PURCHASE PRICE

2.1 Purchase Price. The purchase price for the Assets (the “Purchase Price”) shall be Six Hundred and Fifteen Million, One Hundred and Eighty One Thousand, Two Hundred and Sixty Five Dollars ($615,181,265.00) (the “Unadjusted Purchase Price”) adjusted as provided in Section 2.3. On the same day as the execution and delivery of this Agreement, Purchaser has delivered or caused to be delivered to an account (the “Escrow Account”) at Wells Fargo Bank, National Association (the “Escrow Agent”), a wire transfer in the amount equal to seven and one-half percent (7.5%) of the Purchase Price in same-day funds (the “Deposit”) to be held, invested, and disbursed in accordance with the terms of this Agreement and an escrow agreement of even date herewith among Seller, Purchaser, and Escrow Agent (the “Escrow Agreement”). In the event the Closing occurs, the Deposit shall be credited against the Purchase Price to be paid by Purchaser at Closing and shall be retained, pursuant to Section 11.7, as the Indemnity Escrow (as defined below), in the Escrow Account established with the Escrow Agent to satisfy amounts that may be owed by Seller to Purchaser after Closing with respect to the indemnities of Seller under this Agreement and any special warranty claims under any Assignment and Bill of Sale. Such amount, and earnings thereon shall be retained in the Escrow Account following the Closing shall be referred to as the “Indemnity Escrow”. Any interest or earnings with respect to the Deposit held in the Escrow Account and included in the Indemnity Escrow shall be treated as income of Purchaser for federal income tax purposes; provided, that (i) Purchaser shall be entitled to quarterly tax distributions from the Escrow Account equal to 40% of such Escrow earnings and (ii) in no event will Seller be entitled to more than 60% of the Escrow earnings.

2.2 Allocated Values. Schedule 2.2 sets forth the agreed allocation of the Unadjusted Purchase Price among the Assets. The “Allocated Value” for any Property equals the portion of the Unadjusted Purchase Price that is allocated to such Property on Schedule 2.2, increased or decreased by a share of each adjustment to the Unadjusted Purchase Price under Sections 2.3(c), 2.3(d), 2.3(e), and 2.3(f). The share of each adjustment allocated to a particular Property shall be obtained by allocating that adjustment among the various Properties on a pro-rata basis in proportion to the Unadjusted Purchase Price allocated to each such Property on Schedule 2.2. Seller has accepted such Allocated Values for purposes of this Agreement and the transactions contemplated hereby, but otherwise makes no representation or warranty as to the accuracy of such values.

2.3 Adjustments to Purchase Price. The Unadjusted Purchase Price shall be adjusted as follows, but (i) in the case of Sections 2.3(c), 2.3(d) and 2.3(e), only to the extent identified on or before the Cut-Off Date; and (ii) in the case of Section 2.3(f), only to the extent paid or received on or before the Cut-Off Date:

(b) Without duplication of any adjustments made pursuant to Section 2.3(f), should Purchaser or any Affiliate of Purchaser receive after Closing any proceeds or other income to which Seller is entitled under Section 2.4(a), Purchaser shall fully disclose, account for, and promptly remit the same to Seller.

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

2.5 Procedures.

(a) For purposes of allocating production (and accounts receivable with respect thereto) under Section 2.3 and Section 2.4, (i) liquid Hydrocarbons shall be deemed to be “from or attributable to” the Properties when they pass through the pipeline flange connecting into the tank batteries related to each Well, and (ii) gaseous Hydrocarbons shall be deemed to be “from or attributable to” the Properties when they pass through the delivery point sales meters or similar meters at the point of entry into the pipelines through which they are transported.

The provisions of this Article 3, the special warranty of title in the Assignment and Bill of Sale, and the condition to closing in Section 7.2(d) provide Purchaser’s exclusive remedy with respect to any Title Defects or other deficiencies or defects in Seller’s title to the Properties.

(b) Purchaser’s rights with respect to title to the Properties pursuant to this Article 3 are limited to the Properties shown on Exhibit A-1, Exhibit A-2, and Exhibit A-5, and Seller hereby expressly disclaims and negates any and all warranties of title whatsoever, whether express, implied, statutory, or otherwise, except for the special warranty of title in the Assignment and Bill of Sale.

(u) depth severances or any other change in Seller’s Working Interest, Net Revenue Interest or Net Acre ownership for a Property with depth to the extent that they do not reduce Seller’s Net Acre ownership in, or Net Revenue Interest for, a Property below that shown on Exhibit A-1, Exhibit A-2, or Exhibit A-5 for such Property or increase Seller’s Working Interest for a Well beyond that shown on Exhibit A-2 for such Well without a corresponding increase in Seller’s Net Revenue Interest for such Well above that shown for such Well on Exhibit A-2;

(v) calls on production under existing Contracts, provided that the holder of such right must pay an index-based price for any production purchased by virtue of such call on production;

3.4 Environmental Assessment; Environmental Defects.

(a) From and after the Execution Date, and subject to the terms of Sections 6.1 and 6.5 and this Section 3.4, Purchaser shall have the right to conduct, or cause an environmental consulting or engineering firm (the “Environmental Consultant”), to conduct, an inspection of the environmental condition and compliance status of the Properties (the “Environmental Review”) which shall 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: E1527-13) (“Phase I”). Seller shall use commercially reasonable efforts to obtain permission from the operator of each Property for Purchaser or the Environmental Consultant to conduct the Environmental Review; provided, however, that Seller shall have no liability to Purchaser for failure to obtain such operator’s permission, and Seller shall not be required to make any payments or undertake any obligations for the benefit of any other Person with respect to such access. Seller shall have the right to have one or more representatives accompany Purchaser and the Environmental Consultant at all times during the Environmental Review. The Environmental Review shall not include any sampling, boring, operation of Equipment, or other invasive activity without the prior written consent of Seller, which consent can be withheld in Seller’s sole discretion, and that of any applicable third Person operator. In the event that (x) Purchaser, in its reasonable discretion based on the findings of Purchaser’s Environmental Review, determines that an

-18-

invasive test or procedure is needed with respect to Property and Purchaser requests in writing (which written notice shall be accompanied by any correspondence, reports or results regarding the finding on which the request is based and which Property is impacted by such finding) and does not obtain the written consent of Seller or an applicable third Person operator for such invasive test or procedure or (y) Purchaser is not granted access to a Property for the purpose of conducting its Environmental Review after notifying Seller in writing of such denial (if an applicable third Person operator has denied such access), Purchaser may, in its sole discretion exclude the affected Property and, (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-5 attached hereto and added to Schedule 1.3 attached hereto and (iv) such Property shall constitute an Excluded Asset for all purposes hereunder. In performing its Environmental Review, Purchaser shall (and shall cause the Environmental Consultant and Purchaser’s other representatives to): (1) perform all work in a safe and workmanlike manner; (2) 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; (3) materially comply with all applicable Laws; and (4) at its sole cost, risk, and expense, with respect to any physical damages caused by the Environmental Review, restore the Properties to their condition prior to the commencement of the Environmental Review.

