GENERAL TERMS AND CONDITIONS

13. NOMINATING AND SCHEDULING TRANSPORTATION SERVICE (Cont'd.)

scheduled. Transporter shall not be required to accept an

intra-day nomination whose effect would be to reschedule

quantities of gas flowing for other Shippers under standard

nominations. Transporter shall schedule an intra-day nomi-

nation to the extent that capacity is available. No intra-day

nomination shall be for a quantity that is less than the

quantity of gas that has been scheduled to flow on such day

prior to the effective time of such intra-day nomination. The

last intra-day nomination received with respect to a day shall

be deemed to be the valid nomination for such day and shall

supersede any previous nomination for such day.

timeline should be as follows: 11:30 am central clock time for

nominations leaving the control of the nominating party; 11:45

am for receipt of nominations by Transporter; noon central

clock time for a quick response; 3:30 PM for receipt of

completed confirmations by Transporter from upstream and

downstream connected parties; 4:30 PM for receipt of scheduled

quantities by Shipper and point operator (central clock time

on the day prior to flow). In addition, at the end of each

day Transporter shall make available to Shippers, via EDI,

information containing scheduled intra-day nominations and any

other scheduling changes. The process (excluding timelines)

of quick response, confirming with upstream and downstream

parties and scheduling also applies to intra-day nominations.

Transporter, as receiver of a nomination, initiates confir-

mation with the caveat that the receiver of the confirmation

may relieve Transporter of the obligation to send. The

sending party should adhere to nomination, confirmation, and

scheduling deadlines. It is the party receiving the request

who has the right to waive the deadline. At a receipt or

delivery point, the "lesser of" rule (confirmed or nominated

flow) applies when confirming. If no communication is

received, the lesser of the new nomination or previously

scheduled quantity applies.
