The board of directors (the “ Board ”) of Telefield International (Holdings) Limited (the “ Company ”) is pleased to announce that on 9 August 2012 (after trading hours of the Stock Exchange of Hong Kong Limited (“ Stock Exchange ”)), the Company entered into a letter of intent (the “ Letter of Intent ”) with a third party independent of and not connected with the Company and its subsidiaries and its connected persons (as defined in the Listing Rules) (the “ Target Company ”) in relation to the proposed subscription by the Company (or its subsidiary) of such number of new shares of the Target Company as representing more than 50% per cent. of the enlarged issued share capital of the Target Company at a tentative total consideration of HK$15 million (subject to, among others, the satisfactory completion of a due diligence review of the Target Company by the Company and the execution of a formal agreement between the parties) (the “ Proposed Subscription ”).

The Group is principally engaged in providing electronics manufacturing services (“ EMS ”) and operating distribution businesses. By the end of 2010, the Group’s EMS business had expanded into niche markets for production of health care and baby care electronic product and the Group remains keen on developing products with high-growth potential. The Target Company, through its subsidiaries, is a distributor of a wide range of wireless products and peripherals and a provider of end-to-end wireless connectivity solutions and high level technical support in Asia and other territories. The directors of the Company believes that the proposed acquisition of the majority shareholding interest in the Target Company would provide an opportunity for the Company to acquire additional technical expertise and business opportunities in developing high-end niche communication products.
