                  The Agency Commission Matrix shown below shall be used to
                  calculate the commissions due Agency for the customers
                  provided to PowerSource. This matrix provides the commission
                  rate, in cents/kWh, to be applied to the aggregated electric
                  load of customers on a monthly basis to determine the
                  commission due Agency. This Matrix provides the following
                  values for these rates based on the type of customer
                  (Residential or Commercial) and the tenure of the agreement of
                  that customer from its inception.
