        <footnote id="F1">Each share of Series B Cumulative Convertible Preferred Stock (the &quot;Series B Stock&quot;) is convertible at the option of Lyles United, LLC (&quot;Lyles&quot;) into that number of shares of the issuer's Common Stock equal to: (i) $19.50, divided by (ii) the conversion price in effect at the time of conversion.  The conversion price of the Series B Stock is currently fixed at $6.3316226, but is subject to certain anti-dilution adjustments as set forth in the Certificate of Designations, Powers, Preferences and Rights of the Series B Stock (the &quot;Certificate of Designations&quot;).
