(b) None of (i) any Original Stockholder or any of its Affiliates or (ii) any Non-Employee Director or his or her Affiliates (the Persons (as defined below) identified in (i) and (ii) above being referred to, collectively, as “Identified Persons” and, individually, as an “Identified Person”) shall have any duty to refrain from directly or indirectly (x) engaging in a corporate opportunity in the same or similar business activities or lines of business in which the Corporation or any of its Affiliates now engages or proposes to engage or (y) otherwise competing with the Corporation, and, to the fullest extent permitted by the DGCL, no Identified Person shall (A) be deemed to have acted in bad faith or in a manner inconsistent with the best interests of the Corporation or its stockholders or to have acted in a manner inconsistent with or opposed to any fiduciary duty to the Corporation or its stockholders or (B) be liable to the Corporation or its stockholders for breach of any fiduciary duty, in each case, by reason of the fact that such Identified Person engages in any such activities.

(c) The Corporation does not renounce its interest in any corporate opportunity offered to any Non-Employee Director (including any Non-Employee Director who serves as an officer of this Corporation) if such opportunity is expressly offered to such person solely in his or her capacity as a director or officer of the Corporation and the provisions of Section 5.2(b) shall not apply to any such corporate opportunity.

(d) In addition to and notwithstanding the foregoing provisions of this Section 5.2, a corporate opportunity shall not be deemed to be a potential corporate opportunity for the Corporation if it is a business opportunity that the Corporation is not financially able or contractually permitted or legally able to undertake, or that is, from its nature, not in the line of the Corporation’s business or is of no practical advantage to it or that is one in which the Corporation has no interest or reasonable expectancy.

Section 6.2 Number, Election and Term.

(a) The number of directors constituting the Board shall be not fewer than five (5) nor more than thirteen (13). Subject to the previous sentence, the precise number of directors of the Corporation, other than those who may be elected by the holders of one or more series of Preferred Stock voting separately by class or series, shall be fixed from time to time exclusively pursuant to a resolution adopted by a majority of the Whole Board. For purposes of this Certificate, “Whole Board” shall mean the total number of directors the Corporation would have if there were no vacancies.

Section 6.5 Preferred Stock – Directors. Notwithstanding any other provision of this Article VI, and except as otherwise required by law, whenever the holders of one or more series of Preferred Stock shall have the right, voting separately by class or series, to elect one or more directors, the term of office, the filling of vacancies, the removal from office and other features of such directorships shall be governed by the terms of such series of Preferred Stock as set forth in this Certificate (including any Preferred Stock Designation) and such directors shall not be included in any of the classes created pursuant to this Article VI unless expressly provided by such terms.

Section 8.2 Special Meetings. Except as otherwise required by law or the terms of any one or more series of Preferred Stock, special meetings of stockholders of the Corporation may be called only by the Chairman of the Board, Chief Executive Officer, or the Board pursuant to a resolution adopted by a majority of the Whole Board, and the ability of the stockholders to call a special meeting is hereby specifically denied.

LIMITATION OF DIRECTOR LIABILITY; INDEMNIFICATION AND

ADVANCEMENT OF EXPENSES

Section 9.1 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 9.1 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 9.1 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

6

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.

Section 9.2 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 or officer of the Corporation or, while a director or officer 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 9.2 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 9.2 or otherwise. The rights to indemnification and advancement of expenses conferred by this Section 9.2 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 9.2, 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 9.2 shall not be exclusive of any other rights that any indemnitee may have or hereafter acquire under law, this Certificate, the Bylaws, an agreement, vote of stockholders or disinterested directors, or otherwise.

(c) Any repeal or amendment of this Section 9.2 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 9.2, 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.

7

(d) This Section 9.2 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.
