(c) Notwithstanding anything to the contrary contained herein, if, at any time on or after the Execution Date and prior to the Closing, (i) Parent makes (A) any Parent Common Equity dividend or distribution (in each case, that is declared by Parent following the Execution Date), (B) subdivision or split of any Parent Common Equity, (C) combination or reclassification of Parent Common Equity into a smaller number of shares of Parent Common Equity or (D) issuance of any Securities by reclassification of Parent Common Equity (including any reclassification in connection with a merger, consolidation or business combination in which Parent or any acquiror, as applicable, is the surviving Person) or (ii) any merger, consolidation, combination, or other transaction is consummated pursuant to which Parent Common Equity is converted to cash or other Securities, then the Share Price and the number of shares of Parent Common Equity to be issued to Sellers pursuant to this Agreement shall be equitably and proportionately adjusted to reflect such change to provide the same economic effect as contemplated by this Agreement prior to such action, including, for the avoidance of doubt, in the cases of clauses (i)(C) and (ii) to provide for the receipt by Sellers, in lieu of any Parent Common Equity, the same number Securities and/or the amount of cash received in exchange for each share of Parent Common Equity in connection with any such transaction described in clauses (i)(C) and (ii) hereof; provided, however, that in the event of any Parent Common Equity dividend or distribution pursuant to subclause (i)(A), such amounts in respect of such dividend or distribution shall be treated as an upward adjustment to the Cash Purchase Price pursuant to this Agreement. An adjustment made pursuant to the foregoing shall become effective immediately after the record date in the case of a dividend and shall become effective immediately after the effective date in the case of a subdivision, split, combination or reclassification. Notwithstanding anything to the contrary contained herein, no certificates or scrip representing fractional shares of Parent Common Equity shall be issued as part of the Equity Purchase Price, no dividend or distribution with respect to the Parent Common Equity shall be payable on or with respect to any fractional share and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of Parent. In lieu of the issuance of any such fractional share, at Closing, Purchaser shall pay to such Seller an amount in cash determined by multiplying (x) the Share Price by (y) the fraction of a share (rounded to the nearest hundredth when expressed in decimal form) of Parent Common Equity to which such Seller or such Seller’s designees would otherwise be entitled to receive pursuant hereto.

(i) at Closing, all adjustments to the Unadjusted Purchase Price (whether positive or negative) shall be made (x) sixty-five percent (65%) in cash (increasing or decreasing the Cash Purchase Price), and (y) thirty-five percent (35%) in Parent Common Equity (on the basis that each share of Parent Common Equity shall be valued at the Share Price) (increasing or decreasing the number of shares of Parent Common Equity to be issued to the Sellers as part of the Equity Purchase Price): provided, however:

(A) that any upward adjustments under Section 2.4(k) shall be made only in cash (and not in shares of Parent Common Equity), with the remaining adjustment to the Unadjusted Purchase Price settled on the sixty-five percent (65%) / thirty-five percent (35%) pro rata basis set forth in clause (i) above;

(B) the number of shares of Parent Common Equity comprising the Equity Purchase Price at Closing shall not exceed nineteen and ninety-nine hundredths percent (19.99%) of all issued and outstanding shares of Parent Common Equity as of immediately prior to Closing, and with respect to all net upward adjustments made in shares of Parent Common Equity based on the Share Price, such aggregate adjustments as to the Sellers shall be made until such maximum percentage is reached, after which point any additional upward adjustment to the Unadjusted Purchase Price made at Closing shall be made in cash to the Cash Purchase Price only; and

(ii) after Closing, all adjustments to the Unadjusted Purchase Price shall be made in cash.

49

(c) Notwithstanding anything to the contrary in this Agreement, in determining the adjustments contemplated under Section 2.4(a), the following shall be taken into account to the extent not in express conflict with the definitions of Effective Time Working Capital, Working Capital Assets and Working Capital Liabilities; provided, the following shall in no way be construed as a limitation to the definition of any of Effective Time Working Capital, Working Capital Assets and Working Capital Liabilities:

(C) all unpaid proceeds, receivables and amounts earned as of the Effective Time from the sale of Hydrocarbons produced from or attributable to the Oil and Gas Properties, in each case, net of any applicable Customary Hydrocarbon Deductions, together with any other unpaid amounts receivables earned by or owed to such Subject Company Group, in each case during any period before the Effective Time to the extent reasonably likely to be received by the Subject Company Group within the one hundred twenty (120) day period after the Closing Date;

(D) if any member of such Subject Company Group is the operator under an operating agreement covering any of the Assets or assets then owned by such Subject Company Group, an amount equal to the Property Costs and other costs and expenses paid before the Effective Time by such Subject Company Group, such Seller or any of its or their Affiliates on behalf of the other joint

50

interest owners without reimbursement prior to the Effective Time (including through netting of revenues paid to such joint interest owners) that are attributable to periods after the Effective Time, in each case, only to the extent that such costs and expenses are (1) permitted to be charged to such joint interest owners under the applicable joint operating agreement, unit operating agreement, pooling agreement, pooling order or production sharing agreement or similar Contract and (2) reasonably likely to be received by the Subject Company Group (x) within the one hundred twenty (120) day period after the Closing Date or (y) recovered from such Third Party via netting of offsets under applicable Contracts); and

(E) with respect to any Imbalances where such Subject Company Group is underproduced as to Hydrocarbons or has overdelivered Hydrocarbons, an amount equal to the aggregate amount owed by Third Parties to such Subject Company Group for such Imbalances as of the Effective Time if the applicable Contract governing such Imbalance requires monthly cash balancing, or, if monthly cash balancing is not required under such applicable Contract, on the basis of the applicable Settlement Price; and

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

(e) For purposes of allocating Hydrocarbon production (and accounts receivable with respect thereto), (i) liquid Hydrocarbons shall be deemed to be “from or attributable to” the Oil and Gas Properties when they are produced into the tank batteries related to each Well and (ii) gaseous Hydrocarbons shall be deemed to be “from or attributable to” the Oil and Gas Properties when they pass through the delivery point sales meters or similar meters at the point of entry into the pipelines through which they are transported. The Parties shall use reasonable interpolative procedures to arrive at an allocation of Hydrocarbon production when exact meter readings, gauging or strapping data are not available.

51

(f) Surface use or damage fees and other Property Costs that are paid periodically (including deficiency or shortfall payments pertaining to minimum volume commitments or similar requirements that accrue on a periodic basis (e.g., quarterly, semi-annually or annually)) shall be prorated based on the number of days in the applicable period falling on or before, or after, the Effective Time.

(g) “earned” and “incurred,” as used in Section 2.4 and this Section 2.5, shall be interpreted in accordance with accounting recognition guidance under the Accounting Principles.

52

Additional Lease Deposit, each of which shall be exclusively addressed and resolved exclusively under Section 3.2(i)) after giving effect to all adjustments set forth in Section 2.4 and subject to the adjustment procedures specified in Section 2.5, (ii) the Persons, accounts and amounts of disbursements that are required to receive such amounts in accordance with Section 2.6 (including the amounts Sellers designate and nominate to receive the portions of the Closing Payment, Closing Distribution under Section 2.6(a)(iv) and Section 2.6(b) and the Adjusted Equity Purchase Price), and (iii) the wiring instructions for all such payments and disbursements. Each Seller shall supply to Purchaser reasonable documentation in the possession of such Seller and its Subject Company Group to support the items for which adjustments are proposed or made in any such Preliminary Settlement Statement and a brief explanation of any such adjustments and the reasons therefor. Within three (3) Business Days after receipt of the draft Preliminary Settlement Statement, Purchaser may deliver to Sellers a written report containing all changes that Purchaser proposes to be made to the Preliminary Settlement Statement, if any, together with a brief explanation of any such changes, and Sellers shall consider such proposed changes in good faith. Sellers’ and Purchaser shall in good faith attempt to agree on the Preliminary Settlement Statement as soon as possible after Sellers’ receipt of Purchaser’s written report. The Preliminary Settlement Statement, as agreed upon by the Parties, will be used to adjust the Unadjusted Purchase Price at Closing (such estimated Adjusted Purchase Price, the “Closing Adjusted Purchase Price”); provided that if the Parties cannot agree on all adjustments set forth in the Preliminary Settlement Statement prior to the Closing, then any such unagreed adjustments as set forth in the Preliminary Settlement Statement as presented by the Sellers will be used to adjust the Unadjusted Purchase Price at Closing.

