TRANSPORTATION GENERAL TERMS AND CONDITIONS
                              (Continued)
   
                (4) Confirming Party's nightly processing and routine
maintenance occurring outside of normal business hours are apt to interrupt
the normal schedule for confirmations/quick response turnaround stated in
Standards Board Standard 1.3.45.  Such delays should be kept to a minimum.
The normal schedule should be resumed at the earliest opportunity and no
later than the start of normal working hours the following day, seven days
per week (Standards Board Standard 1.3.46).
   
       (b) Intra-day Nominations are subject to the following conditions:
   
                (1) Intra-day Nominations may only be submitted for
points at which MIGC has sufficient measurement, telemetry and control to
allow MIGC to verify flow and at which a change in volume delivered to Shipper
can be implemented immediately by a corresponding Receipt Point volume change.
Subject to the foregoing, Intra-day Nominations can be used to request
increases or decreases in total flow, changes to receipt points, or changes
to delivery points scheduled gas.
   
                (2) Valid Intra-day Nominations shall be processed
in the order received.  Such nominations shall reflect the revised total
volumes that Shipper desires to be received and delivered during that Day.
All nominations, including Intra-day Nominations shall be based on a daily
quantity, thus an intra-day nominator need not submit an hourly nomination.
Intra-day nominations shall include an effective date and time.  The
interconnected parties shall agree on the hourly flows of the intra-day
nominations, if not otherwise addressed in MIGC's Service Agreement or tariff.
Such nomination shall not automatically rollover to the next Day, but shall
be effective only for the Day submitted.
   
                (3) For services that provide for Intra-day
Nominations and scheduling, there is no limitation as to the number of
Intra-day Nominations (Line items as per Standards Board Standard 1.2.1) which
a Shipper may submit at any one standard Nomination cycle or in total across
all standard Nomination cycles (Standards Board Standard 1.3.32).
