Genesis has the legal right, power and authority to execute and deliver this Second Agreement, the Second Assignment and the other Second Master Documents and to perform all of its obligations hereunder and thereunder, including unanimous approval of the transactions by the audit committee of Genesis Energy, Inc., the general partner of Genesis, such audit committee consisting solely of independent directors (the "Audit Committee"). 6.2 The execution, delivery and performance by Genesis of this Second Agreement and the other Second Master Documents are within its powers and authority, have been duly authorized by all necessary board of director action on the part of Genesis Energy, Inc. (in its capacity as general partner of Genesis), and by the Audit Committee and do not and will not (i) violate any Governmental Requirement currently in effect having applicability to Genesis, other than violations which would not, individually or collectively, cause a Material Adverse Effect, or (ii) violate Genesis' limited partnership agreement or other governing documents, or (iii) result in a breach of or constitute a default (excluding breaches or defaults which, individually or collectively, would not have a Material Adverse Effect) under any indenture, bank loan, or credit agreement or farm-out agreement, program agreement or operating agreement, or any other agreement or instrument to which Genesis is a party or by which Genesis or its properties may be currently bound or affected. 6.3 Genesis is not in default under any Governmental Requirement, indenture, agreement, or instrument that would reasonably be expected to cause a Material Adverse Effect nor does any fact or condition exist at this time that would reasonably be expected to cause a Material Adverse Effect now or in the future under any Governmental Requirement, indenture, agreement or instrument; and all consents or approvals under such indentures, agreements, and instruments necessary to permit the valid execution, delivery, and performance by Genesis of the Second Master Documents have been obtained. 6.4 This Second Agreement and the other Second Master Documents have been duly executed and delivered by Genesis, and this Second Agreement and the Second Master Documents constitute the legal, valid, and binding acts and obligations of Genesis enforceable against Genesis in accordance with their terms, subject, however, to bankruptcy, insolvency, reorganization, and other laws affecting creditors' rights generally and general principles of equity. There are no bankruptcy, insolvency, reorganization, receivership or arrangement proceedings pending, being contemplated by or, to the knowledge of Genesis, threatened against Genesis. 6.5 All authorizations, consents, approvals, licenses, and exemptions of, and filings or registrations with, any Governmental Authority, that are required for the valid execution and delivery by Genesis of, or the performance by Genesis of its obligations under, this Second Agreement or the other Second Master Documents have been obtained or performed or the period for objection thereto expired, other than those which, if not obtained or performed, would not individually or collectively have a Material Adverse Effect; and no consent or vote of the limited partners of Genesis is required for the execution, delivery or performance by Genesis of this Second Agreement and the other Second Master Documents under Genesis' limited partnership agreement or other documents to which Genesis is a party. 6.6 There are no suits or proceedings pending or, to Genesis' knowledge, threatened against Genesis before any Governmental Authority, that if decided adversely to the interest of Genesis would reasonably be expected to have a Material Adverse Effect. 6.7 The Second Production Payment to be acquired by Genesis pursuant to this Second Agreement is being acquired for Genesis' own account and for investment and not for distribution in violation of applicable securities laws. ARTICLE VII PAYMENT TO DENBURY 7.1 As consideration for the sale of the Second Production Payment to Genesis and the assignment of the Assigned Contract Interests to Genesis by Denbury, Genesis shall pay to Denbury at the Second Closing, $4,800,000 in cash. ARTICLE VIII DISCLAIMER OF WARRANTIES 8.1 Denbury has allowed Genesis the opportunity to review the title to the Subject Interests, to satisfy itself as to all matters pertaining to the transactions contemplated by this Second Agreement, including but not limited to the sufficiency of CO2 reserves attributable to the Subject Interests to satisfy the CO2 delivery requirements under the Assigned Contract Interests, and to conduct other due diligence with respect to the Second Production Payment, the Subjects Interests, the Subject Lands, the Denbury Pipeline, the Applicable Plants, and the Additional Industrial Sale Contracts as Genesis deems necessary to consummate the transactions contemplated by this Second Agreement. 8.2 OTHER THAN THE EXPRESS REPRESENTATIONS AND WARRANTIES PROVIDED BY DENBURY HEREIN AND IN THE OTHER SECOND MASTER DOCUMENTS, DENBURY MAKES NO WARRANTIES AS TO (i) THE PRESENCE, QUALITY AND QUANTITY OF CO2 RESERVES ATTRIBUTABLE TO THE SUBJECT INTERESTS, (ii) THE AMOUNT, VALUE, QUALITY, QUANTITY, VOLUME OR DELIVERABILITY OF ANY CO2 OR CO2 RESERVES IN, UNDER OR ATTRIBUTABLE TO THE SUBJECT LANDS, (iii) THE GEOLOGICAL OR ENGINEERING CONDITION OF THE SUBJECT LANDS, (iv) THE ABILITY OF THE SUBJECT LANDS TO PRODUCE CO2, INCLUDING WITHOUT LIMITATION, PRODUCTION RATES, DECLINE RATES AND RECOMPLETION OPPORTUNITIES, (v) ANY PROJECTIONS AS TO EVENTS THAT COULD OR COULD NOT OCCUR, (vi) THE ACCURACY, COMPLETENESS, OR MATERIALITY OF ANY DATA, INFORMATION OR RECORDS FURNISHED TO GENESIS IN CONNECTION WITH THE SUBJECT INTERESTS, SUBJECT LANDS, THE DENBURY PIPELINE AND THE APPLICABLE PLANTS, INCLUDING INFORMATION CONTAINED IN ANY EXHIBIT of this Second