(b) Purchaser shall provide to Seller (free of cost) copies (electronic or paper at Purchaser’s option) of any environmental reports and results (including any interim, draft or preliminary reports or results) generated by the Environmental Consultant to Seller promptly after request by Seller, such materials provided without any representation or warranty or any right of Seller to rely upon such materials, and the Seller hereby releases any claim it may have against Purchaser or the Environmental Consultant related to Seller’s reliance on such materials or Seller’s use thereof. 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 (including as may be required by deposition, interrogatories, requests for information or documents in legal or regulatory proceedings, subpoena, civil investigative demand or other similar process or 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 their respective officers, directors, employees, contractors, consultants (including the Environmental Consultant), and other advisors 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 Person without the consent of Purchaser or Seller, as applicable, which consent shall not be unreasonably withheld, conditioned or delayed. If this Agreement is terminated prior to the Closing, Purchaser 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 the Environmental Consultant), and other advisors with the immediately preceding sentence.

(c) Purchaser acknowledges that the Assets have been used for the exploration, development, and production of Hydrocarbons and that there may be petroleum, produced water, wastes, or other substances or materials located in, on, or under the Properties or associated with the Assets. Equipment and sites included in the Assets may contain hazardous materials, including asbestos and naturally occurring radioactive material (“NORM”). NORM may affix or attach itself to the inside of wells, materials, and equipment as scale, or in other forms. The wells, materials, and equipment located on the 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

-19-

this Section 3.4 or elsewhere in this Agreement, Seller makes no, and hereby disclaims any, representation or warranty, express or implied, with respect to the presence or absence of NORM, asbestos, mercury, drilling fluids and chemicals, and produced waters and Hydrocarbons in or on the Properties or Equipment.

3.5 Environmental Defects. As used in this Agreement, the term “Environmental Defect” means any condition, matter, obligation, or circumstance with respect to any given Asset that constitutes, or arises from, a breach of Environmental Law or that is soil, water, or groundwater contamination in excess of standards permitted under Environmental Law; provided, however, that the term “Environmental Defect” shall not include (i) current obligations to plug or abandon any well, (ii) NORM that does not meet or exceed actionable levels of contamination, or (iii) the matters that are disclosed on Schedule 3.5.

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

(a) To assert a claim arising out of a Title Defect, Purchaser must deliver a defect claim notice or notices to Seller on or before January 27, 2017 at 5:00 p.m. local time in Houston, Texas (the “Defect Claim Date”). Each such notice shall be in writing and shall include:

WITHOUT LIMITATION OF PURCHASER’S RIGHTS PURSUANT TO THE SPECIAL WARRANTY OF TITLE IN THE ASSIGNMENT AND BILL OF SALE, 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 SATISFIES ALL OF THE CONDITIONS AND REQUIREMENTS SET FORTH IN THIS SECTION 3.6(A).

(b) Should either Party discover any Title Benefit on or before the Defect Claim Date, such Party shall, as soon as practicable, but in any case by the Defect Claim Date, deliver to Purchaser a notice including:

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

WITHOUT LIMITATION OF PURCHASER’S RIGHTS SET FORTH IN SECTION 11.3(B)(III) WITH RESPECT TO SECTION 4.15 AND SECTION 11.3(B)(I) WITH RESPECT TO SECTION 11.2(G), 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 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 ENVIRONMENTAL DEFECT CLAIM NOTICE THAT SATISFIES ALL OF THE CONDITIONS AND REQUIREMENTS SET FORTH IN THIS SECTION 3.6(C).

(d) Purchaser agrees to provide written notification to Seller of any Title Defects, Title Benefits or Environmental Defects discovered by Purchaser, as soon as reasonably practicable after discovery thereof. Such written notification shall be preliminary and general in nature and need not conform to the notice provisions set forth in Sections 3.6(a), 3.6(b) and 3.6(c); provided, however, the Parties shall be obligated, upon notification from Seller, to discuss any matter set forth in any such written notification delivered hereunder. Further, Purchaser agrees to cooperate with Seller in reviewing and commenting on any curative materials provided by Seller (or Seller’s representatives) to Purchaser with

-21-

respect to potential Title Defects and Environmental Defects of which Seller is made aware of prior to Closing. Failure to comply with this Section 3.6(d) shall not be deemed a waiver of any of Purchaser’s rights hereunder with respect to such Title Defects, Title Benefits or Environmental Defects.

3.7 Cure; Removal.

(a) Seller shall have the right, but not the obligation, to attempt, at Seller’s sole cost, risk, and expense, to cure or remove, on or before ninety (90) days after the Closing Date (the “Cure Date”), any alleged Title Defects or Environmental Defects of which Seller has been advised by Purchaser pursuant to Section 3.6(a) or 3.6(c). To exercise such cure right Seller shall provide written notice to Purchaser of its intent to attempt to cure such alleged Title Defects or Environmental Defects on or before 5:00 p.m. local time in Houston, Texas on the date that is at least five (5) Business Days prior to the Closing Date. With respect to any Title Defect or Environmental Defect that Seller elects to cure pursuant to this Section 3.7(a), the Title Defect Amounts and Environmental Defect Amounts with respect to such Title Defect or Environmental Defect 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 one or more of such alleged Title Defects or Environmental Defects shall not affect the rights and obligations of the Parties under Section 3.10 with respect to dispute resolution. Seller’s election to attempt cure an alleged Title Defect or Environmental 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 Title Defect or Environmental Defect.

(b) With respect to any Title Defect or Environmental Defect which Seller has elected to attempt to cure pursuant to Section 3.7(a) above, subject to the determination by the Title Arbitrator or Environmental Arbitrator, as applicable, of the existence or Title Defect Amount or Environmental Defect Amount with respect to such a Title Defect or Environmental Defect, to the extent any such Title Defect or Environmental Defect is cured by Seller on or before the Cure Date, the amount of any previous deduction from the Unadjusted Purchase Price for such Title Defect or Environmental Defect shall be addressed as provided in Section 3.8(f).

(c) Any dispute relating to whether and to what extent a Title Defect or Environmental Defect has been cured shall be deemed to be 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 ten (10) Business Days after the Cure Date; provided, however, that any prior or concurrent determination by a Title Arbitrator or Environmental Arbitrator with respect to Title Defects or Environmental 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 pursuant to Section 3.7(a) shall be binding on the Parties with respect to such Title Defect or Environmental Defect (or factual or legal matters relating thereto, even if determined in connection with the resolution of an otherwise unrelated dispute).

