6.1 [Intentionally omitted.]

6.2 Gatherer agrees to take and Shipper agrees to deliver Gas hereunder in accordance with all Laws. Gatherer shall operate and maintain the Gathering System and its related facilities in such a manner as is necessary for Gatherer to provide the gathering and other services hereunder in accordance with the terms and conditions of this Agreement, including the ITC.

6.3 Subject to the terms, conditions and limitations contained herein and in the ITC, Shipper agrees to deliver Gas, or cause Gas to be delivered, from time to time, to the Receipt Point(s), and Gatherer agrees to accept, or cause to be accepted, on a Firm basis, those daily quantities of Shipper’s Gas tendered by or for the account of Shipper, not to exceed the SRC, as set forth in any Individual Transaction Confirmation, and scheduled in accordance with this Article VI. In addition, Gatherer will accept quantities above the SRC on an Interruptible basis in accordance with Section 16.4. Subject to the terms, conditions and limitations contained herein, Gatherer agrees to gather and redeliver, or cause to be gathered and redelivered, (on a Firm basis for quantities equal to or less than the SRC, and on an Interruptible basis (subject to Section 16.4) for quantities above the SRC), the Scheduled Quantity to the Delivery Point. The Scheduled Quantity at the Delivery Point shall be a quantity of Gas equal to the Scheduled Quantity at the Receipt Point(s), less Shipper’s pro rata share of FL&U as determined under the applicable ITC and PTR. Any material variation in flow rate or the Scheduled Quantity will be confirmed in writing via fax or email by Gatherer, with an acknowledgment returned to Gatherer by Shipper.

6.4 Scheduling of receipts and deliveries of Gas between the Receipt Point(s) and Delivery Point shall be in accordance with the Gatherer’s nomination and scheduling procedures set forth in this Section 6.4 and with the nomination and scheduling procedures of the Downstream Transporter. Shipper shall submit Nominations (as defined below) for the gathering of Gas hereunder to Gatherer via Gatherer’s Web-based online nomination system. No later than three (3) Business Days prior to the end of each Month, Shipper shall provide to Gatherer in writing the quantity of Gas (expressed in MMBtu) Shipper expects to make available and deliver at each Receipt Point and receive at the Delivery Point each Day of the following Month (the “Nominations”). Should Shipper desire to change any of the Nominations during such Month, Shipper will use reasonable efforts to notify Gatherer by no later than 8:30 a.m. CCT on the Business Day prior to the Day of the scheduled flow of the capacity and path that the Shipper plans to utilize. The deadline for submitting Nominations is 11:30 a.m. CCT the Business Day prior to the Day of the scheduled flow. Any initial Nomination received after the deadline of 11:30 a.m. CCT on the Business Day prior to the flow Day will be scheduled by Gatherer in its discretion. Gatherer may, in its discretion, allow intraday Nomination changes at the Receipt Point(s) and the Delivery Point. Gas shall be delivered by Gatherer to the Delivery Point in accordance with confirmation by the Downstream Transporter of the Nomination and/or changes to the Nomination (the “Scheduled Quantity”).

6.5 The Parties shall reasonably cooperate with each other to manage and eliminate, as promptly as practical, any variance between the volume of Gas delivered at the Delivery Point for Shipper’s account (i.e., the Scheduled Quantity) and the volume of Gas received at the Receipt Point(s) (less Shipper’s pro rata share of FL&U as determined under the applicable ITC and PTR) (an “Imbalance”). Any physical flow adjustments will be made as agreed to by Gatherer and Shipper (which shall be confirmed in writing via fax or email by Gatherer, with an acknowledgment to be returned to Gatherer by Shipper) to adequately control imbalance levels. The daily and cumulative Imbalance(s) will be determined at the end of each Gas Day. Gatherer may assist Shipper in managing the Imbalance and may, at any time and from time to time, reasonably request in good faith that Shipper change its Nominations at the Delivery Point or, with notice to Shipper, restrict, interrupt, or reduce its receipts or deliveries of Gas at the Receipt Point(s) or Delivery Point, and direct Shipper to make adjustments in its receipts or deliveries, in order to maintain a daily and monthly balance or to correct an Imbalance. If Shipper fails or refuses to follow any such reasonable, good faith request from Gatherer, Gatherer may, without liability hereunder, cease accepting or delivering Gas under this Agreement until the conditions causing the Imbalance are corrected. Imbalances will be cashed-out each Month under the following terms:

