FERC Gas Tariff
Fifth Revised Volume No. 1

                                      GENERAL TERMS AND CONDITIONS

                   Charge Adjustment ("A.C.A.").  Such  A.C.A. increment or unit charge
                   shall be identical to that determined by the FERC and assessed against
                   Northern.  Such charge will be revised if and to the extent the
                   assessment against Northern is revised.

                   Filing Procedure.  Northern shall file the revised A.C.A. unit charge
                   at least thirty (30) days prior to the effective date (which FERC
                   Order No. 472 indicates will normally be October 1) and effectuate
                   such rate adjustment unless, for good cause shown, a different
                   effective date is allowed by valid Commission Order.

              37.  CHANGE IN MDQ
                   -------------

                   The MDQ shall be specified in the Throughput Service Agreement.
                   Shipper may increase the MDQ (or the Total Aggregate MDQ if under a TF
                   Agreement) under the Throughput Service Agreement only if Shipper is
                   allocated receipt and delivery point capacity.
