Article IX ---------- A director of the Corporation shall not be liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the General Corporation Law of Delaware as the same exists or may hereafter be amended. If the General Corporation Law of Delaware is amended after the date of the filing of this Certificate of Incorporation to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the General Corporation Law of Delaware as so amended. Any repeal or modification of this Article by the stockholders of the Corporation shall not adversely affect any right or protection of a director of the Corporation existing at the time, or increase the liability of any director of the Corporation with respect to any acts or omissions of such director occurring prior to, such repeal or modification. Article X --------- The Corporation may indemnify to the fullest extent permitted by law any person made or threatened to be made a party to an action or proceeding, whether criminal, civil, administrative or investigative, by reason of the fact that such person, his or her testator or intestate is or was a director, officer or employee of the Corporation or any predecessor of the Corporation or serves or served at any other enterprise as a director, officer or employee at the request of the Corporation or any predecessor to the Corporation. No repeal or modification of this Article by the stockholders shall adversely affect any right or protection of a director of the Corporation existing by virtue of this Article at the time of such repeal or modification. Article XI ---------- Except as otherwise provided for or fixed pursuant to the provisions of Article IV of this Certificate of Incorporation or any resolution or resolutions of the Board of Directors providing the issuance of any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation to elect additional directors under specified circumstances, the number of directors shall be determined by the Board of Directors in accordance with the Bylaws. The directors, other than those who may be elected by the holders of Preferred Stock or any other class or series of stock having a preference over the Common Stock as to dividends or upon liquidation pursuant to the terms of this Certificate of Incorporation or any resolution or resolutions providing for the issuance of such class or series of stock adopted by the Board of Directors, shall be divided into three classes, Class I, Class II and Class III, as nearly equal in number as possible. The term of office for the Class I directors shall expire at the annual meeting of the stockholders in 2001; the term of office for the Class II directors shall expire at the annual meeting of the stockholders in 2002; and the term of office for the Class III directors shall expire at the annual meeting of the stockholders in 2003. At each annual meeting of the stockholders commencing in 2001, the successors to the directors whose terms are expiring shall be elected to a term expiring at the third succeeding annual meeting of the stockholders. 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 directors of any class elected to fill a vacancy resulting from an increase in such class shall hold office for a term that shall coincide with 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. Article XII ----------- The Corporation hereby reserves the right at any time and from time to time to amend, alter, change, or repeal any provisions contained in this Certificate of Incorporation, and 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 any other persons whomsoever by or pursuant to this Certificate of Incorporation in its present form or as hereafter amended are granted subject to the right reserved in this Article.
