GENERAL TERMS AND CONDITIONS

(continued)

(f) The specific gravity of the gas flowing through the meters shall be

determined by gas chromatographic analysis, recording gravitometer, or

continuous or spot sampling methods, unless otherwise mutually agreed upon by

Shipper and Pipeline. The arithmetic average of the specific gravity recorded

during each 24-hour Gas Day shall be used in computing gas quantities or other

periodic measurements within a shorter time frame or instantaneous specific

gravity measurements may be applied to metering instruments to provide the

quantity computation.

(g) When orifice meters are used, the computation of quantities of gas

delivered shall be in accordance with the recommendations as published by the

American Gas Association's Report No. 3, “Orifice Metering of Natural Gas and

Other Related Hydrocarbon Fluids” (ANSI/API 2530), and any subsequent

modifications or amendments thereof as may be mutually agreed upon by Shipper

and Pipeline.

(h) The Total Heating Value shall be measured, unless otherwise agreed by

the parties concerned, by methods in accordance with acceptable industry

practice, such as, but not limited to, recording calorimeter(s) or gas

chromatograph(s) located at appropriate points. The arithmetic average of the

heating value recorded each 24 hour Gas Day and as adjusted to conditions as

specified in Section 1 of the GT&Cs, or other periodic measurements within a

shorter time frame as Pipeline shall select, shall be used for computations.

(i) The deviation of the gas delivered hereunder from Boyle's and Charles'

Laws shall be determined in accordance with, but not limited to, the published

recommendations of the American Gas Association's Report No. 3, Revised 1994

and the American National Standards Institute as Pipeline deems to be in

accordance with accepted industry practice.
