          1.  AVAILABILITY
              ------------

              This Rate Schedule is available to the Market Area Small Customers with
              daily firm entitlement of 5,500 Mcf or less for the firm transportation of gas
              that received service pursuant to Northern's Rate Schedule GS on May 18, 1992
              (Grandfathered, as shown on Sheet No. 510), whether such gas is purchased from
              a third party supplier or under Rate Schedule SF, pursuant to a firm GS-T
              Throughput Service Agreement by Northern under the following terms and
              conditions:

              a)  Shipper has executed a Firm GS-T Throughput Service Agreement ("GS-T
                  Agreement") in the form contained in Northern's FERC Gas Tariff;

              b)  The throughput service shall be subject to all of the terms and
                  conditions contained in this Rate Schedule and the "General Terms and
                  Conditions" of this Tariff;

              c)  Shippers under this GS-T Rate Schedule must utilize the GS-T firm
                  entitlement at the designated TBS delivery point(s) as of May 18, 1992 or
                  delivery points for that same community.  The GS-T service must be fully
                  utilized prior to any TI services for that GS-T Shipper or any party as
                  agent for the GS-T Shipper.  TF firm entitlement may be utilized prior to
                  GS-T.

              d)  Shipper who has a GS-T Agreement shall also be eligible to purchase
                  SMS, Northern's no-notice throughput service.

              e)  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.

          2.  RATE
              ----

              Separately stated GS-T Market Area and GS-T Field Area rates, as shown on
              Sheet No. 53 of this Tariff, shall apply in accordance with the GS-T
              Shipper's agreement(s) described in 1 above.

              In addition, the GS-T Shipper shall pay the daily delivery variance charge,
              overrun charges, out-of-balance charges, penalties, surcharges, and any other
              applicable charges as set forth in this Tariff.

          3.  TERM OF GS-T AGREEMENT
              ----------------------

              GS-T Agreements entered into with GS customers shall retain any unilateral
              rollover right (grandfathered rollover right) contained therein or contained in
              a GS customer's existing TF agreements.  However, should a Shipper request a
              rollover of an agreement which contains grandfathered rollover rights for less
              than the term of the original GS-T agreement, or a rollover at less than
              maximum rates, then the MDQ shall be subject to the Right of First Refusal
              process described in Section 52 of The GENERAL TERMS AND CONDITIONS of this
              Tariff.  If a Shipper under an agreement containing a grandfathered rollover
              right requests a rollover of less than the MDQ, then only that portion of the
              agreement for which a rollover was requested will remain subject to the
              grandfathered rollover right.  The remaining quantity shall be subject to the
              Right of First Refusal process.
