Dear _________:
 
I am pleased to inform you that on [date of grant] the Compensation Committee (“Committee”) of the Board of Directors of National Fuel Gas Company (the “Company”) granted to you (the “Grantee” or “you”) ____ Performance Shares under the National Fuel Gas Company 2010 Equity Compensation Plan (the “Plan”), subject to a  Performance Goal related to total shareholder return, as set forth in this Award Notice.  Performance Shares are an award, pursuant to Section 9 of the Plan, constituting units denominated in Common Stock, the number of which such units may be adjusted over a Performance Cycle based upon the extent to which Performance Goals have been satisfied. 
The Performance Shares covered by this letter agreement (“Award Notice”) may be referred to in this Award Notice as “Your TSR Performance Shares.”  The number of Performance Shares set forth above is referred to in this Award Notice as the “Target Opportunity.”  The Plan and the Committee’s Administrative Rules (“Rules”) govern the operation of the Plan, as well as the terms and conditions of Your TSR Performance Shares, and are incorporated herein by reference.  Capitalized terms not otherwise defined herein shall have the meanings set forth for such terms in the Plan or the Rules.
1.    Performance Cycle and Performance Goal
The vesting of Your TSR Performance Shares is subject to a  Performance Goal as set forth in this Award Notice.  The Performance Cycle for Your TSR Performance Shares is [start date] through [end date].  Except as otherwise specified in the Plan or determined by the Committee, and to the extent the Performance Goal has been achieved, Your TSR Performance Shares shall vest on such date as the Committee determines the extent to which the Performance Goal has been achieved.  Such determination date shall be not later than [date].
The Performance Goal upon which any vesting and payment of Your TSR Performance Shares is conditioned shall be the Three-Year Total Shareholder Return (as defined below) of the 

Page 2

Company over the Performance Cycle relative to the Three-Year Total Shareholder Return of other companies in the Report Group (as defined below) for the Performance Cycle.  Three-Year Total Shareholder Return for the Company or any member of the Report Group shall be based on the data reported for that company (with the starting and ending stock prices over the Performance Cycle calculated as the average closing stock price for the prior calendar month and with dividends reinvested in that company’s securities at each ex-dividend date) in the Bloomberg online database (or, if the Bloomberg database ceases to be available, such alternative publication or service as the Compensation Committee shall designate) for the following group of companies for which data is available for the entire Performance Cycle (the “Report Group”):    
AGL Resources Inc.
Atmos Energy Corporation
Cabot Oil & Gas Corporation
Energen Corporation
EQT Corporation
MDU Resources Group Inc.
National Fuel Gas Company
New Jersey Resources Corporation
Northwest Natural Gas Company
Questar Corporation
Range Resources Corporation
SM Energy Company
Southwest Gas Corporation
UGI Corporation
Ultra Petroleum Corporation
Whiting Petroleum Corporation
To the extent reasonably correctible, the Committee shall correct the reported data for a known error in the reporting of the results of the Company.
The term “Percentile Ranking” as used in this Award Notice in reference to Three-Year Total Shareholder Return means the percentage determined by dividing:
		
	(A)
	the remainder of the Company’s rank within the Report Group for the Performance Cycle (measured lowest to highest) based on its Three-Year Total Shareholder Return for the Performance Cycle, minus one (1),

by
		
	(B)
	the number of companies (excluding the Company) in the Report Group for that Performance Cycle.

For purposes of determining the Company’s rank within the Report Group, if the Company’s Three-Year Total Shareholder Return for a Performance Cycle equals that of another company in the Report Group, the Company shall be ranked ahead of such other company.
Your TSR Performance Shares shall vest and payment shall be made on Your TSR Performance Shares to the extent the Company achieves the Percentile Ranking detailed below, provided that Your TSR Performance Shares have not previously been forfeited in accordance with applicable terms and conditions. 
	
		
	Company’s
Percentile Ranking
	Percentage of
Target Opportunity Paid

	 
	 

	30th or below
	0%

	40th
	50%

	50th
	100%

	70th
	150%

	90th or above
	200%

Notwithstanding the foregoing, if the Company’s Three-Year Total Shareholder Return is negative (less than 0.0), the percentage of Target Opportunity paid shall be capped at 100%.  For performance between two established performance levels, the percentage of Target Opportunity paid will be determined by mathematical interpolation.    
Any and all of Your TSR Performance Shares representing the percentage of the Target Opportunity not required to be paid shall not vest, and shall be automatically forfeited on the date the Compensation Committee makes its determination as to the extent to which the Performance Goal has been achieved, but no later than [date], if not previously forfeited in accordance with the terms and conditions applicable to such Performance Shares.
2.    Settlement
At the expiration of the Performance Cycle, the Committee shall certify in writing the number of Performance Shares earned and vested on the basis of performance in relation to the Performance Goal.   The Committee shall determine whether earned Performance Shares are to be distributed in the form of cash, shares of Common Stock or in a combination thereof, with the value or number of shares payable to be determined based on the Fair Market Value of the Common Stock on the date of the Committee’s certification.   Any fractional share otherwise payable in settlement of Your TSR Performance Shares shall be paid in cash.  
3.    Restrictions on Transferability
Your TSR Performance Shares may not be sold, assigned, transferred or pledged during the Performance Cycle, except that the Committee may permit (on such terms and conditions as it shall establish) some or all of Your TSR Performance Shares to be transferred during the Performance Cycle to a Permitted Transferee in accordance with Section 14(a) of the Plan.
4.    Rights as a Shareholder
You shall not have any right, in respect of Your TSR Performance Shares, to vote on any matter submitted to the Company’s stockholders until such time, if any, as the shares of Common Stock attributable to Your TSR Performance Shares have been issued. Dividend Equivalents shall not be paid or payable on Your TSR Performance Shares before they become earned and vested.

