As soon as practicable, and in any event within 30 days after receipt of the Final Settlement Statement, Buyer shall return to Seller a written report containing any proposed changes to the Final Settlement Statement and an explanation of any such changes and the reasons therefor (the “Dispute Notice”). Buyer’s failure to deliver to Seller a Dispute Notice detailing proposed changes to any of the adjustments in the Final Settlement Statement by such date shall be deemed to be an acceptance by Buyer of the adjustments set forth in the Final Settlement Statement delivered by Seller and any further changes to any of the adjustments set forth in the Final Settlement Statement shall be deemed waived by Buyer, and Seller’s determinations with respect to all such adjustments in the Final Settlement Statement shall prevail. If Buyer does deliver a Dispute Notice then, except for the adjustment changes raised by Buyer in such Dispute Notice, all other changes to any of the adjustments set forth in the Final Settlement Statement shall be deemed waived by Buyer, and Seller’s determinations with respect to all such adjustments in the Final Settlement Statement shall prevail. If the final Purchase Price less the Defect Cure Escrow Amounts set forth in the Final Settlement Statement is mutually agreed upon by Seller and Buyer or deemed agreed pursuant to the foregoing (or determined by the Accounting Arbitrator pursuant to Section 3.7), the Final Settlement Statement and such final Adjusted Purchase Price, less the Defect Cure Escrow Amounts (the “Final Price”), shall be final and binding on the Parties. Any difference in the Adjusted Purchase Price (less the Defect Cure Escrow Amounts) as paid at Closing pursuant to the Preliminary Settlement Statement and the Final Price shall be paid by the owing Party (which, if due by Buyer, SN shall notify Seller in writing of the amount of such difference owed by each Buyer Party based on such Buyer Party’s Proportionate Share and the portion of the Assets acquired by such Buyer Party), and on or before the date that is 10 days following agreement or deemed agreement (or determination by the Accounting Arbitrator, as applicable) (such date, the “Final Payment Date”) to the owed Party (which, if owed to Buyer, SN shall notify Seller in writing of the amount of such difference to be paid to each Buyer Party based on such Buyer Party’s Proportionate Share and the portion of the Assets acquired by such Buyer Party).

an alternative Accounting Arbitrator, then the Houston office of the AAA shall choose such Accounting Arbitrator (Grant Thornton LLP or such other Person agreed to by the Parties or chosen by the AAA, the “Accounting Arbitrator”), together with the Dispute Notice, the Final Settlement Statement and any other documentation such Party may desire to submit. Within 20 Business Days after receiving the Parties’ respective submissions, the Accounting Arbitrator shall render a decision choosing either Seller’s position or Buyer’s position with respect to each matter addressed in any Dispute Notice, based on the materials described above. Any decision rendered by the Accounting Arbitrator pursuant hereto shall be final, conclusive and binding on Seller and Buyer and will be enforceable against any of the Parties in any court of competent jurisdiction. The costs of such Accounting Arbitrators shall be borne one-half by Buyer and one-half by Seller.

3.8 Allocation of Purchase Price / Allocated Values. Buyer and Seller agree that the unadjusted Purchase Price shall be allocated among the Assets as set forth in Exhibit A-1 and Exhibit A-2, as applicable. The “Allocated Value” for any Asset equals the portion of the unadjusted Purchase Price allocated to such Asset in Exhibit A-1 or Exhibit A-2, as applicable, and such Allocated Value shall be used in calculating adjustments to the Purchase Price as provided herein. Buyer and Seller also agree (a) that the Allocated Values, as adjusted, shall be used by Seller and Buyer as the basis for reporting asset values and other items for purposes of this Section 3.8, and (b) that neither they nor their Affiliates will take positions inconsistent with such Allocated Values in notices to Governmental Authorities, in notices to Preferential Purchase Right holders or in other documents or notices relating to the transactions contemplated by this Agreement.

If the Parties reach an agreement with respect to such allocation (as agreed, the “Tax Allocation”), (i) the Parties shall update the Tax Allocation in a manner consistent with Section 1060 of the Code following any adjustment to the Purchase Price pursuant to this Agreement, and (ii) Seller and Buyer shall, and shall cause their Affiliates to, report consistently with the Tax Allocation on all Tax Returns (including Internal Revenue Service Form 8594 (Asset Acquisition Statement under Section 1060), which Form will be timely filed, if applicable, separately by Seller and Buyer with the Internal Revenue Service pursuant to the requirements of Section 1060(b) of the Code), and neither Seller nor Buyer shall take any position in any Tax Return that is inconsistent with the Tax Allocation unless otherwise required by applicable Law; provided, however, that neither Party shall be unreasonably impeded in its ability and discretion to negotiate, compromise and/or settle any Tax audit, claim or similar proceedings in connection with such allocation.

The Indemnified Party is authorized, prior to and during such 30 day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party.

(d) If the Indemnifying Party admits its Indemnity Obligations, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Claim.

If the Indemnifying Party has not yet admitted its Indemnity Obligations for a Claim, then the Indemnified Party shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for 10 Business Days following receipt of such notice to (i) admit in writing its Indemnity Obligations for the Claim and, if its Indemnity Obligations are so admitted, reject, in its reasonable judgment, the proposed settlement, or (ii) deny liability for such Claim; provided that if the Indemnifying Party does not notify the Indemnified Party within such 10 Business Day period, then the Indemnifying Party shall be deemed to be denying its liability for such Claim and, in the event of a denial of liability for such Claim, then the Indemnified Party may enter into such proposed settlement on the terms disclosed to the Indemnifying Party without the Indemnifying Party’s consent.

(f) In the case of a claim under Section 8.2, Section 8.3, Section 8.4, Section 8.5, Section 11.7(c), Section 12.1(c) or Section 13.4(c) (in each case) that is not based upon a Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim Notice to (i) cure the Liabilities complained of, (ii) admit its Indemnity Obligations for such Liability or (iii) dispute the claim for such Liabilities.

(e) With respect to any AFE or similar request received by Seller that is estimated to cost in excess of $500,000 Seller shall forward such AFE to Buyer as soon as is reasonably practicable and thereafter the Parties shall consult with each other regarding whether or not Seller should elect to participate in such operation. Buyer agrees that it will (i) timely respond to any written request for consent pursuant to this Section 11.1(e) and Section 11.1(b)(iii), and (ii) consent to any written request for approval of any AFE or similar request that Buyer reasonably considers to be economically viable. In the event the Parties are unable to agree within ten days (unless a shorter time, not to be less than 48 hours, is reasonably required by the circumstances and the applicable joint operating agreement and such shorter time is specified in Seller’s request for consent) of Buyer’s receipt of any consent request as to whether or not Seller should elect to participate in such operation, Seller’s decision shall control and such operation shall be deemed to have been consented to by Buyer.

11.2 HSR Act. If applicable, within 10 Business Days following the execution by Buyer and Seller of this Agreement, Buyer and Seller will each prepare and simultaneously file with the DOJ and the FTC the notification and report form required for the transactions contemplated by this Agreement by the HSR Act and request early termination of the waiting period thereunder. Buyer and Seller agree to respond promptly to any inquiries from the DOJ or the FTC concerning such filings and to comply in all material respects with the filing requirements of the HSR Act. Buyer and Seller shall cooperate with each other and, subject to the terms of the Confidentiality Agreement, shall promptly furnish all information to the other Party that is necessary in connection with Buyer’s and Seller’s compliance with the HSR Act. Buyer and Seller shall keep each other fully advised with respect to any requests from or communications with the DOJ or FTC concerning such filings and shall consult with each other with respect to all responses thereto. Each of Seller and Buyer shall use its reasonable efforts to take all actions reasonably necessary and appropriate in connection with any HSR Act filing to consummate the transactions consummated hereby.

11.3 Governmental Bonds. Buyer acknowledges that none of the bonds, letters of credit and guarantees, if any, posted by Seller or its Affiliates with Governmental Authorities and

relating to the Assets are transferable to Buyer. On or before the Closing Date, Buyer shall obtain replacements for those bonds, letters of credit and guarantees described on Schedule 11.3, to the extent such replacements are necessary for Buyer’s ownership of the Assets and Buyer shall use its reasonable efforts to cause the cancellation of such bonds, letters of credit and guarantees effective as of the Closing Date. In addition, at or prior to Closing, Buyer shall deliver to Seller evidence of the posting of bonds or other security with all applicable Governmental Authorities meeting the requirements of such authorities to own and, where appropriate, operate, the Assets.

11.4 Record Retention. Buyer, for a period of 7 years following the Closing, will (a) retain the Records, (b) provide Seller, its Affiliates and its and their officers, employees and representatives with access to the Records (to the extent that Seller has not retained the original or a copy) during normal business hours for review and copying at Seller’s expense, and (c) provide Seller, its Affiliates and its and their officers, employees and representatives with access, during normal business hours, to materials received or produced after the Closing relating to any indemnity claim made under Section 8.2 for review and copying at Seller’s expense.

11.5 [Intentionally Omitted.]

11.6 Non-Solicitation; No-Hire. Prior to the first anniversary of the Closing Date, neither Buyer nor any of its Affiliates shall hire, retain or attempt to hire or retain any employee of Seller or in any way interfere with the relationship between Seller and any of its employees, other than the Available Employees; provided, that the non-solicitation restriction in this Section 11.6 shall not apply in the event an employee of Seller, other than an Available Employee, contacts Buyer (or any of its Affiliates) regarding employment in response to an advertisement identifying employment opportunities published by Buyer (or any of its Affiliates) in a newspaper of general circulation or on its web site or if an employee of Seller contacts Buyer (or any of its Affiliates) without having been directly solicited by Buyer, an Affiliate of Buyer, or representative of either. Buyer shall be permitted to contact any of Seller’s independent contractors whose services relate to the Assets to discuss post-Closing services. With regard to post-Closing hiring of Available Employees, Section 11.7(a) shall govern.

11.7 Employee Matters.

(a) Offers of Employment. Schedule 11.7(a) contains a list of the name, location and job title of employees of Seller or its Affiliates whose jobs relate to the Assets at the area superintendent level or below and who are available for hire by Buyer (the “Available Employees”). Seller shall provide a benefits booklet to Buyer of benefits commonly provided to the Available Employees. From and after the Execution Date, and notwithstanding the Confidentiality Agreement, Buyer shall be permitted to meet with and interview the Available Employees in connection with prospective employment with Buyer or its Affiliates and offer employment to any such Available Employee on terms determined by Buyer in its sole discretion. Buyer is responsible for scheduling any meetings or interviews and Seller shall reasonably assist Buyer with respect to such scheduling. Any meetings or interviews between Buyer and the Available Employees shall be scheduled at times and places that are not unreasonably inconvenient or disruptive to Seller or its Affiliates, with reasonable advance notice being provided to Seller. It is understood that Buyer shall have no obligation to interview or make an offer of employment to any of the Available Employees pursuant to this Agreement or for any other reason. Any offers of employment by a Buyer Party to any of the

Available Employees shall be in writing (or an electronic document) with an identification of the employee’s salary or hourly rate, bonus opportunity, incentive compensation, and benefits. Buyer shall send to Seller, within five days after the last offer of employment is made, a schedule identifying each offer of employment that was made, whether such offer was for compensation greater than, less than or equal to the compensation currently being paid to such employee and whether such employee accepted such offer, and effective upon the expiration or termination of the Transition Services Agreement, Seller shall terminate the employment of each Available Employee (or cause the employment of each Available Employee to be terminated) if (i) Buyer has made an offer of employment to such Available Employee and (ii) such Available Employee has accepted such offer of employment (and confirmation thereof has been provided to Seller), (each such Available Employee who then becomes employed by Buyer as of the expiration or termination of the Transition Services Agreement shall be referred to herein as a “Transferred Employee”). Buyer shall make all offers of employment to Available Employees pursuant to this Section 11.7 at least ten days prior to the Closing, and such Available Employees must accept or decline such offers at least five days prior to the Closing, or else such employment offers shall be void. With regard to any Available Employee that is not offered employment by Buyer or declines any employment offered by Buyer as referenced in the preceding sentence, Buyer, Buyer’s Affiliates, and any vendor supplying workers to Buyer to provide services or labor relating to the Assets may not retain such Available Employee in an employment or other capacity for a period of one year after Closing, except as permitted under Section 11.6. For the avoidance of doubt, nothing in this Section 11.7 shall prohibit (A) Seller and its Affiliates from retaining any Available Employees who do not receive offers from Buyer or reject their offers from Buyer and (B) Seller and its Affiliates from attempting to induce any Available Employees to continue their employment with Seller or its Affiliates, as applicable. Buyer hereby agrees that it will comply with all applicable Laws in making any employment decisions and taking any actions pursuant to this Section 11.7.

(b) Responsibility of the Parties. Except for Liabilities for which Buyer is expressly responsible under the terms of the Transition Services Agreement and/or the Marketing Transition Services Agreement, Seller and its Affiliates shall retain all Liabilities relating to or arising from the employment of any Available Employee by Seller or its Affiliates on or before the termination of their employment relationships by Seller or its Affiliates (the “Retained Employee Liabilities”). Each Buyer Party shall be responsible for all Liabilities relating to or arising during the period of such Buyer Party’s employment of any Transferred Employees (the “Buyer Employee Liabilities”).

(c) Buyer’s Obligations. Each Buyer Party shall be responsible for all Liabilities relating to or arising during the period of such Buyer Party’s employment of any current or former employees of Seller. Seller and its Affiliates shall not assume any such Liabilities pursuant to this Agreement or otherwise. The applicable Buyer Party shall be solely responsible for all such Liabilities and shall indemnify and hold Seller and its Affiliates harmless for and all Liabilities arising or relating to the employment by such Buyer Party of any current or former employees of Seller or its Affiliates after the Closing.

