This Lock-Up Agreement shall automatically terminate and the undersigned shall be released from all of his, her or its obligations hereunder upon the earlier of (i) the date on which the Registration Statement filed with the SEC with respect to the Offering is withdrawn, (ii) the date on which for any reason the Underwriting Agreement is terminated (other than the provisions thereof that survive termination) prior to payment for and delivery of the Shares to be sold thereunder, (iii) the date on which the Selling Shareholders representing a majority of the ADSs to be sold by all Selling Shareholders notify the Underwriter, in writing and prior to the execution of the Underwriting Agreement, that they do not intend to proceed with the Offering and (iv) June 25, 2025 in the event that the Underwriting Agreement has not been executed by such date.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement.
