Item 6 of the Previous Filings included this paragraph:

“The Reporting Persons believe that DB may have exercised certain rights in respect of the Charged Shares pursuant to the Security Agreement. As of the date hereof, the Reporting Persons are only aware of the sale of 391,199 of the Charged Shares by DB for a total consideration of US$1,151,625.80 on 1 & 2 March 2010 and have not yet been able to verify whether DB has taken any other actions in respect of the Charged Shares. DB has filed a Schedule 13G on February 10, 2012 (the “DB Schedule 13G”) in respect of 3,380,079 Shares out of the 3,780,600 Charged Shares. As of the date hereof, the Reporting Persons are of the view that the Secured Obligations have already been settled. S&T is seeking clarification of the basis on which DB has claimed beneficial ownership in the Charged Shares as disclosed in the DB Schedule 13G.”

The foregoing paragraph is hereby deleted and replaced in its entirety as follows:

“On or around February 2010, Grande Holdings defaulted on its obligations to DB, after which DB exercised certain of its rights in respect of the Charged Shares pursuant to the Security Agreement. On March 1, 2010, DB disposed or caused the disposal of 3,900 Charged Shares at $2.2397 per share; and on March 2, 2010, DB disposed or caused the disposal of 387,299 Charged Shares at $2.955 per share. The said disposals were handled by DB.

On March 26, 2013, DB and S&T agreed on a settlement in respect of the Security Agreement pursuant to which DB has agreed (i) that all of S&T’s obligations under the Security Agreement have been discharged, (ii) to release its fixed security interest over the remaining Charged Shares (totaling 3,389,401 shares) and return and re-assign the remaining Charged Shares to S&T. As of April 2, 2013, the remaining Charged Shares have been re-assigned and returned to the possession of S&T.”
