GENERAL TERMS AND CONDITIONS

19. MEASUREMENTS AND TESTS FOR DELIVERY OF NATURAL GAS (Continued)

(f) Specific Gravity. The specific gravity (relative density) of the Natural Gas shall be

determined by gravitometric, chromatographic, or other generally accepted analytical

method at Operator's option:

(1) where Electronic Measurement equipment is provided,

(i) by contemporaneous application of continuous instantaneous specific

gravity measurements, or by contemporaneous application of arithmetic or

other average of the specific gravity for the time during which gas was

flowing,

(ii) by prospective application of the arithmetic or other average of the

specific gravity record, or

(iii) by prospective application of the results of analyses of samples of the

gas;

(2) where Electronic Measurement equipment is not provided,

(i) by contemporaneous application of the arithmetic or other average of the

hourly or daily continuous specific gravity record,

(ii) by prospective application of the results of analyses of samples of the

gas; or

(3) by any other method or methods mutually agreed upon by Operator and Buyer.

(g) Heating Value. The heating value of the Natural Gas shall be determined by

calorimetric, chromatographic, or other generally accepted analytical method at

Operator's option:

(1) where Electronic Measurement equipment is provided,

(i) by contemporaneous application of continuous instantaneous heating value

measurements, or by contemporaneous application of the arithmetic or other

average of the heating value for the time during which gas was flowing,
