IB RATE SCHEDULE INTERRUPTIBLE BALANCING SERVICE
                                  (Continued)
6.      AUTHORIZATION, RATES, TERMS AND CHANGES
6.1     The Hub Services Agreement and the respective obligations of the
parties hereunder are subject to all valid laws, orders, rules and regulations
of duly constituted authorities having jurisdiction, and are conditioned upon
the issuance, by the FERC, and any state or local governmental agency having
jurisdiction, of requisite authorization for Liberty to provide the balancing
service contemplated hereby and to construct and operate the Gas storage
facilities necessary to provide such balancing service and for any connected
pipeline to transport Gas to/from the Point(s) of Receipt/Delivery necessary to
effect the balancing service provided for herein.
6.2     Liberty shall have the right to propose to the FERC or any other
governing regulatory body such changes in its rates and terms of service as it
deems necessary, and the Hub Services Agreement shall be deemed to include any
changes which are made effective pursuant to order or regulation or provisions
of law, without prejudice to Customers right to protest the same; provided,
however, that any market-based rates negotiated between Liberty and its
Customer(s) shall remain in effect during the term of Exhibit B of the Hub
Services Agreement(s) specifying such rates.
7.      CURTAILMENT
If, due to any cause whatsoever, Libertys capability to receive or deliver
quantities is impaired so that Liberty is unable to receive or deliver the
quantities provided for in Exhibit B of the Hub Services Agreement with
Customers, then capacity, withdrawals, and/or injections will be allocated
according to the priority of service as set forth in Section 5 of the General
Terms and Conditions of this FERC Gas Tariff.
8.      EXPIRATION OF TERM
At least ten (10) Business Days prior to the end of the term as specified in
Exhibit B of Customers Hub Services Agreement, Liberty shall notify Customer
to withdraw all of the IB Gas quantities held in storage by Liberty for the
account of Customer; provided, however, any Exhibit B of Customers Hub
Services Agreement that has a term of ten (10) Business Days or less shall not
require such foregoing notice but shall be deemed to have been given upon the
first Day of the primary term or the renewed term of such Hub Services
Agreement.     Libertys notice to Customer may be given orally, but shall be
confirmed in writing via e-mail or facsimile to the Customer.  Before the end
of the term of Exhibit B of Customers Hub Services Agreement, the Customer
must either physically withdraw the Gas or indicate to Liberty in writing that
it desires to have Liberty cash out the Gas on mutually agreeable terms.  If,
by midnight on the last Day of the term of Exhibit B of Customers Hub Services
Agreement, the Customer neither has withdrawn the Gas nor indicated in writing
to Liberty that it desires to
exercise the cash out option, then Liberty may take, free and clear of any
adverse claims, title to such IB balance quantity as Customer was required to
withdraw or cash out; provided, however, that if Customer was unable to
withdraw its IB balance quantity due to an interruption of Customers
withdrawal service during the last ten Days before termination, Customer shall
be allowed to withdraw its Gas within a reasonable period following the end of
the contract term.
In the event that Liberty retains and takes title to any of Customers Gas
pursuant to this Section, Liberty shall dispose of such Gas by auction and
shall credit the net proceeds received from such auction in accordance with the
provisions of Section 33 of the General Terms and Conditions of this FERC Gas
Tariff.
