GENERAL TERMS AND CONDITIONS (continued)

III. MEASUREMENT AND SCHEDULING OF RECEIPTS AND DELIVERIES

1. Determination of volume: The volume of gas received and delivered by

Transporter shall be determined as follows:

(a) Unit of Measurement: The service unit of gas scheduled, received, or

delivered by Transporter shall be a dekatherm. Daily quantities

shall be prorated uniformly over periods of hours for scheduling of

service changes during the day.

(b) Dekatherms shall be determined by multiplying the Mcf volume by the

ratio of the heating value per cubic foot to 1,000.

(c) The unit of volume, for the purpose of measurement, shall be defined

as one cubic foot (1cf) of gas at a temperature of sixty degrees

Fahrenheit (60oF), and at a pressure of thirty-three hundredths

pounds per square inch (.33 PSI) above an assumed atmospheric

pressure of fourteen and four tenths pounds per square inch (14.4

PSI) resulting in a pressure of fourteen and seventy-three hundredths

pounds per square inch (14.73 PSI) absolute pressure. One thousand

(1,000) cubic feet shall be denoted as 1 Mcf.

(d) The closing of measurement shall be no later than the fifth (5th)

business day after the close of the production month.

2. Determination of Total Heating Value: The total heating value of gas

received and delivered by Transporter shall be determined as follows:

(a) The total heating value of the gas per cubic foot shall be determined

by taking the average of the heating values as determined each day by

a chromatograph or the chromatographic analysis of a sample of gas,

or any other method mutually agreed upon. The average (flow

weighted) heating value of the gas per cubic foot (Btu/cf) for a unit

of time shall be determined by the total dekatherms divided by the

total Mcf volume multiplied by 1000.

(b) The temperature of the gas passing through the meters shall be

determined continuously by a recording thermometer so installed that

it may properly record the temperature of the gas flowing through the

meters. Arithmetic averages of the temperature recorded each day

shall be used in computing the Mcf of gas.

(c) The specific gravity of the gas delivered shall be determined by the

use of chromatographic analysis or any other method mutually agreed

upon. Determination of the specific gravity and heating value per

cubic foot (Btu/cf) shall be determined at approximately the same

time or from the same analyzed gas sample.
