GENERAL TERMS AND CONDITIONS

(Continued)

2.4 Transporter and Shipper may agree, or governmental authorities may require, that

the gas be odorized by use of a malodorant agent of such character as to indicate

by a distinctive odor the presence of gas.

2.5 Transporter may refuse to accept gas or may impose additional gas quality speci-

fications and restrictions if transporter, in its reasonable judgment, determines

that harm to transporter’s facilities or operations could reasonably be expected

to occur if it receives gas that fails to meet such additional specifications and

restrictions.

3. MEASUREMENT

3.1. The volume and the total heating value of Gas received and delivered by Transpor-

ter shall be determined as follows:

3.1.1. The unit of Gas received and delivered by Transporter shall be an MMBtu.

3.1.2. The unit of volume, for the purpose of measurement, shall be one cubic

foot of natural gas at a pressure base of fourteen and seventy-three one-

hundredths (14.73) pounds per square inch absolute, a temperature base of

sixty degrees (60°) Fahrenheit (519.67 o R Absolute), and without adjust-

ment for water vapor content.

3.1.3 Measurement Unit. The Measurement Unit shall be one MMBtu of natural gas

and shall be calculated by multiplying the volume delivered in Mcf by a

fraction, the numerator of which is the Heating Value and the denominator

of which is 1,000.

3.2. The factors required to determine the volume of Gas received, such as pressure,

temperature, specific gravity, supercompressibility and deviations from Boyle’s

Law, shall be calculated in accordance with the applicable American Gas Associa-

tion Bulletin and any modifications and amendments thereof, and applied in a prac-

tical manner.
