Dear Sir/Madam,

The purpose of this circular is to provide you with further information on the proposed resolution at an extraordinary general meeting of the Company to be held at The Lily Room of Ramada Hong Kong Hotel at 3rd Floor, 308 Des Voeux Road West, Hong Kong on Friday, 10 May 2013 at 10:00 a.m. and to give you notice of the EGM at which the resolution will be proposed to consider and, if thought fit, approve such matters.

LETTER FROM THE BOARD

Pursuant to article 58 of the Articles, any one or more shareholders holding at the date of deposit of the requisition not less than one-tenth of the paid up capital of the Company carrying the right of voting at general meetings of the Company shall at all times have the right, by written requisition to the Board to require an extraordinary general meeting to be called by the Board for the transaction of any business specified in such requisition within 21 days of such deposit.

The Company received the Requisition dated 12 March 2013 purportedly signed by Mr. Jeong Keun Hae as attorney for Mr. Park Seung Ho and by Mr. Jeong Keun Hae as attorney for Skyline Merit Limited (granted by its sole director, Ms. Choi Soo In) requesting the Board to convene an extraordinary general meeting in accordance with the Articles. The Requisition requested the convention of an extraordinary general meeting for considering and, if thought fit, passing the following ordinary resolution:—

“THAT Mr. Jeong Keun Hae and Mr. Mark Wayne Allers each be hereby appointed as an director of the Company with immediate effect.”

(2) REASON FOR THE PROPOSAL APPOINTMENT

The Requisition Shareholders have not provided reasons and/or any information and/or grounds in respect of the said proposed appointment of directors. Accordingly the Board is not able to provide you with any reason and/or any information and/or grounds in respect of the said proposed appointment of directors for consideration.

As a result of the lack of information and details provided by the Requisition Shareholders in relation to the proposed appointment, the Board has made efforts to obtain further information from the Requisition Shareholders by writing to their legal representatives and requesting the proposed directors to attend an interview with the Nomination Committee. Although the said interview was scheduled at 5:00 p.m. on 21 March 2013, the proposed directors neither showed up in the interview nor provided any explanation for their failure to attend the interview. Accordingly, the Board is unable to give opinions on their suitability to become a director of the Company.

Further, pursuant to the duty of care of the directors of the Company under the relevant provisions of the Listing Rules, the Corporate Governance Code and its Recommended Best Practices, to ensure effective communication with Shareholders and to ensure that the Shareholders’ views are communicated to the Board as a whole, and to uphold the internal control system and corporate governance of the Company and to protect the interest of the Shareholders as a whole, the Board has made another request to the Requisition Shareholders and/or their legal representatives of the Requisition Shareholders to attend a meeting with the Audit Committee of the Company, all three members of which are independent non-executive directors (“INEDs”), so that the Requisition Shareholders and/or their legal representatives can access directly to the INEDs for the exercise of the right of representation, both oral and written, concerning the Requisition. Although the said meeting was scheduled at 5:00 p.m. on 22 March 2013, the Requisition Shareholders and/or their legal representatives neither showed up in the interview nor provided any explanation for their failure to attend the said meeting. Accordingly, the Board is unable to obtain further information from the Requisition Shareholders.

LETTER FROM THE BOARD

The Board further notes that according to Code Provision E.1.1 of Appendix 14 of the Listing Rules that “each substantially separate issue at a general meeting, a separate resolution should be proposed by the chairman of that meeting. Issuers should avoid “bundling” resolutions unless they are interdependent and linked forming one significant proposal. Where the resolutions are “bundled”, issuers should explain the reasons and material implications in the notice of meeting.” Therefore, the Board alerts Shareholders that the proposed resolution may breach the Listing Rules.

In light of the Directors’ request made to the solicitor representing the Requisition Shareholders, the Requisition Shareholders have furnished the Board with resume of each proposed director, however, the Requisition Shareholders cannot provide the Company with the consent of the two proposed directors for disclosure of their resumes in this circular. The Company eventually obtained the consent from Mr. Mark Wayne Allers. The Company has included the resume of Mr. Mark Wayne Allers in Appendix I — Particulars of Directors for Appointment” of this circular. Further, despite of various request made by the Company, Mr. Jeong Keun Hae, one of the proposed directors has not given the Company his consent for the inclusion of his resume in this circular for shareholders’ consideration as at the Latest Practicable Date. In light of this the Company is unable to disclose the resume of Mr. Jeong Keun Hae for the reason of protection of personal data. At the request of the Company, the solicitor representing the Requisition Shareholders has provided the confirmation signed by the two proposed directors on 14 March 2013, which are annexed in “Appendix I — Particulars of Directors for Appointment” of this circular. However, the Board alerts Shareholders that the content of the said Appendix I is not verified by the Board. The Board notes that the Requisition Shareholders and/or both proposed directors and/or their legal representatives had not provided any documents for the Board’s verification in relation to their respective academic qualifications and working experience. As at the Latest Practicable Date for the said reason, the Board is unable to perform due diligence on certain particulars of the proposed directors in order to perform its duty of care under the Listing Rules, Corporate Governance Code and its Recommended Best Practices despite of various requests made by the Company.

