Notes

1. To be entitled to attend and vote at the General Meeting (and for the purpose of the determination by the Company of the number of votes they may cast), shareholders must be registered in the Register of Members of the Company at close of trading on 6 June 2023. Changes to the Register of Members after the relevant deadline shall be disregarded in determining the rights of any person to attend and vote at the General Meeting.

• A member who is entitled to attend and vote at the General Meeting is entitled to appoint another person as a proxy to exercise all or part of their rights to attend and to speak and vote on their behalf at the General Meeting. Shareholders are encouraged to appoint the Chair of the General Meeting as his or her proxy, irrespective of whether or not they propose to attend the General Meeting in person. If a Shareholder appoints the Chair of the General Meeting as his or her proxy, the Chair will vote in accordance with the Shareholders instructions. Appointing a proxy will not prevent a member from attending and voting in person. A proxy need not be a shareholder of the Company.

• In the case of joint holders, where more than one of the joint holders' purports to appoint a proxy, only the appointment submitted by the most senior holder will be accepted. Seniority is determined by the order in which the names of the joint holders appear in the Company's Register of Members in respect of the joint holding (the first named being the most senior).

• A vote withheld is not a vote in law, which means that the vote will not be counted in the calculation of votes for or against the resolution. If no voting indication is given, your proxy will vote or abstain from voting at his or her discretion. Your proxy will vote (or abstain from voting) as he or she thinks fit in relation to any other matter which is put before the General Meeting.

• You can vote either:
• 1. by logging on to www.signalshares.com and following the instructions;
  2. If you are an institutional investor you may also be able to appoint a proxy electronically via the Proxymity platform, a process which has been agreed by the Company and approved by the Registrar. For further information regarding Proxymity, please go to www.proxymity.io. Your proxy must be lodged by 10:00am on 6 June 2023 in order to be considered valid or, if the meeting is adjourned, by the time which is 48 hours before the time of the adjourned meeting. Before you can appoint a proxy via this process you will need to have agreed to Proxymity's associated terms and conditions. It is important that you read these carefully as you will be bound by them and they will govern the electronic appointment of your proxy. An electronic proxy appointment via the Proxymity platform may be revoked completely by sending an authenticated message via the platform instructing the removal of your proxy vote.

(c) you may request a hard copy form of proxy directly from the Company's Registrars, Link Market Services Limited on Tel:.+44 (0)371 664 0300; Calls are charged at the standard geographic rate and will vary by provider. Calls from outside the United Kingdom will be charged at the applicable international rate. Lines are open 9.00 a.m. - 5.30 p.m. (London time), Monday to Friday (excluding public holidays in England and Wales); or

(d) in the case of CREST members, by utilising the CREST electronic proxy appointment service in accordance with the procedures set out below.

• If you return more than one proxy appointment, either by paper or electronic communication, the appointment received last by the Registrar before the latest time for the receipt of proxies will take precedence. You are advised to read the terms and conditions of use carefully. Electronic communication facilities are open to all shareholders and those who use them will not be disadvantaged.

• CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the General Meeting (and any adjournment of the General Meeting) by using the procedures described in the CREST Manual (available from www.euroclear.com). CREST Personal Members or other CREST sponsored members, and those CREST members who have appointed a service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate action on their behalf.

• In order for a proxy appointment or instruction made by means of CREST to be valid, the appropriate CREST message (a 'CREST Proxy Instruction') must be properly authenticated in accordance with Euroclear UK & International Limited's specifications and must contain the information required for such instructions, as described in the CREST Manual. The message must be transmitted so as to be received by the issuer's agent (ID RA10) by 10.00 a.m. on 6 June 2023 . For this purpose, the time of receipt will be taken to mean the time (as determined by the timestamp applied to the message by the CREST application host) from which the issuer's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time, any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.

• CREST members and, where applicable, their CREST sponsors or voting service providers should note that Euroclear UK & International Limited does not make available special procedures in CREST for any particular message. Normal system timings and limitations will, therefore, apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member, or sponsored member, or has appointed a voting service provider(s), to procure that his CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members and, where applicable, their CREST sponsors or voting system providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings. The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.

1. Any corporation which is a shareholder may authorise such person as it thinks fit to act as its representative at this meeting. Any person so authorised shall be entitled to exercise on behalf of the corporation which he/ she represents the same powers (other than to appoint a proxy) as that corporation could exercise if it were an individual shareholder (provided, in the case of multiple corporate representatives of the same corporate shareholder, they are appointed in respect of different shares owned by the corporate shareholder or, if they are appointed in respect of the same shares, they vote the shares in the same way). To be able to attend and vote at the General Meeting, corporate representatives will be required to produce prior to their entry to the Meeting evidence satisfactory to the Company of their appointment.
2. As at 22 May 2023 (being the latest practicable business day prior to the publication of this Notice), the Company's ordinary issued share capital consists of 26,014,946 ordinary shares, carrying one vote each. The Company holds no ordinary shares in treasury. Therefore, the total voting rights in the Company as at 22 May 2023 are 26,014,946.
