CHARACTERISTICS OF GEM

GEM has been positioned as a market designed to accommodate companies to which a high investment risk may be attached than other companies listed on the Exchange. Prospective investors should be aware of the potential risks of investing in such companies and should make the decision to invest only after due and careful consideration. The greater risk profile and other characteristics of GEM mean that it is a market more suited to professional and other sophisticated investors.

Given the emerging nature of companies listed on GEM, there is a risk that securities traded on GEM may be more susceptible to high market volatility than securities traded on the Main Board and no assurance is given that there will be a liquid market in the securities traded on GEM.

LETTER FROM THE BOARD

The Repurchase Mandate allows the Company to make repurchase only during the period from the date of the passing of the relevant resolution until the earliest of the conclusion of next annual general meeting of the Company, the date by which the next annual general meeting of the Company is required by the articles of association of the Company, or any applicable law of the Cayman Islands to be held and the date upon which the Repurchase Mandate is revoked or varied by an ordinary resolution of shareholders of the Company in general meeting.

In accordance with the GEM Listing Rules, the Company is required to send to the Shareholders an explanatory statement containing all information reasonably necessary to enable them to make an informed decision on whether to vote for or against the ordinary resolution to renew the grant to the Directors of the Repurchase Mandate. Such explanatory statement is set out in Appendix I to this circular.

REFRESHMENT OF THE SCHEME LIMIT

At present, the Company has a Share Option Scheme which was conditionally adopted on 28 July 2010 and became unconditional on 7 August 2010. The Company had also adopted the Previous Scheme on 22 November 2001 which was subsequently terminated on 7 August 2010. However, the provisions of the Previous Scheme shall remain in force to the extent necessary to give effect to the exercise of any options granted prior thereto or as may be required in accordance with the provisions of the Previous Scheme. Apart from the Share Option Scheme and the Previous Scheme, as at the Latest Practicable Date, the Company did not have any other share option schemes.

Under the GEM Listing Rules and the Share Option Scheme:

• (i) the Existing Scheme Limit so refreshed must not exceed 10% of the issued share capital of the Company at the date of the approval of the Refreshed Scheme Limit by the Shareholders;

• (ii) all options granted under the Share Option Scheme and any other share option schemes of the Company (including those exercised, outstanding, cancelled or lapsed in accordance with the Share Option Scheme and any other share option schemes of the Company) prior to the approval of such Refreshed Scheme Limit shall not be counted for the purpose of calculating whether the Refreshed Scheme Limit has been exceeded and the total number of Shares subject to the Refreshed Scheme Limit;

• (iii) Notwithstanding the above, the maximum number of Shares which may be issued upon exercise of all outstanding options granted and yet to be exercised under the share option schemes of the Company shall not exceed 30% (or such higher percentage as may be allowed under the GEM Listing Rules) of the total number of Shares in issue from time to time.

• 5 -

LETTER FROM THE BOARD

Under the Existing Scheme Limit, a total of 172,994,311 options can be granted. On 9 September 2010, there were 172,992,000 options granted under the Share Option Scheme and no options has lapsed or cancelled since granting. As at the Latest Practicable Date, these options are still outstanding and exercisable. In addition to 89,825,000 options previously granted under the Previous Scheme, therefore, as at the Latest Practicable Date, there were a total of 262,817,000 outstanding and unexercised options granted under the Share Option Scheme and the Previous Scheme, representing approximately 12.73% of the existing issued share capital of the Company. Under the Existing Scheme Limit, there are still 2,311 options that can be granted.

The Board believes that the Refreshed Scheme Limit will give more flexibility for the Company to grant options to the Participants to reward and motivate them to strive for the future developments and success of the Group, which shall be in the interests of the Company and the Shareholders as a whole.

Assuming that no Shares are issued or repurchased by the Company from the Latest Practicable Date up to the AGM, the Company will have 2,065,307,117 Shares in issue as at the date of the AGM. The Refreshed Scheme Limit, if approved by the Shareholders at the AGM, will allow the Company to issue, upon exercise of options under the Share Option Scheme, a maximum of 206,530,711 Shares, representing 10% of the issued share capital of the Company as at the date of approval of the Refreshed Scheme Limit.

The Refreshed Scheme Limit is conditional upon the approval of such resolution at the AGM and upon granting by the Stock Exchange of the listing of and permission to deal in the Shares to be issued upon the exercise of the options be granted under the Refreshed Scheme Limit.

EXPLANATORY STATEMENT

APPENDIX I

The following is the explanatory statement required to be sent to the Shareholders under the GEM Listing Rules in connection with the proposed general mandate for repurchases of Shares to be passed by the Shareholders by an ordinary resolution at the Annual General Meeting.

(1) Reasons for Repurchases

The Directors believe that it is in the best interest of the Company and its Shareholders for the Directors to have a general authority from Shareholders to enable the Company to repurchase Shares in the market. Repurchases of Shares will only be made when the Directors believe that such a repurchase will benefit the Company and its Shareholders. Such repurchases may, depending on the market conditions and funding arrangements at the time, lead to an enhancement of the net value of the Company and its assets and/or its earnings per Share.

