Notes

(1) Copies of the directors' service contracts (or, where appropriate, letters of appointment) are available for inspection during normal business hours at the company's registered office on any business day and will be available at the place where the AGM is being held from at least 15 minutes prior to and during the AGM.
(2) To be admitted to the AGM, shareholders are asked to bring their admittance pass or notice of availability card that they have received through the post and be able to confirm their name, address and unique investor code as it appears on the register.
(3) Any shareholder attending the AGM 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 AGM but no such answer need be given if (a) to do so would interfere unduly with the preparation for the AGM or involve the disclosure of confidential information, (b) the answer has already been given on the company's website (www.diageo.com) 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 AGM that the question be answered.
(4) Only holders of Ordinary Shares on the register at 6.00 pm on Monday, 15 October 2012 (or, in the event of any adjournment, the date which is two days before the time of the adjourned meeting) shall be entitled to attend and/or vote at the AGM. Such shareholders can vote in respect of the number of shares registered in their names at that time, but any subsequent changes to the

(5) Any shareholder is entitled to appoint one or more proxies to exercise all or any of his/her rights to attend the AGM and to speak and act on his/her behalf. If a shareholder appoints more than one proxy, each proxy must be appointed to exercise the rights attached to a different share or shares held by that shareholder. A proxy need not be a shareholder of the company. A Form of Proxy which may be used to make such appointment and give proxy instructions can be found on the company's website (www.diageo.com) or can be requested from the Registrar at the address below. To be effective, a duly completed Form of Proxy, together with any power of attorney or other authority under which it is signed or a notarially certified copy of such power or authority, must reach The Registrar, Diageo plc, Edinburgh Park, 5 Lochside Way, Edinburgh EH12 9DT or, in the case of a proxy appointed electronically, the electronic address specified for this purpose on the company's website (please see 'Electronic Voting' on the homepage of www.diageo.com) by 2.30 pm on Monday, 15 October 2012 (or not less than 48 hours before the time fixed for any adjourned AGM). Participants in the company's Employee Share Plans or holders of shares in the Diageo Sharestore should refer to note 10. To appoint a proxy electronically you will need your unique investor code (which can be found on either your share certificate, dividend tax voucher or similar documentation as issued by the Registrar). Please note that any electronic communication that is found to contain a computer virus will not be accepted.

If two or more valid but differing appointments of a proxy are received in respect of the same share for use at the same AGM, the one which is last received (regardless of its date or the date of its signature) shall be treated as replacing and revoking the others as regards that share; if the company is unable to determine which was last received, none of them shall be treated as valid in respect of that share.

(6) Unless voting instructions are indicated on the Form of Proxy, a proxy may vote or withhold his vote as he thinks fit on the resolutions or on any other business (including amendments to resolutions) which may come before the AGM. A vote withheld is not a vote in law and will not be counted in the calculation of the proportion of votes for or against a resolution.
(7) If you are an ordinary shareholder and wish to attend the AGM, the return of the Form of Proxy or the appointment of a proxy via the electronic voting section of the company's website or via CREST will not prevent you from attending and voting in person. In the case of joint holders, any one holder may vote. If more than one holder is present at the AGM, only the vote of the senior will be accepted, seniority being determined by the order in which names appear on the register.
(8) A shareholder must inform the company in writing of any termination of the authority of a proxy.
(9) CREST members who wish to appoint and/or give instructions to a proxy or proxies through the CREST electronic proxy appointment service may do so in accordance with the procedures described in the CREST manual

(available via www.euroclear.com/CREST). In order for a proxy appointment made through CREST to be valid, the appropriate CREST message (a 'CREST Proxy Instruction') must be properly authenticated in accordance with Euroclear UK and Ireland Limited specifications and must contain the information required for such instructions, as described in the CREST Manual. The message must be transmitted so as to be received by the issuer's agent (ID R015) by the latest time(s) for receipt of proxy appointments as set out in note 5 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 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. 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.

CREST personal members or other CREST sponsored members, and those CREST members who have appointed a 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.

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 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, to procure that his/her 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 system provider are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.

(10) Participants in the company's Employee Share Plans and holders of shares in the Diageo Sharestore should complete the Letter of Direction section of the Form of Proxy. Those who are ordinary shareholders and/or participants in such plans and/or holders of shares in the Diageo Sharestore should complete both the Form of Proxy and the Letter of Direction section. The Letter of Direction must reach the Registrar (at the address specified in note 5), or in the case of a Letter of Direction completed electronically, the electronic address specified for this purpose on the company's website (please see 'Electronic Voting' on the homepage of www.diageo.com), by 2.30 pm on Thursday, 11 October 2012. The votes of employees or former employees of the company will be taken to include their Employee Share Plans and Sharestore shares together with holdings in their own name unless they notify the Registrar to the contrary at least 48 hours before the AGM. Holders of shares in the Diageo Sharestore should contact the Registrar and request a letter of admittance should they wish to attend the company's AGM.

