Sellers shall at Purchaser’s request make reasonable documentation available to support the Preliminary Section 2.2(b) Schedule.

(c) As soon as reasonably practicable, but not later than forty-five (45) days following receipt of the Preliminary Section 2.2(b) Schedule, Purchaser shall deliver to Sellers a written report containing any changes that Purchaser proposes to be made in such schedule (and specifying the reasons therefor in reasonable detail). The Parties shall undertake to agree on a final schedule no later than fifteen (15) Business Days subsequent to the receipt by Sellers of Purchaser’s proposed changes (such final schedule, if any, the “Final Section 2.2(b) Schedule”).

Section 2.4 Closing Cash Payment and Post-Closing Purchase Price Adjustments.

(a) Not later than five (5) Business Days prior to the Closing Date, Sellers shall prepare and deliver to Purchaser a settlement statement (the “Closing Settlement Statement”) calculating the amount equal to the Cash Purchase Price as adjusted to give effect to Sellers’ good faith estimate of the adjustments provided for in Section 2.3 based upon the best information available to Sellers (or, if then determinable, the final amounts thereof), together with reasonable documentation in support of such calculation. Purchaser shall have two (2) Business Days to review the settlement statement. On the day following expiration of such two (2) Business Day review period, Purchaser shall submit a written report containing any changes Purchaser proposes to be made to the settlement statement. Sellers and Purchaser shall agree on a final settlement statement no later than one (1) Business Day prior to Closing; provided, however, if Sellers and Purchaser are unable to agree, then, subject to Section 2.4(b), Sellers’ good faith determination shall be used for purposes of the Closing Cash Payment to be made at the Closing. The calculation delivered by Sellers in accordance with this Section 2.4(a), as adjusted in accordance with the immediately preceding sentence, if applicable, shall constitute the dollar amount to be paid by Purchaser to Sellers at the Closing (the “Closing Cash Payment”).

(b) Within five (5) days following the expiration of the Cure Period, Sellers shall prepare and deliver to Purchaser a draft statement (the “Post-Closing Statement”) setting forth the final calculation of the Cash Purchase Price taking into account any adjustments pursuant to Section 2.3 (including the calculation of the Effective Time Net Working Capital and any adjustments pursuant to Article 6), together with reasonable documentation in support of such calculation. As soon as reasonably practicable but not later than the thirtieth (30th) day following receipt of Sellers’ statement hereunder, Purchaser shall deliver to Sellers a written report (an “Adjustment Notice”) containing any changes Purchaser proposes be made in such statement. Purchaser shall be deemed to have accepted and agreed to all items in the Post-Closing Statement other than such matters that are proposed to be changed in the Adjustment Notice.

(i) mutually agreed upon by Sellers and Purchaser during such thirty (30) day period, the final Cash Purchase Price shall be conclusive and binding on the Parties.

(ii) not mutually agreed upon by Sellers and Purchaser during such thirty (30) day period, then Sellers or Purchaser may require for Deloitte & Touche LLP (the “Dispute Auditor”) to resolve any disagreements. Should Deloitte & Touche LLP fail or refuse to agree to serve as Dispute Auditor within ten (10) days after written request from any Party to serve, and the Parties fail to agree in writing on a replacement Dispute Auditor within five (5) days after the end of that ten (10) day period, or should no replacement Dispute Auditor agree to serve within fifteen (15) days after the original written request pursuant to this sentence, the Dispute Auditor shall be appointed by the Houston, Texas office of the American Arbitration Association. In connection with the engagement of the Dispute Auditor, each of Sellers and Purchaser shall execute such engagement, indemnity and other agreements as the Dispute Auditor shall require as a condition to such engagement. The Dispute Auditor shall determine as promptly as practicable, but in any event within thirty (30) days after the selection of the Dispute Auditor, based solely on written submissions provided by Purchaser and Sellers to the Dispute Auditor (and without independent investigation on the part of the Dispute Auditor) within ten (10) days following the Dispute Auditor’s selection, whether and to what extent (if any) Sellers’ statement requires adjustment. In resolving any disputed item, the Dispute Auditor shall act as an expert and not an arbitrator, and shall resolve only the items set forth in the Adjustment Notice that are still in dispute and may not assign a value to any item greater than the highest value for such item claimed by either Sellers or Purchaser or less than the lowest value for such item claimed by either Sellers or Purchaser. The costs of the Dispute Auditor shall be borne pro rata between Sellers and Purchaser with each of Sellers and Purchaser being responsible for such Dispute Auditor’s costs to the extent the Dispute Auditor has not selected such Party’s position on an aggregate dollar basis with respect to all amounts submitted for resolution by the Dispute Auditor. The determination of the Dispute Auditor shall be final, conclusive and binding on Purchaser and Sellers. The date on which the final Cash Purchase Price is finally determined in accordance with this Section 2.4(b) is referred to as the “Determination Date.”

Any difference in the Closing Cash Payment and the final Cash Purchase Price shall be paid by the owing Party to the owed Party within ten (10) Business Days of the Determination Date. Any post-Closing payment pursuant to this Section 2.4 shall bear interest from the Closing Date to the date of payment at the Agreed Rate.

24

(c) Purchaser shall assist Sellers in preparation of the Post-Closing Statement of the Cash Purchase Price under Section 2.4(b) by furnishing invoices, receipts, reasonable access to personnel and such other assistance as may be requested by Sellers to facilitate such process post-Closing.

The Parties understand that none of the bonds, letters of credit and guarantees, if any, posted by Sellers or any other Affiliate of the Company (including the Company Parties to the extent Sellers or their Affiliates (except the Company Parties) provide credit support for any such bonds, letters of credit or guarantees) with any Governmental Authority or third Person and relating to the E&P Business are to be transferred to Purchaser. On or before the Closing, Purchaser shall obtain, or cause to be obtained in the name of Purchaser, replacements for the bonds, letters of credit and guarantees identified in Schedule 5.11 and such other bonds, letters of credit and guarantees posted (or supported) by Sellers or such Affiliates, that may first arise between the Execution Date and Closing in the ordinary course of business that are disclosed by Sellers to Purchaser at least five (5) Business Days prior to the Closing Date (“New Bonds and LCs”), and shall use commercially reasonable efforts to cause, effective as of the Closing, the cancellation or return to Sellers of such bonds, letters of credit and guarantees posted (or supported) by Sellers or such Affiliates, and Sellers shall provide reasonable cooperation to Purchaser in connection therewith. Purchaser may also provide evidence that such replacements are not necessary as a result of existing bonds, letters of credit or guarantees that Purchaser has previously posted as long as such existing bonds, letters of credit or guarantees are adequate to secure the release of those posted (or supported) by Sellers. Schedule 5.11 identifies the bonds, letters of credit and guarantees posted (or supported) by Sellers or any other Affiliate of the Company (including the Company Parties to the extent Sellers or their Affiliates (except the Company Parties) provide credit support for any such bonds, letters of credit or guarantees) with respect to the E&P Business as of the Execution Date, which Sellers may update through the Closing Date to reflect New Bonds and LCs.

52

Section 5.12 Certain Affiliate Agreements. At or prior to the Closing, the applicable Seller (or Affiliate of such Seller) or EnCap Affiliate, on the one hand, and the applicable Company Party, on the other hand, shall terminate all intercompany agreements, contracts, loans, payables, receivables, arrangements and any other transactions between a Company Party, on the one hand, and Seller or any of its Affiliates or an EnCap Affiliate, on the other hand (the “Terminating Agreements”), including the intercompany arrangements in Schedule 5.12(a) but excluding those intercompany arrangements in Schedule 5.12(b).

Section 5.13 Preference Rights; Consents.

(a) Promptly after the Execution Date, the Company shall prepare and send (i) notices to the holders of any consents to assignment or change of control of any Company Party that are set forth in Schedule 3.11 or that are discovered after the Execution Date (and which are triggered by the transactions contemplated hereby) requesting consents to the transactions contemplated by this Agreement and (ii) notices to the holders of any applicable preferential rights to purchase, rights of first negotiation or similar rights that are set forth in Schedule 3.11 or that are discovered after the Execution Date (and which are triggered by the transactions contemplated hereby) in compliance with the terms of such rights and requesting waivers of such rights. Prior to Closing, the Company Parties shall reasonably cooperate with Purchaser to cause such consents to assignment or change of control and waivers of preferential rights to purchase or similar rights (or the exercise thereof) to be obtained and delivered prior to Closing, provided, however, that neither Sellers, the Company Parties nor any of their Affiliates shall be required to make payments or undertake obligations to or for the benefit of the holders of such rights in order to obtain the consents and waivers. In the event any consent is not obtained prior to Closing (or any fee payable has not been paid in connection therewith), Sellers shall not be obligated to take any action that would result in a breach of any Company Contract or Company Earned Lease for which the consent has not been obtained (or any fee payable has not been paid in connection therewith) and Sellers and Purchaser will have the right to take such actions as are reasonably necessary to comply with the applicable Company Contract or Company Earned Lease. Following Closing, Sellers and Purchaser shall cooperate in good faith to obtain any such consents (and paying any fees required in connection therewith) and waivers.

(b) Should the holder of the preferential purchase right validly exercise the same (whether before or after Closing), then:

(i) the Company Party owning the applicable asset of the E&P Business shall transfer such asset to the holder of the preferential purchase right on the terms and provisions set out in the applicable preferential purchase right provision; and

(ii) such Company Party shall be entitled to the consideration paid by such holder.

53

Section 5.14 Directors’ and Officers’ Indemnification and Insurance.

(a) After Closing, the Organizational Documents of the Company Parties shall contain provisions no less favorable with respect to indemnification than are set forth in their respective Organizational Documents immediately prior to Closing and set forth in any indemnification agreement currently in effect between any Seller or any Company Party and any current or former officer or director of any Company Party, which provisions shall not be amended, repealed or otherwise modified for a period of six (6) years from the Closing Date in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Closing Date, were directors, officers, fiduciaries or agents of any Company Party; provided, that, in the event that any claim for indemnification is asserted or made within such six (6) year period, all rights to indemnification in respect of such claim shall continue until the final disposition of such claim.

(b) After Closing, Purchaser shall, in the same manner as provided by the Company Parties immediately prior to the Execution Date, indemnify and hold harmless, each present and former director and officer of the Company Parties (collectively, the “D&O Indemnified Parties”) against all Liabilities (including reasonable attorneys’ fees) paid or incurred in connection with any claim, action, suit, proceeding or investigation (whether arising before or after the Closing Date), whether civil, criminal, administrative or investigative, arising out of or pertaining to any action or omission occurring on or before the Closing Date in their capacity as an officer, director, employee, fiduciary or agent of the Company Parties.

