If Sellers’ Representative fails to timely deliver a Dispute Notice to Purchaser containing changes Sellers’ Representative proposes to be made to a final settlement statement, such final settlement statement as delivered by Purchaser will be deemed to be correct and mutually agreed upon by the Parties and will be final and binding on the Parties (excluding any adjustments with respect to disputed alleged Defects, any Title Defects subject to post-Closing cure (which amounts shall be included in the Defect Deposit, if applicable), and any disputes with respect to alleged Title Benefits and Additional Leases for which amounts are included in the Additional Lease Deposit, each of which shall be exclusively addressed and resolved exclusively under Section 3.2(i)) and not subject to further audit or arbitration. The Parties shall undertake to agree on the final statement of the Adjusted Purchase Price attributable to each Seller no later than ten (10) days following Purchaser’s receipt of Sellers’ Representative’s Dispute Notice (if any) delivered hereunder. In the event that the Parties cannot reach agreement as to any final settlement statement of the Adjusted Purchase Price or portion thereof (but excluding any adjustments with respect to disputed alleged Defects, any Title Defects subject to post-Closing cure (which amounts shall be included in the Defect Deposit, if applicable), and any disputes with respect to alleged Title Benefits and Additional Leases for which amounts are included in the Additional Lease Deposit, each of which shall be exclusively addressed and resolved exclusively under Section 3.2(i)) within such period of time, then either Party may (upon not less than one (1) Business Day’s prior written notice to the other Party) refer the items of adjustment which are in dispute or the interpretation or effect of this Section 2.7(b) to a nationally recognized independent accounting firm or consulting firm mutually acceptable to both Sellers’ Representative and Purchaser (the “Accounting Referee”) for review and final determination by arbitration. The

59

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 2.7(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 shall be made, based on the materials submitted to the Accounting Referee as described above and not by independent review, within fifteen (15) days after submission of the matters in dispute and shall be final and binding on all Parties, without right of appeal, and shall constitute an arbitral award upon which a judgement may be entered in any court having jurisdiction thereof. In determining the amount of any adjustment to the Adjusted Purchase Price (but excluding any adjustments with respect to disputed alleged Defects, any Title Defects subject to post-Closing cure (which amounts shall be included in the Defect Deposit, if applicable), and any disputes with respect to alleged Title Benefits and Additional Leases for which amounts are included in the Additional Lease Deposit, each of which shall be exclusively addressed and resolved exclusively under Section 3.2(i)), the Accounting Referee shall be bound by the terms of this Agreement (including Section 2.4 and Section 2.5) and may not increase the Adjusted Purchase Price more than the increase proposed by Sellers’ Representative nor decrease the Adjusted Purchase Price more than the decrease proposed by Purchaser, as applicable. The Accounting Referee shall act as an expert for the limited purpose of determining the specific disputed aspects of Adjusted Purchase Price adjustments submitted by any Party and may not award damages, interest (except to the extent expressly provided for in this Section 2.7), or penalties to any Party with respect to any matter. Each Seller and Purchaser shall each bear its own legal fees and other costs of presenting its case. Sellers shall collectively bear one-half and Purchaser shall bear one-half of the fees, costs and expenses of the Accounting Referee.

(c) Sellers’ Representative and each Seller shall promptly assist Purchaser in preparation of the final settlement statement of the Adjusted Purchase Price under Section 2.7(b) by furnishing invoices, receipts, reasonable access to personnel and such other assistance as may be reasonably requested by Purchaser to facilitate such process post-Closing. Following the Closing and until the Adjusted Purchase Price is finalized, Purchaser and the Subject Companies shall promptly (i) make available to Sellers’ Representative and each Seller all reasonably requested Records, including all invoices and receipts, and (ii) provide reasonable access to Purchaser and its Affiliate’s personnel during normal business hours, in each case, to the extent reasonably necessary for Sellers’ Representative and each Seller to review, audit and provide comments to the proposed final settlement statement(s) proposed by Purchaser.

(d) Within five (5) Business Days after the earlier of (x) the expiration of the Dispute Period without delivery of any written report or objections by Sellers’ Representative or (y) if Sellers’ Representative delivers any such report or objection, the date on which the Parties or the Accounting Referee finally determine in writing the Adjusted Purchase Price (but excluding any adjustments with respect to disputed alleged Defects, any Title Defects subject to post-Closing cure (which amounts shall be included in the Defect Deposit, if applicable), and disputed alleged Title Benefits and Additional Leases for which amounts are included in the Additional Lease Deposit, each of which shall be exclusively addressed and resolved exclusively under Section 3.2(i)):

60

(i) if the Adjusted Purchase Price, as finally determined pursuant to this Section 2.7, equals or exceeds the Closing Adjusted Purchase Price (in each case excluding any adjustments with respect to alleged Defects subject to dispute at Closing for which amounts are included in the Defect Deposit and alleged Title Benefits and Additional Leases subject to dispute at Closing for which amounts are included in the Additional Lease Deposit, each of which shall be exclusively addressed and resolved exclusively under Section 3.2(i)) then (A) Purchaser shall pay to the Persons as directed by Sellers’ Representative by wire transfer of immediately available funds to an account(s) designated by Sellers’ Representative in writing an amount in cash equal to such excess, if any, and (B) Sellers’ Representative and Purchaser shall execute and deliver joint written instructions to the Escrow Agent instructing the Escrow Agent to disburse the entirety of the Adjustment Deposit to the Person(s) and to the accounts designated by Sellers’ Representative; or

(ii) if the Adjusted Purchase Price as finally determined pursuant to this Section 2.7 is less than the Closing Adjusted Purchase Price (in each case, disregarding any adjustments with respect to disputed alleged Defects, any Title Defects subject to post-Closing for which amounts shall be included in the Defect Deposit, if applicable), and any disputes with respect to alleged Title Benefits and Additional Leases subject to dispute at Closing for which amounts are included in the Additional Lease Deposit, each of which shall be exclusively addressed and resolved exclusively under Section 3.2(i), then promptly (and in any event within three (3) Business Days following the final determination of the Adjusted Purchase Price), Sellers’ Representative and Purchaser shall execute and deliver joint written instructions to the Escrow Agent instructing the Escrow Agent to disburse from the Adjustment Deposit (A) to Purchaser an amount in cash equal to the amount of such excess and (B) to the Person(s) and to the accounts designated by Sellers’ Representative, the remainder of the Adjustment Deposit (if any) after such payment to the Purchaser. For the avoidance of doubt, any amounts payable to the Purchaser pursuant to the foregoing sentence shall be satisfied exclusively out of the Adjustment Deposit.

(e) All cash payments made or to be made under this Agreement to or at the direction of any Seller shall be made by electronic transfer of immediately available funds to such bank and account as may be specified by Sellers’ Representative in writing in accordance with this Agreement.

(f) All adjustments and payments made pursuant to this Article 2 shall be without duplication of any other amounts paid, credited, debited, or received under this Agreement.

Section 2.8 Tax Treatment; Allocation of Purchase Price for Tax Purposes. The Parties agree that the sale of the Subject Securities pursuant to Section 2.1 will be treated for U.S. federal and applicable state and local income tax purposes as a taxable sale of all of the Assets by the Sellers to Purchaser. No Party or any Affiliate thereof shall take a position inconsistent with the preceding sentence for any purpose unless otherwise required pursuant to a “determination” within

61

the meaning of Section 1313(a) of the Code or corresponding provision of applicable U.S. state or local Law. Each of Sellers’ Representative and Purchaser shall use commercially reasonable efforts to agree upon an allocation of the Adjusted Purchase Price and any other items properly treated as consideration for U.S. federal income tax purposes with respect to the Assets sold by each Seller 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 (and in a manner consistent with the Allocated Values and the applicable Seller’s respective percentage of the Adjusted Purchase Price) thereunder within thirty (30) days after the Cut-Off Date (collectively, the “Allocation”). If Sellers’ Representative and Purchaser reach an agreement with respect to the Allocation, (a) Sellers’ Representative and Purchaser shall use commercially reasonable efforts to update the Allocation in a manner consistent with Section 1060 of the Code following any adjustment to the purchase consideration for Tax purposes pursuant to this Agreement, and (b) Sellers and Purchaser Parties shall, and shall cause their Affiliates to, report consistently with the Allocation, as adjusted, on all Tax Returns, including IRS Form 8594, which Sellers and Purchaser Parties shall timely file with the IRS, as applicable, and neither Sellers nor Purchaser shall take any position on any Tax Return that is inconsistent with the Allocation, as adjusted, unless otherwise required by applicable Law; provided, however, that (i) to the extent Sellers’ Representative and Purchaser Parties 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 (ii) 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 to the Sellers such amounts as are required to be withheld and paid over to the applicable Governmental Authority under the Code, or any applicable provision of Tax Law; provided, that other than with respect to withholding Taxes owed as a result of the failure of any Seller to deliver one of the forms described in Section 10.2(d), Purchaser will, prior to any deduction or withholding, use commercially reasonable efforts to notify the applicable Seller of any anticipated withholding, and reasonably cooperate with such Seller to minimize the amount of any applicable withholding to such Seller. To the extent that amounts are so withheld and paid over to the applicable Governmental Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to Seller in respect of which such deduction or withholding was made.

Section 2.10 1031 Exchange. The Sellers reserve the right, at or prior to Closing, to assign their rights under this Agreement with respect to all or a portion of the consideration payable pursuant to this Agreement, and that portion of the Assets associated therewith (the “1031 Assets”), to a Qualified Intermediary (as that term is defined in Section 1.1031(k)-1(g)(4) of the Treasury Regulations) (the “QI”) or to an Exchange Accommodation Titleholder (as that term is defined in Internal Revenue Service Revenue Procedure 2000-37) (the “EAT”) to accomplish this Transaction, in whole or in part, as a like-kind exchange in compliance with Section 1031 of the Code (a “Like-Kind Exchange”). The Purchaser Parties hereby (a) consent to any Seller’s assignment of its rights in this Agreement with respect to the 1031 Assets; provided that any such assignment will not result in a distribution of any Parent Common Equity to a Canadian resident or a person otherwise domiciled in Canada, and (b) if such an assignment is made, Purchaser shall pay all or a portion of the consideration payable pursuant to this Agreement into a qualified trust

62

or escrow account at Closing as directed in writing by Sellers’ Representative and the QI or EAT, as applicable. Purchaser likewise reserves the right, at or prior to Closing, to assign all or a portion of its rights in this Agreement to a QI or to an EAT in connection with effecting any Like-Kind Exchange. The Sellers hereby consent to Purchaser’s assignment of all or a portion of its rights in this Agreement to an EAT or QI, as applicable, at Closing, as directed in writing by Purchaser and the EAT or QI, as applicable. The Purchaser Parties and the Sellers acknowledge and agree that (i) the Closing shall not be delayed or affected by reason of a Like-Kind Exchange, (ii) a whole or partial assignment of this Agreement to a QI or EAT shall not release any Party from, or modify, any of their respective liabilities and obligations (including indemnity obligations to each other) under this Agreement, (iii) no Party makes any representations as to any particular Tax treatment that may be afforded to any other Party by reason of such assignment or any other actions taken in connection with any Like-Kind Exchange and (iv) in the event either Party assigns its rights under this Agreement pursuant to this Section 2.10, then such Party agrees to notify the other Party in writing of such assignment at or before the Closing. No Party shall be obligated to pay any additional costs or incur any additional obligations as a result of any Like-Kind Exchange effected by the other Party, and each Party electing to treat the Transaction as a Like-Kind Exchange shall be obligated to defend, hold harmless, and indemnify the other Party from and against all Damages, if any, resulting from such Like-Kind Exchange. No Party, by its consent to a Like-Kind Exchange, shall be responsible in any way for another Party’s compliance with such Like-Kind Exchange.

ARTICLE 3

TITLE AND ENVIRONMENTAL MATTERS

Section 3.1 Title and Environmental Matters. Purchaser hereby acknowledges and agrees that, without limitation of Sellers’ representations and warranties set forth in Article 4 or in Article 5, prior to Closing, this Article 3, the conditions to Closing set forth in Article 11 and the rights and remedies set forth in 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 any Subject Company Group, Subject Company 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 or obligation with respect to any Subject Company Group, Subject Company and/or the Assets.

Section 3.2 Defects; Adjustments.

(a) Notice of Defects. As a condition to Purchaser asserting any claim with respect to any alleged Defect pursuant to this Article 3, Purchaser must deliver to Sellers’ Representative a valid Notice or Notices (each a “Defect Notice”) with respect to such alleged Defect on or before 5:00 p.m. Central Time on the date that is fifty-five (55) days after the Execution Date (the “Defect Deadline”); provided that Purchaser shall use commercially reasonable efforts to provide to Sellers’ Representative weekly written updates no later than 5:00 p.m. Central Time on each Friday between the Execution Date and the Defect Deadline (which notices may be preliminary in nature and 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 notice with respect to any Defect shall not prejudice or restrict in any respect Purchaser’s right to subsequently assert such Defect in a Defect Notice on or before the Defect Deadline, nor shall such failure be deemed a breach of this Agreement. In order to be a valid Defect Notice as to an alleged Defect, each such Notice shall be in writing and must include the following:

(i) a description of the alleged Defect;

63

(ii) a description of the Asset subject to such alleged Defect;

(iii) the Allocated Value of each Asset subject to the alleged Defect (if applicable);

(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 Defect; and

(vi) with respect to any alleged Environmental Defect, if applicable, reference to the applicable Environmental Laws, if known, that have been violated or that require Remediation with respect to the applicable Assets as of the Effective Time.

SUBJECT TO, AND WITHOUT LIMITATION OF, PURCHASER’S RIGHTS UNDER THE R&W INSURANCE POLICY (AND WITHOUT LIMITATION OF SELLERS’ REPRESENTATIONS AND WARRANTIES SET FORTH IN ARTICLE 4 OR IN ARTICLE 5, THE CONDITIONS TO CLOSING SET FORTH IN ARTICLE 11 AND THE RIGHTS AND REMEDIES SET FORTH IN SET FORTH IN ARTICLE 12), AND ABSENT FRAUD, EACH PURCHASER PARTY 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 SELLERS’ REPRESENTATIVE HAS NOT RECEIVED ON OR BEFORE THE DEFECT DEADLINE A DEFECT NOTICE THAT SATISFIES EACH OF THE CONDITIONS AND REQUIREMENTS SET FORTH IN THIS SECTION 3.2(a) (OR WITH RESPECT TO SECTION 3.2(A)(I), SECTION 3.2(A)(V) AND SECTION 3.2(A)(VI), IN ALL MATERIAL RESPECTS).

(b) Notice of Title Benefits. As a condition to Sellers asserting any claim with respect to any alleged Title Benefit, should Sellers discover any Title Benefit at any time on or prior to the Defect Deadline, Sellers 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) a description of the DSU or Well subject to such alleged Title Benefit;

64

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

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

(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.

SELLERS 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 SELLERS’ REPRESENTATIVE HAS NOT SENT TO PURCHASER ON OR BEFORE THE DEFECT DEADLINE A VALID NOTICE THAT SATISFIES EACH OF THE CONDITIONS AND REQUIREMENTS SET FORTH IN THIS SECTION 3.2(b) (OR WITH RESPECT TO SECTION 3.2(B)(I) AND SECTION 3.2(B)(V), IN ALL MATERIAL RESPECTS).

(c) Option to Cure Defects. Sellers shall have the right, but not the obligation to attempt, at Sellers’ sole cost, to cure or remove, on or prior to the applicable Cure Deadline, any Defects asserted in a valid Defect Notice; provided that, if Sellers elect to cure any Title Defects after Closing, then Sellers shall notify Purchaser of its election prior to Closing. Alleged Defects shall be deemed to have been cured or removed if Sellers’ Representative 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, 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. If any asserted Defect is not cured, Remediated or removed, or if Sellers’ Representative 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. Any 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 such Seller’s right to dispute the validity, nature or value of, or cost to cure, such Defect.

(d) Defect Amounts. The diminution of value of the Assets attributable to any valid Defect that actually burdens, encumbers or affects a DSU or Well (the “Defect Amount”) shall be determined as follows:

(i) if Purchaser and Sellers’ Representative 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 shall be the amount necessary to be paid to remove the Title Defect from the Subject Company Group’s interest in the affected DSU or Well;

65

(iii) if a Title Defect as to the applicable Subject Formation affecting any Well or DSU represents a negative discrepancy between (A) the actual Net Revenue Interest for the applicable Subject Formation as to such Well or DSU and (B) the Net Revenue Interest percentage stated on the applicable Annex to Exhibit A-2 for such Subject Company Group with respect to such Subject Formation for such Well or the applicable Annex to Exhibit A-3 for such Subject Company Group with respect to such Subject Formation for such DSU, as applicable, and in such case there is a proportionate decrease 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 the applicable Annex to Exhibit A-2 for such Subject Company Group with respect to such Subject Formation for such Well or the applicable Annex to Exhibit A-3 for such Subject Company Group with respect to such Subject Formation for such DSU, as applicable, 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, as applicable multiplied by (2) a fraction, the numerator of which is (x) the remainder of (I) the “Net Revenue Interest” percentage stated on the applicable Annex to Exhibit A-2 for such Subject Company Group with respect to such Subject Formation for such Well or the applicable Annex to Exhibit A-3 for such Subject Company Group with respect to such Subject Formation for such DSU, as applicable, minus (II) the actual Net Revenue Interest for such Subject Company Group with respect to such Subject Formation as to such Well or DSU, as applicable, and the denominator of which is (y) the “Net Revenue Interest” percentage stated on the applicable Annex to Exhibit A-2 for such Subject Company Group with respect to such Subject Formation for such Well or the applicable Annex to Exhibit A-3 for such Subject Company Group with respect to such Subject Formation for such DSU, as applicable; provided that if the Title Defect does not affect the “Net Revenue Interest” percentage stated on the applicable Annex to Exhibit A-2 for such Subject Company Group with respect to such Subject Formation for such Well or the applicable Annex to Exhibit A-3 for such Subject Company Group with respect to such Subject Formation for such DSU, as applicable, 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 applicable Subject Formation as to a DSU or Well 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 Subject Formation for the DSU or Well so affected, the portion of the Subject Company Group’s interest in the applicable Subject Formation as to such DSU or Well 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 applicable Subject Formation as to such DSU or Well, the values placed upon the Title Defect by Purchaser, the estimated capital and operational costs and expenses (or reduction or increases thereof) attributable to the Subject Company Group’s Working Interest, and such other reasonable factors as are necessary to make a proper evaluation and determination of such value;

66

(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 allowed under Environmental Laws, may be the lowest-cost manner reasonably available and, where applicable, to the extent required by applicable Governmental Authorities; provided, however, such Defect Amount shall expressly exclude (A) the costs, fees and expenses of Purchaser’s and/or its Affiliate’s employees 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/amendment 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 such Asset (after giving effect to any applicable adjustments due to prior Defects), except with respect to Liens that are liquidated in amount with recourse to a Subject Company Group member or the Assets.

