FERC Gas Tariff                                                                           Superseding
Fifth Revised Volume No. 1                                    Substitute Second Revised Sheet No. 298

                               GENERAL TERMS AND CONDITIONS

                        Failure by the Shipper to give Northern the notice specified in this
                        section will result in the automatic abandonment of the entitlement and
                        the Shipper's right to the subject capacity at the end of the contract
                        term will cease.  Shipper may waive its right to participate in the
                        Right of First Refusal process which will result in automatic
                        abandonment of the entitlement upon the termination of the contract.

                    2)  Bidding Process
                        ---------------

                        Subsequent to Northern's receipt of the Shipper's Right of First
                        Refusal notice described in Section 1) above, Northern will post the
                        designated capacity on its website in order to solicit bids for the
                        capacity.  Northern will post any availability of throughput capacity
                        under Right of First Refusal as separate and distinct from generally
                        available throughput capacity.  However, Northern may post any
                        availability of Firm Deferred Delivery (FDD) capacity, including FDD
                        capacity available under Right of First Refusal, in a single aggregate
                        posting with the type of capacity identified, e.g., generally available
                        or Right of First Refusal.

                        A Bidder desiring to obtain the posted capacity must submit a bid to
                        Northern, in accordance with Section 3) below, within
                        forty-five (45) days of the posting to participate in the Right of
                        First Refusal process.

                        If the tendered bids are less than maximum rate and if Northern is
                        willing to accept less than maximum rates, Northern will utilize an
                        iterative bidding process.  Each bid will be posted on the website and
                        each iteration's best offer will be posted on the website for
                        informational purposes, along with the name of the highest bidder.  In
                        subsequent iteration(s), bidders will have five (5) days to respond to
                        Northern after a posting; thereafter, after each bidding period,
                        Northern will have up to five (5) business days to perform an analysis
                        to determine the best offer as described in Section 4) below.  The
                        bidding process must be completed three (3) months before the end of
                        the existing contract term.

                        If any bid submitted by a bidder is subsequently withdrawn, any new
                        bids submitted by such bidder for the same capacity or path(s) must be
                        at a higher rate.

                        Northern will have the right to reject, on a non-discriminatory basis,
                        any bid not at the maximum rate.

                    3)  Contents of Bid
                        ---------------

                        Service Agreements, corresponding to the Shipper's bid, will be
                        required and must contain the price, term, amount of capacity desired
                        and primary receipt and delivery points.

                        When any Shipper bids the maximum rate, such Shipper is only required
                        to bid up to the maximum rate for its requested receipt and delivery
                        points, not the maximum rate which may apply to different receipt and
                        delivery points which could be charged for such service.

                        Multiple bids for transportation capacity, defined as different bids
                        made for different portions of the total capacity, will be permitted.

                        Bidders for FDD capacity may submit bids on one or more packages of FDD
                        capacity; provided, however, bidders may submit only one bid per
                        package.  In the event that bidder submits bids on more than one FDD
                        package, then bidder must prioritize its bids and indicate a minimum
                        and maximum total cycle quantity desired.