(a) If the Imbalance is owed to Gatherer, Shipper shall pay Gatherer, per MMBtu of the Imbalance, one hundred percent (100%) of the arithmetic average of the “Midpoint” prices stated in Gas Daily® (Platts, a division of The McGraw-Hill Companies, Inc.) in the column “Daily Price Survey” for all Days of the Month, for “Tennessee Zone 0 Index” (the “Monthly Average Gas Daily Price”) for the Month in which the Imbalance occurred; or,

(b) If the Imbalance is owed to Shipper, Gatherer shall pay Shipper, per MMBtu of the Imbalance, one hundred percent (100%) of the Monthly Average Gas Daily Price for the Month in which the Imbalance occurred.

If the information necessary to calculate the Monthly Average Gas Daily Price ceases to be available, Shipper and Gatherer shall work in good faith to determine a comparable substitute publication and/or daily posting(s) or other indexes providing comparable data.

ARTICLE VII

ARTICLE VIII

MEASUREMENT

8.1 The measuring facilities shall be designed, installed, operated, and maintained by Gatherer or its designee in accordance with the following standards:

(a) Orifice Measurement - American Gas Association Report Number 3, dated 2000 or the most recent edition as agreed to by all Parties (herein referred to as AGA 3).

(b) Turbine Measurement - American Gas Association Report Number 7, dated 1996 or the most recent edition as agreed to by all Parties (herein referred to as AGA 7).

(c) Positive Measurement - American National Standards Institute B109.2, dated 2000 or the most recent edition as agreed to by all Parties (herein referred to as ANSI B109.2).

(d) Ultrasonic Measurement - American Gas Association Report Number 9, dated 2003 or the most recent edition as agreed to by all Parties (herein referred to as AGA 9).

(e) Electronic Gas Measurement — American Petroleum Institute Chapter 21.1, dated 2005 or the most recent edition as agreed to by all Parties (herein referred to as API 21.1).

8.2 Shipper may, at its option and expense, install and operate meters, instruments and equipment, in a manner that will not interfere with Gatherer’s equipment, to check Gatherer’s meters, instruments, and equipment, but the measurement for the custody transfer of Gas for the purpose of this Agreement will be by Gatherer’s meter only, except as hereinafter specifically provided. The meters, check meters, instruments, and equipment installed by each Party will be subject at all reasonable times to inspection or examination by the other Party, but the calibration and adjustment thereof will be done only by the installing Party. Gatherer shall provide Shipper with near real time access to flow information at each Receipt Point.

8.3 All meters will be calibrated and or proven on a mutually agreed schedule, but not less often than Monthly, ensuring that the meter calibration or proving frequency is in compliance with regulatory requirements. Notification of scheduled calibrations shall be made to all interested parties and reasonable effort will be made to accommodate each Party’s schedule; however, calibration will proceed at the scheduled time regardless of attendees. Records from all measuring equipment are the property of Gatherer who will keep all such records on file for a period of not less than two (2) years. Upon request, Gatherer will make available to Shipper volume records from the measuring equipment, together with calculations therefrom, for inspection and verification, subject to return within thirty (30) Days after receipt thereof by Shipper.

8.4 Either Party shall have the right to conduct such pulsation tests as they deem prudent, at the testing Party’s sole risk and expense. If excessive pulsation is evident, mutually agreed modifications to operation or facility design will be made to reduce the effect of such pulsation.

8.5 If the percentage of inaccuracy from the results of any test is greater than two percent (2%), the registration of such meter shall be corrected at the rate of such inaccuracy for any period which is definitely known or agreed upon. In the event the period is not definitely known or agreed upon, such correction shall be for a period extending back one-half (1/2) of the time elapsed since the date of the last calibration. Following any test, measurement equipment found inaccurate shall be immediately restored by Gatherer as closely as possible to a condition of accuracy. If any measurement equipment is out of service or out of repair for any reason so that the amount of Gas delivered cannot be estimated or computed from the reading thereof, the amount of Gas delivered through such meter during the period such meter is out of service or out

of repair shall be estimated and agreed upon by Gatherer and Shipper upon the basis of the best data available using the first of the following methods which is feasible:

(a) by using the registration of any check meters if installed and accurately registering;

(b) by correcting the error if the percentage of error is ascertainable by calibration, test or mathematical calculation; or

(c) by estimating the quantity of deliveries by comparison with deliveries during preceding periods under similar conditions when the meter was known to be registering accurately.

