FIFTH: The following provisions are inserted for the management of the business and the conduct of the affairs of the Corporation, and for further definition, limitation and regulation of the powers of the Corporation and of its directors and stockholders:

(a) 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 the Board of Directors by applicable law, this Second Amended and Restated Certificate of Incorporation or the Amended and Restated By-Laws of the Corporation (as amended from time to time, the “By-Laws”), 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, subject to the provisions of the DGCL and this Second Amended and Restated Certificate of Incorporation.

(b) The number of directors of the Corporation shall be fixed from time to time exclusively by resolution of the Board of Directors.

(c) Each director shall be elected at each annual meeting of stockholders for a term expiring at the next succeeding annual meeting of stockholders and each director shall remain in office until his or her successor shall have been duly elected and qualified, or until his or her earlier death, resignation, retirement, disqualification or removal. If the number of directors is increased, any additional director elected to fill a newly created directorship shall hold office for a term expiring at the next annual meeting of stockholders. In no case will a decrease in the number of directors shorten the term of any incumbent director.

(d) Subject to the terms of any one or more classes or series of Preferred Stock then outstanding, any vacancy on the Board of Directors that results from (i) removal of a director, (ii) an increase in the number of directors or (iii) death, resignation, retirement, disqualification or any other cause, will be filled solely by the affirmative vote of a majority of the remaining directors then in office, even if less than a quorum remains, including by a sole remaining director. Any director elected to fill a vacancy resulting from an increase in the number of directors shall hold office for a term expiring at the next succeeding annual meeting of stockholders. Any director elected to fill a vacancy

not resulting from an increase in the number of directors shall have the same remaining term as that of his or her predecessor. The right of stockholders to fill vacancies on the Board of Directors is hereby specifically denied.

(e) Notwithstanding the foregoing, the election, term, removal and filling of vacancies with respect to directors, if any, elected separately by the holders of one or more classes or series of Preferred Stock shall not be governed by this Article FIFTH, but rather shall be as provided for in the resolutions adopted by the Board of Directors creating and establishing such class or series of Preferred Stock.

SIXTH: No director shall be personally liable to the Corporation or any of its stockholders for monetary damages for breach of any fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL. If the DGCL is amended hereafter to authorize the further elimination or limitation of the liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent authorized by the DGCL, as so amended. Any repeal or modification of this Article SIXTH shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification with respect to acts or omissions occurring prior to such repeal or modification.

SEVENTH: The Corporation shall indemnify any person that is or was a director or officer (and any person that is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) to the fullest extent authorized or permitted by law, as now or hereafter in effect, and such right to indemnification shall continue as to a person who has ceased to be a director or officer of the Corporation (or such other corporation, partnership, joint venture, trust or other enterprise) and shall inure to the benefit of his or her heirs, executors and personal and legal representatives; provided, however, that, except for proceedings to enforce rights to indemnification, the Corporation shall not be obligated to indemnify any director or officer (or his or her heirs, executors or personal or legal representatives) in connection with a proceeding (or part thereof) initiated by such person unless such proceeding (or part thereof) was authorized or consented to by the Board of Directors. The right to indemnification conferred by this Article SEVENTH shall include the right to be paid by the Corporation the expenses incurred in defending or otherwise participating in any proceeding in advance of its final disposition.

The Corporation may, to the extent authorized from time to time by the Board of Directors, provide rights to indemnification and to the advancement of expenses to employees and agents of the Corporation similar to those conferred in this Article SEVENTH.

The rights to indemnification and to the advance of expenses conferred in this Article SEVENTH shall not be exclusive of any other right which any person may have or hereafter acquire under this Second Amended and Restated Certificate of Incorporation, the By-Laws, any statute or other law, by agreement, vote of stockholders or approval of the directors of the Corporation or otherwise.

Any repeal or modification of this Article SEVENTH shall not adversely affect any rights to indemnification and to the advancement of expenses of a director or officer of the Corporation existing at the time of such repeal or modification with respect to any acts or omissions occurring prior to such repeal or modification.

EIGHTH: Meetings of stockholders may be held within or without the State of Delaware, as the By-Laws may provide. The books of the Corporation may be kept (subject to any provision contained in the

DGCL) outside the State of Delaware at such place or places as may be designated from time to time by the Board of Directors or in the By-Laws.

NINTH: Except as otherwise required by law, special meetings of the stockholders of the Corporation, for any purpose or purposes, may be called at any time only (i) by the Chairman of the Board of Directors, (ii) by the Chief Executive Officer (or, in the absence of a Chief Executive Officer, the President) of the Corporation or (iii) pursuant to a resolution duly adopted by a majority of the Board of Directors. Any power of the stockholders to call a special meeting of stockholders is hereby specifically denied.

Advance notice of stockholder nominations for the election of directors of the Corporation and of business to be brought by stockholders before any meeting of stockholders of the Corporation shall be given in the manner provided in the By-Laws. No business other than that stated in the notice of such meeting (or any amendment or supplement thereto), which notice, in the case of a special meeting called by a stockholder or stockholders, shall include all business requested by such stockholder or stockholders to be transacted at such meeting, shall be transacted at any special meeting.

TENTH: In furtherance and not in limitation of the powers conferred upon it by the laws of the State of Delaware, the Board of Directors shall have the power without the assent or vote of the stockholders to adopt, amend, alter or repeal the By-Laws. The affirmative vote of at least a majority of the Board of Directors shall be required to adopt, amend, alter or repeal the By-Laws. The By-Laws also may be adopted, amended, altered or repealed by the affirmative vote of the holders of a majority of the Voting Stock.

ELEVENTH: The Corporation reserves the right to amend, alter, change or repeal any provision contained in this Second Amended and Restated Certificate of Incorporation, in the manner now or hereafter prescribed in the DGCL, and all rights conferred upon stockholders herein are granted subject to such reservation.

TWELFTH: The Court of Chancery of the State of Delaware shall, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (a) any actual or purported derivative action or proceeding brought on behalf of the Corporation, (b) any action asserting a claim of breach of a fiduciary duty owed by any director or officer of the Corporation to the Corporation or the Corporation’s stockholders or creditors, (c) any action asserting a claim against the Corporation or any director or officer of the Corporation arising pursuant to any provision of the DGCL, this Second Amended and Restated Certificate of Incorporation or the By-Laws, or (d) any action asserting a claim against the Corporation or any director or officer of the Corporation governed by the internal affairs doctrine; provided, however, that, if and only if the Court of Chancery of the State of Delaware dismisses any such action for lack of subject matter jurisdiction, such action may be brought in another state court sitting in the State of Delaware. Any person or entity purchasing or otherwise acquiring any interest in the shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article TWELFTH.

THIRTEENTH: If any provision or provisions of this Second Amended and Restated Certificate of Incorporation shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever: (i) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Second Amended and Restated Certificate of Incorporation (including, without limitation, each portion of any paragraph of this Second Amended and Restated Certificate of Incorporation containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and (ii) to the fullest extent possible, the provisions of this Second Amended and Restated Certificate of Incorporation (including, without limitation, each such portion of any paragraph of this Second Amended and Restated

Certificate of Incorporation containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to permit the Corporation to protect its directors, officers, employees and agents from personal liability in respect of their good faith service to or for the benefit of the Corporation to the fullest extent authorized or permitted by law.