(b) As soon as reasonably practicable after the Closing, but not later than one hundred twenty (120) days following the Closing Date, Purchaser shall prepare and deliver to Sellers a draft final settlement statement setting forth the final calculation of the Adjusted Purchase Price allocated and attributable to each Seller (but excluding any adjustments with respect to disputed alleged Defects or Title Defects that Sellers have elected to cure post-Closing for which amounts are included in the Defect Deposit 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)) and showing the calculation of each adjustment under Section 2.4 as to each Seller and Subject Company Group with respect thereto, based on the most recent actual figures for each adjustment. Purchaser shall make reasonable documentation that is in the possession of Purchaser, or its Affiliates or Purchaser’s Representatives, available to support the final figures. As soon as reasonably practicable, but not later than the thirtieth (30th) day following receipt of Purchaser’s statement hereunder, Sellers may deliver to Purchaser a written report containing any changes that Sellers propose be made in such statement, if any, together with a brief explanation of such changes. Any changes not so specified in such written report shall be deemed waived and Purchaser’s determinations with respect to all such elements of a final settlement statement that are not addressed specifically in such report shall prevail (but excluding any adjustments with respect to disputed alleged Defects or Title Defects that Sellers have elected to cure post-Closing for which amounts are included in the Defect Deposit, and any adjustments with respect to disputed alleged Title Benefits and Accepted 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)). If Sellers’ fails to timely deliver a written report to Purchaser containing changes Sellers propose to be made to a final settlement statement, such final settlement statement as delivered by Purchaser

53

will be deemed to be correct and mutually agreed upon by the Parties and will be final and binding on the Parties (and excluding any adjustments with respect to disputed alleged Defects or Title Defects that Sellers have elected to cure post-Closing for which amounts are included in the Defect Deposit, and any adjustments with respect to disputed alleged Title Benefits and Accepted 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 forty-five (45) days following Sellers’ receipt of Purchaser’s statement 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 or Title Defects that Sellers have elected to cure post-Closing for which amounts are included in the Defect Deposit, and any adjustments with respect to disputed alleged Title Benefits and Accepted 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, either Sellers or Purchaser may 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 and Purchaser (the “Accounting Referee”) for review and final determination by arbitration. The Accounting Referee shall conduct the arbitration proceedings in Houston, Texas in accordance with the Commercial Arbitration Rules of the AAA, to the extent such rules do not conflict with the terms of this Section 2.7(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 or Title Defects that Sellers have elected to cure post-Closing for which amounts are included in the Defect Deposit, and any adjustments with respect to disputed alleged Title Benefits and Accepted 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 Section 2.4 and may not increase the Adjusted Purchase Price more than the increase proposed by Sellers 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.

54

(c) Each Seller shall promptly assist (and will cause its Affiliates to 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 each Seller all 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 each Seller to review, audit, dispute and provide comments to the proposed final settlement statement(s) proposed by Purchaser and conduct, respond and prepare and present materials in connection with the Accounting Referee arbitration contemplated hereunder.

(d) Within five (5) Business Days after the earlier of (A) the expiration of Sellers’ thirty (30) day review period without delivery of any written report or objections by Sellers or (B) if Sellers deliver 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 or Title Defects that Sellers have elected to cure post-Closing for which amounts are included in the Defect Deposit, and any adjustments with respect to disputed alleged Title Benefits and Accepted 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)):

(i) if the Adjusted Purchase Price, as finally determined, exceeds the Closing Adjusted Purchase Price (but excluding any adjustments with respect to disputed alleged Defects or Title Defects that Sellers have elected to cure post-Closing, for which amounts are included in the Defect Deposit, and with respect to disputed Accepted 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)) then promptly (and in any event within three (3) Business Days following the final determination of the Adjusted Purchase Price), Purchaser shall pay to the Persons as directed by Sellers by wire transfer of immediately available funds to an account(s) designated by Sellers in writing an amount in cash equal to such excess; or

(ii) if the Closing Adjusted Purchase Price equals or exceeds the Adjusted Purchase Price, as finally determined (but excluding any adjustments with respect to disputed alleged Defects or Title Defects that Sellers have elected to cure post-Closing, for which amounts are included in the Defect Deposit, and with respect to disputed Accepted 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)), then promptly (and in any event within three (3) Business Days following the final determination of the Adjusted Purchase Price), Sellers shall deliver to Purchaser an amount in cash equal to the amount of such excess.

55

(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 in writing.

(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 to Purchaser of all of the assets of the GM II Subject Company by GM II Seller and all of the assets of the GM III Subject Company by GM III Seller, in each case, which assets shall include partnership interests in the NOG Tax Partnership and the Flow-Through Subsidiaries, as applicable. 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 the meaning of Section 1313(a) of the Code or corresponding provision of applicable U.S. state or local Law. Each of Sellers 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 (i) first, among the Flow-Through Subsidiaries and the NOG Tax Partnership (and among the assets of each Flow-Through Subsidiary and the NOG Tax Partnership, as applicable), (ii) second, among the six categories of assets specified in Part II of IRS Form 8594 (Asset Acquisition Statement under Section 1060) with respect to the remainder of the assets of each member of such Subject Company Group (other than the Flow-Through Subsidiaries), in each case, in accordance with Sections 751, 755 and 1060 of the Code and the Treasury Regulations promulgated thereunder (as applicable and in a manner consistent with the applicable Seller’s respective percentage of the Adjusted Purchase Price) within thirty (30) days after the Cut-Off Date (or such other date that is mutually agreed to by the Sellers and the Purchaser) (collectively, the “Allocation”). If the Parties are not able to agree on the portion of the Adjusted Purchase Price and any other items properly treated as consideration for U.S. federal income tax purposes to be allocated to the NOG Tax Partnership and the Flow-Through Subsidiaries (and among the assets of the NOG Tax Partnership and each Flow-Through Subsidiary, as applicable) (the “Partnership Allocations”) within thirty (30) days of the Cut-Off Date (or such other agreed date), the Parties shall submit any items that remain in dispute to the Accounting Referee in accordance with the procedures set forth in Section 2.7(b). The Parties shall request that the Accounting Referee make a decision with respect to all such items within forty-five (45) days after the submission of such items to the Accounting Referee, and in any event as promptly as practicable. The Accounting Referee’s final determination with respect to such matters shall be set forth in a written statement by the Accounting Referee delivered simultaneously to the applicable Seller and Purchaser and shall, absent manifest error, be final, conclusive and binding on the Parties. With respect to the Partnership Allocations, and with respect to the remainder of the Allocation to the extent the Sellers and Purchaser reach an agreement with respect to the Allocation, (a) Sellers and Purchaser shall use commercially reasonable efforts to update the Allocation in a manner consistent with Sections 751, 755 and Section 1060 of the Code following any adjustment to the purchase consideration for Tax purposes pursuant to this Agreement, and Sellers and Purchaser 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 shall timely file with the IRS, and neither Sellers

56

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 and Purchaser cannot mutually agree on the Allocation, each Party shall be entitled to determine its own allocation and file its IRS Form 8594 consistent therewith (other than with respect to the Partnership Allocations) 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 any Seller such amounts as are required to be withheld therefrom 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 a Seller to deliver the form described in Section 10.2(d), Purchaser will, prior to any deduction or withholding, use commercially reasonable efforts to notify such Seller of any anticipated withholding, and reasonably cooperate with such Seller and its Affiliates to minimize the amount of any applicable withholding to such affected Person. 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 the applicable Seller in respect of which such deduction or withholding was made.

57

commercially reasonable efforts to provide to Sellers updates no later than 5:00 p.m. Central Time every other 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 updates or notices with respect to any Defect shall not in any way prejudice or restrict 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 each alleged Defect, each such Notice shall be in writing and must include, the following:

(i) a description of the alleged Defect;

(ii) a description of the Asset, including the DSU or Well and Subject Formation(s), subject to such alleged Defect;

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

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

(v) 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.