(c) This Section 5.14 is intended to be for the benefit of, and shall be enforceable by, present or former directors and officers of each Company Party, their respective heirs and personal representatives and shall be binding on Purchaser and its successors and assigns. In the event that Purchaser or any of its successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any Person (including by dissolution), then, and in each such case, Purchaser shall cause proper provision to be made so that the successors and assigns of Purchaser assume and honor the obligations set forth in this Section 5.14. The agreements and covenants contained herein shall not be deemed to be exclusive of any other rights to which any such present or former director or officer is entitled, whether pursuant to Law, contract or otherwise. Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to any Company Party or their respective officers and directors and Business Employees, it being understood and agreed that the indemnification provided for in this Section 5.14 is not prior to or in substitution for any such claims under any such policies.

Section 5.15 Additional Acreage.

(a) (i) The Company Parties, at their sole option, may, from the Execution Date until Closing, enter into agreements to acquire and/or acquire additional oil, gas and other leasehold interests covering all the Target Depths in the area covered by the lands described on Schedule 5.15(a) attached hereto, including additional undivided interests in the Leases and (ii) following Closing, the Company Parties shall acquire those additional oil, gas and other leasehold interests covering all the Target Depths

54

(excluding the Company Unearned Leases) which the Company Parties have entered into definitive agreements to acquire as of the Closing Date but, as of the Closing Date, have not received assignments of or otherwise consummated the transactions related thereto (collectively, the “New Interests”), such New Interests not to exceed two thousand five hundred (2,500) Net Mineral Acres in the aggregate, the Company Parties’ title to each such New Interest shall not be subject to Lease Burdens greater than twenty-five percent (25%) and the acquisition price for each such New Interest shall not exceed Ten Thousand Dollars ($10,000) per Net Mineral Acre covered by such New Interest.

(b) Premium for Acquisition of New Interests.

(i) For each New Interest (other than the New Interests described in Section 5.15(b)(ii)), Purchaser shall pay (as an upward adjustment to the Cash Purchase Price) an amount equal to (A) the out-of-pocket acquisition price paid by the Company Parties for such New Interest plus (B) a premium equal to the amount set forth in column “(i)” of Schedule 5.15(b).

(ii) For those New Interests which, in aggregate, result in one of the Company Parties becoming the Operator of a governmental section (where the Company Parties previously were not Operator), Purchaser shall pay (as an upward adjustment to the Cash Purchase Price) an amount equal to (A) the out-of-pocket acquisition price paid by the Company Parties for such New Interests plus (B) a premium equal to the amount set forth in column “(ii)” of Schedule 5.15(b).

(c) Other than the acquisition of the New Interests, any acquisition of any additional right, title and interest in and to the Leases or additional oil, gas and other mineral interests by any Company Party shall require the prior written consent of Purchaser, which may be withheld in Purchaser’s sole discretion. “Operator” shall mean (i) the operator as to all the Target Depths under the applicable joint operating agreement or similar agreement or forced pooling order or (ii) in the event no joint operating agreement or similar agreement or forced pooling order covers such New Interest, then the majority interest owner as to all the Target Depths in the applicable governmental section.

(d) Notwithstanding the foregoing, Sellers shall have the right to utilize New Interests as Replacement Acreage or Replacement Interests, if the applicable requirements are met, in lieu of receiving payment therefor as provided in Section 5.15(b) by providing written notice to Purchaser prior to the expiration of the Cure Period.

Section 5.16 Employee and Benefit Plan Matters.

(a) On or before the Closing Date, the Company Parties shall take all necessary actions to transfer (i) the employment of each Business Employee, and (ii) the engagement of each Business Contractor, other than those contractors whose services are terminated by the Company Parties prior to the Closing Date, to a Seller or an Affiliate of a Seller (other than any Company Party).

55

(b) Unless otherwise directed by Purchaser, prior to the Closing Date, the Company Parties shall take all actions necessary to (i) with respect to each Employee Plan sponsored or maintained by any Company Party immediately prior to the Closing Date, terminate such Employee Plan or transfer the sponsorship of such Employee Plan to a Seller or an Affiliate of Sellers (other than any Company Party); and (ii) cause each Company Party to cease to be an adopting or participating employer under any Employee Plan.

Section 5.17 Confidentiality. For a period of two (2) years following the Closing Date, Sellers shall not, and shall cause their controlled Affiliates and shall direct their Affiliates and the EnCap Affiliates, and any officers, directors, employees and representatives of Sellers, such Affiliates or such EnCap Affiliates not to, disclose to any Person any confidential information regarding the E&P Business, including information relating to pricing, technologies, trade secrets, processes, financial data, statistics or research, and development, but not including information that is or becomes generally available to the public other than as a result of disclosure by Sellers, any of their Affiliates or any EnCap Affiliates or any representative of Sellers, such Affiliates or such EnCap Affiliates; provided, that Sellers, their Affiliates and the EnCap Affiliates may disclose information that Sellers, any of their Affiliates or any EnCap Affiliates are required to disclose by applicable Law (including securities Laws) or legal process; provided, however, the foregoing shall in no way restrict the rights of Sooner Trend Minerals pursuant to the Well Data Sharing Agreement.

Section 5.18 Casualty and Condemnation. If, after the Execution Date but prior to the Closing Date, any portion of the assets of the E&P Business is destroyed or damaged by fire or other casualty or is expropriated or taken in condemnation or under right of eminent domain, Purchaser shall nevertheless be required to comply with the covenants in Article 8 and proceed to the Closing. In the event of any such casualty or taking, (i) the applicable Seller shall cause to be transferred to the applicable Company Party all sums paid to such Seller or its Affiliates (other than the Company Parties) by third Persons by reason of the casualty or taking of such assets of the E&P Business, including any sums paid pursuant to any policy or agreement of insurance or indemnity, and shall assign, transfer and set over unto such Company Party all of the rights, title and interest of such Seller or its Affiliates (other than the Company Parties) in and to any claims, causes of action, unpaid proceeds or other payments from third Persons, including any policy or agreement of insurance or indemnity, arising out of such casualty or taking, and (ii) Sellers shall, or shall cause the Company Parties to, promptly repair or replace any Company Properties damaged or lost on account thereof.

Section 5.19 Suspended Funds. At the Closing Date, Sellers shall deliver, and/or shall cause to be delivered, to Purchaser an “Excel” spreadsheet containing the owner name, owner number, social security or federal ID number, reason for suspense, and the amount of Suspended Funds payable for each entry as of the Closing Date, together with monthly line item production detail including gross and net volumes and deductions for all suspense entries and all other supporting documentation reasonably necessary for Purchaser to verify the existence of the amount of such Suspended Funds.

56

Section 5.20 Updated Schedules. Any Schedule may, from time to time, no later than three (3) Business Days prior to the Closing Date, be supplemented or amended with respect to any event, condition, fact or circumstance that first arises after the Execution Date, that would cause or constitute an inaccuracy in, or breach of, any representation or warranty in this Agreement to which such Schedule relates. The Person supplementing or amending its Schedules (the “Disclosing Party”) shall deliver a copy of the amendment or supplement, which shall clearly identify and highlight the relevant changes to such Schedules (the “Supplemental Disclosure”) to Sellers, if Purchaser is the Disclosing Party, or to Purchaser, if Sellers are the Disclosing Party (in each case, the “Receiving Party”). The Receiving Party shall have three (3) Business Days after receipt of such Supplemental Disclosure (the “Termination Period”) in which to review the Supplemental Disclosure. If a Supplemental Disclosure discloses facts that would constitute a breach of the Disclosing Party’s representations and warranties hereunder and such breach would reasonably be expected to result in the failure of the condition to Closing specified in Section 7.2(a), if Sellers are the Disclosing Party, or Section 7.1(a), if Purchaser is the Disclosing Party, to be satisfied at the Closing, then Purchaser, if Sellers are the Disclosing Party, or Sellers, if Purchaser is the Disclosing Party, may terminate this Agreement by delivering a written notice of termination to the other prior to the expiration of the Termination Period (which termination notice shall specify the representation or warranty breached, identify the specific facts in the Supplemental Disclosure that constitute the breach and describe why the failure of the condition to Closing would reasonably be expected to occur). If a notice of termination is not received with respect to any Supplemental Disclosure within the Termination Period, the Receiving Party will be deemed to have waived its right to terminate with respect to such Supplemental Disclosure and the relevant Schedule will be deemed, solely for the purpose of the Receiving Party’s condition to Closing as set forth in Section 7.1(a) or Section 7.2(a), as applicable, and not for any other purpose under this Agreement (including the indemnification provisions in Article 11), to be amended and supplemented as described in the Supplemental Disclosure as of the date hereof. For the avoidance of doubt, no Supplemental Disclosure shall be deemed to have cured any inaccuracy in or the breach of any representation or warranty contained in this Agreement for the purposes of indemnification rights in Article 11.

Section 5.21 Ultimate Parent Shares. Prior to the Closing, the Ultimate Parent will use its commercially reasonably efforts to obtain approval for listing, subject to notice of issuance, of the Ultimate Parent Shares on the New York Stock Exchange; provided it shall be approved for listing no later than the date the Ultimate Parent Shares are registered with the Securities Exchange Commission.

Section 5.22 Revised Assignment. Prior to the Closing, Sellers shall cause (i) the Company, Felix Energy and Sooner Trend Minerals to enter into the Revised Assignment and (ii) the Revised Assignment to be filed of record in each of Blaine County, Canadian County and Kingfisher County, Oklahoma. The Revised Assignment shall meet the following requirements:

(a) The body of the Revised Assignment shall be in the form attached hereto as Exhibit G;

57

(b) Exhibit A and Exhibit B of the Revised Assignment shall be completed by the Company and Sooner Trend Minerals after the Execution Date and such exhibits shall be revised (if necessary) in a manner not to convey, assign or otherwise transfer any overriding royalty interests in any Lease or Company Well, with respect to the Target Depths, to the Company and Sooner Trend Minerals, taking into account the overriding royalty interests granted pursuant to the Prior Assignment and the ORRI Assignments (as defined in the Prior Assignment), if any such conveyance, assignment or transfer would result in a Title Defect;

(c) With respect to depths other than the Target Depths (“Non-Target Depths”), Exhibit A and Exhibit B of the Revised Assignment shall be completed by the Company and Sooner Trend Minerals after the Execution Date and such exhibits shall be revised (if necessary) in a manner so that, after giving effect to the Revised Assignment, to the extent possible, Felix Energy shall own a Net Revenue Interest of seventy-five percent (75%) in the Non-Target Depths covered by the Leases to the extent covering lands included within each governmental section, as determined on a weighted average basis with respect to each such governmental section (the “Weighted NRI”), with the same being calculated (x) by multiplying, with respect to each Lease, (i) the number of Net Mineral Acres in such governmental section owned by Felix Energy in the Non-Target Depths pursuant to such Lease by (ii) the applicable Net Revenue Interest of Felix Energy in the Non-Target Depths with respect to the lands in such governmental section under such Lease, (y) adding the results of (x) together for each Lease to the extent it covers lands located within such governmental section, and then (z) dividing the total determined by (y) by the aggregate Net Mineral Acres owned by Felix Energy in the Non Target Depths with respect to the lands located within such governmental section pursuant to the Leases. For the avoidance of doubt, the Revised Assignment will not convey an overriding royalty interest on a weighted average basis, but rather will convey a separate and distinct overriding royalty interest in each Lease so as to achieve the intent of this Section 5.22(c) to the extent possible.

