ARTICLE III

ARTICLE IV

SECTION 1. The total number of shares of all classes of stock which the Corporation shall have authority to issue is 2,200,000,000 shares of capital stock, consisting of (1) 1,200,000,000 shares of Preferred Stock, par value $0.001 per share (“Preferred Stock”), and (2) 1,000,000,000 shares of Common Stock, par value $0.001 per share (“Common Stock”). The number of authorized shares of either the Preferred Stock or the 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 in the combined voting power of the then outstanding shares of all classes and series of capital stock of the Corporation entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto), voting as a single class, and, unless otherwise provided in any certificate of designation setting forth the terms of a series of Preferred Stock, no vote of the holders of either the Preferred Stock or the Common Stock voting separately as a class shall be required therefor.

SECTION 2. (a) The Board of Directors of the Corporation (the “Board of Directors”) is hereby expressly authorized, by resolution or resolutions and without stockholder approval, to provide, out of the unissued shares of Preferred Stock, for series of Preferred Stock and, with respect to each such series, to fix the number of shares constituting such series and the designation of such series, the voting powers (if any) of the shares of such series, and the preferences and relative, participating, optional or other special rights, if any, and any qualifications, limitations or restrictions thereof, of the shares of such series. The powers, preferences and relative, participating, optional and other special rights of each series of Preferred Stock, and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other series at any time outstanding.

(b) For all purposes, this Second Amended and Restated Certificate of Incorporation shall be subject to and shall be deemed to include the terms and conditions of each certificate of designations (if any) setting forth the terms of a series of Preferred Stock (each, a “Certificate of Designations”), and all references to this Second Amended and Restated Certificate of Incorporation shall be deemed to include a reference to each such Certificate of Designations. In the event of a conflict between the terms of this Second Amended and Restated Certificate of Incorporation and any Certificate of Designations, the terms of the applicable Certificate of Designations shall be incorporated by reference and substituted for the inconsistent provision of the Second Amended and Restated Certificate so as to eliminate any inconsistency.

SECTION 3. (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 Second Amended and Restated Certificate of Incorporation 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 Second Amended and Restated Certificate of Incorporation, the DGCL, or a Certificate of Designations setting forth the terms of such series of Preferred Stock.

2

(b) Except as otherwise required by law, holders of a series of Preferred Stock, as such, shall be entitled only to such voting rights, if any, as shall expressly be granted to such holders by this Second Amended and Restated Certificate of Incorporation, including pursuant to any Certificate of Designations setting forth the terms of such series of Preferred Stock.

(c) Subject to applicable law and the rights, if any, of the holders of any outstanding series of Preferred Stock, dividends may be declared and paid on the Common Stock at such times and in such amounts as the Board of Directors in its discretion shall determine.

(d) Upon the dissolution, liquidation or winding up of the Corporation, subject to the rights, if any, of the holders of any outstanding series of Preferred Stock, the holders of the Common Stock, as such, shall be entitled to receive the assets of the Corporation available for distribution to its stockholders ratably in proportion to the number of shares held by them. For the avoidance of doubt, a dissolution, liquidation or winding up shall not be deemed to be occasioned by or to include, without limitation, any voluntary consolidation, reorganization, conversion or merger of the Corporation with or into any other corporation or entity or other corporation or entities or a sale, lease, transfer, exchange or conveyance of all or a part of the Corporation’s assets.

(e) Shares of Common Stock shall not entitle any holder thereof to any pre-emptive, subscription, redemption or conversion rights.

SECTION 4. The Corporation shall not issue nonvoting equity securities; provided, however, that the foregoing restriction shall (i) have no further force and effect beyond that required under Section 1123(a)(6) of Chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”), (ii) only have such force and effect for so long as Section 1123 of the Bankruptcy Code 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 may be in effect. The prohibition on the issuance of nonvoting equity securities is included in this Second Amended and Restated Certificate of Incorporation in compliance with Section 1123(a)(6) of the Bankruptcy Code; provided, that the foregoing shall not in any way restrict or prevent the issuance of any shares of Series B Preferred Stock (as defined in the Series A Investor Rights Agreement) regardless of any voting rights granted thereto.

ARTICLE V

SECTION 1. (a) The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. Except as otherwise fixed pursuant to the terms of any outstanding series of Preferred Stock pursuant to this Second Amended and Restated Certificate of Incorporation, the number of directors of the Corporation shall be fixed from time to time by the Board of Directors.

(b) The directors, other than those who may be elected by the holders of any series of Preferred Stock voting separately pursuant to this Second Amended and Restated Certificate of Incorporation, shall be elected by the stockholders entitled to vote thereon at each annual meeting of the stockholders.

The election of directors need not be by written ballot.

Any director elected in accordance with the first sentence of this Section 2 shall hold office for a term that shall coincide with the remaining term of such director and until such director’s successor shall have been duly elected and qualified or until his or her earlier resignation or removal.
