Section 1 – Registrant’s Business and Operations



Item 1.01	Entry Into a Material Definitive Agreement

On November 16, 2018, QEP Resources, Inc. (the "Company"), through its wholly owned subsidiaries, QEP Energy Company, QEP Marketing Company, and QEP Oil & Gas Company (collectively, "Seller"), entered into a purchase and sale agreement (the "Purchase Agreement", and such sale transaction, the "Haynesville Divestiture") with Aethon III BR LLC ("Buyer"). The Purchase Agreement provides for the sale of natural gas and oil producing properties, undeveloped acreage and associated gas gathering and treating systems in the Haynesville/Cotton Valley located in Louisiana for an aggregate purchase price of $735.0 million, subject to purchase price adjustments, including adjustments for certain title and environmental defects asserted prior to the closing.

The Purchase Agreement provides that within two Business Days after the execution of the Purchase Agreement, the Buyer will deposit approximately $36.8 million (the "Escrow Amount") into an escrow account as a deposit to be applied against the purchase price at closing. The Haynesville Divestiture has an effective date of July 1, 2018. The Company and Seller expect to close the Haynesville Divestiture in the first quarter of 2019, subject to due diligence and the satisfaction of closing conditions.

Conditions to the Closing of the Haynesville Divestiture and Termination Rights

Before the closing of the Haynesville Divestiture, Buyer intends to conduct customary due diligence to assess the aggregate dollar value of any title and environmental defects, preferential purchase rights and certain consents. Except for its termination right, its remedy for a breach of Seller's special warranty of title and its remedy for a breach by Seller of certain limited representations, indemnifications and interim period covenants, Buyer’s exclusive remedy for title matters and environmental matters will be handled through a title or environmental defect mechanism.

Each party's separate obligation to consummate the Haynesville Divestiture is conditioned upon, among other things, (i) confirmation of the counterparty's representations and warranties as of the closing, (ii) the counterparty's performance, in all material respects, of all covenants, (iii) the absence of material legal matters prohibiting the Haynesville Divestiture, (iv) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, (v) delivery by the counterparty of a closing certificate, (vi) the counterparty being ready to deliver the closing deliverables, and (vii) the granting of the waivers by the Federal Energy Regulatory Commission (the "FERC") to facilitate the transfer of the firm transportation agreements from Seller to Buyer.

If the Purchase Agreement is terminated by Seller as a result of Buyer’s failure to consummate the Haynesville Divestiture at a time when Buyer’s conditions to closing have been satisfied, then, Seller will be entitled to receive the Escrow Amount and escrow earnings as liquidated damages. If the Purchase Agreement is terminated by Buyer as a result of Seller's failure to consummate the Haynesville Divestiture at a time when Seller’s conditions to closing have been satisfied, Buyer will be entitled to (i) receive the Escrow Amount and escrow earnings and seek to recover actual, direct damages up to but not exceeding the aggregate amount of the Escrow Amount and the escrow earnings, or (ii) seek specific performance of Seller to consummate the Haynesville Divestiture.

Others Terms of the Purchase Agreement

The Purchase Agreement contains customary representations, warranties and covenants for a transaction of this nature. The Purchase Agreement also contains customary mutual pre-closing covenants, including the obligation of Seller to conduct its business in all material respects in the usual, regular and ordinary manner consistent with its past practices and to refrain from taking certain specified actions, in each case with respect to the Haynesville Assets, without the consent of Buyer.

As part of the Haynesville Divestiture, Buyer has agreed to assume all firm gas transportation agreements related to the Haynesville Assets. In addition, Seller will novate natural gas derivative contracts covering approximately 40 BCF of gas for the last 11 months of 2019 to Buyer.

The foregoing is qualified in its entirety by reference to the full text of the Purchase Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

(s) except to the extent pertaining to any indemnity obligation paid by Seller hereunder or to the Excluded Assets, all claims, rights, demands, causes of action, suits, actions, judgments, damages, awards, recoveries, settlements, indemnities, warranties, rights to insurance proceeds, refunds, reimbursements, audit rights, duties, obligations, liabilities and other intangible rights in favor of or owed to Seller and either (i) relating to any Upstream Assumed Obligation or (ii) other than in connection with any matter for which, and solely to the extent which, Seller provides indemnity under Section 8.2, arising or attributable to the period of time from and after the Effective Time and related to any Upstream Asset described in clauses (a)-(r) above or the ownership or operation thereof, and, in each case, insofar and only insofar as such matters are not already applied as an adjustment to the Purchase Price;

(t) all JIB Receivables;

(u) the Conveyed Rights; and

(v) all (i) accounts receivable attributable to the Upstream Assets and periods of time from and after the Effective Time, other than any applicable JIB Receivables, and (ii) other rights of Seller to receive or recoup, by offset or netting against production from the Upstream Assets and the proceeds thereof, amounts owed by Persons other than Seller and its Affiliates with respect to the Upstream Assets whether attributable to periods of time prior to or from and after the Effective Time (the “Assigned Receivables”).

2.3 Upstream Excluded Assets. Upstream Seller shall reserve and retain, on its own behalf or on behalf of certain of its Affiliates, all of its and its Affiliates’ right, title and interest in and to the Excluded Assets.

2.4 Revenues and Expenses.

(a) For purposes of determining the amount of the adjustment to the Purchase Price provided for in Section 3.3, the principles set forth in this Section 2.4 shall apply except as expressly provided

otherwise in this Agreement. Subject to the preceding sentence, (i) Upstream Seller shall be entitled to all of the rights of ownership attributable to the Upstream Assets (including the right to all production, proceeds of production and other proceeds) and shall remain responsible for all Upstream Operating Expenses, in each case, attributable to the period of time prior to the Effective Time, and (ii) Midstream Seller shall be entitled to all of the rights of ownership attributable to the Midstream Interests and shall remain responsible for all Midstream Operating Expenses, in each case, attributable to the period of time prior to the Effective Time. Subject to the occurrence of the Closing, Buyer shall be entitled to all of the rights of ownership attributable to the Upstream Assets (including the right to all production, proceeds of production and other proceeds) and Midstream Interests, and shall be responsible for all Operating Expenses attributable thereto, in each case, from and after the Effective Time. Subject to the occurrence of Closing and subject to Section 2.4(b), Section 2.4(c), Section 2.4(d), Section 2.4(e) and Section 15.2(b), all Operating Expenses that are: (i) incurred with respect to operations conducted or production prior to the Effective Time shall be paid by or allocated to Seller; and (ii) incurred with respect to operations conducted or production from and after the Effective Time shall be paid by or allocated to Buyer. Such amounts that are received or paid prior to Closing shall be accounted for in the Preliminary Settlement Statement or Final Settlement Statement as applicable. After Closing, each Party shall be entitled to participate in all joint interest audits and other audits of Operating Expenses for which such Party is entirely or in part responsible under the terms of this Section 2.4; provided, that Buyer shall control any such joint audit on behalf of the Parties and shall not agree to any adjustments to previously assessed costs for which Seller is liable, or any compromise of any audit claims to which Seller would be entitled, without the prior written consent of Seller, which consent shall not be unreasonably withheld, conditioned or delayed. Any expenses from such audit shall be borne by Buyer and Seller in the same proportion as the Operating Expenses at issue are or would be borne by Buyer and Seller. Buyer shall provide Seller with a copy of all applicable audit reports and written audit agreements received by Buyer or its Affiliates and relating to periods for which Seller is wholly or partially responsible.

(b) Such amounts that are received or paid after Closing but prior to the date of the Final Settlement Statement shall be accounted for in the Final Settlement Statement. After the agreement of Buyer and Seller upon the Final Settlement Statement (or determination thereof), but prior to the two-year anniversary of the Closing Date (the “Cut-Off Date”), (i) if any Party receives monies that would belong to any other Party pursuant to this Section 2.4, including proceeds of production, then such amount shall, within 60 days after the end of the calendar month in which such amounts were received, be paid by such receiving Party to the proper Party, (ii) if any Party pays monies for Operating Expenses which are the obligation of any other Party pursuant to this Section 2.4, then such other Party shall, within 60 days after the end of the calendar month in which the applicable invoice and proof of payment of such invoice were received by such other Party, reimburse the Party which paid such Operating Expenses, (iii) if a Party receives an invoice of an Upstream Operating Expense which is owed by another Party pursuant to this Section 2.4, such Party receiving the invoice shall promptly forward such invoice to the Party obligated to pay the same, (iv) if Seller receives an invoice of a Midstream Operating Expense which is owed by Buyer or the Partnership pursuant to this Section 2.4, Seller shall promptly forward such invoice to Buyer and the Partnership, (v) if Buyer or the Partnership receives an invoice of a Midstream Operating Expense which is owed by Seller pursuant to this Section 2.4, Buyer or the Partnership shall pay the applicable invoice in accordance with its terms and following such payment forward a request for reimbursement of such paid amount to Seller, and Seller shall thereafter reimburse Buyer or the Partnership, as applicable, within 30 days of Seller’s receipt of the same, and (vi) if an invoice for Operating Expenses is received by a Party, which is partially an obligation of two or more Parties pursuant to this Section 2.4, then the relevant Parties shall consult with each other, and each shall promptly pay (or reimburse to Buyer or the Partnership, as applicable, in the event Seller owes any Midstream Operating Expense) its portion of such Operating Expenses.

(c) 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 and otherwise under this Agreement, 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, regardless of when the applicable invoice was sent. “Earned” and “incurred”, as used in this Agreement, shall be interpreted in accordance with GAAP and COPAS standards, as applied by Seller in the ordinary course of business consistent with past practice, subject to the other provisions of this Section 2.4. For purposes of allocating production (and accounts receivable with respect thereto), under this Section 2.4, (i) 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 (ii) gaseous Hydrocarbons shall be deemed to be “from or attributable to” the Wells when they pass through the production meters, flare meters, fuel use equipment, venting, or delivery point sales meters or similar meters at the entry point into the pipelines through which they are transported from such lands. Liquid Hydrocarbons in storage shall be measured by gauging of tanks at the Effective Time. Seller 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 data is not available.

(d) Notwithstanding anything to the contrary in this Section 2.4, (i) Seller shall be entitled to offset any amounts owed by Seller or its Affiliates to Buyer or its Affiliates under this Agreement or any of the Transaction Documents against any amounts owed by Buyer or its Affiliates to Seller or its Affiliates under this Agreement or any of the Transaction Documents and (ii) Buyer shall be entitled to offset any amounts owed by Buyer or its Affiliates to Seller or its Affiliates under this Agreement or any of the Transaction Documents against any amounts owed by Seller its Affiliates to Buyer or its Affiliates under this Agreement or any of the Transaction Documents.

(e) For the avoidance of doubt, the Parties agree that, notwithstanding anything in this Section 2.4, Section 8.2 or otherwise in this Agreement to the contrary, from and after the Cut-Off Date, Buyer shall be responsible for all Operating Expenses and, shall be entitled to all proceeds, in each case, related to the Upstream Assets and Midstream Interests, regardless of when such Operating Expenses were incurred or paid or when such proceeds of production were earned or received. Notwithstanding anything in this Section 2.4, Section 8.2 or otherwise in this Agreement to the contrary, from and after the Cut-Off Date, Seller shall (i) not be responsible for, or otherwise required to pay, any Operating Expenses, regardless when the same were incurred or paid, and (ii) not be entitled to any amounts received by Buyer or its Affiliates after the Cut-Off Date.

2.5 Midstream Interests Adjustment Procedures. For the avoidance of doubt, no item that is included in or taken into account in the calculation of Effective Time Working Capital shall be subject to any other adjustment to the Purchase Price.

(a) In making the adjustments contemplated under Section 3.3(a)(vii) or Section 3.3(b)(x), as applicable, the provisions of this Section 2.5 shall be taken into account; provided, the remainder of this Section 2.5, other than Section 2.5(d), shall in no way be construed as a limitation to the definition of any of Effective Time Working Capital, Working Capital Assets and Working Capital Liabilities.

(b) The following shall be deemed to constitute Working Capital Assets (without duplication):

(i) all (A) Cash and Cash Equivalents of the Partnership at the Effective Time, and (B) unpaid refunds payable to the Partnership on account of deposits, prepayments or similar items as set forth on Schedule 2.5(b)(i), and all insurance proceeds receivables of the Partnership attributable to periods prior to the Effective Time as set forth on Schedule 2.5(b)(i);

(ii) the amount of all pre-paid or deposited Midstream Operating Expenses and all other costs and expenses (other than Taxes) paid by or on behalf of the Partnership prior to the Effective Time that are attributable to the ownership of the Midstream Interests after the Effective Time, including bond and insurance premiums and deductibles paid or borne by or on behalf of the Partnership with respect to any period after the Effective Time (prorated as applicable);

(iii) all current Tax assets (other than Income Tax assets) of the Partnership related to prepaid deposits and refunds attributable to periods prior to the Effective Time; and

(iv) unpaid proceeds, receivables and amounts earned as of the Effective Time and any other unpaid amounts earned by the Partnership, in each case during any period before the Effective Time, excluding (i) all Pre-ET Intercompany Receivables and (ii) any receivables and other amounts that are more than 90 days past due except to the extent a corresponding allowance for doubtful accounts is included as a Working Capital Liability).

