Seller shall be entitled to the proceeds from the sale of all oil, gas, casinghead gas, condensate, distillate and other liquid and gaseous hydrocarbons of every kind or description (“Hydrocarbons”) produced from or attributable to the Property before the Effective Time. If, on the Effective Time, Hydrocarbons produced from or attributable to the Property before the Effective Time are stored in any Lease or Unit stock tanks (the “Stock Tank Oil”), or in gathering lines or production facilities upstream of the sale or custody transfer meters (or other applicable point at which the transfer of title actually occurs) of the purchaser or processor of Hydrocarbon production from or attributable to the Property (the “Pipeline Inventory”), Buyer shall purchase from Seller the Stock Tank Oil and the Pipeline Inventory at the actual weighted average price received for Hydrocarbons sold from such stock tanks and pipeline sales points during the full calendar month preceding the Effective Time. If no Hydrocarbons were sold in the preceding month, the actual weighted average price received in the most recent preceding month in which sales occurred shall be used. Buyer will pay Seller for the Stock Tank Oil and Pipeline Inventory as an adjustment to the Purchase Price, as provided in Section 2.2 and Section 2.3. The Stock Tank Oil and the Pipeline Inventory will be determined as of the Effective Time. Absent manifest error, Seller and Buyer will accept the Lease or Unit operator’s tank gauge readings, meter tickets or other inventory records of the Stock Tank Oil and Pipeline Inventory.

1.3.2 Production After the Effective Time. After Closing, Buyer shall be entitled to the proceeds from the sale of all Hydrocarbons produced from or attributable to the Property on and after the Effective Time.

Subject to any continuing sale obligations under the Related Contracts, Buyer may sell Hydrocarbons produced from or attributable to the Property on and after the Closing Date as it deems appropriate.

ARTICLE 2

CONSIDERATION

2.1 Purchase Price and Performance Deposit.

2.1.1 Purchase Price. Buyer will pay Seller Eight Hundred, Fifty-Five Million Dollars ($855,000,000) for the Property (the “Purchase Price”). The Purchase Price shall be adjusted as set forth in this Agreement (the Purchase Price as so adjusted, the “Adjusted Purchase Price”).

2.1.2 Performance Deposit. Upon execution of this Agreement, Buyer shall deliver to Citibank, N.A. (“Escrow Agent”) to the account (the “Escrow Account”) specified in the Escrow Agreement dated as of the date hereof by and among the parties and the Escrow Agent (“Escrow Agreement”), a form of which is attached hereto as Exhibit C, as a performance deposit Fifty Million Dollars ($50,000,000) (such amount plus any interest earned thereon, the “Performance Deposit”). The Performance Deposit shall be held by Escrow Agent pursuant to the terms of this Agreement and the Escrow Agreement. The Performance Deposit is solely to ensure the performance of Buyer’s obligations under this Agreement. If Closing occurs, the Performance Deposit shall be (a) applied as part of the payment of the Adjusted Purchase Price, and the amount of the Adjusted Purchase Price otherwise payable by Buyer at the Closing shall be reduced by that amount, (b) reclassified at Closing to become a portion of the Holdback Amount, and (c) retained by the Escrow Agent as provided for in Section 2.4. If Closing does not occur, the parties shall instruct the Escrow Agent to release the Performance Deposit to Seller or Buyer pursuant to the applicable provision of Section 11.15 and the Escrow Agreement.

2.2 Adjustments at Closing.

2.2.1 Preliminary Settlement Statement. At Closing, the Purchase Price will be adjusted as set forth in Section 2.1.2, Section 2.2.2 and Section 2.2.3. No later than three (3) Business Days prior to the Closing Date, Seller will provide Buyer a preliminary settlement statement (the “Preliminary Settlement Statement”) identifying all adjustments known by Seller at the time of the preparation of the Preliminary Settlement Statement to be made at Closing. Seller and Buyer acknowledge that some items in the Preliminary Settlement Statement may be estimates or otherwise subject to change in the Final Settlement Statement.

2.2.2 Upward Adjustments. The Purchase Price will be increased by the following (“Upward Adjustments”):

(a) Seller’s share of all actual production, maintenance and operating costs and expenses, overhead charges under applicable operating agreements and capital expenditures paid or incurred by Seller in connection with the ownership or operation of the Property in the ordinary course (including, without limitation, royalties, minimum royalties, rentals, and prepaid charges), to the extent they are attributable to the Property for periods on and after the Effective Time; provided, however, that for the period of time between the Effective Time and the Closing Date, with respect to those portions of the Property for which no operating agreement is in place, the upward adjustment shall include a charge for overhead in the amount of One Thousand Dollars ($1,000) per Well per month; provided, however, further that, such amounts shall not include any amounts with respect to which it has been determined that Buyer is entitled to receive indemnification from Seller pursuant to Section 8.4 or with respect to any expense of Seller related to any Adverse Environmental Conditions or cure of any Title Defect or cure of any breach of Seller’s representations or warranties hereunder;

(b) the amount of all Asset Taxes prorated to Buyer in accordance with Section 9.2.1 but paid or payable by Seller (excluding, for the avoidance of doubt, any Asset Taxes that were withheld or deducted from the gross amount paid or payable to Seller in connection with a transaction to which Section 2.2.3(c) applies, and therefore were taken into

account in determining the “proceeds received” by Seller for purposes of applying Section 2.2.3(c) with respect to such transaction);

(c) (i) Seller’s share of any proceeds from the sale of Hydrocarbons produced from or attributable to the Property and other income from the Property received by Buyer, to the extent they are attributable to the ownership or operation of the Property before the Effective Time, and (ii) the value of any merchantable Stock Tank Oil and Pipeline Inventory (as determined in accordance with Section 1.3.1) less all applicable royalties and Taxes;

(d) to the extent that Seller’s interest in any of the Xxxxx is underproduced with respect to any Hydrocarbons as of the Effective Time, the sum of: (i) with respect to gaseous Hydrocarbons, an amount equal to the product of (A) the underproduced volumes, multiplied by (B) $2.64 per MMBtu; and (ii) with respect to liquid Hydrocarbons, an amount equal to the product of (A) the underproduced volumes multiplied by (B) $46.54 per Bbl; and

(e) any other increases in the Purchase Price specified in this Agreement or otherwise agreed in writing between Seller and Buyer prior to or at Closing.

2.2.3 Downward Adjustments. The Purchase Price will be decreased by the following (“Downward Adjustments”):

(b) the amount of all Asset Taxes prorated to Seller in accordance with Section 9.2.1 but paid or payable by Buyer;

(c) Seller’s share (Buyer’s share after Closing) of any proceeds from the sale of Hydrocarbons (i) produced from or attributable to the Property and other income attributable to the Property and actually received by Seller, to the extent they are attributable to the ownership or operation of the Property on or after the Effective Time and (ii) with respect to merchantable Stock Tank Oil and Pipeline Inventory for which Seller received an adjustment to the Purchase Price pursuant to Section 2.2.2(c)(ii);

(d) the Allocated Value of any Property that is excluded from the Closing pursuant to Section 5.5;

(e) all reductions to the Purchase Price for Title Defects, Environmental Defects, Casualty Losses and Government Takings pursuant to Section 5.3, Section 5.6, and Section 5.7, as applicable;

(f) an amount equal to the Suspense Funds, as provided in Section 11.2;

(g) to the extent that Seller’s interest in any of the Xxxxx is overproduced with respect to any Hydrocarbons as of the Effective Time, the sum of: (i) with respect to gaseous Hydrocarbons, an amount equal to the product of (A) the overproduced volumes multiplied by (B) $2.64 per MMBtu; and (ii) with respect to liquid Hydrocarbons, an amount equal to the product of (A) the overproduced volumes multiplied by (B) $46.54 per Bbl; and

(h) any other decreases in the Purchase Price specified in this Agreement or otherwise agreed in writing between Seller and Buyer.

2.3 Adjustments After Closing.

2.3.1 Final Settlement Statement. Within ninety (90) days after the Closing Date (the “Final Settlement Date”), Seller will prepare a final settlement statement for the Property containing a final reconciliation of the adjustments to the Purchase Price specified in Section 2.2 (the “Final Settlement Statement”). Seller shall provide or otherwise make available to Buyer such data and information as Buyer reasonably may request supporting the amounts reflected on the Final Settlement Statement to permit Buyer to comment on the Final Settlement Statement. Buyer will have thirty (30) days after receiving the Final Settlement Statement to provide Seller with written exceptions to any items in the Final Settlement Statement that Buyer believes in good faith to be objectionable. All items in the Final Settlement Statement that Buyer does not make a timely written exception within such thirty (30) day review period will be deemed to be conclusively accepted by Buyer.

2.3.2 Payment of Post-Closing Adjustments. Any adjustments to the Purchase Price (including disputed items as if they were undisputed by Buyer) will be offset against each other so that only one payment is required. The party owing payment will pay the other party the net post-Closing adjustment to the Purchase Price within ten (10) days after the expiration of Buyer’s thirty (30) day review period for the Final Settlement Statement. The payment of any disputed items will be subject to the further rights of the parties under Section 2.3.3.