5.    Termination of Employment
In the event your employment with the Company or its Subsidiaries terminates due to your death, Disability or Retirement, or due to the Company divestiture of one or more Subsidiaries or other business segments, divisions or operations in a transaction that does not otherwise qualify as a Change in Control, then the number of Your TSR Performance Shares that otherwise would have vested after the end of the Performance Cycle shall be pro-rated to reflect the time period from the commencement of the Performance Cycle through the date of the termination of your service to the Company or its Subsidiaries, as described in Sections 11(a)(i) and 11(c)(i), respectively, of the Plan, and any of Your TSR Performance Shares that do not vest shall automatically be forfeited.  In the event your employment with the Company or its Subsidiaries terminates for any other reason, the provisions of the Plan shall control.
6.    Change in Control
Subject to the terms of the Plan and the Rules, in the event of a Change in Control of the Company, each of Your TSR Performance Shares then outstanding shall be deemed earned at the target level of performance for such Award.  In addition, the Committee may direct that each of Your TSR Performance Shares be settled in cash with its value determined based on the value received by the shareholders in any transaction that constitutes a Change in Control.  The Plan also allows the Committee to reasonably determine in good faith, before a Change in Control, that this Award shall be honored or assumed, or new rights substituted therefore, by your employer or the parent or affiliate of your employer, provided that any such honored, assumed or substituted award must satisfy the requirements set forth in Section 12(b) of the Plan, including “substantially equivalent economic value.” 
7.    Adjustments in Common Stock
In the event of an Adjustment Event, including any stock dividend, stock split, merger, consolidation, reorganization, recapitalization or other similar event affecting the Common Stock, the Committee shall equitably adjust, in its discretion, the number of shares subject to this Award Notice.  To the extent the Committee deems equitable and appropriate and subject to any required action by shareholders of the Company or of any successor in interest to the Company or any direct or indirect parent corporation of the Company or any such successor, in any Adjustment Event that is a merger, consolidation, reorganization, liquidation, dissolution or similar transaction, Your TSR Performance Shares shall be deemed to pertain to the securities and other property, including cash, to which a holder of the number of shares of Common Stock covered by this Award Notice would have been entitled to receive in connection with such Adjustment Event.  Any Committee determination pursuant to this Section 7 shall be final, binding and conclusive.
8.    Authority of Committee 
The Committee has the authority to interpret the Plan and all Performance Shares granted thereunder, to establish rules and regulations relating to the Plan and to make all other determinations it believes necessary or advisable for the administration of the Plan.  The scope of 

Page 4

The Performance Share award under the Plan does not alter, amend or otherwise affect your employment status with the Company or its subsidiaries.  No contract or right of employment shall be implied by this Award Notice.
(b)    The Committee may at any time unilaterally amend any unpaid Performance Shares award, including Awards earned but not yet paid, to the extent it deems appropriate, provided, however, that subject to Section 5(d) of the Plan, any such amendment which is adverse to the Grantee shall require the Grantee’s consent unless the Committee determines that such amendment or modification is necessary or advisable to comply with applicable law as a result of changes in law or regulation or to avoid the imposition of an additional tax, interest or penalty under Section 409A of the Internal Revenue Code of 1986, as amended.
(c)    If Your TSR Performance Shares are assumed or new Performance Shares are substituted therefor in any corporate reorganization (including, but not limited to, any transaction of the type referred to in Section 424(a) of the Internal Revenue Code of 1986, as amended), employment by such assuming or substituting company or by a parent company or a subsidiary thereof shall be considered for all purposes of this Award Notice to be employment by the Company.
(d)    In consideration of the Grantee’s privilege to participate in the Plan, the Grantee agrees (i) not to disclose any trade secrets of, or other confidential/restricted information of the Company to any unauthorized party, (ii) not to make any unauthorized use of such trade secrets or confidential or restricted information during his or her employment with the Company or its Subsidiaries or after such employment is terminated, and (iii) not to solicit any then current employees of the Company or any other subsidiaries of the Company to join the Grantee at his or her new place of employment after his or her employment with the Company or its Subsidiaries is terminated.
(e)    This Award Notice, together with the Plan and the Rules, constitutes the entire agreement between the parties with respect to the subject matter hereof.  You hereby acknowledge that you have been provided with a copy of the Plan and the Rules, and understand the terms and conditions of these documents and of this Award Notice.
(f)    In the event of the invalidity of any part or provision of this Award Notice, such invalidity shall not affect the enforceability of any other part or provision hereof.

Page 5

taxes required by law to be withheld with respect to such payment or may require you to pay to it such tax prior to and as a condition of the making of such payment.  Subject to the Rules and any Committee established regulations or procedures, you may pay the amount of taxes the law requires to be withheld, in whole or in part, by requesting that the Company withhold from any payment of Common Stock due in settlement of Your TSR Performance Shares, or by delivering to the Company, shares of Common Stock having a Fair Market Value less than or equal to the amount of such required withholding taxes.
11.    Securities Law Requirements
The Company will not be required to issue shares in settlement of Your TSR Performance Shares unless and until (a) such shares have been duly listed upon each stock exchange on which the Company’s Common Stock is then registered and (b) a registration statement under the Securities Act of 1933 with respect to such shares is then effective.  The Board may require you to furnish to the Company, prior to the issuance of any shares of Common Stock in connection with the settlement of Your TSR Performance Shares, an agreement, in such form as the Board may from time to time deem appropriate, in which you represent that the shares you acquired upon such settlement are being acquired for investment and not with a view to the sale or distribution thereof.
12.    Performance Shares Subject to Plan and Rules
Your TSR Performance Shares shall be subject to all the terms and provisions of the Plan, the Rules and this Award Notice, and you shall abide by and be bound by such terms and provisions and all rules, regulations and determinations of the Board or the Committee now or hereafter made in its discretion in connection with the administration of the Plan.

[REDACTED]*. Except as expressly set forth herein, MarkWest or its Affiliates shall own all the appurtenances, additions, extensions, improvements, or expansions of or to the Facilities that are constructed by them, which additions shall
become a part of the Facilities and shall be subject to this Agreement. 
 4.3 At such time that Producer desires to connect a well or wells located within
the Dedication Area (each such well, a “New Well”) to the Facilities, Producer will furnish MarkWest with information regarding the location of such New Well, the anticipated in-service date for such New Well and all available test
results for such New Well. Except as expressly set forth herein, MarkWest shall install, own and operate extensions of the Gathering System as necessary to connect New Wells in accordance with the following provisions: 

a. If the New Well is within the Gathering Boundary, then MarkWest will use commercially reasonable efforts to connect such New Well as soon as
reasonably practicable. 

  
 Page 5 of 20 

 b. If the New Well is outside of the Gathering Boundary, then Producer may, at its option,
(x) request that MarkWest install and operate the necessary connection, pipelines and related facilities to connect such well to the Facilities; or (y) install, own and operate, or engage a third party to install, own and operate, the
necessary facilities to connect the well to the Facilities, and in either case to deliver the Gas from such well to MarkWest hereunder. If Producer requests that MarkWest install and operate the connection to the Facilities, and MarkWest determines
that the connection of such well will be economic under the terms of this Agreement, then MarkWest will use commercially reasonable efforts to connect such well as soon as reasonably practicable. If MarkWest determines that the connection of that
well will not be economic under the terms of this Agreement, MarkWest may either propose terms on which such connection would be economic or decline to provide such terms. If (i) Producer elects to proceed with the well connection independently
under Section 4.3.b.(y), or (ii) MarkWest declines to offer terms for the well connection pursuant to the preceding sentence or the Parties are unable to agree on the terms provided to Producer for the well connection pursuant to the
preceding sentence and Producer elects to proceed with the well connection independently, then Producer shall not be charged and shall have no obligation to pay any gathering or other transportation fees for Gas being transported through such
facilities installed, owned and operated by Producer or a third party but shall pay MarkWest a gathering and/or processing fee in accordance with the following provisions and the terms of this Agreement: 

i. If Producer elects to connect the well to the Gathering System, [REDACTED]*. For Producer’s Gas processed at the Processing
Plant from any well connected to the Gathering System pursuant to the terms of this Section 4.3.b.i., Producer shall pay MarkWest a processing fee of [REDACTED]* for the processing of Producer’s Gas from such well; and 

ii. If Producer elects to connect the well directly to the Processing Plant, then Producer shall pay MarkWest a processing fee of
[REDACTED]* for the processing of Producer’s Gas from such well but Producer shall have no obligation to pay any gathering or other transportation fees for such Gas being transported. 

iii. Notwithstanding anything in this Section 4.3 to the contrary, unless the Parties agree otherwise in writing, to the extent that
Producer elects to gather production from its recently acquired acreage in Butler County, Pennsylvania (the “Shell Acreage”), then: [REDACTED]*. 

