BUYER’S REPRESENTATIONS AND WARRANTIES

Section 5.1 Organization and Standing. Buyer is a limited liability company duly organized, validly existing and in good standing under the laws of the State of Delaware and is duly qualified to carry on its business in each state where failure to be so qualified could reasonably be expected to adversely affect the Assets or consummation of the transactions contemplated by this Agreement.

Section 5.2 Power. Buyer has all requisite power and authority to carry on its business as presently conducted and to execute, deliver and perform this Agreement and all documents required to be executed and delivered by Buyer at Closing. The execution, delivery and performance of this Agreement (and such documents) do and will not violate, or be in conflict with, any provision of Buyer’s governing documents or any provisions of any material agreement or instrument to which it is a party or by which it is bound, or any judgment, decree, order, statute, rule or regulation applicable to Buyer.

Section 5.3 Authorization and Enforceability. The execution, delivery and performance by Buyer of this Agreement (and all documents required to be executed and delivered by Buyer at Closing), and the consummation of the transactions contemplated hereby (and thereby) have been duly and validly authorized by all necessary action on behalf of Buyer. This Agreement constitutes (and, at Closing, such documents shall constitute) Buyer’s legal,

valid and binding obligation, enforceable against Buyer in accordance with its terms, subject, however, to the effects of bankruptcy, insolvency, reorganization, moratorium and similar laws for the protection of creditors, as well as to general principles of equity, regardless of whether such enforceability is considered in a proceeding in equity or at law. The Conflicts Committee has (i) granted “Special Approval” with regard to this Agreement under the First Amended and Restated Agreement of Limited Partnership of Memorial Production Partners LP dated as of December 14, 2011 (as amended) and (ii) recommended that the board of directors of Memorial Production Partners GP LLC authorize and approve the execution and delivery of this Agreement by Buyer.

Section 5.6 Securities Law, Access to Data and Information. Buyer is familiar with the Company Interests and the Assets, is a knowledgeable, experienced and sophisticated investor in the oil and gas business, and is an “accredited investor” as such term is defined in Regulation D of the Securities Act. Buyer understands and accepts the risks and absence of liquidity inherent in ownership of the Company Interests. Buyer acknowledges that the Company Interests may be deemed to be “securities” under the Securities Act and certain applicable State securities or blue sky laws, and that resales thereof may therefore be subject to the registration requirements of such acts. The Company Interests are being acquired solely for Buyer’s own account for the purpose of investment and not with a view to resale, distribution or granting a participation therein in violation of any securities Laws.

Section 5.7 Financing. Buyer has, or will have by Closing, financing sufficient to pay the Purchase Price in cash at Closing as contemplated by this Agreement. Buyer is solvent and will not be rendered insolvent by the transactions contemplated by this Agreement.

Section 6.2 Confidentiality.

(a) All data and information, whether written or oral, obtained from Seller or any Company Entity in connection with the transactions contemplated hereby, including the Records, whether obtained by Buyer before or after the execution of this Agreement, and data and information generated by Buyer based on data or information obtained from Seller or any Company Entity in connection with the transactions contemplated hereby (collectively, the “Information”), is deemed by the Parties to be confidential. Until the Closing, except as required by Law, Buyer and its officers, agents and representatives shall hold in strict confidence all Information, except any Information which:

(i) At the time of disclosure by Seller or any Company Entity is in the public domain;

(ii) After disclosure by Seller becomes part of the public domain by publication or otherwise, except by breach of this commitment by Buyer;

(iii) Buyer can establish was rightfully in its possession at the time of disclosure by Seller;

(iv) Buyer rightfully received from third Persons (non-Affiliates) free of any obligation of confidence;

(v) Is developed independently by Buyer without the Information, provided that the Person or Persons developing the data shall not have had access to the Information; or

(vi) The disclosure of which is reasonably necessary in order to comply with applicable Transfer Requirements or Preferential Rights, notices required to be given under applicable contracts or to seek approvals and consents of Governmental Authorities for the conveyance of any Assets or the transactions contemplated hereby.

(b) Return of Information. If Closing does not occur and this Agreement is terminated, if Seller so requests at any time, Buyer shall: (i) return to Seller all copies of the Information in its possession obtained pursuant to any provision of this Agreement, which Information is at the time of termination required to be held in confidence pursuant to this Section 6.2; and (ii) destroy any and all notes, reports, studies or analyses based on, or incorporating, the Information. The terms of this Section 6.2 shall survive termination of this Agreement.

(c) Injunctive Relief. Buyer agrees that Seller shall not have an adequate remedy at law if Buyer violates any of the terms of this Section 6.2. In such event, Seller shall have the right, in addition to any other they may have, to obtain injunctive relief to restrain any breach or threatened breach of the terms of this Section 6.2, or to obtain specific enforcement of such terms.

Section 6.3 SEC Matters. Seller acknowledges that Buyer and its Affiliates may be required to include financial statements and other financial information relating to the Assets (“SEC Financial Statements”) in documents filed with the SEC by Buyer and its Affiliates pursuant to the Securities Act or the Exchange Act, and that such SEC Financial Statements may be required to be audited. In that regard, prior to the Closing and subsequent to the Closing to the extent Seller is then in existence, Seller hereby covenants and agrees (i) to provide reasonable and customary assistance to Buyer in connection with the preparation of the SEC Financial Statements and (ii) to provide Buyer reasonable access to such records (to the extent Seller has such information) and personnel of Seller as Buyer may reasonably request to enable Buyer, and its representatives and accountants, at Buyer’s sole cost and expense, to prepare and have audited such SEC Financial Statements. Buyer shall reimburse Seller for any out of pocket expenses incurred by Seller in providing such assistance and access, provided that such expenses were incurred with Buyer’s prior written consent. Notwithstanding anything to the contrary herein, Seller shall provide Buyer and its independent accountants with access to any and all existing financial information, books, records, and documents in its possession that relate to the Company Entities (subject to any privilege or confidentiality obligations) and other data relating to the Assets relevant to the periods being audited.

Section 6.4 Casualty or Condemnation Loss.

