PURPOSE

The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware, as amended from time to time (the “Delaware General Corporation Law”).

ARTICLE IV

CAPITAL STOCK

The total number of shares of all classes of capital stock that the Corporation is authorized to issue is 280,000,000 shares, consisting of (1) 200,000,000 shares of common stock, par value $0.01 per share (the “Common Stock”), and (2) 80,000,000 shares of preferred stock, par value $0.01 per share (the “Preferred Stock”). Except as otherwise provided in any Certificate of Designation (as defined below) relating to any series of Preferred Stock then outstanding, the number of authorized shares of any of the Common Stock or the Preferred Stock may be increased or decreased (but not below the number of shares of the Common Stock or the Preferred Stock, as the case may be, then outstanding) by the affirmative vote of the holders of shares of capital stock of the Corporation representing a majority in voting power of the outstanding capital stock entitled to vote on such increase or decrease irrespective of the provisions of Section 242(b)(2) of the Delaware General Corporation Law, and no vote of the holders of any of the Common Stock or the Preferred Stock voting separately as a class shall be required therefor. Upon the effectiveness of the Certificate of Conversion and this Certificate of Incorporation (the “Effective Time”), without any action required on the part of the Converting Entity, the Corporation or any former holder of limited liability company interests of the Converting Entity, (i) each Common Unit of the Converting Entity issued and outstanding immediately prior to the Effective Time will be converted into, and shall be deemed to be, 1.45320 issued and outstanding, fully paid and nonassessable shares of Common Stock and (ii) each Class B Preferred Unit of the Converting Entity issued and outstanding immediately prior to the Effective Time will be converted into, and shall be deemed to be, 1.55530 issued and outstanding, fully paid and nonassessable shares of Common Stock; provided, that in connection with the foregoing, the aggregate number of shares of Common Stock issued to each such former holder of Common Units or Class B Preferred Units, as applicable, will be rounded down to the nearest whole share of Common Stock.

Section A. Common Stock.

1. Ranking. The voting, dividend, liquidation and other rights of the holders of the Common Stock are subject to and qualified by the rights of the holders of any outstanding series of Preferred Stock.

2. Voting. Except as otherwise required by law and subject to the rights of the holders of any outstanding series of Preferred Stock, the holders of outstanding shares of Common Stock shall have the exclusive right to vote on the election and removal of directors and on all other matters submitted to a vote of the stockholders. Each share of Common Stock shall be entitled to one (1) vote. Notwithstanding any other provision of this Certificate of Incorporation to the contrary, the holders of Common Stock shall not be entitled to vote on any amendment to this Certificate of Incorporation (including any Certificate of Designation) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other outstanding series of Preferred Stock, to vote thereon pursuant to this Certificate of Incorporation (including any Certificate of Designation) or the Delaware General Corporation Law.

3. Dividends. Subject to applicable law and the rights of the holders of any outstanding series of Preferred Stock, dividends in securities, cash or other property of the Corporation may be declared and paid on the Common Stock out of the assets or funds of the Corporation lawfully available therefor, at the times and in the amounts as the Board in its discretion may determine, to the holders of the outstanding shares of Common Stock ratably in proportion to the number of shares of Common Stock.

4. Liquidation. In the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of the Corporation, after payment or provision for payment of the debts and other liabilities of the Corporation and of the preferential and other amounts, if any, to which the holders of Preferred Stock are entitled, if any, the holders of all outstanding shares of Common Stock will be entitled to receive, pari passu, the remaining assets of the Corporation available for distribution ratably in proportion to the number of shares of Common Stock.

Section B. Preferred Stock.

Shares of Preferred Stock may be issued from time to time in one or more series. The Board is hereby authorized, subject to any limitations prescribed by law but to the fullest extent permitted by law, to provide by resolution or resolutions from time to time for the issuance, out of the unissued shares of Preferred Stock, of one or more series of Preferred Stock, without stockholder approval, by filing a certificate pursuant to the applicable law of the State of Delaware (a “Certificate of Designation”) setting forth such resolution or resolutions and, with respect to each such series, establishing the number of shares to be included in such series, and fixing the voting powers, full or limited, or no voting power, of the shares of such series, and the designation, preferences and relative, participating, optional or other special rights, if any, of the shares of each such series, and any qualifications, limitations or restrictions thereof. The powers, designation, preferences and relative, participating, optional and other special rights of each series of Preferred Stock, and the qualifications, limitations and restrictions thereof, if any, may differ from those of any and all other series at any time outstanding.

Without limiting the generality of the foregoing, the resolution or resolutions providing for issuance of any series of Preferred Stock may provide that such series shall be superior to, rank equally with or be junior to any other series of Preferred Stock to the extent permitted by law.

Any shares of any series of Preferred Stock that may be redeemed, purchased or acquired by the Corporation may be reissued except as otherwise provided by law or by the terms of any Certificate of Designation for such series of Preferred Stock.

The directors of the Corporation shall not be required to be elected by written ballot unless the Bylaws so provide.

Section C. Newly-Created Directorships; Vacancies.

holders of any series of Preferred Stock having such right to elect additional directors are divested of such right pursuant to the provisions of this Certificate of Incorporation (including any Certificate of Designation), the terms of office of all such additional directors elected by the holders of such series, or elected to fill any vacancies resulting from the death, resignation, retirement, disqualification or removal of such additional directors, shall forthwith terminate, such additional directors shall automatically cease to be qualified and the total and authorized number of directors of the Corporation shall be reduced accordingly.
