GENERAL TERMS AND CONDITIONS

(continued)

25. IMBALANCE RESOLUTION PROCEDURES (continued)

25.7 Imbalance Management Services. The Imbalance Management Services

offered by Algonquin are identified in Section 1 of the General Terms

and Conditions. Details of each service are included in the

applicable Rate Schedule and Form of Service Agreement contained in

this tariff, or in Sections 25.8 and 25.9 below.

25.8 Imbalance Trading. Imbalance Trading is available for any imbalance

that would otherwise be resolved pursuant to Sections 25.9 and 25.10

below. Algonquin shall allow Cash-out Parties to trade imbalances

within the same Operational Impact Area, as defined in Section 1 of

the General Terms and Conditions, if the two Cash-out Parties'

imbalances are offsetting balances for the Month, such that the net

imbalance after the completion of the trade for each Cash-out Party

would be reduced to a quantity closer to zero. A Cash-out Party may

trade any imbalance with another Cash-out Party, provided that any

trades involving OBA imbalances shall not result in a transportation

path which crosses a Posted Point of Restriction, as defined in

Section 1 of the General Terms and Conditions; provided further that,

to the extent that imbalances were incurred on Days when no Posted

Point of Restriction was in effect, those imbalances are available for

trading. An OBA Party that trades an imbalance resulting from actual

deliveries by Algonquin in excess of scheduled deliveries ("due

Algonquin") shall be assessed a transportation imbalance charge. An

OBA Party that trades an imbalance resulting from actual deliveries by

Algonquin that are less than scheduled deliveries ("due OBA Party")

shall be assessed a transportation imbalance credit. The

transportation imbalance charge and the transportation imbalance

credit shall be calculated by multiplying the traded quantity by the

weighted average of the actual Commodity Charges owed on all

quantities of gas delivered during the Month to that OBA Party.