(a) If, after the date of this Agreement but prior to the Closing Date, any portion of the Assets is destroyed by fire or other casualty or is taken in condemnation or under right of eminent domain (“Casualty Loss”), and the loss as a result of such

Casualty Loss individually or in the aggregate exceeds 1.5% of the unadjusted Purchase Price, Seller shall have the option to exclude any affected Assets from the transactions contemplated by this Agreement and reduce the Purchase Price by the aggregate Allocated Values of such excluded Assets. If Seller opts to exclude any such Asset (collectively, the “Retained Assets”), Seller shall retain such Retained Assets or cause the applicable Company Entity to assign such Retained Assets to Seller before Closing. If Seller elects not to elect the option to exclude such affected Assets, Buyer shall, at Seller’s election, nevertheless be required to consummate the transactions contemplated hereby, and Seller shall elect, by written notice to Buyer delivered at least five Business Days prior to Closing, in the case of fire or other casualty, either (i) to cause the Assets affected by any such Casualty Loss to be repaired or restored to at least their condition prior to such Casualty Loss, at Seller’s sole cost, risk and expense, as promptly as reasonably practicable (which work must be completed by the Closing Date), or (ii) to indemnify Buyer and the Company Entities in a manner reasonably acceptable to Buyer against any Losses that Buyer or the Company Entities reasonably incur to repair the Assets subject to any such Casualty Loss. In the case of condemnation or eminent domain, the Parties shall work together in good faith to reduce the Purchase Price by an amount equal to the Allocated Value (or applicable portion thereof) of the Assets (or portion thereof) taken in condemnation or under right of eminent domain. In each case, the Company Entities shall retain all rights to insurance and other claims against third Persons with respect to the Casualty Loss, except to the extent the Parties otherwise agree in writing.

(b) If, after the date of this Agreement but prior to the Closing Date, any portion of the Assets experiences a Casualty Loss, and the loss as a result of such Casualty Loss individually or in the aggregate is 1.5% or less of the unadjusted Purchase Price, Buyer shall nevertheless be required to close and Seller shall, at Closing, pay to Buyer all sums (if any) paid to Seller by third Persons by reason of such Casualty Loss and shall assign, transfer and set over to Buyer or subrogate Buyer to all of Seller’s right, title and interest (if any) in insurance claims, unpaid awards, and other rights against third Persons arising out of the Casualty Loss.

Section 6.5 Further Assurances. Each Party shall use its respective commercially reasonable efforts to obtain all approvals and consents required by or necessary for the transactions contemplated hereby, and to ensure that all of the conditions to its respective obligations contained in Article 9 or Article 10, as applicable, are satisfied as soon as reasonably practicable.

Section 6.6 Notification of Certain Matters. Seller and Buyer shall each give prompt written notice to the other of (a) the occurrence, or failure to occur, of and shall provide accurate and complete copies of any and all information relating to, any event of which it becomes aware that has caused or that would be likely to cause any representation or warranty of such Party contained in this Agreement to be untrue or inaccurate in any material respect at any time from the date hereof to the Closing, and (b) the failure of such Party (or, in the case of Seller, any Company Entity), or any officer, director, manager, employee, or agent thereof, to comply with or satisfy in any material respect any covenant, condition, or agreement to be complied with or satisfied by it hereunder. A notifying Party under this Section 6.6 shall use all

commercially reasonable efforts to cure or remedy, before the Closing, any occurrence of any event described in (a) or (b) in the preceding sentence. If any event described in (a) or (b) above occurs and the applicable Party fails to give notice thereof in accordance with this Section 6.6 but such event is cured prior to the Closing Date, such Party shall have no liability for such failure to give notice, and such failure to give notice shall not constitute a breach of this Section 6.6.

Section 6.7 Tax Matters.

(a) The Parties acknowledge that the purchase and sale of the Company Interests by and between Buyer and Seller is treated as a purchase and sale of the Assets for federal income Tax purposes and shall be reported accordingly.

(b) Tax and Tax Return Responsibilities.

(i) Except as otherwise provided herein, each Party shall bear all Taxes imposed on it as a result of the transactions contemplated by this Agreement, except that Buyer shall be responsible for any Texas franchise Tax imposed with respect to the ownership and operation of the Assets for the period between the Effective Time and the Closing Date; provided for the avoidance of doubt, however, that Buyer shall not be responsible for any Texas franchise Tax attributable to any income or gain recognized as a result of the sale of the Company Interests pursuant to this Agreement. Each Party shall timely file, to the extent required by or permissible under applicable Law, all Tax Returns and other documentation with respect to any such Taxes.

(ii) Seller shall prepare or cause to be prepared the Company’s U.S. federal and state income Tax Returns for all Pre-Closing Periods and any other Tax Returns of the Company that are due on or before the Closing Date.

(iii) Buyer shall prepare or cause to be prepared all other Tax Returns of the Company for Pre-Closing Periods (“Pre-Closing Tax Returns”). Such Pre-Closing Tax Returns shall be prepared on a basis consistent with past practice except to the extent otherwise required by applicable Law. Reasonably in advance of filing, which shall be no later than 10 days prior to the due date for filing any such Pre-Closing Tax Return, Buyer shall deliver a copy of each such Pre-Closing Tax Return, together with all supporting documentation and workpapers, to Seller for its review and reasonable comment. Buyer will cause each such Pre-Closing Tax Return (as revised to incorporate Seller’s reasonable comments) to be timely filed and will provide a copy to Seller.

(iv) Buyer shall prepare or cause to be prepared all Tax Returns of the Company for all Straddle Periods (“Straddle Tax Returns”). Such Straddle Tax Returns shall be prepared on a basis consistent with past practice except to the extent otherwise required by applicable Law. Reasonably in advance of filing, which shall be no later than 20 days prior to the due date for filing any such Straddle Tax Return, Buyer shall deliver a copy of each such Straddle Tax Return,

together with all supporting documentation and workpapers, to Seller for its review and reasonable comment. Buyer will cause each such Straddle Tax Return (as revised to incorporate Seller’s reasonable comments) to be timely filed and will provide a copy to Seller.

