If (i) either Seller or Guarantor grants liens or security interests on a substantial part of its or its Subsidiary's property or assets to secure its bank debt or bonds generally, (ii) a Change of Control occurs that results in Guarantor or its successor being rated less than Approved Investment Grade, or (iii) the unsecured long term debt of the Guarantor shall be rated below Investment Grade at any time, then Seller shall deliver to Buyer within five business days after the Royalty Owner's request therefor an acceptable irrevocable letter of credit in a face amount of $20,000,000 issued by an issuer with credit ratings of its senior unsecured long term Indebtedness of A+ (or higher) by S&P and A2 (or higher) by Moody's Investors Service or, alternatively A (or higher) by S&P and A1 (or higher) by Moody's Investors Service and (except to the extent such letter of credit is drawn upon) Working Interest Owner shall maintain such letter of credit, or one or more replacement letters of credit meeting such criteria, in effect for the benefit of Royalty Owner until such time as Guarantor or its successor is once again rated Investment Grade. Each such letter of credit shall have attached thereto a form of drawing certificate substantially in the form of Exhibit D hereto, with appropriate insertions, shall require no documents to be presented for drawing other than such certificate (and the letter of credit itself), and shall otherwise be in such issuing bank's standard form for "clean" irrevocable standby letters of credit. Royalty Owner may draw upon such letter of credit in any of the circumstances contemplated in Exhibit D, but only in such circumstances. If any such drawing is made in connection with a failure of performance or payment under the Pioneer Guaranty (or a replacement thereof), the funds drawn shall be used to provide a remedy to Royalty Owner for such failure. If any such drawing is made in connection with a notice of termination of such letter of credit, or a failure to provide a replacement letter of credit, the funds drawn shall be 12 held by Royalty Owner as cash collateral (a) until needed to provide a remedy to Royalty Owner for a failure of performance or payment under the Pioneer Guaranty (or a replacement thereof), or (b) until an acceptable replacement letter of credit is in fact provided to Royalty Owner, or (c) until Guarantor or its successor is once again rated Investment Grade. Upon the occurrence of either circumstance described in the preceding clauses (b) or (c), any remaining cash collateral shall be promptly returned to Guarantor or its successor. As used herein, "Change of Control" means (a) the acquisition of ownership, directly or indirectly, beneficially or of record, by any Person or group (within the meaning of the Securities Exchange Act of 1934 and the rules of the Securities and Exchange Commission thereunder as in effect on the date hereof), of equity interests representing more than 35% of the aggregate ordinary voting power represented by the issued and outstanding equity interests of the Guarantor; or (b) occupation of a majority of the seats (other than vacant seats) on the board of directors of the Guarantor by Persons who were neither (i) nominated by the board of directors of the Guarantor nor (ii) appointed by directors so nominated. For purposes hereof, a Person shall be deemed rated "Investment Grade" if the long-term senior unsecured obligations of such Person are rated at or above BBB- by S&P and Baa3 by Moody's. ARTICLE VI ADJUSTMENT OF SCHEDULED QUANTITIES SECTION 6.01. Additional Definitions As used in this Article VI, the following terms have the following meanings: "Adjustment Quantity" shall have the meaning given to such term in the Conveyance. "PDP Reserves" means proved developed producing reserves of Methane, as determined in accordance with the definitions and standards promulgated by the Society of Petroleum Engineers. Each calculation of PDP Reserves shall be based on the then most recent reserve engineering report provided under Section 4.4 of the Conveyance. "Remaining Reserves" means, as of the date of any determination, all of the PDP Reserves projected to be attributable to the Subject Interests (whether attributable to the Production Payment or to Working Interest Owner's retained interests) after such date for the remaining expected productive life thereof. "Tail Ratio" means the ratio of the Tail Reserves to the Remaining Reserves. "Tail Reserves" means, as of the date of any determination, the Remaining Reserves projected to be attributable to the Subject Interests after the Target Termination Time. "Target Termination Time" means January 1, 2010 (or, if any Adjustment Quantity is expected to exist at such time, after the first date thereafter on which no Adjustment Quantity is expected to exist). SECTION 6.02. Covenant to Amend Conveyance A. Option to Adjust Scheduled Quantities. 