2.3.3 Resolution of Disputed Items. After the completion and delivery of the Final Settlement Statement, the parties shall negotiate in good faith to attempt to reach agreement on the amount due with respect to any disputed items in the Final Settlement Statement. If the parties agree on the amount due with respect to any disputed items, and a payment adjustment is required, the party owing payment will pay the other party within ten (10) days after the parties reach agreement. If the parties are unable to agree on the amount due with respect to any disputed items within thirty (30) days after Seller receives Buyer’s written exceptions to the Final Settlement Statement, then the disputed items shall be exclusively and finally resolved by arbitration to be conducted in Fort Worth, Texas, by a nationally-recognized independent accounting firm selected by: (i) mutual agreement of Buyer and Seller; or (ii) absent such agreement, by the Dallas office of the American Arbitration Association (the “Accounting Consultant”). The Accounting Consultant shall not have been engaged to provide substantial work by any party or its Affiliates within the five (5) year period preceding the arbitration. The Accounting Consultant, once appointed, shall have no ex parte communications with any of the parties concerning the determination required hereunder. All communications between any party or its Affiliates and the Accounting Consultant shall be conducted in writing, with copies sent

simultaneously to the other party in the same manner, or at a meeting or conference call to which the representatives of both parties have been invited and of which such parties have been provided at least five (5) days’ notice. Within ten (10) days of appointment of the Accounting Consultant, each of Seller and Buyer shall present the Accounting Consultant with its position with respect to the disputed items, and all other supporting information that it desires, with a copy to the other party. The Accounting Consultant shall also be provided with a copy of this Agreement. Within thirty (30) days after receipt of such materials and after receipt of any additional information required by the Accounting Consultant, the Accounting Consultant shall make its determination, which shall be in accordance with the terms of this Agreement and shall be within the disputed range, and such determination shall be final and binding upon the parties, without right of appeal, absent manifest error. The Accounting Consultant 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. Seller shall bear one-half (1/2) and Buyer shall bear one-half (1/2) of the costs and expenses of the Accounting Consultant.

2.3.4 Further Revenues and Expenses. After the completion of the post-Closing adjustments under this Section 2.3: (a) if either party receives revenues that belong to the other party under this Agreement, the party receiving the revenues agrees to promptly remit those revenues to the other party; and (b) if either party pays expenses that are the responsibility of the other party under this Agreement, then the party on whose behalf the expenses were paid agrees to promptly reimburse the other party for the expenses paid on its behalf upon receiving reasonably satisfactory evidence of such payment. However, neither party will be obligated to reimburse the other party for any such expense in excess of Ten Thousand Dollars ($10,000) unless it has been consulted about that expense prior to payment.

2.4 Post-Closing Escrow. At Closing, a portion of the Purchase Price equal to Eighty-Five Million Dollars ($85,000,000) less the Performance Deposit (the “Closing Escrow Amount”) will be delivered by Buyer to the Escrow Agent to serve along with the Performance Deposit as security in support of the indemnification obligations of Seller pursuant to Section 8.4. For purposes of this Agreement and the Escrow Agreement, the “Holdback Amount” shall equal the Closing Escrow Amount delivered by Buyer to the Escrow Agent at Closing plus the Performance Deposit. The Holdback Amount, together with the interest earned thereon from and after the Closing Date, is referred to herein as the “Escrow Fund.” The Escrow Fund shall be held in the Escrow Account and released in accordance with the provisions of this Section 2.4 and the Escrow Agreement. From time to time after Closing, the Escrow Agent shall be jointly instructed in writing by Seller and Buyer to release all or portions of then-remaining Escrow Fund to Buyer or to Seller, in each case, as provided below in this Section 2.4.

2.4.1 Escrow Claims. If at any time prior to the date that is twelve (12) months after the Closing Date (such time period, the “Holdback Period”) there are amounts remaining in the Escrow Fund, to the extent that Seller does not promptly (and in any event within thirty (30) days after receipt of a Claim Notice from Buyer) reimburse or pay Buyer for any amounts to which Buyer is entitled with respect to such Claim Notice pursuant to Section 8.4, then Buyer shall be entitled to deliver to Seller written notice (an “Escrow Claim Notice”), which notice shall specify with particularity the nature and amount of Buyer’s claim pursuant to Section 8.4 as set forth in the Claim Notice (the “Escrow Claim”), including specific details of and a specific

basis under this Agreement entitling Buyer to such Escrow Claim. For the avoidance of doubt, Seller may require that Buyer first recover all amounts to which Buyer is entitled hereunder from the Escrow Account to the extent of the Escrow Fund then available if Seller delivers to Buyer and the Escrow Agent executed irrevocable written instructions that instruct the Escrow Agent to deliver to Buyer an amount from the Escrow Fund in respect of such Escrow Claim equal to the lesser of (a) the amount of such Escrow Claim, or (b) the amount of the Escrow Fund then remaining in the Escrow Account.

2.4.2 Resolution of Escrow Claims. Upon final resolution of any such Escrow Claim pursuant to the mutual written agreement of Buyer and Seller or as determined by a final, non-appealable judgment of a court of competent jurisdiction in accordance with Section 11.11, if Buyer is entitled to all or any portion of the Escrow Fund then-remaining, then Seller and Buyer shall provide joint written instructions to the Escrow Agent to disburse to Buyer the amount set forth in such joint written instruction, which amount shall be that portion of the Escrow Fund then-remaining in the Escrow Account at such time as would satisfy such Escrow Claim as so finally resolved.

2.4.3 Partial Release of Escrow Fund. On the first Business Day following the date that is six (6) months after the Closing Date, Seller and Buyer shall provide joint written instructions to the Escrow Agent to release to Seller fifty percent (50%) of the amount then-remaining in the Escrow Fund, excluding those amounts attributable to any then-outstanding Escrow Claim for which Buyer has in good faith provided an Escrow Claim Notice to Seller in accordance with Section 2.4.1 that have not been previously satisfied, and, with respect to each such outstanding Escrow Claim, each amount attributable thereto (to the extent sufficient funds remain in the Escrow Fund as of such date and if there are insufficient funds remaining in the Escrow Fund as of such date, the entirety of the funds remaining in the Escrow Fund as of such date) shall remain part of the Escrow Fund in the Escrow Account until final resolution of such Escrow Claim pursuant to the mutual written agreement of Buyer and Seller or as determined by a final, non-appealable judgment of a court of competent jurisdiction in accordance with Section 11.11.

2.4.4 Release of Remaining Escrow Fund. On the first Business Day following the expiration of the Holdback Period, Seller and Buyer shall provide joint written instructions to the Escrow Agent to release to Seller any amounts then-remaining in the Escrow Fund, excluding those amounts attributable to any then-outstanding Escrow Claim for which Buyer has in good faith provided an Escrow Claim Notice to Seller in accordance with Section 2.4.1 that have not been previously satisfied, and, with respect to each such outstanding Escrow Claim, each amount attributable thereto (to the extent sufficient funds remain in the Escrow Fund as of such date and if there are insufficient funds remaining in the Escrow Fund as of such date, the entirety of the funds remaining in the Escrow Fund as of such date) shall remain part of the Escrow Fund in the Escrow Account until final resolution of such Escrow Claim pursuant to the mutual written agreement of Buyer and Seller or as determined by a final, non-appealable judgment of a court of competent jurisdiction in accordance with Section 11.11.

2.5 Payment Method. Unless the parties otherwise agree in writing, all payments under this Agreement will be by wire transfer in immediately available funds to an account designated by the party receiving payment.

2.6 Principles of Accounting. The Preliminary Settlement Statement and Final Settlement Statement will be prepared in accordance with accounting principles generally accepted in the petroleum industry, consistently applied, and applicable laws, rules and regulations.

2.7 Reporting Value of the Property. Neither party will take any position in preparing financial statements, Tax Returns, reports to shareholders or governmental authorities, or otherwise, that is inconsistent with the allocation of value for the Property in Exhibit B, unless the parties otherwise agree in writing. The value assigned to each portion of the Property in Exhibit B is hereafter referred to as the “Allocated Value” of that portion of the Property.

2.8 Section 1031 Exchange. Seller and Buyer hereby agree that Buyer shall have the right at any time prior to Closing to assign all or a portion of its rights under this Agreement to a “Qualified Intermediary” (as that term is defined in Section 1.1031(k) 1(g)(4)(v) of the Treasury Regulations) in order to accomplish the transaction in a manner that will comply, either in whole or in part, with the requirements of a like kind exchange pursuant to Section 1031 of the Internal Revenue Code of 1986, as amended (the “Code”). Likewise, Seller shall have the right at any time prior to Closing to assign all or a portion of its rights under this Agreement to a Qualified Intermediary for the same purpose. In the event a party assigns its rights under this Agreement pursuant to this Section 2.8, such party agrees to notify the other parties in writing of such assignment at or before Closing. If Seller assigns its rights under this Agreement for this purpose, Buyer agrees to: (a) consent to Seller’s assignment of its rights in this Agreement; and (b) pay the Purchase Price into a qualified escrow or qualified trust account at Closing as directed in writing. If Buyer assigns its rights under this Agreement for this purpose, Seller agrees to: (i) consent to Buyer’s assignment of its rights in this Agreement; (ii) accept the Purchase Price from the qualified escrow or qualified trust account at Closing; and (iii) at Closing, convey and assign directly to Buyer the Property upon satisfaction of the other conditions to Closing and other terms and conditions hereof. Seller and Buyer acknowledge and agree that any assignment of this Agreement to a Qualified Intermediary shall not delay the Closing, shall not release any party hereto from any of its respective liabilities and obligations (including indemnity obligations) to the other parties hereto under this Agreement, and that no party represents to any other party that any particular Tax treatment will be given to a party as a result thereof.

