(viii) if applicable and to the extent not paid to Buyer, the amounts set forth in Section(i)(ii) of Schedule 9.23;

(c) For purposes of determining the amount of the adjustments to the Purchase Price provided for in this Section 2.3, the principles set forth in this Section 2.3(c) shall apply except as expressly provided otherwise in this Agreement. Subject to the preceding sentence and except for amounts for which the Purchase Price is adjusted hereunder: (i) Seller shall remain entitled to all of the rights of ownership (including the right to all production, proceeds of production and other proceeds, if any) and shall remain responsible for all Operating Expenses, in each case attributable to the Assets for the period of time prior to the Effective Time and all Excluded Assets, and (ii) subject to the occurrence of the Closing, each applicable Company shall be entitled to all of the rights of ownership (including the right to all production, proceeds of production and other proceeds) attributable to the Assets for the period of time from and after the Effective Time, and shall be responsible for all Operating Expenses attributable to the Assets for the period of time from and after the Effective Time. Such amounts that are received, paid or properly accrued prior to Closing shall be accounted for in the Preliminary Settlement Statement or Final Settlement Statement as applicable. From and after the date of the Final Settlement

4

Statement, (1) Buyer shall cause the applicable Company to fully disclose, account for and remit to Seller any revenues to which Seller is entitled pursuant to this Section 2.3(c) on or before the tenth day after each Company’s or its Affiliates’ receipt of same and (2) Seller shall fully disclose, account for and remit to the applicable Company any revenues to which such Company is entitled pursuant to this Section 2.3(c) on or before the tenth day after Seller’s or its Affiliates’ receipt of same. For the avoidance of doubt, the date an item or work is ordered is not the date of a transaction for settlement purposes in the Preliminary Settlement Statement or Final Settlement Statement, as applicable, but rather the date on which the item ordered is delivered to the job site, or the date on which the work ordered is performed, is the relevant date (i.e., on an accrual basis). “Earned” and “incurred”, as used in this Agreement, shall be interpreted in accordance with GAAP and COPAS standards, subject to the other provisions of this Section 2.3. For purposes of allocating production (and accounts receivable with respect thereto), under this Section 2.3, (a) liquid Hydrocarbons shall be deemed to be “from or attributable to” the Wells when they pass through the pipeline connecting into the storage facilities into which they are transported from the lands covered by the applicable Well, or if there are no storage facilities, when they pass through the LACT meter or similar meter at the entry point into the pipelines through which they are transported from such lands and (b) gaseous Hydrocarbons shall be deemed to be “from or attributable to” the Wells when they pass through the delivery point sales meters or similar meters at the entry point into the pipelines through which they are transported from such lands. The Parties shall utilize reasonable interpolative procedures to arrive at an allocation of production when exact meter readings (including gas production meters or sales meters) or gauging and strapping data is not available.

2.4 Preliminary Settlement Statement. No later than the twelfth (12^th) Business Day prior to the Closing Date, Seller shall prepare and submit to Buyer for review a draft settlement statement (the “Preliminary Settlement Statement”) that shall set forth an estimate of the Adjusted Purchase Price, reflecting Seller’s good faith estimate of each proposed adjustment to be made in accordance with Section 2.3 as of the date of preparation of such Preliminary Settlement Statement, together with the designation of Seller’s accounts for the wire transfers of funds as set forth in Section 11.3(a). Seller shall supply to Buyer reasonable documentation in the possession of Seller or any of its Affiliates to support the items for which adjustments are proposed or made in the Preliminary Settlement Statement delivered by Seller, and a brief explanation of any such adjustments and the reasons therefor. On or before the fifth (5^th) Business Day after Buyer’s receipt of the Preliminary Settlement Statement, Buyer shall deliver to Seller a written report containing all changes that Buyer proposes to be made to the Preliminary Settlement Statement, if any, together with an explanation of such changes. The Preliminary Settlement Statement, as agreed upon by the Parties, shall be used to calculate the Adjusted Purchase Price; provided that if the Parties do not agree on any of the adjustments set forth in the Preliminary Settlement Statement prior to the Closing, all unagreed upon adjustments (if any) set forth in the Preliminary Settlement Statement as presented by Seller in good faith shall be used to calculate the Adjusted Purchase Price; provided further that, if Buyer disagrees with Seller’s estimate of any adjustments set forth in Section 2.3(b)(iii) or Section 2.3(b)(iv), then Buyer’s good faith estimate of such adjustments shall be used in calculating the Adjusted Purchase Price as of the Closing Date for the purpose of determining the Adjusted Purchase Price.

5

2.5 Final Settlement Statement. On or before the date that is six months following the Closing Date, Seller shall submit to Buyer a final settlement statement (the “Final Settlement Statement”), based on actual adjustments to the Purchase Price and that takes into account all final adjustments made to the Purchase Price in accordance with Section 2.3 and shows the resulting final Adjusted Purchase Price. Seller shall supply to Buyer reasonable documentation in the possession of Seller or any of its Affiliates to support the items for which adjustments are proposed or made in the Final Settlement Statement delivered by Seller, and a brief explanation of any such adjustments and the reasons therefor. The Final Settlement Statement shall set forth the actual proration of the amounts required by this Agreement. On or before the 30^th Business Day after its receipt of the Final Settlement Statement, Buyer shall deliver to Seller a written report containing any proposed changes to the Final Settlement Statement and an explanation of any such changes and the reasons therefor (the “Dispute Notice”). Any changes not included in the Dispute Notice shall be deemed waived, and Seller’s determinations with respect to all such adjustments in the Final Settlement Statement that are not addressed in the Dispute Notice shall, without limiting Section 4.2(d), be final and binding on the Parties. If Buyer fails to timely 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 shall be deemed to be agreed upon by the Parties and shall, without limiting Section 4.2(d), be final and binding on the Parties. If the final Adjusted Purchase Price set forth in the Final Settlement Statement is agreed upon in writing by Seller and Buyer, the Final Settlement Statement and the final Adjusted Purchase Price as so agreed shall, without limiting Section 4.2(d), be final and binding on the Parties. If after a timely Dispute Notice the Parties do not agree in writing to any element of the Final Settlement Statement, the provisions of Section 2.6 shall apply. Once the final Adjusted Purchase Price has been agreed (or deemed agreed) upon by the Parties pursuant to this Section 2.5 or determined by the Accounting Referee pursuant to Section 2.6, as applicable, then, if the final Adjusted Purchase Price is (a) more than the Adjusted Purchase Price, Buyer shall pay to a bank account in the United States designated by Seller by notice to Buyer the amount of such difference or (b) less than the Adjusted Purchase Price, Seller shall pay to a bank account in the United States designated by Buyer by notice to Seller the amount of such difference, in each case, by wire transfer in immediately available funds no later than the fifth Business Day (or if later, the third Business Day after the Party to receive funds notifies the Party to pay funds of the account) after the date such final Adjusted Purchase Price is agreed, or deemed agreed, pursuant to this Section 2.5 or determined pursuant to Section 2.6, as applicable. Notwithstanding the foregoing or anything to the contrary in this Agreement, nothing in this Section 2.5 shall limit Buyer’s rights to exercise the dispute rights and audit rights in Section 3(b) and Section 3(c) of the Transition Services Agreement.

2.6 Disputes. If at any time after the 30th day following Seller’s receipt of the Dispute Notice Seller and Buyer have not resolved in writing all of the matters addressed in the Dispute Notice, Buyer or Seller, by notice to the other, may refer any remaining unagreed matters to an Accounting Referee. Each of Buyer and Seller shall, on or before the fifth Business Day after the Accounting Referee has agreed to serve as such or has been appointed by the Parties or the AAA, as applicable based on the definition of that term, summarize its position with regard to the disputed adjustments in a written document of 20 pages or less (not including any supporting documentation) and submit such summaries to the Accounting Referee, together with the Dispute Notice, the Final Settlement Statement and any other documentation such Party may desire to submit. Seller shall also furnish the Accounting Referee with a copy of this Agreement. The Parties shall instruct the Accounting Referee that, on or before the 15th Business Day after receiving the Parties’ respective submissions, the Accounting Referee shall render a decision

6

choosing either Seller’s position or Buyer’s position with respect to each disputed adjustment addressed in any Dispute Notice, whichever is accurate (or closer to the accurate amount) based on the terms of the Agreement and the materials described above. The Accounting Referee shall calculate only the disputed adjustments addressed in the Dispute Notice that have not otherwise been resolved and agreed upon in writing by Seller and Buyer after delivery of the Dispute Notice. Each choice between Seller’s position and Buyer’s position with respect to any disputed adjustment that is rendered by the Accounting Referee in accordance with this Section 2.6 shall, without limiting Section 4.2(d), be final and binding on Seller and Buyer and shall be enforceable against each of the Parties in any court of competent jurisdiction. The costs of such Accounting Referee shall be borne one half by Buyer and one half by Seller. The final Adjusted Purchase Price set forth in the Final Settlement Statement incorporating the adjustment amounts determined by the Accounting Referee in accordance with this Section 2.6, in addition to the adjustment amounts agreed to in writing by the Parties, shall, without limiting Section 4.2(d), be final and binding on the Parties. The Accounting Referee shall be authorized to resolve only the specific disputed aspects of the Final Settlement Statement submitted by the Parties as provided above and may not award damages, interest or penalties to any Party with respect to any matter. Notwithstanding the foregoing or anything to the contrary in this Agreement, nothing in this Section 2.6 shall limit Buyer’s rights to exercise the dispute rights and audit rights in Section 3(b) and Section 3(c) of the Transition Services Agreement.

2.7 Allocated Values. Seller and Buyer agree to allocate the Adjusted Purchase Price in accordance with the allocation schedule attached as Schedule 2.7 (the “Allocated Values”).

2.8 Purchase Price Allocation. The Adjusted Purchase Price and any other items properly treated as consideration for U.S. federal income tax purposes shall be allocated among the assets of the Companies in accordance with Section 1060 of the Code and the Treasury Regulations promulgated thereunder (and any similar provision of state, local or foreign law, as appropriate) (the “Allocation”). To the extent allowed under applicable federal income tax Law, the Allocation shall be prepared in a manner consistent with the Allocated Values set forth on Schedule 2.7. On or before the 90th day after the Closing Date, Buyer shall deliver to Seller the Allocation for Seller’s approval, which approval shall not be unreasonably withheld. Seller and Buyer shall work in good faith to resolve any disputes relating to the Allocation as promptly as practicable. At any time after the tenth day following Buyer’s delivery of the Allocation to Seller, if Seller and Buyer have not resolved any such dispute, such dispute shall be resolved promptly in accordance with the procedures set forth in Section 2.6. If the Purchase Price is adjusted pursuant to this Agreement, the Allocation shall be adjusted as mutually agreed by Buyer and Seller. Buyer and Seller shall file all Tax Returns (including Internal Revenue Service Form 8594) in a manner consistent with the Allocation. Neither Buyer nor Seller shall take any Tax position inconsistent with such Allocation, as adjusted, unless otherwise required by applicable Law; provided, however, that nothing contained herein shall prevent Buyer or Seller from settling any proposed deficiency or adjustment by any Governmental Authority based upon or arising out of the Allocation, and neither Buyer nor Seller shall be required to litigate before any court any proposed deficiency or adjustment by any Governmental Authority challenging such Allocation.

7

2.9 Deferred Payment Obligation. Within ten (10) days after termination of the Transition Services Agreement, Seller shall submit to Buyer an invoice for an amount equal to (a) the Deferred Payment Amount, minus (b) the actual aggregate amount of any sales proceeds from the Oil and Gas Properties attributable to the period after the Effective Time that are withheld by Seller pursuant to the terms of the Transition Services Agreement, minus (c) any portions of the Deferred Payment Amount that Buyer has previously paid to Seller (the resulting amount, the “Net Deferred Payment Amount”). Within fifteen days after Buyer’s receipt from Seller of such invoice, Buyer shall pay to Seller by wire transfer of immediately available funds to the account of Seller set forth in the Preliminary Settlement Statement the Net Deferred Payment Amount. Notwithstanding anything to the contrary in this Agreement, nothing shall limit Buyer’s dispute rights and audit rights set forth in Section 3(b) and Section 3(c) of the Transition Services Agreement with respect to the determination of the amounts set forth in clause (b) of the definition of Net Deferred Payment Amount. For clarity, Buyer shall have the right at any time after the Closing (and prior to the due date of the Net Deferred Payment Amount) to pay to Seller by wire transfer of immediately available funds to the account of Seller set forth in the Preliminary Settlement Statement all or any portion of the Deferred Payment Amount that then-remains outstanding.

ARTICLE 3

LOSS AND CASUALTY / INSPECTION OF ASSETS

3.1 Casualty Loss.

(a) Notwithstanding anything herein to the contrary, from and after the Effective Time, if Closing occurs, Buyer shall assume all risk of loss with respect to production of Hydrocarbons through normal depletion (including watering out of any Well, collapsed casing or sand infiltration of any Well) and the depreciation of Personal Property due to ordinary wear and tear, in each case, with respect to the Assets.

