The limitations described in this paragraph will not apply to the extent of Seller’s breach of its representations under Section 14(a), Section 14(b), or Section 14(i) or fraud on the part of the Seller; provided, however that Seller’s obligation to indemnify the Buyer for a breach of Seller’s representations and warranties contained in this Agreement, the Specified Obligations, and Seller’s breach of, or default under, any of its covenants or obligations under this Agreement shall be capped at the Purchase Price.

(C) NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT, FROM AND AFTER CLOSING, THIS SECTION 8 CONTAINS BUYER’S EXCLUSIVE REMEDY AGAINST SELLER AND ANY MEMBER OF THE SELLER GROUP WITH RESPECT TO BREACHES OF THE REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS OF THE PARTIES IN THIS AGREEMENT AND OTHERWISE WITH RESPECT TO THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT AND THE ASSETS.

(F) Payments by an indemnifying party in respect of any indemnified loss hereunder shall be limited to the amount of any liability or damage that remains after deducting therefrom any insurance proceeds and any indemnity, contribution or other similar payment actually received by the indemnified party in respect of any such claim.

9. Due Diligence Review; Access to Files. Buyer shall have until the Closing date to examine the Assets, production records, operational records and the Records, and Seller shall allow Buyer reasonable access to its files relating to the Assets and the Records in Seller’s possession at its offices and will use commercially reasonable efforts to provide Buyer a reasonable opportunity to inspect the Assets and the Records, in each case, during normal business hours following reasonable prior written notice. Notwithstanding the provisions of this Section 9, Buyer’s investigation shall be conducted in a manner that minimizes interference with the operation of the business of Seller and any applicable third parties.

10. Specific Performance. Prior to Closing, Seller and Buyer acknowledge that the remedies at law or in equity of Seller and Buyer for a breach or threatened breach of this Agreement may be inadequate and, in recognition of this fact, either Party, without posting any bond or the necessity or proving the inadequacy as a remedy of monetary damages, and in addition to all other remedies that may be available, shall be entitled to obtain equitable relief in the form of specific performance, a temporary restraining order, a temporary or permanent injunction or any other equitable remedy that may then be available.

11. Title Defect Notices; Title Defect Adjustments.

(a) Certain Title Defect Terms. Appendix I is hereby incorporated by reference.

(b) Title Defect Notices. On or before 5:00 p.m., Central Time, on the date that is seven (7) days prior to the Closing date (the “Defect Claim Date”), Buyer shall deliver claim notices to Seller meeting the requirements of this Section 11 (collectively, the “Title Defect Notices,” and each individually, a “Title Defect Notice”) setting forth any matters that, in Buyer’s reasonable and good faith opinion, constitute Title Defects. For all purposes of this Agreement and notwithstanding anything herein to the contrary, Buyer shall be deemed to have waived, and Seller shall have no liability for, any Title Defect or other title matter that Buyer fails to assert as a Title Defect in a sufficient Title Defect Notice received by Seller on or before the Closing date. To be effective, each Title Defect Notice shall be in writing and shall include: (i) a description of the alleged Title Defect, (ii) identification of the individual Well (and any associated Assets) affected by the Title Defect (each such Asset, a “Title Defect Property”), (iii) the Allocated Value of each Title Defect Property, (iv) supporting documents reasonably necessary for Seller to verify the existence of the alleged Title Defect,

and (v) the amount by which Buyer reasonably believes the Allocated Value of each Title Defect Property is reduced by the alleged Title Defect and the computations (with specific supporting detail) upon which Buyer’s belief is based. To give Seller an opportunity to commence reviewing and curing Title Defects, Buyer agrees to provide Seller weekly written notice of all Title Defects discovered by Buyer, which notice may be supplemented on or prior to the Defect Claim Date.

(c) Seller’s Right to Cure. Notwithstanding anything to the contrary herein, Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure, at any time prior to the expiration of ninety (90) days following the Closing (the “Cure Period”), any Title Defects of which it has timely received a Title Defect Notice from Buyer.

(i) If Seller elects to cure a Title Defect pursuant to Section 11(d)(ii) and Seller and Buyer mutually agree that a Title Defect with respect to a Transferred Title Defect Property has been cured, then within five (5) business days after such determination, Seller and Buyer shall execute and deliver all necessary documents to cause the amount withheld in the Defects Escrow (as defined in Section 11(d)(ii)) with respect thereto (and any interest earned thereon) to be released to Seller in accordance with the terms of the Escrow Agreement. If Seller and Buyer mutually agree that a Title Defect with respect to a Transferred Title Defect Property has been partially cured, then Seller and Buyer shall reasonably agree upon the portion of the amount retained in the Defects Escrow with respect thereto (together with any interest earned thereon) that should be paid to Buyer to compensate it for the uncured portion thereof (together with interest earned thereon), and the remaining portion of such amount shall be released to Seller (together with any interest earned thereon) in accordance with the terms of the Escrow Agreement. If as of the 90th day following the Closing, Seller has been unable to cure, or has only partially cured, a Title Defect (and there is no dispute as to whether or not it has been cured or partially cured) with respect to a Transferred Title Defect Property, the amount withheld in the Defects Escrow with respect to the uncured portion thereof shall be released to Buyer, and the amount withheld in the Defects Escrow with respect to the cured portion thereof shall be released to Seller (in both cases, together with any interest earned thereon) and, in both cases, in accordance with the terms of the Escrow Agreement. If by such 90th day following the Closing Seller and Buyer have not agreed whether there has been a satisfactory resolution of a Title Defect with respect to a Transferred Title Defect Property, then such disagreement shall be resolved as provided in Section 5 of Appendix I (provided, the amount owed to Buyer and/or Seller shall be released from the Defects Escrow to the applicable Party (together with any interest earned thereon)). Seller and Buyer agree to jointly instruct the Escrow Agent to pay any applicable amounts in the Defects Escrow in accordance with this Section 11(c)(i).

(ii) With respect to each Title Defect that has been fully cured in accordance with the provisions hereof after the Closing but prior to the expiration of the Cure Period, Seller and Buyer shall, within five (5) business days following Seller’s notice of cure, jointly instruct the Escrow Agent to pay any applicable amounts withheld in the Defects Escrow thereof to Seller.

