For the purposes of this Resolution, "rights issue" means an offer to:

as if Section 561(1) of the Companies Act 2006 did not apply to any such allotment;

such authority to expire at the end of the next Annual General Meeting of the Company or at the close of business on 30 September 2017, whichever is the earlier, but so that the Company may, before such expiry, make offers and enter into agreements which would, or might, require equity securities to be allotted and treasury shares to be sold after the authority given by this resolution has expired and the Directors may allot equity securities and sell treasury shares under any such offer or agreement as if the authority had not expired.

BY ORDER OF THE BOARD

Jonathan Bradshaw Company Secretary

27 July 2016

Registered in England and Wales No. 05145017 Registered Office: 133 Houndsditch, London EC3A 7BX

Proxy appointment

1. A member is entitled to appoint another person as his/her proxy to exercise all or any of his/her rights to attend, speak and vote at the Annual General Meeting ("AGM"). A proxy need not be a shareholder of the Company. A shareholder may appoint more than one proxy in relation to the AGM provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that shareholder.
2. 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).
3. A Form of Proxy is enclosed. The appointment of a proxy will not prevent a member from subsequently attending and voting at the meeting in person.
4. To appoint a proxy the Form of Proxy, and any power of attorney or other authority under which it is executed (or a duly certified copy of any such power or authority), must be either (a) sent to the Company's Registrar Capita Asset Services of PXS1, 34 Beckenham Road, Beckenham, Kent, BR3 4ZF, or (b) the proxy appointment must be lodged using the CREST Proxy Voting Service in accordance with Note 12 below in each case so as to be received no later than 10.00 a.m. on 5 September 2016. If you wish, you may register the appointment of a proxy for the AGM electronically, by visiting the Company's Registrar's website www.capitashareportal.com where full details of the procedures are given. The proxy appointment and instructions must be received by Capita Asset Services not less than 48 hours before the time for holding the AGM or adjourned meeting or (in the case of a poll taken otherwise than at or on the same day as the AGM or adjourned meeting) for the taking of the poll at which it is to be used.

Nominated persons

5. The right to appoint a proxy does not apply to persons whose shares are held on their behalf by another person and who have been nominated to receive communications from the Company in accordance with Section 146 of the Companies Act 2006 ("nominated persons"). Nominated persons may have a right under an agreement with the member who holds the shares on their behalf to be appointed (or to have someone else appointed) as a proxy. Alternatively, if nominated persons do not have such a right, or do not wish to exercise it, they may have a right under such an agreement to give instructions to the person holding the shares as to the exercise of voting rights.

Information about shares and voting

6. Holders of ordinary shares are entitled to attend and vote at general meetings of the Company. The total number of issued ordinary shares in the Company on 27 July 2016, which is the latest practicable date before the publication of this document is 287,923,211, carrying one vote each on a poll. Therefore, the total number of votes exercisable as at 27 July 2016 are 287,923,211.

Right to attend and vote

7. Entitlement to attend and vote at the meeting, and the number of votes which may be cast at the meeting, will be determined by reference to the Company's register of members at close of business on 5 September 2016 or, if the meeting is adjourned, 48 hours before the time fixed for the adjourned meeting (as the case may be). In each case, changes to the register of members after such time will be disregarded.

Venue arrangements

8. To facilitate entry to the meeting, members are requested to bring with them the admission card which is attached to the proxy card.
9. Members should note that the doors to the AGM will be open at 9.30 a.m..
10. Mobile phones may not be used in the meeting hall, and cameras and recording equipment are not allowed in the meeting hall.

CREST members

11. 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 of the meeting) by following 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) should refer to their CREST sponsor or voting service provider, who will be able to take the appropriate action on their behalf.
12. 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's specifications and must contain the information required for such instructions, as described in the CREST Manual (available via www.euroclear.com/CREST). 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 RA10 by the latest time(s) 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 a proxy appointed through CREST should be communicated to the proxy by other means.
13. CREST members (and, where applicable, their CREST sponsors or voting service providers) should note that Euroclear 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, to procure that his/her CREST sponsor or voting service provider takes) 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.
14. 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.

Corporate representatives

15. Any corporation which is a member can appoint one or more corporate representatives who may exercise on its behalf all of its powers as a member provided that they do not do so in relation to the same shares.

