        <footnote id="F1">On January 3, 2005, the reporting peson contributed 93,000 shares of M&amp;T Bank Corporation common stock to a Grantor Retained Annuity Trust of which the reporting person is trustee and of which the reporting peson and his descendants are beneficiaries.  The reporting person continues to report beneficial ownership of all of the M&amp;T Bank Corporation common stock held by the GRAT but disclaims beneficial ownership except to the extent of his pecuniary interest therein.</footnote>
        <footnote id="F2">The information reported is as of September 30, 2006.</footnote>
    </footnotes>

    <remarks>This is the third of three Form 4 filings by the reporting person to report the reporting person's transactions that occurred on November 28, 2006 and November 29, 2006.  Multiple Form 4 filings are required due to SEC system limitations that do not allow more than 30 transactions to be reported in Table I.</remarks>
