THIS DOCUMENT IS IMPORTANT AND REQUIRES YOUR IMMEDIATE ATTENTION. IF YOU ARE IN ANY DOUBT AS TO THE ACTION TO BE TAKEN YOU SHOULD CONSULT YOUR STOCKBROKER OR OTHER FINANCIAL ADVISER AUTHORISED UNDER THE FINANCIAL SERVICES AND MARKETS ACT 2000.

Letter from the Chairman

Dear Shareholder,

The Annual General Meeting of Diploma PLC (the "Company") will be held in the Brewers' Hall, Aldermanbury Square, London EC2V 7HR on Wednesday, 21 January 2015 at 12.00 midday. As you can see from the Notice of the Annual General Meeting which follows this letter, there are 17 items of Business to be discussed.

Recommendation and Action to be Taken

The Board is unanimous in its view that the adoption of the Resolutions set out in the Notice of Annual General Meeting are in the best interests of the Company and its shareholders as a whole. Accordingly, the Board recommends that you vote in favour of the resolutions. Each Director intends to vote in favour of the resolutions in respect of his own beneficial holding, which in aggregate amount to 1,873,297 shares at the date of this letter.

Ordinary shareholders are requested, whether or not they propose to attend the Annual General Meeting, to complete and return the enclosed form of proxy to Computershare Investor Services PLC, (The Pavilions, Bridgwater Road, Bristol, BS99 6ZY) so as to arrive as soon as possible, but in any event by no later than 48 hours before the time of the meeting. The lodging of forms of proxy will not prevent ordinary shareholders from attending and voting in person if they so wish.

In line with best practice, all resolutions for consideration at the Meeting will be decided on a poll, rather than on a show of hands. We believe that a poll is the best way of representing the views of as many shareholders as possible in the voting process, including all votes of shareholders who are unable to attend the Meeting, but who appoint a proxy for the meeting. This means that a shareholder has one vote for every share held.

The results of the poll will be announced through Regulatory News Service ("RNS") and will be made available on the Company's website as soon as practicable, following the closing of this year's Annual General Meeting.

This will be my last meeting as Chairman as I will be retiring at the conclusion of the Annual General Meeting. I should like to thank all my colleagues on the Board, past and present, who have always been both supportive and challenging, as needed. Their wise counsel and experience has made a substantial contribution to the success of the Group. Finally, I am delighted that in John Nicholas, the Company has a highly successful businessman with broad and relevant experience, who I am confident will chair the Group well on the next stage of its journey and to further success.

I look forward to seeing you at the Annual General Meeting and thank you for your continued support.

Yours faithfully

JL Rennocks Chairman

5 December 2014

As a consequence, Ordinary Resolutions 3 to 8 deal with the re-election of each Director of the Board.

Explanatory Notes to the Notice continued

Resolutions 9 and 10

Ordinary Resolutions 9 and 10 deal with the reappointment of Deloitte LLP as Auditor and the authorisation of the Directors to set the Auditor's remuneration.

Resolutions 11 and 12 – Directors' Remuneration

Ordinary Resolutions 11 and 12 deal with Directors' remuneration and seek approval of the Directors' Remuneration Policy and of the Annual Report on Directors' Remuneration during the year under review, respectively.

Resolution 11 is to approve the Directors' Remuneration Policy. During the year the Remuneration Committee undertook a detailed review of its Remuneration Policy for Executive Directors to ensure that it remains appropriate as the Company develops. This review has concluded and as a result, the Committee proposes to make a number of changes to the existing Directors' Remuneration Policy which was approved by the shareholders at last year's Annual General Meeting.

Further details of the proposed changes to the Directors' Remuneration Policy are described in the Remuneration Committee Chairman's letter to shareholders on page 52 and on page 55 of the Annual Report & Accounts 2014. The new Directors' Remuneration Policy is set out on pages 54 to 59 of the Annual Report & Accounts for the year ended 30 September 2014.

