Remarks:

Note: This Amendment No. 1 to Form 3 is being filed to correct the number of shares owned by the reporting person as of January 24, 2023. The number of shares has been increased by 9,000 shares that the reporting person had received prior to such date upon exercise of an employee stock option (which option was not listed in Table II of the original Form 3) and decreased by 1,270.1939 shares that the reporting person holds in the Issuer's Employee Stock Purchase Plan and that were inadvertently double counted in the original Form 3. In addition, Table II is corrected herein to indicate that tranches of options expiring on December 12, 2027, December 11, 2028 and December 9, 2029 that were shown in the original Form 3 as not yet vested in fact vested on December 31, 2021. *Executive Vice President and Global Head of Private Banking & Wealth Management, SEI
