The NNS agreement shall be for a mutually agreeable term.

4. PRIORITY OF SERVICE

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

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

5. RATE

Unless otherwise agreed upon by Gulf South and Customer, Customer shall

pay Gulf South each month under this NNS Rate Schedule (i) a

reservation charge based on Customer's Seasonal MDQ and (ii) a usage

charge for each unit of gas delivered. Customer shall also pay Gulf

South such other charges as set forth in this NNS Rate Schedule and the

General Terms and Conditions.

(a) Unless otherwise agreed upon by Gulf South and Customer, the

maximum monthly reservation charge shall be the maximum rate set

out on Sheet No. 24 of this Tariff multiplied by Customer's

Seasonal MDQ. The maximum monthly usage charge shall be the

maximum unit usage rate provided on Sheet No. 24 of the NNS Rate

Schedule multiplied by the quantity of gas delivered by Gulf

South under the NNS agreement during the billing month unless

otherwise agreed upon by Gulf South and Customer. Customer shall

also pay Gulf South all other charges as set forth on Sheet No.

24, as applicable.

(b) Unless otherwise agreed upon, Gulf South shall retain an in-kind

Fuel and Company-Used Gas allowance at all receipt points. The

percentage figure used for determining the amount of this

retention is set forth on Sheet No. 24. If Gulf South and

Customer mutually agree, Customer shall reimburse Gulf South in

cash for Fuel and Company-Used Gas instead of Gulf South

retaining gas in-kind. Gulf South may determine on a non-

discriminatory basis when it will offer customers the option to

reimburse Gulf South in cash for Fuel and Company-Used Gas.

Potential shippers may request to reimburse Gulf South in cash