The point of interconnection between the facilities installed, owned and operated by Producer and the Facilities shall be the Receipt Point for
Producer’s Gas from any well connected pursuant to this Section 4.3.b. Producer acknowledges and agrees that the nature of any gathering facilities installed, owned and operated by Producer or its designee pursuant to the terms of this
Section 4.3.b. (e.g. the diameter of gathering pipeline) and the manner in which Producer or its designee operates such facilities will affect, and may adversely impact, MarkWest’s ability to receive Producer’s Gas. 

4.4 MarkWest shall ensure that Producer’s Gas with Priority Capacity Rights that is delivered to the Processing Plant is given priority to the available
capacity of the Processing Plant in accordance with such Priority Capacity Rights. 
 4.5 It is understood and agreed that either Party hereto may, without
liability to the other Party, interrupt the operations of its facilities for the purpose of making necessary alterations, maintenance or repairs thereto or to comply with applicable regulatory requirements. MarkWest will exercise due diligence to
schedule routine repair and maintenance so as to minimize disruption of service hereunder, and except in situations reasonably perceived by MarkWest to be emergencies, shall use commercially reasonable efforts to provide at least fourteen
(14) days prior notice to Producer of such scheduled routine repair and maintenance. It is further understood and agreed that Producer shall, at all times, have the right to regulate the rate of production from any well as Producer determines,
in its sole discretion, necessary to optimize reservoir characteristics, maximize long-term production, or otherwise improve the economic performance of such well. 

ARTICLE 5: RECEIPT POINT AND CONDITIONS 
 5.1 Producer
shall deliver or shall cause to be delivered Gas to MarkWest at the Receipt Point(s). 
 5.2 Under normal operating conditions, Producer shall deliver or
shall cause to be delivered Gas hereunder to the Receipt Point(s) at a pressure not greater than 600 psig and not less than 100 psig, or such lower pressure as exists in the Gathering System at the Receipt Point(s). Notwithstanding anything to the
contrary herein, Producer shall have no obligation to compress Gas prior to delivery of such Gas at the Receipt Point(s). 
 ARTICLE 6: GAS PROCESSING

 6.1 Following the execution of this Agreement, and subject to the other provisions of this Agreement, MarkWest shall design, engineer, procure,
construct, install and operate the Processing Plant. 
 6.2 Producer will have Priority Capacity Rights at the Processing Plant as follows: 

a. Commencing on the Trigger Date and until [REDACTED]*, an aggregate of [REDACTED]* of processing capacity at the Processing
Plant; 
 b. Beginning [REDACTED]* and until [REDACTED]*, an aggregate of [REDACTED]* of processing capacity at the
Processing Plant; 

  
 Page 6 of 20 

 c. Beginning [REDACTED]* and until [REDACTED]*, an aggregate of [REDACTED]*
of processing capacity at the Processing Plant. In addition, to the extent that MarkWest determines in good faith that it can, safely and without unreasonable cost or risk to MarkWest, operate Bluestone 2 in a manner that allows for processing a
volume of Gas in excess of [REDACTED]*, then Producer shall be granted the right to utilize such excess capacity on a priority basis; 

d. Beginning on the [REDACTED]* and until an aggregate of two hundred and eighty five (285) MMcf per day of processing capacity at the
Processing Plant; 
 e. Beginning on the [REDACTED]* and continuing for [REDACTED]*, an aggregate of [REDACTED]* of
processing capacity at the Processing Plant; and 
 f. Beginning on the [REDACTED]* and for the remainder of the term of the
Agreement, an aggregate of four hundred and five (405) MMcf per day of processing capacity at the Processing Plant. 
 If Producer determines that it
requires capacity in excess of its Priority Capacity Rights, and in addition to any additional capacity that results from the Additional Processing Facilities (as defined below) previously installed by MarkWest in accordance with this
Section 6.2 (collectively referred to as “Increased Capacity”), Producer will provide timely written notice to MarkWest of its Increased Capacity requirements and will attempt to provide MarkWest with such notice at least
eighteen (18) months in advance. Producer shall reasonably demonstrate to MarkWest Producer’s drilling plans to support the amount of Increased Capacity, and MarkWest will propose a schedule for providing such Increased
Capacity. Subject to the remaining provisions of this Section 6.2, if the terms, fees and schedule relating to such Increased Capacity are mutually agreed upon by the Parties in writing, MarkWest will, at its sole cost and expense, design,
construct and install expanded or new processing facilities (“Additional Processing Facilities”) to meet Producer’s Increased Capacity requirements and will complete the Additional Processing Facilities as soon as reasonably
practicable. Following the completion of the Additional Processing Facilities, Producer will have Priority Capacity Rights to the Increased Capacity in such Additional Processing Facilities so requested by Producer pursuant to this Section 6.2,
subject to the remaining terms of this Agreement. [REDACTED]*  
 6.3 RESERVED. 

6.4 MarkWest may grant third parties Priority Capacity Rights to the processing capacity in the Processing Plant so long as the aggregate amount of Priority
Capacity Rights granted to Producer and all third parties does not exceed the total processing capacity of the Processing Plant. The Parties acknowledge and agree that during any period when (x) all or any portion of the Facilities is shut down
because of mechanical failure, maintenance or repairs, non-routine operating conditions, or Force Majeure; or (y) Producer’s Gas available for receipt together with Gas of third parties, exceeds the then current capacity of the Facilities;
or (z) MarkWest determines reasonably and in good faith that the operation of all or any portion of the Facilities will cause injury or harm to persons or property or to the integrity of the Facilities, Producer’s Gas may be curtailed or,
if applicable, bypassed around the affected Facilities. In such event, Producer and any other third party whose Gas is delivered to the Processing Plant would be cut back on a pro rata basis based upon Priority Capacity Rights. 

