RATE SCHEDULE LFT

Firm Throughput Service

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

For Overrun Volumes transported, the monthly billing shall

be the sum of said overrun units transported daily

multiplied by the Overrun Rate shown on Sheet No. 53.

Unless otherwise mutually agreed to by Northern and Shipper,

all rates for service under (a), (b), and (c) above, of this Rate

Schedule, shall be within the minimum and maximum levels shown on

Sheet Nos. 51 and 53, respectively. The rate(s) Shipper shall pay

will be set forth in Shipper's Service Agreement, or otherwise agreed

to in writing. Northern will provide similar rates to similarly

situated Shippers upon request.

Other rates and charges for services under this Rate Schedule shall

include each of the following:

(d) G.R.I. and A.C.A. Charges

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

Shipper shall pay the applicable Gas Research Institute Charge

("G.R.I.") pursuant to Section 35 of the "GENERAL TERMS AND

CONDITIONS" and the Annual Charge Adjustment ("A.C.A.") pursuant

to Section 36 of the "GENERAL TERMS AND CONDITIONS" for volumes

transported for Shipper.

(e) Fuel

----

This Section (e), "Fuel", shall apply to all throughput.

In addition to the daily quantities delivered, prior to the

beginning of each calendar month Shipper shall elect to either:

(1) provide the appropriate Fuel; or

(2) purchase the appropriate Fuel from Northern at a mutually

agreed upon price.

The scheduling priority for Fuel shall be the same priority as the

respective volumes scheduled to flow. The overall Fuel and

unaccounted for percentages are set forth on Sheet No. 54, and

detailed by receipt-to-delivery MID path on Sheet Nos. 61-64 of this

Tariff.

A Shipper's fuel and unaccounted for is determined by multiplying the

volumes at the receipt point by the applicable receipt-to-delivery

MID path rate as shown on Sheet Nos. 61-64. If the Shipper's receipt

point is a mainline fuel point, the applicable fuel rate is the

"ML Fuel" rate from the MIDs matrix. If the Shipper's receipt point

is a field fuel point, the applicable fuel rate is the "TOTAL" rate

from the MIDs matrix.
