(c) Except as provided in Article 8, Seller shall not be obligated to segregate the Performance Deposit in a separate account, but may commingle the Performance Deposit with other funds in Seller's accounts and the Performance Deposit shall not accrue interest for the benefit of Purchaser. Likewise, in the event the Performance Deposit is refunded to Purchaser pursuant to this Agreement, Purchaser shall not be entitled to any interest on the Performance Deposit.

(e) Purchaser shall be obligated to bring funds to the Closing over and above those required to pay the Adjusted Sale Price to cover any applicable sales and gross receipts taxes on the tangible personal property. 3.02 ALLOCATION OF SALE PRICE: Purchaser shall allocate the Sale Price among the interests and operating rights in the Interests. Said allocation shall be incorporated in this Agreement as Exhibit "B". References herein to a "property" or "properties" refer to the wells, units and other subdivisions of the Real Property listed on Exhibit "B" which have an allocation of the Sale Price. ARTICLE 4. THE CLOSING The sale and purchase described in Article 2 shall take place at a Closing (the "CLOSING"), at which the Purchaser shall pay or cause to be paid to Seller the Adjusted Sale Price and any applicable closing charges and Seller shall deliver, or cause to be delivered, the conveyancing instruments referred to in Article 11 to Purchaser. The Closing shall occur at Seller's office located at 2500 CityWest Blvd., Houston 77042 at 10:00 a.m., local time on September 22, 2000, or at such other time and place to which the parties may agree in writing (the "CLOSING DATE"). The parties hereto agree that Closing may be extended for up to one month (from the original Closing Date) if Purchaser is conducting its due diligence in good faith and requests an extension at least two (2) days prior to the original Closing Date. If the original Closing Date is so extended, then the extended Closing Date shall be considered as the Closing Date. If the Closing does not occur by the Closing Date because of Seller's failure to obtain the requisite management approval in the manner described in Article 2 above, then Seller and Purchaser shall each have the right and option to terminate this Agreement upon written notice to the other party. Upon such termination, the Performance Deposit will be immediately returned to Purchaser, without interest. ARTICLE 5. TERMINATION 24.17 PURCHASER'S BREACH OR DEFAULT: IF THE PURCHASE AND SALE OF THE INTERESTS IS NOT COMPLETED AS CONTEMPLATED HEREIN BY REASON OF ANY BREACH OR DEFAULT BY PURCHASER, THEN SELLER SHALL, IN CONSIDERATION OF HAVING HELD THE INTERESTS OFF THE MARKET AND HAVING REFRAINED FROM DEALING WITH OTHERS CONCERNING THE INTERESTS AND AS LIQUIDATED DAMAGES IN LIEU OF ALL OTHER DAMAGES (AND AS SELLER'S SOLE REMEDY), RETAIN THE PERFORMANCE DEPOSIT. THE PARTIES HEREBY ACKNOWLEDGE THAT THE EXTENT OF DAMAGES TO SELLER OCCASIONED BY SUCH BREACH OR 5 EXHIBIT 10.20 DEFAULT BY PURCHASER WOULD BE IMPOSSIBLE OR EXTREMELY DIFFICULT TO ASCERTAIN AND THAT THE AMOUNT OF THE PERFORMANCE DEPOSIT IS A FAIR AND REASONABLE ESTIMATE OF SUCH DAMAGES UNDER THE CIRCUMSTANCES. 5.2 OTHER TERMINATION: IF THE PURCHASE AND SALE OF THE INTERESTS IS NOT COMPLETED BECAUSE OF A DEFAULT OR BREACH BY SELLER OR BECAUSE SELLER OR PURCHASER FAILED TO OBTAIN THE REQUISITE MANAGEMENT OR BOARD OF DIRECTOR'S APPROVAL AS REQUIRED IN SECTION 2.04 ABOVE OR ANY OTHER REASON PROVIDED HEREIN (EXCEPT SECTION 5.1), PURCHASER SHALL BE ENTITLED TO THE PROMPT RETURN OF THE PERFORMANCE DEPOSIT WITHOUT INTEREST, THE RECOVERY OF WHICH SHALL BE PURCHASER'S SOLE REMEDY AGAINST SELLER. ARTICLE 6. DUE DILIGENCE AND TITLE AND CASUALTY DEFECTS 6.01 ACCESS TO SELLER'S NON-PROPRIETARY INFORMATION: Subject to Purchaser's confidentiality obligations described in Section 24.15 below and in addition to the Proprietary Data which Seller may provide to Purchaser as described in the recitals above, Seller shall make available to Purchaser during normal business hours at Seller's offices all material non-proprietary files, records, documents and non-interpretive data in Seller's possession relating to the Interests, including but not limited to, lease, land, title and division order files (including any available abstracts of title, title opinions and title curative documents), contracts, correspondence, permitting files, engineering, production and well files and well logs. Seller shall not be obligated to perform any additional title work and Seller shall not be obligated to make any existing abstracts and title opinions current. NO WARRANTY OF ANY KIND IS MADE BY SELLER AS TO THE INFORMATION SO SUPPLIED OR WITH RESPECT TO INTERESTS TO WHICH THE INFORMATION RELATES, AND PURCHASER EXPRESSLY AGREES THAT ANY CONCLUSIONS DRAWN THEREFROM SHALL BE THE RESULT OF ITS OWN INDEPENDENT REVIEW AND JUDGMENT. 