        <footnote id="F1">Restricted stock units (&quot;RSUs&quot;) convert into HYMC Class A Common Stock (the &quot;Common Stock&quot;) on a one-for-one basis.</footnote>
        <footnote id="F2">On February 20, 2019, $102,500 of RSUs were granted to Mr. Stieber which vest pro rata in equal installments on each of May 29, 2020, February 19, 2021 and February 18, 2022. The number of shares of Common Stock that the RSUs convert into is based upon the Common Stock price on each vesting date. Vested RSUs convert into Common Stock on each applicable vesting date, provided that, if on the applicable vesting date, the holder is prohibited from trading under HYMC's policies or pursuant to applicable securities laws,  the conversion date will be the 2nd trading day after the date such prohibitions no longer apply.  On May 20, 2021, the first tranche of RSUs converted into 3,309 shares of Common Stock and the second tranche converted into 4,874 shares of Common Stock.</footnote>
        <footnote id="F3">The number of RSUs remaining will be determined based upon the Common Stock price on February 18, 2022, the third tranche vesting date.</footnote>