(iii) If a Title Defect Property is retained by Seller pursuant to Section 11(d)(iii) and Seller thereafter cures, during the Cure Period, the Title Defect for which such exclusion was made, then within five (5) business days after the expiration of the Cure Period, subject to any other provisions of this Agreement, such Title Defect Property (or portion thereof) that was previously excluded shall again be subject to the terms of this Agreement and Buyer shall pay to Seller an amount equal to the Allocated Value of such Title Defect Property (subject to the adjustments set forth in Section 4) and, contemporaneously with Buyer’s payment, Seller shall convey to Buyer such previously excluded Title Defect Property (or portion thereof) pursuant to an assignment instrument substantially in form and substance of Exhibit E.

(d) Remedies for Title Defects. Subject to (w) Seller’s continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto, (x) the Individual Title Defect Threshold, (y) the Aggregate Deductible, and (z) Seller’s ongoing right to cure any Title Defect under Section 11, whether before, at or after Closing, if any Title Defect timely asserted by Buyer in accordance with Section 11(b) is not cured by Closing, then in connection with the Closing, Seller shall, at its sole option and discretion, elect one of the following remedies for such Title Defect:

(i) Convey the entirety of the Title Defect Property that is subject to such Title Defect, in which Seller has elected not to cure, to Buyer, together with all associated Assets, at Closing, and make an accompanying reduction to the Purchase Price in an amount determined pursuant to Appendix I as being the Title Defect Amount;

(ii) Convey the entirety of the Title Defect Property that is subject to such Title Defect, in which Seller has elected to cure, to Buyer, together with all associated Assets, at Closing, and make a reduction to the Purchase Price in an amount determined pursuant to Appendix I as being the Title Defect Amount (or, if the Title Defect Amount is in dispute, Seller’s reasonable, good faith determination thereof) (the “Defects Escrow Amount”). At the Closing, an amount equal to the Defects Escrow Amount shall be retained in the Escrow Account (or if the Defects Escrow Amount exceeds the balance of the Escrow Account, Buyer shall deliver the amount of such excess to the Escrow Agent at the Closing) (the Escrow Account, for such purposes, the “Defects Escrow”). The Defects Escrow Amount with respect to any Title Defect Property will remain therein until released as provided in Section 11(c)(i), and any such Title Defect Property shall be referred to as a “Transferred Title Defect Property”;

(iii) If the Title Defect Amount for such Title Defect equals or exceeds the Allocated Value of such Title Defect Property, subject to Seller’s right to cure in Section 11(c)(iii), retain the entirety of the Title Defect Property that is subject to such Title Defect, together with all associated Assets (in which case, such Assets shall become Excluded Assets hereunder), and reduce the Purchase Price by an amount equal to the Allocated Value of such Title Defect Property (and associated Assets that are so excluded); or

(e) Title Threshold and Deductible. Notwithstanding anything herein to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or any other remedy provided by Seller hereunder or any claim for any breach of the special warranty of Defensible Title contained in the Assignment, for any individual Title Defect for which the Title Defect Amount applicable thereto does not exceed [***] Dollars ($[***]) per Title Defect Property (the “Individual Title Defect Threshold”); and (ii) in no event shall there be any adjustments to the Purchase Price or any other remedy provided by Seller hereunder, including any claim for any breach of the special warranty of Defensible Title, for any Title Defect for which the Title Defect Amount applicable thereto exceeds the Individual Title Defect Threshold unless and until (A) the sum of (1) the Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold, in the aggregate (excluding any Title Defect Amounts attributable to (x) Title Defects cured by Seller, (y) Title Defect Properties retained by Seller pursuant to Section 11(d)(iii), and (z) Title Defects for which Seller will indemnify Buyer pursuant to Section 11(d)(iv)), plus (2) the Remediation Amounts of all Environmental Defects that exceed the Individual Environmental Defect Threshold, in the aggregate (excluding any Remediation Amounts attributable to (x) Environmental Defects cured or Remediated by Seller, (y) Environmental Defect Properties that are retained by Seller pursuant to Section 12(d)(iii), and (z) Environmental Defects for which Seller will indemnify Buyer pursuant to Section 12(d)(iv)), exceeds (B) [***] percent ([***]%) of the unadjusted Purchase Price (the “Aggregate Deductible”), in which case Buyer shall be entitled to remedies for such Title Defects to the extent, but only to the extent, that the aggregate of such amounts are in excess of such Aggregate Deductible.

(F) EXCLUSIVE REMEDY. THE PROVISIONS OF SECTION 11(D) SHALL BE THE EXCLUSIVE RIGHT AND REMEDY OF BUYER WITH RESPECT TO ANY TITLE DEFECT OR OTHER TITLE MATTERS. BUYER HEREBY EXPRESSLY WAIVES ANY AND ALL OTHER RIGHTS OR REMEDIES WITH RESPECT THERETO.

12. Environmental Defects.

(a) Certain Environmental Defect Terms. Appendix II is hereby incorporated by reference.

(b) Assertions of Environmental Defects. On or before the Defect Claim Date, Buyer shall deliver claim notices to Seller meeting the requirements of this Section 12 (collectively, the “Environmental Defect Notices”, and each individually, an “Environmental Defect Notice”) setting forth any matters that constitute Environmental Defects. For all purposes of this Agreement and notwithstanding

anything herein to the contrary, the provisions of Section 12(d) and Section 14(h) shall be the exclusive right and remedy of Buyer with respect to any Environmental Defect or other environmental, health or safety matters and Buyer shall be deemed to have waived, and Seller shall have no liability for, any environmental, health or safety matters, including any Environmental Defect, that Buyer fails to assert as an Environmental Defect in a sufficient Environmental Defect Notice received by Seller on or before the Defect Claim Date. To be effective, each Environmental Defect Notice shall be in writing, and shall include (i) a description of the alleged Environmental Defect (including the applicable Environmental Law(s) violated thereby), (ii) identification of the Asset(s) affected by the alleged Environmental Defect (each such Asset, as applicable, an “Environmental Defect Property”), (iii) the Allocated Value of each Environmental Defect Property, (iv) supporting documents available to Buyer reasonably necessary for Seller to verify the existence of the alleged Environmental Defect, and (v) a calculation (with reasonable supporting detail) of the Remediation Amount that Buyer asserts is attributable to the alleged Environmental Defect. To give Seller an opportunity to commence reviewing and curing Environmental Defects, Buyer agrees to provide Seller weekly written notice of all Environmental Defects discovered by Buyer during the preceding period after the date the Agreement is signed and prior to delivery of such notice, which notice may be supplemented on or prior to the Defect Claim Date. Buyer’s calculation of the Remediation Amount included in the Environmental Defect Notice must describe in reasonable detail the Remediation proposed for the Environmental Condition that gives rise to the asserted Environmental Defect and identify all assumptions used by Buyer in calculating the Remediation Amount, including the standards that Buyer asserts must be met to comply with Environmental Laws.