(d) WARN Act. Buyer shall be solely responsible for complying with the WARN Act and any and all obligations under other applicable Laws requiring notice of plant

closings, relocations, mass layoffs, reductions in force or similar actions (and for any failures to so comply), in any case, applicable to the Transferred Employees as a result of any action by Buyer and its Affiliates on or after to the Closing Date. Buyer shall indemnify and hold harmless Seller and its Affiliates against any and all Liabilities arising in connection with any failure to comply with the requirements of this Section 11.7(d).

(e) No Third Party Beneficiaries. The provisions of this Section 11.7 are solely for the benefit of the respective Parties to this Agreement and nothing in this Section 11.7, express or implied, shall confer upon any employee (or any dependent or beneficiary thereof), any rights or remedies, including any right to continuance of employment or any other service relationship with Buyer, Seller or any of their Affiliates, or any right to compensation or benefits of any nature or kind whatsoever under this Agreement. Further, the provisions of this Section 11.7 do not constitute the creation, amendment, or modification of any employee benefit plan (with the meaning of Section 3(3) of ERISA) of Seller or Buyer or any of their respective Affiliates.

11.8 Compliance With Tag Right. Seller, no later than two Business Days after the Execution Date, shall send to the holder of the Tag Right a notice seeking to obtain from such holder a written election as to whether such holder wishes to exercise the Tag Right with respect to its Tag Right Interests. If the holder of the Tag Right properly and timely exercises its right to sell its Tag Right Interests, Buyer shall purchase such Tag Right Interests (a) for the same proportionate Allocated Value as is allocated to Seller’s interest in such Assets, and (b) on the same proportionate terms as are set forth in this Agreement.

11.9 Hedging.

(a) From time to time between the Execution Date and Closing, a Buyer Hedging Party may deliver a written notice to Seller specifying any amounts such Buyer Hedging Party would like to be hedged pursuant to the hedging transactions generally described on Schedule 11.9(a), Part I and Schedule 11.9(a), Part II and not exceeding the aggregate volumes set forth on Schedule 11.9(a), Part I or the aggregate volumes set forth on Schedule 11.9(a), Part II for the applicable Buyer Hedging Party (collectively, the “Hedging Transactions”) for such Buyer Hedging Party identified on such schedule with the counterparties identified in such schedule (collectively, the “Counterparties”), and upon receipt of any such notice on a Business Day during normal business hours, Seller shall promptly (and in any event, within three Business Days), enter into the requested Hedging Transactions, provided that Seller does not have to any enter into any such Hedging Transaction unless (i) the applicable Counterparty or Counterparties identified in such request agree to the Hedging Transaction requested by such Buyer Hedging Party, (ii) each of the Counterparties in the documents evidencing any such Hedging Transaction will (A) permit the assignment by Seller to the applicable Buyer Hedging Party (and/or such Buyer Hedging Party’s designee identified on Schedule 11.9(a), provided that such notice designates that such Buyer Party’s designee will be the ultimate assignee of such Hedging Transaction) at the Closing of all of the trades that are the subject of any such Hedging Transaction and (B) release Seller from any and all obligations and liabilities related or attributable to any such Hedging Transactions upon such assignment; provided that, for the avoidance of doubt, if such Counterparties fail to release Seller as contemplated in this Section 11.9(a), in no event shall

any Buyer Hedging Party be relieved of any of its obligations under this Section 11.9, and (iii) such Buyer Hedging Party has executed or caused the execution of any documents, provided such cooperation, and taken or caused to be taken any other actions reasonably necessary to enable Seller to timely effectuate the entry into such Hedging Transactions. Contemporaneously with the execution of this Agreement, Buyer has caused BEP II and BCP VII to deliver to Seller an executed guaranty substantially in the form attached as Exhibit R (the “Blackstone Guaranty”), with respect to AcqCo’s payment obligations pursuant to Section 11.9(e).

(b) At the Closing, subject to Section 11.9(a), Seller shall assign to the applicable Buyer Hedging Party (or such Buyer Hedging Party’s designee identified on Schedule 11.9(a)) all of the trades that are the subject of the Hedging Transactions entered into by Seller for such Buyer Hedging Party (or such Buyer Hedging Party’s designee identified on Schedule 11.9(a)) pursuant to this Section 11.9 and such Buyer Hedging Party (or such Buyer Hedging Party’s designee identified on Schedule 11.9(a)) shall accept such assignment from Seller and assume all obligations and liabilities attributable thereto pursuant to all documentation required by the applicable Counterparties.

(c) In the event that any Counterparty terminates any of its Hedging Transactions, the Buyer Hedging Party for whom such Hedging Transaction was entered into by Seller shall be obligated for, and shall promptly pay to Seller, all Hedging Losses resulting from or attributable to such Hedging Transactions and the termination thereof.

(d) Except upon the termination of this Agreement as contemplated by Section 7.2(b), within five Business Days following the termination of this Agreement in accordance with Article VII by Buyer or Seller, as the case may be, Seller shall unwind all Hedging Transactions with each Counterparty and the Buyer Hedging Party shall be obligated for, and shall promptly pay to Seller, all Hedging Losses resulting from or attributable to the Hedging Transactions for which Seller entered into for such Buyer Hedging Party and the unwind thereof.

(e) Whether or not the Closing occurs, except upon the termination of this Agreement as contemplated by Section 7.2(b), the applicable Buyer Hedging Party shall pay, be responsible for, release, defend, indemnify and hold Seller and its Affiliates harmless from and against any and all Hedging Losses for which such Buyer Hedging Party is responsible pursuant to this Section 11.9 (the “Hedging Indemnities”).

(f) Notwithstanding anything to the contrary in this Agreement, the Hedging Transactions and the underlying contracts and the actions to be taken by the Parties in accordance with this Section 11.9 are an exception to, and will under no circumstance constitute a breach of any of (1) the representations and warranties made by Seller in this Agreement or in any certificate to be delivered by Seller at Closing, and (2) Seller’s covenants contained in Section 11.1 or in any certificate to be delivered by Seller at Closing.

11.10 Financing.

(a) Each Buyer Party shall take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to arrange and consummate such Buyer Party’s portion of the Debt Financing (or any permitted replacement, amended, modified or any applicable Alternate Financing) on the terms (or on terms not materially less favorable to such Buyer Party, except as agreed to by Seller) and conditions described in such Buyer Party’s Debt Commitment Letters (including the flex provisions set forth in the applicable Fee Letters), including (i) maintaining in effect such Buyer Party’s Debt Commitment Letters, (ii) satisfying on a timely basis all terms, covenants and conditions set forth in such Buyer Party’s Debt Commitment Letters (including, to the extent the same are exercised, the flex provisions set forth in the applicable Fee Letters), (iii) entering into definitive agreements with respect thereto on the terms and conditions contemplated by such Buyer Party’s Debt Commitment Letters (or on terms not materially less favorable to such Buyer Party, taken as a whole, except as agreed to by Seller) (including, to the extent the same are exercised, the flex provisions set forth in the applicable Fee Letters) (iv) consummating such Buyer Party’s portion of the Debt Financing at or prior to Closing, (v) satisfying on a timely basis all Financing Conditions within the reasonable control of Buyer, (vi) drawing the full amount of the Financing required to consummate the Closing in the event that the Financing Conditions have been satisfied or, upon funding, would be satisfied and (vii) enforcing their rights under the Debt Commitment Letters, including through litigation pursued in good faith.

(b) Except with the prior written consent of Seller, each Buyer Party shall not permit any amendment, modification or waiver of its respective Debt Commitment Letters that (i) reduces the amount of aggregate cash proceeds available from the Debt Financing below the amount necessary to finance the transactions to be consummated on the Closing Date unless such Buyer Party obtains financing from alternative sources (including by increasing its portion of the Equity Financing) by a corresponding amount or (ii) imposes new or additional conditions to the receipt of the Debt Financing, in each of the cases of clauses (i) and (ii), in a manner that would reasonably be expected to delay or prevent the Closing (it being understood and agreed that each Buyer Party may, without the consent of the Seller, (A) amend or otherwise modify its respective Debt Commitment Letters to add lenders, lead arrangers, bookrunners, syndication agents or similar entities that have not executed such Debt Commitment Letters as of the date of this Agreement or (B) amend or modify its respective Debt Commitment Letters to implement the flex provisions set forth in their respective Fee Letters).

(c) From the date of the Agreement until the Closing, Seller shall provide, and shall use its commercially reasonable efforts to cause its Subsidiaries and its and their respective representatives to provide, reasonable cooperation in connection with the arrangement of the Debt Financing (or any permitted replacement, amendment or modification thereof or any Alternate Financing) as may be reasonably requested by a Buyer Party or its representatives (provided, that such requested cooperation does not unreasonably interfere with the ongoing business of Seller or any of the Affiliates), including:

(i) delivering to Buyer and each applicable Debt Financing Source that are parties to the Debt Commitment Letters the Required Financial Information on or before

the applicable deadlines set forth in Schedule 11.10(c) (for the avoidance of doubt, the delivery of such Required Financial Information on or before the applicable deadlines shall not be subject to any commercial reasonableness qualifier applicable to this Section 11.10(c));

(ii) cooperating, or causing its accountants to cooperate, with each applicable Buyer Party in its preparation of the pro forma financial statements required pursuant to such Buyer Party’s Debt Commitment Letters and any customary comfort letters related thereto (provided that, for the avoidance of doubt, Seller shall not be required to deliver or cause the delivery of any such comfort letter);

(iii) requesting any consents of accountants for use of their reports in any materials relating to the Debt Financing; and

(iv) solely with respect to the Assets, assisting each Buyer Party in connection with the preparation by such Buyer Party of pledge and security agreements and otherwise reasonably cooperating with each Buyer Party in facilitating the granting of security interest (and perfection thereof) in collateral, mortgages, other definitive financing documents or other certificates, in each case, as may reasonably be requested by Buyer in connection with the Debt Financing (provided that (A) none of the agreements, documents, instruments or certificates described in this clause (iv) shall be executed except in connection with the Closing, (B) the effectiveness thereof shall be conditioned upon, or become operative after, the occurrence of the Closing, and (C) the foregoing shall not require Seller or any of its Affiliates to take any action that would conflict with or violate any Law or subject Seller or its Affiliates to any Liability or any director, manager, officer or other employee of Seller or any of its Affiliates to any personal Liability);

it being understood and agreed that all materials and information obtained by each Buyer Party pursuant hereto may be shared with the Financing Sources; provided that this Section 11.10(c) shall not require travel or the obligation to incur any out-of-pocket Third Party costs by any of the subject Persons in order to comply with the terms hereof and that each applicable Buyer Party will make reasonable efforts to minimize any disruption associated with the cooperation contemplated by such Persons hereby. In each case, Seller’s cooperation pursuant to this Section 11.10(c) shall be at the Buyer’s written request with reasonable prior notice to Seller, and no such cooperation by Seller shall be required to the extent it could cause any representation or warranty in this Agreement to be breached, cause any condition to the Closing set forth in Article IV to fail to be satisfied or otherwise cause any breach of this Agreement.

Notwithstanding anything to the contrary herein, it is understood and agreed that (1) the condition precedent set forth in Section 4.2, as applied to Seller’s obligations under this Section 11.10(c), shall be deemed to be satisfied unless the Financing contemplated by the Debt Commitment Letters has not been obtained as a direct result of Seller’s Willful Breach of its obligations under this Section (other than Section 11.10(c)(i)); (2) such assistance shall not require Seller or any of its Affiliates to agree to any contractual obligation relating to the Financing that is not conditioned upon the Closing, that does not terminate without Liability to Seller or any of its Affiliates upon the termination of this Agreement or that would subject Seller or its Affiliates to any Liability; (3) in each case, Seller’s cooperation shall be at the Buyer Parties’ sole cost and expense, and on the Closing Date or following the termination of this

Agreement, the Buyer Parties shall promptly reimburse Seller for all documented out-of-pocket Third Party costs incurred by Seller or its Affiliates in connection with such cooperation; (4) the Buyer Parties shall indemnify and hold harmless Seller and its Affiliates and their respective directors, officers, employees and agents from and against any and all Liabilities by any such Persons suffered or incurred in connection with the Financing or any assistance or activities provided in connection therewith; (5) Seller shall have the right to review any presentations or other material written information prepared by any Buyer Party or its Affiliates prior to the dissemination of such materials to potential investors, lenders or other counterparties (other than to any of the GSO Investors, as defined in UnSub’s Debt Commitment Letter) to any proposed financing transaction (or filing with any Governmental Authority); (6) except to the extent disclosed to potential investors and lenders in connection with the Financing (who shall hold such confidential information confidential), all non-public or otherwise confidential information regarding Seller or the Assets obtained by any Buyer Party or their respective representatives shall be kept confidential in accordance with the Confidentiality Agreement; (7) Seller shall not be required to deliver or cause the delivery of any legal opinions or accountants’ comfort letters or reliance letters or make any representations in connection with the Financing; (8) the assistance described in this Section shall not require Seller to take any action that Seller reasonably believes could result in a violation of any material agreement or any confidentiality arrangement or the loss of any legal or other applicable privilege; and (9) Seller shall not be required to provide any information to Buyer or any Financing Source that is not then in the Seller’s or its Affiliates possession.

