Payments commence following the reporting person's departure from the Board of Directors of SunTrust Banks, Inc.  These phantom stock units convert to common stock on a one-for-one basis.</footnote>
        <footnote id="F2">This amendment corrects the July 6, 2006 filing which incorrectly reported the reporting person's Phantom Stock as 3,712.1060.  The corrected amount, 3,741.4678,  includes additional shares acquired as a result of reinvestment of dividends since the reporting person's last filing.</footnote>