13 If for any reason at any time, or from time to time, both of the following conditions exist: (1) the Tail Ratio is less than fifty percent (50%), and (2) the production of Subject Hydrocarbons for any period of January 1 through June 30 or any period of July 1 through December 31 exceeds 120% of the projected production of Subject Hydrocarbons attributable to the Subject Wells for such period as set forth in the most recent Reserve Report, (assuming equal semi-annual production during each year for which such projected production is set forth only on a yearly basis), then Royalty Owner shall have the option to cause the remaining Scheduled Quantities to be adjusted as provided in Subsection B of this Section. B. Procedure to Adjust Scheduled Quantities. Upon Royalty Owner's election to exercise the option set forth in Subsection A of this section, Working Interest Owner shall in good faith adjust the Scheduled Quantities by preparing a revised Schedule 1 to the Conveyance that results, at the time of Royalty Owner's exercise of the option, in a Tail Ratio as of the Target Termination Time that is greater than, but as near as reasonably possible to fifty percent (50%); provided, however, that (i) Working Interest Owner shall not increase Scheduled Quantities in any Month to more than 95% of the Methane projected in the relevant Reserve Report to be produced and saved in such Month, (ii) Working Interest Owner shall consult with Royalty Owner about adjustments to Scheduled Quantities that will minimize costs under Subsection D below, and (iii) in no event shall any adjustments to the Scheduled Quantities extend the Termination Time or decrease Scheduled Quantities in any earlier Month if any later Month is increased or changed or if any Month has a smaller proportional decrease. In addition, any adjustment to the Scheduled Quantities under this Section shall result in a net present value of the adjusted Scheduled Quantities equal to the net present value of the Scheduled Quantities prior to such adjustment. The net present value of the Scheduled Quantities prior to such adjustment shall be equal to the net present value (before deduction of federal income taxes) of each Month's Scheduled Quantities as of the date of determination, assuming that such Scheduled Quantities will be sold at a price whose index component is the net fixed price to be paid under Royalty Owner's commodity and basis swaps as then in effect with respect to such Scheduled Quantity (in this Section, the "Related Commodity Swap") and discounting the assumed sales proceeds at a discount rate of 4.625%. The net present value of the adjusted Scheduled Quantities shall be equal to the net present value (before deduction of federal income taxes) of each Month's adjusted Scheduled Quantities as of the date of determination, assuming that the unchanged Scheduled Quantities will be sold at the prices provided for in the preceding sentence and any increased Scheduled Quantities for any month will be sold at a price then available under an achievable market swap whose index component is the net fixed price to be paid under Royalty Owner's commodity and basis swaps to be entered into with respect to such increased Scheduled Quantity (in this Section, the "Related Adjusted Commodity Swap") and discounting the assumed sales proceeds at a discount rate equal to the sum of an achievable one month LIBOR rate under a swap plus 87.5 basis points and taking into account the costs (less the benefits) to Royalty Owner of adjusting (both unwinding for reductions in Scheduled Quantities and adding or supplementing for increases in 14 Scheduled Quantities) the Related Adjusted Commodity Swap to reflect the change in the Scheduled Quantities and similarly adjusting the interest rate swaps of Royalty Owner. To the extent that, after doing the foregoing, any such net unwind costs still result in a present value of adjusted Scheduled Quantities that is less than the present value of the Scheduled Quantities prior to such adjustment, Working Interest Owner shall make further adjustments to Scheduled Quantities to eliminate such shortfall and, if necessary, to extend the Termination Time. Within 20 days of Royalty Owner's election, Working Interest Owner shall present the revised Schedule 1 to Royalty Owner for verification that the revised Schedule complies with the foregoing requirements. If