Any acquisition of Shares (defined below) shall occur pursuant to the Stock Transfer Agreements to be identified on Exhibit A hereto (each a “Stock Transfer Agreement” and, together, the “Stock Transfer Agreements”) which agreements shall be in form and substance satisfactory to the Company and subject to the execution thereof by                     , Stockholder and the Company.

D. In exchange for the mutual promises herein and for other good and valuable consideration, the sufficiency of which is hereby acknowledged and agreed, the parties hereto wish to enter into this Agreement.

AGREEMENT

The parties hereto agree as follows:

1. No Conflict with Investor Voting Agreement. In the event of a conflict between the terms and provisions of this Agreement and the terms and provisions of the Investor Voting Agreement, the terms and provisions of the Investor Voting Agreement will prevail, and Proxyholder or Stockholder, as the case may be, shall be obligated to vote the Shares in accordance with the Investor Voting Agreement.

2. Voting Arrangements. Stockholder hereby agrees that Proxyholder shall have the right to vote all the Shares, in his sole discretion, on all matters submitted to a vote of stockholders of the Company at a meeting of stockholders or through the solicitation of a written consent of stockholders (whether of any individual class of stock or of multiple classes of stock voting together) except for:

2.1 any issuance, or series of related issuances, of capital stock in a capital raising transaction by the Company that is submitted for stockholder approval in which the number of shares of capital stock so issued will exceed 20% of the total number of shares of capital stock of the Company outstanding immediately prior to such issuance; and

2.2 any matter, the outcome of the vote on which would disproportionately, materially and adversely affect Stockholder, as compared to other holders of the same class(es) of capital stock of Company, provided that, subject to Section 2.1, increases in the authorized number of shares of preferred stock generally, or the authorized number of any class of preferred stock of the Company or the issuance of securities of the Company senior to such class of preferred stock will not be viewed as having such an adverse effect.

With respect to the excepted matters described in Sections 2.1 and 2.2 above, Stockholder shall have the right to (i) instruct Proxyholder in writing as to the manner in which the Shares shall be voted or (ii) vote the Shares in person or by action by written consent, as applicable, in which case Stockholder shall notify Proxyholder in writing that Stockholder intends to so vote. In addition, Proxyholder shall not have any right to waive notice by the Company to Stockholder. Such instruction or notice shall be provided to Proxyholder at least five (5) days prior to the date of any meeting of stockholders at which such matter is to be voted upon or as promptly as reasonably practicable upon Stockholder becoming aware that such matter is to be acted upon by written consent. In the event that Stockholder does not so instruct Proxyholder or notify Proxyholder of its intention to so vote or act by written consent, Proxyholder shall abstain from voting the Shares in respect of such matters.

3. Illustrative Examples. Matters on which Proxyholder shall be entitled to vote, pursuant to Section 2 include, but are not limited to, the following, which are presented here solely by way of example:

3.1 election, replacement or removal of directors of the Company (each, a “Director”);

2

3.2 sale or other disposition of all or substantially all of the Company’s assets, provided, that any distribution to Company stockholders of the proceeds of such sale or disposition are made in accordance with the Company’s certificate of incorporation, as then in effect;

3.3 mergers of, or acquisitions by, the Company or its subsidiaries that are submitted for stockholder approval; and

3.4 adoption by the Company of a rights plan or similar takeover defensive arrangements, or amendments thereof, which plan provides that a triggering event will occur only upon the acquisition by a stockholder of 15% or more of the Company’s shares of voting capital stock.

4. Stockholder to Abstain from Voting. Stockholder agrees that, unless Proxyholder provides explicit written instruction to vote the 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 the Shares (in person, by proxy or by action by written consent, as applicable) on all matters other than with respect to the matters set forth in Sections 2.1 and 2.2 above.

5. Irrevocable Proxy and Power of Attorney. To secure Stockholder’s obligations to vote the Shares in accordance with this Agreement and to comply with the other terms hereof, Stockholder hereby appoints Proxyholder, or Proxyholder’s named designee(s), as 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 the Shares solely in accordance with the provisions set forth in this Agreement, and to execute all appropriate instruments solely in a manner consistent with the terms of this Agreement on behalf of Stockholder. The proxy and power granted by Stockholder pursuant to this Section 5 are coupled with an interest and are given to Proxyholder to secure the performance of Stockholder’s duties under this Agreement. The aforesaid proxy and power will (a) be irrevocable for the term hereof, and (b) survive the merger, consolidation, conversion or reorganization of Stockholder or any other entity holding the Shares.

6. Additional Representations, Covenants and Agreements.

6.1 Transfers by Stockholder.

(a) To the extent Stockholder has acquired shares that are subject to the ROFR Agreement, Stockholder hereby acknowledges that Proxyholder is an intended third-party beneficiary of the ROFR Agreement and the Stock Transfer Agreements.

(b) Pursuant to the Stock Transfer Agreements and, to the extent applicable, Section 6 of the ROFR Agreement, Stockholder may not transfer, assign, pledge or otherwise dispose of or encumber the Shares (collectively, a “Transfer”) without the prior written consent of the Company, unless otherwise permitted by the Stock Transfer Agreements and, if applicable, the ROFR Agreement.

3

(c) If Stockholder’s Transfer of Shares is permitted under the terms of the Stock Transfer Agreements and, if applicable, the ROFR Agreement, or is otherwise consented to by the Company pursuant to the Stock Transfer Agreements and, if applicable, the ROFR Agreement, such Transfer shall not take effect until the pledgee, transferee or donee of such Shares (the “Transferee”) executes and delivers to Proxyholder and the Company an agreement substantially in the form of this Agreement (the “Transferee Voting Agreement”), it being understood and agreed that the Company shall be entitled to issue stop transfer instructions in respect of such Shares to preclude any transfer of Shares in contravention of the foregoing. Notwithstanding the foregoing, six (6) months following the completion of the initial firm commitment underwritten public offering by the Company (the “Initial Public Offering”) under the Securities Act of 1933, as amended (the “Securities Act”), the Transferee shall not be required to enter into a Transferee Voting Agreement (and the Shares shall no longer be subject to the restrictions of this Agreement) if at the time of such Transfer the Stockholder is transferring (x) Class B Common Stock that, upon completion of such Transfer, shall automatically become Class A Common Stock, or (y) Class A Common Stock.

For clarification purposes, Shares Transferred six (6) months following the Initial Public Offering and in accordance with Section 6.1(c) above shall no longer be subject to this Agreement and the Transferee shall not be treated as a “Stockholder” for purposes of this Agreement. Except as set forth in the prior sentence, upon satisfaction of the provisions of this Section 6.1, such Transferee shall be treated as a “Stockholder” for purposes of this Agreement.

6.2 Legends. The Company shall cause each certificate representing the Shares to bear the following legend, in addition to any legends that may be required by state or federal securities laws or the terms of the Company’s Bylaws or any voting or other agreements that apply to Stockholder:

THE SHARES EVIDENCED HEREBY ARE SUBJECT TO A HOLDER VOTING AGREEMENT BY AND AMONG THE COMPANY AND CERTAIN STOCKHOLDERS OF THE COMPANY (COPIES OF WHICH MAY BE OBTAINED FROM THE COMPANY) WHICH INCLUDES PROVISIONS POTENTIALLY RESTRICTING THE STOCKHOLDER’S RIGHT TO VOTE OR TRANSFER AN INTEREST IN THE SHARES EVIDENCED HEREBY, AND BY ACCEPTING ANY INTEREST IN SUCH SHARES THE PERSON ACCEPTING SUCH INTEREST SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF SAID HOLDER VOTING AGREEMENT.

6.3 Stock Splits, Dividends, Etc. In the event of any issuance of shares of the Company’s voting securities hereafter to Stockholder as a result of Stockholder’s ownership of Shares (including, without limitation, in connection with any stock split, stock dividend, recapitalization, reorganization, or the like), such shares shall automatically become subject to this Agreement and shall be endorsed with the legend set forth in Section 6.2.

