Seller shall have a reasonable opportunity, but not the obligation, to cure prior to the

31

date that is ninety (90) days after the delivery of the Defect Notice, any Title Defect asserted by Purchaser pursuant to this Section 3.1(b).

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

Section 3.2 Defects; Adjustments.

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

(i) a description of the alleged Defect;

(ii) the Well or DSU subject to such alleged Defect;

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

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

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

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

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

(i) a description of the alleged Title Benefit;

32

(ii) the Well or DSU subject to such alleged Title Benefit;

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

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

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

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

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

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

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

(iii) if a Title Defect as to the Subject Formation affecting any Well or DSU represents a negative discrepancy between (A) the actual Net Revenue Interest for the Subject Formation as to such Well or DSU and (B) the “Net Revenue Interest” stated on Exhibit A-2 or Exhibit A-3, as applicable, for the Subject Formation as to such Well or DSU, then the Defect Amount shall be equal to the product of (1) the Allocated Value of the Subject Formation as to such Well or DSU multiplied by (2) a fraction, the numerator of which is (x) the remainder of (a) the “Net Revenue Interest” stated on Exhibit A-2 or Exhibit A-3, as applicable, for the Subject Formation as to such Well or DSU minus (b) the actual Net Revenue Interest as to the Subject Formation as to such Well or DSU, and the denominator of which is (y) the “Net Revenue Interest” stated on Exhibit A-2 or Exhibit A-3, as applicable, for the Subject Formation as to such Well or DSU; provided that if the Title Defect does not affect the “Net Revenue Interest” stated on Exhibit A-2 or Exhibit A-3, as applicable, for the Subject Formation as to such Well or DSU throughout its entire productive life,

33

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 as to the Subject Formation affecting any DSU represents a negative discrepancy between (A) the actual Net Mineral Acres for the Subject Formation as to such DSU and (B) the Net Mineral Acres for such DSU stated on Exhibit A-3, then the Defect Amount shall be equal to the product obtained by multiplying the absolute value of such difference between such Net Mineral Acre amounts by the per-acre value based on the aggregate Allocated Values of the Hydrocarbon leases in such DSU;

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

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

(vii) 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

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

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

34

(i) if a Title Benefit applicable to the Subject Formation as to any Well or DSU represents a positive discrepancy between (A) the actual Net Revenue Interest for the Subject Formation as to such Well or DSU and (B) the Net Revenue Interest percentage stated on Exhibit A-2 or Exhibit A-3, as applicable, for the Subject Formation as to such Well or DSU, and in such case there is a proportionate increase in the actual Working Interest with respect to the Subject Formation as to such Well or DSU, as applicable, from the Working Interest stated on Exhibit A-2 for Seller with respect to the Subject Formation or for such Well or Exhibit A-3 with respect to the Subject Formation for such DSU, as applicable, then the Title Benefit Amount shall be equal to the product of (1) the Allocated Value of the Subject Formation as to such Well or DSU multiplied by (2) a fraction, the numerator of which is (x) the remainder of (a) the actual Net Revenue Interest of the Subject Formation as to such Well or DSU minus (b) the Net Revenue Interest percentage stated on Exhibit A-2 or Exhibit A-3, as applicable, for the Subject Formation as to such Well or DSU, and the denominator of which is (y) the Net Revenue Interest percentage stated on Exhibit A-2 or Exhibit A-3, as applicable, for the Subject Formation as to such Well or DSU; provided that if the Title Benefit does not affect the Net Revenue Interest percentage stated on Exhibit A-2 or Exhibit A-3, as applicable, for the Subject Formation as to such Well or 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 Well or DSU so affected, the portion of Seller’s interest in the Well or DSU affected by the Title Benefit, the legal effect of the Title Benefit, the potential positive economic effect of the Title Benefit over the life of the affected Well or DSU, the values placed upon the Title Benefit by Purchaser and Seller and such other reasonable factors as are necessary to make a proper evaluation and determination of such value.

