Notwithstanding any other provision of this Amended and Restated Certificate of Incorporation or the By-Laws of the Corporation (and notwithstanding that a lesser percentage may be specified by law), the provisions of Article II, Sections 1, 2 and 5, Article III, Section 1, and Article VI of the By-Laws of the Corporation may not be amended or repealed, nor may any By-Law provision inconsistent therewith be adopted, by the stockholders of the Corporation, unless such action is approved by the affirmative vote of the holders of not less than sixty-six and two thirds percent (66 2/3%) of the voting power of all of the outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors, considered for purposes of this Article SEVENTH as a single class. EIGHTH: The Corporation reserves the right at any time and from time to time to amend, alter, change or repeal any provision contained in this Amended and Restated Certificate of Incorporation, and any other provisions authorized by the laws of the State of Delaware at the time in force may be added or inserted, in the manner now or hereafter prescribed by law; and all rights, preferences and privileges of whatsoever nature conferred upon stockholders, directors or 5 6 any other persons whomsoever by and pursuant to this Amended and Restated Certificate of Incorporation in its present form or as hereafter amended are granted subject to the right reserved in this Article EIGHTH. Notwithstanding any other provisions of this Amended and Restated Certificate of Incorporation or the By-Laws of the Corporation (and notwithstanding that a lesser percentage may be specified by law), the provisions of this Article EIGHTH, Article SEVENTH, Article NINTH, Article TENTH, Article ELEVENTH, Article TWELFTH, Article THIRTEENTH and Article FOURTEENTH hereof may not be amended or repealed, nor may any Certificate of Incorporation provision inconsistent therewith be adopted, by the stockholders of the Corporation unless such action is approved by the affirmative vote of the holders of not less than sixty-six and two thirds percent (66 2/3%) of the voting power of all of the outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors, considered for purposes of this Article EIGHTH as a single class. NINTH: (1) The business and affairs of the Corporation shall be managed by or under the direction of a Board consisting of not fewer that six (6) nor more than eleven (11) directors (exclusive of directors referred to in the following paragraph), the exact number to be determined from time to time by resolution adopted by affirmative vote of a majority of such directors then in office. Upon the filing of this Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, the directors shall be divided into three classes, designated Class I, Class II and Class III. Each class shall consist, as nearly as may be possible, of one-third of the total number of directors determined by the Board pursuant to this Section (1). Class I directors shall serve for an initial term ending at the annual meeting of 6 7 stockholders held in 2000, Class II directors for an initial term ending at the annual meeting of stockholders held in 2001 and Class III directors for an initial term ending at the annual meeting of stockholders held in 2002. At each annual meeting of stockholders beginning in 2000, successors to the directors in the class whose term expires at that annual meeting shall be elected for a three-year term. If the number of directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain the number of directors in each class as nearly equal as possible, and any additional director of any class elected to fill a vacancy resulting from an increase in such class shall hold office for the remaining term of that class, but in no case will a decrease in the number of directors shorten the term of any incumbent director. A director shall hold office until the annual meeting for the year in which his or her term expires and until his or her successor shall be elected and shall qualify, subject, however, to prior death, resignation, retirement, disqualification or removal from office. Notwithstanding the foregoing, whenever the holders of any one or more classes or series of Preferred Stock issued by the Corporation shall have the right, voting separately by class or series, to elect directors at an annual or special meeting of stockholders, the number of such directors and the election, term of office, filling of vacancies and other features of such directorships shall be governed by the provisions of Article FOURTH of this Amended and Restated Certificate of Incorporation and any resolution or resolutions adopted by the Board pursuant thereto, and such directors shall not be divided into classes unless expressly so provided therein. (2) Subject to the rights of the holders of any one or more classes or series of Preferred Stock issued by the Corporation, any director, or the entire Board, may be removed from office at any time, but only for cause and only by the affirmative vote of the holders of not less than sixty-six and two thirds percent (66 2/3%) of the voting power of all of the outstanding 7 8 shares of capital stock of the Corporation entitled to vote generally in the election of directors, considered for purposes of this sentence as a single class. Any vacancy in the Board that results from an increase in the number of directors may be filled by a majority of the directors then in office, provided that a quorum is present, and any other vacancy may be filled only by a majority of the directors then in office, even if less than a quorum, or by a sole remaining director. Any director elected to fill a vacancy not resulting from an increase in the number of directors shall hold office for the remaining term of his or her predecessor. TENTH: No action required to be taken or that may be taken at any annual or special meeting of stockholders of the Corporation may be taken by stockholders of the Corporation except at such a meeting of stockholders. ELEVENTH: The Corporation shall, to the full extent permitted by Section 145 of the Delaware General Corporation Law, as amended from time to time, indemnify all persons whom it may indemnify pursuant thereto. TWELFTH: The Board shall have authority to authorize the issuance, from time to time without any vote or other action by the stockholders, of any or all shares of stock of the Corporation of any class at any time authorized, any securities convertible into or exchangeable for any such shares so authorized, and any warrant, option or right to purchase, subscribe for or otherwise acquire shares of stock of the Corporation for any such consideration and on such terms as the Board from time to time in its discretion lawfully may determine, which terms and conditions may include, without limitation, restrictions or conditions that preclude or limit the exercise, transfer or receipt thereof or that invalidate or void any such securities, warrants, options or rights; provided, however, that the consideration for the issuance of shares of stock of the Corporation having par value shall not be less than such par value. Stock so issued, for 8 9 which the consideration has been paid to the Corporation, shall be fully paid stock, and the holders of such stock shall not be liable to any further call or assessments thereon. Nothing in this Article TWELFTH shall be interpreted to limit the authority of the Board under the Delaware General Corporation Law or under any other provision of this Amended and Restated Certificate of Incorporation, to authorize the issuance of shares, warrants, options or rights or other securities or to take any other action. THIRTEENTH: The By-Laws of the Corporation may establish procedures regulating the submission by stockholders of nominations and proposals for consideration at meetings of stockholders of the Corporation. FOURTEENTH: The provisions of Section 203 of the Delaware General Corporation Law shall not apply to or govern the Corporation. FIFTEENTH: 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 such manner as the said court directs. If a majority in number representing three-fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, agree 9 10 to any compromise or arrangement and to any reorganization of the Corporation as consequence of such compromise or arrangement, the said compromise or arrangement and the said reorganization shall, if sanctioned by the court to which the said application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of the Corporation, as the case may be, and also on the Corporation. SIXTEENTH: The personal liability of the directors of the Corporation is hereby eliminated to the fullest extent permitted by paragraph (7) of subsection (b) of Section 102 of the General Corporation Law of the State of Delaware, as the same may be amended or supplemented. 10
