          may be deemed to  beneficially  own the shares of Common  Stock deemed
          beneficially owned by TIC and TPT. Mr. Jones expressly  disclaims such
          beneficial ownership. Because Mr. Pallotta is the portfolio manager of
          TIC and TPT responsible  for investment  decisions with respect to the
          shares of Common Stock reported herein,  Mr. Pallotta may be deemed to
          beneficially own the shares of Common Stock deemed  beneficially owned
          by TIC and TPT.  Mr.  Pallotta  expressly  disclaims  such  beneficial
          ownership.
