PURCHASE AND SALE AGREEMENT

This PURCHASE AND SALE AGREEMENT (this “Agreement”) is dated as of January 3, 2011, by and between EQT Gathering, LLC, a Delaware limited liability company (“Seller”) and MarkWest Energy Appalachia, L.L.C., a Delaware limited liability company (“Buyer”). Seller and Buyer are referred to herein as the “Parties” and individually as a “Party.” Capitalized terms used but not otherwise defined elsewhere in this Agreement shall have the respective meanings given to such terms in ARTICLE XI.

A. Seller owns and operates certain Assets, including the Processing Facilities located near ▇▇▇▇▇▇▇ and Maytown, Kentucky, and the Ranger NGL Pipeline.

B. Seller desires to sell to Buyer (and/or a Buyer Subsidiary), and Buyer (and/or such Buyer Subsidiary) desires to purchase from Seller, the Assets, free and clear of all Liens other than Permitted Encumbrances, upon the terms and subject to the conditions set forth herein.

C. At the Closing of the transactions contemplated by this Agreement, EQT Energy, LLC, a Delaware limited liability company and Affiliate of Seller (“EQT Energy”), and Buyer will enter into the Gas Processing Agreement, whereby, among other things, Buyer will commit to continue to process EQT Energy’s Gas at the Processing Facilities and deliver Plant Products attributable thereto to the NGL Delivery Point in consideration of EQT Energy’s commitment to pay the Processing Fees described therein.

D. At the Closing of the transactions contemplated by this Agreement, EQT Energy and Buyer will enter into the NGL Exchange Agreement, whereby, among other things, Buyer will agree to complete the Ranger II NGL Pipeline described therein and exchange Plant Products attributable to EQT Energy’s Gas delivered by EQT Energy to the NGL Delivery Point located at the tailgate of the Processing Facilities for Fractionated Products delivered by Processor to the tailgate of the Siloam Fractionation Plant in consideration of EQT Energy’s commitment to pay the fees described therein.

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

ARTICLE I
SALE AND TRANSFER OF ASSETS

Section 1.1. Purchase and Sale.

(a) Upon the terms and subject to the conditions set forth in this Agreement, at the Closing, Seller shall sell, convey, assign, transfer and deliver to Buyer (and/or a Buyer Subsidiary), and Buyer (and/or such Buyer Subsidiary) shall purchase, acquire and accept from Seller, the Assets, free and clear of all

Liens other than Permitted Encumbrances, and assume the Assumed Liabilities with respect thereto, in consideration for which, Buyer (on its own behalf, or as applicable, as agent for a Buyer Subsidiary) will pay to Seller an amount equal to $230,000,000 (the “Unadjusted Purchase Price”), adjusted as provided in Section 1.3 (as adjusted, the “Purchase Price”).

(b) Seller shall retain, and shall be fully responsible for paying, performing and discharging when due, and Buyer (and/or any Buyer Subsidiary) shall not assume or have any responsibility for, any Retained Liability.

Section 1.2. Time and Place of Closing. Upon the terms and subject to the conditions of this Agreement, the closing of the transactions contemplated by this Agreement (the “Closing”) will take place at the offices of Seller, located at EQT Plaza, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, at 10:00 A.M. Eastern time on the first Business Day of the month following satisfaction or waiver of all of the conditions to the obligations of the parties set forth in ARTICLE VII (other than actions to be taken or items to be delivered at Closing, but subject to satisfaction of such conditions at the Closing); provided that there are at least 10 days between the satisfaction of such conditions and such date; provided further, that in the event there are less than 10 days between the satisfaction of such conditions and the first Business Day of the following month, the Closing will take place on the first Business Day of the second month following satisfaction of such conditions, or such date as the parties may mutually agree (the “Closing Date”).

Section 1.3. Adjustments to the Purchase Price.

(a) The Unadjusted Purchase Price shall be adjusted as follows:

(i) increased by an amount equal to the NGL Inventory Value for the volume of each of propane, isobutane, normal butane and natural gasoline included in the aggregate NGL volume, as of the Effective Time, in the Ranger NGL Pipeline, the stock tanks at the Ranger Truck Terminal and loaded in trucks for transport to the Ranger Truck Terminal or the Siloam Fractionation Plant;

(ii) increased by the net amount of all prepaid expenses (including prepaid Taxes) to the extent applying to the ownership and operation of the Assets following the Effective Time; and

(iii) decreased for costs or expenses, including Taxes (other than income, franchise and similar taxes), incurred with respect to the operation of the Assets prior to the Effective Time but paid by Buyer after the Effective Time.

Should Buyer or its Affiliates pay after the Effective Time any expenses for which Seller is responsible under this Section 1.3(a) and which have not been accounted

for in the final Closing Adjustment in accordance with Section 1.3(d), Seller shall reimburse Buyer (or its Affiliates, as applicable) promptly after receipt of such Person’s invoice, accompanied by copies of the relevant vendor or other invoice and proof of payment.

(b) For purposes of determining the amount of cash to be paid as the Estimated Purchase Price by Buyer to Seller at the Closing pursuant to Section 1.5(a), Seller shall prepare and deliver, not less than two Business Days before the Closing Date, a good faith estimate of each adjustment to be made pursuant to Section 1.3(a) (the “Closing Adjustment”) determined in accordance with the US GAAP (except as set forth in Section 1.3(c)) as of the Closing Date (such estimated adjustments, the “Estimated Closing Adjustment”), which shall be reasonably acceptable to Buyer. As used in this Agreement, the “Estimated Purchase Price” shall mean an amount equal to the Unadjusted Purchase Price plus an amount equal to the Estimated Closing Adjustment (which may be positive or negative).

