Ratio of earnings to combined fixed charges and

(a)  Preferred stock dividend requirements are adjusted to represent a pretax
     earnings equivalent

(b)  Income before income taxes for the year ended December 31, 1996, includes
     a charge of $54.3 million related to the launch of the MBNA Platinum Plus
     MasterCard and Visa program. Without the charge, the ratio of earnings to
     combined fixed charges and preferred stock dividend requirements,
     including and excluding interest on deposits, would have been 1.98 and
     4.02, respectively.

(c)  Income before income taxes for 1993 includes a charge of $150.0 million
     for the termination of a marketing agreement with an independent
     third-party marketing organization. Without the charge, the ratio of
     earnings to combined fixed charges and preferred stock dividend
     requirements, including and excluding interest on deposits, would have
     been 2.85 and 9.92, respectively.

The ratio of earnings to combined fixed charges and preferred stock dividend
requirements is computed by dividing (i) income before income taxes and fixed
charges less interest capitalized during such period, net of amortization of
previously capitalized interest, by (ii) fixed charges and preferred stock
dividend requirements. Fixed charges consist of interest expense on borrowings,
including capitalized interest (including or excluding deposits, as the case
may be), and the portion of rental expense which is deemed representative of
interest. The preferred stock dividend requirements represent the pretax
earnings which would have been required to cover such dividend requirements on
the Corporation's preferred stock outstanding. The Corporation did not have any
preferred stock outstanding during the periods prior to 1995 presented above
and accordingly there were no preferred stock dividend requirements during such
periods.