ARTICLE 6

EXAMINATION OF TITLE AND PROPERTIES

Section 6.1 Access.

(a) From and after the Execution Date until Closing, Sellers shall give Purchaser (and any of its officers, employees, agents, accountants, attorneys, investment bankers, landmen, consultants or other designated representatives (collectively, “Purchaser’s Representatives”)) reasonable access to the Company Properties (including the Company Records), solely for the purpose of Purchaser’s due diligence investigation of the Company Properties, but only to the extent that Company Parties may do so without violating any confidentiality or other obligations to any third Person and only to the extent that Company Parties have the authority to grant such access without breaching any obligation or restriction binding on the Company Parties (or any of their Affiliates). Such access by Purchaser shall be limited to the Company Parties’ normal business hours, and Purchaser’s investigation shall be conducted in a manner that minimizes interference with the operation of the Company Properties and at the sole cost and expense of Purchaser.

58

(b) Purchaser acknowledges that the permission of the operator (if other than the Company Parties) or another third Person may be required before Purchaser will be able to inspect portions of the Company Properties and that such permission must be obtained prior to the inspection of such portions. Sellers shall use commercially reasonable efforts to obtain such permission for Purchaser upon Purchaser’s request. All inspections pursuant to this Section 6.1 shall be conducted at Purchaser’s sole cost, risk and expense (except to the extent caused by the gross negligence or willful misconduct of any of Sellers or the Company Parties or their respective employees, agents and representatives), and any conclusions made from any such investigation done by Purchaser or any of Purchaser’s Representatives shall result from Purchaser’s own independent review and judgment. Purchaser agrees to comply with (and to cause Purchaser’s Representatives to comply with) the rules, regulations and instructions issued by the Company Parties or any operator of the Company Properties regarding the actions of Purchaser (and Purchaser’s Representatives) in conducting any inspection pursuant to this Section 6.1.

(c) All information obtained by Purchaser and its representatives under this Section 6.1 and Section 6.2 below shall be subject to the terms of that certain Confidentiality Agreement between Felix Energy and Ultimate Parent, dated as of October 23, 2015 (the “Confidentiality Agreement”), and any applicable privacy Laws regarding personal information.

Section 6.2 Environmental Property Inspection.

(a) From and after the Execution Date, until the Environmental Defect Deadline, the Company Parties shall permit Purchaser and Purchaser’s Representatives, at Purchaser’s sole risk, cost and expense, reasonable access to the Company Properties, including, subject to the terms of Section 6.1(b) above, any non-operated properties, to conduct field inspections for purposes of Purchaser’s due diligence investigation of environmental matters relating to the Company Properties (“Purchaser’s Phase 1 Environmental Review”) but only to the extent that Company Parties may do so without violating any confidentiality or other obligations to any third Person and only to the extent that Company Parties have the authority to grant such access without breaching any obligation or restriction binding on the Company Parties (or any of their Affiliates). In connection with the granting of such access, Purchaser agrees that Purchaser shall be liable to Sellers for any and all damage to the Company Properties arising out of or relating to Purchaser’s (or Purchaser’s Representatives’) inspection and access to the Company Properties. Purchaser shall, and shall cause Purchaser’s Representatives to, abide by the Company Parties’ (or any of their Affiliates’) implemented safety rules, regulations and operating policies of which they are informed in conducting Purchaser’s Phase 1 Environmental Review. The scope of work comprising Purchaser’s Phase 1 Environmental Review shall be limited to Phase I Activities and shall not include any sampling, testing or other invasive activities (collectively, “Invasive Activities”; hereinafter, Purchaser’s Phase 1 Environmental Review and any Invasive Activities performed shall be collectively referred to as “Purchaser’s Environmental Review”) unless such Invasive Activities are recommended by Purchaser’s Phase 1 Environmental Review, Purchaser first provides Sellers written notice and a written

59

schedule of the Invasive Activities planned to be conducted on the Company Properties, and Purchaser receives, in advance, written approval from Sellers and any required third parties for performance of the Invasive Activities as proposed by Purchaser. In the event Sellers or a required third party do not consent to any Invasive Activities proposed by Purchaser, Purchaser shall have the right, in its sole discretion, to exclude the Company Properties affected thereby, and the Cash Purchase Price shall be reduced at Closing by the Allocated Value of such Company Properties and such Company Properties shall be conveyed by the Company Parties to Sellers or their designee immediately prior to the Closing. Purchaser shall (i) consult with Sellers before conducting any work comprising Purchaser’s Environmental Review, (ii) perform all such work in a safe and workmanlike manner and so as to not unreasonably interfere with the Company Parties’ (or any of their Affiliates’) normal operations, (iii) comply with all applicable Laws and customary industry practices, and (iv) promptly and completely restore the Company Properties and repair to the approximate same condition any damage thereto resulting from Purchaser’s Environmental Review. The Company Parties shall have the right to have one or more representatives accompany Purchaser at all times during Purchaser’s Environmental Review, and Purchaser shall give the Company Parties at least forty-eight (48) hours’ notice prior to any visits by it (or any Purchaser’s Representatives) to the Company Properties. The Parties agree that all information discovered during Purchaser’s Environmental Review shall be governed by the terms of the Confidentiality Agreement.

(b) PURCHASER SHALL DEFEND, INDEMNIFY AND HOLD HARMLESS SELLERS AND THEIR CURRENT AND FORMER AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS, FROM AND AGAINST ANY AND ALL LIABILITIES ARISING OUT OF, RESULTING FROM, BASED ON, ASSOCIATED WITH, OR RELATING TO, IN ANY WAY, THE ACCESS AFFORDED TO PURCHASER PURSUANT TO THIS ARTICLE 6, REGARDLESS OF WHETHER SUCH LIABILITIES ARISE OUT OF OR RESULT FROM, SOLELY OR IN PART, THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OR VIOLATION OF LAW OF OR BY ANY SELLER OR COMPANY PARTIES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS, EXCEPTING ONLY LIABILITIES TO THE EXTENT RESULTING FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY SELLER, THE COMPANY PARTIES AND/OR THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS. THE FOREGOING INDEMNITY SHALL CONTINUE IN FULL FORCE AND EFFECT NOTWITHSTANDING ANY TERMINATION OF THIS AGREEMENT.

Section 6.3 Exclusive Remedy. The rights and remedies of Purchaser set forth in this Article 6 shall be Purchaser’s exclusive rights and remedies with respect to any defect of title (including any Title Defect), any Environmental Defect and any Environmental Liability with respect to the Company Properties, and the provisions of Article 11 shall not apply with respect to any defect in title (including any Title Defect), Environmental Defect or Environmental Liability, except with respect to a breach of the representations and warranties set forth in Section 3.8, Section 3.19, Section 3.21, Section 3.23, Section 3.24, Section 3.25, the covenants in Section 5.22 or with respect to Sections Section 11.1(b)(iii)(E) and (F).

60

Section 6.4 Notice of Title Defects and Title Benefits; Remedies.

(a) If Sellers discover any Title Benefit, or Purchaser discovers any Title Defect or Title Benefit, then such Party may (but shall have no obligation to) deliver to the other Party, on or prior to 5:00 p.m. Central time on the sixtieth (60th) day after the Execution Date (the “Title Defect Deadline”), a Title Notice with respect to such Title Benefit or Title Defect, as applicable. Except for claims pursuant to Article 11 with respect to a breach of (i) the representations and warranties set forth in Section 3.19, Section 3.21, Section 3.23, Section 3.24, Section 3.25 or Section 6.8 or (ii) the covenants in Section 5.22, from and after Closing, Sellers and Purchaser shall be deemed to have waived, and neither Purchaser nor Sellers, respectively, shall have any Liability for, any Title Benefit or Title Defect for which Purchaser or Sellers, respectively, has not received a Title Notice which substantially satisfies the requirements set forth in the definition of Title Notice on or before the Title Defect Deadline. For the avoidance of doubt, if Purchaser or Sellers fail to provide a Title Notice which substantially satisfies the requirements set forth in the definition of Title Notice, then the relevant Title Defect(s) or Title Benefit(s), as the case may be, shall be deemed waived.

(b) With respect to each Listed Interest for which Purchaser has asserted a Title Defect pursuant to a timely delivered Title Notice in substantial compliance with Section 1.2(hhhh) (each such Listed Interest, a “Title Defect Property”), Sellers shall have until the fifth (5th) Business Day after the Title Defect Deadline (the “Defect Response Date”) to notify Purchaser of those asserted Title Defects Sellers elect to cure (each, a “Cure Election”) and those asserted Title Defects Sellers dispute (each, a “Dispute Election”); provided that Sellers shall be entitled to make a Cure Election until the expiration of the Cure Period for any Title Defect for which Sellers made a Dispute Election so long as such Title Defect is cured prior to the expiration of the Cure Period.

(c) With respect to any Title Defect Property for which there is a timely delivered Cure Election, Sellers may cure the Title Defect asserted with respect to such Title Defect Property during the Cure Period. With respect to any Title Defect Property for which there is a timely delivered Dispute Election, the provisions of Section 6.7 shall apply and at the resolution of such Disputed Title Matter pursuant to Section 6.7, the Disputed Title Amount shall be delivered to Sellers or Purchaser pursuant to the decision of the Defect Arbitrators pursuant to Section 6.7.

