2.3 Genesis shall look solely to the receipt of Production Payment Gas as provided herein for satisfaction and discharge of the Production Payment, and Genesis shall not have any other recourse against Denbury for the payment and discharge of the Production Payment. However, the foregoing provision shall not relieve Denbury of any obligation to respond in damages for any breach of any of the covenants, agreements and obligations of Denbury hereunder or under any other Master Document.

2.5 In the event of any express conflict between the terms and provisions of this Agreement and the terms and provisions of the Assignment, the terms and provisions of the Assignment shall control. The inclusion in this Agreement of provisions not addressed in the Assignment shall not be deemed a conflict, and all such additional provisions contained herein shall be given full force and effect.

III.

PROCESSING AND TRANSPORTATION OF PRODUCTION PAYMENT GAS

3.1 After Closing, Denbury agrees to transport Production Payment Gas from the Receipt Points, and redeliver Production Payment Gas at the Delivery Points, in accordance with the provisions of the T&P Agreement. All Production Payment Gas shall be delivered by Denbury to the Delivery Points in compliance with the requirements set out in the T&P Agreement with respect to pressure, quantity and quality specifications. Under the T&P Agreement, Genesis will pay Denbury a Transportation Fee (as adjusted in accordance with the terms of the T&P Agreement), which initially shall be $0.16 per MCF, for transportation of the Production Payment Gas from the Receipt Points, processing of the Production Payment Gas through the ▇▇▇▇▇▇▇ Dome Plant, and redelivery of the Production Payment Gas to or on behalf of Genesis at the Delivery Points.

3.2 The processing and transportation of Production Payment Gas by Denbury as described in this Article shall be subject to the terms and provisions contained in this Article, as such terms and provisions may be further described or supplemented by the T&P Agreement. In the event of any conflict between the terms and provisions of this Article and the terms and provisions of the T&P Agreement, the terms and provisions of the T&P Agreement shall control. The inclusion in this Agreement of provisions not addressed in the T&P Agreement shall not be deemed a conflict, and all such additional provisions contained herein shall be given full force and effect.

IV.

ASSIGNMENT OF INDUSTRIAL SALE CONTRACTS

4.1 At Closing, Denbury will assign to Genesis all of its rights and interests in and to the Industrial Sale Contracts (the “Assigned Contract Interests”), subject to the terms and conditions contained in the Industrial Sale Contracts. The Assigned Contract Interests will be assigned by Denbury to Genesis pursuant to the Contracts Assignment. Notwithstanding such assignment, Denbury shall be obligated to continue to comply with the Retained Obligations.

4.2 At Closing, Genesis will assume the cost and responsibilities of administering the Assigned Contract Interests with respect to rights and obligations arising after the Effective Date and will report the sales and values of such sales to Denbury on a Monthly basis on or before the 10th day of each succeeding Month, in a manner and format agreed upon between the Parties, in order that Denbury can timely pay royalties attributable to the Production Payment Gas sold pursuant to the Industrial Sale Contracts. Notwithstanding anything herein to the contrary, without the prior written consent of Denbury, Genesis shall not amend or otherwise modify any terms or provisions of any of the Industrial Sale Contracts if such amendment or modification of the Industrial Sale Contracts shall in any manner whatsoever, directly or indirectly, modify the Retained Obligations or otherwise increase any obligations of Denbury under any of the Master Documents, including but not limited to any increase of the sales and delivery requirements under the Industrial Sale Contracts. If Denbury elects not to consent to any proposed amendment, Denbury shall provide a written explanation setting out the reasons for such election.

4.3 In the event of any conflict between the terms and provisions contained in this Article and the terms and provisions of the Contracts Assignment, the terms and provisions contained in the Contracts Assignment shall control. The inclusion in this Agreement of provisions not addressed in the Assignment shall not be deemed a conflict, and all such additional provisions contained herein shall be given full force and effect.