SUBJECT TO, AND WITHOUT LIMITATION OF, SELLERS’ REPRESENTATIONS AND WARRANTIES SET FORTH IN SECTION 4.5, SECTION 5.8, SECTION 5.13, SECTION 5.15(A), SECTION 5.16, SECTION 5.17, SECTION 5.18, SECTION 5.21, SECTION 5.22, SECTION 5.33, SECTION 5.36, SECTION 5.37 AND SECTION 5.38, THE CONDITIONS TO CLOSING SET FORTH IN ARTICLE 9 AND THE RIGHTS AND REMEDIES SET FORTH IN ARTICLE 12 AND ARTICLE 13, ABSENT FRAUD, PURCHASER PARTIES 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 HAVE NOT RECEIVED ON OR BEFORE THE DEFECT DEADLINE A DEFECT NOTICE THAT SATISFIES ALL OF THE CONDITIONS AND REQUIREMENTS SET FORTH IN THIS SECTION 3.2(A) (OR WITH RESPECT TO SECTION 3.2(A)(I), SECTION 3.2(A)(V) AND SECTION 3.2(A)(VI), IN ALL MATERIAL RESPECTS).

58

(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 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 such 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;

(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 consistent with the scope of Reasonable Documentation as is 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 HAVE 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 Defects after Closing, then Sellers shall notify Purchaser of its election prior to or contemporaneously with Sellers’ delivery of the Preliminary Settlement Statement. Alleged Defects shall be deemed to have been cured or removed if Sellers 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 DSU or Wells affected by such alleged Defect are free of such Defect as of the applicable Cure Deadline or (ii) with respect to Environmental Defects, such Environmental Defect has been Remediated as of the applicable Cure Deadline. If any asserted Defect is not cured or removed, or if Sellers and Purchaser cannot agree as to whether such Defect has been cured, Remediated, or removed, and it is determined by the applicable Defect Referee that such Defect is not cured by the applicable 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.

59

(d) Defect Amounts. The diminution of value of the Assets attributable to any valid Defect that burdens an Asset (the “Defect Amount”) shall be determined as follows:

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

(ii) subject to Section 3.2(d)(vii), 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;

(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, over the productive life of such Well or DSU, 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,

60

the values placed upon the Title Defect by Purchaser and Sellers, 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;

(v) if a Defect is an Environmental Defect, the Defect Amount shall be equal to the costs and expenses chargeable to the Subject Company Group’s Working Interest or interest (as of the Closing Date) 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), may be the lowest-cost manner reasonably available if such non-permanent remedies are effective, in compliance with applicable Environmental Laws and the requirements of applicable Governmental Authorities and allow for the continued operation of the relevant Asset(s); 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), and (C) overhead costs of Purchaser or its Affiliates;

(vi) subject to and without limitation of Section 3.2(f), 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 Defects with respect to each 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 personal recourse to any member of the Subject Company Group (so long as such recourse is not limited to the Assets subject to such Lien).

(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

61

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 the 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 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 Sellers, and such other reasonable factors as are necessary to make a proper evaluation and determination of such value.

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

(i) except as otherwise provided in Section 3.2(f)(iii), 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 Defect Threshold (it being agreed that the Individual Defect Threshold represents a threshold and not a deductible);

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

62

(iii) notwithstanding anything herein to the contrary: (A) if a single Title Defect arising from a single fact or circumstance (rather than a single type of Title Defect) affects multiple Wells or DSUs, then the Defect Amounts with respect to such single Title Defect as to all such Wells or DSUs as to all affected Subject Company Groups shall be aggregated for purposes of calculating whether the Defect Amount associated with such Title Defect exceeds the applicable Individual Defect Threshold and (B) if a single Title Defect (rather than a single type of Title Defect) affects more than one Subject Formation within a single Well or DSU, then the Defect Amounts with respect to such single Title Defect as to all affected Subject Formations within such single Well or DSU shall be aggregated for purposes of calculating whether the Defect Amount associated with such Title Defect exceeds the applicable Individual Defect Threshold;

(iv) notwithstanding anything herein to the contrary (and without limitation of Section 8.18 or Section 8.19), with respect to any Defect that is a Title Defect, the applicable Individual Defect Threshold and the Defect Deductible shall not apply to any recourse under this Agreement (including any adjustments to the Unadjusted Purchase Price) with respect to any Special Warranty Defect; and

(v) the Parties agree that for purposes of calculating the Individual Defect Threshold pursuant to this Section 3.2(f), if an Environmental Defect which is solely a regulatory or permitting deficiency and not a physical condition affects multiple 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 each such Environmental Defect that is common across multiple Assets may be aggregated for purposes of meeting the Individual Defect Threshold.

(g) Sole and Exclusive Remedies for Defects. Subject to 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 (and further subject to Purchaser’s right to dispute the validity of such cure or Remediation) on or prior to the applicable Cure Deadline, then:

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

63

(ii) notwithstanding anything herein to the contrary, in lieu of the remedy for Title Defects set forth in Section 3.2(g)(i), Sellers shall have the right, but not the obligation, to elect in writing delivered to Purchaser on or 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 the portion of any other Assets as are necessary (and then only to the extent necessary) for the ownership or operation of such Assets) from the transactions contemplated hereunder if the Defect Amount(s) attributable to such Oil and Gas Property equals or exceeds 90% of the Allocated Value of such Oil and Gas Property and, in such event, (A) the Unadjusted Purchase Price with respect to such 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).

(h) Remedies for Title Benefits. Subject to Purchaser’s right to dispute the existence of a Title Benefit and the Title Benefit Amount asserted with respect thereto and the terms of Section 8.19, the amount of any decrease to the Unadjusted Purchase Price under Section 3.2(g) with respect to a given Subject Company Group shall be offset by the sum of the aggregate Title Benefit Amounts attributable to all such Title Benefits with respect to such Subject Company Group; provided that, for the avoidance of doubt, that a Title Benefit may only offset a Defect, and may not result in any standalone increase to the Unadjusted Purchase Price.

(i) Disputed Defects; Defect Escrow.

(i) Sellers and Purchaser shall use good faith efforts to agree prior to Closing (and if applicable for any Title Defects that Sellers have elected to attempt to cure after Closing, prior to the Cure Deadline) on the interpretation and effect of this Article 3 and the validity and determination of all Title Benefits, Title Benefit Amounts, Defects and Defect Amounts (or the cure or Remediation thereof). If Sellers and Purchaser are unable to agree (A) on the scope, interpretation and effect of this Article 3, the existence, cure or amount of any Title Benefits, Title Benefit Amounts, Defects or Defect Amounts by the Closing Date, or if Sellers have elected to attempt to cure any Title Defects following the Closing Date, or (B) as to any Additional Leases or Additional Lease Purchase Price, then (1) no adjustments shall be made to the Unadjusted Purchase Price at Closing with respect to such disputed Title Benefits, Title Benefit Amounts, Defects, Defect Amounts, Additional Leases or Additional Lease Purchase Price, and (2) with respect to any such (I) disputed Defects or Defect Amounts associated with Title Defects which Sellers have elected to cure following the Closing Date or (II) Additional Leases or Additional Lease Purchase Price, at Closing, Purchaser shall deposit with the Escrow Agent a portion of the Cash Purchase Price equal to the Defect Deposit and/or the Additional Lease Deposit, as applicable, in accordance with Section 10.3(c) and/or Section 10.3(d), which shall be held by the Escrow Agent and released to the appropriate Party as provided in this Section 3.2(i) and the terms of the Escrow Agreement.

64

(ii) If Sellers and Purchaser are unable to agree on the interpretation and effect of this Article 3, the existence, cure, Remediation or amount of (A) (1) any disputed Title Benefits, Title Benefit Amounts, Title Defects, or Defect Amounts associated with Title Defects, or (2) whether any Additional Lease meets the requirements set forth in Section 8.18 or the Additional Lease Purchase Price (each, a “Title Disputed Matter”) by the date one hundred thirty (130) 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 date that is thirty (30) days after 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 one hundred thirty (130) days after the Closing Date, each of Sellers and Purchaser 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 where the applicable Asset is located as selected by mutual agreement of Purchaser and Sellers, 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 date thirty (30) days after 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 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”). If the Defect Referee is not agreed upon during the ten (10) Business Day period described above, then the deadline for either Party to submit its written proposal with respect to the applicable Disputed Defect Matters shall be tolled until ten (10) Business Days after the applicable Defect Referee is appointed. 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. 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 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 8.18, 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

65

or Defect Amount, neither Purchaser nor Sellers may submit any evidence, records, materials, or information that was not included either in a valid Defect Notice delivered to Sellers 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.