(b) If, after the Execution Date but prior to the Closing, any portion of the Assets suffers a Casualty Loss, then Buyer and Seller shall, subject to the satisfaction (or waiver) of the conditions to Closing set forth in Article 10, nevertheless be required to Close, and in the case of any individual Casualty Loss in excess of $1,000,000 in Casualty Loss Amount, Seller shall elect by notice to Buyer prior to Closing either (i) to cause, at Seller’s sole cost and expense, the Asset affected by such Casualty Loss to be repaired or restored to a quality and condition comparable to that existing with respect to the Asset as before such Casualty Loss as promptly as reasonably practicable (which work may extend after the Closing Date, but no longer than the Title Cure Period, so long as at the Closing Seller and the applicable Companies enter into an access and indemnity agreement in form and substance reasonably acceptable to the Parties and on substantially the same terms set forth with respect to Buyer’s pre-Closing access rights in Sections 3.3(c), (e) and (f) below with respect to Seller’s access to the Assets) or (ii) to reduce the unadjusted Purchase Price at Closing by the Casualty Loss Amount attributable to such Casualty Loss (and in the event Seller has made the election under the foregoing clause (i) but not completed such repair or restoration as of the Title Cure Period, then this clause (ii) shall apply to the extent and only to the extent of any unrepaired or unrestored damage); provided, however, that in no event shall Buyer be entitled to any remedy with respect to any Casualty Loss when the Casualty Loss Amount does not equal or exceed $1,000,000. With respect to any such Casualty Loss for which the Purchase Price is reduced pursuant to this Section 3.1(b) or which Seller has repaired or restored as provided in this Section 3.1(b), Seller shall be entitled to receive and retain as an Excluded Asset all of its and the Companies’ rights to insurance and other Claims with respect to such Casualty Loss, except to the extent the Parties otherwise agree in writing.

8

3.2 Insurance Matters. Buyer understands and agrees that, from and after the Closing, (a) no insurance coverage needs to be provided to any Company or Buyer with respect to the properties and assets of the Companies under any insurance policy issued to Seller or any Affiliate of Seller (other than a Company) and (b) no Claims regarding any matter whatsoever, whether or not arising from events occurring prior to the Effective Time, shall be made by Buyer or its Affiliates (including any Company) directly against or under any of such insurance policies, regardless of their date of issuance.

3.3 Access.

(a) From and after the Execution Date and up to and including the Closing Date (or earlier termination of this Agreement), but subject to the other provisions of this Section 3.3 and obtaining any required consents of Third Parties, including Third Party operators of the Assets (which consents Seller shall use its commercially reasonable efforts to cause the Companies to obtain, but neither Seller nor any Company shall be required to pay any consideration therefor), Seller shall afford (and cause each Company to afford) to Buyer and its Representatives, upon reasonable prior notice, reasonable access, during normal business hours, to the Assets and all Records in Seller’s, the Companies’ or any of their Affiliates’ possession. All investigations and due diligence conducted by Buyer and its Representatives shall be conducted at Buyer’s sole cost, risk and expense, and any conclusions made from any examination done by Buyer or its Representatives shall result from Buyer’s own independent review and judgment. Buyer shall coordinate such access rights and physical inspections of the Assets with Seller so as not to unreasonably interfere with the conduct of business by Seller, any Company or the operator of the Assets. Buyer shall, and shall cause its Representatives to, abide by Seller’s and any Third Party operator’s applicable safety rules, regulations and operating policies (provided to Buyer in advance in writing) while conducting its due diligence evaluation of the Assets, including any environmental or other inspection or assessment of the Assets. Seller or its designee shall have the right to accompany Buyer or its Representatives whenever they are on site on the Assets.

(b) Buyer shall be entitled to conduct a Phase I environmental property assessment with respect to the Oil and Gas Properties and the Gathering Systems, but notwithstanding anything in this Section 3.3 to the contrary, (i) no Invasive Activity shall be conducted by Buyer or its Representatives upon the Oil and Gas Properties, the Gathering Systems or any other Assets without the prior written consent of Seller; provided, however, in the event that (x) Buyer’s Phase I has identified any actual “Recognized Environmental Conditions” (as such conditions are defined or described under the current American Society for Testing and Material Standard Practice Designation E1527-13) and Buyer’s consultant recommends an Invasive Activity to further evaluate such Recognized Environmental Conditions, (y) Buyer has delivered a written notice to Seller, setting forth Buyer’s plans for conducting such Invasive Activity (including the identity of the consultant who will conduct such Invasive Activity) and requesting Seller’s consent to conduct such an Invasive Activity (including the corresponding portions of the Phase I identifying the Recognized Environmental Condition), and (z) Buyer has consented to the consultant selected to conduct such Invasive Activity and the plans with respect to conducting such Invasive Activity, such consent not to be unreasonably withheld, conditioned or delayed, then

9

Buyer shall be permitted to conduct such Invasive Activity, to the limited extent expressly set forth in such consultant recommendations and the plan, and (ii) none of Buyer or its Representatives shall have access to, have the right to review or otherwise be permitted to conduct any on-site inspection with respect to any Oil and Gas Properties or Gathering Systems where Seller or a Company does not have the authority to grant access to such Oil and Gas Properties and Gathering Systems.

(c) Buyer hereby releases, indemnifies, defends and holds harmless each of the operators of the Assets and the members of the Seller Group (including the Companies) from and against any and all Claims (including any injury, loss or damage arising out of such entry that may occur to any member of the Buyer Group), arising out of, resulting from or relating to any office visit, field visit, environmental property assessment or other due diligence activity conducted by Buyer or its Representatives with respect to the Assets, EVEN IF SUCH CLAIMS 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 A MEMBER OF THE SELLER GROUP, EXCEPTING ONLY CLAIMS TO THE EXTENT ACTUALLY RESULTING ON THE ACCOUNT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF A MEMBER OF THE SELLER GROUP OR SOLELY FROM THE MERE DISCOVERY BY BUYER OF PREVIOUSLY EXISTING CONDITIONS NOT CREATED OR EXACERBATED BY BUYER.

(d) Buyer agrees to promptly provide Seller, but no later than the Environmental Defect Claim Date, copies of all final environmental reports and environmental test results prepared prior to such date by Buyer and/or any of its Representatives which contain environmental data collected or generated prior to such date from Buyer’s environmental due diligence with respect to the Assets. None of Buyer, any of its Representatives or Seller shall be deemed by Seller’s receipt of such documents, or otherwise, to have made any representation or warranty, expressed, implied or statutory, as to the condition of the Assets or to the accuracy of said documents or the information contained therein. Buyer Group shall keep and maintain confidential (and not disclose to any other Person including any Governmental Authority, in whole or in part) pursuant to the terms of the Confidentiality Agreement any results of (or reports or other documents arising from) an environmental assessment of the Assets in accordance with the terms of the Confidentiality Agreement and shall prior to Closing use such results, reports or other documents arising therefrom solely for purposes of Buyer’s diligence.

(e) Upon completion of Buyer’s due diligence, Buyer shall, at its sole cost and expense and without any cost or expense to Seller or its Affiliates (including the Companies), (i) repair all damage done to the Assets (including the real property and other assets associated therewith) caused by Buyer’s or any of its Representatives’ due diligence and (ii) remove all equipment, tools or other property brought onto the Assets in connection with such due diligence. Any disturbance to the Assets (including the real property and other assets associated therewith) resulting from the due diligence investigation conducted by or on behalf of Buyer shall be promptly corrected by Buyer as provided for above.

10

(f) During all periods prior to the Closing that Buyer or any of its Representatives are on the Assets, Buyer shall maintain, at its sole expense and with insurers reasonably satisfactory to Seller (or the applicable Third Party operator, as applicable), policies of insurance of types and in amounts sufficient to cover the obligations and liabilities of Buyer under this Section 3.3. Coverage under all insurance required to be carried by Buyer under this Section 3.3(f) shall (i) be primary insurance, (ii) list the Seller Group as additional insureds, (iii) waive subrogation against the Seller Group and (iv) provide for not less than five days’ prior notice to Seller in the event of cancellation or modification of the policy or reduction in coverage. Upon request by Seller, Buyer shall provide evidence of such insurance to Seller prior to entering the lands underlying the Assets.

3.4 Confidentiality. Buyer acknowledges that, pursuant to its right of access to the Records and/or the Assets, Buyer shall become privy to confidential and other information of Seller and the Companies and that such information shall until the Closing occurs be held confidential by Buyer and its Representatives in accordance with the terms of the Confidentiality Agreement as if each had been a party to the Confidentiality Agreement (if not already a party thereto).

3.5 Disclaimers.

ARTICLE 4

ALLOCATION OF RESPONSIBILITIES AND INDEMNITIES

4.1 Buyer Acknowledgment of Obligations. Except to the extent (and only to the extent) that Seller is obligated to indemnify Buyer Group pursuant to Section 4.2 or as provided in any Transaction Document, Buyer expressly acknowledges that the Companies are responsible for, and, from and after Closing, neither the Companies nor Buyer shall have any recourse against Seller or the Seller Group for, the debts, Claims, Liabilities, Environmental Defects, plugging and abandonment obligations, litigation matters, commitments, duties and obligations of the Companies, including those arising under, related to or in connection with the ownership, operation, use or condition of the Assets and/or the business of the Companies, whether or not such debts, liabilities, commitments, duties or obligations arose or relate to periods of time prior to, on or after the Effective Time, but excluding, for the avoidance of doubt, any Seller Taxes.

4.2 Seller’s Indemnity Obligation. If Closing shall occur, then effective from and after the Closing Date, and subject to the limitations set forth in this Article 4, Seller agrees to defend, indemnify and hold Buyer Group (including, from and after the Closing, the Companies) harmless from and against (without duplication, including any downward adjustments to the Purchase Price) any and all Claims arising out of, resulting from or relating to:

(a) any breach by Seller of Seller’s representations or warranties set forth in Article 6, Article 7 or in the certificate delivered by Seller at Closing pursuant to Section 10.2(h);

(b) any breach by Seller of any of its covenants or agreements under this Agreement;

(c) any of the Retained Liabilities; and

(d) Seller Taxes;

13

provided, however, in no event shall Seller have any obligation to provide indemnification for any matters to the extent adjustments therefor are taken into account in the Preliminary Settlement Statement or the Final Settlement Statement.

4.3 Buyer’s and Companies’ Indemnity Obligation.

(a) If Closing shall occur, from and after the Closing Date, Buyer agrees to defend, indemnify and hold Seller Group harmless from and against (without duplication, including any upward adjustments to the Purchase Price) any and all Claims arising out of, resulting from or relating to:

(i) any breach by Buyer of Buyer’s representations or warranties set forth in Article 8 or in the certificate delivered by Buyer at Closing pursuant to Section 10.1(h); and

(ii) any breach by Buyer of any of its covenants or agreements under this Agreement.

(b) Without limiting Buyer’s rights to indemnification pursuant to Section 4.2 and taking into account, and without duplication of, (i) Purchase Price adjustments pursuant to Section 2.3, Section 2.4 or Section 2.5, as applicable, and (ii) any payments made from one Party to the other in respect of Asset Taxes pursuant to Section 9.3(e), if Closing should occur, from and after the Closing, each Company agrees to defend, indemnify and hold Seller Group harmless from and against (without duplication, including any upward adjustments to the Purchase Price) any and all Claims of Third Parties arising out of, resulting from or relating to the ownership, use, operation, or condition of the Assets of such Company, directly or indirectly, by such Company, whether or not such Liabilities relate to periods prior to, on or after the Effective Time (including Liabilities incurred by Seller or its Affiliates with respect to any required payments under any guarantees (or replacements thereof) described on Schedule 9.11(b)), but excluding, in each case, any and all Claims related to or arising out of any Operating Expenses (other than Burdens) attributable to (i) the Assets for any periods of time prior to the Effective Time and (ii) all Excluded Assets.

4.4 Limitations on Liability. Seller shall have no obligation or Liability under Section 4.2(a), for:

(a) any Claim asserted by Buyer under Section 4.2(a), if such Claim has a value of $175,000 or less (the “Threshold Amount”) (and these types of Claims shall not be counted in determining whether the Indemnity Deductible has been reached);

(b) any Claim asserted by Buyer under Section 4.2(a), if the aggregate amount of all Claims asserted by Buyer under Section 4.2(a), that are in excess of the Threshold Amount does not exceed the Indemnity Deductible, and then only to the extent such Claims exceed the Indemnity Deductible; and

(c) any Claims asserted by Buyer under Section 4.2(a) to the extent exceeding, in the aggregate, 15% of the unadjusted Purchase Price.

14

Notwithstanding the foregoing, the limitations described above in Section 4.4(a)-(c) shall not apply to any Claim under Section 4.2(a) for breach of any of the Fundamental Representations or the representations and warranties set forth in Section 7.4, Section 7.32, Section 7.33 or Section 7.37; provided that Seller’s total liability for all Claims asserted by Buyer under this Agreement, including for a breach of any of the Fundamental Representations, shall not exceed 100% of the unadjusted Purchase Price.

