        <footnote id="F1">Shares withheld for taxes upon the settlement in shares of restricted stock units previously granted to the reporting person.</footnote>
        <footnote id="F2">The reported transaction involves an award of restricted stock units under the M&amp;T Bank Corporation 2009 Equity Incentive Compensation Plan. Each restricted stock unit represents a contingent right to receive one share of M&amp;T Bank Corporation common stock upon vesting.</footnote>
        <footnote id="F3">The restricted stock unit award includes a total of 6,102 shares. 1,830 shares of the restricted stock unit award will vest on January 29, 2012; an additional 1,831 shares will vest on January 29, 2013; and the remaining 2,441 shares will vest on January 29, 2014.  The restricted stock unit award may also be subject to restrictions on transfer upon settlement.  For more information, please see the Current Report on Form 8-K filed by M&amp;T Bank Corporation on January 25, 2010.</footnote>
        <footnote id="F4">The restricted stock units were granted under an incentive compensation plan maintained by M&amp;T Bank Corporation, and therefore the reporting person paid no price for the restricted stock units.</footnote>