(d) Each Buyer Party shall use reasonable efforts to keep Seller reasonably informed with respect to material activity concerning the status of the Debt Financing contemplated by the Debt Commitment Letters. Without limiting the foregoing, each Buyer Party agrees to notify Seller promptly after obtaining knowledge thereof, if at any time (i) its Debt Commitment Letter shall expire or be terminated for any reason or (ii) any Debt Financing Source that is a party to its Debt Commitment Letter breaches, repudiates or threatens in writing to breach or repudiation of its Debt Commitment Letter or notifies such Buyer Party in writing that such Debt Financing Source no longer intends to provide financing to such Buyer Party on the terms set forth therein (or on terms not materially less favorable to such Buyer Party, taken as a whole, except as agreed to by Seller) (including, to the extent the same are exercised, the flex provisions set forth in the applicable Fee Letter), or (iii) for any reason such Buyer Party no longer believes in good faith that it will be able to obtain all or any portion of the Debt Financing contemplated by its Debt Commitment Letter on the terms described therein (or on terms not materially less favorable to such Buyer Party, taken as a whole, except as agreed to by Seller) (including, to the extent the same are exercised, the flex provisions set forth in the applicable Fee Letter), in each case to the extent such event would reasonably be expected to delay or prevent (or result in the delay or prevention of) the Closing. Each Buyer Party shall not, without the prior written consent of Seller, take or fail to take any action or enter into any transaction that would reasonably be expected to result in a failure of any conditions to obtaining the Debt Financing contemplated by the Debt Commitment Letters or any Alternate Financing contemplated by any New Debt Commitment Letters. Each Buyer Party shall not amend or alter, or agree to amend or alter, any Debt Commitment Letter in any manner that would prevent or materially impair or delay the consummation of the transactions contemplated hereby without the prior written consent of Seller.

(e) If any portion of the Debt Financing becomes unavailable on the terms and conditions (including the flex provisions set forth in the Fee Letters) contemplated in the Debt Commitment Letters (other than due to the breach by Seller of any representation, warranty or covenant contained herein or as a result of the failure of a condition contained herein to be satisfied by Seller), the applicable Buyer Party shall use its reasonable best efforts to arrange to obtain alternative financing from alternative sources in an amount sufficient to consummate the transactions contemplated hereunder (“Alternate Financing”) and, if obtained, will provide Seller with a correct and complete copy of, new financing commitment or commitments that provide for an amount sufficient to consummate the transactions contemplated hereunder and subject to the same (or no less favorable to Seller) Financing Conditions as the prior Debt Commitment Letter (the “New Debt Commitment Letter”). In the event an Alternate Financing is obtained (i) in full and a New Debt Commitment Letter is entered into, references in this Agreement to the applicable Debt Commitment Letter shall be deemed to refer to the applicable New Debt Commitment Letter or (ii) in part and a New Debt Commitment Letter is entered into, references in this Agreement to the applicable Debt Commitment Letter shall be deemed to include the applicable New Debt Commitment Letter and the applicable Debt Commitment Letter.

(f) The Buyer Parties shall not consent to any assignment of rights or obligations under the Debt Financing Commitment Letter without the prior written approval of Seller, such approval not to be unreasonably withheld. The Buyer Parties shall consult with and keep Seller informed in reasonable detail of the status of its efforts to arrange the Financing. None of the Buyer Parties nor any of their Affiliates shall take any action that would reasonably be expected to materially delay or prevent the consummation (subject to the terms and conditions hereof) of the transactions contemplated hereby, including the Financing.

(g) Subject to the terms and conditions of this Agreement and the applicable terms and conditions of the Equity Commitment Letters, each Buyer Party shall take (or cause to be taken) all actions and do (or cause to be done) all things necessary, proper or advisable to (i) obtain the portion of the Equity Financing contemplated by such Buyer Party’s Equity Commitment Letters simultaneously with the receipt of such Buyer Party’s portion of the Debt Financing, (ii) maintain in effect such Buyer Party’s Equity Commitment Letters, (iii) satisfy on a timely basis all conditions applicable to such Buyer Party as set forth in such Buyer Party’s Equity Commitment Letters that are within its control and (iv) consummate the portion of the Equity Financing contemplated by such Buyer Party’s Equity Commitment Letters at or prior to the Closing.

(h) Each Buyer Party shall not amend, alter or waive, or agree to amend, alter or waive (in any case whether by action or inaction), any term of its respective Equity Commitment Letters without the prior written consent of Seller that (i) reduces the amount of aggregate cash proceeds available from the Equity Financing below the amount necessary to finance the transactions to be consummated on the Closing Date unless such Buyer Party obtains financing from alternative sources by a corresponding amount or (ii) imposes new or additional conditions to the receipt of the Equity Financing, in each of the cases of clauses (i) and (ii), in a manner that would reasonably be expected to delay or prevent the Closing. Each Buyer Party shall promptly (and in any event within 2 Business Days) notify Seller of (A) the expiration or termination of its Equity Commitment Letter or (B) any refusal in writing by the

investors named in its Equity Commitment Letter to provide the full financing contemplated by such Equity Commitment Letter.

(ii) The SN Parties shall provide to Seller written notice within five Business Days after any SN Party discovers at any time that the SN Parties (collectively) do not have the Target Available Liquidity, and with the delivery of such notice, the SN Parties shall provide to Seller a letter of credit or surety bond for the benefit of Seller and in a form reasonably acceptable to Seller in an amount equal to the difference between the Target Available Liquidity and the SN Parties’ actual Available Liquidity. AcqCo shall provide to Seller written notice within five Business Days after AcqCo discovers at any time that AcqCo does not have the Target Available Liquidity, and with the delivery of such notice, AcqCo shall provide to Seller a letter of credit or surety bond for the benefit of Seller and in a form reasonably acceptable to Seller in an amount equal to the difference between the Target Available Liquidity and AcqCo’s actual Available Liquidity.

(iii) Each Buyer Party will provide an unaudited balance sheet prepared in the ordinary course of business and in accordance with GAAP on or before October 31, 2017 for the nine month period ended as of September 30, 2016. Thereafter, on or before April 30 of each calendar year after the Closing (beginning with the year 2018), each Buyer Party will provide audited financial statements prepared in the ordinary course of business and in accordance with GAAP, including a balance sheet, as of the end of and for the prior year. With such audited financial statements and additionally on or before October 31 of each calendar year after the Closing (beginning with the year 2017), each of the SN Parties (acting collectively), on the one hand, and AcqCo, on the other hand, shall provide to Seller (A) a written certification executed by an officer of such Buyer Parties or Buyer Party (as applicable) that such financial statements accurately present the financial condition of such Buyer Parties or Buyer Party (as applicable), (B) a report that contains evidence of the Available Liquidity of such Buyer Parties or Buyer Party (as applicable), (C) an accounting of the Wells that were producing as of the Closing Date that were plugged and abandoned after the Closing Date and (D) any changes to ownership status to any Assets due to a conveyance or assignment that alter the Party responsible for the Buyer Parties’ obligations under this Section 11.11. Each such report must be certified by an authorized officer of the applicable Buyer Parties or Buyer Party, as applicable, to be complete and correct in all material respects to the knowledge of such officer after reasonable inquiry.

(iv) If the SN Parties (acting collectively) cannot demonstrate that their Available Liquidity is at least equal to or greater than the Target Available Liquidity in connection with the bi-annual report delivered by such Parties pursuant to Section 11.11(a)(iii) above or if such Parties do not timely deliver all of the information required to be delivered to Seller by such Parties pursuant to such Section, then, on or before June 5 of the year in which such Available Liquidity was not demonstrated or such information was not timely provided, the SN Parties shall provide Seller with a letter of credit or a surety bond for the benefit of Seller and in a form reasonably acceptable to Seller in an amount equal to the difference between the Target Available Liquidity and the SN Parties’ collective actual Available Liquidity. If AcqCo cannot demonstrate that its Available Liquidity is at least equal to or greater than the Target Available Liquidity in connection with the bi-annual report delivered by AcqCo pursuant to Section 11.11(a)(iii) above or if AcqCo does not timely deliver all of the information required to be delivered to Seller by AcqCo pursuant to such Section, then, on or before June 5 of the year in which such Available Liquidity was not demonstrated or such information was not timely provided, AcqCo shall provide Seller with a letter of credit or a surety bond for the benefit of Seller and in a form reasonably acceptable to Seller in an amount equal to the difference between the Target Available Liquidity and AcqCo’s actual Available Liquidity.

(b) Each Buyer Party affirms that it will continue to follow an ongoing abandonment schedule and will act in good faith to maintain the operational and environmental stewardship achieved by Seller.

(c) If any Buyer Party sells, transfers or assigns all or any portion of the Assets acquired by such Buyer Party at Closing, such Buyer Party shall not be released from any portion of its obligations under this Section 11.11 without Seller’s prior written consent to such sale, transfer or assignment (which consent shall not be unreasonably withheld, conditioned or delayed); provided that Seller shall be deemed to have consented to such sale, transfer or assignment if (i) such acquiring Person has a credit rating equal to or higher than at least 2 of the following: Baa3 (or the equivalent) by Moody’s, BBB- (or the equivalent) by Standard & Poor’s or BBB- (or the equivalent) by Fitch or (ii) in the case of a sale, transfer or assignment by either of the SN Parties, on the one hand, or AcqCo, on the other hand, the acquiring Person provides to Seller a letter of credit or surety bond for the benefit of Seller and in a form reasonably acceptable to Seller in an amount equal to $50,000,000 multiplied by the Required Liquidity Ratio; and provided further any such transferee to whom Seller has consented, or is deemed to have consented, to in connection with such sale, transfer or assignment shall expressly assume such transferring Buyer Party’s obligations under this Section 11.11. The Parties acknowledge that any determination of whether a consent pursuant to this Section 11.11(c) is unreasonably withheld shall be without regard to the provisions of clause (ii) of the preceding sentence, it being understood that the ability of an acquiring Person to provide the letter of credit described in such clause (ii) does not constitute a requirement for Seller’s consent. Notwithstanding anything else in this Agreement to the contrary, the obligations set forth in this Section 11.11, including any related obligations that may be imposed upon a third party transferee of any of the Assets pursuant to this Section 11.11(c), shall terminate on the date that is twenty years after the Closing Date.

11.12 Successor Operator. While SN acknowledges that it desires to succeed each Seller as operator of those Assets or portions thereof that such Seller may presently operate,

SN acknowledges and agrees that Seller cannot and does not covenant or warrant that SN shall become successor operator of same since the Assets or portions thereof may be subject to operating or other agreements that control the appointment of a successor operator. Each Seller agrees, however, that as to the Assets it operates, it shall use its commercially reasonable efforts to support SN’s efforts to become successor operator (to the extent permitted under any applicable joint operating agreement) effective as of the Closing (at SN’s sole cost and expense and subject to the terms of Section 11.15 with respect to the Marketing Contracts) and to designate and/or appoint, to the extent legally possible, SN as successor operator effective as of the Closing (subject to the terms of Section 11.15 with respect to the Marketing Contracts).

11.13 NAESB Contracts. SN shall use its reasonable efforts to, on or before at least three days prior to the Transition Termination, enter into new NAESB Contracts or amend its existing NAESB Contracts, as applicable, with the counterparties to the NAESB Contracts (such counterparties, the “NAESB Contract Counterparties”, and such new or amended NAESB Contracts, the “SN NAESB Contracts”). Such SN NAESB Contracts shall (a) allow Seller to assign to SN the NAESB Contract Confirmations applicable to the corresponding NAESB Contracts, and (b) provide that Seller shall have no liability relating to matters arising after the Effective Time under such NAESB Contract Confirmations. Upon SN entering into any SN NAESB Contract Seller or its Affiliate (as applicable) shall, upon the Transition Termination but subject to the provisions of Schedule 13.4, assign to SN those NAESB Contract Confirmations related to such SN NAESB Contract.

11.14 Tax Treatment. Seller shall use commercially reasonable efforts, on or prior to the Closing Date, to (a) determine whether the Tax Partnership meets the eligibility requirements to make an election under Treasury Regulation § 1.761-2 to be excluded from the provisions of subchapter K of chapter 1 of the Code and (b), if the Tax Partnership meets such requirements, to cause the Tax Partnership to make such election effective prior to the Closing Date.

11.15 Assignment of Marketing Contracts. Upon termination of the Marketing Transition Services Agreement (the “Transition Termination”) but subject to the provisions of Schedule 13.4, the following documents will be delivered:

(a) Seller shall execute and deliver, and each of SN Parent and AcqCo shall execute and deliver, an assignment and assumption agreement of the gathering agreements set forth on Schedule 11.15(a) (the “Springfield Gathering Agreements”), substantially in the form of Exhibit H-1 (the “Springfield Gathering Assumption Agreement”), pursuant to which (i) Seller will assign all of its right, title and interest in and to the Springfield Gathering Agreements to SN Parent and AcqCo, and (ii) SN Parent and AcqCo will assume Seller’s obligations and liabilities under, and agree to be bound by, the Springfield Gathering Agreements.

(c) Seller shall cause AESC to execute and deliver, and SN shall execute and deliver, an assignment and assumption agreement of the Downstream Marketing Agreements, substantially in the form of Exhibit H-3 (the “Downstream Marketing Agreements Assumption Agreement”), pursuant to which (i) AESC and, if applicable Seller, will assign all of its right, title and interest in and to such Downstream Marketing Agreements to SN, and (ii) SN will assume AESC’s and, if applicable, Seller’s obligations and liabilities under, and agree to be bound by, such Downstream Marketing Agreements.

