        <footnote id="F1">A performance grant of Restricted Stock Units (RSUs), which is convertible into common stock of the Company on a one-for-one basis, was approved by the Company's Compensation Committee on October 28, 2019 (the &quot;Performance Grant&quot;), subject to the Performance Criteria described in footnote 2, and described in the Company's definitive proxy statements filed in 2020, 2021 and 2022.  On May 2, 2022, the Company's Compensation Committee deemed the Performance Criteria satisfied.  In addition to the Performance Criteria, the RSUs were subject to annual time vesting on September 1, 2020, September 1, 2021 and September 1, 2022.  As a result, the reporting person was issued 66,667 shares of common stock on May 2, 2022 and 33,333 RSUs remain unvested (as described in footnote 5).</footnote>
        <footnote id="F2">The Performance Criteria shall be for any fiscal quarter in which the RSUs are outstanding, such RSU shall not vest unless and until the Company has (i) gross revenue determined in accordance with the Company's reviewed or audited financial statements in excess of $12.5 million for such fiscal quarter and positive adjusted EBITDA of at least $2.0 million, and (ii) the recipient continues to provide services to the Company either as an employee, director or consultant on the last day of the quarter that the performance criteria is met.  In the event of a change of control, all RSUs which have not vested on the date of such change of control shall immediately vest even if the Performance Criteria have not been met.</footnote>
        <footnote id="F3">Includes 20,000 RSUs originally granted on November 20, 2020, convertible into common stock of the issuer on a one-for-one basis, which vest in two equal installments on each of November 1, 2022, and November 1, 2023, subject to accelerated vesting under certain conditions.</footnote>
        <footnote id="F4">Includes 32,500 RSUs originally granted on September 24, 2021, convertible into common stock of the issuer on a one-for-one basis, which vest in three equal installments on each of October 1, 2022, October 1, 2023 and October 1, 2024, subject to accelerated vesting under certain conditions.</footnote>
        <footnote id="F5">Includes 33,333 RSUs originally granted on October 28, 2019, convertible into common stock of the issuer on a one-for-one basis, which vests on September 1, 2022, subject to accelerated vesting under certain conditions.</footnote>
