12. RESERVATION CHARGE ADJUSTMENTS

12.1 Daily. If during any day, Transporter fails to deliver to Shipper

the quantity of natural gas requested by Shipper up to the

Transportation Contract Demand, the Reservation Charge otherwise

payable during the month in which such day occurs shall be reduced

by an amount computed by multiplying the quantity Transporter so

failed to deliver to Shipper on such day by an amount per MMBtu

obtained by dividing the monthly unit Reservation charge by 30.4,

rounded to the nearest one-hundredth of a cent per MMBTU.

12.2 The adjustments provided in this Section 12 shall not apply if

Transporter's failure to deliver the peak day or annual volume

requested was due to Shipper's failure to deliver such gas to

Transporter or to Shipper's inability to accept delivery of such

gas, or to interruptions of service under Section 10 of the General

Terms and Conditions.

12.3 The reduction to the Reservation Charge otherwise payable as

mentioned above, shall not be due Shipper if Shipper does not

endeavor, using its best efforts, to obtain gas supplies from

locations behind alternate receipt points (as specified in Shipper's

TF-1 service agreement or which can be made available to Shipper

under the flexible receipt point provisions in Section 12 of this

Rate Schedule), from which there are no capacity constraints to

Shipper's nominated delivery points.
