redelivery by Gulf South to Customer at the point of withdrawal.

With Gulf South's prior consent, Customer may withdraw a quantity

of gas in excess of Customer's inventory if in Gulf South's sole

judgment such excess withdrawals do not adversely impact Gulf

or would not create a diversion as defined by Section 10.6 of the

General Terms and Conditions of this Tariff.

(d) Customer has the right to transfer working gas in storage under

this ISS Rate Schedule up to the amount then in inventory, with

no injection or withdrawal charge, to another Customer's

inventory at the same storage facility provided that such

Customer has an effective FSS-B, FSS-M, ISS, or NNS agreement not

to exceed the other Customer's MSQ. Both contracts affected by

the working gas in storage transfer must be effective during the

production month that the transfer is completed.

Priority of service shall be determined in accordance with Sections 7,

10, 11, 12 and 13 of the General Terms and Conditions.

4. TERM

that a Customer has gas remaining in storage at the end of its contract

term, the remaining storage balance shall be purchased by Gulf South

at 50% of the Index "Buy" Price as defined in Section 20.1(B), unless

Gulf South and Customer mutually agree otherwise. Money paid or

received when said gas is purchased or sold shall be treated under Gulf