(d) With respect to Title Defects asserted by Purchaser prior to Closing, the following shall apply:

61

(i) at Closing:

(A) if Purchaser and Sellers agree prior to Closing, Sellers shall cause such Title Defect Property (and all related or associated Company Earned Lease(s) and other Company Properties) to be conveyed by the Company Parties to Sellers or their designee immediately prior to the Closing, in which case, the Cash Purchase Price shall be reduced by the Allocated Value of such Title Defect Property (provided, however, the Farmout Agreements and Sellers’ interest with respect to any Company Unearned Leases thereunder shall not be excluded); or

(B) otherwise no such action shall be taken with respect to such Title Defect Property (and all related or associated Company Earned Lease(s) and other Company Properties), in which case, (1) if Sellers have not made a Cure Election or Dispute Election with respect to such Title Defect Property prior to Closing or if Sellers have made a Cure Election for such Title Defect Property, the Cash Purchase Price shall be decreased, at the Closing, by the Title Defect Amount asserted by Purchaser in good faith for such Title Defects or (2) if Sellers have made a Dispute Election for such Title Defect Property, then there will be no adjustment to the Cash Purchase Price at Closing and such matter shall be resolved pursuant to Section 6.7.

(ii) upon the expiration of the Cure Period:

(A) with respect to any Title Defect for which there was a reduction to the Cash Purchase Price pursuant to Section 6.4(d)(i)(B)(1) that Sellers have cured (or partially cured) prior to the expiration of the Cure Period, then the Cash Purchase Price shall be increased by the Title Defect Amount of such cured Title Defect Properties (or if the applicable Title Defect was only partially cured, the Cash Purchase Price shall be increased by an amount equal to the Title Defect Amount of such Title Defect Property less an amount equal to the portion of such Title Defect Amount that relates to the uncured portion of such Title Defect); and

(B) with respect to Title Defects asserted by Purchaser prior to Closing, if as of the expiration of the Cure Period, such Title Defect is a Disputed Title Matter that is subject to resolution pursuant to Section 6.7, then such Disputed Title Matter shall be resolved in accordance with Section 6.7.

62

(e) With respect to Title Defects asserted by Purchaser after Closing, the following shall apply:

(A) subject to Section 6.4(e)(D) below, if as of the expiration of the Cure Period, Sellers have cured any such Title Defect, then there shall be no adjustment to the Cash Purchase Price;

(B) subject to Section 6.4(e)(D) below, if as of the expiration of the Cure Period, Sellers have partially cured any such Title Defect, the Cash Purchase Price shall be decreased by an amount equal to the Title Defect Amount of such Title Defect Property less an amount equal to the portion of such Title Defect Amount that relates to the cured portion of such Title Defect;

(C) subject to Section 6.4(e)(D) below, if as of the expiration of the Cure Period, Sellers have not cured such Title Defect, the Cash Purchase Price shall be decreased by an amount equal to the Title Defect Amount of such Title Defect Property; and

(D) if as of the expiration of the Cure Period, such Title Defect is a Disputed Title Matter that is subject to resolution pursuant to Section 6.7, then such Disputed Title Matter shall be resolved in accordance with Section 6.7.

(f) The Parties agree that a cure (or a partial cure) may include (A) obtaining new leases to replace Allocated Value lost due to a Title Defect (“Replacement Acreage”), provided (1) such new leases cover lands in a governmental section in which the Company Parties’ own an interest and cover geologic depths that include all of the Target Depth or Target Depths being replaced, (2) if a Company Party is the Operator with respect to the Lease(s) being replaced, then a Company Party must be the Operator with respect to the new leases replacing each such Lease, (3) the value of the new leases must be equal to or greater than the per Net Mineral Acre Allocated Value of the Leases being replaced as to the applicable Target Depths, where the value of the new leases shall be equal to the product of (X) the average per Net Mineral Acre Allocated Value of the Company Party’s Leases in the applicable section multiplied by (Y) the Net Mineral Acres associated with such new leases, (4) each new lease must have no less Net Revenue Interest as the Lease being replaced and the other terms and conditions of the new leases shall be substantially similar to the terms of the Leases being replaced, including substantially similar surface use restrictions (provided, as to duration, a lease with at least a remaining three year paid-up primary term (from the Execution Date) shall be deemed substantially similar to a Lease held by production), (5) Title Defects relating to a Net Revenue Interest deficiency shall be cured with new leases with a Net Revenue Interest sufficient to cure such Title Defect, (6) Title Defects relating to a Net Mineral Acre deficiency shall be replaced with new leases with Net Mineral Acres sufficient to cure such Title Defect and (7) Title Defects relating to excess Working

63

Interest shall be replaced with new leases with Working Interests sufficiently low to cure such Title Defect and/or (B) obtaining additional Net Mineral Acres or Net Revenue Interest in a Lease to replace Allocated Value lost due to a Title Defect (“Replacement Interests”) provided such Lease is located in the same governmental section in which the applicable Title Defect Property is located. To the extent new leases or interests utilized as Replacement Acreage or Replacement Interests, respectively, contain interests in excess of the interest necessary to cure a given Title Defect, such excess interest shall be accounted for as a New Interest (but only to the extent otherwise meeting the requirements of Section 5.15 with respect to New Interests).

(g) Notwithstanding anything to the contrary set forth herein, in no event shall there be any remedies provided by Sellers, and Sellers shall not be responsible for, (i) any individual Title Defect for which the Title Defect Amount does not exceed Fifty Thousand Dollars ($50,000) (the “Title Threshold”) and (ii) any Title Defect with respect to which the Title Defect Amount exceeds the Title Threshold, unless and until (X) the aggregate of all such Title Defect Amounts that exceed the Title Threshold (excluding any Title Defect Amounts attributable to Title Defects that are cured by Sellers prior to the expiration of the Cure Period) less the aggregate of all Title Benefit Amounts that exceed the Title Threshold plus (Y) the aggregate of all Environmental Defect Amounts that remain uncured by Closing and that exceed the Environmental Threshold, exceeds an amount equal to one percent (1%) of the Unadjusted Purchase Price (the “Defect Deductible”), and then only to the extent that the aggregate of such Title Defect Amounts (less such Title Benefit Amounts) exceeds the Defect Deductible.

Section 6.5 Title Defect Amount; Title Benefit Amount.

(a) The amount by which the Allocated Value of any Listed Interest (or Listed Interests if multiple Listed Interests are affected) is reduced as a result of the existence of a Title Defect with respect thereto is the “Title Defect Amount”, which shall be determined in accordance with the following methodology, terms and conditions:

(i) if Purchaser and Sellers agree on the Title Defect Amount, then such amount shall be the Title Defect Amount;

(ii) if the Title Defect represents a decrease in (A) the actual Net Revenue Interest for any Company Well with respect to any portion of the Target Depths for such Company Well below (B) the Net Revenue Interest stated on Annex 3 for such Company Well for the Target Depths, then the Title Defect Amount shall be the product of (y) the Allocated Value for such Company Well multiplied by (z) one (1), minus a fraction, the numerator of which is the actual Net Revenue Interest for such Company Well and the denominator of which is the Net Revenue Interest for that Company Well stated on Annex 3;

(iii) if the Title Defect represents a decrease in (A) the actual Net Mineral Acres covered by a Lease (with respect to any portion of the Target Depths set forth on Annex 3 for such Lease) below (B) the Net Mineral Acres for such Lease stated on Annex 3 for the applicable Target Depth, then, with respect to that Target Depth

64

for that Lease, the Title Defect Amount shall be the product of (y) the Allocated Value of that Target Depth for such Lease multiplied by (z) one (1), minus a fraction, the numerator of which is the actual Net Mineral Acres covered by such Lease (with respect to that Target Depth) and the denominator of which is the Net Mineral Acres for such Lease stated on Annex 3 for that Target Depth;

(iv) if the Title Defect represents an increase in (A) the actual Lease Burdens for any Lease (with respect to any portion of the Target Depths set forth on Annex 3 for such Lease) above (B) the Lease Burdens stated on Annex 3 for such Lease for the applicable Target Depth, then, with respect to that Target Depth for that Lease, the Title Defect Amount shall be the product of (y) the Allocated Value of that Target Depth for such Lease multiplied by (z) one (1), minus a fraction, the numerator of which is the Lease Burdens for that Target Depth for such Lease stated on Annex 3 and the denominator is the actual Lease Burdens for that Target Depth for such Lease; provided that, notwithstanding anything contained in this Section 6.5(a)(iv) to the contrary, if the actual Lease Burdens for a Lease for the applicable Target Depth taking such Title Defect into account are greater than twenty-five percent (25%), then, unless the Lease Burdens shown on Annex 3 for such Lease for the applicable Target Depth are equal to the actual Lease Burdens for such Target Depth for such Lease, for each one percent (1%) increase in the actual Lease Burdens above the greater of twenty-five (25%) or the Lease Burdens shown on Annex 3 for such Target Depth for such Lease, the Title Defect Amount with respect to such one percent (1%) excess shall be equal to the amount set forth on Schedule 6.5(a)(iv) for the relevant percentage of Lease Burdens (such amount proportionately reduced for increments of less than one percent (1%), using the corresponding Title Defect Amount for each one percent (1%) increment for the relevant percentage of Lease Burdens as set forth on Schedule 6.5(a)(iv), and such amount not to exceed the Allocated Value of the applicable Target Depth for that Lease).

(v) if the Title Defect is based on a Lien upon a Lease or Company Well that is undisputed and liquidated in amount, then the amount of such Title Defect shall be the lesser of the amount necessary to remove such Lien from the affected Lease or Company Well or the Allocated Value of the affected Lease or Company Well;

(vi) if the Title Defect is based on an obligation, encumbrance, Lease Burden or charge upon or other defect in title to the affected Lease or Company Well of a type not described in Sections 6.5(a)(i), (ii), (iii), (iv) or (v), then, subject to the other provisions hereof, the Title Defect Amount shall be determined by the Parties in good faith, taking into account all relevant factors, including the following: (A) the Allocated Value of each affected Target Depth covered by that Lease or Company Well, (B) the portion of the affected Lease or Company Well affected by such Title Defect; (C) the legal effect of the Title Defect; (D) the potential economic effect of the Title Defect over the life of the affected Lease or Company Well; (E) the values placed upon the Title Defect by Purchaser and Sellers; and (F) such other reasonable factors as are necessary to make a proper evaluation;

65

(vii) the Title Defect Amount with respect to any Listed Interest shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder; and

(viii) notwithstanding anything to the contrary set forth herein, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Listed Interest shall not exceed the Allocated Value of such Listed Interest.

