(1) For purposes of computing the ratio of earnings to fixed charges, earnings
    represents income before income taxes and fixed charges. Fixed charges
    represent interest expense and preferred stock dividends, which dividends
    commenced in October 1996. Deposits include interest-bearing deposits and
    repurchase agreements. Without including preferred stock dividends in fixed
    charges and excluding interest on deposits, the ratio of earnings to fixed
    charges for the six months ended June 30, 1997 and the year ended December
    31, 1996 were 5.89x and 9.91x, respectively. Without including preferred
    stock dividends in fixed charges and including interest on deposits, the
    ratio of earnings to fixed charges for the six months ended June 30, 1997
    and the year ended December 31, 1996 were 1.61x and 1.68x, respectively.