(2) Funding of Repurchases

The Directors wish to state that repurchases pursuant to the Repurchase Mandate would be financed entirely from the Company’s available cash flow or working capital facilities and any repurchases will only be funded out of funds of the Company legally available for the purposes in accordance with its memorandum of association and articles of association and the laws of the Cayman Islands.

The Company may not repurchase its own Shares on the Stock Exchange for a consideration other than cash or for settlement otherwise than in accordance with the trading rules of the Stock Exchange from time to time.

(3) Impact of Repurchases

There might be a material adverse impact on the working capital or gearing position of the Company (as compared with the position disclosed in its latest published audited accounts for the year ended 31 March 2011) in the event that the proposed repurchases were to be carried out in full at any time during the proposed repurchase period. However, the Directors do not propose to exercise the Repurchase Mandate to such an extent as would, in the circumstances, have a material adverse effect on the working capital requirements of the Company or the gearing levels which in the opinion of the Directors are from time to time appropriate for the Company.

(4) Exercise of the Repurchase Mandate

As at the Latest Practicable Date, the authorised share capital of the Company was US$160,000,000 divided into 16,000,000,000 Shares, of which 2,065,307,117 Shares were in issue. There were 262,817,000 outstanding options under the Company’s share option schemes, to subscribe up to 262,817,000 Shares.

On the basis of 2,065,307,117 existing Shares in issue as at the Latest Practicable Date and assuming that no Shares are repurchased or further issued, the Directors would be authorised to repurchase up to 206,530,711 Shares which represent 10 per cent. of the 2,065,307,117 existing Shares in issue as at the Latest Practicable Date.

EXPLANATORY STATEMENT

APPENDIX I

(5) Disclosure of Interest

Rule 13.11(2) of the GEM Listing Rules prohibit a company from knowingly repurchasing its shares on GEM from a connected person (as defined in the GEM Listing Rules) and a connected person is prohibited from knowingly selling his/her/its shares to the company on GEM.

None of the Directors and, to the best of their knowledge, having made all reasonable enquiries, none of their respective associates, have any present intention, if the Repurchase Mandate is approved by the Shareholders of the Company, to sell any Shares to the Company or its subsidiaries.

As at the Latest Practicable Date, no connected persons (as defined in the GEM Listing Rules) of the Company have notified the Company that they have a present intention to sell Shares to the Company, or have undertaken not to do so, in the event that the Company is authorised to make repurchases of the Shares.

(6) Directors’ Undertaking

The Directors have undertaken to the Stock Exchange that they will exercise the power of the Company to make repurchases pursuant to the proposed resolution, if granted, in accordance with the GEM Listing Rules, the applicable laws of the Cayman Islands and the regulations set out in the memorandum and articles of association of the Company.

(7) Share Repurchase made by the Company

No repurchases of Shares have been made by the Company during the six months (whether on GEM or otherwise) preceding the Latest Practicable Date.

(8) Takeovers Code Consequences

If as a result of a repurchase of Shares, a Shareholder’s proportionate interest in the voting rights of the Company increases, such increase will be treated as an acquisition for the purpose of the Takeovers Code. As a result, a Shareholder, or a group of Shareholders acting in concert (within the meaning under the Takeovers Code), depending on the level of increase of the Shareholder’s interest, could obtain or consolidate control of the Company and become obliged to make a mandatory offer in accordance with Rule 26 of the Takeovers Code.

As at the Latest Practicable Date, to the best of the knowledge and belief of the Directors, Mr. Xu Shengheng, holds 608,319,000 Shares, representing approximately 29.45% of the issued share capital of the Company. Ms. Luk Hoi Man, spouse of Mr. Xu Shengheng, also holds 702,000 Shares, representing approximately 0.03% of the issued share capital of the Company. In the event that the Directors exercised in full the power to repurchase Shares of the Company in accordance with the terms of the Repurchase Mandate, Mr. Xu Shengheng and Ms. Luk Hoi Man proportionate interests in the voting rights of the Company would be increased to approximately 32.77% in aggregate and they would be obliged to make a mandatory offer under Rule 26 of the Takeovers Code in this respect.

• 9 -

EXPLANATORY STATEMENT

APPENDIX I

Save as aforesaid, the Directors are not aware of any consequences which would arise under the Takeovers Code as a consequence of any repurchase pursuant to the Repurchase Mandate. Moreover, the Directors have no present intentions to exercise the Repurchase Mandate to such an extent that the obligation to make a general offer on the part of Mr. Xu Shengheng and Ms. Luk Hoi Man will be triggered under the Takeovers Code. Assuming that there is no further issue of the Shares between the Latest Practicable Date and the date of repurchase, the exercise of the Repurchase Mandate in full will not result in the level of shareholdings in the Company being held by the public below the minimum public float as required under the GEM Listing Rules.

(9) Share Prices

The highest and lowest prices at which the Shares were traded on GEM during each of the twelve months from 1 June 2010 to 31 May 2011 and the period from 1 June 2011 up to the Latest Practicable Date were as follows:
