The voting of Stock in accordance with this Agreement may be effected in person, by proxy, by written consent or in any other manner permitted by the Charter, the Delaware General Corporation Law and any other applicable law.

Section 1.02 Notice of Transfers; Other Covenants. Each Stockholder hereby covenants and agrees (a) to promptly notify the other Stockholders (and/or, to the extent that they then hold any Stock, their respective Permitted Transferees) in writing (email being sufficient) of any Transfer (as defined in the Investor Rights Agreement) of the Stock held or beneficially owned by such Stockholder that would cause the Stockholders and their respective Permitted Transferees, taken together, to hold or own less than 50% of the issued and outstanding voting securities of PubCo, (b) that any Transfer of the Stock held or beneficially owned by such Stockholder to a Permitted Transferee (as defined in the Investor Rights Agreement) shall be conditioned upon such Permitted Transferee's agreement to become a party to this Agreement by execution and delivery of a joinder to this Agreement in form and substance reasonably satisfactory to the other Stockholders, and (c) that such Stockholder will not deposit such Stockholder's Stock into a voting trust or enter into a voting agreement or arrangement with respect to such Stockholder's Stock.

Section 1.03 Representations and Warranties. Each Stockholder hereby represents and warrants, severally as to such Stockholder, and not jointly, to the other Stockholders as follows:

(a)Ownership of Shares. As of the date hereof, the Stockholder is the record and beneficial owner of the number of shares of Class V Common Stock and Class A Common Stock of PubCo set forth on such Stockholder's signature page attached hereto (the "Existing Stock"). On the date hereof, the Existing Stock constitutes all of the Stock owned of record or beneficially owned by such Stockholder (including the Earnout Shares) (as defined in the Transaction Agreement). Such Stockholder has sole voting power and sole power to issue instructions with respect to the matters set forth herein, sole power of disposition, and sole power to agree to all of the matters set forth in this Agreement, in each case with respect to all of the Stockholder's Existing Stock with no limitations, qualifications or restrictions on such rights, subject to applicable securities laws and the terms of this Agreement.

(b)Organization; Power; Binding Agreement. If the Stockholder is an entity, the Stockholder is a legal entity, duly organized, validly existing and in good standing under the laws of its jurisdiction of organization and has full organizational power and authority to enter into and perform all of its obligations under this Agreement. If the Stockholder is an individual, such Stockholder has the legal capacity to enter into and perform all of his or her obligations under this Agreement. The execution, delivery and performance of this Agreement by the Stockholder has been duly and validly authorized by all necessary action on the part of the Stockholder and no other proceedings on the part of the Stockholder are necessary to authorize this Agreement or to consummate the transactions contemplated hereby and will not violate any other agreement to which the Stockholder is a party including, without limitation, any voting agreement, proxy agreement, pledge agreement, shareholders agreement or voting trust or, if the Stockholder is an entity, the Stockholder's organizational documents. This Agreement has been duly and validly executed and delivered by such Stockholder and, assuming the due authorization, execution and delivery by the other Stockholders party hereto, constitutes a valid and binding agreement of such Stockholder, enforceable against such Stockholder in accordance with its terms, subject to (i) laws of general application relating to bankruptcy, insolvency and the relief of debtors, and (ii) rules of law governing specific performance, injunctive relief and other equitable remedies. There is no beneficiary or holder of a voting trust certificate or other interest of any trust of which the Stockholder is a trustee whose consent is required for the execution and delivery of this Agreement or the consummation by the Stockholder of the transactions contemplated hereby.

ARTICLE II

GRANT OF PROXY

Section 2.01 Grant of Proxy.

Section 4.09 Governing Law; Waiver of Jury Trial; Jurisdiction.