8.6 Measurement Volume Computations

(a) The unit of volume of Gas shall be one (1) standard cubic foot at a base pressure of fourteen and sixty-five hundredths pounds per square inch absolute (14.65 p.s.i.a.) and at a base temperature of sixty degrees Fahrenheit (60°F). The energy content may be recalculated, if the water vapor of the Gas is determined to be greater than seven (7) pounds of water vapor per one million (1,000,000) standard cubic feet, by adjusting the measured volume to correct for the volume of water vapor assuming saturation at the temperature and pressure of measurement (as delivered) and multiplying the corrected volume by the gross dry heating value.

(b) Atmospheric pressure shall be assumed to be the pressure value as reasonably determined by Gatherer for each Receipt Point and Delivery Point location pursuant to generally accepted practices.

8.7 Records of calibration and or proving and data associated with the volume calculation, and the records and data relating to the sampling and determinations under Sections 8.8 and 8.9 below, are the property of Gatherer who will keep all such records and data on file for a period of not less than two (2) years. Upon request, Gatherer will make available to Shipper all such records and data (including an electronic measurement audit package that complies with API Chapter 21.1 Measurement, if offered by Gatherer), subject to return within thirty (30) Days after receipt thereof by Shipper.

8.8 Gatherer shall sample and determine the Gross Heating Value, relative density and compressibility at the Receipt Point(s), at the measurement facilities at the inlet of the Plant as defined in the Processing Agreement, and at the Delivery Point utilizing the following standards:

(a) Gas Processors Association (GPA) 2166 - Obtaining Natural Gas Samples for Analysis by Gas.

(b) Gas Processors Association (GPA) 2261 - Analysis for Natural Gas and Similar Gaseous Mixtures by Gas Chromatography.

(c) Gas Processors Association (GPA) 2145 - Physical Constants for Paraffin Hydrocarbons and Other Components of Natural Gas.

CREDIT ASSURANCE

14.1 Each Party acknowledges and agrees that the other Party’s credit as of the date of this Agreement is satisfactory. In the event a material adverse change occurs in a Party’s credit (the “Affected Party”) and the other Party (the “Requesting Party”) determines the Affected Party’s credit to be unsatisfactory in Requesting Party’s sole and reasonable opinion at any time during the term of this Agreement, the Requesting Party may demand “Adequate Assurance of Performance” from such Affected Party which shall mean sufficient security in an amount and for a term reasonably specified by the Requesting Party; provided, however, in no event shall the amount of such security exceed the greater of (i) the amount owed hereunder by such Affected Party for the most recent two (2) Months, or (ii) the amount estimated by the Requesting Party in good faith to be owed hereunder by such Affected Party for the next succeeding two (2) Months based on deliveries by Shipper equal to the SRC. Such Affected Party at its option may then provide one of the following forms of security:

(a) Provide a written guaranty of payment from an Affiliate with credit satisfactory to the Requesting Party with such guaranty of payment to be provided in a form and for a term acceptable to the Requesting Party, but such guaranty of payment shall constitute Adequate Assurance of Performance only for as long as the credit of the Affiliate continues to be satisfactory to the Requesting Party;

(b) Post an irrevocable standby letter of credit in a reasonably satisfactory form and from a bank satisfactory to the Requesting Party; or,

14.2 Should such Affected Party fail to provide Adequate Assurance of Performance within two (2) Business Days after receipt of written demand for such assurance, then the Requesting Party shall have the right to suspend performance under this Agreement until such time as such Affected Party furnishes Adequate Assurance of Performance. If such assurance is not provided by such Affected Party within ten (10) Business Days from written demand, the Requesting Party may terminate this Agreement in addition to having any and all other remedies available hereunder, at law or in equity.

