EASEMENTS

A. To the extent that it may contractually or lawfully do so under its leasehold interest without impairing its own similar right. Seller hereby assigns and transfers to Buyer/Processor any easement across the Seller's Leases, and across any adjoining lands in which Seller may have an interest, for the purposes of installing, using, inspecting, repairing, operating, replacing, and/or removing Buyer/Processor's pipe, meters, lines, and other equipment used or useful in the performance of the Agreement, It is intended that any property of Buyer/Processor placed in or upon any of such land shall remain the personal property of Buyer/Processor, subject to removal by it upon the expiration or termination of the Agreement for any reason. Buyer/Processor shall have a reasonable time after the expiration or termination of the Agreement to remove same. Buyer/Processor shall defend (with counsel reasonably acceptable to Seller), indemnify and hold Seller harmless of and from any and all claims and damages for all injuries to persons, including death, or damage to property arising out of or incident to Buyer/Processor's use of the easement hereunder transferred, only in the event said claim or damage shall be the result of negligence legally imputable to Buyer/Processor, its employees, agents, and representatives.

SHRINKAGE

A. Buyer/Processor agrees to use ordinary care in transporting Seller's Gas from the Point(s) of Delivery to the Gas Plant, and after processing Seller's Gas, delivering the resultant Residue Gas to its purchaser at the tailgate of the Gas Plant.

8.	GAS MEASUREMENT AND QUALITY

A. Buyer/Processor shall furnish and install a suitable orifice meter at the Point(s) of Delivery of the Gas covered hereby. Each meter installed by Buyer/Processor shall be a meter acceptable in the industry and each mater shall be installed and operated in accordance with the requirements of applicable provisions in ANSI/API 2530, “Orifice Metering of Natural Gas” (American Gas Association Gas Measurement Committee Report No. 3) of the Natural Gas Department of the American Gas Association, as amended from time to time, or by any other method commonly used in the industry and mutually acceptable to the Parties, Any meter installed hereunder shall be open to inspection by Seller at ail reasonable times. The charts and records pertaining to measurement hereunder shall be kept on file by Buyer/Processor for a period of two (2) years for the mutual use of the Parties. In the event any question arises as to the accuracy of the measurement, the meter or meters shall be tested upon the demand of either Party. The expense of any such special test shall be borne by the Party demanding same if the meter registration is found to be correct, and by Buyer/Processor if found to be incorrect.

4 B

B. Seller may, at its option and sole expense, install, maintain and operate check meters and other equipment to check Buyer/Processor's meters; provided, however, that such check meters and other equipment shall be installed by Seller so as not to interfere with the operation of any of the Facilities.. Buyer/Processor and Seller shall have access to each other's measuring equipment at all times during business hours, but the reading, calibrating and adjustment thereof and the changing of charts shall be done only by the employees or agents of Buyer/Processor and Seller, respectively, as to meters or check meters so installed hereunder.

C. At least semi-annually Buyer/Processor shall calibrate all meters installed hereunder and make adjustments as necessary. Should Seller so desire, Buyer/Processor shall give notice to Seller of the time of such calibrations sufficiently in advance of holding same in order that Seller may have its representative present. With respect to any test made hereunder, a registration within two percent (2%) of correct shall be considered correct. However, the meter or meters, when found to be incorrect, shall be adjusted to one hundred percent (100%) accuracy as soon as possible. Settlement for any period during which the meter registration deviates by more than two percent (2%) of correct shall be corrected at the rate of inaccuracy for any period of inaccuracy which is definitely known or agreed upon; but in case the period is not definitely known or agreed upon, then either for a period of fifteen (15) days prior to the date of said test, or for a period calculated from the beginning of the Accounting Period in which the test was conducted, whichever is longer. The rate of the inaccuracy shall be estimated and agreed upon by the Parties hereto on the basis of the best available data, using the first of the following methods which is feasible:

By using the registration of any check meter or meters if installed and accurately registering; or, in the absence thereof,

By calibration, test, or mathematical calculation; or

By estimation based on comparison of the quantity of deliveries with deliveries during preceding periods under similar conditions when the meter was registering accurately.

