services performed under this Agreement must be performed in conjunction with the

transportation of such gas stream. In the event Company finds it necessary to allocate

capacity in the facilities utilized for Shipper's service hereunder, the allocation of

capacity to Shipper's Agreement shall be dependent on the allocation of capacity Company

makes, pursuant to the terms of its FERC Gas Tariff, to the transportation agreement(s)

under which the gas stream associated with Shipper's liquefiables is being transported.

Company shall not change the quantities of gas it will transport hereunder during any

day of transportation except upon four (4) hours' prior notice to Shipper.

2.2 At any time the processing plant to which Company is transporting liquefiables

on Shipper's behalf is shut down, transportation under this Agreement shall be suspended

during the period of shutdown.

2.3 Company makes no representation, assurance or warranty that capacity will

be available on Company's pipeline system at any time and Shipper agrees that Company

shall bear no responsibility or liability to any person if capacity does not exist on any

day to provide service hereunder.