(b) The only remedy for Title Benefits is the netting against Title Defect Amounts which is only available for Title Benefit Amounts exceeding the Title Threshold. Each “Title Benefit Amount” shall be determined in accordance with the following methodology, terms and conditions:

(i) if Purchaser and Sellers agree on the Title Benefit Amount, then such amount shall be the Title Benefit Amount;

(ii) if the Title Benefit represents an increase in (A) the actual Net Revenue Interest for any Company Well with respect to the Target Depth for such Company Well over (B) the Net Revenue Interest stated on Annex 3 for such Company Well (and there is a corresponding increase in the Working Interest for such Company Well above the Working Interest stated on Annex 3 with respect to the Target Depth for such Company Well), then the Title Benefit Amount shall be the product of (y) the Allocated Value of such Company Well multiplied by (z) the result obtained by subtracting one (1) from a fraction, the numerator of which is the actual Net Revenue Interest for such Company Well with respect to the Target Depth for such Company Well and the denominator of which is the Net Revenue Interest for such Company Well stated on Annex 3;

(iii) if the Title Benefit represents an increase in (A) the actual Net Mineral Acres covered by a Lease with respect to either of the Target Depths described for such Lease on Annex 3, above (B) the Net Mineral Acres for that Target Depth for such Lease stated on Annex 3, then the Title Benefit Amount shall be the product of (y) the Allocated Value of that Target Depth for such Lease multiplied by (z) the result obtained by subtracting one (1) from a fraction, the numerator of which is the actual Net Mineral Acres covered by the Lease with respect to that Target Depth described for such Lease on Annex 3, and the denominator of which is the Net Mineral Acres for that Target Depth for such Lease stated on Annex 3; and

(iv) if the Title Benefit is not of a type described in Sections 6.5(b)(i), (ii) and (iii), or if the Title Benefit affects only a portion of the applicable Target Depth, then, subject to the other provisions hereof, the Title Benefit Amount shall be determined by the Parties in good faith, taking into account all relevant factors, including the following: (A) the Allocated Value of the affected Target Depth of

66

the affected Lease or Company Well, (B) the portion of the affected Target Depth of the affected Lease or Company Well affected by such Title Benefit; (C) the legal effect of the Title Benefit; (D) the potential economic effect of the Title Benefit over the life of the affected Lease or Company Well; (E) the values placed upon the Title Benefit by Purchaser and Sellers; and (F) such other reasonable factors as are necessary to make a proper evaluation.

Section 6.6 Notice of Environmental Defects; Remedies.

(a) If Purchaser discovers any Environmental Defect, then Purchaser may (but shall have no obligation to) deliver to Sellers prior to 5:00 p.m. Central time on the thirtieth (30th) day after the Execution Date (the “Environmental Defect Deadline”), an Environmental Notice with respect to such Environmental Defect. Notwithstanding any other provision in this Agreement, Purchaser shall be deemed to have waived, and Sellers shall have no Liability for, any Environmental Defect for which Sellers have not received an Environmental Notice on or before the Environmental Defect Deadline. For the avoidance of doubt, to the extent Purchaser fails to provide an Environmental Notice which substantially satisfies the requirements set forth in the definition of Environmental Notice, then the relevant Environmental Defect(s) shall be deemed waived.

(b) With respect to each Company Property for which Purchaser has asserted an Environmental Defect pursuant to a timely delivered Environmental Notice in substantial compliance with Section 1.2(hh) (each such Company Well or Company Earned Lease, an “Environmental Defect Property”), Sellers may elect (in their sole and absolute discretion, and in addition to Sellers’ rights under Section 6.6(c)) to complete the cure of such Environmental Defect Property prior to Closing in accordance with Section 6.6(c), in which event any adjustment to the Cash Purchase Price with respect to such Environmental Defect Property shall be made, if applicable, at the time of Closing in accordance with Section 6.6(c).

(c) With respect to any Environmental Defect Property, until the time of Closing, Sellers may, but shall have no obligation to, elect to dispute (each, a “Environmental Dispute Election”) the existence of the Environmental Defect asserted with respect to such Environmental Defect Property pursuant to the provisions of Section 6.7, in which case the Environmental Defect Amount shall be delivered by Purchaser into the Escrow Account at Closing (the “Disputed Environmental Amount”). With respect to any Environmental Defect Property for which there is a timely delivered Environmental Dispute Election the provisions of Section 6.7 shall apply and at the resolution of such Disputed Matters pursuant to Section 6.7, the Disputed Environmental Amount shall be delivered to Sellers or Purchaser pursuant to the decision of the Defect Arbitrators pursuant to Section 6.7. Subject to the 75% Uncured Provision, if, at the time of Closing, Sellers have cured the Environmental Defects affecting any Environmental Defect Property, then the Cash Purchase Price shall not be adjusted with respect to such Environmental Defect Property, or, if the Environmental Defects affecting any Environmental Defect Property were only partially cured, the Cash Purchase Price shall be decreased by an amount equal to the portion of such

67

Environmental Defect Amount that relates to the uncured portion of such Environmental Defects, or, if such Environmental Defects were not cured, the Cash Purchase Price shall be decreased by an amount equal to such Environmental Defect Amount that relates to such Environmental Defects. Notwithstanding anything set forth in this Section 6.6(c), if, at the time of Closing, any Environmental Defect Property has an Environmental Defect, the Environmental Defect Amount of which is seventy-five percent (75%) or more of the Allocated Value of such Environmental Defect Property, then, at the election of either Sellers or Purchaser and upon written notice given to the other Party prior to the Closing, such Environmental Defect Property (and all related or associated Company Earned Lease(s) and other Company Properties) will be excluded from the transaction contemplated hereby, in which event such Environmental Defect Property shall be conveyed by Company Parties to Sellers or their designee immediately prior to the Closing and the Cash Purchase Price shall be reduced by the Allocated Value of such Environmental Defect Property (the “75% Uncured Provision”).

(d) Notwithstanding anything to the contrary set forth herein, in no event shall there be any remedies provided by Sellers, and Sellers shall not be responsible for, (i) any individual Environmental Defect for which the Environmental Defect Amount does not exceed Seventy-Five Thousand Dollars ($75,000) (the “Environmental Threshold”) and (ii) any Environmental Defect with respect to which the Environmental Defect Amount exceeds the Environmental Threshold, unless and until (X) the aggregate of all such Environmental Defect Amounts that remain uncured by Closing and that exceed the Environmental Threshold plus (Y) the aggregate of all Title Defect Amounts that exceed the Title Threshold (excluding any Title Defect Amounts attributable to Title Defects that are cured prior to the expiration of the Cure Period) and less the aggregate of all Title Benefit Amounts that exceed the Title Threshold, exceeds the Defect Deductible, and then only to the extent that the aggregate of such Environmental Defect Amounts exceeds the Defect Deductible.

Section 6.7 Title and Environmental Dispute Resolution. If (i) Sellers have delivered a Dispute Election or the Parties cannot agree upon the existence of a Title Defect or Title Benefit, the adequacy of any Title Defect curative materials submitted to Purchaser, the Title Defect Amount with respect to any Title Defect or the Title Benefit Amount with respect to any Title Benefit (each, a “Disputed Title Matter”) or (ii) Sellers have delivered an Environmental Dispute Election or the Parties cannot agree upon the existence of an Environmental Defect, the adequacy of any Environmental Defect curative actions taken by Sellers, or the Environmental Defect Amount with respect to any Environmental Defect (each, a “Disputed Environmental Matter” and, together with any Disputed Title Matter, a “Disputed Matter”), then, in each case, the Disputed Matter shall be submitted to arbitration in accordance with the provisions of Exhibit C. Upon resolution of a Disputed Title Matter, if one of the Parties is required to make a payment to another Party, then such amount shall be paid within five (5) days after the resolution of such Disputed Matter.

Section 6.8 Special Warranty. Notwithstanding anything herein to the contrary, if Closing occurs, then effective as of the Closing Date and until the end of three years after the Closing Date (the “Survival Period”), Sellers, jointly and severally, represent and warrant to Purchaser and the Company Parties there is no Title Defect as to each Listed Interests with respect

68

to any conveyance, assignment, transfer, lien or encumbrance arising by, through or under Sellers, the Company Parties or any of their respective Affiliates, but not otherwise, subject, however, to the Permitted Encumbrances; provided, however, that, except with respect to any Liability of Sellers for any claim asserted in writing by Purchaser to Sellers in accordance with this Section 6.8 on or before the expiration of the Survival Period for breach of such special warranty, such special warranty shall cease and terminate at the end of such Survival Period. For purposes of Sellers’ special warranty of title, the value of the Listed Interests set forth in Annex 3 shall be deemed to be the Allocated Value thereof. Recovery on Sellers’ special warranty of title with respect to each Listed Interest shall be limited to the value of such Listed Interest set forth in Annex 3. Sellers shall be entitled to offset (without duplication) amounts attributable to any breach of Sellers’ special warranty of title with respect to any Listed Interest by the amount of Title Benefits with respect to such Listed Interest as to which Sellers give Purchaser written notice prior to the expiration of the Title Defect Deadline. For the avoidance of doubt, no Person shall have any right to assert any breach of Sellers’ special warranty of title set forth in this Section 6.8 to the extent that an adjustment to the Cash Purchase Price has previously been made for such Title Defect pursuant to this Article 6 or Damages have been recovered pursuant to Article 11 for a breach of the representations and warranties set forth in Section 3.8, Section 3.19, Section 3.21, Section 3.23, Section 3.24 or Section 3.25 or a breach of the covenants set forth in Section 5.22 pertaining to the same matter giving rise to a breach of the special warranty of title made pursuant to this Section 6.8. For the avoidance of doubt and notwithstanding anything in this Agreement to the contrary, the Title Threshold, the Defect Deductible, the limitations in the definition of “Damages”, Section 11.3(e) and Section 11.3(f) shall in no way limit any claim by Purchaser or the Company Parties pursuant to this Section 6.8.

76

Section 9.4 Access to Information.

(a) From and after Closing, each Seller shall grant to Purchaser (or its designees) reasonable access at all reasonable times to the information, books and records relating to a Company Party within the possession of Sellers (including work papers and correspondence with taxing authorities, but excluding work product of and attorney-client communications with any of Sellers’ legal counsel and personnel files), and shall afford Purchaser (or its designees) the right (at Purchaser’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit Purchaser (or its designees) to prepare Tax Returns, to conduct negotiations with Tax authorities, and to implement the provisions of, or to investigate or defend any claims between the Parties arising under, this Agreement.

