(a) From and after the Execution Date, and subject to the terms of Sections 6.1 and 6.4 and this Section 3.4, Purchaser shall have the right to conduct, or cause Sport Environmental (the “Environmental Consultant”), to conduct, an inspection of the environmental condition and compliance status of the Assets, including with respect to the operations, use, maintenance and development thereof (the “Environmental Review”), which may include conducting a Phase I Environmental Site Assessment in accordance with the American Society for Testing and Materials (A.S.T.M.) Standard Practice Environmental Site Assessments: Phase I Environmental Site Assessment Process (Publication Designation: E1527-21 or E2247-23) (“Phase I”) and a customary visual thermal camera survey or FLIR camera survey of the Assets. With respect to any Assets that are operated by a Third Party, Seller shall use commercially reasonable efforts to obtain permission from such Third Party operator of such Asset(s) for Purchaser and/or the Environmental Consultant to conduct the Environmental Review with respect to such Asset(s); provided, however, that Seller shall have no liability to Purchaser for failure to obtain such Third Party operator’s permission so long as Seller has uses its commercially reasonable efforts to obtain permission from the applicable Third Party operator of such Asset(s) for Purchaser and/or the Environmental Consultant to conduct the Environmental Review with respect to such Asset(s) (and, for purposes of clarity, Seller shall not be required to make any payments or undertake any obligations for the benefit of any Third Party with respect to such access to such non-operated Assets).

In performing its Environmental Review, Purchaser shall (and shall cause the Environmental Consultant and Purchaser’s other Representatives to): (I) perform all work in a safe and workmanlike manner; (II) perform all work in such a way as to not unnecessarily and unreasonably interfere with the operation of any Property or the business of Seller; (III) materially comply with all applicable Laws; and (IV) at its sole cost, risk, and expense, with respect to any physical damages or disturbances caused by the Environmental Review, repair any disturbances or damages to the Properties caused by the Environmental Review.

(b) Purchaser shall provide to Seller (free of cost) copies of any final environmental reports generated by the Environmental Consultant with respect to any Environmental Defect asserted by Purchaser hereunder, if applicable. Except (i) as may be required or permitted pursuant to the exercise of the rights and fulfillment of the obligations of a Party under this Agreement, (ii) as may be required by applicable Law, or (iii) for information which is or becomes public knowledge through no fault of the Person against whom this sentence is sought to be enforced, Purchaser and Seller and their respective Affiliates shall maintain, and shall cause its and their respective officers, directors, employees, contractors, consultants (including, with respect to Purchaser, the Environmental Consultant), and other Representatives to maintain, all information, reports (whether interim, draft, final, or otherwise), data, work product, and other matters obtained or generated from or attributable to the Environmental Review (the “Environmental Information”) strictly confidential, and shall not disclose all or any portion of the Environmental Information to any Third Party without the prior written consent of Purchaser or Seller, as applicable, which consent shall not be unreasonably withheld or delayed. If this Agreement is terminated prior to the Closing, Purchaser shall continue to be subject to the confidentiality provisions in this Section 3.4(b) and shall deliver the Environmental Information to Seller, which Environmental Information shall become the sole property of Seller. Each Party shall be responsible for the compliance of its Affiliates, and its and their respective officers, directors, employees, contractors, consultants (including, with respect to Purchaser, the Environmental Consultant), and other Representatives with the terms of this Section 3.4(b) that are applicable to such Persons. If the Closing occurs, the foregoing confidentiality obligations set forth in this Section 3.4(b) shall not apply to Purchaser and its Affiliates and its and their respective officers, directors, employees, contractors, consultants and other Representatives, but shall, for purposes of clarity, remain in full force and effect with respect to Seller and its Affiliates and its and their respective officers, directors, employees, contractors, consultants and other Representatives.

The wells, materials, and equipment located on the Properties or included in the Assets may contain hazardous materials, including asbestos and NORM. Hazardous materials, including asbestos and NORM, may have come into contact with various environmental media, including water, soils, or sediment. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT OR ANY OTHER TRANSACTION AGREEMENT, SELLER DOES NOT MAKE, SELLER EXPRESSLY DISCLAIMS, AND PURCHASER WAIVES, ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, WITH RESPECT TO THE PRESENCE OR ABSENCE OF ASBESTOS OR NORM IN OR ON THE ASSETS IN QUANTITIES TYPICAL FOR OILFIELD OPERATIONS IN THE AREAS WHERE THE ASSETS ARE LOCATED. AS OF CLOSING, PROVIDED SELLER HAS SUBSTANTIALLY COMPLIED WITH ITS ACCESS-RELATED OBLIGATIONS CONTAINED IN THIS AGREEMENT PURCHASER SHALL HAVE INSPECTED AND UPON CLOSING SHALL BE DEEMED TO HAVE WAIVED ITS RIGHT TO INSPECT THE ASSETS FOR ALL PURPOSES, AND SHALL BE DEEMED TO HAVE SATISFIED ITSELF AS TO THEIR PHYSICAL AND ENVIRONMENTAL CONDITION, BOTH SURFACE AND SUBSURFACE, INCLUDING CONDITIONS SPECIFICALLY RELATING TO THE PRESENCE, RELEASE, OR DISPOSAL OF HAZARDOUS SUBSTANCES, SOLID WASTES, ASBESTOS, OTHER MAN-MADE FIBERS, AND NORM. PURCHASER IS RELYING SOLELY UPON THE TERMS OF THIS AGREEMENT AND ITS OWN INSPECTION OF THE ASSETS.

3.5 Environmental Defects. As used in this Agreement, the term “Environmental Defect” means (a) any condition, matter, obligation, event or circumstance with respect to all or any portion of any of the Assets that causes such Asset(s) (or Seller, with respect to such Asset(s)) to be in violation of any Environmental Law or not to be in compliance with, or to be subject to a remedial or corrective action obligation pursuant to, any Environmental Law or (b) the existence as of the Defect Claim Date with respect to the Assets or the operation thereof of any environmental pollution, contamination or degradation in excess of standards permitted under any Environmental Law; provided, however, that the term “Environmental Defect” shall not include (i) current obligations to plug or abandon any well, (ii) the presence of NORM or asbestos, as described in Section 3.4(c), other than with respect to the presence of NORM or asbestos in quantities that presently require remediation or abatement under Environmental Law, or (iii) the matters that are disclosed on Schedule 3.5 as of the Execution Date.

3.6 Notice of Title and Environmental Defects and Benefits; Adjustment.

(a) To assert a claim for a Title Defect, Purchaser must deliver a defect claim notice or notices (each, a “Title Defect Claim Notice”) to Seller on or before 5:00 p.m. local time in Fort Worth, Texas, on September 10, 2024 (the “Defect Claim Date”). Each such Title Defect Claim Notice shall be in writing and shall include:

Notwithstanding anything to the contrary in this Agreement, an immaterial failure of any Title Defect Claim Notice to include any of the information or documentation identified or described in Section 3.6(a)(i) through Section 3.6(a)(v) above shall not render such Title Defect Claim Notice void or ineffective so long as such Title Defect Claim Notice is otherwise reasonably sufficient to provide notice to Seller of the existence, nature, and Purchaser’s good faith estimate of the applicable Title Defect(s) and Title Defect Amount(s) asserted therein.

SUBJECT TO, AND WITHOUT LIMITATION OF, THE TITLE MATTERS, AND EXCEPT FOR INSTANCES OF FRAUD (AS DEFINED HEREIN), PURCHASER SHALL BE DEEMED TO HAVE WAIVED AND RELEASED, AND COVENANTS THAT IT SHALL WAIVE AND RELEASE, ANY AND ALL TITLE DEFECTS OR OTHER DEFICIENCIES OR DEFECTS IN SELLER’S TITLE TO THE PROPERTIES (AND ANY ADJUSTMENTS TO THE UNADJUSTED PURCHASE PRICE ATTRIBUTABLE THERETO) FOR WHICH SELLER HAS NOT RECEIVED, ON OR BEFORE THE DEFECT CLAIM DATE, A VALID TITLE DEFECT CLAIM NOTICE THAT IS REASONABLY SUFFICIENT TO PROVIDE NOTICE TO SELLER OF THE EXISTENCE, NATURE, AND PURCHASER’S GOOD FAITH ESTIMATE OF THE TITLE DEFECT(S) AND TITLE DEFECT AMOUNT(S) ASSERTED IN SUCH TITLE DEFECT CLAIM NOTICE.

(b) Should (x) Purchaser obtain knowledge of any Title Benefit on or before the Defect Claim Date or (y) Seller first obtain knowledge of any Title Benefit after the Execution Date and on or before the Defect Claim Date, then such Party shall, on or before the Defect Claim Date, deliver to the other Party a written notice of such alleged Title Benefit including:

(i) a description of the alleged Title Benefit;

(ii) the Well(s) or Lease(s) (limited to the applicable Target Interval(s)) affected thereby;

(iii) the Allocated Value of the Property subject to such alleged Title Benefit;

(iv) copies of supporting documents reasonably sufficient for the other Party (as well as any attorney or examiner hired by the other Party) to verify the existence of the alleged Title Benefit(s); and

(v) such notifying Party’s good faith estimate of the Title Benefit Amount attributable to such alleged Title Benefit and the computations and information upon which Purchaser’s estimate is based.

Notwithstanding anything to the contrary in this Agreement, an immaterial failure of any Title Benefit notice to include any of the information or documentation identified or described in Section 3.6(b)(i) through Section 3.6(b)(v) above shall not render such Title Benefit notice void or ineffective so long as such Title Benefit notice is otherwise reasonably sufficient to provide notice to the applicable other Party of the existence, nature, and the applicable notifying Party’s good faith estimate of the applicable Title Benefit(s) and Title Benefit Amount(s) asserted therein.

SELLER SHALL BE DEEMED TO HAVE WAIVED AND RELEASED, AND COVENANTS THAT IT SHALL WAIVE AND RELEASE, ANY AND ALL TITLE BENEFITS OF WHICH NO PARTY HAS RECEIVED ON OR BEFORE THE DEFECT CLAIM DATE A VALID TITLE BENEFIT NOTICE THAT IS REASONABLY SUFFICIENT TO PROVIDE NOTICE TO THE OTHER PARTY OF THE EXISTENCE, NATURE, AND GOOD FAITH ESTIMATE OF THE TITLE BENEFIT(S) AND TITLE BENEFIT AMOUNT(S) ASSERTED IN SUCH TITLE BENEFIT NOTICE, EXCEPT TO THE EXTENT PURCHASER HAS FAILED TO GIVE A NOTICE WHICH IT WAS OBLIGATED TO GIVE UNDER THIS SECTION 3.6(b).

(c) To assert a claim for an Environmental Defect, Purchaser must, on or before the Defect Claim Date, deliver to Seller one or more notices relating to Environmental Defects (each, an “Environmental Defect Claim Notice”), which Environmental Defect Claim Notices shall be in writing and shall include:

-25-

(i) a description of the alleged Environmental Defect, including the applicable Environmental Law(s) alleged to be violated and/or implicated thereby and the facts that Purchaser believes substantiate the existence of such alleged Environmental Defect;

(ii) the Asset(s) affected by such alleged Environmental Defect (each, an “Environmental Defect Asset”);

(iii) such supporting documentation and/or Environmental Information as is reasonably sufficient for Seller (as well as any consultant hired by Seller) to evaluate the alleged Environmental Defect (any and all of which supporting documents may be furnished via access to a web link or ftp site (in lieu of other means of delivery));

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

Notwithstanding anything to the contrary in this Agreement, an immaterial failure of any Environmental Defect Claim Notice to include any of the information or documentation identified or described in Section 3.6(c)(i) through Section 3.6(c)(iv) above shall not render such Environmental Defect Claim Notice void or ineffective so long as such Environmental Defect Claim Notice is otherwise reasonably sufficient to provide notice to Seller of the existence, nature and Purchaser’s good faith estimate of the applicable Environmental Defect(s) and Environmental Defect Amount(s) asserted therein.

SUBJECT TO, AND WITHOUT LIMITATION OF, THE ENVIRONMENTAL MATTERS, AND EXCEPT FOR INSTANCES OF FRAUD (AS DEFINED HEREIN), PURCHASER SHALL BE DEEMED TO HAVE WAIVED AND RELEASED, AND COVENANTS THAT IT SHALL WAIVE AND RELEASE, ANY AND ALL ENVIRONMENTAL DEFECTS AND OTHER DEFECTS OR DAMAGES RELATED TO THE ENVIRONMENTAL CONDITION OF THE ASSETS (AND ANY ADJUSTMENTS TO THE UNADJUSTED PURCHASE PRICE ATTRIBUTABLE THERETO) FOR WHICH SELLER HAS NOT RECEIVED ON OR BEFORE THE DEFECT CLAIM DATE A VALID ENVIRONMENTAL DEFECT CLAIM NOTICE THAT IS REASONABLY SUFFICIENT TO PROVIDE NOTICE TO SELLER OF THE EXISTENCE, NATURE, AND PURCHASER’S GOOD FAITH ESTIMATE OF THE ENVIRONMENTAL DEFECT(S) AND ENVIRONMENTAL DEFECT AMOUNT(S) ASSERTED IN SUCH ENVIRONMENTAL DEFECT CLAIM NOTICE.

(d) Purchaser agrees to use commercially reasonable efforts to provide Seller, on or before the end of each calendar week prior to the Defect Claim Date, written notice of all alleged Title Defects and alleged Environmental Defects discovered by Purchaser during such calendar week, which notice may be preliminary in nature and may be amended, supplemented, replaced and/or withdrawn (in-whole or in-part), in Purchaser’s discretion, at any time on or prior to the Defect Claim Date and provided that, notwithstanding anything to the contrary herein, any failure of Purchaser to provide any such preliminary notice to Seller shall not be deemed or construed to waive, limit, restrict or otherwise prejudice Purchaser’s right to assert any Title Defect or Environmental Defect at any time on or prior to the Defect Claim Date. In addition, Purchaser shall be entitled, at its discretion at any time prior to Closing, to withdraw, in whole or in part, any Title Defect Claim Notice and/or Environmental Defect Claim Notice and any Title Defect and/or Environmental Defect alleged thereunder that has previously been submitted by Purchaser.

3.7 Cure.

(a) Seller shall have the right, but not the obligation, to attempt, at Seller’s sole cost, risk, and expense, to cure or remove (i) on or before the date that is three (3) days prior to the Target Closing Date (such date, the “Environmental Cure Date”), any alleged Environmental Defects (each such alleged Environmental Defect, a “Cure Target Environmental Defect”) or (ii) on or before the date that is ninety (90) days after the Closing Date (such date, the “Title Cure Date” and, together with the Environmental Cure Date, each, a “Cure Date”, as applicable), any alleged Title Defects (each such alleged Title Defect, a “Cure Target Title Defect” and, together with all Cure Target Environmental Defect, collectively, the “Cure Target Defects”), in each case, of which Seller has been advised by Purchaser pursuant to Sections 3.6(a), 3.6(c) or 3.6(d), as applicable. To exercise any such cure or removal right with

-26-

respect to any Cure Target Title Defects after Closing, Seller shall provide written notice to Purchaser of its intent to attempt to cure or remove any such Cure Target Title Defects on or before 5:00 p.m. local time in Fort Worth, Texas on the date that is at least three (3) days prior to the Target Closing Date. Seller may elect to perform any such environmental cure or removal work with respect to any Cure Target Environmental Defect at any time prior to the Environmental Cure Date by delivering prior written notice thereof to Purchaser. At Closing, (A) all Title Defect Properties that are affected by or subject to any such Cure Target Title Defects shall be included in the Assets to be assigned, conveyed and transferred to Purchaser in connection with Closing and (B) all adjustments to the Unadjusted Purchase Price with respect to such Cure Target Title Defects shall be addressed as provided in Section 3.8(e) for purposes of Closing and thereafter any adjustment required under Section 3.8(a) with respect thereto shall be made pursuant to Section 3.8(f). The election by Seller to attempt to cure or remove one or more of such Cure Target Defects shall not affect the rights and obligations of the Parties under Section 3.10 with respect to dispute resolution related to any such Cure Target Defect. Seller’s election to attempt cure or remove a Cure Target Defect shall not constitute a waiver of any of the rights of Seller pursuant to this Article 3, including Seller’s right to dispute the existence, nature, or value of such Cure Target Defect.

