Resolution 3 – Remuneration Report

The Remuneration Report is required to be laid before the shareholders in general meeting and voted on. The Remuneration Report is set out on pages 80 to 86 of the Report and Accounts.

Resolutions 4 to 13 – Directors

The Company's Articles of Association require that once every three years Directors retire by rotation and seek re-election to the Board at an annual general meeting. However, in accordance with the UK Corporate Governance Code, which recommends that all directors of FTSE 350 companies should stand for re-election by shareholders every year, the Board has agreed that all Directors be subject to re-election at this year's Annual General Meeting.

The Chairman has confirmed that following normal performance evaluations, each of the non-executive Directors who are seeking re-election (being Stephen Pettit, Jane Aikman, Norman Blackwell and Steve Marshall) continue to be effective members of the Board and demonstrate commitment to their roles.

The Chairman himself is also seeking re-election and has the support of the Board.

Under the UK Corporate Governance Code the Board is required to set out the reasons for the election of non-executive Directors. Daniela Barone Soares was appointed to the Board in a nonexecutive capacity in November 2011. The Board continually keeps the appropriateness of its composition under review particularly in terms of relevant experience and diversity in its widest sense and believes that Daniela's experience demonstrates this commitment threefold – geographically, in terms of gender and by way of executive experience; and further that she will strengthen the Board with her unique perspective.

The Company's Articles of Association require that all Directors appointed by the Board since the previous annual general meeting should seek election at the next annual general meeting following their appointment. Daniela Barone Soares was appointed to the Board on 10 November 2011 and will be seeking election at this year's Annual General Meeting. The Board recommends that shareholders vote in favour of the election of Daniela Barone Soares and her biographical details are as follows:

Daniela Barone Soares, Non-executive Director

(New York) and Citibank, N.A. (Brazil). Daniela has an MBA from Harvard Business School and a BSc in Economics from Universidade Estadual de Campinas (UNICAMP), Brazil.

Resolution 14 – Reappointment of Auditors

The Company is required to appoint auditors at every general meeting at which accounts are presented and the Directors are proposing the reappointment of Deloitte LLP as the Company's auditors.

Resolution 15 – Auditors' remuneration

The Directors may set the remuneration of the auditors if authorised by the shareholders. This resolution seeks such authorisation.

Resolution 16 – Authority to allot shares

The Directors may only allot shares if authorised to do so by shareholders. The purpose of this resolution is to renew the Directors' authority.

The effect of this resolution will allow the Directors to allot and issue new shares up to a nominal aggregate value of £12,500,000, being just less than one third of the total issued share capital of the Company (excluding treasury shares) as at 13 June 2012 (the latest practicable date prior to the publication of the Notice of Meeting).

In accordance with the Directors' stated intention to seek annual renewal, the authority will expire at the conclusion of the annual general meeting of the Company in 2013. Passing this resolution will give the Directors flexibility to act in the best interests of shareholders, when opportunities arise, by issuing new shares. The Directors have no current plans to make use of this authority except under share plans previously approved in general meeting.

Notes on the Resolutions continued

As at 13 June 2012 (the latest practicable date prior to the publication of the Notice of Meeting), the Company held 1,396,240 treasury shares, which is equal to approximately 0.4% of the issued share capital of the Company (excluding treasury shares) as at that date.

Resolution 17 – Disapplication of pre-emption rights

The Companies Act 2006 requires that, if the Company issues new shares for cash or sells treasury shares, it must first offer them to existing shareholders in proportion to their current holdings.

The effect of this resolution, which will be proposed as a special resolution, is to authorise the Directors to allot new shares pursuant to the authority given in Resolution 16, or sell treasury shares for cash, up to an aggregate nominal amount of £1,890,000 (up to 18,900,000 new ordinary shares) representing approximately 5% of the Company's issued share capital as at 13 June 2012 (being the latest practicable date prior to the publication of the Notice modify statutory pre-emption rights to deal with the legal, regulatory or practical problems that may arise on a rights or other pre-emptive offer or issue. of Meeting) without offering them to shareholders first, and to

The authority will expire at the conclusion of the annual general meeting of the Company in 2013.

The Directors do not intend to issue more than 7.5% of the issued share capital for cash on a non-pre-emptive basis in any rolling three-year period.

Resolution 18 – Authority to purchase own shares

The Directors were authorised at the 2011 annual general meeting to purchase up to 37,600,000 of its own 10p ordinary shares in the market. This authority expires at the end of the 2012 Annual General Meeting. In accordance with the Directors' stated intention to seek annual renewal, this resolution (which will be proposed as a special resolution) will renew this authority until the end of next year's annual general meeting in respect of up to 37,800,000 ordinary shares, which is approximately 10% of the Company's issued share capital (excluding treasury shares) as at 13 June 2012 (the latest practicable date prior to the publication of the Notice of Meeting).

The Directors consider it desirable that the possibility of making such purchases, under appropriate circumstances, is available. The authority, if granted, will only be exercised if market conditions make it advantageous to do so. The Directors will only make purchases under the authority if they believe that to do so would result in an increase in earnings per share for the remaining shareholders and was in the best interests of shareholders generally.

