• • We have determined to hold our AGM electronically to ensure that shareholders who wish to attend the AGM are able to do so. The Company's Articles of Association permit us to hold an electronic AGM and we have decided to make use of this provision. For full details of how this will work and to register for the AGM, please see page 6 of the Notice of Meeting.

• • The 'Vote Withheld' option is given to enable you to abstain on any particular resolution. The '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.