(b) Subject to, and without limitation of, the Parties’ respective rights under Section 3.10 with respect to any Disputed Matter, including, for purposes of clarity, the determination by the Title Arbitrator or Environmental Arbitrator, as applicable, of the existence of and/or the Title Defect Amount or Environmental Defect Amount with respect to, as applicable, any Cure Target Defect that constitutes a Disputed Matter, to the extent any Cure Target Defect is not cured and/or remediated by Seller on or before the applicable Cure Date, the adjustment required under Section 3.7(e) with respect thereto shall be made pursuant to Section 8.4(e) or Section 8.4(b), as applicable.

(c) Any dispute between Seller and Purchaser relating to whether, and to what extent, a Cure Target Defect has been cured or remediated shall be deemed to constitute a Disputed Matter and shall be resolved as set forth in Section 3.10, except that any such matter shall be submitted to the Title Arbitrator or Environmental Arbitrator, as applicable, on or before the date that is ten (10) Business Days after the applicable Cure Date; provided, however, that any prior or concurrent determination by the Title Arbitrator or Environmental Arbitrator, as applicable, with respect to Cure Target Defects (or factual or legal matters relating thereto, even if determined in connection with the resolution of an otherwise unrelated dispute) which Seller has elected to attempt to cure or remediate pursuant to Section 3.7(a) shall be binding on the Parties with respect to such Cure Target Defect (or factual or legal matters relating thereto, even if determined in connection with the resolution of an otherwise unrelated dispute).

(d) Seller shall have the right to exclude any Environmental Defect Asset (other than the Assets compromising the Parker Central Production Facility and Gas Compression System) from this Agreement by delivery of written notice to Purchaser of the exercise of such right no later than three (3) Business Days prior to the Target Closing Date if Purchaser’s good faith estimate of the Environmental Defect Amount(s) for such Environmental Defect Asset(s), as set forth in the applicable Environmental Defect Claim Notice, in each case, equals or exceeds (i) one hundred percent (100%) of the Allocated Value of the applicable Environmental Defect Asset (if the applicable Environmental Defect Asset has an Allocated Value) or (ii) $75,000 if the applicable Environmental Defect Asset does not have an Allocated Value, and in each such case, the Closing Payment shall be reduced by the Allocated Value of the applicable Environmental Defect Asset (if any) and such applicable Environmental Defect Asset shall be deemed deleted from the Exhibits and Schedules hereto and constitute an “Excluded Asset” for all purposes of this Agreement; provided, however, that, notwithstanding the foregoing, Seller shall have no right to exclude any such Environmental Defect Asset if, and only if, (A) Purchaser determines in good faith that the exclusion of such Environmental Defect Asset would materially and adversely affect Purchaser’s ownership, operation and/or use of any other Assets (or any group of Assets) in any material respect following Closing and (B) the aggregate downward adjustment to the Purchase Price associated with all Environmental Defect Asset(s) addressed in subpart (A) of this Section 3.7(d) (for the avoidance of doubt, if such Environmental Defect Asset(s) were not excluded from this Agreement) would be less than One Million Dollars ($1,000,000), in which case such Environmental Defect Asset(s) will be conveyed to Purchaser at Closing in accordance with the terms of this Agreement. If, following Closing but prior to the Title Cure Date, Seller is able to cure or remove all Environmental Defects with respect to any Environmental Defect Asset that was excluded from Closing pursuant to this Section 3.7(d), then, prior to the date of the final adjustment to the Unadjusted Purchase Price under Section 8.4(b) or Section 8.4(c), as applicable, (1) Seller shall, promptly after such Environmental Defects are cured or removed from an Environmental Defect Asset, convey the applicable Environmental Defect Asset to Purchaser, (2) the Parties shall deliver all instruments and documents

-27-

that would have been required under the terms hereof to be delivered at Closing with respect to such Environmental Defect Asset at such delayed Closing; (3) Purchaser shall, simultaneously with the conveyance of the applicable Environmental Defect Asset, pay the amount of any previous deduction from the Unadjusted Purchase Price (subject to all other applicable adjustments with respect to such Environmental Defect Asset under this Agreement) to Seller in cash, and (4) such Environmental Defect Asset shall no longer be deemed to be an Excluded Asset for any purposes hereunder.

(e) Seller shall have the right to exclude any Title Defect Property that constitutes a Lease or Well from this Agreement by delivery of written notice to Purchaser of the exercise of such right no later than three (3) Business Days prior to the Target Closing Date if Purchaser’s good faith estimate of the Title Defect Amount(s) for such Title Defect Property(s), as set forth in the applicable Title Defect Claim Notice equals or exceeds seventy-five percent (75%) of the Allocated Value of the applicable Title Defect Property, and, in such case, the Closing Payment shall be reduced by the Allocated Value of the applicable Title Defect Property and such applicable Title Defect Property shall be deemed deleted from the Exhibits and Schedules hereto and constitute an “Excluded Asset” for all purposes of this Agreement. If, following Closing but prior to the Title Cure Date, Seller is able to cure or remove all Title Defects with respect to any Title Defect Property that was excluded from Closing pursuant to this Section 3.7(e), then, prior to the date of the final adjustment to the Unadjusted Purchase Price under Section 8.4(b) or Section 8.4(c), as applicable, (A) Seller shall, promptly after such Title Defects are cured or removed from a Title Defect Property, convey the applicable Title Defect Property 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 Title Defect Property at such delayed Closing; (C) Purchaser shall, simultaneously with the conveyance of the applicable Title Defect Property, pay the amount of any previous deduction from the Unadjusted Purchase Price (subject to all other applicable adjustments with respect to such Title Defect Property under this Agreement) to Seller in cash, and (D) such Title Defect Property shall no longer be deemed to be an Excluded Asset for any purposes hereunder.

3.8 Adjustment for Title Defects and Benefits and Environmental Defects.

(a) With respect to each Property for which any Title Defect or Environmental Defect has been alleged under Section 3.6(a) or 3.6(c), such Property shall, subject to Seller’s exercise of its right in Section 3.7(d) with respect to any applicable Environmental Defect Asset or Section 3.7(e) with respect to any applicable Title Defect Property, be assigned at Closing subject to all uncured Title Defects and Environmental Defects, and the Purchase Price shall be reduced at Closing by (i) in the case of Title Defects, an amount determined pursuant to Section 3.9(a) (the “Title Defect Amount”), and (ii) in the case of Environmental Defects, an amount determined pursuant to Section 3.9(c) (the “Environmental Defect Amount”), in each case, as provided in Sections 3.8(d), 3.8(e) and 3.8(f), as applicable; provided, however, that, notwithstanding the foregoing, without limitation of Section 3.8(e), no other reduction shall be made in the Unadjusted Purchase Price at Closing with respect to any Title Defect or Environmental Defect which (A) Seller elects to cure following Closing pursuant to Section 3.7(a) (solely with respect to Title Defects) or (B) are Disputed Matters.

(b) With respect to each Property affected by Title Benefits reported under Section 3.6(b), there shall be an offset to Title Defects and Environmental Defects by an amount as determined pursuant to Section 3.9(b) (the “Title Benefit Amount”); provided, however, that, notwithstanding anything in this Agreement to the contrary, in no event shall any Title Benefit Amount(s) result in any increase to the Unadjusted Purchase Price.

(c) Seller and Purchaser shall use their respective commercially reasonable efforts and cooperate in good faith to attempt to agree upon the existence of any Title Defects, Title Benefits or Environmental Defects reported pursuant to Sections 3.6(a), 3.6(b) and 3.6(c), as applicable, and any corresponding Title Defect Amounts, Title Benefit Amounts, and Environmental Defect Amounts, in each case, on or before the Closing Date. If Seller and Purchaser are unable to agree by the Closing Date, then, subject to Section 3.7, the Title Defects, Title Benefits, Environmental Defects, reported pursuant to Sections 3.6(a), 3.6(b) and 3.6(c), as applicable, and any corresponding Title Defect Amounts, Title Benefit Amounts, and Environmental Defect Amounts which are then in dispute (each a “Disputed Matter”) shall be exclusively and finally resolved by arbitration pursuant to Section 3.10.

(d) At Closing, the Unadjusted Purchase Price shall be adjusted (i) in accordance with Section 3.8(a) with respect to any Title Defects which (A) Seller has not elected to attempt to cure pursuant to Section 3.7(a) and (B) are not Disputed Matters, (ii) in accordance with Section 3.8(b) with respect to any Environmental Defects which (A) Seller has not cured as of the Closing Date and (B) are not Disputed Matters and (iii) in accordance with Section 3.8(b) with respect to any Title Benefits which are not Disputed Matters.

-28-

(e) At Closing, an amount equal to the sum of all Title Defect Amounts and Environmental Defect Amounts (as asserted in good faith by Purchaser in the applicable Title Defect Claim Notices and Environmental Defect Claim Notices provided in accordance with Sections 3.6(a) and/or 3.6(c), as applicable) related to (i) any Cure Target Title Defects which Seller elects to attempt to cure prior to the Title Cure Date in accordance with Section 3.7(a) or (ii) which are Disputed Matters (such aggregate amount, the “Defect Escrow Amount”), shall be (A) first retained by the Escrow Agent from the Deposit at Closing and (B) thereafter, deducted in the calculation of the Closing Payment as provided in Section 8.4(e). As contemplated by Section 8.4(b), any such deduction shall be made by reducing the portion of the Purchase Price payable at Closing by an amount equal to the portion of the Defect Escrow Amount not retained from the Deposit and, at the Closing, Purchaser shall deposit the portion of the Defect Escrow Amount so deducted into separate escrow account established with the Escrow Agent (the “Defect Escrow Account”), to be governed by the Deposit Escrow Agreement. The Defect Escrow Amount shall be held, invested and disbursed in accordance with the terms of this Article 3 and the Deposit Escrow Agreement pending the curing and/or resolution, as applicable, of the applicable Cure Target Title Defects and/or the applicable Disputed Matters in accordance with the applicable terms of this Article 3.

(f) After Closing, the Purchase Price shall be adjusted for (i) any Cure Target Title Defects which (A) Seller elects to attempt to cure prior to the Title Cure Date pursuant to Section 3.7(a) or (B) are Disputed Matters and (ii) any Environmental Defects or Title Benefits which are Disputed Matters, in each case, to the extent the Title Defect Amounts, Title Benefit Amounts and Environmental Defect Amounts for such Title Defects, Title Benefits and Environmental Defects are included in the Defect Escrow Amount, as provided in this Section 3.8(f). Within ten (10) Business Days after the later to occur of (x) the Title Cure Date and (y) the final date of determination of all Disputed Matters submitted to a Title Arbitrator or Environmental Arbitrator pursuant to Section 3.10, as applicable, and after consideration of all other adjustments previously made to the Unadjusted Purchase Price and after giving effect to all applicable limitations set forth in Section 3.9, the Parties shall execute joint written instructions to the Escrow Agent instructing it to deliver to Seller or Purchaser, as applicable, the portion of the Defect Escrow Amount equal to the net amount which such Party is entitled to receive in order to make the adjustments to the Unadjusted Purchase Price called for pursuant to this Section 3.8(f), with respect to (1) any Disputed Matters, as determined by the applicable Title Arbitrator or Environmental Arbitrator under Section 3.10(a) and/or Section 3.10(b), as applicable, and (2) any Cure Target Title Defects which Seller elected to attempt to cure prior to the Title Cure Date pursuant to Section 3.7(a) and which are not Disputed Matters after considering the extent such Title Defects have been cured pursuant to Section 3.6(c). Any payment made pursuant to this Section 3.8(f) shall be made by wire transfer of immediately available funds to a bank account or accounts to be designated in writing by the Party receiving such payment (which bank account or account(s) shall, for purposes of clarity, be designated by such Party in the applicable executed joint written instructions delivered to the Escrow Agent instructing it to deliver such payment to such Party).

(g) The Parties shall treat for U.S. federal and applicable state and local income Tax purposes, any amount paid pursuant to this Section 3.8 as an adjustment to the Purchase Price.

(h) SUBJECT TO, AND WITHOUT LIMITATION OF, THE ENVIRONMENTAL MATTERS, THE TITLE MATTERS, THE CONDITION TO CLOSING IN SECTION 7.2(d), PURCHASER’S RIGHTS AND REMEDIES UNDER THE R&W INSURANCE POLICY AND EXCEPT FOR INSTANCES OF FRAUD (AS DEFINED IN THIS AGREEMENT), (X) THIS ARTICLE 3 SHALL, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, OTHERWISE BE THE EXCLUSIVE RIGHT AND REMEDY OF THE PURCHASER GROUP WITH RESPECT TO TITLE DEFECTS AND OTHER DEFICIENCIES IN TITLE TO THE ASSETS AND ANY ENVIRONMENTAL DEFECTS AND OTHER DEFECTS OR DAMAGES RELATED TO THE ENVIRONMENTAL CONDITION OF THE ASSETS AND (Y) EXCEPT AS PROVIDED IN SECTION 3.6(a) AND SECTION 3.6(c), BUT SUBJECT TO THE FOREGOING TERMS OF THIS SECTION 3.8(h), PURCHASER OTHERWISE RELEASES, REMISES, AND FOREVER DISCHARGES SELLER, ITS AFFILIATES, AND EACH OF THEIR RESPECTIVE MEMBERS, SHAREHOLDERS, INTEREST OWNERS, OFFICERS, DIRECTORS, MANAGERS, EMPLOYEES, AGENTS, ADVISORS, AND REPRESENTATIVES FROM ANY AND ALL SUITS, LEGAL OR ADMINISTRATIVE PROCEEDINGS, CLAIMS, DEMANDS, DAMAGES, LOSSES,

COSTS, LIABILITIES, INTEREST, OR CAUSES OF ACTION WHATSOEVER, IN LAW OR IN EQUITY, KNOWN OR UNKNOWN, WHICH PURCHASER MIGHT NOW OR SUBSEQUENTLY MAY HAVE, BASED ON, RELATING TO, OR ARISING OUT OF, ANY TITLE DEFECT, ENVIRONMENTAL DEFECT, OR OTHER DEFICIENCY IN TITLE TO, OR OTHER DEFECTS OR DAMAGES RELATED TO THE ENVIRONMENTAL CONDITION OF, ANY ASSET.