(d) Seller shall execute and deliver and each Buyer Party shall execute and deliver an assignment and assumption agreement of the gathering agreements set forth on Schedule 11.15(d) (the “Specified Gathering Agreements”), substantially in the form of Exhibit H-4 (the “Specified Gathering Assumption Agreement”, and collectively with the Springfield Gathering Assumption Agreement, the Specified Midstream Assumption Agreement and the Downstream Marketing Agreements Assumption Agreement, the “Assumption Agreements”), pursuant to which (i) Seller will assign all of its right, title and interest in and to the Specified Gathering Agreements to the Buyer Parties and (ii) the Buyer Parties will assume Seller’s obligations and liabilities under, and agree to be bound by, the Specified Gathering Agreements; provided that if the counterparties to the Specified Gathering Assumption Agreements so agree prior to the Transition Termination, then (x) Seller will assign all of its right, title and interest in and to the Specified Gathering Agreements to SN (or SN Parent, as agreed to by such counterparties) and AcqCo, and (y) to SN (or SN Parent, as agreed to by such counterparties) and AcqCo will assume Seller’s obligations and liabilities under, and agree to be bound by, the Specified Gathering Agreements.

(e) Seller shall deliver letters in lieu of transfer orders, prepared by Seller and in form reasonably satisfactory to SN, directing all purchasers of production to make the applicable payment to SN (for itself and on behalf of the other Buyer Parties) of proceeds attributable to production from the Assets from and after the Effective Time, for delivery by SN to the purchasers of production.

(f) From and after the Closing until the Transition Termination or, if either or both of the Marketing Agency Agreement and/or Midstream Agency Agreement are entered into by SN, Seller and, if applicable, AESC pursuant to Schedule 13.4, the date when such agreement(s) have terminated, each of SN, UnSub and AcqCo agrees that all of its production and Hydrocarbons attributable to the Assets will be transported and/or sold as provided in the Marketing Transition Services Agreement and, if applicable, the Marketing Agency Agreement and/or the Midstream Agency Agreement and it will not elect to takes its production in kind.

ARTICLE XII
ACCESS; DISCLAIMERS

12.1 Access.

(a) From and after the Execution Date and up to and including the Closing Date (or earlier termination of this Agreement), but subject to the other provisions of this Section 12.1 and obtaining any required consents of Third Parties, including Third Party operators of the Assets (which consents Seller shall use commercially reasonable efforts to obtain), Seller shall afford to Buyer and its officers, employees, agents, accountants, attorneys,

investment bankers and other authorized representatives (“Buyer’s Representatives”) reasonable access, during normal business hours, to (i) Seller’s and its Affiliates’ employees (following at least 72 hours prior notice to David Richardson at Seller), (ii) the Assets and (iii) all Records in Seller’s or any of its Affiliates’ possession. All investigations and due diligence conducted by Buyer or any Buyer’s Representative shall be conducted at Buyer’s sole cost, risk and expense and any conclusions made from any examination done by Buyer or any Buyer’s Representative shall result from Buyer’s own independent review and judgment.

(b) Buyer shall be entitled to conduct a Phase I environmental property assessments with respect to the Assets. Seller or its designee shall have the right to accompany Buyer and Buyer’s Representatives whenever they are on site on the Assets and also to collect split test samples if any are collected. Notwithstanding anything herein to the contrary, Buyer shall not have access to, and shall not be permitted to conduct, any environmental due diligence (including any Phase I environmental property assessments) with respect to any Assets where Seller does not have the authority to grant access for such due diligence (provided, however, Seller shall use its commercially reasonable efforts to obtain permission from any Third Party to allow Buyer and Buyer’s Representatives such access). Buyer shall not be entitled to conduct any sampling, boring, drilling or other invasive investigation activities on or with respect to any of the Assets without Seller’s prior written consent (which consent may be withheld by Seller in its sole discretion). To the extent that Seller gives it prior written consent (which it is under no obligation to give), any such sampling, boring, drilling or other invasive investigation activities to be conducted by Buyer shall be subject to the terms set forth in such prior written consent given by Seller.

(c) Buyer shall coordinate its environmental property assessments and physical inspections of the Assets with Seller and all Third Party operators to minimize any inconvenience to or interruption of the conduct of business by Seller or such Third Party operators. Buyer shall abide by Seller’s, and any Third Party operator’s, safety rules, regulations and operating policies while conducting its due diligence evaluation of the Assets, including any environmental or other inspection or assessment of the Assets. Buyer hereby defends, indemnifies and holds harmless each of the operators of the Assets and the Seller Indemnified Parties from and against any and all Liabilities arising out of, resulting from or relating to any field visit, environmental property assessment, or other due diligence activity conducted by Buyer or any Buyer’s Representative with respect to the Assets, EVEN IF SUCH LIABILITIES ARISE OUT OF OR RESULT FROM, SOLELY OR IN PART, THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OR VIOLATION OF LAW OF OR BY A MEMBER OF THE SELLER INDEMNIFIED PARTIES, EXCEPTING ONLY IN THE CASE OF THIS SECTION 12.1(C) LIABILITIES ACTUALLY RESULTING ON THE ACCOUNT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF A MEMBER OF THE SELLER INDEMNIFIED PARTIES.

(d) Buyer agrees to promptly provide Seller, but in no less than 5 days after Buyer’s or any of Buyer’s Representative’s receipt or creation, copies of all environmental reports and environmental test results prepared by Buyer or any of Buyer’s Representatives which contain environmental data collected or generated from Buyer’s environmental due diligence with respect to the Assets. None of Buyer, any of Buyer’s Representatives or Seller

shall be deemed by Seller’s receipt of said documents, or otherwise, to have made any representation or warranty, expressed, implied or statutory, as to the condition of the Assets or to the accuracy of said documents or the information contained therein.

(e) Upon completion of Buyer’s due diligence, Buyer shall at its sole cost and expense and without any cost or expense to Seller or its Affiliates, (i) repair all damage done to the Assets in connection with Buyer’s due diligence, (ii) restore the Assets to at least the approximate same or better condition than they were prior to commencement of Buyer’s due diligence and (iii) remove all equipment, tools or other property brought onto the Assets in connection with Buyer’s due diligence. Any disturbance to the Assets (including the leasehold associated therewith) resulting from Buyer’s due diligence will be promptly corrected by Buyer.

(f) During all periods that Buyer or any of Buyer’s Representatives are on the Assets, Buyer shall maintain, at its sole expense, policies of insurance of the types and in the amounts sufficient to cover the obligations and Liabilities of Buyer under Section 12.1(c) and Section 12.1(e). In connection with such insurance, Buyer shall cause its insurers to waive subrogation against the Seller Indemnified Parties. Upon request by Seller, Buyer shall provide to Seller evidence of such insurance and waiver of subrogation prior to entering the Assets.

12.2 Confidentiality. Buyer acknowledges that, pursuant to its right of access to the Records, the Assets, Buyer will become privy to confidential and other information of Seller and that such confidential information shall be held confidential by Buyer and Buyer’s Representatives in accordance with the terms of the Confidentiality Agreement as if each Buyer Party was a party thereto. If the Closing should occur, the foregoing confidentiality restriction on Buyer, including the Confidentiality Agreement, shall terminate (except as to (a) such portion of the Assets that are not conveyed to Buyer pursuant to the provisions of this Agreement, (b) the Excluded Assets and (c) information related to assets other than the Assets).

ARTICLE XIII
TITLE MATTERS; CASUALTY; TRANSFER RESTRICTIONS

13.1 Seller’s Title.

(a) General Disclaimer of Title Warranties and Representations. Without limiting Buyer’s remedies for Title Defects set forth in this Article XIII, Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to title to any of the Assets and, Buyer acknowledges and agrees that Buyer’s sole remedy for any defect of title, including any Title Defect, with respect to any of the Assets (i) before Closing, shall be as set forth in Section 13.2 and (ii) after Closing, shall be pursuant to the special warranty of Defensible Title to the Wells and Leases contained in the Assignments.

(b) Special Warranty of Defensible Title. The Assignments delivered at Closing will contain a special warranty of Defensible Title to the Wells and Leases by Seller whereby Seller warrants Defensible Title to the Wells and Leases unto Buyer against every Person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under Seller or any of its Affiliates, but not otherwise, subject, however, to the Permitted Encumbrances. For purposes of the special warranty of title to the Wells and Leases contained in the Assignment, the value of the Assets set forth in Exhibit A-1 and Exhibit A-2, as applicable, shall be deemed to be the Allocated Value thereof, as adjusted pursuant to this Agreement. Recovery on the special warranty of title to the Wells and Leases contained in the Assignment shall be limited to an amount (without any interest accruing thereon) equal to the reduction in the Purchase Price to which Buyer would have been entitled had Buyer asserted the Title Defect giving rise to such breach of the special warranty of title to the Wells and Leases contained in the Assignment, as applicable, as a Title Defect prior to Closing pursuant to Section 13.2, in each case without taking into account the Individual Title Defect Threshold and the Defect Deductible.

13.2 Notice of Title Defects; Defect Adjustments.

(a) Title Defect Notices. The Buyer Party Representative must deliver, on or before 5:00 p.m. (Prevailing Central Time) on February 22, 2017 (the “Title Claim Date”), claim notices to Seller meeting the requirements of this Section 13.2(a) (collectively the “Title Defect Notices” and individually a “Title Defect Notice”) setting forth any matters which, in

Buyer’s reasonable opinion, constitute Title Defects and which Buyer intends to assert as a Title Defect pursuant to this Section 13.2. For all purposes of this Agreement and notwithstanding anything herein to the contrary (except for the special warranty of Defensible Title to the Wells and Leases contained in the Assignments), Buyer shall be deemed to have waived, and Seller shall have no liability for, any Title Defect that Buyer fails to assert as a Title Defect by a Title Defect Notice received by Seller on or before the Title Claim Date. To be effective, each Title Defect Notice shall be in writing and shall include (i) a description of the alleged Title Defect and the Asset, or portion thereof, affected by such Title Defect (each a “Title Defect Property”), (ii) the Allocated Value of each Title Defect Property, (iii) supporting documents reasonably necessary for Seller to verify the existence of such Title Defect, and (iv) the amount by which Buyer reasonably believes the Allocated Value of each Title Defect Property is reduced by such Title Defect and the computations upon which Buyer’s belief is based. To give Seller an opportunity to commence reviewing and curing Title Defects, Buyer agrees to use reasonable efforts to give Seller, on or before the end of each calendar week prior to the Title Claim Date, written notice of all Title Defects discovered by Buyer during the preceding calendar week, which notice may be preliminary in nature and supplemented prior to the Title Claim Date. Buyer shall also promptly furnish Seller with written notice of any Title Benefit which is discovered by any of Buyer’s or any of its Affiliate’s employees, title attorneys, landmen or other title examiners while conducting Buyer’s due diligence with respect to the Assets prior to the Title Claim Date.

(b) Title Benefit Notices. Seller shall have the right, but not the obligation, to deliver to the Buyer Party Representative on or before the Title Claim Date with respect to each Title Benefit a notice (a “Title Benefit Notice”) including (i) a description of the Title Benefit and the Assets affected by the Title Benefit (each, a “Title Benefit Property”), (ii) supporting documents reasonably necessary for Buyer to verify the existence of such Title Benefit and (iii) the amount by which Seller reasonably believes the Allocated Value of such Assets is increased by the Title Benefit and the computations upon which Seller’s belief is based. Seller shall be deemed to have waived any Title Benefits that Seller fails to provide a Title Benefit Notice therefore on or before the Title Claim Date.

(c) Seller’s Right to Cure. Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure any Title Defects of which it has been advised by Buyer. The following shall apply with respect to each Title Defect that Seller attempts to cure pursuant to this Section 13.2(c):

(i) At any time prior to Closing, Seller may provide the Buyer Party Representative written notice that it will attempt to cure a Title Defect (each, a “Subject Title Defect”). If the Subject Title Defect is cured by Seller prior to Closing, the Asset subject to such Subject Title Defect shall be conveyed to Buyer at Closing, and there shall be no adjustment to the Purchase Price in respect of such Subject Title Defect. If the Subject Title Defect is not cured by Seller prior to Closing, (A) the Assets affected by such Subject Title Defect shall be conveyed to Buyer at Closing, (B) an amount equal to the Title Defect Amount of such Subject Title Defect (as determined by the mutual agreement of the Parties or if the Parties cannot agree, by Seller acting reasonably and in good faith) (such amount for each such Subject Title Defect, the “Defect Cure Escrow Amount”) shall be deducted from amounts otherwise payable at the Closing, and (C) at the Closing, Buyer shall deposit such Defect Cure Escrow Amount into an

escrow account established with the Escrow Agent pursuant to the terms of the Escrow Agreement pending the curing or resolution of the applicable Subject Title Defect.

(ii) Seller shall have a 90 day period after the Closing within which to attempt to cure each applicable Subject Title Defect not cured by Closing for which it has given the Buyer Party Representative notice of Seller’s intent to attempt to cure in accordance with Section 13.2(c)(i) above (the applicable cure period being hereinafter referred to in this Agreement as the “Cure Period”). Buyer agrees to reasonably cooperate with Seller in connection with Seller’s curative efforts, including in connection with any proceedings before a Governmental Authority; provided, however, Buyer shall not be obligated to pay any money to any Third Party (other than its or its Affiliates’ employees).

