Cumulative voting of shares of Common Stock is prohibited. Shares of Common Stock may be issued for such consideration and for such corporate purposes as the Board of Directors of the Corporation may from time to time determine. In the event of voluntary or involuntary liquidation, distribution or sale of assets, dissolution or winding-up of the Corporation, the holders of the Common Stock shall be entitled to receive all the assets of the Corporation, tangible and intangible, of whatever kind available for distribution to stockholders, ratably in proportion to the number of shares of Common Stock held by each.

SEVENTH: The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. In furtherance and not in limitation of the powers conferred by the DGCL, the Board of Directors of the Corporation is expressly authorized to adopt, amend or repeal the Bylaws of the Corporation; provided, however, that the grant of such authority shall not divest the stockholders of the Corporation of the power, nor limit their power to adopt, amend or repeal the Bylaws of the Corporation.

EIGHTH: No director of the Corporation shall be personally liable to the Corporation or any of its stockholders for monetary damages for breach of fiduciary duty as a director involving any act or omission of any such director; provided, however, that the foregoing provision shall not eliminate or limit the liability of a director (a) for any breach of the director’s duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) under Section 174 of the DGCL, as the same exists or hereafter may be amended, supplemented, or replaced or (d) for any transaction from which such director derived an improper personal benefit.

If the DGCL is amended, supplemented, or replaced after the date of filing of this Certificate of Incorporation to authorize corporate action further limiting or eliminating the personal liability of directors, then the liability of a director of the Corporation, in addition to the limitation on personal liability provided for herein, shall be limited to the fullest extent permitted by such law.

Any repeal or modification of this Article EIGHTH shall be prospective only and shall not adversely affect any limitation on the personal liability of a director of the Corporation existing at the time of such repeal or modification.