3.9 Calculation of Title Defect Amounts, Title Benefit Amounts, and Environmental Defect Amounts.

(a) The Title Defect Amount resulting from a Title Defect shall be determined as follows:

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

(ii) if the Title Defect is a lien, encumbrance, or other charge which is liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from Seller’s interest in the affected Property;

(iii) if the Title Defect represents a discrepancy between (A) Seller’s aggregate ownership of Net Acres for any Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) and (B) the amount of Net Acres set forth for such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) in Schedule 2.2, and there is no discrepancy between the aggregate Net Revenue Interest of Seller in such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) and the Net Revenue Interest set forth for such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) in Schedule 2.2, then the Title Defect Amount shall be the product of the Allocated Value of such Lease multiplied by a fraction, the numerator of which is the difference between the number of Net Acres owned by Seller in such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) and the number of Net Acres set forth for such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) in Schedule 2.2, and the denominator of which is the Net Acres set forth for such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) in Schedule 2.2;

(iv) if (x) the Title Defect represents a discrepancy between (A) Seller’s aggregate Net Revenue Interest for any Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) or Well and (B) the Net Revenue Interest stated in Schedule 2.2 for such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) or Well, and (y) there is a proportionate decrease in Seller’s Working Interest or Net Acre ownership, as applicable, for such applicable Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) or Well from that set forth in Schedule 2.2 for such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) or Well, then the Title Defect Amount shall be the product of the Allocated Value of such Lease or Well multiplied by a fraction, the numerator of which is the decrease in Seller’s aggregate Net Revenue Interest in such Lease or Well and the denominator of which is Seller’s Net Revenue Interest stated in Schedule 2.2 for such Lease or Well; provided, however, that if the Title Defect does not affect such Lease or Well throughout its entire productive life, the Title Defect Amount determined under this Section 3.9(a)(iv) shall be reduced to take into account the applicable time period only;

(v) if the Title Defect represents an obligation, encumbrance, burden, or charge upon, or other defect in title to, the affected Property of a type not described in subsections (i), (ii), (iii), or (iv) of this Section 3.9, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Property so affected, the portion of Seller’s interest in the Property affected by the Title Defect, the legal effect of the Title Defect, the potential discounted economic effect of the Title Defect over the productive life of the affected Property, the values placed upon the Title Defect by Purchaser and Seller, the age of the factual matters causing or constituting the alleged Title Defect, the probability that title failure will occur with respect to any Title Defect that represents only a possibility of title failure, and such other factors as are necessary to make a proper evaluation;

-30-

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

(vii) notwithstanding anything to the contrary in this Article 3:

(A) an individual claim for a Title Defect for which a valid Title Defect Claim Notice is given prior to the Defect Claim Date shall only generate an adjustment to the Unadjusted Purchase Price under this Article 3 if the Title Defect Amount with respect thereto exceeds Fifty Thousand Dollars ($50,000) with respect to the Leases (the “Individual Lease Defect Threshold”) and One Hundred Fifty Thousand Dollars ($150,000) with respect to the Wells (the “Individual Well Defect Threshold” and together with the Individual Lease Defect Threshold, collectively referred to, as applicable, the “Individual Defect Threshold”); provided, however, that (I) if a specific Title Defect affects more than one Title Defect Property, then the Title Defect Amounts associated with the specific Title Defect may be aggregated by Purchaser for determining whether the Individual Defect Threshold is met with respect to all such Properties affected by such specific Title Defect, and (II) if a specific Title Defect affects more than one Target Interval within a Title Defect Property, then the Title Defect Amount shall be aggregated to take into account the effect of such Title Defect on all Target Intervals for determining whether the Individual Defect Threshold is met;

(B) except with respect to Title Defects described in Section 3.9(a)(ii), the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any given Property shall not exceed the Allocated Value of such Property;

(C) there shall be no adjustment to the Purchase Price for Title Defects or Environmental Defects unless and until the aggregate of all Title Defect Amounts and Environmental Defect Amounts that exceed (or are deemed to exceed) the Individual Defect Threshold less the aggregate of all Title Benefit Amounts that exceed the Title Benefit Threshold, exceeds an amount equal to two percent (2%) of the Unadjusted Purchase Price (“Aggregate Deductible”), and then only to the extent that such aggregate amount exceeds the Aggregate Deductible. For purposes of this Section 3.9(a)(vii)(C), the Unadjusted Purchase Price shall be reduced by the Allocated Value of any Assets excluded pursuant to Section 3.4(a), 3.7(d), or 3.7(e) and references to the Unadjusted Purchase Price in this Section 3.9(a)(vii)(C) shall be deemed and construed to reference the Unadjusted Purchase Price as reduced by any such reductions described herein; and

(D) if any Title Defect relates to an event, fact, or circumstance that would also give rise to a breach of Seller’s representations and warranties contained in Section 4.24 with respect to the special warranty of Defensible Title, then such Title Defect shall not be subject to the Individual Defect Threshold or the Aggregate Deductible.

(b) The Title Benefit Amount resulting from a Title Benefit shall be determined as follows:

(i) if Purchaser and Seller agree in writing upon the Title Benefit Amount, that amount shall be the Title Benefit Amount;

(ii) if the Title Benefit represents a discrepancy between (A) Seller’s aggregate Net Acre ownership in any Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) and (B) the amount of Net Acres shown for such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) in Schedule 2.2, and there is no discrepancy between the aggregate Net Revenue Interest of Seller in

-31-

such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) and the Net Revenue Interest set forth for such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) in Schedule 2.2, then the Title Benefit Amount shall be the product of the Allocated Value of such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) multiplied by a fraction, the numerator of which is difference between the number of Net Acres owned by Seller in such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) and the number of Net Acres set forth for such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) in Schedule 2.2, and the denominator of which is the Net Acres set forth for such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) in Schedule 2.2;

(iii) if (x) the Title Benefit represents a discrepancy between (A) the Net Revenue Interest for any Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) or Well and (B) the Net Revenue Interest stated with respect to such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) or Well, as applicable, in Schedule 2.2, and (y) there is a proportionate increase in Seller’s Working Interest, for such applicable Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) or Well from that set forth in Schedule 2.2 for such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) or Well, then the Title Benefit Amount shall be the product of the Allocated Value of the affected Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) or Well multiplied by a fraction, the numerator of which is the increase in Seller’s aggregate Net Revenue Interest in such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) or Well and the denominator of which is the Net Revenue Interest stated in Schedule 2.2 with respect to such Lease (as to the applicable Target Interval(s) (except as otherwise expressly set forth on Schedule 2.2 with respect to such Lease)) or Well; provided, however, that if the Title Benefit does not affect a Lease or Well throughout the entire productive life of thereof, the Title Benefit Amount determined under this Section 3.9(b)(iii) shall be reduced to take into account the applicable time period only;

(iv) if a Title Benefit represents a right, circumstance, or condition of a type not described in subsections (i), (ii) or (iii) of this Section 3.9(b), the Title Benefit Amount shall be determined by taking into account the Allocated Value of the Property so affected, the portion of Seller’s interest in the Property so affected, the legal effect of the Title Benefit, the potential discounted economic effect of the Title Benefit over the productive life of any affected Property, the values placed upon the Title Benefit by Purchaser and Seller, and such other factors as are necessary to make a proper evaluation; and

(v) notwithstanding anything to the contrary in this Article 3, an individual claim for a Title Benefit shall only serve to offset the any applicable Title Defect Amounts and/or Environmental Defect Amounts if the Title Benefit Amount with respect thereto exceeds Seventy-Five Thousand Dollars ($75,000) (the “Title Benefit Threshold”).

(c) The Environmental Defect Amount resulting from an Environmental Defect shall be determined as follows:

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

(ii) the Environmental Defect Amount shall include, but shall not exceed, the reasonable cost of the response required or allowed under Environmental Laws in effect on the Execution Date that addresses and resolves (for current and future use in the same manner as currently used) the applicable Environmental Defect with the most cost-effective remediation of such Environmental Defect (considered as a whole, taking into consideration any material impacts such response may have on the continued, safe, and prudent operation of the relevant Assets and any potential material additional costs or liabilities that may likely arise as a direct result of such response);

-32-

(iii) the Environmental Defect Amount with respect to an Environmental Defect shall be determined without duplication of any costs or losses included in another Environmental Defect Amount or adjustment to the Purchase Price hereunder; and

(iv) notwithstanding anything to the contrary in this Article 3, but subject to Section 3.9(a)(vii)(C), an individual claim for an Environmental Defect for which a valid Environmental Defect Claim Notice is given prior to the Defect Claim Date shall only generate an adjustment to the Unadjusted Purchase Price if the Environmental Defect Amount with respect thereto exceeds the Individual Environmental Defect Threshold.

3.10 Dispute Resolution.

(a) Except as otherwise provided in Section 3.7(c), with respect to any Disputed Matter concerning Title Defects, Title Benefits, Title Defect Amounts and/or Title Benefit Amounts (collectively, “Disputed Title Matters”), on or after the date that is ten (10) Business Days following the Closing Date, either Party may notify the other Party of its election to submit all remaining Disputed Title Matters to a title attorney with at least ten (10) years’ experience in oil and gas titles in the State of Texas, as selected by mutual agreement of Purchaser and Seller (the “Title Arbitrator”) and thereafter the Parties shall promptly submit such remaining Disputed Title Matters to the Title Arbitrator. If Purchaser and Seller have not agreed upon a Person to serve as Title Arbitrator within ten (10) Business Days of a Party’s election to submit such Disputed Title Matters to the Title Arbitrator, the Parties shall, within five (5) Business Days after the end of such ten (10) Business Day period, formally apply to the Houston, Texas office of the American Arbitration Association (or in the event that there is no such office in Houston, Texas at such time, to any other office of the American Arbitration Association) to choose the Title Arbitrator and submit such Disputed Title Matters along with such application. The Title Arbitrator shall not have worked as an employee or outside counsel for any Party or its Affiliates during the five (5) year period preceding the arbitration or have any financial interest in the dispute other than the payment of the Title Arbitrator’s fees and expenses incurred as Title Arbitrator.

(b) Except as provided in Section 3.7(c), with respect to any Disputed Matter concerning Environmental Defects and Environmental Defect Amounts (collectively, “Disputed Environmental Matters”), on or after a date that is ten (10) Business Days following the Closing Date, either Party may notify the other Party of its election to submit all remaining Disputed Environmental Matters to a reputable environmental consultant with at least ten (10) years’ experience in corrective environmental action regarding oil and gas properties in the State of Texas, as selected by mutual agreement of Purchaser and Seller (the “Environmental Arbitrator”), and thereafter the Parties shall promptly submit such remaining Disputed Environmental Matters to the Environmental Arbitrator. If Purchaser and Seller have not agreed upon a Person to serve as Environmental Arbitrator within ten (10) Business Days of a Party’s election to submit such Disputed Environmental Matters to the Environmental Arbitrator, the Parties shall, within five (5) Business Days after the end of such ten (10) Business Day period, formally apply to the Houston, Texas office of the American Arbitration Association to choose the Environmental Arbitrator and submit such Disputed Environmental Matters along with such application. The Environmental Arbitrator shall not have worked as an employee or outside consultant for any Party or its Affiliates during the five (5) year period preceding the arbitration or have any financial interest in the dispute other than the payment of the Environmental Arbitrator’s fees and expenses incurred as Environmental Arbitrator.

(c) In each case above, the arbitration proceeding shall be held in Houston, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section 3.10. The Title Arbitrator’s or Environmental Arbitrator’s determination, as applicable, shall be made within forty-five (45) days after submission of the matters in dispute and shall be final and binding upon the Parties, without right of appeal. In making their respective determinations, the Title Arbitrator and the Environmental Arbitrator shall be bound by the provisions of this Article 3 and may consider such other matters as, in the opinion of the Title Arbitrator or Environmental Arbitrator (as applicable), are necessary or helpful to make a proper determination. The Title Arbitrator and

-33-

Environmental Arbitrator may consult with and engage disinterested Third Parties to advise the arbitrator, including petroleum engineers. The Title Arbitrator and Environmental Arbitrator shall act as experts for the limited purpose of determining the specific disputed Title Defect Amounts, Title Benefit Amounts, and Environmental Defect Amounts submitted by any Party and may not award damages, interest, or penalties to any Party with respect to any matter. Seller and Purchaser shall each bear their own legal fees and other costs of presenting their respective cases. The fees, costs and expenses of the Title Arbitrator and Environmental Arbitrator 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 Title Arbitrator or Environmental Arbitrator, as applicable, bears to the amount actually contested by such Party with respect to all applicable disputed matters. The Title Arbitrator may not award Purchaser a greater Title Defect Amount than the Title Defect Amount claimed by Purchaser in its applicable Title Defect Claim Notice or a greater Title Benefit Amount than that claimed by Seller in its position statement delivered to the Title Arbitrator. The Environmental Arbitrator may not award Purchaser a greater Environmental Defect Amount than the Environmental Defect Amount claimed by Purchaser in its applicable Environmental Defect Claim Notice.

3.11 Notice to Holders of Consent and Preferential Purchase Rights. Promptly after the Execution Date (but in any event no later than five (5) Business Days following the Execution Date), Seller shall (a) prepare and send (i) notices to the holders of any Consents (including, for purposes of clarity, the Material Consents and all other consents and similar rights that are set forth on Schedule 4.8(b)) requesting the consent of each such Person to the Transactions (or a waiver of such Consent right) and (ii) notices to the holders of any applicable preferential rights to purchase or similar rights that are applicable to or triggered by any of the Transactions (including, for purposes of clarity, those set forth on Schedule 4.8(a)) in compliance with the terms of such rights and requesting waivers of such rights, in each case, using forms of such notices that are reasonably acceptable to Purchaser and (b) provide Purchaser with a true and complete copy of each such notice promptly after Seller’s delivery thereof in accordance with this Section 3.11. Seller shall use commercially reasonable efforts to obtain all such Consents and similar approvals (or waivers thereof) and waivers of all preferential rights and other similar rights prior to the Target Closing Date; provided, however, that Seller shall not be required to make any payments or undertake any obligations for the benefit of the holders of such rights in order to obtain the required Consents (including Material Consents) and waivers. Upon receipt of Seller’s written request, Purchaser shall use commercially reasonable efforts to cooperate in good faith with Seller in seeking to obtain such any and all such Consents and waivers; provided, however, that Purchaser shall not be obligated to spend any monies or undertake any obligations (other than requesting such Consents and waivers) in connection therewith. Seller covenants and agrees that it shall promptly provide written notice to Purchaser after becoming aware of any actual or threatened dispute, disagreement or proceeding affecting or with respect to any Consent, preferential rights and other similar rights affecting or relating to the Transactions.

3.12 Consent Requirements.

(a) Subject to, and without limitation of, Section 3.12(c), unless the Parties otherwise agree in writing, in no event shall there be transferred at Closing any Asset for which a Material Consent has not been obtained prior to Closing. Seller shall deliver a written notice to Purchaser on or before five (5) Business Days prior to the Target Closing Date setting forth each Material Consent which, as of such date, has not been satisfied or waived (or that is otherwise subject to an actual or threatened dispute) and Purchaser shall thereafter have the continuing right until the date that is one (1) Business Day prior to the Target Closing Date to elect to waive the receipt (or waiver) of any such Material Consent, in which case, such Material Consent shall be deemed to have been obtained prior to Closing with respect to the affected Asset(s) for all purposes of this Agreement.

(b) In cases in which the Asset subject to such an un-obtained Material Consent is an Asset other than a Property, and Purchaser is assigned the Property or Properties to which such Asset relates, but such Asset is not transferred to Purchaser due to the un-waived Material Consent requirement, the Parties shall continue after Closing and until the date of the final adjustment to the Unadjusted Purchase Price under Sections 8.4(b) and/or 8.4(c), as applicable (the “Final Adjustment Date”), to use commercially reasonable efforts to obtain the Material Consent so that such Asset can be transferred to Purchaser upon receipt of the Material Consent (or waiver thereof), and, if permitted pursuant to applicable Law and agreement, such Asset shall be held by Seller for the benefit of Purchaser, Purchaser shall pay all amounts due thereunder or with respect thereto, and Purchaser shall be responsible for the performance of any obligations under or with respect to such Asset to the extent that Purchaser has been transferred the Assets necessary to such performance until the applicable Material Consent is obtained. Notwithstanding the foregoing, neither Party shall be required to make any payments or undertake any obligations for the benefit of the holders of any un-obtained Material Consents subject to this Section 3.12(b) in connection with obtaining (or attempting to obtain) any such Material Consent (or a waiver thereof).

-34-

(c) In cases in which the Asset subject to such a Material Consent requirement is a Property and the Material Consent to the transfer of such Property (or a waiver thereof) is not obtained by Closing, Purchaser shall have the right to elect to exclude the Property subject to such Material Consent and, subject to the remainder of this Section 3.12(c), (i) the affected Property shall not be conveyed to Purchaser at Closing, (ii) the Unadjusted Purchase Price shall be reduced at Closing by the Allocated Value of such Property, (iii) such Property shall be deemed to be deleted from Exhibit A-1, Exhibit A-2 and/or Exhibit A-3 attached hereto, as applicable, and added to Schedule 1.3 attached hereto and (iv) such Property shall constitute an Excluded Asset for all purposes hereunder. The Parties shall continue to use commercially reasonable efforts to obtain the Material Consent so that such Asset can be transferred to Purchaser upon receipt of the Material Consent, and if any such Material Consent requirement with respect to which an adjustment to the Unadjusted Purchase Price is made under Section 2.3(b) is subsequently satisfied (or waived) prior to the date of the final adjustment to the Unadjusted Purchase Price under Section 8.4(b) or Section 8.4(c), as applicable, (A) Seller shall, promptly after such Material Consent requirement is satisfied (or waived), convey the applicable Property 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 Property (or portion thereof) at such delayed Closing; (C) Purchaser shall, simultaneously with the conveyance of the applicable Property (or portion thereof), pay the amount of any previous deduction from the Unadjusted Purchase Price (subject to all other applicable adjustments with respect to such Property (or portion thereof) under this Agreement) to Seller, and (D) such Property shall no longer be deemed to be (x) deleted from Exhibit A-1 and/or Exhibit A-2 attached hereto, (y) added to Schedule 1.3 attached hereto or (z) an Excluded Asset for any purposes hereunder. Purchase Price adjustments calculated in the same manner as the adjustments in Section 2.3(a) with respect to the affected Property (or portion thereof), if any, shall be calculated from the period from and after the Effective Date to the date of the conveyance, and the net amount of such adjustment, if positive, shall be paid by Purchaser to Seller, and, if negative, by Seller to Purchaser.

