(b)The Shares shall be issued in book-entry form unless otherwise requested by a Seller. Certificates, if any, representing the Shares will bear legends referring to the U.S. securities laws. Each Seller acknowledges and agrees for the benefit of Purchaser that no Shares may be issued to such Seller pursuant to this Agreement in the absence of the receipt by Purchaser or its duly appointed stock transfer agent, at least two (2) business days prior to the issuance of the Shares, of a completed IRS Form W-9 or IRS Form W-8, as the case may be, duly executed by such Seller.

4.Closing. The Closing shall take place at the offices of Xxxxx Xxxxxx & Xxxxxx LLP, 0000 00xx Xxxxxx, Xxxxx 000, Xxxxxx, Xxxxxxxx 00000, on the second (2nd) business day after the satisfaction or waiver of the conditions set forth in Section 7 (other than conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions), or at such other place, date and time as Purchaser and Sellers shall agree. The date on which the Closing actually occurs is referred to as the “Closing Date.”

5.Representations, Warranties and Covenants of Sellers. Each Seller represents and warrants to Purchaser as follows:

(a)The Contingent Production Payments are owned beneficially, entirely and completely by Seller in the amounts set forth opposite his, her or its name on Schedule A hereto, free and clear of any and all Liens. Seller has not granted any rights, warrants, options, subscriptions, agreements or commitments to sell or acquire the Contingent Production Payments, any part thereof, or any right or benefit related thereto to any party other than Purchaser pursuant to this Agreement. Seller agrees to the Deposit to be paid and the Shares to be issued in exchange for the Contingent Production Payments provided for in Section 2 and acknowledges and agrees that the Deposit and Share Consideration are fair and reasonable to Sellers and represent the sole amounts to be received by Sellers in the proportions set forth on Schedule A hereto, in

(b)Seller has the full and complete power, authority and legal capacity to enter into and consummate the transactions contemplated by this Agreement. This Agreement has been duly executed and delivered (and in the case of JTWI Corporation and Pebcor Enterprises, LLC, duly approved and authorized) by Seller and (assuming due authorization, execution and delivery by Purchaser) constitutes the valid and binding agreement of Seller, enforceable in accordance with its terms. Seller’s execution and delivery of this Agreement and the consummation of the transactions contemplated herein do not violate, and are not restricted by, any agreement or obligation of Seller, nor will they result in any violation of or be in conflict with any document, instrument, judgment, decree, order, statute, rule or regulation applicable to Seller.

(c)No consents, approvals or filings, other than such as have heretofore been obtained or made, are required to authorize or consummate the execution and delivery of this Agreement by Seller or the sale of the Contingent Production Payments as herein contemplated.

(d)No suit, action, or legal, administrative, arbitration or other proceeding or governmental investigation is pending or, to Seller’s knowledge, threatened against Seller or related to the Contingent Production Payments where such action would reasonably be expected to have an adverse effect on the transactions contemplated by, or the consummation of the transaction provided for in, this Agreement.

(e)Seller is not a director, officer or holder of 5% or more of the Common Stock or voting power outstanding of Purchaser.

(f)In exchange for the Contingent Production Payments, Seller is acquiring, among other things, the Shares in the proportion set forth opposite his, her or its name on Schedule A hereto solely for his, her or its own account for investment purposes and not with a view to, or for offer or sale in connection with, any distribution thereof. Seller acknowledges that the Shares are not registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws, and that the Shares may not be transferred or sold except pursuant to the registration provisions of the Securities Act or pursuant to an applicable exemption therefrom and subject to state securities laws and regulations, as applicable. Seller is able to bear the economic risk of holding the Shares in the proportion set forth opposite his, her or its name on Schedule A hereto for an indefinite period (including total loss of its investment), and has sufficient knowledge and experience in financial and business matters so as to be capable of evaluating the merits and risk of his, her its investment.

(b)No consents, approvals or filings, other than such as have heretofore been obtained or made, are required to authorize or consummate the execution and delivery of this Agreement by Purchaser or the purchase of the Contingent Production Payments as herein contemplated.

such other acts and things as any Seller may reasonably request for the purpose of carrying out the intent of this Agreement.
