IR-1 RATE SCHEDULE

Hub Service - Imbalance Resolution Schedule

3. RATE

3.1 The maximum and minimum rates per Dth delivered to Shipper for

Imbalance Resolution Service under are set forth on the currently

effective Sheet No. 9 of this tariff. These rates shall be

applicable to service hereunder, unless Transporter and Shipper

have agreed upon a negotiated rate pursuant to Section 17.2 of

the General Terms and Conditions of this Tariff. These rates

include a First Day charge for the quantities of gas for the day

of advance and a charge for each subsequent day until the return

of the gas on a first-out first-in basis. The current Posted

Rate (ranging between the maximum and minimum rates) will be

posted on Transporter's Web Site, which is subject to periodic

changes. Shipper shall pay the current Posted Rate on the date

the Shipper's Hub Nomination Form is received, as verified by

telephone approval, and Shipper's IR-1 service agreement will be

deemed to be so amended.

3.2 If during the term of a IR-1 Service Agreement, Transporter posts

a lower Posted Rate on the Web Site, Shipper's IR-1 service

agreement will be deemed amended to reduce the rate to the

current Posted Rate for the term of the Nomination; provided

however, if the current Posted Rate is subsequently increased

during the term of that Nomination, the IR-1 service agreement

will be deemed amended to reflect the increased rate but no more

than the then-current Posted Rate at the commencement of such

Nomination.

3.3 Transporter will retain the percent of receipts set forth on

Sheet No. 9 as "Fuel and Company Use retention" and the percent

of receipts set forth on Sheet No. 9 as "Transportation LAUF

retention".

3.4 Transporter is not obligated to offer to resolve imbalances or to

resolve imbalances at any rates less than the maximum rates

specified for this Rate Schedule on Sheet No. 9; however, nothing

precludes Transporter from charging a rate between the maximum

and minimum rates (the current Posted Rate) for this service

under this Rate Schedule.
