(vii) to the extent that Seller or any of its Affiliates has under-delivered any Hydrocarbons as of the Effective Time including as shown with respect to the net Pipeline Imbalances set forth in Schedule 7.10, as complete and final settlement of all such Pipeline Imbalances attributable to the Conveyed Interests, an amount equal to the product of the under-delivered gaseous Hydrocarbon volumes times $1.50/MMBtu;

(viii) an amount equal to Suspense Funds that are held by Seller or any of its Affiliates as of the Closing Date or a date after Closing when the Liability to such Suspense Funds are transferred from Seller to Buyer, in each case, in accordance with Section 9.8;

(ix) the Allocated Other Working Interest Owner Amount if the Other Working Interest Owner Interest is not acquired by Seller prior to Closing; and

(x) any other amount provided for elsewhere in this Agreement as a downward adjustment to the Purchase Price or otherwise agreed upon in writing by Seller and Buyer as a downward adjustment to the Purchase Price.

3.4 Adjustment Methodology. When available, actual figures will be used for the adjustments to the Purchase Price at Closing. To the extent actual figures are not available, good faith estimates (including those with respect to expenses and revenues) will be used subject to final adjustments in accordance with Section 3.6 and Section 3.7.

3.5 Preliminary Settlement Statement. Not later than 5 Business Days prior to the Scheduled Closing Date, Seller shall prepare (in good faith and in accordance with the provisions of this Agreement) and submit to Buyer for review a draft settlement statement (the “Preliminary Settlement Statement”) that shall set forth the Adjusted Purchase Price, reflecting each adjustment made in accordance with this Agreement as of the date of preparation of such Preliminary Settlement Statement and the calculation of the adjustments used to determine such amount (including as a result of the EnLink Agreements to be executed and delivered at Closing), together with (x) reasonable supporting summary documentation and (y) the designation of Seller’s accounts for the wire transfers of funds as set forth in Section 3.1 and Section 12.3(g). Within two Business Days after receipt of the Preliminary Settlement Statement, Buyer may (without waiving any of its rights or remedies under this Agreement or otherwise), but shall not be obligated to, deliver to Seller a written report containing all changes with the explanation therefor that Buyer proposes to be made to the Preliminary Settlement Statement (based upon Buyer’s knowledge at such time). The Parties shall in good faith attempt to agree on the Preliminary Settlement Statement as soon as possible after Seller’s receipt of Buyer’s written report. The Preliminary Settlement Statement, as agreed upon by the Parties, will be used to adjust the Purchase Price at Closing; provided that if the Parties do not agree on an adjustment set forth in the Preliminary Settlement Statement prior to the Closing, the amount of such adjustment set forth in the Preliminary Settlement Statement as presented by Seller (as modified by any subsequent agreements by the Parties) will be used to adjust the Purchase Price at Closing, absent manifest error.

3.6 Final Settlement Statement.

(a) On or before 120 days after the Closing, Seller shall deliver to Buyer a final settlement statement (the “Final Settlement Statement”) prepared by Seller in good faith based on actual income and expenses during the Interim Period and which takes into account all final adjustments made to the Purchase Price and shows the resulting final Adjusted Purchase Price (the “Final Price”), which Final Settlement Statement shall include reasonable supporting summary documentation. The Final Settlement Statement shall set forth the actual proration of the amounts required by this Agreement. As soon as practicable, and in any event within 30 days after receipt of the Final Settlement Statement, except with respect to the matters addressed in Section 5.3(j) and Section 6.1(f) (if applicable), Buyer will deliver to Seller a written report containing any proposed changes to the Final Settlement Statement and an explanation of

10

any such changes and the reasons therefor (the “Dispute Notice”). Any matters included in a Dispute Notice shall be resolved pursuant to Section 3.7 and as resolved shall become part of the Final Settlement Statement and Final Price, as applicable. Any changes not so specified in the Dispute Notice shall be deemed waived and Seller’s determinations with respect to all such elements of the Final Settlement Statement that are not addressed specifically in the Dispute Notice shall prevail. If Buyer fails to timely and properly deliver a Dispute Notice to Seller containing changes Buyer proposes to be made to the Final Settlement Statement, the Final Settlement Statement as delivered by Seller and the Final Price set forth therein will be deemed to be correct and mutually agreed upon by the Parties, and will, without limiting Section 15.2(c), be final and binding on the Parties and not subject to further audit or arbitration. If the Adjusted Purchase Price as paid at Closing pursuant to the Preliminary Settlement Statement is less than the Final Price, then, subject to Section 5.3(j) and Section 6.1(f) (if applicable), such shortage shall be paid by Buyer to Seller within 10 days after final determination of such owed amounts in accordance herewith. If the Adjusted Purchase Price as paid at Closing pursuant to the Preliminary Settlement Statement is more than the Final Price, then, subject to Section 5.3(j) and Section 6.1(f) (if applicable), such overage shall be paid by Seller to Buyer within 10 days after final determination of such owed amounts in accordance herewith. All amounts paid by any Party pursuant to this Section 3.6 shall be delivered in United States currency by wire transfer of immediately available funds to the account specified in writing by the relevant Party.

(b) At the Closing, if applicable, Buyer shall deposit into the Escrow Account an amount equal to the Defect Escrow Amount. The “Defect Escrow Amount” shall mean (i) the aggregate amount of Title Defect Amounts asserted by Buyer with respect to all uncured Title Defects that were timely and properly asserted by Buyer pursuant to Section 5.3(a) and that Seller has elected to cure in good faith or are the subject of a Title Dispute (including any dispute as to whether Seller has cured such asserted Title Defects), plus (ii) the Remediation Amounts or Allocated Values, as applicable, asserted by Buyer for all uncured Environmental Defects that were timely and properly asserted by Buyer pursuant to Section 6.1(a) and that are the subject of a Disputed Environmental Matter (including any dispute as to whether Seller has cured such asserted Environmental Defects or as to whether Seller or Buyer is entitled to the remedy under Section 6.1(c)(ii)), less (iii) to the extent offsetting the Title Defect Amounts, the aggregate amount of Title Benefits Amounts asserted by Seller with respect to all Title Benefits that were timely and properly asserted by Seller pursuant to Section 5.3(b) and that Buyer has conceded or are the subject of a Title Dispute, in each case as applicable, after application of the Individual Title Defect Threshold or the Individual Environmental Threshold, as applicable, and (without duplication of the application thereof) the Title Defect Deductible, the Environmental Defect Deductible and other limitations set forth in Section 5.3(i) or Section 6.1(e), as applicable; provided that in no event shall the Defect Escrow Amount be less than zero. The Defect Escrow Amount shall be released from time to time to the Party entitled to such amount as determined pursuant to this Agreement, and the Parties shall instruct the Escrow Agent accordingly. Subject to the Parties’ rights under Section 5.3(j) and Section 6.1(f), as applicable, to the extent a Title Defect or Environmental Defect is cured or Remediated, as applicable, prior to the Title Defect Cure Deadline or Environmental Defect Cure Deadline, as applicable, and the Title Defect Amount, Remediation Amount or Allocated Value, as applicable, for the applicable Title Defect Property or Environmental Defect Property is part of the Defect Escrow Amount, then such Title Defect Amount, Remediation Amount or Allocated Value, as applicable, to the extent corresponding to such cure shall be released to Seller. Subject to the Parties’ rights under Section 5.3(j) and Section 6.1(f), as applicable, to the extent a Title Defect or Environmental Defect is not cured or Remediated, as applicable, prior to the Title Defect Cure Deadline or Environmental Defect Cure Deadline, as applicable, and the Title Defect Amount, Remediation Amount or Allocated Value, as applicable, for the applicable Title Defect Property or Environmental Defect Property is part of the Defect Escrow Amount, then such Title Defect Amount, Remediation Amount or Allocated Value, as applicable, to the extent corresponding to such failure to cure shall be released to (A) Seller or Buyer, as applicable, in accordance with any agreement between the Parties or (B) to the Party entitled to such amount upon final resolution of each unresolved Title Dispute or unresolved Disputed Environmental Matter pursuant to Section 5.3(j) or Section 6.1(f), as applicable.

11

(c) Notwithstanding anything to the contrary in this Agreement (including, for purposes of clarity, this Section 3.6), excepting those matters for which a Party is obligated to provide indemnification pursuant to Article XIII or under Section 2.3(b) or Section 15.2(e), if the Final Price set forth in the Final Settlement Statement is mutually agreed upon by Seller and Buyer or determined pursuant to Section 3.6(a), (i) the Final Settlement Statement and the Final Price shall, without limiting Section 15.2(c), be final and binding on the Parties, and, without limitation of Seller’s indemnity obligations with respect to the Specified Obligations, shall be the final accounting for any and all Operating Expenses and there shall be no adjustment for, or obligation to pay, any Operating Expenses between the Parties following the Final Settlement Statement and (ii) after the date that is two years following the Closing Date, there shall be no obligation of the Parties to account to one another for proceeds and revenues with respect to any Hydrocarbons produced from and/or allocated to the Conveyed Interests prior to the Effective Time.

3.7 Disputes.

(a) If Seller and Buyer are unable to resolve the matters addressed in a Dispute Notice (if any), for a 30-day period following written notice from either Party, an officer or representative designated by each Party shall attempt to resolve such dispute.

(b) If Seller and Buyer are unable to resolve their dispute within the period set forth in Section 3.7(a), either Party may initiate the arbitration process set forth in this Section 3.7(b) by sending a written notice to the other Party (the “Arbitration Notice”) within 20 days of the expiration of the 30-day period described in Section 3.7(a). Each Party shall, within 14 Business Days after the delivery of the Arbitration Notice, summarize its position with regard to such dispute in a written document of 20 pages or less and submit such summaries to the Houston, Texas office of Deloitte Touche Tohmatsu Limited, or such other Person as the Parties may mutually select (the “Accounting Arbitrator”), together with the Dispute Notice, the Arbitration Notice, the Final Settlement Statement and any other documentation such Party may desire to submit. Within 20 Business Days after receiving the Parties’ respective submissions, the Accounting Arbitrator shall render a decision choosing either Seller’s position or Buyer’s position with respect to each matter addressed in any Dispute Notice, based on the materials submitted to the Accounting Arbitrator as described above. Once appointed, the Accounting Arbitrator shall have no ex parte communication with either Party related to the Dispute Notice. Any decision rendered by the Accounting Arbitrator pursuant hereto shall, without limiting Section 15.2(c), be final, conclusive and binding on Seller and Buyer and will be enforceable against the Parties in any court of competent jurisdiction. The Accounting Arbitrator shall act as an expert for the limited purpose of determining the specific dispute submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter, except as otherwise provided in the following sentence. The costs of the Accounting Arbitrator and the reasonable legal costs and other expenses incurred by the Parties in connection with the arbitration shall be borne pro rata between the Parties with each Party being responsible for such costs and expenses to the extent the Accounting Arbitrator has not selected such Party’s position on an aggregate dollar basis with respect to all amounts submitted for resolution by the Accounting Arbitrator.

3.8 Allocated Values. Solely for the purposes of determining the value of Conveyed Interests in connection with any Title Defect, Environmental Defect, Preferential Purchase Right, Required Consent, Casualty Loss and/or breach of Special Warranty under this Agreement, Buyer and Seller have allocated the Purchase Price among (a) the Leases set forth on Exhibit A, (b) the Wells set forth on Exhibit B, (c) the Conveyed Interests identified on Schedule I-2 and (d) the Conveyed Interests identified on Schedule I-3. The value so allocated to (w) a particular Lease identified on Exhibit A, (x) a particular Well identified on Exhibit B, (y) a particular Conveyed Interest identified on Schedule I-2 or (z) a particular Conveyed Interest identified on Schedule I-3 may be referred to as “Allocated Value” for that Lease, Well or Conveyed Interest, as applicable. Buyer and Seller agree that such allocation is reasonable and shall not take any position inconsistent therewith, including in notices to holders of Preferential Purchase Rights. Seller, however, makes no representations or warranties as to the accuracy of such value or allocation.

12

3.9 Withholding. Buyer shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Agreement such amounts as may be required to be deducted and withheld with respect to Taxes; provided, however, other than with respect to any withholding as a result of Seller’s failure to provide the forms described in Section 12.2(j), Buyer shall provide at least five Business Days’ written notice to Seller if Buyer intends to withhold any amounts under this Section 3.9. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made by Buyer.

ARTICLE IV

ACCESS / DISCLAIMERS

4.1 Access.

(a) From and after the Execution Date until the earlier to occur of (x) the Closing Date and (y) the date on which the Agreement is terminated in accordance with its terms, but subject to the other provisions of this Section 4.1 and obtaining any required consents of any applicable Third Parties (which Seller shall use its good faith and commercially reasonable efforts to obtain without any obligation to expend any monies or undertake any obligations (other than requesting such consents) in connection with obtaining such access), Seller and its applicable Affiliates shall afford to Buyer and its Representatives (“Buyer’s Representatives”) reasonable access, during normal business hours, to the Subject Properties, all material Records and such other Records requested by Buyer that are in Seller’s or any of its Affiliates’ possession or control, at such time and to the extent reasonably necessary to conduct the title or environmental review for the purposes of Article V and Article VI. Buyer shall give Seller reasonable prior written notice before physically accessing any of the Subject Properties, and Seller or its designee shall have the right, but not the obligation, to accompany Buyer and Buyer’s Representatives at Seller’s sole cost whenever Buyer and/or Buyer’s Representatives physically access any Subject Property. All due diligence evaluation of the Subject Properties (including all investigations and inspections) conducted by Buyer or any Buyer’s Representative shall be conducted at Buyer’s sole cost, risk and expense and any conclusions made from any examination done by Buyer or any Buyer’s Representative shall result from Buyer’s own independent review and judgment.