(iii) In the event that Seller believes that it has cured a Subject Title Defect after Closing within the Cure Period, Seller shall submit the applicable curative efforts in a notice to the Buyer Party Representative expressly identified as a “cure resolution notice”, together with all documentation and information reasonably necessary for Buyer to determine if such Subject Title Defect has been adequately cured. Buyer shall be deemed to have approved such curative efforts in the event the Buyer Party Representative does not notify Seller of an objection to the same (and the reasons therefor) within ten Days after the Buyer Party Representative’s receipt thereof. In the event Buyer so objects, the final resolution of such Subject Title Defect shall be determined by either (A) the mutual agreement of the Parties, or (B) the arbitration procedures under Section 13.2(j) below. Except with respect to curative efforts that Buyer has been deemed to have approved, each Party retains the right to dispute whether or not a Subject Title Defect has been cured and whether or not an alleged Title Defect constitutes a Title Defect and/or the Title Defect Amount with respect to such Title Defect, and any such dispute shall be resolved in accordance with the dispute resolution procedures set forth in Section 13.2(j), which dispute resolution procedures may be initiated by either Party on or after the date that is ten days after the end of the applicable Cure Period with respect to any Subject Title Defect.

(iv) Except for each Subject Title Defect that is submitted to arbitration pursuant to Section 13.2(c)(iii) and Section 13.2(j) (in which event the Defect Cure Escrow Amount deposited in escrow with respect thereto, if any, shall remain in escrow pending resolution of the applicable Subject Title Defect), with respect to each Subject Title Defect that has neither been cured prior to the expiration of the applicable Cure Period or waived by Buyer, Seller and Buyer shall jointly instruct the Escrow Agent to pay the Defect Cure Escrow Amount deposited into escrow on account thereof to Buyer. For all other Subject Title Defects subject to this Section 13.2(c), within ten days after the end of the Cure Period (or, if applicable, within ten days following the Title Arbitrator’s written decision under Section 13.2(j)), Seller and Buyer shall jointly instruct the Escrow Agent to pay the Defect Cure Escrow Amount deposited in escrow (or portion thereof) in respect of any Subject Title Defect (or portion thereof) that was cured to Seller, and pay the Defect Cure Escrow Amount deposited in escrow (or portion thereof) in respect of any Subject Title Defect (or portion thereof) that was not cured to Buyer;

(v) With respect to each Subject Title Defect that has been fully cured in accordance with the provisions hereof after the Closing but prior to the expiration of the Cure Period, Seller and Buyer shall (within 15 days following Seller’s notice of cure under Section

13.2(c)(iii)) jointly instruct the Escrow Agent to pay the Defect Cure Escrow Amount deposited into escrow on account thereof to Seller.

(d) Remedies for Title Defects. Subject to Seller’s right to cure following Closing pursuant to Section 13.2(c) and Seller’s continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto and subject to the rights of the Parties pursuant to Section 7.1(d), in the event that any Title Defect timely asserted by Buyer in accordance with Section 13.2(a) is not waived in writing by Buyer or cured on or before Closing, then, subject to the Individual Title Defect Threshold and the Defect Deductible, Seller shall, at its sole option, elect to:

(i) reduce the Purchase Price by the Title Defect Amount determined pursuant to Section 13.2(g) or Section 13.2(j);

(ii) indemnify Buyer against all Liability resulting from such Title Defect with respect to the Assets pursuant to an indemnity agreement in form and substance reasonably satisfactory to the Parties (each, a “Title Indemnity Agreement”); or

(iii) retain the entirety of the Title Defect Property that is subject to such Title Defect, together with all associated Assets, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Title Defect Property and such associated Assets, and such Title Defect Property and such associated Assets shall be deemed to be Excluded Assets;

provided, however, (1) Seller may elect the option set forth in clause (ii) above only to the extent Buyer consents in writing after the Execution Date to be bound by and subject to such option (such consent to be exercised, withheld, conditioned or delayed at the sole discretion of Buyer) and (2) prior to Closing, Buyer may rescind its Title Defect Notice in respect of such Title Defect by delivering notice thereof from the Buyer Party Representative to Seller, in which case Buyer shall be deemed to have waived such Title Defect for all purposes, including for purposes of the special warranty of Defensible Title contained in the Assignments.

(e) Remedies for Title Benefits. With respect to each Subject Well affected by Title Benefits reported under Section 13.2(b), as Seller’s sole and exclusive remedies for any Title Benefits, the amount (the “Title Benefit Amount”) equal to the increase in the Allocated Value for such Asset caused by such Title Benefits, as determined pursuant to Section 13.2(h), shall be applied as to offset the aggregate Title Defect Amounts attributable to Title Defects and the aggregate Remediation Amounts attributable to Environmental Defects.

(f) Exclusive Remedy. Except for Buyer’s (i) rights under the special warranty of Defensible Title to the Wells and Leases contained in the Assignments, and (ii) rights to terminate this Agreement pursuant to Section 7.1(d), the provisions set forth in Section 13.2(d) shall be the sole and exclusive right and remedy of Buyer with respect to Seller’s failure to have Defensible Title or any other title matter with respect to any Asset.

(g) Title Defect Amount. The amount by which the Allocated Value of the affected Title Defect Property is reduced as a result of the existence of a Title Defect shall be

the “Title Defect Amount” and shall be determined in accordance with the following terms and conditions:

(i) if Buyer and Seller agree on the Title Defect Amount, then that amount shall be the Title Defect Amount;

(ii) if the Title Defect is an Encumbrance that is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Defect Property;

(iii) if (A) the Title Defect represents a discrepancy between (1) Seller’s Net Revenue Interest for any Subject Well and (2) Seller’s Net Revenue Interest for such Subject Well as set forth in Exhibit A-1 or Exhibit A-2, as applicable, and (B) Seller’s Working Interest in such Subject Well is less than Seller’s Working Interest for such Subject Well as set forth in Exhibit A-1 or Exhibit A-2, as applicable, in the same proportion to such Net Revenue Interest decrease, then the Title Defect Amount shall be the product of (x) the Allocated Value of such Title Defect Property multiplied by (y) a fraction, the numerator of which is the Net Revenue Interest decrease in such Subject Well, and the denominator of which is the Net Revenue Interest for such Subject Well as set forth in Exhibit A-1 or Exhibit A-2, as applicable;

(iv) if the Title Defect represents an obligation, Encumbrance upon or other defect in title to the Title Defect Property of a type not described above, then the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property, the values placed upon the Title Defect by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation; provided, however, that if a Title Defect described in this Section��13.2(g)(iv) is reasonably capable of being cured, the Title Defect Amount shall not be greater than the reasonable cost and expense of curing such Title Defect;

(v) the Title Defect Amount with respect to a Title Defect Property shall be determined without duplication of any costs or losses included in another Title Defect Amount pertaining to such Title Defect Property hereunder;

(vi) if a Title Defect does not affect a Title Defect Property throughout the entire remaining productive life of such Title Defect Property, such fact shall be taken into account in determining the Title Defect Amount; and

(vii) notwithstanding anything to the contrary in this Article XIII, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any single Title Defect Property shall not exceed the Allocated Value of such Title Defect Property.

(h) Title Benefit Amount. The Title Benefit Amount resulting from a Title Benefit shall be determined in accordance with the following methodology, terms and conditions:

(i) if Buyer and Seller agree on the Title Benefit Amount, then that amount shall be the Title Benefit Amount;

(ii) if (A) the Title Benefit represents a discrepancy between (1) Seller’s Net Revenue Interest for any Subject Well, and (2) Seller’s Net Revenue Interest for such Subject Well as set forth in Exhibit A-1 or Exhibit A-2, as applicable, and (B) Seller’s Working Interest in such Subject Well is greater than Seller’s Working Interest for such Subject Well as set forth in Exhibit A-1 or Exhibit A-2, as applicable, in the same proportion to such Net Revenue Interest increase, then the Title Benefit Amount shall be the product of (x) the Allocated Value of the affected Subject Well multiplied by (y) a fraction, the numerator of which is the Net Revenue Interest increase in such Subject Well, and the denominator of which is the Net Revenue Interest for such Subject Well as set forth in Exhibit A-1 or Exhibit A-2, as applicable;

(iii) if the Title Benefit is of a type not described above, then the Title Benefit Amounts shall be determined by taking into account the Allocated Value of the Asset affected by such Title Benefit, the portion of such Asset affected by such Title Benefit, the legal effect of the Title Benefit, the potential economic effect of the Title Benefit over the life of such Asset, the values placed upon the Title Benefit by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation.

(i) Title Deductibles. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any individual Title Defect for which the Title Defect Amount does not exceed $250,000 (“Individual Title Defect Threshold”); and (ii) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any Title Defect that exceeds the Individual Title Defect Threshold unless (A) the sum of (1) the Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold (excluding any Title Defects cured by Seller), plus (2) all Remediation Amounts of all Environmental Defects that exceed the Individual Environmental Defect Threshold (excluding any Environmental Defects Remediated by Seller), minus (3) all Title Benefit Amounts, exceeds (B) the Defect Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price or other remedies only with respect to such Title Defects in excess of such Defect Deductible. For the avoidance of doubt, if Seller elects to exclude a Title Defect Property affected by a Title Defect from the transactions contemplated hereby pursuant to the remedy set forth in Section 13.2(d)(iii), then, after such election, the Title Defect Amount and related Purchase Price adjustment relating to such excluded Assets will not be counted towards the Defect Deductible or for purposes of Section 7.1(d).

(j) Title Dispute Resolution. Seller and Buyer shall attempt to agree on all Title Defects (that Seller has not elected to cure after Closing), Title Benefits, Title Defect Amounts (that do not relate to Title Defects that Seller has elected to cure after Closing) and Title Benefit Amounts prior to Closing. Seller and Buyer shall attempt to agree on all Title Defects that Seller has elected to cure and Title Defect Amounts relating thereto by the end of the Cure Period. Buyer and Seller shall attempt to agree on all claims asserted by Buyer under the special warranty of Defensible Title in the Assignments within 60 days following Seller’s receipt of a written special warranty claim by Buyer. If Seller and Buyer are unable to agree

by the time period specified above (as applicable) with respect to all such Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts in dispute, then such disputes and any dispute submitted by a Party pursuant to Section 13.2(c)(iii) shall be exclusively and finally resolved pursuant to this Section 13.2(j). There shall be a single arbitrator, who shall be a title attorney with at least 10 years’ experience in oil and gas titles involving properties in the regional area in which the Title Defect Properties are located, as selected by mutual agreement of Buyer and Seller within 15 days after the end of the Cure Period (the “Title Arbitrator”). In the event the Parties are unable to mutually agree upon the Title Arbitrator within such time period, then each Party will nominate a candidate to be the Title Arbitrator, and such candidates so nominated by the Parties shall together determine the Title Arbitrator. The arbitration proceeding shall be held in Houston, Texas. The Title Arbitrator’s determination shall be made within 20 days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Title Arbitrator shall be bound by the rules set forth in Section 13.2(g) and Section 13.2(h) and with respect to disputes regarding special warranty claims Section 13.1. The Title Arbitrator, however, may not award (1) Buyer a greater Title Defect Amount than the Title Defect Amount claimed by Buyer in its applicable Title Defect Notice or (2) Seller a greater Title Benefit Amount than the Title Benefit Amount claimed by Seller in its applicable Title Benefit Notice. Additionally, the Title Arbitrator may not award Buyer an amount for any special warranty claim greater than the amount claimed by Buyer in its applicable Title Defect Notice. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defect, Title Benefit, Title Defect Amounts and/or Title Benefit Amounts submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each of Seller and Buyer shall bear one-half of the costs and expenses of the Title Arbitrator and each of Seller and Buyer shall bear their own legal costs and other expenses incurred by such Party in connection with the arbitration unless the Title Arbitrator determines in writing with its award and decision a different allocation of costs and expenses between the Parties. Subject to the remaining provisions of this Section 13.2(j), to the extent that the award of the Title Arbitrator with respect to any Title Defect Amount or Title Benefit Amount is not taken into account as an adjustment to the Purchase Price pursuant to Section 3.5 or Section 3.6, then within ten days after the Title Arbitrator delivers written notice to Buyer and Seller of his award with respect to a Title Defect Amount or a Title Benefit Amount or special warranty claim and subject to Section 13.2(i) and Section 13.2(c)(ii), as applicable, (A) Buyer shall pay to Seller the amount, if any, so awarded by the Title Arbitrator to Seller and (B) Seller shall pay to Buyer the amount, if any, so awarded by the Title Arbitrator to Buyer. Subject to the remaining provisions of this Section 13.2(j), with respect to disputes submitted by a Party pursuant to Section 13.2(c), within ten days after the Title Arbitrator delivers written notice to Buyer and Seller of his award with respect to a Title Defect Amount and subject to Section 13.2(c)(iv) and Section 13.2(i), (x) Buyer and Seller shall jointly instruct the Escrow Agent to pay to Seller the amount, if any, so awarded by the Title Arbitrator to Seller and (y) Buyer and Seller shall jointly instruct the Escrow Agent to pay to Buyer the amount, if any, so awarded by the Title Arbitrator to Buyer. Nothing herein shall operate to cause the Closing to be delayed on account of any arbitration hereunder and to the extent any adjustments are not agreed upon by the Parties as of the Closing and Seller has not elected to cure any applicable Title Defect post-closing pursuant to Section 13.2(c), the Purchase Price

shall not be adjusted therefor as of the Closing and subsequent adjustments thereto, if any, will be made pursuant to Section 3.7 or this Section 13.2, as applicable.

13.3 Casualty or Condemnation Loss.

(a) Notwithstanding anything herein to the contrary from and after the Effective Time, if Closing occurs, Buyer 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 Personal Property 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 taken in condemnation or under right of eminent domain (each, a “Casualty Loss”), Buyer shall nevertheless be required to close and Seller, at the Closing, shall pay to Buyer all sums paid to Seller by Third Parties by reason of such Casualty Loss insofar as with respect to the affected Assets 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 Parties (excluding any Liabilities, other than insurance claims, of or against any Seller Indemnified Parties) arising out of such Casualty Loss insofar as with respect to the affected Assets; provided, however, that Seller shall reserve and retain (and Buyer shall assign to Seller) all rights, title, interests and claims against Third Parties 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 Third Parties with respect to any such Casualty Loss.