(i) the amount of all Midstream Operating Expenses that are unpaid as of the Effective Time that are attributable to the ownership of the Midstream Interests prior to the Effective Time, including bond and insurance premiums and deductibles paid or borne by or on behalf of Seller or its Affiliates with respect to any period after the Effective Time (prorated as applicable);

(ii) all current Tax liabilities (other than Income Tax liabilities) attributable to periods prior to the Effective Time;

(iii) all capital expenditures of the Partnership accrued but not paid as of the Effective Time;

(iv) Transaction Costs incurred but not yet paid by the Partnership at the Effective Time; and

(v) any Liabilities incurred or paid by the Partnership from and after the Effective Time until the Closing Date that (A) constitute Seller Obligations or Indebtedness or (B) were not so incurred or paid in the ordinary course of business, consistent with past practice, whether such Liabilities relate to pre- or post-Effective Time periods.

(d) The following shall be excluded from the calculation of Effective Time Working Capital (and shall not be included as a Working Capital Asset or Working Capital Liability):

(i) all Excluded Assets held by the Partnership, including all Partnership Excluded Assets;

(ii) all pre-Effective Time accounts receivable of the Partnership and any other obligations owed by any of Midstream Seller or its Affiliates to the Partnership, including all applicable accounts receivable evidencing Indebtedness, accounts, and obligations (collectively, “Pre-ET Intercompany Receivables”);

(iii) all Indebtedness, accounts, and Liabilities owed by the Partnership to any of Midstream Seller or its Affiliates (“Intercompany Payables”); and

(iv) all Third Party Debt and other Indebtedness of the Partnership.

(b) The Purchase Price shall be adjusted downward by the following amounts (without duplication):

(i) an amount equal to all proceeds actually received by Upstream Seller or its Affiliates attributable to the sale of Hydrocarbons produced from or allocable to the Upstream Assets during the period from and after the Effective Time, net of Burdens, transportation, and marketing and other post-production expenses (which expenses shall, for the avoidance of doubt, include all amounts payable by Upstream Seller pursuant to the QEP Gas Services Agreement for periods from and after the Effective Time

3.4 Preliminary Settlement Statement. Not less than five Business Days prior to the Scheduled Closing Date, Seller shall prepare and submit to Buyer for review a draft settlement statement (the “Preliminary Settlement Statement”) that shall set forth the Adjusted Purchase Price, reflecting each adjustment made in accordance with this Agreement as of the date of preparation of such Preliminary Settlement Statement and the itemized calculation and reasonable supporting documentation of the adjustments used to determine such amount, together with the designation of Seller’s account(s) for the wire transfers of funds as set forth in Section 6.3(f). When available, actual figures will be used for the determination of the Adjusted Purchase Price at Closing. To the extent actual figures are not available, good faith estimates will be used subject to final adjustments in accordance with Section 3.5 and Section 3.6. Within two Business Days of receipt of the Preliminary Settlement Statement, Buyer will deliver to Seller a written report containing all changes with the explanation therefor that Buyer proposes to be made to the Preliminary Settlement Statement. The Preliminary Settlement Statement, as agreed upon by the Parties, will be used to adjust the Purchase Price at Closing; provided that if the Parties do not agree upon an adjustment set forth in the Preliminary Settlement Statement, then the amount of such adjustment used to adjust the Purchase Price at Closing shall be that amount set forth in the draft Preliminary Settlement Statement delivered by Seller to Buyer pursuant to this Section 3.4.

3.5 Final Settlement Statement. On or before 180 days after the Closing, a final settlement statement (the “Final Settlement Statement”) will be prepared by Seller based on actual income and expenses during the period from and after the Effective Time until Closing and which takes into account all final adjustments made to the Purchase Price and shows the resulting final Adjusted Purchase Price. The Final Settlement Statement shall set forth the actual proration of the amounts required by this Agreement. As soon as practicable, and in any event within 30 days after receipt of the Final Settlement Statement, Buyer shall return to Seller a written report containing any proposed changes to the Final Settlement Statement and an explanation of any such changes and the reasons therefor (the “Dispute Notice”). Buyer’s failure to deliver to Seller a Dispute Notice detailing proposed changes to the Final Settlement Statement by such date shall be deemed to be an acceptance by Buyer of the Final Settlement Statement delivered by Seller and any changes to the Final Settlement Statement as initially prepared by Seller that are proposed or requested by Buyer and 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 prevail. If the final Purchase Price set forth in the Final Settlement Statement is mutually agreed upon by Seller and Buyer or deemed agreed pursuant to the foregoing (or determined by the Accounting Arbitrator pursuant to Section 3.6), the Final Settlement Statement and such final Adjusted Purchase Price (the “Final Price”), shall be final and binding on the Parties. Any difference in the Adjusted Purchase Price as paid at Closing pursuant to the Preliminary Settlement Statement and the Final Price shall be paid by the owing Party on or before the date that is ten Business Days following agreement or deemed agreement (or determination by the Accounting Arbitrator, as applicable) (such date, the “Final Payment Date”) to the owed Party. All amounts paid or transferred pursuant to this Section 3.5 shall be delivered in United States

currency by wire transfer of immediately available funds to the account specified in writing by the relevant Party.

3.6 Disputes. If Seller and Buyer are unable to resolve the matters addressed in the Dispute Notice, each of Buyer and Seller shall within 25 Business Days after the delivery of such Dispute Notice, summarize its position with regard to such dispute in a written document of 20 pages or less and submit such summaries to the Denver office of KPMG US LLP or such other Person as the Parties may mutually select (the “Accounting Arbitrator”), together with the Dispute Notice, the Final Settlement Statement, this Agreement and any other documentation such Party may desire to submit. Within 20 Business Days after receiving the Parties’ respective submissions, the Accounting Arbitrator shall determine such items of the calculation of the Adjusted Purchase Price after the dispute is submitted to it, based on the materials described above. To the extent that a value has been assigned by Buyer or Seller to any item subject to dispute that is submitted to the Accounting Arbitrator, the Accounting Arbitrator shall not assign a value to objection that is greater than the greatest value for such objection claimed by either Party or less than the smallest value for such objection claimed by either Party. Any decision rendered by the Accounting Arbitrator pursuant hereto shall be final, conclusive and binding on Seller and Buyer and will be enforceable against any of the Parties in any court of competent jurisdiction. Each Party shall bear its own costs with respect to any matters addressed in this Section 3.6. In the event that the Denver office of KPMG US LLP declines to serve as the Accounting Arbitrator, then each of Buyer and Seller may deliver to each other a list of up to three independent national accounting firms and the Accounting Arbitrator shall be selected by lot from among the independent national accounting firms submitted by the Parties. The costs of the Accounting Arbitrator shall be borne one-half by Buyer and one-half by Seller; provided, however, that the Accounting Arbitrator shall have the discretion to allocate all or a portion of its costs to the “losing” Party in connection with any such dispute. The Accounting Arbitrator shall be authorized to resolve only the specific disputed aspects of the Final Settlement Statement submitted by the Parties as provided above and, subject to the immediately preceding sentence, may not award damages, interest or penalties to any Party with respect to any matter.

3.7 Allocation of Purchase Price / Allocated Values. Buyer and Seller agree that (a) the unadjusted Purchase Price shall be allocated among the Upstream Assets and Midstream Interests as set forth in Schedule 3.7A, (b) the unadjusted Purchase Price attributable to the Upstream Assets as set forth on Schedule 3.7A shall be allocated among the Wells and the Well Locations as set forth in Schedule 3.7B and Schedule 3.7C, as applicable (for the Midstream Interests and each such Well and Well Location, its “Allocated Value”), (c) the Allocated Values shall be used in calculating adjustments to the Purchase Price as provided herein, (d) the Allocated Values, as adjusted, shall be used by Seller and Buyer as the basis for reporting asset values and other items for purposes of this Section 3.7, and (e) subject to Section 3.8, neither Party nor their Affiliates will take positions inconsistent with such Allocated Values in notices to Governmental Authorities, in audit or other proceedings with respect to Taxes, in connection with Preferential Purchase Rights or in other documents or notices relating to the transactions contemplated by this Agreement.

3.8 Allocation of Consideration for Tax Purposes. Seller and Buyer agree that the portion of the Purchase Price, as adjusted, and other amounts treated for Tax purposes as consideration (to the extent known at such time) (collectively, the “Allocable Amount”) shall be allocated among the Upstream Assets and the Midstream Assets for Tax purposes. The initial draft of such allocations shall be prepared by Buyer in a manner consistent with Section 1060 of the Code and the Treasury Regulations promulgated thereunder, and such initial draft shall be provided to Seller no later than 120 days after the Closing for Seller’s review and comment. Seller and Buyer shall then cooperate in good faith to prepare a final schedule of the Allocable Amount among the Assets (as adjusted, the “Allocation Schedule”). The Allocation Schedule shall be updated to reflect any adjustments to the Allocable Amount. The allocation of the Allocable Amount shall be reflected on a completed Internal Revenue Service Form 8594 (Asset Acquisition Statement under Section 1060),

which Form will be timely filed separately by Seller and Buyer with the Internal Revenue Service pursuant to the requirements of Section 1060(b) of the Code. Seller and Buyer agree not to take any position inconsistent with the allocations set forth in the Allocation Schedule unless required to do so by a determination as defined in Section 1313(a) of the Code (or any other similar provision of state or local law) or with the consent of the other Parties (such consent not to be unreasonably withheld, conditioned or delayed); provided, however, that neither Party shall be unreasonably impeded in its ability and discretion to concede, negotiate, compromise and/or settle any Tax audit, claim or similar proceeding in connection with the allocation set forth on the Allocation Schedule.

3.9 Allocation for Imbalances. Notwithstanding anything to the contrary in this Agreement, if, prior to Closing, any Party discovers an error in the Imbalances set forth in Schedule 9.12(a) and Schedule 9.12(b), then, notwithstanding anything to the contrary herein, as the applicable Party’s sole remedy in respect of such error, the Purchase Price shall be further adjusted at Closing pursuant to Section 3.3(a)(iii), Section 3.3(a)(iv), Section 3.3(a)(vii), Section 3.3(b)(vii), Section 3.3(b)(viii), or Section 3.3(b)(x), as applicable, and Schedule 9.12(a) and Schedule 9.12(b) will be deemed amended immediately prior to the Closing to reflect the Imbalances for which the Purchase Price is so adjusted. If, after the Closing, any Party discovers an error in the Imbalances set forth in Schedule 9.12(a) and Schedule 9.12(b) on or before the date of the delivery of the Final Settlement Statement pursuant to the provisions of Section 3.5, then the Party discovering such error shall notify the other Parties and, notwithstanding anything to the contrary herein, as the applicable Party’s sole remedy in respect of such error, the Parties shall settle such Imbalances based on the formula set forth in Section 2.5(b)(iv), Section 2.5(c)(ii), Section 3.3(a)(iii), Section 3.3(a)(iv), Section 3.3(a)(vii), Section 3.3(b)(vii), Section 3.3(b)(viii), or Section 3.3(b)(x), as applicable, as part of the process described in Section 3.5.

3.10 Withholding Taxes. Seller, Buyer and the Partnership shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement such amounts as are required to be deducted or withheld therefrom under applicable Law. Seller, Buyer, or the Partnership, as the case may be, shall provide written notice to Buyer or Seller, as applicable, at least five (5) days prior to any such withholding, which notice shall include an explanation and calculation of the proposed withholding, and the Parties shall use reasonable efforts to take any actions as may be necessary to reduce or otherwise minimize such withholding. To the extent that amounts are so deducted or withheld and paid over to the appropriate Governmental Authority, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding were made.

(f) by Buyer pursuant to Section 13.3(c); and

(g) by seller if the Deposit has not been delivered to the Escrow Agent within two Business Days after the Execution Date.

provided, however, that no Party shall have the right to terminate this Agreement pursuant to clause (b), (c), (d), (e) or (f) above if such Party or its Affiliates are at such time in material breach of any provision of this Agreement.

7.2 Effect of Termination. If this Agreement is terminated pursuant to any provision of Section 7.1, then, except as provided in this Section 7.2 and except for the provisions of Article I, Section 7.3, Section 8.11, Sections 12.1(d) through (f), Section 12.2, Section 12.3, Article XV (other than Section 15.2(b), Section 15.2(c)(i), Section 15.7, Section 15.8, Section 15.15 and Section 15.16) and Appendix A, this Agreement shall forthwith become void and of no further force or effect and the Parties shall have no liability or obligation hereunder. Each Party agrees that, to the fullest extent permitted by Law, such Party’s rights set forth in this Section 7.2 shall be its sole and exclusive remedies (other than with respect to those provisions that survive termination pursuant to the preceding sentence) if the Closing does not occur as a result of the termination of this Agreement pursuant to Section 7.1.

