FORM OF SERVICE AGREEMENT

ARTICLE 2 - TERM

This Agreement shall be effective from the date first stated

above. Trunkline shall provide interruptible Parking service for

Shipper pursuant to this Agreement from ____________________ until

_______________________, when this Agreement shall expire.

ARTICLE 3 - RATES AND CHARGES

For the services provided or contracted for hereunder, Shipper

agrees to pay Trunkline the then-effective, applicable rates and

charges under Trunkline's Rate Schedule GPS filed with the

Commission, as such rates and charges and Rate Schedule GPS may

hereafter be modified, supplemented, superseded, or replaced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 terms or rate levels under Rate Schedule GPS

and the applicability thereof, the General Terms and Conditions or

any other provisions of Trunkline's Tariff, subject to the applicable

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

thereunder.

From time to time Shipper and Trunkline may agree in writing on

a level of discount of the otherwise applicable rates and charges

hereunder pursuant to the effective applicable provisions of Rate

Schedule GPS and subject to the Regulations and Orders of the

Commission. For example, Shipper and Trunkline may agree that a

specified discounted rate shall apply: (a) only to certain

Quantities under this Agreement; (b) only if specified Quantity

levels are actually achieved or only with respect to Quantities below

a specified level; (c) only during specified time periods; or (d) in

a specified relationship to the Quantities actually parked (i.e.,

that the rates shall be adjusted in a specified relationship to

Quantities actually parked); provided, 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.

Any discount shall be effective only on a prospective basis and as

specified in the written agreement between Trunkline and Shipper.
