Dear Shareholder

THE 2018 ANNUAL GENERAL MEETING

I am pleased to be writing to you with details of our 2018 Annual General Meeting which we are holding at the offices of Addleshaw Goddard LLP, Milton Gate, 60 Chiswell Street, London EC1Y 4AG at 10.30am on Friday 11 May 2018.

Our Chief Executive Officer, Pete Raby, will give a presentation on the Group's business and performance over the last 12 months, together with an overview of the Group's strategy. Shareholders will then have the opportunity to ask questions before moving onto the formal business of the Annual General Meeting.

Notice of the Annual General Meeting can be found on pages 2 and 3 of this document and contains the resolutions dealing with the business of the meeting. The Explanatory notes for all business of the Annual General Meeting are given on pages 4 to 6 of this document.

Only holders of Ordinary shares or their proxies or duly authorised representatives may vote at the Annual General Meeting.

All your votes are important to us and, once again this year, you will be asked to vote on each of the resolutions on a poll, as permitted by the Articles of Association. This is in line with practice adopted by many UK public companies, primarily as a result of the complexities of the law around voting on a show of hands. It also means that the voting results will be a more representative reflection of the views of our shareholder base.

Action to be taken

You are requested (whether or not you intend to be present at the meeting) to complete and submit a proxy form in accordance with the Notes to the Notice of the Annual General Meeting set out on pages 6 and 7. To be valid, the proxy form must be received at the address for delivery specified in the Notes by 10.30am on Wednesday 9 May 2018. Completion and return of a proxy form will not preclude a shareholder from attending and voting at the meeting.

Recommendation

Your Directors consider that all the resolutions to be put to the meeting will promote the success of the Company and are in the best interests of the Company and its shareholders as a whole, and accordingly, unanimously recommend you to vote in favour of them as they intend to do so in respect of their own beneficial shareholdings (other than in respect of resolutions in which they hold an interest).

Thank you for your continued support.

Yours faithfully

ANDREW SHILSTON CHAIRMAN

and shall expire on the revocation or expiry (unless renewed) of the authority conferred on the Directors by resolution 14 in the notice of this meeting, save that, before the expiry of this power, the Company may make any offer or agreement which would or might require equity securities to be allotted after such expiry and the Directors may allot equity securities under any such offer or agreement as if the power had not expired.

EXPLANATORY NOTES TO THE BUSINESS OF THE ANNUAL GENERAL MEETING

Resolution 1 – Receipt of the Annual Report and Accounts

The Companies Act 2006 requires the directors of a public company to lay before the company in general meeting copies of the directors' reports, the independent auditor's report and the audited accounts of the company in respect of each financial year. In accordance with the UK Corporate Governance Code, the Company proposes a resolution on its audited accounts and reports for the financial year ended 31 December 2017 ('the 2017 Annual Report and Accounts').

Resolution 2 – Approval of the Directors' Remuneration Report

In accordance with the Companies Act 2006, shareholders are invited to approve the Directors' Remuneration Report for the financial year ended 31 December 2017.

The Directors' Remuneration Report is set out on pages 70 to 89 of the 2017 Annual Report and Accounts. For the purposes of this resolution, the Directors' Remuneration Report does not include the Directors' Remuneration Policy which is set out on pages 72 to 79 of the 2017 Annual Report and Accounts. The vote on this resolution is advisory only and the Directors' entitlement to remuneration is not conditional on its being passed.

The Companies Act 2006 requires the Directors' Remuneration Policy to be put to shareholders for approval annually unless the approved policy remains unchanged, in which case it need only be put to shareholders for approval at least every three years. The Company is not proposing any changes to the Directors' Remuneration Policy approved at the Annual General Meeting in 2016.

Resolution 3 – Final dividend

The Directors are recommending the payment of a final dividend of 7.0 pence per share on the Ordinary shares in respect of the year ended 31 December 2017 which, if approved, will be payable on 25 May 2018 to shareholders on the register at the close of business on 4 May 2018. The Company is not offering a scrip alternative to the cash dividend.

Resolutions 4 to 10 – Election/Re-election of Directors

In accordance with the Company's Articles of Association and the provisions of the UK Corporate Governance Code, Jane Aikman, whose appointment as a Director took effect after the last Annual General Meeting, will retire from office at the 2018 Annual General Meeting and will seek election by shareholders for the first time.

In accordance with the provisions of the UK Corporate Governance Code and as permitted by the Company's Articles of Association, the Board has decided that all other Directors will retire from office at the 2018 Annual General Meeting and each of them will seek re-election by shareholders.