If approved by shareholders, the Directors' Remuneration Policy will take effect immediately after the end of the Annual General Meeting and will apply for the next three years to 21 January 2018 or until replaced by a new or amended policy.

Resolution 12 continues the practice of an annual advisory vote to approve the Annual Report on Directors' Remuneration for the year ended 30 September 2014, which is set out as the Annual Report on Remuneration on pages 52 and 53 and 60 to 67 of the Annual Report & Accounts 2014.

Resolution 13 – Amendment of Individual Limits under 2011 Performance Share Plan (the "PSP")

Resolution 13 is subject to and conditional on the passing of Resolution 11 as the proposed revised Directors' Remuneration Policy impacts the operation of the Company's Long Term Incentive Plans ("LTIPs"). Under the proposed changes, the Company will lower the overall quantum of future awards that can be made under the LTIPs from 200% to 175% of basic salary (250% in exceptional circumstances). This will be achieved by a discontinuation of the 2011 Share Matching Plan under which 100% of basic salary was awarded annually and by increases in the award levels under the 2011 Performance Share Plan, under which 175% of basic salary can in future be awarded annually in normal circumstances (250% of basic salary in exceptional circumstances).

Resolution 14 – Authority to Allot Shares

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 in respect of the allotment of shares will expire on 21 January 2015. 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 £1,887,326. This amount represents approximately one third of the total issued ordinary share capital of the Company as at 4 December 2014, the latest practicable date before the publication of the Notice.

In accordance with the institutional guidelines issued by the Investment Management Association ("IMA"), 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 £3,774,652. This amount represents approximately two thirds (66.67%) of the Company's existing issued share capital calculated as at 4 December 2014, the latest practicable date before the publication of the Notice. The Directors have no present intention of exercising these authorities.

If given, these authorities will expire at the Annual General Meeting in 2016 or 21 April 2016, whichever is the earlier.

Resolution 15 – Disapplication of Pre-Emption Rights

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 in respect of the disapplication of Pre-Emption Rights will expire on 21 January 2015. Accordingly, Resolution 15 will be proposed as a Special Resolution to grant such a power. Apart from offers or invitations, the authority will be limited to the allotment of equity securities and sales of treasury shares for cash up to an aggregate nominal amount of £283,099 (being 5% of the issued ordinary share capital at 4 December 2014). If given, this authority will expire on the earlier of 21 April 2016 and the conclusion of the Annual General Meeting in 2016. Your Directors will have due regard to institutional guidelines 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. Your Directors do not have any present intention of exercising this authority, but consider it desirable to have the flexibility to use it, if appropriate.

Resolution 16 – Authority to make Market Purchases of Ordinary 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. 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. In the event that shares are purchased, they would either be cancelled (and the number of shares in issue would be reduced accordingly) or, subject to the Companies Act 2006 (the "Act"), be retained as treasury shares. The Act enables companies to hold shares repurchased as treasury shares with a view to possible resale at a future date rather than having to cancel them. The Company will consider holding repurchased shares pursuant to the authority conferred by this resolution as treasury shares. This would give the Company the ability to reissue treasury shares quickly and cost effectively and would provide the Company with additional flexibility in the management of its capital base. The Directors will only exercise this authority if they are satisfied that a purchase would result in an increase in expected earnings per share and would be in the interests of shareholders generally. This resolution is to be renewed for the period ending on the earlier of 21 April 2016 and the conclusion of the Annual General Meeting in 2016.

At the date of this letter the Company does not hold any treasury shares.

Resolution 17 – Notice Period for General Meetings

This Resolution is required under the changes made to the Act to implement the Shareholder Rights Directive. The Act increases the notice period for general meetings of companies such as ours to 21 days, unless certain conditions are met in which case it will be 14 clear days notice. To ensure that our general meetings (other than annual general meetings) may be held on not less than 14 clear days notice, one of the conditions needing to be met is that a shareholder resolution reducing the period of notice to not less than 14 clear days has been passed at the immediately preceding Annual General Meeting. 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. The approval will be effective until the Company's next Annual General Meeting.

