THIRD:       The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the DGCL, as it now exists or may hereafter be amended and supplemented.

FOURTH:   The Corporation is authorized to issue two classes of stock to be designated, respectively, “Common Stock” and “Preferred Stock.”  The total number of shares of capital stock which the Corporation shall have authority to issue is 105,000,000.  The total number of shares of Common Stock that the Corporation is authorized to issue is 100,000,000, having a par value of $0.01 per share, and the total number of shares of Preferred Stock that the corporation is authorized to issue is 5,000,000, having a par value of $0.01 per share.

FIFTH:       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 are as follows:

The number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the DGCL.

Preferred Stock may be issued from time to time in one or more series, each of such series to have such terms as stated or expressed herein and in the resolution or resolutions providing for the issue of such series adopted by the Board of Directors as hereinafter provided.

Authority is hereby expressly granted to the Board of Directors from time to time to issue the Preferred Stock in one or more series, and in connection with the creation of any such series, by adopting a resolution or resolutions providing for the issuance of the shares thereof and by filing a certificate of designations relating thereto in accordance with the DGCL, to determine and fix the number of shares of such series and such voting powers, full or limited, or no voting powers, and such designations, preferences and relative participating, optional or other special rights, and qualifications, limitations or restrictions thereof, including without limitation thereof, dividend rights, conversion rights, redemption privileges and liquidation preferences, as shall be stated and expressed in such resolutions, all to the fullest extent now or hereafter permitted by the DGCL.  Without limiting the generality of the foregoing, the resolution or resolutions providing for the issuance of any series of Preferred Stock may provide that such series shall be superior or rank equally or be junior to any other series of Preferred Stock to the extent permitted by law.

The number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the DGCL.

SIXTH:        The personal liability of the directors of the Corporation, to the Corporation or its stockholders for monetary damages for breach of his or her fiduciary duty as director, is hereby eliminated to the fullest extent permitted by the DGCL, as the same may be amended and supplemented.  Any amendment, repeal or modification of this Article Sixth, or the adoption of any provision of the Amended and Restated Certificate of Incorporation inconsistent with this Article Sixth, shall not adversely affect any right or protection of a director of the Corporation existing immediately prior to such amendment, repeal or modification.  If the DGCL is amended after approval by the stockholders of this Article Sixth to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL as so amended.

SEVENTH:   The Corporation shall, through the Bylaws or otherwise, to the fullest extent permitted by the DGCL, as the same exists or may hereafter be amended and supplemented, indemnify, advance expenses and hold harmless any person who was or is a director or officer of the Corporation or its subsidiaries.  The Corporation may, by action of the Board of Directors, provide rights to indemnification and to advancement of expenses to such other employees or agents of the Corporation or its subsidiaries to such extent and to such effect as the Board of Directors shall determine to be appropriate and authorized by the DGCL.  Any amendment, repeal or modification of this Article Seventh shall not adversely affect any rights or protection existing hereunder immediately prior to such repeal or modification.  Notwithstanding the foregoing, the Corporation shall be required to indemnify a person in connection with any action, suit or proceeding, whether civil, criminal, administrative or investigative (each a “Proceeding”), initiated by such person only if the Proceeding was authorized in the specific case by the Board of Directors.

EIGHTH:     From time to time any of the provisions of this Amended and Restated Certificate of Incorporation may be amended, altered, changed or repealed, and other provisions authorized by the laws of the State of Delaware at the time in force may be added or inserted in the manner and at the time prescribed by said laws, and all rights at any time conferred upon the stockholders of the Corporation by this Amended and Restated Certificate of Incorporation are granted subject to the provisions of this Article Eighth.

NINTH:     In furtherance and not in limitation of the rights, powers, privileges and discretionary authority granted or conferred by the DGCL or other statutes or laws of the State of Delaware, the Board of Directors is expressly authorized to make, alter, amend or repeal the Bylaws, without any action on the part of the stockholders, but the stockholders may make additional Bylaws and may alter, amend or repeal any Bylaw whether adopted by them or otherwise.  The Corporation may in its Bylaws confer powers upon its Board of Directors in addition to the foregoing and in addition to the powers and authorities expressly conferred upon the Board of Directors by applicable law.