Mr. Jeong Keun Hae (“Mr. Jeong”)

Based on the disclosure made by Mr. Jeong in the confirmation, as annexed in “Appendix I — Particulars of Directors for Appointment” of this circular, on or about 13 March 2013, Mr. Jeong has not held any other positions with the Company or any of its subsidiaries, and he did not hold any other directorships in other listed companies in the last three years. Mr. Jeong has not disclosed that he has any other major appointments and professional qualifications.

The length of service with the Company has not been proposed by the Requisition Shareholders. Mr. Jeong may enter into service agreement with the Company and will be subject to retirement by rotation and re-election at the annual general meetings of the Company in accordance with the Company’s Articles. The Requisition Shareholders have proposed remuneration for each of the proposed directors to be HK$20,000 per month and the Requisition Shareholders have not provided any basis for the proposed remuneration.

• (iv) there are no other matters that need to be brought to the attention of the Shareholders of the Company.

Mr. Mark Wayne Allers (“Mr. Allers”)

Based on the disclosure made by Mr. Allers in the confirmation, as annexed in “Appendix I — Particulars of Directors for Appointment” of this circular, on or about 13 March 2013, Mr. Allers has not held any other positions with the Company or any of its subsidiaries, and he did not hold any other directorships in other listed companies in the last three years. Mr. Allers has not disclosed that he has any major appointments and professional qualifications.

The length of service with the Company has not been proposed by the Requisition Shareholders. Mr. Allers may enter into service agreement with the Company and will be subject to retirement by rotation and re-election at the annual general meetings of the Company in accordance with the Company’s Articles. The Requisition Shareholders have proposed remuneration for each of the proposed directors to be HK$20,000 per month and the Requisition Shareholders have not provided any basis for the proposed remuneration.

Based on the disclosure made by Mr. Allers in the confirmation on or about 13 March 2013, as annexed in “Appendix I — Particulars of Directors for Appointment” of this circular as at the date of the confirmation:

• (i) Mr. Allers has no interests in shares of the Company within the meaning of Part XV of the SFO as stated in page 2 of his confirmation;

– 5 –

LETTER FROM THE BOARD

• (iii) there is certain other information which is required to be disclosed pursuant to the requirements of Rule 13.51(2)(h) — (v) of the Listing Rules as stated in page 4 of his confirmation and the Company has sought further information/clarification from Mr. Allers on such but Mr. Allers has not provided further clarification; and

• (iv) there are no other matters that need to be brought to the attention of the Shareholders of the Company.

Having considered the resume of each proposed director, and assuming the information provided by them are true and accurate, the Board further draws the Shareholders’ attention to the fact that both of the proposed directors have not held any directorship in listed public companies (in the past 3 years). In light of this, the Board is not in a position to give opinions on the ability and/or capacity of the proposed directors to “demonstrate a standard of competence commensurate with” their positions as listed company directors as required by Rule 3.09 of the Listing Rules.

(3) FACTORS TO BE CONSIDERED

For reasons set out in the section entitled “Reason for the Proposal Appointment” above, the Directors would like to strongly emphasize and alert Shareholders that the Board is not in a position to give opinions on the ability and/or capacity of the proposed directors to “demonstrate a standard of competence commensurate with” their positions as listed company directors as required by the Listing Rules. Further, the Board reiterates that the respective academic qualifications and working experience of the proposed directors are not being verified. Last but not the least, the proposed resolution may breach the Listing Rules due to the “bundling” of appointment of two directors in one single resolution.

Accordingly, the Board recommends the Shareholders to give serious thoughts and considerations before casting their votes to the resolution as set out in the notice of the EGM.

(4) EGM AND VOTING ARRANGEMENT

The EGM will be held for considering and, if thought fit, passing the ordinary resolution to approve the resolution as set out in the notice of the EGM.

Pursuant to Rule 13.39(4) of the Listing Rules, any vote of shareholders at a general meeting must be conducted by way of poll. The chairman of the meeting will therefore demand a poll for every resolution put to the vote of the EGM in accordance with the Articles. The results of the poll shall be deemed to be the resolutions of the general meeting in which the poll was demanded or required and the poll results will be published on the websites of the Stock Exchange and the Company after the EGM.