(iv) In no event shall the Defect Referee’s determination of (A) any Defect Amount with respect to any Defect be any lower than the amount asserted by Sellers for such Defect or any greater than the amount asserted by Purchaser for such Defect or (B) any Title Benefit Amount with respect to any Title Benefit be any lower than the amount asserted by Purchaser for such Title Benefit or any greater than the amount asserted by Sellers for such Title Benefit. 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 properly submitted by any Party to such Defect Referee and may not award any damages, interest or penalties to any Party with respect to any matter. The costs and expenses of the Defect Referee shall be borne by Sellers, on the one hand, and 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 aggregate amount actually contested by such Party. Promptly, and in any event within three (3) Business Days following the final determination by the applicable Defect Referee as to any Disputed Defect Matter, or within three (3) Business Days following the Cure Deadline (to the extent that Sellers and Purchaser have agreed that Sellers have cured a Title Defect after Closing and on or before the Cure Deadline), Purchaser and Sellers 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.

Such access shall be granted to Purchaser (x) with respect to the Records stored in electronic form, in the VDR, (y) with respect to the Records not stored in electronic format, in the offices of Sellers or its Affiliates and (z) otherwise, on the premises of the applicable Assets; provided, however, in no event shall any Seller or any Subject Company be obligated to provide, and Purchaser and Purchaser’s Representatives shall have no right to receive or review (A) any personnel records of, or relating to, any individual that is employed by any Subject Company (other than information required to be disclosed pursuant to Section 8.8), (B) prior to Closing, any Excluded Records or (C) prior to Closing, any email correspondence of any Subject Company, except to the extent constituting Records.

98

(d) In furtherance and not in limitation of the foregoing, Seller and each Purchaser Party shall (i) each furnish to the other Party as promptly as reasonably practicable all information required for any application or other filing to be made by the other Party pursuant to any applicable Law in connection with the transactions contemplated hereby, (ii) make an appropriate response as promptly as reasonably practicable to any request for additional information or documentation, by the Antitrust Division of the U.S. Department of Justice (the “DOJ”), the Federal Trade Commission (the “FTC”) or by any other Governmental Authority in respect of such registrations, declarations and filings or such transactions, (iii) promptly notify the other Party of any material communication between that Party and the FTC, the DOJ or any other Governmental Authority, (iv) discuss with and permit the other Party (and its counsel) to review in advance, and consider in good faith the other Party’s reasonable comments in connection with, any proposed filing or communication to the FTC, the DOJ or any other Governmental Authority or, in connection with any Action by a private party to any other Person, relating to any regulatory Law or any investigation or Action pursuant to any regulatory Law in connection with the transactions contemplated hereby, (v) not participate or agree to participate in any meeting, telephone call or discussion with the FTC, the DOJ or any other

(a) At and after Closing, subject to and in compliance with Section 8.25, Sellers may retain, at their sole cost and expense, (i) copies of any and all Records and (ii) originals (whether electronically or in hard copy format) of any and all Excluded Records and any data constituting an Excluded Assets; provided that, to the extent that such information has not been removed or extracted from any networks or servers of the Subject Company Group as of the Closing Date, for a period of up to one hundred twenty (120) days after Closing, Purchaser shall, and shall cause its Affiliates (including the Subject Company Group) to, reasonably cooperate with Sellers (at Sellers’ sole cost, expense and risk), to complete the extraction of any such Excluded Records or data; provided, further that Purchaser may condition its cooperation on the execution and delivery of customary access indemnity and/or confidentiality agreements and compliance by Seller or its representatives with Purchaser or Purchaser Parent’s internal policies and procedures. 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.

(b) Notwithstanding the provisions of Section 8.8(a)(i), 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 with 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.

111

part of such Records as such Seller may select. From and after Closing, Purchaser and each Subject Company shall provide to such Seller, at no out-of-pocket cost or expense to such Seller, reasonable access to such books and records pertaining to the Assets or the Business of the Subject Company Group with respect to periods prior to Closing and remain in any Purchaser Entity’s and/or each Subject Company’s possession or control and reasonable access to the Assets and other properties and employees of any Purchaser Entity and/or any Subject Company in connection with matters relating to the ownership or operations of the Assets, or any claims or disputes (a) relating to this Agreement, (b) amongst any members of the Seller Group or (c) with any Third Parties (for the purpose of examining and copying at Sellers’ sole expense), at reasonable times and upon reasonable advance notice to Purchaser, insofar as and only to the extent such books and records were generated by or on behalf of the Subject Company Group prior to Closing, and then only to the extent that such books and records (i) relate to Seller Taxes, (ii) relate to any Specified Liabilities or other matters, Actions, Damages or claims for which any Seller is required to bear or provide indemnification hereunder or (iii) are reasonably necessary for Seller to defend or prosecute any claim for which Seller owes an obligation of indemnification to Purchaser or its Affiliates under this Agreement; provided Purchaser and Company shall not be obligated to provide such access or any such information to the extent that providing such access or information (A) violates applicable Laws or causes a breach of any Contract existing as of the Closing Date, (B) waives any legal privilege (as reasonably determined by Purchaser’s counsel) of Purchaser, Company or any member of the Purchaser Group, any of their respective Affiliates to the extent such privilege arises after Closing, or (C) violates any confidentiality obligation of Purchaser or any member of Purchaser Group to any Third Party existing prior to the Execution Date.

(c) If requested by Purchaser, Sellers shall, for a period not to exceed three (3) months after Closing, and at no out of pocket expense to Sellers (unless Purchaser has agreed in writing to pay or advance such amounts) use commercially reasonable efforts to assist Purchaser in connection with the transfer or transition of any licenses and/or related data that (i) are included in the Excluded Records or Excluded Assets and (ii) are reasonably necessary to operate the Business in the ordinary course.

Section 8.9 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 “Grayson Mill”, “Grayson Mill Energy”, “GME”, 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. In furtherance thereof, (i) within sixty (60) days after the Closing Date, Purchaser shall 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, Purchaser shall remove, strike over or otherwise obliterate or cease using all Subject Marks from all Assets and materials, including, without limitation, 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 “Grayson Mill”, “Grayson Mill Energy”, “GME”, 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 (B) 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 8.10 Indemnification of Directors and Officers.

(a) For a period of six (6) years from and after the Effective Time, each Subject Company shall indemnify and hold harmless (and advance funds in respect of each), in the same manner (and no broader than) as required by the Governing Documents of the applicable Subject Company Group immediately prior to the Execution Date, each present and former director, manager, officer and employee of each Subject Company (in all of their capacities as such with respect to the Subject Company Groups) (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 Effective Time (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 provide advancement of expenses to the Subject Company Groups Indemnified Parties, in all such cases to the same extent that (and no broader than) 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 (each of which have been made available to the Purchaser).

(b) Purchaser and each Subject Company agree that, until the six (6) year anniversary date of the Closing Date, the Governing Documents of each Subject Company shall contain provisions no less favorable with respect to indemnification of Subject Company Groups Indemnified Parties than are provided in the Governing Documents of the applicable members of the Subject Company Groups Indemnified Parties in existence on the Execution Date, which provisions shall not be amended, repealed or otherwise modified after the Closing in any manner that would adversely affect the rights thereunder of any Subject Company Groups Indemnified Parties with respect to indemnification or advancement of expenses unless such amendment, modification or repeal is required by applicable Law.

(c) At or prior to the Closing, Sellers shall cause the Subject Companies to obtain (and fully prepay, subject to reimbursement by Purchaser at Closing of one hundred percent (100%) of the premium thereof), a “tail” policy from an insurer with substantially the same or better credit rating as the current carrier(s) for the existing D&O Insurance of the Subject Company Groups that provides coverage for acts or omissions occurring prior to the Effective Time covering each such Person covered by the D&O Insurance of the Subject Company Groups as of the Effective Time 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 effect on the Execution Date and with a term of six (6) years from the Effective Time; 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 existing annual premium currently paid by the Subject Company Groups for such coverage; and provided, further, however, that if any annual premium for such insurance coverage exceeds three hundred percent (300%) of such existing annual premium, Purchaser shall obtain as much coverage as reasonably practicable for a cost not exceeding such amount. From and after the 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 each Subject Company.

