GENERAL TERMS AND CONDITIONS

(Continued)

4. MEASUREMENT OF GAS (Continued)

4.4 Temperature and Specific Gravity. The following measurement

factors shall be given due consideration.

(a) The temperature of the natural gas flowing through each meter

shall be an assumed temperature arrived at by agreement or the

actual measured temperature.

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

party operating the meter by calculation, adjusted for any

difference between the specific gravity in the ideal state and in

the real state in accordance with published procedures accepted by

the American Gas Association.

4.5 Notice of Equipment Tests. Unless otherwise agreed to by the

parties, the party operating the measurement facilities shall give

notice to the other party of the time and location of all tests of gas

delivered hereunder or of any equipment used in measuring or determining

the nature or quality of such gas, in order that such other party may

conveniently have its representative present. Should the non-operating

party reasonably not be satisfied with any such test, it shall so notify

the operating party and the operating party shall perform such retests

as may be necessary to assure an accurate test.

4.6 Meter Testing. The accuracy of measurement equipment shall be

verified at reasonable intervals by the party operating such equipment,

and if requested, in the presence of representatives of the other party,

unless otherwise agreed to by the parties. If either party notifies the

other that it desires a special test of any measurement equipment, the

operating party shall cooperate to secure an immediate verification of

the accuracy of such measurement equipment and joint observation of any

adjustments. The payment for all such tests shall be borne by the

party requesting the test, unless otherwise agreed to by the parties.

4.7 Check Meters and Non-Interference. Either party may install and

operate check meters at its option and expense to check the other

party's primary measurement equipment, but measurement of gas shall be

by the measurement equipment of the parties identified in Section 4.3.

Such check meters shall be installed so as not to interfere with the

operation of the primary measurement equipment of such parties. The

parties shall exercise care in the installation, maintenance and

operation of check measuring, pressure regulating equipment or gas

compressors so as to prevent any inaccuracy in the determination of the

quantity or quality of gas being measured. If unacceptable square root

error or gauge line error shifts occur, the installation of pulsation