6.02 ACCESS TO SELLER'S PROPERTY: Seller shall give Purchaser or Purchaser's authorized representatives, at any reasonable time(s) before the Closing and upon adequate notice to Seller, physical access to the Real Property and Equipment included in the Interests, for the purpose of inspecting same. Such access shall be at Purchaser's sole risk, cost and expense and Purchaser shall indemnify, defend, save, discharge, release and hold harmless Seller from, and pay or reimburse Seller on a current basis for, any and all losses, liabilities, liens or encumbrances for labor or materials, claims and causes of action arising out of or in any way connected with or related to any personal injury to or death of any persons or damage to property occurring to or on the Interests as a result of Purchaser's exercise of its rights under this Section 6.02, whether latent or patent. Purchaser agrees to comply fully with the rules, regulations and instructions issued by Seller regarding the actions of Purchaser while upon, entering or leaving the Interests. Seller shall have the right at all times to participate in the preparation for and conducting of any hearing or trial related to the indemnity set forth in this Section, as well as the right to appear on its own behalf or to retain separate counsel to represent it at any such hearing or trial. 6 EXHIBIT 10.20 6.03 TITLE DEFECT: For the purpose of this Agreement, a "TITLE DEFECT" shall mean a material deficiency in one or more of the following respects: (a) Seller's title at the Effective Time, as to one or more of the Interests, is subject to an outstanding mortgage, deed of trust, lien or encumbrance, litigation, cause of action or other adverse claim not shown on Exhibit "D". Notwithstanding the above, unless such mortgage, deed of trust, lien or encumbrance is released prior to Closing, each of these matters shall be deemed a Title Defect; (b) Seller's net revenue interest in any of the properties is less than the net revenue interest which is set forth in Exhibit "B" for such property, or Seller's working interest in any of the properties is greater than the working interest shown in Exhibit "B" for such property without a corresponding increase in the net revenue interest for such property; (c) Seller is in default under some material provision of a lease, agreement or other contract affecting the Interests; or (d) Seller's rights and interests are subject to being reduced by virtue of the exercise by a third party of a reversionary, back-in or similar right not reflected or provided for in any of the agreements or other materials set forth in Exhibit "B". 6.04 NOTICE OF A TITLE DEFECT: Upon discovery of a Title Defect, Purchaser shall immediately notify Seller in writing of the nature of the Title Defect and furnish Seller Purchaser's basis for the assertion of such Title Defect and data in support thereof. Seller may request an increase in the Sale Price by delivery to Purchaser of written notice that the net revenue interest actually owned by Seller in any of the Interests is greater than that shown on Exhibit "B". Any Title Defect which is not disclosed to Seller within five (5) days prior to the Closing shall conclusively be deemed waived by Purchaser for all purposes. 6.05 REMEDIES FOR TITLE DEFECTS: Upon timely delivery of notice, either by Purchaser of a Title Defect or by Seller of an increase in net revenue interest, Purchaser and Seller shall meet and use their best efforts to agree on the validity of the claim and the amount of any required adjustments to the Sale Price, provided that in no event shall any Sale Price reduction for an affected property exceed the amount allocated to the affected property on Exhibit "B". If Purchaser and Seller cannot agree on the amount of such a Sale Price adjustment, said amount shall be determined in accordance with the following guidelines: (a) If the Title Defect is based upon Purchaser's notice that Seller owns a lesser net revenue interest, or the notice is from Seller to the effect that Seller owns a greater net revenue interest than that shown on Exhibit "B", then the portion of the Sale Price allocated on Exhibit "B" to the affected property shall be reduced or increased (as the 7 EXHIBIT 10.20 case may be) in the same proportion that the actual net revenue interest bears to the net revenue interest shown on Exhibit "B" for such property. (b) If the Title Defect is a lien, encumbrance or other charge upon a property which is liquidated in amount, then the adjustment shall be the sum necessary to be paid to the obligee to remove the Title Defect from the affected property. If the Title Defect represents an obligation or burden upon the affected property for which the economic detriment to Seller is not liquidated but can be estimated with reasonable certainty as agreed to by the parties, the adjustment shall be the sum necessary to compensate Purchaser at the Closing for the adverse economic effect which the Title Defect will have on the affected property. (c) Subject to Subsection 6.05(e), if the Title Defect cannot be accommodated pursuant to subsections 6.05(a) or 6.05(b) and the parties cannot otherwise agree on the amount of such an adjustment to the Sale Price or Seller cannot cure the Title Defect to the reasonable satisfaction of Purchaser prior to the Closing, the property affected by the Title Defect shall be excluded from the Interests conveyed to Purchaser at the Closing and the Sale Price shall be reduced by the amount allocated by Purchaser to the affected property on Exhibit "B". (d) Purchaser may only adjust the Sale Price for Title Defects at the Closing if the cumulative amount of such adjustments in its favor exceeds $100,000.00. Similarly, Seller may only adjust the Sale Price by reason of it owning a greater net revenue interest at the Closing if the cumulative amount of such adjustments in its favor exceeds $100,000.00. In the event the net amount of the