Notes

Audit concerns

16. Shareholders should note that, under Section 527 of the Companies Act 2006, members meeting the threshold requirements set out in that section have the right to require the company to publish on a website a statement setting out any matter relating to: (i) the audit of the Company's accounts (including the auditor's report and the conduct of the audit) that are to be laid before the AGM for the financial year beginning 1 April 2015; or (ii) any circumstance connected with an auditor of the Company appointed for the financial year beginning 1 April 2015 ceasing to hold office since the previous meeting at which annual accounts and reports were laid. The Company may not require the shareholders requesting any such website publication to pay its expenses in complying with Sections 527 or 528 (requirements as to website availability) of the Companies Act 2006. Where the Company is required to place a statement on a website under Section 527 of the Companies Act 2006, it must forward the statement to the Company's auditor not later than the time when it makes the statement available on the website. The business which may be dealt with at the AGM for the relevant financial year includes any statement that the Company has been required under Section 527 of the

Companies Act 2006 to publish on a website.

Questions

17. Any member or their proxy attending the meeting has the right to ask questions. The Company must cause to be answered any such question relating to the interests of the Company or the good order of the meeting that the question be answered.

business being dealt with at the meeting but no such answer need be given if (a) to do so would interfere unduly with the preparation for the meeting or involve the disclosure of confidential information, (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

Website information

18. A copy of this notice and other information required by Section 311A of the Companies Act 2006 can be found at www.cmcmarkets.com/group/.

Voting by poll

19. Each of the resolutions to be put to the meeting will be voted on by poll and not by show of hands. A poll reflects the number of voting rights exercisable by each member and so the Board considers it a more democratic method of voting. Members and proxies attending the meeting will be asked to complete a poll card to indicate how they wish to cast their votes. These cards will be collected at the end of the meeting. The results of the poll will be published on the Company's website

and notified to the UK Listing Authority once the votes have been counted and verified.

Use of electronic address

20. Members may not use any electronic address provided in either this notice of meeting or any related documents (including the enclosed Form of Proxy) to communicate with the Company for any purposes other than those expressly stated.

Documents available for inspection

21. Copies of the following documents may be inspected during normal business hours on any weekday (Saturdays, Sundays and public holidays excepted) at the 15 minutes before the AGM until it ends:
the Executive Directors' service contracts; and
letters of appointment of the Non-Executive Directors.

registered office of the Company at 133 Houndsditch, London EC3A 7BX up to and including the date of the AGM and at the Company's registered office from

The following pages give an explanation of the proposed resolutions.

Resolutions 1 to 14 are proposed as ordinary resolutions. This means that for each of those resolutions to be passed, more than 50% of the votes cast must be 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 75% of the votes cast must be in favour of the resolution.

Under the Listing Rules, Peter Cruddas and Fiona Cruddas are classed as "controlling shareholders" of the Company. This means that the Independent Non-Executive Directors of the Company must be elected or re-elected by a majority of the votes cast by the independent shareholders of the Company, as well as by a majority of the votes cast by all the shareholders. The independent shareholders of the Company, means all the shareholders of the Company other than Peter Cruddas and Fiona Cruddas. Therefore, the resolutions for the election of the Independent Non-Executive Directors (Resolutions 7 to 9) will be taken on a poll and the votes cast by the independent shareholders and by all the shareholders will be calculated separately. Such resolutions will be passed only if a majority of the votes cast by the independent shareholders are in favour, in addition to a majority of the votes cast by all the shareholders being in favour.

If the ordinary resolution to approve the election of an existing Independent Non-Executive Director is passed, but separate approval by the independent shareholders is not given, the Listing Rules permit an existing Independent Non-Executive Director to remain in office pending a further ordinary resolution of all the shareholders to approve the election of the Director. Such a resolution may only be voted on within the period of between 90 days and 120 days following the date of the original vote.

Resolutions 3-9: Election of Directors

Provision B.7.1 of the UK Corporate Governance Code requires that all the directors of FTSE 350 companies should be subject to annual election by shareholders. As this is the first Annual General Meeting of the Company since listing, all Directors currently in office will therefore seek election at the AGM. Separate resolutions are proposed for each of these elections. A formal Board performance evaluation had not been undertaken since the Company's listing in February 2016. Notwithstanding that an evaluation was not completed, the Chairman confirms that all Directors standing for election at the 2016 AGM continue to be effective and demonstrate commitment to their roles. Biographical details for these Directors are provided on pages 14 to 15.