(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 Company Group with respect to such Subject Formation as to such Well or DSU and (B) the Net Revenue Interest percentage stated on the applicable Annex to Exhibit A-2 for such Subject Company Group with respect to such Subject Formation as to such Well or the applicable Annex to Exhibit A-3 for such Subject Company Group for such 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 the applicable Annex to Exhibit A-2 for such Subject Company Group with respect to such Subject Formation for such Well or the applicable Annex to Exhibit A-3 for such Subject Company Group with respect to such Subject Formation for such DSU, as applicable, then the Title Benefit Amount shall be equal to (1) the product of 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 (I) the actual Net Revenue Interest for such Subject Company Group with respect to such Subject Formation as to such Well or DSU minus (II) the Net Revenue Interest percentage stated

67

on the applicable Annex to Exhibit A-2 for such Subject Company Group with respect to such Subject Formation as to such Well or the applicable Annex to Exhibit A-3 for such Subject Company Group with respect to such Subject Formation as to such DSU, and the denominator of which is (y) the Net Revenue Interest percentage stated on the applicable Annex to Exhibit A-2 for such Subject Company Group with respect to such Subject Formation as to such Well or the applicable Annex to Exhibit A-3 for such Subject Company Group with respect to such Subject Formation for such DSU; provided that if the Title Benefit does not affect the Net Revenue Interest percentage stated on the applicable Annex to Exhibit A-2 for such Subject Company Group with respect to such Subject Formation as to such Well or the applicable Annex to Exhibit A-3 for such Subject Company Group with respect to such Subject Formation as to such DSU throughout its entire productive life, the Title Benefit Amount determined under this Section 3.2(e)(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 Subject Formation of the DSU or Well so affected, the portion of the Subject Company Group’s interest in the DSU or Well 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 DSU or Well, the values placed upon the Title Benefit by Purchaser and such other reasonable factors as are necessary to make a proper evaluation and determination of such value.

(f) Individual Threshold and Defect Deductibles; Title Benefit Amounts. 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 or Defects to the extent the Defect Amount for any valid individual Defect is less than the applicable Individual Threshold (it being agreed that the Individual Threshold represents a threshold and not a deductible);

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

(iii) except as provided in Section 3.2(f)(vi), with respect to all valid Environmental Defects where the Defect Amount thereof exceeds the applicable Individual Threshold, there shall be no adjustment to the Unadjusted Purchase Price under Section 3.2(g) with respect to any and all such Environmental Defects unless and until the aggregate Defect Amounts thereof that exceeds the applicable Individual Threshold also exceeds the Environmental Defect Deductible and then only to the extent such aggregate amount exceeds the Environmental Defect Deductible (it being the intention of the Parties that the Environmental Defect Deductible represents a deductible and not a threshold);

68

(iv) 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 shall be aggregated for purposes of calculating whether the Defect Amount associated with such Title Defect exceeds the applicable Individual Threshold;

(v) notwithstanding anything herein to the contrary, with respect to any Defect that is a Title Defect, the applicable Individual Threshold and the Title Defect Deductible shall not apply to any recourse under this Agreement (including any adjustments to the Unadjusted Purchase Price) in respect of a Special Warranty Defect; and

(vi) the Parties agree that for purposes of calculating the Individual 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 prepare and file the same type of plan (including spill, prevention, control, and countermeasure plans) or report), then the Defect Amounts associated with such Environmental Defect that is common across multiple Assets may be aggregated for purposes of meeting the Individual Threshold; provided, however, aggregation of Defect Amounts associated with Environmental Defects relating to any other conditions or liabilities arising under or relating to Environmental Laws may not be aggregated for purposes of meeting the Individual Threshold.

(g) Remedies for Defects. Subject to each Seller’s right to cure, Remediate, 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 (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 Section 3.2(f) and each Seller’s rights under Section 3.2(g)(iii), with respect to all uncured Title Defects for which the Defect Amount with respect thereto exceeds the applicable Individual Threshold, the Unadjusted Purchase Price shall be decreased by the sum of the aggregate Defect Amounts attributable to all such Title Defects, but only to the extent such aggregate sum with respect to Title Defects as to all Subject Company Groups exceeds the Title Defect Deductible (it being the intention of the Parties that the Title Defect Deductible constitutes a deductible and not a threshold);

(ii) subject to Section 3.2(f), with respect to all Environmental Defects that have not been Remediated and for which the Defect Amount with respect thereto exceeds the applicable Individual Threshold, the Unadjusted Purchase Price shall be decreased by the sum of the aggregate Defect Amounts attributable to all such Environmental Defects, but only to the extent such aggregate sum with respect to Environmental Defects as to all Subject Company Groups exceeds the Environmental Defect Deductible (it being the intention of the Parties that the Environmental Defect Deductible constitutes a deductible and not a threshold);

69

(iii) notwithstanding anything herein to the contrary, in lieu of the remedy for Title Defects set forth in Section 3.2(g)(i), if and only if the Defect Amount for a given Title Defect equals or exceeds one hundred percent (100%) of the Allocated Value of the applicable Well or DSU, Sellers’ Representative shall have the right, but not the obligation, to elect in writing delivered to Purchaser not later than two (2) Business Days prior to the Closing Date, to cause the applicable Subject Company Group to exclude any Oil and Gas Property subject to any alleged Title Defect (along with any other Assets reasonably necessary for the ownership or operation of such Assets) from the transactions contemplated hereunder and, in such event, (A) the Unadjusted Purchase Price with respect to the Subject Company Group 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 the applicable Annex to Exhibit A, (C) such Assets shall be deemed to constitute Excluded Assets and (D) at Closing, the applicable members of the Subject Company Group shall execute and deliver an assignment of such Excluded Assets in accordance with Section 10.2(j); and

(ii) If Sellers’ Representative and Purchaser are unable to agree on the interpretation and effect of this Article 3, the existence, cure, Remediation or amount of (A) any disputed Title Benefits, Title Benefit Amounts, Title Defects, or Defect Amounts associated with Title Defects, or (if applicable) any disputed Additional Lease Purchase Price for any Additional Leases as provided in Section 8.20 (each, a “Title Disputed Matter”) by the date one hundred (100) days after the Closing Date, or (B) any disputed Environmental Defects or Defect Amounts associated with Environmental Defects (each, an “Environmental Disputed Matter”, and together with the Title Disputed Matters, the “Disputed Defect Matters”) by the Closing Date, then, subject to Section 3.2(f) and Section 3.2(g), all such Disputed Defect Matters shall be exclusively and finally resolved pursuant to this Section 3.2(i). During the ten (10) Business Day period following (1) the date that is one hundred (100) days after the Closing Date, each of Sellers and Purchasers shall submit in writing its proposed resolution of each Title Disputed Matter to a title attorney that has at least ten (10) years’ experience in oil and gas titles in the State of Texas as selected by mutual agreement of Purchaser and Sellers’ Representative, or absent such agreement during such ten (10) Business Day period, by the Houston, Texas office of the AAA (the “Title Referee”) and (2) the Closing Date, each of Sellers and Purchasers shall submit in writing its proposed resolution of each Environmental Disputed Matter to a nationally recognized independent environmental consulting firm or environmental attorney experienced in resolving Environmental Liabilities mutually acceptable to Sellers’ Representative and Purchaser or, absent such agreement during such ten (10) Business Day period, by the Houston office of the AAA (the “Environmental Referee” and collectively with the Title Referee, each a “Defect Referee”). The Defect Referee shall not have worked as an employee, outside counsel or consultant, or in any other capacity, for any Party or any Affiliate of any Party during the ten (10) year period preceding the arbitration or have any financial interest in the dispute.

(iii) There shall be a single arbitration proceeding for all Title Disputed Matters properly submitted to the Title Referee and a single arbitration proceeding for all Environmental Disputed Matters properly submitted to the Environmental Referee. Each arbitration proceeding shall be held in Houston, Texas and shall be conducted in accordance with, but not under the auspices or jurisdiction of, the Commercial Arbitration Rules of the AAA, to the extent such rules do not conflict with the terms of this Section 3.2(i)(iii). The applicable Defect Referee’s determination shall be made within sixty (60) days after submission of the matters in dispute and shall be final and binding upon the Parties, without a right of appeal, and shall constitute an arbitral award upon which a judgement may be entered in any court having jurisdiction thereof. Neither Sellers nor Purchaser may have any ex parte communications with the applicable Defect Referee concerning the applicable Defect Referee’s determination of the applicable Disputed

71

Defect Matters. In making a determination, the applicable Defect Referee shall be bound by the rules set forth in this Article 3 or, if applicable, Section 8.20, and may consider such other matters as in the opinion of the applicable Defect Referee are necessary or helpful to make a determination; provided, however, in determining the existence or amount of any Defect or Defect Amount, neither Purchaser nor Seller may submit any evidence, records, materials, data or information that was not included either in a valid Defect Notice delivered to Sellers’ Representative by the Defect Deadline or in Sellers’ or Purchaser’s initial written submission to the applicable Defect Referee. Additionally, the applicable Defect Referee may consult with and engage any disinterested Third Party to advise the Defect Referee, including title attorneys, petroleum engineers and environmental consultants.

Notwithstanding anything herein to the contrary, the Defect Referee shall have exclusive, final and binding authority with respect to the scope of the Defect Referee’s authority regarding any Title Disputed Matter (with respect to the Title Referee) or Environmental Disputed Matter (with respect to the Environmental Referee), as applicable, and in no event shall any dispute as to the authority of the Defect Referee to determine any such disputes be subject to resolution or the provisions of Section 14.3. The applicable Defect Referee shall act as an expert for the limited purpose of determining the Disputed Defect Matters property submitted to such Defect Referee by any Party and may not award any damages, interest or penalties to any Party with respect to any matter. Sellers and Purchaser shall each bear their own respective legal fees and other costs of presenting its case. The fees, costs and expenses of the applicable Defect Referee shall be borne by Sellers, on the one hand, and by Purchaser, on the other hand, based upon the percentage that the amount not ultimately awarded to such Party by the applicable Defect Referee bears to the amount actually contested by such Party with respect to all applicable disputed matters.

(v) Promptly, and in any event within three (3) Business Days following the final determination by the applicable Defect Referee as to any Disputed Defect Matters, or within three (3) Business Days following the Cure Deadline (to the extent that Purchaser and Sellers’ Representative have agreed that Sellers have cured a Title Defect after Closing and on or before the Cure Deadline), Purchaser and Sellers’ Representative shall execute joint written instructions to the Escrow Agent to release from the Defect Deposit and/or the Additional Lease Deposit the applicable amount(s) in dispute to the Party or Parties that the Defect Referee has determined are entitled to such amount(s), or as agreed by the Parties, as applicable, in each case, (A) first, in cash, until all cash constituting the Defect Deposit and Additional Lease Deposit is distributed and (B) second, in shares of Parent Common Equity, based on the Share Price.

Except as otherwise expressly provided in this Agreement, all expenses incurred by Sellers in connection with or related to the authorization, preparation or execution of this Agreement, and the Exhibits and Schedules hereto and thereto, and all other matters related to the Closing, including all fees and expenses of counsel, accountants and financial advisers employed by Sellers and their Affiliates (including, prior to Closing, the Subject Companies and their Subsidiaries), shall be borne solely and entirely by Sellers, and all such expenses incurred by any Purchaser Party (excluding, however, any Transaction Costs) shall be borne solely and entirely by the Purchaser Parties.

Section 8.9 Records. Purchaser acknowledges and agrees that Sellers shall be entitled to retain a copy of the Records to the extent relating to the businesses of any Affiliate of any Seller other than any member of any Subject Company Group, but excluding for the avoidance of doubt, any Records that pertain only to the Assets (and not to any of the Excluded Assets or any other assets or properties held by any Seller or any Affiliate of any Seller), subject to the confidentiality restrictions set forth herein. At and after Closing, Purchaser shall, and shall cause each Subject Company to, preserve and keep a copy of all Records in any Subject Company’s and Purchaser’s possession for a period of at least seven (7) years after the Closing Date; provided that Purchaser may destroy books, records or documents from time to time and prior to the end of such period in accordance with its normal document retention policy as long as Purchaser first provides Sellers’ Representative with reasonable prior written Notice and gives the applicable Sellers reasonable opportunity, at such Seller’s sole cost and expense, to remove and retain all or any part of such Records. After such seven (7) year period, before any Purchaser Entity and/or any Subject Company shall dispose of any such Records, the Purchaser Parties and each Subject Company shall give Seller reasonable Notice to such effect, and each 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 such Seller may select. From and after the Closing Date, Purchaser shall, and shall cause each Subject Company to, provide Sellers and their respective Representatives with reasonable access (for the purpose of examining and copying at such Seller’s sole expense), at reasonable times and upon reasonable advance Notice, to the Records pertaining to Taxes with respect to periods prior to the Closing Date.

114

Section 8.10 Change of Name; Removal of Name. Notwithstanding any other provision of this Agreement to the contrary, from and after Closing, Purchaser agrees, on behalf of the Subject Company Groups and the Purchaser Group, that they (a) shall have no right to use the names “Black Swan”, “PetroLegacy”, “Piedra” or any similar name or any intellectual property rights related thereto or containing or compromising the foregoing, including any name or mark confusingly similar thereto or a derivative thereof (collectively, the “Subject Marks”), and (b) will not at any time hold themselves out as having any affiliation with any Seller or any of its Affiliates (other than any of the Subject Company Groups). In furtherance thereof, Purchaser shall (i) within thirty (30) days after the Closing Date, file all documentation reasonably necessary to change the legal name of each Subject Company with all applicable Governmental Authorities in all applicable jurisdictions and (ii) within sixty (60) days after the Closing Date remove, strike over or otherwise obliterate all Subject Marks from all Assets and materials, including, any Oil and Gas Properties, vehicles, business cards, schedules, stationary, packaging materials, displays, signs, promotional materials, manuals, forms, computer software and other materials. From and after the Closing: (A) no Purchaser Party shall object to (1) the formation by any Seller or its Affiliates of an entity with the words “Black Swan”, “PetroLegacy”, “Piedra” or any of the other Subject Marks in its name or (2) the use by any Seller or its Affiliates of the logo used by any Subject Company prior to the Closing as the logo for any other Person and (3) each Purchaser Party and each Subject Company shall provide such consents as may be reasonably requested in connection with the formation of such new Persons.

Section 8.11 Indemnification of Directors and Officers.

(a) For a period of six (6) years from and after the Closing, each Subject Company shall indemnify and hold harmless (and advance funds in respect of each), in the same manner as (and no broader than) required by the Governing Documents of the Subject Company Groups immediately prior to the Execution Date, each present and former director, manager, officer and employee of each Subject Company (in all of their capacities) (collectively, the “Subject Company Groups Indemnified Parties”), against any costs or expenses (including reasonable attorneys’ fees and expenses and disbursements), judgments, fines, losses, claims, Damages or liabilities incurred in connection with any Action, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that such Subject Company Groups Indemnified Party is or was a director, manager, officer or employee of any Subject Company, whether asserted or claimed prior to, at or after the Closing (including with respect to acts or omissions by directors or officers of each Subject Company in their capacities as such arising in connection with the transactions contemplated hereby), and shall, to the fullest extent permitted by Law, provide advancement of expenses to the Subject Company Groups Indemnified Parties, in all such cases to the same extent that such Persons are indemnified or have the right to advancement of expenses as of the Execution Date by the Subject Company Groups pursuant to the Governing Documents of any Subject Company and indemnification agreements, if any, in existence on the Execution Date.

(b) Purchaser and each Subject Company agree that, until the six (6) year anniversary date of the Closing Date, the Purchaser Parties shall not (and shall cause the Subject Companies not to) amend, repeal or otherwise modify the Governing Documents of any Subject Company in any manner that would adversely affect the rights to indemnification and advancement of expenses thereunder of individuals who at, and at any time prior to, the Closing were Subject Company Group Indemnified Parties.

115

(c) At or prior to Closing, Sellers shall cause the Subject Companies to obtain (and shall fully prepay, subject to reimbursement by Purchaser at Closing of fifty percent (50%) of the premium thereof) a “tail” policy from an insurer with substantially the same or better credit rating as the current carrier for the existing D&O Insurance of the Subject Company Groups (to the extent reasonably available at the applicable time), which (i) has a claims period of at least six (6) years from the Closing Date with respect to claims arising from facts or events that occurred on or before the Closing, and (ii) covers each Person covered by the D&O Insurance of the Subject Company Groups on terms with respect to coverage and in amounts no less favorable in the aggregate than the D&O Insurance of the Subject Company Groups, in each case, in effect on the Execution Date; provided, however, that Purchaser and/or any Subject Company shall not be required to pay an annual premium for the D&O Insurance in excess of three hundred percent (300%) of the annual premium currently paid by the Subject Company Groups for its existing D&O Insurance coverage; and provided, further, however, that if any annual premium for such insurance coverage exceeds three hundred percent (300%) of such existing annual premium, then the Subject Companies shall obtain as much coverage as reasonably practicable for a cost not exceeding such amount. After Closing, Purchaser shall cause such policy to be maintained in full force and effect, for its full term, and cause all obligations thereunder to be honored by the Subject Companies.

(d) The provisions of this Section 8.11 are (i) intended to be for the benefit of, and will be enforceable by, each Subject Company Groups Indemnified Party and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by Contract or otherwise.

(e) For a period of six (6) years after the Closing Date, if Purchaser or any Subject Company, or any of its or their respective successors or assigns, (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation, limited liability company, partnership or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, to the extent not assumed by operation of law, Purchaser shall require that the successors and assigns of such Person assume the indemnification obligations set forth in this Section 8.11.

Section 8.12 Employee Matters.