(c) For purposes of determining the Estimated Closing Adjustment, Seller shall measure, determine or estimate in good faith, based upon historical inventory and volume lists provided by Seller to Buyer, the physical inventory and composition of the NGL volumes in the Ranger NGL Pipeline, the stock tanks at the Ranger Truck Terminal and loaded in trucks for transport to the Ranger Truck Terminal or the Siloam Fractionation Plant as of the Effective Time to determine the volume and composition of NGLs as near as possible to the Effective Time for purposes of the adjustment in Section 1.3(a)(i). The Parties agree that, notwithstanding the fact each location identified in Section 1.3(a)(i) has not been subject to a physical inventory as of the Effective Time, the physical inventory taken by Seller under this Section 1.3(b) shall constitute the NGL volumes included in the Assets and subject to adjustment in accordance with Section 1.3(b).

(d) As soon as reasonably practicable after the Closing but not later than the 60th day following the Closing Date, Seller shall prepare and deliver to Buyer a statement setting forth its calculation of the Purchase Price and the Closing Adjustment based on the most recent actual figures for each adjustment and determined in accordance with the US GAAP (the “Seller Closing Statement”). Seller shall at Buyer’s request make reasonable documentation available to Buyer and its representatives to support the information set forth in the Seller Closing Statement (including access to employees of Seller and supporting schedules, analyses, work papers and underlying records and documentation as are reasonably necessary or helpful in Buyer’s review of such statement). Seller shall provide all other cooperation reasonably requested by Buyer in connection with Buyer’s review of the Seller Closing Statement. As soon as reasonably practicable but not later than the 45th day following receipt of

Seller’s statement hereunder (the “Buyer Review Period”), Buyer may deliver to Seller a written report containing any changes that Buyer proposes be made to the Seller Closing Statement (the “Buyer Closing Statement”). Seller may deliver a written report to Buyer during this same period reflecting any changes that Seller proposes to be made in the Seller Closing Statement as a result of additional information received after the statement was prepared; provided that the Buyer Review Period shall be deemed to recommence upon any such delivery by Seller. The Parties shall use good faith efforts to agree on the final statement of the Purchase Price and the Closing Adjustment no later than 75 days after delivery of the Seller Closing Statement. In the event that the Parties hereto cannot reach agreement within such period of time, either Party may refer the items of the Closing Adjustment which are in dispute to Ernst & Young LLP or another nationally-recognized independent accounting firm or consulting firm mutually acceptable to the Parties (the “Accounting Arbitrator”), for review and final determination by arbitration. Should the initial Accounting Arbitrator fail or refuse to agree to serve as Accounting Arbitrator within 20 days after written request from any Party to serve, and the Parties fail to agree in writing on a replacement Accounting Arbitrator within 10 days after the end of that 20-day period, or should no replacement Accounting Arbitrator agree to serve within 45 days after the original written request pursuant to this sentence, the Accounting Arbitrator shall be appointed by the Philadelphia office of the American Arbitration Association. The Accounting Arbitrator shall conduct the arbitration proceedings in Pittsburgh, Pennsylvania in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section 1.3(d). The Accounting Arbitrator’s determination shall be made within 45 days after submission of the matters in dispute and shall be final and binding on all Parties, without right of appeal. In determining the proper amount of the Closing Adjustment and the Purchase Price, the Accounting Arbitrator shall be bound by the terms of this Section 1.3 and may not increase the Purchase Price above the Purchase Price proposed by Seller in the Seller Closing Statement nor decrease the Purchase Price below the Purchase Price proposed by Buyer in the Buyer Closing Statement, as applicable. The Accounting Arbitrator shall act as an expert for the limited purpose of determining the specific disputed aspects of the Closing Adjustment submitted by either Party (which shall be consistent with the contents of the Seller Closing Statement or Buyer Closing Statement except as otherwise agreed to in writing by the Parties) and may not award damages, interest (except as expressly provided for in this Section 1.3(d)) or penalties to any Party with respect to any matter. The Parties shall each bear its own legal fees and other costs of presenting its case, including one half of the costs and expenses of the Accounting Arbitrator, respectively. Within 10 days after the earlier of (i) the expiration of Buyer’s 45 day review period without delivery of the Buyer Closing Statement or (ii) the date on which the Parties or the Accounting Arbitrator finally

determine the Purchase Price, (x) Buyer shall pay to Seller the amount by which the portion of the Purchase Price to which Seller is entitled exceeds the Estimated Purchase Price, or (y) Seller shall pay to Buyer the amount by which the Estimated Purchase Price exceeds the Purchase Price to which Seller is entitled, as applicable. Any post-Closing payment pursuant to this Section 1.3(d) shall bear interest from the Closing Date to the date of payment at rate per annum equal to the prime rate of interest as reported in The Money Rates table of The Wall Street Journal from time to time in effect, plus four percent. Buyer and Seller agree that any payments made pursuant to this Section 1.3 shall be allocated in a manner consistent with the allocation referred to in Section 1.6.

(e) All payments made or to be made under this Agreement to Seller shall be made by electronic transfer of immediately available funds to a bank and account specified by Seller in writing to Buyer, for the credit of Seller. All payments made or to be made hereunder to Buyer shall be by electronic transfer or immediately available funds to a bank and account specified by Buyer in writing to Seller, for the credit of Buyer.

