        <footnote id="F1">To further align director interests with shareholders and to conserve cash in light of the impact of the COVID-19 pandemic, the Board of Directors of Twin River Worldwide Holdings, Inc. (the &quot;Company&quot;) determined in March 2020 to pay the cash portion of the non-employee director annual retainer in shares of Company common stock instead of cash while the majority of operations were shut down. Accordingly, on May 14 2020, the reporting person received a number of fully-vested Company shares equal to the cash portion of the reporting person's quarterly cash retainer divided by the closing price per share of Company common stock on May 13, 2020, which resulted in a grant of 1,999 shares of Company common stock.</footnote>
