Preferred Stock

After the completion of this offering, no shares of preferred stock will be outstanding, assuming the automatic conversion of all outstanding shares of our convertible preferred stock into 72,500,750 shares of common stock effective immediately prior to the completion of this offering, including the conversion of all of our outstanding shares of Series A, Series B, Series C redeemable and Series D redeemable convertible preferred stock. Pursuant to our amended and restated certificate of incorporation to be effective immediately prior to the completion of this offering, our board of directors will have the authority, without further action by the stockholders, to issue from time to time up to two hundred million shares of preferred stock in one or more series. Our board of directors may designate the rights, preferences, privileges and restrictions of the preferred stock, including dividend rights, conversion rights, voting rights, redemption rights, liquidation preference, sinking fund terms and the number of shares constituting any series or the designation of any series. The issuance of preferred stock could have the effect of restricting dividends on the common stock, diluting the voting power of the common stock, impairing the liquidation rights of the common stock or delaying, deterring or preventing a change in control. Such issuance could have the effect of decreasing the market price of the common stock. We currently have no plans to issue any shares of preferred stock.