(b) Subject to, and without limitation of, the terms set forth in this Section 4.1(b), from the Execution Date until the Environmental Defect Claim Date, Buyer’s inspection right with respect to the Environmental Condition of the Subject Properties shall be limited to conducting a Phase I ESA of the Subject Properties. Such Phase I ESA of the Subject Properties shall be limited to visual inspections of the Subject Properties and review of Records relating to the Subject Properties, and, in conducting such Phase I ESA, Buyer shall not operate any equipment or conduct any testing or sampling of soil, groundwater, air, or other substances or materials (including any testing or sampling for Hazardous Substances, Hydrocarbons or NORM). Notwithstanding anything in this Agreement to the contrary, Buyer shall not have access to, and shall not be permitted to, conduct any Phase I ESA of any Subject Property if neither Seller nor any of its Affiliates has the authority to grant access for such Phase I ESA or Seller’s request for such access has been denied; provided, however, that Seller shall use its commercially reasonable good faith efforts to obtain such access without the obligation to expend any monies or undertake any obligations (other than requesting such consents) in connection with obtaining such access. If Buyer determines in good faith that a Phase I ESA determines that sampling, testing, or other investigative activities (a “Phase II ESA”) are necessary in order for Buyer to prove the existence of or determine the Remediation Amount for, as applicable, an Environmental Defect that could reasonably be expected to exceed the Individual

13

Environmental Threshold as determined by Buyer in good faith and Buyer desires to perform any such Phase II ESA, Buyer shall, prior to the Environmental Defect Claim Date, (i) furnish Seller with a written description of the proposed scope of such Phase II ESA, including a description of the specific activities to be conducted, and a description of the approximate location and expected timing of such activities and (ii) obtain the prior written consent of Seller (such consent to be given at Seller’s sole discretion) to undertake such Phase II ESA. If the proposed Phase II ESA unreasonably interferes with the normal operations of the Subject Properties or otherwise may cause an undue risk of harm to the site, Seller may request an appropriate modification of the Phase II ESA. If Seller denies a good faith request by Buyer to undertake such Phase II ESA on any Subject Property pursuant to the foregoing provisions of this Section 4.1(b), Buyer shall have the right to exclude such Subject Property from the Conveyed Interests to be conveyed to Buyer at Closing in which event the Purchase Price shall be reduced by the Allocated Value of such Subject Property(ies) (and such Subject Property(ies) shall thereafter constitute Excluded Assets and Other Matters for all purposes of this Agreement). Any Phase I ESA and approved Phase II ESA shall be conducted by an Approved Buyer Environmental Consultant. Buyer shall obtain all permits necessary to conduct any approved Phase II ESA from any applicable Governmental Authorities prior to performing such approved Phase II ESA.

(c) Buyer shall coordinate its access rights, environmental property assessments, physical inspections and other due diligence evaluation of the Subject Properties with Seller to minimize any inconvenience to or unreasonable interruption of the conduct of business by Seller. To the extent provided to Buyer in advance, Buyer shall abide by Seller’s safety rules, regulations and operating policies while conducting its due diligence evaluation of the Subject Properties, including any access to, and environmental or other inspection or assessment of, the Subject Properties. Buyer hereby defends, indemnifies, and holds harmless Seller and each Seller Indemnified Party from and against any and all Liabilities arising out of, resulting from or relating to any field visit, environmental or other inspection or assessment, or other due diligence evaluation conducted by Buyer or any Buyer’s Representative with respect to the Subject Properties, EVEN IF SUCH LIABILITIES ARISE OUT OF OR RESULT FROM, IN WHOLE OR IN PART, THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OF, OR THE VIOLATION OF LAW BY, ANY SELLER INDEMNIFIED PARTY, EXCEPTING ONLY LIABILITIES TO THE EXTENT ACTUALLY RESULTING FROM THE ACTUAL FRAUD, GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SELLER OR ANY OTHER SELLER INDEMNIFIED PARTY.

(d) Buyer acknowledges that any entry into Seller’s offices or onto the Subject Properties shall be at Buyer’s sole risk, cost and expense, and, subject to the terms hereof and that none of the Seller Indemnified Parties shall be liable in any way for any injury, loss or damage arising out of such entry that may occur to Buyer or any of Buyer’s Representatives pursuant to this Agreement. Buyer hereby fully waives and releases any and all Liabilities against all of the Seller Indemnified Parties for any injury, death, loss or damage to any of Buyer’s Representatives or their property in connection with Buyer’s due diligence evaluation of the Subject Properties, EVEN IF SUCH LIABILITIES ARISE OUT OF OR RESULT FROM, IN WHOLE OR IN PART, THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OF, OR THE VIOLATION OF LAW BY, ANY SELLER INDEMNIFIED PARTY, EXCEPTING ONLY LIABILITIES ACTUALLY RESULTING FROM THE ACTUAL FRAUD, GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SELLER OR ANY OTHER SELLER INDEMNIFIED PARTY.

(e) If an Environmental Defect Notice is submitted by Buyer, Buyer agrees to contemporaneously provide Seller copies of all final environmental reports and test results prepared by Buyer and/or any of Buyer’s Representatives (including Buyer’s environmental consulting or engineering firm), which contain data collected or generated from Buyer’s and/or any of Buyer’s Representatives’ due diligence with respect to the Subject Properties that are the subject of the Environmental Defect Notice. Seller shall not be deemed by its or its representatives’ receipt of said documents to have made any representation or warranty, express, implied or statutory, as to the condition of the Subject Properties or the accuracy of said documents or the information contained therein.

14

(f) Upon completion of Buyer’s due diligence evaluation of the Subject Properties, Buyer shall at its sole cost and expense and without any cost or expense to Seller or any of its Affiliates (i) repair all damages done to any Subject Properties in connection with Buyer’s and/or any of Buyer’s Representatives’ due diligence evaluation (including any due diligence conducted by Buyer’s environmental consulting or engineering firm), (ii) if applicable, restore the Subject Properties to the approximate same condition as they were prior to commencement of any such due diligence evaluation and (iii) remove all equipment, tools and other property brought onto the Subject Properties in connection with such due diligence evaluation. Any material surface disturbance to the Subject Properties (including the leasehold associated therewith) resulting from such due diligence will be promptly corrected by Buyer at Buyer’s sole cost and expense.

(g) During all periods that Buyer and/or any of Buyer’s Representatives (including Buyer’s environmental consulting or engineering firm) are on the Subject Properties, Buyer shall maintain, at its sole cost and expense, customary policies of insurance in accordance with its ordinary course of business. Upon request by Seller, Buyer shall provide evidence of such insurance to Seller prior to entering any of the Subject Properties.

4.2 Confidentiality. Buyer acknowledges that, pursuant to its right of access to the Records or the Subject Properties, Buyer and/or Buyer’s Representatives (including Buyer’s environmental consulting or engineering firm) will become privy to confidential and other information of Seller and/or Seller’s Affiliates and Buyer shall ensure that such confidential information (a) shall not be used for any purpose other than in connection with the transactions contemplated by this Agreement and (b) shall be held confidential by Buyer and Buyer’s Representatives (including Buyer’s environmental consulting or engineering firm) in accordance with the terms of the Confidentiality Agreement. If the Closing should occur, the foregoing confidentiality restriction on Buyer shall terminate as of the Closing Date (except as to (i) such portion of the Conveyed Interests that are not conveyed to Buyer pursuant to the provisions of this Agreement, (ii) the Excluded Assets and Other Matters, and (iii) information related to Seller or Seller’s Affiliates (to the extent unrelated to the Conveyed Interests or the ownership or operation thereof)).

TITLE MATTERS; CASUALTY; TRANSFER RESTRICTIONS

5.1 General Disclaimer of Title Warranties and Representations. Except as and to the limited extent expressly represented otherwise in Sections 7.9, 7.14, 7.15, 7.17, 7.19(a), 7.20, 7.25, 7.26, 7.31 or 7.32, the certificate delivered by Seller pursuant to Section 12.3(l) (solely to the extent relating to Sections 7.9, 7.14, 7.15, 7.17, 7.19(a), 7.20, 7.25, 7.26, 7.31 or 7.32) or the Special Warranty set forth in the Assignments and Deeds and without limiting Buyer’s remedies for Title Defects set forth in this Article V, Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to Seller’s title to any of the Conveyed Interests, and Buyer hereby acknowledges and agrees that Buyer’s sole remedy for any defect of title, including any Title Defect, with respect to Seller’s title to any of the Conveyed Interests shall be (a) as set forth in Section 5.3, (b) pursuant to the Special Warranty set forth in the Assignments and Deeds in compliance with Section 5.2 below and as may otherwise be limited by this Agreement and (c) as set forth in Sections 7.9, 7.14, 7.15, 7.17, 7.19(a), 7.20, 7.25, 7.26, 7.31 or 7.32 and the certificate delivered by Seller pursuant to Section 12.3(l) (solely to the extent relating to Sections 7.9, 7.14, 7.15, 7.17, 7.19(a), 7.20, 7.25, 7.26, 7.31 or 7.32).

5.2 Special Warranty.

(a) Special Warranty of Defensible Title. If Closing occurs, then the Assignments and Deeds shall contain a special warranty of title whereby Seller shall warrant Defensible Title of Seller and its Affiliates to the applicable Conveyed Interests unto Buyer and its successors and assigns against every Person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under Seller or any of its Affiliates, but not otherwise, subject, however, to the Permitted Encumbrances (the “Special Warranty”); provided, however, that, except with respect to any Liability of Seller for any claim asserted in writing by Buyer to Seller in accordance with this Section 5.2 and the applicable Assignment or Deed, as applicable, before the expiration of the Survival Period for breach of the Special Warranty, the Special Warranty shall cease and terminate at the end of the Survival Period. The Special Warranty shall be subject to the further limitations and provisions of this Section 5.2.

(b) Recovery on Special Warranty.

(i) Buyer’s Assertion of Special Warranty Breaches. Prior to the expiration of the period of time commencing as of the Closing Date and ending at 5:00 P.M. (Central Time) on the fourth anniversary thereof (the “Survival Period”), Buyer shall be entitled to furnish Seller a Title Defect Notice meeting the requirements of Section 5.3(a) setting forth any and all matters which Buyer intends to

17

assert as a breach of the Special Warranty (collectively, the “Special Warranty Notices” and, individually, a “Special Warranty Notice”). Seller shall have a reasonable opportunity (not to exceed 90 days from delivery of a Special Warranty Notice by Buyer), but not the obligation, to cure any breach of the Special Warranty asserted by Buyer pursuant to this Section 5.2(b). Buyer shall reasonably cooperate (at Seller’s sole cost and expense) with any attempt by Seller to cure any such breach. For all purposes of this Agreement, Buyer shall be deemed to have waived, and Seller shall have no further Liability for, any breach of the Special Warranty that Buyer fails to assert by a Special Warranty Notice given to Seller before the expiration of the Survival Period.

(ii) Limitations on Special Warranty. Recovery by Buyer for any breach by Seller or any of its Affiliates of the Special Warranty shall be limited to an amount (without any interest accruing thereon) equal to (A), with respect to the Leases set forth on Exhibit A (limited to the Barnett Formation), the Wells set forth on Exhibit B (limited to the currently producing formation) and the Conveyed Interests set forth on Schedule I-2 (limited to the currently completed formation), the reduction to the Purchase Price to which Buyer would have been entitled had Buyer asserted the defect giving rise to such breach of the Special Warranty as a Title Defect prior to the Title Defect Claim Date pursuant to Section 5.3 and taking into account the last sentence of this Section 5.2(b)(ii), and (B), with respect to all other Conveyed Interests, the amount necessary to be paid to remove the applicable Encumbrance(s) from such Conveyed Interests (net to Seller’s and its Affiliates’ interest). With respect to those Conveyed Interests described in clause (A) above, in no event shall the recovery by Buyer exceed the Allocated Value of the affected Conveyed Interest (or portion thereof affected by such breach) and Buyer shall not be entitled to recover any amount for any breach of the Special Warranty to the extent that the same Title Defect is or has been taken into account for the reduction of the Purchase Price calculated pursuant to the other provisions of this Article V. The Individual Title Defect Threshold and the Title Defect Deductible shall not apply to any recovery for any breach by Seller or any of its Affiliates of the Special Warranty.

