GENERAL TERMS AND CONDITIONS

(continued)

2. REQUEST FOR TRANSPORTATION SERVICE (continued)

2.5 Open Season for Available Capacity.

Upon receipt of a valid request for firm service pursuant to Section 2.4 with a term

greater than thirty (30) days for which Algonquin determines capacity is available to

satisfy any such request, Algonquin shall post notices for solicitation of bids in an

open season for service to start immediately or in the future. For valid requests for

firm service pursuant to Section 2.4 with a term of thirty (30) days or less for which

Algonquin determines capacity is available to satisfy any such request, Algonquin shall

have the right, but shall not be obligated, to post notices for solicitation of bids in

an open season on such capacity. In addition, Algonquin shall post notices for

solicitation of bids in an open season for significant mainline or lateral capacity

expansion projects on its system; provided, however, that an open season shall not be

required for minor or auxiliary facilities, additions of receipt and/or delivery

facilities or facility modifications which do not significantly alter the operational

characteristics of the pipeline system.

For any open season conducted pursuant to this Section 2.5 for service with a term of

less than ninety (90) days, the open season will be conducted for a minimum of one (1)

Business Day. For an open season under this Section 2.5 for service with a term equal

to or greater than ninety (90) days that is not otherwise associated with an expansion

project, the open season will be conducted for a minimum of (i) five (5) Business Days

from the posting of the notice of request for service for the capacity or (ii) fifteen

(15) Business Days from the date the capacity in question was first posted as being

available for contracting, whichever is the later calendar date. In no event shall the

open season be for a period greater than one (1) calendar month. All open seasons shall

end at 2:00 p.m. CT not less than one (1) Business Day prior to the date service would

be available. The open season may include generally available unsubscribed capacity;

capacity under expiring or terminating service agreements, to the extent such agreements

do not have a right of first refusal or the subject shipper does not exercise the right

of first refusal; and/or capacity resulting from one or more expansion projects.

Algonquin will post available capacity before it provides such information to any

potential customer.

(a) The open season notice will include the following:

(1) the location of the capacity or proposed expansion;

(2) the total quantity, unless such quantity is not known or knowable;

(3) the date capacity is available or proposed to be available; and

(4) the dates on which the open season begins and ends.

Algonquin will attempt to structure any such open season posting pursuant to this

Section 2.5 so as not to identify specifically the Customer or potential customer

submitting the request and/or the specific location of the market(s) to be served.