(d) Seller, with respect to part (i) of this paragraph (d), and Seller and Purchaser with respect to part (ii) of this paragraph (d), shall have the right to exclude an Asset from this Agreement if (i) Purchaser’s estimate of a Title Defect Amount, as set forth in a notice delivered in accordance with 3.6(a) or (ii) Purchaser’s Environmental Consultant’s estimate of the Environmental Defect Amount, as set forth in a notice delivered in accordance with 3.6(c), in each case, exceeds fifty percent (50%) of the Allocated Value of the Asset(s) affected thereby, in which case, (A) the affected Asset shall not be conveyed to Purchaser at Closing, (B) the Unadjusted Purchase Price shall be reduced at Closing by the Allocated Value of such Asset, (C) such Asset shall be deemed to be deleted from Exhibit A-1, Exhibit A-2 and/or Exhibit A-5 attached hereto and added to Schedule 1.3 attached hereto and (D) such Asset shall constitute an Excluded Asset for all purposes hereunder

3.8 Adjustment for Title Defects and Benefits and Environmental Defects.

(a) With respect to each Property affected by Title Defects or Environmental Defects reported under Section 3.6(a) or 3.6(c), such Property shall be assigned at Closing subject to all uncured Title Defects and Environmental Defects, and the Purchase Price shall be reduced 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 an Environmental Defect, 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.

(b) With respect to each Property affected by Title Benefits reported under Section 3.6(b), the Unadjusted Purchase Price shall be increased for each Title Benefit by an amount as determined pursuant to Section 3.9(b) (the “Title Benefit Amount”), in each case as provided in Sections 3.8(d), 3.8(e) and 3.8(f), as applicable.

(c) Seller and Purchaser shall attempt to agree upon all 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) above, as applicable, and any corresponding Title Defect Amounts, Title Benefit Amounts, and Environmental Defect Amounts 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(a) with respect to Disputed Matters concerning Title Defects, Title Benefits, Title Defect Amounts and/or Title Benefit Amounts, and Section 3.10(b) with respect to Disputed Matters concerning Environmental Defects and/or Environmental Defect Amounts.

(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 notices and Environmental Defect notices in accordance with Sections 3.6(a) and 3.6(c)) related to (i) any Title Defects and Environmental Defects which Seller elects to attempt to cure pursuant to Section 3.7(a) or (ii) which are Disputed Matters (such aggregate amount, the “Defect Escrow Amount”), shall be deducted in the calculation of the Closing Payment, as provided in Section 8.4(a); and at the Closing, Purchaser shall deposit the Defect Escrow Amount into an escrow account established with Escrow Agent (the “Defect Escrow Account”). The Defect Escrow Amount shall be held, invested and disbursed in accordance with the terms of this Article 3 and the Escrow Agreement pending the curing or resolution of the applicable Title Defects and Environmental Defects. For the avoidance of doubt, the Defect Escrow Account shall be independent of and separate from the Escrow Account established for the Deposit and the Indemnity Escrow.

-23-

(f) After Closing the Purchase Price shall be adjusted for (i) any Title Defects and Environmental Defects which (A) Seller elects to attempt to cure pursuant to Section 3.7(a) and actually cures or (B) which are Disputed Matters and (ii) any Title Benefits which are Disputed Matters as provided in this Section 3.8(f). Within ten (10) Business Days after the determination of all Disputed Matters submitted to a Title Arbitrator or Environmental Arbitrator pursuant to Section 3.10(a) and Section 3.10(b), as applicable, the Parties shall, after giving effect to the limitations provided in Section 3.9, execute joint written instructions to the Escrow Agent instructing it to pay (i) to Purchaser, the sum of the Title Defect Amounts and Environmental Defect Amounts associated with (A) those Title Defects and Environmental Defects which Seller elected to attempt to cure pursuant to Section 3.7(a) which are not Disputed Matters and which are not fully cured as provided in Section 3.7 (provided however, if curative efforts by Seller mitigated an uncured Title Defect or Environmental Defect, the Title Defect Amount or Environmental Defect Amount associated with such Title Defect or Environmental Defect shall be revised pursuant to Section 3.9(a) or Section 3.9(c), as applicable) and (B) any Disputed Matters, determined in favor of Purchaser by the applicable Title Arbitrator or Environmental Arbitrator under Section 3.10(a) or Section 3.10(b), less any offsetting Title Benefits which are Disputed Matters and are determined in favor of Seller by the Title Arbitrator under Section 3.10(a) and (ii) to Seller, the remainder of Defect Escrow Amount. The Parties shall treat for Tax purposes, any amounts paid pursuant to this Section 3.8(f) as an adjustment to the Purchase Price and 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. Any post-Closing payment pursuant to this Section 3.8(f) shall bear interest from the Closing Date to the date of payment at the Agreed Rate (without duplication of interest at the Agreed Rate paid under any other provision of this Agreement).

(g) EXCEPT AS SET FORTH IN SECTION 4.15, SECTION 11.3(B)(I) WITH RESPECT TO SECTION 11.2(G), THE SPECIAL WARRANTY OF TITLE IN THE ASSIGNMENT AND BILL OF SALE, AND THE CONDITION TO CLOSING IN SECTION 7.2(D), THIS SECTION 3.8 SHALL, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BE THE EXCLUSIVE RIGHT AND REMEDY OF PURCHASER 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 PROPERTIES. IN THIS REGARD AND WITHOUT LIMITATION OF THE PRECEDING SENTENCE, IF PURCHASER, AS OF THE DEFECT CLAIM DATE, HAS KNOWLEDGE THAT A TITLE DEFECT OR OTHER DEFICIENCY IN TITLE TO THE ASSETS OR ENVIRONMENTAL DEFECT OR OTHER DEFECT OR DAMAGE RELATED TO THE ENVIRONMENTAL CONDITION OF THE PROPERTIES WHICH RESULTS FROM ANY MATTER WHICH COULD ALSO RESULT IN THE BREACH OF ANY REPRESENTATION OR WARRANTY OF SELLER AS SET FORTH IN ARTICLE 4 OF THE AGREEMENT (OTHER THAN SECTION 4.15), THEN PURCHASER SHALL ONLY BE ENTITLED TO ASSERT SUCH MATTER PRIOR TO THE DEFECT CLAIM DATE AS A TITLE DEFECT OR ENVIRONMENTAL DEFECT, AS APPLICABLE, IN EACH CASE, TO THE EXTENT PERMITTED BY THIS ARTICLE 3 AND SHALL BE PRECLUDED FROM ALSO ASSERTING SUCH MATTER AS THE BASIS OF THE BREACH OF ANY SUCH REPRESENTATION OR WARRANTY. FURTHER, WITHOUT LIMITING THE PRECEDING SENTENCES, EXCEPT AS PROVIDED IN SECTION 3.6(A) AND SECTION 3.6(C), PURCHASER 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 un conditionally 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 and (B) the amount of Net Acres set forth for such Lease in Exhibit A-1 or Exhibit A-5 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 and the number of Net Acres set forth for such Lease in Exhibit A-1 or Exhibit A-5, as applicable, and the denominator of which is the Net Acres set forth for such Lease in Exhibit A-1 or Exhibit A-5, as applicable;