6.5 Should Producer desire any new Redelivery Point(s) other than Dominion Transmission, Inc., the Parties will work together in good faith to mutually agree
upon the manner in which any costs to be incurred in connection with the construction and connection of such new Redelivery Point(s) will be allocated among the Parties. If the Parties cannot mutually agree upon an allocation of such costs, Producer
shall have the right, at its sole expense, to construct such facilities as may be necessary to connect to such new Redelivery Point(s). 
 6.6 The Parties
will work together in good faith to keep the other Party informed in respect of issues of mutual concern including, but not limited to, Producer’s drilling plans and programs and MarkWest’s ongoing operations, construction efforts and
plans, and plans for future expansion, in each case in the Dedication Area. 
 ARTICLE 7: GAS QUALITY 

7.1 As measured at each Receipt Point, Gas delivered by Producer shall be of a quality that, after processing in the Processing Plant as it then currently
exists (and, after the Ethane Service Commencement Date, taking into account any nominations for the recovery of ethane made or deemed to have been made pursuant to the NGL Exchange Agreement), meets the quality specifications of pipelines receiving
Gas at the Redelivery Point(s), as in effect from time to time, other than for water vapor content and hydrocarbon dew point; provided that the water content of Gas delivered by Producer to the Receipt Point(s) shall not include free water. The
receiving pipeline’s existing specifications are set forth on Exhibit C, attached hereto. 
 7.2 The Parties acknowledge that if the
quality standards of the pipelines receiving Gas at the Redelivery Point(s) change, the Parties will consider whether such change is material to this Agreement and, if material, will cooperate with each other to address such change in a manner that
preserves the business and economic objectives of this Agreement. 
 7.3 If Gas tendered by Producer should fail to meet any one or more of the above
specifications from time to time, then: 
 a. MarkWest may take receipt of the non-conforming Gas, and that receipt shall not be construed as
a waiver or change of standards for future Gas volumes; or 

  
 Page 7 of 20 

 b. MarkWest may, at its sole discretion, cease receiving the non-conforming Gas
from Producer, and shall notify Producer that it will cease receiving the non-conforming Gas. Upon such notice to Producer, the non-conforming Gas shall not be deemed Gas delivered to MarkWest by Producer for the purpose of calculating the Demand
Fee in Section 10.1.b of this Agreement. If MarkWest refuses to accept such non-conforming Gas from Producer, the Parties shall negotiate in good faith with respect to the services and facilities necessary to remedy the non-conforming gas and
the fees for MarkWest to provide such services and facilities. If the Parties are unable to agree on such facilities, services and fees within thirty (30) days and if MarkWest refuses to accept non-conforming Gas from Producer, then all (but
only that) Gas that MarkWest refuses to accept for processing shall be released from this Agreement, and the Parties shall have no further obligations to each other with respect to such non-conforming Gas. 

c. If the Gas as delivered contains contaminants not in conformance with the specifications as described in Section 7.1,
then Producer shall be responsible for, and shall reimburse MarkWest for, all actual expenses, damages and costs resulting from MarkWest’s receipt of such non-conforming Gas prior to the time MarkWest becomes aware of such non-conforming Gas.
MarkWest shall be responsible for all actual expenses, damages and costs resulting from all non-conforming Gas accepted by MarkWest after MarkWest becomes aware of such non-conforming Gas. In addition, the Parties acknowledge and agree that,
notwithstanding anything herein to the contrary, (i) “contaminants” as used in this Article 7 shall include, without limitation, toxic substances and polychlorinated biphenyls (collectively, “PCBs”) and (ii) the
expenses, damages, and costs set forth in Section 7.3.c. for which Producer shall be liable in connection with delivering Gas or Raw Make contaminated with PCBs shall include the costs of PCB treating facilities and the costs associated with
treating third party Gas contaminated as a result of Producer’s breach of this Article 7. 
 7.4 As long as Gas delivered by Producer at each Receipt
Point meets the foregoing specifications, or if it does not meet the foregoing specifications but MarkWest nevertheless continues to receive such Gas after becoming aware of the non-conforming Gas, the Residue Gas redelivered by MarkWest at the
Redelivery Point(s) shall meet the quality specifications of the pipelines receiving Gas at the Redelivery Point(s). 
 ARTICLE 8: MEASUREMENT EQUIPMENT
AND PROCEDURES 
 8.1 All Gas measurements required hereunder shall be made with equipment of standard make to be furnished, installed, operated, and
maintained by MarkWest in accordance with the recommendations contained in ANSI/API 2530 as then published. Producer, or others having Producer’s consent, may, at its option and expense, install and operate check measuring equipment upstream of
the measuring equipment to check the measuring equipment, provided the installation of the check measuring equipment in no way interferes with the operation of the measuring equipment. 

8.2 All Gas volume measurements shall be based on an assumed atmospheric pressure of 14.4 psia, regardless of actual atmospheric pressure at which the Gas is
measured. The factors used in computing Gas volumes from orifice meter measurements shall be the latest factors published by the AGA. These factors shall include: 

a. Basic orifice factor. 
 b.
Pressure base factor based on a pressure base of 14.73 psia. 
 c. Temperature base factor based on a temperature base of sixty degrees
Fahrenheit (60°F). 
 d. Flowing temperature factor, based on the flowing temperature as measured by an industry accepted recording
device, if, at MarkWest’s option, a recording device has been installed, otherwise the temperature shall be assumed to be sixty degrees Fahrenheit (60°F). 

e. Super compressibility factor, obtained from the latest AGA Manual for the Determination of Super Compressibility Factors for Natural Gas
(AGA 8). 
 f. Specific gravity factor, based on the specific gravity of the Gas as determined under the provisions set forth below. 

8.3 MarkWest shall test the accuracy of its measuring equipment at least once every calendar quarter. Additional test(s) shall be promptly performed upon
notification by either Party to the other. If any additional test requested by Producer indicates that no inaccuracy of more than two percent (2%) exists, at a recording rate corresponding to the average rate of flow for the period since the
last preceding test, then Producer shall reimburse MarkWest for all its direct costs in connection with that additional test within fifteen (15) days following receipt of a detailed invoice and supporting documentation setting forth those
costs. 

  
 Page 8 of 20 

 8.4 If, upon test, any measuring equipment is found to be in error by an amount not exceeding two percent (2%),
at a recording rate corresponding to the average rate of flow for the period since the last preceding test, previous recordings of that equipment shall be considered correct in computing deliveries hereunder. If the measuring equipment shall be
found to be in error by an amount exceeding two percent (2%), at a recording rate corresponding to the average rate of flow for the period since the last preceding test, then any preceding recordings of that equipment since the last preceding test
shall be corrected to zero error for any period which is known definitely or agreed upon. If the period is not known definitely or agreed upon, the correction shall be for a period extending back one-half of the time elapsed since the last test. In
the event a correction is required for previous deliveries, the volumes delivered shall be calculated by the first of the following methods which is feasible: (i) by using the registration of any check meter or meters if installed and
accurately registering; or (ii) by correcting the error if the percentage of error is ascertainable by calibration, test, or mathematical calculations; or (iii) by estimating the quantity of delivery by deliveries during periods of similar
conditions when the meter was registering accurately. 
 8.5 The composition and Gross Heating Value of any Gas stream required to be measured shall be
determined by MarkWest at least once each calendar quarter, or more often if deemed necessary by MarkWest, by spot samples, or by using a proportionate to flow sampler located at the point where the measurement equipment is located, by
chromatographic analysis, or by some other method mutually acceptable to the Parties. Should Producer request more frequent determinations, the cost of those determinations will be paid by Producer. 