(a) Sellers have provided Purchaser a list of Business Employees to whom Purchaser has the right, but not the obligation, to offer employment with Purchaser or a post-Closing Affiliate of Purchaser as of and following the Closing (each, an “Optional Business Employee”). Such list is to include, to the extent permitted by applicable Law, each such Business Employee’s name and job title (such list, as updated in accordance with this Section 8.12(a), the “Business Employee List”). Seller shall update the Business Employee List from time to time after the Execution Date and/or upon request by Purchaser in order to maintain the accuracy thereof through the Closing (including to reflect any hires, termination or other updates to the Business Employee population effected in accordance with Section 8.12 and to correct any accidental or inadvertent errors or omissions). To the extent not already up-to-date, Seller shall update the Business Employee List immediately prior to the Closing Date.

116

(b) Purchaser may make such offers of employment to the Optional Business Employees (each, an “Optional Employee Offer”) on terms and conditions in its sole discretion, subject to compliance with applicable Law and the timing requirements set forth below. Purchaser shall make all Optional Employee Offers no later than thirty (30) days prior to the Closing Date and shall provide the Optional Business Employee at least seven (7) days to accept the offer of ongoing employment. Within two (2) days of extending any Optional Employee Offer, Purchaser shall notify Sellers of such offers. Within two (2) days of any Optional Business Employee’s acceptance or rejection of an Optional Employee Offer, Purchaser shall notify Sellers of such acceptance or rejection. With respect to any Business Employee who accepts an Optional Employee Offer, Purchaser shall, or shall cause its post-Closing Affiliate to, hire such Optional Business Employee (each such individual who commences employment with Purchaser or its post-Closing Affiliate, a “Continuing Employee”) effective as of the Closing. Purchaser shall retain, and indemnify and hold Sellers harmless from, all liabilities with respect to Purchaser’s selection, offer and retention process with respect to the Optional Business Employees, which liabilities, for the avoidance of doubt, shall not include any severance obligations from or related to Purchaser’s selection, offer and retention process with respect to the Optional Business Employees.

(c) Purchaser shall not, and shall cause its Affiliate not to, take any action in the ninety (90) days following the Closing that, to Purchaser’s Knowledge, would result in WARN Act liability for Sellers or their Affiliates.

(d) Notwithstanding anything herein to the contrary, each Business Employees who, as of the Closing Date, is (i) receiving or in an exclusion or elimination period for purposes of receiving short- or long-term disability benefits or (ii) not actively working as a result of an approved leave of absence (each, an “Inactive Business Employee”), shall remain an employee of a Seller or one of its Affiliates (other than the Subject Company Group). Sellers shall be solely responsible for the provision of benefits and compensation to, and all costs or other liabilities incurred with respect to, each Inactive Business Employee until and unless the employee presents himself or herself to Purchaser for active employment following the employee’s return to active employment with such Seller or Affiliate within ninety (90) days following the Closing Date (or such longer period as may be required by Law) and provides Purchaser with medical certification that he or she is able to perform the essential functions of his or her job with or without a reasonable accommodation within such time period. Each Optional Employee Offer to an Inactive Business Employee, if any, shall provide for employment with Purchaser effective as of the date such Inactive Business Employee is able to return to active work with or without a reasonable accommodation.

(e) 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 Seller Management Person or any Person listed on Schedule 8.12(e) (collectively, the “Restricted Persons”) to terminate his or her employment or engagement with Sellers or their Affiliates, or to otherwise alter such individual’s relationship with Sellers or their 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 8.12(e), 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 Sellers 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 8.12(e) are reasonable and necessary to protect the legitimate interests of Sellers and

117

constitute a material inducement to Sellers 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 8.12(e) 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. For the avoidance of doubt, Purchaser shall (or shall cause its Affiliates to) credit each Continuing Employee with all paid time off accrued and unused by such Continuing Employee through the Closing Date; provided that, to the extent required by applicable Law, all paid time off accrued and unused by such Continuing Employee through the Closing Date shall be paid by the Subject Company (or its relevant Affiliate) to the Continuing Employee if applicable Law requires the Subject Company (or its relevant Affiliate) to pay such paid time off accrued and unused by such Continuing Employee through the Closing Date. Nothing in this Section 8.12 shall obligate the Purchaser or its Affiliates to continue the employment of any such Continuing Employee for any specific period.

(f) Seller and its Subsidiaries agree that, notwithstanding the terms of any non-competition, non-solicit, non-disclosure, non-interference, or similar restrictive covenant between Seller or any Affiliate of Seller, including any Subject Companies, or any of its or their Subsidiaries (on the one hand) and any Continuing Employees (on the other hand) (the “RCAs”), such Continuing Employees shall be permitted to provide services to Purchaser and its Affiliates following the Closing, and Seller shall not (and shall cause its Affiliates and Subsidiaries not to) seek to enforce the terms of any such RCA following the Closing.

(g) Sellers and their Affiliates (other than the members of the Subject Company Group) shall assume, retain and shall be solely responsible for any and all liabilities or obligations relating to or at any time arising under or in connection with any Seller Plan and any other compensation or benefit plan, program, agreement, policy or arrangement of any kind at any time maintained, sponsored or contributed to or required to be contributed to by Seller or any of its Affiliates (including the Subject Company Group) or under or with respect to which Seller or any of its Affiliates (including the Subject Company Group) has (or has had) any current or contingent liability or obligation, including the responsibility for satisfying the continuation coverage requirements of Section 4980B of the Code for all “M&A qualified beneficiaries” as such term is defined in Treasury Regulation Section 54.4980B-9.

(h) Sellers and their respective Affiliates (other than any Subject Company or its Subsidiaries) shall assume, retain and shall be solely responsible for (i) any and all liabilities or obligations relating to or at any time arising under or in connection with Sellers’ and their respective Affiliates’ (including, for any period prior to Closing, any Subject Company’s) employment or engagement of any individual who does not become a Continuing Employee and (ii) any and all liabilities or obligations relating to or arising under or in connection with Sellers’ and their respective Affiliates’ (including, for any period prior to Closing, any Subject Company’s) employment or engagement of any Continuing Employee to the extent existing or arising on or prior to the time such individual becomes a Continuing Employee (which shall be “Excluded Assets” for all purposes hereunder).

118

(i) The provisions of this Section 8.12 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 Business Employee, Seller Management Person, or other current or former employee of a member of the Subject Company Group, Sellers or any of their 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 8.12) under or by reason of any provision of this Section 8.12, including any right to continued employment with Purchaser or any of its Affiliates or to any particular term or condition of employment. Nothing contained herein, express or implied, shall be (i) deemed an amendment, modification, or termination of any benefit or compensation plan, program, policy, agreement or arrangement or (ii) construed to prevent Purchaser or any of its Affiliates from terminating, amending, entering into, or modifying to any extent or in any respect any benefit or compensation plan, program, policy, agreement or arrangement that Purchaser or any of its Affiliates may establish or maintain at any time.

Section 8.13 Credit Support. The Parties agree and acknowledge that neither (a) the Credit Support provided by or on behalf of any Seller or its Affiliates (excluding the Subject Company Groups) in support of the obligations of the Subject Company Groups nor (b) the Credit Support provided by or on behalf of the Subject Company Groups to the extent set forth on Schedule 8.13 (collectively, the “Existing Credit Support”) shall be maintained after Closing. At or prior to Closing, the Purchaser Parties shall post, and provide evidence of, all applicable replacement Credit Support for the Existing Credit Support set forth on Schedule 8.13, with such replacement Credit Support to be in form and substance satisfactory to the applicable Third Party or Governmental Authority and sufficient to permit the prompt cancellation of the Existing Credit Support posted by Sellers or any of their Affiliates (other than the Subject Company Groups). In connection with Closing, the Purchaser Parties shall use commercially reasonable efforts (at no out of pocket cost, expense or liability to any Purchaser Party or its Affiliates, other than costs of obtaining the replacement Credit Support described in the preceding sentence and any fees, costs and expenses associated with such replacement Credit Support) to cooperate with Sellers in obtaining the release or return to Sellers of all Existing Credit Support or the return or reimbursement of the Sellers for any cash deposits constituting Existing Credit Support.

Section 8.14 Hedging Matters.

(a) At Closing,(i) the Subject Company Groups shall cause the termination, liquidation and unwinding of any remaining Existing Hedges, (ii) the Unadjusted Purchase Price shall be adjusted pursuant to Section 2.4(c) with respect to the Existing Hedges and (iii) a portion of the Closing Payment and/or the Closing Distribution shall be disbursed to the applicable Hedge counterparties in an amount equal to the Hedge Losses attributable to such Existing Hedges, if any, payable in connection with such termination, liquidation and unwinding.

(b) In the event that this Agreement is not terminated on or prior to June 30, 2023, from and after June 30, 2023 and prior to Closing, any Subject Company, Seller or any Affiliate of Seller may execute and enter into any Hedges to the extent such Subject Company reasonably determines such Hedges are necessary to satisfy such Subject Company’s, Seller’s or such Affiliate’s obligations under any Credit Documents and any and all such Hedges shall constitute “Additional Hedges”; provided that, Sellers shall consult with Purchaser in good faith prior to entering into

119

any such Additional Hedges, and will use commercially reasonable efforts to limit the terms of any Additional Hedge to the shortest term permissible under the Credit Documents. Subject to the foregoing, at and after Closing, all Additional Hedges held by any Subject Company shall be the assets, right and responsibility of the Purchaser Parties and the Subject Company Groups; provided that the Sellers, on the one hand, and the Purchaser Parties, on the other hand, shall each (a) be responsible for and bear fifty percent (50%) of all Hedge Losses and other costs and expenses attributable to or arising out of such Additional Hedges, (b) be entitled to fifty percent (50%) of all Hedge Gains and all other proceeds attributable to or arising out of such Additional Hedges. To the extent requested by Purchaser prior to Closing, the applicable Subject Company and Purchaser shall take such commercially reasonable efforts as requested by Purchaser to cause the applicable Hedge counterparties with respect to the Additional Hedges, to execute at Closing such novation agreements as requested by Purchaser to novate any Additional Hedges to a Purchaser Entity at Closing, with any novation, assignment or transfer fees and expenses payable to any such Hedge counterparties borne fifty percent (50%) by Sellers, on the one hand, and fifty percent (50%) by Purchaser, on the other hand; provided, however, in the event that such novations are, as of the date three (3) Business Days prior to Closing, not reasonably expected to occur at Closing, then (A) the applicable Subject Company shall use commercially reasonable efforts to obtain and deliver to Purchaser a written estimated quote from the applicable Hedge counterparty for the amount that such counterparty would pay (expressed as a positive number) or require to be paid (expressed as a negative number) in order to terminate, liquidate and unwind such Additional Hedges as of the date such estimated quotation is provided, and Purchaser shall, in its sole discretion, have the right to direct any negotiation and discussion with the applicable Hedge counterparty with respect to the termination, liquidation and unwinding of such Additional Hedges, including making any determination or decision with respect to price or costs to terminate, liquidate or unwind such Additional Hedges, (B) at Closing, (1) the applicable Subject Company shall cause the termination, liquidation and unwinding of such Additional Hedges, (2) the Unadjusted Purchase Price shall be adjusted pursuant to Section 2.4(c) and a portion of the Closing Payment shall be disbursed to the applicable Hedge counterparties in an amount equal to fifty percent (50%) of the Hedge Losses attributable to such Additional Hedges, if any, payable in connection with such termination, liquidation and unwinding.

Section 8.15 Seismic Licenses.

(a) Purchaser acknowledges that one or more Subject Company holds the data and geophysical licenses and permits described on Schedule 8.15 (each a “Seismic License”). Pursuant to the terms of such Seismic Licenses, the consummation of the transactions contemplated hereunder may require the consent of the applicable licensor, or the payment of one or more transfer, assignment or change of control fees or payments unless the applicable Subject Company cancels or terminates such Seismic License.

(b) With respect to those Seismic Licenses described on Part A of Schedule 8.15, Purchaser has elected that at or after Closing (i) the applicable Subject Company shall pay to the applicable Third Party under such Seismic License any and all transfer, assignment or change of control fees or payments required under such Seismic Licenses in connection with the consummation of the transactions contemplated hereunder, (ii) in no event shall such payment of fees or payments result in any downward reduction to the Unadjusted Purchase Price and (iii) Purchaser and the Subject Company Groups shall, after Closing, indemnify, defend and hold harmless each member of the Seller Group from any and all Damages arising out of the payment, mispayment or failure to pay such fees and payments.

120

(d) Notwithstanding anything herein to the contrary, Purchaser may elect to have the Seismic Licenses listed on Part A of Schedule 8.15 moved to Part B of Schedule 8.15 at any time and for any reason upon written notice to Sellers’ Representative within ten (10) days after the Execution Date.

(h) take any action that would or would reasonably be expected to prevent or materially delay the Closing and the consummation of the transactions contemplated by this Agreement or the Transaction Documents; or

122

release and waive any and all claims that any of them may have under such arrangements as of the termination date; provided that, Purchaser shall have the right, upon written notice to Sellers not less than ten (10) days prior to the Target Closing Date, to notify Sellers that it elects to defer termination of one or more Affiliate Arrangements as are reasonably necessary for the applicable counterparty thereto to continue to provide accounting services for the Subject Companies (the “Extended Affiliate Arrangements”) from the Closing Date through and until the last day of the calendar month following the date that Closing occurs (the “Accounting Transition Period”) on substantially the same terms as are reflected in such Affiliate Arrangements immediately prior to Closing; provided, however, Purchaser shall pay such Affiliate of Seller a fee equal to Two Hundred and Fifty Thousand Dollars ($250,000) per month (pro-rated for any partial months) for such Extended Affiliate Arrangements after the Closing Date (together with any amount of out-of-pocket expenses paid or payable to any Person that is not an Affiliate of the applicable Seller in connection with such Extended Affiliate Arrangements). For the avoidance of doubt, if Purchaser makes such election, then any and all waivers and releases from Damages set forth in this Section 8.19 or in Section 13.3 shall not extend to, and no Party hereto or its Affiliate shall be deemed to have waived or released any Person with respect to, any claims, losses or other Damages arising from or relating to the performance of services arising from or related to the performance of services under any such Extended Affiliate Arrangements to the extent pertaining to the Accounting Transition Period.

(b) Subject to (and except as provided in) Section 8.19(a), and without limiting the Parties’ rights or obligations set forth in Section 2.4 and Section 2.5, as of Closing, except with respect to any obligations or liabilities arising pursuant to the Affiliate Arrangements set forth on Schedule 8.19, Sellers hereby cancel and release from Damages, and shall cause Sellers’ Affiliates (other than the Subject Companies) to cancel and release from Damages, any indebtedness or payables outstanding as of Closing from any Subject Company or its Subsidiaries to Sellers or their respective Affiliates (other than the Subject Companies or their Subsidiaries), in each case, other than (i) claims for unpaid amounts that would, prior to Closing, constitute “Permitted Leakage” (provided that any such claim shall be made on or before one hundred twenty (120) days after the Closing Date) and (ii) any Damages for which Purchaser or any Subject Company is obligated to provide indemnity under Section 13.1.

Section 8.20 Additional Leases.

(a) From and after the Effective Time until 5:00 p.m. Central Time on the date that is one (1) Business Day prior to the Closing Date (the “Additional Lease Acquisition Deadline”), any Subject Company may acquire title to any Additional Lease located within the geographic areas identified on Part A of Schedule 8.20 (each such area, an “Acquisition Area”). For purposes hereof, the term “Additional Lease” means a Hydrocarbon lease that satisfies all of the following criteria: (i) is acquired by a member of the Subject Company Groups from a Third Party 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 December 31, 2023, (iv) entitles the lessee thereunder to a Net Revenue Interest in the applicable Subject Formation(s) equal to or greater than the product of (x) seventy-five percent (75%) multiplied by (y) 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 lease (A) described on any Annex to Exhibit A-1 or any renewals or extensions of leases described on Exhibit A-1, or (B) any leases that cure any Title Defects.

123

(b) If any member of a Subject Company Group acquires an Additional Lease prior to the Additional Lease Acquisition Deadline, the applicable 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 Subject Company’s (A) good faith estimate of the Additional Lease Purchase Price attributable to such Additional Lease, which such estimate shall include a calculation of the amounts set forth in both clauses (a) and (b) of the definition of “Additional Lease Purchase Price” and (B) the 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 Subject Company’s possession that are reasonably necessary for the Purchaser to verify or confirm such Subject Company’s title to each such Additional Lease. Thereafter, Purchaser shall have until the earlier of the date that is the day before the Closing Date and the date five (5) Business Days after receipt of such Additional Lease Notice to notify such Seller whether it elects to acquire (or to have the applicable Subject Company retain) the Additional Leases subject thereto (each such Additional Lease that Purchaser elects to acquire, or for the Subject Company to retain, being referred to herein as an “Accepted Additional Lease”); provided, however, (x) the Additional Leases identified on Part B of Schedule 8.20 that are located within the boundaries of a DSU that is operated by any Subject Company, in each case, are deemed to be Accepted Additional Leases for all purposes hereunder and (y) the deadline for Purchaser to elect whether to acquire (or to have the applicable Subject Company retain) the remaining Additional Leases identified on Part B of Schedule 8.20 shall be 5:00 PM Central Time on April 7, 2023. The Accepted Additional Leases acquired by the members of the Subject Company Groups after the Effective Time shall be included in and constitute Leases as of the Closing Date and the Unadjusted Purchase Price shall be increased by aggregate Additional Lease Purchase Prices attributable to all such Accepted Additional Leases in accordance with Section 2.4(j); provided that, unless Purchaser otherwise agrees in writing, the Additional Lease Purchase Price with respect to any Additional Leases that cover mineral interests owned by any Affiliate or Subsidiary of a Seller (including each Excluded Subsidiary) shall be deemed to be Zero Dollars ($0.00). With respect to any Additional Lease for which an Additional Lease Notice is properly delivered to Purchaser hereunder, but which is not an Accepted Additional Lease, (1) the applicable Seller shall cause the applicable Subject Company holding such Additional Lease, prior to Closing, to exclude the Additional Lease from the Assets, (2) such Subject Company and the applicable designated assignee thereof shall execute and deliver an Excluded Asset Assignment at Closing with respect to such Additional Lease, and (3) such Additional Lease shall thereafter be deemed to be an “Excluded Asset” for all purposes of this Agreement.

(c) The Sellers and the Purchaser Parties shall use good faith efforts to agree on the interpretation and effect of this Section 8.20 and the validity and determination of all Additional Leases and Additional Lease Purchase Prices with respect thereto prior to Closing. If the Sellers and the Purchaser Parties are unable to agree on the interpretation and effect of this Section 8.20, whether a Hydrocarbon lease constitutes an Additional Lease, the existence or amount of any

124

Additional Leases and Additional Lease Purchase Prices, or any other matter related to title to any Additional Leases for which the applicable Subject Company has delivered an Additional Lease Notice then all such disputed matters, interpretations and effect of this Section 8.20 shall be exclusively and finally resolved by the Title Referee in accordance with the terms of Section 3.2(i), mutatis mutandis.

