GENERAL TERMS AND CONDITIONS (continued)

3. MEASUREMENT

3.1 Unit of Measurement and Metering Base. The volumetric measurement

base shall be one (1) cubic foot of Natural Gas at a pressure base

of fourteen and seventy-three hundredths (14.73) psia, a

temperature base of sixty degrees (60°F) Fahrenheit, and dry

(101.325 kPa, 15 degrees C, and dry). Except as otherwise

provided by law, the volume of Natural Gas delivered at the Point

of Receipt and at the Point of Delivery hereunder shall be

computed in accordance with the standards prescribed in Gas

Measurement Report No. 3 of the American Gas Association ("AGA"),

dated April 1955, as revised September 1969, and from time to time

amended, supplemented or superseded. All quantities of Natural

Gas given herein, unless otherwise stated, are in terms of the

unit of volume set forth above in this Section 3.1.

3.2 Atmospheric Pressure. For the purpose of measurement,

calculations and meter calibration, the average absolute

atmospheric (Barometric) pressure for each Point of Receipt and

Point of Delivery shall be as specified in an executed Service

Agreement irrespective of variations in natural atmospheric

pressure from time to time.

3.3 Temperature. The temperature of the Natural Gas shall be

determined at the point of measurement by means of recording

thermometers of standard manufacture acceptable to Transporter and

Shipper to be installed in accordance with the recommendations

contained in AGA Gas Measurement Report No. 3. The arithmetic

average of hourly temperatures of Day shall be used in computing

temperatures of the Natural Gas during each Day.
