9. RESOLUTION OF IMBALANCES

9.1 RESPONSIBILITY FOR BALANCING - In addition to delivering and receiving

volumes of Gas in conformance with nominations, Shippers are responsible

for conforming their takes at Delivery Points with their deliveries to

Transporter at Receipt Points each Day. Transporter has no obligation

to deliver for the account of Shipper greater quantities of Gas than

Transporter has received for the account of Shipper or to accept for the

account of Shipper greater quantities of Gas than are being delivered

for the account of Shipper on any Day.

9.2 MONTHLY IMBALANCES - At the end of each Month, to the extent receipts

(after appropriate reductions for Fuel, Lost and Unaccounted for Gas) do

not equal deliveries under an Effective Service Agreement on a Dt basis,

the procedures described in Sections 9.3 and 9.4 will apply.

9.3 IMBALANCE TRADING - Following the issuance of actual imbalance data for

a Month, a Shipper or its agent may trade imbalances with other

Shippers, subject to the conditions of this section. A Shipper that

desires to trade imbalances with other Shippers may post a notice on

Transporter's internet web site by requesting such posting by 9:00 a.m.

on the calendar Day following the Day on which the actual imbalance data

is issued. Shippers must notify Transporter of any trades Shipper has

made with other Shippers by 5:00 p.m. on that Day. Transporter will

recognize a trade of imbalances only if each party to the trade timely

notifies Transporter of the trade, the identity of the Shipper(s) with

whom the trade was made, the relevant Transporter Service Agreement

numbers for each Shipper involved in the trade, the volumes traded, and

Transporter is able to confirm that the information results in a match

and the trade is permitted hereunder. Trading will be limited to

imbalances occurring between the same receipt and delivery points.

Transporter will cash out any imbalances that have not been traded by

the time specified for notifying Transporter of such trading within two

Business Days thereafter, as provided in section 9.4.