ARTICLE XVI

FORCE MAJEURE

16.1 Suspension of Obligations. In the event a Party is rendered unable, wholly or in part, by Force Majeure to carry out its obligations under this Agreement, other than the obligation to make payments then or thereafter due hereunder, and such Party promptly gives notice and reasonably full particulars of such Force Majeure in writing to the other Party after the occurrence of the cause relied on, then the obligations of the Party giving such notice, so far as and to the extent that they are affected by such Force Majeure, shall be suspended during the continuance of any inability so caused, but for no longer period, and such cause shall so far as reasonably possible be remedied with all reasonable dispatch by the Party claiming Force Majeure. In addition, the Party claiming Force Majeure shall resume performance of any such suspended obligations promptly after termination of such Force Majeure. Shipper shall have the right to secure alternate gathering services from third parties during Force Majeure events that affect Gatherer’s ability to provide gathering services hereunder, but only for so long as and only to the extent that such Force Majeure event prevents Gatherer from providing gathering services hereunder.

16.2 Force Majeure. The term “Force Majeure,” as used in this Agreement, shall mean any cause or causes not reasonably within the control of the Party claiming suspension and which, by the exercise of reasonable diligence, such Party is unable to prevent or overcome, including, without limitation, acts of God, strikes, lockouts, or other industrial disturbances, acts of a public enemy, sabotage, wars, blockades, insurrections, riots, acts of terror, epidemics, landslides, lightning, earthquakes, fires, storms, storm warnings, floods, washouts, arrests and restraints of governments and people, civil disturbances, maintenance, explosions, breakage or accident to equipment installations, machinery or lines of pipe, and associated repairs, freezing of lines of pipe, pipes or other delivery facilities, electric power unavailability or shortages, failure of pipelines or carriers to transport, delay or curtailment of natural gas liquid transportation or fractionation services, inability to obtain or timely obtain, or obtain at a reasonable cost, after exercise of reasonable diligence, pipe, materials, equipment, rights-of-way, servitudes, governmental approvals, or labor, including those necessary for the facilities provided for in this Agreement, and any legislative, governmental or judicial actions. Examples of Force Majeure may also include curtailment or interruption of deliveries, receipts or services by third party purchasers, suppliers or customers as a result of an event of Force Majeure or a breach by such third party purchasers, suppliers or customers. It is understood and agreed that the settlement of strikes or lockouts shall be entirely within the discretion of the Party having the

difficulty, and that the above requirement that any Force Majeure shall be remedied with reasonable dispatch shall not require the settlement of strikes or lockouts by acceding to the demands of the opposing party when such course is inadvisable in the sole discretion of the Party having the difficulty

16.3 Limitation on Force Majeure. Neither Party shall be entitled to the benefits of the provision of Force Majeure to the extent performance is affected by any or all of the following circumstances: (i) the Party claiming excuse failed to remedy the condition and to resume the performance of its covenants or obligations with reasonable dispatch except as to strikes or industrial lockouts; or (ii) economic hardship, to include, without limitation, Shipper’s ability to sell its Gas at a higher or more advantageous price to a market not requiring the gathering or other services contracted for herein; or (iii) the loss of Shipper’s market for Gas.

16.4 Curtailment or Suspension. If and to the extent Gatherer curtails or suspends the gathering of Gas on the Gathering System due to Force Majeure or any other reason, Gas tendered to the Receipt Point(s) by or for the account of Shipper, up to the SRC, shall have the highest priority for gathering on the Gathering System together with all other Gas being gathered on a firm basis (i.e., gathering of Gas up to a shipper’s applicable daily reserved capacity on the Gathering System is not subject to interruption) for other shippers under agreements executed and dated on or before April 15, 2011, pro rata, and shall not be curtailed or suspended from gathering if other Gas is being gathered on the Gathering System on an interruptible basis. Similarly, Gas tendered to the Receipt Point(s) by or for the account of Shipper, in excess of the SRC, shall have the highest priority for gathering on the Gathering System on an interruptible basis (i.e., interruptible by Gatherer in its sole discretion) together with all other Gas being gathered on an interruptible basis for other shippers under such agreements executed and dated on or before April 15, 2011, pro rata. Gatherer shall remedy any Force Majeure event and any other cause of curtailment or suspension with all reasonable dispatch, and in such a manner as to minimize any adverse impact on Shipper hereunder. Gatherer shall provide only two levels of service on the Gathering System, firm and interruptible, each as defined above.

ARTICLE XVII

TERM AND TERMINATION

17.1 Effective Date and Term. This Agreement shall govern any and all Transactions and shall be in effect for a term of five (5) year(s) from the Effective Date (the “Primary Term”).