4.5 Notice of Claims. All claims for indemnification under this Agreement shall be asserted and resolved as follows:

(a) For purposes of this Agreement, the term “Indemnifying Party” when used in connection with particular Claims shall mean the Party having an obligation to indemnify another Party or Person(s) with respect to such Claims pursuant to this Agreement, and the term “Indemnified Party” when used in connection with particular Claims shall mean the Party or Person(s) having the right to be indemnified with respect to such Claims by another Party pursuant to this Agreement.

(b) To make a claim for indemnification under this Agreement, an Indemnified Party shall notify the Indemnifying Party of its claim under this Section 4.5, 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 4.5 shall not relieve the Indemnifying Party of its obligations under this Agreement, except to the extent (and then only to such 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 on or before the 30th day after its receipt of the Claim Notice may notify the Indemnified Party whether the Indemnifying Party admits or denies its liability to indemnify and defend 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. In the event that the Indemnifying Party fails to notify the Indemnified Party on whether it admits or denies its liability to defend the Indemnified Party, then the Indemnifying Party shall be deemed to have denied such liability.

15

(d) If the Indemnifying Party assumes the defense of the Indemnified Party against a Third Party Claim, then the Indemnifying Party shall have the right and obligation to diligently defend, at its sole cost and expense, such Third Party Claim subject to the remaining provisions of this Section 4.5(d), provided that, any such Indemnifying Party may reserve the right to simultaneously dispute whether it is required to indemnify such Third Party Claim pursuant to this Agreement. If the Indemnifying Party so assumes the defense, 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 Party shall cooperate in contesting any Third Party Claim that the Indemnifying Party elects to contest. The Indemnified Party may participate in, at its own expense, but subject to the Indemnifying Party’s full control of, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 4.5(d); provided, however, that the Indemnified Party shall not be required to bring any counterclaim or cross complaint against any Person. 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 that does not include an unconditional written release of the Indemnified Party from all Claims 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 assume the defense of the Third Party Claim, initially assumes the defense of the Third Party Claim but is later determined (whether by agreement with the Indemnified Party or through resolution of a dispute over liability) to be not responsible for such indemnification obligation, or assumes the defense but fails to diligently prosecute 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 its 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. Any settlement of the Third Party Claim by the Indemnified Party shall require the consent of the Indemnifying Party (which shall not be unreasonably withheld, conditioned or delayed), unless the settlement is solely for money damages and results in a final resolution.

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

(g) Notwithstanding the above, the control and conduct of any Tax Audit that is a Third Party Claim shall be governed by Section 9.3(i).

4.6 Waiver of Certain Damages. NO MEMBER OF THE BUYER GROUP OR SELLER GROUP SHALL BE ENTITLED TO RECOVER FROM SELLER OR BUYER (RESPECTIVELY), OR THEIR RESPECTIVE AFFILIATES, ANY CONSEQUENTIAL, INDIRECT, INCIDENTAL, PUNITIVE, EXEMPLARY, REMOTE OR SPECULATIVE DAMAGES OF ANY KIND ARISING UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, EXCEPT TO THE EXTENT THAT (a) ANY DAMAGES FOR LOST PROFITS ARE DETERMINED BY A COURT TO BE DIRECT DAMAGES OR (b) ANY SUCH PARTY IS LIABLE TO PAY ANY

16

OF THE FOREGOING DAMAGES TO A THIRD PARTY, WHICH DAMAGES (INCLUDING COSTS OF DEFENSE AND REASONABLE ATTORNEY FEES INCURRED IN CONNECTION WITH DEFENDING AGAINST SUCH DAMAGES) SHALL NOT BE EXCLUDED BY THIS PROVISION AS TO RECOVERY HEREUNDER. SUBJECT TO THE PRECEDING SENTENCE, AND EXCEPTING THE DAMAGES DESCRIBED IN SUBPOINTS (a) AND (b) IN SUCH SENTENCE, BUYER, ON BEHALF OF EACH MEMBER OF THE BUYER GROUP, AND SELLER, ON BEHALF OF EACH MEMBER OF THE SELLER GROUP, WAIVE ANY RIGHT TO RECOVER CONSEQUENTIAL, INDIRECT, INCIDENTAL, PUNITIVE, EXEMPLARY, REMOTE OR SPECULATIVE DAMAGES OF ANY KIND (OTHER THAN DAMAGES FOR LOST PROFITS THAT ARE DETERMINED BY A COURT TO BE DIRECT DAMAGES) ARISING IN CONNECTION WITH OR WITH RESPECT TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

4.7 Exclusive Remedy. Notwithstanding anything to the contrary contained in this Agreement, from and after Closing, and except in the case of Fraud, Section 2.5, Section 3.2, 3.3(c), Section 4.2, Section 4.3, Section 5.2(d), Section 5.2(e), Section 5.3(b) and Section 9.14 contain the exclusive remedies of (a) Seller against Buyer, Valorem Energy LLC and any subsidiaries of Valorem Energy LLC and (b) Buyer against Seller and any Affiliates of Seller in each case with respect to the transactions contemplated hereby, including any breaches of the representations, warranties, covenants and agreements of the Parties contained in this Agreement and the affirmations of such representations, warranties, covenants and agreements contained in the certificate(s) delivered by each Party at Closing pursuant to Section 10.1(h) or Section 10.2(h), as applicable. Except in the case of Fraud and for the remedies contained in Section 2.5, Section 3.2, 3.3(c), Section 4.2, Section 4.3, Section 5.2(d), Section 5.2(e), Section 5.3(b) and Section 9.14, from and after Closing, Buyer (on its own behalf and on behalf of the other members of the Buyer Group) releases, remises and forever discharges Seller and its Affiliates and all of the other members of the Seller Group from any and all Claims at Law or in equity, known or unknown, that any member of the Buyer Group might now or subsequently may have, based on, relating to or arising out of this Agreement or the transactions contemplated hereby, the ownership of the Interests, the ownership, use or operation of the Assets, or the condition, quality, status or nature of the Assets, including rights to contribution under CERCLA, breaches of statutory or implied warranties, nuisance or other tort actions, rights to punitive damages, common law rights of contribution and rights under insurance maintained by Seller or any of its Affiliates.

4.8 Express Negligence. EXCEPT AS OTHERWISE PROVIDED IN SECTION 3.3(c), THE INDEMNIFICATION, RELEASE, WAIVER AND LIMITATION OF LIABILITY PROVISIONS PROVIDED FOR IN THIS AGREEMENT SHALL BE APPLICABLE WHETHER OR NOT THE CLAIMS, LIABILITIES, LOSSES, COSTS, EXPENSES AND DAMAGES IN QUESTION AROSE OR RESULTED SOLELY OR IN PART FROM THE GROSS, SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OR VIOLATION OF LAW OF OR BY ANY INDEMNIFIED PARTY. BUYER AND SELLER ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS.

17

4.9 Waiver of Right of Rescission. Seller and Buyer acknowledge that, subject to any express rights the Parties may have hereunder to seek and obtain specific performance or other equitable remedies, following Closing, the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant or agreement contained herein or for any other claim arising in connection with or with respect to the transactions contemplated by this Agreement. As such, Buyer and Seller waive any right to rescind this Agreement or any of the transactions contemplated hereby.

4.10 Insurance; Mitigation. The amount of any Claims for which any Indemnified Party is entitled to indemnification under this Agreement or in connection with or with respect to the transactions contemplated by this Agreement, shall be reduced by any corresponding insurance proceeds, from insurance policies carried by such Indemnified Party or its Affiliates, that are realized by such Indemnified Party from Third Party insurers with respect to such Claims; provided, that the Indemnified Party shall use commercially reasonable efforts to seek such insurance proceeds or indemnity, contribution or similar payments related to such Claims. If any Indemnified Party receives such insurance proceeds or indemnity, contribution or similar payments after the settlement of any indemnification claim under Section 4.2 or Section 4.3, as applicable, such Indemnified Party shall refund to the Indemnifying Party the amount of such insurance proceeds or indemnity, contribution or similar payments, up to the amount received in connection with such indemnification claim. It is the intention of the Parties that no insurer or Third Party shall be entitled to any benefit or right it would not be entitled to receive in the absence of this subsection. For the avoidance of doubt, in connection with any breach of the representations of Seller in Section 7.24(a), Buyer shall be required to use commercially reasonable efforts to mitigate all Liabilities resulting from such breach, including by rerouting any affected Hydrocarbons on other portions of the Gathering System with available capacity where it is commercially reasonable for Buyer to do so.

4.11 Indemnity Claim Deadlines.

(a) Seller shall be liable for:

(i) an alleged breach of a representation or warranty in Article 6, Article 7 or the certificate delivered by Seller at Closing pursuant to Section 10.2(h) (other than the Fundamental Representations or the representations and warranties set forth in Section 7.4, Section 7.8(d), Section 7.32, Section 7.33 or Section 7.37) only if Buyer (or an Indemnified Party, if applicable) has notified Seller of a claim for indemnification before the date that is 12 months after the Closing Date;

(ix) a claim for indemnification under Section 4.2(d), only if Buyer (or an Indemnified Party, if applicable) has notified Seller of a claim for indemnification before the date that is thirty days after the expiration of the statute of limitations applicable to the Claims subject to such indemnification.

Seller or Buyer may elect to exercise or not exercise indemnification rights hereunder on behalf of the other Indemnified Parties affiliated with it in its sole discretion and shall have no liability to any such other Indemnified Party for any action or inaction hereunder.

(c) The representations, warranties and covenants of each of the Parties set forth in this Agreement, subject to the express exceptions thereto, shall not be affected by any information furnished to, or any investigation or audit conducted before or after the Closing Date by, any Person in connection with the transactions contemplated hereby.

20

ARTICLE 5

TITLE MATTERS; ENVIRONMENTAL MATTERS

5.1 General Disclaimer of Title Warranties and Representations; Exclusive Remedy. Without limiting Buyer’s right to terminate this Agreement or Buyer’s remedies, as expressly set forth in Article 4 and this Article 5, except with respect to Section 7.18, Section 7.19, Section 7.32, Section 7.37, Section 9.1(b)(i), Section 9.1(c)(iv), Section 9.1(c)(xii) or Section 9.1(c)(xix) (a) Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to the Companies’ title to any of the Oil and Gas Properties, (b) Buyer hereby acknowledges and agrees that, except with respect to any Fraud by any member of the Seller Group or any Claim for breach of Section 7.18, Section 7.19, Section 7.32, Section 7.37, Section 9.1(b)(i), Section 9.1(c)(iv), Section 9.1(c)(xii) or Section 9.1(c)(xix), Buyer’s sole and exclusive remedy for any defect in title or any other title matter (including any Title Defect with respect to any of the Oil and Gas Properties or otherwise) shall be as set forth in Section 5.2 and (c) Buyer hereby expressly waives any and all other rights or remedies with respect thereto.

5.2 Title Defects.

(a) Title Defect Notices. On or before the Title Defect Claim Date, Buyer may deliver claim notices to Seller meeting the requirements of this Section 5.2(a) (collectively, the “Title Defect Notices,” and each individually, a “Title Defect Notice”) setting forth any matters that, in Buyer’s reasonable opinion, constitute Title Defects. Except with respect to a Claim for breach of Section 7.18, Section 7.19, Section 7.32, Section 7.37, Section 9.1(b)(i), Section 9.1(c)(iv), Section 9.1(c)(xii) or Section 9.1(c)(xix), for all purposes of this Agreement and notwithstanding anything herein to the contrary, Buyer shall be deemed to have waived, and none of Seller or any of its Affiliates or any other member of the Seller Group shall have any Liability for any Title Defect or any other title matter related to the Oil and Gas Properties that Buyer fails to properly assert as a Title Defect by a Title Defect Notice received by Seller on or before the Title Defect Claim Date. To be effective, each Title Defect Notice shall be in writing and shall include: (i) a description of the alleged Title Defect(s), (ii) the Assets affected by the alleged Title Defect(s) (each a “Title Defect Property”), (iii) the Allocated Value of each Title Defect Property, (iv) supporting documents reasonably necessary for Seller to identify the basis of the alleged Title Defect(s) and (v) the amount by which Buyer reasonably believes the Allocated Value of each Title Defect Property is reduced by the alleged Title Defect(s) and the computations (in reasonable detail) upon which Buyer’s belief is based. To give Seller an opportunity to commence reviewing and curing any Title Defects, Buyer agrees to use its commercially reasonable efforts to give Seller weekly written notices of all alleged Title Defects discovered by Buyer during the preceding weekly period after the Execution Date and prior to delivery of such notice, which notice may be supplemented on or prior to the Title Defect Claim Date; provided, however, that Buyer’s right to assert a Title Defect shall not be prejudiced by any failure to provide such advance notice.

