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.
