GENERAL TERMS AND CONDITIONS

(Continued)

4.2 (Continued)

CIPCO shall be obligated to deliver gas at

pressures up to, but not in excess of, the maximum

delivery pressure obligation specified in such

Service Agreement. CIPCO shall not be obligated to

deliver gas at any time at a pressure in excess of

the Maximum Allowable Operating pressure for CIPCO's

facilities at such Delivery Point(s). In addition,

Customer and CIPCO may specify in such Service

Agreement a minimum delivery pressure obligation at

any primary or secondary Delivery Point(s), and CIPCO

shall not be obligated to reduce the pressures in its

facilities at such Delivery Point(s) below such

minimum delivery pressure obligation.

5. MEASUREMENT

5.1 Determination of Quantity

The quantity of gas received and delivered by

CIPCO on behalf of Customer hereunder shall be

measured according to Boyle's and Charles' Laws for

the measurement of gas under varying pressures and

temperatures with deviations therefrom as provided in

paragraph (i) below and shall be determined as

follows:

(a) The unit of measurement for the

purpose of service under any of CIPCO's Rate

Schedules shall be one (1) dekatherm (Dth),

consisting of one million (1,000,000) British

Thermal Units. The number of dekatherms

delivered shall be determined by multiplying the

number of cubic feet of gas received or

delivered, measured on the measurement basis

hereinafter specified, by the total heating

value of such gas, in British Thermal Units per

cubic foot, as defined in Section 2 above, and

by dividing the product by 1 million

(1,000,000).

(b) The unit of quantity for the purpose

of measurement shall be one (1) cubic foot of

gas at a temperature of 60o Fahrenheit and an

absolute pressure of 14.73 pounds per square

inch.
