RATE SCHEDULE LFT
Limited Firm Throughput Service

(i) Overrun Charge. 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.

(ii) Out-of-Balance Charge. The monthly billing shall be the
total units of Out-of-Balance volumes transported to a
delivery point(s) during the respective month multiplied by
the Out-of-Balance Rate as shown on Sheet No. 51 of this
Tariff, as applicable.

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) A.C.A. Charge
-------------

Shipper shall pay the applicable 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.