INDIVIDUAL TRANSACTION CONFIRMATION

GATHERING AND NATURAL GAS SERVICES AGREEMENT

BETWEEN SM ENERGY COMPANY AND

ETC TEXAS PIPELINE, LTD.

DATED APRIL 1, 2011

BASE AGREEMENT: Gathering and Natural Gas Services Agreement dated April 1, 2011, Contract No. 11515-100, between Shipper and Gatherer identified below.

INDIVIDUAL TRANSACTION NUMBER: 11515-101

SHIPPER: SM ENERGY COMPANY

GATHERER: ETC TEXAS PIPELINE, LTD.

This Individual Transaction Confirmation (this “ITC”) constitutes part of the terms and provisions of the Base Agreement (collectively, the “Agreement”). All capitalized terms not defined herein shall have the meaning ascribed to such terms in the Base Agreement.

TYPE OF SERVICE: Firm up to Shipper’s Reserved Capacity (“SRC”); Interruptible for volumes greater than the SRC.

CONSTRUCTION OF GATHERING SYSTEM: Gatherer has constructed or shall construct pipeline facilities from the Briscoe and Galvan Receipt Point(s) (defined below) to an interconnect with a new pipeline (the “Rich Eagleford Mainline” or “REM”) at least 24 inches in diameter which Gatherer shall construct from a point in Dimmit County, Texas, to connect to the inlet of a new gas processing plant Gatherer shall build in Jackson County, Texas (the “Jackson Plant”). Such upstream pipeline facilities, REM, the Briscoe and Galvan Receipt Point(s), and the Jackson Plant are collectively referred to herein as the “Facilities”). The approximate location of the Facilities is depicted on Exhibit A attached hereto and made a part hereof.

PROJECT TIMING: The Facilities shall be completed, ready to receive Gas under the Agreement and that certain Gas Processing Agreement between Gatherer and Shipper of even date herewith (the “Processing Agreement”), and placed in commercial service on or before July 1, 2013. Neither Party shall have any obligation to deliver or receive Gas hereunder until such time as the Facilities are completed, ready to receive Gas under the Agreement and the Processing Agreement, and placed in commercial service (the “In-Service Date”). Until the In-Service Date, Gatherer shall keep Shipper reasonably informed as to the status of acquisition and construction of the Facilities (including rights-of-way) and progress towards completion, and such information shall include at least quarterly written updates through July 1, 2012, and monthly written updates thereafter, as to such status and completion of milestones. Gatherer shall give Shipper written notice when the In-Service Date occurs. If the In-Service Date does not occur on or before September 1, 2013, for any reason (including Force Majeure), Shipper shall have the right to terminate, by written notice to Gatherer delivered on or before October 1, 2013, the Agreement and the Processing Agreement, without any liability or obligation to Gatherer.

SRC:

Period		Shipper’s Reserved Capacity
In-Service Date - June 30, 2013		Interruptible Service
July 1, 2013 – June 30, 2014		[*****] MMBtu per Day
July 1, 2014 - June 30, 2015		[*****] MMBtu per Day
July 1, 2015 – June 30, 2023		240,000 MMBtu per Day

Subject to any commitments existing as of the Effective Date (including any minimum delivery commitments), Shipper shall, during the period July 1, 2013 through December 31, 2015, deliver all Gas on Shipper’s gathering systems capable of delivering gas to the Receipt Point(s) (without re-configuring or adding additional facilities) to the Receipt Point(s) for gathering services hereunder, up to the SRC.

VOLUMETRIC COMMITMENT: Beginning July 1, 2013, if during any semi-annual period beginning July 1 or January 1, for any reason (including Force Majeure), Shipper delivers to the Receipt Point(s) for gathering under this ITC an average daily quantity of Gas less than the stated MMBtu per Day set forth below during the applicable period (the “Minimum Daily Quantity” or “MDQ”), then Shipper shall pay Gatherer an amount equal to the product of (a) the difference between (i) the product of the number of Days in such semi-annual period multiplied by the Minimum Daily Quantity (the “Minimum Semi-Annual Quantity”) and (ii) the sum of the actual quantity of Gas delivered to the Receipt Point(s) for gathering under this ITC during such semi-annual period, multiplied by (b) $[*****] per MMBtu (the “Deficiency Fee”).