4.4 If at any time or from time to time during the Term Genesis determines that 167.5 million MCF is not sufficient to satisfy the sales and delivery requirements of the Industrial Sale Contracts (a “Deficiency”), Genesis shall promptly furnish Denbury with written notice of such determination, and such notice shall contain sufficient detail that is reasonably calculated to enable Denbury to determine the basis for Genesis’ determination of such Deficiency. If, after receipt of such notice, Denbury agrees with Genesis’ assessment of a Deficiency, Denbury agrees to amend the Production Payment to include such additional volumes of CO2 that are necessary to enable Genesis to satisfy the sales and delivery requirements of the Industrial Sale Contracts. If Denbury fails to agree with Genesis’ assessment of a Deficiency, then such matter shall be resolved pursuant to Article XIV. The agreed-upon amount of additional volumes necessary to enable Genesis to satisfy the sales and delivery requirements of the Industrial Sale Contracts (the “Additional Volumes”) shall be sold by Denbury to Genesis on the same terms and conditions, mutatis mutandis, as applicable to the Production Payment by virtue of this Agreement, and the value of, and consequently the consideration to be paid by Genesis to Denbury for, the Additional Volumes shall be calculated based on estimated cash flow from the Additional Volumes discounted to present net value using a fifteen percent (15%) per annum discount rate. Notwithstanding the foregoing, if it is determined that the Deficiency has occurred, in whole or in part, as a result of the sale by Genesis of Excess Volumes, Denbury shall not be obligated to deliver those Additional Volumes which are attributable to the sale of Excess Volumes by Genesis.

XI.

COVENANTS AND AGREEMENTS OF DENBURY

During the Term, and unless Genesis otherwise agrees in writing, Denbury covenants as follows, and agrees and undertakes, to perform each and all of the following covenants at Denbury’s sole and entire cost and expense:

11.1 Denbury will (without regard to the burden of the Production Payment) conduct and carry on the development, maintenance and operation of the Subject Interests with reasonable and prudent business judgment and in accordance with good oil and gas field practices and all applicable Governmental Requirements, and will drill such ▇▇▇▇▇ as a reasonably prudent operator would drill from time to time in order to develop the Subject Interests and to protect them from drainage. Nothing contained in this Section, however, shall be deemed to prevent or restrict Denbury from electing not to participate in any operation that is to be conducted under the terms of any operating agreement, unit operating agreement, contract for development or similar instrument affecting or pertaining to the Subject Interests (or any portion thereof) and allowing consenting parties to conduct nonconsent operations thereon, if such election is made by Denbury in good faith and in conformity with sound field practices. After the date of this Agreement, Denbury shall not enter into any transaction(s) or agree to any arrangements which, after taking into account then current required third party sales (including sales under the Industrial Sale Contracts) and Denbury’s and its affiliates’ usage, would result or be reasonably anticipated to result in an inability of Denbury to deliver the Scheduled Delivery Volumes to Genesis.

11.2 Denbury shall not voluntarily abandon any well heretofore or hereafter completed for production of CO2 on any of the Subject Lands or surrender, abandon or release any Subject Interest or any part thereof; provided however, that nothing in this Agreement shall obligate Denbury to continue to operate any well or to operate or maintain in force or attempt to maintain in force any Lease when, in Denbury’s reasonable opinion, exercised in good faith and as would a prudent operator not burdened by the Production Payment, such well or Lease ceases to produce or is not capable of producing in paying quantities (without regard to the burden of the Production Payment) and it would not be economically practical, in Denbury’s reasonable judgment (determined without regard to the burden of the Production Payment), to restore the productivity of such well by reworking, reconditioning, deepening, or plugging back such well. The expiration of a Lease in accordance with its terms and conditions shall not be considered to be a voluntary surrender or abandonment of such lease.

11.3 With respect to all oil, gas and mineral leases included in the Subject Interests, Denbury will in all material respects comply with, or cause to be complied with, all pertinent Governmental Requirements that from time to time are promulgated to regulate the production and sale or production or sale of CO2.

11.4 Certain of the Subject Interests may have been heretofore pooled and unitized for the production of CO2. Such Subject Interests are and shall be subject to the terms and provisions of such pooling and unitization agreements, and the Production Payment shall apply to and affect only that portion of the production from such units that accrues to such Subject Interests as burdened, encumbered or otherwise affected by any and all applicable pooling and unitization agreements. Denbury shall have the right and power to pool and unitize any of the Subject Interests and to alter, change or amend or terminate any pooling or unitization agreements heretofore or hereafter entered into, as to all or any part of the Subject Lands, upon such terms and provisions as Denbury shall in its sole discretion determine. If and whenever through the exercise of such right and power, or pursuant to any Governmental Requirement hereafter enacted, any of the Subject Interests are pooled or unitized in any manner, the Production Payment, insofar as it affects such pooled or unitized Subject Interests shall also be pooled and unitized, and in any such event such Production Payment shall apply to and affect only the production that accrues to such Subject Interests, as burdened, encumbered or otherwise affected by such pooling and unitization.

