(4) Fourth, Transporter shall accept all

nominations for service under Hub Service Contracts where

such service positively impacts the operations of

Transporter's system. Transporter shall also accept all

timely nominations for those Shippers receiving park and

loan service under the PAL Rate Schedule or point operators

receiving service under OBAs which have requested 250 Dth

or less on a day.

(5) Fifth, Transporter shall accept all

nominations for service under Gas Transportation Contracts

for Interruptible Service up to the Maximum Input

Quantities and Maximum Equivalent Quantities contained in

such Gas Transportation Contracts. Transporter shall also

accept all nominations for hub service (loan and

transportation) where the cumulative quantity for such

nominations does not exceed the Maximum Balance contained

in such service contracts and shall accept the nominations

for hub service (loan payback). Such acceptance shall be

subject to the following provisions.

In the event Transporter has insufficient capacity to

render the full level of interruptible or hub

transportation service nominated, Transporter shall

allocate the transportation service available based on the

highest percentage of the applicable maximum commodity

rate(s) for the service being provided. Shippers that are

paying the same percentage of the applicable maximum

commodity rate(s) for such service shall be allocated

capacity on a pro-rata basis.

In applying such criteria where a Negotiated Rate or

Negotiated Rate Formula is involved, the value assigned to

a request which includes a Negotiated Rate or Negotiated

Rate Formula shall be determined in accordance with Section

32 of these General Terms and Conditions and shall in no

event exceed the Recourse Rate. Shippers that are paying

the same percentage of the applicable maximum commodity

rate(s) for such service shall be allocated capacity on a

pro-rata basis.

Transporter shall accept all Hub Service loan payback

nominations in the order in which they are received.

The acceptance of hub service nominations as provided

heretofore is subject to the first twenty-five (25) MDT of

system linepack available each day for hub service, park

and loan service, and scheduled OBA requests being reserved

exclusively for unscheduled imbalances with point operators

(such twenty-five (25) MDT quantity will be increased by

three percent (3%) of any mainline facility expansion), and

provided further that Transporter shall consider

notifications from a point operator

that, after exhausting all other alternatives, it has been,

or reasonably expects to be, experiencing operating

conditions on its system that will require that point

operator to delay accepting delivery of scheduled

transportation quantities under Transporter's RTS Rate

Schedule.