D. All fundamental constants, observations, records and procedures involved in the determination and/or verification of the quantity and other characteristics of Gas measured hereunder, unless otherwise specified herein, shall be In accordance with the applicable provisions in ANSI/API 2530, "Orifice Metering of Natural Gas" (American Gas Association Gas Measurement Committee Report No. 3) of the Natural Gas Department of the American Gas Association, as amended from time to time, or by any other method commonly used in the industry and mutually acceptable to the Parties. The average local atmospheric pressure shall be assumed to be 12.3 Psia. The temperature of Gas flowing through each meter shall be determined by a recording thermometer, installed by Buyer/Processor at its sole cost and expense to properly record the temperature of the flowing Gas, and the arithmetical average of the temperature recorded while the Gas is flowing during each meter chart interval shall be used in correcting amounts delivered hereunder to a temperature base of sixty degrees Fahrenheit (60°F) and to a pressure base of 14.65 pounds Psia.

E. Seller agrees that all Gas delivered to Buyer/Processor under the Agreement shall:

Contain not more than one-fourth (¼) grain of hydrogen sulfide per one hundred (100) cubic feet of Gas, or more than five (5) grains of total sulfur per one hundred (100) cubic feet of Gas;

Contain not more than two percent (2%) by volume of carbon dioxide, nor more than three percent (3%) by volume of nitrogen, nor more than two-tenths percent (0.2%) by volume of oxygen;

Not have a maximum temperature greater than one hundred twenty degrees Fahrenheit (120°F), or a minimum temperature less than forty degrees Fahrenheit (40°F); and

Be commercially free of all objectionable dust or other solid or liquid or gaseous matters which might interfere with its merchantability or cause injury to or interference with proper operations of any of the Facilities through which the Gas flows.

5 B

F. Buyer/Processor may test Seller's Gas delivered hereunder for adherence to the specifications above set forth, such testing to be in accordance with generally accepted industry standards and procedures. If the Gas so delivered by Seller does not meet the specifications set forth above. Buyer/Processor, at its option, may refuse to accept delivery of said Gas into its Facilities, or may accept such Gas, provided that measured volumes of such Gas shall be reduced by the amount by which the total volume of inert components exceed five percent (5%) as set forth above. If Seller shall deliver Gas to Buyer/Processor which exceeds the maximum pressure specifications or fails to meet the quality specifications for any given Delivery Point, Seller shall be responsible for any damages caused to Buyer/Processor's Facilities and any other damages as a result of Seller's delivery of such nonconforming Gas.

G. At least annually, Buyer/Processor shall take samples from each of Seller's Xxxxx at the Delivery Points and have such samples analyzed by chromatograph analysis to determine the liquids content by component and the heating value of such Gas. Buyer/Processor shall have the right to take and analyze a spot Gas sample prior to the regularly scheduled sampling. Additionally, upon Seller's written request to Buyer/Processor and at Seller's sole cost, risk and expense, Buyer/Processor shall take and analyze Gas samples more frequently, All Gas samples taken hereunder shall be taken at such times that are reasonably mutually agreeable so that the sample will be representative of the Gas produced, shall be analyzed using the most current Gas Processor's Association Publications and Seller shall be permitted to be present for such sampling and permitted to take a split sample. Heating values determined by calculation from compositional analysis according to GPA Standard 2172-84 (or latest revision) shall be converted to values that reflect the actual condition of the Gas on delivery as adjusted for pressure, water content, and compressibility unless otherwise prescribed by statute. Gas produced and not dehydrated at point of measurement shall be considered to be saturated with water at measurement temperature and pressure unless determined otherwise. For the purpose of making Btu calculations, Gas which contains seven (7) pounds of water or more per Mcf shall constitute wet gas and Gas which contains less than seven (7) pounds of water per Mcf shall constitute dry gas. Any chromatograph analysis taken hereunder shall be effective for Gas delivered commencing on the first day of the next succeeding month and shall not be effective retroactively unless otherwise mutually agreed by the Parties.

