    * September 30, 2008 ratios are estimated

  ** Third quarter 2008 and second quarter 2008 net interest income declined
     $8 million and $30 million, respectively, due to tax-related non-cash
     lease income charges. Excluding these charges, the net interest margin
     would have been 3.17% and 3.10% for the three-month periods ended
     September 30, 2008, and June 30, 2008, respectively, and 3.16% for the
     nine-month period ended September 30, 2008.

  (3) Third quarter 2008 and second quarter 2008 net interest income
      declined $8 million and $30 million, respectively, and the net
      interest margin declined six basis points and 19 basis points,
      respectively, due to tax-related non-cash lease income charges.
      Excluding these charges, the net interest margin would have been 3.17%
      in the third quarter 2008 and 3.10% in the second quarter 2008.
