            (b)  The Corporation may in its Bylaws confer powers upon the Board of Directors in addition to the foregoing and in addition to the powers and authorities expressly conferred upon the Board of Directors by law.

            (c)  Notwithstanding anything contained in this Second Amended and Restated Certificate of Incorporation to the contrary, the affirmative vote of at least sixty-six and two- thirds percent (66 2/3%) of the votes cast in such vote, provided that such affirmative vote represents at least a majority of the Voting Stock (as defined below), either present or represented by proxy, voting together as a single class, shall be required to amend, repeal or adopt any provision inconsistent with (i) Articles FOURTH, FIFTH, EIGHTH, NINTH, TENTH or ELEVENTH hereof or (ii) Section 2.2, 2.4, 2.5, 2.7 or 2.10 of Article II, Section 3.2, 3.3, 3.5, 3.7 or 3.10 of Article III, Section 4.3 of Article IV, Article V or Article X of the Bylaws of the Corporation. "Voting Stock" shall mean the outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors.

        SIXTH: (a) Subject to the rights of the holders of any series of Preferred Stock or any other series or class of stock as set forth in this Second Amended and Restated Certificate of Incorporation to elect additional directors under specified circumstances or to consent to specific actions taken by the Corporation, any action required or permitted to be taken by the stockholders of the Corporation must be effected at a duly called annual or special meeting of stockholders of the Corporation and may not be effected by any consent in writing in lieu of a meeting of such stockholders.

    stock of the Corporation entitled to vote on any business to be considered at any such meeting may be called by the Chairman of the Board of Directors, the Chief Executive Officer of the Corporation, or pursuant to a resolution adopted by a majority of the total number of directors which the Corporation would at the time have if there were no vacancies (the "Whole Board").

            (c)  Notwithstanding anything contained in this Second Amended and Restated Certificate of Incorporation to the contrary, the affirmative vote of at least sixty-six and two- thirds percent (66 2/3%) of the votes cast in such vote, provided that such affirmative vote represents at least a majority of the Voting Stock, either present or represented by proxy, voting together as a single class, shall be required to amend, repeal or adopt any provision inconsistent with this Article SIXTH.

        SEVENTH: (a) Subject to the rights of the holders of any series of Preferred Stock or any other series or class of stock as set forth in this Second Amended and Restated Certificate of Incorporation to elect additional directors under specified circumstances, the Board of Directors shall consist of not less than five (5) nor more than nine (9) members, the exact number of which shall be fixed from time to time by the affirmative vote of a majority of the Whole Board.

Each class shall consist, as nearly as may be possible, of such number of members as would constitute one-third of the Whole Board. The initial division of the members of the Board of Directors into classes shall be made by the affirmative vote of a majority of the Whole Board. Class I directors shall initially be elected for a term expiring at the 2005 annual meeting of stockholders, Class II directors shall initially be elected for a term expiring at the 2006 annual meeting of stockholders, and Class III directors shall initially be elected for a term expiring at the 2007 annual meeting of stockholders. Members of each class shall hold office until their resignation, removal or until their successors are elected and qualified. At each succeeding annual meeting of the stockholders of the Corporation, the successors of the class of directors whose term expires at that meeting shall be elected to hold office for a term expiring at the annual meeting of stockholders held in the third year following the year of their election, and until their resignation, removal or until their successors are elected and qualified.

            (d)  Subject to the rights of the holders of any series of Preferred Stock or any other series or class of stock as set forth in this Second Amended and Restated Certificate of Incorporation to elect additional directors under specified circumstances, any director may be removed from office at any time, but only for cause and only by the affirmative vote of the holders of at least sixty-six and two- thirds percent (66 2/3%) of the votes cast in such vote, provided that such affirmative vote represents at least a majority of the Voting Stock, either present or represented by proxy, voting together as a single class.

            (e)  Advance notice of stockholder nominations for the election of directors shall be given in the manner provided in the Bylaws of the Corporation.

            (f)  Subject to the rights of the holders of any series of Preferred Stock or any other series or class of stock as set forth in this Second Amended and Restated Certificate of Incorporation to elect additional directors under specified circumstances, vacancies resulting from death, resignation, retirement, disqualification, removal from office or other cause, and newly created directorships resulting from any increase in the authorized number of directors, may be filled only by the affirmative vote of a majority of the remaining directors, though less than a quorum of the

4



    Board of Directors, and directors so chosen shall hold office for a term expiring at the annual meeting of stockholders at which the term of office of the class to which they have been elected expires and until such director's successor shall have been duly elected and qualified. No decrease in the number of authorized directors constituting the Whole Board shall shorten the term of any incumbent director.

            (g)  Notwithstanding anything contained in this Second Amended and Restated Certificate of Incorporation to the contrary, the affirmative vote of at least sixty-six and two- thirds percent (66 2/3%) of the votes cast in such vote, provided that such affirmative vote represents at least a majority of the Voting Stock, either present or represented by proxy, voting together as a single class, shall be required to amend, repeal or adopt any provisions inconsistent with this Article SEVENTH.

No amendment or repeal of this Article EIGHTH shall adversely affect any right or protection of a director of the Corporation existing hereunder in respect of any act or omission occurring prior to such amendment or repeal.

        NINTH: (a) Any Fundamental Transaction (as defined below) entered into by the Corporation or any of its Subsidiaries (as defined below) with any other corporation, limited liability company, partnership, trust or other entity or any person shall require the affirmative vote of the holders of not less than sixty-six and two-thirds percent (66 2/3%) of the votes cast in such vote, provided that such affirmative vote represents at least a majority of the Voting Stock, either present or represented by proxy, voting together as a single class. For the purposes of this Second Amended and Restated Certificate of Incorporation, "Fundamental Transaction" shall mean (1) (A) any merger, consolidation or share exchange with or into any corporation, limited liability company, partnership, trust or other entity or any person, (B) any sale, lease, exchange, mortgage, pledge, transfer or other disposition of all or substantially all the property or assets of the Corporation, including stock or assets of any of its Subsidiaries, in a single transaction or series of related transactions, (C) any filing of a voluntary or consent to filing of an involuntary petition for relief under title 11 of the United States Code or any successor statute or under any reorganization, arrangement, insolvency, readjustment of debt, dissolution or liquidation law with respect to the Corporation of any of its material subsidiaries or (D) any dissolution or liquidation of the Corporation or revocation thereof; provided that, in each such case, the DGCL or the rules of any applicable national securities exchange or inter-dealer quotation system on which the Corporation's securities are listed or quoted, as applicable, requires that such transaction, or series of related transactions, be approved or authorized by a vote of holders of the Corporation's Common Stock.
