RECITALS

     A. Concurrently with the execution of this Agreement, Parent, Voyager Merger Corp., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”) and the Company have entered into an Agreement and Plan of Reorganization (the “Reorganization Agreement”), which provides for, among other things, the merger (the “Merger”) of Merger Sub with and into the Company.

     B. Pursuant to the Merger, all of the issued and outstanding shares of capital stock of the Company will be converted into the right to receive the consideration set forth in the Reorganization Agreement, all upon the terms and subject to the conditions set forth in the Reorganization Agreement.

     C. As of the date of this Agreement, the Stockholder is the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) of the number of shares of outstanding capital stock of Parent and other securities convertible into, or exercisable or exchangeable for, shares of capital stock of Parent, all as set forth on the signature page of this Agreement.

     D. In consideration of the execution of the Reorganization Agreement by the Company, Stockholder desires to vote the Shares (defined below) so as to facilitate the consummation of the Merger.

     NOW, THEREFORE, the parties hereto hereby agree as follows:

     1. Agreement to Vote Shares. Until the Expiration Date (defined below), at every annual or special meeting of stockholders of Parent called with respect to any of the following, and at every adjournment or postponement thereof, and on every action or approval by written consent of stockholders of Parent with respect to any of the following (each such annual, special, adjourned or postponed meeting and written consent, each, a “Stockholder Vote”), Stockholder shall vote, to the extent not voted by the person(s) appointed under the Proxy (as defined in Section 2), all shares of capital stock of Parent as to which Stockholder holds beneficial ownership at the time of such Stockholder Vote (collectively, the “Shares”) as follows:

          (a) in favor of approval of the issuance of shares of the Common Stock of Parent, par value $0.001 per share, in connection with the Merger; and

          (b) in favor of any adjournment or postponement recommended by Parent with respect to any stockholder meeting in connection with the issuance of shares of Parent Common Stock pursuant to the Reorganization Agreement and the Merger.

     As used herein, the term “Expiration Date” shall mean the earliest to occur of (i) such date as shall be mutually agreed upon in writing by Parent, the Company and Stockholder, (ii) such date and time as the Merger shall become effective in accordance with the terms and provisions of the Reorganization Agreement or (iii) the termination of the Reorganization Agreement in accordance with the terms thereof.

     2. Irrevocable Proxy. Concurrently with the execution of this Agreement, Stockholder agrees to deliver to the Company an irrevocable proxy in the form attached hereto as Exhibit A (the “Proxy”), which shall be irrevocable to the fullest extent permitted by applicable law, covering the total number of Shares as to which Stockholder holds beneficial ownership at the time of the applicable Stockholder Vote.

     3. No Inconsistent Agreement. Stockholder hereby covenants and agrees (i) not to enter into any agreement that would restrict or interfere with the performance of Stockholder’s obligations hereunder and (ii) not to knowingly take any action that would reasonably be expected to make any of Stockholder’s representations or warranties contained herein untrue or incorrect or have the effect of preventing Stockholder from performing his, her or its obligations under this Agreement; provided, however, nothing in this Agreement shall limit the ability of Stockholder to sell, transfer or assign the shares of Parent capital stock held by the Stockholder from time to time, including, without limitation, distributing any such shares to limited partners, if applicable.

     4. Representations, Warranties of Stockholder. As of the date hereof, Stockholder represents and warrants to the Company as follows:

          (i) Stockholder is the beneficial owner of the shares of Parent capital stock set forth on the signature page hereto (the “Currently Owned Shares”), with full power to vote or direct the voting of the Currently Owned Shares for and on behalf of any and all beneficial owners of the Currently Owned Shares.

          (ii) The Currently Owned Shares are free and clear of any rights of first refusal, co-sale rights, security interests, liens, pledges, claims, options, charges or other encumbrances of any kind or nature, in each case that would impair the right of the Stockholder to vote such shares.

          (iii) Stockholder does not beneficially own any shares of capital stock of Parent, or any securities convertible into, or exchangeable or exercisable for, shares of capital stock of Parent, other than the Currently Owned Shares.

          (iv) Stockholder has all necessary power, authority and legal capacity to make, enter into and carry out the terms of this Agreement and the Proxy and no other proceedings or actions on the part of the Stockholder are necessary to authorize the execution, delivery or performance of this Agreement or the Proxy.

     5. Additional Documents. Stockholder hereby covenants and agrees to execute and deliver any additional documents reasonably necessary or desirable to carry out the terms of this Agreement.

     6. Consents and Waivers. Stockholder hereby gives any consents or waivers that are reasonably required for the consummation of the Merger under the terms of any agreement to which Stockholder is a party or pursuant to any rights Stockholder may have.

     7. Termination. The term of this Agreement and the Proxy delivered in connection herewith shall commence on the date hereof and shall terminate and shall have no further force or effect as of the Expiration Date.

     8. No Survival of Representations and Warranties. The representations and warranties of the parties contained herein shall expire, and shall be terminated and extinguished, upon the Expiration Date.

     9. No Limitation. Nothing in this Agreement shall be construed to prohibit Stockholder from taking any action solely in his or her capacity as an officer or member of the Board of Directors of Parent, if applicable.

     10. Miscellaneous.

          (a) Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other persons, entities or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such illegal, void or unenforceable provision of this Agreement with a legal, valid and enforceable provision that will achieve, to the greatest extent possible, the economic, business and other purposes of such illegal, void or unenforceable provision.

          (b) Binding Effect and Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective successors by operation of law, but, except as otherwise specifically provided herein, neither this Agreement nor any of the rights, interests or obligations of Stockholder hereunder may be assigned to any other person without the prior written consent of the Company.

          (c) Amendments and Modification. This Agreement may not be modified, amended, altered or supplemented except upon the execution and delivery of a written agreement executed by each of the parties hereto.

          (d) Waiver. No waiver by any party hereto of any condition or of any breach of any provision of this Agreement shall be effective unless in writing.

          (e) Specific Performance; Injunctive Relief. The parties acknowledge that the Company will be irreparably harmed and that there will be no adequate remedy at law for a violation of any of the covenants or agreements of Stockholder set forth herein. Therefore, it is agreed that, in addition to any other remedies that may be available to the Company upon any such violation, the Company shall have the right to enforce such covenants and agreements by specific performance, injunctive relief or by any other means available to the Company at law or in equity.
