E X P L A N ATO RY N OT ES TO T H E R ES O LU T I O N S

The following notes give an explanation of the proposed resolutions set out in the notice of Annual General Meeting.

Resolutions 1 to 14 are proposed as ordinary resolutions meaning that for each of those resolutions to be passed, more than half the votes must be cast in favour of the resolution. Resolutions 15 to 18 are proposed as special resolutions. This means that for each of those resolutions to be passed, at least three-quarters of the votes cast must be in favour of the resolution.

ORDINARY RESOLUTIONS

RESOLUTION 1 – RECEIPT OF THE ANNUAL REPORT AND ACCOUNTS

Ordinary resolution 1 proposes the receipt and adoption of the Annual Report and Accounts, together with the reports of the Directors and the independent auditor, for the year ended 31 December 2021.

RESOLUTION 2 – RE-APPOINTMENT OF AUDITOR

The Company is required to appoint an auditor at each Annual General Meeting at which accounts are laid to hold office until the next Annual General Meeting. Ordinary resolution 2 therefore proposes that Ernst & Young LLP, the Company's existing auditor, be re-appointed as auditor to the Company until the conclusion of the Annual General Meeting in 2023 (at which the accounts for the year ending 31 December 2022 will be laid).

R ES O LU T I O N 3 – R E M U N E R AT I O N O F AU D I TO R

The Audit Committee of the Company has responsibility for overseeing the relationship with the external auditor. This responsibility includes approving the external auditor's engagement letter and the audit fee. Ordinary resolution 3 seeks shareholder approval to authorise the Audit Committee to determine the remuneration of the auditor to the Company.

RESOLUTION 4 – FINAL DIVIDEND

A final dividend of 6.7 pence per ordinary share is recommended by the Directors for payment to shareholders on the register of members of the Company at the close of business on 17 June 2022. Subject to approval by the shareholders at the AGM of ordinary resolution 4, the dividend will be paid on 8 July 2022.

RESOLUTIONS 5 TO 11 – RE-ELECTION OF DIRECTORS

The Company's Articles of Association contain powers of removal, appointment, election and re-election of Directors and provide that each Director should retire at the Annual General Meeting if they had been a Director at each of the two preceding Annual General Meetings and was not reappointed by the Company in a general meeting at or since such meeting. A retiring Director shall be eligible for re-election. Furthermore, the Company's Articles of Association provide that any Director appointed by the Board is required to submit themselves for election at the Annual General Meeting following their appointment.

The Company supports the principles of good governance as laid out in the UK Corporate Governance Code and, accordingly, all the Executive and Non-Executive Directors will retire and put themselves forward for re-election annually at each Annual General Meeting.

Ordinary resolutions 5 to 11 deal with the re-election of each Director. As described in further detail on page 99 and 100 of the 2021 Annual Report and Accounts, during 2021 the Board conducted an external evaluation of both its own effectiveness and that of its Committees. The evaluation process included the consideration of the effectiveness of each Director. In addition, the Chairman also met with each Director during the year to discuss their contribution to the Board and their personal development. These processes allow the Board to conclude that each Director makes a positive and effective contribution to the Board and demonstrates commitment to the role.

The biographies of each of the Directors can be found on pages 88 and 89 of the 2021 Annual Report and Accounts. The Board considers Divya Seshamani, Martin Sutherland, Katherine Innes Ker and Vince Niblett to be independent and there are no relationships or circumstances which are likely to affect their character or judgement.

R ES O LU T I O N 1 2 – A P P R OVA L O F R E M U N E R AT I O N C O M M I T T E E R E P O RT

Ordinary resolution 12 seeks shareholder approval for the Remuneration Committee Report (excluding the Remuneration Policy set out on pages 116 to 123 of the 2021 Annual Report and Accounts) for the year ended 31 December 2021 (which is set out on pages 112 to 135 of the 2021 Annual Report and Accounts). This vote is advisory in nature, with the consequence that if this resolution is not passed, payments made or promised to Directors will not have to be repaid, reduced or withheld. The Remuneration Policy is included in the 2021 Annual Report and Accounts for reference only, has not been amended and is not subject to a vote at this Annual General Meeting.

The Remuneration Policy was approved by shareholders at the 2020 Annual General Meeting and, unless amended, will not again be tabled for binding shareholder approval until 2023.

R ES O LU T I O N 1 3 – P O L I T I CA L D O N AT I O N S

Part 14 of the Companies Act 2006 (the 'Act'), amongst other things, prohibits the Company and its subsidiaries from making political donations or from incurring political expenditure in respect of a political party or other political organisation or an independent election candidate unless authorised by the Company's shareholders. Aggregate donations made by the Company and /or any of its subsidiaries of £5,000 or less in any 12-month period will not be covered by this prohibition. Neither the Company nor any of its subsidiaries has any intention of making any political donations or incurring any political expenditure. However, the Act defines 'political party', 'political organisation', 'political donation' and 'political expenditure' widely. For example, bodies, such as those concerned with policy review and law reform or with the representation of the business community or sections of it, which the Company and /or its subsidiaries may see benefit in supporting, may be caught. Accordingly, the Company wishes to ensure that neither it nor its subsidiaries inadvertently commits any breach of the Act through the undertaking of routine activities, which would not normally be considered to result in the making of political donations and political expenditure being incurred. As permitted under the Act, ordinary resolution 13 covers the Company and extends to all companies which are subsidiaries of the Company at any time the authority is in place. The proposed authority will expire at the conclusion of the Annual General Meeting of the Company to be held in 2023 or, if earlier, 30 June 2023.