(a) If Seller has the right to terminate this Agreement pursuant to Section 7.1(c) because of (i) the Willful Breach by Buyer of this Agreement, or (ii) the failure of Buyer to close the transactions contemplated by this Agreement in the instance where, as of the Outside Date, (A) all of the conditions in Article IV (excluding conditions that, by their terms, cannot be satisfied until the Closing) have been satisfied (or waived by Buyer), (B) Seller is ready, willing and able to perform its obligations under Section 6.3, and (C) Buyer nevertheless elects not to close the transactions contemplated by this Agreement, then, in either such event Seller shall be entitled to terminate this Agreement pursuant to Section 7.1(c) and be entitled to receive the Deposit and the Escrow Earnings as liquidated damages as Seller’s sole and exclusive remedy, and not as a penalty, for such termination, free and clear of any claims thereon by Buyer. The Parties agree that the foregoing described liquidated damages are reasonable considering all of the circumstances existing as of the Execution Date and constitute the Parties’ good faith estimate of the actual damages reasonably expected to result from such termination of this Agreement by Seller. If Seller is entitled to receive the Deposit and the Escrow Earnings pursuant to this Section 7.2(a), within five Business Days of the date this Agreement is terminated, Seller and Buyer shall execute and deliver a joint instruction to the Escrow Agent to deliver all of the funds in the Escrow Account to Seller.

(b) If Buyer has the right to terminate this Agreement pursuant to Section 7.1(b) because of (i) the Willful Breach by Seller of this Agreement, or (ii) the failure of Seller to close the transactions contemplated by this Agreement in the instance where, as of the Outside Date, (A) all of the conditions in Article V (excluding conditions that, by their terms, cannot be satisfied until the Closing) have been satisfied

(or waived by Seller), (B) Buyer is ready, willing and able to perform its obligations under Section 6.3, and (C) Seller nevertheless elects not to close the transactions contemplated by this Agreement, then, in either such event, Buyer shall be entitled to (1) terminate this Agreement pursuant to Section 7.1(b) and be entitled to receive the Deposit and the Escrow Earnings, free and clear of any claims thereon by Seller, and seek to recover actual, direct damages (subject to Section 8.11) from Seller up to but not exceeding the aggregate amount of the Deposit and the Escrow Earnings or (2) seek to obtain the specific performance of Seller hereunder. If Buyer is entitled to receive the Deposit and the Escrow Earnings pursuant to this Section 7.2(b), within five Business Days of the date this Agreement is terminated, Seller and Buyer shall execute and deliver a joint instruction to the Escrow Agent to deliver all of the funds in the Escrow Account to Buyer. Nothing herein shall be construed to prohibit Buyer from first seeking specific performance, but thereafter terminating this Agreement and receiving the Deposit and the Escrow Earnings and seeking to recover actual, direct damages (as limited by Section 8.11) from Seller up to but not exceeding the amount of the Deposit. Each Party acknowledges and agrees that the remedies at Law of Buyer for a breach or threatened breach of this Agreement by Seller as contemplated pursuant to Section 7.2(b)(i) or Section 7.2(b)(ii) are likely inadequate and, in recognition of this fact, Buyer, without posting any bond or the necessity or proving the inadequacy as a remedy of monetary damages, and in addition to all other remedies that may be available, shall be entitled to seek to obtain equitable relief in the form of specific performance, a temporary restraining order, a temporary or permanent injunction and/or any other equitable remedy that may then be available.

(c) If this Agreement is terminated for any reason other than as set forth in Section 7.2(a) or Section 7.2(b), then the Parties shall have no liability or obligation hereunder as a result of such termination, and Buyer and Seller shall, within five Business Days of the date this Agreement is terminated, provide joint written instructions to the Escrow Agent to release all of the funds in the Escrow Account to Buyer free and clear of any claims thereon by Seller.

(d) Subject to the foregoing, upon the termination of this Agreement neither Party shall have any other liability or obligation hereunder.

(e) Seller’s retention of the Deposit and the Escrow Earnings pursuant to Section 7.2(a) shall be the sole and exclusive remedy of Seller against Buyer, the Financing Sources and their respective Affiliates for any and all losses, claims, expenses, liabilities or damages suffered or incurred by Seller or any other Person in connection with this Agreement, the Financings (and the termination thereof), the transactions contemplated hereby and thereby (and the abandonment or termination thereof) or any matter forming the basis of such termination and none of the Financing Sources shall have any further liability or obligation relating to or arising out of this Agreement or the Financings or the transactions contemplated hereby or thereby (or the abandonment or termination thereof) or any matters forming the basis for such termination upon payment of such amount.

7.3 Return of Documentation and Confidentiality. Upon termination of this Agreement, Buyer shall return to Seller all title, engineering, geological and geophysical data, environmental assessments and/or reports, maps, documents and other information furnished by Seller to Buyer or prepared by or on behalf of Buyer in connection with its due diligence investigation of the Assets and an officer of Buyer shall certify same to Seller in writing.

(c) In the case of a claim for indemnification based upon a Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim Notice to notify the Indemnified Party whether it admits or denies its liability to defend the Indemnified Party against such Claim at the sole cost and expense of the Indemnifying Party.

Buyer and its Affiliates may

conduct interviews and screening of the Permitted Employees from the Execution Date until 20 days before the Scheduled Closing Date (such date, which may be extended in the sole discretion of Seller, the “Offer Period End Date”); provided that such interviewing and screening shall not unreasonably interfere with the business of Seller or its Affiliates.

Each Continuing Employee shall, as of the Closing Date or, in the case of a TSA Employee, as of their applicable TSA Services Termination Date (if he or she is still employed by Seller or its Affiliate), be terminated by Seller or its Affiliate (and Seller shall and shall cause its Affiliates to release such Continuing Employee from all non-compete or similar restrictions that would restrict or be violated in any way by, such Continuing Employee’s activities as an employee of Buyer or its Affiliate) and become an employee of Buyer or its Affiliate.

Nothing herein shall require Buyer to continue to employ any Continuing Employee for any specified period of time; provided, however, that, if Seller timely provides to Buyer a list of applicable employees terminated by Seller in connection with or within 90 days prior to the Closing and, as a direct result of Buyer’s action to terminate or lay off any Continuing Employee on or after

the Closing other than for cause, Seller or any of its Affiliates incur any Liability under the WARN Act, Buyer shall promptly reimburse Seller or its Affiliate, as applicable, for any such Liability.

(e) Buyer hereby agrees not to, and to cause its Affiliates or anyone acting on its or any of its Affiliates’ behalf not to, for a period of two years after the Execution Date, directly or indirectly (other than as permitted by Section 11.10(a) and Section 11.10(b) with respect to Permitted Employees): solicit or contact with a view to the engagement or employment of, any employee of Seller or its Affiliates; provided, however, that it shall not be a violation of this Section 11.10(e) to engage in solicitations incidental to general advertising or other general solicitation in the ordinary course not specifically targeted at any employee or group of employees of Seller and its Affiliates or to employ any Person not solicited in violation hereof; and provided, further, however, that, except pursuant to an Offer extended to a Permitted Employee prior to the Closing in accordance with Section 11.10(a) and Section 11.10(b), for a period of six months following the Closing Date, if Buyer or any of its Affiliates hires or otherwise employs any Permitted Employee that was terminated or laid off by Seller or its Affiliates and to which Seller or an Affiliate of Seller made or provided a severance payment or severance benefits to such employee upon being terminated or laid off, Buyer shall promptly reimburse Seller or its applicable Affiliate an amount equal to 50% of the severance payment and cost of severance benefits made or provided to such Permitted Employee (together with 50% of the employer portion of any employment, payroll or similar Taxes paid by Seller or its Affiliates in connection therewith).

If Seller or its applicable Affiliate has executed and delivered any EHC Novation Instrument in accordance with this Section 11.20(a) and the proposed counterparty thereto or Buyer fails to execute and deliver such EHC Novation Instrument, Seller shall not be in breach of this Section 11.20(a) for such counterparty’s or Buyer’s failure to execute and deliver such EHC Novation Instrument.

(b) At Closing, the Purchase Price shall be increased or decreased, as applicable, by the amount the Existing Hedge Contracts, on an aggregate net basis, have a positive value or a negative value, respectively, to Seller or its applicable Affiliate, in each case as of the Execution Date (such amount, the “EHC Aggregate Value”). The EHC Aggregate Value attributable to each Existing Hedge Contract shall be determined based on the mid-market value with respect to such Existing Hedge Contract provided by the applicable counterparty to such Existing Hedge Contract on the Execution Date, and Seller agrees to request such value attributable to such Existing Hedge Contract from each such counterparty prior to, but as of, the Execution Date; provided that if a counterparty does not provide any such amount, or if Seller or Buyer both believe that any such amount with respect to an Existing Hedge Contract so provided does not represent a commercially reasonable estimate of the value of such Existing Hedge Contract as of the Execution Date, then Buyer and Seller shall, prior to the delivery of the Final Settlement Statement, cooperate to obtain three mid-market quotations of the value of such Existing Hedge Contract as of the Closing Date from leading dealers in the relevant hedge product, and the EHC Aggregate Value with respect to such Existing Hedge Contract shall be determined based upon the average of the bids received. If no such bids are received, Buyer and Seller shall cooperate in good faith to determine the value of the applicable Existing Hedge Contract as of the Execution Date prior to the delivery of the Final Settlement Statement.

ARTICLE XII

ACCESS; DISCLAIMERS

12.1 Access.

(a) From and after the Execution Date and up to and including the Defect Claims Date (or earlier termination of this Agreement), but subject to the other provisions of this Section 12.1 and obtaining any required consents of Third Parties, including Third Party operators of the Assets (which consents Seller shall use commercially reasonable efforts to obtain but shall not be required to incur any Liabilities with respect thereto), Seller shall, and shall cause the Partnership to, afford to Buyer and its Representatives (“Buyer’s Representatives”) reasonable access, during normal business hours, to (i) the Upstream Assets and Midstream Assets and (ii) all Records in Seller’s or any of its Affiliates’ (including the Partnership’s)

possession. All investigations, due diligence and Survey activities conducted by Buyer or any Buyer’s Representative shall be conducted at Buyer’s sole cost, risk and expense and any conclusions made from any examination done by Buyer or any Buyer’s Representative shall result from Buyer’s own independent review and judgment.

(b) Buyer shall be entitled to conduct a Phase I Environmental Site Assessment with respect to the Assets, subject to the other provisions of this Section 12.1 and obtaining any required consents of Third Parties, including Third Party operators of the Assets (which consents Seller shall use commercially reasonable efforts to obtain but shall not be required to incur any Liabilities with respect thereto), but such inspection rights shall be limited to conducting a Phase I Environmental Site Assessment of the Upstream Assets and Midstream Assets and Buyer and the Buyer’s Representatives shall not conduct any Phase II Environmental Site Assessment or operate any equipment or conduct any testing, boring, sampling, drilling or other invasive investigation activities (in each case) on or with respect to any of the Assets without the prior written consent of Seller, which consent may be withheld in Seller’s sole discretion. Seller may approve Buyer’s request to conduct said Phase II Environmental Site Assessment activities, in whole or in part, and Buyer shall not have the right to conduct any activities set forth in such request until such time that Seller has approved such activities in writing. Seller or its designee shall have the right to accompany Buyer and Buyer’s Representatives whenever they are on site on the Assets (including in connection with any Survey related activities) and also to collect split test samples if any are permitted to be collected. Notwithstanding anything herein to the contrary (including the provisions of this Section 12.1(b)), Buyer shall not have access to, and shall not be permitted to conduct, any environmental due diligence (including any Phase I Environmental Site Assessment or Phase II Environmental Site Assessment) with respect to any Assets where Seller does not have the authority to grant access for such due diligence (provided, however, Seller shall use its commercially reasonable efforts to obtain permission from any Third Party to allow Buyer and Buyer’s Representatives such access but shall not be required to incur any Liabilities with respect thereto). If (i) any Phase I Environmental Site Assessment reflects a reasonable basis for Buyer to conduct Phase II Environmental Site Assessment activities and (ii) Seller rejects or otherwise declines or fails to approve Buyer’s request to conduct Phase II Environmental Site Assessment activities proposed by Buyer with respect to any Upstream Asset where Seller has authority to grant access for such due diligence, then Buyer shall have the right, exercisable by written notice to Seller on or before the Defect Claims Date, to exclude from the transactions contemplated by this Agreement such Upstream Asset, and any such excluded Upstream Asset shall be deemed Excluded Assets hereunder and the Purchase Price shall be adjusted downward by the aggregate of the Allocated Value thereof pursuant to Section 3.3(b)(iv).