113

(d) The provisions of this Section 8.10 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. To the extent provided in the Governing Documents of the Subject Company Groups in effect as of the Execution Date, the Subject Companies shall pay all reasonable out-of-pocket expenses, including reasonable attorneys’ fees, that may be incurred by any Subject Company Groups Indemnified Party in enforcing the indemnity obligations provided in this Section 8.10 unless it is ultimately determined pursuant to the Governing Documents of the Subject Company Groups in effect as of the Execution Date that such Subject Company Groups Indemnified Party is not entitled to such indemnity.

(e) For a period of six (6) years after the Closing Date, if any Purchaser Entity 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 the successors and assigns of such Person assume the indemnification obligations set forth in this Section 8.10.

Section 8.11 Employee Matters.

(a) No later than five (5) days after the HSR Clearance Date, Sellers shall provide Purchaser with a list of (i) the Business Employees, as of, which such list includes the following for each Business Employee: (A) name or employee identification number, (B) job title; (C) date of hire; (D) primary work location; (E) base annual salary or hourly wage rate, as applicable; (F) exempt or non-exempt classification, (G) active or inactive status, (H) employing entity, (I) visa status (if applicable), (J) accrued but unused paid time off, and (K) current year target incentive compensation, as applicable; and (ii) individuals engaged by a Seller or its Affiliate (whether in their personal capacity or through a limited liability company of which they are the sole member) as independent contractors who provide material services to the Business or Assets, including for each, (1) a description of the Contract applicable to such services, (2) a description of the services provided, and (3) primary work location; provided, however, that such information will be shared in non-anonymized and unredacted form pursuant to the procedure outlined in the Clean Team Agreement between the Parties and under the supervision of the Parties’ antitrust counsel. Such lists shall be updated ten (10) Business Days prior to the Closing.

(b) From the Closing Date until the first (1^st) anniversary thereof (or, if earlier, the date of a Continuing Employee’s termination) (the “Continuation Period”), Purchaser shall provide each Business Employee who is employed by a Subject Company or a Subsidiary as of immediately prior to the Closing Date and who continues employment immediately upon the Closing (collectively, the “Continuing Employees”) with (i) an annual base salary or hourly wage level, as applicable, and target annual cash bonus opportunities at least equal to those provided to each such Continuing Employee immediately prior to the Closing and (ii) employee benefits (excluding defined benefit plans, retiree health or welfare benefit plans, nonqualified deferred compensation plans, and equity and equity-based compensation plans) that are substantially comparable in the aggregate to those provided to similarly situated employees of the Purchaser or its Subsidiaries (subject to the same exclusions).

114

(c) Purchaser agrees that it shall assume (or cause one of its Subsidiaries to assume) the Subject Company Group Severance Plan, and shall fulfill (or cause one of its Subsidiaries to fulfill) all obligations that apply to the Subject Company or its successor or any Subsidiary thereof under the Subject Company Group Severance Plan. For the avoidance of doubt, during the Continuation Period, Purchaser shall not (and, as applicable, shall cause its Subsidiaries not to) terminate or alter or amend the Subject Company Group Severance Plan in any manner not permitted by the terms thereof.

(d) If the Closing Date occurs more than one hundred twenty (120) days after the start of the applicable Subject Company’s (or its Subsidiary’s) fiscal year, Purchaser shall ensure, or shall cause the applicable Subject Company or Subsidiary to ensure, that each Continuing Employee who remains employed with the Subject Company as of such date receives an annual bonus in respect of the fiscal year in which the Closing Date occurs in an amount equal to the Continuing Employee’s target annual bonus; provided, that the Purchaser shall have no obligations under this Section 8.11(d) in respect of bonus amounts exceeding $5,000,000 (in the aggregate for all eligible Continuing Employees).

(e) Purchaser shall use commercially reasonable efforts to (or shall cause its Subsidiaries to use commercially reasonable efforts to), for the plan year in which the Closing occurs: (i) waive all limitations as to pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Continuing Employees and their eligible dependents under any group health plans in which such Continuing Employees and their eligible dependents are eligible to participate after the Closing Date to the extent that such limitations were waived or satisfied under the corresponding Plan that provides group health benefits and (ii) provide each Continuing Employee with credit for any co-insurance and deductibles paid prior to the Closing Date in satisfying any applicable deductible or out-of-pocket requirements under any group health plans in which such Continuing Employee and such Continuing Employee’s eligible dependents are eligible to participate after the Closing Date. For the avoidance of doubt, Purchaser shall (or shall cause its Subsidiaries to) continue to honor any paid time off accrued and unused by a Continuing Employee through the Closing Date. With respect to any Plan maintained by Purchaser or its Subsidiaries in which any Continuing Employee is eligible to participate on or after the Closing Date (including any Plan continued by Purchaser or its Subsidiaries), Purchaser shall provide, or cause the applicable Subject Company or Subsidiary to provide, credit for purposes of determining eligibility to participate, level of paid time off benefits, and vesting for full or partial years of service with Seller or its Affiliates (including the Subject Companies and any predecessor employer) performed at any time prior to the Closing Date; provided that the foregoing shall not apply to the extent that it would result in any duplication of benefits or compensation to any Continuing Employee for the same period of service. Sellers and their respective Affiliates agree that, notwithstanding the terms of any non-competition, non-solicit, non-disclosure, non-interference, or similar restrictive covenant between any 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 Sellers shall not (and shall cause their Affiliates and Subsidiaries not to) seek to enforce the terms of any such RCA following the Closing.

115

(f) The applicable Subject Company shall cause the board of directors (or equivalent governing body) of such Subject Company to adopt, no later than the day prior to the Closing Date, a written consent (the form of which shall have been approved by Purchaser, whose approval shall not be unreasonably withheld) terminating the Grayson Mill Energy, LLC Retirement Plan (the “401(k) Plan”), with such termination to be effective no later than the day immediately prior to the Closing Date. Prior to the Closing Date, the Subject Companies shall notify participants in the 401(k) Plan of the termination of the 401(k) Plan.

(g) Purchaser shall not, and shall cause its Affiliate not to, take any action following the Closing that results in WARN Act liability for Sellers or their Affiliates, subject to the accuracy of the information provided by Sellers as referenced in the last two sentences of this Section 8.11(g). No later than ten (10) days prior to the Closing Date, Sellers will provide Purchaser with a list, by termination date and work location, setting forth each employee or former employee of Seller and its Affiliates who has incurred an “employment loss” (as defined by the WARN Act) at any site of employment where a Business Employee is located in the ninety (90) days prior to the date of such list. Such list will be updated one (1) day prior to the Closing Date to reflect such information in the ninety (90) days prior to Closing.

(h) During the period between the Execution Date and the Closing Date, Sellers shall use commercially reasonable efforts to make the Seller Management Persons and those individual independent contractors who are providing services related to the operation of the Assets and engaged by Seller or its Affiliates (including a member of the Subject Company Group) available to Purchaser or its Affiliates for the purpose of allowing Purchaser and its Affiliates to interview each such Seller Management Person and contractor and determine the nature and extent of each such Person’s continuation with Purchaser or its Affiliates, if any.

(i) The provisions of this Section 8.11 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 or other current or former employee of a member of the Subject Company Group, Sellers or any of their respective Affiliates including any right to employment or continued employment for any specified period, or compensation or benefits of any nature or kind whatsoever under this Agreement), 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 8.11) under or by reason of any provision of this Section 8.11. Nothing in this Section 8.11, express or implied, shall be (i) deemed an establishment, amendment, modification for any purpose, or termination of any Plan or any other employee benefit or compensation plan, program, policy, contract, agreement or arrangement, or (ii) construed to prevent Purchaser or its Affiliates from creating, amending, terminating or modifying to any extent or in any respect any employee benefit or compensation plan, program, policy, contract, agreement or arrangement that Purchaser or its Affiliates may establish or maintain at any time.

116

Section 8.12 Financial Information.

(a) From and after the Execution Date until the date that is six (6) months following the Closing Date (the “Records Period”), each Seller and the Subject Companies agree to use commercially reasonable efforts (i) to make available to Purchaser and its Affiliates and their agents and representatives any and all Records to the extent in the Sellers’ or the Subject Companies’ or their respective Affiliates’ possession or control and to which Sellers’ or the Subject Companies’ and their respective Affiliates’ personnel have reasonable access, in each case as reasonably required by Parent, its Affiliates and their agents and representatives in order to prepare financial statements (including pro forma financial statements that comply with the rules and regulations of the SEC, including the requirements of Regulation S-X) in connection with a Financing or any required filing by the Parent or its Affiliates with the SEC, meeting the requirements of Regulation S-X under the Securities Act (“Purchaser Financial Statements”), and (ii) in connection with filings by Parent with the SEC under securities Laws applicable to Parent, or as otherwise reasonably requested by Purchaser in connection with any registration of securities under the Securities Act or a Financing, to use commercially reasonable efforts to cooperate with Parent in connection with Parent’s preparation of Purchaser 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.

