Meeting (or by written consent) necessary or desirable for the consummation of the Merger or the other Transactions, and (b) against (i) any proposal, action or agreement that would reasonably be expected to result in a breach of any covenant, representation or warranty or other obligation or agreement of the Company contained in the Merger Agreement or that would reasonably be expected to result in any condition set forth in the Merger Agreement not being satisfied or not being fulfilled prior to the Termination Date, (ii) any Acquisition Proposal, or any other proposal made in opposition to, in competition with, or inconsistent with, the Merger Agreement, the Merger or the other Transactions, (iii) any reorganization, recapitalization, dissolution, liquidation, winding up or similar extraordinary transaction involving the Company (except as contemplated by the Merger Agreement) and (iv) any other action, agreement or proposal which would reasonably be expected to prevent or materially impede or materially delay the consummation of the Merger or any of the other Transactions (clauses (a) and (b), collectively, the “Supported Matters”). Each Stockholder agrees to, and agrees to cause its applicable controlled Affiliates to, be present, in person or by proxy, at every meeting of the Company Stockholders, including any postponement or adjournment thereof, or in any other circumstance, however called, to vote on the Supported Matters (in the manner described in this Section 1.1) so that all of the Covered Shares will be counted for purposes of determining the presence of a quorum at such meeting, or otherwise cause the Covered Shares to be counted as present thereat for purposes of establishing a quorum. For the avoidance of doubt, other than with respect to the Supported Matters, no Stockholder has any obligation to vote the Covered Shares in any particular manner. In the event that the Company and Parent agree to effectuate the Transactions by means of a tender offer, each Stockholder shall tender (and shall not withdraw), or cause to be tendered (and cause to not withdraw), all of its Covered Shares pursuant to and in accordance with the terms of such tender offer prior to the time required for such Covered Shares to be validly tendered for acceptance in such tender offer.

1.2 Return of Proxy Card or Voting Instructions. Each Stockholder shall execute and deliver (or cause the holders of record of the Covered Shares to execute and deliver), within ten (10) business days of receipt, any proxy card or voting instructions it receives that are sent to Company Stockholders soliciting proxies with respect to the Supported Matters, which shall vote the Covered Shares in the manner described in Section 1.1 of this Agreement. At Parent’s reasonable request, each Stockholder shall provide reasonable evidence of such execution and delivery of such proxy card or voting instructions.

1.3 Proxy. If any Stockholder (i) fails to comply with its obligations under Section 1.2 or (ii) otherwise attempts to vote such Stockholder’s Covered Shares, in person or by proxy, in a manner which is inconsistent with Section 1.1, (each, a “Triggering Event”), such Stockholder will be deemed, upon and as of the time of such Triggering Event, to irrevocably appoint as its proxy and attorney-in-fact the officers of Parent, each of them individually, with full

2

power of substitution and resubstitution, to vote such Stockholder’s Covered Shares (to the extent such Covered Shares are entitled to so vote) in accordance with Section 1.1 at the Company Stockholder Meeting (including any postponement, recess or adjournment thereof) prior to the Termination Date at which any Supported Matters are to be considered; provided, that the proxy contemplated by this Section 1.3 shall not arise and shall have no force or effect prior to the occurrence of a Triggering Event, from and after which the proxy shall be irrevocable prior to the Termination Date, at which time any such proxy shall terminate; provided, further, for the avoidance of doubt, that each Stockholder shall retain at all times the right to vote such Stockholder’s Covered Shares (or to direct how such Covered Shares shall be voted) in such Stockholder’s sole discretion on matters (other than Supported Matters). Parent may terminate this proxy with respect to such Stockholder at any time at its sole election by written notice provided to such Stockholder.

1.4 Directors and Officers. Stockholder signs this Agreement solely in such Stockholder’s capacity as a stockholder of the Company, and not in such Stockholder’s capacity as a director, officer or employee of the Company. Subject, in each case of clauses (x) and (y), to compliance with the obligations set forth in Sections 4.3 and 5.1 of the Merger Agreement that are applicable to the Company’s officers, directors and other Representatives, (x) nothing in this Agreement shall be construed to prohibit Stockholder or any of Stockholder’s representatives who is an officer or member of the Board of Directors from taking any action (or failure to act) in his or her capacity as an officer or member of the Board of Directors or from taking any action with respect to any Acquisition Proposal solely in their capacity as such an officer or director or in the exercise of his or her fiduciary duties in his or her capacity as director or officer of the Company, or prevent or be construed to create any obligation on the part of any director or officer of the Company from taking any action in his or her capacity as such director or officer, and (y) no action taken solely in any such capacity as an officer or director of the Company shall be deemed to constitute a breach of this Agreement.