3.13 Preferential Purchase Rights.

(a) Any preferential purchase right must be exercised subject to all terms and conditions set forth in this Agreement, including the successful Closing of this Agreement pursuant to Section 8.1 on the dates set forth herein. The consideration payable under this Agreement for any particular Asset for purposes of preferential purchase right notices shall be the Allocated Value for such Asset, adjusted as set forth herein.

(b) If any preferential right to purchase any Asset is validly exercised prior to Closing, (i) the affected Asset (or portion(s) thereof) shall not be conveyed to Purchaser at Closing, (ii) the Unadjusted Purchase Price shall be reduced by the Allocated Value of such Asset (or portion(s) thereof), (iii) such Asset (or portion(s) thereof) shall be deemed to be deleted from the applicable Exhibits attached hereto and added to Schedule 1.3 attached hereto, (iv) such Asset shall constitute an Excluded Asset for all purposes hereunder, and (v) Seller shall convey the affected Asset (or portion(s) thereof) to the preferential right holder on the terms and provisions set out in the applicable preferential right provision and shall be entitled to the consideration paid by such holder.

(c) Should a third Person 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 has not yet expired by Closing, then (i) such Assets (or portions thereof) shall not be conveyed to Purchaser at Closing, (ii) the Unadjusted Purchase Price shall be reduced by the Allocated Value of each such Asset (or portion thereof subject to such preferential purchase right); (iii) each such affected Asset (or portion thereof) shall be subject to the remainder of this Section 3.13(c) and Section 3.13(d), and (iv) Seller shall continue to use commercially reasonable efforts (without the obligation to make any payments or undertake any obligations for the benefit of the holders of such preferential rights to purchase) to obtain the waiver of the preferential purchase right and shall continue to be responsible for the compliance therewith. Should the holder of the preferential purchase right validly exercise the same after Closing, (A) such affected Asset shall be deemed to be deleted from the applicable Exhibits attached hereto and added to Schedule 1.3 attached hereto, (B) such Asset (or portion thereof) shall constitute an Excluded Asset for all purposes hereunder, and (C) Seller shall convey the affected Asset (or portion thereof) to the preferential right holder on the terms and provisions set out in the applicable preferential right provision and Seller shall be entitled to the consideration paid by such holder.

-35-

(d) In the event that, after Closing, a preferential purchase right with respect to an Asset (or portion thereof) not conveyed to Purchaser at Closing pursuant to Section 3.13(c) is waived in writing or the time for exercise of such right has expired pursuant to its terms without exercise by the holder thereof, (i) Purchaser shall purchase the affected Asset (or portion thereof) on the terms set forth in this Agreement at a delayed closing which shall occur within ten (10) Business Days following the date on which Seller obtains such waiver, or the time period for exercising the applicable preferential right has expired (which date shall, with respect to such Asset, or portion thereof, be considered to be the Closing Date with respect to such Asset (or applicable portion thereof)), (ii) 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 Asset (or portion thereof) at such delayed Closing; and (iii) Purchaser shall, simultaneously with the conveyance of the applicable Asset (or portion thereof), pay the amount of any previous deduction from the Unadjusted Purchase Price (subject to all other applicable adjustments with respect to such Asset (or portion thereof) under this Agreement) to Seller, and (iv) such Asset shall no longer be (A) deemed to be deleted from the Exhibits attached hereto, (B) added to Schedule 1.3 attached hereto or (C) an Excluded Asset for any purposes hereunder. Purchase Price adjustments calculated in the same manner as the adjustments in Section 2.3(a) with respect to the affected Asset (or portion thereof), if any, shall be calculated from the period from and after the Effective Date to the date of the conveyance, and the net amount of such adjustment, if positive, shall be paid by Purchaser to Seller, and, if negative, by Seller to Purchaser.

3.14 Limitations on Applicability. Purchaser’s right to allege Title Defects and Environmental Defects pursuant to this Article 3 shall terminate as of the Defect Claim Date and shall have no further force and effect thereafter, provided there shall be no termination of Purchaser’s or Seller’s rights under this Article 3 with respect to any Environmental Defect, Title Defect or Title Benefit claim properly reported on or before the Defect Claim Date.

(a) Subject to, and without limitation of, Seller’s right to indemnification pursuant to Article 11, and except for instances of Fraud, the representations and warranties of VTLE and NOG set forth in this Article 5 and the corresponding certification in the certificate to be delivered at Closing pursuant to Section 8.3(f) as to the accuracy as of the Closing Date of the representations and warranties of Purchaser set forth in this Article 5, (i) VTLE and NOG make no other representations or warranties, express or implied, and (ii) VTLE and NOG expressly disclaim all liability and responsibility for any representation, warranty, statement, or information made or communicated (orally or in writing) to Seller or any of its Affiliates, employees, agents, consultants, or other Representatives (including any opinion, information, projection, or advice that may have been provided to Seller by any officer, director, employee, agent, consultant, advisor or other Representative of Purchaser or any member of Purchaser Group).

(b) Inclusion of a matter on any of the Schedules which are referenced in this Article 5 (such Schedules, the “Purchaser Disclosure Schedules”) with respect to a representation or warranty that addresses matters having a Purchaser Material Adverse Effect shall not be deemed an indication that such matter does, or may, have a Purchaser Material Adverse Effect. The Purchaser Disclosure Schedules may include matters not required by the terms of the Agreement to be listed on the schedules, which additional matters are disclosed for purposes of information only, and inclusion of any such matter does not mean that all such matters are included. A matter scheduled on any of the Purchaser Disclosure Schedules as an exception for any representation and/or warranty shall be deemed to be an exception to all representations and/or warranties for which it is relevant, but only to the extent such relevance is reasonably apparent based on the face of the disclosure in which such matter is disclosed in the Purchaser Disclosure Schedules.

ARTICLE 6

COVENANTS OF THE PARTIES

6.1 Access. Upon execution of this Agreement until the Closing Date, subject to the limitations expressly set forth in this Agreement, Seller shall provide Purchaser and its Representatives reasonable access to the Assets operated by Seller or any of its Affiliates and access to and the right to copy, at Purchaser’s sole expense, the Records in Seller’s or any of its Affiliates’ possession or control for the purpose of conducting a confirmatory review of the Assets, but only to the extent that Seller may do so without (a) violating applicable Laws, (b) violating any obligations to any Third Party, (c) waiving any legal privilege of Seller, any of its Affiliates or its counselors, attorneys, accountants or consultants, and (d) to the extent that Seller has authority to grant such access without breaching any restriction binding on Seller. Such access by Purchaser shall be limited to Seller’s normal business hours, and Purchaser’s investigation shall be conducted in a manner that reasonably minimizes interference with the operation of the business of Seller and any applicable Third Party operator. In addition to, and without limitation of, the foregoing access rights of Purchaser, in the interest of facilitating Purchaser’s timely exercise of its rights under Section 3.1(a), within one (1) Business Day after the Execution Date, Seller shall make available to Purchaser and its Representatives via a virtual data room, fileshare or similar electronic medium, all or substantially all of Seller’s Records electronically available as of the Execution Date relating to Seller’s title to the Assets currently used by Seller in connection with the ownership and operation of the Assets (“Electronic Title Records”); provided, however, if Seller fails to grant such access to all or substantially all of such Electronic Title Records within such one (1) Business Days period, then the Defect Claim Date, the Target Closing Date, the Outside Date and the Extended Outside Date shall each be automatically tolled day-for-day until such time as Seller has provided Purchaser with such access to the Electronic Title Records; provided, further, that if, prior to the date that is ten (10) Business Days following the Execution Date, Purchaser has not provided to Seller a written notice that Purchaser has not received access to the Electronic Title Records, then the Defect Claim Date, the Target Closing Date, the Outside Date and the Extended Outside Date shall not be tolled as provided in the immediately preceding proviso. Subject to the terms of this Agreement, all investigations and due diligence conducted by Purchaser or any of Purchaser’s Representatives shall be conducted at Purchaser’s sole cost, risk and expense and any conclusions made from any examination done by Purchaser or any of Purchaser’s Representatives shall result from Purchaser’s own independent review and judgment. Seller shall use commercially reasonable efforts (but without the obligation to incur any out-of-pocket costs, expenses, or the obligation to undertake any liability or other obligations to or by Seller) to (i) obtain permission for Purchaser to gain access from any Third Party to whom Seller owes obligations including to gain access to Third Party operated Assets to inspect the condition of the same; provided, however, that Seller shall have no liability to Purchaser (or otherwise

-48-

be in breach of this agreement) for failure to obtain such operator’s permission, (ii) obtain a waiver of confidentiality obligations owed to any Third Parties or establish any necessary confidential relationships with Third Parties reasonably required to allow Purchaser to view and access the Records, and (iii) grant any access to which Seller has the authority to grant without breaching any restriction binding on Seller. Seller or its designee shall have the right to accompany Purchaser and its Representatives whenever they are on site on the Assets.

6.2 Press Releases. Until the Closing, neither Seller nor Purchaser, nor any Affiliate thereof, shall make any press release or public disclosure or statement regarding the existence of this Agreement, the contents hereof, or the transactions contemplated hereby without the prior written consent of Purchaser (in the case of announcements by Seller or its Affiliates) or Seller (in the case of announcements by Purchaser or its Affiliates), which consent shall not be unreasonably withheld or delayed; provided, however, the foregoing shall not restrict disclosures by Purchaser or Seller (i) with respect to a press release or disclosure by Purchaser, after Purchaser has, if and to the extent reasonably practicable, provided Seller with the opportunity to review and provide comments to any such proposed press release or disclosure (which comments shall, if and to the extent reasonably practicable, be considered in good faith by Purchaser), (ii) to the extent that such disclosures are required by applicable securities or other Laws or the applicable rules of any stock exchange having jurisdiction over the disclosing Party or its Affiliates, (iii) to Governmental Authorities and Third Parties holding preferential rights to purchase, rights of consent or other rights that may be applicable to the transactions contemplated by this Agreement, as reasonably necessary to provide notices, seek waivers, amendments or terminations of such rights, or seek such consents, or (iv) to such Party’s investors and members, and current or prospective financing sources, including Seller’s Affiliates’ investors and limited partners, and to prospective investors or other Persons as part of fundraising or marketing activities undertaken by Seller’s Affiliates or Vortus and its Affiliates provided such disclosures are made to Persons subject to an obligation of confidentiality with respect to such information. Seller, VTLE and NOG shall each be liable for the compliance of its respective Affiliates, and Seller shall be responsible for the compliance by Vortus and its Affiliates, with the terms of this Section 6.2. Notwithstanding anything to the contrary hereunder, no Party shall disclose, make public or include in any public filing the Exhibits or Schedules attached to this Agreement, or any information thereunder, without the express prior written consent of the other Party, which may be denied in such Party’s sole discretion. The Parties agree that neither Purchaser nor Seller may have an adequate remedy at law if any of the foregoing Persons violate (or threaten to violate) any of the terms of this Section 6.2. In such event, Purchaser or Seller, as applicable, shall have the right, in addition to any other it may have, to seek injunctive relief to restrain any breach or threatened breach of the terms of this Section 6.2.

Any approval delivered by one of the individuals listed on Schedule 6.3 – Part B shall constitute an approval on behalf of Purchaser, regardless whether such individual is a VTLE or NOG personnel member. Purchaser’s approval of any action restricted by this Section 6.3 shall not be unreasonably withheld or delayed (except as expressly provided in the introduction to this Section 6.3) and shall be considered granted in full within five (5) Business Days (unless a shorter time, not to be less than 48 hours, is reasonably required by the circumstances and such shorter time is specified in Seller’s notice) of delivery of Seller’s notice to Purchaser requesting such consent unless Purchaser notifies Seller to the contrary during that period.

Purchaser acknowledges that Seller owns undivided interests in the Assets and may not be the operator of all of the Assets, and Purchaser agrees that the acts or omissions of Third Parties (including the applicable operators of the Assets) who are not Affiliates of Seller shall not constitute a violation of the provisions of this Section 6.3, nor shall any action required by a vote of Working Interest owners constitute such a violation so long as Seller and its Affiliates have voted their respective interests or exercised any applicable rights under any applicable Contracts in a manner consistent with the provisions of this Section 6.3.

ANY INDEMNITY PROVIDED BY PURCHASER PURSUANT TO THIS SECTION 6.4 SHALL BE MADE BY VTLE AND NOG ON A SEVERAL, AND NOT JOINT AND SEVERAL, BASIS IN ACCORDANCE WITH THEIR RESPECTIVE PURCHASER PRO RATA SHARES. SUBJECT TO, AND WITHOUT LIMITATION OF PURCHASER’S RIGHTS AND REMEDIES UNDER THE R&W INSURANCE POLICY FOR BREACHES OF, OR INACCURACIES IN, SELLER’S REPRESENTATIONS AND WARRANTIES SET FORTH IN ARTICLE 4 OR SET FORTH IN THE CORRESPONDING CERTIFICATION IN THE CERTIFICATE TO BE DELIVERED AT CLOSING PURSUANT TO SECTION 8.2(e) AS TO THE ACCURACY AS OF THE CLOSING DATE OF THE REPRESENTATIONS AND WARRANTIES OF SELLER SET FORTH IN ARTICLE 4, AND EXCEPT FOR INSTANCES OF FRAUD (AS DEFINED HEREIN), PURCHASER RECOGNIZES AND AGREES THAT ALL MATERIALS, DOCUMENTS, SAMPLES, REPORTS, AND OTHER INFORMATION OF ANY TYPE AND NATURE MADE AVAILABLE TO IT, ITS AFFILIATES OR REPRESENTATIVES, IN CONNECTION WITH THE TRANSACTION CONTEMPLATED HEREBY, WHETHER MADE AVAILABLE PURSUANT TO ARTICLE 6 OR OTHERWISE, ARE MADE AVAILABLE TO IT AS AN ACCOMMODATION, AND WITHOUT REPRESENTATION OR WARRANTY OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, AS TO THE ACCURACY AND COMPLETENESS OF SUCH MATERIALS, DOCUMENTS, SAMPLES, REPORTS, AND OTHER INFORMATION, AND NO WARRANTY OF ANY KIND IS MADE BY SELLER AS TO SUCH INFORMATION SUPPLIED TO PURCHASER OR ITS AFFILIATES OR REPRESENTATIVES AND PURCHASER EXPRESSLY AGREES THAT, SUBJECT TO THE FOREGOING LIMITATIONS, ANY RELIANCE UPON SUCH INFORMATION, OR CONCLUSIONS DRAWN THEREFROM, SHALL BE THE RESULT OF ITS OWN INDEPENDENT REVIEW AND JUDGMENT.

6.5 Governmental Reviews.

(a) Seller and Purchaser shall each in a timely manner make (or cause their applicable Affiliates to make) (i) all required filings, and prepare applications to, and conduct negotiations with, each Governmental Authority as to which such filings, applications or negotiations are necessary or appropriate in the consummation of the transactions contemplated hereby, and (ii) provide such information as the other may reasonably request in order to make such filings, prepare such applications and conduct such negotiations. Each Party shall cooperate with and use all reasonable efforts to assist the other with respect to such filings, applications and negotiations. Purchaser shall bear the cost of all filing or application fees payable to any Governmental Authority with respect to the transactions contemplated by this Agreement, regardless of whether Purchaser, Seller, or any Affiliate of any of them is required to make the payment.

(b) Without limitation of Section 12.4, on or before the Closing Date, Purchaser shall post or obtain such Credit Support that is set forth on Schedule 4.18 as is required by the applicable Governmental Authority or Contract counterparty for Purchaser’s ownership of the Assets and to replace or cancel the existing Credit Support, and shall provide Seller with evidence of the same.

(c) Promptly after Closing, Purchaser (with the assistance of Seller, subject to Section 12.3) shall make all filings with any applicable Governmental Authority (including in each applicable county), as may be required to properly assign and transfer the Assets from Seller to Purchaser.

