designated by the specifications referenced in

Section 2.1, as determined in accordance with

Section 3.7, the gross calorific heating value

will be adjusted to reflect the actual water

vapor content of the gas accordingly for billing

purposes.

In the event gas is received into Transporter's

pipeline system from an interconnect other than

the Receipt Point defined herein, Shipper may

request and, upon such request, Transporter shall

be required to install an automatic sampling

device to measure the hydrogen sulfide levels in

the gas. The hydrogen sulfide content of the gas

shall be determined in accordance with the Gas

Processors Association Standard for such

determination then in effect, and if there is no

such standard in effect, by a method generally

used and accepted in the industry and agreeable

total number of MMBtus delivered shall be

determined by multiplying the delivered gross

calorific heating value, as determined in Section

3.8, by the total volume of gas as determined in

Section 3.1. If the total MMBtu results obtained

by use of Transporter's equipment, as specified

in Section 3.1 and 3.8, differ by one percent or

indicate that Transporter's measurement equipment

is not within the tolerance levels set forth in

Section 3.5 and that Shipper's measurement

equipment is within the tolerance levels set

forth in Section 3.5, then Shipper's measurement

equipment shall be used. If such calibrations

indicate that neither parties' measurement

equipment is within the tolerance levels set

forth in Section 3.5, then the provisions of