To be effective, such notice must be in writing and must include: (a) a reasonably detailed description of the alleged Adverse Environmental Condition; (b) the Property affected; (c) the Allocated Value of the Property subject to the alleged Adverse Environmental Condition; (d) data and information in Buyer’s and/or the Inspector’s possession reasonably necessary for Seller to substantiate and verify the existence of the alleged Adverse Environmental Condition, including, without limitation, a copy of the Inspection Results, limited to that portion of the Property subject to the Adverse Environmental Condition; and (e) the estimated Environmental Defect Value attributable thereto. The “Environmental Defect Value” attributable to any Adverse Environmental Condition shall be the estimated cost of any remediation or other corrective action reasonably designed to meet the least restrictive standard or remedy that fully complies with applicable Environmental Laws (including where applicable, engineering or institutional controls or any less stringent standards or remedies resulting from site-specific risk assessments)

based on the current nature of use of the relevant facility or property, on a current cost basis, net to Seller’s interest in the relevant Property (the “Standard”). The term “Adverse Environmental Condition” means and includes, with respect to any portion of the Property: (a) the failure of the Property (or Seller or any of its Affiliates with respect to the Property or operation of the Property) to be in compliance with applicable Environmental Laws; (b) the Property (or Seller or any of its Affiliates with respect to the Property or operation of the Property) being subject to any uncured notices of violations of or noncompliance with any applicable Environmental Laws; or (c) any hazardous materials or other environmental pollution have been released and are present at any portion of the Property in violation of Environmental Laws or for which any remediation or corrective action is required (or if known, would be required) under any Environmental Law. The term “Environmental Laws” means any statute, law, common law, ordinance, rule, regulation, code, order, injunction or decree issued by any federal, state or local governmental authority in effect on or before the Execution Date relating to the prevention of pollution, the preservation and restoration of environmental quality, the protection of human health, wildlife or environmentally sensitive areas, the remediation of contamination, the generation, handling, treatment, storage, transportation, disposal or release into the environment of waste materials, or the regulation of or exposure to hazardous or toxic substances, including, without limitation, the federal Oil Pollution Act (OPA), the federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), the federal Resource Conservation and Recovery Act (RCRA), the federal Clean Water Act, the Toxic Substances Control Act (TSCA), the Hazardous Materials Transportation Act (49 USC § 5101 et seq.), the Texas Health and Safety Code, the Texas Water Code (TWC), the Texas Natural Resources Code, and the federal, state and local rules, regulations, ordinances, orders and governmental directives implementing such statutes. Subject to and without limiting Seller’s indemnity obligations under this Agreement and Buyer’s remedies for the breach of the representation of Seller set forth in Section 3.2.13, Buyer shall be deemed to have conclusively waived, and Seller shall have no liability for, any Adverse Environmental Condition of which Seller has not been given timely notice in accordance with the requirements of this Section 5.3.3.

5.3.4 Remedies for Uncured, Unwaived Adverse Environmental Conditions.

(a) For each Adverse Environmental Condition identified prior to the Environmental Claim Date as provided in Section 5.3.3, Seller may elect, at its sole option, with notice to Buyer at any time on or prior to three (3) Business Days before Closing, and without prejudice to the parties continuing right to dispute the existence or nature of or cost to remediate such Adverse Environmental Condition to the Standard, to:

(i) with the written consent of Buyer, remediate the asserted Adverse Environmental Condition to the Standard, with no adjustment to the Purchase Price at Closing, which remediation effort may continue after Closing; provided, however, that until the Adverse Environmental Condition is remediated to the Standard, Seller shall INDEMNIFY, DEFEND AND HOLD HARMLESS Buyer from and against all Claims related to such Adverse Environmental Condition, provided, further, however, that such indemnity shall terminate as to each particular Adverse Environmental Condition when the Adverse Environmental Condition is remediated to the Standard;

(ii) subject to the remaining provisions of this Agreement,

(A) if the Environmental Defect Value is less than the Allocated Value of the affected Property, transfer the affected Property to Buyer at Closing and reduce the Purchase Price by the Environmental Defect Value as agreed upon by Seller and Buyer or determined pursuant to Section 5.3.5 or (B) if the Environmental Defect Value is greater than the Allocated Value of the affected Property retain the affected Property and reduce the Purchase Price by the Allocated Value thereof; or

(iii) retain the affected Property and reduce the Purchase Price by the Allocated Value thereof.

Should Seller fail to timely exercise any of the three (3) options stated above, or if there is a dispute as to an Adverse Environmental Condition subject to resolution under Section 5.3.5, then Section 5.3.4(a)(ii) shall apply.

(b) Notwithstanding anything to the contrary in this Section 5.3, Buyer shall have no remedy hereunder for any Adverse Environmental Condition unless: (i) the Environmental Defect Value for such Adverse Environmental Condition exceeds One Hundred Thousand Dollars ($100,000) net to Seller’s interest in the allegedly affected portion of the Property (the “Environmental Threshold”), in which event the value of such defect will be taken into account from first dollar; and (ii) the aggregate Environmental Defect Values for the Adverse Environmental Conditions with Environmental Defect Values exceeding the Environmental Threshold exceeds two and one-half percent (2.5%) of the Purchase Price, and then only to the extent such amount exceeds two and one-half percent (2.5%) of the Purchase Price.

5.3.5 Adverse Environmental Condition Disputes.

(a) Without prejudice to either party’s position as to the existence or nature of an Adverse Environmental Condition or the cost to remediate an Adverse Environmental Condition to the Standard, Seller and Buyer shall attempt to agree prior to the Closing Date on: (i) the existence of any Adverse Environmental Condition; (ii) Seller’s remediation of any Adverse Environmental Condition to the Standard; and (iii) the Environmental Defect Value associated with any Adverse Environmental Conditions. If Seller and Buyer are unable to agree on any of the above (collectively or individually, as applicable, the “Disputed Environmental Matters”) prior to the Closing Date, an amount equal to the average of (A) the Environmental Defect Value claimed in good faith by Seller and (B) the Environmental Defect Value claimed in good faith by Buyer, shall be used to determine the Purchase Price to be paid at Closing, and the Disputed Environmental Matters shall be exclusively and finally resolved by expert determination pursuant to Section 5.3.5(b).

(b) Within ten (10) days following the Closing Date, all Disputed Environmental Matters shall be submitted to an environmental consultant with at least ten (10) years’ experience in oil and gas environmental matters as selected by: (i) mutual agreement of Buyer and Seller; or (ii) absent such agreement during such ten (10) day period, by the Dallas office of the American Arbitration Association (the “Environmental Consultant”). The Environmental Consultant shall not have been employed by any party or its Affiliates within the five (5) year period preceding the arbitration. The Environmental Consultant, once appointed,

shall have no ex parte communications with any of the parties concerning the determination required hereunder. All communications between any party or its Affiliates and the Environmental Consultant shall be conducted in writing, with copies sent simultaneously to the other party in the same manner, or at a meeting or conference call to which the representatives of both Seller and Buyer have been invited and of which such parties have been provided at least five (5) days’ notice. Within ten (10) days of appointment of the Environmental Consultant, each of Seller and Buyer shall present the Environmental Consultant with a written statement of its position on the Disputed Environmental Matters, including a written statement of its position with respect to any disputes regarding: (x) the existence of any Adverse Environmental Condition; (y) the proposed remediation of any Adverse Environmental Condition to the Standard; and (z) the estimated Environmental Defect Value, in each case, as applicable, together with all other supporting information that it deems relevant, with a copy to the other party. The Environmental Consultant shall also be provided with a copy of this Agreement. Within forty-five (45) days after receipt of such materials and after receipt of any additional information required by the Environmental Consultant, the Environmental Consultant shall make its determination, which shall be final and binding upon all parties, without right of appeal, absent manifest error. In making its determination, the Environmental Consultant shall be bound by the rules set forth in this Section 5.3. In no event shall the Environmental Consultant select an amount lower than the amount proposed by Seller nor higher than the amount proposed by Buyer, as applicable. The Environmental Consultant shall act as an expert for the limited purpose of determining: (A) the existence of any Adverse Environmental Condition in dispute; (B) whether any Adverse Environmental Condition has been remediated to the Standard; and (C) the specific disputed Environmental Defect Values. The Environmental Consultant may not award damages, interest or penalties to any party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Seller shall bear one-half (1/2) and Buyer shall bear one-half (1/2) of the costs and expenses of the Environmental Consultant.

5.3.6 Exclusive Remedy. Subject to and without limiting Seller’s indemnity obligations under this Agreement and Buyer’s remedies for the breach of the representation of Seller set forth in Section 3.2.13, the remedies set forth in Section 8.4.1 with respect to Section 3.2.13 and this Section 5.3 are the sole and exclusive remedies of Buyer with respect to any Adverse Environmental Condition (and all Environmental Obligations arising out of any such Adverse Environmental Condition) attributable to the ownership or operation of the Property by Seller or any of its parent, subsidiary or affiliated entities of any tier prior to the Effective Time, or the condition of the Property prior to the Effective Time, regardless of whether Buyer notifies Seller of any such Adverse Environmental Condition. Subject to and without limiting Seller’s indemnity obligations under this Agreement and Buyer’s remedies for the breach of the representation of Seller set forth in Section 3.2.13, Seller shall have no liability to Buyer for any such Adverse Environmental Condition (or its related Environmental Obligations) if Buyer fails to notify Seller as provided in Section 5.3.3.

5.4 Bonding Requirements. Buyer agrees to promptly purchase and post any and all bonds, supplemental bonds or other securities which may be required of it pursuant to all applicable federal, state and local laws, rules and regulations.

