        <footnote id="F1">For 2017, the reporting person agreed to take 100% of his cash bonus in shares of restricted stock with an eight-year restriction period.  Because the reporting person elected to take his bonus for 2017 in shares of restricted stock, the Company awarded the reporting person additional compensation, in restricted stock, equal to his cash bonus.  The price of the securities acquired by the reporting person is based on the average price of the Company's common stock for the 10 trading days immediately preceding August 28, 2017, which was $25.18.  The number of securities issued is equal to the total cash bonus, including the additional compensation, divided by such price.</footnote>
        <footnote id="F2">The amount shown represents the beneficial ownership of the Company's securities by Athena Funding Partners, LLC (&quot;AFP&quot;).  The reporting person owns 99% of AFP and disclaims beneficial ownership of the securities to the extent it exceeds his pecuniary interest therein and the inclusion of the shares in this report shall not be deemed to be an admission of  beneficial ownership of the reported shares for the purposes of Section 16 to the Exchange Act or otherwise.</footnote>
