GENERAL TERMS AND CONDITIONS

(continued)

24. CURTAILMENT

24.1 General. This Section 24 sets out the procedures whereby Algonquin will reduce or

discontinue firm or interruptible services available under this tariff. If, due to any

cause whatsoever, the capacity of Algonquin's transmission system, or any part thereof,

is impaired so that Algonquin is unable to receive or to deliver the total quantity of

gas which Algonquin is then obligated to receive or to deliver under agreements with

Customer, then Algonquin shall allocate such reduced available capacity in accordance

with this Section 24.

24.2 Causes of Curtailment. Algonquin shall have the right to curtail, interrupt or

discontinue service in whole or in part on all or a portion of its system from time to

time and at any time (a) for reasons of force majeure or when necessary, in Algonquin's

reasonable judgment, to maintain the operational integrity of its system, (b) to

perform routine maintenance, repairs, improvements and regulatory compliance activity,

provided that Algonquin shall utilize due diligence to schedule such activity so as to

minimize disruptions of service and shall provide reasonable notice of such

interruptions to Customer, (c) when the service is interruptible to the extent, in

Algonquin's reasonable judgment, such interruptible service would impair Algonquin's

ability to meet its firm service obligations, (d) to the extent necessary in

Algonquin's reasonable judgment to comply with applicable laws and regulations

including, but not limited to, governmental permits governing the operation of

Algonquin's facilities, and (e) to the extent necessary in Algonquin's reasonable

judgment to protect people and property, including Algonquin's facilities, from harm or

damage due to operational or safety conditions including but not limited to conditions

such as excessive compressor discharge temperatures.