(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 a notice meeting the requirements of this Section 5.2(b) (collectively, the “Title Benefit Notices,” and each individually, a “Title Benefit Notice”) setting forth any matters that, in Seller’s reasonable opinion, constitute Title Benefits. To be effective, each Title Benefit Notice shall be in writing and shall include: (i) a description of the

21

alleged Title Benefit(s), (ii) the Assets affected by the Title Benefit(s) (each a “Title Benefit Property”), (iii) the Allocated Value of each Title Benefit Property, (iv) supporting documents available to Seller reasonably necessary for Buyer to identify the basis of the alleged Title Benefit(s) and (v) the amount by which Seller reasonably believes the Allocated Value of each Title Benefit Property is increased by the alleged Title Benefit(s) and the computations (in reasonable detail) upon which Seller’s belief is based. Seller shall be deemed to have waived, and Buyer shall not have any Liability for, any Title Benefit that Seller fails to assert as a Title Benefit by a Title Benefit Notice received by Buyer on or before the Title Defect Claim Date. For clarity, Seller shall not be entitled to a Title Benefit or any remedies with respect to a Title Benefit Amount with respect to any Asset for which the Allocated Value is $0.

(c) Seller’s Right to Cure. Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure, at any time prior to the 120^th day after the Title Defect Claim Date (the “Title Cure Period”), any Title Defects of which it has timely received a Title Defect Notice from Buyer. During the period of time from Closing to the expiration of the Title Cure Period, Buyer agrees to afford (and cause the Upstream Company to afford), at no cost to Buyer, any Company or any of their respective Affiliates, Seller and its officers, employees and other authorized representatives reasonable access, during normal business hours, to the Records in Buyer’s or any of its Affiliates’ possession or control, together with a right to copy such Records at Seller’s sole cost, in order to facilitate Seller’s attempt to cure any such Title Defects.

(d) Remedies for Title Defects. Subject to (i) Seller’s continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto, (ii) the rights of Seller pursuant to Section 12.1(d), (iii) Section 5.2(h), and (iv) Seller’s cure rights pursuant to Section 5.2(c), if any Title Defect properly asserted by Buyer in accordance with Section 5.2(a) is not waived in writing by Buyer prior to the Closing, then at the Closing, the Purchase Price shall be reduced by an amount determined pursuant to Section 5.2(f) as being the value of such Title Defect to the extent affecting the applicable Title Defect Property (the “Title Defect Amount”).

(e) Remedies for Title Benefits. If any Title Benefits are timely asserted for a Well or Future Well by Seller in accordance with Section 5.2(b), then the applicable Title Benefit Amount shall be applied as set forth in Section 5.2(h). Seller hereby acknowledges and agrees that Seller’s sole and exclusive remedy for any Title Benefit or other title benefit shall be as set forth in Section 5.2 and Seller hereby expressly waives any and all other rights or remedies with respect thereto.

(f) Title Defect Amount. The Title Defect Amount resulting from a Title Defect shall be the amount by which the aggregate Allocated Values of the affected Title Defect Property(ies) is reduced as a result of the existence of such Title Defect and shall be determined in accordance with the following terms and conditions:

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

22

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

(iii) if the Title Defect represents a decrease in the Net Revenue Interest for the Target Formation of any Title Defect Property from the Net Revenue Interest set forth in Exhibit A-2 or Exhibit A-3, as applicable, for such Title Defect Property, and the Working Interest for the Target Formation of such Title Defect Property is reduced proportionately, then the Title Defect Amount shall be the product of the Allocated Value of such Title Defect Property, multiplied by a fraction, (A) the numerator of which is the amount of such Net Revenue Interest decrease and (B) the denominator of which is the Net Revenue Interest set forth for such Title Defect Property in Exhibit A-2 or Exhibit A-3, as applicable; provided that if the Title Defect does not affect the Title Defect Property throughout the entire life of such Title Defect Property, then the Title Defect Amount determined under this Section 5.2(f)(iii) shall be reduced to take into account the applicable time period only;

(iv) if the Title Defect represents an obligation or Encumbrance upon or other defect in title affecting the Title Defect Property of a type not described above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property, the values placed upon the Title Defect by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation;

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

(vi) notwithstanding anything to the contrary in this Article 5, 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.

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

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

(ii) if the Title Benefit represents an increase in the Net Revenue Interest for any Title Benefit Property such that the actual Net Revenue Interest for the Target Formation of any Title Benefit Property is greater than the Net Revenue Interest set forth in Exhibit A-2 or Exhibit A-3, as applicable, for such Title Benefit Property, and the Working Interest is unchanged or increased proportionately, then the Title Benefit Amount shall be the product of the Allocated Value of such Title Benefit Property, multiplied by a fraction, (A) the numerator of which is the amount of such Net Revenue Interest increase and (B) the denominator of which is the Net Revenue Interest set forth for such

23

Title Benefit Property in Exhibit A-2 or Exhibit A-3, as applicable; provided that if the Title Benefit does not affect the Title Benefit Property throughout the entire life of such Title Benefit Property, then the Title Benefit Amount determined under this Section 5.2(g)(ii) shall be reduced to take into account the applicable time period only; and

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

(h) Individual Title Threshold and Defect Deductible. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or any other remedy provided by Seller hereunder for any individual Title Defect for which the Title Defect Amount applicable thereto does not exceed the lesser of (x) $100,000 and (y) 50% of the aggregate Allocated Values of the affected Title Defect Properties (the “Individual Title Threshold”) and (ii) in no event shall there be any adjustments to the Purchase Price or any other remedy provided by Seller hereunder for any Title Defect for which the Title Defect Amount applicable thereto exceeds the Individual Title Threshold until (A) Title Defect Amounts of all such Title Defects that exceed the Individual Title Threshold, in the aggregate (excluding any Title Defect Amounts attributable to Title Defects cured by Seller during the Title Cure Period), less all Title Benefit Amounts that exceed the Individual Title Threshold, exceeds (B) the Title Defect Deductible, at which point Buyer shall only be entitled to remedies hereunder with respect to such amounts in excess of the Title Defect Deductible.

(i) Title Disputes.

(i) The Parties shall attempt, in good faith, to reach agreement on the existence of each Title Defect and Title Benefit, the value of each Title Defect and Title Benefit and the proper assertion of each Title Defect and Title Benefit by Title Defect Notice in accordance with Section 5.2(a) or Title Benefit Notice in accordance with Section 5.2(b), as applicable, prior to the Closing and on the adequacy of any cure of any Title Defect prior to the expiration of the Title Cure Period (collectively “Title Disputes”). If Seller and Buyer do not agree on any Title Dispute prior to such period, either Party shall have the right to elect, after the expiration of such period and upon written notice to the other Party, to initiate formal dispute resolution to resolve such Title Dispute(s) as are specified in such notice (collectively “Referred Title Disputes”). All Referred Title Disputes shall be exclusively and finally resolved pursuant to this Section 5.2(i). There shall be a single moderator, who shall be a title attorney with at least ten years’ experience in oil and gas titles involving properties in the state of Arkansas (the “Title Referee”). The Title Referee shall not have worked as an employee or outside counsel for either Party or its Affiliates during the 10-year period preceding the Effective Time or have any financial interest in the dispute or any other interest, position or relationship that would or might conflict with the proper performance of his or her duties as Title Referee. The Title Referee shall be selected by mutual agreement of Seller and

24

Buyer on or before the 15th day after the election of a Party to utilize the provisions of this Section 5.2(i) with respect to a Referred Title Dispute, provided that, in the event the Parties are unable to mutually agree upon the Title Referee within such time period, then either Party may petition the Houston, Texas office of the AAA to select the Title Referee. In connection with the engagement of the Title Referee, each Party shall execute such engagement, indemnity and other agreements as the Title Referee shall require as a condition to such engagement. Each Party shall submit in writing to the Title Referee, with a simultaneous copy to the other Party, a single written statement of its position on each Title Defect and Title Benefit subject to a Title Dispute, the Title Defect Amount or Title Benefit Amount, the compliance of Title Benefit Notice or Title Defect Notice with the requirements hereof or the adequacy of any cure of any Title Defect (each “Title Dispute Position”) together with a copy of this Agreement and any supporting material that such Party desires to furnish not later than the fifth Business Day after appointment of the Title Referee; provided that (except with respect to Buyer’s dispute of the adequacy of the cure of any Title Defect) Buyer’s Title Dispute Position shall be limited to only those positions identified in Buyer’s original Title Defect Notice. The Title Referee’s determination shall be made on or before the 30th day after submission of Referred Title Disputes and shall be final and binding upon both Parties, without right of appeal. In making his or her determination, the Title Referee shall be bound by the rules set forth in this Section 5.2 as applicable, and, subject to the foregoing, may consider such other matters as in the opinion of the Title Referee are necessary to make a proper determination; provided that the determination will be made solely on the Title Dispute Positions without any additional or supplemental submittals by either Party. Title Referee shall render a decision by choosing either Seller’s or Buyer’s Title Dispute Position with respect to each Referred Title Dispute, based on the materials described above that it deems the most closely conforms to the requirements of this Agreement. Each Party shall each bear its own legal fees and other costs of presenting its case to the Title Referee and shall each bear one half of the costs and expenses of the Title Referee. Buyer, with respect to Title Defects, and Seller, with respect to Title Benefits, shall be deemed to have conclusively waived any unresolved Title Defect, or cure thereof, or any unresolved Title Benefit which is not submitted for resolution as a Referred Title Dispute as provided in this Section on or before the 120th day after the end of the Title Cure Period.

(ii) To the extent that the award of the Title Referee with respect to any Title Defect Amount or Title Benefit Amount is not taken into account as an adjustment to the Purchase Price pursuant to Article 2, then on or before the tenth Business Day after the Title Referee delivers written notice to Buyer and Seller of its award with respect to a Title Defect Amount or a Title Benefit Amount and subject to Section 5.2(i), (A) Buyer shall pay to Seller the amount, if any, so awarded by the Title Referee to Seller and (B) Seller shall pay to Buyer the amount, if any, so awarded by the Title Referee to Buyer.

(iii) Nothing herein shall operate to cause the Closing to be delayed on account of any Title Dispute resolution hereunder and to the extent any adjustments for Title Defect validly submitted prior to the Closing are not agreed upon by the Parties as of the Closing, the Purchase Price shall be adjusted therefor as of the Closing based on Buyer’s good faith estimate for the same and subsequent adjustments thereto, if any, will be made pursuant to Section 2.5 or this Section 5.2(i).

5.3 Environmental Defects.

(a) Environmental Defect Notices. On or before the Environmental Defect Claim Date, Buyer may deliver claim notices to Seller meeting the requirements of this Section 5.3(a) (collectively, the “Environmental Defect Notices,” and each individually, an “Environmental Defect Notice”) setting forth any matters that, in Buyer’s reasonable opinion, constitute Environmental Defects. Except with respect to a Claim for the Retained Liabilities or a breach of Section 7.5, Section 7.7, Section 7.8, Section 7.22, Section 7.26 and Section 7.27 for all purposes of this Agreement and notwithstanding anything herein to the contrary, Buyer shall be deemed to have waived, and none of Seller or any of its Affiliates or any other member of the Seller Group shall have any Liability for, any Environmental Defect or any other environmental matter that Buyer fails to properly assert as an Environmental Defect by an Environmental Defect Notice received by Seller on or before the Environmental Defect Claim Date. To be effective, each Environmental Defect Notice shall be in writing and shall include: (i) a description of the matter constituting the alleged Environmental Defect (including the relevant Environmental Law implicated thereby), (ii) the Assets affected by the alleged Environmental Defect(s) (each an “Environmental Defect Property”), (iii) supporting documents reasonably necessary for Seller to identify the basis of the alleged Environmental Defect(s) and (iv) a calculation of the Remediation Amount (itemized in reasonable detail) that Buyer asserts is attributable to such alleged Environmental Defect. Buyer’s calculation of the Remediation Amount included in the Environmental Defect Notice should describe in reasonable detail the Remediation proposed for the asserted Environmental Defect and identify any significant assumptions used by Buyer in calculating the Remediation Amount, including the standards that Buyer asserts must be met to comply with Environmental Laws. To give Seller an opportunity to commence reviewing and curing any Environmental Defects, Buyer agrees to use its commercially reasonable efforts to give Seller written notices of all alleged Environmental Defects within ten (10) days of Buyer’s receipt of written notice confirming the existence of an Environmental Defect and prior to delivery of such notice, which notice may be supplemented on or prior to the Environmental Defect Claim Date; provided, however, that Buyer’s right to assert an Environmental Defect shall not be prejudiced by any failure to provide such advance notice. Seller shall at its sole discretion have the right, but not the obligation, to Remediate at Seller’s sole cost any claimed Environmental Defect during the Environmental Cure Period.

(b) Remedies for Environmental Defects. Subject to (x) Seller’s continuing right to dispute the existence of an Environmental Defect and/or the Remediation Amount asserted with respect thereto, (y) the rights of Seller pursuant to Section 12.1(d), and (z) Section 5.3(d), if any Environmental Defect properly asserted by Buyer in accordance with Section 5.3(a) is not waived in writing by Buyer or Remediated prior to Closing (the “Environmental Cure Period”), then at Closing, the Purchase Price shall be reduced by the Remediation Amount attributable to such Environmental Defect.

26

(c) Exclusive Remedy. Except for any Fraud by any member of the Seller Group, Buyer’s right to terminate this Agreement, Buyer’s remedies under Section 4.2(c) for Retained Liabilities or under Section 4.2(a) for the breach of Seller’s representations in Section 7.5, Section 7.7, Section 7.8, Section 7.22, Section 7.26 and Section 7.27, Section 5.3(a) shall be the exclusive right and remedy of Buyer with respect to any Environmental Defect or other environmental matter.

