(a) Shares of Preferred Stock may be issued in one or more series from time to time, with each such series to consist of such number of shares and to have such voting powers, full or limited, or no voting powers, and such designations, preferences and relative, participating, optional or other special rights, and the qualifications, limitations or restrictions thereof, as shall be stated in the resolution or resolutions providing for the issuance of such series adopted by the board of directors of the Corporation (the “Board”) and included in a certificate of designations (a “Preferred Stock Designation”) filed pursuant to the DGCL, and the Board is hereby expressly vested with the authority, to the full extent now or hereafter provided by law, to adopt any such resolution or resolutions. The authority of the Board with respect to each series of Preferred Stock shall include, but not be limited to, determination of the following:

(i) the number of shares constituting that series and the distinctive designation of that series;

(ii) the dividend rate or rates on the shares of that series, the terms and conditions upon which and the periods in respect of which dividends shall be payable, whether dividends shall be cumulative, and, if so, from which date or dates, and the relative rights of priority, if any, of payment of dividends on shares of that series;

(iii) whether that series shall have voting rights, in addition to the voting rights provided by law, and, if so, the terms of such voting rights;

(iv) whether that series shall have conversion privileges, and, if so, the terms and conditions of such conversion, including provision for adjustment of the conversion rate in such events as the Board shall determine;

(b) Subject to the rights of the holders of any series of Preferred Stock pursuant to the terms of this Certificate (including any Preferred Stock Designation), the number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the outstanding shares of Common Stock, irrespective of the provisions of Section 242(b)(2) of the DGCL.

(c) Each holder of shares of Common Stock, as such, shall be entitled to one vote for each share of Common Stock held of record by such holder on all matters on which stockholders generally are entitled to vote; provided, however, that except as otherwise required by law or this Certificate (including a Preferred Stock Designation), holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate (including any amendment to any Preferred Stock Designation) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Certificate (including any Preferred Stock Designation) or pursuant to the DGCL.

ARTICLE V

DIRECTORS

5.1 Election. Unless and except to the extent that the By-Laws shall so require, the election of directors need not be by written ballot.

ARTICLE VI

LIMITATION OF DIRECTOR LIABILITY;

INDEMNIFICATION AND ADVANCEMENT OF EXPENSES

6.1 Limitation of Director Liability. To the fullest extent that the DGCL or any other law of the State of Delaware as the same exists or is hereafter amended permits the limitation or elimination of the liability of directors, no person who is or was a director of the Corporation shall be personally liable to the Corporation or any of its stockholders for monetary damages for breach of fiduciary duty as a director. Any repeal or amendment of this Section 6.1 by the stockholders of the Corporation or by changes in law, or the adoption of any other provision of this Certificate inconsistent with this Section 6.1 will, unless otherwise required by law, be prospective only (except to the extent such amendment or change in law permits the Corporation to further limit or eliminate the liability of directors) and shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or amendment or adoption of such inconsistent provision with respect to acts or omissions occurring prior to such repeal or amendment or adoption of such inconsistent provision.

6.2 Indemnification and Advancement of Expenses.

(a) To the fullest extent permitted by applicable law, as the same exists or may hereafter be amended, the Corporation shall indemnify and hold harmless each person who is or was made a party or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”) by reason of the fact that he or she is or was a director, officer, employee or agent of the Corporation or, while a director, officer, employee or agent of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, other enterprise or nonprofit entity, including service with respect to an employee benefit plan (an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent, or in any other capacity while serving as a director, officer, employee or agent, against all expenses, liability and loss (including, without limitation, attorneys’ fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee in connection with such proceeding. The right to indemnification conferred by this Section 6.2 shall include the right to be paid by the Corporation the expenses incurred in defending or otherwise participating in any such proceeding in advance of its final disposition; provided, however, that, if the DGCL requires, an advancement of expenses shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of the indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal that the indemnitee is not entitled to be indemnified for the expenses under this Section 6.2 or otherwise. The rights to indemnification and advancement of expenses conferred by this Section 6.2 shall be contract rights and such rights shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators. Notwithstanding the foregoing provisions of this Section 6.2, except for

proceedings to enforce rights to indemnification and advancement of expenses, the Corporation shall indemnify and advance expenses to an indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board.

(b) The rights to indemnification and advancement of expenses conferred on any indemnitee by this Section 6.2 shall not be exclusive of any other rights that any indemnitee may have or hereafter acquire under law, this Certificate, the By-Laws, an agreement, vote of stockholders or disinterested directors, or otherwise.

(c) Any repeal or amendment of this Section 6.2 by the stockholders of the Corporation or by changes in law, or the adoption of any other provision of this Certificate inconsistent with this Section 6.2, shall, unless otherwise required by law, be prospective only (except to the extent such amendment or change in law permits the Corporation to provide broader indemnification rights on a retroactive basis than permitted prior thereto), and shall not in any way diminish or adversely affect any right or protection existing at the time of such repeal or amendment or adoption of such inconsistent provision in respect of any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision.

(d) This Section 6.2 shall not limit the right of the Corporation, to the extent and in the manner authorized or permitted by law, to indemnify and to advance expenses to persons other than indemnitees.

ARTICLE VII

BY-LAWS

In furtherance and not in limitation of the powers conferred upon it by law, the Board shall have the power to adopt, amend, alter or repeal the By-Laws of the Corporation. The By-Laws also may be adopted, amended, altered or repealed by the stockholders.
