Item 5.     Other Information

         On February 7, 2000,  the Company  issued a call for  redemption of its

Series 700 and Series 800 Warrants, which enable the holders thereof to purchase

shares of Common Stock at prices of $1.00 and $0.90 per share, respectively. The

Series 700 Warrants relate to a total of 2,583,000,  and the Series 800 Warrants

relate to a total of 2,610,000 shares of Common Stock.  The Company  anticipates

that a  substantial  number  of  Series  700 and  Series  800  Warrants  will be
