PURCHASE PRICE. 2.1 Purchase Price. The purchase price for the Assets is Five Hundred Million Dollars ($500,000,000.00) (the "Purchase Price"), subject to the adjustments provided for in this Agreement. The Purchase Price shall be paid as follows: Buyer shall pay to Seller a deposit ("Deposit") of five percent (5%) of the Purchase Price upon execution of this Agreement and shall pay the balance of the Purchase Price at Closing. The Deposit shall be refundable to Buyer in the event the contemplated sale of the Assets fails to close unless the failure to close is due to the default of Buyer. 2.2 Adjustments to the Purchase Price. For purposes of determining the Post-Closing Adjustments provided for in Section 4, appropriate adjustments to the Purchase Price shall be made as follows: (A) The Purchase Price shall be adjusted upward by: (i) any amount determined to be due Seller pursuant to Section 4.2; (ii) Taxes paid by Seller attributable to the period after April 1, 2003 ("Effective Time") which are apportioned to Buyer pursuant to Section 4.3. (iii) an amount equal to the costs, expenses and other expenditures (whether capitalized or expensed) paid by Seller in accordance with this Agreement that are attributable to the Assets for the period from 9:00 a.m. (Central Time) on April 1, 2003 (the "Effective Time") to the Closing Date; (iv) all amounts owed to Seller by third parties with respect to any Imbalances existing at the Effective Time, such amounts to be determined for Imbalances by multiplying the Imbalance volume by $1.50 per mcf for Well Imbalances and $3.00 per mcf for pipeline imbalances; (v) an amount equal to the amount of proceeds derived from the sale of Oil and Gas, actually received by Buyer and directly attributable to the Wells which are, in accordance with generally accepted accounting procedures, attributable to the period of time prior to the Effective Time. 3 (vi) interest on the Base Purchase Price in an amount equal to the lesser of (A) the prime rate of Chase Manhattan Bank plus two percent (2%) or (B) the maximum legal rate (the "Interest"), with such Interest accruing from the scheduled Closing Date set forth in Section 3.1 until the actual Closing Date to the extent that the conditions set forth in Article 11 have been satisfied or waived and Buyer refuses or otherwise fails to proceed to Closing on or before the scheduled Closing Date set forth in Section 3.1, other than as a result of Seller's breach of this Agreement; and (vii) any other amount agreed upon in writing by Seller and Buyer. (B) The Purchase Price shall be adjusted downward by: (i) an amount equal to the amount of proceeds derived from the sale of Oil and Gas, actually received by Seller and directly attributable to the Wells which are, in accordance with generally accepted accounting procedures, attributable to the period of time from and after the Effective Time; (ii) an amount equal to all expenditures, liabilities and costs (whether capitalized or expensed) relating to the Assets (other than Taxes related to the Assets) that are unpaid as of the Closing Date and assessed for or attributable to periods of time prior to the Effective Time; (iii) all amounts owed by Seller to third parties with respect to any Imbalances existing as of the Effective Time, such amounts to be determined for Imbalances by multiplying the Imbalance volume by $1.50 per mcf for well imbalances and $3.00 per mcf for pipeline imbalances; (iv) Exercised Preferential Rights as determined pursuant to Section 9.3 and Casualty Losses as determined pursuant to Section 15.1; and (v) Taxes attributable to the period beginning on the Closing Date and ending on the Effective Time which are apportioned to Seller pursuant to Section 4.3. (vi) any other amount agreed upon in writing by Seller and Buyer. The term "Imbalance" means any Oil and Gas production and pipeline imbalance existing as of the Effective Time with respect to any of the Assets, together with any related rights or obligations as to future cash and/or gas or product balancing, as a result of, in the case of production imbalances, Seller having taken and sold for Seller's account cumulative production which is greater or less than Seller's share in cumulative production. (C) Seller shall have the right to collect any receivable, refund or other amounts associated with periods prior to the Effective Time to the extent Seller has not 4 received credit for such amounts from Buyer. To the extent that Buyer collects any such receivable, refund or other amounts, then Buyer shall promptly remit any such amounts to Seller. 2.3 Allocation. The Purchase Price shall be allocated to the Assets as set forth in Exhibit 2.3. Seller and Buyer covenant and agree that the values allocated to various portions of the Assets, which are set forth on Exhibit 2.3 (singularly with respect to each item, the "Allocated Value" and collectively, the "Allocated Values"), shall be binding on Seller and Buyer and shall be used for the purposes of adjusting the Purchase Price pursuant to Sections 9.3 (relating to Preferential Rights) and 15.1 (relating to Casualty Losses) and is not intended as a measure of value for any other purpose. 2.4 Allocation For Tax Purposes.