Section 8.21 R&W Insurance Policy. The Parties acknowledge and agree that, the Purchaser has or within two (2) Business Days following the Execution Date will procure the R&W Conditional Binder in connection with the R&W Insurance Policy and that, following the Execution Date, the Purchaser expects that the R&W Insurance Policy will become effective as of the Execution Date. The Purchaser Parties shall not amend, modify, supplement, or restate the provisions of Section VIII(B)(i) of the R&W Insurance Policy attached hereto as Exhibit D benefitting the Sellers (or any Affiliate or direct or indirect past or present shareholder, member, partner, stockholder, employee, director or officer (or the functional equivalent of any such position) of Seller) in any manner or respect adverse to such parties without the prior written consent of the Sellers’ Representative. For the avoidance of doubt, the Parties acknowledge and agree that (i) the procurement by the Purchaser of the R&W Insurance Policy is not a condition to Closing, and (ii) all costs, expenses, premiums and fees with respect to obtaining the R&W Insurance Policy will be borne fifty percent (50%) by the Purchaser Parties, and fifty percent (50%) by the Sellers; provided, however, to the extent any such costs, expenses, premiums and fees exceed Eleven Million Dollars ($11,000,000) in the aggregate, Purchaser shall bear and pay one hundred percent (100%) of such excess.

Section 8.22 Financing Cooperation and Efforts.

(a) Each Subject Company Group shall deliver to Parent, at least one (1) Business Day prior to the Closing Date, duly executed Lien releases and other security release and termination documentation in form reasonably satisfactory to Parent, such that all Liens on the equity interests of each Subject Company Group and all Liens on their respective assets and equity securing the Credit Documents shall be released and terminated upon the consummation of the Transactions contemplated by this Agreement, together with an authorization from the lenders under the Credit Documents that, concurrently with Closing, each Subject Company Group or any designee thereof to file any and all termination statements or releases evidencing such release of Liens, together with any applicable documents necessary to evidence the release and termination of all Liens on each Subject Company Group and their respective assets and equity securing, and any guarantees by the Subject Company Groups or any other Person in respect of, such Credit Documents.

Any such cooperation shall be provided at Parent’s expense for reasonable and documented third party fees and expenses. For the avoidance of doubt, any failure of the Subject Companies to fulfill their obligations under this Section 8.22(b) shall not be deemed a breach of this Agreement or excuse performance of the Parent to consummate the Transactions, so long as the Subject Companies are acting reasonably and diligently in good faith to fulfill such obligations.

(c) Notwithstanding anything to the contrary in Section 8.22(b), (i) no Subject Company nor any of their respective Affiliates or any of their respective equityholders or governing bodies shall be required to pass resolutions or consents to approve or authorize the execution of the Financing Documents and execute or deliver any certificate, document, instrument or agreement in connection therewith or the Financing that is effective prior to the Closing (except for the authorization letters, documentation or certifications, comfort letters, representation letters and consents referred to in Section 8.22(b)); (ii) no obligation of any Subject Company or any of its Affiliates or any of their respective equityholders, members or Representatives under any certificate, document, instrument or agreement, entered into pursuant to the foregoing shall, without such Person’s prior express written consent, be effective until Closing (except for the authorization letters, documentation or certifications, comfort letters, representation letters and consents referred to in Section 8.22(b)); (iii) no Subject Company nor any of their respective Affiliates or any of their respective equityholders, members or

127

Representatives shall be required to pay any commitment or other similar fee, or incur any other cost or expense or liability, in connection with the Financing or any other action taken in connection with Section 8.22(b); (iv) no such cooperation shall be required to the extent that any such action, in the good faith belief of any Subject Company, would (x) unreasonably interfere with the ongoing business or operations of such Subject Company or any of its respective Affiliates or (y) subject any director, manager, officer or employee of any Subject Company or any of their respective Affiliates or Subsidiaries thereof to any actual or potential personal liability; (v) no such cooperation shall be required to the extent it would reasonably be expected to conflict with or violate any Law, or result in the contravention of, or result in a violation or breach of, or default under, any Material Contract in effect on the date hereof; (vi) no such cooperation shall be required to the extent that any Subject Company or any of their respective Subsidiaries determines that such cooperation would result in a loss or waiver of or jeopardize any attorney-client privilege, attorney work product or other legal privilege (provided, that the Subject Companies and their respective Subsidiaries shall use reasonable efforts to allow for cooperation in a manner that does not result in the events set out in this clause (vi)) and (vii) no such cooperation shall be required to the extent that any Subject Company or any of their respective Subsidiaries is required to create, provide, update or have audited or reviewed any financial statements except for the Financing Information and those explicitly contemplated by Section 8.22(b). Parent shall be responsible for all fees and expenses related to the Financing, including the compensation of any contractor or advisor of any Seller or Subject Company to the extent directly related to actions taken pursuant to Section 8.22. Accordingly, notwithstanding anything to the contrary herein, Parent shall promptly, upon written request by a Seller or Subject Company, reimburse such Seller or Subject Company for all reasonable and documented out-of-pocket costs and expenses (including reasonable and documented compensation or other fees of any contractor or advisor) to the extent incurred by such Seller and/or Subject Company and its Subsidiaries and their respective Representatives in connection with the Financing (including related to compliance with Section 8.24), including the cooperation of such Seller and the Subsidiaries thereof contemplated by this Section 8.22, and shall indemnify and hold harmless Sellers, Subject Companies and the respective Subsidiaries thereof and their respective Representatives from and against any and all losses suffered or incurred by any of them in connection with their compliance with this Section 8.22, the arrangement of the Financing or any information (including Financing Information) used in connection therewith, in each case, except to the extent suffered or incurred as a result of the gross negligence, willful misconduct or bad faith by such Seller or Subject Company or such Person’s Subsidiaries thereof or, in each case, such Person’s Representatives.

(d) Parent shall use its reasonable best efforts to take, or cause to be taken, all actions and do, or cause to be done, all things, necessary, proper or advisable to arrange, consummate and obtain the Financing on or prior to the Closing Date in an aggregate amount sufficient, together with cash on hand, to enable Purchaser and/or Parent to pay the Closing Payment on the Closing Date to or on behalf of Sellers. Such actions shall include, but not be limited to, using reasonable best efforts to: (i) maintain in effect the Debt Commitment Papers; provided that Parent may replace or amend, supplement or waive provisions of, the Debt Commitment Papers (including adding new lenders, lead arrangers, bookrunners, syndication agents or similar entities to the Debt Commitment Papers pursuant to the terms thereof, providing for the assignment, novation and reallocation of a portion of the financing commitments contained therein and to grant customary approval rights to such additional entities in connection with their addition or appointment or increase the amount of commitments under the Financing Documents or any other definitive

128

agreements in connection with the Financing) in accordance with this Section 8.22(d) and Section 8.22(e) below; (ii) satisfy on a reasonably timely basis all Financing Conditions (unless such conditions are waived) that are within Parent’s or its Subsidiaries’ control; and (iii) negotiate, execute and deliver Financing Documents on terms which (taken as a whole) are no less favorable to Parent than the terms contained in the Debt Commitment Papers (including any “market flex” provisions of the Fee Letter) with respect to the consummation of the Transactions described herein; provided that, in the case of each of clauses (i), (ii) and (iii), the Debt Commitment Papers may be terminated, and commitments thereunder reduced to the extent and only to the extent that after giving effect to such termination or reduction the Parent shall have sufficient cash on hand, together with any remaining commitments under the Debt Commitment Papers, to enable the Parent and the Purchaser to pay the Closing Payment on the Closing Date and otherwise consummate the Transactions. Parent shall not, without the prior written consent of Sellers’ Representative (not to be unreasonably withheld, conditioned or delayed), permit any amendment, supplement or modification to, or any waiver of any provision or remedy under, or replace, or enter into any other agreements, side letters or arrangements relating to, the Debt Commitment Papers, if such amendment, supplement, modification, waiver, replacement or other agreements, side letters or arrangements (provided that the existence or exercise of “market flex” provisions contained in the Fee Letter shall be deemed not to constitute a modification or amendment of the Debt Commitment Papers) to the Debt Commitment Papers would (A) reasonably be expected to make the timely funding of the Financing or satisfaction of the conditions to obtaining the Financing materially less likely to occur, (B) materially and adversely affect the ability of Parent to enforce its rights against any of the other parties to the Debt Commitment Papers as so amended, supplemented, modified, waived or replaced, relative to the ability of Parent to enforce its rights against any of such other parties to the Debt Commitment Papers as in effect on the date hereof or (C) add new or additional conditions, or otherwise expand upon the conditions precedent to the Financing as set forth in the Debt Commitment Papers, or modify the terms of the Financing, in each case in a manner that would reasonably be expected to materially prevent, impede or delay the consummation of the Transactions; provided that, in each case, the Debt Commitment Papers may be terminated, and commitments thereunder reduced to the extent and only to the extent that after giving effect to such termination or reduction the Parent shall have sufficient cash on hand, together with any remaining commitments under the Debt Commitment Papers, to enable the Parent and the Purchaser to pay the Closing Payment on the Closing Date and otherwise consummate the Transactions. Upon any such amendment, supplement, modification, waiver or replacement of the Debt Commitment Papers in accordance with this Section 8.22(d) or Section 8.22(e) below, Parent shall promptly deliver to Sellers’ Representative a true and complete copy thereof (redacted in a customary manner with respect to fee amounts, economic terms, “market flex” provisions and other customary terms), and the terms “Debt Commitment Letter,” “Debt Commitment Papers” and “Financing” shall refer to the Debt Commitment Papers as so amended, supplemented, modified, waived or replaced and the Financing contemplated thereby. Parent shall keep Sellers’ Representative informed on a reasonably current basis and in reasonable detail of the status of its efforts to arrange and obtain any Financing upon written request by Sellers’ Representative therefor; provided that, in no event shall Parent be under any obligation to disclose any information that may not be disclosed in accordance with the requirements of applicable Laws.

129

(e) Parent shall give Sellers’ Representative prompt written notice of (i) any material breach, default, termination or written repudiation by any party to the Debt Commitment Papers of which Parent or any of its Subsidiaries becomes aware; (ii) the receipt by Parent of any written notice or other written communication from any Financing Source with respect to any actual or potential breach, default, termination or written repudiation by such party to the Debt Commitment Papers, or of any provisions thereto; and (iii) the occurrence of any event or development that Parent expects to have a materially adverse impact on the ability of Parent to obtain the timely funding under the Debt Commitment Letter on the Closing Date or to consummate the Transactions, in each case, other than on account of any reductions in the commitments thereunder to the extent and only to the extent that after giving effect to such termination or reduction the Parent shall have sufficient cash on hand, together with any remaining commitments under the Debt Commitment Papers, to enable the Parent and the Purchaser to pay the Closing Payment on the Closing Date and otherwise consummate the Transactions. As soon as reasonably practicable, but in any event within five (5) Business Days of the date Sellers’ Representative delivers to Parent a written request, Parent shall provide any information reasonably requested by Sellers’ Representative relating to any circumstance referred to in the immediately preceding sentence. Without limiting Parent’s obligations hereunder, if any portion of the Financing becomes unavailable (other than as a result of reductions contemplated pursuant to the Debt Commitment Letter or otherwise permitted by Section 8.22) or Parent becomes aware of any event or circumstance that makes any portion of the Financing unavailable, in each case, on the terms and conditions contemplated in the Debt Commitment Papers, Parent shall (A) notify the of the occurrence thereof and the reasons therefor on a reasonably prompt basis; (B) use its reasonable best efforts to obtain, as promptly as practicable after the occurrence of such event, alternative financing from the same or alternative financing sources (1) in an amount at least equal to the amount of the Financing or such unavailable portion thereof and (2) which alternate financing shall not otherwise be on terms (including structure, covenants and pricing) materially less favorable to Parent than the terms and conditions set forth in the Debt Commitment Papers (including any “market flex” provisions contained in the Fee Letter); (C) keep Sellers’ Representative reasonably informed on a current basis of the status of its efforts to consummate such alternative financing; and (D) provide Sellers’ Representative with true and complete fully executed copies of the commitment documentation with respect to any new financing. Notwithstanding the foregoing, in no event shall Parent be under any obligation to disclose any information that may not be disclosed in accordance with the requirements of applicable Laws.

Section 8.23 Litigation Support. Each Seller shall, and shall cause its Affiliates and then-current officers and employees (with respect to each Seller, such Seller’s “Litigation Support Group”) to, reasonably cooperate with the Purchaser Parties and their Subsidiaries (including, after the Closing Date, each of the Subject Companies and their Subsidiaries) in the prosecution, mitigation, defense or settlement of the matters set forth on Schedule 4.5, Schedule 5.8, or that required disclosure on Schedule 4.5 or Schedule 5.8 as of the Execution Date (or that first arose after the Execution Date, but would have require disclosure on such schedules if arising prior to the Execution Date), regardless of whether such matter is listed on Schedule 4.5 or Schedule 5.8), including by providing Purchaser Parties, their Affiliates and their legal counsel, as applicable, reasonable access, to the extent such access is within the control of such Seller, during normal business hours to current officers, directors, employees, agents, records, documents, data and other information as such Purchaser Party or Affiliate thereof may reasonably request, to the extent maintained by or under the possession or control of any such Seller or its Litigation Support Group; provided that such Seller and its Litigation Support Group may restrict the foregoing access or the provision of such information to the extent that, upon advice of counsel, (a) applicable Law or

130

Contract requires such Person to restrict or prohibit such access or the provision of such information, (b) providing such access or disclosing such information would reasonably be expected to waive the protection of attorney-client privilege or similar legal privilege of such Person (other than any Subject Company Group) or (c) providing such access or disclosing such information would reasonably be expected to breach any duty of confidentiality to a Third Party. If such Seller or its Litigation Support Group restricts access or withholds information on the basis of the foregoing clauses (a) through (c), such Seller shall (or shall cause its Litigation Support Group to), to the extent legally permissible and without waiving any attorney-client privilege or similar legal privilege of such Seller or its Litigation Support Group (other than any Subject Company Group), inform the Purchaser Parties as to the general nature of what is being restricted or withheld and the reason therefor, and use commercially reasonable efforts to make appropriate substitute arrangements to permit access to or disclosure of the relevant information in a manner that does not have such restrictions. The Purchaser Parties shall reimburse such Seller or its Litigation Support Group for their reasonable, documented, out-of-pocket expenses paid to Third Parties in performing their respective obligations under this Section 8.23 (including reasonable fees and expenses of legal counsel, if applicable).

Section 8.24 Financing Information.

(a) Each Subject Company shall (i) deliver to Parent, as promptly as reasonably practicable after the date hereof, the applicable Financing Information as of and for the years ended December 31, 2022 and 2021 and (ii) use reasonable best efforts to deliver to Parent, within forty-five (45) days after the end of any fiscal quarter ending on and after March 31, 2023, or in any event shall deliver to Parent as promptly as reasonably practicable thereafter, the applicable Financing Information as of the end of such quarter and for the period from January 1, 2023 to the end of such quarter, together with the corresponding period of 2022 (such Financing Information for the fiscal quarter ended March 31, 2023, described in this clause (ii), the “Specified Financing Information”).

(b) In connection with filings by Parent with the SEC under securities Laws applicable to Parent (“Parent Filings”), as well as the Financing, each Subject Company shall use its commercially reasonable efforts prior to and after the Closing to (i) cooperate with Parent in connection with Parent’s preparation of pro forma financial statements that comply with the rules and regulations of the SEC to the extent required for Parent Filings and the Financing, including the requirements of Regulation S-X; (ii) in connection therewith, provide and make reasonably available upon reasonable notice and during regular business hours any and all Records in such Subject Company’s or its Affiliates’ possession or control and to which such Subject Company’s or its Affiliates’ personnel have reasonable access, in each case as reasonably required by Parent in order to prepare such pro forma financial statements; provided that Parent shall be solely responsible for any costs or expenses associated therewith, including, for avoidance of doubt, any such costs and expenses associated with the storage, retrieval and maintenance of records for the foregoing purposes; and (iii) cause its accountants, reserve engineers, counsel, agents and other Third Parties to cooperate with Parent and Parent’s Representatives in connection with the preparation of such pro forma financial statements; provided that Parent shall be solely responsible for any costs or expenses associated therewith. The obligations of the Subject Companies, the Sellers, their Affiliates and their accountants, reserve engineers, counsel, agents and other Third Parties under this Section 8.24(b) shall not extend beyond the earlier of (i) the date on which Parent files its Form 10-K with the SEC for the fiscal year ending December 31, 2024, (ii) the date on which Parent is required to make such Form 10-K filing with the SEC and (iii) March 31, 2025.

131

Section 8.25 Consents. After the Execution Date and prior to the Closing, each Seller shall, or shall cause its respective Subject Company Group to, use commercially reasonable efforts, but excluding (a) making any expenditures or payments or (b) granting any accommodation (financial or otherwise) to any Third Party, to obtain consent, in form and substance reasonably satisfactory to Purchaser, from any party to a Lease or Contract with a member of its respective Subject Company Group that is required to be obtained in connection with the execution, delivery and performance by Sellers or the applicable Subject Company Group of this Agreement and the Transaction Documents.

Section 8.26 Assignment of Certain Assets. At or prior to the Closing (or, with respect to any interests that are identified after Closing or were omitted from any assignment made prior to Closing, as soon as reasonably practicable), Piedra III Seller and Piedra IV Seller, as applicable shall, and shall cause their respective Affiliates to, as applicable, use reasonable best efforts to execute and deliver to the applicable Piedra Subject Company (or its Subsidiaries), as assignees, one or more assignments and bills of sale on a mutually agreed form causing such Person to assign all of its respective interest in and to any Contracts, Surface Rights and Rights of Way, Permits, Equipment or other Assets (but expressly excluding any Oil and Gas Properties, Business Employees, any Plan or any office equipment) that were, prior to the Seller Reorganization, used or held for use primarily in connection with the ownership and operation of the Oil and Gas Properties and are reasonably necessary for the continued operation of the Oil and Gas Properties, but were assigned, conveyed or retained by a Person other than a member of the applicable Piedra Company.

