ARTICLE V

BOARD OF DIRECTORS

Section 5.1 Number. Except as otherwise provided for or fixed pursuant to the provisions of Article IV hereof (including any Preferred Stock Designation), the Board of Directors shall consist of not fewer than three nor more than 15 directors, the exact number to be determined from time to time solely by resolution adopted by the affirmative vote of a majority of the directors then in office; provided, however, that it is not less than one-third of the total number of directors then authorized.

Section 5.2 Classification; Vacancies; Removal.

(a) The Board of Directors (other than those directors elected by the holders of any series of Preferred Stock provided for or fixed pursuant to the provisions of Article IV hereof (including any Preferred Stock Designation) (the “Preferred Stock Directors”)) shall be divided into three classes, as nearly equal in number as possible, designated Class I, Class II and Class III. Class I directors shall initially serve until the first annual meeting of stockholders following the effectiveness of this Section 5.2; Class II directors shall initially serve until the second annual meeting of stockholders following the effectiveness of this Section 5.2; and Class III directors shall initially serve until the third annual meeting of stockholders following the effectiveness of this Section 5.2. Commencing with the first annual meeting of stockholders following the effectiveness of this Section 5.2 and ending with third annual meeting of stockholders following the effectiveness of this Section 5.2, directors of each class the term of which shall then expire shall be elected to hold office for a three-year term and until the election and qualification of their respective successors in office. Beginning with the fourth annual meeting of stockholders following the effectiveness of this Section 5.2, directors of each class the term of which shall then expire shall be elected to hold office for a one-year term and until the election and qualification of their respective successor in office. In case of any increase or decrease, from time to time prior to the sixth annual meeting of stockholder following the effectiveness of this Section 5.2, in the number of directors (other than Preferred Stock Directors), the number of directors in each class shall be apportioned as nearly equal as possible.

(b) Subject to the rights of the holders of any outstanding series of Preferred Stock, and unless otherwise required by law, newly created directorships resulting from any increase in the authorized number of directors and any vacancies in the Board of Directors resulting from death, resignation, retirement, disqualification, removal from office or other cause shall be filled solely by the affirmative vote of a majority of the remaining directors then in office and entitled to vote thereon, even though less than a quorum of the Board of Directors, or by the sole remaining director; provided, however, that so long as Lone Star Fund VIII (U.S.), L.P., a Delaware limited partnership, and its Affiliates (as defined in Section 11.5) (collectively, the “Lone Star Entities”) beneficially own, in the aggregate, at least 50% of the voting power of the stock outstanding and entitled to vote generally in the election of directors, any such newly created directorships or vacancies shall, unless otherwise provided by law, be filled solely by the affirmative vote of holders of a majority of the voting power of the stock outstanding and entitled to vote thereon. Any director so chosen shall hold office until the next election of directors of the class for which such director shall have been chosen, as applicable, and until his successor shall have been elected and qualified. No decrease in the authorized number of directors shall shorten the term of any incumbent director.

(c) Except for such additional directors, if any, as are elected by the holders of any series of Preferred Stock as provided for or fixed pursuant to the provisions of Article IV hereof (including any Preferred Stock Designation), and unless otherwise restricted by law, (i) prior to the date on which the Lone Star Entities cease to beneficially own, in the aggregate, a majority of the voting power of the stock outstanding and entitled

to vote generally in the election of directors, any director, or the entire Board of Directors, may be removed from office, with or without cause upon the affirmative vote of holders of a majority of the voting power of the stock outstanding and entitled to vote thereon, and (ii) on and after the date on which the Lone Star Entities cease to beneficially own, in the aggregate, a majority of the voting power of the stock outstanding and entitled to vote generally in the election of directors, any director, or the entire Board of Directors, may be removed from office, only for cause and only upon the affirmative vote of at least 66 ²⁄₃% of the voting power of the stock outstanding and entitled to vote thereon.

(d) During any period when the holders of any series of Preferred Stock have the right to elect additional directors as provided for or fixed pursuant to the provisions of Article IV hereof (including any Preferred Stock Designation), and upon commencement and for the duration of the period during which such right continues: (i) the then otherwise total authorized number of directors of the Corporation shall automatically be increased by such number of directors that the holders of any series of Preferred Stock have a right to elect, and the holders of such Preferred Stock shall be entitled to elect the additional directors so provided for or fixed pursuant to said provisions and (ii) each Preferred Stock Director shall serve until such Preferred Stock Director’s successor shall have been duly elected and qualified, or until such director’s right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to his or her earlier death, disqualification, resignation or removal. In case any vacancy shall occur among the Preferred Stock Directors, a successor may be elected by the holders of Preferred Stock pursuant to said provisions. Except as otherwise provided for or fixed pursuant to the provisions of Article IV hereof (including any Preferred Stock Designation), whenever the holders of any series of Preferred Stock having such right to elect additional directors are divested of such right pursuant to said provisions, the terms of office of all such Preferred Stock Directors elected by the holders of such Preferred Stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional directors, shall forthwith terminate and the total authorized number of directors of the Corporation shall be reduced accordingly.

Section 5.3 Powers. Subject to the provisions of the DGCL and to any limitations in this Certificate of Incorporation relating to action required to be approved by the stockholders, the business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors.

Section 5.4 Election; Annual Meeting of Stockholders.

(a) Ballot Not Required. The directors of the Corporation need not be elected by written ballot unless the Bylaws of the Corporation so provide.

(b) Notice. Advance notice of nominations for the election of directors, and of business other than a nomination, to be proposed by stockholders for consideration at a meeting of stockholders of the Corporation shall be given in the manner and to the extent provided in the Bylaws of the Corporation.

(c) Annual Meeting. The annual meeting of stockholders, for the election of directors to succeed those whose terms expire, if applicable, and for the transaction of such other business as may properly come before the meeting, shall be held at such place, if any, either within or without the State of Delaware, on such date, and at such time as the Board of Directors shall fix.

ARTICLE VI

Prior to the date on which the Lone Star Entities cease to beneficially own, in the aggregate, a majority of the voting power of the stock outstanding and entitled to vote generally in the election of directors, except as otherwise provided for or fixed pursuant to the provisions of Article IV hereof (including any Preferred Stock Designation), any action required or permitted to be taken at any annual or special meeting of the stockholders of the Corporation may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, are signed by the holders of the outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. References in this Article VI to written consent shall be deemed to include a telegram, cablegram or other electronic transmission consenting to an action to be taken if such transmission complies with Section 228(d) of the DGCL.
