                                       RATE SCHEDULE FDD
                                 Firm Deferred Delivery Service

       Billing for FDD service will commence in accordance with Section 6 of this Rate
       Schedule.

       Northern may file with and seek Commission approval under Section 4 of the Natural Gas
       Act to change any rates or charges set forth in this Rate Schedule from time to time,
       whenever in Northern's judgment such change is necessary to assure just and reasonable
       rates.  Northern shall notify Shipper of such filing in accordance with Section 4(d) of
       the Natural Gas Act.  Northern may collect such change in rates in accordance with
       Section 4(e) of the Natural Gas Act.

       Transportation Service Associated with Storage Service
       ----------------------------------------------------------------
       Deliveries and redeliveries of the FDD quantities shall be subject to the rates, terms
       and conditions of the upstream or downstream Firm or Interruptible Throughput Service
       Agreement.

       A transportation rate and fuel is charged both into and out of a Field Area storage
       point.  Except as provided below with regard to a transportation point and its associated
       storage point, a transportation rate and fuel is charged for delivery to the Ogden
       storage point.  If redelivery from Ogden is to a Market Area point, there is no
       additional transportation or fuel charge.  If the redelivery is to a Field Area point,
       the Field Area mileage/MID transportation rate and fuel is charged.  To the extent a
       volume is transported between a transportation point and its associated storage point, no
       transportation fee or fuel shall be assessed.  With the exception of Ogden, to the extent
       a volume is transported from a storage point to a transportation point other than its own
       associated transportation point then a transportation fee and fuel will be assessed.

       When the Ogden storage point is used, the Shipper must use the same type of service
       (i.e., firm or interruptible) to transport to and from the storage point, unless agreed
       to otherwise by Northern on a non-discriminatory basis.  However, in the event Shipper
       has used interruptible service into the FDD account, Shipper may utilize released
       capacity, under the terms and conditions of Section 47, Capacity Release, to transport
       quantities from the FDD account.
