system and require service to be curtailed, service shall be curtailed in
reverse order of scheduling.
   
          (a)  Firm Services - Where available capacity is less than the
aggregate capacity required to satisfy all requests for firm transportation
service, whether from primary or secondary receipt points or to primary or
secondary delivery points, the following principles shall apply:
   
                (i)  The basis for allocating firm transportation capacity on a
pro rata basis through MIGC's system or any segment of MIGC's system shall be
the aggregate of volumes nominated for delivery to MIGC ("Receipt Volumes")
(less volumes to be redelivered by MIGC ("Delivery Volumes")) upstream of the
point where capacity is constrained, which are included under a firm trans-
portation agreement of a Shipper and which are nominated for shipment on any
segment of the MIGC system.
   
       The individual allocations of capacity shall be determined by dividing
the net of Receipt Volumes and Delivery Volumes, as described above, for a firm
transportation customer which is upstream of the location where capacity is
constricted, by the maximum daily quantities of all firm transportation
customers requesting service through the point where capacity is
constrained.  The resulting factor shall be multiplied by the available
capacity to determine the amount of capacity available to a particular
firm transportation customer.
   
          (b)  Interruptible Services - Notwithstanding anything to the
contrary in this Section 4.10, with respect to interruptible transportation
service:
   
               (i)  Shipper cannot increase the amount of natural gas moved
(or nominated to be moved in the event of force majeure) at any receipt or
delivery point above that amount of natural gas moved at said point the prior
day if such increase would cause the reduction of another Shipper's gas which
was moved and was scheduled to be moved the prior day;
   
               (ii)  a Shipper paying less than the applicable maximum rate
that has agreed to a lesser priority of service in the Transportation Service
Agreement will be curtailed prior to those Shippers that have not agreed to
such lesser priority.  MIGC will note on its transportation request log
those Shippers