(c) Buyer shall coordinate its environmental property assessments, physical inspections of the Assets and Survey related activities with Seller and all Third Party operators to minimize any inconvenience to or interruption of the conduct of business by Seller or such Third Party operators. Buyer shall abide by Seller’s, and any Third Party operator’s, safety rules, regulations and operating policies while conducting its due diligence evaluation of, and Survey activities relating to, the Assets, including any environmental or other inspection or assessment of the Assets, and to the extent required by any Third Party operator, execute and deliver any required bonding or access agreement of such Third Party operator or provide evidence that Buyer maintains insurance as may be required by such Third Party operator. Buyer hereby releases, defends, indemnifies and holds harmless each of the operators of the Assets and the Seller Indemnified Parties from and against any and all Liabilities (i) for any personal injury, death, loss or damage arising out of such entry that may occur to Buyer or any Buyer’s Representatives arising out of, resulting from or relating to any field visit, environmental property assessment, Survey activity, or other due diligence activity conducted by Buyer or any Buyer’s Representative with respect to the Assets or (ii) reasonably arising out of or resulting from any field visit, environmental property assessment, Survey activity, or other due diligence activity conducted by Buyer or any Buyer’s Representative with respect to the Assets, even if such

Liabilities arise out of or result from, SOLELY OR IN PART, the sole, active, passive, concurrent or comparative negligence, strict liability or other fault or violation of Law of or by a member of THE Seller Indemnified Parties, excepting only IN THE CASE OF THIS SECTION 12.1(c) Liabilities actually resulting on the account of the gross negligence or willful misconduct of a member of THE Seller Indemnified Parties; provided, however, that Buyer shall have no indemnification obligations to the Seller Indemnified Parties pursuant to this Section 12.1(c) for any losses that arise from the identification of any preexisting Environmental Conditions or noncompliance with Environmental Laws that are discovered by Buyer or any Buyer’s Representative during such due diligence investigation.

(d) Buyer agrees to promptly provide Seller, no later than the Defect Claims Date, copies of all (i) Surveys prepared by Buyer and/or any of Buyer’s Representatives if related to any Environmental Defect Property, and (ii) final environmental reports and environmental test results prepared by Buyer and/or any of Buyer’s Representatives which contain environmental data collected or generated from Buyer’s environmental due diligence with respect to the Assets and/or Midstream Business (including any drafts thereof). None of Buyer, any of Buyer’s Representatives or Seller shall be deemed by Seller’s receipt of said documents, or otherwise, to have made any representation or warranty, expressed, implied or statutory, as to the condition of the Assets or the Midstream Business or to the accuracy of said documents or the information contained therein.

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

(f) During all periods a Buyer and/or any Buyer’s Representatives are on the Assets or any lands underlying such Assets, Buyer shall maintain, at its sole expense, policies of insurance of types and in amounts sufficient to cover the obligations and Liabilities of such Buyer under Section 12.1(c) and Section 12.1(e). Upon request by Seller, Buyer shall provide evidence of such insurance to Seller prior to entering the Assets or any lands underlying the Assets.

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

ARTICLE XIII

TITLE MATTERS; CASUALTY; TRANSFER RESTRICTIONS

13.1 Seller’s Title.

(a) General Disclaimer of Title Warranties and Representations. Without limiting (i) Buyer’s remedies for Title Defects set forth in this Article XIII, (ii) Buyer’s rights under the Special Warranty, (iii) Buyer’s remedies for breaches of the representations and warranties of Seller set forth in Section 9.20 and (iv) Buyer’s remedies for breaches of the covenants of Seller set forth in Section 11.1(b)(ii), Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to title to any of the Assets and, Buyer acknowledges and agrees that Buyer has not relied upon any such representation or warranty and that Buyer’s sole and exclusive remedy for (A) any defect of title, including any Title Defect, with respect to any of the Upstream Assets (1) before Closing, shall be as set forth in Section 13.2 and (2) after Closing, shall be pursuant to the Special Warranty, subject to the provisions of Section 13.1(c), and Section 8.2(b) (as related to the covenants of Seller set forth in Section 11.1(b)(ii)) and Section 8.2(d) (as related to the Retained Litigation) and (B) any failure by Seller to obtain any Consents or waivers of Preferential Purchase Rights as contemplated by Section 13.4 shall be as set forth in Section 13.4.

(b) Special Warranty of Title. The Upstream Assignment and the Deed delivered at Closing will contain a special warranty of Defensible Title to the Wells and Well Locations by Upstream Seller, subject, however, to the provisions of Section 13.1(c) (the “Special Warranty”).

(c) Recovery on Special Warranties. Buyer shall furnish Upstream Seller a notice meeting the requirements of Section 13.2(a) setting forth any matters which Buyer intends to assert as a breach of the Special Warranty contained in the Upstream Assignment. Upstream Seller shall have a reasonable opportunity, but not the obligation, to cure any breach of the Special Warranty asserted by Buyer. Buyer agrees to reasonably cooperate with any attempt by Upstream Seller to cure same. For purposes of the Special Warranty contained in the Upstream Assignment, the value of the Wells and Well Locations set forth in Schedule 3.7B and Schedule 3.7C, as applicable, shall be deemed to be the Allocated Value thereof, as adjusted pursuant to this Agreement. Recovery on the Special Warranty shall be limited to an amount (without any interest accruing thereon) equal to the reduction in the Purchase Price to which Buyer would have been entitled had Buyer asserted the defect giving rise to such breach of the Special Warranty as a Title Defect prior to the Defect Claims Date pursuant to Section 13.2, excluding and without regard to the application of the Individual Title Defect Threshold or the Defect Deductible and Buyer hereby expressly waives any and all other recovery under the Special Warranty with respect thereto. Buyer is not entitled to protection under Upstream Seller’s Special Warranty, as described above and contained in the Assignment, against (i) any matter reported by Buyer under Section 13.2(a), (ii) any matter reported to Upstream Seller after the three-year anniversary of the Closing Date, and/or (iii) any matter that would not otherwise be a Title Defect under this Agreement. Seller shall be entitled to offset any amount owed by Seller for breach of the Special Warranty with respect to any Upstream Asset by the amount (without duplication of any amounts previously applied as an offset against any Title Defect Amount or any claim under the Special Warranty) of any Title Benefits with respect to such Upstream Asset as to which Seller give Buyer notice after the Defect Claims Date; provided that, Buyer shall be entitled to object to any such Title Benefit and/or the Title Benefit Amount of any such Title Benefit and if the Parties cannot agree on the validity or amount of any such Title Benefit, such matters shall be resolved in accordance with Section 13.2(j), mutatis mutandis.

13.2 Notice of Title Defects; Defect Adjustments.

(a) Title Defect Notices. Buyer must deliver to Upstream Seller, on or before 5:00 p.m. (Central Time) on December 31, 2018 (the “Defect Claims Date”), claim notices meeting the requirements of this Section 13.2(a) (collectively the “Title Defect Notices” and individually a “Title Defect Notice”) setting forth any matters which, in Buyer’s reasonable opinion, constitute Title Defects and which Buyer intends to assert as a Title Defect pursuant to this Section 13.2. For all purposes of this Agreement and notwithstanding anything herein to the contrary, but without limiting (x) Buyer’s rights under the Special Warranty (subject to Section 13.1(c)) and (y) Buyer’s remedies for breaches of the covenants of Seller set forth in Section 11.1(b)(ii), Buyer shall be deemed to have waived, and Seller shall have no liability for, any Title Defect that Buyer fails to assert as a Title Defect by a Title Defect Notice meeting the requirements of this Section 13.2(a) that is received by Upstream Seller on or before the Defect Claims Date. To be effective, each Title Defect Notice shall be in writing and shall include (i) a reasonably identifiable description of the alleged Title Defect and the Well or Well Location (including a reasonable description of such Well or Well Location, the Leases(s) contributing to such Well or Well Location, and the affected Subject Formation(s) with respect to such Well or Well Location), or portions thereof, affected by such Title Defect (each a “Title Defect Property”), (ii) the Allocated Value of each Title Defect Property, (iii) the amount by which Buyer reasonably believes the Allocated Value of each Title Defect Property is reduced by such Title Defect and Buyer’s computations with respect thereto and (iv) supporting documents reasonably available to Buyer and reasonably necessary for Upstream Seller to verify the existence of such Title Defect and Buyer’s computations with respect thereto. To give Upstream Seller an opportunity to commence reviewing and curing Title Defects, Buyer agrees to use reasonable efforts to give Upstream Seller, on or before the end of each calendar week prior to the Defect Claims Date, written notice of all Title Defects discovered by Buyer during the preceding calendar week, which notice may be preliminary in nature and supplemented prior to

the Defect Claims Date; provided that, the failure to provide any such notices of a Title Defect shall not prejudice Buyer’s right to assert such Title Defect hereunder on or before the Defect Claims Date.

(b) Title Benefit Notices. Upstream Seller shall have the right, but not the obligation, to deliver to Buyer on or before the Defect Claims Date with respect to each Title Benefit a notice (a “Title Benefit Notice”) including (i) a description of the Title Benefit and the Wells (including the legal description of such Well or Well Location, the Leases(s) contributing to such Well or Well Location, and the affected Subject Formation(s) with respect to such Well or Well Location), or portions thereof, affected by such Title Benefit (each a “Title Benefit Property”), (ii) the amount by which Upstream Seller reasonably believes the Allocated Value of such Assets is increased by the Title Benefit and Upstream Seller’s computations with respect thereto and (iii) supporting documents reasonably necessary for Buyer to verify the existence of such Title Benefit and Seller’s computations with respect thereto. Notwithstanding anything in this Agreement, Seller may not assert any Title Benefit with respect to any Well or Well Location that is subject to any Scheduled Concursus Matter.

(c) Upstream Seller’s Right to Cure. Upstream Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure, at any time prior to 120 days after Closing (the “Cure Period”), any Title Defects of which Upstream Seller has been advised by Buyer. During the period of time from Closing to the expiration of the Cure Period, Buyer agrees to afford Upstream Seller and its officers, employees and other authorized Representatives reasonable access, during normal business hours, to the Upstream Assets and all Upstream Records in Buyer’s or any of its Affiliates’ possession or control, together with a right to copy such Upstream Records at Upstream Seller’s sole cost, in order to facilitate Upstream Seller’s attempt to cure any such Title Defects. The Purchase Price will be reduced at Closing as provided in Section 13.2(j) with respect to any Title Defect for which Upstream Seller has provided notice to Buyer prior to or on the Closing Date that Upstream Seller intends to attempt to cure during the Cure Period and that is not cured to Buyer’s satisfaction as of Closing and, subject to Section 13.2(d), the applicable Title Defect Property shall be conveyed to Buyer at Closing. An election by Upstream Seller to attempt to cure a Title Defect shall be without prejudice to its rights under Section 13.2(j) and shall not constitute an admission against interest or a waiver of Upstream Seller’s right to dispute the existence, nature or value of, or cost to cure, the alleged Title Defect.

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

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

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

(iii) exclude the entirety of the Title Defect Property that is subject to such Title Defect, together with all associated Upstream Assets to the extent required to produce Hydrocarbons from such Title Defect Property, from the Upstream Assets in which event the Purchase Price shall be reduced by

an amount equal to the Allocated Value of such Title Defect Property and associated Upstream Assets and such Title Defect Property and the associated Upstream Assets shall be treated as Excluded Assets under this Agreement.

In the event that the Parties do not agree in writing by the Closing on an election of alternative (i), (ii) or (iii) above with respect to any Title Defect, the Parties shall be deemed to have elected alternative (i) with respect to such Title Defect, subject to Section 13.2(j); provided that if the Title Defect Amount associated with any Title Defect Property as asserted by Buyer (after giving effect to any reduction thereof as agreed to by Buyer or determined by the Title Arbitrator, if applicable, due to efforts by Seller prior to Closing to cure such Title Defect) equals or exceeds 100% of the Allocated Value of such Title Defect Property, then Upstream Seller may elect alternative (iii) with respect to such Title Defect Property.

(e) Remedies for Title Benefits. With respect to each Title Benefit Property reported under Section 13.2(b), the aggregate Title Defect Amounts attributable to all Title Defects properly raised pursuant to Section 13.2(a) and uncured shall be decreased by an amount (the “Title Benefit Amount”) equal to the increase in the Allocated Value for such Title Benefit Property caused by such Title Benefit, as determined pursuant to Section 13.2(h) or Section 13.2(j), and Seller shall not be entitled to any remedy with respect to any Title Benefit Amounts in excess of the aggregate Title Defect Amounts raised hereunder.

