Content

Reflects the grant of restricted stock units (RSUs) with respect to ordinary shares of the Issuer under the Issuer's Omnibus Incentive Plan (the "Plan"). The RSUs are scheduled to vest in full on the earliest of (i) the first anniversary of the date of grant, (ii) the date of the annual shareholders' meeting that next follows the grant date, or (iii) a change in control, subject to the terms of the Plan and the applicable award agreement issued thereunder.

Remarks:

This Amended Form 4 is being filed because the box indicating "no longer subject to Section 16" was inadvertently checked in the Form 4 filed earlier on March 11, 2024. The reporting person continues to be a director of the Issuer and, therefore, continues to be subject to Section 16.