R ES O LU T I O N 14 – R E N E WA L O F AU T H O R I T Y TO A L LOT S H A R E CA P I TA L

The Directors may only allot shares or grant rights to subscribe for, or convert any security into, shares if authorised to do so by shareholders. The previous authority granted by shareholders on 18 May 2021 in respect of the allotment of shares will expire on the holding of the 2022 AGM or, if earlier, 30 June 2022. The Directors are now seeking renewal of that authority.

Accordingly, resolution 14 will be proposed as an ordinary resolution. Part (a) of resolution 14 grants new authority to allot shares and grant rights to subscribe for, or convert any security into, shares up to an aggregate nominal amount of £751,180. This amount represents approximately onethird (33.33%) of the total issued ordinary share capital of the Company as calculated at 23 March 2022, being the latest practicable date before the publication of the notice of AGM.

In accordance with the institutional guidelines issued by the Investment Association, paragraph (b) of resolution 14 will also authorise Directors to allot, including the ordinary shares referred to in paragraph (a) of resolution 14, ordinary shares in connection with a pre-emptive offer by way of a rights issue to ordinary shareholders up to a maximum nominal amount of £1,502,360. This amount represents approximately two-thirds (66.67%) of the total issued ordinary share capital of the Company as calculated at 23 March 2022, the latest practicable date before the publication of the notice of AGM. The Directors have no present intention of exercising these authorities.

If given, these authorities will expire at the conclusion of the Annual General Meeting of the Company to be held in 2023 or, if earlier, 30 June 2023.

SPECIAL RESOLUTIONS

R ES O LU T I O N S 1 5 A N D 1 6 – AU T H O R I T I ES TO D I SA P P LY P R E- E M PT I O N R I G H TS

The Directors require a power from shareholders to allot equity securities or sell treasury shares where they propose to do so for cash and otherwise than to existing shareholders pro rata to their holdings. The previous power granted by shareholders at the Company's 2021 Annual General Meeting in respect of the disapplication of pre-emption rights will expire on the holding of the 2022 AGM or, if earlier, 30 June 2022.

Resolutions 15 and 16 will both be proposed as special resolutions. If passed, these resolutions would authorise the Directors to allot equity shares for cash without first being required to offer such shares to existing shareholders. The combined effect of both resolutions will provide authority to issue up to 10% of the issued ordinary share capital (excluding any treasury shares). Each resolution follows the guidance from the Pre-Emption Group's revised Statement of Principles, published in March 2015, and their further guidance and good practice template resolutions published in July 2016.

In accordance with this guidance, the Company confirms that it intends to use:

(a) no more than 5% of issued ordinary share capital in any one year, whether or not in connection with an acquisition or specified capital investment; and

(b) no more than an additional 5% of issued ordinary share capital in any one year, and only in connection with an acquisition or a specified capital investment.

The Directors are proposing both resolutions as they consider it prudent to maintain the flexibility the resolutions provide individually and in aggregate. The Directors do not currently intend to make use of either element of the authority, and anticipate only making use of the additional authority where the specific circumstances of the Company require. The aggregated authority contained in resolutions 15 and 16 will be limited to an aggregate nominal value of £225,354 (being 10% of the total issued ordinary share capital of the Company as calculated at 23 March 2022, being the latest practicable date before the publication of the notice of AGM).

If given, these authorities will expire at the conclusion of the Annual General Meeting of the Company to be held in 2023 or, if earlier, 30 June 2023.

The Directors will have due regard to institutional guidelines and the Statement of Principles in relation to any exercise of this authority, in particular the requirement for advance consultation with shareholders and explanation before making any non-pre-emptive cash issue pursuant to this resolution which exceeds 7.5% of the Company's issued share capital in any rolling three-year period.

RESOLUTION 17 – MARKET PURCHASE OF OWN SHARES

This resolution will give the Company authority to purchase its own shares in the market up to a limit of 10% of its issued ordinary share capital, being 22,535,411 ordinary shares as calculated at 23 March 2022, being the latest practicable date before the publication of the notice of AGM. The maximum and minimum prices are stated in the resolution. The Directors believe that it is advantageous for the Company to have the flexibility to make market purchases of its own shares and shareholders will be aware of the current buyback programme, which was announced on 26 January 2022 and which will (assuming that this resolution is passed) continue in the manner outlined in that announcement (the "Current Buyback Programme").