9.	ALLOCATION OF RESIDUE GAS AND PI ANT PRODUCTS REVENUES

A. For the purpose of determining the Residue Gas MMBtu's attributable to Producer's Gas, Gatherer/Processor shall calculate a fraction, the numerator being the Theoretical Residue MMBtu's of Gas attributable to each of Producer's Xxxxx and the denominator being the total Theoretical Residue MMBtu's of all Gas received and processed-by Gatherer/Processor, This fraction shall be multiplied by the total Residue Gas MMBtu's available at the tailgate of the Gas Plant to determine the Residue Gas attributable to each of Producer's Xxxxx.. Residue Gas attributable to each of Producer's Xxxxx shall be allocated to Gatherer/Processor and Producer pursuant to the Gathering and Processing Fees provisions contained herein.. For the purpose of making Btu calculations, Gas which contains seven (7) pounds of water or more per Mcf shall constitute wet gas and Gas which contains less than seven (7) pounds of water per Mcf shall constitute dry gas. Any chromatograph analysis taken hereunder shall be effective for Gas delivered commending on the first day of the next succeeding month and shall not be effective retroactively unless otherwise agreed by the Parties.

B. Theoretical Residue MMBtu's attributable to each of Producer's Xxxxx shall be determined by calculating the MMBtu's measured at each of Producer's Xxxxx and deducting the Shrinkage MMBtu's attributable to each of Producer's Xxxxx Shrinkage MMBtu's shall be the sum of the MMBtu's determined by multiplying the allocated gallons of each of Plant Product attributable to each of Producer's Xxxxx by the following conversion factors:

Plant Product	Conversion Factor (Btu/Gallon)
[ * ]

C. Plant Products Revenue attributable to each of Producer's Xxxxx shall be calculated by multiplying the percentage of each Plant Product allocable to each of Producer's Xxxxx by the total apportioned fractionated and non-fractionated Plant Products Sales Revenue received by Gatherer/Processor for the total of each Plant Product marketed by Gatherer/Processor or it designee during the applicable Accounting Period {FOB the Gas Plant and/or the Fractionator, as applicable), less transportation and fractionation fees with respect to fractionated volumes (currently [ * ][ * ] per gallon), subject to adjustment by Gatherer/Processor or its designee, as determined at the inlet to the Fractionator. Division of revenues from tile Plant Products shall be determined in accordance with the Gathering and Processing Fees provisions contained herein.

6 B

D. For purposes of determining the percentage of each plant Product allocable to each of Producer's Xxxxx, Gatherer/Processor shall multiply the volume in MCF's of Gas attributable to each of Producer's Xxxxx by the GPM (Gallons Per MCF) for each Plant Product contained in the well stream. Said GPM shall be determined by an Initial chromatograph analysis taken on spot Gas samples from each of Producer's Xxxxx subject to the measurement provisions of the Existing Agreements, The calculated value will be the Theoretical Plant Product Content for each Plant Product of Producer's Gas. Said Theoretical Plant Product Content for each Plant Product shall be divided by the Total Theoretical Plant Product Content for each Plant Product of all gas received by Gatherer/Processor to determine the percentage of Plant Product for each Plant Product attributable to each of Producer's Xxxxx.

E. Gatherer/Processor or its designee, in its sole discretion, shall determine whether or not to fractionate ail or any portion of the Plant Products based upon then current market conditions, and will market one hundred percent (100%) of the Plant Products, both fractionated and unfractionated, upon terms which, in Gatherer/Processor's or its Designee's sole judgement, are commercially reasonable. Upon request, Gatherer/Processor will furnish Producer on a monthly basis with reports containing volumes sold and prices applicable thereto. Upon execution of Gatherer/Processor's confidentiality agreement. Producer shall have the right at reasonable times during normal business hours to review the books and records of Gatherer/Processor pertaining to the sale of Plant Products, allocation of Residue Gas and revenues received therefrom.