(d) In furtherance of Section 6.5(a), as soon as practicable following the Execution Date, but in no event later than ten (10) Business Days following the Execution Date, Seller and VTLE shall make or cause to be made such filings as may be required by the HSR Act with respect to the transactions contemplated by the Transaction Agreements (the “HSR Filing”), which HSR Filing shall include a request for early termination of any applicable waiting period. Thereafter, Seller and VTLE shall use their respective reasonable best efforts to respond

-52-

as promptly as practicable to all requests for reports or other documents required or requested by any relevant Governmental Authority pursuant to the HSR Act or any other Antitrust Law or otherwise including requests for additional information concerning such transactions, so that the waiting period specified in the HSR Act will expire or be terminated as soon as reasonably possible after the Execution Date, but in no event later than the Outside Date. The Parties will advise each other promptly of any material communication from any Governmental Authority, and of Seller and VTLE shall cause their respective counsel to furnish each other Party such necessary information and reasonable assistance as such other Party may reasonably request in connection with Seller and VTLE’s respective preparation of necessary filings or submissions under the provisions of the HSR Act. Each Party shall cause their counsel to provide prompt notification to the other Party when it becomes aware that any consent or approval referred to in this Section 6.5(d) is obtained, taken, made, given or denied, as applicable. Each Party shall promptly inform each other Party, and if in writing, furnish each other Party with copies of (or, in the case of oral communications, provide a summary of) any substantive communication from any Governmental Authority, and permit each other Party to review and discuss in advance, and consider in good faith the views of each other Party in connection with, any proposed substantive written or oral communication, correspondence, or submission to a Governmental Authority. No Party shall participate in any meeting or substantive discussion with any Governmental Authority in respect of any such HSR Filings or related investigations or other inquiries unless, to the extent practicable, it consults with the other Parties in advance and, to the extent practicable and permitted by such Governmental Authority, gives the other Parties the opportunity to attend and participate in such meeting. VTLE shall pay the statutory filing fee associated with filings under the HSR Act. Each Party may, as each deems advisable and necessary, reasonably designate any competitively sensitive information provided to another Party under this Section 6.5(d) as “outside counsel only,” and may also redact materials provided pursuant to this Section 6.5(d) (i) as necessary to comply with contractual obligations; and (ii) as necessary to protect privileged attorney-client communications or attorney work product. VTLE agrees to use reasonable best efforts to have the applicable HSR Act waiting period expire or be terminated on or before the Outside Date hereunder and, if necessary, to contest and resist, any action, including legislative, administrative or judicial action, and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order (whether temporary, preliminary or permanent) of any Governmental Authority that is in effect and that restricts, prevents or prohibits the consummation of the transactions contemplated by the Transaction Agreements. Notwithstanding anything to the contrary set forth in this Agreement, the obligations of VTLE under this Section 6.5 shall not include VTLE committing to: (i) sell, divest, or otherwise convey particular assets, categories, portions or parts of assets or businesses of VTLE or its Affiliates; (ii) agree to sell, divest, or otherwise convey any particular asset, category, portion or part of an asset or business to be acquired by it contemporaneously with or subsequent to the Closing; (iii) permit the Seller to sell, divest, or otherwise convey any of the particular assets, categories, portions or parts of assets or business of the Seller prior to the Closing; (iv) license, hold separate or enter into similar arrangements with respect to its respective assets or the assets of the Seller or conduct of business arrangements or terminate any and all existing relationships and contractual rights and obligations, and (v) obtain prior approval or other approval from a Governmental Authority, or submit a notification or otherwise notify any Governmental Authority, prior to consummating any future transaction (other than the transactions contemplated by this Agreement) as a condition to obtaining any and all expirations of waiting periods under the HSR Act or other Antitrust Laws or consents from any Governmental Authority necessary to consummate the transactions contemplated hereby.

6.6 Further Assurances. After Closing, Seller and Purchaser each agrees to take such further actions and to execute, acknowledge and deliver all such further documents as are reasonably requested by the other for carrying out the purposes of this Agreement or of any document delivered pursuant to this Agreement.

6.7 R&W Insurance Policy. Purchaser has obtained and conditionally bound the R&W Insurance Policy. Following the Execution Date, Purchaser shall maintain the binder agreement for the R&W Insurance Policy in full force and effect and satisfy the conditions set forth therein to cause the R&W Insurance Policy to be issued at the Closing on terms and in the form set forth therein, and a true and correct copy of the R&W Insurance Policy shall be provided to the Seller promptly after receipt thereof by Purchaser. The R&W Insurance Policy shall expressly provide and, if issued, shall provide that (a) the insurer(s) issuing such policy have waived or otherwise shall not pursue any subrogation, contribution or other rights against Seller or any of its Affiliates and/or any of their respective Representatives, except in the case of Fraud by Seller (it being understood and agreed that the Fraud of any Person shall not be imputed to any other Person), (b) Purchaser shall not (and shall cause its Affiliates not to) amend, modify, or otherwise change, terminate, or waive any provision of the R&W Insurance Policy in a manner adverse to Seller, any of its Affiliates or any of their respective Representatives, including any rights of the insurer to subrogate or seek recovery from Seller, any of its Affiliates or any of their respective Representatives, and (c) Seller, its Affiliates and

-53-

the Representatives of any of the foregoing are express third-party beneficiaries under the R&W Insurance Policy with respect to the matters described in this sentence. From and after the Execution Date, without the prior written consent of Seller, Purchaser shall not (and shall cause its Affiliates not to) grant any right of subrogation, contribution or other right or otherwise amend, modify, terminate or waive any term or condition of the R&W Insurance Policy in a manner inconsistent with the immediately preceding sentence. Seller agrees to reasonably cooperate with and take all commercially reasonable actions requested by Purchaser to provide information customarily reviewed or requested by insurers, underwriters and their representatives to assist Purchaser with issuing and fully binding the R&W Insurance Policy on or prior to the Closing Date. Prior to or concurrently with the Closing, all costs and expenses related to obtaining the R&W Insurance Policy, including the total premium, underwriting costs, taxes, brokerage commission, and other fees and expenses of such policy, shall be promptly and fully paid by Purchaser. Notwithstanding the foregoing, for the avoidance of doubt, the Parties acknowledge and agree that the obtaining of the R&W Insurance Policy is not a condition to the Closing, and Purchaser shall remain obligated, subject only to the satisfaction or waiver of the conditions set forth in Section 7.2, to consummate the transactions contemplated by this Agreement even if coverage under the R&W Insurance Policy binder lapses for any reason or if Purchaser fails to meet any conditions set forth in the R&W Insurance Policy binder or otherwise fails to obtain assurances that the R&W Insurance Policy will be issued on terms and in the form set forth in the R&W Insurance Policy binder following Closing.

6.8 Operatorship. As soon as reasonably practicable following Closing, Seller will (and will cause its applicable Affiliates to) send out notifications of its resignation as operator under any Contracts, effective as of the Closing Date, for all Properties that Seller (or any Affiliate of Seller) currently operates and transfers to Purchaser pursuant to this Agreement. Seller makes no representation and/or warranty to Purchaser as to the transferability or assignability of operatorship of such Properties. Seller agrees, however, that, as to the Assets it or any Affiliate of it operates, it shall use its commercially reasonable efforts to support VTLE’s effort to become successor operator of such Properties effective as of Closing and to designate, to the extent legally possible and permitted under any applicable joint operating agreement or other agreement, VTLE as successor operator of such Properties effective as of the Closing. Purchaser acknowledges that the rights and obligations associated with such Properties are governed by applicable agreements and that operatorship will be determined by the terms of those agreements. Notwithstanding anything to the contrary contained in this Section 6.8, the Parties shall execute Texas Railroad Commission Form P-4s for all Wells currently operated by Seller or its Affiliates, naming VTLE (or its designated Affiliate) as operator of such Wells with the Texas Railroad Commission at Closing as provided in Section 8.2(i).

6.9 Financial Information.

(a) Seller shall use:

(i) upon reasonable request by Purchaser, commercially reasonable efforts to cause the external audit firm that audits the Audited Seller Financial Statements (the “Audit Firm”) to cooperate with Purchaser and its Representatives to cause the Audited Seller Financial Statements to comply with Regulation S-X promulgated by the SEC (“Regulation S-X”) and other rules and regulations of the SEC with respect to reporting obligations of Purchaser and its Affiliates under the Exchange Act or any registration of securities under the Securities Act of 1933, as amended (the “Securities Act”); provided, however, notwithstanding anything to the contrary in this Agreement, none of Seller, its Affiliates or their respective representatives shall be responsible for the preparation of any pro forma financial information, which shall be prepared solely by Purchaser; provided, further, that, upon reasonable request by Purchaser, Seller shall use commercially reasonable efforts to provide or cause to be provided information not included in the Audited Seller Financial Statements that may be necessary for the preparation by Purchaser of any pro forma financial information;

-54-

for interim financial statements, and (D) upon reasonable request by Purchaser, cause the Audit Firm to cooperate with Purchaser and its Representatives to cause the June 30 Seller Financial Statements to comply with Regulation S-X and other rules and regulations of the SEC with respect to reporting obligations of Purchaser and its Affiliates under the Exchange Act or any registration of securities under the Securities Act; and

(iii) commercially reasonable efforts to, and shall use its commercially reasonable efforts to cause its Affiliates and their respective partners, members, shareholders, owners, officers, directors, managers, employees, agents and representatives, on a commercially reasonable basis to provide, in each case at Purchaser’s sole cost and expense, such assistance as is reasonably requested by Purchaser in connection with any arrangement, marketing, syndication and consummation of any financing that may be arranged by Purchaser to the extent reasonably deemed necessary or advisable by Purchaser to fund any portion of the Purchase Price (the “Financing”); provided that such requested assistance does not unreasonably interfere with operations of Seller or its Affiliates or its or their respective assets and that any information requested by Purchaser is reasonably available to Seller or any of its Affiliates or its or their Representatives.

(b) At either VTLE’s or NOG’s reasonable request, after the date of this Agreement for up to eighteen (18) months after the Closing Date (the “Records Period”), Seller agrees to use commercially reasonable efforts to make available to Purchaser and its Affiliates and their Representatives any and all Records to the extent in Seller’s or its Affiliates’ possession or control and to which Seller and its Affiliates’ personnel have reasonable access, in each case as reasonably required by Purchaser, its Affiliates and their Representatives in order to prepare financial statements in connection with Purchaser’s or its Affiliates’ debt or equity securities offerings or filings, if any, that are required by the SEC, under securities Laws applicable to Purchaser and its Affiliates, or financial statements meeting the requirements of Regulation S-X in connection with the transaction contemplated by this Agreement (the “Purchaser Financial Statements”).

(c) During the Records Period, Seller shall use commercially reasonable efforts to cause its accountants, consultants, reserve engineers, agents and other Representatives to, reasonably cooperate with VTLE and NOG and their respective Representatives in connection with the preparation by VTLE and/or NOG, as applicable, of the Purchaser Financial Statements that are required to be included in any filing by such Purchaser or its Affiliates with the SEC, or customarily included in offering documentation for debt or equity securities offerings, including to use their commercially reasonable efforts to cause the Audit Firm and the Reserve Engineer to (i) provide its consent to be named as an expert in (A) any filings that may be made by Purchaser under the Securities Act or required by the SEC under securities laws applicable to Purchaser or any report required to be filed by Purchaser under the Exchange Act in connection with the transactions contemplated by this Agreement or in connection with the Financing or (B) any prospectus or offering memorandum or (ii) to provide customary “comfort letters” to any underwriter or initial purchaser in connection with any debt or equity securities offering during the Records Period. If reasonably requested, Seller shall use commercially reasonable efforts to execute and deliver, or shall use commercially reasonable efforts to cause its Affiliates to execute and deliver, to the Audit Firm such representation letters, in form and substance customary for representation letters provided to external audit firms by management of the company whose financial statements are the subject of an audit, as may be reasonably requested by the Audit Firm, with respect to the Purchaser Financial Statements, including, as requested, representations regarding internal accounting controls and disclosure controls.

(d) In no event shall Seller or any of its Affiliates or Representatives be required to bear any cost or expense or pay any fee (other than reasonable out-of-pocket costs and expenses for which they are promptly reimbursed or indemnified) in connection with any action taken pursuant to this Section 6.9(a) through (c); provided, however, that the Parties agree that Seller, on the one hand, shall bear one-half, and Purchaser, on the other hand, shall bear one-half, of all costs and expenses incurred after the Execution Date associated with the preparation of the Audited Seller Financial Statements and the June 30 Seller Financial Statements pursuant to Section 6.9(a)(ii); provided, further that, Purchaser’s responsibility for such costs and expenses shall not exceed Two Hundred Fifty Thousand Dollars ($250,000). VTLE and NOG shall each be responsible their respective Purchaser Pro Rata Share of all fees and expenses related to the actions contemplated by this Section 6.9(a) through (c), including the compensation of any contractor or advisor of Seller or any of its Affiliates or Representatives.

-55-

Seller for all reasonable and documented out-of-pocket costs and expenses (including reasonable and documented compensation or other fees of any contractor or advisor of Seller or any of its Affiliates or Representatives) incurred in connection with the cooperation of Seller contemplated by this Section 6.9. Further, VTLE and NOG shall each, on a several, and not joint and several, basis, in accordance with their respective Purchaser Pro Rata Shares, indemnify and hold harmless the Seller Group from and against any and all claims, losses or Damages actually incurred or suffered by them in connection with the obligations of Seller and its Affiliates and Representatives under Section 6.9(a) through (c) (other than to the extent resulting from the gross negligence, bad faith or willful misconduct of Seller or any of its Affiliates or Representatives as determined in a final, non-appealable judgment of a court of competent jurisdiction).

(e) Notwithstanding anything to the contrary, the access to be provided to Purchaser and its Affiliates and their respective Representatives pursuant to this Section 6.9 shall not interfere with Seller’s or any of its Affiliates’ ability to prepare their own financial statements or Seller’s regular conduct of business and shall be made available during Seller’s normal business hours, unless reasonably requested otherwise by Purchaser. Such cooperation shall not require Seller to take any action that Seller reasonably believes could result in a violation of applicable Laws or the waiver of any legal or other applicable privilege.

(f) Nothing contained in this Section 6.9 shall require any such consent, cooperation or assistance to the extent that it would (i) require Seller, its Affiliates or any of their respective Representatives to pay any commitment or other fees, reimburse any expenses or otherwise incur any liabilities (other than the payment of reasonable out-of-pocket costs related to such cooperation which shall be promptly reimbursed by Purchaser on demand as set forth in Section 6.9(d)) or give any indemnities, (ii) unreasonably interfere with the ongoing business or operations of Seller or its Affiliates, (iii) result in any conflict with this Agreement or Seller’s or its Affiliates’ organizational documents or applicable Law, (iv) reasonably be expected to result in a violation of applicable Law on the part of Seller or any of its Affiliates or Representatives, or (v) provide access to or disclose information that Seller reasonably determines could jeopardize any attorney-client privilege of Seller or any of its Affiliates. Purchaser shall indemnify and hold harmless the Seller Group from and against any and all Damages suffered or incurred in connection with any Financing or any assistance or activities provided in connection therewith.

(g) Notwithstanding anything to the contrary herein, Seller shall not be deemed to be in breach of the covenants set forth in this Section 6.9 so long as it has acted in a good faith commercially reasonable manner to comply with the cooperation and assistance set forth herein. Purchaser acknowledges and agrees that Closing is not conditioned on Purchaser or its Affiliates obtaining any financing.

6.10 Employee Matters. With respect to employee matters, the Parties agree to the provisions of Exhibit E.

6.11 Further Actions. Subject to the terms of this Agreement, and without limitation of each Party’s respective rights and remedies under this Agreement, each Party shall use commercially reasonable efforts to take such actions as may be necessary to consummate the transactions contemplated by this Agreement.

6.12 Notification of Breaches. Without limiting the Seller Group’s rights to indemnification or to assert its rights to seek indemnification pursuant to Article 11 until the Closing,

(a) Each of VTLE and NOG shall notify Seller promptly after such Purchaser obtains knowledge that any representation or warranty of Seller contained in this Agreement is untrue in any material respect or will be untrue in any material respect as of the Closing Date or that any covenant or agreement to be performed or observed by Seller prior to or on the Closing Date has not been so performed or observed in any material respect.

