(1)  2001 income before income taxes does not include an extraordinary item or
     cumulative effect of accounting change. 1998 income before income taxes
     does not include a cumulative effect of accounting change.

    "Earnings" consist of income before income taxes and fixed charges, less
     dividends on preferred securities subject to mandatory redemption. "Fixed
     charges" consist of interest cost, including interest on deposits,
     dividends on preferred securities subject to mandatory redemption, and that
     portion of rent expense estimated to be representative of the interest
     factor. The preferred stock dividend amounts represent pre-tax earnings
     required to cover dividends on preferred stock.
