        <footnote id="F1">Represents Restricted Stock Units (&quot;RSUs&quot;) awarded under the Reservoir Media, Inc. 2021 Omnibus Incentive Plan (the &quot;Plan&quot;). Each RSU represents a contingent right to receive one share of common stock, $0.0001 par value per share (the &quot;Common Stock&quot;), of Reservoir Media, Inc. (the &quot;Issuer&quot;). The RSUs will vest on July 28, 2024, subject to Reporting Person's continued service on the board of directors (the &quot;Board&quot;) of the Issuer on such date.</footnote>
        <footnote id="F2">Represents Deferred Stock Units (&quot;DSUs&quot;) awarded under the Plan. Each DSU is the economic equivalent of one share of Common Stock. The Reporting Person acquired these DSUs in connection with the Reporting Person's quarterly compensation for service as a non-employee director. The Reporting Person elected to receive payment of their quarterly compensation in DSUs in lieu of cash. The DSUs will be settled in shares of Common Stock on January 2, 2024.</footnote>
        <footnote id="F3">The number of DSUs received was calculated based on $5.35, which was the closing price of the Issuer's Common Stock on the date of grant.</footnote>
