GENERAL TERMS AND CONDITIONS

(Continued)

10.2 (continued)

(e) Imbalance Trades. The term "Imbalance Trade" shall mean the

reallocation of imbalances from one Shipper to another Shipper

in order to reduce the imbalances of both Shippers. Transporter

shall effect an election to Trade imbalances incurred during a

Month as posted and verified electronically.

(i) A Shipper, acting without the assistance of Transporter,

may negotiate an Imbalance Trade arrangement with

another Shipper.

(ii) A Shipper may post on Transporter's electronic bulletin

board the Shipper's availability to Trade imbalances. A

Trade posting shall include the quantity to be Traded,

the Shippers' contact names and phone numbers and any

special conditions. Such posting may be made through the

last Day of the Month following the Month of Gas flow.

(iii) Shippers shall negotiate the terms of any Trades among

themselves.

(iv) Shippers Trading imbalances must electronically notify

Transporter of their Trade no later than the last

Business Day of the Month following the Month in which

the imbalance to be Traded was created.

(v) Only Trades which have the effect of reducing a

Shipper's imbalances are permitted (i.e., the maximum

quantity which may be Traded is the smaller of the

excess or shortfall under the Shipper's Agreements

affected by the Trade).

(vi) Transporter shall permit Trade arrangements at no

additional cost to the Shippers.

(vii) After completion of all Trade transactions, Transporter

shall apply the Traded imbalance quantities to Shipper's

original Agreement-level imbalances. Agreements with the

largest percentage imbalances (see Section 10.5 below

for percentage calculation) shall be credited with Trade

quantities first. Trade quantities shall be applied to

Agreement-level imbalances until the Trade quantities

have been fully allocated.

(f) A Shipper may only apply one of the adjustment procedures to

any individual unit of imbalance (i.e., the same quantity

cannot be scheduled for Trade and imbalance payback, however,

portions of an imbalance may be scheduled for different

adjustment procedures).
