Item 5.  Other Events.

         By supplements to Prospectus dated April 12, 2000, the Company reported
sales of its Common Stock pursuant to a Registration Statement on Form S-3 (SEC
No. 333-33966). Such prospectus supplements indicated the number of shares sold,
the price per share, and the net proceeds to the Company.

         The net proceeds indicated in some of these supplements did not reflect
additional expenses incurred by Ladenburg Thalmann & Co., the selling agent, in
connection with such sales and reimbursed by the Company. Accordingly, we are
hereby reporting the actual net proceeds from these sales, after giving effect
to the additional expenses:

         (i)      Prospectus Supplement dated July 11, 2000, actual net proceeds
                  $8,536,000

         (ii)     Prospectus Supplement dated July 12, 2000, actual net proceeds
                  $3,750,665

         (iii)    Prospectus Supplement dated July 19, 2000, actual net proceeds
                  $3,695,237