(b) Seller shall notify Purchaser promptly after Seller obtains knowledge that any representation or warranty of Purchaser contained in this Agreement is untrue in any material respect or will be untrue in any material respect as of the Closing Date or that any covenant or agreement to be performed or observed by Purchaser prior to or on the Closing Date has not been so performed or observed in any material respect.

(c) If any Party has notice that (i) any of the other Parties’ representations or warranties are untrue or shall become untrue in any material respect between the date hereof and the Closing Date, or (ii) any of the other Parties’ covenants or agreements to be performed or observed prior to or on the Closing Date shall not have been so performed or observed in any material respect, but, in each case, if such breach of representation, warranty, covenant, or agreement shall (if curable) actually be fully cured on or before the Closing, then such breach shall be considered not to have occurred for all purposes of this Agreement.

6.13 Seller Post-Closing Cash. If the Closing occurs, Seller shall with respect to Seller’s obligations related to any adjustments or payments owed to Purchaser pursuant to Section 8.4, for the period commencing on the Closing Date and ending on the date on which the Final Settlement Statement is resolved pursuant to Section 8.4 (the “Support Expiration Date”), maintain at least Fifteen Million Dollars ($15,000,000) of unrestricted cash on its balance sheet to support the obligations of Seller (following Closing) to the extent relating to any adjustments or payments owed to Purchaser pursuant to Section 8.4.

Seller shall supply to Purchaser reasonable documentation in the possession or control of Seller and its Affiliates to support the items for which adjustments are proposed or made in the Preliminary Settlement Statement delivered by Seller and a reasonably detailed explanation of any such adjustments and the reasons therefor. Within three (3) Business Days after receipt of Seller’s draft Preliminary Settlement Statement, Purchaser may deliver to Seller a written report containing all changes that Purchaser proposes to be made to the Preliminary Settlement Statement, if any, together with a brief explanation of any such changes. The Preliminary Settlement Statement, as agreed upon by the Parties, will be used to adjust the Unadjusted Purchase Price at Closing; provided that if the Parties cannot agree on all adjustments set forth in the Preliminary Settlement Statement prior to the Closing, then any adjustments as set forth in the Preliminary Settlement Statement as presented by Seller (with any amendments or modifications thereto that were so agreed between the Parties) will be used to adjust the Unadjusted Purchase Price at Closing. For purposes of clarity, Purchaser’s failure to propose any changes to the Preliminary Settlement Statement and/or Purchaser’s agreement to all or any portion of the Preliminary Settlement Statement proposed by Seller shall not, and shall not be deemed or construed to, prejudice any of Purchaser’s rights hereunder (including, for purposes of clarity, Purchaser’s right to dispute any adjustment or amount set forth in the Preliminary Settlement Statement in connection with the final calculation and determination of the Purchase Price pursuant to Section 8.4(b) and/or Section 8.4(c), as applicable).

-60-

(b) As soon as reasonably practicable after the Closing but not later than the ninetieth (90th) day following the Closing Date, Seller shall prepare and deliver to Purchaser a draft statement setting forth the final calculation of the Purchase Price (the “Final Settlement Statement”) and showing the calculation of each adjustment under Section 2.3, based on the most recent actual figures available for each adjustment. Seller shall make such reasonable documentation as is in Seller’s or any of its Affiliates’ possession or control available to support the final figures set forth in the Final Settlement Statement. As soon as reasonably practicable, but not later than the thirtieth (30th) day following receipt of such Final Settlement Statement from Seller (as such time period may be extended as described below, the “Purchaser Comment Deadline”), Purchaser may deliver to Seller a written report containing any changes that Purchaser proposes be made to such Final Settlement Statement. Seller may deliver a written report to Purchaser on or prior to the Purchaser Comment Deadline reflecting any changes that Seller proposes to be made to the Final Settlement Statement as a result of additional information received after the Final Settlement Statement was first prepared and delivered to Purchaser hereunder (and if any such written report is delivered by Seller to Purchaser on or after the date that is five (5) Business Days before the Purchaser Comment Deadline, then the Purchaser Comment Deadline will be automatically extended for five (5) Business Days). If Purchaser does not deliver such report to Seller on or before the Purchaser Comment Deadline, Purchaser shall be deemed to have agreed with Seller’s Final Settlement Statement, and such Final Settlement Statement shall become final and binding upon the Parties.

(c) The Parties shall undertake to agree on the Final Settlement Statement of the Purchase Price no later than ninety (90) days after the delivery to Purchaser of Seller’s initial Final Settlement Statement. In the event that the Parties cannot reach agreement on the final Purchase Price within such period of time, any Party may refer the items of adjustment which are in dispute to, the Houston, Texas office of KPMG, or, if such firm is not able or willing to serve, a nationally-recognized independent accounting firm or consulting firm mutually acceptable to both Purchaser and Seller (the “Accounting Arbitrator”), for review and final determination by arbitration. If Purchaser and Seller have not agreed upon a mutually acceptable alternate Person to serve as Accounting Arbitrator within ten (10) Business Days of receiving notice of KPMG’s unavailability, Seller shall, within ten (10) Business Days after the end of such initial ten (10) Business Day period, formally apply to the Houston, Texas office of the American Arbitration Association to choose the Accounting Arbitrator. The Accounting Arbitrator shall conduct the arbitration proceedings in Houston, Texas in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section 8.4(c). The Accounting Arbitrator’s determination shall be made within forty-five (45) days after submission of the matters in dispute and shall be final and binding on all Parties, without right of appeal. In determining the proper amount of any adjustment to the Purchase Price, the Accounting Arbitrator shall be bound by the terms of Article 2 and may not increase the Purchase Price more than the increase proposed by Seller nor decrease the Purchase Price more than the decrease proposed by Purchaser, as applicable. The Accounting Arbitrator shall act as an expert for the limited purpose of determining the specific disputed aspects of Purchase Price adjustments submitted by any Party and may not award damages, interest (except as expressly provided for in this Section 8.4(c)) or penalties to any Party with respect to any matter. Seller and Purchaser shall each bear their own legal and accounting fees and other costs of presenting its case to the Accounting Arbitrator. The fees, costs and expenses of the Accounting Arbitrator 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 Accounting Arbitrator bears to the amount actually contested by such Party with respect to all applicable disputed matters. Within ten (10) days after the earlier of (i) the Purchaser Comment Deadline without delivery by Purchaser to Seller of any written report with respect to the Final Settlement Statement under Section 8.4(b) or (ii) the date on which the Parties or the Accounting Arbitrator, as applicable, finally determine the Purchase Price, (x) Purchaser shall pay to Seller in cash the amount by which the Purchase Price (less the Deposit (together with all earnings, interest and income thereon), and the Defect Escrow Amount (if applicable)) exceeds the Closing Payment or (y) Seller shall pay to Purchaser in cash the amount by which the Closing Payment exceeds the final Purchase Price (less the Deposit (together with all earnings, interest and income thereon), and the Defect Escrow Amount (if applicable)), as applicable. Any amounts paid by or to Purchaser pursuant to this Section 8.4(c) shall be paid to or by VTLE and NOG in accordance with their respective Purchaser Pro Rata Shares.

(d) Purchaser shall use commercially reasonable efforts to assist Seller in preparation of the Final Settlement Statement under Section 8.4(b) by furnishing invoices, receipts, reasonable access to personnel, and such other assistance as may be reasonably requested by Seller to facilitate such process post-Closing (but in no event shall Purchaser be obligated to pay or incur any funds in connection with providing such assistance).

-61-

(e) All cash payments made or to be made under this Agreement to Seller shall be made by electronic transfer of immediately available funds to a bank account as may be specified by Seller in writing. All cash payments made or to be made hereunder to Purchaser shall be by electronic transfer of immediately available funds to the banks and accounts specified by Purchaser in writing.

ARTICLE 9

TAX MATTERS

9.1 Allocation of Asset Taxes.

(a) Solely for purposes of determining the adjustments to the Purchase Price with respect to Asset Taxes pursuant to Section 2.3 or Section 8.4 and any amounts payable by Seller to Purchaser pursuant to Section 9.2, Seller shall be allocated and bear all Asset Taxes attributable to (i) any Tax period ending prior to the Effective Date and (ii) the portion of any Straddle Period ending immediately prior to the Effective Date, provided, however, with respect to both clauses (i) and (ii), that Purchaser shall be allocated and bear Asset Taxes associated with the Hydrocarbons produced from, or attributable to, the Properties and sold during the period up to but excluding the Effective Date, if the amount earned from the sale is not received by Seller prior to the Cut-Off Date. Purchaser shall be allocated and bear all Asset Taxes attributable to (A) any Tax period beginning on or after the Effective Date and (B) the portion of any Straddle Period beginning on the Effective Date; provided, however, that Seller (not Purchaser) shall be allocated and bear the portion, if any, of any such Asset Taxes that consist of penalties, interest or additions to tax to the extent attributable to a breach by Seller of the representations set forth in Section 4.3.

(b) For purposes of determining the allocations described in Section 9.1(a), (i) Asset Taxes that are attributable to the severance or production of Hydrocarbons (other than such Asset Taxes described in clause (iii) below) shall be allocated to the period in which the severance or production giving rise to such Asset Taxes occurred, (ii) Asset Taxes that are imposed on a transactional basis (other than such Asset Taxes described in clause (i) or (iii)), 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 other 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 Date and the portion of such Straddle Period beginning on the Effective Date by prorating each such Asset Tax based on the number of days in the applicable Straddle Period that occur before the Effective Date, on the one hand, and the number of days in such Straddle Period that occur on or after the Effective Date, on the other hand. For purposes of clause (iii) of the preceding sentence, 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 determinable at the time an adjustment to the Purchase Price is to be made with respect to such Asset Tax pursuant to Section 2.3 or Section 8.4, Seller and Purchaser shall utilize the most recent information available in estimating the amount of such Asset Tax for purposes of such adjustment.

9.2 Tax Returns. After the Closing Date, Purchaser shall (i) file (or cause to be filed) all Tax Returns with respect to Asset Taxes that are required to be filed after the Closing Date that relate to any Tax period ending before the Effective Date or any Straddle Period on a basis consistent with past practice except to the extent otherwise required by Law; provided that Purchaser shall use its reasonable best efforts, taking into account that the due date for a Tax Return may be contemporaneous with the closing of a Tax period, to submit each such Tax Return to Seller for its review and comment reasonably in advance of the due date therefor, and Purchaser shall incorporate any reasonable comments received from Seller up to five (5) days prior to the due date therefor and timely file any such Tax Return, and (ii) pay (or cause to be paid) prior to delinquency, all Asset Taxes relating to any Tax period that ends before or includes the Effective Date that become due after the Closing Date. In the case of any Tax Return described in clause (i) required to be filed after the final determination of the Final Settlement Statement pursuant

-62-

to Section 2.3(i), that includes Asset Taxes that are allocable to Seller pursuant to Section 9.1(a), Purchaser shall deliver to Seller a statement that apportions the Asset Taxes shown on such Tax Return between Purchaser and Seller in accordance with Section 9.1(a). Such statement shall be accompanied by proof of Purchaser’s actual payment of such Asset Taxes. Within ten (10) Business Days of receipt of each such statement and proof of payment, Seller shall reimburse Purchaser for the portion of such Asset Taxes allocated to Seller in accordance with Section 9.1(a), except to the extent such Asset Taxes have been taken into account in the final determination of the Final Settlement Statement pursuant to Section 2.3(i). In each case, without Seller’s prior written consent (not to be unreasonably withheld, conditioned or delayed), neither Purchaser or any of its Affiliates shall (i) file, or cause to be filed, any amended Tax Return with respect to the Assets for any Tax period ending prior to the Effective Date or for any Straddle Period, (ii) make or change any Tax election for, or that has retroactive effect to, any Tax period ending prior to the Effective Date or for any Straddle Period, (iii) enter into any voluntary disclosure with any taxing authority with respect to Asset Taxes or related Tax Returns for a Tax period ending prior to the Effective Date or for any Straddle Period or (iv) extend or waive the statute of limitations with respect to Asset Taxes for any Tax period ending prior to the Effective Date or for any Straddle Period to the extent any of the actions described in clauses (i) – (iv) reasonably would be expected to increase the amount Taxes for which Seller is responsible pursuant to Section 9.1. The Parties agree that (A) this Section 9.2 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 (B) nothing within this Section 9.2 shall be interpreted as altering the manner in which Asset Taxes are allocated and economically borne by the Parties.

9.3 Transfer Taxes. To the extent that any Transfer Taxes are payable, Purchaser will be responsible for one hundred percent (100%) of all Transfer Taxes and shall prepare and file, or cause to be prepared and filed, all related Tax Returns. Purchaser and Seller shall agree, upon request, to cooperate in good faith to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed in connection with the transactions contemplated herein.

9.4 Cooperation on Tax Matters. 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 another Party’s request) 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 Tax period beginning before the Closing Date until the expiration of the statute of limitations of the respective Tax periods and to abide by all record retention agreements entered into with any Governmental Authority.

9.5 Tax Proceedings. Purchaser shall, within five (5) days of receipt, provide Seller with written notice of any inquiries, audits, examinations or proposed adjustments by any Governmental Authority, which relates to any Asset Taxes (x) for any Tax period ending prior to the Effective Date or (y) for any Straddle Period (each, a “Pre-Effective Date Tax Proceeding”). Seller shall have the option to control the conduct and resolution of any Pre-Effective Date Tax Proceeding that relates solely to a Tax period ending prior to the Effective Date for which Seller reasonably would be expected to have a material liability under this Agreement. Seller may exercise such option by providing written notice to Purchaser within fifteen (15) days of receiving written notice of any such Pre-Effective Date Tax Proceeding from Purchaser. If Seller elects to control a Pre-Effective Date Tax Proceeding, Seller shall (i) keep Purchaser informed of the progress of any such Pre-Effective Date Tax Proceeding, (ii) provide Purchaser with copies of material correspondence with respect to any such Tax Proceeding, (iii) permit Purchaser (or Purchaser’s counsel) to participate in meetings (including conference calls) with the applicable Governmental Authority with respect to any such Pre-Effective Date Tax Proceeding (at Purchaser’s cost), and (iv) not effect any settlement or compromise of any such Pre-Effective Date Tax Proceeding without the written consent of Purchaser, not to be unreasonably conditioned, delayed or withheld. Purchaser shall control any Pre-Effective Date Tax Proceeding that Seller does not elect to control and any Pre-Effective Date Tax Proceeding that relates to any Straddle Period; provided that Purchaser shall (I) keep Seller informed of the progress of any such Pre-Effective Date Tax Proceeding, (II) provide Seller with copies of material correspondence with respect to any such Pre-Effective Date Tax Proceeding, (III) permit Seller (or Seller’s counsel) to participate in meetings (including conference calls) with the applicable Governmental Authority with respect to any such Pre-Effective Date Tax Proceeding (at Seller’s cost), and (IV) not effect any settlement or compromise of any such Pre-Effective Date Tax Proceeding without the written consent of Seller, not to be unreasonably conditioned, delayed or withheld. In the event of a conflict between the provisions in this Section 9.5 and those in Section 11.4, this Section 9.5 shall control.

-63-

9.6 Allocation of Purchase Price. After the Closing, the Parties shall cooperate in good faith to allocate the Unadjusted Purchase Price, Assumed Obligations, and all other items constituting consideration for applicable Income Tax purposes (to the extent known) among the Assets in accordance with Section 1060 of the Code and the Treasury Regulations promulgated thereunder and in a manner consistent with Schedule 2.2 (the “Allocation”). If Seller and Purchaser reach an agreement with respect to the Allocation, Seller and Purchaser shall report, and cause their respective Affiliates to report, the transactions contemplated by this Agreement consistently with such agreed-upon Allocation on any Tax Return, including Internal Revenue Service Form 8594, as applicable, and will not assert, and will cause their respective Affiliates not to assert, in connection with any Tax audit or other proceeding with respect to Taxes, any asset values or other items inconsistently with such agreed-upon Allocation except with the agreement of the other Party or as required by applicable Law; provided, however, that nothing in this Agreement shall prevent Purchaser or Seller from settling any proposed deficiency or adjustment by any Governmental Authority based upon or arising out of the Allocation and neither Purchaser or Seller shall be required to litigate before any court any proposed deficiency or adjustment by any Governmental Authority challenging the Allocation. The Parties agree to promptly advise each other regarding the existence of any Tax audit, controversy or litigation related to the Allocation.