(iv) if the Title Defect represents a discrepancy between (A) the Seller’s Net Revenue Interest for any Property and (B) the Net Revenue Interest stated in Exhibit A-1, Exhibit A-2 or Exhibit A-5 for such Property, and for which there is not any change in the Seller’s Working Interest or Net Acre ownership for such Property from that set forth in Exhibit A-1, Exhibit A-2 or Exhibit A-5, as applicable, for such Property, as applicable, then the Title Defect Amount shall be the product of the Allocated Value of such Property multiplied by a fraction, the numerator of which is the decrease in Seller’s Net Revenue Interest and the denominator of which is Seller’s Net Revenue Interest stated on Exhibit A-1, Exhibit A-2 or Exhibit A-5 for such Property; provided, however, that if the Title Defect does not affect the Property 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) above, 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;

(vi) if a Title Defect is reasonably susceptible of being cured, the Title Defect Amount shall be no greater than the reasonable cost and expense of curing such Title Defect;

(vii) 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

-25-

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

(A) an individual claim for a Title Defect for which a valid 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 One Hundred Thousand Dollars ($100,000);

(B) 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; and

(C) there shall be no adjustment to the Purchase Price for Title Defects unless and until the aggregate of all Title Defect Amounts which would generate an adjustment to the Unadjusted Purchase Price pursuant to Section 3.9(a)(viii)(A) exceeds two and one-half percent (2.5%) of the Unadjusted Purchase Price, and then only to the extent that such aggregate amount exceeds two and one-half percent (2.5%) of the Unadjusted Purchase Price.

(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 and (B) amount of Net Acres shown for such Lease in Exhibit A-1 or Exhibit A-5, then the Title Benefit Amount shall be the product of the Allocated Value of such Lease multiplied by a fraction, the numerator of which is difference between the number of Net Acres owned by Seller in such Lease and the number of Net Acres set forth for such Lease in Exhibit A-1 or Exhibit A-5, as applicable, and the denominator of which is the Net Acres set forth for such Lease in Exhibit A-1 or Exhibit A-5, as applicable;

(iii) if the Title Benefit represents a discrepancy between (A) the Net Revenue Interest for any Property and (B) the Net Revenue Interest stated with respect to such Property in Exhibit A-1, Exhibit A-2 or Exhibit A-5, the Title Benefit Amount shall be the product of the Allocated Value of the affected Property multiplied by a fraction, the numerator of which is the Net Revenue Interest increase and the denominator of which is the Net Revenue Interest stated in Exhibit A-1, Exhibit A-2 or Exhibit A-5 with respect to such Property; provided, however, that if the Title Benefit does not affect a Property throughout the entire productive life of the Property, 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) above, 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;

(v) notwithstanding anything to the contrary in this Article 3, an individual claim for a Title Benefit shall only generate an adjustment to the Unadjusted Purchase Price if the Title Benefit Amount with respect thereto exceeds One Hundred Thousand Dollars ($100,000); and

-26-

(vi) there shall be no adjustment to the Purchase Price for Title Benefits unless and until the aggregate of all Title Benefit Amounts which would generate an adjustment to the Unadjusted Purchase Price pursuant to Section 3.9(b)(v) exceeds two and one-half percent (2.5%) of the Unadjusted Purchase Price, and then only to the extent that such aggregate amount exceeds two and one-half percent (2.5%) of the Unadjusted Purchase Price.

(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 under Environmental Laws that addresses the applicable Environmental Defect applying Environmental Laws as of the Defect Claim Date in the most cost effective manner reasonably available and commercially reasonable and practical (considered as a whole taking into consideration any material negative impact such response may have on the operations of the relevant Assets (as currently operated) and any potential material additional costs or liabilities that may likely arise as a result of such response);

(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

(A) an individual claim for an Environmental Defect for which a valid 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 One Hundred Thousand Dollars ($100,000) (for avoidance of doubt the value of any single Environmental Defect that affects multiple Properties may be aggregated across such multiple Properties for purposes of determining if this amount has been met); and

(B) there shall be no adjustment to the Unadjusted Purchase Price for Environmental Defects unless and until the aggregate of all Environmental Defect Amounts which would generate an adjustment to the Unadjusted Purchase Price pursuant to Section 3.9(c)(iv)(A) exceeds two and one-half percent (2.5%) of the Unadjusted Purchase Price, and then only to the extent that such aggregate amount exceeds two and one-half percent (2.5%) of the Unadjusted Purchase Price.

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. With respect to any Disputed Title Matters which Purchaser has not submitted to the Title Arbitrator or the Houston, Texas office of the American Arbitration Association, as applicable, within the relevant time periods set forth above (or, with respect to Disputed Title Matters concerning Title Defects Seller has elected to attempt to cure pursuant to Section 3.7(a), the date set forth in Section 3.7(c)), Purchaser shall be deemed to have waived its dispute of such Disputed Title Matters, as applicable.

(b) Except as provided in Section 3.7(c), with respect to any Disputed Matter concerning Environmental Defects and Environmental Defect Amounts (“Disputed Environmental Matters”), on or before a date that is ten (10) Business Days following the Closing Date, Purchaser shall 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 in which the applicable Property or Properties are located, as selected by mutual agreement of Purchaser and Seller (the “Environmental Arbitrator”). If Purchaser and Seller have not agreed upon a Person to serve as Environmental Arbitrator during such ten (10) Business Day period, Purchaser shall, within five (5) 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 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. With respect to any Disputed Environmental Matters which Purchaser has not submitted to the Environmental Arbitrator or the Houston, Texas office of the American Arbitration Association, as applicable, within the relevant time periods set forth above (or, with respect to Disputed Environmental Matters concerning Environmental Defects Seller has elected to attempt to cure pursuant to Section 3.7(a), the date set forth in Section 3.7(c)), Purchaser shall be deemed to have waived its dispute of such Disputed Environmental Matters, as applicable.

(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 Environmental Arbitrator may consult with and engage disinterested third Persons 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 Matters 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 to any Title Arbitrator or Environmental Arbitrator pursuant to this Section 3.10. Purchaser shall bear one-half of the costs and expenses of the Title Arbitrator and Environmental Arbitrator, and Seller shall be responsible for the remaining one-half of the costs and expenses.

(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 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 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, Seller shall not be required to make any payments or undertake any material obligations for the benefit of the holders of any un-obtained Material Consents subject to this Section 3.12(b).

(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 is not obtained by Closing, either Party may 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-5 attached hereto and added to Schedule 1.3 attached hereto and (iv) such Property shall constitute an Excluded Asset for all purposes hereunder.

(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); (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 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.