11.5 Denbury shall pay, or cause to be paid, before delinquent, all Taxes, except Taxes being contested in good faith. In the event that after the expiration of the Term, additional Taxes should be charged against Genesis which are attributable to Production Payment Gas produced during the Term and delivered to Genesis at the Receipt Point(s), Denbury shall be obligated to pay such Taxes.

11.6 Subject to the provisions of Section 2.4 hereof and Section 2.8 of the T&P Agreement, Denbury will at all times maintain, preserve and keep all Personal Property, the in good repair, working order and condition in all material respects, and promptly make all necessary and proper repairs, renewals, replacements and substitutions, to the end that the value of such Personal Property, shall in all material respects be fully preserved and kept in such condition as at all times to permit the most efficient and economical use and operation thereof.

11.7 Denbury will (i) use all commercially reasonable efforts to promptly pay, or cause to be paid, as and when due and payable all material rentals and royalties payable in respect of the Subject Interests or the production therefrom, and all material costs, expenses and liabilities for labor and material to the extent that the same are attributable to the Subject Interests, the Personal Property, the Denbury Pipeline or the ▇▇▇▇▇▇▇ Dome Plant, (ii) never permit any lien (other than Permitted Liens) to be affixed or burden the Subject Interests or Personal Property, even though inferior to the Production Payment, for any such bills which may be legally due and payable (other than Permitted Liens or liens which, individually or collectively, could not have a Material Adverse Effect), and (iii) never permit to be created or to exist in respect to any of the Subject Interests or the Personal Property, any other or additional lien on a parity with or superior to the Production Payment, except for Permitted Liens or other than liens which, individually or collectively, could not have a Material Adverse Effect.

11.8 Denbury shall not resign as operator of any Subject Interest operated by Denbury until and unless the successor operator has been approved in writing by Genesis, such approval not to be unreasonably withheld or delayed.

11.9 Denbury agrees to furnish Genesis, upon request, with copies of all electrical logs, core analyses, and completion reports relating to any well now or hereafter drilled upon the Subject Lands. Denbury agrees to furnish Genesis, upon request, with full information regarding the condition of the ▇▇▇▇▇ and the lease operations relating to the Subject Interests. The reasonable cost of copying any data and information described in this Section shall be paid by Genesis. Furthermore, Denbury’s disclosure of the data and information described in this Section is subject to and may be limited by any confidentiality obligations or other restrictions to which Denbury may be subject.

11.10 In the event that any Lease or other interest that constitutes a part of the Subject Interests should expire or terminate for any reason (a “Lost Interest”), and within one (1) year from date of such expiration or termination of such Lost Interest, Denbury should reacquire such Lost Interest, then such Lost Interest shall be charged and burdened with the Production Payment to the same extent that the Lost Interest was charged and burdened with the Production Payment, and Denbury agrees to execute such documents and agreements as may be necessary or appropriate to effect the intent and purpose of this section.

11.11 Airgas Obligations.

(a)

Section 4.2 of the Airgas Contract provides that Airgas at no time will pay a price for CO2 delivered under the terms of the Airgas Contract that is greater than the lowest price paid by any other customer of the Seller (as defined therein) or its affiliates receiving CO2 from the Source Field (as such terms are defined in the Airgas Contract). Section 4.2 of the Airgas Contract is hereafter referred to as the “Favored Nations Clause.” If at any time during the Term Denbury triggers the Favored Nations Clause, then Denbury agrees to (i) immediately notify Genesis of such sales and (ii) reimburse Genesis for the incremental reduction of proceeds received by Genesis under the Airgas Contract resulting from the payment of a reduced price by Airgas. If at any time and from time to time Airgas notifies Genesis that it is entitled to a lower price pursuant to the Favored Nations Clause (a “Reduced Price Notice”), Genesis will immediately furnish the Reduced Price Notice to Denbury. Genesis agrees not to take any action with respect to the Reduced Price Notice until Denbury has had an opportunity to review the matter described in the Reduced Price Notice and, if it deems appropriate, to contest such matter.