(v) Neither Buyer nor any of its Affiliates shall amend, re-file, revoke or otherwise modify any Tax Return or Tax election of the Company (or any successor(s) thereof) with respect to a Pre-Effective Period without the prior written consent of Seller.

(vi) If after the Closing Date, the Company receives a Tax refund or credit that is attributable to a Pre-Effective Period, then Buyer shall cause the Company reasonably promptly thereafter to pay to Seller the amount of such refund or credit together with any interest thereon.

(c) Each Party shall use commercially reasonable efforts to cooperate fully with the other Party, as and to the extent reasonably requested by the other Party and at the requesting Party’s expense, in connection with the filing of Tax Returns and any proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any such proceeding and making employees (to the extent such employees were responsible for the preparation, maintenance or interpretation of information and documents relevant to Tax matters or to the extent required as witnesses in any Tax proceedings), available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Each Party agrees to retain all of its books and records with respect to Tax matters pertinent to the Company relating to any taxable period beginning before the Closing Date until the expiration of the applicable statute of limitations and to abide by all record retention agreements entered into with any Governmental Authority.

(d) Buyer shall be responsible for and pay all sales, transfer, use and similar taxes arising from or associated with the transfer to Buyer (other than taxes based on income or gain) and all costs and expenses (including recording fees and real estate transfer taxes and real estate transfer stamps) incurred in connection with the purchase of the Company Interests hereby.

(e) If notice of any audit, examination or other proceeding with respect to Taxes of the Company (a “Tax Claim”) shall be received by either Party for which the other Party may reasonably be expected to be liable pursuant to Article 13, the notified Party shall notify such other Party in writing of such Tax Claim; provided, however, that the failure of the notified Party to give the other Party notice as provided herein shall not relieve such failing Party of its obligations under Article 13, except to the extent that the other Party is actually and materially prejudiced thereby.

(f) On or prior to the Closing Date, the Parties shall agree in writing on the allocation of the Purchase Price among the Assets in accordance with Section 1060 of the Code and the Treasury Regulations promulgated thereunder, which shall be consistent

with the Allocated Values. Buyer and Seller shall report the transactions contemplated under this Agreement on all federal, state and local Tax Returns, including Internal Revenue Service Form 8594, which the Parties shall timely file with the Internal Revenue Service, in a manner consistent with such allocation. Buyer and Seller agree that they or any of their respective Affiliates shall not take any position inconsistent with such allocation in any Tax Return, in notices to Governmental Authorities, in audit or other proceedings with respect to Taxes, in notices to preferential purchase right holders or in other documents or notices relating to the transactions contemplated by this Agreement unless required to do so by a final determination as defined in Section 1313 of the Code. The Parties shall confer and cooperate on any revisions to the allocation of the Purchase Price, including reporting any matters that require updating to be consistent with the agreed allocation.

Section 6.8 Directors and Officers Indemnity.

(a) For a period of four years from and after the Closing, Buyer shall indemnify and hold harmless each Person who has been at any time prior to the Closing an officer or director of any Company Entity (each an “Indemnified Officer and Director” and collectively, the “Indemnified Officers and Directors”) but only to the extent that such Indemnified Officer and Director was entitled to indemnification from Propel Sub immediately prior to the date hereof or from the Company immediately prior to the Closing Date under the Organizational Documents of such Company Entity in such Indemnified Officer and Director’s capacity as an officer or director of such Company Entity, regardless of whether such contracts are terminated on or after the Closing. The procedures associated with such indemnification shall be the same (or in any event no less favorable to the Indemnified Officers and Directors) as those associated with the Indemnified Officer and Director’s indemnification from the applicable Company Entity immediately prior to the date hereof (provided, however, that Buyer shall have no obligation under any “change-in-control” or similar provisions.

(b) For a period of four years from and after the Closing, Buyer shall cause the Organizational Documents of each Company Entity to contain provisions no less favorable to the Indemnified Officers and Directors than those contained in such Organizational Documents immediately prior to the date hereof, with respect to Propel Sub, or the Closing Date, with respect to the Company, regarding indemnification and the procedures associated with such indemnification. If Buyer, any of the Company Entities or any of their successors or assigns (i) consolidates with or merges with any other Person and shall not be the continuing or surviving entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, in any case, proper provision shall be made so that the successors and assigns of Buyer, such applicable Company Entity or applicable successor or assign shall assume the obligations set forth in this Section 6.8.

(c) The provisions of this Section 6.8 are intended to be for the benefit of, and shall be enforceable by, the Parties, each Indemnified Officer and Director and their respective heirs and representatives.

Section 6.9 Formation and Contribution. Seller will, before Closing, form the Company as a newly-formed wholly-owned subsidiary of Seller with an entity name selected by Buyer and provided to Seller prior to its formation (but in no event provided later than 10 Business Days before the Closing Date), and such name subject to Seller’s approval, not to be unreasonably withheld. At its formation, the Company will have no assets or liabilities of any kind or character. Prior to Closing, Seller will (and will cause the Company and its other applicable subsidiaries to) execute and deliver the Assignment and Assumption Agreement pursuant to which Seller will assign the Assets (and only the Assets) to the Company and the Company will assume only the liabilities and obligations set forth in such Assignment and Assumption Agreement.

Section 6.10 Non-Operated Property Matters. Subject to Section 6.1(y), if between the date hereof and the Closing the operator of any Non-Operated Asset proposes any operation or action with respect to such Non-Operated Asset, Seller will promptly notify Buyer of such proposal and shall vote in favor of (or against), or grant (or withhold) consent to, such operation or action as directed by Buyer in its sole discretion.

ARTICLE 7

TITLE DEFECTS

Section 7.1 Title Examination and Access; Disclaimer and Special Warranty.

(a) Examination. Buyer may make or cause to be made at its expense such examination as it may desire of Seller’s or any Company Entity’s title to the Assets. For such purposes, until the Defect Notice Time, Seller and the Company Entities shall give to Buyer and its representatives full access during their respective regular hours of business to all of the files, records, contracts, correspondence, maps, data, reports, plats, abstracts of title, lease files, well files, unit files, division order files, production marketing files, title opinions, title files, title records, ownership maps, surveys, and any other information, data, records, and files that they have relating in any way to the title to the Assets, the past or present operation thereof, and the marketing of production therefrom, except, however, where restricted by license agreements or other agreements or contracts with a non-affiliated third party.

