As soon as reasonably practicable, but not later than the fifteen^th (15th) day following receipt of Seller’s statement hereunder, Purchaser may deliver to Seller a written report containing any changes that Purchaser proposes be made in such final settlement statement. Any changes not so specified in such written report shall be deemed waived and Seller’s determinations with respect to all such elements of the final settlement statement that are not addressed specifically in such report shall prevail. If Purchaser fails to timely deliver a written report to Seller containing changes Purchaser proposes to be made to the final settlement statement, the final settlement statement as delivered by Seller will be deemed to be correct and mutually agreed upon by the Parties, and, without limiting the application of Section 10.1(d), will be final and binding on the Parties and not subject to further audit or arbitration. Seller may deliver a written report to Purchaser during the same fifteen (15) day period reflecting any changes that Seller proposes to be made in such statement as a result of additional information received after the statement was prepared. The Parties shall undertake to agree on the final settlement statement of the Adjusted Purchase Price no later than thirty (30) days following Purchaser’s receipt of Seller’s statement delivered hereunder. In the event that the Parties cannot reach agreement as to the final settlement statement of the Adjusted Purchase Price within such period of time, any Party may refer the items of adjustment which are in dispute or the interpretation or effect of this Section 2.6 to a nationally recognized independent accounting firm or consulting firm mutually acceptable to both Purchaser and Seller (the “Accounting Referee”), for review and final determination by arbitration. The Accounting Referee shall conduct the arbitration proceedings in Houston, Texas in accordance with the Commercial Arbitration Rules of the AAA, to the extent such rules do not conflict with the terms of this Section 2.6(b). If the Parties are unable to mutually agree upon an Accounting Referee, then the Houston office of the AAA shall choose such Accounting Referee. The Accounting Referee, once appointed, shall have no ex parte communications with the Parties concerning the expert determination or the items of adjustment which are in dispute. All communications between any Party and the Accounting Referee shall be conducted in writing, with copies sent simultaneously to the other Party in the same manner, or at a meeting to which all Parties have been invited and of which such Parties have been provided at least five (5) Business Days’ notice. The Accounting Referee’s determination, based on materials submitted to the Accounting Referee as described above and not by independent review, shall be made within fifteen (15) days after submission of the matters in dispute and, without limiting the application of Section 10.1(c), shall be final and binding on all Parties, without right of appeal. In determining the amount of any adjustment to the Adjusted Purchase Price, the Accounting Referee shall be bound by the terms of this Agreement (including, Section 2.4 and Section 2.5) and shall be limited to selecting either Seller’s position or Purchaser’s position on each disputed amount. The Accounting Referee shall act as an expert for the limited purpose of determining the specific disputed aspects of the Adjusted Purchase Price adjustments submitted by any Party and may not award damages, interest (except to the extent expressly provided for in this Section 2.6) or penalties to any Party with respect to any matter. The non-prevailing Party shall pay all costs and expenses (including reasonable attorneys’ fees, the costs associated with each Party presenting its case and the costs and fees of the Accounting Referee). Within five (5) Business Days after the earlier of (i) the expiration of Purchaser’s fifteen (15) day review period without delivery of any written report and (ii) the date on which the Parties or the Accounting Referee finally determine the Adjusted Purchase Price, (A) Purchaser shall pay to Seller the amount by which (1) the Adjusted Purchase Price exceeds (2) the Closing Payment, plus the Deposit, plus the Holdback Amount or (B) Seller shall pay to Purchaser the amount by which (1) the Closing Payment plus the Deposit, plus the Holdback Amount exceeds (2) the Adjusted Purchase Price, as applicable (and in either case, without regard to any Defect Escrow Amounts).

-32-

(c)Purchaser shall reasonably assist Seller in preparation of the final settlement statement of the Adjusted Purchase Price under Section 2.6(b) by furnishing invoices, receipts, reasonable access to personnel and such other assistance as may be reasonably requested by Seller (and in Purchaser’s possession) to facilitate such process post-Closing.

(d)All payments made or to be made under this Agreement to Seller shall be made by electronic transfer of immediately available funds to such bank and account as may be specified by Seller in writing. All payments made or to be made hereunder to Purchaser shall be by electronic transfer of immediately available funds to such bank and account as may be specified by Purchaser in writing.

Section 2.7 Costs and Revenues.

(a)With respect to revenues earned or Property Costs incurred with respect to the Assets prior to the Effective Time but received or paid after the Effective Time:

(i)Except for amounts for which the Unadjusted Purchase Price was adjusted under Section 2.4(g)(iii) or otherwise included in the Assets, Seller shall be entitled to all amounts earned from the sale of Hydrocarbons (x) produced from, or attributable to, the Oil and Gas Properties prior to the Effective Time, which amounts are received prior to, on, or after Closing, and to all other income earned with respect to the Assets up to but excluding the Effective Time and received prior to, on or after Closing until the Cut-Off Date, (y) to the extent attributable to the Estimated Revenue Amounts to the extent that the same resulted in a downward adjustment to the Unadjusted Purchase Price or (z) to the extent attributable to any Recouped Amounts.

(ii)Seller shall be responsible for (and entitled to any refunds and indemnities with respect to) all Property Costs with respect to Seller’s interests in the Assets incurred prior to the Effective Time; provided, however, that Seller’s responsibility for the foregoing shall terminate on the Cut-Off Date.

(iii)Except amounts for which the Unadjusted Purchase Price was adjusted under Section 2.4(g)(i), for the Estimated Revenue Amounts to the extent that the same resulted in a downward adjustment to the Unadjusted Purchase Price or for any Recouped Amounts, Purchaser shall be entitled to all Hydrocarbons produced from, or attributable to, the Oil and Gas Properties from and after the Effective Time.

(iv)Purchaser shall pay and be responsible for (and entitled to any refunds and indemnities with respect to) (A) all Property Costs incurred from and after the Effective Time, and (B) all costs described in Section 2.7(a)(ii) once Seller’s responsibility for the same terminates on the Cut-Off Date.

-33-

(b) Without duplication of any adjustments made pursuant to Section 2.4(h), (i) should Purchaser or any Affiliate of Purchaser receive after Closing but before the Cut-Off Date any proceeds or other income to which Seller is entitled under Section 2.7(a), Purchaser shall fully disclose, account for, and promptly remit the same to Seller and (ii) should Seller or any Affiliate of Seller receive after Closing any proceeds or other income to which Purchaser is entitled under Section 2.7(a), Seller shall fully disclose, account for, and promptly remit the same to Purchaser.

(c)Without duplication of any adjustments made pursuant to Section 2.4(h), (i) should Purchaser, or any Affiliate of Purchaser, pay after Closing but before the Cut-Off Date any Property Costs for which Seller is responsible under Section 2.7(a), Purchaser shall be reimbursed by Seller promptly after Seller’s receipt of Purchaser’s invoice, accompanied by copies of the relevant vendor or other invoice and proof of payment and (ii) should Seller, or any Affiliate of Seller, pay after Closing any Property Costs for which Purchaser is responsible under Section 2.7(a), Seller shall be reimbursed by Purchaser promptly after Purchaser’s receipt of Seller’s invoice, accompanied by copies of the relevant vendor or other invoice and proof of payment.

(d)As part of the Accounting Services, and without duplication of any amounts that were previously accounted for in the Preliminary Settlement Statement or limitation of the general allocation of revenues and Property Costs set forth in this Section 2.7, Seller shall submit any joint interest billings or other invoices for Property Costs to Purchaser, and shall remit to Purchaser its share of revenues, in each case, attributable to the Assets for the production month of December 2023, in the ordinary course of business consistent with past practices, and concurrently with remittances to other Third Parties. For the avoidance of doubt, the Parties hereby agree that this Section 2.7(d) shall govern the submission and remittance of those items expressly described herein, and the final settlement statement contemplated in Section 2.6(b) shall not include any amounts that are otherwise resolved pursuant to this Section 2.7(d).

(e)Seller shall have no further responsibility for Property Costs incurred with respect to the Assets for which Seller otherwise would be responsible under Section 2.7(a), to the extent such amounts have not been paid on or before the Cut-Off Date.

(f) For the avoidance of doubt and notwithstanding anything to the contrary in this Agreement, the Purchase Price adjustment contemplated and set forth in Section 2.4(h)(iv) shall only be taken into account in the final settlement statement contemplated in Section 2.6(b) and shall not be made in the Preliminary Settlement Statement. Furthermore, the adjustment to be made pursuant to Section 2.4(h)(iv) in the final settlement statement shall be limited to those amounts that (i) are set forth on Schedule 2.4(h)(iv) and (ii) have been recouped for the benefit of Purchaser for the production months that occurred from and after the Effective Time through the December 2023 production month. In the event any amounts set forth on Schedule 2.4(h)(iv) are recouped by Purchaser (or for the benefit of Purchaser) during any production month following the December 2023 production month (such amounts being referred to herein as the “Recouped Amounts”), Purchaser hereby agrees that Seller shall be entitled to any such amounts and Purchaser agrees to turn over the same to Seller pursuant to Section 2.7(b).

-34-

Section 2.8 Allocation of Purchase Price. Purchaser and Seller shall use commercially reasonable efforts to agree to an allocation of the Adjusted Purchase Price and any other items properly treated as consideration for U.S. federal income Tax purposes among the six categories of assets specified in Part II of IRS Form 8594 (Asset Acquisition Statement under Section 1060), in accordance with Section 1060 of the Code and the Treasury Regulations promulgated thereunder and, to the extent allowed under applicable federal income Tax Law, in a manner consistent with the Allocated Values, within thirty (30) days after the determination of the final settlement statement (the “Allocation”). If Seller and Purchaser reach an agreement with respect to the Allocation, (a) Purchaser and Seller shall use commercially reasonable efforts to update the Allocation in accordance with Section 1060 of the Code following any adjustment to the purchase consideration for Tax purposes pursuant to this Agreement, and (b) Purchaser and Seller shall, and shall cause their respective Affiliates to, report consistently with the Allocation, as adjusted, on IRS Form 8594 (Asset Acquisition Statement under Section 1060), which Purchaser and Seller shall timely file with the IRS, unless otherwise required by applicable Law; provided, however, that (A) if Seller and Purchaser cannot mutually agree on the Allocation, each Party shall be entitled to determine its own allocation and file its IRS Form 8594 consistent therewith and (B) neither Party shall be unreasonably impeded in its ability and discretion to negotiate, compromise and/or settle any Tax audit, claim or similar proceedings in connection with such Allocation.

Section 2.9 Withholding. Purchaser shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as are required to be deducted and withheld under any applicable provision of Tax Law; provided, however, that, except with respect to any withholding required as a result of any Seller Entity failing to provide an IRS Form W-9 to Purchaser as contemplated by Section 9.2(d), Purchaser shall use commercially reasonable efforts to provide Seller with written notice of its intent to withhold reasonably in advance of such deduction or withholding, along with a description of the legal basis therefor, and shall cooperate in good faith with Seller to mitigate, reduce, or eliminate any such deduction or withholding. To the extent that amounts are deducted and withheld and paid to the applicable Governmental Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

Article 3

TITLE AND ENVIRONMENTAL MATTERS

Section 3.1 Title and Environmental Matters.

(a) Purchaser hereby acknowledges and agrees without limitation of Purchaser’s rights under the R&W Insurance Policy, prior to Closing, this Article 3, the conditions to closing set forth in Article 8, and the rights and remedies set forth in Article 11 and Article 12, set forth Purchaser’s sole and exclusive remedy against any member of the Seller Group with respect to (A) any Defect, (B) the failure of Seller or any other Person to have title to any of the Assets (whether Defensible Title or otherwise) and (C) the existence of any Environmental Defect, Environmental Liabilities, Release of Hazardous Substances or any other environmental condition with respect to the Assets.

