The Bellows Lease does not cover 100% of the mineral fee estate and three (3) additional leases have been negotiated with the remaining mineral fee owners, being Main Plaza Corporation, Jarret B. Meuth and William R. Meuth, Jr. (collectively, the "Mineral Owner Leases"). The Bellows Lease and the Mineral Owner Leases are collectively referred to as the "Leases". Davidson shall bear the initial acquisition costs of the Mineral Owner Leases at its sole expense, not subject to reimbursement. 1.Interests to be Purchased/Purchase Price.

The purchase price for the TTEP Initial Well Interest shall be (i) TTEP's agreement to pay 100% (One Hundred Percent) of the actual costs up to the dollar limit ("Dollar Limit") stated in the Approval for Expenditure ("AFE") for drilling, testing, stimulating, completing and equipping (including tie in to sales lines) the Initial Well as a producing well through the tanks (if an oil well) or through the pipeline connection (if a gas well), as specified in the AFE, unless the election is made to plug and abandon the Initial Well, in which case the purchase price for the TTEP Initial Well Interest shall be the actual costs of drilling, testing, and plugging the Initial Well, plus any costs related to surface restoration surrounding the Initial Well which is required by the Bellows Lease. Any additional costs over the Dollar Limit shall be paid 70% (Seventy Percent) by TTEP and 30% (Thirty Percent) by Davidson. The remaining 30% (Thirty Percent) working interest in the Spacing Unit shall be retained by Davidson and Trust. The net revenue interest ("NRI") which shall be attributable to holders of all of the working interest shall be not less than 75% (Seventy Five Percent). All reasonable efforts will be made to spud the Initial Well by January 31, 2006, subject to drilling rig and other long lead time items' availability. The parties agree that the drilling operations shall be conducted on the Initial Well by Alamo Operating Company, L.C.

(d) The funds deposited by TTEP shall be used solely for the purposes set forth in the AFE agreed by the parties, which shall include road work, site preparation, drilling of a water well and drilling, completing and equipping (or plugging and surface restoration, if applicable) on the Leases.