(b) General Disclaimer of Title Warranties and Representations. Except for the special warranty of title as set forth in Section 7.1(c) and without limiting Buyer’s remedies for Title Defects set forth in this Article 7, Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to its or the Company Entities’ title to any of the Properties, and Buyer hereby acknowledges and agrees that (except for breaches of any of the covenants set forth in this Agreement, for which Buyer will have the remedies provided in Article 13) Buyer’s sole remedy for any Title Defect, with respect to any of the Properties shall be as set forth in or pursuant to this Article 7.

(c) Special Warranty. If the Closing occurs, then effective as of the Closing Date, Seller warrants Defensible Title as of the Closing Date to the ▇▇▇▇▇ and Leases unto the Company Entities against any Person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under the Company Entities, but not otherwise, subject, however, to the Permitted Encumbrances.

Section 7.2 Title Defects.

(a) As used herein, the term “Title Defect” shall mean any matter affecting any Asset that causes Seller (prior to Closing) or the applicable Company Entity (from and after Closing) to have less than Defensible Title to such Asset. In evaluating whether a matter constitutes a Title Defect, due consideration shall be given to whether such matter is of the type expected to be encountered in the area involved as determined by reasonable and prudent operators and is customarily acceptable to reasonable and prudent operators in such area. Buyer shall notify Seller of Title Defects (“Title Defect Notices”) no later than 5:00 p.m. Houston, Texas time on September 13, 2013 (the “Defect Notice Time”). Each Title Defect Notice shall be in writing and include: (i) a specific description of the alleged Title Defect(s); (ii) the Assets affected; (iii) a detailed explanation of the basis for the alleged Title Defect; (iv) supporting documents reasonably sufficient for Seller to verify the existence of the alleged Title Defect(s); (v) the amount by which Buyer reasonably believes in good faith the Allocated Values of the affected Asset(s) are reduced by the alleged Title Defect(s) (the “Title Defect Value”); and (vi) the computations upon which Buyer’s belief is based.

(b) For each Title Defect timely asserted in a Title Defect Notice, Seller shall have the option of (i) attempting to Cure (at Seller’s (and not the Company Entities’) sole cost) the Title Defect, (ii) contesting in good faith the Title Defect or Buyer’s good faith estimate of the Title Defect Value in accordance with Section 7.4, or (iii) reducing the Purchase Price by Buyer’s good faith estimate of the Title Defect Value set forth in the Title Defect Notice, subject to the limitations set forth in this Article 7. Seller shall notify Buyer in writing of its election no more than four Business Days following its receipt of a Title Defect Notice, and Seller’s failure to timely deliver a notice shall be deemed an election under clause (iii) of the preceding sentence.

(c) From the date hereof through the Defect Notice Time, the Parties will use good faith commercially reasonable efforts to meet biweekly, whether in person or via conference call, to discuss the status of Buyer’s Title Defect review.

Section 7.3 Title Defect Value. The Title Defect Value shall be determined pursuant to the following guidelines, where applicable:

(a) If the Title Defect is that the actual Net Revenue Interest attributable to any Well (or the specified zone(s) therein) is less than that stated in Exhibit B and there is a corresponding proportionate decrease in Working Interest, then the Title Defect Value is the product of the Allocated Value of such Asset multiplied by a fraction, the numerator of which is the difference between the Net Revenue Interest set forth in Exhibit B and the actual Net Revenue Interest, and the denominator of which is the Net Revenue Interest stated in Exhibit B;

(b) If the Title Defect results from (i) Seller or a Company Entity, as applicable, having a greater Working Interest in a Well (or the specified zone(s) therein) than the Working Interest specified therefor in Exhibit B without a corresponding increase in the Net Revenue Interest or (ii) Seller or a Company Entity, as applicable, having a lesser Net Revenue Interest in a Well (or the specified zone(s) therein) than the Net Revenue Interest specified therefor in Exhibit B without a corresponding decrease in the Working Interest for such Well, the Title Defect Value shall be equal to the present value (discounted at 10% compounded annually) of the Parties’ agreed good faith estimate of the decreased value of such Well (or the specified zone(s) therein) for the period from and after the Effective Time which is attributable to such increase in Seller’s or the Company Entity’s, as applicable, Working Interest or decrease in Seller’s or the Company Entity’s, as applicable, Net Revenue Interest;

(c) If the Title Defect results from the existence of a lien, security interest, pledge, or collateral assignment, the Title Defect Value shall be an amount sufficient to fully discharge such lien, security interest, pledge, or collateral assignment;

(d) If the Title Defect results from any matter not described in paragraphs (a), (b) or (c) above, the Title Defect Value shall be an amount equal to the difference between the value of the Well(s) (or the specified zone(s) therein) or other Asset with such Title Defect and the value of the Well(s) (or the specified zone(s) therein) or other Asset without such Title Defect (taking into account the Allocated Value of the affected Asset); and

(e) If a Title Defect is not effective or does not affect a Well (or the specified zone(s) therein) or other Asset throughout the entire productive life of such Well (or the specified zone(s) therein) or other Asset, such fact shall be taken into account in determining the Title Defect Value.