-35-

(b)Special Warranties of Title in the Conveyances.

(i)The Conveyances delivered at Closing shall contain a special warranty of Defensible Title by Seller whereby Seller warrants Defensible Title to Seller’s right, title and interest in the Wells and DSUs set forth on Exhibit A-2 and Exhibit A-5, as applicable, solely to the extent such Wells and DSUs have a positive Allocated Value, conveyed thereunder unto Purchaser against every Person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under Seller but not otherwise, subject, however, to the Permitted Encumbrances. The special warranty of Defensible Title contained in the Conveyances and this Section 3.1(b) shall be subject to the further limitations and provisions of this Article 3, mutatis mutandis, excluding the Defect Deadline, the Individual Defect Threshold and the Defect Deductible.

(ii)As a condition to asserting a valid claim for a breach of Seller’s special warranty of Defensible Title set forth in the Conveyances, no later than the date that is the earlier of (x) twelve (12) months after the Closing Date and (y) the date on which the aggregate of all valid claims related to a breach of Seller’s special warranty of Defensible Title set forth in the Conveyances equals the lesser of (1) the RWI Deductible and (2) the Holdback Amount (the “SWT Deadline”), and without limiting any recourse for Purchaser pursuant to the R&W Insurance Policy with respect to the representations and warranties in Section 4.25, for periods following the SWT Deadline, Purchaser may furnish Seller a Defect Notice meeting the requirements of Section 3.2(a) setting forth any matters that Purchaser asserts as a breach of the special warranty of Defensible Title set forth in the Conveyances. Seller shall have a reasonable opportunity, but not the obligation, to cure prior to the date that is ninety (90) days after the delivery of the Defect Notice, any Title Defect asserted by Purchaser pursuant to this Section 3.1(b).

(iii)For purposes of the special warranties of Defensible Title contained in the Conveyances, the value of the Assets set forth in the exhibits thereto, as applicable, shall be deemed to be the Allocated Value thereof, as adjusted herein. Recovery on the special warranty of Defensible Title contained in the Conveyances shall be limited to an amount (without any interest accruing thereon) equal to the reduction to the Unadjusted Purchase Price to which Purchaser would have been entitled had Purchaser asserted the Title Defect giving rise to such breach of the special warranty of Defensible Title contained in the Conveyances, as applicable, as a Title Defect prior to Closing pursuant to Section 3.2 in each case without taking into account the Individual Defect Threshold and the Defect Deductible.

Section 3.2 Defects; Adjustments.

(a) Notice of Defects. As a condition to Purchaser asserting any claim with respect to any alleged Defect, Purchaser must deliver a valid Notice or Notices (each a “Defect Notice”) with respect to such alleged Defect to Seller on or before 5:00 p.m. Central Time on December 18, 2023 (the “Defect Deadline”); provided that Purchaser shall use commercially reasonable efforts to provide to Seller weekly written updates (which may be amended or supplemented by a Defect Notice) that describe any alleged Defects identified by or on behalf of Purchaser or Purchaser’s Representatives during the prior calendar week; provided further, that Purchaser’s failure to provide such preliminary notices with respect to any Defect shall not prejudice or restrict in any respect Purchaser’s right to subsequently assert such Defect on or before the Defect Deadline, nor shall such failure be a breach of this Agreement. In order to be a valid Defect Notice as to each alleged Defect, each such notice shall be in writing and must include the following:

(i)a description of the alleged Defect;

-36-

(ii)the Well or DSU and Subject Formation(s) subject to such alleged Defect;

(iii)the Allocated Value of the Well or DSU subject to such alleged Defect;

(iv)Purchaser’s good faith estimate of the Defect Amount attributable to such alleged Defect and the computations and information upon which Purchaser’s estimate is based;

(v)all Reasonable Documentation in Purchaser’s or Purchaser’s Representatives possession or reasonable control and relied upon by Purchaser in supporting Purchaser’s assertion and claim of such alleged Defect; and

(vi)with respect to any alleged Environmental Defect, if applicable, reference to applicable Environmental Laws (or permits issued thereunder) that Purchaser alleges have been violated or that Purchaser believes require Remediation with respect to the applicable Assets.

SUBJECT TO PURCHASER’S RIGHTS HEREUNDER WITH RESPECT TO BREACHES OF THE SPECIAL WARRANTY OF DEFENSIBLE TITLE SET FORTH IN THE CONVEYANCES, AND WITHOUT LIMITATION OF PURCHASER’S RIGHTS UNDER THE R&W INSURANCE POLICY, AND SUBJECT TO THE CONDITIONS TO CLOSING SET FORTH IN Article 8, AND THE RIGHTS REMEDIES SET FORTH IN Article 11 AND Article 12), PURCHASER SHALL BE DEEMED TO HAVE WAIVED AND RELEASED, AND COVENANTS THAT IT SHALL WAIVE AND RELEASE, ANY AND ALL DEFECTS (AND ANY ADJUSTMENTS TO THE UNADJUSTED PURCHASE PRICE ATTRIBUTABLE THERETO) FOR WHICH SELLER HAS NOT RECEIVED ON OR BEFORE THE DEFECT DEADLINE A DEFECT NOTICE THAT SATISFIES ALL OF THE CONDITIONS AND REQUIREMENTS SET FORTH IN THIS SECTION 3.2(A) (PROVIDED THAT, WITH RESPECT TO THE ITEMS SET FORTH IN SECTION 3.2(A)(V), SUCH DEFECT NOTICE SHALL BE DEEMED TO HAVE SATISFIED THE REQUIREMENTS SET FORTH THEREIN IF THE SAME COMPLIES WITH SUCH PROVISION IN ALL MATERIAL RESPECTS).

-37-

(b)Notice of Title Benefits. As a condition to Seller asserting any claim with respect to any alleged Title Benefit, should Seller discover any Title Benefit at any time on or prior to the Defect Deadline, Seller shall have the right, but not the obligation, but in no event later than the Defect Deadline, to deliver to Purchaser a written notice (each a “Title Benefit Notice”), which Title Benefit Notice shall include:

(i)a description of the alleged Title Benefit;

(ii)the Well or DSU and the Subject Formation(s) subject to such alleged Title Benefit;

(iii)the Allocated Value of the Well or DSU subject to such alleged Title Benefit;

(iv)Seller’s good faith reasonable estimate of the Title Benefit Amount attributable to such alleged Title Benefit and the computations and information upon which such Party’s estimate is based;

(v)Supporting documents reasonably necessary for Purchaser and the Defect Referee (as well as any title attorney or examiner hired by any such Persons) to verify or investigate the existence of the alleged Title Benefit; and

(vi)SELLER SHALL BE DEEMED TO HAVE WAIVED AND RELEASED, AND COVENANTS THAT IT SHALL WAIVE AND RELEASE, ANY AND ALL TITLE BENEFITS (AND ANY ADJUSTMENTS TO THE UNADJUSTED PURCHASE PRICE ATTRIBUTABLE THERETO) FOR WHICH SELLER HAS NOT SENT TO PURCHASER ON OR BEFORE THE DEFECT DEADLINE A VALID NOTICE THAT SATISFIES ALL OF THE CONDITIONS AND REQUIREMENTS SET FORTH IN THIS Section 3.2(b) (PROVIDED THAT, WITH RESPECT TO THE ITEMS SET FORTH IN SECTION 3.2(B)(V), SUCH DEFECT NOTICE SHALL BE DEEMED TO HAVE SATISFIED THE REQUIREMENTS SET FORTH THEREIN IF THE SAME COMPLIES WITH SUCH PROVISION IN ALL MATERIAL RESPECTS).

(c) Option to Cure Defects. Seller shall have the right, but not the obligation to attempt, at Seller’s sole cost, to cure or remove, on or prior to the applicable Cure Deadline any alleged Defects asserted in a Defect Notice; provided, however, with respect to any Title Defects that remain uncured as of the Closing, Seller shall be deemed to have elected to cure such Title Defects after Closing unless Seller provides Purchaser written notice indicating otherwise. Alleged Defects shall be deemed to have been cured or removed if Seller and Purchaser agree that, or if there has been a final determination pursuant to Section 3.2(i) that (i) with respect to Title Defects, that the DSUs or Wells, affected by such alleged Defect are free of such Defect as of the applicable Cure Deadline, or (ii) with respect to Environmental Defects, such Environmental Defect has been Remediated as of the applicable Cure Deadline. If any asserted Defect is not cured or removed, or if Seller and Purchaser cannot agree as to whether such Defect has been cured, Remediated, or removed, and it is finally determined by the applicable Defect Referee in accordance with Section 3.2(i) that such Defect is not cured, Remediated, or removed by the Cure Deadline, the Unadjusted Purchase Price shall be adjusted by the Defect Amount attributable to such Defect. Seller’s attempt to cure or remove a Defect shall not constitute an obligation to cure or attempt to cure such Defect or a waiver of Seller’s right to dispute the validity, nature, or value of, or cost to cure, such Defect.

-38-

(d)Defect Amounts. The diminution of value of an Asset attributable to any valid Defect (the “Defect Amount”) as to the applicable Asset affected by such Defect shall be determined as follows:

(i)if Purchaser and Seller agree on the Defect Amount, that amount shall be the Defect Amount;

(ii)if a Title Defect is a Lien that is liquidated in amount, then the Defect Amount with respect to the applicable Well or DSU shall be the amount necessary to be paid to remove the Title Defect from Seller’s interest in the affected Well or DSU;

(iii)if a Title Defect as to the Subject Formation affecting any Well or DSU represents a negative discrepancy between (A) the actual Net Revenue Interest for the Subject Formation as to such Well or DSU and (B) the “Net Revenue Interest” percentage stated on Exhibit A-2 or Exhibit A-5, as applicable, for such Subject Formation as to such Well or DSU, then the Defect Amount shall be equal to the product of (1) the Allocated Value of such Subject Formation as to such Well or DSU multiplied by (2) a fraction, the numerator of which is (x) the remainder of (a) the “Net Revenue Interest” percentage stated on Exhibit A-2 or Exhibit A-5, as applicable, for such Subject Formation as to such Well or DSU minus (b) the actual Net Revenue Interest as to the Subject Formation as to such Well or DSU, and the denominator of which is (y) the “Net Revenue Interest” percentage stated on Exhibit A-2 or Exhibit A-5, as applicable, for the Subject Formation as to such Well or DSU; provided that if the Title Defect does not affect the “Net Revenue Interest” percentage stated on Exhibit A-2 or Exhibit A-5, as applicable, for the Subject Formation as to such Well or DSU throughout its entire productive life, the Defect Amount determined under this Section 3.2(d)(iii) shall be reduced to take into account the applicable time period only;

(iv) if the Title Defect represents an obligation, encumbrance, burden or charge upon or other defect in title to the Subject Formation as to a Well or DSU of a type not described in Section 3.2(d)(i) through Section 3.2(d)(iii), the Defect Amount shall be determined by taking into account the Allocated Value of the Well or DSU so affected, the portion of Seller’s interest in the Subject Formation as to such Well or DSU affected by the Title Defect, the legal effect of the Title Defect, the potential present value economic effect of the Title Defect over the life of the Subject Formation as to such Well or DSU, the values placed upon the Title Defect by Purchaser, the estimated capital and operational costs and expenses (or reduction or increases thereof) attributable to Seller’s Working Interest, and such other reasonable factors as are necessary to make a proper evaluation and determination of such value;

