                              The Positive DDVC level for Bypassing Small Customers is as
                              follows:  if daily volumes scheduled at the delivery point are
                              less than the MDQ, the positive DDVC applies to daily volumes in
                              excess of all daily volumes scheduled at the point plus a
                              tolerance level equal to the Bypassing Small Customer's MDQ.  If
                              daily volumes scheduled at the delivery point are equal to or
                              greater than the MDQ, the Positive DDVC applies to an amount
                              equal to the Bypassing Small Customer's MDQ plus a tolerance of
                              the Bypassing Small Customer's MDQ at the point.

                          For TI
                          ------
                          1)  The Positive DDVC shall apply to the first five percent (5%) of
                              daily scheduled volumes at each delivery point which are in
                              excess of the scheduled volumes at the point plus a tolerance of
                              five percent (5%) of the scheduled volumes at the point.  The
                              tolerance for Small Customers who have not bypassed Northern's
                              system is the greater of five percent of all scheduled volumes at
                              the point or 650 MMBtu.  The tolerance level for Bypassing Small
                              Customers shall be equal to the Bypassing Small Customer's MDQ.