Section 7.4 Contested Title Defects. With respect to any Title Defect timely asserted by a Title Defect Notice and not Cured, if Seller contests in good faith the existence of such Title Defect or Buyer’s good faith estimate of the Title Defect Value, then Seller shall so notify Buyer in writing no later than the earlier of (i) 10 Business Days after Buyer’s delivery to Seller of such Title Defect Notice or (ii) September 20, 2013 (a “Title Defect Rejection Notice”), which Title Defect Rejection Notice shall state with reasonable specificity the basis of Seller’s rejection of the Title Defect or of such Title Defect Value. For any Title Defect asserted by Buyer in a Title Defect Notice by the Defect Notice Time, if Seller fails to timely deliver a Title Defect Rejection Notice, then (a) Seller shall be deemed to have accepted the validity of such Title Defect and such Title Defect Value and (b) the Purchase Price shall be reduced, subject to Section 7.5, by an amount equal to such Title Defect Value unless such Title Defect is Cured. If Seller timely delivers a Title Defect Rejection Notice with respect to any Title Defect, then representatives of the Parties, knowledgeable in title matters, shall promptly (but in any event no later than five Business Days after delivery of the Title Defect Rejection Notice) meet and attempt to agree on whether such alleged Title Defect exists and, if so, the Title Defect Value applicable thereto. If the Parties are unable to reach agreement with respect to any Title Defects, the Title Defect or the Title Defect Value subject to the Title Defect Rejection Notice shall be submitted to arbitration in accordance with the procedures set forth in Section 8.8.

Section 7.5 Limitations on Adjustments for Title Defects. Notwithstanding the provisions of Section 7.2 and Section 7.4, Seller shall be obligated to adjust the Purchase Price to account for Title Defects only to the extent the aggregate Title Defect Value of all Title Defects for which the Purchase Price would otherwise be reduced (the “Aggregate Title Defect Value”) exceeds a deductible (not a threshold) equal to 1.5% of the unadjusted Purchase Price. In addition, if the Title Defect Value for any single Asset is less than $50,000 (the “De Minimis Title Defect Cost”), such value shall not be considered in calculating the Aggregate Title Defect Value and no adjustment shall be made to the Purchase Price on account of De Minimis Title Defect Costs. The aggregated Title Defect Value(s) for any Asset shall never exceed the Allocated Value of such Asset.

Section 7.6 Interest Additions.

(a) If Seller discovers an increase in the Net Revenue Interest shown on Exhibit B with respect to an Asset that is free of Title Defects (an “Interest Addition”), then Seller shall, from time to time and without limitation, have the right to give Buyer written notice of such Interest Additions (an “Interest Addition Notice”), as soon as practicable but not later than the Defect Notice Time, stating with reasonable specificity the Asset affected, the particular Interest Addition claimed, and Seller’s good faith estimate of the amount the additional interest increases the value of the affected Asset over and above that Asset’s Allocated Value (the “Interest Addition Value”).

(b) The Interest Addition Value shall be determined by multiplying the Allocated Value of the subject Well (or the specified zone(s) therein) by a fraction, the numerator of which is the increase in the Net Revenue Interest in such Well (or the specified zone(s) therein) over the Net Revenue Interest specified therefor in Exhibit B, and the denominator of which is the Net Revenue Interest specified for such Well (or the specified zone(s) therein) in Exhibit B. Seller shall conclusively be deemed to have waived any additional interest not asserted by an Interest Addition Notice on or before the Defect Notice Time.

(c) If Buyer agrees with the existence of the Interest Addition and Seller’s good faith estimate of the Interest Addition Value, then the Purchase Price shall be increased by the amount of the Interest Addition Value. If Buyer contests in good faith the existence of the Interest Addition or Seller’s good faith estimate of the Interest Addition Value, then Buyer shall so notify Seller in writing on or before the date that is four Business Days before the Closing Date (an “Interest Addition Rejection Notice”), which Interest Addition Rejection Notice shall state with reasonable specificity the basis of Buyer’s rejection of the Additional Interest or of such Interest Addition Value. For any Interest Addition asserted by Seller in an Interest Addition Notice by the Defect Notice Time, if Buyer fails to timely deliver an Interest Addition Rejection Notice, Buyer shall be deemed to have accepted the validity of such Interest Addition and such Interest Addition Value, (subject to Section 7.6(d)) the Purchase Price shall be increased by an amount equal to such Interest Addition Value. If Buyer timely delivers an Interest Addition Rejection Notice with respect to any Interest Addition, then representatives of the Parties, knowledgeable in title matters shall promptly (but in any event at least two Business Days before the Closing Date) meet and attempt to agree on whether such

Interest Addition exists and, if so, the Interest Addition Value applicable thereto.

ARTICLE 8

ENVIRONMENTAL DEFECTS

Section 8.1 Buyer’s Environmental Assessment. Beginning on the date of this Agreement and ending at the Defect Notice Time, Buyer shall have the right, at its sole cost, risk, and expense, to conduct an environmental assessment of the Assets. During Seller’s regular hours of business and after providing Seller and the applicable Company Entity with written notice of any such activities no less than one Business Day in advance (which written notice shall include the identity of the operator (if other than Seller or a Company Entity) and any other third party whose permission is legally required, which permission Seller or the applicable Company Entity shall use commercially reasonable efforts to promptly obtain, it being understood that access will not be provided unless and until such permission is obtained), Buyer and its representatives shall be permitted to enter upon the Assets, inspect the same, review all of Seller’s and the Company Entity’s files and records (other than those for which Seller or the Company Entity has an attorney-client privilege) relating to the Assets, and generally conduct visual, non-invasive tests, examinations, and investigations. No sampling or other invasive inspections of the Assets may be conducted without Seller’s prior written consent, which shall not be unreasonably withheld. Seller will have the right to (a) observe such investigation, (b) promptly receive a copy of any final environmental report received by Buyer with respect to the Assets and (c) at Seller’s request, promptly receive a copy of any other reports, summaries and other information created or delivered in conjunction with Buyer’s environmental assessment and any supporting documents, in each case, in the possession of Buyer relating to Properties with respect to which an Environmental Defect Notice has been delivered. All information obtained or reviewed by Buyer shall be maintained as confidential by Buyer through the Closing, unless disclosure is required by any Governmental Authority or pursuant to Law.

Section 8.2 Environmental Defects. Buyer shall notify Seller in writing of any Environmental Defect (an “Environmental Defect Notice”) no later than the Defect Notice Time. The Environmental Defect Notice shall include: (i) the Asset(s) affected; (ii) a complete and reasonably detailed description of the alleged Environmental Defect; (iii) Buyer’s good faith estimate of the cost of Remediation or investigation of such Environmental Defect (the “Environmental Defect Value”); and (iv) appropriate documentation substantiating Buyer’s claim. From the date hereof through the Defect Notice Time, the Parties will use good faith

commercially reasonable efforts to meet biweekly, whether in person or via conference call, to discuss the status of Buyer’s Environmental Defect review. If Seller notifies Buyer in good faith that Seller is unclear which Environmental Law is violated or requires Remediation with respect to any asserted Environmental Defect, Buyer will reasonably promptly thereafter specify the same in writing.