Seller and Buyer agree that each shall furnish the other a copy of Form 8594 (Asset Acquisition Statement under Section 1060) proposed to be filed with the Internal Revenue Service by such Party or any affiliate thereof within ten (10) days prior to the filing of such form with the Internal Revenue Service. 3.

For purposes of this Agreement, "Tax" or "Taxes" shall mean all ad valorem, property, production, excise, net proceeds, severance and all other taxes and similar obligations assessed against the Assets or based upon or measured by the ownership of the Assets or the production of hydrocarbons or the receipt of proceeds therefrom, other than income taxes. All Taxes based on or attributable to the ownership of, or based on production of hydrocarbons shall be deemed attributable to the period during which such Taxes are assessed. With respect to the Assets, all Taxes shall be prorated between Buyer and Seller as of the Effective Time for all taxable periods that include the Effective Time. Accordingly, for the purpose of apportioning the liability for Taxes and the resulting Purchase Price adjustment pursuant to Section 2, (i) Buyer shall be responsible for all Taxes related to the Assets that are attributable to the period of time after the Effective Time and (ii) Seller shall be responsible for all Taxes related to the Assets that are attributable to the period of time on or before the Effective Time. 6 4.3(B) Apportionment of Taxes/Purchase Price Adjustment. Based on the best current information available as of Post-Closing, the pro-ration of Taxes shall be made between the Parties as an adjustment to the Purchase Price pursuant to Section 2 and that pro-ration shall be deemed to be a final settlement between the Parties with respect to Taxes. Accordingly, after Post-Closing. 4.3(C) Tax Reports and Returns. For the tax period in which the Effective Time occurs, Seller agrees to immediately forward to Buyer any such tax reports and returns received by Seller after Closing and provide Buyer with appropriate information which is necessary for Buyer to file any required tax reports and returns related to the Assets. Buyer agrees to file all tax returns and reports applicable to the Assets that are required to be filed after the Closing, and pay all required Taxes payable with respect to the Assets. 4.3(D) Sales Taxes. Buyer shall be liable for and shall indemnify Seller for any sales and use taxes, conveyance, transfer and recording fees and real estate transfer stamps or taxes that may be imposed on any transfer of the Assets pursuant to this Agreement. If required by applicable law, Seller shall, in accordance with applicable law, calculate and remit any sales of similar taxes that are required to be paid as a result of the transfer of the Assets to Buyer and Buyer shall promptly reimburse Seller therefore. If Seller receives notice that any sales and/or use taxes are due, Seller shall promptly forward such notice to Buyer for handling. 4.4 Post-Closing Adjustments. (A) Seller shall prepare and deliver to Buyer not later than July 11, 2003 a statement of adjustments to the Purchase Price (the "Post- Closing Adjustment Statement") which shall be based on the actual income and expenses attributable to the Assets.

(B) On or before July 28, 2003, Buyer shall deliver to Seller a written statement describing in reasonable detail its objections (if any) to any amounts or items set forth on or omitted from the Post-Closing Adjustment Statement. If Buyer does not raise objections within such period, then the Post-Closing Adjustment Statement shall become final and binding upon the Parties at the end of such period. (C) If Buyer raises objections, the Parties shall negotiate in good faith to resolve any such objections. If the Parties are unable to resolve any disputed item by August 15, 2003 any such disputed item shall be submitted to a nationally recognized independent accounting firm mutually agreeable to the Parties who shall be instructed to resolve such disputed item within thirty (30) days. The resolution of disputes by the accounting firm so selected shall be set forth in writing and shall be conclusive, binding and non-appealable upon the Parties and the Post-Closing Adjustment Statement shall become final and binding upon the Parties on the date of such resolution. The fees and expenses of such accounting firm shall be paid one-half by Buyer and one-half by Seller. (D) After the Post Closing Adjustment Statement has become final and binding on the Parties, Seller or Buyer, as the case may be, shall pay to the other such sums as are due to settle accounts between the Parties due to final adjustments to the Purchase Price. 