(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, if it is appointing more than one corporate representative, it does not do so in relation to the same shares.
(12) On arrival at the AGM venue, all those entitled to vote will be required to register and collect a poll card. In order to facilitate these arrangements, please arrive at the AGM venue in good time. You will be given instructions on how to complete your poll card at the AGM.
(13) As soon as practicable following the AGM, the results of the voting at the AGM and the number of votes cast for and against and the number of votes withheld in respect of each resolution will be announced via a Regulatory Information Service and placed on the company's website (www.diageo.com).
(14) A copy of this AGM notice has been provided for information only to persons who have been nominated by a shareholder to enjoy information rights under section 146 of the Act ('Nominated Persons'). The statement of the rights of shareholders in relation to the appointment of proxies does not apply to Nominated Persons. However, a Nominated Person may, under an agreement between him and the shareholder by whom he was nominated, have a right to be appointed (or to have someone else appointed) as a proxy for the AGM or to have someone else so appointed. If a Nominated Person does not have such a right or does not wish to exercise it, he may have a right under such an agreement to give instructions to the shareholder as to the exercise of voting rights.
(15) Under section 527 of the Act shareholders that meet 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; or
ii. any circumstance connected with an auditor of the company ceasing to hold office since the previous AGM at which annual accounts and reports were laid in accordance with section 437 of the Act.

The company may not require the shareholders 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 AGM includes any statement that the company has been required under section 527 of the Act to publish on a website.

(16) A copy of this AGM notice, and other information required by section 311(A) of the Act can be found at the company's website (www.diageo.com).
(17) Any electronic address provided either in this AGM notice or any related documents (including the Chairman's letter and Form of Proxy) may not be used to communicate with the company for any purposes other than those expressly stated.

(18) The company's issued share capital at 13 August 2012, the latest practicable date prior to publication of this AGM notice (the 'Latest Practicable Date'), was 2,506,110,063 Ordinary Shares carrying one vote each, excluding any Ordinary Shares held as treasury shares. As at the Latest Practicable Date, the company held 248,005,922 Ordinary Shares as treasury shares, representing 10% of the company's issued share capital (excluding treasury shares) as at that date. As at the Latest Practicable Date, the total number of voting rights in the company was therefore 2,506,110,063.

To the ordinary shareholders, employees and former employees who are holders of Ordinary Shares in the Diageo Sharestore, participants in the Profit Sharing Plans, The Diageo plc 2009 International Share Match Plan and the 2001 Share Incentive Plan of Diageo ('Employee Share Plans') and, for information only, to participants in other Diageo share plans.

Dear Shareholder

Annual General Meeting

The AGM of Diageo plc will be held at Church House Conference Centre, Dean's Yard, Westminster, London SW1P 3NZ on Wednesday, 17 October 2012 at 2.30 pm.

My explanation of each of the resolutions to be proposed is set out below. All resolutions will be proposed as ordinary resolutions, save for resolutions 18, 19 and 21 which will be proposed as special resolutions. Voting at the AGM will be by way of poll rather than on a show of hands, using a poll card. This is a more transparent method of voting as shareholder votes are to be counted according to the number of shares held. This will ensure an exact and definitive result.

Resolution 1 (report and accounts 2012)

These Diageo annual reports and accounts are for the year ended 30 June 2012.

Resolution 2 (directors' remuneration report 2012)

Sections 439 and 440 of the Act require that quoted companies put the directors' remuneration report to a vote of the shareholders. The vote is advisory only, however, and the directors' entitlement to remuneration is not conditional on the resolution being passed.

Resolution 3 (declaration of final dividend)

The company paid an interim dividend of 16.60 pence per Ordinary Share in April 2012. The board recommends a final dividend of 26.90 pence per Ordinary Share, bringing the total dividend for the year to 43.50 pence per Ordinary Share. Subject to approval by shareholders, the final dividend will be paid on 22 October 2012 to shareholders on the register on 7 September 2012. A Dividend Reinvestment Plan ('DRIP') is available in respect of this dividend and the plan notice date is 1 October 2012. A DRIP booklet and mandate form are available from the Registrar at the address given in note 5 on page 5 of this AGM notice or from the company's website (www.diageo.com).

