        <footnote id="F1">The original filing erroneously reported these 6,258 shares as being beneficially owned directly by the Reporting Person. This filing amends the information in columns 6 and 7 of Table I to reflect that these shares are indirectly beneficially owned by the Reporting Person through a trust. Column 5 of Table I has also been amended to reflect the correct amount of securities beneficially owned indirectly by the Reporting Person through the trust following the reported transaction.</footnote>
        <footnote id="F2">The price reported in Column 4 is a weighted average price. These shares were purchased in multiple transactions at prices ranging from $24.34 to $24.37 inclusive. The reporting person undertakes to provide Simmons First National Corporation (&quot;Simmons&quot;), any security holder of Simmons, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares purchased at each separate price within the range set forth in this footnote.</footnote>