5.5 Preferential Rights and Consents to Assign.

5.5.1 Notices to Holders.

(a) If Seller’s right to convey any of the Property to Buyer is subject to third-Person preferential purchase rights, rights of first refusal, or similar rights (collectively, “Preferential Rights”), or third-Person consents to assign or similar rights, excluding consents ordinarily obtained after Closing (collectively, “Consents”), then, as soon as reasonably practical after the Execution Date, but in any event, within ten (10) days following the Execution Date, Seller shall: (i) notify the holders of the Preferential Rights and Consents identified on Schedule 3.2.3 (or any Preferential Rights or Consents subsequently identified that are not on Schedule 3.2.3) or (pursuant to a notice in material compliance with the contractual provisions of such Preferential Rights and Consents) that it intends to transfer the Property to Buyer; (ii) provide the holders of such Preferential Rights and Consents with any information about the transfer of the Property to which they are entitled according to the contractual provisions of such Preferential Rights and Consents; (iii) in the case of such Preferential Rights, request the holders of such Preferential Rights to waive their right to purchase the affected Property and (iv) in the case of such Consents, request the holders of such Consents to consent to the assignment of the affected Property to Buyer.

(b) Before Closing, Seller shall notify Buyer whether: (i) any Preferential Rights are exercised or waived; (ii) any Consents are granted or denied or cannot be obtained before Closing; or (iii) the requisite time periods have elapsed and any Preferential Rights are deemed waived or Consents deemed given by the lapse of such requisite time periods under the applicable agreements.

(c) If any Preferential Rights are exercised, the portion of the Property burdened by the exercised Preferential Right shall be excluded, and the Purchase Price shall be reduced by the Allocated Value of the excluded portion of the Property. Seller will not be liable to Buyer if any Preferential Rights are exercised, or any Consents are denied, except for the Purchase Price adjustment herein provided. Buyer shall be obliged to close on all other portions of the Property, subject to Section 5.5.2 and Buyer’s termination right in Section 5.8.

5.5.2 Remedies.

(a) Preferential Rights. Before Closing, if any Preferential Right has not been waived or exercised in accordance with its terms, and the time period for such exercise has not expired, the parties shall proceed to Closing as to the portion of the Property burdened by such Preferential Rights without adjustment to the Purchase Price, subject to the further obligations of Buyer and Seller set forth in this Section 5.5.2(a) in the event such Preferential Rights are ultimately exercised after Closing. After Closing, if: (i) any holder of Preferential Rights has alleged or alleges improper notice of sale; (ii) Seller or Buyer discover, or any third Person alleges, the existence of additional Preferential Rights; or (iii) the time period for exercise of any Preferential Right did not expire before Closing, then, in each case, Seller and Buyer will attempt to obtain waivers of such Preferential Rights. If Seller and Buyer are unable to obtain waivers of such Preferential Rights, and such Preferential Rights are not deemed waived, or the third Person ultimately establishes and exercises its rights, then Buyer shall re-convey the

affected Property (pursuant to an assignment containing a special warranty of title only) to Seller in order that Seller may satisfy all such Preferential Rights obligations and Seller shall simultaneously with such reconveyance refund to Buyer the Allocated Value of such Property.

(b) Consents.

(i) Before Closing, Seller shall use reasonable efforts (which shall not require the payment of money to third Persons) to obtain all Consents. If Seller is unable to obtain a Consent (other than a Hard Consent), then Seller and Buyer shall proceed to Closing as to the portion of the Property affected by the un-obtained Consent without adjustment to the Purchase Price, subject to the further obligations of Seller and Buyer set forth in this Section 5.5.2(b). After Closing, Seller shall attempt to obtain any un-obtained Consents (which shall not require the payment of money to third Persons), including Consents alleged by third Persons or identified after Closing, and Buyer shall provide reasonable assistance to Seller. If Seller is unable to obtain such Consents on or before the Final Settlement Date, then Buyer shall retain ownership of the affected portion of the Property.

(ii) If Seller fails to obtain a Consent prior to Closing and the failure to obtain such consent would cause (or give the lessor or grantor the right to cause) (A) the assignment of the portion of the Property affected thereby to Buyer to be void or (B) the termination of the Lease affected thereby under the express terms thereof (each, a “Hard Consent”), then, in each such case, the affected portion of the Property shall be excluded from the Property to be acquired by Buyer at Closing hereunder and the Purchase Price shall be reduced by the Allocated Value of the portion of the Property so excluded. In the event that a Hard Consent (with respect to any applicable portion of the Property excluded pursuant to this Section 5.5.2(b)(ii) that was not obtained prior to Closing is obtained prior to the Final Settlement Date, then, Buyer shall purchase, within ten (10) days after such Hard Consent is obtained, such portion of the Property so excluded as a result of such previously un-obtained Hard Consent under the terms of this Agreement for the amount (if any) by which the Purchase Price was reduced at Closing due to the exclusion of such portion of the Property (as such amount is appropriately adjusted in accordance with Section 2.2 with respect to such portion of the Property), and Seller shall assign to Buyer such portion of the Property pursuant to an assignment, in a form substantially similar to the Assignment.

(c) Limitation of Liability. Except to the extent Seller fails to fulfill its obligations set forth above in this Section 5.5 and subject to Buyer’s remedies for Seller’s breach of the representations and warranties in Section 3.2.3, Buyer shall DEFEND, INDEMNIFY AND HOLD HARMLESS Seller from and against all Claims, actions, causes of action whatsoever that arise out of the failure to obtain waivers of Preferential Rights or the failure to obtain Consents with respect to any transfer by Seller to Buyer of any portion of the Property and with respect to subsequent transfers WHETHER OR NOT SUCH CLAIMS, ACTIONS OR CAUSES OF ACTION ARISE OUT OF THE NEGLIGENCE OF SELLER (INCLUDING SELLER’S SOLE, SIMPLE, CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE, BUT EXPRESSLY EXCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SELLER).

5.6 Title Defects.

5.6.1 Certain Definitions.

(a) Title Defects. For the purposes of this Agreement, a “Title Defect” means any (1) lien, mortgage, deed of trust, pledge, charge, collateral assignment, security interest or other encumbrance or surface restriction of any kind affecting Seller’s title or interest in the Property; or (2) impairment, encroachment, irregularity, defect in or dispute concerning Seller’s title to the Property that would:

(i) reduce Seller’s Net Revenue Interest in the currently producing formations of any Well below that set forth in Exhibit A, Schedule 2 for such Well;

(ii) increase Seller’s Working Interest in the currently producing formations of any Well above that set forth in Exhibit A, Schedule 2 for such Well, without a corresponding and proportionate increase in Seller’s Net Revenue Interest;

(iii) reduce the number of net mineral acres attributable to Seller’s interest in a Lease, insofar as such Lease affects the Target Depth, below that set forth in Exhibit A, Schedule 1 for such Lease; or

(iv) reduce Seller’s Net Revenue Interest in a Lease, insofar as such Lease affects the Target Depth, below that set forth in Exhibit A, Schedule 1 for such Lease.

For purposes of this Section 5.6, the “Target Depth” shall refer to the stratigraphic equivalent of the interval shown from 9,515 feet to 12,447 feet on the log of the Petrohawk Operating Company—Oxy Fee “24” Lease, Well No. 1 (API No. 42-389-32637), located in Section 00, Xxxxx X00, XXX Xxxxxx, X-0000, Xxxxxx County, Texas, unless otherwise limited on Exhibit A, Schedule 1. For purposes of this Section 5.6, a “net mineral acre” shall mean as to each parcel or tract of land burdened by a Lease, the product of (a) the number of acres of land that are in such parcel or tract (i.e., gross acres), multiplied by (b) the lessor’s undivided interest in the lands covered by such Lease, multiplied by (c) the Seller’s undivided interest in such Lease (provided, however, if items (b) and (c) of the definition vary as to different areas within any tracts or parcels burdened by such Lease, a separate calculation shall be performed with respect to each such area). Notwithstanding the foregoing, the following shall not be considered Title Defects: (1) any matter based solely on lack of information or documents in Seller’s files; (2) any failure to record federal Leases or assignments thereof in county records; (3) any Adverse Environmental Condition, Production Imbalances set forth on Schedule 3.2.5, Permitted Encumbrance, Consents set forth on Schedule 3.2.3 or Preferential Rights set forth on Schedule 3.2.3; (4) defects arising out of lack of survey (unless required by applicable law); (5) defects that have been cured by applicable laws of limitations or prescription; (6) defects in the chain of title consisting of the mere failure to recite marital status in a document or omissions of successions of heirship or estate proceedings, unless Buyer provides affirmative evidence that such failure or omission has resulted in another Person’s superior claim of title; and (7) the expiration of the primary term of any Lease in effect on the Effective Time.

