Notes:

Where used in this Notice the expressions "American Depositary Receipt" or "ADR" means an American depositary receipt evidencing one or more American depositary share(s), each of which in turn represents four shares.

Any member entitled to attend and vote at this meeting may appoint a proxy who need not be a member of the Company to attend, speak and vote in his/her place. Completion of the enclosed form of proxy will not affect the right of a member to attend and vote at this meeting in person.

To be valid, forms of proxy duly signed together with the power of attorney or such other authority under which they are signed (or certified copy of such power or authority), must be lodged with Computershare Investor Services Ireland, 3100 Lake Drive, Citywest Business Campus, Dublin 24, D24 AK82, Ireland, not later than September 27, 2023 at 10:00am (or in the case of an adjournment, 48 hours before the time appointed for the holding of the meeting).

The record date for the annual general meeting is September 1, 2023. Only those shareholders on the register of members and holders of ADRs at close of business on that date are entitled to vote at the annual general meeting or at any adjournment or postponement thereof.

ADR holders may instruct the ADR depositary, The Bank of New York Mellon (BNY), as to the way in which the shares represented by their ADRs should be voted by completing and returning the voting card provided by BNY in accordance with the instructions delivered by BNY to ADR holders.

Voting on each of the resolutions will be decided on a poll. This means that shareholders who do not attend the annual general meeting in person but have validly submitted a form of proxy will have their votes taken into account according to the number of shares they hold.

All references to time in this Notice are to Irish Standard Time (as set out in the Standard Time Act 1968 and the Standard Time (Amendment) Act 1971).

The proxy appointed shall not vote or attempt to exercise the right to vote attached to the shares, other than in accordance with instructions set out in this form of proxy.
