7. EXCESS INJECTIONS AND APPORTIONMENT OF REQUESTED QUANTITIES

On any day for which Buyer, through the injection notice required by

Subparagraph 2.2, requests Transporter to receive for injection

Quantities of Gas in excess of said Buyer's Maximum Daily Injection

Quantity, together with the applicable Injection Allowance, Transporter

shall determine what, if any, portion of the excess Quantity of Gas it

will receive, subject always to Transporter's firm obligation to receive

gas scheduled for injection by other Buyers under Transporter's Rate

Schedules ESS, FSS, SS-1 and SS-2 up to their Maximum Daily Injection

Quantities. Transporter may, in making such determination, take into

account the fact that one or more other such Buyers have scheduled

Quantities of Gas for injection which are less than their Maximum Daily

Injection Quantities, but Transporter shall not be obligated to receive

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 receive excess

Quantities of Gas to the extent consistent with such determination.

Where two or more such buyers request the injection of excess Quantities

of Gas on any day and Transporter so determines that it will inject a

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

shall apportion the excess Quantity of Gas to be injected 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

Injection Quantities and shall receive excess gas accordingly.

8. EXCESS WITHDRAWALS AND APPORTIONMENT OF REQUESTED VOLUMES

On any day for which Buyer, through the withdrawal notice required by

Subparagraph 2.3, requests Transporter to withdraw and deliver to or for

the account of said Buyer Volumes of Gas in excess of its Maximum Daily

Withdrawal Quantity, net of the applicable Withdrawal Allowance,

Transporter shall determine what, if any, portion of the excess Quantity

of Gas it will withdraw and deliver, subject always to Transporter's

firm obligation to withdraw and deliver gas scheduled for withdrawal by

other Buyers under Transporter's Rate Schedules ESS, FSS, SS-1 and SS-2

up to their Maximum Daily Withdrawal Quantities.
