1. Please insert the number of shares in the Company registered in your name(s) and to which this form of proxy relates. If no such number is inserted, this form of proxy will be deemed to relate to all the shares in the Company registered in your name(s) in the register of the members of the Company.

2. Please insert the full name(s) and address(es) (as shown in the register of the members) in block capitals.

3. Please insert the number of all the shares in the Company registered in your name(s) and delete if inappropriate.

4. If any proxy other than the Chairman is preferred, strike out “the chairman of the meeting, or” and insert the name of the proxy desired in the space provided. Each shareholder is entitled to appoint one or more proxy(ies) to attend and vote at the meeting. A proxy needs not to be a shareholder of the Company. Any alteration made to this form of proxy must be signed by the person who signs it.

5. For resolutions to which the cumulative voting system applies, a shareholder has the same number of votes for each share held as the number of directors standing for election, and may cast all his votes for a single candidate. For example, if the number of director (s) to be elected is 1, the number of votes of a shareholder holding 10,000 shares of the Company is 10,000 (10,000 x 1). A shareholder can, at his own discretion, cast all his votes for one candidate or split his votes among candidates by making a mark in the respective box.

6. This form of proxy must be signed by you or your attorney duly authorised in writing or, in the case of a corporation or institution, either under its common seal or under the hand of an officer or attorney duly authorised in this regard. If the form of proxy is signed by any person other than the holder, the power of attorney or other authority should be notarially certified. To be valid, the notarially certified copy of the power of attorney or other authority, together with the form of proxy, must be delivered to the Company’s registered address, not less than 24 hours before the holding of the EGM.
