If the proxy is a legal person, its legal representative or any representative authorised by its board of directors or by other decision-making body shall attend the AGM on its behalf. If the Shareholder is a recognised clearing house (or its agent), the Shareholder may authorise one or more suitable persons to act as its representative at the AGM; however, if more than one person are authorised, the proxy form shall clearly indicate the number and types of shares each person is authorised to represent. The persons after such authorisation may represent the recognised clearing house (or its agent) to exercise the rights, as if they were the individual Shareholders.

A vote made in accordance with the terms of a proxy shall be valid notwithstanding the death or loss of capacity of the appointor or revocation of the proxy or the authority under which the proxy was executed, or the transfer of the shares in respect of which the proxy is given, provided that the Company does not receive any written notice in respect of such matters before the commencement of the AGM.
