Regardless of whether or not you intend to attend the AGM in person or online, we strongly encourage you to appoint the Chair of the AGM, as opposed to any other person, to act as your proxy to ensure your vote is counted (if, for instance, you orthat other person are not able to attend the AGM in person oronline).

The Chair of the AGM will be appointed as your proxy unless youdelete the words 'Adam Crozier or failing him the correctly appointed Chair of the AGM' and insert the name and address of your proxy in the box below.
