GENERAL TERMS AND CONDITIONS

4.3 Measurement for Delivery of Vaporized LNG:

(a) Unit of Volume:

The unit of volume shall be a cubic foot.

(b) Measurement of Volume:

(i) When gas is delivered at a pressure different from 14.73 psia, then for the

purpose of measurement hereunder, such volumes of gas shall be corrected to a

pressure of 14.73 psia. It is assumed that the atmospheric pressure is 14.4

pounds per square inch or such other pressure as agreed upon by Southern LNG

and Customer. The measurement of gas volumes shall be adjusted for deviation

from Boyle's Law in accordance with generally accepted engineering practice;

provided, however, that where gas is delivered through positive displacement

meters at a pressure not in excess of 20 psig, the gas may be assumed to obey

Boyle's Law.

(ii) Where orifice meters are used, volumes delivered shall be computed in

accordance with formulae, tables, and methods prescribed in Orifice Metering

of Natural Gas and Other Related Hydrocarbon Fluids, AGA Report No. 3 --

ANSI/API 2530, as revised September 1985, and as such report may hereafter be

further revised. Exact measurements of inside diameters of meter tubes shall

be obtained by means of a micrometer to the nearest one-thousandth inch.

Volumes shall be corrected for flowing temperature and specific gravity in

accordance with the provisions of paragraphs (iii) and (iv) below.
