5. Resolution 11: To re-appoint the auditor
The Company is required to appoint an auditor at each general meeting at which accounts are laid before the Company, to hold office
until the conclusion of the next such meeting.
The Audit and Risk Committee has reviewed the effectiveness, independence and objectivity of the external auditor, BDO LLP, on
behalf of the Board, who, following the recommendation of the Audit and Risk Committee, proposes that BDO LLP be re-appointed
as auditor of the Company. The Audit and Risk Committee has confirmed to the Board that its recommendation is free from third party
influence and that no restrictive contractual provisions have been imposed on the Company limiting the choice of auditor.

6. Resolution 12: To authorise the Audit and Risk Committee to agree the auditor’s remuneration
This Resolution authorises the Audit and Risk Committee of the Board, in accordance with standard practice, to negotiate and agree
the remuneration of the auditor.

7. Resolution 13: Political donations and expenditure
The Act prohibits companies from making political donations to UK political organisations or independent candidates, or incurring UK
political expenditure, unless authorised by shareholders in advance.
The Company does not make, and does not intend to make, donations to political organisations or independent election candidates,
nor does it incur or intend to incur any political expenditure within the ordinary meaning of those words. It is the Company’s policy not
to make political donations and the Company has no intention of altering this policy. However, the definitions of political donations,political organisations and political expenditure used in the Act are very wide. For example, bodies such as those concerned with
policy review or reform, or those representing the business community and special interest groups which the Company and/or its
subsidiaries may see benefit in supporting, or activities which are an accepted part of engaging with stakeholders to ensure mattersaffecting the Group's operations are considered and addressed, but which would not ordinarily be considered as political donations orpolitical expenditure, might be caught.
In common with many other listed companies, the Board considers it prudent to seek shareholder authority to make political
donations and to incur political expenditure not exceeding £50,000 in total, to ensure that the Group does not inadvertently breach thelegislation. As permitted under the Act, the Resolution covers the Company and extends to all subsidiaries of the Company at any time
the authority is in place. If given, this authority will expire at the AGM in 2023 or on 30 September 2023, whichever is earlier.

as an ordinary resolution to grant new authorities to allot shares and grant rights to subscribe for, or convert any security into, shares.
If given, these authorities will expire at the AGM in 2023 or on 30 September 2023, whichever is the earlier.

representing approximately one-third of the Company’s existing issued share capital calculated as at 30 May 2022, being the latest
practicable date prior to the publication of this notice.

This amount represents (before any reduction)
approximately two-thirds of the Company’s existing issued share capital calculated as at 30 May 2022.
The Directors have no present intention to exercise this authority. However, if they do exercise the authority, the Directors intend tofollow best practice as regards the use of such authority as recommended by the Investment Association. As at the date of this notice,
the Company does not hold any shares in treasury.

9. Resolution 15: Disapplication of pre-emption rights
Your Directors require a power from shareholders to allot equity securities or sell treasury shares for cash otherwise than to existing
shareholders pro rata to their holdings. The power granted at the last AGM is due to expire at this year’s AGM. Accordingly, Resolution
15 will be proposed as a special resolution to grant such a power.
Apart from offers or invitations in proportion to the respective number of shares held, the power will be limited to the allotment ofequity securities and sales of treasury shares for cash up to an aggregate nominal value of £144,153 (being approximately 5% of
the Company’s issued ordinary share capital at 30 May 2022, being the latest practicable date prior to the publication of this notice).
If given, this power will expire at the conclusion of the AGM in 2023 or on 30 September 2023, whichever is the earlier.
The figure of 5% reflects the Pre-Emption Group 2015 Statement of Principles for the disapplication of pre-emption rights (the“Statement of Principles”). Your Directors will have due regard to the Statement of Principles in relation to any exercise of this power, inparticular they do not intend to allot shares for cash on a non-pre-emptive basis pursuant to this power in excess of an amount equal
to 7.5% of the total issued ordinary share capital of the Company in any rolling three-year period, without prior consultation withshareholders. This limit excludes any ordinary shares issues pursuant to a general disapplication of pre-emption rights in connection
with an acquisition or specified capital investment contemplated by Resolution 16.

10. Resolution 16: Additional disapplication of pre-emption rights
Your Directors are seeking a further power from shareholders to allot equity securities or sell treasury shares for cash otherwise than
to existing shareholders pro rata to their holdings, to reflect the Statement of Principles. The same power granted at the last AGM isdue to expire at this year’s AGM. Accordingly, Resolution 16 will be proposed as a special resolution to grant such a power. The power
will be limited to the allotment of equity securities and sales of treasury shares for cash up to an aggregate nominal value of £144,153(being approximately 5% of the Company’s issued ordinary share capital at 30 May 2022, being the latest practicable date prior to the
publication of this notice). This is in addition to the 5% referred to in Resolution 15. If given, this power will expire at the conclusion of the
AGM in 2023 or on 30 September 2023, whichever is the earlier. Your Directors will have due regard to the Statement of Principles inrelation to any exercise of this power and in particular they confirm that they intend to use this power only in connection with atransaction which they have determined to be an acquisition or other capital investment (of a kind contemplated by the Statement of
Principles most recently published prior to the date of this notice) which is announced contemporaneously with the announcement of
the issue, or which has taken place in the preceding six month period and is disclosed in the announcement of the issue.