(b) Permitted Encumbrances. The term “Permitted Encumbrance” means:

(i) any materialmans’, mechanics’, repairmans’, employees’, contractors’, operators’ or other similar liens, security interests or charges for liquidated amounts arising in the ordinary course of business incidental to construction, maintenance, development, production or operation of the Property, or the production or processing of Hydrocarbons therefrom, that are not yet delinquent;

(ii) any liens for Taxes not yet delinquent;

(iii) any liens or security interests created by law or reserved in oil, gas and/or mineral leases for royalty, bonus or rental or for compliance with the terms of leases;

(iv) any easements, rights-of-way, servitudes, permits, licenses, surface leases and other rights with respect to surface operations, to the extent such matters do not interfere in any material respect with Seller’s ownership or operation of any portion of the Property;

(v) all royalties, overriding royalties, net profits interests, carried interests, reversionary interests and other burdens, to the extent that the net cumulative effect of such burdens, as to a particular Property, does not operate to reduce Seller’s Net Revenue Interest in such Property below that set forth in the applicable Schedule to Exhibit A;

(vi) to the extent not currently triggered, conventional rights of reassignment arising upon surrender or abandonment of any Property;

(vii) rights reserved to or vested in any governmental authority to control or regulate any of the Xxxxx and all applicable laws, rules, regulations and orders of such authorities, in each case, so long as the same have not been applied to decrease Seller’s Net Revenue Interest in any Well below that set forth in Exhibit A, Schedule 2 for such Well or increase Seller’s Working Interest in any Well above that set forth in Exhibit A, Schedule 2 for such Well (without a corresponding and proportionate increase in the Net Revenue Interest for such Well);

(viii) any defects or irregularities in acknowledgements, unless Buyer provides affirmative evidence that such failure or omission has resulted in another Person’s superior claim of title;

(ix) any defects and irregularities arising out of the lack of recorded powers of attorney from corporations or partnerships to execute and deliver documents on their behalf, unless Buyer provides affirmative evidence that such failure or omission has resulted in another Person’s superior claim of title;

(x) any defects or irregularities resulting from prior oil and gas leases, which, on their face, expired more than fifteen (15) years ago and for which there were no

production under such leases which would have maintained such leases beyond their primary term;

(xi) any defects or irregularities arising out of mortgages, deeds of trust, and other encumbrances, which, by their terms, matured more than fifteen (15) years ago without any (A) extension of said maturity date or (B) cause of action on any underlying debt, but which have not been released of record;

(xii) defects or irregularities in title, which, for a period of fifteen (15) years or more have not delayed or prevented Seller (or its predecessors) from receiving its Net Revenue Interest from any Well or Lease and for which no claim was or has been made by any third Person;

(xiii) any liens or security interests for which Seller obtains a release on or prior to the Closing Date; or

(xiv) with respect to non-producing Leases only, defects arising from any outstanding deed of trust or mortgage burdening the interest of a mineral lessor, which has not been subordinated to the lessee’s interest.

(c) Title Benefit. The term “Title Benefit” means any right, circumstance or condition that operates (i) to increase Seller’s Net Revenue Interest in any Well or Lease above that set forth in Exhibit A, Schedule 1 or Exhibit A, Schedule 2 for such Well or Lease, as applicable, and in the case of a Well, without causing a greater than proportionate increase in Seller’s Working Interest for such Well or (ii) to increase the number of net mineral acres attributable to any Lease above that set forth in Exhibit A, Schedule 1.

5.6.2 Notice of Title Defects; Defect Adjustments.

(a) Buyer may review title to the Xxxxx and Leases prior to Closing and Buyer shall have the option, in its sole discretion, to notify Seller in writing of any Title Defect it discovers on or before December 20, 2016 (the “Title Claim Date”). To be effective, such notice shall be in writing and shall include: (i) a reasonably detailed description of the alleged Title Defect(s); (ii) the portion of the Property affected; (iii) the Allocated Value of the portion of the Property subject to the alleged Title Defect(s); (iv) supporting documents in Buyer’s possession reasonably necessary for Seller (as well as any title attorney or examiner hired by Seller) to verify the existence of the alleged Title Defect(s); and (v) the amount by which Buyer reasonably believes the Allocated Value of the applicable portion of the Property is reduced by the alleged Title Defect(s) and the computations and information upon which Buyer’s belief is based. Subject to and without limiting the Special Warranty, Buyer shall be deemed to have conclusively waived, and Seller shall have no liability for, any Title Defects of which Seller has not been given timely notice on or before the Title Claim Date in accordance with the requirements of this Section 5.6.2.

(b) On or before the Title Claim Date, Seller shall have the right, but not the obligation, to deliver to Buyer written notice of any Title Benefits on or prior to the Title Claim Date and such notice shall include: (i) a reasonably detailed description of the Title

Benefit(s); (ii) the Well or Lease affected; (iii) the Allocated Value of the Well or Lease subject to such Title Benefit(s); (iv) supporting documents in Seller’s possession reasonably necessary for Buyer to verify the existence of the alleged Title Benefit(s), and (v) the amount by which Seller reasonably believes the Allocated Value of the affected Well or Lease is increased by the Title Benefit(s) and the computations and information upon which Seller’s belief is based. If Buyer discovers any Title Benefit during its due diligence review, then Buyer shall promptly (but in no event less than five (5) Business Days prior to the Title Claim Date) provide informal written notice of such Title Benefit to Seller on or before the Title Claim Date. Seller shall be deemed to have waived all Title Benefits of which Seller has not given notice in compliance with this Section 5.6.2(b) on or before the Title Claim Date.

(c) Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure or remove on or before the Closing Date any Title Defects of which it has been advised by Buyer prior to the Title Claim Date. If Seller has commenced to cure such a Title Defect prior to the Closing Date and is pursuing that cure diligently, Seller may elect to continue attempting to cure such Title Defect until the Final Settlement Date, but must provide Buyer notice of such election at least two (2) Business Days prior to the Closing Date. If Seller elects to attempt to cure any Title Defects pursuant to this Section 5.6.2(c), at Closing, Buyer shall deposit an amount equal to the Title Defect Value of all such Title Defects (as asserted in good faith by Buyer) into an escrow account established with the Escrow Agent, pursuant to the terms of a mutually agreeable escrow agreement, pending agreement by the Parties that the Title Defect has been cured or resolution under Section 5.6.2(i). Seller’s election to attempt to cure a Title Defect shall not constitute a waiver of Seller’s right to dispute the existence, nature or value of, or cost to cure, the Title Defect.

(d) Seller’s interest in each Well or Lease affected by Title Defects properly reported under Section 5.6.2(a) and not cured prior to the Closing Date shall be assigned to Buyer at Closing subject to all such uncured Title Defects. If Seller has not provided notice under Section 5.6.2(c) of its election to continue attempting to cure a Title Defect, the Purchase Price shall be adjusted by an amount (the “Title Defect Value”) equal to the reduction in the Allocated Value for the affected Well or Lease caused by such Title Defect, as determined pursuant to Section 5.6.2(f). If Seller has provided such notice under Section 5.6.2(c), no Purchase Price reduction shall be made until the Final Settlement Date, at which time, if the Title Defect remains uncured, the Purchase Price shall be reduced by the Title Defect Value. Should the cumulative Title Defect Values with respect to any Well or Lease equal the entire Allocated Value for the affected Property, Buyer shall, within ten (10) days of any such determination, reconvey to Seller all of its rights with respect to such Well or Lease by conveyance without warranty (other than a special warranty of title by, through or under Buyer, but not otherwise) and the Purchase Price shall be decreased in the Final Settlement by the entire Allocated Value for such re-conveyed Well or Lease.

(e) With respect to each Well or Lease affected by Title Benefits reported under Section 5.6.2(b) (or of which Buyer had Knowledge and should have reported under Section 5.6.2(b)), the aggregate Title Defect Value for all Title Defects for which Buyer is entitled to a remedy under Section 5.6.2(d) shall be decreased by an amount (the “Title Benefit Value”) equal to the increase in the Allocated Value for such Well or Lease caused by such Title

Benefits, as determined pursuant to Section 5.6.2(g). The remedy described in this Section 5.6.2(e) shall be Seller’s sole and exclusive remedy with respect to any Title Benefits.

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

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

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

(iii) if the Title Defect is of the type described in Section 5.6.1(a)(2)(i), then the Title Defect Value shall be an amount equal to the Allocated Value for such Well, multiplied by (y) one (1) minus (z) a fraction, the numerator of which is Seller’s actual Net Revenue Interest for such Well in the currently producing formations and the denominator of which is the Net Revenue Interest for such Well set forth in Exhibit A, Schedule 2, provided, however, that if the Title Defect does not affect such Well throughout the entire remaining life of such Well, the Title Defect Value so determined shall be reduced to take into account the applicable time period only;

(iv) if the Title Defect is of the type described in Section 5.6.1(a)(2)(ii), then the Title Defect Value shall be an amount equal to the diminution in value of such Well in the currently producing formations based on the Allocated Value for such Well and resulting from the increase in such Working Interest in the currently producing formations over the life of the Well;

(v) if the Title Defect is of the type described in Section 5.6.1(a)(2)(iii), then the Title Defect Value shall be an amount equal to the product of (y) the Allocated Value of such Lease multiplied by (z) one (1), minus a fraction, the numerator of which is Seller’s actual net mineral acres covered by such Lease (with respect to the Target Depth) and the denominator of which is the net mineral acres for such Lease (with respect to the Target Depth) set forth in Exhibit A, Schedule 1;

(vi) if the Title Defect is of the type described in Section 5.6.1(a)(2)(iv), then the Title Defect Value shall be an amount equal to the product of (y) the Allocated Value of such Lease multiplied by (z) one (1), minus a fraction, the numerator of which is Seller’s actual Net Revenue Interest for such Lease (with respect to the Target Depth) and the denominator of which is the Net Revenue Interest for such Lease (with respect to the Target Depth) set forth in Exhibit A, Schedule 1;

(vii) if the Title Defect is of a type not described above, then, in each case, the Title Defect Value shall be determined by taking into account the Allocated Value of the Well or Lease so affected, the portion of Seller’s interest in the Well or Lease 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 affected Well or Lease, the values placed upon the Title Defect by

Buyer and Seller and such other factors as are necessary to make a proper evaluation; and

(viii) notwithstanding anything to the contrary in this Section 5.6, Buyer shall have no remedy hereunder for any Title Defect unless: (A) the Title Defect Value for such Title Defect exceeds Fifty Thousand Dollars ($50,000) net to Seller’s interest in the relevant Well or Lease (the “Title Defect Threshold”), in which event the value of such defect will be taken into account from first dollar; and (B) the sum of the aggregate Title Defect Values for Title Defects with Title Defect Values exceeding the Title Defect Threshold exceeds two percent (2%) of the Purchase Price, and then only to the extent such amount exceeds two percent (2%) of the Purchase Price.