TAX MATTERS

Section 11.1 Company Taxes.

(a) Solely for purposes of determining the amount of any Pre-Effective Time Subject Company Group Taxes and Post-Effective Time Subject Company Group Taxes in connection with the application of Section 2.4, Section 2.5 and Section 2.7, (i) Subject Company Group Taxes that are attributable to the severance or production of Hydrocarbons (other than such Subject Company Group Taxes that are Income Taxes or that are ad valorem, property or similar Subject Company Group Taxes imposed on a periodic basis) shall be allocated to the Tax period (or portion of any Straddle Period) in which the severance or production giving rise to such Subject Company Group Taxes occurred; (ii) Subject Company Group Taxes that are based upon or related to sales or receipts or imposed on a transactional basis (other than such Subject Company Group Taxes that are Income Taxes, are ad valorem, property or similar Subject Company Group Taxes imposed on a periodic basis, or described in clause (i)), shall be allocated to the Tax period (or portion of any Straddle Period) in which the transaction giving rise to such Subject Company Group Taxes occurred; (iii) Subject Company Group Taxes that are ad valorem, property or other similar Subject Company Group 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 Subject Company Group 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; and (iv) Subject Company Group Taxes that are Income Taxes payable with respect to any 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 determining (x) the amount of such Subject Company Group Taxes that

137

would be payable if the Straddle Period ended on the date immediately preceding the date on which the Effective Time occurs, which amount shall be a Pre-Effective Time Subject Company Group Tax, and (y) the amount of such Subject Company Group Taxes that would be payable if the Straddle Period began on the date on which the Effective Time occurs, which amount shall be a Post-Effective Time Subject Company Groups Tax.

(b) To the extent the actual amount of a Subject Company Group Tax is not known at the time an adjustment is to be made with respect to such Subject Company Group Tax pursuant to Section 2.4, Section 2.5 or Section 2.7 as applicable, the Parties shall utilize the most recent information available in estimating the amount of such Subject Company Group Tax for purposes of such adjustment.

Section 11.2 Transfer Taxes and Recording Fees. Purchaser shall bear and pay fifty percent (50%) of, and Sellers shall bear and pay fifty percent (50%) of, any sales, use, transfer, stamp, documentary, registration, excise or similar Taxes incurred or imposed with respect to the transactions described in this Agreement (“Transfer Taxes”); provided, however, that Seller shall bear all of the Transfer Taxes (if any) associated with the assignment of any Excluded Assets pursuant to the Excluded Assets Assignment. 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 the Subject Securities to Purchaser. Each Seller and Purchaser shall reasonably cooperate in good faith to minimize, to the extent permissible under applicable Law, the amount of any such Transfer Taxes.

Section 11.3 Tax Returns. Sellers’ Representative shall prepare and file (or cause to be prepared and filed) all Seller Combined Returns and shall timely pay (or cause to be paid) all Taxes with respect to such Seller Combined Returns. Purchaser shall prepare or cause to be prepared all Tax Returns of any Subject Company Group with respect to Subject Company Group Taxes for all Pre-Effective Time Periods and Straddle Periods, in each case, that are required to be filed after the Closing Date, other than the Seller Combined Returns (“Purchaser Prepared Returns”). With respect to each such Purchaser Prepared Return that is required to be filed (taking into account any applicable extensions) after the Closing Date and before the date on which the Adjusted Purchase Price is finally determined pursuant to Section 2.7(b), (a) such Purchaser Prepared Return shall be prepared on a basis consistent with past practice except to the extent otherwise required by applicable Laws, (b) Purchaser shall, reasonably in advance of the due date of each Purchaser Prepared Return (taking into account any applicable extensions), deliver a draft of any such Purchaser Prepared Return (together with all supporting documentation and workpapers) to Sellers’ Representative for its review and comment and (c) Purchaser will cause such Purchaser Prepared Return (as revised to incorporate Sellers’ Representative’s reasonable comments) to be timely filed and provide a copy thereof to Sellers’ Representative. Purchaser shall pay or cause to be paid all Taxes shown as due and owing on such Purchaser Prepared Returns to the appropriate Governmental Authority. The Parties agree that (x) this Section 11.3 is intended to solely address the timing and manner in which certain Tax Returns and Subject Company Group Taxes shown thereon are paid to the applicable Governmental Authority, and (y) nothing in this Section 11.3 shall be interpreted as altering the manner in which Subject Company Group Taxes are allocated to and economically borne by the Parties.

138

Section 11.4 Cooperation. 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 imposed on or with respect to the assets, operations or activities of any Subject Company. Such cooperation shall include the retention and (upon the Other Party’s request) the provision of records and information that are reasonably 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 hereunder.

Section 11.5 Post-Closing Tax Matters. Until the Adjusted Purchase Price is finally determined pursuant to Section 2.7(b), Purchaser shall not (and shall cause its Affiliates (including, after the Closing, the Subject Companies) not to), with respect to any Subject Company for any Tax period (or portion thereof) beginning prior to the Effective Time, (a) file any amended Tax Return, (b) make, change or revoke any Tax election in a manner that is inconsistent with past practice, (c) change any method of accounting with respect to Taxes, (d) initiate any discussion with any Governmental Authority regarding any voluntary disclosure involving Taxes, (e) settle or compromise any Tax liability or (f) surrender any right to claim a refund for Taxes, in each case, without the prior written consent of Sellers’ Representative (such consent not to be unreasonably withheld, conditioned or delayed) to the extent that such action could increase Taxes which Sellers would economically bear hereunder.

Section 11.6 Tax Refunds. Until the Adjusted Purchase Price is finally determined pursuant to Section 2.7(b), Sellers shall be entitled to any and all refunds and credits attributable to Subject Company Group Taxes allocated to Sellers pursuant to Section 11.1, and Purchaser shall be entitled to any and all refunds and credits attributable to Subject Company Group Taxes allocated to Purchaser pursuant to Section 11.1, in each case unless such refunds or credits were taken into account in the final determination of the Adjusted Purchase Price pursuant to Section 2.7(b). If a Party or its Affiliate receives a refund of Subject Company Group Taxes or receives or realizes a Tax benefit attributable to any credit, in each case, to which another Party is entitled pursuant to the first sentence of this Section 11.6, such recipient Party shall forward to the entitled Party the amount of such refund or Tax benefit within thirty (30) days after such refund is received or such Tax benefit is received or realized, as applicable, net of any reasonable costs or expenses incurred by such recipient Party in procuring such refund or Tax benefit.

Section 11.7 Section 280G. Each Subject Company will use commercially reasonable efforts to secure from each Person who is a “disqualified individual” as defined in Section 280G(c) of the Code (each, a “Disqualified Individual”) to whom any payment or benefit is required or proposed to be made in connection with the transactions contemplated by this Agreement that could constitute “parachute payments” under Section 280G(b)(2) of the Code (“Section 280G Payments”) a written agreement waiving such Disqualified Individual’s right to receive some or all of such payment or benefit (the “Waived Benefits”), to the extent necessary so that all remaining payments and benefits applicable to such Disqualified Individual will not be deemed parachute payments, and accepting in substitution for the Waived Benefits the right to receive the Waived Benefits only if approved by the equityholders of such Subject Company in a manner that complies with Section 280G(b)(5)(B) of the Code (the “280G Stockholder Approval”). Prior to the Closing, each Subject Company will submit the Waived Benefits of each Disqualified Individual who has executed a waiver in accordance with this Section 11.7 for approval of such Subject Company’s

139

equityholders and such Disqualified Individual’s right to receive the Waived Benefits will be conditioned upon receipt of the requisite approval by such equityholders in a manner that complies with Section 280G(b)(5)(B) of the Code; provided, in no event will this Section 11.7 be construed to require such Subject Company (or any of its Affiliates) to compel any Disqualified Individual to waive any existing rights under any contract or agreement that such Disqualified Individual has with Sellers, such Subject Company or any other Person, and in no event will such Subject Company (or any of its Affiliates) be deemed in breach of this Section 11.7 if any such Disqualified Individual refuses to waive any such rights or if such equityholders fail to approve any Waived Benefits. Within a reasonable time prior to seeking any waiver of the Waived Benefits and the 280G Stockholder Approval, the Subject Company will provide Purchaser’s counsel with a copy of the waiver agreement, the disclosure statement, equityholder consent and calculations prepared in connection with the actions contemplated by this Section 11.7 and such Subject Company will consider in good faith any changes reasonably requested by Purchaser or its counsel. Prior to the Closing, the Subject Company will deliver to Purchaser notification that either (a) the 280G Stockholder Approval was obtained with respect to the Section 280G Payments or (b) the 280G Stockholder Approval was not obtained with respect to the Section 280G Payments and that, as a consequence, no Waived Benefits will be paid. Notwithstanding the foregoing, to the extent that any contract, agreement, or plan is entered into by Purchaser or any of its Affiliates and a Disqualified Individual in connection with the transactions contemplated by this Agreement before the Closing Date (the “Purchaser Arrangements”), Purchaser shall provide a copy of such contract, agreement or plan to the Subject Company before the Closing Date and shall cooperate with such Subject Company in good faith in order to calculate or determine the value (for the purposes of Section 280G of the Code) of any payments or benefits granted or contemplated therein, that may be paid or granted in connection with the transactions contemplated by this Agreement that could constitute a “parachute payment” under Section 280G of the Code; provided that, in any event, such Subject Company’s failure to include the Purchaser Arrangements in the 280G Stockholder Approval materials described herein, for any reason, will not result in a breach of the covenants set forth in this Section 11.7.

Section 11.8 Push-Out Election. If, after the Closing Date, any member of a Subject Company Group is subject to U.S. federal income tax audit or administrative or judicial proceeding for a Tax period beginning on or prior to the Closing Date resulting in an “imputed underpayment” described in Section 6225 of the Code with respect to such member of such Subject Company Group, then, at Purchaser’s request, the applicable Seller shall timely make (or cause to be timely made) a “push-out” election pursuant to Section 6226 of the Code for such member of such Subject Company Group with respect to such Tax period, unless the Parties unanimously consent in writing to forego such election.

ARTICLE 12

TERMINATION

Section 12.1 Termination. This Agreement may be terminated at any time prior to the Closing (the date of any permitted termination of this Agreement under this Section 12.1, the “Termination Date”):

(a) by the mutual prior written consent of Sellers’ Representative and Purchaser;

140

(b) unless (x) Sellers’ Representative has elected to exercise its rights under Section 12.1(e) or Section 12.2(c) or (y) Purchaser has elected to exercise its rights under Section 12.1(d) or Section 12.2(b) (which election, in each case, shall be made no later than one (1) Business Day following any written Notice of purported termination under this Section 12.1(b)), then by either Sellers’ Representative or Purchaser upon written Notice to the Other Party, if Closing has not occurred on or before June 27, 2023 (the “Initial Outside Date”); provided, however, that if Closing has not occurred on or before such date solely as a result of a failure of the Closing conditions in Section 9.1(e) and Section 9.2(e) to be satisfied, then, without any further action by the Parties, the Initial Outside Date shall be extended to June 30, 2023 for all purposes hereunder; provided, further, that in the event that the Specified Financing Information has not been delivered to Purchaser on or prior to May 15, 2023, the Initial Outside Date shall be automatically extended (but not beyond September 30, 2023) (A) to the fourth (4^th) Business Day following the final day of the Marketing Period or (B) by one calendar day for each calendar day from and including May 15, 2023 to, but excluding, the date the Specified Financing Information is delivered, whichever is earlier; provided that if such date as extended in clause (B) is not a Business Day, the Initial Outside Date shall be automatically extended to the next Business Day (the Initial Outside Date, as extended pursuant to the two immediately preceding provisos, the “Subsequent Outside Date”, it being understood that the Subsequent Outside Date may not be a date after September 30, 2023);

(c) by Sellers’ Representative or Purchaser upon Notice to the Other Party, if a final non-appealable Order has been entered restraining, enjoining or otherwise prohibiting the consummation of the transactions contemplated by this Agreement;

(d) by Purchaser upon written notice to Sellers’ Representative, if no Purchaser Party is then in breach of any provision of this Agreement that would give rise to the failure of any of the conditions specified in Article 9 and there has been a breach, inaccuracy in or failure to perform any representation, warranty, covenant or agreement made by any Seller or any Subject Company pursuant to this Agreement that would give rise to the failure of any of the conditions specified in Article 9 and such breach, inaccuracy or failure cannot be (or has not been) cured by any Seller or Subject Company by the Target Closing Date; or

(e) by Sellers’ Representative upon written notice to Purchaser, if no Seller or Subject Company is then in breach of any provision of this Agreement that would give rise to the failure of any of the conditions specified in Article 9 and there has been a breach, inaccuracy in or failure to perform any representation, warranty, covenant or agreement made by a Purchaser Party pursuant to this Agreement or a failure to obtain the Financing that would give rise to the failure of any of the conditions specified in Article 9 and such breach, inaccuracy or failure cannot be (or has not been) cured by the Purchaser Parties by the Target Closing Date.

(f) by (i) Purchaser if the condition set forth in Section 9.2(d) has not been satisfied on or before the Target Closing Date or (ii) by Sellers’ Representative if the condition set forth in Section 9.1(d) is not satisfied on or before the Target Closing Date; provided that, if either Party notifies the other Party of its intention to terminate this Agreement pursuant to this Section 12.1(f), the non-terminating Party may, prior to giving effect to such termination, elect by written notice (an “Arbitration Notice”) to submit all unresolved disputes with respect to any Disputed Defect Matters, or Casualty Events (mutatis mutandis) to expert arbitration in accordance with Section 3.2(i), for the sole purpose of determining whether the condition in Section 9.2(d) or Section 9.1(d)

141

has been satisfied. In such case, the Parties shall select a Title Referee or Environmental Referee within five (5) Business Days of the delivery of the Arbitration Notice, each Party shall submit such Party’s position to the Title Referee or Environmental Referee, as applicable, within ten (10) Business Days of the delivery of an Arbitration Notice, 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 Event amounts, as applicable, within twenty (20) days after the appointment of such Person. If an Arbitration Notice is delivered, no termination pursuant to this Section 12.1(f) shall be effective (and the Initial Outside Date shall be tolled beginning on the date the Arbitration Notice is delivered to the Party seeking to terminate this Agreement pursuant to Section 12.1(f)) until final resolution of such arbitration; provided that no such extension shall prevent a Party from terminating this Agreement pursuant to the terms hereof if Closing has not occurred, or such final resolution has not been obtained, by June 30, 2023. Nothing herein shall prevent Purchaser from electing to waive or withdraw any asserted Defect at any time prior to termination of this Agreement;

provided, however, that no Party shall be entitled to terminate this Agreement under Section 12.1(b) if (A) the Closing has failed to occur as a result of the breach or failure of any of such Party’s representations, warranties or covenants hereunder that would give rise to the failure of any of the conditions specified in Article 9, including, if and when required, such Party’s obligations to consummate the transactions contemplated hereunder at Closing or (B) a Party is entitled to and is enforcing its right to specific performance of this Agreement under Section 12.2(b) or Section 12.2(c) below.

The Confidentiality Agreement shall survive any termination of this Agreement.

143

required by such Party hereunder, (iii) monetary damages would not be a sufficient remedy for any violation of the terms of this Agreement with respect to each Party’s rights under Section 12.2(b) and Section 12.2(c), (iv) the Other Party shall be entitled to equitable relief, including injunction and specific performance (without the posting of any bond and without proof of actual damages), in the event of any breach of the provisions of this Agreement with respect to each Party’s rights under Section 12.2(b) and Section 12.2(c), (v) neither Party, nor its representatives, shall oppose the granting of specific performance as a remedy with respect to each Party’s rights under Section 12.2(b) and Section 12.2(c) and (vi) each Party agrees to waive any requirement for the security or posting of any bond in connection with the remedies described in Section 12.2(b) and Section 12.2(c).

Section 13.3 Release.

(a) Effective as of immediately prior to the Closing and except to the limited extent set forth in Section 13.1, each Seller, for itself and on behalf of its Affiliates (excluding the Subject Company Groups) and each of their respective equityholders, successors and assigns (the “Seller Releasing Group”) hereby fully and unconditionally releases, acquits and forever discharges the Purchaser Group, each Subject Company Group, each of their respective direct and indirect equityholders, and its and their Representatives in their capacity as such, and each of their respective successors and assigns from any and all manner of actions, causes of actions, claims obligations, demands, damages, costs, expenses, compensation or other relief, whether known or unknown, whether in Law or equity, of any kind, that any member of the Seller Releasing Group now has or has ever had against the members of the Subject Company Group, in respect of or arising out the ownership, operation, management, administration or use of the Subject Company Groups, the Subject Securities or the Assets prior to Closing (including with respect to any matters pertaining to the Seller Reorganization, and any Affiliate Arrangement incident thereto); provided, however, the foregoing notwithstanding, the release and discharge provided for herein shall not release (i) the members of any Subject Company Group of their respective obligations or liabilities, if any, pursuant to this Agreement or the Transaction Documents, (ii) the members of any Subject Company Group of any indemnification or exculpation obligations of such Person to Sellers as a

145

Seller hereby irrevocably covenants to refrain from, directly or indirectly (and shall cause each member of the Seller Release Group to refrain from), asserting any claim released pursuant to the foregoing provisions of this Section 13.3(a), or commencing, instituting or causing to be commenced, any proceeding of any kind against any of the released Persons set forth in the first sentence of this Section 13.3(a) in their capacity as such, with respect to any such claim. Each Seller hereby represents to Purchaser that it has not assigned or transferred or purported to assign or transfer to any Person all or any part of, or any interest in, any such claim.

(b) Effective as of immediately prior to the Closing, each Subject Company, for itself and on behalf of its Subsidiaries and each of their respective equityholders, successors and assigns (the “Subject Company Releasing Group”) hereby fully and unconditionally releases, acquits and forever discharges (i) Sellers and (ii) all directors, managers, officers and agents of such Subject Company and its Subsidiaries holding such position at any time prior to the Closing in their capacity as such from any and all manner of actions, causes of actions, claims, obligations, demands, damages, costs, expenses, compensation or other relief, whether known or unknown, whether in Law or equity, of any kind, that any member of the Subject Company Releasing Group now has or has ever had against such Persons, arising out of or relating to (A) in respect of Sellers and their direct and indirect equityholders, Sellers’ ownership of the Subject Securities, and (B) in respect of such directors, managers, officers and agents, for acts and omissions on behalf of such Subject Company or its Subsidiaries or the relationship with such Subject Company or its Subsidiaries, in each case, other than with respect to their respective obligations and liabilities, if any, under this Agreement or the Transaction Documents. The foregoing notwithstanding, the release and discharge provided for herein shall not release any Seller or its Affiliates from any obligations, liabilities, claims, causes of action and Damages directly arising from or relating to the Seller Reorganization, the ownership, operation or business of any Excluded Subsidiaries, or any Excluded Assets. Purchaser, for itself and, following the Closing, on behalf of each Subject Company Group hereby irrevocably covenants to refrain from, directly or indirectly (and shall cause each member of the Subject Company Releasing Group to refrain from), asserting any claim released pursuant to the foregoing provisions of this Section 13.3(b), or commencing, instituting or causing to be commenced, any proceeding of any kind against any of the released Persons set forth in the first sentence of this Section 13.3(b) in their capacity as such, with respect to any such claim.

