ISSUE OF THE CONVERSION SHARES UNDER THE GENERAL MANDATE Based on the principal amount of US$46,800,000 (subject to the RMB Cap Amount) of the Convertible Bonds and the initial Conversion Price of HK$0.40 per Conversion Share, the Company will issue 906,750,000 Conversion Shares upon full exercise of the conversion rights attached to the Convertible Bonds, representing: (i) (ii) approximately 7.47% of the issued share capital of the Company as at the date of the Subscription Agreement; and approximately 6.95% of the enlarged issued share capital of the Company (assuming that there is no change in the issued share capital of the Company other than the issue of the Conversion Shares since the date of the Subscription Agreement up to the date of full conversion of the Convertible Bonds). The Conversion Shares will be issued and allotted under the General Mandate granted to the Directors at the Company s annual general meeting held on 27 May 2015 to issue, allot and deal with no more than 2,429,114,609 Shares. As at the date of this announcement, save for the proposed issue of the Conversion Shares upon exercise of the conversion rights attached to the Convertible Bonds, the Company has not utilised the General Mandate. As such, the issue of the Convertible Bonds and the issue of the Convertible Shares upon exercise of the conversion rights attached to the Convertible Bonds will not be subject to the Shareholders further approval. Application will be made by the Company to the Listing Committee of the Stock Exchange for the granting of the approval for the listing of, and permission to deal in, the Conversion Shares to be issued upon exercise of the conversion rights attached to the Convertible Bonds. REASONS FOR THE ISSUE OF THE CONVERTIBLE BONDS The Directors consider that the issue of the Convertible Bonds represents an opportunity to raise additional funds for the Company s general working capital. The Directors also consider that the issue of the Convertible Bonds is an appropriate means through which the Company can raise funds as it provides the Company with funding without immediate dilution of the interests of the existing Shareholders notwithstanding that their interests will be diluted if the Convertible Bonds are converted in the future. In addition, upon conversion of the Convertible Bonds, it is expected that the shareholding structure and the capital base of the Company would be enlarged and strengthened, which will benefit the future growth and development of the Group s business. Taking into account of the above, the Directors consider that the terms and conditions of the Subscription Agreement and the Convertible Bonds were negotiated on an arm s length basis and agreed on normal commercial terms between the Company and the Investor. The Directors also consider that the terms and conditions of the Subscription Agreement and the Convertible Bonds are fair and reasonable and the entering into the Subscription Agreement and the issue of the Convertible Bonds would be in the interests of the Company and its Shareholders as a whole. 9