-39-

(v)if a Defect is an Environmental Defect, the Defect Amount shall be equal to the estimated cost to Remediate the Asset subject to such Environmental Defect in the lowest-cost manner reasonably available, consistent with applicable Environmental Laws taking into account that non-permanent remedies (including mechanisms to contain or stabilize Hazardous Substances, including monitoring site conditions, natural attenuation, risk-based corrective action, institutional controls, or other appropriate restrictions on the industrial use of the property, caps, dikes, encapsulation, leachate collection systems, and the like), if such responses are appropriate and allowed under Environmental Laws, may be the lowest-cost manner reasonably available; provided, however, such Defect Amount shall expressly exclude (A) the costs, fees and expenses of Purchaser’s and/or its Affiliate’s employees or Purchaser’s project managers or attorneys, (B) costs, fees and expenses for matters that are ordinary costs of doing business regardless of the presence of an Environmental Defect (e.g., those costs that would ordinarily be incurred in the day-to-day operations of the Assets or in connection with permit renewal or amendment (but not modification) activities), (C) overhead costs of Purchaser or its Affiliates, and (D) any Remediation costs, fees or expenses charged or chargeable solely to any other Working Interest owner or co-tenant or joint owner of the underlying Assets burdened by such Environmental Defect;

(vi)the Defect Amount with respect to a Defect shall be determined without duplication of any costs or losses included in another Defect Amount hereunder, or for which Purchaser otherwise receives credit in the calculation of the Adjusted Purchase Price; and

(vii)notwithstanding anything to the contrary in this Agreement, with respect only to Title Defects, the aggregate adjustment to the Unadjusted Purchase Price for all Defect Amounts attributable to all Title Defects affecting a single Asset shall not exceed the Allocated Value of the same (after giving effect to any applicable adjustments due to prior Title Defects), except with respect to those Title Defects contemplated by Section 3.2(d)(ii).

-40-

(e)Title Benefit Amounts. The “Title Benefit Amount” for any Title Benefit shall be determined as follows:

(i) if a Title Benefit applicable to any Subject Formation as to any Well or DSU represents a positive discrepancy between (A) the actual Net Revenue Interest for such Subject Formation as to such Well or DSU and (B) the Net Revenue Interest percentage stated on Exhibit A-2 or Exhibit A-5, as applicable, for such Subject Formation as to such Well or DSU, and in such case there is a proportionate increase in the actual Working Interest with respect to the applicable Subject Formation as to such Well or DSU, as applicable, from the Working Interest stated on Exhibit A-2 for Seller with respect to such Subject Formation or for such Well or Exhibit A-5 with respect to the Subject Formation for such DSU, as applicable, then the Title Benefit Amount shall be equal to the product of (1) the Allocated Value of such Subject Formation as to such Well or DSU multiplied by (2) a fraction, the numerator of which is (x) the remainder of (a) the actual Net Revenue Interest of such Subject Formation as to such Well or DSU minus (b) the Net Revenue Interest percentage stated on Exhibit A-2 or Exhibit A-5, as applicable, for such Subject Formation as to such Well or DSU, and the denominator of which is (y) the Net Revenue Interest percentage stated on Exhibit A-2 or Exhibit A-5, as applicable, for such Subject Formation as to such Well or DSU; provided that if the Title Benefit does not affect the Net Revenue Interest percentage stated on Exhibit A-2 or Exhibit A-5, as applicable, for such Subject Formation as to such Well or DSU throughout its entire productive life, the Title Benefit Amount determined under this Section 3.2(c)(i) shall be reduced to take into account the applicable time period only; and

(ii)if the Title Benefit represents a benefit of a type not described in Section 3.2(e)(i), the Title Benefit Amount shall be determined by taking into account the Allocated Value of the Well or DSU so affected, the portion of Seller’s interest in the Well or DSU affected by the Title Benefit, the legal effect of the Title Benefit, the potential positive economic effect of the Title Benefit over the life of the affected Well or DSU, the values placed upon the Title Benefit by Purchaser and Seller and such other reasonable factors as are necessary to make a proper evaluation and determination of such value.

(f)Individual Defect Threshold and Defect Deductibles. Notwithstanding anything to the contrary in this Agreement:

(i)except as otherwise provided in this Section 3.2(f)¸there shall be no adjustments to the Unadjusted Purchase Price under Section 3.2(g) for any Defect to the extent that the finally determined or agreed Defect Amount for such Defect is less than the Individual Defect Threshold (it being agreed that the Individual Defect Threshold represents a threshold and not a deductible);

(ii)with respect to all valid and finally determined or agreed Defects with respect to the applicable Asset where the finally determined or agreed Defect Amount thereof exceeds the Individual Defect Threshold, there shall be no adjustment to the Unadjusted Purchase Price under Section 3.2(g) with respect to any and all such Defects unless and until the aggregate of all such Defect Amounts with respect thereto exceeds the Defect Deductible, and then only to the extent such aggregate amount exceeds the Defect Deductible (it being the intention of the Parties that the Defect Deductible represents a deductible and not a threshold);

-41-

(iii) notwithstanding anything herein to the contrary, if a single Title Defect affects multiple Wells or DSUs, then the Defect Amounts with respect to such Title Defect as to all such Wells or DSUs, as applicable, shall be aggregated for purposes of calculating, whether the Defect Amount associated with such Title Defect exceeds the Individual Defect Threshold;

(iv)notwithstanding anything herein to the contrary, the Individual Defect Threshold and the Defect Deductible shall not apply to any recourse under this Agreement or the Conveyances with respect to any Special Warranty Defect; and

(v)the Parties agree that for purposes of calculating the Individual Defect Threshold pursuant to this Section 3.2(f), if an Environmental Defect which is not a physical condition affects multiple properties or Assets (e.g., the failure to obtain the same type of permit required under applicable Environmental Laws or the failure to prepare and file the same type of plan (including spill, prevention, control, and countermeasure plans) reports or other regulatory filings), then the Defect Amounts associated with such Environmental Defect that is common across multiple Assets may be aggregated for purposes of meeting the Individual Defect Threshold.

(g)Sole and Exclusive Remedies for Defects. Subject to Section 3.2(i) and Seller’s right to cure, Remediate, and/or dispute the existence of a Defect and the Defect Amount asserted with respect thereto, in the event that any valid Defect is not waived in writing by Purchaser or is not cured or Remediated (and further subject to Purchaser’s right to dispute the validity of such cure or Remediation) on or prior to the applicable Cure Deadline, then:

(i)subject to satisfaction of the Individual Defect Threshold and Defect Deductible pursuant to Section 3.2(f), all Assets subject to any Defects shall be conveyed to Purchaser at Closing and the Unadjusted Purchase Price shall be decreased by the sum of (x) the aggregate finally determined or agreed Defect Amounts attributable to all such finally determined or agreed Title Defects hereunder minus (y) the aggregate finally determined or agreed Title Benefit Amounts attributable to all such finally determined or agreed Title Benefits hereunder, plus the aggregate finally determined or agreed Defect Amounts attributable to all such finally determined or agreed Environmental Defects hereunder, but only to the extent that such aggregate sum with respect to such Defects exceeds the Defect Deductible, it being the intention of the Parties that the Defect Deductible constitutes a deductible and not a threshold; and

(ii) notwithstanding anything herein to the contrary, in lieu of the remedy for Defects set forth in Section 3.2(g)(i), Seller shall have the right, but not the obligation, to elect in writing delivered to Purchaser on or prior to the Closing Date, to exclude the Assets subject to any alleged Defects (along with any other Assets reasonably necessary or desirable for the ownership or operation of such Assets) which either equal or exceed one hundred (100%) of the Allocated Value for such Asset from the transactions contemplated hereunder and, in such event, (A) the Unadjusted Purchase Price shall be decreased by the Allocated Value of such excluded Assets, (B) all such Assets shall be deemed to be excluded from the definition of Assets and from Exhibit A, (C) such Assets shall be deemed to constitute Excluded Assets set forth on Schedule 1.1(b) and (D) Purchaser shall have no rights or obligations hereunder with respect to such Excluded Assets.

-42-

(h)Remedies for Title Benefits. Subject to Purchaser’s right to dispute the existence of a Title Benefit and the Title Benefit Amount asserted with respect thereto, the sole and exclusive remedy of Seller with respect to all finally determined or agreed Title Benefit Amounts attributable to all finally determined or agreed Title Benefits shall be to offset the amount of all finally determined or agreed Defect Amounts solely with respect to Title Defects for purposes of calculating the downward adjustment to the Unadjusted Purchase Price pursuant to Section 3.2(g) and may not result in any standalone adjustment; provided that for the aggregate Title Benefit Amounts attributable to the effects of all Title Benefits of an affected Well or DSU shall not exceed the Allocated Value of the affected Well or DSU, as applicable.

(a)In cases in which the Asset subject to an unobtained Required Consent is an Asset other than an Oil and Gas Property, and Purchaser is assigned the Oil and Gas Property or Oil and Gas Properties to which such Asset relates, but such Asset is not transferred to Purchaser due to the unobtained Required Consent, the Parties shall continue after Closing until the Cut-Off Date to use commercially reasonable efforts to obtain the Required Consent so that such Asset can be transferred to Purchaser upon receipt of the Required Consent, and, if permitted pursuant to applicable Law and agreement, such Asset shall be held by Seller for the benefit of Purchaser, Purchaser shall assume as part of the Assumed Obligations and bear and pay all amounts due thereunder or with respect thereto, and Purchaser shall be responsible for the performance of any obligations and Damages under or with respect to such Asset to the extent that Purchaser has been transferred the Assets necessary to such performance until the applicable Required Consent is obtained.

(b)In cases in which the Asset subject to a Required Consent requirement is an Oil and Gas Property and the Required Consent is not obtained by Closing, then either Party may elect to exclude the Oil and Gas Property subject to such Required Consent (along with any other Assets reasonably necessary or desirable for the ownership or operation of such Oil and Gas Property), in which event, (i) the Unadjusted Purchase Price shall be reduced by the Allocated Value of such excluded Oil and Gas Property and other Assets, (ii) such excluded Oil and Gas Property and other Assets shall be deemed to be deleted from Exhibit A and added to Schedule 1.1(b), and (iii) such excluded Oil and Gas Property and other Assets shall constitute Excluded Assets for all purposes hereunder. If any such Required Consent requirement with respect to which an adjustment to the Unadjusted Purchase Price is made under Section 2.4(b) is subsequently obtained prior to the Cut-Off Date, (A) Seller shall, promptly after such Required Consent requirement is satisfied, convey the applicable Oil and Gas Property and Assets to Purchaser, (B) the Parties shall deliver all instruments and documents that would have been required under the terms hereof to be delivered at Closing with respect to such Oil and Gas Property and Assets, (C) Purchaser shall, simultaneously with the conveyance of the applicable Oil and Gas Property and Assets, pay the amount of any previous deduction from the Unadjusted Purchase Price (subject to all other applicable adjustments with respect to such Oil and Gas Properties and Assets under Section 2.4 to Seller), and (D) such Oil and Gas Property and Assets shall no longer be deemed to be (1) deleted from Exhibit A, (2) added to Schedule 1.1(b), or (3) Excluded Assets for any purposes hereunder.

Section 7.5 Preferential Rights.

(a)Any Preferential Rights must be exercised subject to all terms and conditions set forth in this Agreement, including the successful Closing of this Agreement pursuant to Article 9 on the terms set forth herein. The consideration payable under this Agreement for any particular Asset for purposes of Preferential Rights notices shall be the Allocated Value for such Asset, adjusted as set forth herein.