Notwithstanding anything to the contrary contained in this Agreement (but subject to and without limiting the last sentence of this Section 13.4), from and after Closing, except in respect of claims of Fraud, Purchaser’s and Purchaser Group’s sole and exclusive remedy against any member of the Seller Group with respect to the Assets, the Business, the Subject Securities, Subject Company Groups, 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, and the affirmations of such representations, warranties, covenants and agreements contained in the Closing Certificate are (a) the rights to the proceeds of the R&W

146

Insurance Policy, (b) the rights set forth in Section 3.2(i) with respect to disputed Defects and(c) the right to seek specific performance for the breach or failure of a Seller to perform any covenants required to be performed after Closing. Upon Closing, absent Fraud, each Purchaser Party waives, releases, remises and forever discharges, and shall cause each member of the Purchaser Group to waive, release, remise and forever discharge, each member of the Seller Group from any and all Damages, suits, legal or administrative Actions, claims, demands, losses, costs, obligations, liabilities, interest, charges or causes of action whatsoever, in Law or in equity, known or unknown, which any member of the Purchaser Group might now or subsequently may have, based on, relating to or arising out of the Assets, the Business, the Subject Securities, Subject Company Groups, the negotiation, performance and consummation of this Agreement or the other Transaction Documents or the transactions contemplated hereunder or thereunder, or any member of the Seller Group’s ownership, use or operation of the Assets, or the condition, quality, status or nature of any Assets, or any actions taken by managers or officers of any Subject Company prior to the Closing Date, INCLUDING RIGHTS TO CONTRIBUTION UNDER CERCLA OR ANY OTHER ENVIRONMENTAL LAW, BREACHES OF STATUTORY AND IMPLIED WARRANTIES, NUISANCE OR OTHER TORT ACTIONS, RIGHTS TO PUNITIVE DAMAGES, COMMON LAW RIGHTS OF CONTRIBUTION, ANY RIGHTS UNDER INSURANCE POLICIES ISSUED OR UNDERWRITTEN BY ANY MEMBER OF THE PURCHASER GROUP AND ANY RIGHTS UNDER AGREEMENTS AMONG ANY MEMBERS OF THE SELLER GROUP, EVEN IF CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER GROSS, SOLE, JOINT, ACTIVE, PASSIVE, COMPARATIVE OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY RELEASED PERSON, INVITEES OR THIRD PARTIES. Nothing in this Section 13.4 shall be construed to waive or release any member of the Seller Group from its obligations or liabilities to the extent set forth under the Escrow Agreement or the resignations and releases delivered pursuant to Section 10.2(h).

Section 13.5 Indemnification Actions. All claims for indemnification under this Article 13 shall be asserted and resolved as follows:

(a) For purposes of this Article 13, the term “Indemnifying Party” when used in connection with particular Damages means the Party having an obligation to indemnify any member of the Seller Group with respect to such Damages pursuant to this Article 13, and the term “Indemnified Person” when used in connection with particular Damages shall mean the Party and/or other Persons having the right to be indemnified with respect to such Damages by the Indemnifying Party pursuant to Article 13.

(b) To make a claim for indemnification, defense or reimbursement under this Article 13, an Indemnified Person shall notify the Indemnifying Party of its claim, including the specific details 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

147

this Article 13 shall not relieve the Indemnifying Party of its obligations under this Article 13 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 materially prejudices the Indemnifying Party’s ability to defend against the Third Party Claim.

(d) 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 the Indemnifying Party’s 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 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.

(e) If the Indemnifying Party admits its obligation to defend the Indemnified Person against such Third Party Claim under this Agreement, then the applicable Indemnifying Party shall have (i) the right and obligation to diligently prosecute and control the defense of such Third Party Claim at its sole cost and expense, and (ii) have full control of such defense and proceedings, including any compromise or settlement thereof unless the compromise or settlement does not comply with the last sentence of this subsection (e), in which event such settlement or compromise shall not be effective without the consent of the Indemnified Person, which shall be withheld or delayed in the Indemnified Person’s sole discretion. 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 13.5(e), provided that the Indemnified Person may file initial pleadings as described in the last sentence of subsection (d) above if required by court or procedural rules to do so within the thirty (30) day period in subsection (d) above. 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 an Indemnifying Party does not admit 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

148

Party Claim (at the sole cost and expense of the Indemnifying Party if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing, subject to the right of the Indemnifying Party to admit its obligation to defend the Indemnified Person against such Third Party Claim under this Agreement at any time prior to settlement or final determination thereof. If an Indemnifying Party has not yet admitted an Indemnified Person’s right to indemnity and reimbursement right against such Third Party Claim as provided in this Article 13, 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 admit its obligation to defend the Indemnified Person against such Third Party Claim under this Agreement, as applicable, and 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.

Section 13.6 Express Negligence/Conspicuous Manner. WITH RESPECT TO THIS AGREEMENT, THE PARTIES AGREE THAT THE PROVISIONS SET OUT IN THIS ARTICLE 13 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 (AND EACH SUBJECT COMPANY FROM AND AFTER CLOSING) 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.

Section 14.3 Venue and Waiver of Jury Trial.

Each Party agrees that any and all process directed to it in any such Action may be served upon it outside of the State of Texas in and for Harris County United States District Court or the Texas State District Court located in Houston, Texas with the same force and effect as if such service had been made within the State of Texas in and for Harris County or the United States District Court or the Texas State District Court located in Houston, Texas.

Section 14.4 Headings and Construction. The headings and captions herein are inserted for convenience of reference only and are not intended to govern, limit or aid in the construction of any term or provision hereof. The rights and obligations of each Party shall be determined pursuant to this Agreement. Each Party has 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.

152

Section 14.5 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. No consent under this Agreement shall be valid unless set forth in an instrument in writing signed on behalf of such Party.

Section 14.6 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 14.7 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 Purchaser, each Seller and each Subject Company, and any transfer or delegation made without such consent shall be null and void ab initio; provided that nothing in this Section 14.7 shall limit the ability of Purchaser to assign its rights to the R&W Insurer under the R&W Insurance Policy pursuant to the subrogation provisions thereof. Unless expressly agreed to in writing by Purchaser, each Seller and each Subject Company, no permitted assignment of any Party’s rights or duties that is subject to the consent of Purchaser, each Seller and each Subject Company 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 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 14.8 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.

Parent agrees that the Parent Guarantee is a primary obligation of Parent and that Sellers, the Subject Companies and/or their Representatives may enforce the Parent Guarantee without the necessity at any time of resorting to or exhausting any other security or collateral. This is a guarantee of payment when and as due and not merely of collection. Parent agrees that the guarantee set forth in this Section 14.15 shall not be discharged except by the complete and irrevocable performance of all Guaranteed Obligations or the earlier consummation of the Closing of the transactions contemplated by this Agreement. Parent reserves the right to assert any and all defenses which Purchaser may assert against Sellers under this Agreement with respect to payment or performance of any Guaranteed Obligation. Parent hereby expressly waives diligence, presentment, protest and all notices whatsoever and any requirement that Sellers exhaust any right, power or remedy or proceed against Purchaser under this Agreement or any other agreement or instrument referred to herein or therein.

156

Section 14.16 Certain Waivers. Purchaser agrees, on its own behalf and on behalf of the other Purchaser Group (including the Subject Company Groups following Closing), that, following the Closing, Vinson & Elkins LLP may serve as counsel to any Seller and its Affiliates in connection with any matters related to this Agreement and the transactions contemplated hereby, including any dispute arising out of or relating to this Agreement and the transactions contemplated hereby, notwithstanding any representation by Vinson & Elkins LLP of any Subject Company prior to the Closing Date. Purchaser, on behalf of itself and the other members of the Purchaser Group (including the Subject Company Groups after the Closing) hereby (a) consents to Vinson & Elkins LLP’s representation of any Seller or its Affiliates in connection with any matters related to this Agreement and the transactions contemplated hereby (the “Subject Representation”), (b) waives any claim it has or may have that Vinson & Elkins LLP has a conflict of interest or is otherwise prohibited from engaging in such Subject Representation based on its representation of the Subject Company Groups prior to the Closing and (c) agrees that, in the event that a dispute arises between Purchaser, any Subject Company or any of their respective Affiliates, on the one hand, and any Seller and/or its Affiliates, on the other hand, none of Purchaser, any Subject Company or any of their respective Affiliates will object to Vinson & Elkins LLP representing any Seller and/or its Affiliates in such dispute due to the interests of any Seller and its Affiliates being directly adverse to Purchaser, any Subject Company or any of their respective Affiliates or due to Vinson & Elkins LLP having represented any Subject Company in a matter substantially related to such dispute. Purchaser further agrees that, as to all communications among Vinson & Elkins LLP, any Subject Company, any Seller or their respective Affiliates and Representatives prior to the Closing that relate to the Subject Representation, the attorney-client privilege belongs, to the extent such privilege exists, to Seller and its Affiliates and may be controlled by any Seller and each of its Affiliates and will not, with respect to such privileged communications, pass to or be claimed by Purchaser, any Subject Company or any of their respective Affiliates. To the extent that Purchaser, any Subject Company or any of their respective Affiliates has or maintains any ownership of the privilege with respect to these communications, they agree, except as may be required by applicable Law, not to waive or to attempt to waive the privilege without the express written approval of the applicable Seller. Notwithstanding the foregoing, in the event that a dispute arises between Purchaser, any Subject Company and a Third Party (other than a Seller and its Affiliates) or any Governmental Authority after the Closing, any Subject Company may assert the attorney-client privilege against such Third Party to prevent disclosure of confidential communications by or with Vinson & Elkins LLP.

Section 14.17 Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Facsimile, .pdf or other electronic transmission of copies of signatures shall constitute original signatures for all purposes of this Agreement and any enforcement hereof.

Section 14.18 Concerning Financing Sources. Notwithstanding anything in this Agreement to the contrary, each Party hereby:

(a) agrees that any Action, whether in law or in equity, whether in contract or in tort or otherwise, against any Financing Source Related Party in any way arising out of or relating to this Agreement, the Debt Commitment Papers, the definitive agreements relating to the Financing, the Financing or any of the other transactions contemplated hereby or thereby (any such Action being referred to as the “Financing Sources Action”) shall be subject to the exclusive jurisdiction of any state or federal court sitting in the Borough of Manhattan in the City of New York (or any appellate court therefrom), and agrees not to bring or support, or permit any of its Affiliates to bring or support, any Financing Sources Action in any forum other than in any such court;

157

(b) irrevocably and unconditionally submits, for itself and its property, with respect to any Financing Sources Action to the jurisdiction of any such court;

(c) irrevocably and unconditionally waives any objection to the laying of venue of any Financing Sources Action brought in any such court or any claim that any Financing Sources Action brought in any such court has been brought in an inconvenient forum;

(d) agrees that services on any Party hereto may be made by sending or delivering a copy of the process to the Party to be served at the address and in the manner provided for the giving of notices in Section 14.1;

(e) agrees that any Financing Sources Action shall be governed by the laws of the State of New York (without giving effect to any conflicts of law principles that would result in the application of the laws of another state), except as otherwise expressly provided in the Debt Commitment Papers or the definitive agreements relating to the Financing; provided, however, that notwithstanding the foregoing, it is understood and agreed that interpretation of the provisions of this Agreement (including with respect to satisfaction of the conditions contained herein, whether the acquisition has been consummated as contemplated by this Agreement, any alleged “Seller Material Adverse Effect” and any determination of whether a “Seller Material Adverse Effect” has occurred (or would reasonably be expected to occur) and whether the representations and warranties made by or on behalf of any Subject Company in this Agreement (including any “Acquisition Agreement Representations” or similar term contained in the Debt Commitment Papers) are accurate and whether as a result of any inaccuracy thereof Parent (or its applicable affiliate) has, under the express terms of this Agreement, the right (taking into account any applicable cure provisions) to terminate its obligations under this Agreement, or the right not to consummate the Transactions pursuant to this Agreement (in each case, without giving effect to notice or lapse of time or both), as a result of any inaccuracy of such representations or warranties in this Agreement, in each case, in accordance with the terms thereof) and all issues and questions concerning the construction, validity, interpretation and enforceability of this Agreement and the exhibits and schedules hereto shall be governed by, and construed in accordance with, the laws of the State of Texas without giving effect to the principles of conflicts of law that would result in the application of the law of any other state; provided that in connection with the determination of the existence of any Environmental Defect, the federal Laws of the United States and the Laws of the State of Texas shall govern and control such determination;

(f) expressly and irrevocably waives its right to a jury trial with respect to any Financing Sources Action;

(g) agrees that none of the Financing Sources Related Parties will have any obligation or liability, on any theory of liability, to any of the Sellers, the Subject Companies, the Sellers’ Representative or their respective Affiliates, and none of the Sellers, the Subject Companies, the Sellers’ Representative or their respective Affiliates shall have any rights or claims against any of the Financing Sources Related Parties, in each case, in any way arising out of or relating to this Agreement, the Debt Commitment Papers, the definitive agreements relating to the Financing, the Financing or any of the other transactions contemplated hereby or thereby, whether in law or in equity, whether in contract or in tort or otherwise; provided that following consummation of the Closing, the foregoing will not limit the rights of the parties to the Financing under any definitive agreements relating thereto;

(h) agrees that, notwithstanding anything to the contrary in this Agreement or any document entered into in connection with this Agreement, the Financing Sources are express third party beneficiaries of, and may enforce, this Section 14.18; and

(i) agrees that the provisions in this Section 14.18 (and any definition set forth in, or any other provision of, this Agreement to the extent that an amendment, waiver or other modification of such definition or other provision would amend, waive or otherwise modify the substance of this Section 14.18) shall not be amended, waived or otherwise modified, in each case, in any way adverse to the Financing Sources Related Parties without the prior written consent of the Financing Sources (and any such amendment, waiver or other modification without such prior written consent shall be null and void).

If the Shelf Registration Statement does not qualify as an ASR Filing, the Company shall use its commercially reasonable efforts to cause such Registration Statement to become or be declared effective as soon as practicable after the filing thereof and, in any event, within thirty (30) days after the filing thereof in the case of a Shelf Registration Statement on Form S-3 that is not an ASR Filing or, if Form S-3 is not then available, within forty-five (45) days after the filing thereof in the case of a Shelf Registration Statement on Form S-1 (or, in the case of either a Form S-3 that is not an ASR Filing or Form S-1, within sixty (60) days after the filing thereof if the SEC notifies the Company that it will “review” the Shelf Registration Statement; provided that, the Company will promptly respond to any and all comments received from the SEC, with a view towards causing such Shelf Registration Statement or any amendment thereto to be declared effective by the SEC as soon as practicable and shall file an acceleration request promptly following the resolution or clearance of all SEC comments). Following the effective date of the Shelf Registration Statement that is not an ASR Filing, the Company shall notify the Holders of the effectiveness of such Shelf Registration Statement. The plan of distribution indicated in the Shelf Registration Statement will include all such methods of sale as any Holder may reasonably request in writing at least five Business Days prior to the filing of the Shelf Registration Statement and that can be included in the Shelf Registration Statement under the rules and regulations of the SEC. Until such time as all Registrable Securities cease to be Registrable Securities, the Company is no longer eligible to maintain a Shelf Registration Statement, or the provisions of this Agreement terminate in accordance with Section 3.1, the Company shall use its reasonable best efforts to keep current and effective such Shelf Registration Statement and file such supplements or amendments to such Shelf Registration Statement (or file a new Shelf Registration Statement (which Shelf Registration Statement shall be an Automatic

4

Shelf Registration Statement if the Company is then eligible to file an Automatic Shelf Registration Statement) when such preceding Shelf Registration Statement expires pursuant to the rules of the SEC) as may be necessary or appropriate to keep such Shelf Registration Statement continuously effective and useable for the resale of all Registrable Securities under the Securities Act. Any Shelf Registration Statement when declared effective (including the documents incorporated therein by reference) will comply in all material respects as to form with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

(b) Any one or more Holders of Registrable Securities may request to sell all or any portion of their Registrable Securities in an underwritten offering that is registered pursuant to the Shelf Registration Statement (each, an “Underwritten Shelf Takedown”); provided, however, that the Holders, in the aggregate, will be entitled to make a demand (a “Demand Request”) for a total of only three Underwritten Shelf Takedowns in the aggregate and no more than two of such three Underwritten Shelf Takedowns during any 12-month period, and only if the proceeds from the sale of Registrable Securities in any such Underwritten Shelf Takedown (before the deduction of underwriting discounts) is reasonably expected to exceed, in the aggregate, $200 million. At the request of such Holders, the plan of distribution for the Underwritten Shelf Takedowns shall include a customary “road show” (including an “electronic road show”) or other substantial marketing effort by the Company and the underwriters over a period not to exceed 24 hours (a “Marketed Underwritten Shelf Takedown”). Subject to the other limitations contained in this Agreement, the Company shall not be obligated hereunder to effect an Underwritten Shelf Takedown within 90 days after the closing of an Underwritten Shelf Takedown. If an Underwritten Shelf Takedown is not a Marketed Underwritten Shelf Takedown, the Company and its management will not be required to participate in a roadshow or other marketing effort. For the avoidance of doubt, an Underwritten Shelf Takedown shall not include an “at the market” program.

