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 Horizon 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 Horizon

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

as provided in Section 3.7 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,

Horizon shall formulate a thermal balance evaluating inputs to,

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

difference between Btus delivered to Horizon 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 Horizon during

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

each Shipper shall be responsible for Unauthorized Overrun Gas

delivered by Shipper to Horizon which is vented under Section 3.6;

and provided further that Fuel Gas shall not exceed the actual

Fuel Gas as defined in Section 1.11 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.
