(c) The term "Title Defect" as used herein shall mean any material encumbrance or defect in Seller's title to the Interests (expressly excluding Permitted Encumbrances), that renders Seller's title to the Interests less than Defensible Title.

(b) In the event a third party exercises an applicable preferential right to purchase any of the Interests prior to the Closing Date, the affected Interests shall be removed from this Agreement and the Purchase Price shall be adjusted by the Allocated Value of the Interests. In the event such third party fails or refuses to close on such preferential right within sixty (60) days of the date of such third party's exercise of its preferential right, then Buyer shall purchase such affected Interests covered by the preferential right for its Allocated Value as of the Effective Time and the closing for such transaction shall take place on a mutually acceptable date not more than thirty (30) days following such failure or refusal. If any preferential right to purchase any portion of the Interests is exercised after the Closing Date, such affected portion of the Interests shall not be treated as a Title Defect, and no adjustment shall be made on account of such exercise. All Interests that are subject to preferential rights to purchase that have not been exercised as of such date and time shall be conveyed to Buyer at the Closing. If any such preferential right is exercised after such date and time, Buyer agrees to convey such affected Interests to the party exercising such right on the same terms and conditions under which Seller conveyed such Interests to Buyer. Buyer shall retain all amounts paid by the party exercising such preferential right to purchase. In the event of such exercise, Buyer shall prepare a form of conveyance of such interests from Buyer to such exercising party, such conveyance to be in form and substance as provided in this Agreement, except that such conveyance shall be made free and clear of all liens, encumbrances, royalty interests, production payments and other charges or defects created by, through or under Buyer. Buyer agrees to hold harmless and indemnify Seller regarding any claims made by third parties claiming preferential rights subsequent to Closing. 5.4 CASUALTY LOSS.

Seller shall, at the Closing, pay to Buyer all sums paid to Seller by third parties by reason of the destruction or taking of such Interests to be assigned to Buyer, and shall assign, transfer and set over unto Buyer all of the right, title and interest of Seller in and to any unpaid awards or other payments from third parties arising out of the destruction, taking or pending or threatened taking as to such Interests to be conveyed to Buyer. Seller shall not voluntarily compromise, settle or adjust any material amounts payable by reason of any material destruction, taking or pending or threatened taking as to the Interests to be conveyed to Buyer without first obtaining the written consent of Buyer. 6.

Unless the parties agree otherwise in writing and subject to the conditions stated in this Agreement, the consummation of the transactions contemplated hereby (the "Closing") shall be held on or before June 30, 1999. The date the Closing actually occurs is called the "Closing Date." 8.2 PLACE OF CLOSING. The Closing shall be held at the offices of Seller in Houston, Texas. 8.3 CLOSING OBLIGATIONS. At the Closing the following events shall occur, each being a condition precedent to the others and each being deemed to have occurred simultaneously with the others: (a) Seller and Buyer shall execute, acknowledge and deliver: an assignment, bill of sale and conveyance (in sufficient counterparts to facilitate recording) in substantially the form of EXHIBIT "B" hereto conveying to Buyer the Interests; and (b) Seller and Buyer shall execute and deliver a settlement statement, prepared in accordance with this Agreement and generally accepted accounting principles (the "Preliminary Settlement Statement") prepared by Seller that shall set forth the Preliminary Purchase Price and each adjustment and the calculation of such adjustments used to determine such amount. Seller shall provide Buyer with the Preliminary Settlement Statement three business days prior to Closing for Buyer's review and approval. The term "Preliminary Purchase Price" shall mean the Purchase Price, adjusted as provided in Section 2.2, using for such adjustments the best information then available. 