GENERAL TERMS AND CONDITIONS

-----------------------------

(continued)

27. TRANSPORTER'S USE

(a) Shipper shall furnish gas for Transporter's Use in the following manner:

Shipper shall tender to Transporter, for Transporter's Use, quantities of gas, in addition

to Shipper's Scheduled Daily Delivery for Transportation Service, equivalent to the total

Gas Tendered times the percentage determined by Transporter for the calendar month during

which the deliveries are made for the services applicable to Shipper.

As such, the Scheduled Daily Delivery for Transportation divided by one less the applicable

Transporter's Use percentage shall be equal to the total Gas Tendered. The applicable

Transporter's Use percentage shall be determined based on each seventy-five (75) miles of

Transportation or fraction thereof.

FORMULA

SDD / (1 - TU%) = GT where

GT = Gas Tendered for Transport and Transporter's Use

TU% = Transporter's Use percentage

SDD = Scheduled Daily Delivery

(b) The applicable percentages will be communicated to Shipper by way of Transporter's Web Site

by the fifteenth (15th) day of the preceding month or will be faxed to any Shipper

requesting such percentages after such percentages are posted to Transporter's Web Site.

Such percentages shall be within the maximum and minimum percentages for each seventy-five

(75) miles of Transportation or fraction thereof set forth on Sheet No. 6 of Second Revised

Volume No. 1.

(1) By the fifteenth (15th) day of the preceding month, Transporter will make the

following calculations. Transporter will compare the actual system Transporter's Use

to the Transporter's Use tendered by all Shippers for the prior month (including any

remaining over or underrecovery from the preceding prior period). Separate

comparisons will be made for (1) fuel and other use gas, which is subject to the per

seventy-five (75) mile allocation; and (2) lost and unaccounted gas, which is

allocated volumetrically. These comparisons will be used to determine the Prior

Period Difference for the applicable period.

(2) The Prior Period Difference, positive or negative, will be included in determining the

Transporter's Use percentages applicable to the next calendar month. Except as

provided in the preceding sentence, the Transporter's Use percentages applicable to a

calendar month shall be based upon forecasted Transporter's Use gas.

(d) Transporter shall file with the Commission, by July 31st and January 31st of each year, the

calculations supporting the Transporter's Use Percentages that were charged in each of the

preceding six months. At any time deemed appropriate by the Transporter, the Transporter

may adjust the minimum and/or maximum percentages set forth on Sheet No. 6 of this Second

Revised Volume No. 1. Transporter shall file with the Commission such revised percentages.

The filing shall be based upon the Transporter's past experience adjusted for any

cumulative over or under-recovery of Transporter's Use existing as of the month preceding

the month of the filing.