5.3 Notice of Title Defects; Defect Adjustments.

(a) Title Defect Notices. As a condition to Buyer asserting any claim with respect to any alleged Title Defect, Buyer must deliver claim notices to Seller meeting the requirements of this Section 5.3(a) (collectively, the “Title Defect Notices” and, individually, a “Title Defect Notice”) not later than the Title Defect Claim Date setting forth any matters which Buyer intends to assert as a Title Defect pursuant to this Section 5.3(a). For all purposes of this Agreement, the Assignments and Deeds and notwithstanding anything in this Agreement, the Assignments or the Deeds to the contrary, Buyer shall be deemed to have waived, and Seller shall have no Liability for, any Title Defect which Buyer fails to timely and properly assert as a Title Defect by a Title Defect Notice received by Seller before the Title Defect Claim Date, but subject to Section 5.1; provided, however, that, such waiver shall not apply to any Title Defect that is a breach of the Special Warranty. To be effective, each Title Defect Notice shall be in writing, and shall include (i) a description of the alleged Title Defect and the individual Conveyed Interest affected by the alleged Title Defect (each such Lease, Well or Conveyed Interest set forth on Schedule I-2, a “Title Defect Property”), (ii) the Allocated Value of each Title Defect Property, (iii) supporting documents (which may include landman’s reports and title run sheets) reasonably necessary for Seller to identify the alleged Title Defect with respect to each Title Defect Property, and (iv) with respect to each Title Defect Property (any and all of which supporting documents may be furnished via access to a web link or ftp site (in lieu of other means of delivery)), the amount by which Buyer reasonably believes the Allocated Value of the Title Defect Property is reduced by such alleged Title Defect and the computations upon which Buyer’s belief is based, in each case, in accordance with Section 5.3(g). Notwithstanding anything to the contrary in this Agreement, the failure of any Title Defect Notice to include any of the information or documentation identified or described in Section 5.3(a)(i) through Section 5.3(a)(iv) above shall not render such Title Defect Notice void or ineffective if such Title Defect Notice otherwise materially complies with the requirements set forth in this Section 5.3(a) and provides Seller with sufficient information to evaluate the

18

alleged Title Defect. Notwithstanding anything in this Agreement to the contrary, and for the avoidance of doubt, Buyer shall not have the right to assert any Title Defect with respect to any Conveyed Interests other than (A) the Leases set forth on Exhibit A (limited to the Barnett Formation), (B) the Wells set forth on Exhibit B (limited to the currently producing formation for each such Well) or (C) the Conveyed Interests set forth on Schedule I-2 (limited to the currently completed formation for each such Conveyed Interest). To give Seller an opportunity to commence reviewing and curing Title Defects, Buyer agrees to use commercially reasonable efforts (without the obligation to expend any monies or undertake any obligations) to give Seller, at least once every 2 calendar weeks prior to the Title Defect Claim Date, written notice of all alleged Title Defects (as well as any claims that would be claims under the Special Warranty) discovered by Buyer during the preceding 2 calendar weeks, which notice may be preliminary in nature and amended, modified, supplemented, replaced and/or withdrawn (in-whole or in-part) at any time prior to the Title Defect Claim Date; provided that the failure of Buyer to provide preliminary notice of any Title Defects shall not be deemed to waive, limit, restrict or otherwise prejudice Buyer’s right to assert a Title Defect on or before the Title Defect Claim Date in accordance with this Section 5.3(a). Buyer shall also promptly upon discovery, furnish Seller with written notice of any Title Benefit (1) which is actually discovered by Buyer prior to the Title Defect Claim Date, including to the extent Buyer is notified thereof by any of Buyer’s or any of its Affiliates’ employees, title attorneys, landmen or other title examiners while conducting Buyer’s due diligence with respect to the Conveyed Interests prior to the Title Defect Claim Date and (2) as to which Buyer believes in good faith actually exists of record.

(b) Title Benefit Notices. Seller shall have the right, but not the obligation, to deliver to Buyer on or before the Title Defect Claim Date with respect to each Title Benefit a notice (a “Title Benefit Notice”) including (i) a description of the alleged Title Benefit and the individual Lease or Well affected by such alleged Title Benefit (each such Conveyed Interest, a “Title Benefit Property”), (ii) with respect to each Title Benefit Property, the amount by which Seller reasonably believes the Allocated Value of such Title Benefit Property is increased by such alleged Title Benefit, (iii) the computations upon which Seller’s belief is based in accordance with Section 5.3(h) and (iv) supporting documents reasonably necessary for Buyer to identify such Title Benefit. Other than any Title Benefits which Buyer reports to Seller pursuant to Section 5.3(a), Seller shall be deemed to have waived any Title Benefit which Seller fails to assert as a Title Benefit in a Title Benefit Notice delivered to Buyer on or before the Title Defect Claim Date.

(c) Seller’s Right to Cure. Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure any alleged Title Defects at any time prior to 5:00 p.m. Central Time on the date that is 60 days after the Closing Date (the “Title Defect Cure Deadline”); provided, that Seller shall only be permitted to exercise such right to elect to cure (or attempt to cure) any such Title Defect during the period between the Closing Date and the Title Defect Cure Deadline if such Title Defect is reasonably capable of being cured by Seller prior to the Title Defect Cure Deadline (as reasonably determined by Seller in good faith). During the period of time from Closing to the expiration of the Title Defect Cure Deadline, Buyer agrees to afford Seller and its officers, employees and other authorized representatives reasonable access, during normal business hours, to the Subject Properties and all Records in Buyer’s or any of its Affiliates’ possession in order to facilitate Seller’s attempt to cure any such Title Defects; provided that the indemnity provisions in Sections 4.1(c) and 4.1(d) shall apply to Seller mutatis mutandis. An election by Seller to attempt to cure a Title Defect shall be without prejudice to its other rights under this Section 5.3 and shall not constitute an admission against interest or a waiver of Seller’s right to dispute the existence, nature or value of, or cost to cure, the alleged Title Defect. Seller shall provide Buyer written notice of Seller’s good faith election to cure any Title Defect no later than 10 Business Days after the Title Defect Claim Date (“Cure Notice”), and the failure to provide notice by such date shall be deemed an election not to cure (or to attempt to cure) by Seller. Such Cure Notice shall identify each individual Title Defect to be cured by Seller. In the event the Seller fails to deliver a Cure Notice within 10 Business Days after the Title Defect Claim Date or fails to deliver a Cure Notice electing to cure a Title Defect identified in the Title Defect Notice, as applicable, Seller shall waive the right to cure such Title Defects.

19

(d) Remedies for Title Defects. Subject to Seller’s continuing right to (x) dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto as described in Section 5.3(j) and (y) cure (or attempt to cure) any Title Defect pursuant to, and in accordance with, Section 5.3(c), and subject to the limitations set forth in Section 5.3(i) and the rights of the Parties pursuant to Section 14.1(f), in the event that Seller has not cured a Title Defect that has been timely and properly asserted by Buyer in accordance with Section 5.3(a) by the expiration of the Title Defect Cure Deadline, and such Title Defect has not been expressly waived by Buyer, Seller shall, at its sole option, elect to:

(i) reduce the Purchase Price or Final Price, as applicable, by the Title Defect Amount determined pursuant to Section 5.3(g) or Section 5.3(j); or

(ii) if the Title Defect Amount of any Title Defect applicable to a Title Defect Property equals or exceeds fifty percent (50%) of the Allocated Value of such Title Defect Property, unless Buyer otherwise elects to waive the applicable Title Defect prior to the Closing, Seller may retain such Title Defect Property and reduce the Purchase Price by an amount equal to the Allocated Value (or portion thereof allocable thereto) of such Title Defect Property, in which event the Parties shall, subject to Article X and Article XI, proceed to the Closing, and such Title Defect Property shall be retained by Seller (and shall, for purposes of clarity, thereafter be deemed to constitute an Excluded Asset and Other Matters for all purposes of this Agreement). For purposes of clarity, (1) if the Title Defect Amount does not exceed 50% of the Allocated Value of such Title Defect Property, then a downward Purchase Price adjustment shall be made in accordance with Section 5.3(d)(i) above and (2) notwithstanding anything to the contrary herein, Seller may only elect the remedy set forth in clause (ii) above prior to the Closing Date.

In the event that, as of the Closing Date, there are Title Defects with respect to which (A) Seller has not elected to cure pursuant to the Cure Notice and (B) Seller has not notified Buyer that it disputes the Title Defect or the Title Defect Amount, the Purchase Price shall be reduced at Closing by the aggregate Title Defect Amount of such Title Defects as determined pursuant to Section 5.3(g) less any Title Benefits with respect to which Buyer has not disputed (or deemed to have conceded pursuant to Section 5.3(e)) the Title Benefit or Title Benefit Amount, subject to the limitations in Section 5.3(e) and Section 5.3(i). If Seller and Buyer are unable to agree on any Title Defect, Title Benefit, Title Defect Amount or Title Benefit Amount at the Closing, Buyer’s good faith determination with respect to such Title Defect, Title Benefit, Title Defect Amount or Title Benefit Amount shall be utilized for purposes of determining the Defect Escrow Amount at Closing.

(e) Remedies for Title Benefits. With respect to each Title Benefit Property reported under Sections 5.3(a) or 5.3(b), Buyer shall notify Seller in writing on or before the date that is five Business Days prior to the Scheduled Closing Date whether Buyer (i) concedes the Title Benefit asserted therein or (ii) disputes such Title Benefit and/or the Title Benefit Amount thereof, in which case such Title Benefit shall be deemed to be a Title Dispute and the provisions of Section 5.3(j) shall apply. If Buyer fails to notify Seller by such date with respect to such a Title Benefit, Buyer shall be deemed to have conceded such Title Benefit. Title Benefits Amounts shall in no event result in an increase to the Purchase Price, and shall only be applied in the manner set forth in Section 5.3(i).

(f) Exclusive Remedy. Except for Fraud, Buyer’s rights under the Special Warranty, and Buyer’s right to terminate this Agreement pursuant to Section 14.1(f), and without limitation of any of Seller’s indemnity obligations hereunder with respect to Sections 7.9, 7.14, 7.15, 7.17, 7.19(a), 7.20, 7.25, 7.26, 7.31 or 7.32, and Sections 10.4 and 11.4, Section 5.3(d) shall be the exclusive right and remedy of Buyer with respect to Seller’s failure to have Defensible Title with respect to any Lease or Well, or any other title matter with respect to any Subject Property, and Buyer hereby waives any and all other rights or remedies with respect thereto. For the avoidance of doubt, the foregoing shall not limit each Party’s rights and obligations under Section 5.5.

20

(g) Title Defect Amount. The amount by which the Allocated Value of a Title Defect Property is reduced as a result of the existence of a Title Defect shall be the “Title Defect Amount” for such Title Defect Property and shall be determined in accordance with the following terms and conditions (without duplication):

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

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

(iii) if the Title Defect represents a decrease of (A) Seller’s Net Revenue Interest for a Title Defect Property such that Seller’s Net Revenue Interest for such Title Defect Property is less than (B) the Net Revenue Interest set forth for such Title Defect Property on Exhibit A, Exhibit B or Schedule I-2, then the Title Defect Amount shall be the product of the Allocated Value of such Title Defect Property multiplied by a fraction, the numerator of which is the Net Revenue Interest decrease and the denominator of which is the Net Revenue Interest set forth for such Title Defect Property on Exhibit A, Exhibit B or Schedule I-2, as applicable;

(iv) if the Title Defect represents an increase of (A) Seller’s Working Interest for a Title Defect Property such that Seller’s Working Interest for such Title Defect Property is in excess of (B) the Working Interest set forth for such Title Defect Property on Exhibit A, Exhibit B or Schedule I-2, as applicable, without a proportionate increase of Seller’s Net Revenue Interest for such Title Defect Property, then the Title Defect Amount shall be the product of the Allocated Value of such Title Defect Property multiplied by a fraction, the numerator of which is the Working Interest increase and the denominator of which is the Working Interest set forth for such Title Defect Property on Exhibit A, Exhibit B or Schedule I-2, as applicable;

(v) if the Title Defect represents a discrepancy where (A) the actual Net Acres for such Title Defect Property is less than (B) the Net Acres set forth on Exhibit A for such Title Defect Property, then the Title Defect Amount shall be the product obtained by multiplying such Net Acre decrease by the Allocated Value (on a per Net Acre dollar amount basis) for such Title Defect Property;

(vi) if the Title Defect represents an obligation or Encumbrance upon or other defect in title to the Title Defect Property of a type not described above (which shall include any Title Defect which causes Seller not to have Defensible Title in and to a Title Defect Property with respect to any portion, but not the entirety, of such Title Defect Property), then the Title Defect Amount shall be determined by taking into account the Allocated Value of the affected Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the affected Title Defect Property, the other applicable methodologies set forth in this Section 5.3(g), and if any, the values placed upon the affected Title Defect Property by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation;

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

21

(viii) notwithstanding anything in this Article V to the contrary, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Value of such Title Defect Property (or portion thereof affected by such Title Defects).

If an individual Title Defect affects more than one Title Defect Property, the Title Defect Amounts for each such Title Defect Property shall be aggregated for purposes of determining whether the Title Defect Amounts of any such individual Title Defect in the aggregate exceed the Individual Title Defect Threshold. Further, if a Lease set forth on Exhibit A has the same Lease Number as one or more other Leases set forth on Exhibit A, for purposes of Article V, the Allocated Value of such Lease shall be the aggregate of the amounts set forth under the column titled “Allocated Values” for each such Lease with the same Lease Number.