ARTICLE 10

TERMINATION

10.1 Termination. This Agreement may be terminated at any time prior to Closing:

(a) by the mutual prior written consent of Seller, VTLE and NOG;

(b) by either Seller, VTLE or NOG if the Closing has not occurred on or before September 30, 2024 (the “Outside Date”); provided, however, that if the applicable waiting period (and any extensions thereof) under the HSR Act have not expired or otherwise been terminated on or prior to such date, but all other conditions precedent to Closing set forth in Article 7 have been satisfied or waived (except for any such conditions that by their nature may only be satisfied at or in connection with the occurrence of Closing), then the Outside Date will be immediately and automatically extended without any further action by any of the Parties until October 25, 2024 (“Extended Outside Date”);

(c) by Seller, at Seller’s option, if any of the conditions set forth in Section 7.1 (other than Sections 7.1(c) or 7.1(d)) have not been satisfied by the Target Closing Date (except for those conditions that by their nature are to be satisfied at or in connection with the Closing and that would have been capable of being satisfied at or in connection with the Closing) and, following written notice thereof from Seller to Purchaser specifying the reason any such condition is unsatisfied (including any material breach by Purchaser of this Agreement), such condition remains unsatisfied for a period of twenty (20) days after Purchaser’s receipt of written notice thereof from Seller;

(d) by Purchaser, at Purchaser’s option, if any of the conditions set forth in Section 7.2 (other than Sections 7.2(c) or 7.2(d)) have not been satisfied by the Target Closing Date (except for those conditions that by their nature are to be satisfied at or in connection with the Closing and that would have been capable of being satisfied at or in connection with the Closing) and, following written notice thereof from Purchaser to Seller specifying the reason any such condition is unsatisfied (including any material breach by Seller of this Agreement), such condition remains unsatisfied for a period of twenty (20) days after Seller’s receipt of written notice thereof from Purchaser;

(g) by (A) Purchaser, if the condition set forth in Section 7.2(d) is not satisfied on or before the Target Closing Date or (B) by Seller, if the condition set forth in Section 7.1(d) is not satisfied on or before the Target Closing Date; provided that, if either Party notifies the other Party of its intention to terminate this Agreement pursuant to this Section 10.1(g), the non-terminating Party may, prior to giving effect to such termination, elect by written notice (an “Arbitration Notice”) to submit all unresolved disputes with respect to any Title Defects, Title Benefits, Title Defect Amounts, Title Benefit Amounts, Environmental Defects or Environmental Defect Amounts to expert arbitration in accordance with Section 3.10, as applicable, for the sole purpose of determining whether the condition in Section 7.2(d) or Section 7.1(d) has been satisfied. In such case, the Parties shall select a Title Arbitrator

-64-

or Environmental Arbitrator within five (5) Business Days of the delivery of the Arbitration Notice, each Party shall submit such Party’s position to the Title Arbitrator or Environmental Arbitrator, as applicable, within ten (10) Business Days of the delivery of an Arbitration Notice, and each Party shall instruct the Title Arbitrator or Environmental Arbitrator, as applicable, to deliver its determination of (1) the Environmental Defect Amount(s) attributable to all disputed Environmental Defects, (2) the Title Defect Amount(s) attributable to all disputed Title Defects and/or (3) the Title Benefit Amount(s) attributable to all disputed Title Benefits, as applicable, within twenty (20) days after the appointment of such Person. If an Arbitration Notice is delivered, no termination pursuant to this Section 10.1(g) shall be effective (and the Outside Date shall be tolled beginning on the date the Arbitration Notice is delivered to the Party seeking to terminate this Agreement pursuant to this Section 10.1(g)) until final resolution of such arbitration. Nothing herein shall prevent Purchaser from electing to waive or withdraw any asserted Title Defect or Environmental Defect at any time prior to termination of this Agreement;

provided, however, that, no Party shall be entitled to terminate this Agreement under Section 10.1(b), 10.1(c) 10.1(d) or 10.1(g) as applicable, if, at the time such Party would otherwise be entitled to exercise such right to terminate this Agreement, such Party: (A) is in breach of any of its representations or warranties set forth in this Agreement or (B) such Party has failed to perform or observe such Party’s covenants and agreements in this Agreement, in each case of (A) or (B), in a manner that causes any condition with respect to the other Party’s obligation to consummate the transactions contemplated by this Agreement set forth in Sections 7.1 or 7.2, as applicable, not to be satisfied, or (C) such Party fails to proceed with the consummation of the transactions contemplated by this Agreement once the applicable conditions in Section 7.1 (in the case of a failure by Seller) or Section 7.2 (in the case of a failure by Purchaser) have been satisfied or waived.

10.2 Effect of Termination. If this Agreement is terminated pursuant to Section 10.1, (a) this Agreement shall become void and of no further force or effect (except for the provisions of Article 1, this Article 10, Sections 2.1(b) 4.9, 4.26, 5.9, 5.10, 6.2, 6.4, 6.5, 11.4 (as it relates to claims under Section 6.4), 12.2, 12.3, 12.6, 12.7, 12.8, 12.9, 12.11, 12.13, 12.14, 12.15, 12.16, 12.17, and 12.18, all of which shall continue in full force and effect) and Seller shall be free immediately to enjoy all rights of ownership of the Assets and to sell, transfer, encumber or otherwise dispose of all or any portion of the Assets to any Person without any restriction under this Agreement and (b) there shall be no liability under this Agreement on the part of Purchaser or Seller or any of their respective Affiliates, partners, officers, owners, shareholders, members, officers, directors, managers, employees, agents or other Representatives except as expressly set forth in this Section 10.2, Section 10.3 and the Non-Disclosure Agreements, which Non-Disclosure Agreements shall survive any termination of this Agreement in accordance with its terms.

10.3 Distribution of Deposit and Remedies Upon Termination; Specific Performance.

(a) In the event that (i) all conditions precedent to the obligations of Seller set forth in Section 7.1 have been fulfilled, satisfied or waived in writing by Seller (except for those conditions that by their nature are to be satisfied by or on behalf of Purchaser at or in connection with Closing, all of which Purchaser stands ready, willing and able to satisfy, and other than the failure of any such conditions to Closing of Seller resulting from the breach or failure of any of Seller’s representations, warranties or covenants hereunder) and (ii) Purchaser is entitled to terminate this Agreement under Section 10.1(b) or 10.1(d) because the conditions precedent to the obligations of Purchaser set forth in Section 7.2 are not satisfied as of such time solely as a result of the breach or 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 the Purchaser Group shall be entitled, as its sole and exclusive remedy, to elect in writing, in Purchaser’s sole discretion, to either: (A) seek specific performance of this Agreement (without the necessity of posting bond or furnishing other security); provided that Purchaser’s ability to terminate this Agreement and seek recovery pursuant to clause (B) below shall not be limited if Purchaser causes any such action for specific performance to be dismissed prior to reaching a final, non-appealable decision; or (B) terminate this Agreement pursuant to Section 10.1(b) or 10.1(c), as applicable, in which case, Purchaser shall be entitled (1) to receive the entirety of the Deposit for the sole account and use of Purchaser and (2) to recover an amount equal to Purchaser’s reasonable and documented Third Party out-of-pocket costs and expenses paid or incurred in connection with negotiating the Transactions, up to an amount not to exceed Two Million Five Hundred Thousand Dollars ($2,500,000). In the case of clause (B) above, not later than two (2) Business Days following Purchaser’s election to terminate this Agreement, Seller, VTLE and NOG shall execute and deliver joint written instructions to the Escrow Agent to disburse the Deposit (together with all earnings, interest and income thereon) to VTLE and NOG in accordance with their respective Purchaser Pro Rata Shares.

-65-

(b) In the event that (i) all conditions precedent to the obligations of Purchaser set forth in Section 7.2 have been fulfilled, satisfied or waived in writing by Purchaser (except for those conditions that by their nature are to be satisfied by or on behalf of Seller at or in connection with Closing, all of which Seller stands ready, willing and able to satisfy) and (ii) Seller is entitled to terminate this Agreement under Section 10.1(b) or 10.1(c) because the conditions precedent to the obligations of Seller set forth in Section 7.1 are not satisfied as of such time solely as a result of the breach or failure 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 the Seller Group shall be entitled, as its sole and exclusive remedy, to terminate this Agreement pursuant to Section 10.1(b) or 10.1(c), as applicable, and receive the entirety of the Deposit for the sole account and use of Seller as liquidated damages hereunder without waiving or releasing the Purchaser’s obligations under the provisions that remain in effect following a termination pursuant to Section 10.2(a). Seller and Purchaser acknowledge and agree that (x) Seller’s actual damages upon the event of such a termination are difficult to ascertain with any certainty, (y) the Deposit is a fair and reasonable estimate by the Parties of such aggregate actual damages of Seller, and (z) such liquidated damages do not constitute a penalty. If Seller terminates this Agreement in accordance with clause B above, Seller, VTLE and NOG shall execute and deliver joint written instructions to the Escrow Agent to disburse the Deposit (together with all earnings, interest and income thereon) to Seller.

(c) In the event that Seller has elected to terminate this Agreement under Sections 10.1(e) or 10.1(f), Seller shall be entitled to receive from Purchaser an amount equal to the Deposit for the sole account and use of Seller as liquidated damages hereunder. Seller and Purchaser acknowledge and agree that (i) Seller’s actual damages upon the event of such a termination are difficult to ascertain with any certainty, (ii) a payment from Purchaser to Seller in the amount of the Deposit is a fair and reasonable estimate by the Parties of such aggregate actual damages of Seller, and (iii) such liquidated damages do not constitute a penalty. Any such payment shall be borne by VTLE and NOG in accordance with their respective Purchaser Pro Rata Shares.

(d) If this Agreement is terminated for any reason other than the reasons set forth in Sections 10.3(a), 10.3(b), or 10.3(c) Purchaser shall be entitled to receive the entirety of the Deposit, free of any claims by Seller or any other Person with respect thereto. In such event, Seller, VTLE and NOG shall execute and deliver joint written instructions to the Escrow Agent to disburse the Deposit (together with all earnings, interest and income thereon) to VTLE and NOG in accordance with their respective Purchaser Pro Rata Shares.

(e) Notwithstanding anything to the contrary herein but subject to the other terms and provisions of this Section 10.3, if a Party has failed to perform or observe in any material respect any of its agreements or covenants contained herein which are to be performed or observed (i) in the case where Seller or Purchaser is the non-performing Party, after the Closing, and (ii) in the case only where Seller is the non-performing Party, at, prior to, or after the Closing (including, if applicable pursuant to Section 10.3(a) above, the obligation of Seller to consummate the Closing, but specifically excluding the obligation of Purchaser to consummate the Closing), the other Party may seek specific performance of such covenant or agreement at any time prior to the valid termination of this Agreement without the necessity of posting bond or furnishing other security. Each Party understands and agrees that the other Party may suffer irreparable damage as a result of it failing to perform or observe in any material respect any of its agreements or covenants contained herein which are to be performed or observed after the Closing (or, in the case of Purchaser’s rights only under subpart (ii) above, at or prior to Closing as well). Accordingly, each Party waives any right it may have to challenge the enforceability of this Agreement by a decree of specific performance and agrees it will not argue in any proceeding that the requirements for specific performance have not been met, that monetary damages constitute a sufficient remedy or make any other argument in opposition to the specific performance of this Agreement.

(B) caused by, arising out of, or resulting from, Purchaser’s breach or nonfulfillment of, or failure to perform, any of Purchaser’s covenants or agreements contained in this Agreement to be performed after the Closing;

EVEN IF SUCH DAMAGES ARE CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY INDEMNIFIED PERSON, INVITEE, OR THIRD PARTY, AND WHETHER OR NOT CAUSED BY A PRE-EXISTING CONDITION, BUT EXCLUDING THE FRAUD, GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY INDEMNIFIED PERSON.

(b) Notwithstanding anything to the contrary contained in this Agreement, except in the case of Fraud, Seller Group’s and Purchaser Group’s sole and exclusive remedy against each other with respect to breaches of the representations, warranties, covenants, and agreements of the Parties contained in this Agreement (excluding Sections 6.4 and 6.6, which shall also be separately enforceable by Seller and Purchaser, as applicable, pursuant to whatever rights and remedies are available to it outside of this Article 11, and Section 4.6(a), the sole and exclusive remedy for which shall be pursuant to Section 2.3), and the affirmations of such representations, warranties, covenants, and agreements contained in the certificates respectively delivered by each Party at Closing pursuant to Sections 8.2(e) and 8.3(f), as applicable, are (i) set forth in this Article 11 (and, with respect to the representation and warranty in Section 4.7, in Section 2.3), (ii) the rights and remedies under the R&W Insurance Policy, and (iii) the right to seek specific performance, and if no such right of indemnification (or, with respect to the representations and warranty in Section 4.7, right under Section 2.3) is expressly provided, then such claims are hereby waived to the fullest extent permitted by Law.

(c) The Parties shall treat, for U.S. federal and applicable state and local income Tax purposes, any amounts paid pursuant to this Article 11 as an adjustment to the Purchase Price.

11.4 Indemnification Actions. All claims for indemnification under Section 6.4, Section 9.4 or Section 11.3 shall be asserted and resolved as follows:

-68-

(a) For purposes of this Article 11, the term “Indemnifying Person” when used in connection with particular Damages shall mean the Person having an obligation to indemnify another Person or Persons with respect to such Damages pursuant to this Article 11, and the term “Indemnified Person” when used in connection with particular Damages shall mean a Person having the right to be indemnified with respect to such Damages pursuant to this Article 11, Section 6.4 or Section 9.4 (including, for the avoidance of doubt, those Persons identified in Section 11.4(g)).

(b) To make a claim for indemnification under Section 6.4, Section 9.4 or Article 11, an Indemnified Person shall notify the Indemnifying Person of its claim, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a Third Party against the Indemnified Person (a “Claim”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person has actual knowledge of the Claim and shall enclose a complete copy of all papers (if any) served with respect to the Claim; provided that the failure of any Indemnified Person to give notice of a Claim as provided in this Section 11.4 shall not relieve the Indemnifying Person of its obligations under Section 6.4, Section 9.4 or Article 11, except to the extent such failure results in insufficient time being available to permit the Indemnifying Person to effectively defend against the Claim or otherwise materially prejudices the Indemnifying Person’s ability to defend against the Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant, or agreement, the Claim Notice shall specify the representation, warranty, covenant, or agreement that was inaccurate or breached and the basis of such inaccuracy or breach.

(c) In the case of a claim for indemnification based upon a Claim, the Indemnifying Person shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies its obligation to defend and indemnify the Indemnified Person against such Claim under Section 6.4, Section 9.4 or this Article 11, as applicable. If the Indemnifying Person does not notify the Indemnified Person within such thirty (30) day period regarding whether the Indemnifying Person admits or denies its obligation to defend the Indemnified Person, it shall be conclusively deemed obligated to provide such indemnification hereunder. The Indemnified Person is authorized, prior to and during such thirty (30) day period but prior to the Indemnifying Person admitting (or being deemed to have admitted such obligation pursuant to this Section 11.4(c)) its obligation to provide indemnification with respect to the matter in question, to file any motion, answer, or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Person and that is not prejudicial to the Indemnifying Person.

(d) If the Indemnifying Person admits its obligation (or is deemed to have admitted its obligation), it shall have the right and obligation to diligently defend and indemnify, at its sole cost and expense, the Claim. The Indemnifying Person shall have full control of such defense and proceedings, including, subject to the remainder of this Section 11.4(d), any compromise or settlement thereof. If requested by the Indemnifying Person, the Indemnified Person agrees to cooperate in contesting any Claim which the Indemnifying Person 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, at its own expense, participate in, but not control, any defense or settlement of any Claim controlled by the Indemnifying Person pursuant to this Section 11.4(d). An Indemnifying Person shall not, without the written consent of the Indemnified Person, settle any Claim or consent to the entry of any judgment with respect thereto that (i) does not result in a final, non-appealable, resolution of the Indemnified Person’s liability with respect to the Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person from all further liability in respect of such Claim) or (ii) may materially and adversely affect the Indemnified Person (other than as a result of money damages covered by the indemnity).

