this ISS Rate schedule on any Day to deliver Gas in excess of the working gas

quantities then held in storage for Customer.

specified in Sections 4.1 through 4.4 of the General Terms and Conditions of

this Tariff.

(d) Customer shall not be permitted to increase its confirmed nomination

quantities under this ISS Rate Schedule, regardless of the quantities set

forth in Customer’s ISS Service Agreement, if such increase would degrade

service to a Customer with equal or higher priority as set forth in Section 4

of the General Terms and Conditions.

(e) Customer shall reimburse Caledonia for all other taxes associated with

the quantities held for Customer in storage under this ISS Rate Schedule.

Caledonia shall invoice Customer periodically for all taxes, if any,

attributable to the injection, storage or withdrawal of

Gas.

(f) Service rights under an ISS Service Agreement may not be released.

(g) Caledonia shall establish an account for each Customer using this

service which reflects the Interruptible Storage Balance. Whenever Caledonia

receives interruptible storage quantities from or delivers interruptible

storage quantities to a Customer, Caledonia will adjust the Customer’s

account, as appropriate, to reflect the new balance.

(h) All Gas injected into storage for Customer’s account under this ISS

Rate Schedule must be withdrawn by Customer’s contract termination date,

provided that such final contract termination date shall be extended one Day

for each Day, during the 30 Days preceding Customer’s final contract

termination date that Customer’s ISS withdrawals are interrupted by

Caledonia.

3. OVERRUN SERVICE

(a) Provided injections and withdrawals can be accepted without impeding

Caledonia’s ability to meet prior service obligations, a request by Customer

to make injections in excess of its ADIQ or withdrawals in excess of its ADWQ

may be submitted to Caledonia. In the event that Customer makes such request,

Caledonia will confirm the request to the extent that (1) additional

flexibility exists during the time period of the request, and (2) Caledonia,

using reasonable discretion, can operationally accommodate the request.

(b) Caledonia shall have the right to interrupt or not schedule all or

part of the overrun quantity nominated, as the operation of its facilities in

its reasonable judgment may require, subject to Sections 4.1 through 4.4 of

the General Terms and Conditions of this Tariff, in which event Caledonia

shall notify Customer.

4. RATES AND CHARGES

(a) The charges to be paid by Customer, as set forth in paragraph (b)

below, shall be mutually agreed to by Caledonia.
