(a) Subject to the terms of the Agreement, Transporter reserves the

right to prescribe and/or to adjust at any time any of the

rates applicable to any individual Shipper without adjusting

any other rates for that or another Shipper; provided, however,

that such adjusted rate(s) shall not exceed the applicable

maximum recourse rate(s) nor shall they be less than the

applicable minimum recourse rate(s), set forth from time to

time on the Statement of Rates of this Tariff.

(b) A discount from the maximum rate shall be for a specific term.

Unless otherwise agreed, at the expiration of the Term of Rate

specified in Exhibit "A" of the Agreement, the rate for Storage

Service shall revert to the maximum allowable recourse rate

under this Rate Schedule. Such minimum and maximum recourse

rate shall not apply to service provided pursuant to Section

4.17 of the General Terms and Conditions of this Tariff.

(b) If a new currently effective Average Thermal Content of Gas in

Storage is posted on Transporter's electronic bulletin board as

provided in Section 1.2 of the General Terms and Conditions of

this Tariff it shall become effective on the first Day of the

Month following the Month the posting occurred. Such adjustment

shall be made by multiplying the fraction [(1,000) over (new

currently effective ATC in Btu)] times Shipper's rates as

listed in the Agreement.