(c) Seller’s Right to Cure. Notwithstanding anything to the contrary herein, Seller shall have the right, but not the obligation, to attempt, at its sole cost, to Remediate, at any time prior to the end of the Cure Period, any Environmental Defect of which it has timely received an Environmental Defect Notice from Buyer. In the event that an Environmental Defect Property is retained by Seller pursuant to Section 12(d)(iii) and Seller thereafter Remediates, during the Cure Period, the Environmental Defect for which such exclusion was made, then within five (5) business days after the expiration of the Cure Period, subject to any other provisions of this Agreement that would require the exclusion of such Asset, such Environmental Defect Property (or portion thereof) that was previously excluded shall again be subject to the terms of this Agreement and Buyer shall pay to Seller an amount equal to the Allocated Value of such Environmental Defect Property (subject to the adjustments set forth in Section 4), and, contemporaneously with Buyer’s payment, Seller shall convey to Buyer such previously excluded Environmental Defect Property (or portion thereof) pursuant to an assignment instrument in form and substance of Exhibit E.

(d) Remedies for Environmental Defects. Subject to (w) Seller’s continuing right to dispute the existence of an Environmental Defect and/or the Remediation Amount asserted with respect thereto, (x) the Individual Environmental Defect Threshold, (y) the Aggregate Deductible, and (z) Seller’s ongoing right to Remediate any Environmental Defect under Section 12(c), if any Environmental Defect timely asserted by Buyer in accordance with Section 12(b) is Remediated, then in

connection with the Closing Seller shall, at its sole option and discretion, elect one or more of the following remedies for such Environmental Defect:

(i) Seller will convey the entirety of the Environmental Defect Property that is subject to such Environmental Defect, in which Seller has not elected to cure, to Buyer, together with all associated Assets, at Closing, and make an accompanying reduction to the Purchase Price by the Remediation Amount for such Environmental Defect agreed to by the Parties or otherwise determined pursuant to Appendix II;

(ii) Intentionally omitted;

(iii) If the Remediation Amount for such Environmental Defect equals or exceeds the Allocated Value of such Environmental Defect Property, retain the entirety of the Environmental Defect Property that is subject to such Environmental Defect, together with all associated Assets (in which case, such Assets shall become Excluded Assets hereunder), and reduce the Purchase Price by an amount equal to the Allocated Value of such Environmental Defect Property and such associated Assets; or

(iv) Seller will convey the entirety of the Environmental Defect Property that is subject to such Environmental Defect to Buyer, and indemnify Buyer for six (6) months after the Closing date against all liability, up to the lesser of the Allocated Value or the Remediation Amount of the affected Environmental Defect Property, resulting from such Environmental Defect pursuant to an indemnity agreement prepared by the Parties in a form and substance reasonably acceptable to the Parties provided, that Seller may not elect this remedy without Buyer’s written consent, which may be withheld in Buyer’s sole discretion.

If the option set forth in clause (i) above is selected, subject to Seller’s right to Remediate any Environmental Defect under Section 12(c), (x) Buyer shall be deemed to have assumed responsibility for all costs and expenses attributable to the Remediation of the applicable Environmental Defect and all liabilities with respect thereto, and (y) Buyer’s obligations with respect to the foregoing shall be deemed to constitute Assumed Obligations. If Seller elects to attempt to Remediate any Environmental Defect pursuant to Section 12(c), Seller shall use reasonable efforts to implement such Remediation in a manner which is consistent with the requirements of Environmental Laws for the type of Remediation that Seller elects to undertake and Buyer, effective as of the Closing, to the extent necessary, hereby grants to Seller and its representatives access to (x) the Assets to conduct such Remediation and (y) any utilities located on the Assets in order to undertake such Remediation.

(e) EXCLUSIVE REMEDY. THE PROVISIONS OF SECTION 12(D) AND SECTION 14(H) SHALL BE THE EXCLUSIVE RIGHT AND REMEDY OF BUYER WITH RESPECT TO ANY ENVIRONMENTAL DEFECT OR OTHER ENVIRONMENTAL, HEALTH OR SAFETY MATTERS. BUYER HEREBY EXPRESSLY WAIVES ANY AND ALL OTHER RIGHTS OR REMEDIES WITH RESPECT THERETO.

(f) Environmental Threshold and Deductible. Notwithstanding anything herein to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or any other remedy provided by Seller hereunder for any individual Environmental Defect for which the Remediation Amount applicable thereto does not exceed [***] Dollars ($[***]) (the “Individual Environmental Defect Threshold”) and (ii) in no event shall there be any adjustments to the Purchase Price or any other remedy provided by Seller hereunder for any Environmental Defect for which the Remediation Amount applicable thereto exceeds the Individual Environmental Defect Threshold unless and until (A) the sum of (1) the Remediation Amounts of all such Environmental Defects that exceed the Individual Environmental Defect Threshold, in the aggregate (excluding any Remediation Amounts attributable to (x) Environmental Defects Remediated by Seller, (y) Environmental Defect Properties that are retained by Seller pursuant to Section 12(d)(iii), and (z) Environmental Defects for which Seller will indemnify Buyer pursuant to Section 12(d)(iv)), plus (2) the Title Defect Amounts of all Title Defects that exceed the Individual Title Defect Threshold, in the aggregate (excluding any Title Defect Amounts attributable to (x) Title Defects cured by Seller, (y) Title Defect Properties retained by Seller pursuant to Section 11(d)(iii), and (z) Title Defects for which Seller will indemnify Buyer pursuant to Section 11(d)(iv)), exceeds (B) the Aggregate Deductible, in which case Buyer shall be entitled to remedies for such Environmental Defects only to the extent that the aggregate of such amounts are in excess of such Aggregate Deductible.

13. NORM, Wastes and Other Substances. Buyer acknowledges that the Assets have been used for exploration, development and production of oil and gas and that there may be petroleum, produced water, wastes or other substances or materials located in, on or under the Assets or associated with the Assets. Equipment and sites included in the Assets may contain asbestos, naturally occurring radioactive material (“NORM”) or other hazardous materials. NORM may affix or attach itself to the inside of wells, materials and equipment as scale, or in other forms. The Wells, materials and equipment located on the Lands or included in the Assets may contain NORM and other wastes or hazardous materials. NORM containing material and/or other wastes or hazardous materials may have come in contact with various environmental media, including water, soils or sediment. Special procedures may be required for the assessment, remediation, removal, transportation or disposal of environmental media, wastes, asbestos, NORM and other hazardous materials from the Assets. Notwithstanding anything herein to the contrary, Buyer shall not be permitted to claim any Environmental Defect on the account of the presence of NORM on the Assets or the properties underlying the Assets.

