In furtherance and not in limitation of the powers conferred by statute and except as provided herein, the Board shall have the power to adopt, amend, repeal or otherwise alter the bylaws of the Corporation (the “Bylaws”) without any action on the part of the stockholders; provided, however, that any Bylaws made by the Board may be amended, altered or repealed by the stockholders. The Bylaws may only be amended, altered or repealed by the stockholders at an annual or special meeting of the stockholders the notice for which designates that an amendment, alteration or repeal of one or more of such sections is to be considered and then only by an affirmative vote of a majority in interest of the stockholders entitled to vote upon such amendment or repeal, voting as a single class.

Article VI

Indemnification of Directors

1. Limitation of Liability. No current or former director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except, to the extent provided by applicable law, for liability (i) for breach of the director’s duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the DGCL or (iv) for any transaction from which the director derived an improper personal benefit. If the DGCL is hereafter amended to authorize corporate action further limiting or eliminating the personal liability of directors, then the liability of each current or former director of the Corporation shall be limited or eliminated to the fullest extent permitted by the DGCL as so amended from time to time. Neither any amendment nor repeal of this Article VI, nor the adoption of any provision of this Certificate of Incorporation inconsistent with this Article VI, shall eliminate or reduce the effect of this Article VI in respect of any matter occurring, or any cause of action, suit or claim that, but for this Article VI, would accrue or arise, prior to such amendment, repeal or adoption of an inconsistent provision.

2. Indemnification. The Corporation shall, in accordance with this Certificate of Incorporation and the Bylaws, indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), any person who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”), by reason of the fact that he or she or a person for whom he or she is the legal representative, is or was a director of the Corporation or is or was serving at the request of the

- 4 -

Corporation as a director, officer, employee, member, trustee, partner, representative or agent of another corporation, partnership, limited liability company, joint venture, trust, enterprise or nonprofit entity, including service with respect to employee benefit plans maintained or sponsored by the Corporation (an “indemnitee”), against all expense, liability and loss (including attorneys’ fees, judgments, fines, excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee. The Corporation shall be required to indemnify an indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if the initiation of such proceeding (or part thereof) by the indemnitee was authorized by the Board. Each person who was, is or becomes a director shall be deemed to have served or to have continued to serve in such capacity in reliance upon the indemnity provided for in this Article VI. All rights to indemnification under this Article VI shall be deemed to have vested at the time such person becomes or became a director of the Corporation, and such rights shall continue as to an indemnitee who has ceased to be a director and shall inure to the benefit of the indemnitee’s heirs, executors and administrators. Any amendment, modification, alteration or repeal of this Article VI that in any way diminishes, limits, restricts, adversely affects or eliminates any right of an indemnitee or his or her successors to indemnification, advancement of expenses or otherwise shall be prospective only and shall not in any way diminish, limit, restrict, adversely affect or eliminate any such right with respect to any actual or alleged state of facts, occurrence, action or omission then or previously existing, or any action, suit or proceeding previously or thereafter brought or threatened based in whole or in part upon any such actual or alleged state of facts, occurrence, action or omission. Claims for indemnification shall be made pursuant to the procedural requirements of the Corporation’s Bylaws.

3. The Corporation may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

Article VII

Directors

1. Board of Directors. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. In addition to the powers and authority expressly conferred upon them by statute or by this Certificate of Incorporation or the Bylaws of the Corporation, the directors are hereby empowered to exercise all such powers and do all such acts and things as may be exercised or done by the Corporation.

2. Number, Term and Classes of Directors. The exact number of directors shall be fixed from time to time by resolution of the Board in accordance with the Bylaws. The Board (other than directors elected by the holders of any series or class of Preferred Stock provided for or fixed pursuant to the provisions of Article IV hereof) shall be divided into three classes designated Class I, Class II and Class III. The number of directors elected to each class shall be as nearly equal in number as possible. Directors shall be assigned to each class in accordance with a resolution or resolutions adopted by the Board. Each Class I director shall be

- 5 -

elected to an initial term to expire at the 2010 annual meeting of stockholders, each Class II director shall be elected to an initial term to expire at the 2011 annual meeting of stockholders; and each Class III director shall be elected to an initial term to expire at the 2012 annual meeting of stockholders. Upon the expiration of the initial terms of office for each class of directors, the directors of each class shall be elected for a term of three years to serve until their successors are duly elected and qualified or until their earlier resignation, death or removal from office. No decrease in the number of directors constituting the Board shall shorten the term of any incumbent director. Unless and except to the extent that the Bylaws shall so require, the election of directors of the Corporation need not be by written ballot.

3. Director Vacancies. Any director may resign at any time upon written notice to the Corporation. At a special meeting of stockholders called expressly for that purpose, the entire Board, or any member or members thereof, may be removed, but only for cause, by vote for removal of a specific director by stockholders holding at least 66  ²/3% of the voting power of the stockholders entitled to vote at an election for directors of the Corporation, voting as a single class. The notice of such special meeting must state that the purpose, or one of the purposes, of the meeting is removal of the director or directors, as the case may be. Any newly created directorship or any vacancy occurring in the Board for any cause may be filled by a majority of the remaining members of the Board, although such majority is less than a quorum, or by the sole remaining director. 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 or her successor is elected and qualified.

Article VIII

Except as otherwise required by law, a special meeting of stockholders (a “Special Meeting”) for any purpose or purposes may be called at any time only by the Chairman of the Board or the Board, to be held at such place, date and time as shall be designated in the notice or waiver of notice thereof. Only business within the purposes described in the Corporation’s notice of meeting required by the Bylaws may be conducted at the Special Meeting. The ability of the stockholders to call a Special Meeting is specifically denied. No action shall be taken by the stockholders except at an annual or Special Meeting called in accordance with this Certificate of Incorporation and the Bylaws, and no action shall be taken by the stockholders by written consent without a meeting.