8.6 Each Party, at its sole risk and liability, shall have access at all reasonable hours to all facilities which are related to Gas measurement and sampling.
Each Party, at its sole risk and liability, shall have the right to be present for any installing, reading, cleaning, changing, repairing, testing, calibrating and/or adjusting of either Party’s measuring equipment. The Parties shall cooperate
in obtaining and providing telemetry and similar equipment and systems to provide measurement information to the Parties. 
 ARTICLE 9: ALLOCATIONS

 9.1. Allocations required for determining payments or fees due under this Agreement shall be made by MarkWest in accordance with accepted industry
standards and the following provisions and shall be based upon the measurements taken and quantities determined for the applicable Accounting Period. In addition to other terms defined in this Agreement, the following definitions shall be
applicable: 
 Bypass Point means a point at the Processing Plant where Gas is redirected to bypass the Processing Plant. 

Shrinkage means the total Thermal Content of all Plant Products and Gas used as Fuel, as calculated using GPA 2145 standards. 

Allocations shall be made to each Receipt Point in the manner set forth in this Article 9. For the purposes of this Article 9, it is recognized that Producer
may have more than one Receipt Point and allocations will be made separately to each such Receipt Point. 
 9.2 For purposes of determining Plant Products
attributable to Producer’s Gas, MarkWest shall multiply the volume in Mcf of Producer’s Gas at each Receipt Point by the GPM of each Plant Product contained in the Gas stream at that Receipt Point. The GPM shall be determined by
MarkWest using generally accepted industry standards utilizing chromatograph analysis taken on Gas samples from the Receipt Points. The resulting value will be the “Theoretical Gallons” of that Plant Product in the Gas received
at a receipt point. The “Total Theoretical Gallons” of that Plant Product is the summation of all receipt points Theoretical Gallons of that Plant Product. 

9.3 Subject, in the case of ethane, to the provisions of the NGL Exchange Agreement, each Plant Product shall be allocated to each Receipt Point by
multiplying the total volume, expressed in gallons, of each Plant Product saved and sold by a fraction, the numerator of which shall be the Theoretical Gallons of that Plant Product contained in the Gas at such Receipt Point, excluding Bypass Gas,
and the denominator of which shall be the Total Theoretical Gallons of that Plant Product, excluding Bypass Gas. The Thermal Content of each Plant Product that is allocated to the Receipt Point shall be determined in accordance with the GPA
standards. 
 9.4 Gas that is used as Fuel shall be allocated to each receipt point by multiplying the total Thermal Content of the Fuel by a fraction, the
numerator of which is the Receipt Point Thermal Content attributable to such receipt point, excluding Bypass Gas, and the denominator of which is the Thermal Content of the gas attributable to all receipt points, excluding Bypass Gas. 

9.5 In the event that any Gas is bypassed in accordance with Section 6.4, Bypass Gas Thermal Content for such Gas shall be allocated to each Receipt
Point upstream of the applicable Bypass Point by multiplying the total Bypass Gas Thermal Content at the Bypass Point by a fraction, the numerator of which is the Thermal Content attributable to such Receipt Point and the denominator of which is the
Thermal Content of Bypass Gas attributable to all receipt points upstream of the Bypass Point. 
 9.6 “Theoretical Residue Gas Thermal
Content” means the thermal content of Gas at each receipt point less the thermal content of the Bypass Gas and Shrinkage allocated to the receipt point. Residue Gas Thermal Content available for redelivery at the Redelivery Point(s) shall
be allocated to each receipt point by multiplying that Residue Gas Thermal Content by a fraction, the numerator of which is the Theoretical Residue Gas Thermal Content attributable to such receipt point and the denominator of which is the
Theoretical Residue Gas Thermal Content attributable to all Gas delivered at all receipt points. 

  
 Page 9 of 20 

 9.7 Lost and Unaccounted For Gas shall be allocated to each measurement point pro rata based upon the Thermal
Content of all Gas received at all measurement points during the applicable Accounting Period. Total Lost and Unaccounted For Gas shall be determined by subtracting from the sum of the total Thermal Content of Gas received at all measurement points
during such Accounting Period the sum of (i) the Thermal Content of Gas actually delivered to the Redelivery Point(s) during such Accounting Period and (ii) the Thermal Content of Gas consumed as Fuel measured at all Fuel Points during
such Accounting Period, and (iii) the Thermal Content of all Drip recovered during such Accounting Period. Lost and Unaccounted For Gas for each Accounting Period shall be allocated to each measurement point based upon a fraction, the numerator
of which is the total Thermal Content of Gas measured at such measurement point during such Accounting Period, and the denominator of which is the total Thermal Content of Gas measured at all measurement points during such Accounting Period. As used
in this Section 9.7, “measurement point” shall mean each point at or on the Facilities at which measurement is performed, including the measurement points for Producer’s Gas and all other points at which measurement is
performed for the Gas of third parties that is delivered into the Facilities. 
 9.8 Drip will be handled, recovered and disposed of by MarkWest, at its
expense, and MarkWest will be entitled to retain all drip and the proceeds thereof without accounting to Producer for such. 
 9.9 It is anticipated that
compression and compression cooling, not including the propane condenser, in the Facilities shall initially be engine-driven, fueled by Gas. Prior to the Ethane Service Commencement Date, upon the mutual agreement of the Parties, which agreement
will not be unreasonably withheld or delayed, MarkWest may replace some engines with electrical motors. Following the Ethane Service Commencement Date, MarkWest may, without consent from but with prior notice to Producer, utilize electricity and
electrical motors at its election. Costs for electric power consumed by the electric motors, together with all other electric power consumed by the Facilities, will be allocated to all Gas delivered to the Facilities, and the portion allocated to
Producer shall be deducted from Producer’s compensation under this Agreement. The allocation shall be made to each Receipt Point upstream of the applicable Fuel Point by multiplying the total electric power cost for the Accounting Period by a
fraction, the numerator of which is the Receipt Point volume (in Mcf) attributable to such Receipt Point and the denominator of which is the receipt point volume (in Mcf) attributable to all receipt points delivering Gas to the Facilities during the
Accounting Period. 
 ARTICLE 10: FEES AND CONSIDERATION 