(f) Exclusive Remedy. Except for Buyer’s (i) rights under the Special Warranty, subject to the provisions of Section 13.1(c), (ii) rights to terminate this Agreement pursuant to Section 7.1(d), (iii) rights under Section 8.2(a) (as related to the representations and warranties of Seller set forth in Section 9.20) and (iv) rights under Section 8.2(b) (as related to the covenants of Seller set forth in Section 11.1(b)(ii)) and Section 8.2(d) (as related to the Retained Litigation), the provisions set forth in Section 13.2(d) shall be the sole and exclusive right and remedy of Buyer with respect to Upstream Seller’s failure to have Defensible Title or any other title matter with respect to any Upstream Asset.

(g) Title Defect Amount. The amount by which the Allocated Value of the affected Title Defect Property is reduced as a result of the existence of a Title Defect shall be the “Title Defect Amount” and shall be determined in accordance with the following terms and conditions:

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

(ii) if the Title Defect is an Encumbrance that is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Defect Property; provided that if such Encumbrance affects more than one Title Defect Property, the Title Defect Amount shall be the aggregate amount necessary to be paid to remove the Title Defect from all such Title Defect Properties (and not counted in duplicate as to each Title Defect Property);

(iii) if (I) the Title Defect represents a negative discrepancy between (A) Upstream Seller’s Net Revenue Interest for the Subject Formation of any Well or Well Location and (B) Upstream Seller’s Net Revenue Interest for the Subject Formation of such Well or Well Location as set forth in Exhibit B-1 or Exhibit B-2, as applicable, and (II) Upstream Seller’s Working Interest in such Well or Well Location is proportionately decreased from the amount as set forth on Exhibit B-1 or Exhibit B-2, as applicable, then the Title Defect Amount shall be the product of (1) the Allocated Value of such Title Defect Property, multiplied by (2) a fraction, the (x) numerator of which is the Net Revenue Interest decrease for the applicable Subject Formation of such Well or Well Location, and (y) denominator of which is the Net Revenue Interest for the applicable Subject Formation of such Well or Well Location as set forth in Exhibit B-1 or Exhibit B-2;

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

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

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

(vii) notwithstanding anything to the contrary in this Article XIII, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any single Title Defect Property (whether related to an adjustment to the Purchase Price or any other remedy provided by Seller hereunder or any claim for any breach of the Special Warranty) shall not exceed the lesser of: (A) the actual cost and expense of curing such Title Defect (if such Title Defect is actually capable of being cured) and (B) the Allocated Value of such Title Defect Property; provided that this Section 13.2(i)(vii) shall not apply to limit the Title Defect Amount with respect to any Title Defect as described in Section 13.2(g)(ii).

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

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

(ii) if (I) the Title Benefit represents a positive discrepancy between (A) Upstream Seller’s Net Revenue Interest for the Subject Formation of any Well or Well Location, and (B) Upstream Seller’s Net Revenue Interest for the Subject Formation of such Well or Well Location as set forth in Exhibit B-1 or Exhibit B-2, as applicable, and (II) Upstream Seller’s Working Interest in such Well or Well Location is proportionately increased from the amount as set forth on Exhibit B-1 or Exhibit B-2, as applicable, then the Title Benefit Amount shall be the product of (1) the Allocated Value of the affected Well or Well Location, as applicable, multiplied by (2) a fraction, the (x) numerator of which is the Net Revenue Interest increase for the applicable Subject Formation of such Well or Well Location, as applicable, and (y) denominator of which is the Net Revenue Interest for the applicable Subject Formation of such Well or Well Location as set forth in Exhibit B-1 or Exhibit B-2, as applicable; 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 Upstream Asset affected by such Title Benefit, the portion of such Upstream Asset affected by such Title Benefit, the legal effect of the Title Benefit, the potential economic effect of the Title Benefit over the life of such Asset, the values placed upon the Title Benefit by Buyer and Upstream Seller and such other reasonable factors as are necessary to make a proper evaluation.

(i) Threshold and Deductible. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any individual Title Defect for which the Title Defect Amount does not exceed $75,000 (“Individual Title Defect Threshold”), provided that if a Title Defect (or the facts or circumstances resulting in or giving rise to a Title Defect) is applicable to or affects multiple Title Defect Properties, the Title Defect Amount for each affected Title Defect Property shall be aggregated for purposes of determining if the Individual Title Defect Threshold is met; and (ii) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any Title Defect that exceeds the Individual Title Defect Threshold unless (A) the sum of (1) the Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold (excluding any Title Defects cured by Seller or retained by Seller pursuant to Section 13.2(d)(iii)), plus (2) all Remediation Amounts of all Environmental Defects that exceed the Individual Environmental Defect Threshold (excluding any Environmental Defects Remediated by Seller or retained by Seller pursuant to Section 14.1(c)(iii)), minus (3) all Title Benefit Amounts, exceeds (B) the Defect Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price or other remedies only with respect to Title Defects relating to Title Defect Amounts in excess of such Defect Deductible. For avoidance of doubt, the Individual Title Defect Threshold is a threshold and shall not be applied as a deductible if the Individual Title Defect Threshold is exceeded by the applicable Title Defect Amount. For the avoidance of doubt, if Seller indemnifies Buyer with respect to any Title Defect Property pursuant to a Title Indemnity Agreement or retains any Title Defect Property pursuant to Section 13.2(d)(iii), then, in each case the Title Defect Amount related to such Title Defect Property will not be counted towards the Defect Deductible. This Section 13.2(i) shall be applied in this Agreement without giving duplicative effect to its application under this Section 13.2 and Section 14.1.

(j) Title Dispute Resolution/Escrow.

(i) Upstream Seller and Buyer shall undertake commercially reasonable efforts to agree on (A) all Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts prior to Closing and (B) whether or not any Title Defect that Upstream Seller elects to cure pursuant to Section 13.2(c) has been cured (or if not so cured the Title Defect and/or Title Defect Amount applicable thereto) by the expiration of the Cure Period (each such matter to which the Parties do not agree, a “Title Dispute”). If Upstream Seller and Buyer are so unable to agree by the Closing Date on any Title Dispute (including any efforts by Seller prior to the Closing to cure any Title Defect), or if any Title Defect that Upstream Seller elects to cure pursuant to Section 13.2(c) has been not cured to Buyer’s satisfaction as of the Closing Date, then, in either such case, (1) such Title Dispute shall be exclusively and finally resolved pursuant to this Section 13.2(j), subject to the proviso of Section 4.4 and Seller’s continuing right to cure the Title Defect giving rise to such Title Dispute until the expiration of the Cure Period, (2) an amount equal to the sum of (x) if the Parties had elected (or were deemed to have elected) the remedies set forth in Section 13.2(d)(i) or Section 13.2(d)(ii) with respect to the applicable Title Defect, the Title Defect Amount claimed by Buyer in good faith in the applicable Title Defect Notice applicable to such Title Defect, and (y) if the Parties (or Upstream Seller, as permitted under Section 13.2(d)) had elected the remedy set forth in Section 13.2(d)(iii) with respect to the applicable Title Defect, the Allocated Value of the Upstream Assets subject to such Title Dispute, as limited by Section 13.2(i) (such amount, as determined in the aggregate with respect to all applicable Title Disputes, the “Closing Date Title Escrow Amount”) will be deposited by Buyer with the Escrow Agent to be held pursuant to the Escrow Agreement and Section 13.2(j)(iv) and (3) the Purchase Price will be reduced at the Closing by the Closing Date Title Escrow Amount. For the avoidance of doubt, unless the Parties elect (or Upstream Seller, as permitted under Section 13.2(d)) elects) the remedy set forth in Section 13.2(d)(iii) with respect to any Title Dispute, in which case such Upstream Assets shall be retained by Upstream Seller at Closing, the Upstream Assets subject to any such Title Dispute shall be conveyed to Buyer at Closing pursuant to the Assignment.

(ii) There shall be a single arbitrator, who shall be a title attorney with at least ten years’ experience in oil and gas titles involving properties in the regional area in which the Title Defect Properties are located, as selected by mutual agreement of Buyer and Upstream Seller within 15 days after the end of the Cure Period (the “Title Arbitrator”). In the event the Parties are unable to mutually agree upon the Title Arbitrator within such time period, then either Party may petition the AAA to select a neutral party who has never been an officer, director or employee of or performed material work for the Parties or any of their Affiliates within the preceding five year period as Title Arbitrator, with due regard given to the selection criteria above and input from the Parties. In the event the AAA should fail to select the Title Arbitrator within 90 days from initiation of arbitration, then either party to the Title Dispute may petition any United States District Judge for the District of Colorado to select the Title Arbitrator. The arbitration proceeding shall be held in Denver, Colorado.

(iii) Within ten Business Days after the selection of the applicable Title Arbitrator, the Parties shall provide to such Title Arbitrator the documents and materials described in this Section 13.2(j)(iii), as applicable: (A) each Title Defect Notice and all documentation provided therewith with respect to each disputed Title Defect; (B) each Title Benefit Notice and all documentation provided therewith with respect to each disputed Title Benefit; (C) such evidence as Upstream Seller deems appropriate to explain and dispute the existence, waiver and cure of each disputed Title Defect or the Title Defect Amount assigned thereto by Buyer in any Title Defect Notice, together with Upstream Seller’s good faith estimate of the Title Defect Amount, if any, with respect to each such disputed Title Defect; and (D) such evidence as Buyer deems appropriate to dispute the existence of any disputed Title Benefit or the Title Benefit Amount assigned thereto in any Title Benefit Notice with respect any such disputed Title Benefit, together with Buyer’s good faith estimate of the disputed Title Benefit Amount, if any, with respect to each such disputed Title Benefit. Each of Buyer and Seller also shall furnish to the Title Arbitrator such workpapers and other documents and information relating to each Title Dispute as the Title Arbitrator may request and are available to that Party or its Affiliates, and each of Buyer and Seller will be afforded the opportunity to present to the Title Arbitrator any material relating to each Title Dispute as such Party shall deem appropriate to support its position with respect to each such matter and to discuss such determination with the Title Arbitrator prior to any written notice of determination hereunder being delivered by the Title Arbitrator.

(iv) The Title Arbitrator’s determination shall be in writing and shall be made within 20 days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Title Arbitrator shall be bound by the rules set forth in Section 13.2(g) and Section 13.2(h) and, subject to the foregoing, may consider only those materials described in Section 13.2(j)(iii), and shall choose either Upstream Seller’s position or Buyer’s position with respect to each matter addressed in a Title Dispute, based on the materials described above. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defect, Title Benefit, Title Defect Amounts, Title Benefit Amounts, and/or curative efforts submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter. Upstream Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each of Upstream Seller and Buyer shall bear one-half of the costs and expenses of the Title Arbitrator.

(v) Upon the later of the Title Arbitrator’s determination of all Title Disputes submitted to the Title Arbitrator for determination or the Parties’ agreement as to the resolution of such Title Dispute and the Environmental Arbitrator’s determination of all Environmental Disputes submitted to the Environmental Arbitrator for determination or the Parties’ agreement as to the resolution of such Environmental Disputes, then, with respect to the Title Defect Property subject to such Title Dispute, if (A) the Parties had elected (or were deemed to have elected) the remedy in Section 13.2(d)(i), then within ten Business Days after the Title Arbitrator delivers written notice to Buyer and Upstream Seller of its award

with respect thereto (or the Parties otherwise agree as to the resolution of such Title Dispute), and subject to Section 13.2(i), Buyer and Upstream Seller shall deliver joint written instructions to the Escrow Agent to deliver out of the applicable Closing Date Title Escrow Amount (1) to Upstream Seller the amount, if any, so awarded by the Title Arbitrator to Upstream Seller with respect to such Title Dispute (or as agreed by the Parties with respect thereto) and (2) to Buyer the amount, if any, so awarded by the Title Arbitrator to Buyer with respect to such Title Dispute (or as agreed by the Parties with respect thereto), (B) the Parties had elected the remedy in Section 13.2(d)(ii), then the Parties shall use commercially reasonable efforts to enter into the applicable Title Indemnity Agreement within ten Business Days after the Title Arbitrator delivers written notice to Buyer and Upstream Seller of his decision with respect thereto (or the Parties otherwise agree as to the resolution of such Title Dispute) and upon execution of such Title Indemnity Agreement Buyer and Upstream Seller shall deliver joint written instructions to the Escrow Agent to deliver out of the Closing Date Title Escrow Amount to Upstream Seller an amount equal to the Allocated Value of the applicable Title Defect Property the Title Defect Amount claimed by Buyer in good faith in the applicable Title Defect Notice applicable to such Title Defect, or (C) the Parties (or Upstream Seller, as permitted under Section 13.2(d)) had elected the remedy in Section 13.2(d)(iii), then within ten Business days after the Title Arbitrator delivers written notice to Buyer and Upstream Seller of his decision with respect thereto (or the Parties otherwise agree as to the resolution of such Title Dispute), the Parties (or Upstream Seller, as permitted under Section 13.2(d), as applicable) shall once against elect between the remedies in Section 13.2(d) pursuant to the terms thereof, mutatis mutandis, and (1) clause (A) or (B) of this Section 13.2(j)(v) shall apply, as applicable, or (2) if Section 13.2(d)(iii) is applicable with respect to such Title Defect Property, Buyer and Upstream Seller shall deliver joint written instructions to the Escrow Agent to deliver out of the Closing Date Title Escrow Amount to Buyer an amount equal to the Allocated Value of the applicable Title Defect Property and Seller shall continue to retain the applicable Title Defect Property and associated Upstream Assets. Disbursements from the Environmental Escrow Amount pursuant to this Section 13.2(j)(v) shall be made giving effect to Section 13.2(j)(ii) and Section 14.1(e)(ii) so as to achieve the same result as if the matters submitted to the Environmental Arbitrator for determination and to the Title Arbitrator for determination had been resolved prior to Closing on the same basis as resolved pursuant to this Section 13.2(j) and Section 14.1(f).