(b)If any Preferential Right as to any Assets is validly exercised prior to Closing, then (i) the Unadjusted Purchase Price shall be reduced by the Allocated Value of such Asset, (ii) such Assets shall be deemed to be deleted from Exhibit A and added to Schedule 1.1(b), and (iii) such Assets shall constitute Excluded Assets for all purposes hereunder; provided, however, in the event the holder of any Preferential Right as to any Assets validly exercises such Preferential Right prior to Closing but refuses or fails to consummate the purchase of such Assets on or before the Cut-Off Date, then (A) Seller shall promptly convey the applicable Assets to Purchaser, (B) the Parties shall deliver all instruments and documents that would have been required under the terms hereof to be delivered at Closing with respect to such Assets, (C) Purchaser shall, simultaneously with the conveyance of the applicable Assets, pay the amount of any previous deduction from the Unadjusted Purchase Price (subject to all other applicable adjustments with respect to such Assets under Section 2.4) to Seller, and (D) such Assets shall no longer be deemed to be (1) deleted from Exhibit A, (2) added to Schedule 1.1(b), or (3) Excluded Assets for any purposes hereunder.

(c)Should a Third Party fail to validly exercise or waive its Preferential Right to purchase as to any portion of the Assets prior to Closing, and the time for exercise or waiver of such Preferential Right has not yet expired, then (i) the Unadjusted Purchase Price shall not be reduced by the Allocated Value of such Assets, (ii) such Assets shall be included in the Assets and conveyed by Seller to Purchaser at Closing, (iii) from and after Closing, Purchaser shall be entitled to all amounts payable by such holder in connection with such Preferential Right, and (iv) from and after Closing, Purchaser shall comply with, be responsible for and perform all obligations arising with or attributable to such Preferential Right.

-65-

(d) The Parties acknowledge and agree that Seller desires to sell all of its Assets and would not have entered into this Agreement but for Purchaser’s agreement to purchase all of the Assets. Accordingly, it is expressly understood and agreed that Seller does not desire to sell to any Person other than Purchaser any Assets subject to any Preferential Right unless the sale of all of the Assets is consummated by the Closing Date in accordance with the terms of this Agreement and the terms of the applicable Preferential Right to purchase. In furtherance of the foregoing, Seller’s obligation hereunder to sell its Assets subject to any Preferential Right to any Person other than Purchaser is expressly conditioned upon the consummation by the Closing Date of the sale of all of the Assets (other than Excluded Assets) in accordance with the terms of this Agreement, either by conveyance to Purchaser or conveyance pursuant to an applicable Preferential Right; provided that, nothing herein is intended or shall operate to extend or apply any Preferential Right to any portion of such Assets which is not otherwise burdened thereby.

Section 7.6 Casualty and Condemnation. If, after the Execution Date but prior to or on the Closing Date, any portion of the Oil and Gas Properties are destroyed by fire, explosion, wild well, hurricane, storm, weather events, earthquake, act of nature, civil unrest, or similar disorder, terrorist acts, war, or any other hostilities or other casualty or is expropriated or taken in condemnation or under right of eminent domain (each a “Casualty Loss”), Seller shall promptly notify Purchaser in writing describing, in reasonable detail and in good faith, the nature, extent and estimated costs to repair or replace the Assets subject to such Casualty Loss. If (a) (i) the Casualty Loss does not equal or exceed One Million Dollars ($1,000,000), and the Closing thereafter occurs, or (ii) the Casualty Loss equals or exceeds One Million Dollars ($1,000,000), such Casualty Loss is covered by Third Party insurance, and, upon receipt of Seller’s notice, Seller elects to proceed to Closing without an adjustment to the Unadjusted Purchase Price, then, in each case, Seller shall pay to Purchaser at Closing all sums actually paid to Seller by Third Parties by reason of such Casualty Loss insofar as with respect to the Assets and shall assign, transfer and set over to Purchaser or subrogate Purchaser to all of Seller’s or its Affiliates right, title and interest (if any) in insurance claims, unpaid awards, and other rights against Third Parties (excluding any Damages, other than insurance claims, of or against any Seller Group member) arising out of such Casualty Loss insofar as with respect to the Assets; provided, however, that Seller shall reserve and retain (and Purchaser shall assign to Seller) all right, title, interest and claims against Third Parties for the recovery of Seller’s costs and expenses incurred prior to Closing in repairing such Casualty Loss or pursuing or asserting any such insurance claims or other rights against Third Parties, and (b) if the Casualty Loss equals or exceeds One Million Dollars ($1,000,000), upon receipt of Seller’s notice, Seller shall elect to either (i) proceed with the Closing without an adjustment to the Unadjusted Purchase Price, in which case the terms of clause (a)(ii) above shall apply, or (ii) reduce the Unadjusted Purchase Price by the cost and expense to repair or replace the Assets affected by such Casualty Loss. For the avoidance of doubt, for any Casualty Loss that equals or exceeds One Million Dollars ($1,000,000) but is not covered by a Third Party insurance policy, Seller shall reduce the Unadjusted Purchase Price by the cost and expense to repair or replace the Assets affected by such Casualty Loss. If the Parties are unable to agree on the amount of any reduction to the Unadjusted Purchase Price under this Section 7.6 or the preceding sentence, Seller’s good faith and reasonable estimate shall be used for the purposes of adjusting the Unadjusted Purchase Price at Closing, subject to final adjustment in accordance with Section 2.4.

(b)Notwithstanding anything to the contrary in this Section 7.7 or otherwise, no member of the Purchaser Group shall be required to, and shall not be required to cause its Affiliates to (and Seller shall not, and shall not agree to, without Purchaser’s prior written consent) sell, divest, hold separate, license, relinquish, otherwise dispose of, or agree to any limitation on its freedom of action, ownership, or control with respect to any assets, businesses, properties, or interests in or of any Person, or agree or consent to any of the foregoing.

Anything to the contrary in this Section 7.7 notwithstanding, materials provided to the other Party or its outside counsel may be redacted to remove references concerning the valuation of Purchaser or Seller or as necessary to address reasonable privilege or confidentiality concerns. In furtherance and not in limitation of the foregoing, Seller and Purchaser agree not to extend any waiting period under the HSR Act or enter into any agreement with any Governmental Authority not to consummate the transactions contemplated hereby, except with the prior consent of the other Party, not to be unreasonably withheld or delayed. Purchaser shall bear one hundred percent (100%) of all filing fees in connection with any filings made pursuant to the HSR Act in connection with the transactions contemplated hereunder.

Section 7.8 Notifications. Purchaser shall notify Seller in writing promptly after Purchaser obtains knowledge that any representation or warranty of Seller contained in this Agreement is, becomes, or will be untrue in any material respect on or before the Closing Date. Seller shall notify Purchaser in writing promptly after Seller obtains knowledge that any representation or warranty of Purchaser contained in this Agreement is, becomes, or will be untrue in any material respect on or before the Closing Date. It is understood and agreed that the delivery of any notice required under this Section 7.8 shall not in any manner constitute a waiver by any Party of any conditions precedent to the Closing hereunder.

Section 7.9 Liability for Brokers’ Fees. Each Party hereby agrees to indemnify, defend and hold harmless the other Party, any Affiliate of such other Party, and all such other Party’s stockholders, members, officers, directors, employees, agents, lenders, advisors, representatives, accountants, attorneys and consultants from and against any and all claims, obligations, damages, liabilities, losses, costs and expenses (including court costs and reasonable attorneys’ fees) arising as a result of undertakings or agreements of any such Indemnifying Party (or any of its Affiliates) prior to Closing, for brokerage fees, finder’s fees, agent’s commissions or other similar forms of compensation to an intermediary in connection with the negotiation, execution or delivery of this Agreement or any agreement or document contemplated hereunder.

Section 7.10 Press Releases. From and after the Execution Date, neither Party shall make, and shall cause each of its Affiliates not to make, any press release or public disclosure regarding the existence of this Agreement, the contents hereof or the transactions contemplated hereby, or the identities of any Parties hereto without the prior written consent of the other Party (with such consent not to be unreasonably withheld, delayed, or conditioned); provided, however, the foregoing shall not restrict disclosures by Purchaser or any of its Affiliates (a) to the extent that such disclosures are required by applicable securities or other Laws or the applicable rules of any stock exchange having jurisdiction over Purchaser or Affiliate of Purchaser or (b) to Governmental Authorities or any Third Party holding Preferential Rights to purchase, rights of consent, or other rights that may be applicable to the transactions contemplated by this Agreement, as reasonably necessary to provide notices, seek waivers, amendments, or terminations of such rights, or seek such consents. Purchaser shall be liable for the compliance of Purchaser’s Affiliates with the terms of this Section 7.10.

Section 7.11 Credit Support. The Parties agree and acknowledge that except as expressly provided in this Section 7.11, none of the Credit Support provided by or on behalf of any member of the Seller Group in support of the obligations of any member of the Seller Group related to the ownership or operation of the Assets shall be included in or constitute any Assets or be transferred to the Purchaser at Closing. At or prior to the Closing, Purchaser shall post and provide any and all Credit Support set forth on Schedule 4.15 necessary to obtain the release, return, and replacement of all Credit Support provided by or on behalf of any member of the Seller Group in support of the obligations of any member of the Seller Group related to the ownership or operation of the Assets, with each such release and replacement in the form and substance satisfactory to Seller. At the Closing, Purchaser shall cause the return or reimbursement of Seller for any cash deposits constituting Credit Support that are provided, funded, or otherwise supported by any member of the Seller Group with respect to the Assets to be assigned hereunder by Seller.

(c)Upon the occurrence of Closing, as promptly as practicable, but in any case within sixty (60) days after the Closing Date, Purchaser shall eliminate the names “Excalibur”, “Travis Peak”, “Paloma”, “TPR Mid-Continent” and any variants thereof from the Assets acquired pursuant to this Agreement and, except with respect to such grace period for eliminating existing usage, shall have no right to use any logos, trademarks, or trade names belonging to Seller or any of its Affiliates.

Section 7.13 Records.

(a)As of the Execution Date, Seller shall provide Purchaser access to the Records consistent with Section 7.1(a); provided, however, that Seller shall make available to Purchaser no later than five (5) Business Days following the Closing Date the physical Records that are in the possession of Seller for pickup, during normal business hours, at Purchaser’s cost.

(b)Notwithstanding anything to the contrary herein, Seller shall be authorized to make copies of or retain the originals of those certain Records relating to Asset Tax and accounting matters and provide Purchaser, at its request, with copies of such Records (i) that pertain to Asset Tax matters solely related to the Assets or (ii) if such Records are necessary for Purchaser to adequately prepare Tax Returns or to contest a legal or administrative proceeding pursuant to Article 10.

After such seven (7) year period, before Purchaser shall dispose of any such Records, Purchaser shall give Seller at least sixty (60) days’ Notice to such effect, and Seller shall be given an opportunity, at Seller’s sole cost and expense, to remove and retain all or any part of such Records as Seller may select.

Section 7.14 Personnel Matters.

