FERC Gas Tariff                                                                           Superseding
Fifth Revised Volume No. 1                                              Fourth Revised Sheet No. 292A

                                    GENERAL TERMS AND CONDITIONS

         I.  Revenues associated with DDVC charges shall be credited to Shippers in accordance with
             Section 57 of the GENERAL TERMS AND CONDITIONS of this Tariff.

         J.  In the event a Shipper would be assessed both a receipt point scheduling penalty and
             DDVC charge for the same scheduling variance from a receipt point to a delivery point,
             Northern will charge the Shipper the higher of the receipt point scheduling penalty or
             the DDVC charge, but not both.

         K.  Northern reserves the right to waive DDVC's in a not unduly discriminatory manner.  In
             the event Northern calls a Critical or SOL Day, negative DDVCs for the affected area
             will be waived. In the event Northern calls an SUL day, positive and punitive DDVCs for
             the affected area will be waived.

         L.  Northern shall provide affected parties with notification of Critical Days through the
             Shipper's choice of Electronic Notice Delivery Mechanism.  Unless the affected party
             and Northern have agreed to exclusive notification via EDI/EDM, the affected party
             should provide Northern with at least one Internet E-mail address to be used for
             Electronic Notice Delivery of notification of Critical Days.  The obligation of
             Northern to provide notification is waived until the above requirement has been met.
             Northern will support the concurrent sending of electronic notification of Critical
             Days to two Internet E-mail addresses for each affected party.  Affected parties will
             manage internal distribution of notices received by Electronic Notice Delivery.

         M.  DDVCs for non-telemetered zones.  In compliance with Section 28 of the "GENERAL TERMS
             AND CONDITIONS" of this tariff, DDVCs will not apply to a non-telemetered Operational
             Zone nomination unless the zone nomination fails to reflect the nomination quantity
             calculated by the load forecasting formula or a Branchline SOL or curtailment has been
             called.


        49.  No-Notice Obligation
             --------------------
             Pursuant to Order No. 636, et seq., Northern is obligated to provide to previously
             existing firm sales customers a no-notice throughput service.  Northern will meet this
             obligation through its System Management Service (SMS).


        50.  System Balancing Agreement (SBA)
             --------------------------------

             Northern will enter into SBA agreements that provide for at least 1.35 Bcf of Peaking
             SBA and 2.94 Bcf of Pack and Draft SBA each year.  SBA's are agreements between a
             party and Northern that will provide that the SBA provider will, at Northern's
             direction, move gas to and from Northern's pipeline system by creating a positive or
             negative balance on the SBA agreement. The SBA provider may be any qualified LDC,
             producer, supplier or Shipper.  SBA fees to fulfill the overall SBA requirements will
             be as agreed to between SBA providers and Northern.
