        <footnote id="F1">Marc J. Leder (&quot;Leder&quot;) and Rodger R. Krouse (&quot;Krouse&quot;) each currently serve as a director of the Issuer.  In addition, Leder and Krouse each own 50% of the membership interests in Sun Capital Partners, LLC (&quot;Sun Partners LLC&quot;), which in turn is the general partner of Sun Capital Advisors II, LP (&quot;Sun Advisors II&quot;), which in turn is the general partner of Sun Capital Partners II, LP (&quot;Sun Partners II LP&quot;).  Sun Partners II LP owns all of the membership interests in Sun Solunet, LLC (&quot;Sun Solunet&quot;).  As a result, Leder, Krouse, Sun Partners LLC, Sun Advisors II and Sun Partners II LP may be deemed to have indirect beneficial ownership of the 729.3712335 shares of Series B Convertible Preferred Stock and the Common Stock obtained as a result of the conversion.</footnote>
        <footnote id="F2">Leder, Krouse, Sun Partners LLC, Sun Advisors II and Sun Partners II LP each expressly disclaims beneficial ownership of any shares of Common Stock in which they do not have a pecuniary interest.</footnote>
        <footnote id="F3">Each share of Series B Convertible Preferred Stock was automatically converted into 50,000 fully-paid and nonassesable shares of Common Stock immediately upon the effectiveness of an amendment to the Issuer's Articles of Incorporation which had the effect of increasing the number of shares of Common Stock that the Issuer is authorized to issue to a number sufficient to provide for the issuance of shares of Common Stock upon conversion of all of the then outstanding shares of Series B Convertible Preferred Stock.  Such amendment was effective on April 13, 2004.</footnote>