(a) Seller has provided Purchaser a list of certain individuals and entities engaged by a Seller Entity or an Affiliate of Seller to provide field services to the Assets (each, a “Service Provider”). Purchaser may offer to engage any Service Provider (each, a “Service Provider Offer”) on terms and conditions in its sole discretion, subject to compliance with applicable Law and the timing requirements set forth below. To the extent Purchaser timely informs Seller of its desire to assume the contract with Seller or its Affiliate applicable to any Service Provider, Seller shall take, or shall cause its Affiliate, as applicable, to take, reasonable best efforts to assign such contract to Purchaser, provided that the contract permits such assignment. Seller shall not, and shall cause its Affiliates not to, interfere with Purchaser’s and its Affiliates’ reasonable efforts to interview each such Service Provider and determine the nature and extent of such Service Provider’s continuation with Purchaser or its Affiliates, if any. At least thirty (30) days prior to the Closing, Seller shall provide to Purchaser contact information for Third Party service providers (including the Service Providers) providing contingent personnel to the operation of the Assets and shall not interfere with Purchaser’s effort to retain such contingent work force. Purchaser shall make all Service Provider Offers no later than ten (10) days prior to the Closing Date. Within two (2) Business Days of extending any Service Provider Offer, Purchaser shall notify Seller of such offers. Within two (2) Business Days of any Service Provider’s acceptance or rejection of a Service Provider Offer, Purchaser shall notify Seller of such acceptance or rejection. With respect to any Service Provider who accepts a Service Provider Offer, Purchaser shall, or shall cause its post-Closing Affiliate to, engage such Service Provider effective as of the Closing. Purchaser shall retain, and indemnify and hold Seller harmless from, all liabilities with respect to Purchaser’s selection, offer and retention process with respect to the Service Providers.

(b) Following the Closing and for a period of twelve (12) months, Purchaser shall not, and shall cause its Affiliates not to, directly or indirectly, solicit, induce, employ or engage any Person listed on Schedule 7.14(b) (collectively, the “Restricted Persons”) to terminate his or her employment or engagement with Seller or its Affiliates, or to otherwise alter such individual’s relationship with Seller or its Affiliates; provided that, (i) a general solicitation not directed at any Restricted Persons shall not, on its own, be deemed a breach of this Section 7.14(b), so long as neither Purchaser nor any of its Affiliates hire any Restricted Person who responds to such solicitation and (ii) nothing herein shall prohibit Purchaser or its Affiliates from soliciting, hiring or engaging any Restricted Person whose employment with the Seller or their Affiliates, as applicable, ended more than six (6) months prior to Purchaser taking such action. Purchaser acknowledges and agrees that the restrictions contained in this Section 7.14(b) are reasonable and necessary to protect the legitimate interests of Seller and constitute a material inducement to Seller to enter into this Agreement. The Parties agree that, if any court of competent jurisdiction finally determines that a specified time period, limitation or any other relevant feature of this Section 7.14(b) is unreasonable, arbitrary, against public policy or otherwise unenforceable under the circumstances, then any such provision shall, for purposes of such jurisdiction and circumstances only, be revised by such court to a lesser period of time, limitation or other relevant feature, as the case may be, which is determined by such court to be as close to the original provision as possible and enforceable against the Purchaser and its Affiliates under the circumstances, and such provision shall be enforced accordingly.

-70-

(c)The provisions of this Section 7.14 are for the sole benefit of the Parties and nothing herein, expressed or implied, is intended or will be construed to confer upon or give to any Person (including, for the avoidance of doubt, any Service Provider or any other current or former employee or service provider of a member of any Seller Entity, Seller or any of its respective Affiliates), other than the Parties and their respective permitted successors and assigns, any third party beneficiary, legal or equitable or other rights or remedies (including with respect to the matters provided for in this Section 7.14) under or by reason of any provision of this Section 7.14.

Section 7.15 Additional Leases.

(a)If at any time from and after the Effective Time until 5:00 p.m. Central Time on the date that is five (5) Business Days prior to the Closing Date (the “Additional Lease Acquisition Deadline”), any Seller Entity may acquire title to any Additional Lease located within the geographic areas identified on Schedule 7.15(a) (each such area, an “Acquisition Area”, and any such acquisition an “Additional Lease Acquisition”). For purposes hereof, the term “Additional Lease” means a Hydrocarbon lease that satisfies all of the following criteria: (i) is acquired by any Seller Entity after the Effective Time (including any such interests acquired under a recordable lease or agreement but not yet filed of record), (ii) burdens one or more Subject Formations located within the Acquisition Area, (iii) is held by production or has a primary term that does not expire prior to June 30, 2025, (iv) entitles the lessee thereunder to a Net Revenue Interest in the applicable Subject Formation(s) equal to or greater than the product of (A) seventy five percent (75%) multiplied by (B) the lessee’s Working Interest in such lease as to such Subject Formation(s), (v) does not include a prohibition on pooling or allocation wells and (vi) as of the Closing Date is free and clear of all Liens other than Permitted Encumbrances; provided, however, an “Additional Lease” shall not include any leases that cure any Title Defects.

(b)If any Seller Entity acquires an Additional Lease prior to the Additional Lease Acquisition Deadline, Seller shall deliver to Purchaser no later than the Additional Lease Acquisition Deadline a written notice (“Additional Lease Notice”) which (i) identifies such Additional Lease(s), including a copy of such Additional Lease(s), (ii) sets forth such Seller’s good faith estimate of the number of Net Leasehold Mineral Acres as to each applicable Subject Formation burdened by each such Additional Lease, (iii) sets forth such Seller Entity’s Additional Lease Acquisition Costs with respect to such Additional Lease, and (iv) includes copies of title abstracts, title information, and any other supporting documents in such Seller Entity’s possession that are reasonably necessary for the Purchaser to verify or confirm such Seller Entity’s title to each such Additional Lease.

-71-

(c)The Additional Leases acquired by the Seller Entities after the Execution Date shall be included in and constitute Leases as of the Closing Date and the Adjusted Purchase Price at Closing shall be increased by the Additional Lease Acquisition Costs attributable to all such Additional Leases. The Seller and Purchaser shall use good faith efforts to agree on the validity and determination of all Additional Leases and Additional Lease Acquisition Costs with respect thereto. If the Parties are unable to agree on whether a Hydrocarbon lease constitutes an Additional Lease, the existence or amount of any Additional Leases and Additional Lease Acquisition Costs, or any other matter related to title to any Additional Leases for which the applicable Seller Entity has delivered an Additional Lease Notice then all such disputed matters, interpretations and effect of this Section 7.15 shall be exclusively and finally resolved by the Title Referee in accordance with the terms of Section 3.2(i), mutatis mutandis.

Section 7.16 R&W Insurance Policy. The Parties acknowledge and agree that, as of or prior to the Execution Date, the Purchaser has procured the R&W Conditional Binder in connection with the R&W Insurance Policy. Following the Execution Date, the Purchaser shall use commercially reasonable efforts to satisfy the conditions set forth in the R&W Conditional Binder to cause the R&W Insurance Policy to be issued on the terms and in the form attached hereto as Exhibit G as soon as reasonably practicable following the Closing, including payment of all costs of such R&W Insurance Policy. Seller agrees to use commercially reasonable efforts to assist Purchaser in its efforts to satisfy the conditions set forth in the R&W Conditional Binder, including providing such information, data, Records, or other reasonable information reasonably requested by the underwriters of such R&W Insurance Policy. The Purchaser will not amend, modify, supplement, or restate the provisions of Section XIII.B of the R&W Insurance Policy attached hereto as Exhibit G benefitting the Seller, its Affiliates, and its and their respective Representatives in any manner or respect adverse to such parties without the prior written consent of Seller. Purchaser shall provide Seller with a true and complete copy of the final and issued R&W Insurance Policy as soon as reasonably practicable following the Closing. The Parties acknowledge and agree that any failure by Purchaser to obtain or maintain the R&W Insurance Policy in accordance with this Section 7.16 shall not in any manner increase any liability of Seller or any of its Affiliates or representatives under this Agreement, including if (x) the R&W Insurance Policy is disputed, invalidated or deemed ineffective, in whole or in part, or (y) the coverage provided under the R&W Insurance Policy is denied, disputed, exhausted or otherwise made unavailable to Purchaser or its Affiliates, in whole or in part. For the avoidance of doubt, the Parties acknowledge and agree that (i) the procurement by Purchaser of the R&W Insurance Policy is not a condition to Closing and (ii) all costs and expenses with respect to obtaining the R&W Insurance Policy, including the total premium, underwriting costs, Taxes, brokerage commission, and other costs and expenses of such policy, will be borne fifty percent (50%) by Purchaser, and fifty percent (50%) by Seller.

Section 7.17 Financial Statement Cooperation.

(a)During the period beginning on the Execution Date and ending on the date that is eighteen (18) months after the Closing Date (the “Cooperation Period”), Seller shall reasonably cooperate with the Purchaser and its Representatives, at the Purchaser’s sole cost and expense, during normal business hours, in connection with the preparation by Purchaser of any statements, forms, schedules, reports or other documents filed or furnished with the SEC or any other Governmental Authorities as are required of Purchaser (or its potential successors) under applicable Laws, which involve or otherwise incorporate the Assets.

-72-

(b) Seller acknowledges that Purchaser and/or its Affiliates or potential successors may be required to prepare audited and interim financial statements, including pro forma financial statements, relating to the Assets pursuant to the Securities Act, and the rules and regulations promulgated thereunder (including the rules and regulations set forth in Regulation S-X) or as may be needed to satisfy applicable disclosure requirements thereunder. Upon written request (email being sufficient) by Purchaser, Seller shall prepare and deliver, at the Purchaser’s sole cost and expense, (i) audited financial statements of the Assets at and for the fiscal years ended December 31, 2021 and December 31, 2022 (and if the Closing Date does not occur on or prior to December 31, 2023, audited financials of the Assets at and for the fiscal year ended December 31, 2023), and (ii) unaudited financial statements of the Assets at September 30, 2023 and for the periods ending on September 30, 2022 and September 30, 2023, in each case, and if requested, as soon as reasonably practicable. The Purchaser shall be responsible for all Third Party costs and expenses incurred in the preparation of any such financial statements whether incurred by the Purchaser or Seller (or any of its Affiliates). During the Cooperation Period, Seller shall provide the Purchaser and its Representatives reasonable access during normal business hours to such historic financial statements, records (to the extent such information is available), and personnel of Seller and its subsidiaries’ accounting firms as the Purchaser may reasonably request to enable the Purchaser and their Representatives to prepare any such financial statements.

(c)During the Cooperation Period, Seller shall use commercially reasonable efforts to cause the personnel of Seller and its subsidiaries, and to request its independent auditors, reserve engineers and other applicable consultants or service providers, to reasonably cooperate with the Purchaser and its Representatives in the interpretation, preparation, and disclosure of any such financial statements, including pro forma financial statements, or reserve information in accordance with this Section 7.17, in each case, at Purchaser’s sole cost and expense. During the Cooperation Period and for one (1) year thereafter (the “Comfort Period”), Seller shall use commercially reasonable efforts to request its independent auditors and reserve engineers to, at the Purchaser’s sole cost and expense, (i) provide customary “comfort letters,” reports, letters and consents, including issuing any customary representation letters in connection therewith to each such auditor or reserve engineer, to any underwriter or purchaser in a securities offering by Purchaser or its Affiliates and consent to the inclusion or incorporation by reference of its audit opinion or report with respect to any audited financial statements or reserve information, as applicable, (ii) consent to be named an expert in any offering memorandum, private placement memorandum or prospectus used by Purchaser or its Affiliates or any filing by Purchaser with the SEC, and (iii) provide access to the Purchaser and its Representatives to the work papers of Seller’s independent auditors and reserve engineers, all in accordance with this Section 7.17. All of the information provided by Seller and its Affiliates pursuant to this Section 7.17 is given without any representation or warranty, express or implied, and neither Seller nor any of its Affiliates or its or their respective accountants shall have any liability or responsibility with respect thereto. Without limiting the generality of the foregoing sentence, Purchaser shall indemnify, defend and hold harmless the Seller Group from and against any and all Damages, liabilities or losses suffered or incurred arising from the financial statements prepared and delivered and/or the cooperation provided by the Seller Group pursuant to this Section 7.17 (other than to the extent such liabilities arise from actual fraud or willful misconduct of Seller or their Affiliates or any of their respective Representatives) and any information utilized in connection therewith.