Purchase Price adjustments calculated in the same manner as the adjustments in Section 2.3 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.

Purchaser hereby agrees that, with respect to the representations and warranties of Seller contained in Article 4, until five (5) Business Days prior to the Closing, Seller may supplement or amend the Seller Disclosure Schedules with respect to any matter hereafter arising after the Execution Date which, if existing at the Execution Date, would have been required to be set forth or described in such Seller’s Disclosure Schedule. In the event that Seller supplements or amends the Seller Disclosure Schedules pursuant to the preceding sentence, Seller shall deliver a copy of the amendment or supplement (in either case, the “Supplemental Disclosure”) to the Purchaser. The Purchaser shall have five (5) days after receipt of a Supplemental Disclosure (the “Termination Period”) in which to review the Supplemental Disclosure or request additional information related thereto. If a Supplemental Disclosure discloses facts that would constitute a breach of the Seller’s representations and warranties hereunder and such breach would result in the failure of the Purchaser’s condition to Closing specified in Section 7.2(a) to be satisfied at the Closing, the Purchaser may terminate this Agreement pursuant to Section 10.1(b) by delivering a termination notice to the Seller within the Termination Period (which termination notice shall specify the representation or warranty breached, identify the specific facts in the Supplemental Disclosure that constitute the breach, and describe why the failure of such condition would reasonably be expected to occur); provided, however, that the termination of this Agreement pursuant to a termination notice delivered as provided in this Section 6.15 shall not be effective unless the Seller fails to cure such breach within ten (10) Business days following the date the Seller receives such termination notice; provided further, however, that in the event such breach is not capable of being cured by Seller, the termination of this Agreement pursuant to such termination notice shall be effective as of the date such termination notice was delivered to Seller. Notwithstanding anything herein to the contrary, except as provided in Article 11, Seller expressly acknowledges and agrees that if the Closing shall occur, Purchaser shall not

-48-

waive or release (nor shall Purchaser be deemed to have waived or released) any indemnification claims to which it is entitled to make with respect to any matters disclosed pursuant to any Supplemental Disclosure against any member of the Seller Group for indemnification with respect thereto pursuant to the terms of this Agreement or otherwise.

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. Seller shall bear one-half and Purchaser shall bear one-half of the costs and expenses of the Accounting Arbitrator. Within ten (10) days after the earlier of (i) the expiration of Purchaser’s thirty (30) day review period without delivery of any written report or (ii) the date on which the Parties or the Accounting Arbitrator finally determine the Purchase Price, (x) Purchaser shall pay to Seller the amount by which the Purchase Price (less the Deposit) exceeds the Closing Payment or (y) Seller shall pay to Purchaser the amount by which the Closing Payment exceeds the Purchase Price (less the Deposit), as applicable. Any post-Closing payment pursuant to this Section 8.4 shall bear interest from the Closing Date to the date of payment at the Agreed Rate (without duplication of interest at the Agreed Rate paid under any other provision of this Agreement).

(c) Purchaser shall pay (or cause to be paid) prior to delinquency, all Asset Taxes that become due after the Closing Date. Purchaser shall send to Seller a statement that apportions each Asset Tax pursuant to this Section 9.1(c) based upon the amount of Asset Taxes actually invoiced and paid to the applicable Governmental Authority by Purchaser. 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 Seller’s allocated portion of such Asset Taxes less any amounts reflected as a reduction in the purchase price for the Assets.

9.2 Transfer Taxes. To the extent that any sales, purchase, transfer, stamp, documentary stamp, registration, use or similar taxes (“Transfer Taxes”) are payable by reason of the sale of the Assets under this Agreement, such Transfer Taxes shall be borne and timely paid by Purchaser.

Seller and Purchaser agree to retain all books and records with respect to Tax matters pertinent to the Assets relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations of the respective taxable periods and to abide by all record retention agreements entered into with any Governmental Authority.

9.4 1031 Like-Kind Exchange Cooperation. Seller and Purchaser agree that either or both of Seller and Purchaser may elect to treat the acquisition or sale of the Assets as an exchange of like-kind property under section 1031 of the Code (an “Exchange”). Each Party agrees to use reasonable efforts to cooperate with the other Party in the completion of such an Exchange including an Exchange subject to the procedures outlined in Treasury Regulation Section 1.1031(k)-1 and/or Internal Revenue Service Revenue Procedure 2000-37. Each of Seller and Purchaser shall have the right at any time prior to Closing to assign its rights under this Agreement to a qualified intermediary (as that term is defined in Treasury Regulation Section 1.1031(k)-1(g)(4)(v)) or an exchange accommodation titleholder (as that term is defined in Internal Revenue Service Revenue Procedure 2000-37) to effect an Exchange. In connection with any such Exchange, any exchange accommodation title holder shall have taken all steps necessary to own the Assets under applicable Law. Each Party acknowledges and agrees that neither an assignment of a Party’s rights under this Agreement for purposes of an Exchange nor any other actions taken by a Party or any other person in connection with the Exchange shall release any Party from, or modify, any of their respective liabilities and obligations (including indemnity obligations to each other) under this Agreement, and no Party makes any representations as to any particular Tax treatment that may be afforded to any other Party by reason of such assignment or any other actions taken in connection with the Exchange. Any Party electing to treat the acquisition or sale of the Assets as an Exchange shall be obligated to pay all additional costs incurred hereunder as a result of the Exchange, and in consideration for the cooperation of the other Party, the Party electing Exchange treatment shall agree to pay all costs associated with the Exchange and to indemnify and hold the other Party, its Affiliates, and its and their respective former, current and future partners, members, shareholders, owners, officers, directors, managers, employees, agents and representatives harmless from and against any and all Damages and taxes arising out of, based upon, attributable to or resulting from the Exchange or transactions or actions taken in connection with the Exchange that would not have been incurred by the other Party but for the electing Party’s Exchange election.

9.5 Allocation of Purchase Price. Schedule 9.5 sets forth the allocation of the Purchase Price, Assumed Obligations, and any other items constituting consideration for applicable income Tax purposes (to the extent known at such time) among the Assets in accordance with Section 1060 of the Code (and the Treasury Regulations promulgated thereunder). Seller and Purchaser agree to amend Schedule 9.5 to reflect adjustments to the Purchase Price and to report the transactions contemplated by this Agreement consistently with Schedule 9.5, as adjusted by the Parties, on any Tax Return, including Internal Revenue Service Form 8594, and will not assert, and will cause their Affiliates not to assert, in connection with any Tax audit or other proceeding with respect to Taxes, any asset values or other items inconsistent with the amounts set forth on Schedule 9.5 except with the agreement of the other Parties or as required by applicable Law.