Section 8.3 Seller’s Right to Remediate. Seller shall have the right, but not the obligation, to attempt (at Seller’s (and not the Company Entities’) sole cost) to Remediate any alleged Environmental Defect at any time before Closing. Seller will be deemed to have adequately completed the Remediation upon receipt of a certificate or approval from the applicable Governmental Authority that the Remediation has been implemented to the extent necessary to comply with existing Laws or Buyer’s approval of the Remediation (which may be granted or withheld in Buyer’s sole discretion).

Section 8.4 Remedies for Environmental Defects. For any Environmental Defect asserted in an Environmental Defect Notice and not Remediated before Closing (and subject to Seller’s right to contest the existence of any Environmental Defect or the amount of any Environmental Defect Value as set forth in Section 8.5), subject to Section 8.6, the Purchase Price shall be reduced by the Environmental Defect Value for such Environmental Defect.

Section 8.5 Contested Environmental Defects. With respect to any Environmental Defect timely asserted by an Environmental Defect Notice not waived in writing by Buyer or Remediated before Closing, if Seller contests in good faith the existence of such Environmental Defect or Buyer’s good faith estimate of the Environmental Defect Value, then Seller shall so notify Buyer in writing no later than the earlier of (i) 10 Business Days after Buyer’s delivery to Seller of such Environmental Defect Notice or (ii) September 20, 2013 (an “Environmental Defect Rejection Notice”), which Environmental Defect Rejection Notice shall state with reasonable specificity the basis of Seller’s rejection of the Environmental Defect or of Buyer’s good faith estimate of the Environmental Defect Value. For any Environmental Defect asserted by Buyer in an Environmental Title Defect Notice by the Defect Notice Time, if Seller fails to timely deliver an Environmental Defect Rejection Notice, then Seller shall be deemed to have accepted the validity of such Environmental Defect and such Environmental Defect Value, and (subject to Sections 8.4 and 8.6) the Purchase Price shall be reduced by an amount equal to such Environmental Defect Value unless such Environmental Defect is Remediated before Closing, as provided in Section 8.3. If Seller timely delivers an Environmental Defect Rejection Notice with respect to any Environmental Defect, then representatives of the Parties, knowledgeable in environmental matters, shall promptly (but in any event no later than five Business Days after delivery of the Environmental Defect Rejection Notice) meet and attempt to agree on whether such alleged Environmental Defect exists and, if so, the Environmental Defect Value applicable thereto. If the Parties are unable to reach agreement with respect to any Environmental Defects, the Environmental Defect or the Environmental Defect Value subject to the Environmental Defect Rejection Notice shall be submitted to arbitration in accordance with the procedures set forth in Section 8.8.

Section 8.6 Limitation. Notwithstanding the other provisions of this Article 8, no adjustment to the Purchase Price for Environmental Defect Values shall be made unless and until the aggregate value of all Environmental Defect Values for which the Purchase Price would

otherwise be reduced (the “Aggregate Environmental Defect Value”) exceeds a deductible (not a threshold) equal to 1.5% of the unadjusted Purchase Price. If the Environmental Defect Value with respect to any single Environmental Defect is less than $50,000 (the “De Minimis Environmental Defect Cost”), such cost shall not be considered in calculating the Aggregate Environmental Defect Value and no adjustment to the Purchase Price shall be made on account of De Minimis Environmental Defect Costs.

Section 8.7 Exclusive Remedies. The rights and remedies expressly granted to Buyer in or pursuant to this Agreement are the exclusive rights and remedies against Seller related to any Environmental Defect or Title Defect with respect to the Properties, or losses related thereto.

Section 8.8 Limited Arbitration. It is agreed, as a severable and independent arbitration agreement separately enforceable from the remainder of this Agreement, that all disputes under Article 7 or Article 8 shall be finally and exclusively submitted to, and determined by, binding arbitration. The arbitration proceedings shall be held in Houston, Texas. The arbitration shall be conducted before a single arbitrator (who shall be selected by mutual agreement of the Parties) pursuant to the then current Commercial Arbitration Rules of the American Arbitration Association (the “AAA”); provided, however, that if disputes exist with respect to both title and environmental matters, and the Parties cannot agree on a single arbitrator with experience in both such matters, the Parties agree to conduct separate arbitration proceedings with the title disputes and environmental disputes being submitted to separate arbitrators. If the Parties are unable to agree on any arbitrator, the Houston office of the AAA shall select the arbitrator. No arbitrator shall be selected who has had an affiliation with either Party or any Affiliate of either Party within the five year period preceding the arbitration, or has any financial interest in the dispute, controversy, or claim. Each arbitrator must be a licensed and practicing attorney (including any attorney practicing in-house for a company, with an outside law firm, as a solo practitioner, or as a professional arbitrator) or a retired judge of a state or federal court. If any arbitrator should die, withdraw, or otherwise become incapable of serving, or refuse to serve, a successor arbitrator shall be selected and appointed in the same manner as the original arbitrator. In the event of any conflict between the Commercial Arbitration Rules of the AAA and the provisions of this Section 8.8, the provisions of this Section 8.8 shall govern and control. Each arbitrator shall apply the laws of the State of Texas (without regard to conflict of law rules) to the dispute, controversy, or claim except to the extent the subject matter of the dispute, controversy, or claim is governed by the laws of another jurisdiction. With respect to each matter submitted to the arbitrator pursuant to this Section 8.8, the arbitrator must resolve such matter by choosing one Party’s proposed resolution, and may not resolve such matter in any other manner. To the extent that they are not inconsistent with the Commercial Arbitration Rules of the AAA, evidentiary questions shall be governed by the Texas Rules of Evidence. Any arbitration shall proceed in the absence of a Party who, after due notice, fails to answer or appear; provided, however, that an award shall not be made solely on the default of a Party, but the arbitrator shall require the Party who is present to submit such evidence as the arbitrator may determine is reasonably required to make an award. Each arbitrator’s award shall be in writing and shall set forth findings and conclusions upon which the arbitrator based the award. The prevailing Party in each arbitration shall be entitled to recover its reasonable attorneys’ fees, costs, and expenses incurred in connection with the arbitration, as determined by the arbitrator. Consequential, indirect, special, exemplary or punitive damages of a Party shall not be awarded under any circumstances. Any award pursuant to any arbitration

