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. 5A 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 Trans-

porter's Electronic Bulletin Board, 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 Electronic Bulletin Board, 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 Nomina-

tion.

3.3 Transporter will retain the percent of receipts set forth on Sheet

No. 5A as "fuel, loss and company-use allowance," except that this

percentage may be discounted as provided in Subsection 3.4 hereof.

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

resolve imbalances at any rates or allowances less than the maximum

rates and allowances specified for this Rate Schedule on Sheet No.

5A; however, nothing precludes Transporter from charging a rate

between the maximum and minimum rates (the current Posted Rate), or

retaining less than the maximum allowance for this service under

this Rate Schedule.