(e) If the Indemnifying Person does not admit its obligation or admits its obligation but fails to diligently defend, indemnify against, or settle the Claim, then the Indemnified Person shall have the right to defend against the Claim (at the sole cost and expense of the Indemnifying Person, if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing, subject to the right of the Indemnifying Person to admit its obligation to indemnify the Indemnified Person and assume the defense of the Claim at any time prior to settlement or final, non-appealable determination thereof. If the Indemnifying Person has not yet admitted its obligation to defend and indemnify the Indemnified Person, the Indemnified Person shall send written notice to the Indemnifying Person of any proposed settlement and the Indemnifying Person shall have the option for ten (10) days following receipt of such notice to (i) admit in writing its obligation for indemnification with respect to

-69-

such Claim and (ii) if its obligation is so admitted, assume the defense of the Claim, including the power to reject the proposed settlement. If the Indemnified Person settles any Claim over the objection of the Indemnifying Person after the Indemnifying Person has timely admitted its obligation for indemnification in writing (or is deemed to be obligated to indemnify such Indemnified Person pursuant to Section 11.4(c) or this Section 11.4(e)), the Indemnified Person shall be deemed to have waived any right to indemnity therefor.

(f) In the case of a claim for indemnification not based upon a Claim, the Indemnifying Person shall have thirty (30) days from its receipt of the Claim Notice to (i) cure the Damages complained of, (ii) admit its obligation to provide indemnification with respect to such Damages, or (iii) dispute the claim for such Damages. If the Indemnifying Person does not notify the Indemnified Person within such thirty (30) day period that it has cured the Damages or that it disputes the claim for such Damages, the Indemnifying Person shall be conclusively deemed to be obligated to provide indemnification hereunder, subject to the other provisions of this Article 11.

(g) Any claim for indemnity under Section 6.4, Section 9.4 or this Article 11 by any Affiliate, partner, member, shareholder, owner, officer, director, manager, employee, agent or Representative must be brought and administered by the applicable Party to this Agreement that is related to such Person. No Indemnified Person other than Seller shall have any rights against Purchaser under the terms of Section 6.4, Section 9.4 or this Article 11 except as may be exercised on its behalf by Seller, as applicable, pursuant to this Section 11.4(g). Seller may elect to exercise or not exercise indemnification rights under this Section 11.4 on behalf of the other Indemnified Persons affiliated with it in its sole discretion and shall have no liability to any such other Indemnified Person for any action or inaction under this Section 11.4.

11.5 Casualty and Condemnation.

(a) Subject to, and without limitation of, Seller’s representations, warranties, covenants and agreements made pursuant to this Agreement, if Closing occurs, then, from and after the Effective Date, Purchaser shall assume all risk of loss with respect to production of Hydrocarbons through normal depletion (including watering out of any Well, collapsed casing or sand infiltration of any Well) and the depreciation of any Equipment due to ordinary wear and tear, in each case, with respect to the Assets.

(b) If, after the Execution Date but prior to the Closing Date, any portion of the Assets is destroyed by fire or other casualty or is expropriated or taken in condemnation or under right of eminent domain (each, a “Casualty Loss”), then:

(i) Seller shall promptly notify Purchaser in writing following the occurrence of such Casualty Loss, which notice shall include reasonable detail of the nature of such Casualty Loss and Seller’s good faith estimate of the costs to repair or replace the relevant Asset(s);

(ii) Seller shall use commercially reasonable efforts to mitigate (or attempt to mitigate) any Damages resulting from, or relating to, such Casualty Loss;

(iii) Purchaser shall, subject to the other terms and conditions of this Agreement, nevertheless be required to proceed with Closing; and

(iv) Seller, at the Closing, shall pay to VTLE and NOG, in accordance with their respective Purchaser Pro Rata Shares, all sums paid or credited to Seller or any of its Affiliates by Persons by reason of such Casualty Loss insofar as with respect to the relevant Assets and shall assign, transfer and set over to VTLE and NOG or subrogate VTLE and NOG to all of Seller’s (and, if applicable, its Affiliates’) right, title and interest (if any) in and to any and all insurance claims, unpaid awards and other rights against any third Person arising out of or in connection with such Casualty Loss insofar as with respect to the Assets; provided, however, that Seller shall reserve and retain (and Purchaser shall assign to Seller if needed) (A) all rights, title, interests, and claims against Third Parties for the recovery of Seller’s costs and expenses (if any) incurred by Seller prior to Closing in pursuing or asserting any such insurance claims or other rights against Third Parties with respect to such Casualty Loss and (B) insurance proceeds recovered from Third Parties and attributable to any Environmental Defect that is attributable to a Casualty Loss after the Execution Date for which there was an adjustment to the Unadjusted Purchase Price pursuant to Article 3.

-70-

11.6 Limitation on Actions.

(a) The representations and warranties of Seller in Article 4, the corresponding representations, warranties, and affirmations given in the certificate delivered by Seller at Closing pursuant to Section 8.2(e), and the covenants and agreements of the Parties to be performed at or prior to Closing shall, in each case, not survive after the Closing Date. The representations and warranties of Purchaser in Article 5, and the corresponding representations, warranties, and affirmations given in the certificate delivered by Purchaser at Closing pursuant to Section 8.3(f), shall, in each case, survive the Closing indefinitely. The covenants and agreements of the Parties to be performed at any time from and after Closing shall survive Closing until fully performed. The remainder of this Agreement shall survive the Closing without time limit except as may otherwise be expressly provided herein. Representations, warranties, covenants, and agreements shall be of no further force and effect after the date of their expiration, provided that there shall be no termination of any bona fide claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant, or agreement prior to its expiration date (and, for purposes of clarity, there shall be no termination of any indemnification obligations underlying any such claim in such circumstance).

(b) The indemnities in Section 11.3(a) shall continue without time limit.

(c) The amount of any Damages for which an Indemnified Person is entitled to indemnity under this Article 11 shall be reduced by the amount of insurance proceeds realized by the Indemnified Person or its Affiliates with respect to such Damages (net of any collection costs, and excluding the proceeds of any insurance policy issued or underwritten by the Indemnified Person or its Affiliates); provided, however, that no Party shall be required to seek recovery under any policy of insurance as a condition to indemnification hereunder.

(d) Purchaser shall be subrogated to the rights of any Indemnified Person that is a member of the Seller Group against any insurer, indemnitor, guarantor or other Person with respect to the subject matter of any Damages subject to indemnification by Purchaser pursuant to Article 11 to the extent that Purchaser pays any such Indemnified Person with respect to such Damages. Any member of the Seller Group who is indemnified pursuant to Article 11 shall assign or otherwise cooperate with Purchaser in the pursuit of any claims against, and any efforts to recover amounts from, such other Person for any such Damages for which any member of the Seller Group has been paid. Any such Seller Group Indemnified Person shall remit to Purchaser within five (5) Business Days after receipt, any insurance proceeds or other payment that is received by any member of the Seller Group from a Third Party and which relates to Damages for which (but only to the extent) such member of the Seller Group has been previously compensated hereunder (minus the reasonable out-of-pocket costs incurred in obtaining such recovery).

(e) Any liability for indemnification hereunder shall be determined without duplication of recovery by reason of the same state of facts giving rise to such liability constituting (i) a breach of more than one representation, warranty, covenant, or agreement herein, (ii) a Purchase Price adjustment made hereunder, or (iii) covered by an obligation of indemnity hereunder.

(f) As used in this Agreement, the term “Damages” means the amount of any actual liability, loss, cost, expense, Tax, claim, award, or judgment incurred or suffered by any Person, whether attributable to personal injury or death, property damage, contract claims, torts, or otherwise, including reasonable fees and expenses of attorneys, consultants, accountants, or other agents and experts reasonably incident to the matters in question, and the costs of investigation and/or monitoring of such matters, and the costs of enforcement of the indemnity provided hereunder.

Exhibit 99.1

Vital Energy to Expand Delaware Basin Position Through Bolt-on Acquisition

Transaction highly accretive to key metrics; adds 68 high-return gross locations

TULSA, OK – July 28, 2024 - Vital Energy, Inc. (NYSE: VTLE) (“Vital Energy” or the “Company”) today announced the signing of a definitive joint purchase and sale agreement to acquire the assets of Point Energy Partners (“Point”), a Vortus Investments portfolio company. The transaction will significantly increase the Company’s operational scale and footprint in the Delaware Basin and add high-value development inventory. The agreement was signed in partnership with Northern Oil and Gas, Inc. (NYSE: NOG) (“NOG”). Under the terms of the agreement, the two companies will acquire Point Energy’s assets in an all-cash transaction for total consideration of $1.1 billion. Vital Energy agreed to acquire 80% of Point’s assets, with NOG acquiring the remaining 20%. The transaction is expected to close by the end of the third quarter of 2024 with an effective date of April 1, 2024, subject to customary closing conditions.

Closing price adjustments are expected to total approximately $75 million, reducing total consideration to approximately $1.025 billion. Vital Energy expects to fund its $820 million portion, net of expected purchase price adjustments, through the use of its credit facility, which was recently expanded to $1.5 billion. Wells Fargo, National Association has committed to the increased elected commitment upon closing of the transaction. Vital Energy plans to host a conference call and webcast at 8:00 a.m. CT on Monday, July 29, 2024. Supplemental slides have been posted to the Company’s website.

Highlights (all figures are net to Vital Energy):

Attractively priced, immediately accretive: The transaction is priced at approximately 2.4x next 12 months (NTM) Consolidated EBITDAX¹, as of the effective date, which compares favorably with Vital Energy’s current valuation and recent transactions in the basin. The purchase price is substantially underwritten by the value of proved developed producing reserves and eight work-in-process wells. Using SEC pricing, third-party reserve engineer Ryder Scott estimates the PDP reserves and work-in-process wells to have a PV-10, as of the effective date, of $742 million and $71 million, respectively. At closing, the transaction is projected to be immediately accretive to key financial metrics, including a >30% increase to NTM Adjusted Free Cash Flow¹ and a >20% increase to NTM Consolidated EBITDAX¹.

Adds high-return inventory and oil-weighted production: The transaction is expected to add 68 gross inventory locations (49 net) with an estimated average breakeven oil price of $47 per barrel NYMEX WTI. The assets include approximately 16,300 net acres and net production of approximately 30.0 thousand barrels of oil equivalent per day (“MBOE/d”) (67% oil), as of the effective date.

Robust hedges help ensure deleveraging: Vital Energy recently hedged a significant portion of its expected 2025 oil production to underpin cash flows and support leverage reduction targets. Leverage is expected to be approximately 1.5x at closing. At current strip commodity prices, the Company expects to reduce its leverage to approximately 1.3x within 12 months.

Expands Delaware Basin operational scale: Over the past 15 months, Vital Energy has built a high-quality, core operating position in the Delaware Basin, complementing its substantial Midland Basin leasehold. This transaction will increase the Company’s Delaware Basin position by approximately 25% to 84,000-net acres. Post closing, the Delaware Basin will comprise more than one third of the Company’s oil production.

“This bolt-on is a great fit for us, adding high-value inventory and production in the heart of our core operating areas. Furthermore, it expands our growing Delaware Basin position and balances our Permian operations. We expect to continue to demonstrate our ability to capture, integrate and create substantial value on acquired assets through optimized development plans, lower capital costs and proven operating practices, resulting in higher future cash flows,” said Jason Pigott, President and Chief Executive Officer.

Development and Production Expectations

Post closing, Vital Energy plans to moderate development activities on the properties relative to Point’s recent program. In March 2024, Point turned-in-line (“TIL”) a 15-well package, driving recent elevated production rates. No new TIL’s are planned prior to the closing of the transaction, leading to an estimated natural decline in daily production of approximately 50% from peak rates in April 2024.

With moderated activity levels and natural declines, fourth-quarter 2024 production on the Point asset is expected to average approximately 15.5 MBOE/d (64% oil). Vital Energy expects to invest approximately $45 million on the new properties during the fourth quarter of 2024, operating one drilling rig and completing seven wells.

The Company estimates a one rig development program would facilitate the drilling and completion of 12 wells over a 12-month period, resulting in total production of approximately 15.0 MBOE/d (64% oil) and capital investments of approximately $100 million.

This press release and any accompanying disclosures include financial measures that are not in accordance with generally accepted accounting principles (“GAAP”), such as Adjusted Free Cash Flow, Adjusted Net Income and Consolidated EBITDAX. While management believes that such measures are useful for investors, they should not be used as a replacement for financial measures that are in accordance with GAAP. For definitions of such non-GAAP financial measures, please see the supplemental financial information at the end of this press release. Due to the forward-looking nature of NTM Adjusted Free Cash Flow and NTM Consolidated EBITDAX, such measures could not be reconciled to the most directly comparable GAAP measure without unreasonable efforts. Unless otherwise specified, references to “average sales price” refer to average sales price excluding the effects of the Company’s derivative transactions.

All amounts, dollars and percentages presented in this press release are rounded and therefore approximate.

Adjusted Free Cash Flow

Adjusted Free Cash Flow is a non-GAAP financial measure that the Company defines as net cash provided by operating activities (GAAP) before net changes in operating assets and liabilities and transaction expenses related to non-budgeted acquisitions, less capital investments, excluding non-budgeted acquisition costs. Management believes Adjusted Free Cash Flow is useful to management and investors in evaluating operating trends in its business that are affected by production, commodity prices, operating costs and other related factors. There are significant limitations to the use of Adjusted Free Cash Flow as a measure of performance, including the lack of comparability due to the different methods of calculating Adjusted Free Cash Flow reported by different companies.

Consolidated EBITDAX

Consolidated EBITDAX is a non-GAAP financial measure defined in the Company’s Senior Secured Credit Facility as net income or loss (GAAP) plus adjustments for share-settled equity-based compensation, depletion, depreciation and amortization, impairment expense, organizational restructuring expenses, gains or losses on disposal of assets, mark-to-market on derivatives, accretion expense, interest expense, income taxes and other non-recurring income and expenses. Consolidated EBITDAX provides no information regarding a company’s capital structure, borrowings, interest costs, capital expenditures, working capital movement or tax position. Consolidated EBITDAX does not represent funds available for future discretionary use because it excludes funds required for debt service, capital expenditures, working capital, income taxes, franchise taxes and other commitments and obligations. However, management believes Consolidated EBITDAX is useful to an investor because this measure:

There are significant limitations to the use of Consolidated EBITDAX as a measure of performance, including the inability to analyze the effect of certain recurring and non-recurring items that materially affect the Company’s net income or loss and the lack of comparability of results of operations to different companies due to the different methods of calculating Consolidated EBITDAX, or similarly titled measures, reported by different companies. The Company is subject to financial covenants under the Senior Secured Credit Facility, one of which establishes a maximum permitted ratio of Net Debt, as defined in the Senior Secured Credit Facility, to Consolidated EBITDAX. See Note 7 in the 2023 Annual Report for additional discussion of the financial covenants under the Senior Secured Credit Facility. Additional information on Consolidated EBITDAX can be found in the Company’s Eleventh Amendment to the Senior Secured Credit Facility, as filed with the SEC on September 13, 2023.

PV-10

PV-10 is a non-GAAP financial measure that is derived from the standardized measure of discounted future net cash flows, which is the most directly comparable GAAP financial measure. PV-10 is a computation of the standardized measure of discounted future net cash flows on a pre-tax basis. PV-10 is equal to the standardized measure of discounted future net cash flows at the applicable date, before deducting future income taxes, discounted at 10 percent. Management believes that the presentation of PV-10 is relevant and useful to investors because it presents the discounted future net cash flows attributable to the Company’s estimated proved reserves prior to taking into account future corporate income taxes, and it is a useful measure for evaluating the relative monetary significance of the Company’s proved oil, NGL and natural gas assets. Further, investors may utilize the measure as a basis for comparison of the relative size and value of proved reserves to other companies. The Company uses this measure when assessing the potential return on investment related to proved oil, NGL and natural gas assets. However, PV-10 is not a substitute for the standardized measure of discounted future net cash flows. The PV-10 measure and the standardized measure of discounted future net cash flows do not purport to present the fair value of the Company’s oil, NGL and natural gas reserves of the property.