-55-

This Agreement may be terminated at any time prior to Closing: (a) by the mutual prior written consent of Seller and Purchaser, (b) by Purchaser pursuant to Section 6.15, if applicable, or (c) by either Seller or Purchaser if the Closing has not occurred on or before the earlier to occur of (i) February 28, 2017 or (ii) the expiration of any applicable cure period provided to Seller pursuant to Section 6.8 with respect to a breach that is the subject of a termination notice delivered by Purchaser pursuant to Section 6.15; provided, however, that, no Party shall be entitled to terminate this Agreement under Section 10.1(b) if the Closing has failed to occur because such Party failed to perform or observe in any material respect its covenants and agreements hereunder or such Party is in material breach of its representations and warranties set forth in this Agreement.

10.2 Effect of Termination. If this Agreement is terminated pursuant to Section 10.1, subject to the remainder of this Section 10.2 and Section 10.3, this Agreement shall become void and of no further force or effect (except for the provisions of Article 1, this Article 10, Sections 3.4(b), 4.9, 4.16, 5.8, 5.9, 5.10, 5.11, 6.3, 6.5, 6.11, 11.4 (as it relates to claims under Section 6.5), 12.2, 12.3, 12.6, 12.7, 12.8, 12.9, 12.11, 12.13, 12.14, 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. Notwithstanding anything to the contrary in this Agreement, the termination of this Agreement under Section 10.1 shall not relieve any Party from liability for any failure to perform or observe in any material respect any of its agreements or covenants contained herein that are to be performed or observed at or prior to Closing or its material breach of its representations and warranties set forth in this Agreement. In the event this Agreement is terminated by Seller under Section 10.1, and Purchaser 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 at or prior to Closing or is in material breach of its representations and warranties set forth in this Agreement, then Seller shall be

-56-

entitled, at its sole and exclusive remedy, to retain the Deposit, free of any claims by Purchaser or any other Person. In such event, Seller and Purchaser shall execute and deliver joint written instructions to the Escrow Agent to disburse the Deposit together with any income thereon to Seller. It is expressly stipulated by the Parties that the actual amount of Damages resulting from any termination of the type set forth in this Section 10.2 would be difficult to determine accurately because of the unique nature of this Agreement, the unique nature of the Assets, the uncertainties of applicable commodity markets and differences of opinion with respect to such matters, and that the Parties hereby agree and acknowledge that the amount of the Deposit hereunder (a) represents a reasonable estimate of the minimum amount of Damages that the Seller would suffer as a result of such a termination and (b) represents reasonable consideration for the Seller removing the Assets from the marketplace during the period from the Execution Date until the such a termination hereof. In the event this Agreement is terminated by Purchaser under Section 10.1, and Seller 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 at or prior to Closing or is in material breach of its representations and warranties set forth in this Agreement, then Purchaser shall receive back the Deposit, free of any claims by Seller or any other Person (and in such event, Seller and Purchaser shall execute and deliver joint written instructions to the Escrow Agent to disburse the Deposit together with any income thereon to Purchaser) and Purchaser shall be entitled to all remedies available at Law and shall be entitled to recover court costs and attorneys’ fees in addition to any other relief to which Purchaser may be entitled whether under this Agreement or otherwise. Notwithstanding anything to the contrary herein, if a Party has the right to terminate this Agreement under Section 10.1 and the other 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 at or prior to Closing or is in material breach of its representations and warranties set forth in this Agreement, in lieu of terminating this Agreement or seeking its other remedies provided for in this Section 10.2, it may seek specific performance 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 at or prior to Closing or being in material breach of its representations and warranties set forth in this Agreement. 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.

10.3 Distribution of Deposit Upon Termination. If this Agreement is terminated for any reason, other than a termination by Seller as permitted pursuant to Section 10.1 and of the Purchaser 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 at or prior to Closing or is in material breach of its representations and warranties set forth in this Agreement, Seller shall deliver to Purchaser the Deposit, free of any claims by Seller or any other Person with respect thereto. In such event, Seller and Purchaser shall execute and deliver joint written instructions to the Escrow Agent to disburse the Deposit together with any income thereon to Purchaser.

11.4 Indemnification Actions. Except as provided in Article 11, all claims for indemnification under Section 6.5, Section 9.4 or Section 11.3 shall be asserted and resolved as follows:

(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 6.5 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 6.5, 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 Person 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 6.5, 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 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 6.5, 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 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 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).

-61-

(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 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 obligated to provide indemnification hereunder, subject to the other provisions of this Article 11.

(g) Any claim for indemnity under Section 6.5, Section 9.4 or 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 and Purchaser shall have any rights against Seller or Purchaser under the terms of Section 6.5, Section 9.4 or Article 11 except as may be exercised on its behalf by Purchaser or Seller, as applicable, pursuant to this Section 11.4(g). Seller and Purchaser 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 the Seller’s representations, warranties and covenants made pursuant to this Agreement, from and after the Effective Date, if Closing occurs, 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”), Purchaser shall nevertheless be required to close and Purchase shall have the option to (i) require Seller, at the Closing, to pay to Purchaser all sums paid to Seller by non-Affiliate third Persons by reason of such Casualty Loss insofar as with respect to the Assets and shall

-62-

assign, transfer and set over to Purchaser or subrogate Purchaser to all of Seller’s right, title and interest (if any) in insurance claims, unpaid awards and other rights against non-Affiliate third Persons arising out of such Casualty Loss insofar as with respect to the Assets; provided, however, that Seller shall reserve and retain (and Purchaser shall assign to Seller) all rights, title, interests and claims against third Persons who are not Affiliates of Seller for the recovery of Seller’s costs and expenses incurred prior to the Closing in pursuing or asserting any such insurance claims or other rights against such third Persons with respect to any such Casualty Loss or (ii) exclude the affected Assets from the transactions contemplated by this Agreement, in which case (A) the affected Asset shall not be conveyed to Purchaser at Closing, (B) the Unadjusted Purchase Price shall be reduced at Closing by the Allocated Value of such Asset, (C) such Asset shall be deemed to be deleted from Exhibit A-1, Exhibit A-2 and/or Exhibit A-5 attached hereto and added to Schedule 1.3 attached hereto and (D) such Asset shall constitute an Excluded Asset for all purposes hereunder.

11.6 Limitation on Actions.

(a) The representations and warranties of Seller in Article 4 (excluding Sections 4.1, 4.3, 4.7, 4.9, 4.10, and 4.14) and the covenants and agreements of the Parties in Article 6, (excluding Sections 6.5 and 6.7), and the corresponding representations, warranties, and affirmations given in the certificates delivered at Closing pursuant to Sections 8.2(f) and 8.3(e), as applicable, shall survive the Closing for a period of twelve (12) months and the representations and warranties of Seller set forth in Section 4.3 shall survive the Closing until the expiration of the applicable statute of limitations. The representation and warranty of Seller set forth in Section 4.7 shall survive the Closing until the Cut-Off Date. The remainder of this Agreement shall survive the Closing and delivery of the Assignment and Bill of Sale 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 (if applicable), 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.