(d) Environmental Deductibles. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price for any Environmental Defect for which the Remediation Amount relating thereto is less than or equal to $100,000 (the “Individual Environmental Threshold”) and (ii) in no event shall there be any adjustments to the Purchase Price for any Environmental Defect for which the Remediation Amount(s) relating thereto exceeds the Individual Environmental Threshold unless the sum of the Remediation Amounts of all Environmental Defects that exceed the Individual Environmental Threshold, in the aggregate, exceed the Environmental Defect Deductible, at which point Buyer shall only be entitled to remedies hereunder with respect to such amounts in excess of the Environmental Defect Deductible.

(e) Environmental Defect Dispute.

(i) The Parties shall attempt, in good faith, to reach agreement regarding the existence of, nature of, or cost or adequacy of Remediation associated with any asserted Environmental Defect prior to the Closing Date or the proper assertion thereof in accordance with Section 5.3(a). If Seller and Buyer have not agreed on or before the Closing Date about the existence of an Environmental Defect or the cost or adequacy of Remediation associated with the asserted Environmental Defect or its proper assertion, then either Party shall have the right, after Closing and upon written notice to the other Party, to initiate formal dispute resolution to resolve such matters (collectively “Environmental Disputes”) as are specified in such notice. All Environmental Disputes shall be exclusively and finally resolved pursuant to this Section 5.3(e). There shall be a single moderator, who shall be a reputable environmental consultant or engineer with at least fifteen years’ experience in remedial and corrective environmental action regarding oil and gas properties (the “Environmental Referee”). The Environmental Referee shall not have worked as an employee or consultant for either Party or its Affiliates during the 10-year period preceding the Effective Time or have any financial interest in the dispute or any other interest, position or relationship that would or might conflict with the proper performance of his or her duties as Environmental Referee. The Environmental Referee shall be selected by mutual agreement of Seller and Buyer on or before the 15th day after the election of a Party to utilize the provisions of this Section 5.3(e) with respect to an alleged Environmental Defect, provided that, in the event the Parties are unable to mutually agree upon the Environmental Referee within such time period, then either Party may petition the Houston, Texas office of the AAA to select the Environmental Referee. In connection with the engagement of the Environmental Referee, each Party shall execute such engagement, indemnity and other agreements as the Environmental Referee shall require as a condition to such engagement. Each Party shall submit in writing to the Environmental Referee with a simultaneous copy to the other Party, a single written statement of its position on existence of the Environmental Defect and/or the cost or adequacy of Remediation associated with the asserted Environmental Dispute or the compliance of the Environmental Defect Notice with the requirements hereof (each

27

“Environmental Dispute Position”), together with a copy of this Agreement and any supporting material that such Party desires to furnish not later than the fifth Business Day after appointment of the Environmental Referee, provided that (except with respect to Buyer’s dispute of the adequacy of the cure of any Environmental Defect) Buyer’s Environmental Dispute Position shall be limited to only those positions identified in Buyer’s original Environmental Defect Notice. The Environmental Referee’s determination, as applicable, shall be made on or before the 30th day after submission of the matters in dispute and shall be final and binding upon the Parties, without right of appeal. In making its determinations, the Environmental Referee shall be bound by the provisions of this Section 5.3 and may consider such other matters as, in the opinion of the Environmental Referee, are necessary or helpful to make a proper determination; provided that the determination will be made solely on the Environmental Dispute Positions without any additional or supplemental submittals by either Party. The Environmental Referee may consult with and engage disinterested third persons to advise the Environmental Referee, including other environmental consultants. Environmental Referee shall render a decision choosing either Seller’s or Buyer’s Environmental Dispute Position with respect to each Environmental Dispute, based on the materials described above that it deems the most closely conforms to the requirements of this Agreement. The Environmental Referee may not award damages (except as represented by the value of an Environmental Defect), interest, or penalties to any Party with respect to any matter. Each Party shall each bear its own legal fees and other costs of presenting its respective case and shall each bear one half of the costs and expenses of the Environmental Referee. Buyer and Seller shall be deemed to have conclusively waived any unresolved Environmental Defects or cure thereof which is not submitted for resolution as an Environmental Dispute as provided in this Section on or before the 120th day after the Closing.

(ii) To the extent that the award of the Environmental Referee with respect to any Remediation Amount is not taken into account as an adjustment to the Purchase Price pursuant to Article 2, then on or before the tenth Business Day after the Environmental Referee delivers written notice to Buyer and Seller of his award with respect to a Remediation Amount and subject to Section 5.3(d), (A) Buyer shall pay to Seller the amount, if any, so awarded by the Environmental Referee to Seller and (B) Seller shall pay to Buyer the amount, if any, so awarded by the Environmental Referee to Buyer.

(iii) Nothing herein shall operate to cause the Closing to be delayed on account of any Environmental Dispute resolution hereunder and to the extent any adjustments are not agreed upon by the Parties as of the Closing, the Purchase Price shall be adjusted therefor as of the Closing based on Buyer’s good faith estimate for the same and subsequent adjustments thereto, if any, will be made pursuant to Section 2.5 or this Section 5.3(e).

(f) NORM, Wastes and Other Substances. Buyer acknowledges that the Assets have been used for exploration, development, production, gathering and transportation of oil and gas and there may be petroleum, produced water, wastes or other substances or materials located in, on or under the Assets or associated with the Assets. Equipment and sites included in the Assets may contain asbestos, NORM or other Hazardous Substances. NORM may affix or attach itself

28

to the inside of wells, pipelines, materials and equipment as scale, or in other forms. The wells, materials and equipment located on the Assets or included in the Assets may contain NORM and other wastes or Hazardous Substances. NORM containing material 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 environmental media, wastes, asbestos, NORM and other Hazardous Substances from the Assets. For the avoidance of doubt, NORM or asbestos containing materials shall not constitute the basis of an Environmental Defect or the basis of any breach of the representations contained in Section 7.5, Section 7.7, Section 7.8, Section 7.22, Section 7.26 and Section 7.27, except to the extent that Remediation of such NORM or asbestos containing materials is currently required under Environmental Laws.

9.2 Names. As soon as reasonably possible after the Closing, but in no event later than (a) the tenth (10^th) Business Day after Closing, Buyer shall change the name of the Companies to remove the names and other identifying marks of Seller and its Affiliates, including “Southwestern” and “SWN”, but excluding “DeSoto”, and (b) the one hundred twentieth (120^th)

49

day after Closing, Buyer shall remove “Southwestern” and “SWN” or other similar marks and any other related trademark, design or logo previously or currently used by any Company or any of its Affiliates, but excluding “DeSoto”, from all of the Assets acquired pursuant to this Agreement, including all buildings, signs and vehicles of such Company and cease using such mark in electronic databases, web sites, product instructions, packaging and other materials, printed or otherwise and otherwise cease making use of the word “Southwestern” or “SWN” for any purpose, but excluding “DeSoto”. As soon as reasonably possible after the Closing, Buyer shall make the requisite filings with, and provide the requisite notices to, the appropriate Governmental Authorities to accomplish the foregoing and to place the title or other indicia of ownership of the Assets in a name other than any name of Seller or any of its Affiliates, or any variations thereof. Buyer acknowledges and agrees that Seller is the owner of the “Southwestern” and “SWN” names and marks and all goodwill attached thereto, which are Excluded Assets, and Seller acknowledges that the Midstream Company Interests include any rights of the Midstream Company in the name “DeSoto.”

9.3 Tax Matters.

(a) Seller shall prepare or cause to be prepared and file or cause to be filed all Seller Consolidated Returns (including in each such Seller Consolidated Return, for the avoidance of doubt, any and all items and activities of the Companies through and including the Closing Date), and shall pay all Taxes owed with respect to such Seller Consolidated Returns.

(b) Seller shall be responsible for filing or causing to be filed with the applicable taxing authorities each Tax Return of the Companies (other than any Seller Consolidated Return) that is required to be filed on or before the Closing Date and paying or causing to be paid the Taxes reflected on such Tax Returns as due and owing.

(c) Except as otherwise provided in the Transition Services Agreement, Buyer shall be responsible for filing with the applicable taxing authorities each Tax Return with respect to Asset Taxes and Non-Asset Taxes of the Companies that is required to be filed after the Closing Date for any Tax period that ends before or includes the Closing Date, and paying the Taxes reflected on such Tax Returns as due and owing; provided, however, that in the event that Seller is required by applicable Law to file with the applicable Governmental Authority any such Tax Return and pay the Taxes reflected on such Tax Return, Seller shall file each such Tax Return on or prior to the due date therefor as prepared by Buyer, taking into account any reasonable comments Seller may have, and shall pay all Taxes reflected on such Tax Returns as due and owing.

(d) Seller shall be allocated and shall bear all Asset Taxes for any Tax period ending prior to the Effective Time and for the portion of any Current Tax Period ending immediately prior to the Effective Time, and Buyer shall be allocated and shall bear all Asset Taxes for any Tax period beginning after the Effective Time and for the portion of any Current Tax Period beginning at the Effective Time (ignoring, for purposes of this Section 9.3(d) that such Asset Taxes may be imposed on the Companies rather than on the Parties directly). For purposes of the foregoing:

(i) Asset Taxes that are attributable to the severance or production of Hydrocarbons (other than such Asset Taxes described in clause (iii)) shall be apportioned between the Parties based on the number of units actually produced before, on or after the Effective Time.

50

(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.

(iii) Asset Taxes that are ad valorem, property or other Asset Taxes imposed on a periodic basis pertaining to a Current Tax Period shall be allocated between the portion of such Current Tax Period ending immediately prior to the Effective Time and the portion of such Current Tax Period beginning at the Effective Time by prorating each such Asset Tax based on the number of days in the applicable Current Tax Period that occur before the date on which the Effective Time occurs, on the one hand, and the number of days in such Current Tax Period that occur on or after the date on which the Effective Time occurs, on the other hand.

(e) 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 Tax pursuant to Section 2.3, Section 2.4 or Section 2.5, as applicable, the Parties shall utilize the most recent information available in estimating the amount of such Asset Tax for purposes of such adjustment. To the extent the actual amount of an Asset Tax (or the amount thereof paid or economically borne by a Party) is ultimately determined to be different than the amount (if any) that was taken into account in the Final Settlement Statement as finally determined pursuant to Section 2.5, timely payments will be made from one Party to the other to the extent necessary to cause each Party to bear the amount of such Asset Tax that is allocable to such Party under Section 9.3(d).

(f) Seller shall be allocated and shall bear all Non-Asset Taxes for any Tax period ending on or prior to the Closing Date and the portion of any Current Tax Period ending on the Closing Date, and Buyer shall be allocated and shall bear all Non-Asset Taxes for any Tax period beginning after the Closing Date and the portion of any Current Tax Period beginning immediately after the Closing Date. For purposes of the foregoing, in the case of any Non-Asset Taxes that are payable with respect to any Current Tax Period, the portion of any such Non-Asset Taxes that is attributable to the portion of such Current Tax Period ending on the Closing Date shall be the amount that would be payable if the Current Tax Period ended with (and included) the Closing Date; provided, however, that with respect to any Arkansas franchise tax or any other Non-Asset Tax imposed on a periodic basis with respect to the assets or capital of any Company, the portion of such Non-Asset Taxes that is attributable to the portion of such Current Tax Period ending on the Closing Date shall be deemed to be the amount of such Taxes for the entire Current Tax Period, multiplied by a fraction the numerator of which is the number of calendar days in the portion of Current Tax Period ending on and including the Closing Date and the denominator of which is the number of calendar days in the entire Current Tax Period.

51

(g) Buyer and Seller 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 imposed on or with respect to the assets, operations or activities of any Company. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any such Tax Return or Tax proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.

(h) The amount of any refunds or credits of (i) Asset Taxes for any taxable period ending prior to the Effective Time and for the portion of any Current Tax Period ending immediately prior to the Effective Time, and (ii) Non-Asset Taxes and Income Taxes (other than Income Taxes that are Non-Asset Taxes)for any taxable period ending on or prior to the Closing Date and for the portion of any Current Tax Period ending on the Closing Date shall, in each case, be for the account of Seller. The amount of any refunds or credits of (x) Asset Taxes for any taxable period beginning at or after the Effective Time or the portion of any Current Tax Period beginning at the Effective Time, and (y) Non-Asset Taxes and Income Taxes (other than Income Taxes that are Non-Asset Taxes)for any taxable period beginning after the Closing Date and for the portion of any Current Tax Period beginning immediately after the Closing Date shall, in each case, be for the account of Buyer. The amount of any refunds or credits of any such Taxes for any Current Tax Period shall be equitably apportioned between Buyer and Seller in accordance with the principles set forth in Section 9.3(d) or 9.3(f), as applicable. Each Party shall forward, and shall cause its Affiliates to forward, to the Party entitled to receive a refund or credit of Tax pursuant to this Section 9.3(h) the amount of such refund or credit on or before the 30th day after such refund is received or such credit is recognized, in each case, net of any costs or expenses incurred by such Party or its Affiliates in procuring such refund or credit. Buyer shall take all necessary actions, or cause each Company to take all necessary actions, as are commercially reasonable, to obtain any such refunds or credits of Taxes of such Company for the account of Seller pursuant to this Section 9.3(h). For the avoidance of doubt, any refund of Taxes allocable to Seller under this Section 9.3(h) received by Buyer or the Companies in the form of a credit against future Taxes shall be for the account of Seller.

