ARTICLE I

REPURCHASE OF SHARES

Section 1.1 Repurchase of Shares. The Holder hereby agrees to sell the Shares to the Company, and the Company hereby agrees to purchase the Shares from the Holder at the Purchase Price, subject to the terms and conditions of this Agreement.

Section 1.2 Closing. The closing of the purchase and sale of the Shares to the Company by the Holder (the “Closing”) shall occur on the Effective Date. The Closing will take place remotely by electronic exchange of signatures. At the Closing: (i) the Company shall deliver to the Holder the Purchase Price for the Shares, in cash, by same day wire transfer, or by check, and (ii) the Holder shall deliver to the Company the certificate or certificates, if any, evidencing the Shares, duly endorsed for transfer in blank or accompanied by a duly executed stock power in the form attached hereto as Exhibit A.

Section 1.3 Representations by the Holder. In connection with the Closing, the Holder represents and warrants to the Company as follows:

(a) Title to the Shares. The Holder is the sole lawful record and beneficial owner of the Shares and has good, valid and marketable title to the Shares free and clear of all liens, charges, security interests, encumbrances, claims and restrictions of any kind. There are no outstanding options, warrants, rights, calls, agreements or commitments to which the Holder is party with respect to any of the Shares.

(b) Authorization. The Holder has the full, absolute and unrestricted right, power and authority to sell, transfer and assign the Shares to the Company pursuant to this Agreement and to enter into this Agreement. No consent, approval or authorization of or notice to any third party is necessary in connection with the sale, purchase or delivery of the Shares, and the performance by the Holder of its obligations and duties hereunder does not and will not violate any agreement, instrument, or obligation to which the Holder is a party or by which either the Holder or the Shares are otherwise bound. This Agreement constitutes a valid and legally binding obligation of the Holder, enforceable against the Holder in accordance with its terms.

(c) No Action. There are no actions, proceedings or investigations pending or, to the Holder’s knowledge, threatened against or involving the Holder or the Shares that questions the transactions contemplated by this Agreement or could prevent the consummation thereof, and, to the Holder’s knowledge, there is no basis for any such action, proceeding, or investigation.

(d) Access to Information. The Holder is aware of the Company’s business affairs and financial condition and has received all information that the Holder considers necessary or appropriate about the Company and the sale of the Shares to the Company to reach an informed and knowledgeable decision to sell the Shares to the Company.

(e) Experience. The Holder hereby represents and warrants that the Holder has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of selling the Shares.

(f) Acknowledgement. The Holder acknowledges that it has not relied upon any person or entity (including the Company or any of the Company’s officers, managers, members, or affiliates, or their respective representatives) in making its decision to sell the Shares. The Holder acknowledges that the Company has not made any representations to the Holder, including regarding the advisability of the decision to enter into this Agreement and to sell the Shares or regarding the potential past, present, or future value of the Shares. The Holder understands that the Company’s plans for the future, if successful, may result in the Company’s capital stock becoming significantly more valuable and that the future value of the Shares could exceed the amounts the Holder will receive under this Agreement, and the Holder acknowledges that by selling the Shares hereunder, the Holder is foregoing any future appreciation of the value of the Shares and is selling the Shares of the Holder’s own free will and choice.

(g) Further Assurances. The Holder covenants to make, execute, acknowledge and deliver all such other instruments, certificates, letters and other writings and amendments to this Agreement and, in general, to take such further action as the Company, in its sole and absolute discretion, may consider necessary or proper in connection with or to carry out the repurchase of the Shares under this Agreement.
