Item 5.  Other Events.

         In connection  with  discussions  between the  Registrant  and its bank
lender,  on January 25,  2000,  the  Registrant  raised  approximately  $500,000
through  a  private  placement  of  the  Registrant's  convertible  subordinated
debentures due January 2005 (the "Subordinated Debentures"),  which were offered
to the Registrant's  significant  shareholders  and/or  directors.  The Board of
Directors  of the  Registrant,  excluding  those  directors  who  purchased  the
Subordinated  Debentures  from  the  Registrant,   approved  the  terms  of  the
Subordinated Debentures,  including a fluctuating rate of interest (based on the
Firstar Bank prime rate plus 100 basis points) and the conversion price of $1.25
(based on a premium of 25% over the  closing  price of the  Registrant's  common
stock on January 24, 2000).  The Board  determined that such terms were fair and
represented terms no less favorable,  from the Registrant's  point of view, than
could be obtained from unaffiliated third parties.