(vi) Except as provided in the proviso of Section 4.4, nothing herein shall operate to cause the Closing to be delayed on account of any arbitration hereunder and to the extent any adjustments are not agreed upon by the Parties as of the Closing, the Purchase Price shall be adjusted therefor as of the Closing by the Closing Date Title Escrow Amount as provided in this Section 13.2(j) and subsequent adjustments thereto will be made pursuant to Section 3.5 and this Section 13.2.

13.3 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 (i) production of Hydrocarbons through normal depletion (including watering out of any Well, collapsed casing or sand infiltration of any Well) and (ii) the depreciation of personal property due to ordinary wear and tear, in each case, with respect to the Assets.

(b) If, after the Execution Date but prior to the Closing Date, subject to Section 13.3(c), any portion of the Assets is damaged or destroyed or otherwise impaired by fire, explosion, tornado, hurricane, earthquake, earth movement, flood, water damage or other similar casualty or is taken in condemnation or under right of eminent domain (in each case, a “Casualty Loss”), then Buyer shall nevertheless be required to close the transactions contemplated by the Agreement and Seller shall elect by written notice to Buyer prior to Closing either to (i) cause the Assets affected by such Casualty Loss to be repaired or restored to at least its condition prior to such Casualty Loss, at Seller’s sole cost, as promptly as reasonably practicable

(which work may extend after the Closing Date) or (ii) pay to Buyer all sums paid to Seller by Third Parties by reason of such Casualty Loss affecting the Assets and assign, transfer and set over to Buyer or subrogate Buyer to (in the case of any such rights held by Seller outside of the Partnership) all of Seller’s right, title and interest (if any) in insurance claims, unpaid awards and other rights against Third Parties (excluding any Liabilities, other than insurance claims, of or against any Seller Indemnified Parties) arising out of such Casualty Loss affecting the Assets; provided, however, that if the Casualty Loss affected the Upstream Assets, Seller shall reserve and retain (and Buyer shall assign to Seller) all rights, title, interests and claims against Third Parties for the recovery of Seller’s costs and expenses incurred prior to the Closing in pursuing or asserting any such insurance claims or other rights against Third Parties with respect to any such Casualty Loss. If Seller elects the option in item (i) above, Seller shall retain (or, if such rights are held by the Partnership, Seller and Buyer shall cause the Partnership to assign to Seller) all rights to insurance, condemnation awards and other claims against Third Parties with respect to the casualty or taking except to the extent the Parties otherwise agree in writing.

(c) If, after the Execution Date but prior to the Closing Date, (i) all or any portion of the Gas Plants are destroyed or damaged by fire, explosion, tornado, hurricane, earthquake, earth movement, flood, water damage, sabotage, accident or other casualty (all of which are herein called “Midstream Casualty Loss”), (ii) the Gas Plants (or portions thereof) affected thereby have not, prior to the Closing Date, been replaced or repaired in all material respects to the condition of such Midstream Assets immediately prior to such Midstream Casualty Loss and placed into such operational condition and capability as such Midstream Assets were in immediately prior to such Midstream Casualty Loss, and (iii) such Midstream Casualty Loss could reasonably be expected to materially and adversely affect the ability of Buyer and the Partnership following the Closing to operate the Midstream Business in the ordinary course of business consistent with past practice for a period that is longer than 120 days after the Closing, then Buyer may terminate this Agreement pursuant to Section 7.1(f).

(d) Seller shall give Buyer prompt notice of any Casualty Loss or Midstream Casualty Loss of which Seller becomes aware. Seller shall not voluntarily compromise, settle or adjust any amounts payable by reason of any Casualty Loss or Midstream Casualty Loss without first obtaining the written consent of Buyer, which consent may not be unreasonably withheld or delayed.

13.4 Consents; Preferential Rights.

(a) Seller, on or prior to the later of (x) ten Business Days after the Execution Date, and (y) five Business Days after the Assignment Drop Dead Date, shall send to each holder of a Consent set forth in Schedule 9.4 a notice seeking such holder’s consent to the transactions contemplated hereby. With respect to any Consent that is not set forth on Schedule 9.4 (including those Consents not required to be set forth on such Schedule) but is discovered by any Party prior to Closing, Seller shall send to the holder of each such Consent a notice seeking such holder’s consent to the transactions contemplated hereby as soon as reasonably practicable after discovery of such Consent. Seller shall use its commercially reasonable efforts to obtain all Consents pursuant to the terms of this Agreement (provided that Seller shall not be obligated to incur any Liability to obtain any such Consent), and Buyer agrees to use its commercially reasonable efforts to cooperate with any such efforts (provided that Buyer shall not be obligated to incur any Liability (other than, as of the Closing, the Upstream Assumed Obligations) to obtain any such Consent; provided, further, however, that such restriction shall not be viewed to limit Buyer’s obligation to post any credit support or other similar consideration that may be expressly contemplated and/or called for pursuant to the terms of any Applicable Contract, Lease or Upstream Easement, including the Firm Transportation Agreements).

(i) If Seller fails to obtain a Hard Consent, then, in each such case, the affected Upstream Asset(s) shall be excluded from the Upstream Assets to be acquired by Buyer at Closing hereunder, and the Purchase Price shall be reduced by the Allocated Value of the Upstream Asset(s) so excluded. Following Closing, Seller shall use its commercially reasonable efforts to obtain each such Hard Consent (provided that Seller shall not be obligated to incur any Liabilities to obtain any such Consent). In the event that a Hard Consent (with respect to any applicable Upstream Asset(s) excluded pursuant to this Section 13.4(a)(i)) that was not obtained prior to Closing is obtained within 180 days following Closing, Seller shall promptly notify Buyer of such fact, and Buyer shall purchase, within ten days after such notification, such Upstream Asset(s) so excluded from Upstream Seller under the terms of this Agreement for the amount by which the Purchase Price was reduced at Closing due to the exclusion of such Upstream Asset(s) (as such amount is appropriately adjusted in accordance to Section 3.3 with respect to such Upstream Asset(s)), and Upstream Seller shall assign to Buyer such Upstream Asset(s) pursuant to an assignment in form substantially similar to the Upstream Assignment.

(ii) If Seller fails to obtain a Consent other than a Hard Consent prior to the Closing, then (x) the Upstream Asset(s) subject to such un-obtained Consent shall nevertheless be acquired by Buyer at Closing as part of the Upstream Assets or indirectly through the acquisition of the Midstream Interests, (y) Buyer shall have no claim against, and hereby releases and indemnifies the Seller Indemnified Parties from any Liability for, the failure to obtain such Consent, and (z) Buyer shall be solely responsible from and after the Closing for any and all Liabilities arising from the failure to obtain such Consent as part of the Upstream Assumed Obligations hereunder.

(b) With respect to each Preferential Purchase Right set forth on Schedule 9.4, Seller, on or prior to the later of (x) ten Business Days after the Execution Date, and (y) five Business Days after the Assignment Drop Dead Date, shall send to the holder of each such Preferential Purchase Right a notice in compliance with the contractual provisions applicable to such Preferential Purchase Right requesting a waiver of such right. With respect to each Preferential Purchase Right that is not set forth on Schedule 9.4 but is discovered by any Party prior to Closing, Seller shall send to the holder of each such Preferential Purchase Right a notice in compliance with the contractual provisions applicable to such Preferential Purchase Right requesting a waiver of such right as soon as reasonably practicable after discovery of any such Preferential Purchase Right. Any Preferential Purchase Right must be exercised subject to all terms and conditions set forth in this Agreement, and the consideration payable under this Agreement for the purposes of all Preferential Purchase Right notices shall be the Allocated Value of the applicable Upstream Asset (as adjusted herein).

(i) If, prior to Closing, any holder of a Preferential Purchase Right has consummated the acquisition of the Upstream Assets to which its Preferential Purchase Right applies, then the Upstream Assets subject to such Preferential Purchase Right shall be excluded from the Upstream Assets to be assigned to Buyer at Closing (and shall be considered Excluded Assets hereunder, but only to the extent of the portions of such Upstream Assets affected by the Preferential Purchase Right), and the Purchase Price shall be reduced by the Allocated Value of such Upstream Assets (or portions thereof) so excluded. Seller shall be entitled to all consideration given by any Person consummating the acquisition of any Upstream Assets subject to any Preferential Purchase Right prior to Closing.

(ii) If, as of Closing, (A) any holder of a Preferential Purchase Right has not waived such Preferential Purchase Right, (B) the period to exercise such Preferential Purchase Right has not expired without exercise or waiver thereof, or (C) any holder of a Preferential Purchase Right has not consummated the acquisition of the Upstream Assets to which its Preferential Purchase Right applies, then, in each case, the Upstream Assets subject to such Preferential Purchase Right shall be excluded from the Upstream Assets to be assigned to Buyer at Closing (and shall be considered Excluded Assets hereunder, but only to the extent

of the portions of such Upstream Assets affected by the Preferential Purchase Right), and the Purchase Price shall be reduced by the Allocated Value of such Upstream Assets (or portions thereof) so excluded.

(iii) If, following the Closing, any holder of a Preferential Purchase Right with respect to assets excluded from the Upstream Assets to be assigned to Buyer pursuant to Section 13.4(b)(ii) fails to validly exercise such right prior to the expiration of the exercise period applicable to such Preferential Purchase Right or fails to consummate the acquisition of the Upstream Assets to which such holder’s Preferential Purchase Right was exercised (prior to or after the Closing), Seller shall promptly notify Buyer of such failure, and Buyer shall purchase, within ten days after such notification, such Upstream Asset(s) so excluded from Upstream Seller under the terms of this Agreement for the amount by which the Purchase Price was reduced at Closing due to the exclusion of such Upstream Asset(s) (as such amount is appropriately adjusted in accordance to Section 3.3 with respect to such Upstream Asset(s)), and Upstream Seller shall assign to Buyer such Upstream Asset(s) pursuant to an assignment in form substantially similar to the Upstream Assignment and deliver any other instruments and documents that would have been required under the terms of this Agreement to be delivered at the Closing with respect to such Upstream Asset(s).

ARTICLE XIV

ENVRIONMENTAL MATTERS

14.1 Notice of Environmental Defects.

(a) Environmental Defect Notices. If Buyer discovers any Environmental Condition which, in its reasonable opinion, Buyer determines constitutes an Environmental Defect, Buyer shall promptly notify Upstream Seller within five Business Days of such discovery and, in any event, on or before the Defect Claims Date. To be effective, notice of an Environmental Defect (an “Environmental Defect Notice”) shall be in writing and shall include (i) a reasonable description of the Environmental Condition constituting, in Buyer’s reasonable opinion, Environmental Defect(s), (ii) the identity of the Upstream Asset(s) (including, with respect to a Well or Well Location, a reasonable description of such Well or Well Location and the Leases(s) contributing to such Well or Well Location) or portions thereof, affected by the asserted Environmental Defect (each, an “Environmental Defect Property”), (iii) supporting documentation available to Buyer reasonably necessary for Seller to verify the existence of the alleged Environmental Defect, including, to the extent permitted by Seller under Section 12.1, any physical measurements or lab analyses or photographs, (iv) the Allocated Value of each Environmental Defect Property, (v) the Remediation Amount (itemized in reasonable detail) that Buyer asserts is attributable to such Environmental Defect and the computations and information upon which Buyer’s belief is based, (vi) a reasonable description of the Remediation proposed for the Environmental Condition that gives rise to the asserted Environmental Defect, and (vii) a reasonable description of the violation of Environmental Law that gives rise to such Environmental Defect. For all purposes of this Agreement but subject to Buyer’s remedy for a breach of Seller’s representation contained in Section 9.14 and Buyer’s remedies for breaches of the covenants of Seller set forth in Section 11.1(a)(i) (as so limited by Section 11.1(c)), Buyer shall be deemed to have waived, and Seller shall have no liability for, any Environmental Defect which Buyer fails to assert as an Environmental Defect by an Environmental Defect Notice meeting the requirements of this Section 14.1(a) that is received by Upstream Seller on or before the Defect Claims Date.