(g) The Title Benefit Value for any Title Benefit shall be determined as follows:

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

(ii) if the Title Benefit is of the type described in Section 5.6.1(c)(i), then the Title Benefit Value shall be an amount equal to the Allocated Value for such Well or Lease, multiplied by the proportionate increase in such Net Revenue Interest (i.e., the amount by which Seller’s actual Net Revenue Interest is more than the Net Revenue Interest set forth for such Well or Lease on Exhibit A, Schedule 1 or Exhibit A, Schedule 2, divided by the Net Revenue Interest set forth on Exhibit A, Schedule 1 or Exhibit A, Schedule 2, as applicable), provided, however, that if the Title Benefit does not affect such Well or Lease throughout the entire remaining life of such Well or Lease, the Title Benefit Value so determined shall be reduced to take into account the applicable time period only; or

(iii) for any other Title Benefits the Title Benefit Value shall be determined by taking into account the Allocated Value of the Well or Lease so affected, the portion of Seller’s interest in the Well or Lease affected by the Title Benefit, the legal effect of the Title Benefit, the potential economic effect of the Title Benefit over the life of the affected Well or Lease, the values placed upon the Title Benefit by Buyer and Seller and such other factors as are necessary to make a proper evaluation.

(h) Seller and Buyer shall attempt to agree prior to the Closing Date on all: (i) Title Defect Values for Title Defects properly asserted prior to the Title Claim Date that Seller elected not to or was unable to cure (except with respect to Title Defects for which Seller provides notice of its election to continue attempting to cure after the Closing Date under Section 5.6.2(c)); and (ii) Title Benefit Values. If Seller and Buyer are unable to agree by that date, an amount equal to the average (the “Title Defect Value Average”) of (A) the Title Defect Value claimed in good faith by Seller and (B) the Title Defect Value claimed in good faith by Buyer shall be used to determine the Purchase Price to be paid at Closing; and the Title Defect Values and Title Benefit Values in dispute shall be exclusively and finally resolved by expert determination pursuant to Section 5.6.2(i). Likewise, if by the Final Settlement Date, Seller has failed to cure any Title Defects reported prior to the Title Claim Date with respect to which it provided notice of its election to continue attempting to cure under Section 5.6.2(c), and Seller and Buyer have been unable to agree on the Title Defect Values for such Title Defects, the Title

Defect Value Average shall be used in the Final Settlement Statement, and the Title Defect Values in dispute shall be exclusively and finally resolved by expert determination pursuant to Section 5.6.2(i).

(i) During the ten (10) Business Day period following the Closing Date or following the Final Settlement Date, as applicable, disputed Title Defects, Title Benefits, cures, and Title Defect Values and Title Benefit Values shall be submitted to a title attorney with at least ten (10) years’ experience in oil and gas titles as selected by: (y) mutual agreement of Buyer and Seller; or (z) absent such agreement during the ten (10) Business Day period, by the Dallas office of the American Arbitration Association (the “Title Consultant”). The Title Consultant shall not have been employed by any party or its Affiliates within the five (5) year period preceding the arbitration. The Title Consultant, once appointed, shall have no ex parte communications with any of the parties concerning the determination required hereunder. All communications between any party or its Affiliates and the Title Consultant shall be conducted in writing, with copies sent simultaneously to the other party in the same manner, or at a meeting or conference call to which the representatives of both Seller and Buyer have been invited and of which such parties have been provided at least five (5) days’ notice. Within ten (10) days of appointment of the Title Consultant, each of Seller and Buyer shall present the Title Consultant with its claim notice or its response, as applicable, and all other supporting information that it desires, with a copy to the other party. The Title Consultant shall also be provided with a copy of this Agreement. Within forty-five (45) days after receipt of such materials and after receipt of any additional information required by the Title Consultant, the Title Consultant shall make its determination, which shall be final and binding upon all parties, without right of appeal, absent manifest error. In making his determination, the Title Consultant shall be bound by the rules set forth in this Section 5.6. In no event shall any Title Defect Value exceed the estimate given by Buyer in its claim notice delivered in accordance with Section 5.6.2(a), and in no event shall any Title Benefit Value exceed any estimate given by Seller or Buyer in a claim notice delivered in accordance with Section 5.6.2(b). The Title Consultant shall act as an expert for the limited purpose of determining: (A) the existence of any timely and properly asserted Title Defect or Title Benefit in dispute; (B) whether or to the extent to which any disputed curative action has succeeded in curing a Title Defect; and (C) specific disputed Title Defect Values or Title Benefit Values submitted by either party. The Title Consultant 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. Seller shall bear one-half (1/2) and Buyer shall bear one-half (1/2) of the costs and expenses of the Title Consultant.

5.6.3 Exclusive Remedy. Except for the Special Warranty, the remedies set forth in this Section 5.6 are Buyer’s exclusive remedies under this Agreement for all title defects (including Title Defects), and Seller shall have no other liability to Buyer with respect to title defects (including Title Defects).

5.7 Casualty Losses and Government Takings.

5.7.1 Notice of Casualty Losses and Government Takings. If, prior to the Closing Date, all or a portion of the Property is damaged or destroyed by fire, flood, storm, or other accident (“Casualty Loss”), or is taken in condemnation or under the right of eminent domain, or if proceedings for such purposes shall be pending or threatened (“Government

Taking”), Seller must promptly notify Buyer in writing of the nature and extent of the Casualty Loss or Government Taking and Seller’s estimate of the cost required to repair or replace that portion of the Property affected by the Casualty Loss or value of the Property taken by the Government Taking. Notwithstanding the foregoing, no individual matter described above shall be deemed to be or constitute a Casualty Loss unless the estimate of the cost required to repair or replace that portion of the Property affected by the Casualty Loss for such matter exceeds One Hundred Thousand Dollars ($100,000), net to Seller’s interest in the affected portion of the Property, and no Casualty Loss or Government Taking will be considered a Title Defect under Section 5.6.

5.7.2 Remedies for Casualty Losses and Government Takings. With respect to each Casualty Loss to or Government Taking of the Property, Seller and Buyer will have the following rights and remedies:

(a) Subject to Buyer’s termination right under Section 5.8, the parties will proceed with Closing and Seller shall elect either: (i) to make a downward adjustment to the Purchase Price by the lower of Seller’s estimate of the cost to repair or replace that portion of the Property affected by the Casualty Loss or the Government Taking or the Allocated Value of the Property subject to the Casualty Loss or taken in the Government Taking, or (ii) if Buyer agrees (in its sole discretion), indemnify Buyer through a document reasonably acceptable to Seller and Buyer against actual costs or expenses that Buyer reasonably incurs to repair or replace the portion of the Property affected by the Casualty Loss or the Government Taking, such amount not to exceed the Allocated Value for such Property. In the event that any Property is repaired or replaced under clause (ii) above and the repaired or replaced Property is newer than the Property that was damaged, destroyed or taken, or otherwise represents an upgrade from the Property that was damaged, destroyed or taken, Buyer shall bear the portion of the cost of repair or replacement attributable to the reduction in age or increase in quality.

(b) In addition to the remedies set forth in Section 5.7.2(a), Seller and Buyer will have the termination rights in connection with Casualty Losses and Government Takings set forth in Section 5.8.

5.7.3 Insurance Proceeds and Settlement Payments. In each case under subparts (a) and (b) of Section 5.7.2, Seller will be entitled to (a) all insurance proceeds with respect to any such Casualty Loss, (b) all sums paid to Seller or Buyer by third Persons by reason of any such Casualty Loss, and (c) all compensation paid to Seller or Buyer with respect to any such Government Taking.

5.7.4 Change in Condition. Buyer will assume all risk and loss with respect to any change in the condition of the Property from and after the Effective Time for production of Hydrocarbons through normal depletion (including the watering-out, casing collapse or sand infiltration of any Well), the depreciation of personal property through ordinary wear and tear, and changes arising from Seller’s operations conducted in accordance with Article 10. None of the events or conditions set forth in this Section 5.7.4 will be considered a Casualty Loss or Title Defect with respect to the Property, nor will they be cause for any other reduction in the Purchase Price, or give rise to any right to terminate this Agreement.