None of the Independent Non-Executive Directors seeking election at the Annual General Meeting has any existing or previous relationship with the Company, nor with any controlling shareholder of the Company or any associate of a controlling shareholder of the Company within the meaning of LR 13.8.17 R (1).

The Company's Nomination Committee considers the appointment and replacement of Directors subject to the rules set out in the Company's Articles of Association. The Nomination Committee will normally engage an independent search consultant with no connection to the Company to find appropriate candidates for the Board with the requisite skills, and in doing so will take account of relevant guidelines and legislation relating to the appointment of individuals to boards. The Nomination Committee may also consider candidates introduced to the Company from other sources. In considering the Independent Non-Executive Directors' independence, the Board has taken into consideration the guidance provided by the UK Corporate Governance Code. The Board considers James Richards, Manjit Wolstenholme and Malcolm McCaig to be independent in accordance with Provision B.1.1 of the UK Corporate Governance Code.

Resolutions 10 and 11: Re-election of Auditor and Auditor's remuneration

The Company is obliged by law to appoint the Auditor annually. PricewaterhouseCoopers LLP was first appointed as Auditor at the 2010 AGM. This resolution proposes that PricewaterhouseCoopers LLP be reappointed as the Company's Auditor. In Resolution 11, shareholders are being asked to authorise the Group Audit Committee to determine the remuneration of the Company's Auditor.

Resolutions 12 and 13: Directors' remuneration

These resolutions deal with the remuneration of the Directors and seek approval of the Directors' Remuneration Policy and of the remuneration paid to the Directors during the year under review respectively.

The Companies Act 2006 requires the Company to ask shareholders to approve the Directors' Remuneration Policy. This is set out on pages 92 to 100 of the annual report and accounts for the year ended 31 March 2016. Resolution 12 is a binding vote. If approved by shareholders, the Directors' Remuneration Policy will take effect immediately after the end

amended policy.

to allot shares.

The authority in paragraph (i) will allow the Directors to allot new shares and grant rights to subscribe for, or convert other securities into, shares up to a nominal value of £23,993,600, which is equivalent to approximately 33 per cent of the total issued ordinary share capital of the Company, exclusive of treasury shares, as at 27 July 2016.

pre-emption rights

If the Directors wish to allot new shares and other equity securities, or sell treasury shares, for cash (other than in connection with an employee share scheme), company law requires that these shares are offered first to shareholders in proportion to their existing holdings.

The Pre-Emption Group's Statement of Principles, as updated in March 2015, supports the annual disapplication of pre-emption rights in respect of allotments of shares and other equity securities and sales of treasury shares for cash representing no more than 5 per cent of issued ordinary share capital (exclusive

The authority in paragraph (ii) will allow the Directors to allot new shares and grant rights to subscribe for, or convert other securities into, shares only in connection with a rights issue up to a further nominal value of £23,993,600, which is equivalent to approximately 33 per cent of the total issued ordinary share capital of the Company, exclusive of treasury shares, as at 27 July 2016. This is in line with the Investment Association's Share Capital Management Guidelines issued in July 2014. At 27 July 2016, the Company did not hold any shares in The Pre-Emption Group's Statement of Principles also supports the annual disapplication of pre-emption rights in respect of allotments of shares and other equity securities and sales of treasury shares for cash representing no more than an additional 5 per cent of issued ordinary share capital (exclusive of treasury shares), to be used only in connection with an acquisition or specified capital investment. The Pre-Emption Group's Statement of Principles defines "specified capital investment" as meaning one or more specific capital investment related uses for the proceeds of an issue of equity securities, in respect of which sufficient information regarding the effect of the transaction on the Company, the assets the subject of the transaction and (where appropriate) the profits attributable to them is made available to shareholders to enable them to reach an assessment of the potential return.

of treasury shares), without restriction as to the use of proceeds of those allotments.