(a) a certificate of the secretary of Seller respecting, and to which is attached, (i) the certificate of formation of Seller; (ii) resolutions of Seller authorizing the execution of this Agreement and the Other Transaction Documents and the consummation of the transaction contemplated hereby and thereby (to the extent required under Seller’s organizational documents); (iii) resolutions of each Affiliate of Seller who is a party to any Other Transaction Document authorizing the execution of such Other Transaction Document(s) to which it is a party and the consummation of the transactions contemplated thereby (to the extent required under the organization documents of such Affiliate) and (iv) a certificate respecting the incumbency and true signatures of the officers who execute this Agreement and any other agreement, certificate or document related hereto or executed in connection herewith on behalf of Seller or any of its Affiliates;

Buyer shall, within the later of (a) 60 days following the Closing, or (b) 15 days after the final Purchase Price is determined under Section 1.3, prepare and deliver to Seller for its review and approval (i) an allocation of the Purchase Price among the Assets consistent with the principles of Section 1060 of the Code and the Treasury regulations promulgated thereunder (the “Allocation”) and (ii) a draft Internal Revenue Service Form 8594 (Asset Allocation Statement) consistent therewith. Any disputes with respect to the Allocation that cannot be resolved by the Parties shall be referred to the Accounting Arbitrator for resolution with such resolution to be made within 30 days of such referral. All expenses of the Accounting Arbitrator shall be shared by the Seller and Buyer equally. The Parties agree (A) to file Internal Revenue Service Form 8594 (Asset Allocation Statement) as well as any similar state or local form consistently with the Allocation, in each case as agreed, and (B) that neither Seller nor Buyer or any of their respective Affiliates or direct or indirect owners shall take a position on any Tax Return, or before any Governmental Authority in connection with the examination of a Tax Return or in any judicial proceeding, that is in any manner inconsistent with the terms of the Allocation, except as required by applicable Law.

Section 1.7. Nonassignable Assets.

(a) Nothing in this Agreement, nor the consummation of the transactions contemplated hereby, shall be construed as an attempt or agreement to assign or transfer any Asset (including any Assigned Contract) to Buyer or a Buyer Subsidiary, as applicable, which by its terms or by Law is nonassignable without a Consent (a “Nonassignable Asset”), unless and until such Consent shall have been obtained. Seller shall advise Buyer in writing at least five Business Days prior to the Closing (a) of any Material Contract with respect to which a Consent of the counterparty is required for assignment and for which such Consent has not been obtained and (b) if Seller has received notice (whether written or oral) that any such third Person will not agree to the assignment of any Material Contract to Buyer or a Buyer Subsidiary, as applicable, hereunder at the Closing. To the extent permitted by applicable Law and by the terms of the applicable Nonassignable Asset, such Nonassignable Asset shall be held, as of and from the Closing Date, by Seller for the benefit and burden of Buyer or a Buyer Subsidiary, as applicable, and the covenants and obligations thereunder shall be fully performed by Buyer or such Buyer Subsidiary, as applicable, on Seller’s behalf and all rights and Liabilities existing thereunder shall be for Buyer’s or such Buyer Subsidiary’s account, as applicable. For the avoidance of doubt, the designation of an Asset as a Nonassignable Asset does not render it an Excluded Asset.

(b) To the extent permitted by applicable Law and by the terms of the applicable Nonassignable Asset, Seller and Buyer shall take, or cause to be taken, such actions as the other party may reasonably request that are required to be taken or appropriate in order to provide Buyer or a Buyer Subsidiary, as applicable, with the benefits and burdens of the Nonassignable Assets. Seller shall promptly pay over to Buyer or such Buyer Subsidiary, as applicable, the net amount (after de minimis reasonable administrative expenses and an adjustment for Taxes consistent with Section 1.3 placing each party as nearly as possible in the same position as if the Nonassignable Asset had been transferred to Buyer or such Buyer Subsidiary, as applicable, on the Closing Date), of all payments received by it in respect of all Nonassignable Assets and Buyer shall indemnify Seller for all Losses attributable to Seller’s holding of all Nonassignable Assets

(c) The Parties shall continue after the Closing to use all commercially reasonable efforts to obtain the applicable Consents to assign any Nonassignable Asset that were not obtained prior to the Closing.

(d) The provisions of this Section 1.7 shall not apply in respect of the Real Property Consents, which shall be governed by Section 1.8.

Section 1.8. Real Property Consents.

(a) Seller shall identify, with respect to the Assets, all Real Property Consents and other provisions restricting assignment without Consent that would be applicable to the transactions contemplated hereby and the names and addresses of the parties holding such Real Property Consents. Seller will request, from the parties so identified (and in accordance with the documents creating such rights), and will use commercially reasonable efforts to obtain, execution of all Real Property Consents. During such period in which the applicable Asset is not capable of being assigned to Buyer or a Buyer Subsidiary, as applicable, due to the failure to obtain an execution of a Real Property Consent, the Parties mutually agree, as is reasonably practicable, to cooperate to obtain an execution of such Real Property Consent or to make or cause to be made such arrangements as may be reasonably necessary or requested by Buyer to enable Buyer or such Buyer Subsidiary, as applicable, to receive all the economic benefits or same or similar rights with respect to such Asset.

(b) Real Property Interests with respect to which a Real Property Consent has not been obtained on or before the day that is three Business Days prior to Closing shall be deemed to be excluded from the Assets conveyed to Buyer or a Buyer Subsidiary, as applicable, at Closing, but the Unadjusted Purchase Price shall not be reduced.

