Item 6 of the Statement is hereby amended and supplemented as follows: Pre-Funded Warrants Each Pre-Funded Warrant has an exercise price of $0.0001 per share of Common stock, is immediately exercisable and does not expire. Under the terms of the Pre-Funded Warrants, the Issuer may not effect the exercise of any Pre-Funded Warrant, and the RTW Funds will not be entitled to exercise any portion of any Pre-Funded Warrant, which, upon giving effect to such exercise, would cause the RTW Funds, together with their Attribution Parties (as defined in the Pre-Funded Warrants) to own more than 9.99% (the "Maximum Percentage") of the number of shares of the Common stock outstanding immediately after giving effect to such exercise, as such percentage ownership is determined in accordance with Section 13(d) of the Exchange Act. By written notice to the Issuer, the RTW Funds may from time to time increase or decrease the Maximum Percentage to any other percentage not in excess of 19.99% specified in such notice; provided that any increase in the Maximum Percentage will not be effective until the sixty-first (61st) day after such notice is delivered to the Issuer and shall not negatively affect any partial exercise effected prior to such change. By virtue of this provision, the Pre-Funded Warrants are not presently exercisable within sixth days and, accordingly the shares underlying the Pre-Funded Warrants are not presently considered beneficially owned by the Reporting Persons for purposes of Section 13(d) of the Exchange Act. The exercise price and the number of shares of Common stock issuable upon exercise of each Pre-Funded Warrant are subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Common stock. In the event of certain fundamental transactions (as described in the Pre-Funded Warrants), a holder of Pre Funded Warrants will be entitled to receive, upon exercise of the Pre-Funded Warrants, the kind and amount of securities, cash or property that such holder would have received had they exercised in full the Pre-Funded Warrants immediately prior to such fundamental transaction without regard to any limitations on exercise contained in the Pre Funded Warrants. References to and the description of the Pre-Funded Warrants set forth above in this Item 6 do not purport to be complete and are qualified in their entirety by reference to the full text of the Form of Pre-Funded Warrant, which is attached hereto as Exhibit 99.1 and incorporated by reference herein.
