GENERAL TRANSPORTATION TERMS AND CONDITIONS

(Continued)

9. FORCE MAJEURE (Continued)

Such causes or contingencies affecting the performance under the

executed Transportation Agreement by either Transporter or Shipper,

however, shall not relieve it of liability in the event of its

concurring negligence or in the event of its failure to use due

diligence to remedy the situation and to remove the cause in an adequate

manner and with all reasonable dispatch, nor shall such causes or

contingencies affecting such performance relieve either party from its

obligations to make payments of amounts then due in respect of gas

theretofore delivered.

10. INTERRUPTIONS OF SERVICE

10.1 Tests and Repairs. Transporter shall have the right, without

liability to Shipper, to interrupt the transportation of gas for Shipper

when necessary to test, alter, modify, enlarge or repair any facility or

property comprising a part of, or appurtenant to, Transporter's pipeline

system, or otherwise related to the operation thereof. Transporter

shall endeavor to cause a minimum of inconvenience to Shipper because of

such interruptions.

10.2 Operational Control. Transporter shall retain full operational

control of its pipeline system and shall at all times be entitled to

schedule deliveries and to operate its pipeline system in a manner

which, in Transporter's sole opinion, is consistent with the obligations

and operating conditions as they may exist from time to time on

Transporter's system, or which will allow Transporter to optimize the

receipt and/or utilization of its gas supplies and for its transmission

system now and in the future. Nothing in this Agreement shall be deemed

to impinge on such operating flexibility.

11. TRANSPORTATION AGREEMENT AND SERVICE CONDITIONS

11.1 Form of Agreement. Transporter and Shipper shall execute a

Transportation Agreement covering the transportation service

contemplated. The executed Transportation Agreement, together with the

General Transportation Terms and Conditions and applicable rate

schedules shall constitute the entire agreement between the parties for

gas transportation service provided therein and shall be modified only

in writing.