Sale Price adjustments downward or upward pursuant to the foregoing exceeds five (5%) percent of the Sale Price, then Seller or Purchaser may, upon written notice to the other party, cancel this Agreement and the same shall be of no further force and effect, save and except that Seller shall return the Performance Deposit to Purchaser without interest. Litigation described in Exhibit "D" attached hereto shall not count towards the adjustments described in this subsection. (e) If Purchaser shall receive an adjustment at the Closing on account of a Title Defect, Seller shall have until a date that is ninety (90) days after the Closing Date to cure the Title Defect at its cost. If by such date, Seller can demonstrate to Purchaser's reasonable satisfaction the Title Defect has been cured, then Seller shall be entitled to reimbursement by Purchaser for the amount of the adjustment received by Purchaser at the Closing as a result of the Title Defect. If an assignment of such affected Interest was not made at Closing, Seller shall assign such affected Interest to Purchaser at such time as Purchaser remits the hereinabove amount to Seller. Purchaser shall pay such amount to Seller within ten (10) business days from the date that the parties agree the Title Defect has been cured. 24.17 CASUALTY DEFECT: If prior to the Closing any of the Interests are substantially damaged or 8 EXHIBIT 10.20 destroyed by fire or other casualty ("Casualty Defect"), Seller shall notify Purchaser promptly after Seller learns of such event. Seller shall have the right, but not the obligation, to cure the Casualty Defect by repairing such damage or, in the case of personal property or fixtures, replacing them with equivalent items no later than the Closing Date, all to Purchaser's reasonable satisfaction. If any uncured Casualty Defects exist at the Closing, Purchaser shall proceed to purchase the Interests affected thereby, and the Sale Price shall be reduced by the aggregate reduction in the value of the Interests on account of such Casualty Defects, as determined by the mutual agreement of the parties. If the parties fail for any reason to agree prior to the Closing on the amount of any Sale Price adjustments on account of Casualty Defects, Purchaser shall accept the affected Interests and the Sale Price shall be reduced by an amount determined by a mutually acceptable independent appraiser, equal to the value of all Casualty Defects not accounted for at the Closing. 6.07 MATERIAL CHANGE IN CONDITION: If Seller is unable to restore production (for a period of 20 consecutive days immediately prior to Closing and subsequent to the execution of this Agreement) from the Basal Massive reservoir in the Funk A-1 well to a rate no less than the average daily producing rate for the last complete month immediately preceding the re-completion of such well, then Purchaser and Seller shall negotiate in good faith to mutually adjust the Sale Price. If the Parties are unable to reach agreement, then Purchaser at its option may elect to (a) not accept an assignment of such Property and (b) not assume the related lawsuit set forth in Exhibit "D" and the Sale Price shall be reduced by the attributable allocated value on Exhibit "B". ARTICLE 7. THIRD PARTY RIGHTS AND CONSENTS It is understood by Purchaser that certain of the Interests are or may be subject to (1) preferential purchase rights, rights of first refusal and similar option rights in third parties to purchase a part of the Interests (collectively, "PREFERENTIAL RIGHTS") or (2) lessors' approvals or other consents to transfer any part of the Interests (other than governmental approvals and other consents routinely acquired after a transfer, including the non-transferability requirement of any license, permit, right-of-way, pipeline franchise or easement, or a requirement for renegotiation upon transfer of ownership) (collectively, "CONSENTS TO ASSIGN"). This Agreement shall be subject to the terms and conditions of such Preferential Rights and Consents to Assign. Seller shall use its best efforts to notify the holders of such Preferential Rights of the proposed transfer of the affected properties and the amount of the Sale Price allocated to such properties. If any third party exercises a valid Preferential Right, the affected properties shall be excluded from the Interests and the Sale Price reduced by the amount allocated to the affected properties. Seller shall promptly notify Purchaser of the exercise of any Preferential Right and of the lapse of any applicable period of time within which a Preferential Right must be exercised. Seller shall attempt to satisfy all Consent to Assign prior to the Closing Date. If a Consent to Assign is not obtained, then the affected properties shall be excluded from the Interests and the Sale Price reduced by (1) the amount 9 EXHIBIT 10.20 allocated to the affected properties, if the Consent to Assign prohibits the transfer of an oil and gas lease, interest in a unit, or other property, or (ii) in any other case, an amount mutually agreed to by Purchaser and Seller required to replace any material part of the Interests necessary for the continued production and sale of hydrocarbons from the Interests, or in the event the parties cannot agree to such amount, then the affected properties shall be excluded from the Interests and the Sale Price reduced by the amount allocated to the affected properties.