2. Termination. This Agreement shall terminate automatically and without further action upon the earliest to occur of: (i) the valid termination of the Merger Agreement in accordance with its terms, (ii) the Effective Time, and (iii) the date of adoption of any material modification, waiver or amendment to any provision of the Merger Agreement that constitutes an Adverse Amendment (unless consented to by such Stockholder) (such date, the “Termination Date”); provided that the provisions set forth in Section 7 and Sections 10 through 20 of this Agreement shall survive the termination of this Agreement; and provided further that, subject to the provisions set forth in Sections 7.2, 7.3(b) and 8.5(b) of the Merger Agreement (which are hereby expressly acknowledged and agreed by each Stockholder), the termination of this Agreement shall not prevent any party hereto from seeking any remedies (at law or in equity) against any other party hereto for that party’s Willful Breach of this Agreement that may have occurred at or before such termination. For the purpose hereof, “Willful Breach” means a material breach of this Agreement by a party hereto prior to the Termination Date that is a consequence of an act, or failure to act, undertaken by the breaching party with the knowledge that the taking of such act, or failure to act, would result in such breach.

3. Certain Covenants of Each Stockholder.

3.1 Transfers. Beginning on the date hereof until the Termination Date, each Stockholder hereby covenants and agrees that, (a) except (x) for the Transfer of Covered Shares to its Affiliates (provided that, as a condition precedent to such Transfer, such transferee executes a voting agreement on the same terms as this Agreement), or (y) as expressly contemplated pursuant to this Agreement or the Merger Agreement, such Stockholder shall not, and shall direct its Affiliates and their respective Representatives not to, directly or indirectly (i) tender any Covered Shares into any tender or exchange offer, (ii) Transfer or enter into any Contract, option, agreement, understanding or other arrangement with respect to the Transfer of, any Covered Shares or beneficial ownership, voting power or any other interest thereof or therein (including by operation of law), (iii) enter into any hedge, swap or other transaction or Contract which is designed to (or is reasonably expected to lead to or result in) a transfer of the economic consequences of ownership of any Covered Shares, whether any such transaction is to be settled by delivery of Covered Shares, in cash or otherwise, (iv) grant any proxies or powers of attorney, deposit any Covered Shares into a voting trust or enter into a voting agreement with respect to any Covered Shares or (v) commit or agree to take any of the foregoing actions and (b) such Stockholder shall not, and shall direct its Affiliates and their respective Representatives not to, directly or indirectly take any action that would reasonably be expected to prevent or materially impair or materially delay the consummation of the transactions contemplated by this Agreement. Without limiting the foregoing, each Stockholder agrees that it shall not, and shall cause each of its Affiliates not to, become a member of a “group” (as defined under Section 13(d) of the Exchange Act) with respect to any securities of the Company for the purpose of opposing or competing with or taking any actions inconsistent with the Transactions. Any Transfer in violation of this Section 3.1 shall be void ab initio. For the purpose hereof, “Transfer” means (1) any direct or indirect offer, sale, assignment, encumbrance, pledge, gift, hedge, hypothecation, disposition, loan or other transfer, or entry into any option or other contract, arrangement or understanding with respect to any offer, sale, assignment, encumbrance, pledge, gift, hedge, hypothecation, disposition, loan or other transfer (whether by merger, consolidation, division, conversion, operation of law or otherwise), of any Covered Shares or any interest in any Covered Shares (in each case other than this Agreement), (2) the deposit of such Covered Shares into a voting trust, the entry into a voting agreement or arrangement (other than this Agreement) with respect to such Covered Shares or the grant of any proxy or power of attorney with respect to such Covered Shares or (3) any contract or commitment (whether or not in writing) to take any of the actions referred to in the foregoing clauses (1) or (2) above.

3.2 Documentation and Information. Except as required by applicable Legal Requirements, each Stockholder shall not, and shall direct its Representatives not to, make any public announcement regarding this Agreement, the Merger Agreement or the transactions contemplated hereby or thereby without the prior written consent of Parent, other than to amend the Schedule 13D to disclose this Agreement as contemplated in Section 3.4 herein. Each Stockholder consents to and hereby authorizes Parent and Merger Sub to publish and disclose in all documents and schedules filed with the SEC, and any press release or other disclosure document that Parent or Merger Sub reasonably determines to be necessary in connection with the Merger and any of the other Transactions, such Stockholder’s identity and ownership of the Covered Shares, the existence of this Agreement and the nature of each Stockholder’s commitments and obligations under this Agreement, and each Stockholder acknowledges that Parent and Merger Sub may, in Parent’s sole discretion, file this Agreement or a form hereof with the SEC or any other Governmental Body. Each party hereto agrees to use its reasonable best efforts to promptly (a)

4

give the other party any information it may reasonably require for the preparation of any such disclosure documents, and (b) notify the other party of any required corrections with respect to any written information supplied by it specifically for use in any such disclosure document, if and to the extent that such party shall become aware that any such information shall have become false or misleading in any material respect.