(b) From and after Closing, Purchaser shall grant to Sellers (or Sellers’ designees) reasonable access at all reasonable times to the information, books and records relating to any Company Party within the possession of Purchaser or any Company Party (including work papers and correspondence with taxing authorities, but excluding work product of and attorney-client communications with any of Purchaser’s legal counsel and personnel files), and shall afford Sellers (or Sellers’ designees) the right (at Sellers’ expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit Sellers (or Sellers’ designees) to prepare Tax Returns, to conduct negotiations with, or contest deficiencies asserted by, Tax authorities, and to implement the provisions of, or to investigate or defend any claims between the Parties arising under, this Agreement.

(c) Each of the Parties hereto will preserve and retain all schedules, work papers and other documents within the Party’s possession relating to any Tax Returns of or with respect to Taxes of any Company Party or to any claims, audits or other proceedings with respect thereto until the latest of (i) the expiration of the statute of limitations (including extensions) applicable to the taxable period to which such documents relate, (ii) the final determination of any controversy with respect to such taxable period, (iii) the final determination of any payments that may be required with respect to such taxable period under this Agreement, and (iv) seven (7) years after the Closing Date.

(d) At either Purchaser’s or Sellers’ request, the other Party shall provide reasonable access to Purchaser’s or Sellers’, as the case may be, and their respective Affiliates’ (including the Company Parties’) personnel who have knowledge of the information described in this Section 9.4.

Section 9.5 Contest Provisions.

(a) From and after Closing, each of Purchaser, on the one hand, and Sellers, on the other hand (as applicable, the “Tax Indemnified Person”), shall notify the chief tax officer (or other appropriate person) of Sellers or Purchaser, as the case may be, in writing within fifteen (15) days of receipt by the Tax Indemnified Person of written notice of any pending or threatened audits, adjustments, claims, examinations,

77

assessments or other similar proceedings with respect to Taxes of any Company Party (a “Tax Audit”) which are likely to affect the Liability for Taxes of such other Party under this Agreement or otherwise. If the Tax Indemnified Person fails to give such timely notice to the other Party, it shall not be entitled to indemnification for any Taxes arising in connection with such Tax Audit if such failure to give notice materially adversely affects the other Party’s right to participate in the Tax Audit.

(b) If such Tax Audit relates to any Pre-Closing Period or Straddle Period for which only Sellers would be liable to indemnify Purchaser under this Agreement, Sellers shall, at their expense, conduct and control the defense and settlement of such Tax Audit. If such Tax Audit relates solely to any Post-Closing Period or Straddle Period for which only Purchaser would be liable under this Agreement, Purchaser shall conduct and control the defense and settlement of such Tax Audit.

(c) If such Tax Audit relates to Taxes for a Straddle Period for which both Sellers and Purchaser could be liable under this Agreement, to the extent practicable, such Tax items will be distinguished and each of Purchaser, on the one hand, and Sellers, on the other hand, shall control, at its own expense, the defense and settlement of those Taxes for which it is so liable. If such Tax Audit relates to a Straddle Period and any Tax item cannot be identified as being a Liability of only Sellers or Purchaser, or cannot be separated from a Tax item for which the other Party is liable, Sellers shall be entitled to control, at their own expense, the defense and settlement of the Tax Audit if Sellers so notify Purchaser within fifteen (15) days of notice of such Tax Audit, provided that Sellers defend the Tax items as reported on the relevant Tax Return in good faith as if Sellers were the only Party with an interest in the Tax item and provided further that Sellers shall not settle such matter without the prior written consent of Purchaser, which consent shall not be unreasonably withheld, conditioned or delayed. If Sellers do not elect to control the defense and settlement of such Tax Audit, Purchaser shall control the defense and settlement of such Tax Audit; provided, that Sellers shall pay any Tax for which it is otherwise liable under this Article 9. Any expenses from such Straddle Period Tax Audit that relate to a Tax item for which only Purchaser or Sellers are liable shall be borne by such Party. Any other expenses from such Straddle Period Tax Audit shall be borne by Purchaser and Sellers, respectively, in the same proportion as such related Taxes are or would be borne economically by Purchaser and Sellers.

(d) With respect to Pre-Closing Periods and Straddle Periods, any Party whose Liability for Taxes may be affected by a Tax Audit shall be entitled to participate at its expense in such defense and to employ counsel of its choice at its expense, and the Party controlling such Tax Audit shall not settle or compromise such Tax Audit without the other Party’s or Parties’, as applicable, prior written consent (not to be unreasonably withheld, conditioned or delayed).

(e) In the event of a conflict between the provisions of this Section 9.5 and any other provision of this Agreement, this Section 9.5 shall control.

78

Section 9.6 Post-Closing Actions Which Affect Sellers’ Tax Liability. Except to the extent required by applicable Laws, neither Purchaser, on the one hand, nor Sellers, on the other hand, shall, and they shall not permit their respective Affiliates (including the Company Parties) to, amend any Tax Return of any Company Party with respect to a Pre-Closing Period without the prior written consent of the other.

Section 9.7 Refunds.

(a) The amount of any refunds of Taxes of any Company Party for any Pre-Closing Period shall be for the account of Sellers. Purchaser agrees to pay to Sellers any such refund received (whether by payment, credit, offset or otherwise, and together with any interest thereon) after the Closing by Purchaser or its Affiliates, including the Company Parties, net of any reasonable costs or expenses incurred by Purchaser or its Affiliates in procuring such refund. Purchaser shall provide reasonable cooperation to Sellers and Sellers’ Affiliates in order to take all necessary steps to claim any such refund. Any such refund received by Purchaser, its Affiliates or any Company Party shall be paid to Sellers within thirty (30) days after such refund is received, net of any reasonable costs or expenses incurred by Purchaser or its Affiliates in procuring such refund. Purchaser agrees to notify Sellers within ten (10) days following the discovery of a right to claim any such refund and upon receipt of any such refund. Purchaser agrees, at Sellers’ expense, to (i) claim any such refund as soon as possible after the discovery of a right to claim a refund and (ii) furnish to Sellers all information, records and assistance necessary to verify the amount of the refund or overpayment.

(b) The amount of any refunds of Taxes of any Company Party for any Post-Closing Period shall be for the account of Purchaser. Sellers agree to pay to Purchaser any such refund received (whether by payment, credit, offset or otherwise, and together with any interest thereon), net of any reasonable costs or expenses incurred by Sellers or their Affiliates in procuring such refund, after the Closing by Sellers or their Affiliates, within thirty (30) days after such refund is received.

(c) Purchaser shall not, and shall cause the Company Parties not to, carry back any Tax item of such Company Party arising in any taxable period beginning after the Closing Date to a taxable year ending on or before the Closing Date.

Section 9.8 Cooperation.

(a) Each of Sellers and Purchaser shall provide the other Party with such cooperation and information as it reasonably may request with respect to the Company Parties in filing any Tax Return, amended Tax Return or claim for refund, determining a Liability for Taxes or a right to a refund of Taxes or participating in or conducting any audit or other proceeding in respect of Taxes. Each Party shall bear its own expenses in complying with the foregoing provisions of this Section 9.8(a).

(b) Purchaser and Sellers further agree, upon request, to use their reasonable efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the transactions contemplated hereby).

79

Section 9.9 Section 754 Election. Sellers shall, prior to the Closing, (a) cause each tax partnership that is scheduled with respect to Section 3.7(l) to either (i) have in effect a valid election under Section 754 of the Code for any taxable year that includes the Closing Date or (ii) obtain all necessary consents therefor; and (b) provide evidence satisfactory to Purchaser that the covenant set forth in clause (a) has been satisfied.

Section 9.10 Like-Kind Exchange. Purchaser may elect to treat the acquisition of the Acquired Interests as an exchange of like-kind property under Section 1031 of the Code (an “Exchange”) provided that the Closing shall not be delayed by reason of the Exchange. Sellers agree to use reasonable efforts to cooperate with Purchaser in the completion of such an Exchange including an Exchange subject to the procedures outlined in Treasury Regulation § 1.1031(k)-1 and/or Internal Revenue Service Revenue Procedure 2000-37. Purchaser shall have the right at any time prior to Closing to assign all or a part of its rights under this Agreement to a qualified intermediary (as that term is defined in Treasury Regulation § 1.1031(k)-1(g)(4)(iii)) or an exchange accommodation titleholder (as that term is defined in Internal Revenue Service Revenue Procedure 2000-37) to effect an Exchange. Each Party acknowledges and agrees that neither an assignment of Purchaser’s rights under this Agreement nor any other actions taken by Purchaser or any other Person in connection with the Exchange shall release any Party from, or modify, any of its Liabilities (including indemnity obligations to each other) under this Agreement, and no Party makes any representations as to any particular Tax treatment that may be afforded to any other Party by reason of such assignment or any other actions taken in connection with the Exchange. If Purchaser elects to treat the acquisition of the Acquired Interests as an Exchange, Purchaser shall be obligated to pay all additional costs incurred hereunder as a result of the Exchange, and in consideration for the cooperation of Sellers, Purchaser shall agree to pay all costs associated with the Exchange and to indemnify and hold Sellers, their Affiliates, and their respective former, current and future partners, members, shareholders, owners, officers, directors, managers, employees, agents and representatives harmless from and against any and all Liabilities and Taxes arising out of, based upon, attributable to or resulting from the Exchange or transactions or actions taken in connection with the Exchange that would not have been incurred by Sellers but for Purchaser’s Exchange election.

Section 9.11 Conversion of Felix Energy GP. On or before December 31, 2015, Sellers shall cause Felix Energy GP, a Delaware corporation, to be converted, by filing a certificate of conversion and a certificate of formation pursuant to Section 18-201 and Section 18-214 of the Delaware Limited Liability Company Act, into a Delaware limited liability company properly classified for U.S. federal income Tax purposes as an entity that is disregarded as separate from the Company in accordance with Treasury Regulations Section 301.7701-3.

ARTICLE 10

TERMINATION AND AMENDMENT

Section 10.1 Termination. This Agreement may be terminated at any time prior to Closing: (i) by the mutual prior written consent of Sellers and Purchaser; (ii) by Sellers or Purchaser, by written notice to the other Party, if the other Party is in material breach of any covenant or a representation in this Agreement, which breach would give rise to the failure of a condition set forth in Article 7 and is incapable of being cured, or is not cured, by such breaching Party within the earlier of (A) thirty (30) days following receipt of written notice from the non-

80

breaching Party of such breach or (B) the End Date; or (iii) by Sellers or Purchaser, by written notice to the other Party, if Closing has not occurred on or before March 31, 2016 (the “End Date”); provided, however, that no Party shall be entitled to terminate this Agreement under Section 10.1(ii) or Section 10.1(iii) if the Closing has failed to occur because such Party failed to perform or observe in any material respect its representations, warranties, covenants or agreements hereunder; provided further, however, that the End Date shall automatically be extended until the date that is 60 days after the original End Date if, as of the original End Date, all other conditions to the Closing are satisfied or capable of then being satisfied and the sole reason that the Closing has not been consummated is that the condition set forth in Section 7.1(a) of the TOM-STACK Purchase Agreement has not been satisfied.

