GENERAL TERMS AND CONDITIONS

7. Supply Deficiencies

If Transporter experiences a supply shortfall due to the under delivery of

supply by Shipper(s) to Transporter's mainline, then (a) if the deficient

source is known, Transporter will curtail the corresponding firm and/or

interruptible markets; or (b) if the deficient sources are undeterminable,

then Transporter will localize the smallest affected area and, at the

corresponding delivery point, will curtail interruptible service first in

reverse scheduling order and then firm services will be curtailed pro rata;

provided that verifiable receipt point volumes will not be subject to a

supply short fall curtailment. To the extent that information concerning the

deficient source is, or becomes, available, Transporter will provide such

information via PASSKEY to all curtailed Shippers.

8. Shipper Imbalances

8.1 Shipper's Duty to Control Imbalances: A Shipper receiving any

transportation service from Transporter will use, or will cause any

party receiving or delivering Shipper's gas to use, all reasonable

efforts to ensure that receipts and deliveries of gas equal the

Scheduled Quantities. A Shipper receiving service from Transporter at

a receipt and/or delivery point(s) not covered by a Balancing Agreement

shall also be responsible for controlling, and if necessary, adjusting

receipts and deliveries of gas to maintain a balance between such

receipts, deliveries, and Scheduled Quantities. To the extent a

Shipper is out of balance at a point not covered by a Balancing

Agreement, such Shipper will be subject to the daily and monthly

balancing provisions contained in the LMS-MA Rate Schedule for

delivery points or Transporter's LMS-PA Rate Schedule for receipt

points. Imbalances at such points will be allocated pro rata based on

Scheduled Quantities.

8.2 Outstanding Imbalances: Shippers shall remain responsible for

imbalances accrued before Implementation Date. Within thirty days of

the Implementation Date, Shipper shall be required to "cash out" any

outstanding imbalances effective on the day before the Implementation

Date in accordance with the procedures established in Transporter's

Tariff that was in effect on the day before the Implementation Date

unless the parties mutually agree otherwise.

8.3 Unauthorized Delivery Charge: Unauthorized deliveries are deliveries

of gas made to Transporter at the Receipt Point(s) or from Transporter

at Delivery Point(s) prior to submission of the Customer Nomination

Form and scheduling provided above.
