STATEMENT OF EFFECTIVE RATES AND CHARGES

FOR TRANSPORTATION OF NATURAL GAS

Notes:

(a) The mileage component shall be applied per pipeline mile to gas

transported by GTN for delivery to shipper based on the primary receipt

and delivery points in Shipper's contract. Consult GTN's system map on

Sheet 3 for receipt and delivery point and milepost designations.

(b) The non-mileage component is applied per Shipper's MDQ at Primary

Point(s) of Delivery on Mainline Facilities.

(c) The delivery rates are applied per pipeline mile to gas transported by

GTN for delivery to shipper based on distance of gas transported.

Consult GTN's system map on Sheet No. 3 for receipt and delivery point

and milepost designations.

(d) Fuel Use: Shipper shall furnish gas used for compressor station fuel,

line loss, and other utility purposes, plus other unaccounted-for gas

used in the operation of GTN's combined pipeline system in an amount

equal to the sum of the current fuel and line loss percentage and the

fuel and line loss percentage surcharge in accordance with Paragraph 37

of this tariff, multiplied by the distance in pipeline miles transported

from the receipt point to the delivery point multiplied by the

transportation quantities of gas received from Shipper under these rate

schedules. The current fuel and line loss percentage shall be adjusted

each month between the maximum rate of 0.0050% per Dth per pipeline mile

and the minimum rate of 0.0000% per Dth per mile. The fuel and line

loss percentage surcharge is 0.0000% per Dth per pipeline mile. No fuel

use charges will be assessed for backhaul service. The incremental fuel

surcharge, initially established for Shippers utilizing capacity

constructed as part of GTN's 2002 Pipeline Expansion Project at

0.000854% per Dth per pipeline mile, shall be adjusted downward as new

long-term Shippers take capacity that is subject to the incremental fuel

surcharge pursuant to Paragraph 38 of GTN's General Terms and

Conditions. Currently effective fuel charges, including GTN's currently

effective incremental fuel surcharge, may be found on GTN's Internet

website under "Informational Postings."

(e) Reserved For Future Use.
