4. IMBALANCE NETTING AND TRADING (Continued)

End-of-Month Trading

Balancing Parties and Aggregators under Rate Schedule SA will also be allowed to

trade offsetting imbalances in the month following the month during which the

imbalance occurred; provided that the Party notifies Company of the identities of

the Parties agreeing to the trade, and the gas quantities to be traded, no later

than seventeen Business Days after the end of the month during which the

imbalances occurred. For receipt-to-delivery imbalance trades after the month

during which the imbalances occurred, the Parties agreeing to the trade must

notify Company of the Party responsible for the transportation from point to

point. If the Parties do not notify Company of the Party responsible for

transportation, Company will hold the Party who traded the imbalance due Company

responsible for the applicable transportation charges. To facilitate end-of-

month imbalance trading, Company will provide for Parties to post their

imbalances, and any information relevant to the trading thereof, on the System.

For mid-month and end-of-month trading, transportation charges for receipt-to-

delivery imbalance trades will be based on the maximum applicable authorized

overrun rate associated with Company's Rate Schedule FT-A or FT-C.

When a netting and trading transaction results in an overpayment of

transportation charges, Company shall reimburse the affected Shipper the excess

transportation charges in the subsequent billing cycle.