(b)

Section 11.4 of the Airgas Contract (the “RFR Provision”) provides that Airgas shall have the right to exercise its rights under the Right of First Refusal and Option to Purchase Agreement (as defined therein) upon the occurrence of certain events. Each Party agrees to notify the other Party if it receives the notice provided in the RFR Provision or if it becomes aware that Airgas has failed to receive 75% of its daily requirements of CO2 on more than 45 days in any rolling 12-month period (an “RFR Delivery Failure”). If Genesis is the cause of the RFR Delivery Failure (for reasons other than force majeure (as defined in the Airgas Contract)), then for so long as Genesis allows such RFR Delivery Failure to continue, Denbury shall have the right to make direct deliveries to Airgas in satisfaction of the delivery requirements in the Airgas Contract and all volumes delivered by Denbury pursuant to this sentence shall reduce the Scheduled Delivery Volumes otherwise deliverable pursuant to the Production Payment and, furthermore, for purposes of the Term, the total aggregate volumes included in the Term shall be reduced by an amount equal to 200% of the volumes so delivered pursuant to this sentence. If Denbury is the cause of the RFR Delivery Failure (for reasons other than (i) force majeure (as defined in the Airgas Contract) or (ii) a lack of reserves or insufficient deliverability of reserves (provided such lack of reserves or insufficient deliverability of reserves is not the result of a failure of Denbury to comply with covenants set out in Article XI)), and Airgas exercises its purchase rights in accordance with the RFR Provision, then, in addition to any other remedies that may be available, the Parties shall use good faith efforts to reach an agreement with respect to the allocation of proceeds paid by Airgas and their application to the Production Payment after it exercises its rights under the RFR Provision, and if the Parties are unable to reach such agreement, then such matter shall be resolved in accordance with the arbitration provisions contained in Article XIV.

(c)

Notwithstanding anything herein to the contrary, without the prior written consent of the other Party hereto, no Party shall amend or otherwise modify any terms or provisions of the Right of First Refusal and Option to Purchase Agreement.

11.12 Denbury acknowledges that, pursuant to this Agreement and the Contracts Assignment, Genesis is acquiring all of Denbury’s rights, interest and obligations in the Industrial Sale Contracts. Notwithstanding such acquisition, there are certain covenants and obligations under the Industrial Sale Contracts that must be satisfied by the owner or operator of the Subject Interests. Accordingly, Denbury covenants that, until the termination of each such Industrial Sale Contract and subject to the applicable force majeure provisions in the applicable Industrial Sale Contracts, it will fully and timely perform each and every covenant and agreement in each Industrial Sale Contract which must be performed by the Seller (as defined in each Industrial Sale Contract) and which relates to the ownership and operations of each Source Field, the production of carbon dioxide from each Source Field, and/or the measurement, metering, testing and other transportation services related thereto, including but not limited to the obligations and covenants in (a) Sections 2.5, 3.3, 5.3, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 7.1, 7.2, 7.3, 7.4, 8.1, 8.2 and 9.2 of the Airgas Contract; (b) Sections 2.5, 5.3, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 7.1, 7.2, 7.3, 7.4, 8.1 and 8.2 of the BOC-▇▇▇▇▇▇▇ Contract; and (c) Sections 2.5, 5.3, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 7.1, 7.2, 7.3, 7.4, 8.1 and 8.2 of the Praxair Contract. The covenants and agreements of Denbury described in this section are collectively referred to herein as the “Retained Obligations”.