19. Taxes.

(a) All required documentary, filing and recording fees and expenses in connection with the filing and recording of the assignments (including the Assignment), conveyances or other instruments required to convey title to the Assets to Buyer shall be borne by Buyer. Buyer shall be responsible for, and shall bear and pay, all sales, use, transfer, stamp, registration and similar Taxes (including any applicable interest or penalties) incurred or imposed with respect to the transactions described in this Agreement (the “Transfer Taxes”). Seller shall bear and pay, all ad valorem, property, excise, severance, production, sales, use and similar Taxes (including any interest, fine, penalty or additions to Tax imposed by a government authority in connection with such Taxes) based upon ownership of the Assets or production of hydrocarbons or the receipt of proceeds therefrom (for the avoidance of doubt, excluding any Transfer Taxes) (collectively, the “Asset Taxes”) assessed with respect to the ownership of the Assets for (i) any period ending prior to the Effective Time, and (ii) with respect to any Tax period beginning before and ending after the Effective Time (a “Straddle Period”), the portion of such Straddle Period ending immediately prior to the date on which the Effective Time occurs. All Asset Taxes arising on or after the Effective Time (including all Asset Taxes for the portion of any Straddle Period beginning on the date on which the Effective Time occurs) shall be allocated to and borne by Buyer. To the extent the actual amount of any Asset Taxes described in this Section 19 is not known at the time an adjustment is to be made with respect to such Asset Tax pursuant to Section 4, as applicable, Buyer and Seller shall utilize the most recent information available in estimating the amount of such Asset Taxes for purposes of such adjustment. Upon determination of the actual amount of Asset Taxes,

payments will be made to the extent necessary to cause the appropriate Party to bear the Asset Taxes allocable to such Party under this Section 19 (without duplication of any amounts that were reflected as an adjustment to the Purchase Price). For purposes of allocation between the Parties of Asset Taxes: (A) Asset Taxes that are attributable to the severance or production of hydrocarbons or otherwise imposed on a transactional basis (other than Asset Taxes described in clause (B) below) shall be allocated to the period in which the severance, production or other transaction giving rise to such Asset Taxes occurred; and (B) Asset Taxes that are ad valorem, property or other Asset Taxes imposed on a periodic basis with respect to a Straddle Period shall be allocated pro rata per day between the portion of such Straddle Period ending immediately prior to the date on which the Effective Time occurs (which shall be Seller’s responsibility) and the portion of such Straddle Period beginning on the date on which the Effective Time occurs (which shall be Buyer’s responsibility). For purposes of clause (A) of the preceding sentence, any exemption, deduction, credit or other item that is calculated on an annual basis shall be allocated pro rata per day between the period ending immediately prior to the date on which the Effective Time occurs and the period beginning on the date on which the Effective Time occurs.

(b) Other than with respect to Tax periods ending prior to the Effective Time (which shall be prepared by Seller), Buyer shall be responsible for filing with the appropriate governmental authorities all Tax Returns, in each case, for Asset Taxes that are required to be filed after the Closing and paying the Asset Taxes reflected on such Tax Returns, subject to Buyer’s right of reimbursement for any Asset Taxes for which Seller is responsible under Section 19(a), except to the extent such Asset Taxes were reflected as an adjustment to the Purchase Price. Buyer shall prepare all such Tax Returns relating to any Straddle Period on a basis consistent with past practice except to the extent otherwise required by applicable law. Buyer shall provide Seller with a copy of any such Tax Return for Seller’s review at least ten (10) days prior to the due date for the filing of such Tax Return (or within a commercially reasonable period after the end of the relevant taxable period, if such Tax Return is required to be filed less than ten (10) days after the close of such taxable period), and Buyer shall incorporate all reasonable comments of Seller provided to Buyer in advance of the due date for the filing of such Tax Return. Buyer shall indemnify and hold Seller harmless for any failure to file such Tax Returns and to make such payments.

(c) Each Party shall cooperate fully, as and to the extent reasonably requested by any other Party, in connection with the filing of any Tax Returns, state and federal regulatory reports, royalty payments including related deduction and any audit, litigation or other proceeding with respect to Taxes.

(d) Seller shall be entitled to any and all refunds of Asset Taxes allocated to Seller pursuant to Section 19(a), and Buyer shall be entitled to any and all refunds of Asset Taxes allocated to Buyer pursuant to Section 19(a). If a Party receives a refund of Asset Taxes to which the other Party is entitled pursuant to this Section 19(d), the first Party shall promptly pay such amount to the other Party, net of any reasonable costs or expenses incurred by the first Party in procuring such refund.

(e) Seller shall deliver to Buyer a schedule with an allocation of the Purchase Price (and any liabilities assumed by Buyer under this Agreement or other amounts that

are treated as consideration for United States federal income Tax purposes) among the Assets in accordance with Section 1060 of the Code (the “Tax Allocation”) within ninety (90) days after the Closing date. Seller and Buyer each agree to prepare, and to cause their respective affiliates to prepare all Tax Returns, including Form 8594 (Asset Acquisition Statement under Section 1060 of the Code), in a manner consistent with the Tax Allocation, as revised to take into account subsequent revisions by Seller as a result of adjustments to the Purchase Price, and the Parties shall not take any position inconsistent therewith on any Tax Return or in connection with any Tax audit, claim or similar proceeding unless required to do so by any applicable law after notice to and discussions with the other Party, or with such other Party’s prior consent; provided, however, that 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 Tax Allocation.

20. Termination.

(a) Subject to Section 20(b), this Agreement may be terminated at any time prior to the consummation of the Closing upon the occurrence of any one or more of the following:

(i) by mutual written agreement of Seller and Buyer;

(ii) by Seller or Buyer if the other Party has materially breached this Agreement and such breach causes any of the conditions to close of the non-breaching Party set forth in Sections 16 and 17, respectively, not to be satisfied as of Closing; provided, however, that in the case of a breach that is capable of being cured, the breaching Party shall have until the earlier of (A) ten (10) days following notice of breach to attempt to cure the breach and (B) one (1) business day prior to the Outside Date;

(iii) by Seller or Buyer, pursuant to the last paragraph of Section 16 or 17, respectively or Section 21(l); or

(iv) by Seller or Buyer if the closing shall not have occurred on or before September 12, 2019 (the “Outside Date”);

provided, however, that neither Party shall have the right to terminate this Agreement pursuant to clause (ii) or (iv) if such Party is at such time in material breach of any provision of this Agreement.