Agreement, ANY SEISMIC DATA AND DENBURY's INTERPRETATION OR ANALYSIS of same, OR (vii) ANY OTHER MATTERS CONTAINED IN OR OMITTED FROM ANY INFORMATION OR MATERIAL FURNISHED TO GENESIS BY DENBURY. ANY DATA, INFORMATION OR OTHER RECORDS FURNISHED BY DENBURY ARE PROVIDED TO GENESIS AS A CONVENIENCE AND GENESIS' RELIANCE ON OR USE OF THE SAME IS AT GENESIS' SOLE RISK. ARTICLE IX INDEMNITY 9.1 Denbury hereby indemnifies Genesis and its successors and assigns and affiliates (each a "Genesis Indemnified Party") against, and agrees to defend and hold each Genesis Indemnified Party harmless from and against, any and all obligations, liabilities, claims, demands, suits, debts, accounts, liens or encumbrances, and all costs and expenses, including reasonable attorneys' fees relating thereto (collectively, "Claims"), that any Genesis Indemnified Party may suffer or incur and that result from (a) the ownership or operation of the Subject Interests, (b) the ownership of the Additional Industrial Sale Contracts prior to the Effective Date, (c) any inaccuracy of any representation or warranty of Denbury contained in this Second Agreement or in any other Second Master Document, (d) any breach of any covenant or agreement of Denbury contained in this Second Agreement or in any other Second Master Document, including but not limited to the covenants relating to the Retained Obligations; provided, however, that such indemnification shall not be construed to cover or include any of the matters identified in Section 8.2 (including but not limited to disclaimers of warranties relating to CO2 reserves or production) or any Claims to the extent, but only to the extent, such Claims are determined to be not payable because they fall within the scope of the force majeure provisions contained in the Second Master Documents or the Additional Industrial Sale Contracts. 9.2 Genesis hereby indemnifies Denbury and its successors and assigns and Affiliates (each a "Denbury Indemnified Party") against, and agrees to defend and hold each Denbury Indemnified Party harmless from and against, any and all Claims that each Denbury Indemnified Party may suffer or incur and that result from (a) except to the extent of any Claims arising solely as a result of Denbury's execution of the Second Assignment, the ownership or operation of the Second Production Payment, (b) except to the extent of any Claims arising as a result of Denbury's failure to comply with the Retained Obligations, the ownership of the Additional Industrial Sale Contracts after the Effective Date, (c) any inaccuracy of any representation or warranty of Genesis contained in this Second Agreement or any other Second Master Document, or (d) any breach of any covenant or agreement of Genesis contained in this Second Agreement or any other Second Master Document; provided, however, that such indemnification shall not be construed to cover or include any Claims to the extent, but only to the extent, such Claims are determined to be not payable because they fall within the scope of the force majeure provisions contained in the Second Master Documents or the Additional Industrial Sale Contracts. 9.3 No person entitled to indemnification hereunder or otherwise to damages in connection with or with respect to the transactions contemplated in the Agreement and the other Second Master Documents shall settle, compromise or take any other action with respect to any Claim that could prejudice or otherwise adversely impact the ability of the person providing such indemnification or potentially liable for such damages to defend or otherwise settle or compromise with respect to such Claim. 9.4 Each Party entitled to indemnification hereunder or otherwise to damages in connection with the transactions contemplated in Agreement or the other Second Master Documents shall take all reasonable steps to mitigate all losses, costs, expenses and damages after becoming aware of any event or circumstance that could reasonably be expected to give rise to any losses, costs, expenses and damages that are indemnifiable or recoverable hereunder or in connection herewith. 9.5 The indemnification provisions provided for in this Second Agreement shall be applicable whether or not the losses, costs, expenses and damages in question arose solely or in part from the gross, active, passive or concurrent negligence, strict liability or other fault of Genesis or Denbury, as applicable. The parties acknowledge that this statement complies with the express negligence rule and is conspicuous. ARTICLE X SECOND CLOSING 10.1 Unless the Parties otherwise agree in writing, the closing of the transactions contemplated by this Second Agreement (the "Second Closing") will occur on the date this Second Agreement is executed as first set forth above (the "Second Closing Date") 10.2 At the Second 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) Genesis shall deliver to Denbury the cash consideration described in Section 7.1 by wire transferring immediately available funds to the account of Denbury pursuant to wiring instructions furnished by Denbury to Genesis prior to the Second Closing Date; (b) The Parties shall execute, acknowledge and deliver the Second Assignment and the Second Contract Assignment; (c) The Parties shall execute and deliver the Second T&P Agreement; (d) Denbury shall obtain and deliver to Genesis multiple executed originals of the Second Agreement with Lenders executed by the holders of the Bank One Liens; (e) Denbury shall obtain and deliver to Genesis multiple executed originals of an acceptable release of liens with respect to the Bank One Liens encumbering the Subject Interests conveyed to Genesis pursuant to the Second Assignment; and (f) The Parties shall execute and deliver any other documents or instruments necessary or appropriate to effect or support the transactions contemplated in this Second Agreement, including but not limited to any amendments or other modifications of the First Master Documents that may be necessary or appropriate due to the execution and delivery of the Second Master Documents. 