13.4 Consents to Assign.

(a) Other than with respect to the Marketing Contracts (which are addressed in Schedule 13.4) and except for consents to assignment that have been obtained in writing prior to the Execution Date, Seller, no later than 10 Business Days after the Execution Date, shall send to each holder of a right to consent to assignment pertaining to the Assets and the transactions contemplated hereby set forth in Schedule 9.4 (and with respect to any applicable consent to assignment not set forth in such schedule that is not related to a Marketing Contract, as soon as reasonably practicable following the discovery thereof, Seller shall send to the holder of such consent to assignment), a notice seeking such holder’s consent to the transactions contemplated hereby. Prior to Closing, Seller shall use its commercially reasonable efforts to obtain such consents to assignment (provided that Seller shall not be required to make payments or undertake obligations to or for the benefit of the holders of such rights in order to obtain any such consent). Prior to and after the Closing, Buyer shall use its reasonable efforts to evidence its financial ability (including by providing the materials set forth in Schedule 13.4(a)) to own the Assets as such evidence may be reasonably requested by (i) the lessors under the Leases, (ii) the co-owners of the Leases and (iii) the counterparties of the Applicable Contracts.

(b) Other than with respect to the Marketing Contracts (which are addressed in Schedule 13.4), if Seller fails to obtain a consent to the assignment of any Asset(s) prior to the Closing and (1) the failure to obtain such consent would cause the assignment of the Asset(s) affected thereby to Buyer to be void or the termination of a Lease or Right-of-Way

under the express terms thereof or (2) such consent in expressly denied in writing by the holder of such consent right (each, a “Hard Consent”), then

(i) other than with respect to the Marketing Contracts (which are addressed in Schedule 13.4), the Asset(s) subject to such Hard Consent and all Assets relating directly thereto, shall be excluded from the Assets to be acquired by Buyer at Closing hereunder, the Purchase Price shall not be adjusted on account thereof and, (A) if such affected Asset is a Lease or Well, then the Parties shall enter into a joint operating agreement covering such excluded Assets in substantially the form attached hereto as Exhibit O (the “JOA”) to govern future operations on such excluded Assets pending the receipt of such Hard Consent (provided that if a joint operating agreement with Third Parties relating to such Lease or Well is applicable, the JOA shall control as between the Parties) and (B) if such affected Asset is not a Lease or Well, then to the extent permitted under applicable Law and any applicable contracts, Seller shall hold the affected Asset for the benefit of Buyer after Closing and provide Buyer with all rights thereto and, effective as of Closing, Buyer hereby agrees to be responsible for, and defend, indemnify and hold harmless the Seller Indemnified Parties from, any and all obligations and Liabilities related to or arising out of such Affected Asset, including the operation thereof. In the event that such Hard Consent is obtained following Closing, then, Seller shall assign to Buyer, within 10 days after such Hard Consent is obtained, such Asset(s) so excluded under the terms of this Agreement pursuant to assignments in forms substantially similar to the Assignments; and

(ii) notwithstanding anything to the contrary in Section 13.4(b)(i), Buyer may elect by written notice to Seller following Closing to acquire any Asset (other than with respect to the Marketing Contracts which are addressed in Schedule 13.4) relating to any such Hard Consent which has not been obtained, and if Buyer so elects, then, within 10 days after delivery of such notice to Seller, Seller shall assign to Buyer such Asset(s) pursuant to an assignment in form substantially similar to the Assignment.

(c) If Seller fails to obtain a consent set forth in Schedule 9.4 (other than with respect to the Marketing Contracts which are addressed in Schedule 13.4) and such consent is not a Hard Consent or such consent is a Hard Consent and the provisions of Section 13.4(b)(ii) are applicable thereto, then (x) the Asset(s) subject to such un-obtained consent shall be acquired by Buyer at Closing (or pursuant to Section 13.4(b)(ii), as applicable) as part of the Assets, (y) Buyer shall have no claim against, and hereby releases and indemnifies the Seller Indemnified Parties from any Liability for, the failure to obtain such consent, and (z) Buyer shall be solely responsible from and after the Closing (or the date of Buyer’s acquisition of the affected Assets pursuant to Section 13.4(b)(ii), as applicable) for any and all Liabilities arising from the failure to obtain such consent, provided that, with respect to such consents that are not Hard Consents, for 90 days following the Closing Date, Seller shall cooperate with Buyer to obtain the consent of the holders of such consents but Seller shall not be required to spend any amount or incur any Liability in connection with such cooperation.

(d) As of the Execution Date, the Parties acknowledge that the consent attached hereto as Schedule 13.4(d) has been obtained.

ARTICLE XIV
ENVIRONMENTAL MATTERS

14.1 Notice of Environmental Defects.

(a) Environmental Defect Notices. If Buyer discovers any Environmental Condition which, in its reasonable opinion, Buyer determines constitutes an Environmental Defect, the Buyer Party Representative shall notify Seller on or before 5:00 p.m. (Prevailing Central Time) on February 22, 2017 (the “Environmental Claim Date”). To be effective, each notice of an Environmental Defect (an “Environmental Defect Notice”) shall be in writing and shall include (i) a reasonable description of the Environmental Condition constituting the asserted Environmental Defect(s), including the GPS coordinates of such Environmental Condition (when reasonably available), (ii) the Asset(s) (or portions thereof) affected by the asserted Environmental Defect (each, an “Environmental Defect Property”), (iii) documentation reasonably sufficient for Seller to verify the existence of the asserted Environmental Defect(s), (iv) the Allocated Value of each Environmental Defect Property (if applicable), (v) the Remediation Amount that Buyer asserts is attributable to such Environmental Defect and the computations and information upon which Buyer’s belief is based (including the proposed Remediation of such Environmental Defect) and (vi) the specific Environmental Law that is applicable to the Environmental Defect and the violation of such Environmental Law (to the extent applicable). To give Seller an opportunity to commence reviewing and curing Environmental Defects, Buyer agrees to use reasonable efforts to give Seller, on or before the end of each calendar week prior to the Environmental Claim Date, written notice of all Environmental Defects discovered by Buyer during the preceding calendar week, which notice may be preliminary in nature and supplemented prior to the Environmental Claim Date. For all purposes of this Agreement but subject to Buyer’s remedy for a breach of Seller’s representation contained in Section 9.14, Buyer shall be deemed to have waived, and Seller shall have no liability for, any Environmental Defect which Buyer fails to assert as an Environmental Defect by an Environmental Defect Notice received by Seller on or before the Environmental Claim Date.

(b) Seller’s Right to Cure. Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure at any time prior to the Closing any Environmental Defects of which it has been advised by Buyer.

(c) Remedies for Environmental Defects. Subject to Seller’s continuing right to dispute the existence of an Environmental Defect and/or the Remediation Amount asserted with respect thereto, and subject to the rights of the Parties pursuant to Section 7.1(e), in the event that any Environmental Defect timely asserted by Buyer in accordance with Section 14.1(a) is not waived in writing by the Buyer Party Representative or cured on or before Closing, then, subject to the Individual Environmental Defect Threshold and the Defect Deductible, Seller shall, at its sole option, elect to:

(i) reduce the Purchase Price by the Remediation Amount;

(ii) assume responsibility for the Remediation of such Environmental Defect;

(iii) retain the entirety of the Environmental Defect Property that is subject to such Environmental Defect, together with all associated Assets, in which event the Environmental Defect Property and such associated Assets shall be deemed to be Excluded Assets and the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Environmental Defect Property and/or such associated Assets; or

(iv) indemnify Buyer against all Liability resulting from such Environmental Defect with respect to the Environmental Defect Property pursuant to an indemnity agreement in form and substance reasonably satisfactory to the Parties (each, an “Environmental Indemnity Agreement”);

provided, however, in each instance Seller may elect the option set forth in clauses (ii), (iii) and (iv) above only to the extent the Buyer Party Representative consents in writing after the Execution Date to be bound by and subject to any such option (such consent to be exercised, withheld, conditioned or delayed at the sole discretion of the Buyer Party Representative). If Seller elects the option set forth in clause (i) above, Buyer shall be deemed to have assumed responsibility for all of the costs and expenses attributable to the Remediation of the Environmental Condition attributable to such Environmental Defect and such responsibility of Buyer shall be deemed to constitute part of the Assumed Obligations hereunder. If Seller elects, and Buyer consents to, the option set forth in clause (ii) above, Seller shall use reasonable efforts to implement such Remediation in a manner which is consistent with the requirements of Environmental Laws in a timely fashion for the type of Remediation that Seller elects to undertake; provided that (A) if Seller is unable to complete such Remediation prior to Closing, Seller shall retain the entirety of the Environmental Defect Property that is subject to the Environmental Defect, together with all associated Assets, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Environmental Defect Property and/or such associated Assets, (B) if Seller completes such Remediation to the satisfaction of the applicable Governmental Authority having jurisdiction over such Remediation (or if a Governmental Authority has not been notified by Seller of the existence of the applicable Environmental Defect, then to Buyer’s reasonable satisfaction) before the end of the Cure Period, Seller shall promptly convey the Environmental Defect Property and all associated Assets to Buyer under forms of assignment substantially similar to the Assignments, and Buyer shall promptly pay the Allocated Value of such Assets to Seller, and (C) if Seller does not complete such Remediation to the satisfaction of the applicable Governmental Authority having jurisdiction over such Remediation (or if a Governmental Authority has not been notified by Seller of the existence of the applicable Environmental Defect, then to Buyer’s reasonable satisfaction) before the end of the Cure Period, such Assets shall be deemed to be Excluded Assets.

(d) Exclusive Remedy. Except as provided in Section 8.2(a) for a breach of Seller’s representations and warranties set forth in Section 9.14 and Buyer’s rights to terminate this Agreement pursuant to Section 7.1(d), the provisions set forth in Section 14.1(c) shall be the exclusive right and remedy of Buyer with respect to any Environmental Defect with respect to any Asset.

(e) Environmental Deductibles. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided

by Seller for any individual Environmental Defect (or with respect to any specific Asset, Environmental Defects in the aggregate) for which the Remediation Amount does not exceed $250,000 (“Individual Environmental Defect Threshold”); and (ii) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any Environmental Defect (or with respect to any specific Asset, Environmental Defects in the aggregate) for which the Remediation Amount exceeds the Individual Environmental Defect Threshold unless (A) the sum of (1) the Remediation Amounts of all such Environmental Defects that exceed the Individual Environmental Defect Threshold (excluding any Environmental Defects cured by Seller), plus (2) the Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold (excluding any Title Defects cured by Seller), minus (3) all Title Benefit Amounts, exceeds (B) the Defect Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price or other remedies only with respect to such Environmental Defects in excess of the Defect Deductible. For the avoidance of doubt, if Seller elects to exclude an Environmental Defect Property affected by an Environmental Defect from the transactions contemplated hereby pursuant to the remedy set forth in Section 14.1(c)(ii), then, after such election, the Remediation Amount and related Purchase Price adjustment relating to such excluded Assets will not be counted towards the Defect Deductible or for purposes of Section 7.1(d).

(f) Environmental Dispute Resolution. Seller and Buyer shall attempt to agree on all Environmental Defects and Remediation Amounts prior to Closing. If Seller and Buyer are unable to agree by Closing, the Environmental Defects and/or Remediation Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 14.1(f). There shall be a single arbitrator, who shall be an environmental attorney with at least 10 years’ experience in environmental matters involving oil and gas producing properties in the regional area in which the affected Assets are located, as selected by mutual agreement of Buyer and Seller within 15 days after the Closing Date (the “Environmental Arbitrator”). In the event the Parties are unable to mutually agree upon the Environmental Arbitrator within such time period, then each Party will nominate a candidate to be the Environmental Arbitrator, and such candidates so nominated by the Parties shall together determine the Environmental Arbitrator. The arbitration proceeding shall be held in Houston, Texas. The Environmental Arbitrator’s determination shall be made within 20 days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Environmental Arbitrator shall be bound by the rules set forth in this Section 14.1. The Environmental Arbitrator, however, may not award Buyer its share of any greater Remediation Amount than the Remediation Amount claimed by Buyer in its applicable Environmental Defect Notice. The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defects and/or Remediation Amounts submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each of Seller and Buyer shall bear one-half of the costs and expenses of the Environmental Arbitrator. To the extent that the award of the Environmental Arbitrator with respect to any Remediation Amount is not taken into account as an adjustment to the Purchase Price pursuant to Section 3.5 or Section 3.6, then within 10 days after the Environmental Arbitrator delivers written notice to Buyer and Seller of his award with respect to a Remediation Amount, and subject to Section 14.1(e), (i) Buyer shall pay to Seller the amount, if any, so awarded by the Environmental Arbitrator to Seller and (ii) Seller shall

pay to Buyer the amount, if any, so awarded by the Environmental Arbitrator to Buyer. Nothing herein shall operate to cause the Closing to be delayed on account of any arbitration hereunder and to the extent any adjustments are not agreed upon by the Parties as of the Closing, the Purchase Price shall not be adjusted therefor as of the Closing and subsequent adjustments thereto, if any, will be made pursuant to Section 3.7 or this Section 14.1.