shall be final and binding upon the Parties. Notwithstanding anything in this Agreement to the contrary, Closing shall be delayed until no earlier than the third Business Day immediately following the day on which the last dispute is resolved pursuant to this Section 8.8. The Purchase Price at Closing shall be reduced by any Title Defect Value or Environmental Defect Value, and increased by any Interest Addition Value, awarded by the arbitrator, subject to the limitations set forth in Section 7.5, Section 7.6(d) or Section 8.6, as applicable, without duplication under Section 11.2.

Section 12.2 Effect of Termination. In the event that the Closing does not occur as a result of any Party exercising its right to terminate pursuant to Section 12.1, then except as set forth in Section 6.2, Article 1 and Article 15, this Agreement shall be null and void.

In the event that the claim for indemnification is based upon a claim by a Person other than the Indemnified Party (a “Third Party”) against the Indemnified Party, the Indemnified Party shall provide its notice of claim promptly after the Indemnified Party has actual knowledge of the Third Party claim and shall enclose a copy of all papers (if any) served with respect to the claim; provided, however, that failure to promptly provide such notice of claim shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is materially prejudiced by such delay or omission. In the event that a claim is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the notice of claim shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(b) The Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought by a Third Party against the Indemnified Party that are covered by the indemnification set forth in this Article 13. The Indemnifying Party shall have 30 days from its receipt of the notice of claim to notify the Indemnified Party whether or not it will assume control of the defense of such claim. If the Indemnifying Party elects to control the defense, it shall select counsel (provided that such counsel shall be reasonably acceptable to the Indemnified Parties), determine whether to appeal any decision of any court and (if it deems appropriate) settle any such matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the consent (which consent shall not be unreasonably withheld, conditioned or delayed) of the Indemnified Party unless it includes a full release of the Indemnified Party (and its applicable Affiliates) from such matter or issues, as the case may be. If the Indemnifying Party assumes control of the defense of any Third Party claim, the Indemnified Party agrees to cooperate fully with the Indemnifying Party with respect to all aspects of the defense of any claims covered by the indemnification set forth in Article 13, including the prompt furnishing to the

Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party (or its applicable Affiliate) may receive, permitting the names of the Indemnified Party (or its applicable Affiliates) to be utilized in connection with such defense, the making available to the Indemnifying Party of any files, records or other information of the Indemnified Party (or its applicable Affiliates) that Indemnifying Party reasonably consider relevant to such defense and the making available (upon reasonable request) to Indemnifying Party of any employees of the Indemnified Party (or its applicable Affiliate); provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and its applicable Affiliates) and further agrees to reasonably maintain the confidentiality of all files, records and other information furnished by the Indemnified Party (or its applicable Affiliates) pursuant to this Section 13.4. In no event shall the obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any claims covered by the indemnification set forth in this Article 13; provided, however, that the Indemnified Party may, at its option, cost and expense, hire and pay for counsel in connection with any such defense. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party reasonably informed as to the status of any such defense, but the Indemnifying Party shall have the right to retain sole control over such defense.

(c) If the Indemnifying Party does not elect to assume control of the defense within 30 days from its receipt of the notice of claim or fails to give notice that it will assume control of the defense, the Indemnified Party shall have the right to defend such claim with counsel of the Indemnified Party’s choosing (provided such counsel shall be reasonably acceptable to the Indemnifying Party); provided, however, that the Indemnified Party shall not enter into any settlement or compromise or make any admission or acknowledgment that would give rise to Losses to be assumed by the Indemnifying Party without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed).

(d) In determining the amount of any Losses for which the Indemnified Parties are entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Parties, and such correlative insurance benefit shall be net of any incremental insurance premium that becomes due and payable by the Indemnified Party (or its applicable Affiliates) as a result of such claim, and (ii) all amounts recovered by the Indemnified Party (and its applicable Affiliates) under contractual indemnities from third parties. The Indemnified Party hereby agree to use commercially reasonable efforts to realize any applicable insurance proceeds and amounts recoverable under such contractual indemnities; provided, however, that the reasonable costs and expenses (including court costs and reasonable attorneys’, accountants’, and experts’ fees) of the Indemnified Party (and its applicable Affiliates) in connection with such efforts shall reduce the reduction of the gross amount of the indemnification based upon such insurance proceeds or contractual indemnities. To the extent that the Indemnifying Party has made any indemnification payment hereunder in respect of a claim for which the

Indemnified Party has asserted a related claim for insurance proceeds or under a contractual indemnity, the Indemnifying Party shall be subrogated to the rights of the Indemnified Party to receive the proceeds of such insurance or contractual indemnity.

