4. If no person is appointed as proxy, the Chairman of the EGM will be deemed to have been appointed by you as your proxy.

5. For Resolutions nos. 1 to 4: If you wish to vote for any of the resolutions, please insert a “✓” in the box marked “FOR” or if you wish to vote against any of the resolutions, please insert a “✓” in the box marked “AGAINST”; or if you wish to abstain from voting for or against the resolution, please insert a “✓” in the box marked “ABSTAIN”. If no indication is given, then your proxy/proxies may vote in such manner as he/she/they think(s) fit. Your proxy will also be entitled to vote at his discretion on any resolution properly put to the Meeting other than those referred to in the notice convening the EGM. The shares abstained will be counted in the calculation of required majority.

6. For Resolutions no. 5.00 and no. 6.00: “Accumulative voting” will be used in carrying out the voting and the counting of voting results in respect of Resolutions no. 5.00 and no. 6.00.

In “accumulative voting” for every share held by a shareholder who participates in the voting, the shareholder will have the same number of voting rights which equals the number of directors/supervisors to be elected. Such shareholder may cast all his/her votes on one single candidate or different candidates separately.

No ballot will be cast under “For”, “Against” or “Abstain” in accumulative voting. Where the votes cast for a certain candidate of director or supervisor of the Company are more than half of the total number of shares held by all shareholders attending the EGM (before accumulation), such candidate shall be elected as a director or supervisor of the Company.

Please fill in the blanks entitled “Accumulative Voting” under Resolutions no. 5.00 and no. 6.00 in accordance with the following instructions:

(1) For every share held by you, you will have the same number of voting rights which equals the number of directors or supervisors of the Company to be elected in each resolution. For example, if you are holding 1 million shares of the Company, (a) the aggregate number of votes which you will have in respect of Resolution no.5.00 will be 1 million (i.e. 1 million shares x 1 = 1 million voting shares); (b) the total number of votes which you will have in respect of Resolution no. 6.00. will be 1 million (i.e. 1 million shares x 1 = 1 million voting shares).

(2) You may cast all your votes on one candidate or cast any portion of your votes on different candidates in any combination. Please fill in the number of votes you wish to cast for certain candidate(s) in the “Accumulative Voting” column.

(3) If you mark “✓” and also fill in the number of votes cast in the “Accumulative Voting” column under certain candidate(s), such number of votes filled in shall prevail for the counting of votes; if you mark “✓” without filling in number of votes cast in the “Accumulative Voting” column under certain candidate(s), it shall be deemed that you have cast all your votes to a certain candidate or allocated all your votes to certain candidates equally.

(4) Where the total number of votes cast by a shareholder for one or several of the candidate(s) of directors is in excess of the number of votes carried by the total number of shares held by him, the votes cast by the shareholder shall be invalid, and the shareholder shall be deemed to have waived his voting rights. Where the total number of votes cast for one or several candidate(s) of directors by a shareholder is less than the number of votes carried by the total number of shares held by such shareholder, the votes cast by the shareholder shall be valid, and the voting rights attached to the shortfall between the votes actually cast and the votes which the shareholder is entitled to cast shall be deemed to have been waived by the shareholder.

7. This form of proxy must be signed by you or your attorney duly authorised in writing or, in the case of a company or an organization, either under the common seal or under the hand of any director or attorney duly authorised in writing. In any event, the execution shall be made in accordance with the articles of association of such company or organization.
