                    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 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 the 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.

                        Flexibility.  Shippers may request to amend their agreements to add,
                        change, or delete primary firm receipt points as limited by the firm
                        throughput service agreement as discussed above.  Approval of such
                        request will be subject to capacity availability and operational
                        considerations.  All receipt points on the system will be available for
                        use as alternate firm receipt points within the area provided by the
                        contract and subject to operational considerations.

                        No geographical limitations will be placed on the availability of
                        amended receipt points within the service area provided by the
                        contract.

                        Other than the discount provision below, there will be no reservation
                        fee impact if receipt points are moved solely within the Market Area or
                        moved solely within the Field Area.

                        Discounts.  Any discount granted (reservation or commodity) at a primary
                        receipt point will not be automatically granted at an amended or
                        alternate receipt point.

                    b)  Receipt Point Allocation

                        Allocation of capacity is pursuant to Section 26 of the GENERAL TERMS
                        AND CONDITIONS of this tariff.
