FERC Gas Tariff                                                                           Superseding

                                     RATE SCHEDULE TF
                                 Firm Throughput Services

  Point(s) of Receipt to the Point(s) of Delivery.  The Market Area "Total Aggregate
  MDQ" shall mean the sum of the TF12 Base, TF12 Variable and the TF5 MDQs.  The TFF MDQ
  is the entitlement the Shipper has from Field Area receipt points to the F/M Demarcation.  The
  TFF MDQ is not included in the Total Aggregate MDQ.  A Shipper is permitted to combine
  multiple TF Agreements into a single TF Agreement to the extent that the individual
  Agreement's rates, terms and conditions can be distinctly maintained within Northern's
  contracting and billing systems.

  Shipper shall have the option to request firm throughput service (i) solely for the
  Market Area, (ii) solely for the Field Area, or (iii) a combined service for both the
  Market and the Field Area.  The Shipper's ability to utilize primary and alternate flexible
  receipt and delivery points is determined by which option is chosen by the Shipper. A Shipper
  with a combined Market and Field Area service agreement may not transfer a primary firm
  receipt or delivery point from the Field Area to the Market Area for the term of the TF
  agreement.

  Subject to the terms of this paragraph, a Shipper may select the full requirements option.
  Under such option, a Shipper will agree to take its full requirements from Northern for the
  service territory currently served by the existing entitlement and the growth associated with
  such service territory and agree not to physically bypass Northern for such territories for
  the term of the agreement.  In exchange for such agreement, Shipper and Northern may mutually
  agree to increase the Shipper's contract demand at agreed upon intervals, to construct new
  facilities if necessary and to exercise commercially reasonable best efforts to secure
  approvals for such construction. To the extent new facilities would need to be constructed to
  meet Shipper's growth requirements, Northern will hold open seasons for any construction
  required and will provide service to any requesting Shipper whose request meets the economic
  feasibility requirements for the construction of facilities.

  Receipt Points
  --------------

  a)  Amount of Receipt Point Capacity

      Disregarding differences in capacity due to fuel and unaccounted for, each existing
      Shipper's contract may reserve receipt point capacity up to one hundred fifteen percent
      (115%) of the Total Aggregate MDQ, except as provided herein.  The rate for receipt
      capacity reserved in excess of delivery capacity is one-half of the TF12 Base monthly
      reservation charge per MMBtu set forth on Sheet No. 50.  Pooling point(s) as referenced in
      Section 28 of the GENERAL TERMS AND CONDITIONS of this Tariff and the deferred delivery
      point if elected as a primary receipt point, are not eligible for the additional fifteen
      percent (15%) of receipt point capacity since the initial entry receipt point into
      Northern's system has utilized the additional fifteen percent (15%).  However, capacity
      reserved at any one receipt point cannot be greater than one hundred percent (100%) of the
      MDQ.  Regardless of the receipt point capacity reserved above 100% of MDQ, MDQ is the
      maximum daily volume of natural gas that Northern is obligated to transport and
      deliver to Shipper and Shipper is entitled to receive pursuant to this Rate
      Schedule, subject to provisions of Section 29 of the "GENERAL TERMS AND
      CONDITIONS" of this Tariff.  No new contracts will be allowed receipt point capacity in
      excess of delivery point capacity.
