- ---------------

(1) The interest component of rent expense is deemed to be approximately 25% of
    total rent expense.

(2) Preferred dividends have not been adjusted for income taxes, due to the
    composition of the taxing jurisdictions underlying the Company's operations
    and the resulting impact on the Company's effective tax rate.