10.1 The amounts described in this Section 10.1 shall be paid to MarkWest by Producer, or by MarkWest to Producer, as applicable. Any amounts payable to
Producer by MarkWest pursuant this Agreement that are based upon Producer’s Gas shall be based on the measurement and allocation procedures set forth in this Agreement. Notwithstanding any provision in this Agreement to the contrary, the
Parties agree that there will be no duplication of any fees, costs, expenses or other charges set forth in this Agreement. 
 a. Subject to
the remaining provisions of this Section 10.1 and the provisions of Section 10.3 below, Producer shall pay MarkWest [REDACTED]* the following (the “Gathering and Processing Fee”): 

[REDACTED]*, as measured at the Receipt Point(s). 

b. [REDACTED]*  
 c.
[REDACTED]*  
 d. The Parties acknowledge that, as of the date hereof, Producer is taking Residue Gas in kind pursuant to
Section 10.2 and Producer shall continue to take all of Producer’s Residue Gas in kind unless and until the Parties mutually agree for MarkWest to market Producer’s Residue Gas and, until such time, MarkWest shall have no obligation
to market Producer’s Residue Gas. The Parties will work together in good faith to develop, and will agree upon in writing, the process and procedures that the Parties will follow in connection with the nomination and scheduling of
Producer’s Residue Gas, including, without limitation, the deadlines for submitting nominations and changes thereto and procedures for minimizing imbalances (such procedures, the “Residue Gas Nomination Procedures”). The
Parties recognize that MarkWest shall be designated by the downstream pipeline carriers at the Redelivery Point(s) as the point operator and shall be considered by such pipeline carriers to be responsible for the operation of MarkWest’s
pipeline interconnections to the pipeline carriers at the Redelivery Point(s). Upon MarkWest entering into operational balancing agreements (“OBAs”) with such pipeline carriers, MarkWest shall be responsible for the administration
of all such OBAs and for all terms and conditions of any such OBA. The Parties recognize that certain Residue Gas imbalances may occur, and each calendar month, the Parties agree to actively communicate and cooperate with each other, and with any
interconnecting pipeline at the Redelivery Point(s), to review appropriate data to identify any imbalance, and to eliminate or remedy any imbalance as soon as either Party becomes aware of an imbalance. The Parties further agree to manage daily
receipts and deliveries so that the imbalances shall be kept as near to zero as practicable. MarkWest will use efforts in accordance with industry standards to manage any imbalances with interconnecting pipeline(s) at the Redelivery Point(s)
physically, but to the extent that any such imbalances are balanced by payments between MarkWest and any such interconnecting pipeline(s) at the Redelivery Point(s), the actual amount of such payment (whether paid by or to MarkWest) will be passed
through to Producer to the extent such imbalances are attributable or related to Producer or Producer’s Gas. Each Party will indemnify and hold harmless the other Party and its Indemnified Parties from any and all costs, expenses,
liabilities, or damages (including without limitation, pipeline imbalances, penalties, court costs, and attorney fees) arising due to any such pipeline imbalances caused by such Party’s failure to comply with the Residue Gas Nomination
Procedures; provided, however, MarkWest shall not be responsible for eliminating any imbalances between Producer and any third party, and MarkWest shall not be required to deviate from MarkWest’s standard operating and accounting procedures to
reduce or eliminate any such imbalances. 

  
 Page 10 of 20 

 10.2 Producer shall have the right to take all or a portion of Residue Gas in kind, subject to the requirements
set forth in this Section 10.2. Producer must provide MarkWest with at least six (6) months prior written notice of its election to take Residue Gas in kind, provided that if MarkWest has, before it receives Producer’s notice, entered
into any contractual arrangements for the sale of any of the Residue Gas for a term that ends after the end of the six (6) month notice period (“Prior Sales Arrangement”), then Producer’s right to take such Residue Gas in
kind shall not begin until the end of such Prior Sales Arrangement with respect to the applicable Residue Gas. Such notice shall identify the effective date of such election, provided that the effective date shall be the first day of a calendar
month. Once the election is made and becomes effective, such election shall remain in effect, and Producer shall be required to continue to take such portion of the Residue Gas in kind, continuously for at least twelve (12) months. 

[REDACTED]* 
 ARTICLE 11: PAYMENTS 

11.1 MarkWest shall provide Producer with a statement explaining fully how all consideration due (including deductions) under the terms of this Agreement was
determined not later than the last day of the Accounting Period following the Accounting Period for which the consideration is due. 
 11.2 MarkWest shall
deduct fees owed by Producer under this Agreement from amounts otherwise due Producer for Residue Gas, if any, and the net amount remaining will be paid no later than the last day of the Accounting Period following the Accounting Period during which
the Gas was delivered hereunder. During any Accounting Period, if no amounts are otherwise due Producer hereunder, then Producer shall pay MarkWest within thirty (30) days of receipt of the statement setting forth such amount. 

11.3 Either Party, on thirty (30) days prior written notice, shall have the right at its expense, at reasonable times during business hours, to audit the
books and records of the other Party to the extent necessary to verify the accuracy of any statement, allocation, measurement, computation, charge, or payment made under or pursuant to this Agreement. The scope of any audit shall be limited to the
twenty four (24) month period immediately prior to the month in which notice is given (“Audit Period”). However, no audit may include any time period for which a prior audit hereunder was conducted, and no audit may occur more
frequently than once each twelve (12) months. Except in the case of material misrepresentation or fraud, all statements, allocations, measurements, computations, charges, or payments made in any period prior to the Audit Period shall be
conclusively deemed true and correct and shall be final for all purposes. To the extent that the foregoing varies from any applicable statute of limitations, the Parties expressly waive all such other applicable statutes of limitations. The Parties
acknowledge and agree that, in connection with any audit hereunder, MarkWest shall not be required to disclose to Producer the names of other MarkWest customers but shall disclose to Producer the settlement terms for those customers to enable
Producer to determine whether MarkWest has complied with its agreement under Section 10.3. 
 ARTICLE 12: FORCE MAJEURE 

12.1 In the event a Party is rendered unable, wholly or in part, by Force Majeure (as hereinafter defined), to carry out its obligations under this Agreement,
other than the obligation to make any payments due hereunder, the obligations of that Party, so far as they are affected by Force Majeure, shall be suspended from the inception and during the continuance of the inability, and the cause of the Force
Majeure, as far as possible, shall be remedied with reasonable diligence. The Party affected by Force Majeure shall provide the other Party with written notice of the Force Majeure event, with reasonably full detail of the Force Majeure and with a
reasonable plan for attempting to overcome or mitigate the effect of any such Force Majeure (to the extent such Force Majeure can be overcome or mitigated) within a reasonable time after the affected Party learns of the occurrence of the Force
Majeure event. The settlement of strikes, lockouts, and other labor difficulty shall be entirely within the discretion of the Party having the difficulty, and nothing herein shall require the settlement of strikes, lockouts, or other labor
difficulty. As used herein, “Force Majeure” shall mean any cause or condition not within the control of the Party claiming suspension (to the extent such cause or condition was not caused by such Party’s gross negligence or
willful misconduct) and which, by the exercise of commercially reasonable diligence, such Party is unable to prevent or overcome, and, without limiting the generality of the foregoing, includes major equipment failures; inabilities or delays,
despite commercially reasonable efforts, in obtaining requisite permits, consents and authorizations; and delays occasioned by governmental actions. Notwithstanding anything to the contrary herein, in the event any Party claims suspension of its
obligations under this Agreement due to an event of Force Majeure for more than 180 days during any 365-day period, then the Party not claiming such event of Force Majeure shall be entitled to terminate this Agreement upon ten (10) days written
notice to the Party claiming such event of Force Majeure. 
 ARTICLE 13: LIABILITY AND INDEMNIFICATION 

13.1 As among the Parties hereto, Producer and any of its designees shall be in custody, control and possession of the Gas hereunder, including, without
limitation, any portion thereof which accumulates as liquids, until that Gas is delivered to the Receipt Point(s) and after any portion of the Gas is redelivered to Producer or for Producer’s account at a Redelivery Point. 

