                                GENERAL TERMS AND CONDITIONS

                    Northern shall electronically initiate the confirmation process.  At the end of
                    each gas day, Northern should provide the final scheduled quantities for the
                    just completed gas day.  With respect to the implementation of this process via
                    the 1.4.x scheduled quantity related standards, Northern should send an end of
                    gas day Scheduled Quantity document.  Receivers of the end of gas day Scheduled
                    Quantity document can waive the sender's sending of the end of gas day
                    Scheduled Quantity document.

                    The sending party shall adhere to nomination, confirmation, and scheduling
                    deadlines.  The receiving party has the right to waive the deadlines.

                    Shipper shall deliver, or cause to be delivered, to Northern at the Point(s) of
                    receipt on a uniform daily and hourly basis that quantity of natural gas
                    that has been scheduled for transportation.

               INTRADAY NOMINATIONS
               --------------------

               An intraday nomination is a nomination electronically submitted after the nomination
               deadline whose effective time is no earlier than the beginning of
               the gas day and runs through the end of that gas day.  The Evening, Intraday 1 and
               Intraday 2 Nomination Cycles constitute Northern's standard Intraday nomination
               opportunities.  For services that provide for intraday nominations and scheduling,
               there is no limitation as to the number of intraday nominations which a service
               requester may submit at any one standard nomination cycle or in total across all
               standard nomination cycles.  Intraday nominations can be used to request increases
               or decreases in total flow, changes to receipt points, or changes in delivery points
               of scheduled gas.  Intraday nominations may be used to nominate new market or
               supply.  Intraday nominations do not roll over and are applicable to one (1)
               day only and must include an effective time.  All nominations, including
               intraday nominations, will be based on a daily quantity; thus, an intraday
               nominator need not submit an hourly nomination.  Intraday nominations will
               include an effective date and time.  The interconnected parties will agree on
               the hourly flows of the intraday nomination.  Intraday nominations do not
               replace the remainder of standing nominations.  There is no need to re-nominate if
               intraday nomination modifies existing nomination.

               Firm intraday nominations are entitled to bump scheduled interruptible service only
               during the Evening and Intraday 1 Nomination cycles.  Northern will provide notice
               of the applicability and types of penalties to be effective the following gas day
               for any bumped volumes on its website by 3:00 p.m. prior to the gas day.  During
               non-critical periods, daily penalties will be waived for bumped volumes on the date
               of the bump. Northern will provide a separate notice of bumping in the same manner
               in which Northern provides notice of operational flow orders.  Northern will provide
               notification of bumped volumes through the scheduled quantities statement.  Northern
               will also electronically communicate notice directly to bumped Shipper's in
               accordance with the grid-wide timeline for scheduled quantities.  Northern shall
               provide affected parties with notification of bumping through the Shipper's choice
               of Electronic Notice Delivery Mechanism.  Unless the affected party and Northern
               have agreed to exclusive notification via EDI/EDM, the affected party should provide
               Northern with at least one Internet E-mail address to be used for Electronic Notice
               Delivery of notification of bumping.  The obligation of Northern to provide
               notification is waived until the above requirement has been met.  Northern will
               support the concurrent sending of electronic notification of bumping to two Internet
               E-mail addresses for each affected party.  Affected parties will manage internal
               distribution of notices received by Electronic Notice Delivery.  Penalties related
               to the bumped volume will be waived if notice has not been provided.
