        <footnote id="F1">Piton Capital Partners LLC, a Delaware limited liability company (&quot;Piton&quot;) and family client of Kokino LLC (&quot;Kokino&quot;), also reports beneficial ownership of the Issuer's common stock pursuant to Rule 13d-1 of the Securities Exchange Act of 1934, as amended, pursuant to a Schedule 13D filed by Piton with the SEC on March 22, 2018, as amended on April 6, 2018, April 25, 2018, November 6, 2018 and November 21, 2019.</footnote>
        <footnote id="F2">Indicates shares of the Issuer's common stock (&quot;Shares&quot;) beneficially owned by Piton.  Piton's managing member is Piton Capital Management LLC (&quot;PCM&quot;). PCM's managing member is Kokino, and Kokino is Piton's trading manager. Robert Averick, who is currently a director of the Issuer and an employee of Kokino, manages Piton's investment in the Issuer as a portfolio manager of Kokino. Mr. Averick holds an economic interest in Piton (which interest may be held directly and, from time to time, indirectly through PCM). Also, Mr. Averick's incentive compensation/allocation as Piton's portfolio manager, which is calculated in Kokino's discretion, may be based, among other things, on the performance of Shares held by Piton. Such amount may be paid in cash and/or by way of increasing Mr. Averick's minority interest in Piton (either directly or indirectly through PCM).</footnote>
        <footnote id="F3">The price reported in Column 4 is a weighted average price rounded to the nearest hundredth. These shares were purchased in multiple transactions at prices ranging from $4.975 to $5.00. Mr. Averick undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the SEC, upon request, full information regarding the number of Shares purchased at each separate price within the ranges set forth in footnote (3) to this Form 4.</footnote>