(c) With respect to any Real Property Interest upon which any pipeline comprising part of the Processing Facilities or the Ranger NGL Pipeline is located, if, under the terms of such Real Property Interest, a Real Property Consent is required prior to the assignment of such Real Property Interest to Buyer or a Buyer Subsidiary, as applicable, and such Real Property Consent has not been obtained prior to the Closing, this Agreement shall not constitute an agreement to convey at the Closing such Real Property Interest or the portions of such Processing Facilities or Ranger NGL Pipeline that are located upon such Real Property Interest. In such case, the Parties may agree that (i) with respect to the portions of such Processing Facilities or Ranger NGL Pipeline not conveyed at the Closing (the “EQT Processing Facilities”), the Parties shall enter into an agreement (the “EQT Processing Facilities Agreement”), the form and substance of which shall be mutually agreed by the Parties, that provides Buyer or such Buyer Subsidiary, as applicable, to the commercially reasonable extent possible, with the rights, benefits and burdens with respect to the EQT Processing Facilities that Buyer or such Buyer Subsidiary, as applicable, would have received had such EQT Processing Facilities been conveyed to Buyer or such Buyer Subsidiary, as applicable, at the Closing and (ii) the other portions of such Processing Facilities or Ranger NGL Pipeline and the related Real Property Interests shall be conveyed to Buyer or such Buyer Subsidiary, as applicable, at the Closing. With respect to any portion of the EQT Processing Facilities and related Real Property Interests to

which an EQT Processing Facilities Agreement applies, when the applicable Real Property Consents are obtained, Seller shall convey the applicable portions of the EQT Processing Facilities and assign, pursuant to a special warranty deed, such related Real Property Interests to Buyer or such Buyer Subsidiary, as applicable, within 10 days following receipt of such Real Property Consent, and the EQT Processing Facilities Agreement with respect to such portions of the EQT Processing Facilities shall terminate.

Buyer shall promptly pay to Seller the portion of such Tax for which Buyer is responsible pursuant to Section 5.2 within five days of receipt of notice therefor.

Section 5.2. Responsibility for Taxes. Seller shall be responsible for and entitled to all refunds of, and shall indemnify Buyer Indemnitees from and against, all Taxes with respect to the Assets for any Pre-Closing Period and for that portion of any Straddle Period that ends on the Closing Date. Buyer shall be responsible for the remaining Straddle Period Taxes that begins on the day after the Closing and ends on the last day of the Straddle Period. For this purpose, Straddle Period Taxes shall be (a) allocated on an interim closing of the books method for income and franchise Taxes, and (b) prorated on a daily basis to the Closing date and thereafter for all other Taxes. Notwithstanding anything to the contrary herein, any ad valorem or property Taxes paid or payable with respect to the Assets shall be allocated to the Tax period applicable to the ownership of the Assets regardless of when such Taxes are assessed.

Section 5.3. Post-Closing Assistance. Seller and Buyer will each provide the other such reasonable assistance, at the sole cost and expense of the requesting party, as may reasonably be requested in connection with the preparation of any Tax Return with respect to the Assets, or any audit or other examination by any Tax Authority or any judicial or administrative proceedings relating to Taxes with respect to the Assets, and each will retain and provide the requesting Party with any records or information that may be reasonably relevant to such return, audit or examination, proceedings or determination.

Section 5.4. Conduct of Business.

(a) From and after the applicable Closing Date, each of Buyer and Seller (the “Tax Indemnified Person”), shall notify the chief tax officer (and the notice party as set forth in Section 10.4 of this Agreement) of the other Party (the “Tax Indemnifying Person”), in writing within 15 days of receipt by the Tax Indemnified Person of written notice of any pending or threatened audits, adjustments, claims, examinations, assessments or other proceedings (a “Tax Audit”) which may affect the liability for Taxes of such other Party. If the Tax Indemnified Person fails to give such timely notice to the other Party, it shall not

be entitled to indemnification for any Taxes arising in connection with such Tax Audit if such failure to give notice materially adversely affects the other Party’s right to participate or meaningfully defend in the Tax Audit.

(b) If a Tax Audit relates to Taxes for which only Seller would be liable to indemnify Buyer under this Agreement, Seller shall have the option, at its expense, to control the defense and settlement of such Tax Audit. If Seller does not elect to control the defense and settlement of such Tax Audit by giving written notice of to Buyer within 15 days of the receipt of the first notice of such audit (and failure to give such timely notice shall constitute a waiver of seller’s right to elect not to control and defend the audit), Buyer may, at Buyer’s expense, control the defense and settlement of such Tax Audit, provided that Seller shall pay any Tax for which it is otherwise liable under Section 5.2. If such Tax Audit relates solely to Taxes for which only Buyer would be liable under this Agreement, Buyer shall, at its expense, control the defense and settlement of such Tax Audit to the extent that such Tax Audit relates to Taxes for which Buyer is liable to indemnify Seller under Section 5.2.

(c) If a Tax Audit relates to Taxes for which both Seller and Buyer could be liable under this Agreement, to the extent practicable, the items of income, gain, loss, deduction and credit or other item required to be reported on or otherwise reported on the applicable Tax Return (“Tax Items”) with respect to such Tax Audit will be distinguished and each Party will have the option to control the defense and settlement of those Taxes for which it is so liable. If such Tax Audit relates to a Straddle Period and any Tax Item cannot be identified as being a liability of only one Party or cannot be separated from a Tax Item for which the other Party is liable, Seller, at its expense, shall have the option to control the defense and settlement of the Tax Audit, provided that such Party defends the items as reported on the relevant Tax Return and provided further that no such matter shall be settled without the written consent of Buyer, not to be unreasonably withheld.

(d) Any Party whose liability for Taxes may be affected by a Tax Audit shall be entitled to participate at its expense in such defense and to employ counsel of its choice at its expense and shall have the right to consent to any settlement of such Tax Audit (not to be unreasonably withheld) to the extent that such settlement would have an adverse effect with respect to a period for which that Party is liable for Taxes, under this Agreement or otherwise.

Section 5.5. Pre- and Post-Closing Actions. Except to the extent required by applicable Laws, Seller shall not and shall not permit its affiliates to take any action (including the amendment of any Tax Return) on or before the Closing Date which could reasonably be expected to materially increase Buyer’s liability for Taxes (including any liability of Buyer to indemnify Seller for Taxes under this Agreement). Except to the extent required by applicable

Laws, Buyer shall not and shall not permit its affiliates to take any action (including the amendment of any Tax Return) on or after the Closing Date which could reasonably be expected to materially increase Seller’s liability for Taxes (including any liability of Seller to indemnify Buyer for Taxes under this Agreement).

