Explanatory notes for completing the Proxy Form

• 1. If you wish to appoint a person other than the Chairman, delete the words 'the Chairman of the meeting' and insert the name of the person you wish to appoint as your proxy in the space provided. A proxy need not be a member of the company.
• 1. You may appoint more than one proxy in relation to your shareholding provided that each proxy is appointed to exercise the rights attached to a different share or shares. You must complete separate proxy forms for each proxy appointed. The proxy form is available on the company's website (www.diageo.com) or you may photocopy this form. Photocopies may only be used in respect of the same registered shareholder name (and designated account as applicable) as it appears on the original form. Alternatively, proxy forms are available from the Registrar, Link Group, Central Square, 29 Wellington Street, Leeds, LS1 4DL. Please indicate in the box beneath the proxy's name, the number of shares in respect of which the relevant proxy is authorised to act on your behalf. If the box beneath the proxy's name is left blank, your proxy will be deemed to be authorised in respect of all shares (or, if this proxy form has been issued in respect of a designated account for a shareholder, the full voting entitlement for that designated account). Please tick the box provided to indicate if you are appointing multiple proxies. All forms must be signed and should be returned together in one envelope to the address on the back of this proxy form (reply paid in the UK).