17 21 (c) Buyer shall deliver to Seller the Preliminary Purchase Price by direct bank or wire transfer in immediately available federal funds. (d) Seller and Buyer shall execute, acknowledge and deliver transfer orders or letters in lieu thereof directing all purchasers of production to make payment to Buyer of proceeds attributable to production from the Interests assigned to Buyer. (e) Seller shall prepare such notices to third-party operators of the change in ownership of the Interests from Seller to Buyer and such notices of change in operatorship for those Seller-operated Wells for which Buyer has taken over operations as are reasonable and customary in the industry. Further, Seller shall deliver to Buyer executed copies of Change of Operator forms for signature and Seller shall promptly file the same as soon as practical after closing but in no event later than 5 days from closing. 9. OBLIGATIONS AFTER CLOSING. 9.1 POST-CLOSING ADJUSTMENT PROCEDURE. (a) As soon as practicable after the Closing Date, but no later than 90 days after the Closing Date, Seller shall prepare and deliver to Buyer, in accordance with this Agreement and generally accepted accounting principles, a statement (the "Final Settlement Statement") setting forth each adjustment or payment that was not finally determined as of the Closing Date and showing the calculation of such adjustments. Within fifteen days after receipt of the Final Settlement Statement, Buyer shall deliver to Seller a written report containing any changes that Buyer proposes be made to the Final Settlement Statement. The parties shall undertake to agree with respect to the amounts due pursuant to such post-closing adjustment no later than fifteen days after Seller has received Buyer's proposed changes. The date upon which such agreement is reached or upon which the "Final Purchase Price" is established, shall be called the "Final Settlement Date." If (i) the Final Purchase Price is more than the Preliminary Purchase Price, Buyer shall pay in immediately available federal funds the amount of such difference to Seller or to Seller's account (as designated by Seller), or (ii) the Final Purchase Price is less than the Preliminary Purchase Price, Seller shall pay in immediately available federal funds the amount of such difference to Buyer or to Buyer's account (as designated by Buyer). Payment by Buyer or Seller shall be made within five days after the Final Settlement Date. (b) The parties will use their best efforts to update (to the Effective Time) the volume amounts listed on EXHIBIT "E" within sixty (60) days from the Closing Date. If the gas imbalance of a Well indicated on EXHIBIT "E" changes or additional Wells are added as a result of this update, the parties will make the appropriate payments to one another on the final Settlement Date based on a value of $1.50 per MCF less applicable royalties and taxes to reflect the updated imbalance volume and the resulting balancing value for the Well. If Seller and a third party operator disagree as to the amount of any imbalance, 18 22 Buyer and Seller shall mutually agree to an amount. If a Well is deleted from the transaction pursuant to some other provision of this Agreement, the Well shall also be deleted from any adjustments pursuant to this paragraph. After the Final Settlement Date, there shall be no further adjustment made as to gas imbalance on any of the Wells listed on EXHIBIT "E". 9.2 FILES AND RECORDS. Within thirty days after the Closing Date, Seller shall make available to Buyer originals of all of Seller's files and records relating to the Interests in the format maintained by Seller, but excluding any records or data that cannot be transferred because of prior contractual restrictions. Buyer shall retain and make available to Seller for seven full calendar years following the Closing Date, in Buyer's office during normal business hours, files and records relating to the Interests. Seller shall retain division order files until the last day of the month in which Seller retains disbursement responsibilities. 9.3 POST-CLOSING ADMINISTRATIVE ACCOUNTING RESPONSIBILITIES. To the extent Seller is presently involved in the administration of the Interests, Seller shall retain the obligation and responsibility for the administration of the Interests for the period ending on the Closing Date. However, Seller and Buyer recognize that Buyer's obligation to immediately assume administrative accounting responsibilities for the Interests upon Closing may be impractical and will present certain difficulties for both Seller and Buyer in regards to transfer of such administrative responsibilities, timely and proper revenue distributions, payment of expenses, joint interest billings and the rendition of post-closing settlement statements. Therefore, to facilitate a convenient and proper transfer of the administrative accounting responsibilities relating to the Interests, Seller and Buyer agree the administrative duties will be transferred from the Seller to the Buyer in the following manner: (a) Revenue Distributions: (1) Seller shall retain the responsibility for distribution of revenues attributable to production prior to Closing. Such distribution shall be conducted by Seller through Seller's sales cutoff during the second month following the month of Closing. (2) In the event Seller should receive revenues subsequent to the Seller's cutoff for its last revenue distribution, as described above, unless such revenues are for production prior to the Effective Time, then Seller shall promptly remit such revenues to Buyer as soon as is practical, and Buyer shall be responsible for distributing all such amounts, including distributions to royalty owners. 