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

(i) except as otherwise provided in this Section 3.2(f)¸there shall be no adjustments to the Unadjusted Purchase Price under Section 3.2(g) for any Defect unless (A) the finally determined or agreed Defect Amount for such Defect exceeds the Individual Defect Threshold and (B) the aggregate of all finally determined or agreed Defect Amounts for all such Defects exceeds the Aggregate Defect Threshold; (it being agreed that the Individual Defect Threshold and Aggregate Defect Threshold each represent a threshold and not a deductible);

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

(iii) notwithstanding anything herein to the contrary, neither the Individual Defect Threshold nor Aggregate Defect Threshold shall apply to any recourse under this Agreement or the Conveyances with respect to any Special Warranty Defect; and

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

35

Defect Amounts associated with such Environmental Defect that is common across multiple Assets may be aggregated for purposes of meeting the Individual Defect Threshold.

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

(i) subject to satisfaction of the Individual Defect Threshold and Aggregate Defect Threshold pursuant to Section 3.2(f), all Assets subject to any Defects shall be conveyed to Purchaser at Closing and the Unadjusted Purchase Price shall be decreased by the sum of (x) the aggregate finally determined or agreed Defect Amounts attributable to all such finally determined or agreed Title Defects hereunder minus (y) the aggregate finally determined or agreed Title Benefit Amounts attributable to all such finally determined or agreed Title Benefits hereunder, plus the aggregate finally determined or agreed Defect Amounts attributable to all such finally determined or agreed Environmental Defects hereunder; and

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

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

(i) Disputed Defects; Defect Escrow.

(i) Seller and Purchaser shall use good faith efforts to agree prior to Closing (and if applicable for any Title Defects that Seller is deemed to have elected to attempt to cure after Closing, prior to the Cure Deadline) and after Closing 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 Seller and Purchaser are unable to agree on the validity and determination of any Title Benefit, Title Benefit Amount, Defect or Defect Amount (or the cure thereof) prior to the Closing Date, Purchaser shall deposit with the Escrow Agent a portion of the Adjusted Purchase Price equal to the Defect Escrow Amount in accordance with Section 9.3(c), 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 and the affected Assets subject to such Defects shall nonetheless be conveyed to Purchaser at Closing.

36

(ii) If Seller and Purchaser are unable to agree on the interpretation and effect of this Article 3, the existence, cure, Remediation, or amount of (A) any disputed Title Benefits, Title Benefit Amounts, Title Defects, or associated Defect Amounts (each, a “Title Disputed Matter”) by the date that is ten (10) Business Days after the expiration of the Cure Deadline, or (B) any disputed Environmental Defects or Defect Amounts associated with Environmental Defects (each, an “Environmental Disputed Matter” and, together with the Title Disputed Matters, the “Disputed Defect Matters”) by the Closing Date, then, subject to Section 3.2(d), 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 expiration of the Cure Deadline, each of Seller and Purchaser shall submit in writing its proposed resolution of each Title Disputed Matter to a neutral title attorney with at least fifteen (15) years’ experience in oil and gas titles involving properties in the regional area of the Assets subject to the Disputed Defect Matters and mutually acceptable to Seller and Purchaser, or absent such agreement during the ten (10) Business Day period, by the Houston, Texas office of the AAA (the “Title Referee”) and (2) the Closing Date, each of Seller and Purchaser shall submit in writing its proposed resolution of each Environmental Disputed Matter to a neutral nationally recognized independent environmental consulting firm mutually acceptable to Seller and Purchaser or, absent such agreement during the ten (10) Business Day period, by the Houston, Texas office of the AAA (the “Environmental Referee” and, together with the Title Referee, each a “Defect Referee”). If a 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. A Defect Referee shall not have worked as an employee or outside counsel 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) Within ten (10) Business Days after the selection of the applicable Defect Referee, the Parties shall provide to such Defect Referee only the documents and materials described in this Section 3.2(i)(iii), as applicable (it being the intention of the Parties that any Party submitting a Defect Notice or Title Benefit Notice shall only be able to submit to the applicable Defect Referee the information, reports, opinions and materials included with or provided as part of such Defect Notice or Title Benefit Notice):

(A) each Defect Notice and all documentation provided therewith with respect to each disputed Defect;

(B) each Title Benefit Notice and all documentation provided therewith with respect to each disputed Title Benefit; and

(C) this Article 3, Exhibit A-2, and Exhibit A-3, together with any definitions of terms used in this Article 3 and such Exhibits and Schedule, but no other provisions of this Agreement.