Explanatory notes to the proposed resolutions continued

11. Resolution 17: Authority to purchase own shares
Resolution 17 will be proposed as a special resolution and 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. The maximum and minimum prices are stated in the Resolution. Your Directors
believe that it is advantageous for the Company to have this flexibility to make market purchases of its own shares. Your Directors will
exercise this authority only if they are satisfied that a purchase would be in the interests of the Company and its shareholders
generally and where the Directors (a) expect that such a purchase would result in an increase in earnings per share, (b) consider that
the Company has excess cash, and/or (c) determine that it is appropriate to increase the Company's gearing. If given, this authority will
expire at the conclusion of the AGM in 2023 or 30 September 2023, whichever is the earlier.
In the event that shares are purchased, they would either be cancelled (and the number of shares in issue would be reduced
accordingly) or, in accordance with the Act, be retained as treasury shares. The Directors believe that the ability to hold purchased
shares as treasury shares would give the Company the ability to transfer treasury shares quickly and cost effectively and would
provide the Company with additional flexibility in the management of its capital base. Treasury shares may subsequently becancelled, sold for cash or used to satisfy options and awards granted to employees pursuant to the Company's share option
schemes. Once held in treasury, the Company is not entitled to exercise any rights, including the right to attend and vote at meetings,
in respect of the shares. Further, no dividend or other distribution of the Company's assets may be made to the Company in respect of
the treasury shares.
As at 30 May 2022 (being the latest practicable date prior to the publication of this notice), the total number of options over sharesthat were outstanding under all of the Company’s share option plans was 877,898, which if exercised would represent 1.5% of theissued share capital of the Company at that date. If the Company were to purchase its own shares to the fullest possible extent of its
authority from shareholders (existing and being sought), this number of outstanding options could potentially represent 1.7% of theissued share capital of the Company.

12. Resolution 18: Notice of general meetings
The Act requires the notice period for general meetings of the Company to be at least 21 clear days unless shareholders approve a
shorter notice period, which cannot however be less than 14 clear days. AGMs will continue to be held on at least 21 clear days’ notice.
Resolution 18 will be proposed as a special resolution to obtain the necessary shareholder approval for that shorter notice period.
The approval will be effective until the Company’s next AGM, when it is intended that a similar resolution will be proposed.
The flexibility offered by this Resolution will be used where, taking into account the circumstances, the Directors consider thisappropriate in relation to the business to be considered at the meeting. Please note that in accordance with the Act, in order to beable to call a general meeting on less than 21 clear days’ notice, the Company will make a means of electronic voting available toall shareholders for that meeting.

Notes to the Notice of AGM

The following notes explain your general rights as a shareholder and your right to attend and vote at this AGM or to appoint someone
else to vote on your behalf.
1)

a person may cast), shareholders must be registered in the Register of Members of the Company at close of business on
26 July 2022 or, in the event of any adjournment, at close of business on the date which is two days before the day of the
adjourned meeting (ignoring non-working days). Changes to the Company's Register of Members after the relevant deadline
shall be disregarded in determining the rights of any person to attend and vote at the AGM.

2) Shareholders are entitled to appoint another person as a proxy to exercise all or any of their rights to attend and to speak andvote on their behalf at the AGM. A shareholder may appoint more than one proxy in relation to the AGM provided that each proxyis appointed to exercise the rights attached to a different ordinary share or ordinary shares held by that shareholder. A proxy neednot be a shareholder of the Company. You are encouraged to appoint the chair of the meeting as your proxy as this will ensure thatyour votes are cast in accordance with your wishes at the AGM if neither you nor any other person you might appoint as your proxyis able to attend the AGM in person.
3) A vote withheld is not a vote under English law, which means that the vote will not be counted in the calculation of votes for oragainst 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 AGM.
4) 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).
5) You can register proxy appointments and voting instructions using one of the following methods:•

by logging on to www.signalshares.com and selecting the “Proxy Voting” link. If you have not previously registered, you will
first be asked to register as a new user, for which you will require your investor code (which can be found on your sharecertificate or dividend confirmation statement), family name and postcode (if resident in the UK);•by completing and returning a hard copy proxy form by post or by hand to Link Group, PXS 1, Central Square, 10th Floor,

Subject to any Covid-19 related restrictions in place at the time of the AGM, completion of a form of proxy, or other instrument
appointing a proxy, or any CREST Proxy Instruction will not preclude a member attending and voting in person at the meeting if he/she wishes to do so.
6) If you return more than one proxy appointment, either by paper or electronic communication, the appointment received last by theRegistrar before the latest time for the receipt of proxies will take precedence. Electronic communication facilities are open to allshareholders and those who use them will not be disadvantaged.

Proxy Instruction’) must be properly authenticated in accordance with Euroclear UK & International Limited’s specifications andmust contain the information required for such instructions, as described in the CREST Manual. In order to be valid, the message
must be transmitted so as to be received by the issuer’s agent (ID RA10) by no later than 11am on 26 July 2022. For this purpose,
the time of receipt will be taken to mean the time (as determined by the time stamp 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.
9) 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 thata 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 service provider(s) are referred, inparticular, 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.

If a Nominated Person has no suchproxy appointment right or does not wish to exercise it, he/she may have a right, under such an agreement, to give instructions
to the member as to the exercise of voting rights.
The statement of the above rights of the members in relation to the appointment of proxies does not apply to Nominated Persons.
Those rights can only be exercised by members of the Company.
11) Any corporation which is a shareholder can appoint one or more corporate representatives who may exercise on its behalf
all of its powers as a shareholder provided that no more than one corporate representative exercises powers in relation to
