GENERAL TERMS AND CONDITIONS

(Continued)

6.1(e) (continued)

(vi) Scheduling of Intraday Nominations shall be based on the

elapsed pro rata scheduled quantities.

Elapsed-prorated-scheduled quantity means that portion

of the scheduled quantity that would have theoretically

flowed up to the effective time of the Intraday

Nomination being confirmed, based upon a cumulative

uniform hourly quantity for each Nomination period

affected. (NAESB Definition 1.2.12)

(vii) Intraday Nominations may be submitted to increase or

decrease total Gas flow and may be used to change

Point(s) of Receipt and Delivery. (NAESB Standard

1.3.11) Intraday Nominations may be used to Nominate new

supply or market. (NAESB Standard 1.3.33)

(viii) Intraday Nominations do not rollover (i.e. Intraday

Nominations span one Day only). Intraday Nominations do

not replace the remainder of a standing Nomination.

There is no need to re-nominate if Intraday Nomination

modified existing Nomination. (NAESB Standard 1.3.13)

Intraday Nominations which are not able to be Confirmed

are considered to be void.

(ix) Intraday Nominations shall be considered complete upon

Transporter's receipt of a valid Nomination and the

corresponding up and downstream confirmations.

(x) Transporter will re-determine scheduled quantities,

pursuant to the scheduling priorities of this Section 6,

at the Evening, Intraday 1 and Intraday 2 Nomination

Cycles when such scheduled quantities are affected by a

discount requested by Shipper and granted by

Transporter. Such re-determination may cause a

discounted Firm Shipper that received a discount after

gas has been scheduled to be Bumped.
