26. TYPES OF DISCOUNTING
   
From time to time Shipper and Transporter may agree in writing on a level of
discount of the otherwise applicable rates and charges in addition to a
basic discount from the stated maximum rates.  For example, Transporter may
provide a specific discounted rate:
   
      (1) to certain specified quantities under the Service Agreement;
   
      (2) if specified quantity levels are actually achieved or with respect
          to quantities below a specified level;
   
      (3) to production reserves committed by the Shipper;
   
      (4) during specified time periods;
   
      (5) to specified points of receipt, points of delivery, supply areas,
          transportation paths or defined geographical areas;
   
      (6) in a specified relationship to the quantities actually transported
          (i.e. that the rates shall be adjusted in a specified relationship
          to quantities actually transported); or
   
      (7) to provide that if one rate component which was equal to or within
          the applicable maximum and minimum rate at the time the discount
          agreement was executed subsequently exceeds the applicable maximum
          rate or is below the applicable minimum rate due to a change in
          MIGC's maximum rates and/or minimum rates, so that such rate
          component must be adjusted downward or upward to equal the new
          applicable maximum or minimum rate, then other rate components may
          be adjusted upward or downward to achieve the agreed-upon overall
          rate, so long as none of the resulting rate components exceed the
          maximum rate or are below the minimum rate applicable to the rate
          component.  Such changes to rate components shall be applied
          prospectively, commencing with the date a Commission order accepts
          revised tariff sheets.  However, nothing contained herein shall be
          construed to alter a refund obligation under applicable law for
          any period during which rates which had been charged under a
          discount agreement exceeded rates which ultimately are found to be
          just and reasonable.
   
      In all circumstances the discounted rate shall be between the maximum
      rate and the minimum rate applicable to the service provided.