(c) The Demand Request for an Underwritten Shelf Takedown shall be made by the Holder or Holders making such request (the “Requesting Holder”) by giving written notice to the Company. The Demand Request shall specify the approximate number of Registrable Securities to be sold in such Underwritten Shelf Takedown and the expected price range of securities to be sold in such Underwritten Shelf Takedown. Within three Business Days (or one Business Day if the Demand Request is for an Overnight Underwritten Offering, Same-Day Offering or similar “bought deal”) after receipt of any Demand Request, the Company shall send written notice of such requested Underwritten Shelf Takedown to all other Holders of Registrable Securities (the “Company Notice”) and shall include in such Underwritten Shelf Takedown all Registrable Securities with respect to which the Company has received written requests for inclusion therein within five Business Days (or one Business Day if the Demand Request is for an Overnight Underwritten Offering, Same-Day Offering or similar “bought deal”) after sending the Company Notice.

(d) The Company shall propose four or more nationally prominent firms of investment bankers reasonably acceptable to the Requesting Holder(s) to act as the managing underwriter or as other underwriters in connection with such Underwritten Shelf Takedown, from which the Participating Majority shall select the managing underwriter and the other underwriters.. The “Participating Majority” shall mean, with respect to an Underwritten Shelf Takedown, the Holder(s) of a majority of the Registrable Securities requested to be included in such Underwritten Shelf Takedown. All Holders proposing to distribute their securities through such underwriting shall enter into a customary underwriting agreement with such underwriter or underwriters in accordance with Section 2.1(g). The Company will use its reasonable best efforts to cause members of senior management to cooperate with the underwriter(s) in connection with an Underwritten Shelf Takedown and make themselves available to participate in the marketing process in connection with such Underwritten Shelf Takedown as requested by the managing underwriter(s) and providing such additional information reasonably requested by the managing underwriter(s) (in addition to the minimum information required by law, rule or regulation) in any prospectus relating to an Underwritten Shelf Takedown.

(e) If the managing underwriter(s) for an Underwritten Shelf Takedown advise the Company and the participating Holders in writing that, in their opinion, marketing factors require a limitation of the amount of securities to be underwritten (including Registrable Securities) because the amount of securities to be underwritten is likely to have an adverse effect on the marketability of the offering, then the Company shall so advise all Holders of Registrable Securities which would otherwise be underwritten pursuant hereto, and the amount of Registrable Securities that may be included in the underwriting shall be allocated among the participating Holders, (i) first among the participating Holders as nearly as possible on a pro rata basis based on the total amount of Registrable Securities

5

held by such Holders requested to be included in such underwriting and (ii) second to the extent all Registrable Securities requested to be included in such underwriting by the participating Holders have been included, to any other Persons pursuant to contractual registration rights as nearly as possible on a pro rata basis based on the total amount of Registrable Securities (as defined in the contractual registration rights) held by such other Persons requested to be included in such underwriting. The Company shall prepare preliminary and final prospectus supplements for use in connection with the Underwritten Shelf Takedown, containing such additional information as may be reasonably requested by the underwriter(s).

(f) Upon written notice to the Holders of Registrable Securities, the Company shall be entitled to suspend, for a period of time not to exceed the periods specified in Section 2.2(u) (each, a “Suspension Period”), the use of any Registration Statement or Prospectus and shall not be required to amend or supplement the Registration Statement, any related Prospectus or any document incorporated therein by reference if: (i) the Company receives any request by the SEC or any other federal or state governmental authority for amendments or supplements to such Registration Statement or Prospectus or for additional information that pertains to such Holders as sellers of Registrable Securities; (ii) the SEC issues any stop order suspending the effectiveness of the Registration Statement covering any or all of the Registrable Securities or the initiation of any proceedings for that purpose; (iii) the Company receives any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any United States jurisdiction, or the initiation or threatening of any proceeding for such purpose; or (iv) the board of directors, President & Chief Executive Officer or Executive Vice President & Chief Financial Officer of the Company determines in its reasonable good faith judgment that the Registration Statement contains an untrue statement of a material fact or omits any fact required to be stated therein or necessary to make the statements in the Registration Statement not misleading or that any Prospectus includes an untrue statement of a material fact or omits any fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, that the Company shall use its good faith efforts to amend the Registration Statement or Prospectus to correct such untrue statement or omission as promptly as reasonably practicable, unless the board of directors, President & Chief Executive Officer or Executive Vice President & Chief Financial Officer of the Company determines in good faith that such amendment would reasonably be expected to have a materially detrimental effect on the Company. The Holders acknowledge and agree that written notice of any Suspension Period may constitute material non-public information regarding the Company and shall keep the existence and contents of any such written notice confidential.

(g) If requested by the managing underwriter(s) for an Underwritten Shelf Takedown, the Company shall enter into an underwriting agreement with the underwriters for such offering, such agreement to be in form and substance (including with respect to representations and warranties by the Company) as is customarily given by the Company to underwriters in an underwritten public offering, and to contain indemnities generally to the effect and to the extent provided in Section 2.7. The Holders of Registrable Securities participating in such Underwritten Shelf Takedown shall be parties to such underwriting agreement and shall be required to make customary representations and warranties, in each case subject to the reasonable and customary requirements of the managing underwriter(s), in connection with any such registration or transfer. No Holder may participate in an Underwritten Shelf Takedown unless such Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, beneficial ownership information, powers of attorney, customary indemnities and other documents reasonably required by the managing underwriter(s) under the terms of such underwriting agreement. Each participating Holder may, at its option, require that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations.

(h) Each of the Holders hereby agrees (a) to cooperate with the Company and to furnish to the Company all such information regarding such Holder, its ownership of Registrable Securities and the disposition of such securities in connection with the preparation of the Registration Statement and any filings with any state securities commission as the Company may reasonably request, (b) to the extent required by the Securities Act, to deliver or cause delivery of the Prospectus contained in the Registration Statement, any amendment or supplement thereto, to any purchaser of Registrable Securities covered by the Registration Statement from the Holder and (c) if reasonably requested by the Company, to notify the Company of any sale of Registrable Securities by such Holder.

2.2 Registration Procedures. In connection with the registration and sale of Registrable Securities pursuant to this Agreement, the Company will use its reasonable best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto the Company will:

6

(e) furnish to the selling Holders such numbers of copies of such Registration Statement, each amendment and supplement thereto, each Prospectus (including each preliminary Prospectus and Prospectus supplement) and such other documents as the Holder and any underwriter(s) may reasonably request in order to facilitate the disposition of the Registrable Securities;

(f) use its reasonable best efforts to register and qualify the Registrable Securities under such other securities or blue-sky laws of such jurisdictions in the United States as shall be reasonably requested by the Holders and any underwriter(s) and do any and all other acts and things that may be reasonably necessary or advisable to enable the Holders and any underwriter(s) to consummate the disposition of the Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business in or to file a general consent to service of process in any jurisdiction, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act, or subject itself to taxation in any such jurisdiction, unless the Company is already subject to taxation in such jurisdiction;

(g) use its reasonable best efforts to cause all such Registrable Securities to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar equity securities issued by the Company are then listed;

(h) enter into such customary agreements and take such other actions as the Holders shall reasonably request in order to expedite or facilitate the disposition of the Registrable Securities (including, in the case of a Underwritten Shelf Takedown or Piggyback Underwritten Offering, to agree, and to cause its directors and “executive officers” (as defined under Section 16 of the Exchange Act) to agree, to such “lock-up” arrangements with the underwriters thereof to the extent reasonably requested by the managing underwriters(s), subject to exceptions for permitted sales by directors and executive officers during such period consistent with underwritten offerings previously conducted by the Company);

(i) provide a transfer agent and registrar for the Registrable Securities and provide a CUSIP number for all such Registrable Securities, in each case not later than the effective date of the Registration Statement;

(j) use its reasonable best efforts to furnish, on the date that shares of Registrable Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters, (i) an opinion, dated as of such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters by the Company in an underwritten public offering, addressed to the underwriters, (ii) a letter dated as of such date, from the independent public accountants of the Company, in form and substance as is customarily given by independent public accountants to underwriters in an underwritten public offering, addressed to the underwriters and (iii) an engineers’ reserve report letter as of such date, from the independent petroleum engineers of the Company, in form and substance as is customarily given by independent petroleum engineers to underwriters in an underwritten public offering, addressed to the underwriters;

(k) if requested by the Holders, cooperate with the Holders and the managing underwriter(s) (if any) to facilitate the timely preparation and delivery of certificates (which shall not bear any restrictive legends unless required under applicable law) representing securities sold under the Registration Statement, and enable such securities to be in such denominations and registered in such names as such Holders or the managing underwriter (if any) may request and keep available and make available to the Company’s transfer agent prior to the effectiveness of such Registration Statement a supply of such certificates;

7

(l) in the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in form and substance as is customarily given by the Company to underwriters in an underwritten public offering, with the underwriter(s) of such offering;

(m) upon execution of confidentiality agreements in form and substance reasonably satisfactory to the Company, promptly make available for inspection by the selling Holders, any underwriter(s) participating in any disposition pursuant to such Registration Statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the selling Holders, all financial and other records, pertinent corporate documents, and properties of the Company reasonably requested (collectively, “Records”), and use reasonable best efforts to cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant, or agent, in each case, as necessary or advisable to verify the accuracy of the information in such Registration Statement and to conduct appropriate due diligence in connection therewith; provided, that Records that the Company determines, in good faith, to be confidential and that it notifies the selling Holders are confidential shall not be disclosed by the selling Holders unless the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction or is otherwise required by applicable law. Each Holder agrees that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it or its affiliates (other than with respect to such Holders’ due diligence) unless and until such information is made generally available to the public, and further agrees that, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, to the extent permitted and to the extent practicable it shall give notice to the Company and allow the Company to undertake appropriate action to prevent disclosure of the Records deemed confidential;

(n) promptly notify the selling Holders and any underwriter(s) of the notification to the Company by the SEC of its initiation of any proceeding with respect to the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement, and in the event of the issuance of any stop order suspending the effectiveness of such Registration Statement, or of any order suspending or preventing the use of any related Prospectus or suspending the qualification of any Registrable Securities included in such Registration Statement for sale in any jurisdiction, use its reasonable best efforts to obtain promptly the withdrawal of such order;

(o) promptly notify the selling Holders and any underwriter(s) at any time when a Prospectus relating thereto is required to be delivered under the Securities Act of the occurrence of any event as a result of which the Prospectus included in the Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein not misleading in light of the circumstances under which they were made, and at the request of any Holder promptly prepare and furnish to such Holder a reasonable number of copies of a supplement to or an amendment of such Prospectus, or a revised Prospectus, as may be necessary so that, as thereafter delivered to the purchasers of such securities, such Prospectus shall not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in light of the circumstances under which they were made (following receipt of any supplement or amendment to any Prospectus, the selling Holders shall deliver such amended, supplemented or revised Prospectus in connection with any offers or sales of Registrable Securities, and shall not deliver or use any Prospectus not so supplemented, amended or revised);

(p) promptly notify the selling Holders and any underwriter(s) of the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction;

(q) make available to each Holder (i) promptly after the same is prepared and publicly distributed, filed with the SEC, or received by the Company, one copy of each Registration Statement and any amendment thereto, each preliminary Prospectus and Prospectus and each amendment or supplement thereto, each letter written by or on behalf of the Company to the SEC or the staff of the SEC (or other governmental agency or self-regulatory body or other body having jurisdiction, including any domestic or foreign securities exchange), and each item of correspondence from the SEC or the staff of the SEC (or other governmental agency or self-regulatory body or other body having jurisdiction, including any domestic or foreign securities exchange), in each case relating to such Registration Statement, and (ii) such number of copies of each Prospectus, including a preliminary Prospectus, and all amendments and supplements thereto and such other documents as any Holder or any underwriter may reasonably request in order to facilitate the disposition of the Registrable Securities. The Company will promptly

8

notify the Holders of the effectiveness of each Registration Statement or any post-effective amendment or the filing of any supplement or amendment to such Registration Statement or of any Prospectus supplement. The Company will promptly respond to any and all comments received from the SEC, with a view towards causing each Registration Statement or any amendment thereto to be declared effective by the SEC as soon as practicable and shall file an acceleration request, if necessary, as soon as practicable following the resolution or clearance of all SEC comments or, if applicable, following notification by the SEC that any such Registration Statement or any amendment thereto will not be subject to review;

(r) take no direct or indirect action prohibited by Regulation M under the Exchange Act; provided, that, to the extent that any prohibition is applicable to the Company, the Company will take all reasonable action to make any such prohibition inapplicable;

(s) until the date that is six months following the date of this Agreement, in connection with any transaction or series of anticipated transactions (i) effected pursuant to the Shelf Registration Statement, (ii) with reasonably anticipated gross proceeds in excess of $75 million or involving Registrable Securities having a fair market value in excess of $75 million and (iii) involving a broker, agent, counterparty, underwriter, bank or other financial institution (a “Financial Counterparty,” it being understood for avoidance of doubt that any Holder shall have the sole and exclusive right to engage any such Financial Counterparty), to the extent reasonably requested by the Financial Counterparty in order to engage in the proposed transaction, the Company will use its commercially reasonable efforts to cooperate with such Holder in allowing the Financial Counterparty to conduct customary “underwriter’s due diligence” with respect to the Company;

(t) take such other actions as are reasonably necessary in order to facilitate the disposition of such Registrable Securities; and

(u) notwithstanding any other provision of this Agreement, the Company shall not be required to file a Registration Statement or any amendment thereto (other than the initial filing of the Shelf Registration Statement by the Shelf Filing Deadline as contemplated by Section 2.1(a) of this Agreement and any pre-effective amendment thereto) or effect a requested Underwritten Shelf Takedown (or, if the Company has filed a Shelf Registration Statement and has included Registrable Securities therein, the Company shall be entitled to suspend the offer and sale of Registrable Securities pursuant to such Registration Statement) for a period of up to 60 days (or 30 days during the first six months following the date of this Agreement) if (i) the board of directors determines that a postponement is in the best interest of the Company and its stockholders generally due to a proposed transaction involving the Company and determines in good faith that the Company’s ability to pursue or consummate such a transaction would be materially and adversely affected by any required disclosure of such transaction in the Shelf Registration Statement, (ii) the board of directors determines such registration would render the Company unable to comply with applicable securities laws or (iii) the board of directors determines such registration would require disclosure of material information that the Company has a bona fide business purpose for preserving as confidential (any such period, a “Blackout Period”); provided, however, that in no event shall any Blackout Period and/or Suspension Period collectively exceed an aggregate of (i) 30 days in the six-month period following the date of this Agreement or (ii) 120 days in any 12-month period. For the purposes of calculating the number of days of one or more Blackout Periods under this Section 2.2(u) (or Suspension Periods pursuant to Section 2.1(f)), such number shall include any number of days during the applicable period during which the Holders were obligated to discontinue their disposition of Registrable Securities pursuant to Section 2.1(f) and/or 2.3(f) of this Agreement.

2.3 Suspension of Dispositions. Each Holder agrees by acquisition of any Registrable Securities that, upon receipt of any notice (a “Suspension Notice”) from the Company of the occurrence of any event of the kind described in Section 2.2(c), Section 2.2(m), Section 2.2(n), Section 2.2(o) or Section 2.2(s), such Holder will forthwith discontinue disposition of Registrable Securities pursuant to the Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus, or until it is advised in writing (the “Advice”) by the Company that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings which are incorporated by reference in the Prospectus. The Company shall extend the period of time during which the Company is required to maintain the Registration Statement effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of such Suspension Notice to and including the date such Holder either receives the supplemented or amended Prospectus or receives the Advice. If so directed by the Company, such Holder will deliver to the Company all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities current at the time of receipt of such notice. The Company shall use its reasonable best efforts and take such actions as are reasonably necessary to

9

render the Advice as promptly as practicable. The Holders acknowledge and agree that receipt of a Suspension Notice may constitute material non-public information regarding the Company and shall keep the existence and contents of any such Suspension Notice confidential. Any Underwritten Shelf Takedown which is suspended because of a Suspension Notice shall not be deemed to be a Demand Request for purposes of Section 2.1(b) unless and until a suspension pursuant to this Section 2.3 is concluded and such Underwritten Shelf Takedown is completed.

2.4 Registration Expenses. All Registration Expenses shall be borne by the Company. In addition, for the avoidance of doubt, the Company shall pay its internal expenses in connection with the performance of or compliance with this Agreement (including all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on which they are to be listed. All Selling Expenses relating to Registrable Securities registered shall be borne by the Holders of such Registrable Securities pro rata on the basis of the number of Registrable Securities sold.

2.5 Initial Lock-Up Period. Each Initial Holder agrees that, during the period beginning on the date of this Agreement and ending on the 90^th day thereafter (the “Lock-Up Period”), such Initial Holder will not offer, sell, contract to sell, pledge, grant any option to purchase, lend or otherwise dispose of the shares of Common Stock issued to such Initial Holder pursuant to the Purchase Agreement; provided, however, that the transfer of Common Stock by an Initial Holder is permitted (i) to Permitted Transferees who shall (A) be subject to the restrictions in this Section 2.5 as if they were the original holders of such Common Stock and (B) promptly transfer such Common Stock back to the applicable Initial Holder if they cease to be a Permitted Transferee for any reason prior to the expiration of the Lock-Up Period, (ii) to other Initial Holders and their Affiliates, (iii) pursuant to a court order or settlement agreement, and (iv) pursuant to a bona fide third-party tender offer, merger, stock sale, recapitalization, consolidation or other transaction involving a Change in Control of the Company (provided, however, that in the event that such tender offer, merger, recapitalization, consolidation or other such transaction is not completed, the Common Stock subject to this Agreement shall remain subject to this Agreement); provided, that nothing herein shall prevent any Holder from participating in a Piggyback Underwritten Offering as further described in Section 2.6 below.

2.6 Piggyback Registration Rights.

(a) If the Company at any time proposes to effect an underwritten primary offering for its own benefit or for the benefit of any of its stockholders other than the Holders (in each case, a “Piggyback Underwritten Offering”) and the form of registration statement to be used permits the registration of Registrable Securities, the Company shall give prompt written notice to each Holder of Registrable Securities (which notice shall be given not less than (i) five Business Days prior to the launch of such Piggyback Underwritten Offering or (ii) two Business Days in the case of an Overnight Underwritten Offering, Same-Day Offering or similar “bought deal”), which notice shall offer each such Holder the opportunity to include any or all of its Registrable Securities in such registration statement, subject to the limitations contained in Section 2.6(b) hereof. Each Holder who desires to have its or his Registrable Securities included in such registration statement shall so advise the Company in writing (stating the number of shares desired to be registered) within three Business Days of the launch of such Piggyback Underwritten Offering (or one Business Day in the case of an Overnight Underwritten Offering, Same-Day Offering or similar “bought deal”) after the date of such notice from the Company. Any Holder shall have the right to withdraw such Holder’s request for inclusion of such Holder’s Registrable Securities in any registration statement pursuant to this Section 2.6(a) by giving written notice to the Company of such withdrawal at any time prior to the execution of an underwriting agreement with respect of such Piggyback Underwritten Offering. Subject to Section 2.6(b) below, the Company shall include in such registration statement all such Registrable Securities so requested to be included therein; provided, however, that the Company may at any time withdraw or cease proceeding with any such registration if it shall at the same time withdraw or cease proceeding with the registration of all other equity securities originally proposed to be registered. For the avoidance of doubt, any registration or offering pursuant to this Section 2.6 shall not be considered an Underwritten Shelf Takedown for purposes of Section 2.1 of this Agreement.

