These sales are mandated by the Issuer's election under its equity incentive plan to require the satisfaction of a tax withholding obligation to be funded by a &quot;sell to cover&quot; transaction and do not represent discretionary trades by the Reporting Person.</footnote>
        <footnote id="F4">The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $0.69 to $0.74, inclusive.
