GENERAL TERMS AND CONDITIONS (cont'd)

13. RESOLUTION OF IMBALANCES

13.1 Responsibility to Control Imbalances:

(a) A Shipper receiving any transportation service from

Transporter will use, or will cause any party delivering or

receiving Shipper's gas to use all reasonable efforts to ensure

that receipt and deliveries of gas are equal to Shipper's

scheduled quantities at the Receipt and Delivery Point(s)

pursuant to Shipper's Transportation Service Agreement(s).

(b) Transporter will use all reasonable efforts to ensure that

delivery of gas pursuant to its Transportation Service

Agreement(s) is equal to Shipper's scheduled quantities at the

Delivery Point(s).

(c) To aid Shippers in managing the magnitude of their

individual Net Monthly Imbalance, Transporter will

post on Transporter's Interactive Internet Website

daily by Transportation Service Agreement an

Estimated Net Imbalance calculated with the data

available then to date.

13.2 Resolution of Monthly Imbalances:

(a) No imbalance charges should be imposed when a

prior period adjustment applied to the current

period causes or increases a current monthly

imbalance charge.

(b) All imbalances accrued by Shipper under its

Transportation Service Agreements shall be

resolved on a monthly basis pursuant to the

provisions herein. Transporter will calculate,

for each Transportation Service Agreement, the

imbalance which exists between (i) the summation

of the quantities of gas allocated each day to

Shipper for its accounts at the Delivery Point(s)

and (ii) the summation of the quantities of gas

allocated each day to Shipper for its accounts at

the Receipt Point(s) during the month. All such

imbalances ("overdeliveries" if positive value and

"underdeliveries" if negative value) accrued by

Shipper under each of its Transportation Service

Agreements will be combined to derive a "Net

Monthly Imbalance" (in Dth).
