4. Attention: According to the Articles of Association, cumulative voting system will be adopted in respect of the above resolutions no. 4 and 5, and other resolutions will be voted by one-share-one-vote system.

In this election of Directors, independent non-executive Directors and other Board members are elected separately. The number of executive Directors and independent non-executive Directors to be elected in the EGM will be five and four, respectively. To ensure that your voting rights is fully exercised, the following notes basing on resolution no. 4 as an example briefly explain matters that you should be aware of when completing the number of votes under the "cumulative voting system" (matters to be aware of in respect of resolution no. 5 is the same as for resolution no. 4). Please refer to the following explanation and fill in your votes for resolutions no. 4 and 5:

(i) In respect of resolution no. 4, each share you hold has voting rights equal to the total number of executive Directors to be elected. For example, if you hold 1 million shares, and the total number of executive Directors to be elected is five, the total number of shares for which you have the voting rights under resolution no. 4 will be 5 million shares (i.e. 1 million shares x 5 = 5 million shares).

(ii) Please state the number of votes in the column "for" and/or "against" and/or "abstain" you give to each of the candidates for election as executive Director. Please note that you may give equal number of votes to each candidate, or give all your votes as represented by the shares you hold to one particular candidate as executive Director, or a certain number of votes as represented by the shares you hold to certain candidates (one to five, similar hereinafter) as executive Director. For example, if you own 1 million shares of the Company, and five executive Directors should be elected in this election, the total number of shares for which you have the voting rights under resolution no. 4 is 5 million shares. Out of the 5 million shares, you can either share your voting rights equally to 5 candidates for election as executive Directors so that you may vote 1 million shares to each candidate (vote for or against); or, give all of the 5 million votes to one particular candidate as executive Director (either for or against), or, 0.5 million shares to candidate A (either for or against), 1.5 million shares to candidate B (either for or against) as executive Director, the remaining 3 million shares to candidate C (either for or against) as executive Director, and no voting will be conducted for other candidates as executive Director, etc.

(iii) After you have allocated all the voting rights represented by all of the shares held by you to a certain number of candidates for executive Directors, you do not have further voting rights in respect of other candidates for executive Director. That is, the sum of all the voting rights you voted for or against the five candidates for election as executive Director shall not exceed the total number of voting rights represented by the shares held by you.

(iv) Please note with particular attention that, if the total number of votes you have exercised and allocated to a certain number of candidates for executive Director exceeds the total number of voting rights represented by the shares held by you, all your votes shall become void, and you will be deemed to be abstained from voting. If the total number of votes you have exercised and allocated to a certain number of candidates for executive Director is less than the total number of voting rights represented by the shares held by you, your votes are valid, and those votes not exercised will be deemed as being abstained from voting. For example, if you own 1 million shares, and five executive Directors should be elected in this election, the total number of votes as represented by your shares under resolution no. 4 will be 5 million: (a) if you have stated “5 million shares” in the column “for” (or “against”) in the cumulative voting system in favor of one particular candidate for executive Director, then your voting rights are fully utilized, and you do not have any further votes in relation to other candidates for executive Director. If you have stated the number of shares (other than 0 shares) in other corresponding columns under resolution no. 4, then all your votes in respect of resolution no. 4 will become void; or (b) if you have stated “0.5 million shares” in the column “for” (or “against”) in the cumulative voting system in favor of candidate A, and “0.5 million shares” in the column “for” (or “against”) in the cumulative voting system in favor of candidate B, then your votes as represented by such 1 million shares are valid, whilst the remaining 4 million shares which have not been allocated shall be deemed to have been abstained from voting.

(v) Where the total number of votes in favor of a candidate for executive Director exceeds one-half of the total number of shares with voting rights represented by Shareholders attending the general meeting (based on the non-cumulative number of shares) and the votes “for” exceed the votes “against”, that candidate will be elected as an executive Director.