The Company is also required to annually ask shareholders to approve the remainder of the Directors' Remuneration Report. This is set out on pages 82 to 91 (excluding the Directors' Remuneration Policy on pages 92 to 100) of the annual report and accounts for the year ended 31 March 2016. Resolution 13 is an advisory vote. Resolution 14: Authority to allot shares The purpose of Resolution 14 is to renew the Directors' power Accordingly, the purpose of Resolution 15 is to authorise the Directors to allot new shares and other equity securities pursuant to the allotment authority given by Resolution 14, or sell treasury shares, for cash (i) in connection with a preemptive offer or pre-emptive rights issue or (ii) otherwise up to a nominal value of £3,599,040, equivalent to five per cent of the total issued ordinary share capital of the Company excluding treasury shares, as at 27 July 2016, without the shares first being offered to existing shareholders in proportion to their existing holdings. 10 11

There are no present plans to undertake a rights issue or to allot new shares other than in connection with employee share and incentive plans. The Directors consider it desirable to have the maximum flexibility permitted by corporate governance guidelines to respond to market developments and to enable allotments to take place to finance business opportunities as they arise. If the resolution is passed the authority will expire on the General Meeting in 2017. Resolutions 15 and 16 – Disapplication of Accordingly, and in line with the template resolutions published by the Pre-Emption Group in May 2016, the purpose of Resolution 16 is to authorise the Directors to allot new shares and other equity securities pursuant to the allotment authority given by Resolution 14, or sell treasury shares, for cash up to a further nominal amount of £3,599,040, equivalent to 5 per cent of the total issued ordinary share capital of the Company as at 27 July 2016, exclusive of treasury shares, only in connection with an acquisition or specified capital investment which is announced contemporaneously with the allotment, or which has taken place in the preceding six-month period and is disclosed in the announcement of the issue. If the authority given in Resolution 16 is used, the Company will publish details of the placing in its next annual report.

As at 27 July 2016, the Company did not hold any shares in treasury.

The Board intends to adhere to the provisions in the Preemption Group's Statement of Principles and not to allot shares or other equity securities or sell treasury shares for cash on a non pre-emptive basis pursuant to the authority in Resolution 15 in excess of an amount equal to 7.5 per cent of the total issued ordinary share capital of the Company, excluding treasury shares, within a rolling three-year period, other than:

(i) with prior consultation with shareholders; or

(ii) in connection with an acquisition or specified capital investment which is announced contemporaneously with the allotment or which has taken place in the preceding six-month period and is disclosed in the announcement of the allotment.

The Board considers the authorities in Resolutions 15 and 16 to be appropriate in order to allow the Company flexibility to finance business opportunities or to conduct a pre-emptive offer or rights issue without the need to comply with the strict requirements of the statutory pre-emption provisions.

If Resolutions 15 and 16 are passed the authority will expire on the earlier of 30 September 2017 and at the end of the Annual General Meeting in 2017.

Resolution 17 – Purchase of own shares

The effect of this resolution is to renew the authority granted to the Company to purchase its own ordinary shares, up to a maximum of 28,792,321 ordinary shares, until the Annual General Meeting in 2017 or 30 September 2017 whichever is the earlier. This represents 10% of the ordinary shares in issue as at 27 July 2016 and the Company's exercise of this authority is subject to the stated upper and lower limits on the price payable.

At 27 July 2016, the Company did not hold any shares in treasury.

Although there is no current intention to do so but if any shares are purchased, they will be either cancelled or held as treasury shares, as determined by the Directors at the time of purchase. Shares will only be purchased for the purposes of employee share schemes, or if the Directors consider such purchases to be in the best interests of shareholders generally and that they can be expected to result in an increase in earnings per share. The authority will only be used after careful consideration, taking into account market conditions prevailing at the time, other investment opportunities, appropriate gearing levels and the overall financial position of the Company. Shares held as treasury shares will not automatically be cancelled and will not be taken into account in future calculations of earnings per share (unless they are subsequently resold or transferred out of treasury).

As at 27 July 2016 (being the latest practicable date prior to the publication of this Notice), there were 3,071,712 outstanding share options and awards granted under all share option schemes operated by the Company and NIL outstanding warrants, which, if exercised would represent 1.06% of the issued ordinary share capital of the Company. If this authority were exercised in full, that percentage would increase to 1.17%.

Resolution 18: Notice of general meetings

Under the Companies Act 2006, the notice period required for all general meetings of the Company is 21 days. AGMs will always be held on at least 21 clear days' notice but shareholders can approve a shorter notice period for other general meetings, as long as this is not less than 14 clear days.

In order to maintain flexibility for the Company, Resolution 18 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.
