GENERAL TERMS AND CONDITIONS

(continued)

18. CURTAILMENT

18.1 General. This section sets out the procedures whereby KLNG will

reduce or discontinue firm or interruptible services available under

this tariff. If, due to any cause whatsoever, the capacity of

KLNG's storage facility, or any part thereof, is impaired so that

KLNG is unable to store or deliver in the gaseous phase the total

quantity of gas which KLNG is then obligated to store or deliver in

the gaseous phase under agreements with Customer, then KLNG shall

allocate such reduced available capacity in accordance with this

Section 18, subject to the terms of KLNG's existing lease agreement

with Providence Gas.

18.2 Causes of Curtailment. KLNG shall have the right to curtail,

interrupt, or discontinue service in whole or in part from time to

time and at any time (a) for reasons of force majeure or when

necessary, in KLNG's reasonable judgment, to meet its facility

operating requirements or other service obligations, (b) to perform

routine maintenance, repairs, improvements and regulatory compliance

activity, provided that KLNG shall utilize due diligence to schedule

such activity so as not to disrupt confirmed service and shall

provide reasonable notice of such interruptions to Customer, (c) to

the extent, in KLNG's reasonable judgment, such service would impair

KLNG's ability to meet its firm service obligations or to render any

future service that may be provided by KLNG on a firm basis, (d) to

the extent necessary in KLNG's reasonable judgment to comply with

applicable laws and regulations including, but not limited to,

governmental permits governing the operation of KLNG's facilities,

and (e) to the extent necessary in KLNG's reasonable judgment to

protect people and property, including KLNG's facilities, from harm

or damage due to operational or safety conditions.

curtailed then KLNG shall reduce each Customer's scheduled service

in the following order:
