                        -----

                        A.  Firm Transportation Service:

                        The original firm Shipper shall have the option to execute a firm Service
                        Agreement which exactly matches the rate and term of the bid constituting
                        the highest economic unit value to Northern.  The highest rate that the
                        original firm shipper must match if it wishes to continue its service
                        arrangement is the maximum tariff rate.  The original firm Shipper need
                        only match the quantity bid if the quantity bid is less than the quantity
                        offered under Section 1 above.  Northern will notify the original firm
                        Shipper within five (5) work days of the best offer it must match by
                        tendering to such Shipper a Service Agreement.  The Service Agreement must
                        be executed by the original firm Shipper within fifteen (15) days of
                        Northern's tender thereof.  Northern is not required to accept an offer at
                        less than the maximum rate.

                        B.  Firm Deferred Delivery (FDD) Service:

                        The original FDD Shipper shall have the option to execute a FDD Service
                        Agreement which exactly matches the rate and term of the bid constituting
                        the highest economic unit value to Northern, subject to the following.
                        The original Shipper is not required to match the quantity offered. The
                        highest rate that the original FDD shipper must match if it wishes to
                        continue its service arrangement is the maximum tariff rate.

                        1.  Northern will notify the original FDD Shipper within five (5) work
                            days of the close of the bidding process of the various bids received
                            for its capacity.

                        2.  The original Shipper must provide written notice to Northern within
                            fifteen (15) days of the date of Northern's notification as to which
                            of the prioritized bids the original Shipper is willing to match.  The
                            original Shipper may not be required to match all bids.  In the event
                            bids received on the Shipper's capacity are for a quantity that is
                            less than the Shipper's capacity, then the original Shipper must
                            include in the notice to Northern a statement of its commitment to
                            continue service for the capacity for which there were no bids.  Such
                            notice to Northern shall be binding upon the original Shipper.

                        3.  Northern will determine the best offer(s) that the original Shipper
                            must match based on the priority provided to Northern by bidders.

                        4.  Upon tendering a Service Agreement for the best offer, such Service
                            Agreement must be executed by the original FDD Shipper within fifteen
                            (15) days.  Northern is not required to accept an offer at less than
                            the maximum rate.

                    6)  No Bids
                        -------

                        Where there are no competing bids for the capacity and the original firm
                        Shipper agrees to pay the maximum rate, service may be contracted for
                        any term the original firm Shipper chooses.  Northern is not required to
                        accept an offer at less than the maximum rate.  If Northern rejects a
                        bid at less than the maximum rate, the original Shipper may receive
                        continued service at the maximum rate unless a negotiated rate is agreed
                        to by Northern and the original Shipper.  The original firm Shipper must
                        execute the Service Agreement within fifteen (15) days of Northern's
                        tender thereof.