The Chairman confirms that, following a performance evaluation, each Director continues to be effective, demonstrating significant commitment to their roles. The Board believes that the considerable and wide-ranging experience of these Directors will continue to be invaluable to the Company, and recommends their election/re-election.

Biographies of all Directors are set out on pages 56 and 57 of the 2017 Annual Report and Accounts.

Resolutions 11 and 12 – Auditor reappointment and remuneration

At each meeting at which the Annual Report and Accounts are laid, the Company is required to appoint an auditor to serve until the next such meeting. The Audit Committee has recommended to the Board, and the Board now proposes to shareholders, the reappointment of KPMG LLP as the Company's Auditor. The Audit 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. Resolution 12 is a resolution giving the Audit Committee the discretion to determine the Auditor's remuneration.

Resolution 13 – Political donations and expenditure

This resolution renews a similar authority given at last year's Annual General Meeting, which is due to lapse at the 2018 Annual General Meeting. It seeks approval from shareholders to enable the Company, and all companies which are, or which become, subsidiaries of the Company, to make political donations or incur political expenditure which it would otherwise be prohibited from making or incurring by the Companies Act 2006. The Company's policy is not to make donations to political parties nor to incur political expenditure and there is no intention to change that policy. However, the Companies Act 2006 defines political expenditure, political donations and political organisations very widely, such that normal business activities, which might not be thought to be political expenditure or a political donation to a political organisation in the usual sense, may be included. For example, sponsorship of industry forums, funding of seminars and other functions to which politicians are invited, matching employees' donations to certain charities, expenditure on organisations concerned with matters of public policy, law reform and representation of the business community and communicating with the Government and political parties at local, national and European level, may fall under the terms of the Companies Act 2006.

Accordingly, the Company, in common with many other companies, seeks an authority to make political donations as well as to incur political expenditure, to cover these kinds of activities on a precautionary basis, in order to avoid possible inadvertent contravention of the Companies Act 2006. The authority does not purport to authorise any particular donation or expenditure but is expressed in general terms, as required by the Companies Act 2006. Furthermore, as permitted under that Act, the authority has been extended to cover any political donations made or political expenditure incurred by any subsidiaries of the Company. Therefore, as a precautionary measure, you will be asked to give the Company and each of its subsidiaries authority to make political donations to political parties or independent election candidates, to make political donations to political organisations (other than political parties) and to incur political expenditure. This authority is limited to a maximum aggregate amount of £100,000.

If given, this authority will expire at the conclusion of the Company's next Annual General Meeting or at the close of business on 28 June 2019 (whichever is earlier). It is the Directors' intention to renew this authority each year.

Resolution 14 – Authority to allot shares

The Directors currently have an authority to allot shares in the Company and to grant rights to subscribe for or convert any securities into shares in the Company. This authority is due to lapse at the 2018 Annual General Meeting. The Board is seeking to renew that authority over Ordinary shares having an aggregate nominal amount of £23,780,832, representing approximately one third of the issued Ordinary share capital of the Company and also to give the Directors authority to allot Ordinary shares having an aggregate nominal amount of £47,561,664, representing approximately two thirds of the issued Ordinary share capital of the Company by way of a rights issue only. For the avoidance of doubt, the authority sought pursuant to this resolution will give the Directors the ability to allot shares (or grant rights to shares) up to a maximum aggregate nominal amount of £47,561,664. The authority will lapse at the close of business on 28 June 2019 or at the next Annual General Meeting, whichever shall first occur. The authority sought under this resolution is standard for most UK companies and is consistent with The Investment Association's 'Share Capital Management Guidelines'. The Directors have no present intention to issue any shares under the authority being sought. Each reference in this explanatory note to the Company's issued Ordinary share capital is to the issued Ordinary share capital of the Company as at 23 March 2018 (being the latest practicable date prior to the publication of this document). The Company did not hold any shares in treasury as at that date.

Resolutions 15 and 16 – Disapplication of statutory pre-emption rights

These are special resolutions which, if passed by shareholders, will enable the Board to allot Ordinary shares, or to sell any shares out of treasury, for cash, without first offering those shares to existing shareholders in proportion to their existing holdings.

The proposed resolutions essentially replicate the powers which were granted at last year's Annual General Meeting (and which will expire at the 2018 Annual General Meeting). Such powers reflect the Statement of Principles published by the Pre-Emption Group in March 2015, which provide that a company may seek power to issue on a non-pre-emptive basis for cash shares in any one year representing:

(i) no more than 5% of the company's issued ordinary share capital; and

(ii) no more than an additional 5% of the company's issued ordinary share capital provided that such additional power is only used in connection with an acquisition or specified capital investment.