Resolutions 4 to 14 (directors seeking election and re-election)

The company's articles of association provide that any director who has been appointed by the Board since the last AGM is required to retire and may then be considered for election assuming they wish to stand for election. The directors appointed since the last AGM are Ho KwonPing and IM Menezes, and both are seeking election.

In accordance with the UK Corporate Governance Code, all of the other directors of the company will stand for re-election.

In relation to the re-election of non-executive directors, PB Bruzelius, LM Danon, Lord Davies, BD Holden, PG Scott and HT Stitzer, I can confirm that a formal performance evaluation has been completed and the Board has determined that each of them is independent, is experienced and all are influential individuals from a range of industries, backgrounds and countries.

Their diverse mix of skills and business experience is a major contribution to the proper functioning of the board and its committees, ensuring that matters are fully debated and that no individual or group dominates the board's decision-making processes. The board considers that Ho KwonPing's knowledge, experience and skills will further enhance the effectiveness of the board. The board also considers that IM Menezes's experience will make a significant contribution to the executive leadership of the company.

Biographical details of the company's directors seeking election and re-election are set out in the Appendix to this letter.

Resolution 15 (re-appointment of auditor)

At each general meeting at which accounts are laid before the members, the company is required to appoint an auditor to serve until the next such meeting. KPMG Audit Plc has agreed to continue as the company's auditor in respect of the financial year ending 30 June 2013.

Resolution 16 (remuneration of auditor)

Resolution 16 authorises the board to determine the remuneration of the company's auditor.

Resolution 17 (authority to allot shares)

At the AGM held on 19 October 2011, shareholders gave authority to the board, which will expire on 17 October 2012, to allot a maximum of £241,511,000 in nominal value of Ordinary Shares and any securities convertible into Ordinary Shares. Resolution 17 replaces the authority granted in 2011 and would allow the board to allot, or to grant rights to subscribe for or convert any securities into Ordinary Shares up to an aggregate nominal amount equal to £241,715,000 (representing 835,370,000 Ordinary Shares). This amount represents approximately

one-third of the company's issued share capital (excluding treasury shares) as at the Latest Practicable Date.

The authority sought under this resolution will expire at the earlier of 31 December 2013 and the conclusion of next year's AGM. The board will continue to seek to renew this authority at each AGM, in accordance with current best practice.

The board has no present firm intention to exercise the authority sought under resolution 17, except to satisfy options under the company's share option plans.

As at the Latest Practicable Date, 248,005,922 Ordinary Shares are held by the company in treasury (representing 10% of the total issued share capital (excluding treasury shares) of the company).

Resolution 18 (disapplication of pre-emption rights)

Resolution 18 would give the board the authority to allot Ordinary Shares (or sell any Ordinary Shares which the company elects to hold in treasury) for cash without first having to offer them to existing shareholders in proportion to their existing shareholdings.

This authority would be limited to allotments of new Ordinary Shares or sales of treasury shares, for cash, in connection with pre-emptive offers or to allotments of equity securities to employees of joint ventures in which the group participates, or as the board otherwise considers necessary, up to an aggregate nominal amount of £39,845,000 (representing 137,705,000 Ordinary Shares), equivalent to 5% of the issued Ordinary Share capital (including treasury shares) of the company as at the Latest Practicable Date. In respect of this

aggregate nominal amount, the board confirms its intention to follow the provisions of the Pre-Emption Group's Statement of Principles regarding cumulative usage of authorities of no more than 7.5% of the issued Ordinary Share capital (excluding treasury shares issued for cash) within a rolling 3 year period without prior consultation with shareholders. The board will continue to seek to renew this authority at each AGM, in accordance with current best practice.

This authority will expire at the earlier of 31 December 2013 and the conclusion of next year's AGM.

Resolution 19 (authority to purchase own ordinary shares)

At the AGM held on 19 October 2011, the shareholders granted authority for the company to buy up to a maximum of 250,399,000 of its own Ordinary Shares in the market.

Resolution 19 renews and replaces that authority and would allow the company to buyback up to 250,611,000 Ordinary Shares (i.e. £72,514,000 in nominal value) in the market (10% of the issued Ordinary Share capital, exclusive of treasury shares, at the Latest Practicable Date). The company had options to subscribe for Ordinary Shares outstanding at the Latest Practicable Date relating to 490,649 Ordinary Shares. This figure represents 0.02% of the issued Ordinary Share capital (exclusive of treasury shares), at the Latest Practicable Date and would, assuming no further Ordinary Shares are issued, represent 0.02% of the issued Ordinary Share capital if full authority to purchase shares (both the existing authority and that sought at this year's AGM) was used.

