ARTICLE III

REPRESENTATIONS AND WARRANTIES OF THE BUYER

The Buyer represents and warrants that the statements contained in this Article III are correct and complete as of the date of this Agreement.

Section 3.1 Organization and Good Standing. The Buyer is a limited liability company duly organized, validly existing, and in good standing under the laws of the state of Oklahoma.

Section 3.2 Power and Authority; Enforceability. This Agreement constitutes the legal, valid, and binding obligation of the Buyer, enforceable against the Buyer in accordance with its terms. The Buyer has full entity power and authority to execute and deliver this Agreement and to perform its obligations hereunder. The Buyer has taken all actions necessary to authorize the execution and delivery of this Agreement, the performance of its obligations hereunder and the consummation of the transactions contemplated hereby. This Agreement has been duly authorized, executed and delivered by, and is enforceable against, the Buyer.

Section 3.3 Investment Representations.

(a) The Buyer is an “accredited investor” as defined in Rule 501 of Regulation D under the Securities Act.

(b) The Buyer has received, has thoroughly read, is familiar with and understands the contents of this Agreement.

(c) The Buyer hereby acknowledges that an investment in the Shares involves certain significant risks. The Buyer acknowledges that there is a substantial risk that it will lose all or a portion of its investment and that it is financially capable of bearing the risk of such investment for an indefinite period of time. The Buyer has no need for liquidity in its investment in the Shares for the foreseeable future and is able to bear the risk of that investment for an indefinite period. The Buyer understands that there presently is no public market for the Shares and none is anticipated to develop in the foreseeable future. The Buyer’s present financial condition is such that the Buyer is under no present or contemplated future need to dispose of any portion of the Shares subscribed for hereby to satisfy any existing or contemplated undertaking, need or indebtedness. The Buyer’s overall commitment to investments which are not readily marketable is not disproportionate to its net worth and the investment in the Company will not cause such overall commitment to become excessive.

(d) The Buyer acknowledges that the Shares have not been and will not be registered under the Securities Act, or any state securities act, and are being sold on the basis of exemptions from registration under the Securities Act and applicable state securities acts, except those state securities acts that require registration of the Shares thereunder. Reliance on such exemptions, where applicable, is predicated in part on the accuracy of the Buyer’s representations and warranties set forth herein. The Buyer acknowledges and hereby agrees that the Shares will not be transferable under any circumstances unless the Buyer either registers the Shares in accordance with federal and state securities laws or finds and complies with an available exemption under such laws. Accordingly, the Buyer hereby acknowledges that there can be no assurance that it will be able to liquidate its investment in the Company.

(e) There are substantial risk factors pertaining to an investment in the Company. The Buyer acknowledges that it has read the information set forth above regarding certain of such risks and is familiar with the nature and scope of all such risks, including, without

limitation, risks arising from the fact that the Company is an entity with limited operating history and financial resources; and the Buyer is fully able to bear the economic risks of such investment for an indefinite period, and can afford a complete loss thereof.

(f) The Buyer has been given the opportunity to (i) ask questions of and receive answers from the Company and its designated representatives concerning the terms and conditions of the offering, the Company and the business and financial condition of the Company and (ii) obtain any additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to assist the Buyer in evaluating the advisability of the purchase of the Shares and an investment in the Company. The Buyer further represents and warrants that, prior to signing this Agreement, it has asked such questions, received such answers and obtained such information as it has deemed necessary or advisable to evaluate the merits and risks of the purchase of the Shares and an investment in the Company. The Buyer is not relying on any oral representation made by any person as to the Company or its operations, financial condition or prospects.

(g) The Buyer understands that no federal, state or other governmental authority has made any recommendation, findings or determination relating to the merits of an investment in the Company.

In the event an adjustment to the Original Certificate is required pursuant to this Article V, then the Buyer shall return the Original Certificate to the Company or its designated agent as soon as practicable upon its receipt of notice from the Company advising the Buyer of such adjustment, after which a new certificate (the “New Certificate”) shall be issued in such amount representing the adjusted number of Shares held by the Buyer. The New Certificate shall be delivered to the Buyer as soon as practicable.

ARTICLE VI

WAIVER OF LIQUIDATION DISTRIBUTIONS; REDEMPTION RIGHTS

ARTICLE VII

RESTRICTIONS ON TRANSFER

In addition to any restrictions to be contained in that certain letter agreement (the “Insider Letter”) dated as of the closing of the IPO by and between the Buyer and the Company, the Buyer agrees not to transfer, assign, sell or release or dispose of all or any part of the Shares unless, prior thereto (a) a registration statement on the appropriate form under the Securities Act and applicable state securities laws with respect to the Shares proposed to be transferred shall then be effective or (b) the Company has received an opinion from counsel reasonably satisfactory to the Company, that such registration is not required because such transaction is exempt from registration under the Securities Act and the rules promulgated by the SEC thereunder and with all applicable state securities laws.

Section 7.2 Lock-up. The Buyer acknowledges that the Shares will be subject to lock-up provisions (the “Lock-up”) contained in the Insider Letter. Pursuant to the Insider Letter, the Buyer will agree not to transfer, assign, sell or release or dispose of all or any part of the Shares until the earlier to occur of: (A) one year after the completion of the Company’s initial business combination, or (B) subsequent to the completion of the Company’s initial business combination, (i) the last sale price of the Company’s Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations) for any 20-trading days within any 30-trading day period commencing at least 150 days after the Company’s initial business combination, or (ii) the Company consummates a subsequent liquidation, merger, stock exchange or other similar transaction which results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property.

Section 7.3 Restrictive Legends. Each certificate evidencing the Shares and each certificate issued in exchange for or upon the transfer of any Shares shall be stamped or otherwise imprinted with a legend in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE TRANSFERRED IN VIOLATION OF SUCH ACT AND LAWS.”

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER SET FORTH IN THE LETTER AGREEMENT BY AND BETWEEN THE COMPANY AND THE FOUNDER. COPIES OF SUCH AGREEMENT MAY BE OBTAINED FROM THE COMPANY AT THE COMPANY’S PRINCIPAL PLACE OF BUSINESS WITHOUT CHARGE.”

ARTICLE VIII