  
 Page 11 of 20 

 13.2 As among the Parties hereto, MarkWest and any of its designees shall be in custody, control and possession
of (i) the Gas hereunder, including, without limitation, any portion thereof which accumulates as liquids, from the delivery of that Gas at the Receipt Point(s) until the Gas is redelivered to Producer at a Redelivery Point and (ii) the
Plant Products and the Fractionated Products to the extent set forth in the NGL Exchange Agreement. 
 13.3 Each Party (“Indemnifying
Party”) hereby covenants and agrees with the other Party, and its Affiliates, and each of their directors, officers and employees (“Indemnified Parties”), that except to the extent caused by an Indemnified Party’s
gross negligence or willful conduct, the Indemnifying Party shall protect, defend, indemnify and hold harmless the Indemnified Parties from, against and in respect of any and all Losses incurred by the Indemnified Parties to the extent those Losses
(i) arise from claims brought by any of the Indemnifying Party’s employees, its contractors or subcontractors, or their employees for Losses due to bodily injury, death, or damage to property or (ii) are not covered by clause
(i) and arise from or are related to: (a) the Indemnifying Party’s facilities and the ownership or operation thereof; or (b) the Indemnifying Party’s possession and control of the Gas and Plant Products. 

ARTICLE 14: TITLE 
 14.1 Producer represents and warrants
that it owns, or has the right to commit, all Gas committed under this Agreement and to deliver that Gas to the Receipt Point(s) for the purposes of this Agreement, free and clear of all liens, encumbrances and adverse claims. If the title to Gas
delivered by Producer hereunder is disputed or is involved in any legal action, MarkWest shall have the right to withhold payment (without interest), or cease receiving the Gas, to the extent of the interest disputed or involved in legal action,
during the pendency of the action or until title is freed from the dispute, or until Producer furnishes, or causes to be furnished, indemnification to save MarkWest harmless from all claims arising out of the dispute or action, with surety
reasonably acceptable to MarkWest. Producer hereby indemnifies MarkWest against and holds MarkWest harmless from any and all Losses arising out of or related to any breach of the foregoing representation and warranty. 

14.2 Title to all Gas shall remain in Producer until such time as the Gas is sold. Except as may otherwise be agreed to in writing by the Parties, title to
the Plant Products shall remain in Producer until such time as the Plant Products are delivered to the NGL Receipt Point. Title to the Fractionated Products allocated to Producer under the NGL Exchange Agreement shall transfer to Producer as set
forth in the NGL Exchange Agreement. 
 ARTICLE 15: ROYALTY AND TAXES 

15.1 Producer shall have the sole and exclusive obligation and liability for the payment of all persons due any proceeds derived from the Gas delivered under
this Agreement, including royalties, overriding royalties, and similar interests, in accordance with the provisions of the leases or agreements creating those rights to proceeds. In no event will MarkWest have any obligation to those persons due any
of those proceeds of production attributable to the Gas under this Agreement. 
 15.2 Producer shall pay and be responsible for all Taxes levied against or
with respect to Producer’s Gas delivered or services provided to Producer under this Agreement, except for any MarkWest local, state or federal income taxes. Except for MarkWest local, state or federal income taxes, MarkWest shall under no
circumstances become liable for Taxes, unless designated to remit Taxes on behalf of Producer by any duly constituted jurisdictional agency having authority to impose such obligations on MarkWest, in which event the amount of Taxes remitted on
Producer’s behalf shall be (a) reimbursed by Producer upon receipt of invoice, with corresponding documentation from MarkWest setting forth such payments, or (b) deducted from amounts otherwise due Producer under this Agreement. 

15.3 Producer hereby agrees to defend and indemnify and hold MarkWest harmless from and against any and all Losses arising from the payments made by Producer
in accordance with Sections 15.1 and 15.2, above, including, without limitation, Losses arising from claims for the nonpayment, mispayment, or wrongful calculation of those payments. 

ARTICLE 16: ASSIGNMENTS 
 16.1 This Agreement shall extend
to and be binding upon the Parties hereto, their successors, and assigns. Subject to the provisions below, this Agreement and the rights, duties or obligations of the Parties hereunder may be assigned or conveyed in whole; provided, however, that
except as set forth in the following sentence, neither Party shall assign or transfer this Agreement and any rights, duties or obligations hereunder, without the prior written consent of the other Party, which consent shall not be unreasonably
withheld. Either Party may make such an assignment or transfer to an Affiliate without seeking the prior written consent of the other Party. A reasonable basis for withholding consent may include (i) the financial condition of the assignee
raising reasonable concern relating to its ability to perform under this Agreement, or (ii) concerns regarding the administration of this Agreement among multiple assignees of Producer unless the assignees appoint an agent to represent them in
connection with this Agreement in a manner reasonably satisfactory to the other Party. All assignments and conveyances of either the wells and leaseholds that are covered by this Agreement or the Facilities shall be subject to this Agreement,
including the foregoing provisions of this Article 16. No assignment shall relieve the assignor of any of its duties or liabilities hereunder which arose prior to such assignment, but the assignee shall assume all duties and obligations of the
assignor arising from and after such assignment and the assignor shall be relieved of such duties and obligations arising from and after such assignment. No transfer of, or succession to, the interest of any Party hereto, either in whole or
partially, shall affect or bind the other Party until the first day of the month following the month in which the other Party shall have received written notification thereof.

 ARTICLE 17: MISCELLANEOUS 

17.1 The failure of any Party hereto to exercise any right granted hereunder shall not impair nor be deemed a waiver of that Party’s privilege of
exercising that right at any subsequent time or times. 
 17.2 This Agreement shall be governed by, construed, and enforced in accordance with the laws of
the Commonwealth of Pennsylvania without regard to choice of law principles. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF
OR RELATING TO THIS AGREEMENT. Any litigation arising out of or in any way related to this Agreement shall be brought and maintained in the state and federal courts having jurisdiction in Pennsylvania. 

