GENERAL TERMS AND CONDITIONS

(continued)

2. MEASUREMENT (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.

2.5 Closing of Measurement. Transporter will close measurement no

later than five (5) Business Days after the end of the applicable