(b) During the Records Period, each Seller and the Subject Companies shall use commercially reasonable efforts to cause their respective accountants, counsel, agents and other Third Parties to cooperate with Parent and their representatives in connection with a Financing or the preparation by Parent of Purchaser Financial Statements that are required to be included in any filing by Parent or its Affiliates with the SEC, provided that Parent shall be solely responsible for any costs or expenses associated therewith. If requested, each of the Sellers and the Subject Companies and their respective Affiliates shall use commercially reasonable efforts to execute and deliver to the external audit firm that audits the Purchaser Financial Statements (the “Audit Firm”) such representation letters, in form and substance customary for representation letters provided to external audit firms by management of the company whose financial statements are the subject of an audit, as may be reasonably requested by the Audit Firm, with respect to a Financing or the Purchaser Financial Statements, including, as requested, representations regarding internal accounting controls and disclosure controls.

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, in each case, to the extent set forth on Schedule 8.13 (collectively, the “Existing Credit Support”) shall be maintained after Closing. At or prior to the Closing, the Purchaser Parties shall post and provide evidence of any and all replacement Credit Support to the extent necessary to obtain the release, return, and replacement of all Existing Credit Support, 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 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 return or reimbursement of the Sellers for any cash deposits constituting Existing Credit Support.

(b) In the event that HSR Clearance has not occurred prior to the Initial Outside Date, from and after the Initial Outside Date and prior to Closing, any Subject Company 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 obligations under the Credit Documents and any and all such Hedges shall constitute “Additional Subject Company Hedges”. Such Additional Subject Company Hedges shall be for the sole benefit, cost and expense of Sellers and will be treated as Subject Company Hedges for all purposes (including the obligations to terminate, liquidate and unwind any such Additional Subject Company Hedges, if remaining at Closing, pursuant to Section 8.14(a)).

Section 8.15 Subject Company Groups Credit Document Matters. Subject in all cases to the covenants and agreements in Section 8.2(b)(xiii), in the event HSR Clearance is not obtained prior to the Initial Outside Date, then from and after the Initial Outside Date until the Closing Date, any Subject Company may enter into amendments, extensions, supplements and/or replacements of any of the Credit Documents and incur such additional Post-Effective Time Credit Document Indebtedness as necessary in order to conduct the Business in the ordinary course, consistent with past practice and the general plan of operations set forth in the Ordinary Course Development Plan; provided that Sellers shall (and shall cause their respective Subject Company Group to) provide prior written notice to Purchaser of any such amendment, extension, supplement or replacement, or incurring any such additional Post-Effective Time Credit Document Indebtedness.

(a) Purchaser acknowledges that one or more Subject Company holds the data and geophysical licenses and permits described on Schedule 8.16 (each a “Seismic License”).

For purposes hereof, the term “Additional Lease” means a Hydrocarbon lease, fee mineral interest, royalty interest, overriding royalty interest, net profits interest and any other similar interest that satisfies all of the following criteria: (a) 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), but excluding any such Hydrocarbon lease acquired pursuant to a term assignment, (b) burdens one or more Subject Formations located within the Acquisition Area, (c) is held by production or has a primary term that does not expire prior to August 1, 2025, (d) entitles the lessee thereunder to a Net Revenue Interest in the applicable Subject Formation(s) for such Additional Lease equal to or greater than the product of (i) seventy-eight percent (78%) multiplied by (ii) the lessee’s Working Interest in such lease as to such Subject Formation(s), (e) does not include a prohibition on pooling and (f) 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 (i) described on any Annex to Exhibit A-1 or any renewals, replacements, or extensions thereof, (ii) any leases that cure any Title Defects, or (iii) any additional interests in the Leases or DSUs acquired by forced pooling or non-consent elections.

Thereafter, Purchaser shall have until the earlier of the date that is one (1) Business 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 (or is deemed to have elected) to acquire, or for the Subject Company to retain, being referred to herein as an “Accepted Additional Lease”); provided that Purchaser agrees that it shall be deemed to have elected to acquire any and all Additional Leases (and such leases shall constitute Accepted Additional Leases) pursuant to this Section 8.18(b) for which the aggregate Additional Lease Purchase Prices for all such Additional Leases do not exceed Thirty Million Dollars $30,000,000.

(c) 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 Adjusted Purchase Price at Closing shall be increased by the Additional Lease Purchase Price attributable to all such Additional Leases. The Sellers and Purchaser shall use good faith efforts to agree on the interpretation and effect of this Section 8.18 and the validity and determination of all Additional Leases and Additional Lease Purchase Prices with respect thereto. If the Sellers and Purchaser are unable to agree on the interpretation and effect of this Section 8.18, whether a Hydrocarbon lease constitutes an Additional Lease, the existence or amount of any 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 8.18 shall be exclusively and finally resolved by the Title Referee in accordance with the terms of Section 3.2(i), mutatis mutandis.

Section 8.19 Permitted Trades.

(a) Subject to the provisions and limitations set forth in this Section 8.19, from and after the Execution Date until the Additional Lease Acquisition Deadline one or more members of a Subject Company Group may enter into certain acreage trade agreements (each, a “Trade Agreement”) with one or more Third Parties (a “Trade Counterparty”), pursuant to which (A) such member(s) of a Subject Company Group would convey and transfer to the relevant Trade Counterparty interests in Oil and Gas Properties that (1) are not operated by any member of a Subject Company Group or (2) are located within lands identified on Schedule 8.19(a) (such Oil and Gas Properties, the “Outgoing Trade Assets”) with respect to the relevant Trade Agreement and (B) in exchange such member(s) of a Subject Company Group would receive from such Trade Counterparty interests in certain oil, gas and/or mineral leases, wells or lands

120

located within the DSUs identified on Exhibit A-3 as operated or prospectively operated by a member of a Subject Company Group (other than those lands identified on Schedule 8.19(a)) of at least equivalent value to the Outgoing Trade Assets (the “Incoming Trade Assets”). Prior to consummating any Trade Agreement, Sellers will notify Purchaser in writing (each, a “Trade Notice”), which shall (i) identify the Outgoing Trade Assets, (ii) identify the Incoming Trade Assets, (iii) describe any Wells producing from the Outgoing Trade Assets or Incoming Trade Assets, and (iv) include such additional information as is reasonably necessary for or requested by Purchaser to confirm the transaction contemplated by the Trade Agreement contemplates an exchange of substantially equivalent value. The applicable members of the Subject Company Group may enter into such Trade Agreement without Purchaser’s consent to the extent the Allocated Values of all Outgoing Trade Assets for such Trade Agreement plus all other permitted Trade Agreements do not exceed Ten Million Dollars ($10,000,000). In the event that the Allocated Values of all Outgoing Trade Assets for all other permitted Trade Agreements equals or exceeds Ten Million Dollars ($10,000,000), then for any subsequent Trade Agreements within ten (10) days of receiving a Trade Notice, Purchaser will notify Sellers whether it consent to the execution and delivery of the Trade Agreements (such consent not to be unreasonably withheld, conditioned or delayed); provided that, Purchaser may reasonably withhold its consent to a Trade Agreement if (A) Purchaser determines in good faith that the Incoming Trade Assets do not have at least the equivalent value to the Outgoing Trade Assets. Failure of Purchaser to affirmatively deny any required consent to a Trade Agreement via written Notice to Sellers under this Section 8.19(a) within such ten (10) day period shall be deemed to constitute a consent by Purchaser to such Trade Agreement. Any Trade Agreement that is permitted under this Section 8.19(a) or is consented to or deemed to be consented to by Purchaser pursuant to this Section 8.19(a) is referred to as a “Permitted Trade Agreement”.

(b) With respect to the Incoming Trade Assets, from and after the Execution Date, Sellers shall afford to Purchaser and Purchaser’s representatives reasonable access (including information requests) pursuant to Section 8.1 to the information in Sellers’ possession regarding the Incoming Trade Assets in order to facilitate Purchaser’s title review and environmental review of the Incoming Trade Assets in accordance with Article 3 (which review may inform Purchaser’s determination of whether any Incoming Trade Asset has substantially equivalent value to the Outgoing Trade Asset, without regard to the applicable deductibles and thresholds set forth in such Article 3).

