GENERAL TERMS AND CONDITIONS

(continued)

25.IMBALANCE RESOLUTION PROCEDURES (continued)

Algonquin will provide the ability to post and trade imbalances at any

time during the gas flow Month, and until the seventeenth Business Day

after the end of the Month. To facilitate the trading process,

Algonquin will, upon receipt of Cash-out Party's authorization, post a

Cash-out Party's imbalance quantity on its Web Site. Authorizations

to Post Imbalances that are received by Algonquin by 11:45 a.m. will

be effective by 8:00 a.m. the next Business Day (central clock time).

An Authorization to Post Imbalances will remain in effect until

cancelled by the Cash-out Party. Imbalances previously authorized for

posting will be posted as they become available, but no later than the

ninth Business Day of the Month; however, Algonquin will not be

required to post zero imbalances. The information posted will also

identify the Cash-out Party, the contract, the Operational Impact Area

and the gas flow Month applicable to the posted imbalance quantity.

For purposes of determining the imbalance quantity that will be

posted, all imbalances within an Operational Impact Area due Cash-out

Party under all of Cash-out Party's contracts and all imbalances in

that Operational Impact Area due Algonquin under all of Cash-out

Party's contracts shall be summed together to yield a single net

imbalance quantity for the Cash-out Party in that Operational Impact

Area for the Month, unless otherwise agreed to pursuant to Section

25.9 below. Algonquin will provide to all Customers the ability to

view, and upon request, download posted imbalance information.

Algonquin shall enable the imbalance trading process by (i) receiving

the Request for Imbalance Trade, (ii) receiving the Imbalance Trade

Confirmation, (iii) sending the Imbalance Trade Notification to all

affected parties, and (iv) reflecting the trade prior to or on the

next monthly Customer Imbalance or cashout. When trading imbalances,

the quantity to be traded must be specified. After receipt of an

Imbalance Trade Confirmation, Algonquin will send the Imbalance Trade

Notification to the initiating trader and the confirming trader no

later than noon (central clock time) on the next Business Day.

Imbalance trades can only be withdrawn by the initiating trader and

only prior to the confirming trader's confirmation of the trade.

Imbalance trades are considered final when confirmed by the confirming

trader and effectuated by Algonquin. Algonquin shall update the Cash-

out Party's imbalance data to reflect any final trades of imbalance

quantities no later than 9:00 a.m. CT on the next Business Day after

the trade is finalized.