(h) Title Benefit Amount. The Title Benefit Amount resulting from a Title Benefit shall be determined in accordance with the following methodology, terms and conditions (without duplication):

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

(ii) if the Title Benefit represents an increase of (A) Seller’s Net Revenue Interest for a Title Benefit Property by more than (B) the Net Revenue Interest set forth for such Title Benefit Property on Exhibit A, Exhibit B or Schedule I-2, then the Title Benefit Amount shall be the product of the Allocated Value of such Title Benefit Property multiplied by a fraction, the numerator of which is the Net Revenue Interest increase and the denominator of which is the Net Revenue Interest set forth for such Title Benefit Property on Exhibit A, Exhibit B or Schedule I-2, as applicable;

(iii) if the Title Benefit represents a discrepancy where (A) the actual Net Acres for such Title Benefit Property is greater than (B) the Net Acres set forth on Exhibit A for such Title Benefit Property, then the Title Benefit Amount shall be the product obtained by multiplying such Net Acre increase by the Allocated Value (on a per Net Acre dollar amount basis) for such Title Benefit Property; and

(iv) if the Title Benefit is of a type not described above (including the circumstances where a Title Benefit affects a portion, but not the entirety of any Lease), then the Title Benefit Amounts shall be determined by taking into account the Allocated Value of the Title Benefit Property, the portion of such Title Benefit Property affected by such Title Benefit, the legal effect of the Title Benefit, the potential economic effect of the Title Benefit over the life of such Title Benefit Property, the other applicable methodologies set forth in this Section 5.3(h), if any, the values placed upon the Title Benefit by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation.

(i) Title Defect Threshold and Deductible. (i) Subject to the last sentence of Section 5.3(g), in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller hereunder for any individual Title Defect for which the Title Defect Amount for a Title Defect Property does not exceed $[***] (the “Individual Title Defect Threshold”); and (ii) in no event shall there be any adjustment to the Purchase Price or other remedies provided by Seller hereunder for any Title Defect for which the Title Defect Amount for a Title Defect Property exceeds the Individual Title Defect Threshold unless (A) the amount of the sum of (x) the aggregate Title Defect Amounts of all such Title Defect Properties where the Individual Title Defect Threshold is exceeded (but excluding any Title Defect Amounts attributable to Title Defects to the extent cured by Seller on or prior to the Title Defect Cure Deadline) less (y) the aggregate Title Benefit Amount of all Title Benefits, exceeds (B) an amount equal to [***] percent ([***]%) of the unadjusted Purchase Price, or, in the event Seller does not acquire the Other Working Interest Owner Interests prior to Closing Date in accordance with Section 9.14, an amount equal

22

to [***]percent ([***]%) of the unadjusted Purchase Price less the Allocated Other Working Interest Owner Amount (the “Title Defect Deductible”), after which point Buyer shall be entitled to adjustments to the Purchase Price or other applicable remedies available hereunder, but only to the extent that the amount by which the sum of clause (A) above exceeds the Title Defect Deductible.

(j) Title Dispute Resolution. Seller and Buyer shall attempt to agree on matters regarding (i) all Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts, and (ii) the adequacy of any curative materials provided by Seller to cure any alleged Title Defect (any disagreements between the Parties as to clauses (i) and/or (ii), collectively “Title Disputes”) prior to the Title Defect Cure Deadline. Subject to, and without limitation of, Section 10.4 and Section 11.4 (and the Parties respective rights and remedies with respect thereto), if Seller and Buyer are unable to agree by the Title Defect Cure Deadline, the Title Disputes shall be exclusively and finally resolved pursuant to this Section 5.3(j). There shall be a single arbitrator, who shall be a title attorney with at least 15 years’ experience reviewing oil and gas titles involving properties in the State of Texas, as selected by the mutual agreement of Buyer and Seller within 15 days after the Dispute Date (the “Title Arbitrator”). If the Parties do not mutually agree upon the Title Arbitrator in accordance with this Section 5.3(j), the Houston, Texas office of the AAA shall appoint the Title Arbitrator under such conditions as the AAA in its sole discretion deems necessary or advisable. The place of arbitration shall be Houston, Texas and the arbitration shall be conducted in accordance with the AAA Rules, to the extent such rules do not conflict with the terms of this Section 5.3(j). Each of Buyer and Seller shall submit to the Title Arbitrator, with a simultaneous copy to the other Party, its proposed resolution of the applicable Title Dispute no later than 10 Business Days after the appointment of the Title Arbitrator pursuant to this Section 5.3(j). The proposed resolution of the applicable Title Dispute shall include the best offer of the submitting Party in a single monetary amount that such Party is willing to pay or accept (as applicable) to settle the applicable Title Dispute. The Title Arbitrator’s determination shall be made within 20 days after the end of such ten Business Day period after the submission of the Title Disputes and shall be final and binding upon both Parties, without right of appeal and shall be enforceable against the Parties in a court of competent jurisdiction. Once appointed, the Title Arbitrator shall have no ex parte communication with either Party related to Title Disputes. In making his determination, the Title Arbitrator shall make a determination of the Title Disputes submitted based solely on the single written submission of Seller and Buyer (and without any additional or supplemental submittals by any Party, except to the extent the Title Arbitrator requests additional information from either Party), shall be bound by the rules set forth in Section 5.3(g) and Section 5.3(h) and, subject to the foregoing, may consider such other matters as, in the opinion of the Title Arbitrator, are necessary to make a proper determination. The Title Arbitrator, however, may not award Buyer a greater Title Defect Amount than the Title Defect Amount claimed by Buyer in its applicable Title Defect Notice or a greater Title Benefit Amount than that claimed by Seller in its applicable Title Benefit Notice. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific Title Disputes submitted by either Party, and may not award damages, interest or penalties to either Party with respect to any matter except as otherwise provided in the following sentence. The costs of the Title Arbitrator (and the AAA, if applicable) and the reasonable legal costs and expenses incurred by the Parties in connection with the arbitration shall be borne pro rata between the Parties with each Party being responsible for such costs and expenses to the extent the Title Arbitrator has not selected such Party’s position on an aggregate dollar basis with respect to all amounts submitted for resolution by the Title Arbitrator. To the extent the award of the Title Arbitrator with respect to any Title Defect Amount or Title Benefit Amount is not taken into account as an adjustment to the Purchase Price in the Final Settlement Statement, then within 10 days after the date the Title Arbitrator delivers written notice to Buyer and Seller of his award with respect to a Title Dispute, and, subject to Section 5.3(i), the amount, if any, so awarded to a Party shall first be satisfied out of the balance of the Defect Escrow Amount remaining after the application of Section 3.6(b) and, then, if applicable, the owing Party shall pay to the owed Party any outstanding awarded amount.

23

(k) Walk-Right Title Dispute Resolution. In the event a Party notifies the other Party of the intention to terminate this Agreement in accordance with Section 14.1(f), Seller or Buyer may, prior to giving effect to Section 14.1(f), as applicable, elect to submit all Title Disputes to the Title Arbitrator in accordance with the procedures set forth in Section 5.3(j); provided, that notwithstanding anything to the contrary in Section 5.3(j), such proceeding shall be solely to determine whether the aggregate adjustments pursuant to Section 10.4 or Section 11.4, as applicable, in respect of any Title Disputes would, when taken together with all other adjustments pursuant to Section 10.4 or Section 11.4, trigger the termination right under Section 14.1(f). For the avoidance of doubt, if Seller or Buyer elect to submit to the Title Arbitrator in accordance with this Section 5.3(k), no Party may terminate this Agreement pursuant to Section 14.1(f) until final resolution of such arbitration unless the termination right under Section 14.1(f) would otherwise apply solely by virtue of any undisputed Title Defect Amounts, together the other aggregate adjustments pursuant to Section 10.4 or Section 11.4, as applicable.

5.4 Casualty or Condemnation Loss.

(a) Notwithstanding anything in this Agreement to the contrary but without limitation of Seller’s indemnity obligations hereunder, from and after the Effective Time, if Closing occurs, Buyer shall assume all risk of loss with respect to production of Hydrocarbons through normal depletion (including watering out of any well, collapsed casing or sand infiltration of any well) and the depreciation of Conveyed Interests due to ordinary wear and tear, in each case, with respect to the Conveyed Interests, and Buyer shall not assert such matters as Casualty Losses or Title Defects hereunder.

(b) If, after the Execution Date but prior to the Closing Date, any portion of the Conveyed Interests is damaged or destroyed by fire or other casualty or is taken in condemnation or under right of eminent domain (each, a “Casualty Loss”), then Seller shall (i) in the case of any material Casualty Loss, promptly notify Buyer in writing following the occurrence of such Casualty Loss, which notice shall include reasonable detail of the nature of such Casualty Loss and (ii) if the Closing occurs, at the Closing, (A) pay to Buyer all sums received by Seller or any of its Affiliates from any Person with respect to such Casualty Loss and (B) assign, transfer and set over to Buyer, or subrogate Buyer to, all of Seller’s and its Affiliates’ respective right, title and interest (if any) in and to any insurance claims, unpaid awards and other rights and remedies against or with respect to any Person arising out of, or in connection with, such Casualty Loss. Neither Seller nor any of its Affiliates shall compromise, settle or adjust any amounts payable by reason of, or in connection with, any material Casualty Loss without the prior written consent of Buyer.

(c) If, after the Execution Date, but prior to the Closing Date, all or any portion of any of the Conveyed Interests is taken in condemnation or under right of eminent domain by any Governmental Authority, the affected Conveyed Interests (or portions thereof) shall be excluded from the Conveyed Interests to be conveyed to Buyer at the Closing to the extent of the interest affected by such condemnation or right of eminent domain and the Purchase Price will be reduced by the Allocated Value of such affected Conveyed Interests (or portion thereof).

(d) If in the event that the Parties have failed to agree in good faith by Closing on the Casualty Loss amount, such Casualty Loss amount will be determined by a single independent arbitrator with relevant experience in accordance with the procedures set forth in Section 5.3(j) (including with respect to the selection of such arbitrator), mutatis mutandis.

5.5 Preferential Purchase Rights and Consents to Assign.

(a) With respect to each Preferential Purchase Right set forth on Schedule 7.9, not later than 10 days after the Execution Date, except for those Preferential Purchase Rights set forth on

24

Schedule 5.5, which shall be sent within 80 days after the Execution Date (and, with respect to each Preferential Purchase Right that is not set forth on Schedule 7.9 but is discovered by either Party after the Execution Date and before the Closing Date, not later than 10 days after the discovery thereof (or, if discovered by Buyer, no later than 10 days after Buyer notifies Seller in writing of such Preferential Purchase Rights)), Seller shall (x) send to the holder of each such Preferential Purchase Right a written notice in material compliance with the underlying agreement, Contract, Lease, Permit and/or Law applicable to or otherwise giving rise to such Preferential Purchase Right, requesting a waiver of such Preferential Purchase Right and (y) provide Buyer with a true and complete copy of each such notice promptly after Seller’s delivery thereof in accordance with this Section 5.5(a). In the event any delay in Closing results in an additional notice requirement or exercise period under any applicable Preferential Purchase Right, Seller shall be permitted to provide such notice or comply with such exercise period thereunder and shall promptly notify Buyer in writing if it takes any such action. Seller shall use commercially reasonable efforts to obtain waivers of all Preferential Purchase Rights prior to the Scheduled Closing Date; provided, however, Seller shall not be obligated to expend any monies or undertake any obligations (other than requesting such waivers) in connection with such obtaining waivers of such Preferential Purchase Rights. Seller covenants and agrees that it shall promptly provide written notice to Buyer after becoming aware of any actual or threatened dispute, disagreement or Proceeding affecting or with respect to any Preferential Purchase Right affecting or relating to the transactions contemplated by this Agreement.

(i) If, prior to Closing, any holder of a Preferential Purchase Right notifies Seller that it intends to consummate the purchase of the Conveyed Interests to which its Preferential Purchase Right applies, then (w) the Conveyed Interest(s) (or portion(s) thereof) that are subject to such Preferential Purchase Right shall be excluded from the Conveyed Interests to be assigned to Buyer at Closing (but only to the extent of the portion(s) of such Conveyed Interest(s) affected by such Preferential Purchase Right), (x) such Conveyed Interest(s) (or portion(s) thereof) shall, subject to the remaining provisions of this Section 5.5(a)(i), thereafter constitute Excluded Assets and Other Matters, (y) the Purchase Price shall be reduced at Closing by the Allocated Value of such Conveyed Interest (or portion thereof) so excluded. Seller shall be entitled to all proceeds paid by any Person exercising a Preferential Purchase Right prior to Closing and (z) notwithstanding the foregoing, Seller shall continue to conduct operations in the ordinary course during the period beginning on the Closing Date and ending 180 days thereafter with respect to the applicable Conveyed Interests subject to such Preferential Purchase Rights. If (A) on or before 180 days following the Closing Date, such holder of such Preferential Purchase Right fails to consummate the purchase of the Conveyed Interest (or portion thereof) covered by such Preferential Purchase Right, or (B) such Preferential Purchase Right holder waives in writing such Preferential Purchase Right at any time during the 180-day period following the Closing Date, and, in each case, there is no pending or threatened dispute, disagreement or Proceeding with respect to any matter related to any such Preferential Purchase Right, then (1) Seller shall promptly notify Buyer in writing thereof, (2) Buyer shall purchase, on or before the date that is ten Business Days following receipt of such notice, such Conveyed Interest(s) (or portion(s) thereof) that were so excluded from the Conveyed Interests assigned to Buyer at Closing, under the terms of this Agreement and for a price equal to the amount by which the Purchase Price was reduced at Closing with respect to such excluded Conveyed Interest(s) (or portion(s) thereof) (as such amount is appropriately adjusted in accordance with the other terms of this Agreement) and (3) Seller shall assign to Buyer such Conveyed Interest(s) (or portion(s) thereof) pursuant to an instrument in substantially the same form as the Assignment or Deed, as applicable, and such Conveyed Interest(s) (or portion(s) thereof) shall cease to be Excluded Assets and Other Matters; provided, however, that notwithstanding anything to the contrary herein, Buyer shall have the right to elect (in its sole discretion) not to purchase or acquire any Conveyed Interests (or portion(s) thereof) that are subject to or affected by a Preferential Purchase Right that is described in subclause (A) of this Section 5.5(a)(i) if there is an unresolved dispute, disagreement or Proceeding with respect to such Preferential Purchase Right on the date that is 180 days following the Closing Date.