(b)If the Closing occurs, the Parties will jointly instruct the Escrow Agent to retain from the initial Deposit an amount equal to Ten Million Dollars ($10,000,000) (the “Holdback Amount”) in the Escrow Account in support of Seller’s obligations in respect of the Holdback Matters.

(e)On the first Business Day following December 15, 2024 (the “Holdback Release Date”), Purchaser and Seller shall jointly execute and deliver to the Escrow Agent written instructions instructing the Escrow Agent to release and deliver to Seller an amount in cash equal to the remaining Holdback Amount (and all earnings thereon) less the aggregate amount of all unresolved and/or unsatisfied claims that Purchaser has made in good faith in writing to Seller in respect of a Holdback Matter.

TAX MATTERS

Section 10.1Asset Taxes.

(a)Solely for the purpose of determining the amount of Asset Taxes in connection with the application of Section 2.4 and Section 2.6, Seller shall be allocated and bear all Asset Taxes attributable to (i) any Tax period ending prior to the Effective Time and (ii) the portion of any Straddle Period ending immediately prior to the Effective Time, and Purchaser shall be allocated and bear all Asset Taxes attributable to (x) any Tax period beginning at or after the Effective Time and (y) the portion of any Straddle Period beginning at the Effective Time.

(b) Solely for purposes of determining the allocations described in Section 10.1(a), (i) Asset Taxes that are attributable to the severance or production of Hydrocarbons (other than, for the avoidance of doubt, Asset Taxes that are ad valorem, property, and similar Asset Taxes imposed on a periodic basis) shall be allocated to the period in which the severance or production giving rise to such Asset Taxes occurred, (ii) Asset Taxes that are based upon or related to sales or receipts or imposed on a transactional basis (other than such Asset Taxes described in clause (i) above or that are ad valorem, property and similar Asset Taxes imposed on a periodic basis), shall be allocated to the period in which the transaction giving rise to such Asset Taxes occurred, and (iii) Asset Taxes that are ad valorem, property or similar Asset Taxes imposed on a periodic basis pertaining to a Straddle Period shall be allocated between the portion of such Straddle Period ending immediately prior to the Effective Time and the portion of such Straddle Period beginning at the Effective Time by prorating each such Asset Tax based on the number of days in the applicable Straddle Period that occur before the date on which the Effective Time occurs, on the one hand, and the number of days in such Straddle Period that occur on or after the date on which the Effective Time occurs, on the other hand. For purposes of applying this Section 10.1(b) to Asset Taxes that are ad valorem, property and similar Asset Taxes imposed on a periodic basis, the period for such Asset Taxes shall begin on the date on which ownership of the applicable Assets gives rise to liability for the particular Asset Tax and shall end on the day before the next such date.

-81-

(c)To the extent the actual amount of an Asset Tax is not known at the time an adjustment is to be made with respect to such Asset Tax pursuant to Section 2.4 or Section 2.6, as applicable, the Parties shall utilize the most recent information available in estimating the amount of such Asset Tax for purposes of such adjustment.

(d)If (i) the actual amount of an Asset Tax (or the amount thereof paid or economically borne by a Party) is ultimately determined to be different than the amount (if any) that was taken into account in connection with the determination of the Adjusted Purchase Price as finally determined pursuant to Section 2.6, (ii) the Tax Return for such Asset Tax becomes due after the date the Adjusted Purchase Price is finally determined pursuant to Section 2.6 and (iii) such Tax Return is timely filed with the applicable Governmental Authority (taking into account any extensions of time to file such Tax Returns), then timely payments will be made from one Party to the other to the extent necessary to cause each Party to bear the amount of such Asset Tax set forth on such Tax Return (as originally filed) that is allocable to such Party under this Section 10.1.

Section 10.2Transfer Taxes and Recording Fees.

(a)The Parties acknowledge and agree that neither the Unadjusted Purchase Price nor the Adjusted Purchase Price is inclusive of any Transfer Taxes. To the extent that any sales, use, transfer, stamp, documentary, registration, excise, or similar Taxes are payable by reason of the sale of the Assets under this Agreement (“Transfer Taxes”), such Transfer Taxes shall be borne and paid by Purchaser; provided, however, if the Seller is primarily responsible under applicable Law for collecting and remitting any Transfer Taxes, then, at least five (5) Business Days prior to the due date of such Transfer Taxes, Purchaser shall pay the amount of such Transfer Taxes to Seller, and Seller shall remit such Transfer Taxes to the applicable Governmental Authority. Seller and Purchaser shall and shall cause their respective Affiliates to, reasonably cooperate in good faith to minimize, to the extent permissible under applicable Law, the amount of any such Transfer Taxes and timely prepare and file any Tax Returns or other filing relating to such Transfer Taxes, including any claim for exemption or exclusion from the application or imposition of any Transfer Taxes.

(b) Purchaser shall bear and pay all required filing and recording fees and expenses in connection with the filing and recording of the assignments, conveyances, or other instruments required to convey title to the Assets to Purchaser.

For the avoidance of doubt, with respect to any refunds of Asset Taxes received by a Party from a Governmental Authority after the date the final settlement statement is finally determined pursuant to Section 2.6(b), the Party receiving such refund shall not be required to make any payment to the other Party in respect of such refund. If a Party or its Affiliates receives a refund of Asset Taxes to which the other Party is entitled pursuant to this Section 10.3, such recipient Party shall forward to the entitled Party the amount of such refund within thirty (30) days after such refund is received, net of any reasonable costs or expenses incurred by such recipient Party in procuring such refund.

Section 10.4Cooperation. The Parties shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns and any audit, litigation, or other proceeding with respect to Taxes relating to the Assets. Such cooperation shall include the retention and (upon the other Party’s request and expense) the provision of records and information that are relevant to any such Tax Return or audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided under this Agreement. Seller and Purchaser agree to retain all books and records with respect to Tax matters pertinent to the Assets relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations of the respective taxable periods and to abide by all record retention agreements entered into with any Governmental Authority.

Section 10.5Tax Returns. After the Closing Date, excluding any Tax Returns and Asset Taxes required to be filed and/or paid by a Third Party operator, Purchaser shall (a) be responsible for paying any Asset Taxes relating to any (i) Tax period that ends before the Closing Date or (ii) Straddle Period, in each case, that become due and payable after the Closing Date and shall file with the appropriate Governmental Authority any and all Tax Returns required to be filed after the Closing Date with respect to such Asset Taxes and shall use commercially reasonable efforts to (b) submit each such Tax Return to Seller for its review and comment reasonably in advance of the due date therefor, and (c) timely file any such Tax Return, incorporating any reasonable comments received from Seller prior to the due date therefor. The Parties agree that (x) this Section 10.5 is intended to solely address the timing and manner in which certain Tax Returns relating to Asset Taxes are filed and the Asset Taxes shown thereon are paid to the applicable taxing authority, and (y) nothing in this Section 10.5 shall be interpreted as altering the manner in which Asset Taxes are allocated to and economically borne by the Parties (except for any penalties, interest or additions to Tax imposed as a result of any breach by Purchaser of its obligations under this Section 10.5, which shall be borne by Purchaser).

(b) In the event that (x) all conditions precedent to the obligations of Seller set forth in Section 8.1 have been satisfied or waived (to the extent waivable) in writing by Seller (or would have been satisfied except for the breach or failure of Seller’s representations, warranties or covenants hereunder) and (y) the Closing has not occurred solely as a result of the material breach or material failure of Seller’s representations, warranties or covenants hereunder, including, if and when required, Seller’s obligations to consummate the transactions contemplated hereunder at Closing, then Purchaser shall promptly elect in writing, as the sole and exclusive remedy of the Purchaser Group against any member of the Seller Group for the failure to consummate the transactions contemplated hereunder at Closing, to (i) seek specific performance of this Agreement against Seller, or (ii) terminate this Agreement and receive the entirety of the Deposit for the sole account and use of Purchaser; provided, however, if Purchaser elects to seek specific performance of this Agreement against Seller under (i) above but Closing fails to occur, Purchaser may elect to exercise its rights under (ii) above and terminate this Agreement and receive (a) the entirety of the Deposit for the sole account and use of Purchaser plus (b) recover from Seller an aggregate amount equal to Purchaser’s and its Affiliates’ actual, documented out-of-pocket costs and expenses incurred in connection with, or in preparation for, the negotiation, diligence, performance and consummation of the transactions contemplated hereunder at Closing, in an amount up to, but not to exceed Three Million Dollars ($3,000,000).

-84-

(c)In the event that (i) all conditions precedent to the obligations of Purchaser set forth in Section 8.2 have been satisfied or waived (to the extent waivable) in writing by Purchaser (or would have been satisfied except for the breach or failure of any of Purchaser’s representations, warranties or covenants hereunder); and (ii) the Closing has not occurred solely as a result of the breach or failure of any of Purchaser’s representations, warranties, or covenants hereunder, including, if and when required, Purchaser’s obligations to consummate the transactions contemplated hereunder at Closing, then Seller shall be entitled, as the sole and exclusive remedy of the Seller Group against any member of the Purchaser Group for the failure to consummate the transactions contemplated hereunder at the Closing, to terminate this Agreement and receive the entirety of the Deposit for the sole account and use of Seller as liquidated damages hereunder. Seller and Purchaser acknowledge and agree that (i) Seller’s actual damages upon the event of such a termination are difficult to ascertain with any certainty, (ii) the Deposit is a fair and reasonable estimate by the Parties of such aggregate actual damages of Seller, and (iii) such liquidated damages do not constitute a penalty.

(d)In the event that this Agreement is terminated under Section 11.1 (other than Section 11.1(c)) and Seller is not entitled or required to receive the Deposit under Section 11.2(c), Purchaser shall be entitled to receive the entirety of the Deposit for the account of Purchaser; provided that if this Agreement is terminated under Section 11.1(c), then the Parties shall have no additional remedies against one another as a result of such termination, and Seller shall be free to enjoy immediately all rights of ownership of the Assets and to sell, transfer, encumber, or otherwise dispose of the Assets to any Person without any restriction under this Agreement.

(e)Promptly, but in no event later than three (3) Business Days after the Termination Date, the Purchaser and Seller shall execute and deliver to the Escrow Agent joint written instructions instructing the Escrow Agent to disburse via wire transfer of immediately available funds the entirety of the Deposit to the Party entitled to receive the Deposit as provided in this Section 11.2.

(f)Each Party acknowledges that as express consideration for the Parties entering into this Agreement and such Party’s representations, warranties and covenants set forth herein, each Party covenants and agrees that solely with respect to each Parties’ rights under Section 11.2(b) and Section 11.2(c) (i) each Party would be irreparably harmed by any breaches by the other Party of its obligations to consummate the transactions hereunder as and when required by such Party hereunder, (ii) monetary damages would not be a sufficient remedy for any violation of the terms of this Agreement with respect to each Parties’ rights under Section 11.2(b) and Section 11.2(c), (iii) the other Party shall be entitled to equitable relief, including injunction (without the posting of any bond and without proof of actual damages) and specific performance, in the event of any breach of the provisions of this Agreement with respect to each Parties’ rights under Section 11.2(b) and Section 11.2(c), in addition to all other remedies available at law or in equity, including monetary damages, and (iv) neither Party, nor its representatives, shall oppose the granting of specific performance or any such relief as a remedy with respect to each Parties’ rights under Section 11.2(b) and Section 11.2(c).

