RATE SCHEDULE IBS (continued)

5.2 The Access Charge shall be the product of the then effective

applicable Daily Access Rate under the IBS Agreement multiplied by

the sum, for each Gas Day of the billing month, of the absolute Dth

quantity of Access Requests nominated by Shipper and confirmed by

Transporter. Confirmed Access Request quantities for balancing

increases from nominations ("swing-up loans") are added to Access

Requests for balancing decreases ("swing-down parks") and are not

netted in deriving the absolute quantity for purposes of billing of

the Access Charge.

5.3 The maximum and minimum rates applicable to this Rate Schedule IBS

are set forth in the Currently Effective Rates section of this

Tariff. Unless otherwise agreed to in writing or as set forth

herein, maximum applicable tariff rates shall apply to confirmed

daily Access Request quantities.

5.4 By mutual agreement between Transporter and Shipper or as otherwise

set forth herein, discounts or Negotiated Rates may be limited to

specific quantities or periods hereunder.

5.5 Transporter may from time-to-time and at any time, upon twenty-four

(24) hours' oral or written notice, or by Shipper's election to

nominate service consistent with the terms of the applicable service

discount rate offers posted by Transporter on its Interactive

Website from time-to-time, and subject to any provisions on

discounting in the IBS Agreement or in a separate discount

Agreement, and subject to Section 12.6 of the General Terms and

Conditions of this Tariff, charge any individual Shipper for service

under this Rate Schedule IBS a rate which is lower than the

applicable maximum rate set forth in this Tariff; provided, however,

that such rate charged may not be less than the applicable minimum

rate for service under Rate Schedule IBS set forth in this Tariff as

applicable. Transporter will confirm any oral notice of the

applicable rate in writing. Such notification shall specifically

state the effective date of such rate change and the quantity of Gas

so affected. Unless otherwise agreed in the IBS Agreement or in a

separate discount Agreement, Transporter may at any time further

change such rate (subject to any restrictions as to maximum or

minimum rates set out in this Tariff, the IBS Agreement and/or any

discount Agreement) upon twenty-four (24) hours' oral notice to

Shipper, which notice shall be confirmed in writing. Such

notification shall specifically state the effective date of such

rate change and the quantity of Gas so affected. Transporter shall

file with the Commission any and all reports as required by the

Commission's Regulations with respect to the institution or

discontinuance of any discount.