(iv) 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. The applicable Defect Referee’s determination shall be made within thirty (30) days after submission of the matters in dispute and shall be final and binding upon the Parties, without a right of appeal. Neither Purchaser nor Seller may have any

37

ex parte communications with 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 and may consider such other matters as in the opinion of the applicable Defect Referee are necessary or helpful to make a determination; provided, however, in determining the existence or amount of any Defect or Defect Amount, Purchaser may not submit any evidence, records, materials, data or information that was not included in a valid Defect Notice delivered to Seller by the Defect Deadline and neither Purchaser nor Seller shall submit any evidence, records, material, data or information that was not included in Seller’s 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.

(v) In rendering his or her award, the applicable Defect Referee shall be limited to selecting either Seller’s position or Purchaser’s position on each of the Disputed Defect Matters. 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 with respect to any Disputed Defect Matters 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 13.3. The applicable Defect Referee shall act as an expert for the limited purpose of determining the interpretation and effect of this Article 3 to resolve any Disputed Defect Matter in accordance with this Section and shall not award damages, interest, or penalties to any Party with respect to any matter. The fees, costs and expenses of the applicable Defect Referee shall be borne by Seller, on the one hand, and by Purchaser, on the other hand, based upon the percentage that the amount not ultimately awarded to such Party by the applicable Defect Referee bears to the amount actually contested by such Party with respect to all applicable disputed matters. Each Party shall pay its own legal fees and other costs of presenting its case.

(vi) Promptly, but in no event later than three (3) Business Days after such Disputed Defect Matter(s) has been mutually agreed by the Parties or finally determined by a Defect Referee, the Parties shall deliver joint written instructions directing the Escrow Agent to disburse from the Escrow Account the Title Benefit Amount or Defect Amount with respect thereto to the Party entitled to such amount pursuant to the terms of this Agreement, together with any interest accrued on such amount under the terms of the Escrow Agreement.

Section 7.4 Consents to Assignment.

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

(b) In cases in which the Asset subject to a Required Consent requirement is an Oil and Gas Property and the Required Consent is not obtained by Closing, then either Party may elect to exclude the Oil and Gas Property subject to such Required Consent (along with any other Assets reasonably necessary or desirable for the ownership or operation of such Oil and Gas Property), in which event, (i) the Unadjusted Purchase Price shall be reduced by the Allocated Value of such excluded Oil and Gas Property and other Assets, (ii) such excluded Oil and Gas Property and other Assets shall be deemed to be deleted from Exhibit A and added to Schedule 1.1(b), and (iii) such excluded Oil and Gas Property and other Assets shall constitute Excluded Assets for all purposes hereunder.

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

(b) If any Preferential Right as to any Assets is validly exercised prior to Closing, then (i) the Unadjusted Purchase Price shall be reduced by the Allocated Value of such Asset, (ii) such Assets shall be deemed to be deleted from Exhibit A and added to Schedule 1.1(b), and (iii) such Assets shall constitute Excluded Assets for all purposes hereunder; provided, however, in the event the holder of any Preferential Right as to any Assets validly exercises such Preferential Right prior to Closing but refuses or fails to consummate the purchase of such Assets on or before the Cut-Off Date, then (A) Seller shall promptly

54

convey the applicable Assets to Purchaser, (B) the Parties shall deliver all instruments and documents that would have been required under the terms hereof to be delivered at Closing with respect to such Assets, (C) Purchaser shall, simultaneously with the conveyance of the applicable Assets, pay the amount of any previous deduction from the Unadjusted Purchase Price (subject to all other applicable adjustments with respect to such Assets under Section 2.4) to Seller, and (D) such Assets shall no longer be deemed to be (1) deleted from Exhibit A, (2) added to Schedule 1.1(b), or (3) Excluded Assets for any purposes hereunder.