Period		MDQ
July 1, 2013 through June 30, 2014		[*****] MMBtu per Day
July 1, 2014 through June 30, 2015		[*****] MMBtu per Day
July 1, 2015 through June 30, 2023		[*****] MMBtu per Day

Such payment shall be calculated following the end of each such semi-annual period and shall be due within thirty (30) Days following invoice by Gatherer. Any quantities of Gas delivered and/or credited under this ITC during a semi-annual period in excess of the Minimum Semi-Annual Quantity for such semi-annual period will be credited against the Minimum Semi-Annual Quantity for the succeeding semi-annual period(s). In addition, any quantities of Gas delivered under this ITC prior to July 1, 2013, will be credited against the Minimum Semi-Annual Quantity for the semi-annual period commencing July 1, 2013.

If the In-Service Date does not occur on or before July 1, 2013, for any reason (including Force Majeure) and Shipper is ready to deliver Gas to the Receipt Point(s), then Shipper shall receive (y) a credit against the applicable Minimum Semi-Annual Quantity equal to the product of the applicable SRC multiplied by the number of Days the In-Service Date is late beyond July 1, 2013, and (z) free services under the Agreement (i.e., no obligation to pay any Gathering Fee(s)), up to the MDQ each Day, for a period of Days equal to the number of Days beyond July 1, 2013, that the In-Service Date is delayed.

In determining whether any Minimum Semi-Annual Quantity has been met, Shipper shall receive a one (1) MMBtu credit against such Minimum Semi-Annual Quantity for each one (1) MMBtu of Gas which Shipper was ready and able to deliver hereunder in accordance with the Agreement during the applicable semi-annual period (as determined by reference to the weighted average daily quantity of such deliveries (in MMBtu) during the five (5) Days immediately preceding Gatherer’s failure to receive such gas; provided that if the SRC changes during such five-Day period, the determination shall be made by reference to the weighted average daily quantity of such deliveries (in MMBtu) during the number of Days after such change) but which Gatherer failed to receive for any reason (including Force Majeure); provided, however, such credit shall not exceed for any Day a quantity of Gas equal to the SRC less the quantity of Gas (in MMBtus) which was delivered hereunder during such Day.

Beginning June 30, 2015, if the average daily quantity of Gas delivered by Shipper to the Receipt Point(s) for gathering hereunder during any semi-annual period thereafter (including the quantities of Gas, if any, credited hereunder due to Gatherer’s failure to receive Gas for any reason (including due to Force Majeure declared by Gatherer) during such semi-annual period) (the “ADQ”) is less than the applicable SRC, then Gatherer, may upon thirty (30) Days’ prior written notice to Shipper, reduce such SRC to the greater of (a) such ADQ or (b) the simple average of such SRC and the applicable MDQ; provided, however, Shipper may elect to avoid such reduction if, within such thirty (30) Day notice period, Shipper provides Gatherer with written notice that Shipper has elected to avoid such reduction by increasing such MDQ, on a prospective basis, to such simple average.

TERM: This ITC is effective on the date of execution of this ITC and shall continue for a primary term ending ten (10) years from July 1, 2013 (the “Primary Term”), and shall thereafter continue in effect from year to year, until terminated by Shipper or Gatherer giving the other Party written notice at least one hundred twenty (120) Days prior to the end of the Primary Term or any annual term thereafter.

RECEIPT POINT(S): Gatherer shall install a tap, measurement facilities, and piping capable of receiving up to 140,000 MMBtu per Day at each of (1) an interconnect with Shipper’s gathering system and Gatherer’s Las Bonitas Pipeline (the “Briscoe Receipt Point”) located at Latitude 28° 10.863’N; Longitude 99° 52.368’W, and (2) an interconnect with Shipper’s gathering system and Gatherer’s Dos Hermanas Pipeline (the “Galvan Receipt Point”) located at Latitude 28° 3.870’N; Longitude 99° 36.420’W, each in Webb County Texas Shipper shall provide Gatherer a site suitable for Gatherer’s facilities at the Galvan Receipt Point. In addition, Gatherer shall install, at its sole cost and expense, a tap for an additional Receipt Point(s) at a mutually agreeable location when requested by Shipper on the then-existing Las Bonitas 24-inch or REM 30-inch pipelines, in which event Shipper will be responsible for installing, at its sole cost and expense, such lines and other facilities as are necessary to connect Shipper’s gathering system to such additional Receipt Point(s). Gatherer shall install chromatographs and electronic flow measurement with telemetry at each of the Receipt Point(s), and Shipper shall reimburse Gatherer for the cost of installing all facilities upstream of the tap at such third Receipt Point. All facilities located downstream of the inlet flange of the measurement facilities at each Receipt Point shall be owned, operated and maintained by Gatherer. The maximum allowable operating pressure at the Briscoe and Galvan Receipt Point(s) shall be 1300 psig and 1238 psig, respectively, and the operating pressure at the Briscoe and Galvan Receipt Point(s) shall not exceed 1200 psig.

