(c) Written notice of the annual meeting stating the place, date, and hour of the meeting shall be given to each Stockholder entitled to vote at such meeting not less than ten days nor more than sixty days prior to the date of the meeting. A written waiver of any such notice signed by the person entitled thereto, whether before or after the time stated therein, shall be deemed equivalent to notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends the meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened.

(d) The officer who has charge of the stock ledger of the Corporation shall prepare and make, at least ten days before every meeting of Stockholders, a complete list of the Stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each Stockholder and the number of shares registered in the name of each Stockholder. Such list shall be open to the examination of any Stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified,

at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any Stockholder who is present. The stock ledger shall be the only evidence as to the Stockholders entitled to examine the stock ledger, the list required by this section or the books of the Corporation, or to vote in person or by proxy at any meeting of Stockholders.

SECTION 2. Special Meetings. (a) Special meetings of the Stockholders, for any purpose or purposes, unless otherwise prescribed by statute or by the certificate of incorporation of the Corporation, may be called by the Board of Directors or by the Stockholders holding together at least a majority of all shares of the Corporation entitled to vote at the meeting.

Special meetings may be held at such place as shall be designated by the Board of Directors. Whenever the directors shall fail to fix such place, the meeting shall be held at the principal executive offices of the Corporation.

(c) Business transacted at any special meeting of Stockholders, other than procedural matters and matters relating to the conduct of the meeting, shall be limited to the purpose or purposes stated in the notice.

SECTION 3. Quorums.

Unless these By-Laws otherwise require, when a meeting is adjourned to another time or place, whether or not a quorum is present, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting, the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than thirty days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each Stockholder of record entitled to vote at the meeting. When a quorum is once present it is not broken by the subsequent withdrawal of any Stockholder.

(b) When a quorum is present at any meeting, the vote of the holders of a majority of the stock having voting power present in person or represented by proxy shall decide any question brought before such meeting, unless the question is one on which, by

express provision of Delaware Law or of the Certificate of Incorporation, a different vote is required, in which case such express provision shall govern and control the decision of such question.

SECTION 4. Organization. Meetings of Stockholders shall be presided over by the Chairman, if any, or if none or in the Chairman’s absence, the President, if any, or if none or in the President’s absence, by a Chairman to be chosen by the Stockholders entitled to vote who are present in person or by proxy at the meeting. The Secretary of the Corporation, or in the Secretary’s absence an Assistant Secretary, shall act as Secretary of every meeting and keep the minutes thereof, but if neither the Secretary nor an Assistant Secretary is present, the presiding officer of the meeting shall appoint any person present to act as secretary of the meeting. The order of business at all meetings of stockholders shall be as determined by the Chairman of the meeting.

SECTION 5. Voting; Proxies; Required Vote. (a) At each meeting of Stockholders, every Stockholder shall be entitled to vote in person or by proxy appointed by an instrument in writing, subscribed by such Stockholder or by such Stockholder’s duly authorized attorney-in-fact (but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period) and, unless Delaware Law or the Certificate of Incorporation provides otherwise, shall have one vote for each share of stock entitled to vote registered in the name of such Stockholder on the books of the Corporation on the applicable record date fixed pursuant to these By-Laws. At all elections of directors the voting may but need not be by ballot and a plurality of the votes cast there shall elect directors. Except as otherwise required by law or the Certificate of Incorporation, any other action shall be authorized by a majority of the votes cast.

(b) Where a separate vote by a class or classes, a majority of the outstanding shares of such class or classes, present in person or represented by proxy, shall constitute a quorum entitled to vote on that matter, the affirmative vote of the majority of shares of such class or classes present in person or represented by proxy at the meeting shall be the act of such class, unless otherwise provided in the Certificate of Incorporation.

SECTION 6. Inspector of Election. The Board of Directors, in advance of any meeting, may, but need not, appoint one or more inspectors of election to act at the meeting or any adjournment thereof. If an inspector or inspectors are not so appointed, the person presiding at the meeting may, but need not, appoint one or more inspectors. In case any person who may be appointed as an inspector fails to appear or act, the vacancy may be filled by appointment made by the directors in advance of the meeting or at the meeting by the person presiding thereat. Each inspector, if any, before entering upon the discharge of his or her duties, shall take and sign an oath faithfully to execute the duties of inspector at such meeting with strict impartiality and according to the best of his ability. The inspectors, if any, shall determine the number of shares of stock outstanding

3

and the voting power of each, the shares of stock represented at the meeting, the existence of a quorum, and the validity and effect of proxies, and shall receive votes, ballots or consents, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes, ballots or consents, determine the result, and do such acts as are proper to conduct the election or vote with fairness to all Stockholders. On request of the person presiding at the meeting, the inspector or inspectors, if any, shall make a report in writing of any challenge, question or matter determined by such inspector or inspectors and execute a certificate of any fact found by such inspector or inspectors.

