(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.
