        <footnote id="F1">This Amendment to Form 4 does not report a new transaction.  This Amendment is being filed solely to correct an inadvertent mathematical error in the sum reported for the Amount of Securities Beneficially Owned following the transactions previously reported in the original Form 4 filed on April 6, 2022.</footnote>
        <footnote id="F2">Each performance right represented a contingent right to receive one share of the issuer's common stock at vesting.  The performance rights vested at a rate between 0% and 200% during a three-year performance cycle ending on March 31, 2022 based on the issuer's relative total shareholder return performance among the Russell 2000 Index over the performance cycle. The performance rights, along with accrued dividend equivalent units, vested at 200% of the target award amount and were settled in shares of common stock pursuant to the award agreement terms.</footnote>
