FOURTH: Article IV.A of the Certificate is hereby amended and restated in its entirety to read as follows:

“A. Designation and Amount. The total number of shares of all classes of stock that the Corporation has authority to issue is 96,800,000, consisting of 50,000,000 shares of common stock, with a par value of $0.001 per share (the “Common Stock”), and 46,800,000 shares of preferred stock, with a par value of $0.001 per share (the “Preferred Stock”). Upon the filing and effectiveness (the “Effective Time”), pursuant to the General Corporation Law of the State of Delaware, of this Second Certificate of Amendment to the Fifth Amended and Restated Certificate of Incorporation of the Corporation, each three (3) shares of Common Stock either issued and outstanding or held by the Corporation in its treasury immediately prior to the Effective Time shall, automatically and without any action on the part of the respective holders thereof, be combined and converted into one (1) share of Common Stock (the “2014 Reverse Stock Split”). No fractional shares shall be issued in connection with the 2014 Reverse Stock Split. Any fractional shares of Common Stock that would otherwise exist due to the 2014 Reverse Stock Split shall be rounded down to the nearest whole share. Each certificate that immediately prior to the Effective Time represented shares of Common Stock (“Old Certificates”), shall thereafter represent that number of shares of Common Stock into which the shares of Common Stock represented by the Old Certificate shall have been combined, subject to the elimination of fractional share interests as described above. All Common Stock share and per share numbers in this Fifth Amended and Restated Certificate of Incorporation, as amended, are stated after giving effect to the 2014 Reverse Stock Split. Notwithstanding the foregoing, the par value of each share of the outstanding Common Stock shall not be adjusted in connection with the 2014 Reverse Stock

Split. The following is a statement of the designations and the powers, privileges and rights and the qualifications, limitations or restrictions thereof in respect of each class of capital stock of the Corporation.”