(b) Upstream Seller’s Right to Remediate. Upstream Seller shall have the right, but not the obligation, to attempt, at its sole cost, to Remediate, at any time prior to the Closing, any Environmental Defects of which Upstream Seller has been advised by Buyer. An election by Upstream Seller to Remediate an Environmental Defect shall be without prejudice to its rights under Section 14.1(f) and shall not constitute

an admission against interest or a waiver of Upstream Seller’s right to dispute the existence, nature or value of, or cost to Remediate, the alleged Environmental Defect.

(c) Remedies for Environmental Defects. Subject to (x) Upstream Seller’s continuing right to dispute the existence of an Environmental Defect and/or the Remediation Amount asserted with respect thereto, (y) Upstream Seller’s remediation rights pursuant to Section 14.1(b), and (z) the rights of the Parties pursuant to Section 7.1(d), in the event that any Environmental Defect properly asserted by Buyer in accordance with Section 14.1(a) is not waived in writing by Buyer or Remediated on or before the Closing, then, subject to the Individual Environmental Defect Threshold and the Defect Deductible, the Parties shall mutually agree to resolve Environmental Defects as follows:

(i) reduce the Purchase Price by the Remediation Amount determined pursuant to Section 14.1(f) or other provision of this Agreement;

(ii) Upstream Seller shall retain responsibility for the Remediation of such Environmental Defect and Upstream Seller shall indemnify Buyer against all Liability resulting from such Environmental Defect pursuant to an indemnity agreement in form and substance reasonably satisfactory to the Parties (each, an “Environmental Indemnity Agreement”);

(iii) Upstream Seller shall retain the entirety of such Environmental Defect Property and all associated Upstream Assets, in which event the Purchase Price shall be reduced at Closing by an amount equal to the Allocated Value of such Environmental Defect Property and such associated Upstream Assets, and such Environmental Defect Property and associated Upstream Assets shall be treated as Excluded Assets under this Agreement; or

(iv) Buyer shall assume the responsibility for the Remediation of the Environmental Defect, and Upstream Seller shall indemnify Buyer against all Liability resulting from such Environmental Defect up to the Allocated Value of the applicable Environmental Defect Property pursuant to an Environmental Indemnity Agreement;

In the event that the Parties do not agree in writing by Closing on an election of alternative (i), (ii), (iii) or (iv) above with respect to any Environmental Defect, the Parties shall be deemed to have elected alternative (i) with respect to such Environmental Defect, subject to Section 14.1(f); provided that if the Remediation Amount associated with an Environmental Defect Property as asserted by Buyer (after giving effect to any reduction thereof as agreed to by Buyer due to efforts by Seller prior to Closing to cure such Environmental Defect) equals or exceeds the Allocated Value of such Environmental Defect Property, then Upstream Seller may elect alternative (iii) with respect to such Environmental Defect Property.

If the Parties elect (or are deemed to have elected) alternative (i) above, Buyer shall be deemed to have assumed responsibility for all of the costs and expenses attributable to the Remediation of the Environmental Condition attributable to such Environmental Defect and such responsibility of Buyer shall be deemed to constitute part of the Upstream Assumed Obligations hereunder. If the Parties elect alternative (ii) above, Upstream Seller shall use reasonable efforts to implement such Remediation in a manner which is consistent with the requirements of Environmental Laws in a timely fashion for the type of Remediation that Seller elects to undertake and Buyer, effective as of the Closing, grants to Seller and its Representatives, access to the Upstream Assets and all utilities located on the Upstream Assets as may be reasonably required in order to conduct such Remediation.

(d) Exclusive Remedy. Except for Buyer’s rights (i) under Section 8.2(a) for a breach of Seller’s representations and warranties set forth in Section 9.14, (ii) under Section 8.2(b) for a breach of the covenants of Seller set forth in Section 11.1(a)(i) and (iii) to terminate this Agreement pursuant to Section 7.1(d), the provisions set forth in Section 14.1(c) shall be the exclusive right and remedy of Buyer with respect to any Environmental Defect or any other environmental matter with respect to any Asset.

(e) Threshold and Deductible. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any individual Environmental Defect for which the Remediation Amount does not exceed $100,000 (“Individual Environmental Defect Threshold”); and (ii) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any Environmental Defect for which the Remediation Amount exceeds the Individual Environmental Defect Threshold unless (A) the sum of (1) the Remediation Amounts of all such Environmental Defects that exceed the Individual Environmental Defect Threshold (excluding any Environmental Defects Remediated by Upstream Seller or retained by Upstream Seller pursuant to Section 14.1(c)(iii))), plus (2) all Title Defect Amounts of all Title Defects that exceed the Individual Title Defect Threshold (excluding any Title Defects cured by Upstream Seller or retained by Upstream Seller pursuant to Section 13.2(d)(iii))), minus (3) all Title Benefit Amounts, exceeds (B) the Defect Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price or other remedies only with respect to such Environmental Defects relating to Remediation Amounts in excess of the Defect Deductible. For the avoidance of doubt, the Individual Environmental Defect Threshold is a threshold and shall not be applied as a deductible if the amount of such Individual Environmental Defect Threshold is exceeded by the applicable Remediation Amount. For the avoidance of doubt, if Upstream Seller indemnifies Buyer with respect to any Environmental Defect Property pursuant to an Environmental Indemnity Agreement or retains any Environmental Defect Property pursuant to Section 14.1(c)(iii), then, in each case, after such election, the Remediation Amount relating to such Environmental Defect Property will not be counted towards the Defect Deductible. This Section 14.1(e) shall be applied in this Agreement without giving duplicative effect to its application under this Section 14.1 and Section 13.2.

(f) Environmental Dispute Resolution.

(i) Upstream Seller and Buyer shall undertake commercially reasonable efforts to agree (A) to all Environmental Defect and Remediation Amounts prior to Closing and (B) whether or not any Environmental Defect that Upstream Seller elects to Remediate prior to Closing pursuant to Section 14.1(b) has been Remediated (or if not so cured the Remediation Amount applicable thereto) by the Closing (each such matter to which the Parties do not agree, an “Environmental Dispute”). If Upstream Seller and Buyer are unable to agree by the Closing Date on any Environmental Dispute (including any efforts by Seller prior to Closing to Remediate any Environmental Defect), then (1) such Environmental Dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 14.1(f), subject to the proviso of Section 4.4, (2) an amount equal to the sum of (x) if the Parties had elected (or were deemed to have elected) the remedies set forth in Section 14.1(c)(i), Section 14.1(c)(ii), or Section 14.1(c)(iv) with respect to the applicable Environmental Defect, the Remediation Amount claimed by Buyer in good faith in the applicable Environmental Defect Notice applicable to such Environmental Dispute, and (y) if the Parties (or Upstream Seller, as permitted under Section 14.1(c)) had elected the remedy set forth in Section 14.1(c)(iii) with respect to the applicable Environmental Defect, the Allocated Value of the Upstream Assets subject to such Environmental Dispute, subject to Section 14.1(e) (such amount, as determined in the aggregate with respect to all applicable Environmental Disputes, the “Closing Date Environmental Escrow Amount”) will be deposited by Buyer with the Escrow Agent to be held pursuant to the Escrow Agreement and Section 14.1(f)(v) and (3) the Purchase Price will be reduced at Closing by the Closing Date Environmental Escrow Amount. For the avoidance of doubt, the Upstream Assets subject to any Environmental Dispute shall be

conveyed to Buyer at Closing pursuant to the Assignment unless (X) the Parties (or Upstream Seller, as permitted under Section 14.1(c)) elect the remedy set forth in Section 14.1(c)(iii) with respect to any Environmental Dispute or (Y) the Remediation Amount asserted by Buyer in the applicable Environmental Defect Notice applicable to such Environmental Dispute equals or exceeds the Allocated Value of such Environmental Defect Property such that the Parties (or Upstream Seller, as permitted under Section 14.1(c)) may, upon final determination of the Environmental Dispute, elect the remedy set forth in Section 14.1(c)(iii) with respect to such Environmental Dispute if, as determined by the Environmental Arbitrator, the Remediation Amount equals or exceeds the Allocated Value of such Environmental Defect Property, in either case of (X) or (Y), such Upstream Assets shall be retained by Upstream Seller at Closing.

(ii) There shall be a single arbitrator, who shall be an environmental consultant with at least ten years’ experience in environmental matters involving oil and gas producing properties in the regional area in which the affected Upstream Assets are located, as selected by mutual agreement of Buyer and Upstream Seller within 15 days after the Closing Date (the “Environmental Arbitrator”). In the event the Parties are unable to mutually agree upon the Environmental Arbitrator within such time period, then either Party may petition the AAA to select a neutral party who has never been an officer, director or employee of or performed material work for the Parties or any of their Affiliates within the preceding five year period as Environmental Arbitrator, with due regard given to the selection criteria above and input from the Parties. In the event the AAA should fail to select the Environmental Arbitrator within 90 days from initiation of arbitration, then either party to the Environmental Dispute may petition any United States District Judge for the District of Colorado to select the Environmental Arbitrator. The arbitration proceeding shall be held in Denver, Colorado.

(iii) Within ten Business Days after the selection of the applicable Environmental Arbitrator, the Parties shall provide to such Environmental Arbitrator (A) each Environmental Defect Notice and all documentation provided therewith with respect to each disputed Environmental Defect; and (B) such evidence as Seller deems appropriate to explain and dispute the existence, waiver and cure of each disputed Environmental Defect or the Remediation Amount assigned thereto by Buyer in any Environmental Defect Notice, together with Seller’s good faith estimate of the Remediation Amount, if any, with respect to each such disputed Environmental Defect. Each of Buyer and Seller also shall furnish to the Environmental Arbitrator such workpapers and other documents and information relating to each Environmental Dispute as the Environmental Arbitrator may request and are available to that Party or its Affiliates, and each of buyer and Seller will be afforded the opportunity to present to the Environmental Arbitrator any material relating to each Environmental Dispute as such Party shall deem appropriate to support its position with respect to each such matter and to discuss such determination with the Environmental Arbitrator prior to any written notice of determination hereunder being delivered by the Environmental Arbitrator.

(iv) The Environmental Arbitrator’s determination shall be in writing and shall be made within 20 days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Environmental Arbitrator shall be bound by the rules set forth in this Section 14.1 and, subject to the foregoing, may consider only those materials described in Section 14.1(f)(iii), and shall choose either Upstream Seller’s position or Buyer’s position with respect to each matter addressed in an Environmental Dispute, based on the materials described above. The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defects, Remediation Amounts, and/or curative efforts submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter. Upstream Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each of Upstream Seller and Buyer shall bear one-half of the costs and expenses of the Environmental Arbitrator.

(v) Upon the later of the Environmental Arbitrator’s determination of all Environmental Disputes submitted to the Environmental Arbitrator for determination or the Parties’ agreement as to the resolution of such Environmental Disputes and the Title Arbitrator’s determination of all Title Disputes submitted to the Title Arbitrator for determination or the Parties’ agreement as to the resolution of such Title Dispute, then, with respect to the Environmental Defect Property subject to such Environmental Dispute, if (A) the Parties had elected (or were deemed to have elected) the remedy in Section 14.1(c)(i), then within ten Business Days after the Environmental Arbitrator delivers written notice to Buyer and Seller of his decision with respect thereto (or the Parties otherwise agree as to the resolution of such Environmental Dispute), and subject to Section 14.1(e), Buyer and Upstream Seller shall deliver joint written instructions to the Escrow Agent to deliver out of the Closing Date Environmental Escrow Amount (1) to Upstream Seller the amount, if any, so awarded by the Environmental Arbitrator to Upstream Seller with respect to such Environmental Dispute (or as agreed by the Parties with respect thereto) and (2) to Buyer the amount, if any, so awarded by the Environmental Arbitrator to Buyer with respect to such Environmental Dispute (or as agreed by the Parties with respect thereto), (B) the Parties had elected the remedy in Section 14.1(c)(ii) or Section 14.1(c)(iv), then the Parties shall use commercially reasonable efforts to enter into the applicable Environmental Indemnity Agreement within ten Business Days after the Environmental Arbitrator delivers written notice to Buyer and Upstream Seller of his decision with respect thereto (or the Parties otherwise agree as to the resolution of such Environmental Dispute), and after entering into such Environmental Indemnity Agreement the applicable Party shall assume responsibility to Remediate the applicable Environmental Defect and Buyer and Upstream Seller shall deliver joint written instructions to the Escrow Agent to deliver out of the Closing Date Environmental Escrow Amount to Upstream Seller an amount equal to the Remediation Amount claimed by Buyer in good faith in the applicable Environmental Defect Notice applicable to such Environmental Dispute, or (C) the Parties (or Upstream Seller, as permitted under Section 14.1(c)) had elected the remedy in Section 14.1(c)(iii), then within ten Business Days after the Environmental Arbitrator delivers written notice to Buyer and Upstream Seller of his decision with respect thereto (or the Parties otherwise agree as to the resolution of such Environmental Dispute), Upstream Seller and Buyer shall once again elect between the remedies in Section 14.1(c) pursuant to the terms thereof, mutatis mutandis, and (1) clause (A) or (B) of this Section 14.1(f)(v) shall apply, as applicable, or (2) if Section 14.1(c)(iii) is applicable with respect to such Environmental Defect Property, Buyer and Upstream Seller shall deliver joint written instruction to the Escrow Agent to deliver out of the Closing Date Environmental Escrow Amount to Buyer an amount equal to the Allocated Value of the applicable Environmental Defect Property and Upstream Seller shall continue to retain the applicable Environmental Defect Property and associated Upstream Assets. Disbursements from the Environmental Escrow Amount pursuant to this Section 14.1(f)(v) shall be made giving effect to Section 13.2(j)(ii) and Section 14.1(e)(ii) so as to achieve the same result as if the matters submitted to the Environmental Arbitrator for determination and to the Title Arbitrator for determination had been resolved prior to Closing on the same basis as so resolved pursuant to this Section 14.1(f) and Section 13.2(j).