11.13 Denbury shall not sell CO2 to any Buyer (as such term is defined in each of the Industrial Sale Contracts), unless each Buyer has purchased from Genesis, pursuant to each of the Industrial Sale Contracts, the total Daily Contract Quantity and Additional Volumes (as such terms are defined in each of the Industrial Sale Contracts) under each Industrial Sale Contract; provided, however, that notwithstanding the foregoing, Denbury shall be permitted to sell CO2 to any such Buyers pursuant to and in accordance with the terms of the following contracts (and any amendments, replacements or renewals thereof that perpetuate only the rights and obligations currently existing under such contracts): (i) Contract for Sale of Carbon Dioxide Gas dated November ___, 1995 (presumed to be effective February 1, 1996), by and between Pennzoil Exploration and Production Company, as Seller, and Pisgah Partners, L.P., as Buyer; (ii) Contract for Sale of Carbon Dioxide Gas dated December 18, 2000, by and between Magna Carta Group LLC, as Seller, and ▇▇▇▇▇▇ Greisheim Industries, Inc., as Buyer; and (iii) Carbon Dioxide Sale and Purchase Contract dated and effective February 1, 1996, by and between Shell Western E&P Inc., as Seller, and Liquid Carbonic Industries Corporation, as Buyer, as amended by Amendment No. 1 dated as of December 1, 1996, between Seller and Buyer.

11.14 For so long as the Industrial Sale Contracts are in force and effect, the Production Payment Gas delivered by Denbury to Genesis shall meet the minimum quality specification set forth in the Industrial Sale Contracts.

12.2 After Closing, each Party, by notice in writing to the other Party, shall have the right to audit the other Party’s accounts and records relating to the Production Payment, the Industrial Sale Contracts, and compliance with this Agreement and the other Master Documents. Audit rights pertaining to the T&P Agreement are subject to the terms and provisions with respect to auditing as set forth in the T&P Agreement. Audit rights otherwise pertaining to the Production Payment, the Industrial Sale Contracts, or other compliance issues under this Agreement and the other Master Documents are subject to the terms of Section 12.3.

12.3 Audits shall not be conducted more than twice each year without prior approval of the Party whose records are being audited (the “Audited Party”), and shall be made at the expense of the Party conducting the audit. The Audited Party shall reply in writing to an audit report within thirty (30) days after receipt of such report. The Parties will endeavor to agree upon and make any adjustments revealed to be necessary by any audit reports submitted by the Audited Party pursuant to the provisions of this Section.

CURTAILMENTS AND INTERRUPTIONS

15.1 If Denbury is unable on any day, whether due to interrupted or curtailed service at the ▇▇▇▇▇▇▇ Dome Plant, lack of deliverability from the producing ▇▇▇▇▇, or lack of capacity on the Denbury Pipeline, or any other reason, to transport all volumes of CO2 tendered for transportation through the Denbury Pipeline (inclusive of all volumes which Denbury may tender for transportation for its own account), and excluding those instances of inability to transport due to force majeure (in which cases the specific provisions as to force majeure in the Master Documents or in the relevant Industrial Sale Contracts will control), Denbury may interrupt or curtail service or receipt or delivery of CO2, without liability to or penalty payable to Genesis, in a manner (i) so that volumes attributable to the Airgas Contract (“Airgas Volumes”) are subject to curtailment only after complete curtailment of volumes attributable to all other parties, and then Airgas Volumes will be curtailed only as may be permitted under the Airgas Contract; (ii) so that the Excess Volumes and the volumes attributable to each of the BOC Contract and the Praxair Contract will be curtailed on a basis that is pro-rata to the volumes attributable to each of those contracts set forth in Schedule 5.18 and Denbury for its own account; provided that if the interruption or curtailment of service is longer than 45 consecutive days, then any volumes which Denbury tenders for transportation for its own account will not be included in the proration under clause (ii) above unless and until 100% of the Scheduled Delivery Volumes have been transported, determined in each case on a daily basis. In all circumstances above requiring curtailment, all pro-rations of volumes shall be proportionately based on the actual average volumes which have been transported during the 30 days before the interruption or curtailment of service occur.

XVI.

16.2 This Agreement may be amended, modified, and supplemented only by written instrument executed by both Parties and explicitly referred to as an amendment to this Agreement.

16.5 The interests of the Parties in this Agreement, and the interests acquired by virtue of this Agreement and the interests retained by Denbury in the Subject Lands, may not be subsequently assigned, either in whole or in part, unless (i) any such assignee expressly agrees in writing to assume and perform all of the assignor's obligations under this Agreement and the other Master Documents, and (ii) such assignment is made and accepted expressly subject and subordinate to this Agreement and the other Master Documents.
