Explanation of Responses:
(1)	Represents the number of shares required to be sold by the reporting person to cover tax withholding obligations in connection with the vesting of the Restricted Share Units vested on February 27, 2021. This sale is mandated by the issuer's award agreement under its equity incentive plans to require the satisfaction of tax withholding obligations to be funded by a "sell to cover" transaction and does not represent a discretionary trade by the reporting person.
(2)	Represents restricted share units that are scheduled to vest in equal installments on each of March 2, 2022, 2023 and 2024, subject to the reporting person's continued employment through such dates.
(3)	Options to buy 16,003 ordinary shares will vest and become exercisable in equal installments on each of March 2, 2022, 2023, 2024 and 2025, subject to the reporting person's continued employment through such dates.
