                                      RATE SCHEDULE LFT
                                Limited Firm Throughput Service

                Alternate Firm Receipt and Delivery Points.
                ------------------------------------------

                Flexibility.  All receipt and delivery points on the system will be available
                for use as alternate firm points (including zone deliveries to a specific
                customer) within the service area provided by the contract and subject to
                operational considerations.

                Discounts.  Any discount granted (reservation or commodity) at the primary
                points will not be automatically granted at the alternate points.

                Reservation Rate.  The reservation rate for the alternate point will be the
                higher of the maximum rate for the alternate point or the maximum rate for the
                primary point.  However, a Shipper may not have point flexibility between the
                Market Area and the Field Area (or vice versa) unless the Shipper has a
                combined Field Area/Market Area contract.

          Northern shall have the right to interrupt or curtail service under this Rate
          Schedule LFT as a result of a force majeure event as defined in Section 10, "Force
          Majeure" of the GENERAL TERMS AND CONDITIONS of this Tariff, or in accordance with
          Section 19, "Limitation of Northern's Obligation to Provide Firm Services" of the
          GENERAL TERMS AND CONDITIONS of the Tariff.  Curtailment shall be in accordance with
          Section 29, "Allocation of Capacity" of the GENERAL TERMS AND CONDITIONS
          of this Tariff.


     3.  OFFERING OF LFT SERVICE.

         To initiate service under this Rate Schedule LFT, a valid request must be submitted in
         accordance with Section 26, "Requests for Service" and Section 27, "Information
         Required for a Request for Service," of the GENERAL TERMS AND CONDITIONS
         of this Tariff.

         LFT capacity available for one month or up to a one-month term will be posted on
         Northern's Internet website for a minimum of one (1) day prior to awarding such
         capacity; LFT capacity available for more than a one-month term will be posted on the
         Internet website for a minimum of two (2) days.  Capacity posted as available for LFT
         Service shall be firm capacity that has not been previously subscribed.

         The minimum level of MDQ applicable to a LFT Agreement under this
         Rate Schedule shall be 50 MMBtu per day.

     4.  TERM OF LFT AGREEMENT.

         The LFT Agreement must be executed by Shipper prior to commencement
         of service.

         The term of service shall be negotiated.  There shall not be a minimum term.  The term
         shall be set forth in the LFT Agreement.

         LFT Agreements at maximum rates for 12 or more consecutive months of service have
         Right of First Refusal as provided in Section 52 of the GENERAL TERMS AND CONDITIONS
         of this Tariff.  LFT Agreements with a term up to, but not including, one (1) year
         shall not be eligible for the Right of First Refusal process.  Discounted LFT
         agreements are not eligible for the Right of First Refusal process.  The service will
         be automatically abandoned upon expiration of the term.

         Northern and Shipper may agree to different termination dates for specified volumes
         within the same Service Agreement on a not unduly discriminatory basis.

         Northern and Shipper may agree, on a not unduly discriminatory basis, to contract
         extensions, including evergreens, rollovers and other extensions.