14.2 NORM, Wastes and Other Substances. Buyer acknowledges that the Assets have been used for exploration, development, production, gathering and transportation of oil and Gas and there may be petroleum, produced water, wastes or other substances or materials located in, on or under the Assets or associated with the Assets. Equipment and sites included in the Assets may contain asbestos, NORM or other Hazardous Substances. NORM may affix or attach itself to the inside of wells, pipelines, materials and equipment as scale, or in other forms. The wells, materials and equipment located on the Assets or included in the Assets may contain NORM and other wastes or Hazardous Substances. NORM containing material or other wastes or Hazardous Substances may have come in contact with various environmental media, including, water, soils or sediment. Special procedures may be required for the assessment, remediation, removal, transportation or disposal of environmental media, wastes, asbestos, NORM and other Hazardous Substances from the Assets. For the avoidance of doubt (a) NORM shall not constitute the basis of a breach of Seller’s representations and warranties set forth in Section 9.14, and (b) no Environmental Condition involving NORM shall constitute the basis of an Environmental Defect unless such NORM is in violation of Environmental Law.

ARTICLE XV
MISCELLANEOUS

15.1 Exhibits and Schedules. All of the Exhibits and Schedules referred to in this Agreement constitute a part of this Agreement. Seller or Buyer and their respective counsel have received a complete set of Exhibits and Schedules prior to and as of the execution of this Agreement.

15.2 Expenses and Taxes.

(a) Except as otherwise specifically provided, all fees, costs and expenses incurred by Seller or Buyer in negotiating this Agreement or in consummating the transactions contemplated by this Agreement shall be paid by the Person incurring the same, including, legal and accounting fees, costs and expenses.

(b) All required documentary, filing and recording fees and expenses in connection with the filing and recording of the assignments (including the Assignments), conveyances or other instruments required to convey title to the Assets to Buyer shall be borne by Buyer. Buyer shall assume responsibility for, and shall bear and pay, all state sales and use Taxes and transfer and similar Taxes (including any applicable interest or penalties) incurred or imposed with respect to the transactions described in this Agreement (the “Transfer Taxes”). Seller shall assume responsibility for, and shall bear and pay, all Asset Taxes assessed with respect to the ownership and operation of the Assets for (i) any period ending prior to the Effective Time, and (ii) the portion of any Straddle Period ending immediately prior to the Effective Time. All Asset Taxes with respect to the ownership or operation of the Assets arising on or after the Effective Time (including all Straddle Period Asset Taxes not apportioned to Seller) shall be allocated to and borne by Buyer. Upon determination of the

actual amount of Asset Taxes, to the extent not taken into account under Section 3.3, payments will be made to cause the appropriate Party to bear the Asset Taxes allocable to such Person under this Section 15.2(b). For purposes of allocation between the Parties of Asset Taxes that are payable with respect to Straddle Periods, the portion of any such Taxes that are attributable to the portion of the Straddle Period that ends immediately prior to the Effective Time shall (A) in the case of Taxes that are based upon or related to income or receipts or imposed on a transactional basis, be deemed equal to the amount that would be payable if the Tax year or period ended immediately prior to the Effective Time; and (B) in the case of other Taxes, be allocated pro rata per day between the period immediately prior to the Effective Time and the period beginning on the Effective Time. For purposes of clause (A) of the preceding sentence, any exemption, deduction, credit or other item that is calculated on an annual basis shall be allocated pro rata per day between the period ending immediately prior to the Effective Time and the period beginning on the Effective Time.

(c) To the extent the actual amount of an Asset Tax is not known at the time an adjustment is to be made with respect to such Asset Tax pursuant to Section 3.3, Section 3.4 or Section 3.5, as applicable, the Parties shall utilize the most recent information available in estimating the amount of such Asset Tax for purposes of such adjustment. To the extent the actual amount of an Asset Tax (or the amount thereof paid or economically borne by a Party) is ultimately determined to be different than the amount (if any) that was taken into account in the Final Settlement Statement as finally determined pursuant to Section 3.6, timely payments will be made from one Party to the other to the extent necessary to cause each Party to bear the amount of such Asset Tax that is allocable to such Party under Section 15.2(b).

(d) Seller shall timely file any Tax Return with respect to Asset Taxes due on or before the Closing Date or that otherwise relates solely to periods before the Closing Date (a “Pre-Closing Tax Return”) and shall pay any Asset Taxes shown due and owing on such Pre-Closing Asset Tax Return, subject to Seller’s right of reimbursement for any Asset Taxes for which Buyer is responsible under Section 15.2(b). From and after the Closing Date, Buyer shall timely file any Tax Returns with respect to Asset Taxes required to be filed after the Closing Date, including such Tax Returns for any Straddle Period that are due after the Closing Date (a “Post-Closing Tax Return”), and shall pay any Asset Taxes shown due and owing on such Post-Closing Tax Return, subject to Buyer’s right of reimbursement for any Asset Taxes for which Seller is responsible under Section 15.2(b). Buyer shall file any Post-Closing Tax Return relating to a Straddle Period in a manner consistent with past practice. Within 15 days prior to filing, Buyer shall deliver to Seller a draft of any such Post-Closing Tax Return for Seller’s review and approval (which approval will not be unreasonably withheld or delayed).

(e) Any payments made to any Party pursuant to Article VIII shall constitute an adjustment of the Purchase Price for Tax purposes and shall be treated as such by Buyer and Seller on their Tax Returns to the extent permitted by applicable Law.

(f) The Parties shall cooperate fully, as and to the extent reasonably in connection with the filing of any Tax Returns, State and Federal regulatory reports, royalty payments including related deduction and any audit, litigation or other proceeding with respect to these matters for the Assets. Such cooperation shall include the retention of records and

information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Buyer agrees to allow access (upon request) to the Assets by Seller, Seller representatives, auditors and State or Federal representatives relevant to any such audit, litigation or other proceeding.

15.3 Assignment. This Agreement may not be assigned by Buyer or Seller without the prior written consent of each Party. In the event the Parties consent to any such assignment, such assignment shall not relieve (a) the assigning Party of any obligations and responsibilities hereunder or (b) SN Parent of its obligations and responsibilities pursuant to Section 15.22. Any assignment or other transfer by Buyer or its successors and assigns of any of the Assets shall not relieve Buyer or its successors or assigns of any of their obligations (including indemnity obligations) hereunder, as to the Assets so assigned or transferred.

15.4 Preparation of Agreement. Seller, Buyer and their respective counsel participated in the preparation of this Agreement. In the event of any ambiguity in this Agreement, no presumption shall arise based on the identity of the draftsman of this Agreement.

15.5 Publicity.

(a) Neither Party shall make or issue any press release or other announcements to the general public concerning the transactions contemplated by this Agreement without the prior consent of the other Party, which consent shall not be unreasonably withheld. If either Party desires to make an announcement to the general public, it shall first give the other Party 48 hours written notification of its desire to make such a public announcement. The written notification shall include (i) a request for consent to make the announcement, and (ii) a written draft of the text of such public announcement.

(b) Nothing in this Section 15.5 shall prohibit any Party from issuing or making a public announcement or statement if such Party deems it necessary to do so in order to comply with any applicable Law or the rules of any stock exchange upon which the Party’s or a Party’s Affiliate’s capital stock is traded; provided, however, that to the extent possible, prior written notification shall be given to the other Parties prior to any such announcement or statement.

15.6 Notices. All notices and communications required or permitted to be given hereunder shall be in writing and shall be delivered personally, or sent by bonded overnight courier, or mailed by U.S. Express Mail or by certified or registered United States Mail with all postage fully prepaid, or sent by electronic mail transmission (provided that the acknowledgment of the receipt of such electronic mail is requested and received by email, excluding automatic receipts, and such notice and communications are sent promptly thereafter to the reviewing person via overnight courier, U.S. Express Mail or certified or registered United States Mail) addressed to Seller or Buyer, as appropriate, at the address for such Person shown below or at such other address as Seller or Buyer shall have theretofore designated by written notice delivered to the other Parties:

15.8 Filings, Notices and Certain Governmental Approvals. Promptly after the Closing, Buyer shall (a) record all assignments of state Leases executed at the Closing in the records of the applicable Governmental Authority, (b) if applicable, send notices to vendors supplying goods and services for the Assets and to the operator of such Assets of the assignment of such Assets to Buyer, (c) actively pursue the unconditional approval of all applicable Governmental Authorities of the assignment of the Assets to Buyer and (d) actively pursue all other consents and approvals that may be required in connection with the assignment of the Assets to Buyer and the assumption of the Liabilities assumed by Buyer hereunder, that, in each case, shall not have been obtained prior to the Closing; provided that Seller shall cooperate with Buyer in satisfying clauses (a) through (d) of this Section 15.8 as may be reasonably necessary; provided further that Seller shall not be required to incur any Liability or pay any money in connection with such cooperation. Buyer obligates itself to take any and all action required by any Governmental Authority in order to obtain such unconditional approval, including the posting of any and all bonds or other security that may be required in excess of its existing lease, pipeline or area-wide bond.

15.9 Entire Agreement; Conflicts; No Third-Party Beneficiaries.

(a) THIS AGREEMENT, THE EXHIBITS AND SCHEDULES HERETO, THE TRANSACTION DOCUMENTS AND THE CONFIDENTIALITY AGREEMENT COLLECTIVELY CONSTITUTE THE ENTIRE AGREEMENT AMONG SELLER AND BUYER PERTAINING TO THE SUBJECT MATTER HEREOF AND SUPERSEDE ALL PRIOR AGREEMENTS, UNDERSTANDINGS, NEGOTIATIONS AND DISCUSSIONS,

WHETHER ORAL OR WRITTEN, OF SELLER AND BUYER PERTAINING TO THE SUBJECT MATTER HEREOF.

(b) The Parties expressly acknowledge and agree that, in the event that the Closing occurs, the Confidentiality Agreement shall be terminated in its entirety effective as of the Closing Date.

(c) THERE ARE NO WARRANTIES, REPRESENTATIONS OR OTHER AGREEMENTS AMONG SELLER AND BUYER RELATING TO THE SUBJECT MATTER HEREOF EXCEPT AS SPECIFICALLY SET FORTH IN THIS AGREEMENT, AND NEITHER SELLER NOR BUYER SHALL BE BOUND BY OR LIABLE FOR ANY ALLEGED REPRESENTATION, PROMISE, INDUCEMENT OR STATEMENTS OF INTENTION NOT SO SET FORTH. IN THE EVENT OF A CONFLICT BETWEEN THE TERMS AND PROVISIONS OF THIS AGREEMENT AND THE TERMS AND PROVISIONS OF ANY EXHIBIT HERETO, THE TERMS AND PROVISIONS OF THIS AGREEMENT SHALL GOVERN AND CONTROL; PROVIDED, HOWEVER, THAT THE INCLUSION IN ANY OF THE EXHIBITS HERETO OF TERMS AND PROVISIONS NOT ADDRESSED IN THIS AGREEMENT SHALL NOT BE DEEMED A CONFLICT, AND ALL SUCH ADDITIONAL PROVISIONS SHALL BE GIVEN FULL FORCE AND EFFECT, SUBJECT TO THE PROVISIONS OF THIS SECTION 15.9.

(d) The terms and provisions of this Agreement are intended solely for the benefit of the Parties, their respective successors or permitted assigns, and it is not the intention of the Parties to confer third-party beneficiary rights upon any other Person; provided, however, that notwithstanding the foregoing, the Financing Sources, their Affiliates and their respective Representatives shall be express third party beneficiaries of, and shall be entitled to enforce (and entitled to rely on), Section 7.2(f), this Section 15.9(d), Section 15.11, Section 15.13, Section 15.18 and Section 15.20.

15.10 Parties in Interest. The terms and provisions of this Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns. Notwithstanding anything contained in this Agreement to the contrary, nothing in this Agreement, expressed or implied, is intended to confer on any Person other than Seller and Buyer and their respective successors and permitted assigns, or the Parties’ respective related Indemnified Parties hereunder, any rights, remedies, obligations or liabilities under or by reason of this Agreement; provided that only a Party and its respective successors and permitted assigns will have the right to enforce the provisions of this Agreement on its own behalf or on behalf of any of its related Indemnified Parties (but shall not be obligated to do so).

15.11 Amendment. This Agreement may be amended only by an instrument in writing executed by the Party against whom enforcement is sought. Notwithstanding anything to the contrary in this Section 15.11 or in Article VII, (i) this Agreement may not be amended, supplemented or modified with respect to Section 7.2(f), Section 15.9(d), this Section 15.11, Section 15.13, Section 15.20, or the definitions of “Debt Financing Sources” or “Equity Financing Sources”, and (ii) no term or condition of this Agreement with respect to Section 15.9(d), this Section 15.11, Section 15.13, Section 15.18, Section 15.20, or the definitions of “Debt Financing Sources” or “Equity Financing Sources” may be waived by any Party to the extent such amendment, supplement, modification or waiver would modify the substance of such

sections, in the cases of clauses (i) and (ii), in a manner that is adverse to the interests of the Financing Sources without the written consent of the Financing Sources.

15.12 Waiver; Rights Cumulative. Any of the terms, covenants, representations, warranties or conditions hereof may be waived only by a written instrument executed by or on behalf of the Party waiving compliance. No course of dealing on the part of Seller or Buyer, or their respective officers, employees, agents or representatives or any failure by Seller or Buyer to exercise any of its rights under this Agreement shall operate as a waiver thereof or affect in any way the right of such Person at a later time to enforce the performance of such provision. No waiver by Seller or Buyer of any condition or any breach of any term, covenant, representation or warranty contained in this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such condition or breach or a waiver of any other condition or of any breach of any other term, covenant, representation or warranty. The rights of Seller and Buyer under this Agreement shall be cumulative, and the exercise or partial exercise of any such right shall not preclude the exercise of any other right.

