This conversion rate is subject to adjustment as described in “Description of the Notes -Adjustment to Conversion Rate” above. As a result, the number of shares of Common Stock issuable upon conversion of the Notes may increase or decrease in the future.

In calculating this amount for each securityholder, we treated as outstanding the number of shares of common stock issuable upon conversion of that securityholder’s Notes, but we did not assume conversion of any other securityholder’s Notes.
 
(4)   For purposes of computing the number and percentage of Notes and shares of common stock to be held by the selling securityholders after the conclusion of the offering, we have assumed for purposes of this table above that the selling securityholders named above will sell all of their Notes and all of the common stock issuable upon conversion of their Notes offered by this prospectus, and that any other shares of our Common Stock beneficially owned by these selling securityholders will continue to be beneficially owned.
