GENERAL TERMS AND CONDITIONS

(continued)

gas flow, and (ii) a nomination received after the nominations deadline for the

following Gas Day. At least one (1) intra-day nomination can be submitted 4

hours prior to gas flow. Within four (4) hours of an intra-day nomination,

Algonquin will notify affected Customer(s) and point operator(s) of changes in

scheduled quantities. Any scheduling nomination submitted after the initial

scheduling nomination shall contain Customer's anticipated service requirements

for one Day only and shall include the effective date and time. Intra-day

nominations do not replace the remainder of a standing nomination. There is no

need to re-nominate if an intra-day nomination modifies an existing nomination.

The interconnected parties shall agree to the hourly flows for the intra-day

nomination.

If Customer submits an intra-day nomination on the same contract which already

has been scheduled to flow through a Posted Point of Restriction, such intra-day

nomination may be scheduled by Algonquin provided that the intra-day nomination

has a scheduling sequence priority that is being scheduled and allowed to flow on

the same Gas Day as the intra-day nomination pursuant to Sections 23.1 and 48.3

of the General Terms and Conditions and provided that the intra-day nomination

does not result in a net increase in the total volume scheduled on the contract

through the Posted Point of Restriction on that Gas Day.

(d) Elapsed Prorated Scheduled Quantity. With respect to intraday nominations for

reductions in previously scheduled quantities, Algonquin will accept, subject to

the limitations set forth in Sections 22.4(b) and 22.4(c), any explicitly

confirmed quantity, down to and including zero, for such intraday nomination;

provided, however, if such intraday nomination requires confirmation from an

upstream and/or downstream interconnected pipeline then any intraday nomination

to reduce previously scheduled quantities will be subject to, and limited to, the

reduced quantity confirmed by such upstream and/or downstream interconnected

pipeline.

22.5 Minimum NAESB Nomination Standards. In the event the more flexible nomination

procedures set forth in Section 22 above are inapplicable for any reason, nominations

shall be submitted and processed in accordance with the minimum standards set forth in

this Section 22.5. Algonquin shall support the following standard nomination cycles:

(a) The Timely Nomination Cycle: 11:30 am for nominations leaving control of the

nominating party; 11:45 am for receipt of nominations by Algonquin (including

from Title Transfer Tracking Service Providers (TTTSPs)); noon to send Quick

upstream and downstream connected parties; 4:30 pm for receipt of scheduled
