These Bylaws contain provisions for the regulation and management of the affairs of the Corporation.

In using these Bylaws, reference should also be made to the then current provisions of the laws of Delaware, the DGCL and the Certificate.

Directors need not be stockholders of the Corporation or residents of the state of incorporation. The number of directors may be increased or decreased by resolution of the Board from time to time. Directors shall hold office until the next succeeding annual meeting of stockholders or until their earlier resignation or removal or until their successors have been elected and qualified; however, no provision of this section shall be restrictive upon the right of the Board to fill vacancies or upon the right of stockholders to remove directors as is hereinafter provided.

A regular meeting of the Board for the purpose of electing officers and the transaction of such other business as may come before the meeting shall be held at the same place as, and immediately after, the annual meeting of stockholders, and no notice shall be required in connection therewith.

Section 3. Special Meetings of Board of Directors. Special meetings of the Board may be called at any time by the Chairman, the President (or in such person’s absence, by an Executive Vice President, a Senior Vice President or a Vice President), or a majority of the directors in office, on such notice as shall be reasonable under the circumstance and may be held within or outside the state of incorporation. Presence of any director at a meeting shall constitute waiver of notice of such meeting, except as otherwise provided by law. Unless specifically required by law, the Certificate, or the Bylaws, neither the business to be transacted at, nor the purpose of, any meeting of the Board need be specified in the notice or waiver of notice of such meeting.

Section 4. Quorum. A quorum at all meetings of the Board shall consist of a majority of the number of directors then fixed by the Bylaws or by action of the Board, but a smaller number may adjourn from time to time without further notice, until a quorum be secured. The act of the majority of the directors present at a meeting at which a quorum is present shall be the act of the Board, unless the act of a greater number is required by the Certificate, the Bylaws, or Law.

Section 5. Vacancies. Any vacancy occurring in the Board may be filled by the affirmative vote of a majority of the remaining directors though less than a quorum of the Board. A director elected to fill a vacancy shall be elected for the unexpired term of such person’s predecessor in office, and shall hold such office until such person’s earlier resignation or removal or until such person’s successor has been elected and qualified. Any directorship to be filled by reason of an increase in the number of directors shall be filled by the affirmative vote of the directors then in office or by an election at an annual meeting or at a special meeting of stockholders called for that purpose. A director chosen to fill a position resulting from an increase in the number of directors shall hold office until the next annual meeting of stockholders or until such person’s successor has been elected and qualified.

Section 6. Compensation of Directors. Directors may receive such fees as may be established by appropriate resolution of the Board for attendance at meetings of the Board, and in addition thereto, may receive reasonable traveling expense, if any is required, for attendance at such meetings.

In the absence or disqualification of a member of the Committee, the member or members present at any meeting and not disqualified from voting, whether or not such person(s) constitute(s) a quorum, may unanimously appoint another member of the Board to act at the meeting in the place of any such absent or disqualified member. The Committee shall have and may exercise to the fullest extent permitted by the Law, all the powers and authority of the Board in the management of the business and affairs of the Corporation, may act by and execute written consents, and may authorize the seal of the Corporation to be affixed to all papers which may require it.

Section 8. Removal of Directors. Any director or the entire Board may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors, except as follows: (1) Unless the Certificate otherwise provides, in the case of a corporation whose Board is classified, stockholders may effect such removal only for cause; or, (2) in the case of a corporation having cumulative voting, if less than the entire Board is to be removed, no director may be removed without cause if the votes cast against such person’s

removal would be sufficient to elect such person if then cumulatively voted at an election of the entire Board, or, if there be classes of directors, at an election of the class of directors which such person is a part.

Section 9. Meetings by Telephone. Members of the Board may participate in and act at any meeting of the Board through the use of a conference telephone or other communications equipment by means of which all persons participating in the meeting can hear each other. Participation in such a meeting shall constitute attendance and presence in person at the meeting of the person(s) so participating.

Section 10. Action Without a Meeting. Any action which is required to be taken at a meeting of the directors, or of any committee of the directors, may be taken without a meeting and without prior notice if all of the members of the board or of the committee as the case may be consent thereto in writing or by electronic transmission. The consents shall be filed in the corporate records. Action taken is effective when all directors or committee members have given the consent, unless the consent specifies a different effective date. Such consent has the same force and effect as an unanimous vote of the directors or committee members and may be stated as such in any document.

INDEMNIFICATION

Section 1. General. The Corporation shall indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended from time to time, 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 such person, or a person for whom such person is the legal representative, is or was a director or officer of the Corporation or 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, nonprofit entity or other enterprise, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including attorneys’ fees) judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with the proceeding. However, the Corporation shall be required to indemnify a person in connection with a proceeding (or part thereof) initiated by such person only if the proceeding (or part thereof) was authorized by the Board of the Corporation.

Section 2. Advances For Expenses. The Corporation shall pay the reasonable expenses (including attorneys’ fees) incurred by a director or officer of the Corporation in defending any proceeding in advance of its final disposition, provided, however, that the payment of expenses incurred by a director or officer in advance of the final disposition of the proceeding shall be made only upon a receipt of an undertaking by the director or officer to repay all expenses (including attorneys’ fees) advanced if it should be ultimately determined that the director or officer is not entitled to be indemnified under this Article or otherwise. Payment of such expenses incurred by other employees and agents of the Corporation may be made by the Board in its discretion upon such terms and conditions, if any, as it deems appropriate.

Section 3. Rights Not Exclusive. The rights conferred on any person by this Article shall not be exclusive of any other rights which such person may have or hereafter acquire under any statute, provision of the Certificate, these Bylaws, agreement, vote of stockholders or disinterested directors or otherwise. The indemnification and advancement of expenses provided for by this Article shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person.

Section 4. Claims. Notwithstanding any other provision of this Article, if a claim for indemnification or advancement of expenses under this Article is not paid in full within sixty days after a written claim therefor has been received by the Corporation, the claimant may file suit to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim. In any such action the Corporation shall have the burden of proving that the claimant was not entitled to the requested indemnification or advancement of expenses under applicable law.

Section 5. Other Indemnification. In the event of any payment under this Article, the Corporation shall be subrogated to the extent of such payment to all of the rights of recovery of the recipient of the payment, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Corporation to bring suit to enforce such rights. The Corporation shall not be liable to make any payment of amounts otherwise indemnifiable or subject to advancement hereunder if and to the extent that a person has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. To the extent that the Corporation maintains an insurance policy or policies providing liability insurance for directors, officers, employees, or agents of the

Corporation or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise which such person serves at the request of the Corporation, such person shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee or agent under such policy or policies. The Corporation’s obligation to indemnify or advance expenses hereunder to a person who is or was serving at the request of the Corporation as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount such person has actually received as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise.

Section 6. Amendment Or Repeal. Any repeal or modification of the foregoing provisions of this Article shall not adversely affect any right or protection hereunder of any person in respect of any act or omission occurring prior to the time of such repeal or modification.