3.3 No Solicitation. Each Stockholder shall not take any action that the Company would then be prohibited from taking under Section 4.3 of the Merger Agreement as if such Section of the Merger Agreement applied, mutatis mutandis, to each Stockholder.

3.4 Merger Proxy Statement; Schedule 13D. Each Stockholder will use its reasonable best efforts to furnish all information concerning such Stockholder and its Affiliates to Parent and the Company that is reasonably necessary for the preparation and filing of the Merger Proxy Statement, and will otherwise reasonably assist and cooperate with Parent and the Company in the preparation, filing and distribution of the Merger Proxy Statement and the resolution of any comments thereto received from the SEC.

13. Applicable Legal Requirements; Jurisdiction; Specific Performance; Remedies.

(a) This Agreement and any matters or disputes relating thereto shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof. In any action or proceeding arising out of or relating to this Agreement or any of the Transactions: (i) each of the parties hereto irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Chancery Court of the State of Delaware and any state appellate court therefrom or, if (but only if) such court lacks subject matter jurisdiction, the United States District Court sitting in New Castle County in the State of Delaware and any appellate court therefrom (collectively, the “Delaware Courts”); and (ii) each of the parties hereto irrevocably consents to service of process by first class certified mail, return receipt requested, postage prepaid, to the address at which such party is to receive notice in accordance with Section 10. Each of the parties hereto irrevocably and unconditionally (1) agrees not to commence any such action or proceeding except in the Delaware Courts, (2) agrees that any claim in respect of any such action or proceeding may be heard and determined in the Delaware Courts, (3) waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the jurisdiction or laying of venue of any such action or proceeding in the Delaware Courts and (4) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in the Delaware Courts.

sentence, the parties hereto acknowledge and agree that (i) the parties hereto shall be entitled to an injunction or injunctions, specific performance, or other equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in the courts described in Section 13(a) without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement, and (ii) the right of specific performance is an integral part of the Transactions and the transactions contemplated by this Agreement. Each of the parties hereto agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that the other parties have an adequate remedy at law or that an award of specific performance is not an appropriate remedy for any reason at law or equity. The parties hereto acknowledge and agree that any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 13(b) shall not be required to provide any bond or other security in connection with any such order or injunction.

(c) EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING BETWEEN THE PARTIES (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE), INCLUDING ANY COUNTERCLAIM, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF ANY PARTY HERETO IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT THEREOF. EACH PARTY HERETO (I) MAKES THIS WAIVER VOLUNTARILY AND (II) ACKNOWLEDGES THAT SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS CONTAINED IN THIS SECTION 13(c).

14. Assignability. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the parties hereto and their respective successors and permitted assigns; provided, however, that neither this Agreement nor any of the rights hereunder may be assigned by a party hereto without the prior written consent of the other parties, and any attempted assignment of this Agreement or any of such rights without such consent shall be void and of no effect, except that Parent may assign all or any of its rights and obligations under this Agreement to any controlled Affiliate of Parent.

15. No Third Party Beneficiaries. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person (other than the parties hereto) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

by this Agreement or in respect of any oral representations made or alleged to be made in connection herewith. In no event shall any party hereto, and each party hereto agrees to use its reasonable best efforts to cause its Non-Recourse Parties not to, seek to enforce this Agreement against, make any claims for breach of this Agreement against, or seek to recover monetary damages from, any Non-Recourse Party not a party to this Agreement.

17. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Body to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

18. Amendment. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

19. Waiver. No failure on the part of any party hereto to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any party in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. Any such extension or waiver shall be valid only if is expressly set forth in a written instrument duly executed and delivered on behalf of the parties hereto to be bound thereby, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

20. No Agreement until Executed. Irrespective of negotiations among the parties or the exchanging of drafts of this Agreement, this Agreement shall not (and, for clarity, no negotiations or unwritten agreements relating to the substance thereof shall) constitute or be deemed to evidence a contract, agreement, arrangement or understanding between the parties unless and until (a) the Board of Directors has approved, for purposes of any applicable anti-takeover Legal Requirements, and any applicable provision of the bylaws or certificate of incorporation of the Company (in each case, as amended, restated, modified or supplemented as of the date hereof), this Agreement and the transactions contemplated by the Merger Agreement and this Agreement, (b) the Merger Agreement is executed and delivered by all parties thereto, and (c) this Agreement is executed and delivered by all parties hereto.
