GENERAL TERMS AND CONDITIONS

conform to any of the specifications set forth in Sections 9.1, 9.2

or 9.3 relieve Shipper of Shipper's obligation to pay Transportation

Reservation Charges, if applicable. In no event shall the failure

of any gas made available to or on behalf of Shipper at any Delivery

Point(s) to conform to any of the specifications set forth in

Sections 9.1, 9.2 or 9.3 relieve Shipper of Shipper's obligation to

pay the Transportation Commodity Charges and, if applicable,

Transportation Reservation Charges.

10. MEASUREMENT

The volume and the total heating value of the gas delivered to

Transporter at the Receipt Point(s) and made available to or on behalf of

Shipper at the Delivery Point(s) shall be determined as follows:

10.1 Unit of Measurement. The unit of gas, for the purpose of

measurement, shall be one Mcf.

10.2 Heating Value Per Cubic Foot. The total heating value of the

gas per cubic foot shall be determined for any month by taking the

weighted average of the heating values as recorded each day by a

calorimeter or as determined by chromatographic analysis of a sample

of gas collected daily during the month, or any other method mutually

agreed upon by Shipper and Transporter.

10.3 Determination of Dekatherms Delivered. The dekatherms delivered

shall be determined by multiplying the Mcf delivered by the ratio of

the Btu per cubic foot delivered to 1,000. For purposes of this

determination, the specific gravity and heating value shall be

determined at approximately the same time.

10.4 Determination of Temperature. The temperature of the gas passing

through each meter shall be determined for any day by the continuous

use of a recording thermometer so installed that it may properly

record the temperature of the gas flowing through each meter. The

arithmetical average of the temperature recorded each day shall be

used in computing gas quantities.

10.5 Specific Gravity. The specific gravity of the gas shall be

determined by the use of a recording gravitometer, which shall be

checked at least once each month, or any other method mutually agreed

upon by Shipper and Transporter.