(i) After the Closing, except as otherwise provided in the Joint Defense Agreement, Buyer shall control the conduct of any audit, adjustment, claim, examination, assessment, contest, or other proceeding with respect to Asset Taxes and Non-Asset Taxes of the Companies (each a “Tax Audit”). In the case of a Tax Audit that relates to, or could reasonably be expected to give rise to, Seller Taxes, Seller, at its election, may control the conduct of such Tax Audit, and Seller shall not settle, compromise or concede any portion of such Tax Audit that is reasonably likely to affect Taxes of any Company for any Current Tax Period or any taxable year beginning at or after the Effective Time, or after the Closing Date, as applicable, without the consent of Buyer, which consent shall not be unreasonably withheld, delayed or conditioned. In the case of a Tax Audit that relates to, or could reasonably be expected to give rise to, Seller Taxes and that Seller does not elect to control, (i) Buyer shall control the conduct of such Tax Audit, shall use its commercially reasonable efforts to conduct such Tax Audit in a manner that is not likely to affect Seller Taxes, and shall not settle, compromise or concede any portion of such Tax Audit that is likely to affect Seller Taxes without the consent of Seller, which consent shall not be unreasonably withheld, delayed or conditioned, and (ii) Seller shall reimburse Buyer within 5 days after Buyer’s request therefor, for the product of (A) the reasonable out-of-pocket costs and expenses incurred by Buyer in conducting any such Tax Audit multiplied by (B) the percentage that the amount of Seller Taxes at issue in such Tax Audit bears to the total amount of Taxes at issue in such Tax Audit.

52

(j) The Parties agree that any payments made pursuant to Section 2.5, Article 4, Section 5.3(a) or this Section 9.3 shall be treated for all Tax purposes as an adjustment to the Purchase Price unless otherwise required by Law.

(k) Transfer Taxes (if any) incurred in connection with this Agreement and the transactions contemplated thereby will be borne one-half by Buyer and one-half by Seller. 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.

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

9.4 Amendment to Schedules. Seller shall have the right, exercisable until the Closing, to add, supplement or amend the Schedules applicable to its representations and warranties in Article 6 and Article 7 with respect to any matter hereafter arising or discovered that, if existing or known at the Execution Date or thereafter, would have been required to be set forth or described in such Schedules (each, a “Schedule Update”). For the purposes of determining whether Buyer has the right to terminate this Agreement pursuant to Section 12.1(b) or Section 12.1(d) and for purposes of the Buyer Indemnified Parties’ rights to indemnification under Article 4, such

53

Schedule Update shall not be deemed to cure any inaccuracy of any representation or warranty made in this Agreement, provided that, to the extent that Buyer has the right to terminate this Agreement pursuant to Section 12.1(b) or Section 12.1(d) as a result of such Schedule Update and Buyer does not exercise such right, and the Schedule Update pursuant to this Section 9.4 relates to any matter first arising or known after the Execution Date, then such Schedule Update shall be deemed to cure any inaccuracy of any representation or warranty made in this Agreement for all purposes hereunder.

9.5 Certain Notices. Between the Execution Date and the Closing Date, Seller shall give prompt written notice to Buyer if, to the Knowledge of Seller, there has been a breach of any of Buyer’s representations, warranties or covenants contained herein and Buyer shall give prompt written notice to Seller if, to the Knowledge of Buyer, there has been a breach of any of the representations, warranties or covenants of Seller contained herein. Notwithstanding anything in this Agreement to the contrary, this Section 9.4 shall not limit or otherwise affect Buyer’s indemnification rights under Section 4.2(d).

9.6 Bonds. Buyer acknowledges that none of the bonds, letters of credit and guaranties posted by Seller or its Affiliates (including the Companies) with a Governmental Authority or co-owners that relate to the Assets, including those set forth on Schedule 9.6, will be transferred to Buyer or the Companies. At or prior to the Closing, Buyer, at Buyer’s sole cost and expense, shall deliver to Seller evidence of the posting of replacements for all bonds, letters of credit and guaranties set forth on Schedule 9.6 to the extent such replacements are necessary to permit the cancellation of the bonds, letters of credit and guaranties posted by Seller or its Affiliates (including the Companies) set forth on Schedule 9.6. From and after the Closing, Buyer shall indemnify and hold Seller harmless from and against any and all Liabilities arising out of, based upon, attributable to or resulting from Buyer’s failure to replace such bonds, letters of credit and guaranties in accordance with this Section 9.6 and have all bonds, letters of credit and guaranties set forth on Schedule 9.6 posted by Seller or its Affiliates released.

9.7 Records. As soon as practicable, but in no event later than the 30th day after the termination of the Transition Services Agreement (except as provided below), Seller shall furnish to Buyer the Upstream Company Records and the Midstream Company Records that are maintained within the possession of Seller, any of the Companies or their Affiliates; provided, however, that Seller shall deliver or cause to be delivered to Buyer electronic records constituting customary Lease and Burden ownership and deck information, including owners numbers, addresses and tax identification numbers, data extraction of the burdened divisions of interest utilized in revenue and joint-interest-billing processes, data extraction of facilities and allocation cost centers, together with the information described on Schedule 9.7, in each case with respect to the Assets on or before the date that is fourteen Business Days after the Execution Date or as soon thereafter as reasonably practicable but in no event later than 45 days after the Execution Date; provided, further, that Seller (a) may retain copies of any or all Records subject to Section 9.21, and (b) may retain all Records (other than Records with respect to Tax matters) to the extent associated with any Excluded Assets. Notwithstanding the foregoing, Seller shall not be liable for any breach of this Section 9.7 in the event that it fails to furnish to Buyer any emails or any Records that are not material or necessary to the current conduct of the Business and that require unreasonable burden on Seller to produce, provided, further, that at any point during the term of

54

the Transition Services Agreement, upon request, Buyer shall be granted access to all such (i) emails sent to or from any Transferred Employee to the extent reasonably necessary to defend or prosecute any Third Party litigation arising prior to the two year anniversary of the Closing Date, and (ii) Records that were retained by Seller, and in each case, to the extent that such emails and Records are in Seller’s possession at the time of such request and do not create an undue burden on Seller to provide. Buyer shall maintain the Records that it acquires for a period of seven years after Closing and shall afford Seller reasonable access at Seller’s sole cost and expense to such Records as reasonably requested by Seller.

9.8 Excluded Assets. Prior to the Closing Date, Seller shall (at its sole cost and expense) cause each Company to convey (whether by assignment, spin-off, distribution, disbursement, dividend or otherwise) all of its right, title and interest in and to, and Seller shall assume all Claims and liabilities relating to, the Excluded Assets (including all Closing Date Cash and Cash Equivalents and Pre-Effective Time Receivables) to Seller or Seller’s designee pursuant to the Excluded Assets Assignment and/or other instrument as Seller and Buyer shall mutually determine.

9.9 Information Technology. Prior to the Closing, Seller shall be entitled to erase any data constituting or related to Excluded Assets or other assets or properties to the extent not related to the Assets, the Companies or the Business from any desktop, laptop, smart phone, tablet or other mobile computing device, network gear, data center gear and any other information technology equipment held by any Company.

9.10 HSR Act. If applicable, on or before the tenth Business Day following the Execution Date, Buyer and Seller will each prepare and simultaneously file with the DOJ and the FTC the notification and report form required for the transactions contemplated by this Agreement by the HSR Act and request early termination of the waiting period thereunder. Buyer and Seller agree to respond promptly to any inquiries from the DOJ or the FTC concerning such filings and to comply in all material respects with the filing requirements of the HSR Act. Buyer and Seller shall cooperate with each other and, subject to the terms of the Confidentiality Agreement, shall promptly furnish all information to the other Party that is necessary in connection with Buyer’s and Seller’s compliance with the HSR Act. Buyer and Seller shall keep each other fully advised with respect to any requests from or communications with the DOJ or FTC concerning such filings and shall consult with each other with respect to all responses thereto. Each of Seller and Buyer shall use its commercially reasonable efforts to take all actions reasonably necessary and appropriate in connection with any HSR Act filing to consummate the transactions consummated hereby. Buyer shall bear 100% of the filing fees of the HSR Act filings.

9.11 Firm Transportation Agreements.

(a) (i) Buyer shall prepare and file with FERC (and Seller shall, and shall cause the Companies and their respective Affiliates to cooperate with Buyer in connection therewith) a joint petition for temporary waivers (the “FERC Waivers”) of all applicable capacity release regulations and related policies and requirements and of the related tariff requirements of the interstate pipelines providing transportation service pursuant to firm transportation agreements as may be reasonably necessary to facilitate the assignment or permanent release from Seller, the Companies and their Affiliates to Buyer or its designated Affiliate of the contracts set forth on

Subject to applicable Laws, Buyer shall have the right to contact and have discussions with the applicable counterparties and beneficiaries of any bonds, letters of credit or guaranties to the extent reasonably necessary for Buyer to satisfy its obligations under this Section 9.11(b).

(c) Immediately following the Closing, Buyer shall cause the Upstream Company to execute and deliver to Seller transaction confirmations under the NAESB contracts set forth on Schedule 9.11(b) on terms and conditions set forth on Schedule 9.11(c).

9.12 Resignations of Officers and Managers. Effective upon the Closing, Seller shall cause (a) all powers of attorney on behalf of any Company, except as set forth in the Joint Defense Agreement, to be cancelled, (b) all of the directors, managers and officers of each Company, to resign and (c) each Company to terminate all bank accounts of any Company other than the Transferred Escrow Accounts.

9.13 Continuing Indemnification for Company Actors. From the Closing Date until the six (6) year anniversary date of the Effective Time, Buyer shall, and shall cause each Company to not amend, repeal or modify any of the obligations of each Company for indemnification and advancement of expenses in favor of each past and present holder of any Interest (including the ultimate beneficial owner or any Affiliate of an ultimate beneficial owner of interests), agent or other Representative, director, officer and manager of any Company (each, a “Company Indemnitee”) under the applicable Governing Documents of each Company (in effect as of the Execution Date), any indemnification agreements between any Company and any Company Indemnitee and any resolution of any Company or its managers or members in any manner that would adversely affect the rights thereunder of any such Company Indemnitee.

(a) The provisions of this Section 9.13 are intended to be for the benefit of, and will be enforceable by, each Company Indemnitee or insured Person, his or her heirs and his or her representatives and are in addition to, and not in substitution of, any other right to indemnification or contribution that any such Person may have by contract or otherwise. From the Closing Date until the six (6) year anniversary date of the Effective Time, in the event any Company or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving entity of such consolidation or merger or (ii) transfers

56

all or substantially all of its properties and assets to any Person, then, in each such case and as a condition precedent to such consolidation, merger or assignment, proper provisions shall be made so that the successors and assigns of such Company shall assume the obligations set forth in this Section 9.13.

9.14 Equitable and Other Remedies. Subject to Section 12.2, the Parties acknowledge and agree that the rights of each Party hereunder are special, unique and of extraordinary character, that the non-breaching Party or Parties would be irreparably and immediately harmed and would not have any adequate remedy at Law in the event that any provisions of this Agreement are not performed by the other Party or Parties or its or their Affiliates (as applicable) strictly in accordance with their respective terms or are otherwise breached, and it is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in each case, in accordance with the terms hereof. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief as provided herein on the basis that (a) either Party has an adequate remedy at Law or (b) an award of specific performance is not an appropriate remedy for any reason at Law or equity. Each Party further agrees that no Party shall be required to obtain, furnish or post any bond or similar instrument in connection with, or as a condition to, obtaining any remedy referred to in this Section 9.14, and each Party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS SECTION 9.14, THIS SECTION 9.14 SHALL ONLY APPLY TO THE COVENANTS AND AGREEMENTS OF THE PARTIES TO BE PERFORMED AFTER THE CLOSING, THE COVENANTS TO BE PERFORMED UNDER SECTIONS 3.4, 12.3 AND 13.9, AND THOSE SPECIFIC PERFORMANCE REMEDIES EXPRESSLY SET FORTH IN SECTION 12.2. Subject to Section 12.2, such remedy shall not be deemed to be the exclusive remedy for such breach of this Agreement but shall be in addition to all of the remedies at Law or in equity available to the non-breaching Party or Parties, subject, however, in each case, to Section 4.6.

9.15 Seller-Transferred Assets.

9.16 Employee Matters.

(a) Offers of Employment.