Section 13.5 Exclusive Remedy. Each Party acknowledges and agrees that its sole and exclusive remedy with respect to any Losses pursuant to or in connection with this Agreement shall be limited to the indemnification provisions of this Agreement, other than with respect to Losses arising from fraud by or on behalf of a Party in connection with this Agreement, and if the Closing occurs each Party releases, remises and forever discharges the other Party and its Affiliates and all the officers, directors, employees, agents, advisors and representatives of the other Party or any of its Affiliates 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 such parties might now or subsequently may have, based on, relating to or arising out of this Agreement, the ownership, use or operation of the Assets, or the condition, quality, status or nature of the Assets, breaches of statutory or implied warranties, nuisance or other tort actions, rights to punitive damages and common law rights of contribution, rights under agreements between Seller or any of its Affiliates, and rights under insurance maintained by a Seller or any of its Affiliates (INCLUDING THOSE CLAIMS RESULTING FROM THE SOLE, JOINT OR CONCURRENT NEGLIGENCE (BUT NOT GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), STRICT LIABILITY OR OTHER LEGAL FAULT OF SELLER OR ANY COMPANY ENTITY OR ANY REPRESENTATIVES OF SELLER OR ANY COMPANY ENTITY) OTHER THAN THOSE ARISING UNDER THE INDEMNIFICATION PROVISIONS OF THIS AGREEMENT AND UNDER THE COVENANTS OF THIS AGREEMENT CONTEMPLATED TO BE COMPLIED WITH AFTER CLOSING. EXCEPT FOR THE RIGHTS OF BUYER FOR A BREACH OF SECTION 4.28 OF THIS AGREEMENT AND THE RIGHTS OF BUYER UNDER ARTICLE 8 OF THIS AGREEMENT, IF THE CLOSING OCCURS BUYER EXPRESSLY AND KNOWINGLY WAIVES ANY AND ALL OTHER RIGHTS AND REMEDIES IT MAY HAVE AGAINST SELLER WITH RESPECT TO ANY ENVIRONMENTAL MATTER RELATING TO THE ASSETS (INCLUDING (I) ANY ENVIRONMENTAL DEFECT, (II) THE ENVIRONMENTAL CONDITIONS OF THE ASSETS, (III) THE RELEASE, TRANSPORTATION OR DISPOSAL OF HAZARDOUS MATERIALS OR (IV) VIOLATIONS OF ENVIRONMENTAL LAW, INCLUDING COMMON LAW AND STATUTORY REMEDIES (INCLUDING STRICT LIABILITY CLAIMS AND REMEDIES UNDER CERCLA AND ANY OTHER ENVIRONMENTAL LAW).

Section 13.6 Buyer Remedies.

(a) Buyer’s sole and exclusive remedies for Seller’s indemnity obligations under Section 13.2(c) shall be Buyer’s right to satisfy claims with respect to such obligations from the Indemnity Escrow Amount; provided, however, that except for obligations arising out of matters for which Buyer timely delivered notice pursuant to Section 13.4 before the first anniversary of the Closing Date, Buyer shall have no right to receive any amount from the Indemnity Escrow Amount after the first anniversary of the Closing Date to satisfy Seller’s indemnity obligations under Section 13.2(c).

(b) The Parties agree that no portion of the Indemnity Escrow Amount shall be withdrawn from the Escrow Account prior to the first anniversary of the Closing except to satisfy Obligations of Seller under this Article 13, (ii) each Party agrees to provide instructions to the Escrow Agent consistent with the provisions of this Article 13 and not otherwise, and (iii) the Parties shall issue such joint written instructions to the Escrow Agent in accordance with the terms of the Escrow Agreement as may be necessary to disburse portions of the Indemnity Escrow Amount to Buyer to satisfy indemnity claims of the Buyer Indemnitees pursuant to this Agreement, and shall not act in bad faith with respect to, or otherwise unreasonably withhold, the issuance of any such joint written instruction.

(c) For federal and state income Tax purposes, Buyer and Seller agree to treat the Indemnity Escrow Amount in accordance with Proposed Treasury Regulation Section 1.468B-8 (February 1, 1999). Accordingly, prior to the date of the release of funds to Seller, Buyer shall be treated as the owner of the Indemnity Escrow Amount and thus shall take into account in filing its income Tax Returns all items of income, gain, loss and deduction with respect to the Indemnity Escrow Amount in accordance with Proposed Treasury Regulation Section 1.468B-8(c). From and after such date, Buyer and Seller shall (i) be treated for Tax purposes as the owners of their respective shares of the Indemnity Escrow Amount distributable to each, (ii) provide notice of such amounts to the Indemnity Escrow Agent in accordance with Proposed Treasury Regulation Section 1.468B-8(f) (or by such substitute method as may be required by the Indemnity Escrow Agent) , and (iii) take into account in filing its income Tax Returns its share of the items of income, gain, loss and deduction with respect to the Indemnity Escrow Amount in accordance with Proposed Treasury Regulation Section 1.468B-8(e). Any amount distributed from the Indemnity Escrow Account to Seller shall be treated as a payment pursuant to Buyer’s obligation to Seller arising from Seller’s sale of property to which the installment sale provisions of Section 453 of the Code, and the unstated interest provisions of Section 483 or 1274 of the Code, apply. For this purpose, Buyer shall provide to the Indemnity Escrow Agent, at the time of any disbursement, a schedule indicating the allocation of such disbursement from the Indemnity Escrow Account between (i) principal and (ii) imputed interest to be reported on IRS Form 1099-INT or 1099-OID. Neither Buyer nor Seller shall take any position for federal or state income Tax purposes that is inconsistent with the provisions of this Section 13.6(c).

Seller shall have the right during such period to make copies of the Documents at its expense.

Section 15.3 Entire Agreement. This Agreement and the Exhibits and Schedules attached hereto, as well as the Assignment, the Escrow Agreement, and the other documents executed and delivered in connection herewith, constitute the entire agreement between 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.

Except as provided in Section 6.8, Section 13.1 and Section 13.2, nothing in this Agreement shall provide any benefit to any third Person or entitle any third Person to any claim, cause of action, remedy or right of any kind, it being the intent of the Parties that this Agreement shall otherwise not be construed as a third Person beneficiary contract. Except as set forth in Section 6.8, the provisions of this Agreement are enforceable solely by the Parties (including any permitted assignee), and no limited partner of the sole member of Buyer, or any other Person, shall have the right, separate and apart from the Parties hereto, to enforce any provision of this Agreement or to compel any Party to comply with the terms of this Agreement.

Any assignment by any Party as permitted hereby shall not relieve such Party from any Liability hereunder.

Section 15.9 Governing Law; Venue. This Agreement, other documents delivered pursuant hereto and the legal relations between the Parties shall be governed by and construed and enforced in accordance with the laws of the State of Texas, without giving effect to principles of conflicts of law that would result in the application of the laws of another jurisdiction.
