        <footnote id="F1">These cash-settled total return swaps were entered into by The Mangrove Partners Master Fund, Ltd. (&quot;Master Fund&quot;) with Morgan Stanley Capital Services LLC as the counterparty between August 16, 2019 and March 13, 2020 at prices between $5.44 and $12.18. The swaps can be settled and closed at any time by Master Fund.  The swaps provide Master Fund with economic exposure to the Common Stock referenced in the swap (the &quot;Subject Securities&quot;), benefiting Master Fund if the price of the Common Stock increases, and benefiting counterparty if the price of the Common Stock decreases. The swap does not provide Master Fund with the power to vote or direct the voting or dispose of, or to dispose or direct the disposition of, the Subject Securities, nor the right to acquire such power over the Subject Securities. The Reporting Persons expressly disclaim beneficial ownership of the Subject Securities.</footnote>
        <footnote id="F2">Master Fund, Mangrove Partners, the investment manager of Master Fund, and Nathaniel H. August, the principal of Mangrove Partners, may be deemed to indirectly beneficially own the securities reported herein and disclaims beneficial ownership of these securities, except to the extent of its or his pecuniary interest therein, if any.</footnote>