Section 5.6. Refunds of Certain Taxes Received by Buyer. Buyer agrees to pay to Sellers any refund received (whether by payment, credit, offset or otherwise, and together with any interest thereon) after the Closing Date by Buyer or its affiliates that is entitled to be paid to Seller pursuant to Section 5.2. Buyer shall cooperate with Seller and Seller’s affiliates at Seller’s sole expense in order to take all necessary steps to claim any such refund.

Buyer shall have no affirmative duty to identify any refunds that might be due and payable to Seller under this Section 5.6.

Section 5.7. Like-Kind Tax Exchange. The Parties hereby agree that any Party, at its sole expense, may elect a like-kind exchange under Section 1031 of the Code with respect to the transactions contemplated by this Agreement. Seller, at its expense, shall have the right at any time prior to the Closing to assign all or a portion of its rights under this Agreement to a “qualified intermediary” (as that term is defined in Treasury Regulations Section 1.1031(k)-1(g)(4)(iii)) or an “exchange accommodation titleholder” (as that term is defined in Revenue Procedure 2000-37, 2000-2 C.B. 308) in order to effectuate the transactions contemplated hereby at such Closing in a manner that will qualify, either in whole or in part, as a like-kind exchange under Section 1031 of the Code.

The Parties agree to cooperate to the extent reasonably requested by the other Parties in order to effectuate the transactions contemplated hereby as a like-kind exchange under Section 1031 of the Code. The Parties acknowledge and agree that any assignment of rights under this Agreement to a qualified intermediary or an exchange accommodation titleholder shall not release any Party from any of its liabilities and obligations to the other Party under this Agreement, and that neither Party represents to the other Party that any particular Tax treatment will be given to any Party as a result thereof. In no event will any Party be liable to the other for any failure of any transaction to qualify for like-kind treatment under Section 1031 of the Code.

Section 5.8. Transfer Taxes. Any sales, use, recording or other transfer taxes (“Transfer Taxes”) imposed on the purchase and sale of the Assets pursuant to this Agreement (including any interest, penalties, or additions to tax with respect thereto) shall be paid 50% by Seller and 50% by Buyer. The Parties shall reasonably cooperate in good faith to minimize, to the extent permissible under applicable Law, the amount of any Transfer Taxes described in this Section 5.8.

Notwithstanding the foregoing, Buyer acknowledges that in the case of each Transition IT System licensed to Seller or its Affiliates, the consent of the licensor of such Transition IT System may be required to provide Buyer any use or access to such Transition IT System, and Seller’s obligations under this Agreement are limited to providing assistance reasonably requested by Buyer to obtain such consent in consideration of the payments described in clause (a) of this Section 6.12.

Buyer shall pay Seller an amount equal to all reasonable out-of-pocket or third-party costs incurred by Seller under this Section 6.12(c). Seller makes no representations or warranties regarding Buyer’s ability to obtain the Buyer Master Agreements, and Seller shall have no liability by reason of it’s efforts to hold the Retained Master Agreements for the benefit and burden of Buyer pursuant to this Section 6.12(c).

Both Parties will participate and consult with the Engineering Firm for the purpose of ensuring that, to the extent possible, the ▇▇▇▇▇▇▇ Site Development Plans, as well as any anticipated future expansions of the Processing Facilities and the Big ▇▇▇▇▇ Pipeline (e.g., by adding an additional residue gas line), utilize available space on the site of the Processing Facilities to accommodate ▇▇▇▇▇▇▇ Plant 3, the Big ▇▇▇▇▇ Compression Expansion, and such anticipated future expansions of the Processing Facilities and the Big ▇▇▇▇▇ Pipeline. The Parties shall use commercially reasonable efforts to cause the Engineering Firm to complete the ▇▇▇▇▇▇▇ Site Development Plans within 120 days of the date hereof. The Parties will each bear 50% of the cost of the Engineering Firm. After the Closing, the Parties agree to amend the Conveyance to specify the location and extent of Seller’s retained easement for purposes of accessing, operating and expanding the Big ▇▇▇▇▇ Pipeline compression included in the Excluded Assets.

Section 9.2. Seller’s Agreement to Indemnify.

(a) Subject to the terms and conditions set forth herein, from and after the Closing, Seller shall indemnify and hold harmless Buyer and its directors, officers, employees, Affiliates, controlling Persons, agents and representatives and their respective successors and assigns (collectively, the “Buyer Indemnitees”) from and against all liability, demands, claims, actions or causes of action, penalties, fines, assessments, deficiencies, settlements, judgments, losses, damages, costs and expenses (including reasonable fees and expenses for attorneys, accountants, engineers and investigators) (collectively, “Buyer Damages”) asserted against or incurred by any Buyer Indemnitee as a result of or arising out of any of the following:

(i) a breach of any representation or warranty of Seller contained in ARTICLE II other than a Seller Fundamental Representation or the Seller Tax Representation;

The maximum amount that Seller shall be required to pay in the aggregate pursuant to Section 9.2(a)(i) and Section 9.2(a)(v) in respect of all Buyer Damages by all Buyer Indemnitees is the Indemnification Ceiling less the Indemnification Deductible, after which point Seller will not have an obligation to indemnify Buyer from and against further such Buyer Damage.

(ii) Seller’s obligation to indemnify Buyer under Section 9.2(a)(ii) through Section 9.2(a)(iv) shall not be subject to any of the limitations set forth in Section 9.2(b)(i); provided that the maximum amount that Seller shall be required to pay in the aggregate pursuant to Section 9.2(a) in respect of all Buyer Damages to all Buyer Indemnitees shall be the Unadjusted Purchase Price.

