A series of the Corporation’s Preferred Stock is designated as “Series A Preferred Stock” (the “Series A Preferred Stock”) and the maximum number of shares of Series A Preferred Stock shall be one and no more.

Section 2. Voting Rights; Generally. Subject to the other provisions of these Certificate of Incorporation (including the disparate votes per share provisions of the Series A Preferred Stock set forth in Sections 3, 4, and 5 below), each holder of Series A Preferred Stock shall have full voting rights and powers equal to the voting rights and powers of the holders of Common Stock, and shall be entitled to notice of any stockholders’ meeting in accordance with the Bylaws of the Corporation (as in effect at the time in question) and applicable law, and shall be entitled to vote, together with the holders of Common Stock, with respect to any question upon which holders of Common Stock have the right to vote, except as may be otherwise required by applicable law. Except as otherwise expressly provided herein, in the Corporation’s by-laws or as required by law, the holders of Series A Preferred Stock and Common Stock shall vote together and not as separate series or classes.

Section 3. Special Voting Rights of Series A Preferred Stock. Each share of Series A Preferred Stock shall be entitled to the number of votes and/or have voting power equal to one hundred ten percent (110%) of the issued and outstanding shares of Common Stock of the Corporation. If no shares of Common Stock are issued or outstanding, then each share of Series A Preferred Stock shall be entitled to that number of votes and/or have voting power equal to one hundred ten (110) shares of common stock. For purposes of calculating shares outstanding and entitled to vote on a particular matter, the shares outstanding shall be those outstanding on the record date for the determination of the stockholders entitled to vote on such matter or, if no such record date is established, the date such vote is taken or any written consent of stockholders is solicited.

The initial Series A Director shall be Choong Jeng Hew, who shall serve until the next annual meeting of stockholders and until his successor is elected and qualified.