(b) The indemnities in Sections 11.3(a)(ii), 11.3(a)(iii), 11.3(b)(ii), and 11.3(b)(iii) shall terminate as of the termination date of each respective representation, warranty, covenant, or agreement that is subject to indemnification thereunder, except in each case as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Person on or before such termination date in accordance with Section 11.4. The indemnity in Section 11.3(b)(i) shall survive the Closing without time limit except that such indemnity shall survive (i) as set forth in Sections 2.3 and 2.4 with respect to Section 11.2(b) and (ii) until the expiration of the applicable statute of limitations with respect to the matters set forth in Sections 11.2(c), 11.2(d), 11.2(e), 11.2(f), 11.2(g) and 11.2(l). The indemnities in Sections 11.3(a)(i) and 11.3(a)(iv) shall survive the Closing without time limit.

(c) No Party shall have any liability for any indemnification under Section 11.3, for an individual matter until and unless the amount of the liability for Damages with respect to which such Party admits (or it is otherwise finally determined that such Party has) an obligation to indemnify the other Party pursuant to the terms of Section 11.3 exceeds One Hundred Thousand Dollars ($100,000) (the “Individual Indemnity Threshold”). Without limiting the foregoing, Seller shall not have any liability for any indemnification under Sections 11.3(b)(ii) or 11.3(b)(iii) until and unless the aggregate amount of the liability for all Damages (i) for which Claim Notices are delivered by Purchaser under Sections 11.3(b)(ii) and 11.3(b)(iii), (ii) with respect to which Seller admits (or it is otherwise finally determined) that Seller has an obligation to indemnify Purchaser pursuant to the terms of under Sections 11.3(b)(ii) or 11.3(b)(iii), and (iii) which exceed the Individual Indemnity Threshold exceeds two percent (2.0%) of the Unadjusted Purchase Price, and then only to the extent such Damages exceed two percent (2.0%) of the Unadjusted Purchase Price. Notwithstanding the foregoing, this Section 11.6(c) shall not limit

-63-

indemnification for breach of the (A) Retained Obligations set forth in Section 11.2(a), 11.2(b), 11.2(c), 11.2(k), 11.2(h), 11.2(i), and 11.2(j), (B) representations and warranties in Sections 4.1, 4.3, 4.9, 4.10, 4.14, (C) Purchaser’s representations and warranties in Article 5, (D) the covenants and agreements set forth in Sections 6.5 or 6.7, or (E) the indemnity obligations set forth in 11.3(a)(iv).

(d) Notwithstanding anything to the contrary contained elsewhere in this Agreement, Seller shall not be required to indemnify Purchaser under Sections 11.3(b)(ii) and 11.3(b)(iii) for aggregate Damages in excess of fifteen percent (15%) of the Unadjusted Purchase Price; provided, however, that this Section 11.6(d) shall not limit indemnification for breach of the representations and warranties in Sections 4.1, 4.3, 4.9, 4.10, 4.14, or the covenants and agreements set forth in Section 6.7.

(e) Notwithstanding anything in this Agreement to the contrary, Seller shall have no obligation to indemnify any Indemnified Person for any Damages resulting from any environmental remediation, removal or other response action undertaken by any Indemnified Person to the extent attributable to the (i) costs of such remediation, removal or other response action in excess of the least stringent permissible legal cleanup standard under Environmental Law or required by a Governmental Authority, in each case, existing as of the Closing Date or, if more stringent, as required under the express remediation obligations set forth in any applicable Lease, or (ii) costs results from meeting a more stringent cleanup standard resulting from a change in land use by an Indemnified Person from the use in effect as of the Closing Date.

(f) With respect to any investigation, remediation or other response action related to Damages for which Purchaser seeks indemnification from Seller pursuant to this Article 11, Purchaser hereby agrees to provide Seller with copies of all related reports and communications submitted to any Governmental Authority and the results of all sampling and analysis activities within three (3) Business Days after receipt thereof by Purchaser.

(g) 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.

(h) Any Purchaser Group Indemnified Person shall remit to Seller, within five (5) Business Days after receipt, any insurance proceeds or other payment that is received by any member of the Purchaser Group from a third Person and which relates to Damages for which (but only to the extent) such member of the Purchaser Group has been previously compensated hereunder (minus the reasonable out-of-pocket costs incurred in obtaining such recovery).

(i) Any 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 Person 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).

11.7 Indemnity Escrow. In order to provide security for Seller’s indemnification obligations under this Article 11 and Seller’s special warranty granted in the Assignment and Bill of Sale, the Indemnity Escrow shall be held by Escrow Agent, and disbursed by Escrow Agent after the Closing in accordance with this Section 11.7 and the Escrow Agreement. With respect to each claim for indemnification asserted by Purchaser against Seller pursuant to this Article 11 or special warranty claim

-64-

asserted by Purchaser pursuant to the Assignment and Bill of Sale and Section 3.1(c) during the period from and after the Closing Date up to the date that is twelve (12) months following the Closing Date (the “Escrow Termination Date”), upon final resolution or determination of such an indemnity or special warranty claim by the Parties or in accordance with Section 11.4, as applicable, Purchaser and Seller shall jointly instruct Escrow Agent to disburse to Purchaser the amount set forth in such joint instruction, which will be that portion of the Indemnity Escrow being held in the Escrow Account as would satisfy such finally resolved or determined indemnity or special warranty claim. On the Escrow Termination Date, Seller shall be entitled to receive the Indemnity Escrow balance as of such time and such amount shall be automatically distributed to Seller pursuant to the terms of the Escrow Agreement (and Purchaser and Seller shall jointly instruct Escrow Agent to take any necessary actions in order to accomplish the foregoing). If there are remaining amounts due by Seller to Purchaser pursuant to the indemnity obligations under this Article 11 after the Indemnity Escrow balance is exhausted, then such amounts shall be promptly paid to Purchaser by Seller as they are agreed by the Parties or finally determined in accordance with the terms of this Agreement. To the extent that Purchaser asserts any Damages for which it believes it is entitled to indemnification pursuant to this Article 11 or any special warranty claims pursuant to the Assignment and Bill of Sale and Section 3.1(c), Purchaser shall pursue such claims against the Indemnity Escrow first, and Seller shall not have any personal liability for such claims unless and until the Indemnity Escrow is exhausted, and then only as further limited in accordance with the terms of this Agreement. On the date that is six (6) months following the Closing Date, Seller and Purchaser shall jointly instruct the Escrow Agent to disburse to Seller fifty percent (50%) of the amount of the Indemnity Escrow balance as of such time, excluding those amounts attributable to any claim for indemnification asserted as of such date by Purchaser against Seller pursuant to this Article 11 or special warranty claim asserted by Purchaser pursuant to the Assignment and Bill of Sale and Section 3.1(c) that has not been previously satisfied as of such date.