6.4 Specific Enforcement. It is agreed and understood that monetary damages would not adequately compensate an injured party for the breach of this Agreement by

4

any party, that this Agreement shall be specifically enforceable, and that any breach or threatened breach of this Agreement shall be the proper subject of a temporary or permanent injunction or restraining order. Further, each party hereto waives any claim or defense that there is an adequate remedy at law for such breach or threatened breach.

6.5 Securities Laws, Rules and Regulations. Stockholder, the Company and Proxyholder agree and understand that Stockholder, the Company and/or Proxyholder may become subject to the registration and/or reporting requirements, rules and regulations of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Securities Act and/or any state and federal securities laws (collectively with the Exchange Act and the Securities Act, the “Securities Laws”). Stockholder, the Company and Proxyholder agree to use their respective commercially reasonable efforts to comply with the Securities Laws and to reasonably assist each other in complying with the Securities Laws in a timely and prompt manner. Such compliance may include, for example and without limiting the foregoing, the filing and updating and maintaining of Form 13G and/or Form 13D under the Exchange Act.

6.6 Other Arrangements. During the term of this Agreement, Stockholder will not, without Proxyholder’s prior written consent, voluntarily convert any Shares of the Company’s Class B Common Stock into Shares of the Company’s Class A Common Stock; provided, however, that a conversion of Shares resulting from or in connection with a Transfer (as such term is defined in the Company’s Eleventh Amended and Restated Certificate of Incorporation, as amended from time to time) shall not constitute a “voluntary” conversion for the purposes of this Agreement and any such transfer is not restricted by this Section 6.6.

6.7 Proxyholder’s Liability. In voting the Shares in accordance with Section 2 hereof, Proxyholder shall not be liable for any error of judgment nor for any act done or omitted, nor for any mistake of fact or law nor for anything which Proxyholder may do or refrain from doing in good faith, nor shall Proxyholder have any accountability hereunder, except for Proxyholder’s own bad faith, gross negligence or willful misconduct. Furthermore, upon any judicial or other inquiry or investigation of or concerning Proxyholder’s acts pursuant to Proxyholder’s rights and powers as Proxyholder, such acts shall be deemed reasonable and in the best interests of Stockholder unless proved to the contrary by clear and convincing evidence.

7. Termination.

7.1 Termination Events. This Agreement shall automatically terminate:

(a) upon the liquidation, dissolution or winding up of the business operations of the Company;

(b) upon the execution by the Company of a general assignment for the benefit of creditors or the appointment of a receiver or trustee to take possession of the property and assets of the Company;

(c) in the sole discretion of Proxyholder, upon the express written consent of Proxyholder (which Proxyholder shall be under no obligation to provide); or

5

(d) upon the death or permanent and substantial incapacity of Proxyholder, as determined in good faith by the Company’s board of directors, unless Proxyholder is actively contesting such determination of incapacity.

7.2 Conversion of Shares upon Termination of Agreement. In the event that this Agreement is terminated pursuant to Section 7.1(d) (a “Conversion Event”), Stockholder hereby agrees that this Agreement shall constitute notice to the Company that contingent upon and effective as of such Conversion Event, all Shares held at the time of such Conversion Event by Stockholder shall automatically (without any further action on the part of Stockholder and/or any of Stockholder’s respective affiliates) convert into shares of the Company’s Class A Common Stock pursuant to Article IV(D), Section 5(a) the Company’s Eleventh Amended and Restated Certificate of Incorporation, as amended from time to time (the “Optional Conversion Provision”). In addition, upon such Conversion Event, Stockholder shall promptly deliver to the Company the stock certificates representing all Shares to be converted pursuant to the Optional Conversion Provision in accordance with this section.

7.3 Legends Following Termination of Agreement. At any time after termination of either of the Investor Voting Agreement or this Agreement, any holder of a stock certificate may surrender such certificate to the Company for appropriate modifications to the legend, and the Company shall, as promptly as reasonably practicable, reissue a new certificate with any legends that may be required by the Securities Laws or the terms of any voting or other agreements that remain applicable.