(c) If the transactions contemplated by any Permitted Trade Agreement are consummated prior to Closing and the applicable Subject Company Group acquires Defensible Title to the Incoming Trade Assets covered by such Permitted Trade Agreement, then Sellers shall give Purchaser written notice within three (3) Business Day following such consummation together with a copy of the applicable conveyances into the Subject Company Groups of such Incoming Trade Assets and all other information available to Sellers regarding such Permitted Trade Agreement.

(d) If the transactions contemplated by any Permitted Trade Agreement are consummated and the Subject Company Groups acquires Defensible Title to the Incoming Trade Assets covered by such Permitted Trade Agreement at or after Closing, Purchaser shall give Sellers written notice within three (3) Business Day following such consummation together with a copy of the applicable conveyances into the Subject Company Groups of such Incoming Trade Assets and all other information available to Purchaser regarding such Permitted Trade Agreement.

121

(e) If any Permitted Trade Agreement is executed prior to Closing, then at Closing: (i) the Unadjusted Purchase Price shall be reduced by an amount equal to Allocated Value of the Outgoing Trade Assets; provided, however, if the effective time of the Permitted Trade Agreement is not the Effective Time or the Outgoing Trade Assets constitute less than all of the applicable Well or DSU for which an Allocated Value is ascribed, then the Allocated Value of the Outgoing Trade Assets shall be deemed to be an amount equal to the Defect Amount, mutatis mutandis, as a result of such Outgoing Trade Assets, without giving effect to the applicable Individual Defect Threshold or the Defect Deductible and (ii) the Unadjusted Purchase Price shall be increased by an amount equal to the Title Benefit Amount attributable to such Incoming Trade Assets, without giving effect to Section 3.2(h) and (iii) Exhibit A will be deemed amended to (A) delete such Outgoing Trade Assets and (B) include such Incoming Trade Assets and such amended Exhibit A shall be used for all purposes under this Agreement.

Section 8.20 Operation of Business of Parent. From the Execution Date until the Closing, except (w) as reasonably necessary or required in order for the Purchaser Parties to perform their respective obligations and covenants set forth herein (x) as expressly contemplated by this Agreement or (y) as expressly consented to by Sellers (which consent shall not be unreasonably delayed, withheld or conditioned), Parent shall not, and shall cause Purchaser Entities not to:

(a) amend or adopt any change to any Governing Documents of Parent;

(b) change in any material respect the material accounting principles, practices or methods of any Purchaser Entity, except as required by the Accounting Principles or statutory accounting requirements or similar principles in non-U.S. jurisdictions;

(c) adopt any plan or agreement of complete or partial liquidation, dissolution, restructuring, recapitalization, merger, consolidation or other reorganization or otherwise effect any transaction whereby any Person or group (other than a Purchaser Entity) acquires more than a majority of the outstanding equity interests of a Purchaser Party; or

(d) agree or commit to do any of the foregoing.

Section 8.21 Listing Application. At the Closing, Parent shall issue the portion of the Equity Purchase Price as determined pursuant to Section 10.3(e) in accordance with all applicable securities Laws and the rules and policies of the NYSE. Without limiting the generality of the foregoing, Parent shall use its reasonable best efforts to complete all such filings with the NYSE and otherwise use its reasonable best efforts to take all such actions as may be reasonably necessary for such portion of the Equity Purchase Price to be approved for listing on the NYSE from and after the time of Closing, subject to official notice of issuance.

Section 8.22 Takeover Laws. If any Takeover Laws or any anti-takeover provision or restriction on ownership in the Governing Documents of Parent is or may become applicable to the transactions contemplated hereby, Parent shall grant such approvals and take all such actions as are necessary or advisable so that such transactions may be consummated as promptly as

122

practicable on the terms contemplated by this Agreement and otherwise act to eliminate or minimize the effects of such statute, regulation or provision in Parent’s Governing Documents on such transactions. As used in this Agreement, “Takeover Laws” means any “moratorium,” “control share acquisition,” “fair price,” “supermajority,” “affiliate transactions,” or “business combination statute or regulation” or other similar state anti-takeover Laws and regulations, including Section 203 of the General Corporation Law of the State of Delaware.

Section 8.23 Financing Cooperation and Efforts.

(a) Prior to the Closing, each Seller shall, and until the Closing Date shall cause its applicable Subject Company Group to, use commercially reasonable efforts to provide timely assistance with Parent’s efforts to arrange and obtain the Financing in connection with the transactions contemplated by this Agreement as is reasonably requested by Parent, which assistance may include: (i) each Subject Company using its commercially reasonable efforts to make available to Parent information with respect to the preparation of the Marketing Material and rating agency presentations and reasonable and customary due diligence and drafting sessions associated therewith, which Marketing Material and presentations and the preparation thereof, for the avoidance of doubt and in spite of any such required participation and assistance from any Subject Company, shall be the sole responsibility of Parent; (ii) making available to Parent and any financing sources such other financial and operational information reasonably requested by Parent or any financing sources as promptly as reasonably practicable, including any financial statements, information, and Purchaser Financial Statements required pursuant to Section 8.12; (iii) making available to Parent such other customary documents and financial and pertinent information regarding the Subject Company Groups and Affiliates thereof as may be reasonably requested by Parent or necessary for Parent or the Parent’s Representatives to prepare all pro forma financial statements reasonably requested by Parent in connection with the Financing, including revisions that reflect comments, waivers or preclearance provided to Parent or its Affiliates by the staff of the SEC (it being understood that no Subject Company nor any of the Subsidiaries of any Subject Company, or any of their respective officers, directors, employees, accountants, legal counsel, or other Subject Company Representative shall be responsible for, and Parent shall be solely responsible for, preparation of pro forma financial statements, other than the provision of “comfort” by the independent auditors of the Subject Company Group solely to the extent reasonable and customary in the case of target company financial statements and related adjustments, and the provision of customary management representation letters to such independent auditors for such purpose); provided that no Subject Company nor any of their respective Subsidiaries or Subject Company Representatives shall be required to provide any information or assistance relating to (A) the proposed debt and equity capitalization that is required for such pro forma financial information or assumed interest rates and fees and expenses relating to such debt and equity capitalization, (B) any post-Closing or pro forma cost savings, synergies, capitalization, ownership or other pro forma adjustments desired to be incorporated into any information used in connection with the Financing or (C) any information related to Parent or any of its Subsidiaries or any adjustments that are not directly related to the acquisition of the Subject Companies; (iv) delivering customary authorization letters authorizing the distribution of Marketing Material to prospective financing sources and other investors; (v) furnishing Parent and any financing sources promptly, and, in any event, at least four (4) Business Days prior to the Closing Date, with all documentation and other information in respect of the Subject Company Groups or their Affiliates that Parent or any

Parent shall be permitted to disclose any information to (A) any financing sources subject to their confidentiality obligations under the Financing documents and the definitive documentation evidencing the Financing and (B) otherwise to the extent reasonably necessary and consistent with customary practices in connection with the Financing subject to (other than in connection with any disclosure pursuant

124

to a prospectus, offering memorandum or other marketing materials in connection with an offering of debt or equity securities) customary confidentiality arrangements. Any such cooperation shall be provided at Parent’s expense for reasonable and documented third party fees and expenses. Notwithstanding anything in this Agreement to the contrary, except to the extent that any such failure is caused by a willful and intentional breach by Sellers or the Subject Companies of this Section 8.23(a), (i) in no event will any failure by Sellers or the Subject Companies to comply with this Section 8.23(a) be used by the Purchaser Parties as a basis to (A) terminate this Agreement, (B) assert the failure of any of Purchaser Parties’ conditions to Closing to be satisfied, (C) assert that Sellers are not entitled to terminate this Agreement under the circumstances set forth in Section 12.1(e) or (D) assert any claim for Damages under this Agreement.