(i) Seller shall allow Buyer or its Affiliate to interview the Business Employees at reasonable times promptly following the Execution Date. The Parties shall cooperate in good faith to facilitate the Business Employee evaluation, meeting, and offer process contemplated by this Section 9.16. Any meetings or interviews between Buyer or its Affiliate and the Business Employees shall be

57

scheduled at times and places that are mutually agreed upon by Seller and Buyer, acting in good faith, with reasonable notice being provided by Buyer to Seller with respect to such times and places as Buyer proposes. Buyer or its Affiliate shall have no obligation to interview or make an offer of employment to any of the Business Employees. Following the Execution Date and prior to the applicable Hire Date, Seller shall inform Buyer of any Business Employee’s change in leave status and of any material disciplinary action taken with respect to any Business Employee. On or before October 31, 2018, Buyer or its Affiliate shall make offers to those Arkansas Business Employees of its choosing, and shall provide Seller, in writing, a list of those Arkansas Business Employees to whom Buyer or its Affiliate has made an offer of employment (collectively, the “Designated Arkansas Business Employees”). Such offers shall be for employment to be effective as of 12:01 a.m. on the Closing Date. Notwithstanding the foregoing, with respect to each Designated Arkansas Business Employee who is not actively employed due to an approved leave of absence as of immediately prior to the Closing Date (each, an “Inactive Designated Arkansas Business Employee”), such offers shall be (A) contingent on the circumstances being such that Seller or an Affiliate thereof would have been required to re-employ or continue to employ such Inactive Designated Arkansas Business Employee in accordance with its applicable policies, practices and procedures in effect on the date hereof, if the transactions contemplated by this Agreement had not occurred, and (B) for employment effective as of such date on which the applicable Inactive Designated Arkansas Business Employee returns from a leave of absence (so long as such return occurs within 90 days after the Closing Date or such later time as may be required by applicable Law). Buyer shall provide Seller, in writing, within ten (10) calendar days prior to the Closing Date, a list of those Designated Arkansas Business Employees who have accepted Buyer’s offer of employment and those Designated Arkansas Business Employees who have not successfully passed Buyer’s or its Affiliate’s applicable pre-employment screening requirements. Buyer shall update such list and provide such updated list to Seller on the day before the Closing and, if additional changes occur, on the Closing Date.

(ii) On or before October 31, 2018, Buyer or its Affiliates shall make all offers and shall provide Seller, in writing, a list of those Office Business Employees to whom Buyer or its Affiliate has made an offer of employment (collectively, the “Designated Office Business Employees” and, together with the Designated Arkansas Business Employees, the “Designated Business Employees”). Such offers shall be for employment to be effective as of 12:01 a.m. on the day immediately following the last day services are provided by the applicable Designated Office Business Employee pursuant to the Transition Services Agreement. Notwithstanding the foregoing, with respect to each Designated Office Business Employee who is not actively employed due to an approved leave of absence as of immediately prior to the Closing Date (each, an “Inactive Designated Office Business Employee”), such offers shall be (A) contingent on the circumstances being such that Seller or an Affiliate thereof would have been required to re-employ or continue to employ such Inactive Designated Office

58

Business Employee in accordance with its applicable policies, practices and procedures in effect on the date hereof, if the transactions contemplated by this Agreement had not occurred, and (B) for employment effective as of such date on which the applicable Inactive Designated Office Business Employee returns from a leave of absence (so long as such return occurs within 90 days after the last day services are provided by the applicable Designated Office Business Employee pursuant to the Transition Services Agreement or such later time as may be required by applicable Law). Buyer shall provide Seller, in writing, ten (10) calendar days prior to the Closing Date, a list of those Designated Office Business Employees who have accepted Buyer’s or its Affiliate’s offer of employment and those Designated Office Business Employees who have not successfully passed Buyer’s or its Affiliate’s applicable pre-employment screening requirements. Buyer shall update such list and provide such updated list to Seller on the day before the Closing and on the Closing Date, and shall thereafter promptly inform Seller of any updates to such list before the last day services are provided pursuant to the Transition Services Agreement.

(iii) Each Designated Business Employee who accepts an offer of employment from Buyer or its Affiliate, passes Buyer’s or its Affiliate’s applicable pre-employment screening requirements, and assumes employment with Buyer or its Affiliate is referred to herein as a “Transferred Employee.” The date of a Transferred Employee’s commencement of employment with Buyer or its Affiliate is referred to herein as his or her “Hire Date.” Effective as of 12:01 a.m. on the applicable Hire Date, Seller or an Affiliate thereof shall terminate the employment of the applicable Transferred Employee and each such Transferred Employee shall cease all active participation in and accrual of benefits under the Seller Benefit Plans. Nothing herein shall be construed as a representation or guarantee by Seller that any particular Designated Business Employee shall accept Buyer’s or its Affiliate’s offer of employment or shall continue in employment with Buyer or its Affiliates following the Closing.

(iv) All offers of employment by Buyer or its Affiliate to the Designated Business Employees shall be subject to and conditioned upon the occurrence of the Closing and the satisfaction of Buyer’s or its applicable Affiliate’s applicable pre-employment screening processes and made on terms and conditions sufficient to meet the requirements of this Section 9.16. Seller shall provide Buyer or its designated Affiliates three calendar years of bonus history for the Designated Business Employees.

(v) Seller and Buyer intend that the transactions contemplated by this Agreement, including the transfers of employment, shall not constitute a severance or termination of employment of any Transferred Employee prior to or upon the applicable Hire Date for purposes of any severance or termination benefit plan, program, policy, agreement or arrangement of Seller or any Affiliate thereof, and that Transferred Employees shall have continuous and uninterrupted employment immediately before and immediately after the applicable Hire Date.

59

(b) Comparability. With respect to each Transferred Employee, for the one-year period commencing on his or her applicable Hire Date and ending on the first anniversary of his or her applicable Hire Date, Buyer or its Affiliate shall provide each Transferred Employee with (i) a base salary or hourly base wage, as applicable, and target annual bonus opportunity that are not less than such Transferred Employee’s base salary or hourly base wage, as applicable, and target annual bonus opportunity provided by Seller or its Affiliate immediately prior to the Execution Date, (ii) employee benefits under each employee benefit plan, program or arrangement established or maintained by Buyer or its Affiliate (each, a “Buyer Benefit Plan”) that are no less favorable than the employee benefits provided to Buyer’s or its Affiliates’ similarly situated employees as of such Transferred Employee’s Hire Date and (iii) severance eligibility and other potential separation benefits (other than out placement services) that are no less favorable than the severance and other separation benefits provided by Seller or its Affiliates immediately prior to the Execution Date, which severance and other separation benefits are described in the Employee Notification.

(c) Severance Liabilities.

(i) With respect to each Business Employee that does not become a Designated Business Employee and each Designated Business Employee that does not accept an offer of employment from Buyer or its Affiliate made pursuant to this Section 9.16 (each, a “Non-Continuing Business Employee”), Seller shall be solely responsible for, and shall indemnify and hold harmless Buyer and its Affiliates from, all Liabilities that may result in respect of claims for severance or other separation benefits (whether statutory, contractual or common law) or other legally mandated payment obligations (including claims for wrongful dismissal, notice of termination of employment or pay in lieu of notice) with respect to each Non-Continuing Business Employee, together with the employer-paid portion of any employment or payroll taxes related thereto, arising out of, relating to or in connection with (i) Buyer’s or its Affiliates’ failure to offer employment to or continue the employment of any Non-Continuing Business Employee or (ii) the termination of employment of any Non-Continuing Business Employee; provided, however, that in the event that Buyer or any of its Affiliates breaches Section 9.16(m), Buyer shall promptly reimburse Seller for any and all Liabilities incurred by Seller and its Affiliates, if any, arising out of or with respect to the termination by Seller or its Affiliates of any Business Employee with respect to whom such breach has occurred (including any severance and other separation benefits paid by Seller or its Affiliates to such Business Employee, together with the employer-paid portion of any employment or payroll taxes related thereto). In furtherance of the foregoing, Buyer shall, within ten (10) days thereof, notify Seller of the hiring by Buyer or its Affiliates of any such Business Employee during the applicable period set forth in Section 9.16(m).

60

(ii) Buyer or its Affiliate shall be solely responsible for, and shall indemnify and hold harmless Seller from, all Liabilities that may result in respect of claims for severance or other separation benefits (whether statutory, contractual or common law) or other legally mandated payment obligations (including claims for wrongful dismissal, notice of termination of employment or pay in lieu of notice) with respect to each Transferred Employee, together with the employer-paid portion of any employment or payroll taxes related thereto, in each respect arising out of, relating to or in connection with Buyer’s or its Affiliate’s termination of employment of such Transferred Employee after his or her applicable Hire Date.

(d) Service Credit. From and after the applicable Hire Date of each Transferred Employee, Buyer or its Affiliate shall give or cause to be given to each Transferred Employee full credit for all purposes (including for purposes of eligibility to participate or receive benefits, vesting, benefit accrual, level of benefits and early retirement subsidies and including for purposes of severance, vacation/paid time off, layoff and similar benefits and for any purposes as may be required under applicable Law), other than for benefit accrual purposes under any defined benefit pension plan or vesting under any equity or incentive compensation plan or arrangement, under each employee benefit plan, program or arrangement established or maintained by Buyer or its Affiliate under which Transferred Employees are eligible to participate on or after the applicable Hire Date for service accrued or deemed accrued on or prior to the applicable Hire Date with Seller or any Affiliate thereof to the same extent that such credit was recognized by Seller or an Affiliate thereof under comparable Seller Benefit Plans immediately prior to the applicable Hire Date; provided, however, that such credit need not be provided to the extent that such credit would result in any duplication of benefits for the same period of service.

(e) Pre-Existing Conditions/Copayment Credit. With respect to each welfare benefit plan, program or arrangement maintained, sponsored or contributed to by Buyer or its Affiliates after the applicable Hire Date (collectively, the “Buyer Welfare Benefit Plans”) in which any Transferred Employee or spouse or dependent thereof may be eligible to participate on or after the applicable Hire Date, Buyer or its Affiliate shall (i) waive, or cause its Affiliates or insurance carrier to waive, all limitations as to preexisting conditions, actively-at-work requirements, exclusions and waiting periods, if any, with respect to participation and coverage requirements applicable to each Transferred Employee or spouse or dependent thereof, and any other restrictions that would prevent immediate or full participation by such Transferred Employee or spouse or dependent thereof, under such Buyer Welfare Benefit Plan, to the same extent satisfied or waived under a comparable Seller Benefit Plan, and (ii) provide or cause its Affiliates to provide full credit to each Transferred Employee or spouse or dependent thereof for any co-payments, deductibles, out-of-pocket expenses and for any lifetime maximums paid by such Transferred Employee or spouse or dependent thereof under the comparable Seller Benefit Plan during the relevant plan year up to and including the applicable Hire Date as if such amounts had been paid under such Buyer Welfare Benefit Plan.

(f) 401(k) Plan.

(i) If Buyer or its Affiliate shall have in effect at the Closing Date one or more defined contribution plans that include a qualified cash or deferred arrangement within the meaning of Section 401(k) of the Code (the “Buyer 401(k) Plan”), each Transferred Employee participating in a Seller Benefit Plan that is a

61

defined contribution plan that includes a qualified cash or deferred arrangement within the meaning of Section 401(k) of the Code (a “Seller 401(k) Plan”) immediately prior to the applicable Hire Date shall become eligible to participate in the corresponding Buyer 401(k) Plan as of the applicable Hire Date, and each Transferred Employee who would have become eligible to participate in the Seller 401(k) Plan shall become eligible to participate in the Buyer 401(k) Plan no later than such time as he or she would have become eligible to participate in the Seller 401(k) Plan.

(ii) Buyer or its Affiliate shall take all steps necessary to permit each Transferred Employee who has received an eligible rollover distribution (as defined in Section 402(c)(4) of the Code) from the Seller 401(k) Plan to roll over such eligible rollover distribution, including any associated loans, as part of a lump sum cash distribution into an account(s) under the Buyer 401(k) Plan.

(g) Vacation. For purposes of determining the number of vacation or annual leave days to which each Transferred Employee shall be entitled following his or her Hire Date, Buyer or its Affiliate shall assume and honor all vacation or annual leave days accrued or earned with Seller or its Affiliate but not yet taken by such Transferred Employee (and for which such Transferred Employee was not paid by Seller or its Affiliate) as of his or her Hire Date. To the extent that a Transferred Employee is entitled under any applicable Law or any policy of Seller or an Affiliate thereof to be paid for any vacation or annual leave days accrued or earned but not yet taken by such Transferred Employee as of his or her Hire Date, and such Transferred Employee does not elect to transfer such vacation or annual leave days accrued or earned but not yet taken to his or her employment with Buyer or its Affiliate, then Seller shall discharge the liability for such vacation or annual leave days.