(b) Remedies.

(i) If Seller has the right to terminate this Agreement pursuant to (A) Section 20(a)(ii) or (B) Section 20(a)(iv) in a situation where the conditions to closing set forth in Section 17 have been satisfied or waived in writing by Buyer (excluding conditions that by their terms, cannot be satisfied until the Closing), and Seller has performed or is ready, willing and able to perform all of its agreements and covenants contained herein which are to be performed or observed at or prior to the Closing, then Seller shall, as its sole and exclusive remedy, be entitled to (x) terminate this Agreement

and cause the Parties to promptly instruct the Escrow Agent to pay the Deposit (plus any interest earned thereon) to Seller as liquidated damages, or (y) in lieu of terminating this Agreement, seek specific performance. THE PARTIES RECOGNIZE THAT ACTUAL DAMAGES FOR BUYER’S BREACH WOULD BE DIFFICULT TO ASCERTAIN WITH REASONABLE CERTAINTY AND THAT THE DEPOSIT WOULD BE REASONABLE LIQUIDATED DAMAGES FOR SUCH BREACH.

(ii) If Buyer has the right to terminate this Agreement pursuant to (A) Section 20(a)(ii) or (B) Section 20(a)(iv) in a situation where the conditions to Closing set forth in Section 16 have been satisfied or waived in writing by Seller (excluding conditions that by their terms, cannot be satisfied until the Closing), and Buyer has performed or is ready, willing and able to perform all of its agreements and covenants contained herein which are to be performed or observed at or prior to the Closing, then Buyer shall, as its sole and exclusive remedy, be entitled to (x) terminate this Agreement and cause the Parties to promptly instruct the Escrow Agent to pay the Deposit (plus any interest earned thereon) to Buyer, or (y) in lieu of terminating this Agreement, seek specific performance, it being specifically agreed that monetary damages will not be sufficient to compensate the Buyer.

(iii) If this Agreement terminates for reasons other than those set forth in Section 20(b)(i) or Section 20(b)(ii), then (A) the Parties shall have no liability or obligation hereunder as a result of such termination, (B) the Parties shall promptly instruct the Escrow Agent to pay the Deposit (plus any interest earned thereon) to Buyer, and (C) Seller shall be free immediately to enjoy 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. If Buyer first seeks specific performance under clause (ii), as applicable, but is unable to recover therefor from a court of competent jurisdiction, Buyer may thereafter elect to terminate this Agreement and cause the Parties to promptly instruct the Escrow Agent to pay the Deposit (plus any interest earned thereon) to Buyer. The following provisions shall survive termination: Sections 9, 20(b), 21(d), 21(h) and 21(j).

21. Miscellaneous. The Parties further agree as follows:

(a) Assignment. Neither Party shall assign its rights or obligations under this Agreement without the prior written consent of the other Party, which consent may be withheld for any reason in the sole discretion of the non-assigning Party.

(b) Governing Law; Venue; Jury Waiver. This Agreement shall be governed and construed in accordance with the laws of the State of Texas, excluding any conflicts of law principles; provided, however, that any matters related to real property shall be governed by the laws of the state in which the applicable real property is located. Each of the Parties consent to the exercise of jurisdiction in personam by the United States Federal District Courts or State Courts located in Houston, Harris County, Texas. EACH PARTY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE

TO A TRIAL BY JURY IN RESPECT OF ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE ASSIGNMENT OR ANY TRANSACTION CONTEMPLATED HEREBY OR THEREBY.

(d) Confidentiality. The Parties shall keep this Agreement and their negotiations with respect to the Assets strictly confidential and, without the prior written consent of the other Party, shall not disclose the same to any third person or Party other than to their respective affiliates and such Party’s and its affiliates’ respective officers, directors, managers, members, employees, agents, advisors, attorneys, consultants and representatives. The Parties shall be entitled to disclose the terms of this Agreement with marketing companies with which the Parties have prior dedications covering the Lands and any holders of preferential rights to purchase or consents to assign rights that are triggered by this transaction.

(e) Counterparts; Treatment as Original. This Agreement may be executed in one (1) or more counterparts, each of which will be deemed an original and all of which together shall constitute the same agreement, and any signature hereto delivered by a Party by facsimile or other electronic transmission (e.g., email) shall be deemed an original signature hereto for all purposes.

(f) Knowledge. Intentionally Omitted.

(g) Press Release. If any Party wishes to make a press release or other public announcement respecting this Agreement or the transactions hereby, such Party will provide the other Party with a draft of the press release or other public announcement for review at least one (1) business day prior to the time that such press release or other public announcement is to be made. The Parties will attempt in good faith to expeditiously reach agreement on such press release or other public announcement and the contents thereof. Failure to agree or to provide comments back to the other Party within one (1) business day of receipt of the draft release or announcement will be deemed consent to the public disclosure of such press release or other public announcement and the content thereof, so long as the reviewing Party’s name is not included in the release or announcement. Seller and Buyer shall each be liable for the compliance of their respective affiliates with the terms of this Section 21(g). No Party shall issue a press release or other public announcement that includes the name of a non-releasing Party or its affiliates without the prior written consent of such non-releasing Party (which consent may be withheld in such non-releasing Party’s sole discretion). Notwithstanding anything in this Section 21(g) to the contrary, nothing in this Section 21(g) shall prohibit any Party from issuing or making a public announcement or statement if such Party deems it necessary to do so in order to comply with any applicable law, or the rules of any stock exchange upon which such Party’s or such Party’s affiliate’s capital stock is traded; provided, however, to the extent reasonably practicable, prior written notification shall be given to the other Party prior to any such announcement or statement.

(h) Notices. All communications required or permitted under this Agreement shall be in writing and any communication or delivery hereunder shall be deemed to have been fully made if actually delivered, if mailed by registered or certified mail, postage prepaid, delivered by recognized overnight courier service, to the address as set forth below:

(i) Disclosures with Multiple Applicability; Materiality. If any fact, condition, or matter disclosed by Seller on an Exhibit and/or Schedule applies to more than one (1) provision of this Agreement, a single disclosure of such fact, condition or matter on Seller’s Exhibits and/or Schedules shall constitute disclosure with respect to all provisions of this Agreement to which such fact, condition, or other matter applies, regardless of the provision of Seller’s Exhibits and/or Schedules in which such fact, condition or other matter is described to the extent that the applicability of such matter so referenced is reasonably apparent on the face of such included matter.

