If the proxy is being appointed in relation to less than your full voting entitlement, please enter in the box next to the proxy holder's name (see reverse) the number of shares in relation to which they are authorised to act as your proxy. If returned without an indication as to how the proxy shall vote on any particular matter, the proxy will exercise their discretion as to whether, and if so how, they vote (or if this proxy form has been issued in respect of a designated account for a shareholder, the proxy will exercise their discretion as to whether, and if so how, they vote).
