(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.