Section 10.2 Effect of Termination. If this Agreement is terminated pursuant to Section 10.1, this Agreement shall become void and of no further force or effect (except for the provisions of Section 1.2, Section 3.12, Section 4.10, Section 5.1, Section 5.4, Article 10, Section 12.1, Section 12.2, Section 12.4, Section 12.7, Section 12.8, Section 12.9, Section 12.10, Section 12.11, Section 12.12, Section 12.13, Section 12.14, Section 12.15, Section 12.16, Section 12.17, Section 12.18, Section 12.19 and Section 12.20 and of the Confidentiality Agreement, all of which shall continue in full force and effect). Notwithstanding anything to the contrary in this Agreement, the termination of this Agreement under Section 10.1 shall not relieve any Party from Liability for any willful failure to perform or observe in any material respect any of its agreements or covenants contained herein that are to be performed or observed at or prior to Closing. In the event Sellers or Purchaser is entitled to terminate this Agreement under Section 10.1(ii) or (iii) and the other Party has willfully failed to perform or observe in any material respect any of its agreements or covenants contained herein which are to be performed or observed at or prior to Closing, then subject to Section 12.19, the non-breaching Party shall be entitled to all remedies available at law or in equity, including specific performance, and shall be entitled to recover court costs and attorneys’ fees in addition to any other relief to which such Party may be entitled (except as provided in Section 12.18 and Section 12.19).

ARTICLE 11

(c) Notwithstanding anything to the contrary contained in this Agreement, from and after Closing, Sellers’ and Purchaser’s exclusive remedy against each other with respect to breaches of the representations, warranties, covenants and agreements of the Parties contained in Articles 3, 4, 5, 6 and 9 and the affirmations of such representations, warranties, covenants and agreements contained in the certificates delivered by each Party at Closing pursuant to Section 8.2(b), Section 8.2(c) or Section 8.3(c), as applicable, is set forth in this Section 11.1, or with respect to Environmental Defects (but excluding any breach of the representations or warranties under Section 3.8(d)) or Title Defects, in Article 6. Except for the remedies contained in Article 6, this Section 11.1 and Section 10.2, and any other remedies available to the Parties at law or in equity for breaches of provisions of this Agreement other than Articles 3, 4, 5, 6 and 9, from and after the Closing, Sellers release, remise and forever discharge, waive and covenant not to sue Purchaser, the Company Parties (including claims against the Company Parties with respect to any breach by any Company Party of this Agreement), their Affiliates and all such Persons’ stockholders, officers, directors, employees,

83

agents, advisors and representatives, and Purchaser releases, remises and forever discharges, waives and covenants not to sue Sellers, their Affiliates and all such Persons’ stockholders, officers, directors, employees, agents, advisors and representatives, in each case, from or for any and all Damages based on, relating to or arising out of this Agreement or any Seller’s or Company Party’s ownership, use or operation of the assets of the E&P Business, or the condition, quality, status or nature of the assets of the E&P Business, including rights to cost recovery or contribution under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, claims under any other Environmental Laws, breaches of statutory and implied warranties, nuisance or other tort actions, rights to punitive damages, common law rights of contribution, or any rights under insurance policies issued or underwritten by the other Party or Parties or any of its or their Affiliates. Without limiting the generality of the preceding sentence, Purchaser agrees that from and after Closing its only remedy with respect to any Seller’s breach of its covenants and agreements in Articles 5 or 9 shall be the indemnity of Sellers in Section 11.1(b), as limited by the terms of this Article 11.

(d) “Damages” means, subject to Section 12.18, the amount of any actual liability, loss, cost, expense, claim, award, judgment, violations, filings, investigations, administrative proceedings, actions, causes of action, suits, other legal proceedings, assessments, damages, deficiencies, Taxes, penalties, fines, obligations, responsibilities, payments and other charges (including costs and expense of operating the Company Properties) of any kind or character (whether known or unknown, fixed or unfixed, conditional or unconditional, choate or inchoate, liquidated or unliquidated, secured or unsecured, accrued, absolute, contingent, or other legal theory) incurred or suffered by any Indemnified Person arising out of or resulting from the indemnified matter, whether attributable to personal injury, death, property or natural environmental resource damage, contract claims, torts or otherwise, including reasonable fees and expenses of attorneys, consultants, accountants or other agents and experts reasonably incident to matters indemnified against, and the costs of Remediation of such matters, and the costs of enforcement of the indemnity. Notwithstanding the foregoing, except in the event of fraud or willful breach of this Agreement by any Seller, Purchaser shall not be entitled to indemnification under Section 11.1(b)(ii) (other than with respect to the Fundamental Representations and the representations and warranties in Section 3.7 (Taxes)), for any Liability that does not individually exceed One Hundred Fifty Thousand Dollars ($150,000).

(e) Any claim for indemnity under this Section 11.1 by any current or former Affiliate, director, officer, employee or agent must be brought and administered by the applicable Party to this Agreement. No Indemnified Person other than Sellers and Purchaser shall have any rights against any Seller or Purchaser under the terms of this Section 11.1 except as may be exercised on its behalf by Purchaser or Sellers, as applicable, pursuant to this Section 11.1(e). Each of Sellers and Purchaser may elect to exercise or not exercise indemnification rights under this Section 11.1(e) on behalf of the other Indemnified Persons affiliated with it in its sole discretion and shall have no Liability to any such other Indemnified Person for any action or inaction under this Section 11.1(e).

84

(f) After becoming aware of any fact, event, circumstance or condition that has given rise to or would reasonably be expected to give rise to any Damages, the Indemnified Persons shall use commercially reasonable efforts to mitigate Damages, for which efforts such Indemnified Persons are entitled or may be entitled to indemnification under this Section 11.1.

(g) The Parties shall treat, for U.S. federal income Tax purposes, any amounts paid under this Article 11 as an adjustment to the Purchase Price, which adjusted shall be reflected in the Final Section 2.2(b) Schedule in the manner provided in Section 2.2.

Section 11.2 Indemnification Actions. All claims for indemnification under Section 11.1 shall be asserted and resolved as follows:

(a) For purposes of this Article 11, the term “Indemnifying Person” when used in connection with particular Damages means the Person having an obligation to indemnify another Person or Persons with respect to such Damages pursuant to this Article 11, and the term “Indemnified Person” when used in connection with particular Damages means a Person having the right to be indemnified with respect to such Damages pursuant to this Article 11 (including those Persons identified in Section 11.1(e)).

(b) To make a claim for indemnification under Section 11.1, an Indemnified Person shall notify the Indemnifying Person of its claim, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). The amount claimed shall be paid by the Indemnifying Person to the extent required herein within thirty (30) days after receipt of the Claim Notice, or after the amount of such payment has been finally established, whichever last occurs. In the event that the claim for indemnification is based upon a claim by a third Person against the Indemnified Person (a “Claim”), the Indemnified Person shall provide its Claim Notice within thirty (30) days after the Indemnified Person has received a written claim from such third Person and shall enclose a copy of all papers (if any) served with respect to the Claim; provided that the failure of any Indemnified Person to give notice of a Claim as provided in this Section 11.2 shall not relieve the Indemnifying Person of its obligations under Section 11.1 except to the extent such failure materially prejudices the Indemnifying Person’s ability to defend against the Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(c) In the case of a claim for indemnification based upon a Claim, the Indemnifying Person shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies its obligation to defend the Indemnified Person against such Claim under this Article 11. The Indemnified Person may, during such thirty (30) day period and upon ten (10) days’ prior written notice to the Indemnifying Person, file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Person and that is not prejudicial to the Indemnifying Person.

85

(d) If the Indemnifying Person admits its obligation, it shall have the right and obligation to defend, at its sole cost and expense, the Claim, and the Indemnifying Person shall conduct such defense diligently with counsels reasonably satisfactory to the Indemnified Person. The Indemnified Person may retain separate co-counsel at its sole cost and expense and participate in the defense of the Claim. Notwithstanding the foregoing, if counsel for the Indemnified Person reasonably determines that there is a conflict between the positions of the Indemnifying Person and the Indemnified Person in conducting the defense of such Claim or that there are legal defenses available to such Indemnified Person different from or in addition to those available to the Indemnifying Person, then one counsel for the Indemnified Person shall be entitled, if the Indemnified Person so elects, to participate in or conduct the defense to the extent reasonably determined by such counsel to protect the interests of the Indemnified Person, at the expense of the Indemnifying Person; provided that in no event shall the Indemnifying Person be required to pay the fees and expenses of more than one counsel selected by the Indemnified Person. If requested by the Indemnifying Person, the Indemnified Person agrees to cooperate in contesting any Claim which the Indemnifying Person elects to contest (provided, however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person). The Indemnified Person may participate in, but not control, any defense or settlement of any Claim controlled by the Indemnifying Person pursuant to this Section 11.2(d). No settlement of a Claim may be made by the Indemnifying Person without the written consent of the Indemnified Person, such consent not to be unreasonably withheld.

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

(f) In the case of a claim for indemnification not based upon a Claim, the Indemnifying Person shall have thirty (30) days from its receipt of the Claim Notice to (i) completely cure the Damages complained of, (ii) admit its obligation to provide indemnification with respect to such Damages or (iii) dispute the claim for such Damages.

Representations, warranties, covenants and agreements shall be of no further force and effect after the date of the expiration of a right to assert an indemnification claim with respect thereto, provided that there shall be no termination of any bona fide claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to the applicable expiration date.

(d) The indemnities in Section 11.1(a)(ii), Section 11.1(a)(iii), Section 11.1(b)(i) and Section 11.1(a)(ii) shall terminate as of the termination date of each respective representation, warranty, covenant or agreement that is subject to indemnification, except in each case as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Person on or before such termination date. The indemnity in Section 11.1(a)(i) shall continue without time limit. The indemnity in Section 11.1(b)(iii) shall continue in accordance with Section 11.3(c).