Royalty Owner agrees with the revised Schedule 1, Working Interest Owner shall promptly prepare a supplement to the Conveyance incorporating the revised Schedule 1 into the Conveyance, Working Interest Owner and Royalty Owner shall promptly execute and acknowledge such supplement, and Working Interest Owner shall, at its expense, cause such amendment to be filed promptly in all appropriate county records. C. Determination by Petroleum Engineer. If Working Interest Owner and Royalty Owner do not agree upon Working Interest Owner's revised Schedule 1 and execute and acknowledge a supplement to the Conveyance pursuant to Subsection B above, then the Petroleum Engineer shall within 30 days determine the revisions to be made to Schedule 1 to achieve the result set out in the first sentence of Subsection B above. The fees and expenses of the Petroleum Engineer shall be borne equally by Working Interest Owner and Royalty Owner. The determination of the Petroleum Engineer shall be binding upon Working Interest Owner and Royalty Owner and, upon the determination by the Petroleum Engineer of the contents of the revised Schedule 1, Working Interest Owner shall promptly prepare a supplement to the Conveyance incorporating the revised Schedule 1 into the Conveyance, Working Interest Owner and Royalty Owner shall promptly execute and acknowledge such supplement, and Working Interest Owner shall, at its expense, cause such amendment to be filed promptly in all appropriate county records. D. Ancillary Costs. All costs and expenses resulting from any exercise of the option provided in Subsection B above shall, to the extent not included in the net present value calculation described in Subsection B above, be paid promptly by Working Interest Owner. Among such costs and expenses are (a) any costs and expenses of adjusting and unwinding the Production Sales Contracts to match or approximate the new Scheduled Quantities, and (b) if the Production Sales Contracts are not amended, any penalties, extra charges, or reductions in purchase price resulting from Scheduled Quantities that are more or less than the quantities of Hydrocarbons specified in the Production Sales Contracts. ARTICLE VII COVENANTS OF SELLER AND BUYER SECTION 7.01. Public Announcements. Section 8.10 of the Conveyance and Section 11.15 hereof set out the obligations of the parties hereto with respect to certain confidential information. The parties acknowledge and agree, however, that such obligations 15 shall not restrict Royalty Owner, Working Interest Owner or Guarantor from filing this Agreement or the Related Agreements with the Securities Exchange Commission or any other Governmental Authority or from describing this Agreement, the Related Agreements, or the transactions contemplated herein or therein in any press release or other public statement or any earnings or analyst conference calls. Section 8.10 of the Conveyance and Section 11.15 hereof shall not be deemed to prevent the filing and recording of the Conveyance or any mortgage, financing statement or similar agreement by any lender (or trustee or agent on any lender's behalf) to Buyer in the public deed records. Buyer's lenders and their Affiliates, including Wachovia Bank, National Association may also publish customary "tombstone" announcements in such publications as they deem appropriate following the Closing Date, and the parties hereto and their respective counsel may from time to time refer to such "tombstones" and repeat the content thereof to third parties. SECTION 7.02. Buyer's Mortgage. As provided in Section 7.1 of the Conveyance, Buyer may grant liens and security interests in, to and covering the Production Payment and also Buyer's rights under this Agreement. SECTION 7.03. Survival Past Closing. All of the representations, warranties, covenants and agreements contained in this Agreement shall survive the Closing and the delivery of the Conveyance and continue until the termination of the Production Payment as provided in the Conveyance. SECTION 7.04. Reasonable Cooperation. From and after the date hereof, the each Seller and their Affiliates shall reasonably cooperate with the Buyer and its counsel in connection with the offering and sale of loans, certificates of ownership interest, or other instruments secured by, payable from or representing ownership interests in the Production Payment (such instruments, "VPP Instruments"), provided, however, that such reasonable cooperation shall be at Buyer's expense and shall be limited to the following: (i) providing non-confidential information available to either Seller that the Buyer and/or its counsel deems reasonably