       ** State and federal payroll/withholding taxes are paid by a payroll
          service provider. At the end of the month we accrue for payroll which
          has not yet been paid. This accrual is included as part of the above
          gross payroll expense total. We do not show any post petition taxes
          still owing on these accruals as the taxes will not be due until the
          payroll is actually paid. This accrued payroll was dated and paid on

        **  State and federal payroll/withholding taxes are paid by a payroll
            service provider. At the end of the month we accrue for payroll
            which has not yet been paid. This accrual is included as part of the
            above gross payroll expense total. We do not show any post petition
            taxes still owing on these accruals as the taxes will not be due
            until the payroll is actually paid. This accrued payroll was dated
            and paid on 4/5/00.
