By written notice to the Issuer, the Fund may from time to time increase or decrease the Maximum Percentage applicable to it to any other percentage not in excess of 19.99%, provided that any such increase will not be effective until the sixty-first (61st) day after such notice is delivered to the Issuer. As a result of this restriction, the Pre-Funded Warrants are not all presently exercisable and the number of shares of Class A Ordinary Shares that may be issued upon exercise of the Pre-Funded Warrants by the above holders may change depending upon changes in the outstanding Class A Ordinary Shares.