(j) Limitation on Damages. NOTWITHSTANDING ANYTHING CONTAINED IN THIS AGREEMENT TO THE CONTRARY, EXCEPT IN CONNECTION WITH ANY DAMAGES INCURRED BY THIRD PARTIES FOR WHICH INDEMNIFICATION IS SOUGHT UNDER THE TERMS OF THIS AGREEMENT, NO MEMBER OF BUYER GROUP OR SELLER GROUP SHALL BE ENTITLED TO (AND EACH SUCH MEMBER WAIVES) CONSEQUENTIAL, SPECIAL, INDIRECT, PUNITIVE OR EXEMPLARY DAMAGES, OR DAMAGES FOR LOST PROFITS OF ANY KIND, IN CONNECTION WITH EITHER THIS AGREEMENT, THE ASSIGNMENT

DELIVERED AT CLOSING OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

(k) Time. Time is of the essence in this Agreement. Without limiting the generality of the foregoing, this Agreement contains a number of dates and times by which performance or the exercise of rights is due, and the Parties intend that each and every such date and time be the firm and final date and time, as agreed herein.

(l) Casualty Loss. Notwithstanding anything herein to the contrary, from and after the execution of this Agreement, if Closing occurs, Buyer shall assume all risk of loss with respect to the depreciation of Assets due to ordinary wear and tear. If, after the execution of the Agreement but prior to or on the Closing date, any portion of the Assets are destroyed by fire, explosion, 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 by any governmental entity, whether or not fixed or repaired or in any way remediated (each a “Casualty Loss”), Buyer and Seller shall nevertheless be required to proceed with Closing. Notwithstanding such Casualty Loss, in the event of any such Casualty Loss, at the Closing, Seller shall pay to Buyer all sums paid to Seller by third parties by reason of the destruction or taking of such Assets, including any sums paid pursuant to any policy or agreement of insurance or indemnity, and shall assign, transfer and set over unto Buyer all of the rights, titles and interests of Seller in and to any claims, causes of action, unpaid proceeds or other payments from third parties, including any policy or agreement of insurance or indemnity, arising out of such destruction or taking. Notwithstanding anything to the contrary contained in this paragraph, if prior to the Closing, Assets having an aggregate Allocated Value constituting more than [***] percent ([***]%) of the Purchase Price are damaged or destroyed by fire or other casualty, or taken in condemnation or under the right of eminent domain, or proceedings for such purpose are pending or threatened, Buyer shall have the right to terminate this Agreement.

(m) References and Rules of Construction. All references in this Agreement to Exhibits, Schedules, Articles, Sections, subsections and other subdivisions refer to the corresponding Exhibits, Schedules, Articles, Sections, subsections and other subdivisions of or to this Agreement unless expressly provided otherwise. Titles appearing at the beginning of any Articles, Sections, subsections and other subdivisions of this Agreement are for convenience only, do not constitute any part of this Agreement, and shall be disregarded in construing the language hereof. The words “this Agreement,” “herein,” “hereby” and “hereunder,” and words of similar import, refer to this Agreement as a whole and not to any particular Article, Section, subsection or other subdivision unless expressly so limited. The words “this Article,” “this Section” and “this subsection,” and words of similar import, refer only to the Article, Section or subsection hereof in which such words occur. Wherever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limiting the foregoing in any respect.” All references to “$” or “Dollars” shall be deemed references to United States Dollars. Pronouns in masculine, feminine or neuter genders shall be construed to state and include any other gender, and words, terms and titles (including terms defined herein) in the singular form shall be construed to include the plural and vice versa, unless the context otherwise requires. The

words “shall” and “will” are used interchangeably throughout this Agreement and shall accordingly be given the same meaning, regardless of which word is used.

(n) No Recourse. This Agreement may only be enforced against, and any claims or causes of action that may be based upon, arise out of or relate to this Agreement, may only be made against the entities that are expressly identified as Parties hereto in their capacities as such and no other party shall have any liability for any obligations or liabilities of the Parties to this Agreement or for any claim (whether in tort, contract or otherwise) based on, in respect of, or by reason of, the transactions contemplated hereby or in respect of any representations made or alleged to be made in connection herewith. Without limiting the rights of any Party against the other Parties hereto, in no event shall any Party or any of its affiliates seek to enforce this Agreement against, make any claims for breach of this Agreement against, or seek to recover monetary damages from, any non-Party to this Agreement.

(o) Operation of Business. Until Closing, Seller (a) will operate its business in the ordinary course consistent with past practices as a reasonably prudent operator, and (b) will not, without the prior written consent of Buyer, which consent shall not be unreasonably withheld, conditioned or delayed:

(i) expend any funds, or make any commitments to expend funds (including entering into new agreements which would obligate Seller or Buyer to expend funds), or otherwise incur any other obligations or liabilities, in connection with the ownership of the Assets after the Effective Time, other than routine expenses incurred in the normal operation of the existing wells on the Lands, except in the event of an emergency requiring immediate action to protect life or preserve the Assets;

(ii) except where necessary to prevent termination of an oil and gas lease or other material agreement covering Seller’s interest in the Assets:

(1) propose to or agree to the drilling of additional wells, or propose the deepening, of any existing wells;

(2) propose or agree to the conducting of any other operations which require consent under the applicable operating agreement;

(3) propose or agree to the conducting of any other operations other than the normal operation of the existing wells on the Lands; or

(4) propose to or agree to the abandonment of any wells on the Lands;

Seller agrees that it will advise Buyer of any such proposals made by third parties and will not agree to any such proposal made by a third party unless the prior written consent of Buyer is obtained (which consent shall not be unreasonably withheld, delayed or conditioned);

(iii) commit to any operation, or series of related operations, reasonably anticipated by Seller to require future capital expenditures by the owner of the Assets in excess of Two Hundred Fifty Thousand Dollars

($250,000.00), net to Seller’s working interest, or make any capital expenditures in excess of Two Hundred Fifty Thousand Dollars ($250,000.00), net to Seller’s working interest, or voluntarily terminate, materially amend or extend any material Contract;

(iv) fail to maintain insurance coverage on the Assets presently furnished by nonaffiliated third parties in the amounts and of the types presently in force;

(v) fail to use commercially reasonable efforts to maintain in full force and effect all Leases;

(vi) fail to maintain all material governmental authorizations;

(vii) transfer, farmout, sell, hypothecate, encumber or otherwise dispose of any material Assets or material rights related thereto, except for sales and dispositions of hydrocarbon production and obsolete or worn out equipment made in the ordinary course of business consistent with past practices;

(viii) commit to do any of the foregoing;

(ix) without Buyer’s written consent, make any non-consent elections with respect to operations affecting any of the Assets; and

(x) fail to promptly give Buyer notice of any written notice claiming any default or violation received or given by Seller under any Lease, contract or law affecting any Asset that would reasonably be expected to be material to the Assets, taken as a whole.

