ITEM 5. OTHER EVENTS.

         On September 18, 2002, we announced the simultaneous closing of two
financing transactions pursuant to which we received $16,000,000 in gross cash
proceeds. In the first transaction, we issued the following:

   o  819,886 shares of Series A Convertible Preferred Stock, par value $1.00
      per share;

   o  1,304,815 shares of Series B Convertible Preferred Stock, par value $1.00
      per share; and

   o  warrants to purchase 709,528 shares of our common stock, par value $.01
      per share.

         In the second transaction, we issued:

   o  6.5% Secured Convertible Notes, in a principal amount of $8,000,000; and

   o  warrants to purchase 386,473 shares of our common stock.

         Because our common stock is listed on the Nasdaq National Market, we
are subject to Marketplace Rule 4350. Marketplace Rule 4350 requires us to
obtain the approval of our shareholders before issuing our common stock at a
price below the greater of our book price or the market price of our common
stock to our officers or directors, or where the number of shares of common
stock issuable is equal to or greater than 20% of our outstanding common stock.

         Accordingly, on January 15, 2003, we held a special meeting of
shareholders to consider and vote upon a proposal to approve the issuance of our
common stock at a price below the greater of the book or market value of our
common stock, as of September 16, 2002, (1) to officers and directors of our
company and other holders of our Series A Convertible Preferred Stock upon
conversion or redemption of our Series A Convertible Preferred Stock and (2) in
an amount equal to or greater than 20% of our outstanding common stock
(immediately prior to the issuance of these securities) upon the conversion,
redemption and/or exercise, as applicable, of our Series A Convertible Preferred
Stock, Series B Convertible Preferred Stock, 6.5% Secured Convertible Notes and
the warrants associated with the 6.5% Secured Convertible Notes, in both cases,
to comply with (A) our agreements with purchasers of the Series A Convertible
Preferred Stock, the Series B Convertible Preferred Stock, and the 6.5% Secured
Convertible Notes and (B) Marketplace Rule 4350 of the Nasdaq National Market.

         More information about these financing transactions and the special
shareholders meeting are contained in a Proxy Statement we filed with the
Securities Exchange Commission on November 25, 2002.

         Our shareholders approved the proposal, according to the following
vote:

         FOR                       AGAINST                    ABSTAIN

         9,409,359                 107,509                    506,819