25

(ii) If (A) a Preferential Purchase Right has been waived in writing by the applicable holder thereof prior to Closing or (B) as of the Closing, the time period for the exercise of any Preferential Purchase Right expires without being exercised or waived in writing by the holder thereof and, in each case, there is no pending or threatened dispute, disagreement or Proceeding with respect to any matter related to any such Preferential Purchase Right, then, the Conveyed Interests that are subject to such Preferential Purchase Rights shall be sold to Buyer at Closing pursuant to the provisions of this Agreement.

(iii) If, as of the Closing, (A) the time period for exercising any Preferential Purchase Right has not expired without exercise prior to Closing (and such Preferential Purchase Right has not been waived in writing by the holder thereof) or (B) there is any pending or threatened dispute, disagreement or Proceeding with respect to any matter related to any Preferential Purchase Right, then (unless Buyer expressly agrees otherwise in writing) (x) the Conveyed Interest(s) (or portion(s) thereof) subject to any such Preferential Purchase Right shall be excluded from the Conveyed Interests assigned to Buyer at Closing, (y) such Conveyed Interest(s) (or portion(s) thereof) shall, subject to the remaining provisions of this Section 5.5(a)(iii), thereafter constitute Excluded Assets and Other Matters, and (z) the Purchase Price shall be adjusted downward at Closing by the Allocated Value attributable to the affected Conveyed Interests. If, prior to the date that is 180 days following the Closing, such Preferential Purchase Right expires without exercise by the holder thereof (or is otherwise waived in writing by the holder thereof) and, as of such date, there is no pending or threatened dispute, disagreement or Proceeding with respect to any matter related to such Preferential Purchase Right, then (1) Seller shall promptly notify Buyer in writing thereof, (2) Buyer shall purchase, on or before the date that is ten Business Days following receipt of such notice, such Conveyed Interest(s) (or portion(s) thereof) that were so excluded from the Conveyed Interests assigned to Buyer at Closing, under the terms of this Agreement and for a price equal to the amount by which the Purchase Price was reduced at Closing with respect to such excluded Conveyed Interest(s) (or portion(s) thereof) (as such amount is appropriately adjusted in accordance with the other terms of this Agreement) and (3) Seller shall assign to Buyer such Conveyed Interest(s) (or portion(s) thereof) pursuant to an instrument in substantially the same form as the Assignment and such Conveyed Interest(s) (or portion(s) thereof) shall cease to be Excluded Assets and Other Matters.

(b) With respect to each Consent set forth on Schedule 7.4 (other than, for purposes of clarity, the Post-Closing Consents or FCC Consents), Seller, not later than 10 days after the Execution Date (and, other than Post-Closing Consents or FCC Consents, with respect to each such Consent that is required to be set forth on Schedule 7.4 but is not set forth on Schedule 7.4 and is discovered by either Party after the Execution Date and before the Closing Date), not later than 10 days after the discovery thereof (or, if discovered by Buyer, no later than 10 days after Buyer notifies Seller in writing of such Consent), shall (i) deliver to the holder of each such Consent a written notice in material compliance with the applicable underlying agreement, Contract, Lease, Permits or Law applicable to or otherwise giving rise to such Consent seeking such holder’s consent to the transactions contemplated hereby (or waiver thereof) and (ii) provide Buyer with a true and complete copy of each such notice promptly after Seller’s delivery thereof in accordance with this Section 5.5(b). Seller covenants and agrees that it shall promptly provide written notice to Buyer upon becoming aware of any actual or threatened dispute, disagreement or Proceeding affecting or related to any Consent.

(i) If, as of the Closing, (A) Seller fails to obtain any Required Consent (or waiver in writing by the holder thereof) set forth in Schedule 7.4 or any Required Consent (or waiver in writing by the holder thereof) that is required to be set forth on Schedule 7.4 but is not set forth on Schedule 7.4 and is discovered by either Party after the Execution Date and before the Closing Date or (B) there is any pending or threatened dispute, disagreement or Proceeding with respect to any matter related to any Required Consent, then, in each case (unless Buyer, in its sole discretion, elects to expressly waive such consent in writing), (1) the Conveyed Interest(s) (or portion(s) thereof) that are subject to any such Required Consent shall be excluded from the Conveyed Interests to be assigned to Buyer at Closing, (2) such

26

Conveyed Interest(s) (or portion(s) thereof) shall, subject to the remaining provisions of this Section 5.5(b)(i), thereafter constitute Excluded Assets and Other Matters and (3) the Purchase Price shall be reduced at Closing by the Allocated Value of such Conveyed Interest(s) (or portion(s) thereof). In the event that (x) any such Required Consent (or a waiver in writing by the holder thereof) is obtained prior to the date that is 180 days following Closing and (y) as of such date, there is no pending or threatened dispute, disagreement or Proceeding with respect to any matter related to such Required Consent, then, (a) Seller shall deliver written notice thereof to Buyer and (b) on the date that is ten Business Days after such notice is delivered to Buyer (i) Buyer shall purchase the Conveyed Interest(s) (or portion(s) thereof) that were so excluded as a result of such un-obtained and/or disputed Required Consent and pay to Seller the amount by which the Purchase Price was reduced at Closing with respect to such Conveyed Interest(s) (or portion(s) thereof) (as such amount is appropriately adjusted in accordance with the other terms of this Agreement) and (ii) Seller shall assign to Buyer such Conveyed Interest(s) (or portion(s) thereof) pursuant to an instrument in substantially the same form as the Assignment and such Conveyed Interest(s) (or portion(s) thereof) shall cease to be Excluded Assets and Other Matters. Notwithstanding the foregoing sentence, Buyer shall have the right, but not the obligation, to waive any Required Consent (in Buyer’s sole discretion) by delivering written notice to Seller. If such a waiver is delivered to Seller and, at such time, the Closing has occurred, then Seller shall promptly assign to Buyer the Conveyed Interest(s) subject to any such waived Required Consent, and Buyer shall pay to Seller an amount equal to the amount by which the Purchase Price was reduced at Closing with respect to such Conveyed Interest(s) (as such amount is appropriately adjusted in accordance with the other terms of this Agreement), and Buyer shall thereafter have no claim against Seller in connection with Seller’s failure to obtain such Required Consent (or a waiver in writing by the holder thereof) and shall release and indemnify the Seller Indemnified Parties from any Liability to the extent arising from the failure to obtain such Required Consent (or a waiver in writing by the holder thereof).

(ii) If, as of the Closing, (A) Seller fails to obtain any Medium Consent (or waiver in writing by the holder thereof) set forth in Schedule 7.4 or any Medium Consent (or waiver in writing by the holder thereof) that is required to be set forth on Schedule 7.4 but is not set forth on Schedule 7.4 and is discovered by either Party after the Execution Date and before the Closing Date or (B) there is any pending or threatened dispute, disagreement or Proceeding with respect to any matter related to any Medium Consent, then, in each case (unless Buyer, in its sole discretion, elects to expressly waive such consent in writing), (1) the Conveyed Interest(s) (or portion(s) thereof) that are subject to any such Medium Consent shall be excluded from the Conveyed Interests to be assigned to Buyer at Closing, (2) such Conveyed Interest(s) (or portion(s) thereof) shall, subject to the remaining provisions of this Section 5.5(b)(ii), thereafter constitute Excluded Assets and Other Matters and (3) the Purchase Price shall be reduced at Closing by the Allocated Value of such Conveyed Interest(s) (or portion(s) thereof). If, as of the date that is 180 days following the Closing, (x) any such Medium Consent (or a waiver in writing by the holder thereof) is obtained or (y) as of such date, any such Medium Consent is not obtained (or a waiver in writing by the holder thereof is not obtained) and (A) there is no pending or threatened dispute, disagreement or Proceeding with respect to any matter related to such Medium Consent and (B) such Medium Consent is not denied in writing by the holder thereof, then, (a) Seller shall deliver written notice thereof to Buyer and (b) on the date that is ten Business Days after such notice is delivered to Buyer (i) Buyer shall purchase the Conveyed Interest(s) (or portion(s) thereof) that were so excluded as a result of such previously un-obtained and/or disputed Medium Consent and pay to Seller the amount by which the Purchase Price was reduced at Closing with respect to such Conveyed Interest(s) (or portion(s) thereof) (as such amount is appropriately adjusted in accordance with the other terms of this Agreement) and (ii) Seller shall assign to Buyer such Conveyed Interest(s) (or portion(s) thereof) pursuant to an instrument in substantially the same form as the Assignment or Deed, as applicable, and such Conveyed Interest(s) (or portion(s) thereof) shall cease to be Excluded Assets and Other Matters. Notwithstanding the foregoing sentence, Buyer shall have the right, but not the obligation, to waive any Medium Consent (in Buyer’s sole discretion) by delivering written notice to Seller. If such a waiver is delivered to Seller and, at such time, the Closing has occurred, then Seller shall promptly assign to Buyer the Conveyed Interest(s) subject to any such

27

waived Medium Consent, and Buyer shall pay to Seller an amount equal to the amount by which the Purchase Price was reduced at Closing with respect to such Conveyed Interest(s) (as such amount is appropriately adjusted in accordance with the other terms of this Agreement), and Buyer shall thereafter have no claim against Seller in connection with Seller’s failure to obtain such Medium Consent (or a waiver in writing by the holder thereof) and shall release and indemnify the Seller Indemnified Parties from any Liability to the extent arising from the failure to obtain such Medium Consent (or a waiver in writing by the holder thereof).

(iii) Prior to Closing, other than Post-Closing Consents (and subject to and except as otherwise provided in Section 9.3), and, with respect to any Medium Consents or Required Consents that are excluded at Closing pursuant to this Section 5.5, for a period of 180 days after Closing, Seller and Buyer shall use their respective commercially reasonable efforts to obtain all Consents listed on Schedule 7.4 (and any Consent that is not set forth on Schedule 7.4 but is discovered by either Party after the Execution Date and before the Closing Date); provided, however, that neither Party shall be required to expend any monies or undertake any obligations (other than requesting such Consents) in order to obtain any such Consent (other than any ordinary course transfer fees expressly set forth in the underlying instrument, which transfer fees are described on Schedule 5.5(b)(iii) (which shall be borne by Buyer)). Subject to the foregoing, Buyer agrees to cooperate in good faith with Seller to provide Seller with any information or documentation that may be reasonably requested in writing by Seller and/or the Third Party holder(s) of such Consents in order to facilitate the process of obtaining such Consents, if, and to the extent, such requested information or documentation is in Buyer’s or any of its Affiliates’ possession or control and is not subject to any confidentiality and/or non-disclosure restrictions prohibiting or restricting Buyer’s disclosure thereof.

(iv) Other than Post-Closing Consents, Required Consents, Medium Consents or the FCC Consents, if Seller fails to obtain a Consent, and as of such date, there is no pending or threatened dispute, disagreement or Proceeding with respect to any matter related to such Consent and such Consent has not been denied in writing, then the Conveyed Interest(s) (or portion(s) thereof) subject to such un-obtained Consent shall nevertheless be assigned by Seller to Buyer at Closing as part of the Conveyed Interests and Buyer shall have no claim against Seller and hereby releases and indemnifies the Seller Indemnified Parties from any Liability to the extent arising from the failure to obtain such Consent.

(c) With respect to any Post-Closing Consents or any post-Closing notice or other similar requirements applicable to the transfer of the Conveyed Interests in connection with the transactions contemplated hereby (“Buyer Consent/Notice Requirements”), (i) Buyer shall use commercially reasonable efforts to comply with such Buyer Consent/Notice Requirements, (ii) Buyer shall have no claim against, and hereby releases and indemnifies the Seller Indemnified Parties from any Liability to the extent relating to compliance with such Buyer Consent/Notice Requirements, (iii) Buyer assumes and shall be solely responsible from and after Closing for any Liabilities arising from the failure to comply with or to have obtained any such Buyer Consent/Notice Requirements and (iv) Seller shall cooperate in good faith with Buyer in connection with any such Buyer Consent/Notice Requirements.

(d) The provisions of this Section 5.5 shall apply mutatis mutandis to the applicable Affiliate of Seller (versus Seller) in the case of any of the Conveyed Interests are owned by such Affiliate of Seller; provided, however, that, notwithstanding the foregoing, Seller shall (i) cause such Affiliates to comply with and fulfill any and all such applicable obligations set forth in this Section 5.5 and (ii) remain liable and responsible for all purposes of this Agreement for any such Affiliate’s failure to comply with and fulfill any such obligations set forth in this Section 5.5.