Information for Shareholders

1 Entitlement to Attend and Vote

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 close of business on the day which is two days before the day of the meeting or, if the meeting is adjourned, to the Register of Members of the Company at close of business on the day which is two days before the day of any adjourned meeting. Changes to entries on the Register of Members after that time shall be disregarded in determining the rights of any person to attend and vote at the meeting.

2. Poll Voting

In line with best practice, voting at the Annual General Meeting will be on a poll rather than on a show of hands. Each shareholder present at the meeting will be entitled to one vote for every share registered in his or her name and each corporate representative or proxy will be entitled to one vote for each share which he or she represents. Shareholders who vote in advance of the meeting and appoint the Chairman as their proxy, but who attend the meeting in person, need not complete a poll card unless they wish to change their vote. The results of the voting will be announced through RNS and will be published on the Company's website www.diplomaplc.com after the Meeting on Wednesday, 21 January 2015 or as soon as reasonably practicable thereafter.

3. Appointment of Proxies

A member is entitled to appoint another person as his proxy to exercise all or any of his rights to attend, to speak and to vote at the meeting. A member may appoint more than one proxy in relation to the meeting, provided that each proxy is appointed to exercise the rights attached to a different share or shares held by him. A proxy need not be a member of the Company. To be valid any form of proxy must be received by post or by hand (during normal business hours only) by the Company's Registrars, Computershare Services PLC, The Pavilions, Bridgwater Road, Bristol, BS99 6ZY, or at the electronic address provided in the form of proxy/ website, in each case no later than 48 hours before the time of the meeting. If you are a CREST member, see note 4 below.

4. CREST Electronic appointment of Proxies

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 3RA50) by 12 noon on Monday, 19 January 2015. 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. 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 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.

1. The appointment of a proxy does not prevent a member who so wishes from attending the meeting and voting in person.

6. Corporate Representatives

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.

7. Nominated Persons

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/her and the member by whom he/she was nominated, to be appointed (or to have someone else appointed) as a proxy for the meeting. If a Nominated Person has no such 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 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. Shareholders' Right to ask questions

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

12. Audit Concerns

Under Section 527 of the Companies Act 2006 (the "Act"), 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 Annual General Meeting; or (ii) any circumstance connected with an auditor of the Company appointed for the financial year beginning on 1 October 2013 ceasing to hold office since the previous meeting at which annual accounts and reports were laid in accordance with Section 437 of the Act, (in each case) that the members propose to raise at the Annual General Meeting. The Company may not require the members requesting any such website publication to pay its expenses in complying with Sections 527 or 528 of the Act. Where the Company is required to place a statement on a website under Section 527 of the Act, 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 meeting includes any statement that the Company has been required under Section 527 of the Act to publish on a website.

13. Shareholder Resolution

Under Section 338 and Section 338A of the Companies Act 2006, members meeting the threshold requirements in those sections have the right to require the Company (i) to give, to members of the Company entitled to receive notice of the Annual General Meeting, notice of a resolution which may properly be moved and is intended to be moved at the meeting and/or (ii) to include in the business to be dealt with at the meeting any matter (other than a proposed resolution) which may be properly included in the business. A resolution may properly be moved or a matter may properly be included in the business unless (a) (in the case of a resolution only) it would, if passed, be ineffective (whether by reason of inconsistency with any enactment or the Company's constitution or otherwise), (b) it is defamatory of any person, or (c) it is frivolous or vexatious. Such a request may be in hard copy form or in electronic form, must identify the resolution of which notice is to be given or the matter to be included in the business, must be authorised by the person or persons making it, must be received by the Company not later than six clear weeks before the meeting, and (in the case of a matter to be included in the business only) must be accompanied by a statement setting out the grounds for the request.
