(B) CDI Holders

(a) EUI and CREST International service for proxy voting

I. A CDI Holder cannot give voting instructions directly to the Company. A CDI Holder must instead give their voting instructions directly to their CREST Account Holder. Their CREST Account Holder will in turn cast their votes via the Euroclear & International Limited ("EUI") and CREST International service for proxy voting (which is provided by Broadridge Financial Solutions Limited ("Broadridge").

II. Further details in relation to the Broadridge voting service can accessed on the EUI "My Euroclear" website (https://my.euroclear.com) and further details on instructions for voting can be found under "All you need to know about SRD II in Euroclear UK & International – Euroclear".

IV. Sending voting instructions to your CREST Account Holder

(a) A CDI Holder should consult with their CREST Account Holder at the earliest opportunity for further information on the processes and timelines for submitting their votes for the Shareholders' General Meeting. In particular, the CDI Holder will need to contact their CREST Account Holder for details of:

(i) The means of communication which can be used to send their voting instructions to them; and
(ii) The latest deadline (date and time) to lodge their voting instructions with them

(b) It is also important to note that the voting deadline of the CREST International service for proxy voting provided by Broadridge is

expected to be at least two business days prior to the Company's proxy appointment deadline. However, the CDI Holder should confirm the precise Broadridge voting deadline with its CREST Account Holder (in addition to checking what its CREST Account Holder's own deadline is for receiving voting instructions). Voting instructions cannot be changed or cancelled after Broadridge's voting deadline.

V. Broadridge Global Voting service for CREST Account Holders and brokers holding CDI interests for clients in CREST

(a) EUI, the operator of CREST, has arranged for voting instructions relating to the CDIs held in CREST to be received via Broadridge, a third-party service provider. Your CREST Account Holders and brokers holding CDI interests for clients in CREST will be required to make use of the EUI proxy voting service facilitated by Broadridge Global Proxy Voting service, in order to receive meeting announcements and send back voting instructions.

(b) For client set-up, they will need to complete the Meetings and Voting Set-up Form (CRT408), a copy of which is available on the Euroclear Bank website (www.euroclear.com) which is accessible to CREST participants. Completed application forms should be returned to EUI by an authorised signatory with another relevant authorised signatory copied for verification purposes using the following email address: UK-membership@euroclear.com.

(c) Fully completed and returned application forms will be shared with Broadridge by EUI. This will enable Broadridge to contact the applicant and share further detailed information on the service offering and initiate the process for granting the applicant access to the Broadridge platform.

(d) The above process is to be completed only for the set-up. Once a CREST Account Holder has access to the Broadridge platform, they can complete and submit proxy appointments (including voting instructions) electronically. Broadridge will process and deliver proxy voting instructions received by the Broadridge voting deadline date. Alternatively, Broadridge may provide a facility for CREST Account Holders to send a third-party proxy voting instructions through the Broadridge platform to appoint a third party (who may be a corporate representative of the CDI holder themselves) to attend and vote at the Shareholders' General Meeting for the number of ordinary shares specified in the proxy instruction (subject to the Broadridge voting deadline).

(e) CREST Account Holders or brokers holding CDI interest for clients in CREST are strongly encouraged to familiarise themselves with the arrangements with Broadridge, including the voting deadlines and procedures and to take, as soon as possible, any further actions required by Broadridge before they can avail themselves of this voting service.

(b) Attending the Shareholders' General Meeting in person

I. A CDI Holder cannot give voting instructions directly to the Company and must give their voting instructions directly to their CREST Account Holder only. If, however, the CDI Holder wishes to attend the Shareholders' General Meeting and cast their votes in person, then the CDI Holder needs to liaise with its banker or broker ahead of the Shareholders' General Meeting to request that an admission card be issued to the CDI Holder.

II. If the CDI Holder has not received an admission card before the Shareholders' General Meeting, the CDI Holder will need to present at the Shareholders' General Meeting:

(a) a certificate of participation issued by the banker or broker who holds the CREST Account in which the CDIs are registered; and
(b) a valid identification document.

(c) Transfer by CDI Holders of their CDIs prior to the Shareholders' General Meeting

Limitations on the exercise of voting or attendance rights may apply in respect of CDI trades which are expected to settle after the Broadridge voting deadline but before the Company's record date. The CDI Holder should therefore consult with their CREST Account Holder at the earliest opportunity for further information on the requirements, processes, and timelines for submitting their votes (and on their eligibility to submit such votes) for the Shareholders' General Meeting.