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

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

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

55

Purchase Price by the cost and expense to repair or replace the Assets affected by such Casualty Loss. If the Parties are unable to agree on the amount of any reduction to the Unadjusted Purchase Price under this Section 7.6 or the preceding sentence, Seller’s good faith and reasonable estimate shall be used for the purposes of adjusting the Unadjusted Purchase Price at Closing, subject to final adjustment in accordance with Section 2.4.

The Purchaser shall promptly reimburse Seller for all reasonable Third Party costs and expenses incurred by Seller and its Affiliates in compliance with this Section 7.15.

(d) 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 Seller of this Section 7.15, in no event will any

The Holdback Amount shall be held by the Escrow Agent and disbursed by Escrow Agent after the Closing in accordance with this Section 7.16 and the Escrow Agreement.

(c) With respect to each claim for indemnification asserted by Purchaser against Seller pursuant to Section 12.3, any claim asserted by Purchaser pursuant to the special warranty of Defensible Title in the Conveyance, or if Seller has not timely delivered any amounts owing to Purchaser pursuant to Section 2.6, then from and after the Closing Date up to the Holdback Release Date (subject to the limitations set forth in this Section 7.16), upon final resolution or determination of such claim by the Parties or in accordance with this Agreement, Purchaser and Seller shall jointly instruct Escrow Agent to disburse to Purchaser the amount set forth in such joint instruction, which will be that portion of the Holdback Amount being held in the Escrow Account as would satisfy such indemnity claim, special warranty claim, or other claim in respect of a Holdback Matter.

61

which Seller serves as operator. Seller shall perform the Accounting Services with the degree of care, skill and diligence with which it has performed similar services for the Oil and Gas Properties and the related operations prior to the Closing Date. The quality of Accounting Services provided by Seller is not required to be higher than the quality of the same or similar services that Seller has historically provided with respect to the Oil and Gas Properties. In no event shall Seller have any liability to Purchaser hereunder in connection with the performance of the Accounting Services except to the extent of the actual fraud, gross negligence, or willful misconduct of Seller (including any employee of Seller performing any of the Accounting Services) (“Seller Indemnification Obligations”).

Section 7.19 Jana M Well.

(g) In the event that Seller fails to obtain the assignment of leases to Seller under the Farmout within a reasonable period to be mutually agreed upon by Seller and Purchaser, (i) Purchaser shall reassign its entire right, title and interest in the Jana M Leases and the right to obtain an assignment and conveyance of an interest in the Additional JM Leases and the Jana M Well, (ii) Seller and Purchaser shall each deliver to the Escrow Agent duly executed copies of joint written instructions, instructing the Escrow Agent to disburse the Jana M Deposit to Purchaser; provided, that Purchaser may, in its sole discretion, elect to apply the Jana M Deposit to its share of drilling and completion costs for the initial well to be drilled under another DSU, to be determined by mutual agreement of Purchaser and Seller, in which case Purchaser and Seller shall instruct the Escrow Agent to disburse the Jana M Deposit accordingly; and

67

attributable to (x) any Tax period beginning at or after the Effective Time and (y) the portion of any Straddle Period beginning at the Effective Time.

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

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

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

Section 10.2 Transfer Taxes and Recording Fees.

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

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

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

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

ARTICLE 11

TERMINATION

Section 11.1 Termination. This Agreement may be terminated at any time prior to Closing (the date of any permitted termination of this Agreement under this Section 11.1, the “Termination Date”):

(a) by the mutual prior written consent of Seller and Purchaser;

69

(b) by Seller or Purchaser upon written notice to the other Party, if Closing has not occurred on or before the Target Closing Date (the “Initial Outside Date”); or

(c) by Seller, upon written notice to Purchaser, if Purchaser has not funded the Deposit within two (2) Business Days of the Execution Date as provided in Section 2.3;

provided, however, that no Party shall be entitled to terminate this Agreement under Section 11.1(b) if (i) the Closing has failed to occur as a result of the breach or failure of any of such Party’s representations, warranties, or covenants hereunder, including, if and when required, such Party’s obligations to consummate the transactions contemplated hereunder at Closing and or (ii) a Party is entitled to and is enforcing its right to specific performance of this Agreement under Section 11.2(b) or Section 11.2(c) below.

