(1)  The stated amounts,  to the extent they describe common stock issuable upon
     conversion of the holder's preferred stock, assume conversion of all of the
     holders'  preferred  stock at a  conversion  ratio of 6.4935  shares of our
     common stock per share of preferred stock. This conversion ratio,  however,
     will be  subject to  adjustment  as  described  under  "Description  of the
     Preferred Stock - Conversion Price Adjustment".  As a result, the number of
     shares of our common stock issuable upon  conversion of the preferred stock
     and, therefore, attributable to holders of preferred stock, may increase or
     decrease in the future.