-85-

(g)In the event (i) this Agreement is terminated under Section 11.1(b) and (ii) Purchaser has asserted in writing that the condition set forth in Section 8.2(d) has not been satisfied on or before the Initial Outside Date, then for the sole purpose of determining which Party is entitled to receive the Deposit under Section 11.2(c) or Section 11.2(d) as to whether the condition in Section 8.2(d) or Section 8.1(d) has been satisfied, (A) all unresolved disputes with respect to any Disputed Defect Matters, or Casualty Losses, mutatis mutandis, may be submitted to an expert arbitration in accordance with and subject to the terms of Section 3.2(i), mutatis mutandis, and (B) in such case, the Parties shall select a Title Referee or Environmental Referee within five (5) Business Days of the termination of this Agreement, each Party shall submit such Party’s position to the Title Referee or Environmental Referee, as applicable, within ten (10) Business Days of the termination of this Agreement, and each Party shall instruct the applicable Defect Referee, as applicable, to deliver its determination of the existence and/or Defect Amounts attributable to all Disputed Defect Matters or disputed Casualty Loss amounts, as applicable, within ten (10) Business Days after the appointment of such Person.

(a) Notwithstanding anything to the contrary contained in this Agreement, from and after Closing, Purchaser’s and Purchaser Group’s sole and exclusive remedy against any member of the Seller Group with respect to the negotiation, performance and consummation of the transactions contemplated hereunder, any breach of the representations, warranties, covenants and agreements of any member of the Seller Group contained herein, the affirmations of such representations, warranties, covenants and agreements contained in the certificate delivered by Seller at Closing pursuant to Section 9.2(f) or contained in any other Transaction Document delivered hereunder by or on behalf of any member of the Seller Group are (i) the rights to indemnity from Seller set forth in Section 12.3 with respect to the Specified Litigation, as limited by the terms of this Article 12, (ii) the rights to proceeds of the R&W Insurance Policy; and (iii) the right to specific performance for the breach or failure of the other Party to perform any covenants required to be performed after Closing pursuant to Section 12.4(c).

Section 12.6Indemnification Actions. All claims for indemnification under Article 12 shall be asserted and resolved as follows:

(a)For purposes of this Article 12, the term “Indemnifying Party” when used in connection with particular Damages means (i) Seller in the event any member of the Purchaser Group is entitled to indemnity from Seller under Section 12.3 and (ii) Purchaser in the event any member of the Seller Group is entitled to indemnification under this Agreement. For purposes of this Article 12, the term “Indemnified Person” when used in connection with particular Damages means (i) Purchaser in the event any member of the Purchaser Group is entitled to indemnity from Seller under Section 12.3 and (ii) Seller in the event any member of the Seller Group is entitled to indemnification under this Agreement.

-88-

(b) To make a claim for indemnification, defense or reimbursement under this Article 12, an Indemnified Person shall notify the Indemnifying Party of its claim, including the specific details (including supporting documentation in such Indemnified Person’s possession or control of the alleged Damages and such Indemnified Person’s good faith estimate of the applicable claim) of and specific basis under this Agreement for its claim (the “Claim Notice”).

(c)In the event that any claim for indemnification set forth in any Claim Notice is based upon a claim by a Third Party against the Indemnified Person (a “Third Party Claim”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim in such Indemnified Person’s possession or control; provided that the failure of any Indemnified Person to give notice of any Third Party Claim as provided in this Section 12.6 shall not relieve the Indemnifying Party of its obligations under this Article 12 except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise prejudices the Indemnifying Party’s ability to defend against the Third Party Claim. In the event that the claim for indemnification is based upon an alleged inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was allegedly inaccurate or breached.

(d)Subject to Section 12.6(f), in the case of a claim for indemnification based upon any Third Party Claim, the Indemnifying Party shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies (i) in the case of Seller, Purchaser’s right to indemnity from Seller in respect of such Third Party Claim as provided in this Article 12 or (ii) in the case of Purchaser, its obligation to defend the Indemnified Person against such Third Party Claim under this Agreement. The Indemnified Person is authorized, prior to and during such thirty (30) day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party. If the Indemnifying Party fails to notify the Indemnified Person within such thirty (30) day period regarding whether the Indemnifying Party admits or denies (A) in the case of Seller, Purchaser’s right to indemnity from Seller in respect of such Third Party Claim as provided in this Article 12 or (B) in the case of Purchaser, its obligation to defend the Indemnified Person against such Third Party Claim under this Agreement, then until such date as the Indemnifying Party admits or it is finally determined by a non-appealable judgment that such right or obligation exists, the Indemnified Person may file any motion, answer or other pleading, settle any Third Party Claim or take any other action that the Indemnified Person deems necessary or appropriate to protect its interest, regardless of whether the Indemnifying Party is prejudiced or adversely impacted by any such actions.

-89-

(e) If (x) Seller admits Purchaser’s right to indemnity from Seller in respect of such Third Party Claim as provided in this Article 12 or (y) Purchaser admits its obligation to defend the Indemnified Person against such Third Party Claim under this Agreement, as applicable, then the applicable Indemnifying Party shall have (i) the right and obligation to diligently prosecute and control the defense of such Third Party Claim, if Purchaser is the Indemnifying Party, at the sole cost and expense of Purchaser, and if Seller is the Indemnifying Party, at the sole cost and expense of Seller, and (ii) have full control of such defense and proceedings, including any compromise or settlement thereof unless the compromise or settlement includes the payment of any amount by, the performance of any obligation by, or the limitation of any right or benefit of, the Indemnified Person, in which event such settlement or compromise shall not be effective without the consent of the Indemnified Person, which shall not be unreasonably withheld or delayed. If requested by the Indemnifying Party, the Indemnified Person agrees at the cost and expense of the Indemnifying Party to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest; provided, however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person. The Indemnified Person may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 12.6(e), provided that the Indemnified Person may file initial pleadings as described in the last sentence of Section 12.6(d) if required by court or procedural rules to do so within the thirty (30) day period in Section 12.6(d). An Indemnifying Party shall not, without the written consent of the Indemnified Person, settle any Third Party Claim or consent to the entry of any judgment with respect thereto that (A) does not result in a final resolution of the Indemnified Person’s liability with respect to the Third Party Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person from all further liability in respect of such Third Party Claim) or (B) may materially and adversely affect the Indemnified Person (other than as a result of money damages covered by the indemnity).

(f) If (x) Seller does not admit Purchaser’s right to indemnity from Seller in respect of such Third Party Claim as provided in this Article 12 or admits such right but thereafter fails to diligently defend or settle the Third Party Claim or (y) Purchaser admits its obligation to defend the Indemnified Person against such Third Party Claim under this Agreement or admits its obligation but thereafter fails to diligently defend or settle the Third Party Claim, as applicable, then the Indemnified Person shall have the right, but not the obligation, to defend and control the defense against the Third Party Claim (if Purchaser is the Indemnifying Party, at the sole cost and expense of Purchaser, and if Seller is the Indemnifying Party, at the sole cost and expense of Seller, and in either case if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing, subject to the right of (x) Seller as the Indemnifying Party to admit Purchaser’s right to indemnity from Seller in respect of such Third Party Claim as provided in this Article 12 or (y) Purchaser as the Indemnifying Party to admit its obligation to defend the Indemnified Person against such Third Party Claim under this Agreement, as applicable, at any time prior to settlement or final determination thereof. If (x) Seller has not yet admitted Purchaser’s right to indemnity from Seller in respect of such Third Party Claim as provided in this Article 12 or (y) Purchaser has not yet admitted its obligation to defend the Indemnified Person against such Third Party Claim under this Agreement, as applicable, the Indemnified Person shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for ten (10) days following receipt of such notice to (i) (1) in the case of Seller, admit Purchaser’s right to indemnity from Seller in respect of such Third Party Claim as provided in this Article 12 or (2) in the case of Purchaser, admit its obligation to defend the Indemnified Person against such Third Party Claim under this Article 12, as applicable, and (ii) if such right or obligation is so admitted, assume the defense of the Third Party Claim, including the power to reject the proposed settlement. If the Indemnified Person settles any Third Party Claim over the objection of the Indemnifying Party after the Indemnifying Party has timely admitted such right or obligation for indemnification in writing and assumed the defense of the Third Party Claim, the Indemnified Person shall be deemed to have waived any right to indemnity with respect to the Third Party Claim.

-90-

(g)In the case of a claim for indemnification not based upon a Third Party Claim (a “Direct Claim”), such Direct Claim shall be asserted by giving the Indemnifying Party a reasonably prompt Claim Notice thereof, but in any event not later than thirty (30) days after the Indemnified Person becomes aware of the events that gave rise to such Direct Claim. Such Claim Notice by the Indemnified Person shall describe the Direct Claim in reasonable detail, shall include copies of all available material written evidence in such Indemnified Person’s possession or control thereof and shall indicate the estimated amount, if reasonably practicable, of Damages that have been or may be sustained by the Indemnified Person. The Indemnifying Party shall have sixty (60) days from its receipt of the Claim Notice to (i) cure the Damages complained of, (ii) (x) in the case of Seller, admit Purchaser’s right to indemnity from Seller in respect of such Direct Claim as provided in this Article 12 or (y) in the case of Purchaser, admit its obligation to defend the Indemnified Person against such Direct Claim under this Agreement and Section 13.13, or (iii) dispute the claim for such Damages. If the Indemnifying Party does not notify the Indemnified Person within such sixty (60) day period that it has cured the Damages or that it disputes the claim for such Damages, the Indemnifying Party shall be deemed to have disputed its obligation to defend the Indemnified Person against such Direct Claim under this Agreement.

(h)The Parties shall treat, for U.S. federal and applicable state and local income Tax purposes, any amounts paid or received under this Article 12 as an adjustment to the Adjusted Purchase Price, unless otherwise required by applicable Laws.

Section 12.7  Express Negligence/Conspicuous Manner. WITH RESPECT TO THIS AGREEMENT, BOTH PARTIES AGREE THAT THE PROVISIONS SET OUT IN THIS Article 12 AND ELSEWHERE IN THIS AGREEMENT COMPLY WITH THE REQUIREMENT, KNOWN AS THE EXPRESS NEGLIGENCE RULE, TO EXPRESSLY STATE IN A CONSPICUOUS MANNER TO AFFORD FAIR AND ADEQUATE NOTICE THAT THIS AGREEMENT HAS PROVISIONS REQUIRING PURCHASER TO BE RESPONSIBLE FOR THE NEGLIGENCE (whether gross, sole, joint, active, passive, comparative or concurrent), STRICT LIABILITY, OR OTHER FAULT OF MEMBERS OF THE SELLER GROUP. PURCHASER REPRESENTS TO THE SELLER group (A) THAT PURCHASER HAS CONSULTED AN ATTORNEY CONCERNING THIS AGREEMENT OR, IF IT HAS NOT CONSULTED AN ATTORNEY, THAT PURCHASER WAS PROVIDED THE OPPORTUNITY AND HAD THE ABILITY TO SO CONSULT, BUT MADE AN INFORMED DECISION NOT TO DO SO AND (B) THAT PURCHASER FULLY UNDERSTANDS ITS OBLIGATIONS UNDER THIS AGREEMENT.