(h) WARN Act and Other Notices. Buyer shall not take any action during the 90-day period following the Closing with respect to the Transferred Employees that would give rise to a “plant closing” or “mass layoff” under the WARN Act, whether standing alone or when aggregated with applicable pre-Closing “employment losses” (as defined under the WARN Act). Buyer agrees to provide, or to cause its Affiliates to provide, any required notice under the WARN Act and to otherwise comply with the WARN Act with respect to any “plant closing” or “mass layoff” or similar event affecting Transferred Employees (including as a result of the consummation of the transactions contemplated by this Agreement) and occurring on or after the Closing Date. Buyer shall assume liability for, and fully indemnify and hold harmless Seller and its Affiliates with respect to, any Liability incurred by Seller or any of its Affiliates pursuant to the WARN Act in connection with any Business Employee, to the extent such liability arises from actions of Buyer or any of its Affiliates on or after the Closing, including with respect to the actions described in the immediately preceding sentences. For the avoidance of doubt, Buyer’s agreement herein to assume Liability for, and to fully indemnify and hold harmless Seller and its Affiliates with respect to, any Liability incurred by Seller or any of its Affiliates pursuant to the Warn Act shall also apply to any Liability arising under the WARN Act due to any Business Employee’s termination or other employment loss resulting from the Buyer’s or its Affiliates’ failure to offer employment to such Business Employee.

62

(i) Employment Liabilities. Except as otherwise specifically provided in this Agreement, Seller shall retain responsibility for (i) all employment and employee benefits-related Liabilities that relate to the Business Employees (or any dependent or beneficiary of any Business Employee) under any Seller Benefit Plan or that arise with respect to the Business Employees as a result of an event or events that occurred prior to 12:01 a.m. on the applicable Hire Date of each such Business Employee, and (ii) any Liability that is or may be imposed on Midstream Company or Upstream Company due to such entity’s status as a current or former ERISA Affiliate of Seller. Effective as of 12:01 a.m. on the applicable Hire Date, Buyer or its Affiliate shall assume and be solely responsible for all employment and employee benefits-related Liabilities that relate to the Transferred Employees (or any dependent or beneficiary of any Transferred Employee) that arise as a result of an event or events that occurred on or after 12:01 a.m. on the applicable Hire Date.

(j) Employment Tax Reporting Responsibility. Seller and Buyer hereby agree to follow the standard procedure for employment tax withholding as provided in Section 4 of Rev. Proc. 2004-53, I.R.B. 2004-35. Accordingly, Seller or an Affiliate thereof shall have employment tax reporting responsibilities for the wages and other compensation it pays to Business Employees and Buyer shall have employment tax reporting responsibilities for the wages and other compensation it pays to Transferred Employees.

(k) Bonus for Year of Hire Date. Without limiting any other requirement set forth in this Section 9.16, Buyer or one of its Affiliates shall pay to each Transferred Employee who remains employed with Buyer or one of its Affiliates through December 31 of the calendar year in which such Transferred Employee’s Hire Date occurs, a prorated portion of such Transferred Employee’s annual cash bonus for such calendar year equal to (i) the target annual cash bonus opportunity for such Transferred Employee in effect with respect to the such calendar year under the applicable annual cash bonus program maintained by Seller or one of its Affiliates multiplied by (ii) a fraction, the numerator of which is the number of days in such calendar year from the applicable Hire Date through December 31 of such calendar year, and the denominator of which is 365 (such product of the foregoing clauses (i) and (ii), the “Prorated Bonus”). Seller or its Affiliates shall be responsible for any portion of the annual bonus payments made to the Transferred Employees for the calendar year in which the applicable Hire Date occurs in excess of the Prorated Bonus amounts, including the portion of the annual bonuses that relates to the portion of such calendar year up to and including the Hire Date (such amounts, the “Seller Bonuses” and, together with the Prorated Bonuses, the “Annual Bonuses”), and Seller shall reimburse Buyer or its designated Affiliate for such Seller Bonuses within 30 days of the date that such bonuses are paid to the Transferred Employees, in each case, provided that such Seller Bonuses are determined in a manner consistent with the annual bonus program maintained by Seller or its Affiliates for such Transferred Employee immediately prior to such Transferred Employee’s Hire Date. Buyer or its Affiliate shall pay the Annual Bonuses to the Transferred Employees no later than the time Seller or its Affiliate would have made such annual bonus payments to the Transferred Employees had such employees remained employed by Seller or its Affiliates but in no event later than March 15 of the calendar year following the calendar year in which the Hire Date occurs.

63

(l) No Third-Party Beneficiaries; No Guarantee of Employment. Notwithstanding anything in this Section 9.16 to the contrary, nothing contained herein, whether express or implied, shall be treated as an establishment, amendment or other modification of any Seller Benefit Plan or any employee benefit plan of Buyer or any of its Affiliates, or shall limit the right of Buyer or any of its Affiliates to amend, terminate or otherwise modify any Seller Benefit Plan or other employee benefit plan following the Closing Date. Seller and Buyer acknowledge and agree that all provisions contained in this Section 9.16 are included for their sole benefit, and that nothing in this Section 9.16, whether express or implied, shall create any third party beneficiary or other rights: (i) in any other Person, including any Business Employee, any participant in any Seller Benefit Plan or employee benefit plan of Buyer or any of its Affiliates, or any dependent or beneficiary thereof, or (ii) to continued employment with Buyer or any of its Affiliates or to any particular term or condition of employment.

(m) Non-Solicit. Buyer agrees that it will not, and it will cause the Companies not to, solicit for employment any Non-Continuing Business Employee for a period of one (1) year after the Closing Date without the prior written consent of the Seller except through advertisements of general circulation that are not specifically directed at such individuals.

9.17 Consents. If any Consent is not obtained prior to the Closing, Seller shall, subsequent to the Closing, reasonably cooperate with Buyer and such Company in attempting to obtain such consent, approval or authorization as promptly thereafter as practicable.

(a) With respect to each Consent set forth in any of the Schedules to this Agreement, Seller, within five (5) Business Days after the Execution Date, shall prepare and send, on forms reasonably satisfactory to Buyer, to the holder of each such Consent, including those set forth on Schedule 7.10, a notice in material compliance with the contractual provisions applicable to such Consent seeking such holder’s consent to the transactions contemplated by this Agreement. Seller shall use commercially reasonable efforts to cause any such Consents required to be obtained and delivered prior to Closing; provided that, Seller shall not be required to pay any amounts or incur any liabilities in connection with obtaining any such Consents. If Buyer or Seller discovers any Consent following the date hereof that is not set forth in any Schedule, Seller shall, (i) on or before the fifth (5th) Business Day after the date Seller becomes aware of such Consent, shall send to the holder of such Consent a notice in material compliance with the contractual provisions applicable to such Consent seeking such holder’s consent to the transactions contemplated by this Agreement and (ii) otherwise comply with such Consents in accordance with this Section 9.17.

(b) If Seller fails to obtain a Consent prior to the Closing and such Consent is a Hard Consent, then (A) Seller shall cause the applicable Company to convey the Assets subject to such Hard Consent to Seller or its designee (whether by assignment or dividend) in such reasonable manner as the Parties shall mutually determine, (B) such Asset(s) shall be characterized as Excluded Assets hereunder and (C) the Purchase Price shall be reduced at Closing by the Allocated Value, if any, of such Asset(s) (or portion thereof) so excluded. In the event that a Hard Consent

64

(with respect to an Asset for which there is a Purchase Price reduction pursuant to this Section 9.17(b)) that was not obtained prior to the Closing is obtained within one-hundred eighty (180 days) following the Closing, then, within ten (10) days after such Hard Consent is obtained, Buyer shall pay to Seller the amount by which the Purchase Price was reduced (and as otherwise adjusted herein) at the Closing with respect to the Asset (or portion thereof) so excluded, and Seller shall cause the execution and delivery of a conveyance transferring such affected Asset back to the applicable Company designated by Buyer.

9.18 FCC Filings. Each Party shall prepare, as soon as is practical following the Execution Date, any necessary filings in connection with the transactions contemplated by this Agreement that may be reasonably required or requested by any Governmental Authority under applicable Laws or a Party hereunder to be filed by such Party with the Federal Communications Commission with respect to transfer of the FCC Licenses. Any fees associated with the transfer of the FCC Licenses or payable to the Federal Communications Commission with respect to the transactions contemplated under this Agreement or the Transaction Documents shall be the sole responsibility of Buyer, and Buyer shall reimburse Seller for any such fees incurred by Seller or its Affiliates. The Parties shall promptly furnish each other with copies of any notices, correspondence or other written communication from the Federal Communications Commission, shall promptly make any appropriate or necessary subsequent or supplemental filings and shall cooperate in the preparation of such filings as is reasonably necessary and appropriate.

9.19 Financing; Cooperation. Seller acknowledges that Buyer may obtain debt financing (the “Financing”) to finance a portion of the Purchase Price. Buyer confirms that, subject to the completion of the Marketing Period, it is not a condition to Closing or any of its other obligations under this Agreement that Buyer obtain the Financing (or any other financing) for or in connection with the transaction contemplated by this Agreement. Prior to the Closing (or until the earlier termination of this Agreement in accordance the terms hereof), Seller shall provide, and shall use its commercially reasonable efforts to cause its Affiliates and its and their Representatives to provide, Buyer such reasonable cooperation as may be reasonably requested by Buyer with respect to the Financing, including (a) providing information reasonably requested by Buyer for its preparation of materials (including pro forma financial information) for bank information memoranda, marketing materials, and similar documents; (b) providing reasonable assistance to Buyer in preparing (i) a description of the Assets and “Management’s Discussion and Analysis” with respect to the Assets, (ii) the pro forma financial information and (iii) any other relevant section of any offering documents, in each case to the extent necessary in connection with any offering documents in respect of the Financing; (c) obtaining and providing customary reserve engineers’ and/or accountants’ comfort letters and consents; (d) furnishing Buyer and its Financing Sources with the Required Information as soon as reasonably practicable after request thereof by Buyer and taking into account the expected timing of the Marketing Period; (e) furnishing prior to the Closing Date, upon Buyer’s prior written request at least five (5) Business Days prior to the Closing Date, all documentation and other information required by Governmental Authorities under applicable “know your customer” and anti-money laundering rules and regulations, including the U.S.A. Patriot Act of 2001; and (f) facilitating Buyer’s preparation of the documentation necessary to pledge and mortgage the Assets that will be collateral under the Financing; provided, that, (i) none of the documents shall be executed and/or delivered except in connection with, or contingent upon, the Closing, (ii) the effectiveness thereof shall be conditioned

65

upon, or become operative after, the occurrence of the Closing and (iii) no liability shall be imposed on Seller or any Affiliate thereof or any of their respective officers or employees involved. In respect of Seller’s cooperation as set forth in this Section 9.19, in no event shall Seller or any Affiliate of Seller be required to pay any commitment or other fee or incur any other cost, expense, or liability in connection with the Financing that is not covered by the following indemnity (unless promptly reimbursed in accordance with this Section 9.19), and provided, further, that nothing herein will require such cooperation to the extent it unreasonably interferes with the business or operations of Seller or its Affiliates.

9.20 Termination of Intercompany Agreements and Intercompany Accounts. Except with respect to the Excluded Arrangements, prior to the Closing, Seller shall, and shall cause the Companies to, (i) pay, settle or discharge all account balances owed from any Company to any Related Party and (ii) terminate all Contracts between or among any Company, on the one hand, and any Related Party, on the other hand (and any Intercompany Agreement), in each case without any continuing Liability of any Company thereunder; provided that Seller shall notify Buyer in writing prior to terminating any such Contract not set forth on Schedule 7.34 and shall not terminate any such Contract until directed to do so by Buyer. Prior to the Closing, Seller shall deliver to Buyer written evidence reasonably satisfactory to Buyer of each such termination. For purposes of this Agreement, “Excluded Arrangements” means (i) any employment, severance or other similar arrangements with directors, officers or employees of the Companies (including, for the avoidance of doubt, any invention and non-disclosure, restrictive covenant or similar agreements), (ii) compensation for services performed by a Related Party as director, officer or employee of the Companies and amounts reimbursable for routine travel and other business expenses in the ordinary course of business consistent with past practices, (iii) the Transaction Documents, (iv) customer agreements entered into on arm’s-length terms in the ordinary course of business consistent with past practice and (v) the Contracts set forth on Schedule 9.20. At least three Business Days before Closing, Seller shall prepare and deliver to Buyer a statement setting out in reasonable detail the calculation of the Intercompany Account Balances, and, to the extent requested by Buyer, provide Buyer with supporting documentation to verify the underlying intercompany charges and transactions and such balances. All such Intercompany Account Balances shall be settled in full in cash and eliminated prior to Closing.

9.21 Confidentiality.

(a) From the Execution Date until the Closing Date, each Party shall keep confidential the Confidential Information in accordance with the terms of the Confidentiality Agreement. Notwithstanding the foregoing, nothing in this Section 9.21 shall restrict disclosures by any Party to the extent necessary to comply with such Party’s obligations under this Agreement. If the Closing occurs, then Buyer shall no longer be subject to the Confidentiality Agreement in so far as pertaining to Confidential Information pertaining to the Companies, the Assets or the Business.

Buyer agrees that, to the fullest extent permitted by Law, Buyer’s rights set forth in this Section 12.2(c) shall be the sole and exclusive remedy of Buyer if the Closing does not occur as a result of the termination of this Agreement pursuant to Section 12.1(b) or Section 12.1(e) in the circumstances described in this Section 12.2(c).
