3.1 Applicable Rates: The rates for service hereunder shall, subject to

other provisions hereof, be the rates agreed to by Transporter and

Operator as set forth in Exhibit "A" to the Agreement, provided that

such rates shall not be less than the minimum nor more than the

maximum rates for service pursuant to this Rate Schedule, or any

effective superseding tariff on file with the FERC.

3.2 Commodity Charge. The Operator shall be charged an amount each Month

obtained by multiplying a Commodity Rate as set forth in Exhibit A

to the Agreement by the end-of-day quantities allocated to the

Agreement at each designated Point of Delivery which exceeds the

greater of 5 percent or 100 Dth of the daily total Scheduled

Quantities at such Points of Delivery during the Month.

3.3 Adjustment of Rates: Subject to the terms of the Agreement,

Transporter reserves the right to prescribe and/or to adjust at any

time any of the rates applicable to any individual Operator without

adjusting any other rates for that or another Operator; provided,

however, that such adjusted rate shall not exceed the

applicable maximum rate nor shall it be less than the applicable

shall provide Operator with daily and cumulative balances of

overdeliveries and underdeliveries which are allocated to the

Agreement.

b) Operators are expected to use reasonable efforts to adjust, or

cause to be adjusted, the Nominations to the designated High

under the Agreement to net to zero.
