RECITALS

The Stockholder holds shares of Common Stock of the Company. This Agreement, among other things, requires the Stockholder to vote all such shares of Common Stock and all shares of capital stock of the Company which such Stockholder currently owns or hereafter acquires or as to which he otherwise exercises voting or dispositive authority (together all such shares referred to in this sentence and any securities of the Company issued with respect to, upon conversion of, or in exchange or substitution of such shares, and any other voting securities of the Company subsequently acquired by the Stockholder, the “Shares”) in the manner set forth herein. This agreement is being entered into in exchange for a payment of $100 in cash from the Proxyholder to Stockholder and for other good and valuable consideration, the sufficiency of which is hereby acknowledged and agreed.

AGREEMENT

The parties agree as follows:

1. Voting for the Election of Directors. At each annual meeting of the stockholders of the Company, or at any meeting of the stockholders of the Company at which members of the Board of Directors of the Company are to be elected, or whenever members of the Board of Directors are to be elected by written consent, the Stockholder agrees to vote (in person, by proxy or by action by written consent, as applicable) with respect to all Shares so as to elect the members of the Board of Directors designated in writing by the Proxyholder. At any meeting of the stockholders of the Company at which members of the Board of Directors of the Company are to be removed, or whenever members of the Board of Directors are to be removed by written consent, the Stockholder agrees to vote or act with respect to his Shares so as to remove any director designated in writing by Proxyholder. Notwithstanding the foregoing or anything to the contrary contained herein, to the extent that Stockholder and Proxyholder are both parties (or become parties) to the Voting Agreement between the Company, certain stockholders and investors of the Company, dated as of April 29, 2005, as amended from time to time (the “Investor Voting Agreement”), Stockholder agrees to continue to be bound by the Investor Voting Agreement and, to the extent that any provisions of this Agreement conflict with the provisions of the Investor Voting Agreement regarding the election or removal of directors (the “Director Provisions”), the Director Provisions (including without limitation any proxies given with respect thereto) shall govern the election and removal of directors under this Agreement. Proxyholder agrees to continue to be bound by the Investor Voting Agreement and shall vote (to the extent Proxyholder holds a proxy) and otherwise act with respect to any Shares as and if required under the Investor Voting Agreement.

2. Voting Agreement On All Matters. Stockholder hereby agrees with respect to all Shares:

(a) In the event that the Proxyholder instructs (or otherwise requests) that Stockholder vote in favor of any Acquisition (an “Approved Sale”), any Certificate Amendment and/or any Other Matter, then the Stockholder shall (i) after receiving proper notice of any meeting of stockholders of the Company to vote on the approval of an Approved Sale, a Certificate Amendment and/or Other Matter (or, if no notice is required or such notice is properly waived, after notice from the Proxyholder is given), be present, in person or by proxy, as a holder of Shares at all such meetings and be counted for the purposes of determining the presence of a quorum at such meetings and (ii) vote (in person, by proxy or by action by written consent, as applicable) all Shares as to which the Stockholder has beneficial ownership or as to which he otherwise exercises voting or dispositive authority (A) in favor of such Approved Sale or Certificate Amendment, (B) in the case of an Approved Sale, in opposition of any and all other Acquisitions for which a vote is taken while an Approved Sale is still pending that would reasonably be expected to delay or impair the ability of the Company to consummate such Approved Sale, and (C) in the case of an Other Matter, in the manner directed by the Proxyholder. Notwithstanding the foregoing, in the case of an Approved Sale, the Stockholder shall not be required to assume personal liability greater than the liability assumed by the Proxyholder that continues after the transaction closing for breach of representations, warranties or other obligations except (x) to the extent of the consideration received in the transaction or (y) for liability attributable to fraud or willful misconduct on the part of the Stockholder. The Stockholder shall refrain from exercising any dissenters’ rights, appraisal rights or similar rights under applicable law at any time in connection with such Approved Sale. If the Approved Sale is structured as a sale of the stock of the Company, then the Stockholder hereby agrees to sell and shall sell all of his Shares on the terms and conditions approved by the Proxyholder. Subject to applicable laws, the Stockholder shall take all necessary and desirable actions approved by the Proxyholder in connection with the consummation of the Approved Sale, including the execution of such agreements and such instruments and other actions reasonably necessary to (i) provide the representations, warranties, indemnities, covenants, conditions, escrow agreements and other provisions and agreements relating to such Approved Sale, and (ii) effectuate the allocation and distribution of the aggregate consideration upon consummation of the Approved Sale.

