        <footnote id="F1">Restricted Stock Units (RSUs) granted under The Allstate Corporation 2017 Equity Compensation Plan for Non-Employee Directors providing that each RSU represents the right to receive one share of Allstate common stock following either a standard restriction period or a deferred period of restriction if elected.  The RSUs reported will convert into common stock on the tenth anniversary of the date of grant, except in the event of the reporting person's death or disability, which will cause the RSUs to convert on the day following the date of death or disability.</footnote>
        <footnote id="F2">Clerical error resulted in reporting person's original Form 4 incorrectly reporting the number of RSUs granted as 1,726. The correct number of RSUs granted was 1,783.</footnote>
