1. If you wish, you can register your proxy appointment online at www.shareview.co.uk, where full details of the procedure are given. You will need to create an online portfolio using your Shareholder Reference Number ('SRN') shown on this proxy form. Once logged in, simply click "View" on the "My Investments" page and follow the on-screen instructions. Please read the terms and conditions very carefully. If you return both paper and electronic voting instructions then, in the absence of other evidence, those received last by our registrar, Equiniti Limited, will take precedence.

2. CREST members should please refer to the Notice of Meeting for instructions regarding CREST electronic proxy appointment services.

3. If you wish to register your proxy appointment in paper form, please comply with the following notes – your proxy card may be invalid if your instructions are not clear:

(a) You may wish to delete the words "Chair of the Meeting" and insert the name of a proxy of your choice in the box, who need not be a member but must attend the meeting in person to represent you. Please initial any alteration.

If the proxy is being appointed in relation to less than your full voting entitlement, please enter in the box next to the proxy holder's name the number of shares in relation to which they are authorised to act as your proxy. If left blank your proxy will be deemed to be authorised in respect of your full voting entitlement (or if this proxy form has been issued in respect of a designated account for a shareholder, the full voting entitlement for that designated account).

(b) To appoint more than one proxy, additional proxy forms may be obtained by contacting our registrar, Equiniti Limited, on +44 (0)371 384 2967* (please use the country code if calling from overseas) or you may copy this form. Please indicate in the box next to the proxy holder's name the number of shares in relation to which the proxy is authorised to act as your proxy (please note that each proxy must be appointed to exercise the rights attaching to different shares held by you). Please also indicate, by ticking the box provided, if the proxy appointment is one of multiple appointments made. All forms must be signed and should be returned together in the same envelope.

(c) The Form of Proxy and, if relevant, the power of attorney or other authority under which it is signed, or a certified copy of that power or authority, must be received by our registrar, Equiniti Limited, by 10.00am on Tuesday, 7 July 2026.

(d) If the member is a corporation, the Form of Proxy must be executed either under seal or in any other manner having the same effect or under the hand of an officer or the person duly authorised in writing stating their capacity (e.g. Director, Secretary, duly authorised attorney).

(e) For joint holders, the signature of any one of them will suffice. The instructions of the joint holder whose name appears first on the register of members in respect of the joint holding will be accepted to the exclusion of those of the other joint holders.

(f) The address shown overleaf is that appearing in the register of members. The Form of Proxy and attendance card are not transferable.

1. To be entitled to vote at the Meeting (and for the purpose of determining the number of votes that may be cast), shareholders' names must be entered in the register of members at 6.30pm on Tuesday, 7 July 2026 (or, if the Meeting is adjourned, at 6.30pm on the day which is two working days prior to the date fixed for the adjourned meeting).
