        <footnote id="F1">Represents the earned portion of a previously-granted PSU award for which the performance conditions for vesting were satisfied on April 6, 2021 based on the Company's level of achievement of specified performance goals for the period from February 1, 2019 through January 31, 2021 and the filing of the Company's Annual Report on Form 10-K for FYE 2021. Because this award was granted prior to the spin-off of Cognyte Software Ltd. by the Issuer on February 1, 2021, the number of shares underlying the award has been adjusted per the terms of the Employee Matters Agreement entered into in connection with the Company's separation transaction.</footnote>
        <footnote id="F2">The number of shares underlying unvested RSUs that were previously reported on Form 4 has been adjusted in connection with the closing of the spin-off of Cognyte Software Ltd. by the Issuer on February 1, 2021 and included in the total in Column 5.</footnote>
        <footnote id="F3">Amount sold to satisfy applicable tax withholding resulting from the vesting of previously disclosed restricted stock units vested on April 6, 2021, including those on line 1 of this Form 4.</footnote>