RECEIPT POINT(S) SETTLEMENT: Pursuant to the Processing Agreement, Shipper shall receive (and sell to Gatherer) 100% of the Plant Products attributable to Producer’s Gas and 100% of the Residue Gas (as such terms are defined in the Processing Agreement) as determined pursuant to the Processing Agreement.

DELIVERY POINT: The Delivery Point as defined in the Processing Agreement.

CONDENSATE: Gatherer shall pig the Facilities upstream of the Plant as it deems necessary and shall retain all Condensate that is collected as a liquid in the Facilities downstream of the Receipt Point(s) and upstream of the Plant. Title in such Condensate shall vest in Gatherer at the point(s) at which it is collected or extracted from such Facilities.

GATHERING FEES: $[*****] per Receipt Point(s) MMBtu for all quantities up to the SRC (the “Firm Gathering Fee”).

$[*****] per Receipt Point(s) MMBtu for all quantities greater than the SRC (the “Interruptible Gathering Fee”).

However, at the time the total quantity of Gas delivered to the Receipt Point(s) for gathering under this ITC equals [*****] MMBtu, such Gathering Fee(s) shall each be reduced by $[*****] per MMBtu for all quantities of Gas delivered to the Receipt Point(s) hereunder in excess of such total quantity. In such event, subject to any commitments existing as of the Effective Date (including any minimum delivery commitments), Shipper shall, during the remaining Primary Term of this ITC, deliver all Gas on Shipper’s gathering systems capable of delivering gas to the Receipt Point(s) (without re-configuring or adding additional facilities) to the Receipt Point(s) for gathering services hereunder, up to the SRC.

FEE ESCALATION: Beginning with the first Day of the second Contract Year, and annually thereafter (the “Escalation Date”), [*****] percent ([*****]%) of the Gathering Fees and [*****] percent ([*****]%) of the Deficiency Fee shall be increased by a percentage equal to the percentage of increase change between:

(a) the seasonally unadjusted Consumer Price Index for All Urban Consumers (all items), U.S. city Average (1982-84 = 100), as published by the U.S. Department of Labor, Bureau of Labor Statistics (“CPI-U”) for the month of December of the second year prior to the Escalation Date; and

(b) the seasonally unadjusted CPI-U for the month of December immediately preceding the Escalation Date (the “CPI Adjustment”); provided, however, no such annual percentage increase shall exceed [*****] percent ([*****]%).

For example, the CPI-U published for December 2000 was 174.0 and the CPI-U published for December 2001 was 176.7, resulting in a percentage change of [*****]% as of January 1, 2002.

FL&U: Shipper’s pro rata share of actual FL&U (including electricity cost) on the Gathering System; provided however, FL&U shall not exceed [*****] percent ([*****]%) of the MMBtu

delivered to the Receipt Point(s) hereunder. For the avoidance of doubt, FL&U under this ITC does not include PTR.

GAS QUALITY: The Gas delivered by Shipper at each Receipt Point shall have a Gross Heating Value of not less than one thousand one hundred (1,100) Btu’s per cubic foot and shall contain no less than [*****] gallons per Mcf of natural gas liquids (“GPM”). If the GPM of the Gas delivered by Shipper at the Receipt Point(s) is less than [*****] GPM (calculated on a weighted average basis at all Receipt Point(s) in the aggregate), then for the period of such deliveries, the Gathering Fees shall increase in accordance with the following formula:

Increased Fee = Fee x [1 + ([*****] GPM – actual GPM)/ [*****] GPM]
