GENERAL TERMS AND CONDITIONS

----------------------------

1.7 DTH

The term "Dth" shall mean one million (1,000,000) Btus

and is equivalent to one (1) MMBtu.

1.8 ELECTRONIC DATA INTERCHANGE ("EDI")

The term "EDI" shall mean Electronic Data Interchange.

1.9 EQUIVALENT VOLUMES

"Equivalent Volumes" shall mean the sum of the volumes

of gas measured in Dth received by Trailblazer 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 Gas and Unaccounted

For Gas resulting from the operations of Trailblazer hereunder

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

in Section 6.7 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 five (5) 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,

Trailblazer shall formulate a thermal balance evaluating inputs to,

and deliveries from, the System at least once each month. The

difference between Btus delivered to Trailblazer for transportation

from all Shippers and Btus redelivered to all Shippers hereunder,

shall be deemed Fuel Gas and Unaccounted For Gas. Each Shipper

shall provide such Fuel Gas and Unaccounted For Gas pro rata to the

actual Btus of gas delivered by such Shipper to Trailblazer during

the period covered by the thermal balance; provided, however, that

each Shipper shall be responsible for Unauthorized Overrun Gas

delivered by Shipper to Trailblazer which is vented under Section

6.7; and provided further that Fuel Gas shall not exceed the actual

Fuel Gas as defined in Section 1.13 hereof. The formula used to

determine the delivery quantity shall be: [1 - (fuel percent/100)]

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

For purposes of this formula, the fuel percentage shall reflect

lost and unaccounted for gas.
