The Common Stock shall be subject to the express terms of the Preferred Stock and any series thereof. Except as may otherwise be provided in this Amended and Restated Certificate of Incorporation, in a Preferred Stock Designation or by applicable law, the holders of shares of Common Stock shall be entitled to one vote for each such share upon all questions presented to the shareholders and shall not have cumulative voting rights, the Common Stock shall have the exclusive right to vote for the election of directors and for all other purposes, and holders of Preferred Stock shall not be entitled to vote at or receive notice of any meeting of shareholders.

The Corporation shall be entitled to treat the person in whose name any share of its stock is registered as the owner thereof for all purposes and shall not be bound to recognize any equitable or other claim to, or interest in, such share on the part of any other person, whether or not the Corporation shall have notice thereof, except as expressly provided by applicable law.

FIFTH. Unless and except to the extent that the By-laws of the Corporation shall so require, the election of directors of the Corporation need not be by written ballot.

SIXTH.(1) The business and affairs of the Corporation shall be managed by, or under the direction of, the Board of Directors. The Board of Directors shall have that number of directors set out in the By-laws of the Corporation as adopted or as set from time to time by a duly adopted amendment thereto by the directors or shareholders of the Corporation.

(2) The Board of Directors (other than those directors elected by the holders of any series of Preferred Stock provided for or fixed pursuant to the provisions of Article FOURTH hereof (the “Preferred Stock Directors”)) shall be divided into three classes, as nearly equal in number as possible, designated Class I, Class II and Class III. Class I directors shall initially serve until the 2007 meeting of shareholders; Class II directors shall initially serve until the 2008 meeting of shareholders; and Class III directors shall initially serve until the 2009 meeting of shareholders. Commencing with the annual meeting of shareholders in 2007, directors of each class the term of which shall then expire shall be elected to hold office for a three-year term and until the election and qualification of their respective

successors in office. In case of any increase or decrease, from time to time, in the number of directors (other than Preferred Stock Directors), the number of directors in each class shall be apportioned as nearly equal as possible.

(3) Subject to the rights of the holders of any one or more series of Preferred Stock then outstanding, newly created directorships resulting from any increase in the authorized number of directors or any vacancies in the Board of Directors resulting from death, resignation, retirement, disqualification, removal from office or other cause shall be filled solely by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of the Board of Directors. Any director so chosen shall hold office until the next election of the class for which such director shall have been chosen and until his successor shall be elected and qualified. No decrease in the number of directors shall shorten the term of any incumbent director.

(4) Except for Preferred Stock Directors, if any, any director, or the entire Board of Directors, may be removed from office at any time, but only for cause and only by the affirmative vote of at least 75% of the total voting power of the outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors (the “Voting Stock”), voting together as a single class.

(5) During any period when the holders of any series of Preferred Stock have the right to elect additional directors as provided for or fixed pursuant to the provisions of Article FOURTH hereof, then upon commencement and for the duration of the period during which such right continues: (i) the then otherwise total authorized number of directors of the Corporation shall automatically be increased by such specified number of directors, and the holders of such Preferred Stock shall be entitled to elect the additional directors so provided for or fixed pursuant to said provisions and (ii) each such additional director shall serve until such director’s successor shall have been duly elected and qualified, or until such director’s right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to his earlier death, disqualification, resignation or removal. Except as otherwise provided by the Board of Directors in the resolution or resolutions establishing such series, whenever the holders of any series of Preferred Stock having such right to elect additional directors are divested of such right pursuant to the provisions of such stock, the terms of office of all such additional directors elected by the holders of such stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional directors, shall forthwith terminate and the total and authorized number of directors of the Corporation shall be reduced accordingly.

SEVENTH. In furtherance and not in limitation of the powers conferred by the laws of the State of Delaware, the Board of Directors is expressly authorized to make, alter and repeal the By-laws of the Corporation.

Notwithstanding any other provisions of the Certificate of Incorporation or the By-laws of the Corporation and in addition to any other vote required by law, the affirmative vote of the holders of not less than 75% of the Voting Stock, voting together as a single class, shall be required in order for shareholders to alter, amend or repeal any provision of the By-laws of the Corporation.

EIGHTH. A director of the Corporation shall not be liable to the Corporation or its shareholders 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 the State of Delaware as the same exists or may hereafter be amended. If the General Corporation Law of the State of Delaware is amended after the effective date of this Amended and Restated 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 the State of Delaware, as so amended.

Any amendment, modification or repeal of the foregoing paragraph shall not adversely affect any right or protection of a director of the Corporation hereunder with respect to any act or omission occurring prior to the time of such amendment, modification or repeal.

NINTH. Except as otherwise provided for or fixed pursuant to the provisions of Article FIFTH of this Amended and Restated Certificate of Incorporation relating to the rights of holders of any series of Preferred Stock, no action that is required or permitted to be taken by the shareholders of the Corporation at any annual or special meeting of shareholders may be effected by written consent of shareholders in lieu of a meeting of shareholders, unless the action to be effected by written consent of shareholders and the taking of such action by such written consent have expressly been approved in advance by the Board of Directors.

TENTH. 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 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 shareholders, directors or 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 rights reserved in this article.

ELEVENTH. The Corporation elects not to be governed by Section 203 of the General Corporation Law of the State of Delaware.

TWELFTH. Notwithstanding anything to the contrary elsewhere contained in this Amended and Restated Certificate of Incorporation of the Corporation, the affirmative vote of the holders of at least 75% of the Voting Stock, voting together as a single class, shall be required to alter, amend or repeal, or to adopt any provision inconsistent with, the following Articles of this Amended and Restated Certificate of Incorporation: Article FOURTH, Article SIXTH, Article SEVENTH, Article EIGHTH, Article NINTH and Article TWELFTH.
