GENERAL TERMS AND CONDITIONS

14. MEASUREMENT

14.1 Quantities delivered hereunder at each Point of Receipt and Point

of Delivery will be determined by either Trunkline or Shipper,

whichever is responsible for measurement at such point as listed

on Exhibit A of the Service Agreement. The heating value,

specific gravity and supercompressibility (Mol percent of nitrogen

and carbon dioxide) values of the Gas shall be determined at the

beginning of receipt and delivery and annually thereafter, or at

more frequent intervals as may be found necessary in practice.

Water content shall be determined at intervals as found necessary

in practice.

14.2 Such measurement, both volumetric and thermal, shall be at a

temperature of 60ø Fahrenheit and at a pressure of 14.73 psia dry,

and on the basis of the methods prescribed and published by the

American Gas Association in conjunction with the ANSI/API 2530

Report as now and any subsequent amendments thereof accepted and

agreed upon between the parties if orifice meters are used, and in

accordance with generally accepted industry practices, as mutually

agreed upon, if positive displacement or turbine meters are used.

The Btu content shall be determined by taking the arithmetic

average of the heating value as recorded by recording calorimeter

or other method of determination generally accepted in the

industry. Flowing temperature shall be determined by a recording

thermometer or EGM.

14.3 All measuring stations shall be mutually acceptable to Trunkline

and Shipper and installed and operated to conform to recognized

industry standards, using flange connections and, where necessary,

pulsation dampening equipment. Auxiliary equipment shall be

installed so as not to interfere with the measurement of either

party.

14.4 Either Trunkline or Shipper may witness the installation or

maintenance of others' equipment. Neither Trunkline nor Shipper

shall be required to verify accuracy more often than once during

any thirty (30) day period. If, upon test, accuracy is found to

be within two percent (2%) by volume (chromatograph/calorimeter

within 0.5%), such equipment shall be assumed to be accurate. Any

error exceeding these percentages will require correction to zero

error of previous recordings back to the date error began. If the

beginning date of error is unknown, correction shall extend to

one-half the time since the last test, not to exceed sixteen (16)

days.
