26. DISPOSITION OF EXCESS GAS

Transporter may make interruptible sales of gas from time to time to

provide fuel and use quantities to Shippers. Further, in order to alleviate

conditions that threaten the integrity of its system, Transporter may

periodically acquire quantities of gas that are excess to system needs.

Transporter shall have the right to make interruptible sales of such excess gas

from time to time at system Receipt Point pursuant to the terms of the blanket

certificate of public convenience and necessity granted to Transporter pursuant

to 18 C.F.R. Section 284.284(6). Such sales shall be made under rates,

terms and conditions mutually agreed upon between Transporter and purchasers,

provided, however, that all such sales shall be fully interruptible and shall

be curtailable pro rata without regard to underlying transportation

arrangements made by purchasers.
