Limited 2025 Omnibus Incentive Compensation Plan. The RSUs vest in five equal installments with (i) the first installment vesting on March 22, 2027, (ii) the second installment vesting on March 15,
2028, (iii) the third installment vesting on March 15, 2029, (iv) the fourth installment vesting on March 15, 2030 and (v) the fifth installment vesting on March 15, 2031. Notwithstanding the foregoing,
as a result of Ms. O'Connell becoming retirement eligible on August 12, 2025, the RSUs vested in full on the grant date, with settlement to occur in accordance with the ordinary vesting schedule. Each RSU
represents a contingent right to receive one ordinary share, no par value, of the Company (&quot;Ordinary Share&quot;).</footnote>
