8. EXCESS WITHDRAWALS AND APPORTIONMENT OF REQUESTED VOLUMES

(Cont'd.)

Transporter may, in making such determination take into account the

fact that one or more other such Buyers have scheduled Quantities of

Gas for withdrawal and delivery which are less than the Maximum Daily

Withdrawal Quantities, but Transporter shall not be obligated to

withdraw and deliver such excess Quantities of Gas except to the

extent that Transporter may, in its sole judgment, determine that it

is expedient for it to do so. Having made such determination,

Transporter will withdraw and deliver excess gas to the extent

consistent with such determination. Where two or more such Buyers

request the withdrawal and delivery of excess Quantities of Gas on any

day and Transporter so determines that it will withdraw and deliver a

portion but not the totality of all such requested Quantities of Gas,

it shall apportion the excess Quantity of Gas to be withdrawn and

delivered on such day among the requesting Buyers under Transporter's

Rate Schedules ESS, FSS, SS-1 and SS-2 in the relation of their

respective Maximum Daily Withdrawal Quantities and shall withdraw and

deliver excess gas accordingly.
