This Amendment No. 6 (the “Amendment”) amends the Schedule 13D filed on April 19, 2010, as amended by Amendment No. 5 to the Schedule 13D filed on March 1, 2017 (as amended, the “Prior Filing”) by the Reporting Persons relating to the common stock, par value $0.001 per share (the “Shares”), of TIM Technologies, Inc.

Item 4 of the Prior Filing is hereby amended and restated in its entirety as follows:

On August 13, 2018 (the “Relevant Date”), Su Sih (BVI) Limited (“Su Sih”) executed a sale of 3,622,500 Shares to J.P. Morgan Securities LLC in reliance on Rule 144 under the Act.

As a result of the transactions described herein, none of the Reporting Persons holds the Shares with any purpose, or with the effect, of changing or influencing the control of the Company, or in connection with or as a participant in any transaction having that purpose or effect.

As a result of the transactions described herein, Mr. TANG Hsiang Chien will cease to be the beneficial owner of more than five percent of the Shares. The filing of this Amendment No. 6 constitutes an exit filing for Mr. TANG Hsiang Chien.  

Except as set forth in this Amendment, Mr. TANG Hsiang Chien and Su Sih (BVI) Limited have no present plans or proposals that relate to or would result in any of the transactions described in subparagraphs (a) through (j) of item 4 of Schedule 13D. Following the sale, Mr. TANG Hsiang Chien and Su Sih (BVI) Limited may from time to time review their investment and, subject to the approval of the other directors of Su Sih (BVI) Limited (as set forth in Schedule A to the Prior Filing), decide (i) to acquire additional securities of the Company, through open market purchases, privately negotiated transactions or otherwise, or (ii) to dispose of all or a portion of the securities of the Company owned by it in the open market, in privately negotiated transactions or otherwise. Any such acquisition or disposition or other transaction would be made in compliance with all applicable laws and regulations.

Pursuant to the Articles of Association of Su Sih (BVI) Limited, any acquisition by Su Sih (BVI) Limited of assets, or any sale, transfer, lease, exchange or other disposition of Su Sih (BVI) Limited assets must be approved by all directors of Su Sih (BVI) Limited. As a result, all potential future dispositions of the Shares beneficially owned by Su Sih (BVI) Limited will require the approval of all of its directors. As of the Relevant Date, and as set forth in Schedule C hereto, the directors of Su Sih (BVI) Limited were executors appointed by Mr. Hsiang Tang, Mr. Henry Tang, Mr. Tang Chung Yen, Tom and Ms. Tang Ying Ming, Mai.
