If you have sold or transferred all your shares in the capital of Sinobest Technology Holdings Ltd. (the “Company”) held through The Central Depository (Pte) Limited (“CDP”), you need not forward this Circular to the purchaser or transferee as arrangements will be made by CDP for a separate Circular to be sent to the purchaser or transferee.

The SGX-ST has granted the Company an extension of time until 28 February 2013 to meet the requirements to exit from the SGX-ST’s watch-list. Should the Company be unable to meet the requirements of Rule 1314 of the Listing Manual by 28 February 2013 or any extended timeline as approved by the SGX-ST, the SGX-ST may either remove the Company from its Official List, or suspend trading of the Shares with a view to removing the Company from its Official List. Please refer to the Section 4.7 of this Circular entitled “Rationale for the Proposed Acquisition” for further details of Rule 1314 of the Listing Manual.

In the event that the SGX-ST exercises its power to remove the Company from its Official List at such time, any exit alternative offered by the Company may or may not be reasonable and Shareholders may lose some or all of their investment in the Company. The SGX-ST assumes no responsibility for the contents of this Circular, including the correctness of any of the statements or opinions made or reports contained in this Circular. An application has been made to the SGX-ST for permission for the listing and quotation of the Consideration Shares, the Consolidated Shares and the Performance Shares on the Mainboard of the SGX-ST.