Section 11.2 Effect of Termination.

(a) If this Agreement is terminated pursuant to Section 11.1, this Agreement shall become void and of no further force or effect (except for the provisions of Article 1, Section 2.3, Section 5.12, Article 6, Section 7.1(b), Section 7.1(c), Section 7.1(d), Section 7.10, Article 11, and Article 13, all of which shall survive and continue in full force and effect indefinitely). The Confidentiality Agreement shall survive any termination of this Agreement, and, upon such termination, the term thereof shall be deemed automatically extended to run until the date that is eighteen (18) months from the date of such termination.

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

(c) In the event that (i) all conditions precedent to the obligations of Purchaser set forth in Section 8.2 have been satisfied or waived (to the extent waivable) in writing by Purchaser (or would have been satisfied except for the breach or failure of any of Purchaser’s representations, warranties or covenants hereunder); and (ii) the Closing has not occurred solely as a result of the breach or failure of any of Purchaser’s representations, warranties, or covenants hereunder, including, if and when required, Purchaser’s obligations to consummate the transactions contemplated hereunder at Closing, then Seller shall be entitled, as the sole and exclusive remedy of the Seller Group against any member of the Purchaser Group for the failure to consummate the transactions contemplated hereunder at the Closing, to terminate this Agreement and receive an amount of the Deposit equal to the actual, documented out-of-pocket costs and expenses of Seller incurred in connection with, or in preparation for, the negotiation, diligence, performance and consummation of the transactions contemplated hereunder at Closing, for the sole account and use of Seller as liquidated damages hereunder. Seller and Purchaser acknowledge and agree that (i) Seller’s actual damages upon the event of such a termination are difficult to ascertain with any certainty,

70

(ii) the foregoing is a fair and reasonable estimate by the Parties of such aggregate actual damages of Seller, and (iii) such liquidated damages do not constitute a penalty.

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

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

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

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

Section 12.5 Indemnification Actions. All claims for indemnification under Article 12 shall be asserted and resolved as follows:

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

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

(c) In the event that any claim for indemnification set forth in any Claim Notice is based upon a claim by a Third Party against the Indemnified Person (a “Third Party Claim”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim in such Indemnified Person’s possession or control; provided that the failure of any Indemnified Person to give notice of any Third Party Claim as provided in this Section 12.5 shall not relieve the Indemnifying Party of its obligations under this Article 12 except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise prejudices the Indemnifying Party’s ability to defend against the Third Party Claim. In the event that the claim for indemnification is based upon an alleged inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was allegedly inaccurate or breached.

(d) Subject to Section 12.5(f), in the case of a claim for indemnification based upon any Third Party Claim, the Indemnifying Party shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies (i) in the case of Seller, Purchaser’s right to indemnity from Seller in respect of such Third Party Claim as provided in this Article 12 or (ii) in the case of Purchaser, its obligation to defend the Indemnified Person against such Third Party Claim under this Agreement. The Indemnified Person is authorized, prior to and during such thirty (30) day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party. If the Indemnifying Party fails to notify the Indemnified Person within such thirty (30) day period regarding whether the Indemnifying Party admits or denies (A) in the case of Seller, Purchaser’s right to indemnity from Seller in respect of such Third Party Claim as provided in this Article 12 or (B) in the case of Purchaser, its obligation to defend the Indemnified Person against such Third Party Claim under this Agreement, then until such date as the Indemnifying Party admits or it is finally determined by a non-appealable judgment that such right or obligation exists, the Indemnified Person may file any motion, answer or other pleading, settle any Third Party Claim or take any other action that the Indemnified Person deems necessary or appropriate to protect its interest, regardless of whether the Indemnifying Party is prejudiced or adversely impacted by any such actions.