5.8 Termination Due to Impairments to the Property. If the sum of (i) all Title Defect Values for Title Defects asserted in good-faith by Buyer pursuant to Section 5.6.2(a) that remain uncured at Closing, less the sum of all Title Benefit Values, plus (ii) all Environmental Defect Values for Adverse Environmental Conditions asserted in good-faith by Buyer pursuant to Section 5.3.3, plus (iii) the Allocated Values of any Property excluded pursuant to Section 5.3.4(a)(iii) and Section 5.5 and/or pursuant to a Governmental Taking, plus (iv) the value of all Casualty Losses that occur after the Execution Date but prior to the Closing Date, exceeds twenty percent (20%) of the Purchase Price, then either Seller or Buyer may terminate this Agreement, and neither party will have any further obligation to conclude the transfer of the Property under this Agreement; provided, however, that Buyer’s indemnity obligations under Section 5.2 and Section 8.3.3 and the obligations under Section 11.3 shall survive such termination. Any party exercising a right of termination under this Section 5.8 must notify the other party in writing no later than one (1) Business Day before the Scheduled Closing Date of its election to terminate this Agreement pursuant to this Section 5.8.

5.9 Xxxx-Xxxxx-Xxxxxx Compliance. The consummation of the transaction contemplated by this Agreement is subject in all respects to and conditioned upon compliance by the parties with the Xxxx-Xxxxx-Xxxxxx Antitrust Improvements Act of 1976, as amended, and rules and regulations promulgated pursuant thereto (the “Xxxx-Xxxxx-Xxxxxx Act”), to the extent that the Xxxx-Xxxxx-Xxxxxx Act is applicable to the transaction contemplated by this Agreement. Buyer and Seller agree to (or to cause its applicable Affiliate to) make such filings with, and provide such information to, the Federal Trade Commission and the Department of Justice with respect to the transaction contemplated by this Agreement as are required in connection with the Xxxx-Xxxxx-Xxxxxx Act within ten (10) Business Days after the Execution Date.

If filing a Notification and Report Form for the transaction contemplated by this Agreement is required by the Xxxx-Xxxxx-Xxxxxx Act, Buyer and Seller each agree (i) to request (or cause its applicable Affiliate to request) early termination of the waiting period under the Xxxx-Xxxxx-Xxxxxx Act, (ii) to respond as promptly as practicable to all inquiries received from the Federal Trade Commission or the Department of Justice for additional information or documentation, (iii) to keep each other apprised of the status of matters relating to the Xxxx-Xxxxx-Xxxxxx Act, including promptly furnishing the other with copies of any material communications received from the Federal Trade Commission or Department of Justice regarding the transaction, (iv) to permit counsel for the other party a reasonable opportunity to review in advance, and consider in good faith the views of the other party in connection with, any proposed written communication to the Federal Trade Commission or Department of Justice, and (v) not to participate in any substantive meeting or discussion, either in person or by telephone, with the Federal Trade Commission or Department of Justice regarding the transaction unless it consults with the other party in advance and, to the extent not prohibited, give the other party the opportunity to attend and participate.

8.8.2 Seller shall have no liability for any Claims under Section 8.4.1 until, and only to the extent that, the aggregate amount of all such Claims actually incurred by Buyer thereunder (excluding Claims for which Section 8.8.1 applies) exceeds an amount equal to two percent (2%) of the Purchase Price (the “Deductible Amount”), in which event Seller’s indemnity obligations under Section 8.4.1 shall apply only to Claims (excluding Claims for which Section 8.8.1 applies) to the extent that they exceed the Deductible Amount (subject to the maximum liability provided for in Section 8.8.3 below); provided, however, the limitation in this Section 8.8.2 shall not apply to any Claims for breach of any Fundamental Representation.

8.8.3 In no event shall Seller’s aggregate liability for any Claims under Section 8.4.1 or Section 8.4.2 exceed ten percent (10%) of the Purchase Price (the “Cap Amount”), and Buyer waives and releases and shall have no recourse against Seller for any Claims under Section 8.4.1 or Section 8.4.2 in excess of such Cap Amount; provided, however, the limitation in this Section 8.8.3 shall not apply to (and Buyer does not waive or release) any Claims for breach of any Fundamental Representation or breach of any covenant in Article 9.

8.9 Survival. All of the covenants, agreements, representations and warranties made by the parties in this Agreement will survive the Closing, the execution and delivery of the Assignment and other instruments under this Agreement, and the transfer of the Property between the parties, and they shall not be merged into or superseded by the Assignment or other documents delivered at Closing. Notwithstanding anything herein to the contrary, Buyer will not be entitled to make a Claim against Seller: (1) in connection with any breach of or inaccuracy in any of the representations and warranties contained in Section 3.1 and Section 3.2 (other than the Fundamental Representations) unless Buyer notifies Seller of that Claim in writing pursuant to a Claim Notice within twelve (12) months after the Closing Date, (2) in connection with Seller’s failure to perform or satisfy its covenants or other agreements in this Agreement to be performed prior to Closing unless Buyer notifies Seller of that Claim in writing pursuant to a Claim Notice within twelve (12) months after the Closing Date; (3) in connection with Seller’s failure to perform or satisfy its covenants or other agreements in this Agreement to be performed on or after Closing (other than any covenant in Section 8.4.4 or Article 9) unless Buyer notifies Seller

of that Claim in writing pursuant to a Claim Notice within thirty-six (36) months after the Closing Date or (4) in connection with Seller’s failure to perform or satisfy its covenants or other agreements in Section 8.4.4 or Article 9 unless Buyer notifies Seller of that Claim in writing pursuant to a Claim Notice within thirty (30) days following the expiration of the applicable statute of limitations.

8.10 Exclusive Remedy. If Closing occurs, absent actual fraud, the right of indemnification set forth in Section 5.2, Section 5.3.4, Section 5.5.2(c), this Article 8 and Section 11.1 shall be the sole and exclusive remedy of the parties to this Agreement and all indemnified parties for the breach of any representation or warranty or any covenant or agreement set forth in this Agreement, and each party hereto covenants and agrees not to seek or assert any other remedy with respect thereto following Closing; provided, however, that the foregoing shall not limit the right of any party hereto to seek any equitable remedy available to enforce the rights of such party under this Agreement.

8.11 Treatment of Indemnity Payments. Any payment pursuant to this Article 8 shall be treated for Tax purposes as an adjustment to the Purchase Price except to the extent otherwise required by applicable law.

ARTICLE 9

TAXES AND EXPENSES

9.1 Recording Expenses. Buyer shall pay all costs of recording and filing the Assignment for the Property, all other state and federal transfer documents, and all other instruments that must be filed to effectuate the transfer of the Property.

9.2 Asset Taxes.

9.2.1 Seller shall retain responsibility for, and shall bear and pay, all ad valorem, property, excise, sales, use severance, production or similar Taxes (including any interest, fine, penalty or additions to Tax imposed by a governmental authority in connection with such Taxes) based upon operation or ownership of the Properties or the production of Hydrocarbons therefrom (“Asset Taxes”) for (i) any period ending prior to the Effective Time, and (ii) the portion of any Tax period beginning before and ending after the Effective Time (a “Straddle Period”) ending immediately prior to the Effective Time. All Asset Taxes with respect to the ownership or operation of the Properties 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 2.2, payments will be made to cause the appropriate party to bear the Asset Taxes allocable to such Person under this Section 9.2.1. 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.

9.2.2 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 2.2 or Section 2.3, 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 2.3, 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 9.2.1.

9.2.3 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 9.2.1. 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 9.2.1. Buyer shall file any Post-Closing Tax Return relating to a Straddle Period in a manner consistent with past practice. Within fifteen (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).

9.3 Cooperation. At the expense of the requesting party, Buyer and Seller agree to furnish or cause to be furnished to the other, upon request, as promptly as practicable, such information and assistance relating to the Properties, including, without limitation, access to books and records and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, as is reasonably necessary for the filing of all Tax Returns by Buyer or Seller, the making of any election relating to Taxes, the preparation for any audit by any Taxing authority and the prosecution or defense of any claim, suit or proceeding relating to any Tax. Each of Buyer and Seller shall retain all books and records with respect to Taxes pertaining to the Properties for a period of at least seven (7) years following the Closing Date.

9.4 Notice. Seller shall promptly notify Buyer in writing upon receipt by Seller of notice of any pending or threatened Tax audits or assessments relating to the income, properties or operations of Seller that reasonably may be expected to relate to or give rise to a lien, encumbrance or other charge on the Property. Each of Buyer and Seller shall promptly notify the other in writing upon receipt of notice of any pending or threatened Tax audit or assessment challenging the Allocation.

9.5 Transfer Taxes. All transfer, stamp, documentary, sales, use, registration, value-added and other similar Taxes (including all applicable real estate transfer Taxes) incurred in connection with this Agreement and the transactions contemplated hereby (“Transfer Taxes”) will be borne by Buyer.

9.6 Income Taxes. Each party shall be responsible for its own state and federal income taxes, if any, as may result from this transaction.

9.7 Incidental Expenses. Each party shall bear its own respective expenses incurred in connection with the negotiation and Closing of this transaction, including its own consultants’ fees, attorneys’ fees, accountants’ fees, and other similar costs and expenses.

