                         GENERAL TERMS AND CONDITIONS


         4.   Flow Orders.  Northern needs the ability to call on volumes to flow at Carlton.
              The following operational requirements apply during the months of November
              through March for each year that the Carlton Resolution is in effect to the
              Carlton Supplier/Shippers, Sourcers and the Other Carlton Shippers Entitlement as
              applicable.

              An operational flow order is an order issued to alleviate conditions, inter alia,
              which threaten or could threaten the safe operations or system integrity, of the
              transportation service provider's system or to maintain operations required to
              provide efficient and reliable firm service.  Whenever a Transportation Service
              Provider experiences these conditions, any pertinent order should be referred to
              as an Operational Flow Order.
