Superseding: Ninth Revised Sheet No. 44

Transporter may at any time and from time to time charge any Shipper for

service under this Rate Schedule, a usage charge predicated on a usage

rate that is less than the maximum usage rate set forth from time to

time on the currently effective Sheet No. 20 of this FERC Gas Tariff;

provided, that the usage rate may not be less than the effective minimum

usage rate.

Transporter shall file any and all reports required by the Commission's

regulations setting forth the applicable discounted usage rates and

Shippers affected, along with any other required information.

4. FUEL, LOST AND UNACCOUNTED FOR GAS

In addition to the charges stated herein, each Shipper under this Rate

Schedule will be assessed its proportionate share of Fuel, Lost and

Unaccounted for Gas resulting from System operations. Each Shipper's

deliveries from the System will be reduced by the Fuel, Lost and

Unaccounted for Gas retention rate, as shown on the Statement of

Transportation Rates Sheet No. 20, based upon its total receipts into

the System. Transporter will calculate the actual amount of Fuel, Lost

and Unaccounted for Gas experienced during each calendar Year and file

any revisions to the reduction percentage to more closely approximate

the actual amount of Fuel, Lost and Unaccounted for Gas experienced by

the System and to reflect differences between projections and actual

fuel and losses from the previous calendar Year. The revised percentage

of reduction will be filed to become effective on July 1 of each Year.