The Directors' present intention is that the shares purchased under the authority will be held in treasury for future cancellation, sale for cash or transfer for the purposes of, or pursuant to, an employee share plan, although in the light of circumstances at the time it may be decided to cancel them immediately on repurchase. The effect of any cancellation would be to reduce the number of shares in issue. For most purposes, while held in treasury, shares are treated as if they have been cancelled (for example, they carry no voting rights and do not rank for dividends).

As at 13 June 2012 (the latest practicable date prior to the publication of the Notice of Meeting) options were outstanding to subscribe for a total number of 2,160,900 ordinary shares, or approximately 0.6% of the Company's issued share capital (excluding treasury shares). If the proposed authority were to be used in full and all of the repurchased shares were cancelled (but the Company's issued share capital otherwise remained unaltered), the total number of options to subscribe for ordinary shares at that date would represent approximately 0.6% of the Company's issued share capital (excluding treasury shares).

Resolution 19 – Notice of general meetings

Changes made to the Companies Act 2006 by the Shareholders' Rights Regulations increase the minimum notice period required for general meetings of the Company to 21 days unless shareholders approve a shorter notice period, which cannot be less than 14 clear days. Annual general meetings continue to held on at least 21 clear days' notice.

Before the Shareholders' Rights Directive came into force on 3 August 2009, the Company was able to call general meetings (other than an annual general meeting) on 14 clear days' notice without obtaining such shareholder approval. In order to preserve this flexibility, Resolution 19 seeks to renew the authority obtained at last year's annual general meeting. It is intended that a shorter notice period will not be used as a matter of routine for general meetings, but only if the flexibility would be helpful given the business of the meeting and where the Board thinks it is in the interest of shareholders as a whole. If the resolution is passed, the authority will be effective until the annual general meeting in 2013, when it is intended that a similar resolution will be proposed.

The Company offers the facility for shareholders to vote and appoint proxies by electronic means. This is accessible to all shareholders and would be available if the Company were to call meetings on 14 clear days' notice.

General Notes

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

• 1. A shareholder entitled to attend and vote at the meeting is entitled to appoint a proxy or proxies to exercise all or any of his/her rights to attend and to speak and vote on his/her behalf at the meeting. A proxy need not be a shareholder of the Company. The return of a completed Proxy Form, other such instrument or any CREST Proxy Instruction (as described in note 11) will not prevent a shareholder from attending the meeting and voting in person if he/she wishes to do so.
• 1. A Proxy Form which may be used to make such appointment and give proxy instructions has been sent to all shareholders (except those who have elected to receive notice via e-mail, who should refer to note 4).
• 1. In order to be valid, an appointment of proxy or proxies must be completed and returned, together with the power of attorney or other authority (if any) under which it is signed, or a duly certified copy of such authority, by one of the following methods:

(a) in hard copy form by post, courier or by hand, to the Company's registrars, Computershare Investor Services PLC;

(b) alternatively, shareholders who have received a Proxy Form may appoint a proxy or proxies electronically via the registrar's website at www.investorcentre.co.uk/eproxy using the Control Number, Shareholder Reference Number (SRN) and PIN; or

(c) in the case of CREST members, by using the CREST electronic proxy appointment service (as set out in note 11);

in each case so that it is received no later than 11.00 am on 20 July 2012, being not less than 48 hours (excluding nonworking days) before the time fixed for the meeting.

• 1. Shareholders who have elected to receive notice via e-mail may appoint a proxy or proxies electronically via the registrar's website, www.investorcentre.co.uk/eproxy using the Control Number, the Shareholder Reference Number (SRN) and PIN. Electronic proxy appointments must be received no later than 11.00 am on 20 July 2012.
• 1. In the case of a joint holding, a proxy need only be signed by one joint holder. If more than one such joint holder tenders a vote, whether in person or by proxy, the vote of the senior shall be accepted to the exclusion of the votes of the other joint holders. Seniority is determined by the order in which the names appear in the Register of Members.
• 1. A shareholder may appoint more than one proxy in relation to the Annual General Meeting provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that shareholder. If in such case a shareholder wishes to appoint more than one proxy, the shareholder should photocopy the Proxy Form and indicate in the box, next to the proxy's name, the number of shares in relation to which the shareholder authorises him/her to act as the shareholder's proxy.
• 1. 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, under an agreement between him/her and the shareholder by whom he/she was nominated, have a right 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/she may, under any such

agreement, have a right to give instructions to the shareholder as to the exercise of voting rights.

The statement of rights of shareholders in relation to the appointment of proxies in paragraphs 1 to 6 does not apply to Nominated Persons. The rights described in these paragraphs can only be exercised by shareholders of the Company.

• 1. 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 at the meeting, will be determined by reference to the Register of Members of the Company at 6.00 pm on the day which is two working days before the day of the 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.
• 1. As at 13 June 2012 (the latest practicable date prior to the publication of this Notice), the Company's issued share capital consisted of 378,555,028 ordinary shares. As at that date the Company held 1,396,240 shares in treasury. Therefore, after excluding treasury shares, the total number of voting rights in the Company as at 13 June 2012 is 377,158,788.
• 1. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so by using the procedures described in the CREST Manual (available via www.euroclear.com/CREST). 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.
• 1. 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 is 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 Company's agent, Computershare Investor Services PLC (ID 3RA50), by the latest time(s) for receipt of proxy appointments set out in note 3. 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 Application Host) from which the Company'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 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, to procure that his 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

General Notes continued

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. A 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 they do not do so in relation to the same shares.