Buyer’s approval of any action restricted by this Section 21(o) shall be considered granted within ten (10) days (unless a shorter time is reasonably required by the circumstances and such shorter time is specified in Seller’s written notice) of Seller’s notice to Buyer requesting such consent unless Buyer notifies Seller to the contrary in writing during that period. In the event of an emergency, Seller may take such action as a prudent non-operator would take and shall notify Buyer of such action promptly thereafter. Buyer acknowledges that Seller may own an undivided interest in certain Assets and Buyer agrees that the acts or omissions of the other working interest owners who are not affiliated with Seller shall not constitute a violation of the provisions of this Section 21(o) nor shall any action required by a vote of working interest owners constitute such a violation so long as Seller has voted its interest in a manner consistent with the provisions of this Section 21(o).

(p) Preferential Purchase Rights. Seller shall, prior to the Closing date, provide all notices necessary to comply with or obtain the waiver of all preferential rights to purchase which are triggered by this transaction prior to the Closing date and in compliance with the contractual provisions applicable thereto. To the extent any such preferential rights to purchase are exercised by any holders thereof, then the Asset(s) subject to such preferential rights to purchase shall not be sold to Buyer and shall be excluded from the Assets and sale under this Agreement and shall be

considered Excluded Assets. The Purchase Price shall be adjusted downward by the Allocated Value of the Asset(s) so retained. On the Closing date, if the time period for exercising any preferential rights to purchase has not expired, but no notice of waiver (nor of the exercise of such preferential rights to purchase) has been received from the holder thereof, then the Asset(s) subject to such preferential rights to purchase shall be included in the Assets sold to Buyer at the Closing, with no adjustment to the Purchase Price. After the Closing, if the holder of such preferential rights to purchase exercises the preferential rights to purchase, then Buyer shall convey the affected Asset(s) to such party, and shall receive the consideration for such affected Asset(s) directly from such party. If any holder of a preferential right to purchase initially elects to exercise that preferential right to purchase, but after the Closing date, refuses to consummate the purchase of the affected Asset(s), then, subject to the Parties’ respective rights and remedies as to the obligation to consummate the transactions contemplated by this Agreement, Buyer shall purchase such Asset(s) for the Allocated Value thereof (subject to the adjustments pursuant to Section 4), and the closing of such transaction shall take place on a date reasonably designated by Seller not more than one hundred eighty (180) days after the Closing date. If such holder’s refusal to consummate the purchase of the affected Asset(s) occurs prior to the Closing date, then, subject to the Parties’ respective rights and remedies as to the obligation to consummate the transactions contemplated hereby, Buyer shall purchase the affected Asset(s) at the Closing in accordance with the terms of this Agreement.

(q) Consents. Seller shall, prior to the Closing date, provide all notices required to comply with or obtain all consents in compliance with the contractual provisions applicable thereto required for the transfer of the Assets.

(i) If Seller fails to obtain any consent necessary for the transfer of any Asset to Buyer, Seller’s failure shall be handled as follows:

(1) If the consent is not a consent with respect to which (a) there is a provision within the applicable instrument that such consent may be withheld in the sole and absolute discretion of the holder, or (b) there is provision within the applicable instrument expressly stating that an assignment in violation thereof (i) is void or voidable, (ii) triggers the payment of specified liquidated damages, or (iii) causes termination of the applicable Assets to be assigned (any consent in the foregoing clauses (a) or (b), a “Required Consent”); provided that, for the avoidance of doubt, “Required Consent” does not include any consent, which, by its terms, cannot be unreasonably withheld, (unless clause (b) of the preceding sentence applies), and has not been denied in writing, then the affected Assets shall nevertheless be conveyed at the Closing as part of the Assets. Any Damages that arise due to the failure to obtain such consent shall be borne by Buyer.

(2) If the consent is a Required Consent or a consent that has been denied in writing, the Purchase Price shall be adjusted downward by the Allocated Value of the affected Assets (which affected Assets shall include all Leases and Wells affected by the Contract or Lease for which a consent is refused or unobtained), and the affected Assets shall be treated as Excluded Assets.

(ii) Notwithstanding the provisions of Section 21(q)(i), if Seller obtains a consent described in Section 21(q)(i) within one hundred eighty (180) days

after the Closing, then Seller shall promptly deliver conveyances of the affected Asset(s) to Buyer and Buyer shall pay to Seller an amount equal to the Allocated Value of the affected Asset(s) in accordance with wire transfer instructions provided by Seller (subject to the adjustments set forth in Section 4).

(r) Tag-Along Rights. Buyer acknowledges and agrees that certain of the Assets may be subject to certain tag-along rights in favor of EnerVest Energy Institutional Co-Investment XII-1A, L.P., a Delaware limited partnership (“EnerVest Fund 1A”) and EnerVest Energy Institutional Fund XII-WIB, L.P., a Delaware limited partnership (“EnerVest Fund B”, and together with EnerVest Fund 1A, each an “EnerVest Entity” and collectively, “EnerVest”), which apply to the transactions contemplated hereunder as provided in that certain letter agreement by and among Seller and EnerVest, dated April 9, 2019 (the “EnerVest Letter Agreement”). Therefore, within five (5) business days after the date this Agreement is signed, Seller shall notify EnerVest in writing of the transactions contemplated by this Agreement in a “Tag-Along Notice” in compliance with the EnerVest Letter Agreement, and each EnerVest Entity shall have ten (10) business days after its receipt of such notice to elect whether to exercise such tag-along right to sell its interest in the properties conveyed pursuant to this Agreement (the “Tag-Along Right Properties”). In accordance with the EnerVest Letter Agreement, the Tag-Along Notice shall state that the amount and type of consideration that would be allocated to purchase the Tag-Along Right Properties, as provided below.

In the event one or both EnerVest Entities elects to exercise its tag-along right to sell its interest in the Tag-Along Right Properties, each such EnerVest Entity will enter into a separate agreement with Buyer in substantially the same form of this Agreement and will sell all, but not less than all, of its interest in the Tag-Along Right Properties to Buyer on substantially the same terms and conditions as set forth in this Agreement, subject to the adjustments described below.

In the event any EnerVest Entity does not timely elect to exercise such tag-along right to sell and does not timely enter into a separate agreement with Buyer in substantially the same form of this Agreement, the tag-along right in favor of such EnerVest Entity shall no longer apply to the transactions contemplated hereunder.