ARTICLE VI

ENVIRONMENTAL MATTERS

6.1 Environmental Defects.

(a) Assertions of Environmental Defects. As a condition to Buyer asserting any claim with respect to any alleged Environmental Defect, Buyer must deliver claim notices to Seller meeting the requirements of this Section 6.1(a) (collectively the “Environmental Defect Notices” and individually an “Environmental Defect Notice”) not later than the Environmental Defect Claim Date setting forth any matters which, in Buyer’s reasonable opinion, constitute Environmental Defects and which Buyer intends to assert as Environmental Defects pursuant to this Section 6.1. Subject to, and without limitation of, clause (vi) of Schedule 13.1(b) and Seller’s representations and warranties set forth in Section 7.18 (and, in each case, Seller’s indemnity obligations related thereto), for all other purposes of this Agreement, Buyer shall be deemed to have waived, and Seller shall have no Liability for, (i) any Environmental Defect which Buyer fails to assert as an Environmental Defect by a timely and properly delivered Environmental Defect Notice received by Seller before the Environmental Defect Claim Date and (ii) any Environmental Condition that is not an Environmental Defect, with such liabilities becoming “Buyer’s Environmental Liabilities.” To be effective, each Environmental Defect Notice shall be in writing and shall include (A) a description of the matter constituting the alleged Environmental Defect (including the applicable Environmental Law violated or implicated thereby, if any) and the Conveyed Interest(s) affected by such alleged Environmental Defect (each, an “Environmental Defect Property”), (B) the Allocated Value of each Environmental Defect Property (or portions thereof) affected by such alleged Environmental Defect, as applicable (provided nothing herein shall prevent Buyer from asserting an Environmental Defect for a Conveyed Interest where the Allocated Value is zero), (C) supporting documents reasonably necessary for Seller to identify the existence of such alleged Environmental Defect (any and all of which supporting documents may be furnished via access to a web link or ftp site (in lieu of other means of delivery)), and (D) a calculation of the Remediation Amount (itemized in reasonable detail) that Buyer asserts is attributable to such alleged Environmental Defect with respect to each Environmental Defect Property. Notwithstanding anything to the contrary in this Agreement, the failure of an Environmental Defect Notice to include any of the information or documentation identified or described in Section 6.1(a)(A) through Section 6.1(a)(D) above shall not render such Environmental Defect Notice void or ineffective if such Environmental Defect Notice otherwise materially complies with the requirements set forth in this Section 6.1(a) and provides Seller with sufficient information to evaluate the alleged Environmental Defect. Buyer’s calculation of the Remediation Amount included in the Environmental Defect Notice must describe in reasonable detail the Remediation proposed for the alleged Environmental Defect that gives rise to the asserted Environmental Defect and identify all assumptions used by Buyer in calculating the Remediation Amount, including the standards that Buyer asserts must be met to comply with Environmental Laws.

(b) Seller’s Right to Cure. Seller shall have the right, but not the obligation, to cure any asserted Environmental Defect on or before the Closing Date (the “Environmental Defect Cure Deadline”). To give Seller an opportunity to commence reviewing and curing Environmental Defects, Buyer agrees to use reasonable efforts to give Seller written notice of all alleged Environmental Defects discovered by Buyer as soon as practical under the circumstance, which notice may be preliminary in nature and supplemented prior to the Environmental Defect Claim Date; provided that the failure to deliver such preliminary notice shall not affect Buyer’s right to submit an Environmental Defect Notice with respect to such Environmental Defects. An election by Seller to attempt to cure an Environmental Defect shall be without prejudice to its other rights under this Section 6.1 and shall not constitute an admission against interest or a waiver of Seller’s right to dispute the existence, nature or value of, or cost to Remediate, the alleged Environmental Defect. Seller shall be entitled to provide Buyer notice of Seller’s election to cure any Environmental Defect no later than 5 Business Days after the Environmental Defect Claim Date, and the failure to provide notice by such date shall be deemed an election not to cure (or to attempt to cure) by Seller.

29

(c) Remedies for Environmental Defects. Subject to Seller’s right to dispute the existence of an Environmental Defect in accordance with Section 6.1(f) and/or the Remediation Amount asserted with respect thereto, and subject to the limitations in Section 6.1(e) and the rights of the Parties pursuant to Section 14.1(f), in the event that Seller has not cured an Environmental Defect that has been timely and properly asserted by Buyer in accordance with Section 6.1(a) by the expiration of the Environmental Defect Cure Deadline and such Environmental Defect has not been waived by Buyer, Seller shall elect to:

(i) reduce the Purchase Price or Final Price, as applicable, by the applicable Remediation Amount; or

(ii) retain the entirety of the applicable Environmental Defect Property, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Environmental Defect Property, provided the remedy set forth in this Section 6.1(c)(ii) shall only be available, if the Remediation Amount applicable to such Environmental Defect equals or exceeds the greater of (A) seventy-five percent (75%) of the Allocated Value of the applicable Environmental Defect Property and (B) $750,000, and, in each case of an Environmental Defect Property that is not a Lease or Well, the applicable Environmental Defect Property would not be, as determined by Buyer in good faith, material with respect to the use, value or operation of the Conveyed Interests related to and including such Environmental Defect Property, taken as a whole, from and after the Closing; provided that Buyer shall have the right to elect the remedy set forth in this Section 6.1(c)(ii) if such remedy is available but is not elected by Seller. In connection with the remedy set forth in this Section 6.1(c)(ii), Seller acknowledges and agrees that (y) it shall retain all Liabilities and obligations of any kind related or applicable to any such Environmental Defect Property (including, for purposes of clarity, with respect to the Environmental Defect(s) applicable thereto) and (z) such Environmental Defect Property shall thereafter constitute an Excluded Asset and Other Matters for all purposes of this Agreement.

In the event that, as of the Closing Date, there are Environmental Defects with respect to which (A) Seller has not elected to Remediate pursuant to Section 6.1(b) or failed to Remediate all or part thereof prior to the Environmental Defect Cure Deadline and (B) Seller has not disputed the alleged Environmental Defect or the alleged Remediation Amount, the Purchase Price shall be reduced at Closing by the aggregate Remediation Amount of such Environmental Defects (or, the Allocated Value of the applicable Environmental Defect Property in the event Seller has retained such Environmental Defect Property pursuant to this Section 6.1(c)(ii)), subject to the limitations in Section 6.1(e). If Seller and Buyer are unable to agree on the existence or scope of any Environmental Defect or the Remediation Amount at the Closing, Buyer’s good faith determination with respect to such Environmental Defect or Remediation Amount shall be utilized for purposes of determining the Defect Escrow Amount at the Closing. If the Purchase Price is reduced for any Environmental Defect pursuant to this Section 6.1 or if the Purchase Price would have been reduced for any Environmental Defect but for the application of the Individual Environmental Threshold or the Environmental Defect Deductible, Buyer shall be deemed to have assumed responsibility for such Environmental Defect and for all Liabilities with respect thereto and Buyer’s obligations with respect to the foregoing shall be deemed to constitute Assumed Obligations. Subject to and without limitation of, clause (vi) of Schedule 13.1(b) and Seller’s representations and warranties set forth in Section 7.18 (and, in each case, Seller’s indemnity obligations related thereto) and Buyer’s rights to terminate this Agreement pursuant to Section 14.1(f), Buyer shall also be deemed to have assumed responsibility for any and all Environmental Conditions which do not constitute an Environmental Defect under this Agreement and for all Liabilities with respect thereto and Buyer’s obligations with respect to the foregoing shall be deemed to constitute Assumed Obligations.

30

(d) Exclusive Remedy. Subject to and without limitation of, clause (vi) of Schedule 13.1(b) and Seller’s representations and warranties set forth in Section 7.18 (and, in each case, Seller’s indemnity obligations related thereto) and Buyer’s rights to terminate this Agreement pursuant to Section 14.1(f) or under Article XIII solely with respect to clauses (vi) and (viii) of Schedule 13.1(b), to any Environmental Condition with respect to any Conveyed Interest or other environmental matter. With respect to all Non-Cost Bearing Interests, (i) there shall be deemed to be no Environmental Defect and (ii) Buyer shall not be entitled to assert Environmental Defects with respect to such interests.

(e) Environmental Threshold and Deductible. (i) Subject to the last sentence of this Section 6.1(e), in no event shall there be any adjustment to the Purchase Price or other remedies provided by Seller for any individual Environmental Defect for which the Remediation Amount (net to Seller’s interests) for an Environmental Defect Property does not exceed $[***] (the “Individual Environmental Threshold”); and (ii) in no event shall there be any adjustment to the Purchase Price or other remedies provided by Seller for any Environmental Defect for which the Remediation Amount for an Environmental Defect Property exceeds the Individual Environmental Threshold unless (A) the amount of the sum of the aggregate Remediation Amounts of all such Environmental Defect Properties where the Individual Environmental Threshold is exceeded (but excluding any Remediation Amounts attributable to any Environmental Defects to the extent cured by Seller prior to the Environmental Defect Cure Deadline and any Conveyed Interests subject to Environmental Defects that are retained by Seller, pursuant to Section 6.1(c)(ii)) exceeds (B) an amount equal to one percent (1%) of the unadjusted Purchase Price, or, in the event Seller does not acquire the Other Working Interest Owner Interests prior to the Closing Date in accordance with Section 9.14, the amount equal to [***]percent ([***]%) of the unadjusted Purchase Price less the Allocated Other Working Interest Owner Amount (the “Environmental Defect Deductible”), after which point Buyer shall be entitled to adjustments to the Purchase Price or other applicable remedies available hereunder, but only to the extent that the amount by which the sum of clause (A) above exceeds the Environmental Defect Deductible. If an individual Environmental Defect affects more than one Environmental Defect Property, the Remediation Amounts for each such Environmental Defect Property shall be aggregated for purposes of determining whether the Remediation Amounts of any such Environmental Defects in the aggregate exceed the Individual Environmental Threshold. For the avoidance of doubt, if an Environmental Defect is of a similar type or circumstance as another Environmental Defect (e.g., Environmental Defects related to separate air permits), such Environmental Defects shall not be aggregated for purposes of determining the Individual Environmental Threshold.

(f) Environmental Dispute Resolution. Seller and Buyer shall attempt to agree on (i) all Environmental Defects and Remediation Amounts prior to the Environmental Defect Cure Deadline and (ii) the adequacy of any cure by Seller of any asserted Environmental Defect prior to the Environmental Defect Cure Deadline (any disagreements between the Parties as to items (i) and/or (ii), collectively, the “Disputed Environmental Matters”). If Seller and Buyer are unable to agree by the Environmental Defect Cure Deadline, the Disputed Environmental Matters shall be exclusively and finally resolved by arbitration pursuant to this Section 6.1(f). There shall be a single arbitrator, who shall be an environmental attorney with at least 15 years’ experience pertaining to environmental matters involving oil and gas producing properties in the State of Texas, as selected by the mutual agreement of Buyer and Seller within 15 days after the Dispute Date (the “Environmental Arbitrator”). If the Parties do not mutually agree upon the Environmental Arbitrator in accordance with this Section 6.1(f), the Houston, Texas office of the AAA shall appoint such Environmental Arbitrator under such conditions as the AAA in its sole discretion deems necessary or advisable. The place of arbitration shall be Houston, Texas, and the arbitration shall be conducted in accordance with the AAA Rules, to the extent such rules do not conflict with the terms of this Section 6.1(f). Each of Buyer and Seller shall submit to the Environmental Arbitrator, with a simultaneous copy to the other Party, a single written statement of its position on the Disputed Environmental Matters in question, together with a copy of this Agreement and any supporting material that such Party desires to furnish, not later than the tenth Business Day after appointment of the Environmental Arbitrator. The

31

Environmental Arbitrator’s determination shall be made within 20 days after the end of such ten Business Day period after the submission of the Disputed Environmental Matters and shall be final and binding upon both Parties, without right of appeal and shall be enforceable against the Parties in a court of competent jurisdiction. Once appointed, the Environmental Arbitrator shall have no ex parte communication with either Party related to Disputed Environmental Matters. In making his determination, the Environmental Arbitrator shall make a determination of the Disputed Environmental Matters submitted based solely on the single written submission of Seller and Buyer (and without any additional or supplemental submittals by any Party, except to the extent the Environmental Arbitrator requests additional information from either Party), shall be bound by the rules set forth in this Section 6.1 and, subject to the foregoing, may consider such other legal and industry matters as in the opinion of the Environmental Arbitrator are necessary or helpful to make a proper determination. The Environmental Arbitrator, however, may not award Buyer a greater Remediation Amount than the Remediation Amount claimed by Buyer in its applicable Environmental Defect Notice. The Environmental Arbitrator shall act as an expert for the limited purpose of determining specific Disputed Environmental Matters submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter, except as otherwise provided in the following sentence. The costs of the Environmental Arbitrator (and the AAA, if applicable) and the reasonable legal costs and expenses incurred by the Parties in connection with the arbitration shall be borne pro rata between the Parties with each Party being responsible for such costs and expenses to the extent the Environmental Arbitrator has not selected such Party’s position on an aggregate dollar basis with respect to all amounts submitted for resolution by the Environmental Arbitrator. To the extent that the award of the Environmental Arbitrator with respect to any Remediation Amount is not taken into account as an adjustment to the Purchase Price in the Final Settlement Statement, then within ten days after the date the Environmental Arbitrator delivers written notice to Buyer and Seller of his award with respect to any Remediation Amount, and, subject to Section 6.1(e), the amount, if any, so awarded to a Party shall first, be satisfied out of the balance of the Defect Escrow Amount remaining after application of Section 3.6(b) and, then, if applicable, the owing Party shall pay to the owed Party any outstanding awarded amounts. Notwithstanding anything herein to the contrary, if there is any dispute as to an Environmental Defect that affects whether either Party may elect to exclude the Environmental Defect Property pursuant to Section 6.1(c)(ii) with respect to an Environmental Defect, then the applicable Environmental Defect Property shall be excluded from the Conveyed Interests assigned at Closing and the Allocated Value of such Environmental Defect Property shall be paid into the Escrow Account at Closing. If the Environmental Arbitrator determines that such Party does not have the right to elect to exclude the Environmental Defect Property pursuant to Section 6.1(c)(ii) with respect to an Environmental Defect, then within ten days after the date on which the Environmental Arbitrator delivers written notice to Buyer and Seller of such determination, (A) Seller shall assign to Buyer the retained Environmental Defect Property pursuant to an instrument in substantially the same form as the Assignment and (B) the Allocated Value less the determined Remediation Amount, if any, shall first, be paid to Seller out of the balance of the Defect Escrow Amount remaining after the application of Section 3.6(b) and, then, if applicable, by Buyer.

