GENERAL TERMS AND CONDITIONS

(continued)

Report No. 3 ANSI/API 2530, as amended from

time to time, unless otherwise agreed.

(e) The Gross Heating Value shall be determined

by using a suitably located and reasonably

acceptable calorimeter or calculation from

fractional analysis by an acceptable

chromatograph, according to the methods

outlined in the AGA Measurement Committee

Report No. 5, as amended from time to time,

unless otherwise agreed. The Gross Heating

Value so determined shall be corrected from

the conditions of testing to that of the

actual condition of the Gas as delivered

(including the conversion from saturated to

dry conditions) expressed in Btu per cubic

foot and reported at a pressure base of 14.73

psia; provided, however, if the Gas as

delivered contains seven (7) pounds of water

or less per one million (1,000,000) cubic

feet, such Gas shall be assumed to have zero

(0) pounds of water per one million

(1,000,000) cubic feet (dry Gas).

2.4 Examination of Records. Upon request, the

measuring party shall make its measurement charts

and records available to the other party for

examination, the same to be returned within twenty

(20) Days; provided, however, that the measuring

party shall not be required to provide any such

records or charts more often than once in any

three (3) month period. Transporter's charts and

records for a given Service Month shall be

conclusively presumed correct if no written

objection thereto is served on Transporter in

accordance with the provision of Section 14.4

below. Records will be retained for a period of

two Years.