The amount and type of consideration that would be allocated to purchase the interest of each EnerVest Entity shall be determined by (i) adjusting the Allocated Values in such separate agreements so as to be proportionately reduced based on the NRI and working interests (taking into account all associated burdens) represented by such EnerVest Entity in the Tag-Along Right Properties, relative to the relevant NRI and working interests (taking into account all associated burdens) represented by Seller (taking into account the Allocated Values under this Agreement) and (ii) calculating the total Purchase Price in such separate agreements as the sum of such adjusted Allocated Values. The Deposit, the Individual Title Defect Threshold, and the Individual Environmental Defect Threshold shall also be proportionately reduced on the same basis in such separate agreement(s).

(s) Future Cooperation. Buyer and Seller shall execute and deliver, or shall cause to be executed and delivered from time to time, such further instruments of

IN WITNESS WHEREOF, the Parties have executed and delivered this Agreement as of July 29, 2019.

4. Title Defects; Title Defect Amounts.

(a) A “Title Defect” shall mean any encumbrance that causes Seller not to have Defensible Title in and to any Asset; provided that Permitted Encumbrances shall not be considered Title Defects.

(i) If the Title Defect is a deficiency in NRI, the Title Defect Amount shall be equal to the product of (A) the Allocated Value of the affected Asset, multiplied by, (B) a fraction, (1) the numerator of which is the difference between Seller’s actual NRI and the NRI set forth on Exhibit B for the

Title Defect Property, and (2) the denominator of which is the NRI set forth on Exhibit B for such Title Defect Property;

(ii) If the Title Defect is a lien, encumbrance or other charge which is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the affected Asset; and

(iii) If the Title Defect is not of the type described in subsection 4(b)(i) or 4(b)(ii) above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the reasonably anticipated cost to cure the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property and such other reasonable factors as are necessary to make a proper evaluation. The Title Defect Amount with respect to a Title Defect Property shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder.

(iv) Notwithstanding anything to the contrary in this Appendix I Section 4, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property (whether related to an adjustment to the Purchase Price or any other remedy provided by Seller hereunder or any claim for any breach of the special warranty of Defensible Title contained in the Assignment) shall not exceed (A) the reasonable cost and expense of curing such Title Defect (if such Title Defect is reasonably capable of being cured) or (B) the Allocated Value of such Title Defect Property.

5. Independent Expert.

(a) Any disputes regarding Title Defects, Environmental Defects, Title Defect Amount, Remediation Amount, appropriate cure of any Title Defect or Remediation of any Environmental Defect, or the Final Settlement Statement or other accounting matters that are not resolved within one hundred fifty (150) days following Closing may be submitted by a Party, with written notice to the other Party, to an independent expert (the “Independent Expert”), who shall serve as the sole and exclusive arbitrator of any such dispute. The Independent Expert shall be selected by Buyer and Seller (acting reasonably and in good faith) within fifteen (15) days following the effective date of said notice. The Independent Expert must (a) be a neutral party who has never been an officer, director or employee of or performed material work for a Party or any Party’s affiliate within the preceding five (5)-year period and (b) agree in writing to keep strictly confidential the specifics and existence of the dispute as well as all proprietary records of the Parties reviewed by the Independent Expert in the process of resolving such dispute. For any title matter, the Independent Expert must have not less than ten (10) years’ experience as a lawyer with experience in oil and gas titles involving properties in the same geographic region in which the Assets are located. For any environmental matter, the Independent Expert must have not less than ten (10) years’ experience in environmental matters involving oil and gas properties in the same geographic region in which the Assets are located. If disputes exist with

respect to both title and environmental matters, the Parties will conduct separate arbitration proceedings with the title disputes and environmental disputes being submitted to separate Independent Experts. For any Final Settlement Statement or accounting matter, the Independent Expert shall be the Houston, Texas office of the American Arbitration Association.

(b) If Buyer and Seller fail to select an Independent Expert within the fifteen (15) day period referred to in Appendix I Section 5(a) above, within three (3) days thereafter, each of Buyer and Seller shall choose an Independent Expert meeting the qualifications set forth above, and such experts shall promptly choose a third Independent Expert (meeting the qualifications provided for herein) who alone shall resolve the disputes between Buyer and Seller. Buyer and Seller shall each bear its own costs and expenses incurred in connection with any such proceeding and one-half (1/2) of the costs and expenses of the Independent Expert.

(c) Disputes to be resolved by an Independent Expert shall be resolved in accordance with the Commercial Arbitration Rules of the AAA as supplemented to the extent necessary to determine any procedural appeal questions by the Federal Arbitration Act (Title 9 of the United States Code), but only to the extent such rules do not conflict with the terms of Appendix I and Appendix II, mutually agreed procedures and rules and, failing such agreement, in accordance with the rules and procedures for non-administered arbitration set forth in the commercial arbitration rules of the American Arbitration Association. The decision and award of the Independent Expert shall be binding upon the Parties and final and non-appealable to the maximum extent permitted by law and judgment thereon may be entered in a court of competent jurisdiction and enforced by any Party as a final judgment of such court.

(d) Within five (5) business days following the receipt by either Party of written notice of a dispute, the Parties will exchange their written description of the proposed resolution of the disputed matters. Provided that no resolution has been reached, within five (5) business days following the selection of the Independent Expert, the Parties shall submit to the Independent Expert the following: (i) this Agreement, (ii) Buyer’s written description of the proposed resolution of the disputed matters, together with any relevant supporting materials, (iii) Seller’s written description of the proposed resolution of the disputed matters, together with any relevant supporting materials, and (iv) the written notice of the dispute.

(e) The Independent Expert shall make its determination by written decision within fifteen (15) days following receipt of the materials (the “Independent Expert Decision”). The Independent Expert Decision with respect to the disputed matters shall be limited to the selection of the single proposal for the resolution of the aggregate disputed matters proposed by a Party that best reflects the terms and provisions of this Agreement (i.e., the Independent Expert must select either Buyer’s proposal or Seller’s proposal for resolution of the aggregate disputed matters).

(f) The Independent Expert shall act as an expert for the limited purpose of determining the specific matters submitted for resolution herein and shall not be empowered to award damages, interest, or penalties to either Party with respect to any matter.

The lowest cost Remediation may include taking no action, leaving the condition unaddressed, periodic monitoring or the recording of notices in lieu of remediation, if such responses are allowed under Environmental Laws. Notwithstanding anything to the contrary in this Agreement, the aggregate Remediation Amounts attributable to the effects of all Environmental Defects upon any Environmental Defect Property shall not exceed the Allocated Value of such Environmental Defect Property.
