        <footnote id="F1">Each PSU represents a contingent right to receive one share of the Issuer's Common Stock. The number of PSUs earned and issuable upon vesting will be determined based on goals set by the Compensation Committee (the &quot;Compensation Committee&quot;) of the Issuer's Board of Directors on an annual basis for each of the three fiscal years prior to the vesting date.</footnote>
        <footnote id="F2">The Compensation Committee determined that the 2020 pre-bonus adjusted EBITDA (50% weighting) and Revenue (50% weighting) metrics resulted in a combined 125% level of the target awards being earned for the 2020 financial performance period, subject to no material changes in connection with the finalization of the audit and the filing of the Issuer's Annual Report on Form 10-K for the year ended December 31, 2020 (the &quot;2020 Form 10-K&quot;). The 2020 Form 10-K was filed with the U.S. Securities and Exchange Commission on February 26, 2021. As a result, Mr. Macken earned 22,884 shares, pending his continued employment with the Issuer through the vesting date (third anniversary of the date of grant).</footnote>
