While the Government's measures around COVID-19 remain in force, shareholders will not be permitted to attend the meeting in person, and any proxy appointed other than the Chairman will also be prohibited from attending the meeting. Shareholders should therefore appoint the Chairman as their proxy in order to ensure their votes in respect of the resolutions are counted.
• 1. The 'Vote Withheld' option overleaf is provided to enable you to abstain on any particular resolution. However, it should be noted that a 'Vote Withheld' is not a vote in law and will not be counted in the calculation of the proportion of the votes 'For' and 'Against' a resolution.