The rights and obligations of each Party shall be determined pursuant to this Agreement. Seller and Purchaser have each had the opportunity to exercise business discretion in relation to the negotiation of the details and terms of the transaction contemplated hereby. This Agreement is the result of arm’s length negotiations from equal bargaining positions. It is the intention of the Parties that every covenant, term and provision of this Agreement shall be construed simply according to its fair meaning and not strictly for or against any Party (notwithstanding any rule of law requiring an agreement to be strictly construed against the drafting Party) and no consideration shall be given or presumption made, on the basis of who drafted this Agreement or any particular provision thereof, it being understood that the Parties to this Agreement are sophisticated and have had adequate opportunity and means to exercise business discretion in relation to the negotiation of the details of the transaction contemplated hereby and retain counsel to represent their interests and to otherwise negotiate the provisions of this Agreement.

Section 13.5 Waivers. Any failure by any Party to comply with any of its obligations, agreements or conditions herein contained may be waived by the Party to whom such compliance is owed by the application of the express terms hereof by an instrument signed by the Party to whom compliance is owed and expressly identified as a waiver, but not in any other manner. No course of dealing on the part of any Party or its respective officers, employees, agents, or representatives and no failure by any Party to exercise any of its rights under this Agreement shall, in each case, operate as a waiver thereof or affect in any way the right of such Party at a later time to enforce the performance of such provision. Except as otherwise expressly provided herein, no waiver of, or consent to a change in or modification of, any of the provisions of this Agreement shall be deemed or shall constitute a waiver of, or consent to a change in or modification of, other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided herein. The rights of each Party under this Agreement shall be cumulative and the exercise or partial exercise of any such right shall not preclude the exercise by such Party of any other right.

Section 13.6 Severability. It is the intent of the Parties that the provisions contained in this Agreement shall be severable and should any terms or provisions, in whole or in part, be held invalid, illegal or incapable of being enforced as a matter of law, such holding shall not affect the other portions of this Agreement, and such portions that are not invalid shall be given effect without the invalid portion. Upon such determination that any term or provision is invalid, illegal or incapable of being enforced, the Parties 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 13.7 Assignment. No Party shall assign or otherwise transfer all or any part of this Agreement, nor shall any Party delegate any of its rights or duties hereunder, without the prior written consent of the other Party and any transfer or delegation made without such consent shall be null and void; provided, however that prior to Closing, Purchaser may assign all or any portion of its rights or obligations under this Agreement to an Affiliate of Purchaser (provided that Purchaser and such Affiliate shall be jointly and severally liable for all obligations of Purchaser under this Agreement) without Seller’s prior written consent. Unless expressly agreed to in writing by the Parties, no permitted assignment of any Party’s rights or duties that is subject to the consent of the other Party shall relieve or release the assigning Party from the performance of such Party’s rights or obligations hereunder and such assigning Party shall be fully liable to the other Party for the performance of all such rights and duties. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective permitted successors and assigns.

Section 13.8 Entire Agreement. This Agreement and the other Transaction Documents constitute the entire agreement between the Parties pertaining to the subject matter hereof, and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties pertaining to the subject matter hereof. IN THE EVENT OF A CONFLICT BETWEEN THE TERMS AND PROVISIONS OF THIS AGREEMENT AND THE TERMS AND PROVISIONS OF ANY SCHEDULE OR EXHIBIT HERETO, THE TERMS AND PROVISIONS OF THIS AGREEMENT SHALL GOVERN AND CONTROL; PROVIDED, HOWEVER THAT THE INCLUSION IN ANY OF THE SCHEDULES AND EXHIBITS HERETO OF TERMS AND PROVISIONS NOT ADDRESSED IN THIS AGREEMENT SHALL NOT BE DEEMED A CONFLICT, AND ALL SUCH ADDITIONAL PROVISIONS SHALL BE GIVEN FULL FORCE AND EFFECT, SUBJECT TO THE PROVISIONS OF THIS Section 13.8.

Each Non-Recourse Person is expressly intended as a Third Party beneficiary of this Section 13.11.

Section 13.12 Limitation on Damages. Notwithstanding anything to the contrary contained herein, no Person shall be entitled to punitive damages in connection with this Agreement and the transactions contemplated hereby and each of Purchaser and Seller, for itself and on behalf of their respective members of the Purchaser Group and Seller Group, respectively, hereby expressly waives any right to punitive damages in connection with this Agreement and the transactions contemplated hereby, other than punitive damages suffered by any Third Party for which responsibility is allocated among the Parties under the terms hereof.

Purchaser certifies that it is not a “consumer” within the meaning of the Texas Deceptive Trade Practices Consumer Protection Act, Subchapter E of Chapter 17, Sections 17.41, et seq., of the Texas Business and Commerce Code, (as amended, the “DTPA”). Purchaser covenants, for itself and for and on behalf of any successor or assignee, that if the DTPA is applicable to this Agreement, (a) Purchaser is a “business consumer” as that term is defined in the DTPA, (b) AFTER CONSULTATION WITH ATTORNEYS OF PURCHASER’S OWN SELECTION, PURCHASER HEREBY VOLUNTARILY WAIVES AND RELEASES ALL OF PURCHASER’S RIGHTS AND REMEDIES UNDER THE DTPA AS APPLICABLE TO SELLER AND SELLER’S SUCCESSORS AND ASSIGNS AND (c) PURCHASER SHALL DEFEND AND INDEMNIFY THE SELLER GROUP FROM AND AGAINST ANY AND ALL CLAIMS OF OR BY ANY MEMBER OF THE PURCHASER GROUP OR ANY OF THEIR SUCCESSORS AND ASSIGNS OR ANY OF ITS OR THEIR AFFILIATES BASED IN WHOLE OR IN PART ON THE DTPA ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT.

Section 13.17 Debt Financing Sources. Notwithstanding anything to the contrary herein, each of the parties on behalf of itself and each of its Affiliates hereby: (a) agrees that any legal action (whether in Law or in equity, whether in Contract or in tort or otherwise), involving any Debt Financing Source Related Party, arising out of or relating to this Agreement, any Debt Financing or any of the transactions contemplated hereby or thereby or the performance of any services thereunder, shall be subject to the exclusive jurisdiction of the courts of the State of Texas and the federal courts of the Southern District of Texas, in each case located in Harris County, and any appellate court from any thereof, (each such court, the “Subject Courts”) and each party irrevocably submits itself and its property with respect to any such legal action to the exclusive jurisdiction of such Subject Courts and agrees that any such dispute shall be governed by, and construed in accordance with, the Laws of the State of New York, except as otherwise set forth in any commitment letter in respect of such Debt Financing with respect to (i) the determination of the accuracy of any “specified acquisition agreement representation” (as such term or similar term is defined in such commitment letter) and whether as a result of any inaccuracy thereof Purchaser or any of its Affiliates has the right to terminate its or their obligations hereunder pursuant to Article 11 or decline to consummate the Closing as a result thereof pursuant to Section 8.2 and (iii) the determination of whether the Closing has been consummated in all material respects in accordance with the terms hereof, which shall in each case be governed by and construed in accordance with the Laws of the State of Texas, without giving effect to any choice or conflict of Law provision or rule that would cause the application of Laws of any other jurisdiction, (b) agrees not to bring or support or permit any of its Affiliates to bring or support any legal action (including any action, cause of action, claim, cross-claim or third party claim of any kind or description, whether in Law or in equity, whether in Contract or in tort or otherwise), against any Debt Financing Source Related Party in any way arising out of or relating to this Agreement, any Debt Financing or any of the transactions contemplated hereby or thereby or the performance of any services thereunder in any forum other than any Subject Court, (c) irrevocably waives, to the fullest extent that it may effectively do so, the defense of an inconvenient forum to the maintenance of such legal action in any such Subject Court, (d) knowingly, intentionally and voluntarily waives to the fullest extent permitted by applicable Law trial by jury in any legal action brought against any Debt Financing Source Related Party in any way arising out of or relating to this Agreement, any Debt Financing or any of the transactions contemplated hereby or thereby or the performance of any services thereunder, (e) agrees that no Debt Financing Source Related Party will have any liability to any of the Seller Entities or their respective shareholders or Affiliates relating to or arising out of this Agreement, any Debt Financing or any of the transactions contemplated hereby or thereby or the performance of any services thereunder and that none of the Seller Entities or any of their respective Affiliates or shareholders shall bring or support any legal action (including any action, cause of action, claim, cross-claim or third party claim of any kind or description, whether in Law or in equity, whether in Contract or in tort or otherwise), against any Debt Financing Source Related Source relating to or in any way arising out of this Agreement, any Debt Financing or any of the transactions contemplated hereby or thereby or the performance of any services thereunder, (f) waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any legal action involving any Debt Financing Source Related Party or the transactions contemplated hereby, any claim that it is not personally subject to the jurisdiction of the Subject Courts as described herein for any reason, and (g) agrees (i) that any Debt Financing Source Related Parties are express third party beneficiaries of, and may enforce, any of the provisions in this Section 13.17 (or the definitions of any terms used in this Section 13.17) and (ii) to the extent any amendments to any provision of this Section 13.17 (or, solely as they relate to such Section, the definitions of any terms used in this Section 13.17) are materially adverse to any Debt Financing Source Related Party, such provisions shall not be amended without the prior written consent of each applicable Debt Financing Source.

Disclosure ScheduleS

Neither these Schedules nor any disclosure made in or by virtue of them constitutes or implies any representation, warranty, or covenant by Seller not expressly set out in the Agreement, and neither these Schedules nor any such disclosure has the effect of, or may be construed as, adding to, broadening, deleting from or revising the scope of any of the representations, warranties, or covenants of Seller in the Agreement. Any item or matter disclosed or listed on any particular Schedule is deemed to be disclosed or listed on any other Schedules to the extent it is reasonably apparent that such item relates or is applicable to, or is (or would be) properly disclosed under, such other Schedule or the section of the Agreement to which such other Schedule corresponds, notwithstanding the fact that the Schedules are arranged to correspond to the sections of the Agreement, that a particular section of the Agreement makes reference to a particular Schedule, or that a particular representation, warranty or covenant in the Agreement may not make reference to a Schedule. Matters reflected in these Schedules are not necessarily limited to matters required by the Agreement to be reflected in these Schedules. The fact that any item of information is contained herein is not an admission of liability under any applicable Law, and does not mean that such information is required to be disclosed in or by the Agreement, or that such information is material, but rather is intended only to qualify the representations, warranties and covenants in the Agreement and to set forth other information required by the Agreement. Neither the specification of any dollar amount in any representation, warranty or covenant contained in the Agreement nor the inclusion of any specific item in these Schedules is intended to imply that such amount, or a higher or lower amount, or the item so included, or any other item, is or is not material, and no Person shall use the setting forth of any such amount or the inclusion of any such item in any dispute or controversy between or among the parties to the Agreement as to whether any obligation, item or matter not described herein or included in these Schedules is or is not material for purposes of the Agreement. The information set forth on the Schedules shall not be used as a basis for interpreting the terms “material,” “materially,” “materiality,” “Material Adverse Effect,” or any similar qualification in the Agreement. Neither the specification of any item or matter in any representation, warranty or covenant contained in the Agreement nor the inclusion of any specific item in these Schedules is intended to imply that such item or matter, or another item or matter, is or is not in the ordinary course of business, and no Person shall use the setting forth or the inclusion of any such item or matter in any dispute or controversy between or among the parties to the Agreement as to whether any obligation, item or matter described or not described herein or included or not included in these Schedules is or is not in the ordinary course of business for purposes of the Agreement.

Headings have been inserted in these Schedules for reference only and do not amend the descriptions of the disclosed items set forth in the Agreement. Where a reference is made to a section or exhibit, such reference shall be to a section of or exhibit to the Agreement unless otherwise indicated. Whenever the words “include,” “includes,” or “including” are used in these Schedules, they shall be deemed to be followed by the words “without limitation,” whether or not they are in fact followed by those words or words of like import.
