GENERAL TERMS AND CONDITIONS

(Continued)

14. DETERMINATION OF DELIVERIES AND IMBALANCES (Continued)

force majeure conditions to accommodate Shipper's make-up nominations,

provided such nominations are from Shipper's primary Receipt Points. A

Shipper may eliminate Shipper Imbalances by scheduling imbalance gas in

accordance with the procedures outlined in Section 14 hereof.

14.8 Shipper Imbalance Netting. Upon Shipper's request, Transporter

will net Shipper Imbalances with Shipper Imbalances, and Shipper

Imbalances with Receiving Party Imbalances, between its Service

Agreements, provided that Shipper will reimburse Transporter for any

difference in transportation revenues that may result from such netting.

In any case, a Shipper netting a positive Shipper Imbalance (Transporter

owes Shipper) for a negative Receiving Party Imbalance (Receiving Party

owes Transporter) will be subject to volumetric transportation charges

for the delivery of that imbalance quantity. Netting between a Shipper's

Service Agreements, when offsetting a Receiving Party Imbalance with a

Shipper Imbalance, will be limited to a maximum quantity equal to the

smallest imbalance under the agreements being netted. Shipper Imbalances

may also be eliminated by trading imbalances with third parties as set

forth in Section 14.9.

14.9 Shipper/Receiving Party Imbalance Trading. A Shipper or Receiving

Party may eliminate imbalances by trading imbalances between Service

Agreements with third parties provided that Transporter will be

reimbursed for any difference in transportation revenues that may result

from such trading. In any case, a Shipper trading a positive Shipper

Imbalance (Transporter owes Shipper) for a negative Receiving Party

Imbalance (Receiving Party owes Transporter) will be subject to

transportation charges for the delivery of that imbalance quantity.

Trading between Service Agreements of third parties, when a Receiving

Party Imbalance is traded with a Shipper Imbalance or another Receiving

Party Imbalance, will be limited to a maximum quantity equal to the

smallest imbalance under the agreements being traded.

(a) All imbalance trading shall be conducted via telecopy/facsimile

transmissions. If Shipper/Receiving Party desires to trade

imbalances, Shipper/Receiving Party must consent to Transporter's

release of necessary information regarding its imbalance.

(b) Shippers are responsible for making whatever arrangements

they deem necessary to finalize and document the imbalance trade

among themselves.