4.5 Suspended Funds. No later than June 30, 2003, Seller shall provide to Buyer a computer readable listing showing all proceeds from production attributable to the Leases which are currently held in suspense and shall transfer to Buyer all of those suspended proceeds without deducting any receivables, provided that Buyer agrees to use its best efforts to recoup and remit to Seller such receivables out of proceeds attributable to such accounts receivable, if any, after recoupment of amounts such party may owe Buyer. BUYER SHALL BE RESPONSIBLE FOR PROPER DISTRIBUTION OF ALL THE SUSPENDED PROCEEDS, TO THE EXTENT TURNED OVER TO IT BY SELLER, TO THE PARTIES LAWFULLY ENTITLED TO THEM AND ANY CLAIMS RELATED THERETO EXCEPT FOR ANY STATUTORY INTEREST AND PENALTIES DUE THEREON WHICH SHALL BE SELLER'S RESPONSIBILITY, AND BUYER HEREBY AGREES TO INDEMNIFY, DEFEND AND HOLD HARMLESS SELLER FROM AND AGAINST ANY AND ALL LOSSES AS DEFINED BELOW ARISING OUT OF OR RELATING TO THOSE SUSPENDED PROCEEDS. 4.6 Audit Adjustments. Seller retains all rights to adjustments resulting from any operating agreement and other audit claims asserted against third party operators on transactions occurring prior to the Effective Time (which includes Buyer, if applicable). Any credit received by Buyer pertaining to such an audit claim shall be paid to Seller within thirty (30) days after receipt. 4.7 Tax Refunds. Refunds of Taxes paid or payable with respect to or attributable to the Assets shall be promptly paid as follows (or to the extent payable but not paid due to offset against other Taxes shall be promptly paid by the Party receiving the benefit of the offset as follows): (i) to Seller if attributable to Taxes with respect to any Tax year or portion thereof ending on or before the Effective Time; and (ii) to Buyer if attributable to Taxes with respect to any Tax year or portion thereof beginning from and after the Effective Time. 4.8 Cooperation.

Physical changes in or under the Assets or adjacent lands may have occurred as a result of such uses. The 10 Assets also may contain buried pipelines and other equipment, whether or not of a similar nature, the locations of which may not now be known by Seller or be readily apparent by a physical inspection of the Assets. Buyer understands that Seller does not have the requisite information with which to determine the exact nature or condition of the Assets nor the effect any such use has had on the physical condition of the Assets. Pursuant to the Safe Water Drinking and Toxic Enforcement Act of 1986, Buyer is hereby notified and assumes the risk that detectable amounts of chemicals known to cause cancer, birth defects and other reproductive harm may be found in, on or around the Assets. Buyer shall assume the risk that the Assets may contain waste or contaminants and that adverse physical conditions, including the presence of waste or contaminants, may not have been revealed by Buyer's investigation, if any. All responsibility and liability related to disposal, spills, waste or contamination on or below the Assets shall be transferred from Seller to Buyer. In addition, Buyer acknowledges that some oil field production equipment located on the Assets may contain asbestos and/or naturally occurring radioactive material ("NORM"). In this regard, Buyer expressly understands that NORM may affix or attach itself to inside of wells, materials and equipment as scale or in other forms, and that wells, materials and equipment located on the Assets described herein may contain NORM and that NORM-containing materials may be buried or have been otherwise disposed of on the Assets. Buyer also expressly understands that special procedures may be required for the removal and disposal of asbestos and NORM from the Assets where they may be found, and that Buyer assumes all liability when such activities are performed. 5.4 Buyer's Activities on the Assets and on Seller's Premises Until Closing. Buyer waives and releases all claims against Seller, its parent and subsidiary companies, and each of their respective directors, officers, employees, agents and other representatives and their successor and assigns (collectively, the "Seller Group"), for injury to or death of persons, or damage to property, arising in any way from the exercise of rights granted to Buyer with respect to the Assets or the activities of Buyer or its employees, agents or contractors on the Assets or on Seller's premises. BUYER SHALL INDEMNIFY THE SELLER GROUP AGAINST AND HOLD EACH AND ALL OF SAID INDEMNITEES HARMLESS FROM ANY AND ALL LOSSES WHATSOEVER ARISING OUT OF (I) ANY AND ALL STATUTORY OR COMMON LAW LIENS OR OTHER ENCUMBRANCES FOR LABOR OR MATERIALS FURNISHED IN CONNECTION WITH SUCHACTIVITIES AS BUYER MAY CONDUCT WITH RESPECT TO THE ASSETS; AND (II) ANY INJURY TO OR DEATH OF PERSONS OR DAMAGE TO PROPERTY OCCURRING IN, ON OR ABOUT THE ASSETS AS A RESULT OF SUCH EXERCISE OR ACTIVITIES. 6.
