ARTICLE I
Transfers of Various Ownership Interests

The parties hereby agree, as promptly as reasonably practicable, to undertake the following transactions in the order set forth in this Article.

Section 1.1 Tax Distribution.  Prior to the transfer of ownership interests to Newco pursuant to Section 1.2, Xxxxxx Ltd. will estimate its “Presumed Partnership Tax Liability” (as defined in Section 5.8 of the Third Amended and Restated Agreement of Limited Partnership of Xxxxxx Ltd., dated January 1, 2004 (“Xxxxxx Ltd.’s Partnership Agreement”)) as of the Closing (as hereinafter defined) and make a tax distribution in accordance with such Section 5.8 of Xxxxxx Ltd.’s Partnership Agreement to allow the Owners to pay tax on their direct or indirect share of Xxxxxx Ltd.’s undistributed taxable income for the short taxable year ending on the Closing.  Following this distribution by Xxxxxx Ltd., Management and SOP will make similar tax distributions to allow their Owners to pay tax on their direct or indirect shares of Management’s and SOP’s undistributed taxable income for the short taxable year ending on the Closing.

Section 1.2 Transfer of Ownership Interests to Newco.  Pursuant to the form of Assignment attached hereto as Exhibit A or the form of Assignment and Stock Power attached hereto as Exhibit B, as applicable, each Owner will grant, contribute, transfer, assign and convey to Newco, its successors and assigns, all its right, title and interest in and to all its ownership interests in SOP, Management and Xxxxxx Ltd. as shown on Schedule I attached hereto, and Newco will accept these ownership interests as a contribution to the capital of Newco.

Section 1.3 Receipt of Stock in Newco.  The parties hereto acknowledge that the transactions described in this Agreement constitute “Capital Transactions” and the proceeds thereof constitute “Capital Proceeds” as defined in Xxxxxx Ltd.’s Partnership Agreement.  In exchange for the transfers described above, Newco will issue shares of Newco common stock to each Owner assuming a relative value for each Owner’s ownership interest and calculated in

2

accordance with Section 5.6(c) of Xxxxxx Ltd.’s Partnership Agreement (except for the preferred partnership interests in Xxxxxx Ltd. which will be purchased pursuant to Section 1.12) and in keeping with the examples of calculations shown on Schedule II attached hereto; provided, however, that the Reserved Class B Interests that were to be issued to members of management under Management’s Partnership Agreement, but have not been specifically allocated, will become reserved shares (the “Unallocated Class B Interest Shares”) retained by Newco for future issuance in accordance with the Xxxxxx Energy, Inc. 2005 Restricted Stock Plan (the “Newco Restricted Stock Plan”) and, independent of the calculation referred to above, shall be fixed in number at 226,608 shares.    The Unallocated Class B Interest Shares would otherwise have been issued to Owners of SOP by virtue of SOP’s ownership of Class B Partnership Interests in Management as of the Closing.  Shares of Newco common stock issued in exchange for the Class B Partnership Interests in Management that were granted to management employees in May 2005 and that are subject to forfeiture restrictions as of the Closing shall be issued pursuant to the Newco Restricted Stock Plan and such shares of Newco common stock shall be subject to the same forfeiture restrictions as were in effect with respect to such Class B Partnership Interests prior to the Closing.  Shares of Newco common stock issued in exchange for Class B Partnership Interests in Management that were issued to management employees prior to May 2005 shall not be subject to forfeiture and shall be fully vested.

Section 1.4 Newco Stock Incentive Plan and Restricted Stock Plan.  In connection with the transactions contemplated by this Agreement but prior to the merger of SOP described in Section 1.6 and the consummation of the Private Offering, (i) the Xxxxxx Oil Properties, Inc. 2001 Stock Incentive Plan (the “SOP Plan”) will be assumed and adopted by Newco and restated into the form of the Newco Stock Incentive Plan and (ii) the Newco Stock Incentive Plan and the Newco Restricted Stock Plan will be approved and adopted by the board of directors and the stockholders of Newco.  Upon the consummation of the Private Offering, outstanding options under the SOP Plan will be assumed by Newco and adjusted to become options to purchase shares of Newco common stock in accordance with the rules set forth in Treasury Regulations Section 1.424-1(a).

Section 1.5 Transfer of Ownership Interests in SOP by Newco.  Pursuant to the form of Assignment and Stock Power attached hereto as Exhibit B, Newco will grant, contribute, transfer, assign and convey to GP LLC, its successors and assigns, all its right, title and interest in and to 0.1% of its stock in SOP as shown on Schedule I attached hereto, and GP LLC will accept these ownership interests as a contribution to the capital of GP LLC.

Section 1.6 Merger of SOP.  Newco will take all actions necessary or convenient under the Oklahoma General Corporation Act and the Limited Partnership Act of the State of Delaware to cause SOP to merge into SOP Ltd. and the surviving entity will file an election to be treated as a corporation for federal tax purposes.

Section 1.7 Transfer of Ownership Interests in SOP Ltd. by Newco.  Pursuant to the form of Assignment attached hereto as Exhibit A, Newco will grant, contribute, transfer, assign and convey to LP LLC, its successors and assigns, all its right, title and interest in and to all its 99.9% limited partnership interests in SOP Ltd. as shown on Schedule I attached hereto, and LP LLC will accept these ownership interests as a contribution to the capital of LP LLC.

3

Section 1.8 Conversion of Management.  Newco will take all actions necessary or convenient under the Texas Revised Limited Partnership Act and the Texas Limited Liability Company Act to cause Management to convert to a Texas limited liability company.

Section 1.9 Transfer of Ownership Interests in SEM LLC by Newco to SOP Ltd. Pursuant to the form of Assignment attached hereto as Exhibit A, Newco will grant, contribute, transfer, assign and convey to SOP Ltd., its successors and assigns, all its right, title and interest in and to all its membership interests in SEM LLC as shown on Schedule I attached hereto, and SOP Ltd. will accept these membership interests.

Section 1.10 Transfer of Ownership Interests in Xxxxxx Ltd. by Newco.  Pursuant to the form of Assignment attached hereto as Exhibit A, Newco will grant, contribute, transfer, assign and convey to SOP Ltd., its successors and assigns, all its right, title and interest in and to all its limited partnership interests in Xxxxxx Ltd. as shown on Schedule I attached hereto, and SOP Ltd. will accept these ownership interests.

Section 1.11 Contribution of Proceeds by Newco.  Newco will contribute proceeds of the Private Offering (as hereinafter defined) to SOP Ltd. in an amount sufficient to make the purchase of preferred partnership interests in Xxxxxx Ltd. pursuant to Section 1.12.

Section 1.12 Purchase of Preferred Partnership Interests.  Pursuant to the form of Purchase Agreement attached hereto as Exhibit C, SOP Ltd. will purchase, and the EnCap Partners (as hereinafter defined) will sell, the preferred partnership interests in Xxxxxx Ltd. for a cash purchase price using proceeds of the Private Offering received pursuant to Section 1.11.

ARTICLE II

Section 2.1 Closing.  The closing of the transactions described in ARTICLE I (the “Closing”) will occur immediately prior to, and at the place of, the closing of the private offering of Newco common stock with proceeds and on terms satisfactory to Newco in its sole discretion (the “Private Offering”).