(b) Notwithstanding anything to the contrary in Section 8.23(a), (i) no Seller, 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 8.23(a)); (ii) no obligation of any Subject Company or any of its Affiliates or any of their respective equityholders, members or Subject Company 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 8.23(a)); (iii) no Subject Company nor any of their respective Affiliates or any of their respective equityholders, members or Subject Company 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 8.23(a); (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 commercially 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 Seller, Subject Company or any of their respective Subsidiaries is required to create, provide, update or have audited or reviewed any financial statements or other information except for those explicitly contemplated by Section 8.12 and Section 8.23(a). 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 8.12 and Section 8.23(a) and (vi) no such cooperation shall be required to the extent

125

any Seller or any member of any Subject Company Group has to disclose or provide any Excluded Records. 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 counsel, contractor or advisor) to the extent incurred by such Seller and/or Subject Company and its Subsidiaries and any other Subject Company Representatives in connection with the Financing (including related to compliance with Section 8.12), including the cooperation of such Seller and the Subsidiaries thereof contemplated by this Section 8.23, and shall indemnify and hold harmless Sellers, Subject Companies and the respective Subsidiaries thereof and the Subject Company Representatives from and against any and all losses suffered or incurred by any of them in connection with their compliance with this Section 8.23, the arrangement of the Financing or any 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 any Subject Company Representative.

Section 8.24 Litigation Support.

(a) As and to the extent requested by any Party or its Affiliates after Closing, the Other Party shall, and shall cause its Affiliates and then-current officers and employees (with respect to such Other Party, such Other Party’s “Litigation Support Group”) to, reasonably cooperate with such requesting Party and its Affiliates in the prosecution, mitigation, defense or settlement of the Specified Litigation Matter, including by providing such requesting Party, its Affiliates and its and their legal counsel, as applicable, reasonable access, to the extent such access is within the control of such Other Party, during normal business hours to current officers, directors, employees, agents, records, documents, data and other information as such requesting Party or Affiliate thereof may reasonably request, to the extent maintained by or under the possession or control of such Other Party or its Litigation Support Group; provided that such Other Party and its Litigation Support Group may restrict the foregoing access or the provision of such information to the extent that, it is not germane to the requesting Party’s ability to prosecute, mitigate, conduct its defense or settlement of the matters described in this Section 8.24(a), and that upon advice of counsel, (a) applicable Law or 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 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 Other Party or its Litigation Support Group restricts access or withholds information on the basis of the foregoing clauses (a) through (c), such Other Party 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 Other Party or its Litigation Support Group, inform the requesting Party and its Affiliates 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

126

or disclosure of the relevant information in a manner that does not have such restrictions, or otherwise provide the information. The requesting Party shall reimburse such Other Party 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 8.24(a) (including reasonable fees and expenses of legal counsel, if applicable).

(b) From and after the Execution Date, the Parties agree to be bound by the terms of Schedule 8.24(b) with respect to the matters set forth therein.

(c) Nothing in this Section 8.24 shall be construed to waive, amend or abridge any rights to indemnification of the Purchaser Parties under Section 13.2.

Section 8.25 Confidentiality.

(a) The terms of the Confidentiality Agreement are hereby incorporated by reference, and the Confidentiality Agreement shall continue in full force and effect in accordance with its terms until the Closing, at which time the Confidentiality Agreement shall terminate; provided that, solely as it relates to any “Excluded Assets” and “Excluded Records” (as defined herein), the term of the Confidentiality Agreement shall be extended until the date that is eighteen (18) months after the Closing Date. In the event a provision contained in the Confidentiality Agreement conflicts with a provision contained in this Agreement, the provision contained in this Agreement shall control.

(b) Sellers, for themselves and on behalf of their Affiliates, acknowledge that, after the Closing, Purchaser and its Affiliates would be irreparably damaged if any confidential information regarding Purchaser, its Affiliates, the Subject Company Group, the Business, the Assets and the operation thereof (including information regarding the activities, finances, properties and other assets, marketing, pricing, suppliers, customers, licensors and licensees, and any information or reports provided by or on behalf of Purchaser in connection with its due diligence investigation of the Assets prior to Closing) were disclosed to or utilized on behalf of any other Person. Sellers, for themselves and on behalf of their Affiliates, covenant and agree that, for a period of eighteen (18) months following the Closing, they will not, without the prior written consent of Purchaser, disclose or permit to be disclosed or use or permit to be used in any way any such confidential information unless (i) it receives a request or is compelled to disclose such confidential information by judicial or administrative process or by other Order issued by a Governmental Authority, (ii) such disclosure is required by the rules of any applicable stock exchange or regulatory or self-regulatory organization or other applicable Law; (iii) such disclosure is to its accountants, attorneys, advisors and other professional consultants or Non-Recourse Persons (in each case, to the extent that each is subject to similar confidentiality obligations with such Seller); (iv) such disclosure is necessary in connection with the filing of Tax Returns or claims for refund or in defending, prosecuting or otherwise conducting any examination, audit or administrative or judicial Action regarding any Tax Return or Taxes; (v) such disclosure is made in connection with the enforcement, defense or settlement of such Seller’s rights and obligations under this Agreement, the Transaction Documents or as may be reasonably necessary to effect the transactions under this Agreement or the Transaction Documents; (vi) such information is lawfully in the possession of the Third Party recipient other than as a result of a breach of this Section 8.25 or (vii) such information is generally available to

127

Third Parties other than as a result of a breach of this Section 8.25. Sellers, for themselves and on behalf of their Affiliates, as applicable, shall give Purchaser prior written notice of any disclosure pursuant to clause (i) above and cooperate with Purchaser, at Purchaser’s expense, to limit or obtain confidential treatment of the information so required to be disclosed. Upon the expiration of such period of eighteen (18) months following the Closing, Sellers shall destroy or return to Purchaser copies of any and all Records retained by Sellers pursuant to Section 8.8, except to the extent such Records are needed to enforce or comply with Sellers’ rights, obligations or covenants under this Agreement, including under Article 11 and Article 13.

Section 8.26 Form S-3 Eligibility. Until the filing of the Resale Shelf pursuant to the Registration Rights Agreement, Parent shall use its reasonable best efforts to not take any action, or fail to take any action, which action or failure would reasonably be expected to cause Parent to be ineligible to file a Registration Statement on Form S-3 promulgated under the Securities Act (or any successor form).

Section 8.27 Escrow Matters.

(a) Each of Sellers and Purchaser will use their best efforts to execute and deliver, and to take such reasonable steps as are necessary to satisfy any and all reasonable requirements for the Escrow Agent to execute and deliver, the Escrow Agreement within one (1) Business Day after the Execution Date.

(b) Except as otherwise agreed by Purchaser and Sellers in writing, the Parties agree that the Escrow Agent shall report all interest or other income earned on any amounts held by the Escrow Agent (including, as applicable, the Performance Deposit, Holdback Amount, Defect Deposit and the Additional Lease Deposit) pursuant to the Escrow Agreement (“Escrow Earnings”) to the IRS, or any other applicable taxing authority, on IRS Form 1099 (or other appropriate form) as required by applicable Law, as follows: (i) with respect to the Escrow Earnings, to the extent earned prior to Closing, as income earned by Purchaser whether or not such Escrow Earnings had been disbursed during such period, in accordance with Treasury Regulation Section 1.468B-7(c), and (ii) with respect to the Escrow Earnings, to the extent earned after the Closing, if any, (A) as attributable to the Holdback Amount, as income earned by Sellers (pro rata in accordance with their respective Percentage Share), (B) attributable to the Additional Lease Deposit, as income earned by Sellers (in proportion to their respective ownership of the Accepted Additional Leases to which the amounts included in the Additional Lease Deposit relate, as designated by Sellers) and (C) attributable to the Defect Deposit, as income earned by Purchaser, in each case, whether or not such Escrow Earnings had been disbursed during such period, in accordance with Proposed Treasury Regulation Section 1.468B-8(h)(2) (February 1, 1999), as such Proposed Treasury Regulations may be amended or modified, including upon the issuance of temporary or final regulations. With respect to the Escrow Earnings attributable to the Holdback Amount and the Additional Lease Deposit, any interest or other income allocated to Sellers will constitute “stated interest” within the meaning of Sections 453, 483 and 1272-1275 of the Code and the Treasury Regulations. The Parties shall cooperate in good faith to provide joint written instructions to the Escrow Agent that contain instructions consistent with this Section 8.27(b) (including, if needed, the date upon which such tax reporting change, in accordance with, and as referenced in, the immediately preceding sentence, is required to take effect). Neither Purchaser nor Sellers shall take any position for U.S. federal (or applicable state and local) income tax purposes that is inconsistent with the provisions of this Section 8.27(b).