(vi) Except as provided in the proviso of Section 4.4, nothing herein shall operate to cause the Closing to be delayed on account of any arbitration hereunder and to the extent any adjustments are not agreed upon by the Parties as of the Closing, the Purchase Price shall be adjusted therefor as of the Closing by the Closing Date Environmental Escrow Amount as provided in this Section 14.1(f) and subsequent adjustments thereto will be made pursuant to Section 3.5 and this Section 14.1.

14.2 NORM, Wastes and Other Substances. Buyer acknowledges that the Assets have been used for exploration, development, production, gathering and transportation of oil and gas and there may be petroleum, produced water, wastes or other substances or materials located in, on or under the Assets or associated with the Assets.

ARTICLE XV

MISCELLANEOUS

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

15.2 Expenses and Taxes.

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

(b) All required documentary, filing and recording fees and expenses in connection with the filing and recording of the assignments (including the Assignment), conveyances or other instruments required to convey title to the Assets and Partnership Interests to Buyer shall be borne by Buyer. Buyer shall assume responsibility for, and shall bear and pay, all state sales and use Taxes and transfer and similar Taxes (including any applicable interest or penalties) incurred or imposed with respect to the transactions described in this Agreement other than the Conversion (the “Transfer Taxes”). 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.

(i) Seller shall be allocated and bear all Asset Taxes attributable to (A) any Tax period ending prior to the Effective Time and (B) the portion of any Straddle Period ending immediately prior to the Effective Time;

(ii) Seller shall be allocated and bear all Income Taxes payable by the Partnership attributable to (A) any Tax period ending on the Closing Date and (B) the portion of any Straddle Period ending on the Closing Date;

(iii) Buyer shall be allocated and bear all Asset Taxes attributable to (A) any Tax period beginning at or after the Effective Time and (B) the portion of any Straddle Period beginning at the Effective Time; and

(iv) Buyer shall be allocated and bear all Income Taxes payable by the Partnership attributable to (1) any Tax period beginning after the Closing Date and (2) the portion of any Straddle Period beginning after the Closing Date.

(d) For purposes of determining the allocations described in Section 15.2(c), (i) Asset Taxes that are attributable to the severance or production of Hydrocarbons (other than such Asset Taxes described in clause (iii), below) shall be allocated to the period in which the severance or production giving rise to such Asset Taxes occurred, (ii) Asset Taxes that are based upon or related to sales or receipts or imposed on a transactional basis (other than such Asset Taxes described in clause (i) or (iii)), shall be allocated to the period in which the transaction giving rise to such Asset Taxes occurred, (iii) Asset Taxes that are ad valorem, property or other Asset Taxes imposed on a periodic basis pertaining to a Straddle Period shall be allocated between the portion of such Straddle Period ending immediately prior to the Effective Time and the portion of such Straddle Period beginning at the Effective Time by prorating each such Asset Tax based on the number of days in the applicable Straddle Period that occur before the date on which the Effective Time occurs, on the one hand, and the number of days in such Straddle Period that occur on or after the date on which the Effective Time occurs, on the other hand, and (iv) Income Taxes payable by the Partnership shall be allocated between the portion of such Straddle Period ending on the Closing Date and the portion of such Straddle Period beginning after the Closing Date as if the taxable year of the Partnership ended on the Closing Date. To the extent the Partnership is included in a combined Texas franchise tax report with Seller or an Affiliate of Seller, the allocation provided in this Section 15.2(d) shall be calculated as if the Partnership left the combined group immediately after the Closing Date.

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

(f) Subject to Buyer’s right to reimbursement pursuant to Section 15.2(e), Buyer shall (i) pay any Asset Taxes relating to any Tax period that ends before or includes the Closing Date that become due and payable after the Closing Date and file with the appropriate Taxing Authority any and all Tax Returns required to be filed after the Closing Date with respect to such Asset Taxes, (ii) submit each such Tax Return to Seller for its review and comment reasonably in advance of the due date therefor, and (iii) timely file any such Tax Return, incorporating any comments received from Seller prior to the due date therefor. The Parties agree that (x) this Section 15.2(f) is intended to solely address the timing and manner in which certain Tax Returns relating to Asset Taxes are filed and the Asset Taxes shown thereon are paid to the applicable Taxing Authority, and (y) nothing in this Section 15.2(f) shall be interpreted as altering the manner in which Asset Taxes are allocated to and economically borne by the Parties (except for any penalties, interest or additions to Tax imposed as a result of any breach by Buyer of its obligations under this Section 15.2(f), which shall be borne by Buyer).

(g) Seller shall prepare and file all Tax Returns of the Partnership for any period ending on or before the Closing Date. Buyer shall prepare and file all Tax Returns of the Partnership for any Straddle Period that are due after the Closing Date. The Party preparing any such Tax Return (other than any Tax

Return with respect to Income Taxes of the Partnership for any period ending on or before the Closing Date) shall (1) submit to the other Party each such Tax Return for its review and comment reasonably in advance of the due date therefor, (2) consider, in good faith, any comments to such Tax Return and (3) shall pay any Taxes shown as due and payable thereon subject to its right to reimbursement pursuant to Section 15.2(e).

(h) The amount of any refunds or credits of (i) Income Taxes of the Partnership for any Tax period ending on the Closing Date, or the portion of any Straddle Period ending on the Closing Date and (ii) other Taxes of the Partnership for any Tax period ending before the Effective Time or the portion of any Straddle Period ending immediately before the Effective Time, shall in each case be for the account of Seller except to the extent such refunds or credits were taken into account as an adjustment to the Purchase Price pursuant to Section 3.3, Section 3.4 and Section 3.5, as applicable. The amount of any refunds or credits of (A) Income Taxes of the Partnership for any Tax period beginning after the Closing Date, or the portion of any Straddle Period beginning after the Closing Date and (B) other Taxes of the Partnership for any Tax period beginning at the Effective Time or the portion of any Straddle Period beginning at the Effective, Time shall in each case be for the account of Buyer. The amount of any refund or credit of Taxes of the Partnership for any Straddle Period shall be equitably apportioned between Buyer and Seller in accordance with the principles set forth in Section 15.2(c), 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 15.2(h) the amount of such refund within 30 days after such refund is received or credit is realized, net of any reasonable third-party costs or expenses incurred by such Party or its Affiliates in procuring such refund or credit.

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

(j) After the Closing, Buyer shall control the conduct of any audit, adjustment, claim, examination, assessment, contest, or other proceeding with respect to Asset Taxes or any Taxes payable by the Partnership (each a “Tax Audit”). In the case of a Tax Audit after the Closing that could reasonably be expected to result in a liability to Seller under this Agreement or otherwise, (A) Buyer shall keep Seller reasonably informed and consult with Seller with respect to any material issue relating to such Tax Audit, (B) Buyer shall provide Seller copies of all correspondence, notices and other written material received from any Governmental Authority with respect to such Tax Audit, (C) Buyer shall provide Seller with a copy of, and an opportunity to review and comment on, all submissions made to a Governmental Authority in connection with such Tax Audit, and (D) Buyer shall not agree to a settlement or compromise thereof without the consent of Seller, which consent shall not be unreasonably withheld, delayed or conditioned. Notwithstanding the foregoing, the Parties expressly agree that any Tax Audit relating to U.S. federal income taxes of the Partnership conducted with respect to the taxable period ending on or prior to the date of the Conversion shall be controlled by Seller; provided, however, that in the event Buyer or its Affiliates or the Partnership would be subject to Liability (taking into account the Conversion) as a result of such Tax Audit, then (1) Seller shall not agree to compromise or settlement thereof without the prior written consent of Buyer (such consent not be unreasonable withheld, conditioned or delayed) and (2) Seller and the Partnership shall take all actions that may be reasonably necessary or appropriate to prevent the Partnership from having any liability for an “imputed underpayment” (within the meaning of Section 6225 of the Code) or any interest or penalty related thereto that is attributable to any adjustment of any item of income, gain, loss, deduction or credit of the Partnership for any taxable period or portion thereof ending on or prior to the date of the Conversion.

(k) The Parties acknowledge and agree that following the Conversion, the Partnership will be classified as a disregarded entity under Section 301.7701-3(b)(1)(ii) of the Treasury Regulations, and

both Buyer and Seller agree to report, for all applicable Tax reporting and compliance purposes, the transfer and sale of the Midstream Interests as a deemed asset sale for U.S. federal income tax purposes.

(l) The Parties shall cooperate fully, as and to the extent reasonably required in connection with the filing of any Tax Returns, the qualification for any exemption or reduction in Tax that may be available, State and Federal regulatory reports, royalty payments including related deduction and any audit, litigation or other proceeding with respect to these matters for the Assets. Such cooperation shall include the retention of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Buyer agrees to allow access (upon request) to the Assets by Seller, Seller’s Representatives, auditors and State or Federal representatives relevant to any such audit, litigation or other proceeding.

15.3 Assignment. This Agreement may not be assigned by Buyer or Seller without the prior written consent of the non-assigning Party; provided that (a) without the consent of Seller, but only upon prior written notice to Seller delivered on or before ten Business Days following the Execution Date (such date, or such earlier date as Buyer delivers such written notice (or written notice that it will not utilize such Affiliate assignment rights), the “Assignment Drop Dead Date”), Buyer may assign all or part of this Agreement to one or more Affiliates of Buyer, or (b) without the consent of Seller, Buyer may collaterally assign its rights under this agreement to the Financing Sources; provided that any such assignment shall not relieve Buyer of its obligations hereunder without Seller’s written consent. In the event the non-assigning Party consents to any such assignment, such assignment shall not relieve the assigning Party of any obligations and responsibilities hereunder. Any assignment or other transfer by Buyer or its successors and assigns of any of the Assets shall not relieve Buyer or its successors or assigns of any of their obligations (including indemnity obligations) hereunder, as to the Assets so assigned or transferred. Any assignment made in contravention of the terms of this Section 15.3 shall be void ab initio.

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

15.5 Publicity.

(a) If Buyer desires to make or issue any public announcement concerning the transactions contemplated by this Agreement, it shall first give Seller 24 hours written notification of its desire to make such a public announcement. The written notification shall include a written draft of the text of such public announcement. Seller shall be given the right to provide comments to the proposed public announcement, and Buyer shall use its reasonable efforts to incorporate such comments into such public announcement. Notwithstanding the foregoing, Buyer shall not make or issue any such public announcement within three Business Days after the Closing.

(b) If Seller desires to make a public announcement, it shall first give Buyer 24 hours written notification of its intention to make a public announcement. The written notification shall include a written draft of the text of such public announcement. Buyer shall be given the right to provide comments to the proposed public announcement, and Seller shall use its reasonable efforts to incorporate such comments into such public announcement. Subject to the Parties’ rights and obligations discussed in Section 15.5(c), in no event shall Seller disclose the identity of Buyer without the express written consent of Buyer.

(c) Nothing in this Section 15.5 shall prohibit any Party from issuing or making a public announcement or statement if such Party deems it necessary to do so in order to comply with any applicable Law or the rules of any stock exchange upon which the Party’s or a Party’s Affiliate’s capital stock is traded; provided, however, that to the extent not inadvisable in such Party’s reasonable discretion, prior written notification shall be given to the other Parties prior to any such announcement or statement.

(d) Notwithstanding anything to the contrary in this Section 15.5, from and after the date that Seller or its Affiliate makes a public announcement concerning the transactions contemplated by this Agreement, this Section 15.5 will not preclude or prevent or otherwise restrict the activities of the Financing Sources in connection with the Financings.
