GENERAL TERMS AND CONDITIONS (Cont'd)

(d) Each nomination shall be considered an original nomination and shall be replaced to be changed.

When a nomination includes a date range, each day within that range is considered an original nomination.

When a subsequent nomination is received for one or more days within that range, the previous nomination is

superseded by the subsequent nomination only to the extent of the days specified. The days of the previous

nomination outside the range are unaffected. Nominations have a prospective effect only. Subsequent

nominated quantities shall represent replacement daily quantities.

(e) Transporter will support the following nomination cycles:

(1) "Timely Nomination Cycle" is 11:30 a.m. for nominations leaving control of the nominating

party; 11:45 a.m. for receipt of nominations by the Transporter (including from Title Transfer Tracking

Service Providers (TTTSPs)); noon to send Quick Response; 3:30 p.m. for receipt of completed

confirmations by Transporter from upstream and downstream connected parties; 4:30 p.m. for receipt of

an Evening Nomination that does not cause another Shipper on the subject Transporter to receive notice

that it is being bumped should be effective at 9:00 a.m. on next Gas Day; and when an Evening

Nomination causes another Shipper on the subject Transporter to receive notice that it is being bumped,

the scheduled quantities should be effective at 9:00 a.m. on next Gas Day.