17.3 This Section 17.3 shall apply to all disputes between the Parties arising under this Agreement except for disputes pertaining to claims for
indemnification which arise in connection with or grow out of claims asserted against either Party by a third party. A dispute that is subject to this Section 17.3 is referred to herein as a “Dispute.” When a Dispute has
arisen, either Party may give the other Party written notice of the Dispute (“Dispute Notice”). In the event a Dispute Notice is given, the Parties shall attempt to resolve the Dispute promptly by negotiation between executives who
have authority to settle the controversy and who are at a higher level of management than the persons with direct responsibility for the matter. Within ten (10) days after delivery of the Dispute Notice, the receiving Party shall submit to the
other a written response. Thereafter, the executives shall confer in person or by telephone promptly to attempt to resolve the Dispute. All reasonable requests for information made by one Party to the other will be honored. All negotiations and
proceedings pursuant to this Section 17.3 are confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence and any additional confidentiality protections provided by applicable law. If
the Parties have not resolved the Dispute within forty-five (45) days following submission of the Dispute Notice, either Party may file a claim with the American Arbitration Association (the “AAA”) and such Dispute will then be
subject to binding arbitration pursuant to the Commercial Dispute Resolution Rules of the AAA. All in-person arbitration proceedings will be held in Pittsburgh, Pennsylvania. Subject to Section 17.8, the arbitrator(s) may award costs, including
without limitation attorneys’ fees, arbitrator fees, and fees paid to the AAA, to the prevailing Party and shall maintain jurisdiction over the Parties in order to award further costs in connection with seeking any judgment to enforce the award
or in collecting any amount due under the award. 
 17.4 The Parties agree that (a) MarkWest shall keep confidential all information provided by
Producer to MarkWest pertaining to Producer’s exploration and development plans, production forecasts, acreage positions and other non-public information of Producer, and (b) the Parties shall keep the terms of this Agreement confidential
and not disclose the same to any other persons, firms or entities without prior written consent (of Producer in the case of (a) or the other Party in the case of (b)); provided, the foregoing shall not apply to disclosures compelled by law or
court order; or to disclosures to a Party’s Affiliates or such Party’s or its Affiliates’ employees, directors, officers, partners, prospective partners or financing sources, financial advisors, consultants, attorneys, banks, or
institutional investors provided those persons, firms or entities likewise agree to keep this Agreement confidential. 
 17.5 Any change, modification or
alteration of this Agreement shall be in writing, signed by the Parties; and, no course of dealing between the Parties shall be construed to alter the terms of this Agreement. 

17.6 All exhibits and appendices to this Agreement are hereby incorporated into and made part of this Agreement for all purposes. This Agreement, including
all exhibits and appendices, contain the entire agreement between the Parties with respect to the subject matter hereof, and there are no oral or other promises, agreements, warranties, obligations, assurances, or conditions precedent, affecting it.

 17.7 The terms and provisions of this Agreement are for the sole benefit of MarkWest and Producer, and no third party is intended to benefit herefrom
other than the Indemnified Parties. 
 17.8 NO BREACH OF THIS AGREEMENT OR CLAIM FOR LOSSES UNDER ANY INDEMNITY OBLIGATION CONTAINED IN THIS
AGREEMENT SHALL CAUSE ANY PARTY TO BE LIABLE FOR, NOR SHALL LOSSES INCLUDE, ANY DAMAGES OTHER THAN ACTUAL AND DIRECT DAMAGES, AND EACH PARTY EXPRESSLY WAIVES ANY RIGHT TO CLAIM ANY OTHER DAMAGES, INCLUDING, WITHOUT LIMITATION, CONSEQUENTIAL,
SPECIAL, INDIRECT, PUNITIVE OR EXEMPLARY DAMAGES. 
 17.9 This Agreement shall be subject to all applicable federal, state, and local laws, rules,
regulations, and orders affecting either Producer or MarkWest and that pertain to the Facilities or the operation thereof. In the event any one or more of the provisions of this Agreement shall be found to be violative of any applicable order, rule,
or regulation of any regulatory body having jurisdiction, or of any valid law of the United States or any state or other governmental entity having jurisdiction, such provision or provisions shall be deemed to be modified to the extent necessary to
comply with such order, rule, regulation, or law; provided, however, that in the event that a material term under this Agreement is so modified, the Parties will, timely and in good faith, revise and amend this Agreement in a manner which preserves,
as closely as possible, each Party’s business and economic objectives as expressed by the Agreement prior to such modification.

 17.13 If requested, each Party will partially assign to the other Party at no cost, insofar as the granting Party
has the right to do so, single line easements or rights-of-way over, across, and under the lands covered by the granting Party’s leases, right-of-way agreements, or property owned in fee, with full right of ingress and egress, for the purposes
of exercising such requesting Party’s rights or obligations under this Agreement; provided that, (i) the exercise of the rights by the requesting Party under this Section 17.13 will not unreasonably interfere with the granting

Guaranty. Guarantor unconditionally, absolutely, continually and irrevocably guarantees, as principal and not as surety, to MarkWest the punctual and complete payment in full when due of all amounts due from Rex under the Agreement

18.2 Guaranty Absolute. Guarantor hereby guarantees that the Rex Payment Obligations will be paid strictly in accordance with the terms of the
Agreement. The obligations of the Guarantor under this Agreement constitute a present and continuing guaranty of payment, and not of collection or collectability. The liability of the Guarantor under this Agreement shall be absolute, unconditional,
present, continuing and irrevocable irrespective of:

of MarkWest; 
 b. any amendment, waiver, renewal, extension or release of or any consent to or departure from or other action or inaction
related to the Agreement; 
 a. any acceptance by MarkWest of partial payment or performance from Producer; 

b. any bankruptcy, insolvency, reorganization, arrangement, composition, adjustment, dissolution, liquidation or other like proceeding relating
to MarkWest or any action taken with respect to the Agreement by any trustee or receiver, or by any court, in any such proceeding; 
 c. any
absence of any notice to, or knowledge of, the Guarantor, of the existence or occurrence of any of the matters or events set forth in the foregoing subsections (a) through (d); or 

d. any other circumstance which might otherwise constitute a defense available to, or a discharge of, a guarantor. 

18.3 Waiver. Guarantor hereby waives promptness, diligence, presentments, protests and notice of acceptance and any other notice relating to any of the
Rex Payment Obligations and any requirement for MarkWest to protect, secure, perfect or insure any security interest or lien or any property subject thereto or exhaust any right or take any action against the Producer, any other entity or any
collateral. 
 18.4 Continuing Guaranty. This Article 18 is a continuing guaranty and shall (i) remain in full force and effect until the first
to occur of the indefeasible payment in full of all the Rex Payment Obligations for which the Guarantor is responsible, (ii) be binding upon the Guarantor and each of its successors and assigns and (iii) inure to the benefit of and be
enforceable by MarkWest and its successors, transferees and assigns.
