(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.