74

(e) If (x) Seller admits Purchaser’s right to indemnity from Seller in respect of such Third Party Claim as provided in this Article 12 or (y) Purchaser admits its obligation to defend the Indemnified Person against such Third Party Claim under this Agreement, as applicable, then the applicable Indemnifying Party shall have (i) the right and obligation to diligently prosecute and control the defense of such Third Party Claim, if Purchaser is the Indemnifying Party, at the sole cost and expense of Purchaser, and if Seller is the Indemnifying Party, at the sole cost and expense of Seller, and (ii) have full control of such defense and proceedings, including any compromise or settlement thereof unless the compromise or settlement includes the payment of any amount by, the performance of any obligation by, or the limitation of any right or benefit of, the Indemnified Person, in which event such settlement or compromise shall not be effective without the consent of the Indemnified Person, which shall not be unreasonably withheld or delayed. If requested by the Indemnifying Party, the Indemnified Person agrees at the cost and expense of the Indemnifying Party to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest; provided, however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person. The Indemnified Person may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 12.5(e), provided that the Indemnified Person may file initial pleadings as described in the last sentence of Section 12.5(d) if required by court or procedural rules to do so within the thirty (30) day period in Section 12.5(d). An Indemnifying Party shall not, without the written consent of the Indemnified Person, settle any Third Party Claim or consent to the entry of any judgment with respect thereto that (A) does not result in a final resolution of the Indemnified Person’s liability with respect to the Third Party Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person from all further liability in respect of such Third Party Claim) or (B) may materially and adversely affect the Indemnified Person (other than as a result of money damages covered by the indemnity).

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

75

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

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

Section 12.6 Express Negligence/Conspicuous Manner. WITH RESPECT TO THIS AGREEMENT, BOTH PARTIES AGREE THAT THE PROVISIONS SET OUT IN THIS ARTICLE 12 AND ELSEWHERE IN THIS AGREEMENT COMPLY WITH THE REQUIREMENT, KNOWN AS THE EXPRESS NEGLIGENCE RULE, TO EXPRESSLY STATE IN A CONSPICUOUS MANNER TO AFFORD FAIR AND ADEQUATE NOTICE THAT THIS AGREEMENT HAS PROVISIONS REQUIRING PURCHASER TO BE RESPONSIBLE FOR THE NEGLIGENCE (WHETHER GROSS, SOLE, JOINT, ACTIVE, PASSIVE, COMPARATIVE OR CONCURRENT), STRICT LIABILITY, OR OTHER FAULT OF MEMBERS OF THE SELLER GROUP.

Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective permitted successors and assigns.

NEWS RELEASE

SANDRIDGE ENERGY, INC. ANNOUNCES ENTRY INTO DEFINITIVE AGREEMENT

TO ACQUIRE ASSETS IN THE WESTERN ANADARKO BASIN

AND ENTRY INTO JOINT DEVELOPMENT AGREEMENT

Oklahoma City, Oklahoma, July 29, 2024 /PRNewswire/ – SandRidge Energy, Inc. (the “Company” or “SandRidge”) (NYSE: SD) today announced the entry into a definitive agreement to acquire certain producing assets and leasehold interests in the Cherokee play of the Western Anadarko Basin for cash consideration of $144 million, before customary purchase price adjustments. The Company also entered into a Joint Development Agreement (“JDA”) governing its participation in the future development of certain of the acquired leasehold interests.

Acquisition Highlights

Grayson Pranin, SandRidge’s President & Chief Executive Officer, commented on the acquisition:

“We’re excited to expand our footprint in the Mid-Continent by upgrading our inventory through the Cherokee Shale play in the Western Anadarko Basin. These assets bolster our base production and cash flow profile by immediately adding higher oil content while providing access to a successful drilling campaign through joint development of the assets. We’re looking forward to participating in new high-return drilling and completion projects and taking over operatorship of the new wells, allowing us to apply SandRidge’s low-cost lease operating expertise to the new assets.

This transaction allows us to boost future production and cash flow levels, while preserving our strong balance sheet and planned capital return program. The undeveloped assets are focused in a proven and highly productive area in Roger Mills County, Oklahoma and are self-funding on a standalone basis.

Finally, the acquired producing assets and DSUs flange up with areas where we’ve been recently investigating the potential for new SandRidge-operated drilling opportunities. As we operate and jointly develop the acquired assets, our team will be well positioned to evaluate and execute on future organic growth opportunities.”

Legal Advisor

Winston & Strawn LLP is serving as SandRidge’s legal advisor for the transaction.
