STOCK

Section 4.1 Authorized Stock. The total number of shares which the Corporation shall have authority to issue is 1,900,000,000, of which 1,800,000,000 shall be designated as Common Stock, par value $.01 per share (the “Common Stock”), and 100,000,000 shall be designated as Preferred Stock, par value $.01 per share (the “Preferred Stock”). For the avoidance of doubt, notwithstanding anything herein to the contrary, pursuant to Section 1123(a)(6) of chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”), the Corporation shall not issue non-voting equity securities; provided, however, that the foregoing restriction (i) shall have no further force or effect beyond that required under Section 1123 of the Bankruptcy Code, (ii) shall have such force and effect, if any, only for so long as such section is in effect and applicable to the Corporation and (iii) in all events may be amended or eliminated in accordance with applicable law as from time to time in effect.

Section 4.2 Common Stock.

(a) Each holder of Common Stock, as such, shall be entitled to one vote for each share of Common Stock held of record by such holder on all matters on which stockholders

generally are entitled to vote; provided, however, that, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate of Incorporation, including any certificate of designations relating to any series of Preferred Stock (each hereinafter referred to as a “Preferred Stock 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 such series, to vote thereon pursuant to this Certificate of Incorporation (including any Preferred Stock Designation).

(b) Dividends. Subject to the rights of the holders of any outstanding series of Preferred Stock, the holders of shares of Common Stock shall be entitled to receive dividends out of any funds of the Corporation legally available therefor when, as and if declared by the Board of Directors, and shall share equally on a per share basis in all such dividends.

(c) Liquidation. Upon the dissolution, liquidation or winding up of the Corporation, subject to the rights of the holders of any outstanding series of Preferred Stock, the holders of shares of Common Stock shall be entitled to receive the assets of the Corporation available for distribution to its stockholders ratably in proportion to the number of shares of Common Stock held by them. A merger or consolidation of the Corporation with any other corporation or other entity, or a sale or conveyance of all or any part of the assets of the Corporation (which shall not in fact result in the liquidation of the Corporation and the distribution of assets to its stockholders) shall not be deemed to be a voluntary or involuntary dissolution, liquidation or winding up of the Corporation.

Section 4.3 Preferred Stock. The Preferred Stock may be issued from time to time in one or more series. Subject to limitations prescribed by law and the provisions of this Article IV, the Board of Directors is hereby authorized to provide by resolution and by causing the filing of a Preferred Stock Designation for the issuance of the shares of Preferred Stock in one or more series, and to establish from time to time the number of shares to be included in each such series, and to fix the designations, powers, preferences, and relative, participating, optional or other rights, if any, and the qualifications, limitations or restrictions, if any, of the shares of each such series.

The authority of the Board of Directors with respect to each series shall include, but not be limited to, determination of the following:

(i) the number of shares constituting such series, which number the Board of Directors may thereafter (except where otherwise provided in the Preferred Stock Designation) increase or decrease (but not below the number of shares in any such series then outstanding), and the distinctive designation of such series, which may be by distinguishing number, letter or title;

(ii) the dividend rate (or method of determining such rate) on the shares of such series, if any; whether dividends shall be cumulative, and, if so, from which date or dates, and the relative rights of priority, if any, of payment of dividends on shares of such series;

2

(iii) whether the shares of such series shall have voting rights (including multiple, fractional or no votes per share) in addition to the voting rights provided by law, and, if so, the terms of such voting rights;

(iv) whether the shares of such series shall have conversion rights, and, if so, the terms and conditions of such rights, including provision for adjustment of the conversion rate in such events as the Board of Directors shall determine;

(v) whether or not the shares of such series shall be redeemable, and if so, the terms and conditions of such redemption, including the date or dates upon or after which they shall be redeemable, and the amount per share payable in case of redemption, which amount may vary under different conditions and at different redemption rates;

(vi) whether a sinking fund shall be provided for the redemption or purchase of shares of such series, and, if so, the terms and the amount of such sinking fund;

(vii) the restrictions, if any, on the issuance of the same series or of any other class or series;

(viii) the rights of the shares of such series in the event of voluntary or involuntary liquidation, dissolution or winding up of the Corporation, and the relative rights of priority, if any, of payment of shares of such series; and

(ix) any other relative rights, powers, preferences and qualifications, limitations or restrictions of such series.

Unless otherwise provided in the resolution or resolutions providing for the issuance of such series of Preferred Stock, shares of Preferred Stock, regardless of series, which shall be issued and thereafter acquired by the Corporation through purchase, redemption, exchange, conversion or otherwise shall return to the status of authorized but unissued Preferred Stock, without designation as to series of Preferred Stock, and the Corporation shall have the right to reissue such shares.

Section 4.4 No Class Vote on Changes in Authorized Number of Shares of Stock. Subject to the rights of the holders of any outstanding series of Preferred Stock, the number of authorized shares of any class or classes of stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of at least a majority of the voting power of the stock entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL.

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 such number of directors as shall be determined from time to time solely by resolution adopted by the affirmative vote of a majority of the total number of directors then authorized.

3

Section 5.2 Classification.

(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, 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. In case of any increase or decrease, from time to time, 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. Any director so chosen shall hold office until the next election of the class for which such director shall have been chosen and until his or her successor shall have been duly elected and qualified, or until such director’s earlier death, resignation, disqualification or removal. A director may resign at any time upon notice to the Corporation as provided in the Corporation’s Bylaws. 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), any director, or the entire Board of Directors, may be removed from office at any time, but only for cause and only by the affirmative vote of at least a majority 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

4

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 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 nominations, 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 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