(g) Walk-Right Environmental Dispute Resolution. In the event a Party notifies the other Party of the intention to terminate this Agreement in accordance with Section 14.1(f), Seller or Buyer may, prior to giving effect to Section 14.1(f), as applicable, elect to submit all Disputed Environmental Matters to the Environmental Arbitrator in accordance with the procedures set forth in Section 6.1(f); provided, that notwithstanding anything to the contrary in Section 6.1(f), such proceeding shall be solely to determine whether the aggregate adjustments pursuant to Section 10.4 or Section 11.4, as applicable, in respect of any Disputed Environmental Matters would, when taken together with all other adjustments pursuant to Section 10.4 or Section 11.4, trigger the termination right under Section 14.1(f). For the avoidance of doubt, if Seller or Buyer elect to submit to the Environmental Arbitrator in accordance with this Section 6.1(g), no Party may terminate this Agreement pursuant to Section 14.1(f) until final resolution of such arbitration unless the termination right under Section 14.1(f) would otherwise apply solely by virtue of any undisputed Remediation Amounts, together the other aggregate adjustments pursuant to Section 10.4 or Section 11.4, as applicable.

32

6.2 NORM, Asbestos, Wastes and Other Substances. Buyer acknowledges that the Conveyed Interests have been used for exploration, development, and production of oil and gas and that there may be petroleum, produced water, wastes, or other substances or materials located in, on or under the Conveyed Interests or associated with the Conveyed Interests. Equipment and sites included in the Conveyed Interests may contain asbestos, NORM or other Hazardous Substances. NORM may affix or attach itself to the inside of wells, materials, and equipment as scale, or in other forms. The wells, materials, and equipment located on the Conveyed Interests or included in the Conveyed Interests may contain asbestos, NORM and other wastes or Hazardous Substances. NORM containing material and/or other wastes or Hazardous Substances may have come in contact with various environmental media, including water, soils or sediment. Special procedures may be required for the assessment, remediation, removal, transportation, or disposal of any affected environmental media, wastes, asbestos, NORM and other Hazardous Substances from the Conveyed Interests. Notwithstanding anything in this Agreement to the contrary, Buyer shall not be permitted to claim any Environmental Defect on the account of the presence of NORM or asbestos-containing materials that are non-friable, unless and only to the extent such presence of NORM or asbestos-containing materials that are non-friable constitutes an Environmental Condition resulting in a violation of Environmental Laws.

Notwithstanding anything to the contrary, (i) Seller shall in no event be required to create new records or financial statements relating to the Conveyed Interests or otherwise and (ii) the access to be provided to Buyer shall not interfere with Seller’s ability to prepare its own financial statements or its regular conduct of business. Seller and its Affiliates shall not be required to (A) deliver or cause the delivery of any legal opinions or make any representations in connection with such cooperation described herein, (B) take any action that Seller reasonably believes could result in a violation of applicable Law, Seller’s, or such Affiliate’s, organization documents, any contractual obligation or any confidentiality arrangement or the waiver of any legal or other applicable privilege, (C) agree to pay any fees, reimburse any expenses, incur any costs or Liabilities (unless Buyer has advanced the funds necessary to cover such expenses, costs or Liabilities) or give any indemnities; provided, however, nothing in this clause (C) shall be construed to limit Seller’s express obligations set forth in this Section 9.15 or (D) be a party to any agreement, certificate, instrument or other document with respect to the Buyer’s debt or equity financings.

(a) For purposes of Sections 4.1(c) and 9.3, and this Article XIII, the term “Indemnifying Party” when used in connection with particular Liabilities shall mean the Party or Parties having an obligation to indemnify another Party and/or other Person(s) with respect to such Liabilities pursuant to Sections 4.1(c) and 9.3, or this Article XIII, and the term “Indemnified Party” when used in connection with particular Liabilities shall mean the Party and/or other Person(s) having the right to be indemnified with respect to such Liabilities by the Indemnifying Party pursuant to Sections 4.1(c) and 9.3, or this Article XIII.

(b) To make a claim for indemnification under Sections 4.1(c), 5.5(b), 5.5(c), 9.3, 9.15, 13.2 or 13.3, an Indemnified Party shall promptly notify the Indemnifying Party in writing of its claim under this Section 13.7, including, the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a Third Party against the Indemnified Party (a “Third Party Claim”), the Indemnified Party shall provide its Claim Notice promptly after the Indemnified Party has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 13.7(b) shall not relieve the Indemnifying Party of its obligations under Sections 4.1(c), 5.5(b), 5.5(c), 9.3, 9.15, 13.2 or 13.3 (as applicable) except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise materially prejudices the Indemnifying Party’s ability to defend against the Third Party 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 Third Party Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim Notice to notify the Indemnified Party whether it admits or denies its obligation to defend and indemnify the Indemnified Party against such Third Party Claim at the sole cost and expense of the Indemnifying Party. The Indemnified Party is authorized, prior to and during such 30-day period, at the expense of the Indemnifying Party, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party.

(d) If the Indemnifying Party admits its obligation to defend and indemnify the Indemnified Party against a Third Party Claim, it shall have the right and obligation to diligently defend and indemnify, at its sole cost and expense, the Indemnified Party against such Third Party Claim. Subject to this Section 13.7(d), the Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified

61

Party agrees to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest. The Indemnified Party may participate in, but not control, at its own expense (except for and excluding any Third Party Claim which is finally determined to be covered under Seller’s indemnification obligations set forth in clause (xi) of Schedule 13.1(b)), any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 13.7(d). An Indemnifying Party shall not, without the written consent of the Indemnified Party, (i) settle any Third Party Claim or consent to the entry of any judgment with respect thereto which does not include an unconditional written release of the Indemnified Party from all Liability in respect of such Third Party Claim or (ii) settle any Third Party Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity).

(e) If the Indemnifying Party does not admit its obligation, or admits its obligation to defend and indemnify the Indemnified Party against a Third Party Claim but fails to diligently prosecute, indemnify against or settle such Third Party Claim, then the Indemnified Party shall have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying Party, with counsel of the Indemnified Party’s choosing, subject to the right of the Indemnifying Party to admit its liability and assume the defense of the Third Party Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet admitted its obligation to defend and indemnify the Indemnified Party against a Third Party Claim, the Indemnified Party shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for ten days following receipt of such notice to (i) admit in writing its obligation to indemnify the Indemnified Party from and against the liability and consent to such settlement, (ii) if liability is so admitted, reject, in its reasonable judgment, the proposed settlement, or (iii) deny liability. Any failure by the Indemnifying Party to respond to such notice shall be deemed to be an election under subsection (iii) above.

(f) In the case of a claim for indemnification not based upon a Third Party Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim Notice to (i) cure the Liabilities complained of, (ii) admit its liability for such Liability or (iii) dispute the claim for such Liabilities. If the Indemnifying Party does not notify the Indemnified Party within such 30-day period that it has cured the Liabilities or that it disputes the claim for such Liabilities, the Indemnifying Party shall be deemed to dispute the claim for such Liabilities.

(g) Notwithstanding anything to the contrary in this Agreement, except as provided in clause (iv) of Schedule 13.1(b), the Parties acknowledge and agree that an Indemnified Party shall have the right (in its discretion) to assert, without duplication of recovery with respect to the same claim, a claim under applicable clause of Section 13.2 or Section 13.3, as applicable, even if such claim could be brought under, or is foreclosed from being brought under, any other clause of Section 13.2 or Section 13.3, as applicable, for any reason.

63

(d) by Buyer, at Buyer’s option, if (i) any of the conditions set forth in Article X (other than Section 10.4 and Section 10.6) have not been satisfied (or waived in writing by Buyer) as of the Scheduled Closing Date (or the CFIUS Closing Date, if applicable), and, following written notice thereof from Buyer to Seller specifying the reason such condition is unsatisfied (including any breach by Seller of this Agreement), such condition remains unsatisfied for a period of ten Business Days after Seller’s receipt of written notice thereof from Buyer and (ii) as of the Scheduled Closing Date (or the CFIUS Closing Date, if applicable), Buyer is ready, willing and able (subject to obtaining or satisfying the Regulatory Approvals) to perform all of its agreements contained herein which are to be performed or observed by Buyer at or in connection with the Closing;

provided, however, that neither Party shall be entitled to terminate this Agreement pursuant to Sections 14.1(b) through 14.1(e) above if such Party or its Affiliates are, at such time, in material breach of this Agreement.

14.2 Effect of Termination.

(a) If this Agreement, including the obligation to close the transactions contemplated hereby, is terminated pursuant to any provision of Section 14.1 hereof, then, except for the provisions of Article I, Sections 4.1(c) through 4.1(e), 4.2, 4.3, 9.6(a), 9.15, 13.9, this Section 14.2, Section 14.3, Article XV (other than Sections 15.2(a) through (g), 15.7, 15.8, 15.16, and 15.18) and such of the defined terms in Appendix I to give context to the surviving provisions, this Agreement shall forthwith become void and the Parties shall have no Liability or obligation hereunder.

(b) If Seller has the right to terminate this Agreement pursuant to Section 14.1(c) because a condition set forth in Sections 11.1, 11.2, or 11.5 has not been satisfied, (A) all of the conditions in Article X (excluding (i) conditions that, by their terms, cannot be satisfied until the Closing and (ii) the condition set forth in Section 10.6) have been satisfied (or waived in writing by Buyer) (unless the failure to satisfy such condition arises from the action or inaction by Buyer or any Buyer Indemnified Party) and (B) Seller is ready, willing and able (subject to obtaining or satisfying the Regulatory Approvals) to perform its obligations under Section 12.3, then, in such event, Seller shall have the right to, at its option, as Seller’s sole and exclusive remedy, terminate this Agreement pursuant to Section 14.1(c) and Buyer shall be obligated to jointly with Seller instruct the Escrow Agent to disburse the Deposit to Seller as liquidated damages and not as a penalty for such termination, free and clear of any claims thereon by Buyer or any of its Affiliates, and thereafter, all other rights, remedies and obligations of any Party arising under this Agreement (except for the provisions that survive pursuant to Section 14.2(a), which shall remain in full force and effect) are hereby expressly waived by the Parties. THE PARTIES ACKNOWLEDGE AND AGREE THAT (x) SELLER’S ACTUAL DAMAGES RESULTING FROM A TERMINATION UNDER SECTION 14.1(c) MAY BE DIFFICULT, IF NOT IMPOSSIBLE TO CALCULATE, (y) THE DEPOSIT IS A FAIR AND REASONABLE ESTIMATE OF SELLER’S LIQUIDATED DAMAGES IN LIGHT OF THE UNCERTAINTIES IN CALCULATING THE ACTUAL DAMAGES THAT WOULD BE SUFFERED BY SELLER UNDER THE CIRCUMSTANCES SET FORTH IN THIS SECTION 14.2(b) AND (z) SUCH LIQUIDATED DAMAGES ARE NOT A PENALTY.

64

(c) If Buyer has the right to terminate this Agreement pursuant to Section 14.1(d) because a condition set forth in Sections 10.1, 10.2 or 10.5 has not been satisfied, (A) all of the conditions in Article XI (excluding (i) conditions that, by their terms, cannot be satisfied until the Closing and (ii) the condition set forth in Section 11.6) have been satisfied (or waived in writing by Seller) (unless the failure to satisfy such condition arises from the action or inaction by Seller or any Seller Indemnified Party) and (B) Buyer is ready, willing and able (subject to obtaining or satisfying the Regulatory Approvals) to perform its obligations under Section 12.3, then, in such event, Buyer shall have the right, at its option, to (i) in lieu of terminating this Agreement, to obtain all remedies available at law or in equity, including specific performance by Seller or (ii) terminate this Agreement by written notice to Seller and Seller shall be obligated to jointly with Buyer instruct the Escrow Agent to disburse the Deposit to Buyer, free and clear of any claims thereon by, through or under Seller or any of its Affiliates, and thereafter, all other rights, remedies and obligations of any Party arising under this Agreement (except for the provisions that survive pursuant to Section 14.2(a), which shall remain in full force and effect) are hereby expressly waived by the Parties. Seller hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to specifically enforce the terms and provisions of this Agreement pursuant to this Section 14.2(c). Buyer shall not be required to provide any bond or other security in connection with seeking an injunction or injunctions to enforce specifically the terms and provisions of this Agreement pursuant to this Section 14.2(c).