10.3 Promptly following the Second Closing, Genesis will cause counterparts of the Second Assignment, a mutually agreeable Memorandum of Second T&P Agreement, Second Agreement with Lenders and financing statements to be filed for record in all appropriate records in appropriate filing locations. Genesis will pay for all documentary, filing and recording fees required in connection with the filing and recording of the Second Master Documents. ARTICLE 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 Second 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 wells 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 Second 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 Additional 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 Second 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 Second 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 Second Production Payment) and it would not be economically practical, in Denbury's reasonable judgment (determined without regard to the burden of the Second 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 Second 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 Second Production Payment, insofar as it affects such pooled or unitized Subject Interests shall also be pooled and unitized, and in any such event such Second 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 Second 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 Second 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 Applicable Plants, (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 Second 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 Second 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 wells 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 Second Production Payment to the same extent that the Lost Interest was charged and burdened with the Second 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. The provisions of Section 11.11(b) and (c) of the First Purchase and Sale Agreement (along with the definitions of all applicable defined terms) are hereby incorporated herein by reference for all purposes as if stated herein in full. 11.12 Denbury acknowledges that, pursuant to this Second Agreement and the Second Contract Assignment, Genesis is acquiring all of Denbury's rights, interest and obligations in the Additional Industrial Sale Contracts. Notwithstanding such acquisition, there are certain covenants and obligations under the Additional Industrial Sale Contracts that must be satisfied by the owner or operator of the Subject Interests. Accordingly, Denbury covenants that, until the termination of the Additional Industrial Sale Contracts and subject to the applicable force majeure provisions in the Additional Industrial Sale Contracts, Denbury will fully and timely perform each and every covenant and agreement in the Additional Industrial Sale Contracts which must be performed by the Seller (as defined in the Additional Industrial Sale Contracts) and which relates to the ownership and operations of Seller's Reserves, the production of carbon dioxide from Seller's Reserves, and/or the measurement, metering, testing and other transportation services related thereto, including but not limited to the obligations and covenants in Sections 3.1, 4.5, 5.2, 6.6, 7.2, 7.3, 7.4, and 8.1 of the BOC-Sandhill Contract and Sections 3.1, 3.2, 4.2, 4.5, 5.1(c), 5.3, 6.3, 6.6, 7.2, 7.3, 7.4, and 8.1 of the Magna Carta 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 Additional Industrial Sale Contracts), unless each Buyer has purchased from Genesis, pursuant to each of the Additional Industrial Sale Contracts, the Dedicated Contract Quantity applicable to such Additional Industrial Sale Contracts. 11.14 For so long as the Additional Industrial Sale Contracts are in force and effect, the Second Production Payment Gas delivered by Denbury to Genesis shall meet the minimum quality specifications set forth in the Additional Industrial Sale Contracts. ARTICLE XII EXCHANGE OF INFORMATION; AUDIT RIGHTS 12.1 After the Second Closing, (a) Denbury will keep Genesis advised of Denbury's activities in the fields encompassing the Subject Lands insofar as such activities relate to the terms and provisions of this Second Agreement, (b) each Party shall promptly give, or cause to be given to the other Party, written notice of any event or circumstance, including, but not limited to every adverse claim or demand made by any Person or any Governmental Authority, that could reasonably be expected to have a Material Adverse Effect, (c) each Party shall give or cause to be given to the other Party written notice of every default under the Additional Industrial Sale Contracts and every adverse claim or demand made by any Person or any Governmental Authority related to the Additional Industrial Sale Contracts, promptly upon obtaining knowledge of such default, claim or demand and shall include in such notice a description in reasonable detail of the default, claim or demand and if such Party obtained knowledge of such default, claim or demand as a result of the receipt of a written notice, a copy of such written notice, and (d) each Party shall also provide information to the other Party as needed to confirm compliance with each Party's obligations under this Second Agreement and the other Second Master Documents, to keep the other Party updated as to matters relating to this Second Agreement and the other Second Master Documents, from time to time, and in response to reasonable inquiries by the other Party. 12.2 After the Second 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 Second Production Payment, the Additional Industrial Sale Contracts, and compliance with this Second Agreement and the other Second Master Documents.