(iii) The amount of any Buyer Damages shall be reduced by (A) any amount directly received by a Buyer Indemnitee with respect thereto under any insurance coverage or for any other party alleged to be responsible therefor (except such amount shall be adjusted by any increase in insurance premiums payable by Buyer as a result of such insurance claim), (B) the amount of any Tax benefit actually realized by Buyer

Indemnitee in the form of an actual refund or credit of current Taxes payable in the year the Loss is claimed by Buyer with respect the applicable indemnification against Seller and (C) any indemnity, contribution or other similar payment actually received by Buyer or any Buyer Indemnitee from any third Person with respect to such Buyer Damages. If a Buyer Indemnitee directly or indirectly receives an amount under insurance coverage or from such other party with respect to Buyer Damages at any time subsequent to any indemnification provided by Seller pursuant to this Section 9.2, then such Buyer Indemnitee shall promptly reimburse Seller for any payment made or expense incurred by Seller in connection with providing such indemnification up to such amount received by Buyer Indemnitee. Each Buyer Indemnitee shall take all reasonable steps to mitigate damages in respect of any claim for which such Buyer Indemnitee is seeking indemnification and shall use commercially reasonable efforts to avoid any costs or expenses associated with such claim and, if such costs and expenses cannot be avoided, to minimize the amount thereof.

(iv) Seller shall be obligated to indemnify Buyer Indemnitees only for those claims giving rise to Buyer Damages as to which Buyer Indemnitees have given Seller written notice thereof, and with respect to any claim pursuant to Section 9.2(a)(i), such notice must be given prior to the end of the Survival Period with respect to such claim. Any written notice delivered by a Buyer Indemnitee to Seller with respect to Buyer Damages shall set forth with as much specificity as is reasonably practicable the basis of the claim for Buyer Damages and, to the extent reasonably practicable, a reasonable estimate of the amount thereof.

(c) Seller’s obligation to indemnify the Buyer Indemnities pursuant to Section 9.2(a)(v) is subject to the following limitations:

(i) Seller’s obligation to indemnify the Buyer Indemnitees pursuant to Section 9.2(a)(v) shall survive the Closing until **

Any written notice delivered by a Buyer Indemnitee to Seller with respect to Buyer Damages under Section 9.2(a)(v) shall set forth with as much specificity as is reasonably practicable the basis of the claim for Buyer Damages, a reasonable estimate of the amount thereof, and shall include copies of any correspondence with any Governmental Agency regarding the asserted Buyer Damages.

(iii) The amount that Seller shall be required to pay pursuant to Section 9.2(a)(v) shall be ** until the aggregate amount of such Buyer Damages (together with any Buyer Damages described in Section 9.2(a)(i)) equals the Indemnification Deductible, and ** until the aggregate amount of such Buyer Damages (together with any Buyer Damages described in Section 9.2(a)(i)) equals the Indemnification Ceiling, after which Seller shall have no responsibility for any additional Buyer Damages under Section 9.2(a)(i) or Section 9.2(a)(v).

(iv) Buyer claims for indemnification under Section 9.2(a)(v) shall be ** to the extent applicable ** and to the extent Buyer has legal capacity to do so, **

(v) Buyer shall take all reasonable actions to avoid and minimize any claim for indemnification under Section 9.2(a)(v), **

(vi) Notwithstanding any other provision in this Agreement, Section 9.2(a)(v) shall constitute Buyer’s sole and exclusive remedy for any Buyer Damages related to ▇▇▇▇▇▇▇ Plant Environmental Matters.

(d) The limitations on indemnification set forth in Section 9.2(b) shall not apply to any claim or Buyer Damages for fraud or willful misconduct on the part of Seller.

(e) In determining the amount of any claim or Buyer Damages, all materiality and “Seller Material Adverse Effect” qualifiers contained in any representations and warranties or covenants shall be ignored.

THIS INDEMNIFICATION IS EXPRESSLY INTENDED TO APPLY NOTWITHSTANDING ANY NEGLIGENCE (WHETHER SOLE, CONCURRENT, ACTIVE OR PASSIVE) OR OTHER FAULT OR STRICT LIABILITY ON THE PART OF BUYER INDEMNITEES (BUT NOT TO THE EXTENT OF SUCH BUYER INDEMNITEE’S WILLFUL MISCONDUCT OR GROSS NEGLIGENCE).

Section 9.3. Buyer’s Agreement to Indemnify.

(a) Subject to the terms and conditions set forth herein, from and after the Closing, Buyer shall indemnify and hold harmless Seller and its directors, officers, employees, Affiliates, controlling Persons, agents and representatives and their respective successors and assigns (collectively, the “Seller Indemnitees”) from and against all liability, demands, claims, actions or causes of action, penalties, fines, assessments, deficiencies, settlements, judgments, losses, damages, costs and expenses (including reasonable fees and expenses for attorneys, accountants, engineers and investigators) (collectively, “Seller

Damages”) asserted against or incurred by any of Seller Indemnitees as a result of or arising out of any of the following:

(i) a breach of any representation or warranty contained in ARTICLE IV other than any Buyer Fundamental Representation;

(ii) a breach of any Buyer Fundamental Representation;

(iii) a breach of any covenant of Buyer contained in this Agreement; and

(iv) the Assumed Liabilities.

(b) Buyer’s obligation to indemnify Seller Indemnitees pursuant to Section 9.3(a) is subject to the following limitations:

The maximum amount that Buyer shall be required to pay in the aggregate pursuant to Section 9.3(a)(i) in respect of all Seller Damages by all Seller Indemnitees is the Indemnification Ceiling less the Indemnification Deductible, after which point Buyer will not have an obligation to indemnify Seller from and against further such Seller Damage.

