        <footnote id="F1">On September 17, 2018, the Reporting Person filed a Form 4 which inadvertently described in footnotes 1 and 2 to that Form 4 that the Reporting Person sold the number of shares as indicated in column 4 of Table I, instead of purchasing such shares.  As reported in this amendment, the Reporting Person purchased such shares in multiple transactions in the open market, and the correct footnotes are reported in footnotes 2 and 3 to this amendment.</footnote>
        <footnote id="F2">This price reported in column 4 is a weighted average price.  These shares were purchased by the Reporting Person in multiple transactions in the open market at prices ranging from $11.60 to $11.70, inclusive.  The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the U.S. Securities and Exchange Commission, upon request, full information regarding the number of shares purchased at each separate price within the price range set forth in this footnote 2 to this amendment.</footnote>