Resolution 15 is proposed as a special resolution. If this resolution is passed by shareholders, it will permit the Board to allot Ordinary shares for cash on a non-pre-emptive basis both in connection with a rights issue or similar pre-emptive issue and, otherwise than in connection with any such issue, up to a maximum nominal amount of £3,567,124. This amount represents approximately 5% of the Company's issued Ordinary share capital as at 23 March 2018 (being the latest practicable date prior to publication of this document). This resolution will permit the Board to allot any such shares for cash in any circumstances (whether or not in connection with an acquisition or specified capital investment).

Resolution 16 is proposed as a separate special resolution. If this resolution is passed by shareholders, it will afford the Board an additional power to allot Ordinary shares for cash on a non-pre-emptive basis up to a further maximum nominal amount of £3,567,124. This amount also represents approximately 5% of the Company's issued Ordinary share capital as at 23 March 2018. The Board will use the power conferred by resolution 16 only in connection with an acquisition or a specified capital investment which is announced contemporaneously with the issue, or which has taken place in the preceding six month period and is disclosed in the announcement of the issue.

The Board confirms its intention to follow the provisions of the 2015 Statement of Principles regarding cumulative usage of authorities within a rolling three year period. Those Principles provide that a company should not issue shares for cash representing more than 7.5% of the company's issued share capital in any rolling three year period, other than to existing shareholders, without prior consultation with shareholders. This limit excludes any ordinary shares issued pursuant to a general disapplication of pre-emption rights in connection with an acquisition or specified capital investment.

Resolution 17 – Purchase of own shares

The proposed resolution seeks authority for the Company to purchase up to a maximum of 28,536,998 of its own Ordinary shares (that is 10% of the Company's issued Ordinary share capital, and therefore within institutional shareholder guidelines, as at 23 March 2018). The Directors are seeking this authority as they consider it prudent for the Company to have the flexibility in its financial management to make market purchases of its own Ordinary shares, despite having no present intention of using the authority sought in this resolution. The reasons why the Directors may, in the future, consider a buy-back of shares to be in the best interests of the Company and its shareholders include where the Directors (i) expect that such a buy-back would result in an increase in earnings per share, (ii) consider that the Company has excess cash, and/or (iii) determine that it is appropriate to increase the Company's gearing.

The resolution specifies the maximum and minimum prices at which Ordinary shares may be bought. Any shares purchased by the Company under this authority would either be cancelled or held as treasury shares, depending on which course of action is considered by the Directors to be in the best interests of shareholders at that time. Treasury shares may subsequently be cancelled, sold for cash or used to satisfy options and awards granted to employees pursuant to the Company's employee share 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. A maximum of 10% of the Company's issued share capital may be held as treasury shares.

As at 23 March 2018, there were options and awards outstanding to subscribe for 6,674,210 Ordinary shares under the Company's shareholder approved employee share schemes. If the outstanding options and awards were fully exercised they would represent approximately 2.3% of the issued Ordinary share capital of the Company. If the buy-back authority was exercised in full, and those shares were cancelled (but the Company's issued Ordinary share capital otherwise remained unaltered), pursuant to this resolution, then the number of options and awards to subscribe for shares outstanding as at 23 March 2018 would represent 2.6% of the reduced issued Ordinary share capital of the Company.

This authority will expire at the conclusion of the next Annual General Meeting of the Company or at the close of business on 28 June 2019, whichever is earlier.

Resolution 18 – Enabling the Company to call a general meeting on 14 days' notice

This resolution renews an authority given at last year's Annual General Meeting and is required as a result of section 307A of the Companies Act 2006. The Company currently has power under its Articles of Association to call general meetings (other than an Annual General Meeting) on at least 14 clear days' notice and would like to preserve this ability. In order to be able to do so, shareholders must first approve the calling of meetings on at least 14 days' notice. This resolution seeks such approval. The approval will be effective until the Company's next Annual General Meeting, when it is intended that a similar resolution will be proposed. The shorter notice period would not be used as a matter of routine for general meetings, but only where the flexibility is merited by the business of the meeting and is thought to be to the advantage of the shareholders as a whole.

