        <footnote id="F1">Represents a weighted-average price. These shares were purchased in multiple transactions at prices ranging from $18.24 to $18.25, inclusive. For all transactions reported in this Form 4 utilizing a weighted-average price, the reporting person will provide to the issuer, any security holder of the issuer, or the SEC staff, upon request, information regarding the number of shares purchased at each price within the range.</footnote>
        <footnote id="F2">The number of securities shown to be beneficially owned by the Reporting Person following the transaction being reported in this Form 4 reflects
the respective ownership of securities directly and indirectly owned. The amount of securities indirectly owned by Reporting Person was
previously combined with the amount of securities directly owned in the Forms 4 filed on May 30, 2019 and June 20, 2019, respectively, which
amounts were then also reflected in amounts of securities owned directly that were included on subsequently filed Forms 4.</footnote>
        <footnote id="F3">The amount of securities indirectly owned by Reporting Person was previously combined with the amount of securities directly owned in the Form 4 filed on August 29, 2018, which amount was then also reflected in amounts of securities owned directly that were included on subsequently filed Forms 4.</footnote>