(ii) Buyer’s obligation to indemnify Seller under Section 9.3(a)(ii) through Section 9.3(a)(iv) shall not be subject to any of the limitations set forth in Section 9.3(b)(i); provided that the maximum amount that Buyer shall be required to pay in the aggregate pursuant to Section 9.3(a) in respect of all Seller Damages to all Seller Indemnitees is the Unadjusted Purchase Price.

(iii) The amount of any Seller Damages shall be reduced by (A) any amount directly received by a Seller Indemnitee with respect thereto under any insurance coverage or for any other party alleged to be responsible therefor (except such amount shall be adjusted by any increase in insurance premiums payable by Seller as a result of such insurance claim), (B) the amount of any Tax benefit actually realized by Seller Indemnitee in the form of an actual refund or credit of current

Taxes payable in the year the Loss is claimed by Seller with respect the applicable indemnification against Buyer and (C) any indemnity, contribution or other similar payment actually received by Seller or any Seller Indemnitee from any third Person with respect to such Seller Damages. If Seller Indemnitees directly or indirectly receive any amounts under insurance coverage or from such other party with respect to Seller Damages at any time subsequent to any indemnification provided by Buyer pursuant to this Section 9.3, then Seller Indemnitees shall promptly reimburse Buyer, as the case may be, for any payment made or expense incurred by Buyer in connection with providing such indemnification up to such amount received by Seller Indemnitees. Each Seller Indemnitee shall take all reasonable steps to mitigate damages in respect of any claim for which such Seller Indemnitee is seeking indemnification and shall use commercially reasonable efforts to avoid any costs or expenses associated with such claim and, if such costs and expenses cannot be avoided, to minimize the amount thereof.

(iv) Buyer shall be obligated to indemnify Seller Indemnitees only for those claims giving rise to Seller Damages as to which Seller Indemnitees have given Buyer written notice thereof, and with respect to a claim pursuant to Section 9.3(a)(i), such notice must be given prior to the end of the Survival Period. Any written notice delivered by Seller Indemnitees to Buyer with respect to Seller Damages shall set forth with as much specificity as is reasonably practicable the basis of the claim for Seller Damages and, to the extent reasonably practicable, a reasonable estimate of the amount thereof.

(c) The limitations on indemnification set forth in Section 9.3(b) shall not apply to any claim or Seller Damages for fraud or willful misconduct on the part of Buyer.

(d) In determining the amount of any claim or Seller Damages, all materiality and “Buyer Material Adverse Effect” qualifiers contained in any representations and warranties or covenants shall be ignored.

THIS INDEMNIFICATION IS EXPRESSLY INTENDED TO APPLY NOTWITHSTANDING ANY NEGLIGENCE (WHETHER SOLE, CONCURRENT, ACTIVE OR PASSIVE) OR OTHER FAULT OR STRICT LIABILITY ON THE PART OF SELLER INDEMNITEES (BUT NOT TO THE EXTENT OF SUCH SELLER INDEMNITEE’S WILLFUL MISCONDUCT OR GROSS NEGLIGENCE).

Section 9.4. Third Party Indemnification. The obligations of Seller to indemnify Buyer Indemnitees under Section 9.2 with respect to Buyer Damages and the

obligations of Buyer to indemnify Seller Indemnitees under Section 9.3 with respect to Seller Damages, in either case resulting from the assertion of liability by third parties (each, as the case may be, a “Claim”), will be subject to the following additional terms and conditions. This Section 9.4 shall not apply to any claims or proceedings with respect to Taxes, which shall be governed by Section 5.4.

(a) Any Party against whom any Claim is asserted (the “Indemnified Party”) will give the indemnifying party (the “Indemnifying Party”) written notice of any such Claim promptly after learning of such Claim, and the Indemnifying Party may at its option and its sole expense undertake the defense thereof using reputable counsel and representatives of its own choosing who are reasonably satisfactory to the Indemnified Party; provided that the Indemnified Party shall be entitled to conduct and control the defense thereof (at their election and sole expense) if such Claim, based on the remedy sought, would reasonably be expected to subject any party to criminal liability of, or injunctive or other equitable relief against, the Indemnified Party (except as set forth in Section 6.10). All Claims are subject to the remaining obligations set forth in this Section 9.4(a) and Section 9.4(b). The Indemnified Party may participate, through counsel chosen by it and at its own expense, in the defense of any Claim as to which the Indemnifying Party has elected to conduct and control the defense, compromise or settlement thereof; provided that if counsel to the Indemnifying Party is ethically prohibited from representing the Indemnified Party due to the existence or development of a conflict between the interests of the Indemnifying Party and the Indemnified Party, then the Indemnifying Party shall also pay the reasonable fees and expenses of one separate counsel (reasonably acceptable to the Indemnifying Party) of the Indemnified Party in connection with such Claim during such time as such a conflict exists. In the event, however, that the Indemnifying Party declines or does not elect to conduct and control the defense, compromise or settlement of any Claim or to employ reputable counsel reasonably satisfactory to the Indemnified Party, in either case within such 30 day period, then the Indemnifying Party shall pay the reasonable fees and expenses of counsel for the Indemnified Party as incurred to the extent the Indemnifying Party is obligated to indemnify the Indemnified Party for such fees and expenses pursuant to this Section 9.4(a), as applicable; provided, however, that the Indemnifying Party shall not be required to pay the fees and disbursements of more than one firm for all Indemnified Parties in any Claim. The Indemnifying Party or the Indemnified Party (as the case may be) shall at all times use commercially reasonable efforts to keep the Indemnifying Party or Indemnified Party (as the case may be) reasonably apprised of the status of the defense of any matter the defense of which it is maintaining and to cooperate in good faith with each other with respect to the defense of any such matter and shall furnish such records and other information as may be reasonably requested by the Indemnifying Party or Indemnified Party (as the case may be) in connection therewith. Failure to give prompt notice of a

Claim hereunder shall not affect the Indemnifying Party’s obligations under this ARTICLE IX, except to the extent the Indemnifying Party is materially prejudiced by such failure to give prompt notice.