NOTES

• 1. A member of the Company entitled to attend, speak and vote at the Annual General Meeting ('the meeting') is also entitled to appoint a proxy or proxies to attend, speak and vote on their behalf provided that if more than one proxy is appointed, each proxy is appointed to exercise rights attaching to different shares. A proxy need not be a member of the Company.
• 1. All resolutions contained in this notice of meeting will be put to vote on a poll. This will result in a more accurate reflection of the views of shareholders by ensuring that every vote is recognised, including the votes of those shareholders who are unable to attend but who have appointed a proxy for the meeting. On a poll, each shareholder has one vote for every share held.
• 1. Members (and any proxies or representatives they appoint) agree, by attending the meeting, that they are expressly requesting and that they are willing to receive any communications (including any communications relating to the Company's securities) made at the meeting.
• 1. A pre-paid proxy form is enclosed with this document. To be valid, the proxy form, together with any power of attorney or other authority (if any) under which it is signed, or a notarially certified copy thereof, should be sent to the Company's registrar, Link Asset Services, PXS 1, 34 Beckenham Road, Beckenham, Kent BR3 4ZF so as to arrive not later than 10.30am on Wednesday 9 May 2018 or, if the meeting is adjourned, no later than 48 hours (excluding any part of a day that is not a working day) before the time of the adjourned meeting.

Alternatively, you may return the proxy form in an envelope to FREEPOST PXS, 34 Beckenham Road, Beckenham BR3 9ZA.

• 1. a) CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the meeting and any adjournment(s) thereof by using the procedures described in the CREST Manual. 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.
• b) 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 & Ireland Limited's 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 Link Asset Services as the issuer's agent (ID RA10) by the latest time for receipt of proxy appointments specified in Note 4 above. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp 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.
• c) CREST members and, where applicable, their CREST sponsors or voting service providers should note that Euroclear UK & Ireland Limited 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. 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 service providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.
• d) 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. Members who have returned proxy forms in accordance with Note 4 or who register the appointment electronically in accordance with Note 5 are not thereby precluded from attending the meeting and voting in person if they so wish.
• 1. A shareholder that is a corporation may authorise one or more persons to act as its representative(s) at the meeting. Each such representative may exercise (on behalf of the corporation) the same powers as the corporation could exercise if it were an individual shareholder, provided that (where there is more than one representative and the vote is otherwise than on a show of hands) they do not do so in relation to the same shares.
• 1. The Company specifies that only those holders of Ordinary shares registered in the register of members of the Company at close of business on Wednesday 9 May 2018 (or, in the event that the meeting is adjourned, in the register of members at close of business on the day that is two days (excluding any part of a day that is not a working day) before the day of the adjourned meeting) shall be entitled to attend and vote at the meeting in respect of the number of Ordinary shares registered in their names at that time. Changes to entries on the register of members after close of business on Wednesday 9 May 2018 (or, in the event that the meeting is adjourned, after close of business on the day that is two days (excluding any part of a day that is not a working day) before the day of the adjourned meeting) shall be disregarded in determining the rights of any person to attend or vote at the meeting.
• 1. This Notice is sent for information only to holders of First Preference shares and Second Preference shares, such holders not being entitled to attend or vote at the meeting.
• 1. As at 23 March 2018 (being the last practicable date prior to the publication of this document) the Company's issued share capital consisted of 285,369,988 Ordinary shares carrying one vote each, 125,327 First Preference shares which do not carry voting rights and 311,954 Second Preference shares which also do not carry voting rights. The total voting rights in the Company as at 23 March 2018 were 285,369,988.

Any person to whom this notice is sent who is a person nominated under section 146 of the Companies Act 2006 to enjoy information rights ('a Nominated Person') may have a right, under an agreement between him and the shareholder by whom he was nominated, to be appointed (or to have someone else appointed) as a proxy for the meeting. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, he may, under any such agreement, have a right to give instructions to the shareholder as to the exercise of voting rights. The statement of the rights of shareholders in relation to the appointment of proxies in Note 1 above does not apply to Nominated Persons. The rights described in that note can only be exercised by shareholders of the Company.
• 1. A shareholder or shareholders having a right to vote at the meeting and holding at least 5% of the total voting rights of the Company (see Note 10), or at least 100 shareholders having a right to vote at the meeting and holding, on average, at least £100 of paid up share capital, may require the Company to publish on its website a statement setting out any matter that such shareholders propose to raise at the meeting relating to the audit of the Company's latest accounts (including the Auditor's report and the conduct of the audit). The Company cannot require the shareholders concerned to pay its expenses in complying with sections 527 and 528 of the Companies Act 2006. The Company must forward any such statement to its Auditor by the time it makes the statement available on the website. The business which may be dealt with at the meeting includes any such statement.

• b) the answer has already been given on a website in the form of an answer to a question; or
• c) it is undesirable in the interests of the Company or the good order of the meeting that the question be answered.
