GENERAL TERMS AND CONDITIONS

1. DEFINITIONS (Contd.)

1.16 Equivalent Volumes. The sum of the volumes of Gas measured in

Dth received by Transporter for the account of Shipper at the

Receipt Points during any given period of time: (a) reduced by

(i) Shipper's pro rata share of Fuel and Lost and Unaccounted-

for Gas resulting from the operations of Transporter hereunder

during the same period of time, and (ii) any Gas vented as

provided in Section 3.6B hereof during the same period of time;

and (b) adjusted for any variations in Btu content, as

corrected for any water vapor in excess of six (6) pounds per

million (1,000,000) cubic feet of Gas, it being the intent of

the parties that the volumes of Gas delivered hereunder at the

Delivery Point after transportation be the thermal equivalent

of the volumes of Gas delivered at the Receipt Point for

transportation, after reduction, correction and adjustment as

provided above.

In determining Equivalent Volumes for redelivery, Transporter

shall formulate a thermal balance evaluating inputs to, and

deliveries from, the System at least once each Month. The

difference between Btus delivered to Transporter for

transportation from all Shippers and Btus redelivered to all

Shippers hereunder, shall be deemed Fuel and Lost and Unaccounted-

for Gas. Each Shipper shall provide such Fuel and Lost and

Unaccounted-for Gas pro rata to the actual Btus of Gas delivered

by such Shipper to Transporter during the period covered by the

thermal balance; provided, however, that each Shipper shall be

responsible for Unauthorized Overrun Gas delivered by Shipper to

Transporter which is vented under Section 3.6B; and provided

further that Fuel shall not exceed the actual Fuel as defined in

Section 1 of these General Terms and Conditions. The formula used

to determine the delivery quantity shall be: {(1 - FL&U%) / 100}

multiplied by the receipt quantity (rounded to the nearest Dth).
