RATE SCHEDULE IT (Continued)

INTERRUPTIBLE TRANSPORTATION SERVICE

FORM OF SERVICE AGREEMENT

however, that any such discounted rate set forth above shall be between

the Maximum Rate and Minimum Rate applicable to the service provided

under this Agreement. In addition, the discount agreement may include a

provision that if one rate component which was at or below the

applicable Maximum Rate at the time the discount agreement was executed

subsequently exceeds the applicable Maximum Rate due to a change in

Trunkline's Maximum Rates so that such rate component must be adjusted

downward to equal the new applicable Maximum Rate, then other rate

components may be adjusted upward to achieve the agreed overall rate, so

long as none of the resulting rate components exceed the Maximum Rate

applicable to that rate component. Such changes to rate components

shall be applied prospectively, commencing with the date a Commission

order accepts revised tariff sheets. However, nothing contained herein

shall be construed to alter a refund obligation under applicable law for

any period during which rates which had been charged under a discount

agreement exceeded rates which ultimately are found to be just and

reasonable. Any discount shall be effective only on a prospective basis

and as specified in the written agreement between Trunkline and Shipper.

ARTICLE 4 - FUEL REIMBURSEMENT

In addition to collection of the rates and charges provided for in

Article 3, Trunkline shall retain, as Fuel Reimbursement, the percentage

of the Quantities received from Shipper hereunder, as provided pursuant

to Rate Schedule IT.

ARTICLE 5 - GENERAL TERMS AND CONDITIONS

This Agreement and all terms for service hereunder are subject to

the further provisions of Rate Schedule IT and the General Terms and

Conditions of Trunkline's Tariff, as such may be modified, supplemented,

superseded or replaced generally or as to the service hereunder.

Trunkline reserves the right from time to time to unilaterally file and

to make effective any such changes in the provisions of Rate Schedule IT

and the General Terms and Conditions, subject to the applicable

provisions of the Natural Gas Act and the Commission's Regulations

thereunder. Such Rate Schedule and General Terms and Conditions, as may

be changed from time to time, are by this reference incorporated in

their entirety into this Agreement and made an integral part hereof.