The resolution sets out the lowest and highest prices that the company can pay for the Ordinary Shares (for each Ordinary Share, the lowest being the nominal value of an Ordinary Share and the highest being the higher of (i) 105% of the average middle market quotation for an Ordinary Share as derived from the London Stock Exchange Daily Official List for the five business days preceding the day of purchase and (ii) the higher of the price of the last independent trade and the highest current independent bid on the London Stock Exchange at the time the purchase is carried out). The authority will expire at the conclusion of next year's AGM or on 31 December 2013, if earlier. Any buyback would be by market purchases through the London Stock Exchange.

Any Ordinary Shares so purchased would be either held as treasury shares or cancelled. In the period from 20 October 2011 to the Latest Practicable Date, 2,786,000 Ordinary Shares have been purchased and held as treasury shares under the existing authority.

The board would only authorise such purchases after careful consideration, taking account of other investment opportunities, appropriate gearing levels, the overall financial position of the group and whether the effect would be an increase on earnings per share and in the best interests of shareholders generally.

Resolution 20 (political donations and political expenditure in the European Union ('EU'))

Under section 366 of the Act, the company is required to seek shareholders' authority for any political donations and/or political expenditure made by the company in the EU. On 19 October 2011 the board was granted authority to make such political donations and/or incur such political expenditure, capped at £200,000.

Within the EU, it has been the company's longstanding practice not to make payments to political parties and the intention is that this will remain the case. However, the legislation is very broadly drafted and may catch activities such as funding seminars and other functions to which politicians are invited, supporting certain bodies involved in policy review, and law reform and matching employees' donations to certain charities. The group made no donations to EU political organisations and incurred no EU political expenditure during the year. The group made contributions to non-EU political parties totalling £0.4 million during the year (2011 – £0.6 million). These were all made, consistent with applicable laws, to federal and state candidates and committees in North America, where it is common practice to make political contributions. No particular political persuasion was supported and contributions were made with the aim of promoting a better understanding of the group and its views on commercial matters, as well as a generally improved business environment.

The board has decided to continue to seek shareholders' authority for political donations and political expenditure in the EU in case any of the company's normal activities are caught by the legislation. The authority sought would be capped at £200,000 for the next year. The authority will expire at the conclusion of next year's AGM or on 31 December 2013, if earlier. The board will continue to seek to renew this authority at each AGM, in accordance with current best practice.

Resolution 21 (reduced notice of a general meeting other than an annual general meeting)

Changes made to the Act by the Companies (Shareholders' Rights) Regulations 2009 require the company to call general meetings (other than AGMs) on at least 21 clear days' notice unless the company:

has obtained shareholder approval for the holding of such general meetings on 14 clear days' notice by passing a special resolution at its most recent AGM (or at a general meeting held since the AGM); and
offers the facility to vote by electronic means for all shareholders who are entitled to vote.

Following shareholder approval at the 2011 AGM, which currently allows the company to call general meetings (other than AGMs) on 14 clear day's notice, shareholders are being asked to approve Resolution 21, to preserve this ability.

The approval will be effective until the company's next AGM. The company does not intend to use this authority routinely, but only in limited circumstances for time-sensitive matters where a shorter notice period would be advantageous to shareholders as whole.

Issued share capital

The company's issued share capital at the Latest Practicable Date was 2,506,110,063 Ordinary Shares carrying one vote each, excluding any Ordinary Shares held as treasury shares. As at the Latest Practicable Date, the company held 248,005,922 Ordinary Shares as treasury shares,

representing 10% of the company's issued share capital (excluding treasury shares) as at that date. As at the Latest Practicable Date, the total number of voting rights in the company was therefore 2,506,110,063.

Warning to shareholders – share fraud

Please beware share fraud or 'boiler room' scams, where shareholders are called 'out of the blue' by fraudsters (sometimes claiming to represent Diageo) attempting to obtain money or property dishonestly. Further information is available in the investor section of the company's website (www. diageo.com) but in short, if in doubt, take proper professional advice before making any investment decision.

Recommendation

The board considers that the resolutions contained in this AGM notice and to be proposed at the AGM are in the best interests of the company and shareholders as a whole and recommend that you vote in favour of them. Directors who hold shares in the company intend to vote in favour of these resolutions in respect of their own beneficial holdings.

Yours sincerely