It is the Directors' intention only to exercise the authority to purchase the Company's shares for the purpose of employee share schemes or (as in the case of the Current Buyback Programme) where it would increase the earnings per share of those ordinary shares that are not re-purchased. This power will also only be used if the Directors consider that to do so would be in the best interests of shareholders generally. Save to the extent ordinary shares purchased are then held in treasury, any ordinary shares purchased in this way will be cancelled and the number of shares in issue will be reduced accordingly. The Company may hold in treasury any of its own ordinary shares that it purchases pursuant to the authority conferred by resolution 17. This would give the Company the ability to re-issue treasury shares quickly and cost-effectively and would provide the Company with greater flexibility in the management of its capital base. As noted in the announcement issued on 26 January 2022, the ordinary shares that are being purchased pursuant to the Current Buyback Programme are being cancelled.

As at 23 March 2022 (being the last practicable date before the publication of the notice of AGM) options to subscribe for a total of 10,644,682 ordinary shares were outstanding under the Company's employee share schemes representing 4.7% of the total issued share capital of the Company at that date and 5.2% of the issued share capital of the Company if the authority sought by resolution 17 were to be exercised in full.

Resolution 17 will be proposed as a special resolution and will expire at the conclusion of the Annual General Meeting of the Company to be held in 2023 or, if earlier, 30 June 2023.

RESOLUTION 18 – NOTICE PERIOD FOR GENERAL MEETINGS

Resolution 18 seeks to renew the authority granted at the Company's 2021 Annual General Meeting to allow the Company to hold general meetings (other than the Annual General Meeting) on 14 clear days' notice. This is in order to avoid the effect of section 307A of the Act which, without such a resolution, would have the effect of requiring the Company to give not less than 21 clear days' notice of general meetings. In order to be able to call a general meeting on less than 21 clear days' notice, the Company must make a means of electronic voting available to all shareholders for that meeting. The Company undertakes to meet the requirements for electronic voting in the Act before calling a general meeting on 14 clear days' notice. It is intended that this flexibility will only be used for non-routine business where the flexibility is merited by the business of the meeting and it is thought to be in the best interests of shareholders as a whole. If passed, the approval will be effective until the Company's Annual General Meeting to be held in 2023.

NOTES

• 1. Only holders of ordinary shares are entitled to attend and vote at this meeting. Pursuant to Regulation 41 of the Uncertificated Securities Regulations 2001, entitlement to attend and vote at the meeting and the number of votes which may be cast thereat will be determined by reference to the register of members of the Company at the close of business on Friday 20 May 2022 (or, in the event of any adjournment, at close of business on the date which is two days prior to the adjourned meeting). Changes to the register of members of the Company after the relevant deadline shall be disregarded in determining the rights of any person to attend and vote at the meeting or adjourned meeting.
• 1. A member entitled to attend and vote at the meeting may appoint one or more proxies to exercise all or any of the member's rights to attend, speak and vote at the meeting. A proxy need not be a member of the Company but must attend the meeting for the member's vote to be counted. If a member appoints more than one proxy to attend the meeting, each proxy must be appointed to exercise the rights attached to a different share or shares held by the member. If a member wishes to appoint more than one proxy they may do so at www.signalshares.com. Proxies may also be appointed electronically or through CREST. Details are given in the notes below. Appointing a proxy or any CREST proxy instruction does not preclude you from attending the Meeting and voting in person on any matters in respect of which the proxy or proxies is or are appointed but, in the event that and to the extent that you personally vote your shares, your proxy will not be entitled to vote and any vote cast by your proxy in such circumstances will be disregarded.
• 1. To be effective, the proxy vote must be submitted at www.signalshares.com so as to have been received by the Company's registrars, not less than 48 hours (excluding weekends and public holidays) before the time appointed for the meeting or any adjournment of it. Members of the Corporate Sponsored Nominee should submit their votes, so as to be received by Link Market Services Trustees (Nominees) Limited, not less than 72 hours (excluding weekends and public holidays) before the time appointed for the meeting or any adjournment of it. If you are a member of CREST, you may register the appointment of a proxy by using the CREST electronic proxy appointment service. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the Annual General Meeting and any adjournment(s) thereof by using the procedures, and to the address, described in the CREST Manual (available via www.euroclear.com/CREST) subject to the provisions of the Company's Articles of Association. CREST personal members or other CREST sponsored members, and those CREST members who have appointed a voting 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 using the CREST service to be valid, the appropriate CREST message (a "CREST Proxy Instruction") must be properly authenticated in accordance with Euroclear UK and Ireland specifications and must contain the information required for such instructions, as described in the CREST Manual. The message, regardless of whether it constitutes the appointment of a proxy or an amendment to the instruction given to a previously appointed proxy, must, in order to be valid, be transmitted so as to be received by the issuer's agent (ID: RA10) by 12.00 p.m. Friday 20 May 2022. For this purpose, the time of receipt will be taken to be the time (as determined by the time stamp applied to the message by the CREST Applications 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 provider(s) should note that Euroclear UK and Ireland does not make available special procedures in CREST for any particular messages. Normal system timings and limitations will therefore apply in relation to the input of CREST Proxy Instructions.

In this connection, CREST members and, where applicable, their CREST sponsors or voting service provider(s) 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.