87

(e) Except in the event of fraud or willful breach of this Agreement by any Seller, no Seller shall have any Liability for any indemnification under Section 11.1(b)(ii), other than with respect to the Fundamental Representations and the representations and warranties in Section 3.7 (Taxes), until and unless the aggregate amount of the Liability for all Damages for which Claim Notices are delivered by Purchaser exceed Nineteen Million Dollars ($19,000,000), and then only to the extent such Damages exceed such amount.

(f) Notwithstanding anything to the contrary contained elsewhere in this Agreement, except in the event of fraud or willful breach of this Agreement by any Seller, no Seller shall be required to indemnify Purchaser under Section 11.1(b)(ii), other than with respect to the Fundamental Representations and the representations and warranties in Section 3.7 (Taxes), for aggregate Damages in excess of One Hundred Forty Two Million Five Hundred Thousand Dollars ($142,500,000).

(g) Notwithstanding anything herein to the contrary, for purposes of determining the amount of any Damages (but not for the purpose of determining whether or not such representation or warranty has been breached) for which any Indemnifying Person is obligated to indemnify under Section 11.1(a)(iii) or Section 11.1(b)(ii), such Damages shall be determined and calculated by excluding and without giving effect to any qualifiers as to materiality or Material Adverse Effect set forth in any representation or warranty or any closing certificate delivered pursuant to Section 8.2(b), Section 8.2(c) or Section 8.3(c).

(h) The amount of any Damages for which an Indemnified Person is entitled to indemnity under this Article 11 shall be reduced by the amount of insurance proceeds actually realized by the Indemnified Person or its Affiliates with respect to such Damages (net of any collection costs, including all the costs and expenses incurred by third parties in investigating, prosecuting, defending and collecting such recovered amount and, any deductibles paid to obtain insurance coverage, and excluding the proceeds of any insurance policy issued or underwritten by the Indemnified Person or its Affiliates, any retrospective insurance policies and any captive insurance policies).

(i) Notwithstanding anything to the contrary contained herein, all payments made or to be made under this Article 11 to Purchaser shall be made by Sellers by payment in cash and not via the return of any Ultimate Parent Shares.

(j) Notwithstanding anything to the contrary in this Agreement, no Party shall have any Liability for, and shall not be required to pay to any other Party, any amounts pursuant to this Agreement to the extent such amounts were actually taken into account in determining any other amounts actually paid between Sellers and Purchaser pursuant to this Agreement, including, but not limited to, in determining the Effective Time Net Working Capital and any other adjustments to the Unadjusted Purchase Price described herein.

88

Section 11.4 Escrow Claims.

(a) Subject to the applicable limitations set forth in Article 6, any amounts due by Sellers to Purchaser for any Title Defect shall be first satisfied from the Escrow Amount; provided, however, if the aggregate amount of the Title Defects exceeds Ninety Five Million Dollars ($95,000,000), Purchaser may, in its sole discretion, require a payment from Sellers for such excess Title Defects rather than from the remaining Escrow Amount. Subject to the applicable limitations set forth in this Article 11, any amounts due by a Seller to Purchaser pursuant to this Article 11 will be first satisfied from the Escrow Amount. To the extent that Purchaser is determined to be owed by Sellers amounts in excess of the Escrow Amount, Purchaser may seek payment for such amounts from Sellers.

(b) If Sellers do not dispute any claim made by Purchaser against Sellers, at Purchaser’s written election, Sellers and Purchaser shall provide written instructions to the Escrow Agent in accordance with the Escrow Agreement to disburse to Purchaser the amount of the undisputed claim. If Sellers do dispute any claim made by Purchaser, then upon final determination of the Title Defect Amount or Liability (or a settlement between the applicable Parties), as applicable, with respect to such claim, at Purchaser’s written election, Sellers and Purchaser shall provide written instructions to the Escrow Agent to disburse to Purchaser the amount determined by such final determination or settlement to be due and which amount is then remaining in the Escrow Account of Sellers.

(c) On the date that is five (5) Business Days after the Determination Date, Purchaser and Sellers shall instruct the Escrow Agent to release to Sellers the then existing amount of the Escrow Amount, save and except (i) One Hundred Forty Two Million Five Hundred Thousand Dollars ($142,500,000) plus (ii) the aggregate amount of all Disputed Title Amounts that have not been resolved as of such date. On the date that is nine (9) months after the Closing Date, Purchaser and Sellers shall instruct the Escrow Agent to release to Sellers the then existing amount of the Escrow Amount, save and except (x) Ninety-Five Million Dollars ($95,000,000), plus (y) the aggregate amount of all unsatisfied claims for indemnification that Purchaser has made against Sellers on or before such date pursuant to this Article 11 and which are subject to satisfaction (in whole or in part) from the Escrow Amount and plus (z) the aggregate amount of all Disputed Title Amounts that have not been resolved as of such date. On the date that is twelve (12) months after the Closing Date, Purchaser and Sellers shall instruct the Escrow Agent to release to Sellers the then existing amount of the Escrow Amount, save and except (y) the aggregate amount of all unsatisfied claims for indemnification that Purchaser has made against Sellers on or before such date pursuant to this Article 11 and which are subject to satisfaction (in whole or in part) from the Escrow Amount plus (z) the aggregate amount of all Disputed Title Amounts that have not been resolved as of such date.

(d) At any time, the Parties may jointly instruct, in the manner provided in the Escrow Agreement, the Escrow Agent to transfer all or a portion of the remaining balance of the Escrow Account to either Sellers or Purchaser, as the Parties may agree.

(c) Purchaser, for a period of seven (7) years following the Closing (and subject to Purchaser’s additional obligations under Section 9.4(c)), shall:

92

(ii) provide Sellers, their Affiliates, and their respective officers, employees and representatives with access, during normal business hours, to materials received or produced after Closing relating to:

Section 12.7 Governing Law. This Agreement will be interpreted, construed and enforced in accordance with the laws of the State of Oklahoma, without giving effect to any rules or principles of conflicts of law that might otherwise refer to the laws of another jurisdiction.

Section 12.8 Dispute Resolution. The Parties agree that irreparable damage would occur if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that, except as provided in Section 12.19, each of the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement exclusively in the state or federal courts located in Harris County, Texas.

No waiver of, or consent to a change in, any of the provisions of this Agreement shall be deemed or shall constitute a waiver of, or consent to a change in, other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided.

Section 12.11 Assignment. Except as set forth in Section 9.10, no Party shall assign or otherwise transfer all or any part of this Agreement, nor shall any Party delegate any of its rights or duties hereunder, without the prior written consent of the other Parties and any transfer or delegation made without such consent shall be void; provided, however, (i) following Closing, any Seller shall have the right to assign its rights under this Agreement to an Affiliate so long as such Affiliate or Affiliates assume all of such Seller’s obligations hereunder, but such assignment will not relieve such Seller of its obligations hereunder in the event of the failure of performance by such assignee and (ii) Purchaser shall have the right to assign its rights under this Agreement to an Affiliate so long as such Affiliate or Affiliates assume all of Purchaser’s obligations hereunder, but such assignment will not relieve Purchaser of its obligations hereunder in the event of the failure of performance by such assignee. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and assigns.

Section 12.12 Entire Agreement. The Confidentiality Agreement, this Agreement, the Escrow Agreement, the Confidentiality and Non-Competition Agreements, the Registration Rights Agreement and the documents to be executed hereunder and the Exhibits, Annexes and Schedules attached hereto constitute the entire agreement among the Parties pertaining to the subject matter hereof, and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties pertaining to the subject matter hereof.

Section 12.15 Headings. Headings have been provided for the sections of this Agreement, the Schedules, Annexes and Exhibits for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.

Section 12.18 Limitation on Damages. NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, THE PARTIES ACKNOWLEDGE THAT THIS AGREEMENT DOES NOT AUTHORIZE EITHER SELLERS OR PURCHASER TO MAKE CLAIMS, INCLUDE IN CALCULATION OR SUE FOR OR COLLECT FROM THE OTHER PARTY ITS OWN PUNITIVE, CONSEQUENTIAL, SPECIAL OR INDIRECT DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY (OTHER THAN PUNITIVE, CONSEQUENTIAL, SPECIAL OR INDIRECT DAMAGES SUFFERED BY THIRD PERSONS FOR WHICH RESPONSIBILITY IS ALLOCATED

95

BETWEEN THE PARTIES PURSUANT TO THE TERMS OF THIS AGREEMENT), AND EACH OF SELLERS AND PURCHASER EXPRESSLY WAIVES FOR ITSELF AND ON BEHALF OF ITS AFFILIATES, ANY AND ALL CLAIMS IT MAY HAVE AGAINST THE OTHER PARTY FOR ITS OWN SUCH DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 12.19 Specific Performance. Each of the Parties acknowledges that its obligations hereunder are unique and that remedies at law, including monetary damages, will be inadequate in the event it should default in the performance of its obligations under this Agreement. Accordingly, in the event of any breach of any agreement, representation, warranty or covenant set forth in this Agreement, Purchaser, in the case of a breach by Sellers or any Company Party, and Sellers, in the case of a breach by Purchaser, may be entitled to equitable relief, without the proof of actual damages, including in the form of an injunction or injunctions or orders for specific performance to prevent breaches of this Agreement and to order the defaulting Party to affirmatively carry out its obligations under this Agreement, and each of the Parties hereby waives any defense to the effect that a remedy at law would be an adequate remedy for such breach. Such equitable relief shall be in addition to any other remedy to which each of the Parties are entitled to at law or in equity as a remedy for such nonperformance, breach or threatened breach. Each of the Parties hereby waives any requirements for the securing or posting of any bond with such equitable remedy. The foregoing shall not be deemed to be or construed as a waiver or election of remedies by any of the Parties, each of whom expressly reserves any and all rights and remedies available to it at law or in equity in the event of any breach or default by the others under this Agreement prior to the Closing. Notwithstanding the foregoing, in no event shall Sellers be entitled to exercise the rights and remedies set forth in this Section 12.19 in connection with any failure of Purchaser or Parent to consummate the Closing.

Section 12.20 Time of Essence. This Agreement contains a number of dates and times by which performance or the exercise of rights is due, and the Parties intend that each and every such date and time be the firm and final date and time, as agreed. For this reason, each of Sellers and Purchaser hereby waives and relinquishes any right it might otherwise have to challenge its failure to meet any performance or rights election date applicable to it on the basis that its late action constitutes substantial performance, to require the other Party to show prejudice, or on any equitable grounds. Without limiting the foregoing, time is of the essence in this Agreement. If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date which is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during which notice is required to be given or action taken) shall be the next day which is a Business Day.
