General Terms and Conditions

9.4 Failure to Conform to Specifications. If the Gas offered for delivery to

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

Shipper at the Delivery Point(s) by Transporter shall fail at any time to

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

9.3 of the General Terms and Conditions of this Tariff, then the party

receiving such Gas (the "receiving party") shall notify the other party

(the "tendering party”) of such deficiency and thereupon the receiving

party may at its option refuse to accept such Gas pending correction by

the tendering party. Upon the tendering party's failure promptly to

remedy any deficiency the receiving party may accept such Gas and may make

changes necessary to bring such Gas into conformity with such

specifications, and the tendering party shall reimburse the receiving

party for any reasonable expense incurred by it in effecting such changes.

In no event shall the failure of any Gas offered for delivery to

Transporter by Shipper or for Shipper's account to conform to any of the

specifications set forth in Sections 9.1, 9.2 or 9.3 of the General Terms

and Conditions of this Tariff 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 of the General Terms and Conditions of this

Tariff 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.

10.6 Deviation From Boyle's Law. The deviation of the Natural Gas from Boyle's

Law shall be determined by the use of the table of formulas published by

the American Gas Association Par Research Project NX-19 corrected for

carbon dioxide and nitrogen, or any superseding applicable tables

published by the American Gas Association. Determinations of the molecular

percentage of N2 and C02 in the Gas shall be made within 30 days after

commencement of deliveries and at least quarterly thereafter. The

molecular percentage of N2 and C02 thus determined will be used to

determine the supercompressibility factors during the ensuing period, with

corrections for specific gravity, temperature and pressure.
