        <footnote id="F2">Grant of RSUs, each of which represents a contingent right to receive one share of common stock of QMCO. The RSUs vest in full on the earlier of October 1, 2025 or the date of the
Company's next annual stockholder meeting, subject to continued service on the Company's Board of Directors, Delayed filing arose from an error related to effecting the reverse stock split within QMCOs stock plan administration platform and the resulting delay of the distribution of the equity award agreement to reporting person.  Reporting person has elected to continue to use the grant date for the reported transaction date notwithstanding the delayed distribution of the equity award agreement.</footnote>
