The business and affairs of the Corporation shall be managed by or under the direction of the Board. The number of directors shall, at the Effective Time, be the number of directors then in office and shall thereafter, subject to any limitations which may be set forth in the By-Laws and subject to the right, if any, of holders of shares of Preferred Stock outstanding to elect additional directors expressly set forth in the resolution or resolutions providing for the issuance of such shares, be such number or such greater or lesser number as may be fixed from time to time and at any time by a resolution or resolutions adopted by the affirmative vote of a majority of the Whole Board.

A director elected to fill such a vacancy shall hold office until the due election and qualification of his successor (which may be such director, if he is re-elected) at the annual meeting of stockholders next following his election or his earlier death, resignation or removal.

NINTH: BY-LAWS

The Amended and Restated By-Laws of the Corporation approved by the stockholders concurrently with approval by the stockholders of this Certificate of Incorporation shall, at the Effective Time, be the By-Laws.

After the Effective Time, all or any part of the By-Laws may be amended or repealed and new By-Laws may be adopted at any time and from time to time pursuant to (but only pursuant to) a resolution or resolutions adopted by the affirmative vote of a majority of the Whole Board, but subject to the power of the holders of shares of capital stock of the Corporation then outstanding to adopt, amend or repeal the By-Laws as provided in the next paragraph and to the limitations set forth in the By-Laws immediately after the Effective Time.

Subject to the next sentence, all or any part of the By-Laws may be amended or repealed and new By-Laws may be adopted by the stockholders upon (but only upon) the affirmative vote of holders of at least 67% of the voting power of all shares of capital stock of the Corporation then outstanding entitled to vote generally for the election of directors. The reference to 67% in the preceding sentence shall be deemed to refer to 50% if the Principal Stockholder (as defined below) votes in favor of such amendment, repeal or adoption. As used

herein, “Principal Stockholder” means the Nominating Stockholder who, together with its affiliates, holds at the Effective Time more than 50% of the outstanding shares of Common Stock; provided, however, that there shall be no “Principal Stockholder” after such time as such Nominating Stockholder, together with its affiliates, ceases to hold more than 20% of the outstanding shares of Common Stock.

TENTH: EXCULPATION

A director shall not be personally liable to the Corporation or the stockholders for monetary damages for breach of fiduciary duty as a director, except (i) for any breach of the duty of loyalty of such director to the Corporation or such holders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the Law and (iv) for any transaction from which such director derives an improper personal benefit. If the Law is hereafter amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director shall be eliminated or limited to the fullest extent permitted by the Law, as so amended. No repeal or modification of this Article TENTH shall adversely affect any right of or protection afforded to a director prior to such repeal or modification.

ELEVENTH: AMENDMENTS

Subject to the next sentence, notwithstanding any other provision contained in this Certificate of Incorporation and notwithstanding that a lesser percentage may be specified by law, the By-Laws or otherwise, Articles SEVENTH, EIGHTH, NINTH and TENTH of this Certificate of Incorporation and this Article ELEVENTH shall not be amended or repealed, and no provision inconsistent therewith or providing for cumulative voting in the election of directors shall be adopted, unless such adoption, amendment or repeal is approved by the affirmative vote of holders of at least 67% of the voting power of all shares of capital stock of the Corporation then outstanding entitled to vote generally for the election of directors. The reference to 67% in the preceding sentence shall be deemed to refer to 50% if the Principal Stockholder votes in favor of such amendment, repeal or adoption.

Subject to the immediately preceding paragraph of this Article ELEVENTH, the Corporation reserves the right to amend, alter, change or repeal any provision contained herein in the manner now or hereafter prescribed by law.

TWELFTH: COMPROMISE

Whenever a compromise or arrangement is proposed between the Corporation and its creditors or any class of them and/or between the Corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of the Corporation or of any creditor or stockholder thereof or on the application of any receiver or receivers appointed for the Corporation under the provisions of Section 291 of Title 8 of the Delaware Code or on the application of trustees in dissolution or of any receiver or receivers appointed for the Corporation under the provisions of Section 279 of Title 8 of the Delaware Code order a meeting of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, to be summoned in