(b) Neither the Indemnifying Party nor the Indemnified Party, as the case may be, shall pay, compromise, settle or consent to the entry of any judgment with respect to which indemnification is being sought herein without the prior written consent of the other Party, which consent may not be unreasonably withheld, delayed or conditioned; provided, however, that the Indemnified Party’s/Indemnifying Party’s (as applicable) consent will not be required if such settlement, compromise or consent includes an unconditional release of the Indemnified Party/Indemnified Party (as applicable) from all liability arising out of such claim and such settlement, compromise or consent does not contain any equitable order, judgment or term that may adversely affect the business of the Indemnified Party/Indemnifying Party (as applicable) (other than as the result of money damages covered by the indemnity). If the Indemnifying Party is entitled to conduct and control the defense of any particular claim pursuant to this Section 9.4, but elects not to do so, then the Indemnifying Party shall not unreasonably withhold its consent to any settlement or compromise with respect to such claim.

Section 9.5. Insurance. The Indemnifying Party shall be subrogated to the rights of the Indemnified Party in respect of any insurance relating to Buyer Damages or Seller Damages, as the case may be, to the extent of any indemnification payments made hereunder, and the Indemnified Party shall provide all reasonably requested assistance to the Indemnifying Party in respect of such subrogation.

Section 9.6. No Duplication. Any liability for indemnification hereunder shall be determined without duplication of recovery by reason of the state of facts giving rise to such liability constituting a breach of more than one representation, warranty, covenant or agreement herein.

Section 9.7. Amount of Losses. The determination of the dollar amount of any Buyer Damages or Seller Damages, as the case may be, shall be based solely on the actual dollar value thereof, on a dollar-for-dollar basis, and shall not take into account any multiplier valuations, including any multiple based on earnings or other financial indicia.

Section 9.8. Remedies Exclusive. Indemnification under this ARTICLE IX will be the exclusive remedy of any Indemnified Party for any breach of a representation or warranty in this Agreement and, in furtherance of the foregoing, each of the Parties, on behalf of itself and its Affiliates, hereby waives and releases the other Parties hereto (and such other Parties’ Affiliates) from, to the fullest extent permitted under any applicable Law, any and all rights, claims and causes of action it or its Affiliates may have against the other Parties hereto except as provided herein and provided, further, that nothing in this ARTICLE IX shall limit in any way

either Party’s remedies in respect of fraud or willful misconduct by the other Party in connection with the transactions contemplated hereby.

Section 9.9. Casualty and Condemnation. If, after the date of this Agreement but prior to the Closing Date, any portion of the Assets is destroyed or damaged by fire or other casualty or is expropriated or taken in condemnation or under right of eminent domain, Buyer shall, nevertheless be required to comply with the covenants in ARTICLE I and attend the Closing. In the event that the amount of the costs and expenses associated with repairing or restoring all Assets affected by such casualty or condemnation exceeds **, Seller must elect by written notice to Buyer prior to Closing either (i) to cause the Assets affected by any casualty or condemnation to be repaired, restored or replaced, at Sellers’ sole cost, as promptly as reasonably practicable (which work may extend after the Closing Date) or (ii) to indemnify Buyer through a document reasonably acceptable to the Parties against any costs or expenses that Buyer reasonably incurs to repair, restore or replace the Assets subject to any casualty. In the case of (i) and (ii) above, Seller shall retain all rights to insurance and other claims against third Persons with respect to the casualty or taking except to the extent the Parties otherwise agree in writing. Notwithstanding the foregoing, in the event that either (x) the above mentioned costs and expenses exceed ** or (y) the loss or taking of the affected Assets would substantially prevent the operation of the Processing Facilities or the operation or construction of the Ranger NGL Pipeline in the ordinary course of business consistent with past practices, then either Party will have the right to terminate this Agreement prior to Closing if Seller elects not to proceed under (i) or (ii) above.

Section 9.10. No Special Damages. IN NO EVENT SHALL ANY PARTY BE LIABLE UNDER THIS ARTICLE IX OR OTHERWISE IN RESPECT OF THIS AGREEMENT FOR EXEMPLARY, SPECIAL, PUNITIVE, INDIRECT, REMOTE, SPECULATIVE OR CONSEQUENTIAL DAMAGE; PROVIDED, HOWEVER, IF ANY OF THE SELLER INDEMNITEES OR BUYER INDEMNITEES IS HELD LIABLE TO A THIRD PERSON FOR ANY SUCH DAMAGES AND THE INDEMNITOR IS OBLIGATED TO INDEMNIFY SUCH SELLER INDEMNITEE OR BUYER INDEMNITEE FOR THE MATTER THAT GAVE RISE TO SUCH DAMAGES, THE INDEMNITOR SHALL BE LIABLE, AND OBLIGATED TO REIMBURSE SUCH INDEMNITEES, FOR SUCH DAMAGES.

Section 9.11. Conspicuous Legends; Nature of Indemnification. THE PARTIES AGREE THAT THE BOLD OR CAPITALIZED LETTERS IN THIS AGREEMENT CONSTITUTE CONSPICUOUS LEGENDS. IT IS EXPRESSLY ACKNOWLEDGED THAT THE INDEMNIFICATION PROVIDED IN THIS ARTICLE IX COULD INVOLVE INDEMNIFICATION FOR NEGLIGENCE OR UNDER THEORIES OF STRICT LIABILITY.
