(1)  For purposes of computing the consolidated ratios of earnings to fixed
     charges, earnings represent income before income taxes plus fixed charges.
     Fixed charges, excluding interest on deposits, include interest (other than
     on deposits), whether expensed or capitalized, and that portion of rental
     expense (generally one third) deemed representative of the interest factor.
     Fixed charges, including interest on deposits, consist of the foregoing
     items plus interest on deposits.