(b) In the event that the Proxyholder instructs (or otherwise requests) that Stockholder vote against any Acquisition (a “Rejected Sale”), any Certificate Amendment and/or any Other Matter, then the Stockholder shall (i) after receiving proper notice of any meeting of stockholders of the Company to vote on the Rejected Sale, such Certificate Amendment and/or Other Matter (or, if no notice is required or such notice is properly waived, after notice from the Proxyholder is given), be present, in person or by proxy, as a holder of Shares at all such meetings and be counted for the purposes of determining the presence of a quorum at such meetings and (ii) vote (in person, by proxy or by action by written consent, as applicable) all Shares as to which the Stockholder has beneficial ownership or as to which he otherwise exercises voting or dispositive authority (A) against such Rejected Sale or Certificate Amendment, and (B) in the case of an Other Matter, in the manner directed by the Proxyholder. If the Rejected Sale is structured as a sale of the stock of the Company, then the Stockholder shall not sell any of his Shares unless permitted to sell in writing by the Proxyholder.

(c) Stockholder agrees that, unless Proxyholder provides explicit written instruction to vote Stockholder’s Shares under this Agreement or Proxyholder provides explicit written notice that Stockholder shall be permitted by Proxyholder to vote in a manner other than as Proxyholder instructs, Stockholder shall abstain from voting any of his Shares (in person, by proxy or by action by written consent, as applicable) on all matters.

(d) In the event of any Transfer by the Stockholder, (i) the Stockholder shall inform the Company and the Proxyholder of such Transfer and (ii) the pledgee, transferee or donee shall furnish the Proxyholder and the Company with a written agreement to be bound by the provisions of this Agreement. Such Transfer shall not be valid unless and until the Company and the Proxyholder receive such written agreement. In the event of any Transfer by the Stockholder, the Stockholder shall inform the Company and the Proxyholder of such Transfer no less than 5 business days prior to such Transfer. Such pledgee, transferee or donee shall be treated as a “Stockholder” for purposes of this Agreement. For avoidance of doubt, the Company shall not permit the transfer of any of the Shares on its books or issue new certificates representing any such Shares unless and until the person(s) to whom such Shares are to be transferred shall have executed the written agreement referred to in this Section 2 and any additional agreement required under any other applicable agreements between the parties hereto.

For purposes of this Section 2:

“Acquisition” shall mean any (i) event that results in a liquidation, dissolution or winding up, or is deemed to be a liquidation, dissolution or winding up of the Company under the Company’s Certificate of Incorporation, as the same may be amended from time to time (the “Certificate”) or any (ii) reorganization, consolidation, merger, stock sale, or asset sale of the Company.

“Certificate Amendment” shall mean any amendment of the Certificate.

“Other Matter” shall mean any matter, action, ratification or other event other than an Acquisition or Certificate Amendment for which approval of the holders of the Company’s stock is sought (either by vote or written consent) or upon which such holders are otherwise entitled to vote or consent.

“Transfer” shall mean and include any sale, assignment, encumbrance, hypothecation, pledge, conveyance in trust, gift, transfer by bequest, devise or descent, or other transfer or disposition of any kind, including, but not limited to, transfers to receivers, levying creditors, trustees or receivers in bankruptcy proceedings or general assignees for the benefit of creditors, whether voluntary or by operation of law, directly or indirectly, of any of the Shares.

3. Irrevocable Proxy and Power of Attorney. To secure the Stockholder’s obligations to vote the Shares in accordance with this Agreement and to comply with the other terms hereof, the Stockholder hereby appoints the Proxyholder, or his designees, as such Stockholder’s true and lawful proxy and attorney, with the power to act alone and with full power of substitution, to vote or act by written consent with respect to all of such Stockholder’s Shares in accordance with the provisions set forth in this Agreement, and to execute all appropriate instruments consistent with this Agreement on behalf of such Stockholder. The proxy and power granted by the Stockholder pursuant to this Section are coupled with an interest and are given to secure the performance of such party’s duties under this Agreement. Each such

3

proxy and power will be irrevocable for the term hereof. The proxy and power, so long as any party hereto is an individual, will survive the death, incompetency and disability of such party or any other individual holder of the Shares and, so long as any party hereto is an entity, will survive the merger, consolidation, conversion or reorganization of such party or any other entity holding any Shares.