19 23 (3) In the event Buyer should receive revenues for production from the Interests for the production period prior to Effective Time, then Buyer shall promptly remit such revenues, net of severance taxes and royalties, to Seller within five (5) business days. (4) It is understood that Seller will not undertake to change its distribution master files for purposes of the above discussed revenue distributions until after the Closing Date, and any information on the Interests received by Seller related to master file changes subsequent to the Closing Date will be remitted to the Buyer as soon as is practical. (b) Payment of Expenses and Joint Interest Billings: (1) Seller shall retain, subject to the terms hereof, the responsibility for the payment of all invoices, expenses and joint interest billings for such expenses, including COPAS overhead charges for invoices received and vouchered through Closing after which Buyer shall assume all responsibility. (2) All invoices, expenses and joint interest billings for such expenses received subsequent to Closing Date and attributable to the period after the Effective Date will be forwarded to the Buyer as received by the Seller. 9.4 FURTHER ASSURANCES. After Closing, Seller and Buyer shall execute, acknowledge and deliver or cause to be executed, acknowledged and delivered such instruments, and shall take such other action as may be necessary or advisable to carry out their obligations under this Agreement and under any document, certificate or other instrument delivered pursuant hereto. 9.5 ASSUMPTION OF OBLIGATIONS. (a) EXCEPT AS PROVIDED IN SECTION 6.1 ABOVE, ASSIGNMENT OF THE INTERESTS TO BUYER SHALL CONSTITUTE AN EXPRESS ASSUMPTION BY BUYER OF, AND BUYER EXPRESSLY AGREES TO PAY, PERFORM, FULFILL AND DISCHARGE ALL CLAIMS, COSTS, EXPENSES, LIABILITIES AND OBLIGATIONS (INCLUDING BUT NOT LIMITED TO ENVIRONMENTAL CLAIMS AND ENVIRONMENTAL CONDITIONS) ACCRUING OR RELATING TO THE OWNING, DEVELOPING, EXPLORING, OPERATING AND MAINTAINING OF THE INTERESTS CONVEYED TO BUYER AT THE CLOSING, INCLUDING WITHOUT LIMITATION, ALL VIOLATIONS OF ENVIRONMENTAL LAW AND ALL OBLIGATIONS ARISING UNDER OPERATING AGREEMENTS, PRODUCT SALES AGREEMENTS AND THE OTHER AGREEMENTS COVERING OR RELATING TO THE INTERESTS, REGARDLESS OF THE NEGLIGENCE OF SELLER. 20 24 (b) BUYER ACKNOWLEDGES THAT SELLER HAS NOT MADE, AND SELLER HEREBY EXPRESSLY DISCLAIMS AND NEGATES, ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, RELATING TO THE CONDITION OF ANY REAL OR IMMOVABLE PROPERTY, PERSONAL OR MOVABLE PROPERTY, EQUIPMENT, INVENTORY, MACHINERY AND FIXTURES CONSTITUTING PART OF THE INTERESTS INCLUDING, WITHOUT LIMITATION, (i) ANY IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY, (ii) ANY IMPLIED OR EXPRESS WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE, (iii) ANY IMPLIED OR EXPRESS WARRANTY OF CONFORMITY TO MODELS OR SAMPLES OF MATERIALS, (iv) ANY RIGHTS OF BUYER UNDER APPROPRIATE STATUTES TO CLAIM DIMINUTION OF CONSIDERATION OR RETURN OF THE PURCHASE PRICE, (v) ANY IMPLIED OR EXPRESS WARRANTY OF FREEDOM FROM PATENT OR TRADEMARK INFRINGEMENT, (vi) ANY IMPLIED OR EXPRESS WARRANTY REGARDING ENVIRONMENTAL LAWS, THE RELEASE OF MATERIALS INTO THE ENVIRONMENT INCLUDING NATURALLY OCCURRING RADIOACTIVE MATERIAL, OR PROTECTION OF THE ENVIRONMENT OR HEALTH, IT BEING THE EXPRESS INTENTION OF BUYER AND SELLER THAT THE REAL OR IMMOVABLE PROPERTY, PERSONAL OR MOVABLE PROPERTY, EQUIPMENT, INVENTORY, MACHINERY AND FIXTURES SHALL BE CONVEYED TO BUYER AS IS AND IN THEIR PRESENT CONDITION AND STATE OF REPAIR.

FROM AND AFTER THE CLOSING DATE, BUYER AND SELLER SHALL INDEMNIFY EACH OTHER AS FOLLOWS: (a) SELLER SHALL DEFEND, INDEMNIFY AND SAVE AND HOLD HARMLESS BUYER, ITS OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS, AGAINST ALL LOSSES, DAMAGES, CLAIMS, DEMANDS, SUITS, COSTS, EXPENSES, LIABILITIES AND SANCTIONS OF EVERY KIND AND CHARACTER, INCLUDING WITHOUT LIMITATION REASONABLE ATTORNEYS' FEES, COURT COSTS AND COSTS OF INVESTIGATION, WHICH ARISE FROM OR IN CONNECTION WITH ANY BREACH BY SELLER OF THIS AGREEMENT.
