GENERAL TERMS AND CONDITIONS

(continued)

10. ASSIGNMENT AND CURTAILMENT OF CAPACITY (continued)

capacity or deliverability to meet system operating

requirements or other higher priority service obligations

as specified in the Tariff, upon such notice as is

reasonable under the circumstances. If the conditions or

events which caused the interruption or curtailment are

anticipated to continue, scheduling of services pursuant to

Section 5 shall be implemented to the extent required in

conformity with the provisions of this section. Subject to

Transporter's evaluation of the operational conditions and

circumstances that exist on Transporter's pipeline at the

time, in such event firm transportation and storage

services, to the extent timely nominated and scheduled,

shall have a priority over interruptible services. In the

event such curtailment is required, whether systemwide,

within a Pooling Area or with regard to a particular

pipeline or storage segment, as determined by Transporter,

Transporter shall reduce scheduled services in the affected

segment(s), to zero if necessary, in accordance with the

following:

Category One: Except as otherwise specified in the

applicable Rate Schedule or specifically provided for

in the Tariff, all Gas scheduled under Rate Schedules

IT, PHS (interruptible and overrun wheeling), FT/FT-

2/EFT (overrun), FSS(overrun), RSS(overrun), ISS or PS

(interruptible Pool Transfers only), as applicable,

shall be curtailed first, provided that Transporter

may curtail or discontinue services for Gas scheduled

for delivery or being delivered at lower rates prior

to the curtailment of services scheduled at higher

rates. Otherwise, Transporter shall curtail such

services on a pro rata basis based upon each Shipper's

scheduled quantities.