Further, during the Specified Period, Seller shall not, and shall not authorize or permit any of its Affiliates or any of their respective officers, directors, employees,

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

1. Subscription.

a. Subject to the terms and conditions hereof, Subscriber hereby agrees to subscribe for and purchase, and the Company hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, the Acquired Shares (such subscription and issuance, the “Subscription”).

b. On or prior to the date on which any Other Subscription Agreement, if any, is entered into, after consultation with the Company, Subscriber shall notify the Company of the number of Additional Acquired Shares constituting “Acquired Shares” hereunder that Subscriber shall elect and be obligated to purchase on the Closing Date as provided herein, which notice shall include the allocation of Class A Acquired Shares and Series B Acquired Shares constituting the “Acquired Shares” (including the Additional Acquired Shares) to be purchased hereunder (the “Total Acquired Shares”); provided that the maximum number of Class A Acquired Shares to be purchased hereunder (the “Maximum Share Number”), together with any additional shares of Class A Common Stock to be issued by the Company pursuant to all Other Subscription Agreements, if any, in the aggregate, does not exceed 19.9% of the Company’s outstanding shares of Class A Common Stock and Class C Common Stock (as defined below), on a combined basis, on the date hereof, and, to the extent the Maximum Share Number would be exceeded by issuing all Acquired Shares as shares of Class A Common Stock, Subscriber shall instead be obligated to purchase, and the Company shall be obligated to issue to Subscriber, that number of Series B Acquired Shares that, together with the number of Class A Acquired Shares to be purchased hereunder, equals the number of Total Acquired Shares to be purchased hereunder. At such time, Subscriber and the Company shall update and amend Subscriber’s signature page hereto to reflect the number of Acquired Shares to be purchased, and the aggregate Purchase Price to be paid, on the Closing Date as provided herein.

c. Notwithstanding anything to the contrary set forth herein, if the Company determines to finance any portion of the Remaining Purchase Price by issuing additional shares of its common stock or preferred stock to one or more additional purchasers (the “Other Purchasers”) pursuant to any Other Subscription Agreement or otherwise at a price per share less than the Purchase Price payable by Subscriber hereunder, then Subscriber’s Purchase Price shall be reduced to equal the lowest per share purchase price to be paid by any such Other Purchaser (including on an as-converted basis for any shares of Series B Preferred Stock).

2. Closing.

a. The closing of the Subscription contemplated hereby (the “Closing”) is contingent upon the substantially concurrent consummation of the Transaction and shall occur immediately prior thereto. The Closing and the closing of the Transaction shall occur on December 30, 2016, subject to extension upon five (5) business days’ prior written notice to Subscriber (such date, including as so extended, the “Closing Date”). At least three (3) business days prior to the Closing Date, Subscriber shall deliver to the Company, to be held in escrow until the Closing, the Purchase Price for the Acquired Shares by wire transfer of U.S. dollars in immediately available funds to the account specified by the Company in Annex B hereto. Immediately prior to the closing of the Transaction on the Closing Date, (a) the Purchase Price shall be released from escrow automatically and without further action by the Company or Subscriber, and (b) upon such release, the Company shall deliver to Subscriber (i) the Acquired Shares in book entry form, free and clear of any liens or other restrictions whatsoever (other than those arising under state or federal securities laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions) or to a custodian designated by Subscriber, as applicable, and (ii) written notice from the Company or its transfer agent evidencing the issuance to Subscriber of the Acquired Shares on and as of the Closing Date. In the event the Closing does not occur on the Closing Date, the Company shall promptly (but not later than one (1) business day thereafter) return the Purchase Price to Subscriber.

b. The Closing shall be subject to the conditions that, on the Closing Date:

(i) no suspension of the qualification of the Acquired Shares for offering or sale or trading in any jurisdiction, or initiation or threatening of any proceedings for any of such purposes, shall have occurred;

(ii) all representations and warranties of the Company and Subscriber contained in this Subscription Agreement shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Material Adverse Effect (as defined herein), which representations and warranties shall be true in all respects) at and as of the Closing Date, and consummation of the Closing shall constitute a reaffirmation by each of the Company and Subscriber of each of the representations, warranties and agreements of each such party contained in this Subscription Agreement as of the Closing Date, but in each case without giving effect to consummation of the Transaction;

(iii) the Company shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing;

(vii) the Company shall have received proceeds from debt or equity financings on terms satisfactory to the Company that, together with the proceeds from the sale of the Acquired Shares hereunder, will be sufficient for the Company to pay the purchase price for the Transaction pursuant to the Purchase Agreement and the Assignment on the Closing Date;

(viii) the Transaction shall be consummated substantially concurrently with the Closing in accordance with the terms of the Purchase Agreement.

c. At the Closing, the parties hereto shall execute and deliver such additional documents and take such additional actions as the parties reasonably may deem to be practical and necessary in order to consummate the Subscription as contemplated by this Subscription Agreement.

b. The Company shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless Subscriber (to the extent a seller under the Registration Statement), the officers, directors, agents, partners, members, managers, stockholders, affiliates, employees and investment advisers of each of them, each person who controls Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, managers, stockholders, agents, affiliates, employees and investment advisers of each such controlling person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and investigation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, or (ii) any violation or alleged violation by the Company of the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 5, except to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information regarding Subscriber furnished in writing to the Company by Subscriber expressly for use therein. The Company shall notify Subscriber promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 5 of which the Company is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Class A Acquired Shares by Subscriber.

c. Subscriber shall, severally and not jointly with any other subscriber, indemnify and hold harmless the Company, its directors, officers, agents and employees, each person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statements or omissions are based solely upon information regarding Subscriber furnished in writing to the Company by Subscriber expressly for use therein. In no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Class A Acquired Shares giving rise to such indemnification obligation.

d. Prior to the Special Meeting, Subscriber shall not sell, contract to sell, pledge or otherwise dispose of any Series B Acquired Shares without the prior written consent of the Company, other than to affiliates of Subscriber.

ANNEX A

Terms of Series B Preferred Stock

Defined terms used in this Annex A shall have the meanings ascribed thereto in the Subscription Agreement to which this Annex A is annexed.

Issuer	Centennial Resource Development, Inc., a Delaware corporation.

Securities Offered	Shares of Series B Preferred Stock (including any Additional Acquired Shares that are shares of Series B Preferred Stock) up to the maximum number of Series B Acquired Shares subject to the Subscription Agreement, with a liquidation preference of $0.0001 per share (the “Liquidation Preference”).

Liquidation Preference	In the event of a voluntary or involuntary liquidation, dissolution or winding up of the Company (each a “Liquidation Event”), holders of the Series B Preferred Stock will first be entitled to receive the Liquidation Preference per share, to the date of payment before any distribution of assets is made to holders of the Class A Common Stock or any other equity securities of the Company that by their terms rank junior to the Series B Preferred Stock as to liquidation rights. If, in the event of a Liquidation Event, after payment of any amounts to be paid in respect of any of the Company’s equity securities that rank senior to the Series B Preferred Stock as to the payment of dividends or the distribution of assets upon the liquidation, dissolution or winding up of the Company (“Senior Securities”), the Company’s assets available for distribution are insufficient to fully pay the liquidation payments owing to the holders of the Series B Preferred Stock and the holders of any of the Company’s equity securities that rank on par with the Series B Preferred Stock as to the payment of dividends or the distribution of assets upon the liquidation, dissolution or winding up of the Company (“Parity Securities”), the holders of the Series B Preferred Stock and such Parity Securities will share ratably in the distribution of the Company’s assets in proportion to the full liquidating distributions to which they would otherwise have been respectively entitled. After the payment of the Liquidation Preference to the holders of the Series B Preferred Stock (and payment of any amount to be paid in respect of any Senior Securities and any Parity Securities), the remaining assets of the Company shall be distributed ratably to the holders of the

	Company’s common stock and the Series B Preferred Stock on a common equivalent basis (and any other participating equity securities of the Company).

	For all purposes hereunder, the following events shall not constitute a Liquidation Event (i) the merger or consolidation of the Company with any other entity, including a merger or consolidation in which the holders of the Series B Preferred Stock receive cash, securities or property for their shares, the sale, lease or exchange of all or substantially all of the Company’s assets for cash, securities or other property, (ii) the conversion of the Company into another legal entity, or (iii) sale of all or substantially all of the assets of the Company to an affiliate of the Company in connection with a reorganization or liquidation.

Conversion	Each share of Series B Preferred Stock shall automatically convert into 250 shares of Class A Common Stock, subject to adjustments for stock splits, stock dividends, reorganization, recapitalizations and the like, upon the receipt by the Company of the Stockholder Approval.

Voting Rights	The holders of the Series B Preferred Stock shall have no voting rights, except as set forth below or as required by law. The affirmative vote of holders of a majority of the Series B Preferred Stock then outstanding, voting as a separate class, is required to (a) approve any amendment, alteration or repeal of any provision of the Certificate of Designation relating to the Series B Preferred Stock or the Company’s charter that adversely affects the rights, preferences, privileges or voting powers of the Series B Preferred Stock or (b) authorize the issuance of any Senior Securities or Parity Securities. With respect to any matter on which the holders of Series B Preferred Stock are entitled to vote, each share of Series B Preferred Stock will be entitled to one vote on such matter.

Dividends	No dividends shall be payable on the Series B Preferred Stock; provided, that holders of the Series B Preferred Stock shall be entitled to pro rata participation in any dividends paid on the Company’s common stock, on a common equivalent basis.

No Maturity Date	The Series B Preferred Stock is perpetual unless, as described below, redeemed by the Company at its option.

Redemption at the Company’s Option	Beginning on the third anniversary of the Closing Date, the Company will have the right, but not the obligation, to redeem all (but not less than all) of each holder’s shares of Series B Preferred Stock for a redemption price per share, determined on an as converted basis, equal to the average of

Annex A-2

	the last reported sale price for a share of Class A Common Stock on NASDAQ for each of the last 10 consecutive trading days prior to the redemption date or, if such shares are no longer traded, at the fair market value of the Class A Common Stock, as determined in good faith by the Board of Directors of the Company.

Use of Proceeds	Proceeds of the offering will be used to pay a portion of the purchase price for the Transaction
