GENERAL TERMS AND CONDITIONS

14. ALLOCATION AND IMBALANCES (Cont'd.)

of this Subsection (c), an "Annual Billing Period" shall be the

twelve month period commencing each April and ending the

following March 31. Subsequent to the end of each Annual

Billing Period, Transporter shall compare (i) the sum of (A)

the revenues received by Transporter under the cash-out

procedures and (B) one-half (1/2) of Transportation Balancing

Fees collected by Transporter from shippers who have elected

(or have been deemed to elect) to resolve imbalances via cash-

out in accordance with Section 14.10 hereof, with (ii) the

costs incurred by Transporter under such cash-out procedures,

including the costs of purchasing gas to replace any quantities

of gas conveyed in cashing out negative imbalances which are

not offset by gas obtained in cashing out positive imbalances

or Unauthorized Gas, as defined below. If the revenues

received exceed the costs incurred, then Transporter shall

credit, within 60 days of the end of the Annual Billing Period,

the net overrecoveries to EFT, FT, FST and FT-S Shippers on a

pro rata basis in accordance with the transportation volumes

Transporter has delivered to each such Shipper during the

Annual Billing Period. Such refund may be accomplished by a

credit payment or a credit against any amounts owed by Shipper

to Transporter. If the revenues received are less than the

costs incurred, then Transporter shall carry forward the net

underrecoveries to the subsequent Annual Billing Period and may

offset such net underrecoveries against any future net

overrecoveries that may occur in a subsequent Annual Billing

Period. For purposes of this section, the term "Unauthorized

Gas" shall mean, with regard to a given Annual Billing Period,

the quantity of gas retained as unauthorized tenders in

accordance with Section 15.2 of these General Terms and

Conditions.
