PART II -- RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25(b), the following should
be completed. (Check box if appropriate) |_|

              (a) The reason described in reasonable detail in Part III of this
              form could not be eliminated without unreasonable effort or
              expense;

              (b) The subject annual report, semi-annual report, transition
              report on Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form
              N-CSR, or portion thereof, will be filed on or before the
              fifteenth calendar day following the prescribed due date; or the
              subject quarterly report or transition report on Form 10-Q or
              subject distribution report on Form 10-D, or portion thereof, will
              be filed on or before the fifth calendar day following the
              prescribed due date; and

              (c) The accountant's statement or other exhibit required by Rule
              12b-25(c) has been attached if applicable.





PART III -- NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR,
N-CSR, or the transition report or portion thereof, could not be filed within
the prescribed time period. (Attach extra Sheets if Needed)

      The registrant is unable to file its Quarterly Report on Form 10-Q for the
      quarter ended March 31, 2011, within the prescribed time period due to an
      ongoing investigation by the Special Committee of the registration's Board
      of Directors into possible discrepancies concerning the registrant's
      banking statements identified by the registrant's auditors in the course
      of their audit of the registrant's consolidated financial statements for
      the fiscal year ended December 31, 2010 (please refer to the registrant's
      Current Report on Form 8-K filed on March 31, 2011). The registrant and
      its advisors are working expeditiously to resolve the issues discovered
      during the audit, but the registrant, at this time, is unable to determine
      when it will file its Quarterly Report on Form 10-Q for the quarter ended
      March 31, 2011.

PART IV -- OTHER INFORMATION

(1) Name and telephone number of person to contact in regard to this
notification

Heung Sang Fong, Chief Financial Officer              + 86-755-8149 9969
(Name)                                            (Area Code) (Telephone Number)

(2) Have all other periodic reports required under Section 13 or 15(d) of the
Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of
1940 during the preceding 12 months or for such shorter period that the
registrant was required to file such report(s) been filed ? If answer is no,
identify report(s). Yes |_| No |X|

     Annual Report on Form 10-K for the fiscal year ended December 31, 2010

(3) Is it anticipated that any significant change in results of operations from
the corresponding period for the last fiscal year will be reflected by the
earnings statements to be included in the subject report or portion thereof?
Yes |_|?No |_|

If so, attach an explanation of the anticipated change, both narratively and
quantitatively, and, if appropriate, state the reasons why a reasonable estimate
of the results cannot be made.

         Given that the investigation of possible discrepancies concerning the
         registrant's banking statements is ongoing, the registrant cannot at
         this time predict whether that investigation will require any
         adjustments to the registrant's financial statements, and if so,
         whether such adjustments will be material. As a result, the registrant
         is unable at this time to reasonably estimate whether any significant
         change in its results of operations for the quarter ended March 31,
         2011 will be reflected by the earnings statements to be included in its
         Quarterly Report of Form 10-Q for the quarter ended March 31, 2011.

                  (Name of Registrant as Specified in Charter)