(b) With respect to any registration pursuant to Section 2.6(a), if the managing underwriter(s) advise the Company that the inclusion of Registrable Securities requested to be included in the Registration Statement will materially and adversely affect the marketability of the offering (a “Material Adverse Effect”), the Company will be obligated to include in the Registration Statement (after all such shares for its own account), as to each requesting Holder, only a

10

portion of the shares such Holder has requested be registered equal to the product of: (i) the ratio which such Holder’s requested shares bears to the total number of shares requested to be included in such Registration Statement by all Persons (including Holders) who have requested (pursuant to this Agreement or other contractual registration rights) that their shares be included in such Registration Statement; and (ii) the maximum number of Registrable Securities that the managing underwriter advises may be sold in an offering covered by the Registration Statement without a Material Adverse Effect. If, as a result of the provisions of this Section 2.6(b), any Holder shall not be entitled to include all Registrable Securities in a registration that such Holder has requested to be so included, such Holder may withdraw such Holder’s request to include Registrable Securities in such Registration Statement. No Person may participate in any Registration Statement pursuant to Section 2.6(a) unless such Person (i) agrees to sell such person’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Company and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents, each in customary form, reasonably required under the terms of such underwriting arrangements; provided, however, that no such Person shall be required to (A) make any representations or warranties in connection with any such registration other than representations and warranties as to (1) such Person owning his, her or its Registrable Securities to be sold or transferred free and clear of all liens, claims and encumbrances, (2) such Person having power and authority to effect such transfer or sale, (3) such transfer or sale by such Person contemplated by such underwriting agreement, and such Person’s entry into such underwriting agreement, not constituting a breach of any agreements to which such Person is a party or by which such Person is bound, (4) such transfer or sale contemplated by such underwriting agreement, and such Person’s entry into such underwriting agreement, not constituting a breach or violation of such Person’s organizational documents, if the Person is an entity, or any law applicable to such Person and (5) such matters pertaining to compliance with securities laws as may be reasonably requested, or (B) undertake any indemnification obligations to the Company or the underwriters with respect thereto except as otherwise provided in Section 2.7.

2.7 Indemnification.

(a) The Company agrees to indemnify and reimburse, to the fullest extent permitted by law, each Holder that is a seller of Registrable Securities, and each of its employees, advisors, agents, representatives, partners, officers, and directors and each Person who controls such Holder (within the meaning of the Securities Act or the Exchange Act) (collectively, the “Seller Affiliates”) (i) against any and all losses, claims, damages, liabilities and expenses, joint or several (including attorneys’ fees and disbursements except as limited by Section 2.7(c)) based upon, arising out of, related to or resulting from any untrue or alleged untrue statement of a material fact (a) contained in any Registration Statement or any amendment thereof or supplement thereto, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or (b) included in any Prospectus or any amendment thereof or supplement thereto, or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, (ii) against any and all losses, liabilities, claims, damages and expenses whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon, arising out of, related to or resulting from any such untrue statement or omission or alleged untrue statement or omission, and (iii) against any and all costs and expenses (including reasonable fees, charges and disbursements of counsel) as may be reasonably incurred in investigating, preparing or defending against any litigation, investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon, arising out of, related to or resulting from any such untrue statement or omission or alleged untrue statement or omission, or such violation of the Securities Act or Exchange Act, to the extent that any such expense or cost is not paid under subparagraph (i) or (ii) above; except insofar as any such statements are made in reliance upon information furnished to the Company in writing by such seller or any Seller Affiliate expressly for use therein. The reimbursements required by this Section 2.7(a) will be made by periodic payments during the course of the investigation or defense, as and when bills are received or expenses incurred.

(b) In connection with any Registration Statement or Prospectus covering the sale of Registrable Securities in which a Holder that is a seller of Registrable Securities is participating, each such Holder will (i) cooperate with and furnish to the Company such information as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus or any filings with any state securities commissions, (ii) to the extent required by the Securities Act, deliver or cause delivery of the Prospectus to any purchaser of the Registrable Securities covered by such Prospectus from such Holder and (iii) if requested by the Company, notify the Company of any sale of Registrable Securities by such Holder, and to the fullest extent permitted by law, each such seller will indemnify

11

the Company and its directors and officers and each Person who controls the Company (within the meaning of the Securities Act or the Exchange Act) against any and all losses, claims, damages, liabilities and expenses (including reasonable attorneys’ fees and disbursements except as limited by Section 2.7(c)) resulting from any untrue statement or alleged untrue statement of a material fact contained in the (a) Registration Statement or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or (b) Prospectus or any amendment thereof or supplement thereto, or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, but only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission is contained in any information so furnished by such Holder or any of its Seller Affiliates in writing expressly for inclusion in the Registration Statement or Prospectus; provided that the obligation to indemnify will be several, not joint and several, among such sellers of Registrable Securities, and the liability of each such seller of Registrable Securities will be in proportion to the amount of Registrable Securities registered by them, and, provided, further, that such liability will be limited to the net amount received by such seller from the sale of Registrable Securities pursuant to such Registration Statement or Prospectus.

(c) Any Person entitled to indemnification hereunder will (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give such notice shall not limit the rights of such Person) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided, however, that any Person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Person unless (A) the indemnifying party has agreed to pay such fees or expenses or (B) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such Person. If such defense is not assumed by the indemnifying party as permitted hereunder, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld, conditioned or delayed). If such defense is assumed by the indemnifying party pursuant to the provisions hereof, such indemnifying party shall not settle or otherwise compromise the applicable claim unless (i) such settlement or compromise contains a full and unconditional release of the indemnified party or (ii) the indemnified party otherwise consents in writing (which consent will not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified (which shall

be chosen by the Holders of a majority of Registrable Securities so indemnified) by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party, a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the reasonable fees and disbursements of such additional counsel or counsels.

(d) Each party hereto agrees that, if for any reason the indemnification provisions contemplated by Section 2.7(a) or Section 2.7(b) are unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, liabilities or expenses (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the actions which resulted in the losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 2.7(d) were determined by pro rata allocation (even if the Holders or any underwriters or all of them were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 2.7(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses (or actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or, except as provided in Section 2.7(c), defending any such action or claim. Notwithstanding the provisions of this Section 2.7(d), no Holder shall be required to contribute an amount greater than the dollar amount by which the net proceeds received by such

12

Holder with respect to the sale of any Registrable Securities exceeds the amount of damages which such Holder has otherwise been required to pay by reason of any and all untrue or alleged untrue statements of material fact or omissions or alleged omissions of material fact made in any Registration Statement or Prospectus or any amendment thereof or supplement thereto related to such sale of Registrable Securities. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations in this Section 2.7(d) to contribute shall be several in proportion to the amount of Registrable Securities registered by them and not joint.

If indemnification is available under this Section 2.7, the indemnifying parties shall indemnify each indemnified party to the full extent provided in Section 2.7(a) and Section 2.7(b) without regard to the relative fault of said indemnifying party or indemnified party or any other equitable consideration provided for in this Section 2.7(d) subject, in the case of the Holders, to the limited dollar amounts set forth in Section 2.7(b).

(e) No indemnifying party shall be liable for any settlement effected without its written consent. Each indemnifying party agrees that it will not, without the indemnified party’s prior written consent (which consent may not be unreasonably delayed or withheld), consent to entry of any judgment or settle or compromise any pending or threatened claim, action or proceeding in respect to which indemnification or contribution may be sought hereunder unless the foregoing contains an unconditional release, in form and substance reasonably satisfactory to the indemnified parties, of the indemnified parties from all liability and obligation arising therefrom.

(f) The indemnification and contribution provided for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and will survive the transfer of securities.

2.8 Transfer of Registration Rights. The registration rights of a Holder under this Agreement with respect to any Registrable Securities may be transferred or assigned to EnCap Investments, L.P. or its Permitted Transferees; provided, however, that, without the written consent of the Company, no such transfer or assignment may be made unless (i) such Holder shall give the Company written notice prior to the time of such transfer stating the name and address of the transferee and identifying the securities with respect to which the rights under this Agreement are being transferred; (ii) such transferee shall agree in writing, in form and substance reasonably satisfactory to the Company, to be bound as a Holder by the provisions of this Agreement; and (iii) immediately following such transfer the further disposition of such securities by such transferee shall be restricted to the extent set forth under applicable law.

2.9 Free Writing Prospectuses. The Company shall not permit any officer, director, underwriter, broker or any other person acting on behalf of the Company to use any free writing prospectus (as defined in Rule 405 under the Securities Act) in connection with any registration statement covering Registrable Securities, without the prior written consent of each participating Holder and any underwriter. No Holder shall, or permit any officer, manager, underwriter, broker or any other person acting on behalf of such Holder to, use any free-writing prospectus in connection with any registration statement covering Registrable Securities, without the prior written consent of the Company.

2.10 Current Public Information. With a view to making available to the Holders of Registrable Securities the benefits of Rule 144 and Rule 144A promulgated under the Securities Act and other rules and regulations of the SEC that may at any time permit a Holder of Registrable Securities to sell securities of the Company to the public without registration, the Company covenants that it will (i) for as long as the Common Stock is registered pursuant to Section 12(b), Section 12(g) or Section 15(d) of the Exchange Act, use its reasonable best efforts to file in a timely manner all reports and other documents required, if any, to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted thereunder and (ii) if it is not required to file such reports, make available information necessary to comply with Rule 144 and Rule 144A, if available with respect to resales of the Registrable Securities under the Securities Act, at all times, all to the extent required from time to time to enable such Holder to sell Registrable Securities to the public without registration under the Securities Act within the limitation of the exemptions provided by (x) Rule 144 and Rule 144A promulgated under the Securities Act (if available with respect to resales of the Registrable Securities), as such rules may be amended from time to time or (y) any other rules or regulations now existing or hereafter adopted by the SEC.

13

2.11 Company Obligations Regarding Transfers. The Company shall instruct the transfer agent to remove (and shall cooperate with the transfer agent with respect to the removal of) any legend, notation or similar designation restricting transferability of the Registrable Securities from the certificates or book-entries evidencing Registrable Securities if such Common Stock (i) is sold pursuant to an effective registration statement under the Securities Act, (ii) a registration statement covering the resale of the Registrable Securities is effective under the Securities Act and the applicable holder of such Registrable Securities delivers to the Company a representation letter agreeing that such Registrable Securities will be sold under such effective registration statement, (iii) is sold or transferred pursuant to Rule 144 (if the transferor is not an Affiliate of the Company) or (iv) is eligible for sale under Rule 144 without the requirement that the Company has complied with the public reporting requirements of the Exchange Act. Each Holder agrees to provide the Company, its counsel and/or the transfer agent with evidence reasonably requested by it in order to cause the removal of such legend, including, as may be appropriate, any information the Company reasonably deems necessary to determine that the legend, notation or similar designation is no longer required under the Securities Act or applicable state laws, including a certification that the holder is not an Affiliate of the Company (and a covenant to inform the Company if it should thereafter become an Affiliate and to consent to exchange any certificates or instruments representing the Common Stock for ones bearing an appropriate restrictive legend) and regarding the length of time the Common Stock has been held. Any fees of the Company, the transfer agent and Company counsel associated with the issuance of any legal opinion required by the Company’s transfer agent or the removal of such legend shall be borne by the Company.

2.12 Opt-Out Notices. Any Holder may deliver written notice (an “Opt-Out Notice”) to the Company requesting that such Holder not receive notice from the Company of the proposed filing of any Underwritten Shelf Takedown, Piggyback Underwritten Offering, the withdrawal of any Underwritten Shelf Takedown or Piggyback Underwritten Offering or any event that would lead to a Suspension Period, Blackout Period or Suspension Notice as contemplated by Section 2.3; provided, however, that such Holder may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from a Holder (unless subsequently revoked), the Company shall not deliver any such notice to such Holder pursuant to this Agreement and such Holder shall no longer be entitled to the rights associated with any such notice and each time prior to a Holder’s intended use of an effective Registration Statement, such Holder will notify the Company in writing at least two Business Days in advance of such intended use, and if a Suspension Notice was previously delivered (or would have been delivered but for the provisions of this Section 2.12) and the suspension period remains in effect, the Company will so notify such Holder, within one Business Day of such Holder’s notification to the Company, by delivering to such Holder a copy of such previous notice of such Suspension Period, and thereafter will provide such Holder with the related notice of the conclusion of such suspension period immediately upon its availability.

2.13 No Conflict of Rights. The Company represents and warrants that it is not subject to any registration rights that are superior to, inconsistent with or that in any way violate or subordinate the rights granted to the Holders hereby. The Company shall not, prior to the termination of this Agreement, grant any registration rights that conflict with, would prevent the Company from performing, or are superior to or inconsistent with, the rights granted to the Holders hereby.

2.14 Holder Lock-Up Period. In connection with any Underwritten Offering, all participating Holders shall agree to such “lock-up” arrangements with the underwriters thereof, to the extent reasonably requested by the managing underwriter(s) and subject to customary exceptions, equal to the shorter of (A) the shortest number of days that any Holder, any other stockholder of the Company participating in such Underwritten Offering, the Company or any director or executive officer of the Company contractually agrees to with such managing underwriter(s) of such Underwritten Offering not to sell any securities of the Company following such Underwritten Offering and (B) 60 days from the date of the execution of the underwriting agreement with respect to such Underwritten Offering (each such period, a “Holder Lock-Up Period”).

ARTICLE III—TERMINATION

3.1 Termination. The provisions of this Agreement shall terminate and be of no further force and effect upon the first date on which the Holders hold in the aggregate Registrable Securities consisting of less than 1.0% of the issued and outstanding shares of Common Stock and all of such Registrable Securities may be sold freely without restriction and without regard to the current public information or other requirements of Rule 144.

14

(a) This Agreement shall be constructed, interpreted and enforced in accordance with, and the respective rights and obligations of the parties shall be governed by, the laws of the State of Delaware without regard to principles of conflicts of law.

(b) All actions and proceedings for the enforcement of or based on, arising out of or relating to this Agreement shall be heard and determined exclusively in the Delaware Court of Chancery (or, only if the Delaware Court of Chancery declines to accept jurisdiction over the particular matter, any other court of the State of Delaware, or any federal court sitting in the State of Delaware), and each of the parties hereto hereby (i) irrevocably submits to the exclusive jurisdiction of such courts (and, in the case of appeals, appropriate appellate courts therefrom) in any such action or proceeding, (ii) irrevocably waives the defense of an inconvenient forum to the maintenance of any such action or proceeding, (iii) agrees that it shall not bring any such action in any court other than the Court of Chancery of the State of Delaware (or, only if the Delaware Court of Chancery declines to accept jurisdiction over the particular matter, any other court of the State of Delaware, or any federal court sitting in the State of Delaware), and (iv) irrevocably consents to service of process by first class certified mail, return receipt requested, postage prepaid, to the address at which the Company or Holder, as the case may be, is to receive notice in accordance with Section 4.1. The parties hereto agree that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable law.

(c) Each of the parties hereto hereby irrevocably waives any and all rights to trial by jury in any legal proceeding arising out of or related to this Agreement.

4.3 No Third-Party Beneficiaries. This Agreement is for the sole benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever, under or by reason of this Agreement; provided, however, the parties hereto hereby acknowledge that the Persons set forth in Section 2.7 are express third-party beneficiaries of the obligations of the parties hereto set forth in Section 2.7.

15

4.4 Successors and Assigns. Except as otherwise expressly provided herein, this Agreement shall be binding upon and benefit the Company, each Holder and their respective successors and assigns. The Company shall not, directly or indirectly, enter into any merger, consolidation or reorganization in which the Company shall not be the surviving entity unless the surviving entity shall, prior to such merger, consolidation or reorganization, agree to assume the obligations of the Company under this Agreement, and for that purpose references hereunder to “Registrable Securities” shall be deemed to include the common equity interests or other securities, if any, which the Holders would be entitled to receive in exchange for Registrable Securities under any such merger, consolidation or reorganization, provided that, to the extent the Holders receive securities that are by their terms convertible into common equity interests of the issuer thereof, then any such common equity interests as are issued or issuable upon conversion of said convertible securities shall be included within the definition of “Registrable Securities.”

4.5 Counterparts. This Agreement may be executed by the parties in separate counterparts (including by means of executed counterparts delivered via electronic means), each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

4.6 Severability. In case any provision in this Agreement shall be held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and the remaining provisions shall not in any way be affected or impaired thereby.

4.7 No Waivers; Amendments.

(a) No failure or delay on the part of the Company or any Holder in exercising any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies provided for herein are cumulative and are not exclusive of any remedies that may be available to the Company or any Holder at law or in equity or otherwise.

(b) Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Company and Holders who then own beneficially more than 50% of the Registrable Securities.

4.8 Entire Agreement. This Agreement contains the entire agreement between the Holders and the Company with respect to the subject matter hereof and supersede all prior and contemporaneous arrangements or understandings with respect thereto.

4.9 Remedies; Specific Performance.

(a) Each Holder shall have all rights and remedies reserved for such Holder pursuant to this Agreement and all rights and remedies which such Holder has been granted at any time under any other agreement or contract and all of the rights which such Holder has under any law or equity. Any Person having any rights under any provision of this Agreement will be entitled to enforce such rights specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law or equity.

(b) The parties hereto recognize and agree that money damages may be insufficient to compensate the Holders of any Registrable Securities for breaches by the Company of the terms hereof and, consequently, that the equitable remedies of injunctive relief and of specific performance of the terms hereof will be available in the event of any such breach. If any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law.

4.10 Negotiated Agreement. This Agreement was negotiated by the parties with the benefit of legal representation, and any rule of construction or interpretation otherwise requiring this Agreement to be construed or interpreted against any party shall not apply to the construction or interpretation hereof.
