GENERAL TERMS AND CONDITIONS

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

1.8 DTH

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

and is equivalent to one (1) MMBtu.

1.9 ELECTRONIC DATA INTERCHANGE ("EDI")

The term "EDI" shall mean Electronic Data Interchange.

1.10 EQUIVALENT VOLUMES

"Equivalent Volumes" shall mean the sum of the volumes

of gas measured in Dth received by Canyon 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 Canyon hereunder during the same

period of time, and (ii) any gas vented as provided in Section 5.6

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, Canyon

shall formulate a thermal balance evaluating inputs to, and

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

between Btus delivered to Canyon 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 Canyon during the period covered by

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

responsible for Unauthorized Overrun Gas delivered by Shipper to

Canyon which is vented under Section 5.6; and provided further that

Fuel Gas shall not exceed the actual Fuel Gas as defined in Section

1.13 hereof. Notwithstanding the foregoing, the thermal balance

shall be adjusted to eliminate the effect of changes in line pack

that month, if any. 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.