15.13 Conflict of Law Jurisdiction, Venue; Jury Waiver. THIS AGREEMENT (INCLUDING ANY FINANCING CLAIM) AND THE LEGAL RELATIONS AMONG SELLER AND BUYER SHALL BE GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, EXCLUDING ANY CONFLICTS OF LAW RULE OR PRINCIPLE THAT WOULD REQUIRE THE APPLICATION OF ANY OTHER LAW. EACH OF SELLER AND BUYER CONSENT TO THE EXERCISE OF JURISDICTION IN PERSONAM BY THE COURTS OF THE STATE OF TEXAS FOR ANY ACTION ARISING OUT OF THIS AGREEMENT, THE OTHER TRANSACTION DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY (INCLUDING ANY FINANCING CLAIM). ALL ACTIONS OR PROCEEDINGS WITH RESPECT TO, ARISING DIRECTLY OR INDIRECTLY IN CONNECTION WITH, OUT OF, RELATED TO OR FROM THIS AGREEMENT OR THE OTHER TRANSACTION DOCUMENTS (INCLUDING ANY FINANCING CLAIM) SHALL BE EXCLUSIVELY LITIGATED IN COURTS HAVING SITES IN HOUSTON, HARRIS COUNTY, TEXAS. EACH OF SELLER AND BUYER WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT (INCLUDING ANY FINANCING CLAIM). NOTWITHSTANDING THE FOREGOING, SELLER AGREES THAT IT WILL NOT BRING, AND WILL NOT PERMIT OR SUPPORT ANY OF ITS AFFILIATES TO BRING, ANY FINANCING CLAIM IN ANY FORUM OTHER THAN THE SUPREME COURT OF THE STATE OF NEW YORK, COUNTY OF NEW YORK, OR IF UNDER APPLICABLE LAW EXCLUSIVE JURISDICTION IS VESTED IN FEDERAL COURTS, THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK (AND THE APPELLATE COURTS THEREOF) AND FURTHER AGREES THAT (X) THE WAIVER OF JURY TRIAL SET FORTH IN THIS SECTION 15.13 SHALL BE APPLICABLE TO ANY SUCH PROCEEDING AND (Y) ANY SUCH PROCEEDING DESCRIBED IN THE PRECEDING SENTENCE SO BROUGHT IN SUCH FORUM AGAINST ANY OF THE FINANCING SOURCES SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES.

15.14 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any adverse manner to any of Seller or Buyer. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

15.15 Removal of Name. As promptly as practicable, but in any case within 30 days after the Closing Date, Buyer shall eliminate the names Anadarko and Kerr-McGee and any variants thereof from the Assets acquired pursuant to this Agreement and, except with respect to such grace period for eliminating existing usage, shall have no right to use any logos, trademarks or trade names belonging to Seller or any of its Affiliates.

15.16 Like-Kind Exchange. Notwithstanding anything else in this Agreement, each Party shall have the right to structure the transactions contemplated under the terms of this Agreement as a Like-Kind Exchange. Notwithstanding any other provisions of this Agreement, in connection with effectuating a Like-Kind Exchange, each Party shall have the right, at or prior to the Closing Date or any subsequent closing, to assign all or a portion of its rights under this Agreement (the “Assigned Rights”) to a “qualified intermediary” (as that term is defined in Section 1.1031(k)-1(g)(4) of the Treasury Regulations) or to a “qualified exchange accommodation titleholder” (as that term is defined in U.S. Revenue Procedure 2000-37) (in either case, a “Qualifying Party”). In the event a Party (in its capacity as an exchanging party, referred to in this Section 15.16 as an “Exchanging Party”) assigns the Assigned Rights to a Qualifying Party pursuant to this Section 15.16, then such Exchanging Party agrees to notify the other Party in writing of such assignment reasonably in advance of the Closing Date. In addition, should a Party choose to effectuate a Like-Kind Exchange, the Parties agree to use reasonable best efforts to cooperate with one another in the completion of such an exchange, including the execution of all documents reasonably necessary to effectuate such a Like-Kind Exchange; provided, however, that (a) the Closing Date shall not be delayed or affected by reason of the Like-Kind Exchange, (b) the Exchanging Party shall effect its Like-Kind Exchange through an assignment of the Assigned Rights to a Qualifying Party but such assignment shall not release such Exchanging Party from any of its liabilities or obligations under this Agreement and (c) the non-Exchanging Party shall incur no additional unreimbursed costs, expenses, fees or liabilities as a result of or in connection with the exchange requested by the Exchanging Party. Each of Seller and Buyer hereby acknowledge and agree that any assignment of this Agreement pursuant to this Section 15.16 shall not release a Party from, or modify, any of its respective liabilities and obligations (including indemnity obligations to each other) under this Agreement. Neither Seller nor Buyer, by its consent to a Like-Kind Exchange, shall be responsible in any way for the Exchanging Party’s compliance with such Like-Kind Exchange.

15.17 Counterparts. This Agreement may be executed in any number of counterparts, and each such counterpart hereof shall be deemed to be an original instrument, but all of such counterparts shall constitute for all purposes one agreement. Any signature hereto delivered by a Party by facsimile transmission shall be deemed an original signature hereto.

15.18 No Recourse. Notwithstanding anything that may be expressed or implied in this Agreement or any document, agreement, or instrument delivered contemporaneously herewith, and notwithstanding the fact that any Party may be a partnership or limited liability company, and (x) other than to the extent expressly provided in the Equity Commitment Letters, the SN Parent Guaranty or the Blackstone Guaranty (collectively, the “Buyer Security Documents”) and except with respect to any issuer of any letter-of credit provided by an Buyer Party pursuant to this Agreement, including the Deposit LOC (“Buyer LOCs”), and then (in each case) only to the extent of the specific obligations undertaken thereunder by such named party therein, and (y) other than under the Escrow Agreement or with respect to any Contract that Seller or its Affiliates have with any Debt Financing Sources related to the marketing of the Assets (collectively, each, a “Seller Asset Marketing Agreements”), each Party hereto and SN Parent, by its acceptance of the benefits of this Agreement, covenants, agrees and acknowledges that no Persons other than the Parties and SN Parent shall have any obligation hereunder and that it has no rights of recovery hereunder against, and no recourse hereunder or under any documents, agreements, or instruments delivered contemporaneously herewith or in respect of any oral representations made or alleged to be made in connection herewith or therewith shall be had (a) against any former, current, or future general or limited partner, manager, stockholder or member of any Party (or any of their successors or permitted assignees) or any Affiliate thereof or any Debt Financing Source or (b) against any former, current or future director, officer, agent, attorney, financing source (including the Debt Financing Sources), employee, Affiliate, manager, assignee, incorporator, controlling Person, fiduciary, representative, general or limited partner, stockholder, manager or member of any of the foregoing, but in each case not including the Parties or SN Parent (each of the parties in clauses (a) and (b), but excluding for the avoidance of doubt, the Parties and SN Parent, a “Party Affiliate”), whether by or through attempted piercing of the corporate veil, by or through a claim (whether in tort, contract or otherwise) by or on behalf of such Party against the Party Affiliates, by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable Law, or otherwise; it being expressly agreed and acknowledged that (other than to the extent expressly provided in any Buyer Security Documents or Buyer LOC and then only to the extent of the specific obligations undertaken by such named party therein, and other than with respect to any Seller Asset Marketing Agreement) no personal liability whatsoever shall attach to, be imposed on, or otherwise be incurred by any Party Affiliate, as such, for any obligations of the applicable Party under this Agreement or the transactions contemplated hereby, under any documents or instruments delivered contemporaneously herewith, in respect of any oral representations made or alleged to be made in connection herewith or therewith, or for any claim (whether in tort, contract or otherwise) based on, in respect of, or by reason of, such obligations or their creation. Each Party Affiliate is expressly intended as a third-party beneficiary of this Section 15.18.

15.19 Remedies. The Parties hereto agree that irreparable damage would occur in the event that any provision of this Agreement contemplated to be performed prior to, or contemporaneous with, Closing was not performed by Buyer or Seller in accordance with the terms hereof and that monetary damages, even if available, would not be an adequate remedy therefor. Subject to Section 7.2(e), as a result, prior to the termination of this Agreement, each party shall be entitled to specific performance to prevent breaches of this Agreement and of the terms hereof (including the obligation to consummate transactions contemplated hereby, subject to the terms and conditions hereof), without proof of actual damages (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy)

in addition to any other remedy at Law or equity. In connection with the exercise of any Party’s rights under this Section 15.19, the Parties agree not to assert that a remedy of specific performance is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for any such breach.

15.20 Waiver of Claims Against Debt Financing Sources. Notwithstanding anything in this Agreement to the contrary, Seller agrees, on behalf of itself and its Affiliates, that (a) none of the Debt Financing Sources (solely in their respective capacities as Debt Financing Sources) or any former, current or future director, officer, agent, attorney, employee, Affiliate, manager, assignee, incorporator, controlling Person, fiduciary, representative, general or limited partner, stockholder, manager or member of any Debt Financing Source shall have any Liability to Seller or its Affiliates relating to or arising out of this Agreement or the transactions contemplated by this Agreement, including the financing of the transactions contemplated by this Agreement, whether at law or equity, in contract, in tort or otherwise, and (b) neither Seller nor any of its Affiliates (i) will have any rights or claims against any Debt Financing Source (solely in their respective capacities as Debt Financing Sources) or any former, current or future director, officer, agent, attorney, employee, Affiliate, manager, assignee, incorporator, controlling Person, fiduciary, representative, general or limited partner, stockholder, manager or member of any Debt Financing Source under this Agreement or any other agreement contemplated by, or entered into in connection with, the transactions contemplated by this Agreement, including any commitments by the Debt Financing Sources in respect of financing the transactions contemplated by this Agreement, (ii) seek to enforce this Agreement against any Debt Financing Source (solely in their respective capacities as Debt Financing Sources) or any former, current or future director, officer, agent, attorney, employee, Affiliate, manager, assignee, incorporator, controlling Person, fiduciary, representative, general or limited partner, stockholder, manager or member of any Debt Financing Source or (iii) bring any claim or cause of action against any Debt Financing Source (solely in their respective capacities as Debt Financing Sources) or any former, current or future director, officer, agent, attorney, employee, Affiliate, manager, assignee, incorporator, controlling Person, fiduciary, representative, general or limited partner, stockholder, manager or member of any Debt Financing Source under this Agreement or any other agreement contemplated by, or entered into in connection with, the transactions contemplated by this Agreement, including any commitments by the Debt Financing Sources in respect of financing the transactions contemplated by this Agreement. For the avoidance of doubt, however, this Section 15.20 shall not apply to any rights Seller may have under any Buyer Security Document, any Buyer LOC or any Seller Asset Marketing Agreement.

15.21 Buyer Party Representative. Each Buyer Party hereby irrevocably appoints SN as the sole representative of the Buyer Parties (in such capacity, “Buyer Party Representative”) to act as the agent and on behalf of each such Buyer Party for the purposes of: (a) any matters related to the Hedging Transactions, including the entry, assignment, or novation thereof; and (b) any title and/or environmental matters set forth in Articles XIII and XIV. As the representative of the Buyer Parties, the Buyer Party Representative shall act as the agent for each Buyer Party and shall have authority to bind each such Buyer Party. Seller may conclusively and absolutely rely, without inquiry, upon the action of the Buyer Party Representative as the action of each Seller in all matters referred to in this Section 15.21.

15.22 SN Parent Guaranty. For good and valuable consideration, and to induce Seller to enter into this Agreement, SN Parent hereby absolutely, unconditionally and irrevocably guarantees to Seller the punctual and complete performance of all obligations of SN under this Agreement other than payment of the SN Parties’ Proportionate Shares of the Purchase Price (the “Obligations”). The guaranty set out in this Section 15.22 (the “SN Parent Guaranty”) shall remain in full force and effect until SN has fully discharged all of the Obligations. Upon default by SN of any of the Obligations, Seller may proceed directly against SN Parent without proceeding against SN or any other Person or pursuing any other remedy. Seller may, without notice to, or consent of, SN Parent, (i) extend or alter, together with SN, the time, manner, place or terms of payment or performance of the Obligations, (ii) waive, or, together with SN, amend the terms of this Agreement, (iii) release SN from any or all of the Obligations, or (iv) release any other guaranty or security for the Obligations, without in any way releasing or discharging SN Parent from liability hereunder. SN Parent waives any defenses (but not rights of set-off or counterclaims) which it may have with respect to the performance of the Obligations, other than defenses that SN would have under the terms of this Agreement. SN Parent further waives notice of the acceptance of this SN Parent Guaranty, presentment, demand, protest, and notices of protest, nonpayment, default or dishonor of the Obligations. SN Parent represents and warrants that (A) it has the full power and authority to enter into and perform the SN Parent Guaranty, (B) there are no bankruptcy, reorganization or receivership proceedings pending, being contemplated by or, to SN Parent’s knowledge, threatened against SN Parent, and SN Parent is not insolvent or generally not paying its debts as they become due, and (C) the execution, delivery and performance by SN Parent of this SN Parent Guaranty has been duly and validly authorized and approved by all necessary corporate action on the part of SN Parent, and this SN Parent Guaranty constitutes the legal, valid and binding obligation of SN Parent, enforceable against SN Parent in accordance with its terms.

15.23 Liability of SN Parties. Notwithstanding anything to the contrary in this Agreement, SN and UnSub shall be jointly and severally liable for all obligations and Liabilities of UnSub under this Agreement.