12.6 Governing Law. This Agreement and the legal relations between the Parties shall be governed by and construed in accordance with the Laws of the State of Texas, without regard to principles of conflicts of Laws that would direct the application of the Laws of another jurisdiction.

12.7 Venue; Waiver of Jury Trial. Each Party consents to personal jurisdiction in any action brought in the United States federal courts located in the State of Texas with respect to any dispute, claim, or controversy arising out of, in relation to, or in connection with, this Agreement, and each of the Parties agrees that any action instituted by it against the other with respect to any such dispute, controversy, or claim (except to the extent a dispute, controversy, or claim arising out of, in relation to, or in connection with, title or environmental matters pursuant to Section 3.10 or the determination of Purchase Price adjustments pursuant to Section 8.4(b) is referred to an expert pursuant to those Sections) will be instituted exclusively in the United States District Court for the Southern District of Texas, Houston Division. Each Party (a) irrevocably submits to the exclusive jurisdiction of such courts, (b) waives any objection to laying venue in any such action or proceeding in such courts, (c) waives any objection that such courts are an inconvenient forum or do not have jurisdiction over it, and (d) agrees that service of process upon it may be effected by mailing a copy thereof by registered mail (or any substantially similar form of mail), postage prepaid, to it at its address specified in Section 12.2. The foregoing consents to jurisdiction and service of process shall not constitute general consents to service of process in the State of Texas for any purpose except as provided herein and shall not be deemed to confer any rights on any Person other than the Parties to this Agreement. THE PARTIES HEREBY WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY ANY PARTY AGAINST ANOTHER IN ANY MATTER WHATSOEVER ARISING OUT OF, IN RELATION TO, OR IN CONNECTION WITH, THIS AGREEMENT.

12.8 Captions. The captions in this Agreement are for convenience only and shall not be considered a part of or affect the construction or interpretation of any provision of this Agreement.

12.9 Waivers. Any failure by any Party to comply with any of its obligations, agreements, or conditions herein contained may be waived by the Party to whom such compliance is owed by an instrument signed by the Party to whom compliance is owed and expressly identified as a waiver, but not in any other manner. No course of dealing on the part of Seller or Purchaser, or their respective Affiliates and its and their respective former, current and future partners, members, shareholders, owners, officers, directors, managers, employees, agents and representatives or any failure by Seller or Purchaser to exercise any of its rights under this Agreement shall operate as a waiver thereof or affect in any way the right of such Party at a later time to enforce the performance of such provision. No waiver of, or consent to a change in, any of the provisions of this Agreement shall be deemed or shall constitute a waiver of, or consent to a change in, other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided.

12.10 Assignment. Other than as permitted by Section 9.4, no Party shall assign (including by change of control, merger, consolidation, or stock purchase) or otherwise transfer all or any part of this Agreement to any third Person, nor shall any Party delegate any of its rights or duties hereunder (including by change of control, merger, consolidation, or stock purchase) to any third Person, without the prior written consent of the other Party and any transfer or delegation made without such consent shall be void ab initio. Any assignment of this Agreement permitted by this Section 12.10 shall be made subject to the obligations contained in this Agreement and such assignment shall not relieve the assigning Party of any obligations and responsibilities hereunder. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and assigns.

12.11 Entire Agreement. This Agreement, the Confidentiality Agreement and the documents to be executed hereunder and the exhibits and schedules attached hereto and thereto constitute the entire agreement among the Parties pertaining to the subject matter hereof, and supersede all prior agreements, understandings, negotiations, and discussions, whether oral or written, of the Parties pertaining to the subject matter hereof. In entering into this Agreement, neither Party has relied on any statement, representation, warranty, covenant, or agreement of the other Party or its representatives other than those expressly contained in this Agreement. For the avoidance of doubt, this Agreement constitutes a “definitive written agreement” as contemplated by the Confidentiality Agreement and, as such, upon Closing the Confidentiality Agreement shall automatically terminate, effective as of the Closing Date, or if Closing does not occur, the Confidentiality Agreement shall survive in accordance with its terms.

12.12 Amendment. This Agreement may be amended or modified only by an agreement in writing signed by Seller and Purchaser and expressly identified as an amendment or modification.

12.13 No Third-Person Beneficiaries. Nothing in this Agreement shall entitle any Person other than Purchaser and Seller to any claim, cause of action, remedy or right of any kind, except the rights expressly provided to the Persons described in Section 6.5, Section 9.4 and Article 11.

12.14 Severability. If any provision of this Agreement, or any application thereof, is held invalid, illegal, or unenforceable in any respect under any Law, this Agreement shall be reformed to the extent necessary to conform, in each case consistent with the intention of the Parties, to such Law, and, to the extent such provision cannot be so reformed, then such provision (or the invalid, illegal, or unenforceable application thereof) shall be deemed deleted from (or prohibited under) this Agreement, as the case may be, and the validity, legality, and enforceability of the remaining provisions contained herein (and any other application of such provision) shall not in any way be affected or impaired thereby.

12.15 Time of the Essence. Time is of the essence in this Agreement. If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date which is not a Business Day), then the date for giving such notice or taking such action (and the expiration of such period during which notice is required to be given or action taken) shall be the next day which is a Business Day.

Seller and Purchaser have had the opportunity to exercise business discretion in relation to the negotiation of the details of the transaction contemplated hereby. This Agreement is the result of arm’s-length negotiations from equal bargaining positions. It is expressly agreed that this Agreement shall not be construed against any Party, and no consideration shall be given or presumption made, on the basis of who drafted this Agreement or any particular provision hereof.

12.18 Limitation on Damages. Notwithstanding anything to the contrary contained herein, neither Purchaser nor Seller, nor any of their respective Affiliates shall be entitled to consequential, special, or punitive damages in connection with this Agreement and the transactions contemplated hereby (other than consequential, special, or punitive damages suffered by third Persons for which responsibility is allocated between the Parties) and Purchaser and Seller, for themselves and on behalf of their respective Affiliates, hereby expressly waive any right to consequential, special, or punitive damages in connection with this Agreement and the transactions contemplated hereby (other than consequential, special, or punitive damages suffered by third Persons for which responsibility is allocated between the Parties).

12.19 Joint and Several Liability. Seller agrees and acknowledges that each of Development, Upstream and Midstream shall be jointly and severally liable for the obligations of Seller under this Agreement.

This power of attorney and all authority conferred hereby is granted and

conferred subject to the interests of the other Parties to this Agreement, and in consideration of those interests and for the purpose of completing the transactions contemplated hereby, this power of attorney and all authority conferred hereby shall be irrevocable and shall not be terminated by the Seller Entities or by operation of Law or by the occurrence of any other event. Purchaser shall be fully protected in relying conclusively without any investigation upon any notices, instruction, dealings, and actions of Development within the scope of this Section 12.20 and the power of attorney contained herein.
