         thousandths percent (18.259%) of the outstanding common shares of

         iii      having discussions with Cincinnati Bell Inc. regarding the
                  possibility of Cincinnati Bell Inc. taking a larger position
                  in e-Net, Inc. or ZeroPlus Inc. at a future date.
