ANNOUNCEMENT ON PROGRESS RELATING TO
THE POSSIBLE ACQUISITION OF OPTI
 
 
Reference is made to the announcement of the Company dated July 20, 2011 in relation to the proposed transaction involving the acquisition of OPTI (the “Announcement”). Terms defined in the Announcement shall, unless the context otherwise requires, bear the same meaning herein.
 
The Board is pleased to announce that OPTI, the Purchaser and the Guarantor have entered into further Support Agreements with the Second Lien Noteholders, under which they have undertaken to vote in favour of the Plan of Arrangement. As at the date of this announcement, Second Lien Noteholders who collectively hold in aggregate approximately 82 per cent in principal amount of the Second Lien Notes have entered into Support Agreements. As stated in the Announcement, to approve the Plan of Arrangement, a majority in number of the voting Second Lien Noteholders, representing at least 66 2/3 percent in principal amount of the Second Lien Notes must vote in favour at the meeting of Second Lien Noteholders to be held in September 2011, and which is a condition precedent, amongst others, to complete the Transaction.
 
Shareholders of the Company and potential investors should note that the Transaction is subject to various conditions which may or may not be fulfilled. There is therefore no assurance that the Transaction will proceed and, if it proceeds, on what terms it may proceed. Shareholders of the Company and potential investors are reminded to exercise caution when dealing in the shares of the Company.
 
Further announcements will be made in accordance with the Listing Rules.