(d) Without limitation of any of Buyer’s rights or remedies under Section 14.2(c) above, in the event that (i) this Agreement is terminated under Section 14.1 and (ii) Seller is not entitled to receive the (y) Deposit under Section 14.2(b) or (z) CFIUS Termination Fee under Section 14.2(e), then Seller and Buyer shall, within two (2) Business Days of the date of such termination, jointly instruct the Escrow Agent to disburse to Buyer the Deposit, free and clear of any claims thereon by, through or under Seller or any of its Affiliates. For the avoidance of doubt, if the Agreement is terminated by either Party (A) pursuant to Section 14.1(f) or (B) any other provision set forth in Section 14.1 and at the time of such termination the conditions set forth in Section 10.4 or Section 11.4 are not satisfied, then, notwithstanding the foregoing, Seller and Buyer shall, within two (2) Business Days of the date of such termination, jointly instruct the Escrow Agent to disburse to Buyer the Deposit, free and clear of any claims thereto by, through or under Seller or any of its Affiliates.

(e) If (i) Seller or Buyer terminates this Agreement pursuant to Section 14.1(e) or (ii) Seller or Buyer terminate this Agreement pursuant to Section 14.1(b) and Section 10.6 (as it relates to CFIUS) and Section 11.6 (as it relates to CFIUS) have not been satisfied, then Seller and Buyer shall, within two (2) Business Days of the date of such termination, jointly instruct the Escrow Agent to disburse to Seller the Deposit as the CFIUS Termination Fee as Seller’s sole and exclusive remedy for such termination as liquidated damages and not as a penalty, free and clear of any claims thereon by, through or under Buyer or any of its Affiliates. THE PARTIES ACKNOWLEDGE AND AGREE THAT (x) SELLER’S ACTUAL DAMAGES RESULTING FROM A TERMINATION DESCRIBED IN THE FIRST SENTENCE OF THIS SECTION 14.2(E), MAY BE DIFFICULT, IF NOT IMPOSSIBLE TO CALCULATE, (y) THE CFIUS TERMINATION FEE IS A FAIR AND REASONABLE ESTIMATE OF SELLER’S LIQUIDATED DAMAGES IN LIGHT OF THE UNCERTAINTIES IN CALCULATING THE ACTUAL DAMAGES THAT WOULD BE SUFFERED BY SELLER UNDER THE CIRCUMSTANCES SET FORTH IN THIS SECTION 14.2(E) AND (z) SUCH LIQUIDATED DAMAGES ARE NOT A PENALTY.

14.3 Return of Documentation and Confidentiality. Upon termination of this Agreement, Buyer shall destroy or return to Seller all title, engineering, geological and geophysical data, environmental assessments and/or reports, maps and other information furnished by or on behalf of Seller to Buyer or prepared by or on behalf of Buyer in connection with its due diligence investigation of the Conveyed Interests, in each case, in accordance with the Confidentiality Agreement and, if Buyer elects to destroy any such information, an officer of Buyer shall certify the destruction of such information to Seller in writing.

ARTICLE XV

MISCELLANEOUS

15.1 Appendices, Exhibits and Schedules. All of the Appendices, Exhibits and Schedules referred to in this Agreement are hereby incorporated into this Agreement by reference and constitute a part of this Agreement. Each Party to this Agreement and its counsel have received a complete set of Appendices, Exhibits and Schedules prior to and as of the execution of this Agreement.

15.2 Expenses and Taxes. Except as otherwise specifically provided in this Agreement, all fees, costs and expenses incurred by the Parties in negotiating this Agreement or in consummating the transactions contemplated by this Agreement shall be paid by the Party incurring the same, including legal and accounting fees, costs and expenses.

(a) Seller shall be allocated and bear all Asset Taxes attributable to any Tax period (or portion of any Straddle Period) ending prior to the Effective Time, and Buyer shall be allocated and bear all Asset Taxes attributable to any Tax period (or portion of any Straddle Period) that begins at or after the Effective Time.

(b) For purposes of determining the allocations in Section 15.2(b), (i) Asset Taxes that are attributable to the severance or production of Hydrocarbons (other than such Asset Taxes described in clause (iii), below) shall be allocated to the period in which the severance or production giving rise to such Asset Taxes occurred, (ii) Asset Taxes that are based upon or related to sales or receipts or imposed on a transactional basis (other than such Asset Taxes described in clause (i) or (iii)), shall be allocated to the period in which the transaction giving rise to such Asset Taxes occurred, and (iii) Asset Taxes that are ad valorem, property or other Asset Taxes imposed on a periodic basis pertaining to a Straddle Period shall be allocated between the portion of such Straddle Period ending immediately prior to the Effective Time and the portion of such Straddle Period beginning at the Effective Time by prorating each such Asset Tax based on the number of days in the applicable Straddle Period that occur before the date on which the Effective Time occurs, on the one hand, and the number of days in such Straddle Period that occur on or after the date on which the Effective Time occurs, on the other hand. For purposes of clause (iii) of the preceding sentence, the period for such Asset Taxes shall begin on the date on which ownership of the applicable Conveyed Interests gives rise to Liability for the particular Asset Tax and shall end on the day before the next such date.

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

(d) Subject to the Transition Services Agreement:

(i) Subject to Section 15.2(d)(ii), after the Closing Date, Buyer shall (x) be responsible for paying any Asset Taxes relating to any Tax period that ends before or includes the Closing Date that become due and payable after the Closing Date and shall file with the appropriate Taxing Authority any and all Tax Returns required to be filed after the Closing Date with respect to such Asset Taxes, (y) submit each such Tax Return to Seller for its review and comment reasonably in advance of the due date therefor, and (z) timely file any such Tax Return, incorporating any reasonable comments received from Seller prior to the due date therefor.

66

(ii) Notwithstanding Section 15.2(d)(i), and to the extent permissible under applicable Law, with respect to any Conveyed Interests of which Seller is the operator, Seller shall be responsible for the payment to the applicable Taxing Authority of any severance Asset Taxes through the production month in which the Closing occurs, and the preparation and timely filing of any Tax Return relating to such Asset Taxes, and the payment to the applicable Taxing Authority of any sales or use Asset Taxes attributable to any Tax period (or portion thereof) ending on or prior to the Closing Date, and the preparation and timely filing of any Tax Return relating to such Asset Taxes. Seller shall prepare (or cause to be prepared) in accordance with past practices (unless otherwise required by applicable Law) and file (or cause to be filed) the U.S. federal income Tax Return (and related Schedules K-1) of the Tarrant Salt Walter Disposal Joint Venture for the 2019 Tax period, and to the extent Seller or any of its Affiliates is appointed as the “partnership representative” (as defined in Section 6223 of the Code and the applicable Treasury Regulations) on such Tax Return, such Seller or Affiliate, as applicable, shall use commercially reasonable efforts to make a “push-out” election under Section 6226 of the Code with respect to any imputed underpayment that is asserted with respect to such Tax Return. Buyer shall prepare (or cause to be prepared) in accordance with past practices (unless otherwise required by applicable Law) and file (or cause to be filed) the U.S. federal income Tax Return (and related Schedules K-1) for the 2020 Tax period, allocating all items of income, gain, loss, deduction and credit allocable to the Water Disposal JV Interest between Seller and Buyer based on the “interim closing method” under Section 706 of the Code and the Treasury Regulations thereunder, and Buyer shall submit such Tax Return to Seller for its review and comment reasonably in advance of the due date therefor and timely file any such Tax Return incorporating any reasonable comments received from Seller prior to the due date therefor.

The Parties agree that (x) this Section 15.2(d) is intended to solely address the timing and manner in which certain Tax Returns relating to Asset Taxes are filed and the Asset Taxes shown thereon are paid to the applicable Taxing Authority, and (y) nothing in this Section 15.2(d) shall be interpreted as altering the manner in which Asset Taxes are allocated to and economically borne by the Parties or a Party’s right to indemnification pursuant to Article XIII (except for any penalties, interest or additions to Tax imposed as a result of any breach by a Party of its obligations under this Section 15.2(d), which shall be borne by such Party).

(e) All required documentary, filing and recording fees and expenses in connection with the filing and recording of the assignments, conveyances or other instruments required to convey title to the Conveyed Interests to Buyer shall be borne by Buyer. Any and all sales, use, transfer, stamp, documentary, registration or similar Taxes incurred or imposed with respect to the transactions described in this Agreement (collectively, “Transfer Taxes”) shall be borne by Buyer; provided that Seller shall pay or cause to be paid to the applicable Governmental Authorities any Transfer Taxes that it is required by Law to collect and remit; provided, however, that Seller shall not collect sales Tax with respect to the transfer of Hydrocarbons in storage pursuant to this Agreement to the extent that Buyer has provided to Seller at or prior to Closing a valid resale certificate establishing such transfer as an exempt sale for resale under applicable Law. Buyer shall indemnify and hold Seller harmless from and against such Transfer Taxes within 30 days of Seller’s written demand therefor. If Seller (not Buyer) is required by applicable Law to appeal or protest the assessment of Transfer Taxes, the appeal or protest of such proposed assessment shall be treated as an item for which Seller is entitled to indemnification and if Buyer provides a written request and instructs Seller to do so, Seller shall prosecute the protest or appeal; in such event Buyer shall pay all out-of-pocket expenses of Seller (including attorneys’ fees) incurred by Seller in connection with such appeal or protest. Seller and Buyer shall reasonably cooperate in good faith to minimize, to the extent permissible under applicable Law, the amount of any such Transfer Taxes.

67

(f) The Parties shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns and any audit, litigation, or other proceeding with respect to Taxes relating to the Conveyed Interests. Such cooperation shall include (i) the retention and (upon another Party’s request) the provision of records and information that are relevant to any such Tax Return or audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided under this Agreement, (ii) in connection with the provision of the Preliminary Settlement Statement and Final Settlement Statement, providing to Buyer supporting tax information used in the determination of the Preliminary Settlement Statement and Final Settlement Statement, including ad valorem and property tax information for the 2019 taxable period and the 2020 taxable period (to the extent such information is in Seller’s possession at such time and not otherwise in Buyer’s possession) identifying the type of property, relevant account numbers, tax collector and appraiser, status of the assessed property, percentage of ownership, taxable values, and the applicable gross tax liability, and (iii) with respect to the 2020 taxable period, prior to the Closing, authorizing Buyer and any of its applicable designees to engage with the applicable Taxing Authority in connection with determination of the values used in the assessment of ad valorem taxes of the Conveyed Interests and providing to Buyer any information reasonably requested by Buyer that is in Seller’s possession and relevant to making any such determination. The Parties agree to retain all books and records with respect to Tax matters pertinent to the Conveyed Interests relating to any Tax period beginning before the Closing Date until the later of (1) seven years or (2) the expiration of the statute of limitations of the respective Tax periods and to abide by all record retention agreements entered into with any Governmental Authority.

(g) Seller shall reasonably cooperate with Buyer to cause the Tarrant Salt Water Disposal Joint Venture and any tax partnership identified on Schedule 7.12 to make a valid election under Section 754 of the Code (and any comparable elections for any applicable state income tax purposes) for the taxable year during which the Closing occurs.

15.3 Assignment. Subject to the provisions of Section 15.18, this Agreement may not be assigned by either Party without the prior written consent of the other Party and any such assignment without such consent shall be void ab initio. Notwithstanding the foregoing, Buyer shall have the right to designate an Affiliate of Buyer as an assignee for all or part of the Conveyed Interests to be conveyed by Seller at Closing. No assignment of any rights hereunder by a Party shall relieve such Party of any obligations and responsibilities hereunder. Any assignment or other transfer by Buyer or its successors and assigns of any of the Conveyed Interests shall not relieve Buyer or its successors or assigns of any of their obligations (including indemnity obligations) hereunder, as to the Conveyed Interests so assigned or transferred.

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

15.5 Publicity. Seller and Buyer shall promptly consult with each other with regard to all press releases or other public or private announcements issued or made at or prior to Closing concerning this Agreement or the transactions contemplated in this Agreement, and, except as may be required by applicable Laws or the applicable rules and regulations of any Governmental Authority or stock exchange or as described in the remaining provisions of this Section 15.5, neither Buyer nor Seller shall issue any such press release or other public or private announcement without the prior written consent of the other Party (which shall not be unreasonably withheld or delayed). Subject to, and without limitation of, Section 15.22, the

68

Parties and their Affiliates shall be obligated to hold all specific terms and provisions of this Agreement strictly confidential until the expiration of two years after the Closing under this Agreement; provided, however, that the foregoing shall not (a) restrict disclosures by Buyer or Seller that are required by applicable securities or other Laws or regulations or the applicable rules of any stock exchange having jurisdiction over the disclosing Party or its Affiliates; provided that such disclosures shall be made only to the extent required thereunder, (b) prevent Buyer or Seller from recording the Assignment, the SWGP Assignment, the DEC Assignment, the DGS Assignment, the DGS Surface Deed, any Deed and any federal or state assignments delivered at Closing or from complying with any disclosure requirements of Governmental Authorities that are applicable to the transfer of the Conveyed Interests from Seller to Buyer, (c) prevent Buyer or Seller from making any disclosure of information relating to this Agreement if made in a manner, under conditions and to Persons that would be permitted under the Confidentiality Agreement so long as such Person continues to hold such information confidential on the same terms as set forth in this Section 15.5, and (d) prevent Seller from making disclosures in connection with complying with Preferential Purchase Rights and other transfer restrictions applicable to the transactions contemplated hereby.

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