necessary in connection with the offering and sale of VPP Instruments; and (ii) making available to Buyer's lenders, financiers and rating agencies, such officers and engineers as Buyer may reasonably request in order to assist Buyer in any financing or securitization. SECTION 7.05. Preferential Purchase Rights. If a third party properly and lawfully exercises a preferential right to purchase the Production Payment or a portion thereof after the Closing, then Buyer will reconvey the Production Payment or such portion thereof to Seller in order that Seller may make the necessary conveyance to such third party purchaser, and Seller and Buyer shall amend the Conveyance (including the "Scheduled Quantities" listed therein) accordingly. The consideration payable by such third party purchaser upon the exercise of such preferential right shall be paid over by Seller to Buyer in consideration of Buyer's reconveyance. Since the entire purchase price paid hereunder by Buyer consists of both the Cash Purchase Price and Buyer's assumption of certain hedging contracts with Wachovia Bank, 16 National Association pursuant to the Novation Agreement, Seller and Buyer shall together decide whether to request Wachovia Bank, National Association to permit such third party purchaser, as part of its purchase price, to assume a proportionate portion of the liabilities under such hedging contracts agreements or whether to calculate the value of such liabilities as a component of the cash purchase price to be paid by such third party purchaser. Seller will also indemnify and hold harmless Buyer for any losses and expenses suffered by Buyer as the result of the exercise of any such preferential right to purchase, to the extent not compensated by the payment to Buyer of the consideration paid by such third party purchaser.

Except as provided in Section 7.02 hereof, nothing in this Agreement is intended to confer upon any Person, other than the parties and their respective successors and permitted assigns, any rights, benefits, remedies or obligations hereunder; and no Person, other than the parties and their respective successors and permitted assigns, is entitled to rely on any representation, warranty, covenant, or agreement contained herein; provided, however, that, Buyer and its successors and permitted assigns shall be entitled to enforce the terms of Article X for the benefit of any Persons who are Indemnified Parties. Any claim for indemnification under Article X on behalf of an Indemnified Party other than Buyer (or Buyer's successor or permitted assign) must be made and administered by Buyer or its successors or permitted assign. For avoidance of doubt, permitted assigns of Buyer include Buyer's Affiliates and managed commercial paper conduits and Buyer's and such Affiliate's respective owners, investors, insurers, lenders, and any providers of any commodity or interest rate hedging products. 25 SECTION 11.13. Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any adverse manner to any party. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible. SECTION 11.14. No Retained Liens. No lien or encumbrance of whatsoever nature, express or implied, shall be retained by or created in favor of either Seller in or against the Production Payment as security for payment or performance of the Purchase Price or any other obligations of Buyer; and each Seller hereby expressly waives and releases any such express or implied liens and encumbrances. SECTION 11.15. Confidentiality. Each party hereto shall hold in confidence any confidential information it has obtained from another party hereto as provided in Section 8.10 of the Conveyance. SECTION 11.16. Limitations on Damages. NEITHER PARTY HERETO SHALL BE RESPONSIBLE TO THE OTHER PARTY OR TO ANY PERMITTED BENEFICIARY HEREOF FOR CONSEQUENTIAL DAMAGES OR PUNITIVE OR EXEMPLARY DAMAGES. SECTION 11.17. Tax Treatment. Although the Production Payment is a real property interest for purposes of state law, the parties agree to treat the Production Payment as a mortgage loan for federal income tax purposes. For avoidance of doubt, the parties acknowledge that Sellers (and not Buyer) are entitled to all tax credits (including credits under Section 29 of the Code) attributable to the Production Payment and the production attributable thereto. SECTION 11.18. No Recourse. EACH PARTY HERETO HEREBY AGREES THAT THE OBLIGATIONS AND LIABILITIES OF THE BUYER UNDER THIS AGREEMENT ARE SOLELY THE LIMITED LIABILITY COMPANY OBLIGATIONS AND LIABILITIES OF THE BUYER, AND NO OFFICER, DIRECTOR, MEMBER, MANAGER, EMPLOYEE, AGENT OR AFFILIATE OF THE BUYER SHALL HAVE ANY PERSONAL LIABILITY THEREFOR.