SECTION 7. Action by Written Consent. Any action required or permitted to be taken at any meeting of the Stockholders may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock of the Corporation having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be filed with the minutes of proceedings of the Stockholders.

SECTION 1. Right to Indemnification. Each person who was or is 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 (a) that he or she is or was a director or officer of the Corporation, or (b) that he or she, being at the time a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, member, employee, fiduciary or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (collectively, “another enterprise” or “other enterprise”), shall be indemnified and held harmless by the Corporation to the fullest extent permitted by Delaware Law as the same exists or may hereafter be amended (but, in the case of any such amendment, with respect to alleged action or inaction occurring prior to such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than permitted prior thereto, against all expense, liability and loss (including, without limitation, attorneys’ and other professionals’ fees and expenses, claims, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) actually and reasonably incurred or suffered by such person in connection therewith (“Losses”). Without diminishing the scope of indemnification provided by this Section 1, such persons shall also be entitled to the further rights set forth below.

SECTION 2. Actions, Suits Or Proceedings Other Than Those By Or In The Right Of The Corporation. Subject to the terms and conditions of this Article, the Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any Proceeding (other than an action by or in the right of the Corporation) by reason of the fact that such person is or was a director or officer of the Corporation, or, being at the time a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, member, employee, fiduciary or agent of another enterprise, against all Losses, actually and reasonably incurred or suffered by such person in connection with such Proceeding if such person acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the conduct was unlawful. The termination of any Proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the conduct was unlawful.

SECTION 3. Actions, Suits Or Proceedings By Or In The Right Of The Corporation. Subject to the terms and conditions of this Article, the Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any Proceeding by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that such person is or was a director or officer of the Corporation, or being at the time a director or officer of the Corporation, is or was serving at the request

14

of the Corporation as a director, officer, member, employee, fiduciary or agent of another enterprise against all Losses actually and reasonably incurred or suffered by such person in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the Corporation except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

SECTION 4. Authorization of Indemnification. Any indemnification under this Article (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of a person is proper in the circumstances because such person has met the applicable standard of conduct required by Section 1 or set forth in Section 2 or 3 of this Article, as the case may be. Such determination shall be made in a reasonably prompt manner (i) by the Board of Directors by a majority vote of directors who were not parties to such action, suit or proceeding, whether or not they constitute a quorum of the Board of Directors, (ii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, (iii) by the stockholders or (iv) as Delaware Law may otherwise permit. To the extent, however, that a director or officer of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding described above, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ and other professionals’ fees) actually and reasonably incurred by such person in connection therewith, without the necessity of authorization in the specific case.

SECTION 5. Good Faith Defined. For purposes of any determination under Section 4 of this Article, a person shall be deemed to have acted in good faith if the action is based on (a) the records or books of account of the Corporation or another enterprise, or on information supplied to such person by the officers of the Corporation or another enterprise in the course of their duties or on (b) the advice of legal counsel for the Corporation or another enterprise, or on information or records given or reports made to the Corporation or another enterprise by an independent certified public accountant, independent financial adviser, appraiser or other expert selected with reasonable care by the Corporation or the other enterprise. The provisions of this Section 5 shall not be deemed to be exclusive or to limit in any way the circumstances in which a person may be deemed to have met the applicable standard of conduct.

SECTION 6. Proceedings Initiated by Indemnified Persons. Notwithstanding any provisions of this Article to the contrary, the Corporation shall not indemnify any person or make advance payments in respect of Losses to any person

15

pursuant to this Article in connection with any Proceeding (or portion thereof) initiated against the Corporation by such person unless such Proceeding (or portion thereof) is authorized by the Board of Directors or its designee; provided, however, that this prohibition shall not apply to a counterclaim, cross-claim or third-party claim brought in any Proceeding or to any claims provided for in Section 7 of this Article.

SECTION 7. Indemnification By A Court. Notwithstanding any contrary determination in the specific case under Section 4 of this Article, and notwithstanding the absence of any determination thereunder, any director or officer may apply to any court of competent jurisdiction for indemnification to the extent otherwise permissible under Section 1, 2 or 3 of this Article. Notice of any application for indemnification pursuant to this Section 7 shall be given to the Corporation promptly upon the filing of such application.

SECTION 8. Losses Payable In Advance. Losses reasonably incurred by an officer or director in defending any threatened or pending Proceeding may be paid by the Corporation in advance of the final disposition of such Proceeding if the Board of Directors determines that such advancement of expenses is appropriate and upon such terms and conditions, if any, as the Board of Directors deems appropriate.

SECTION 9. Non-exclusivity and Survival of Indemnification. The indemnification and advancement of expenses provided by or granted pursuant to this Article shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under the Certificate of Incorporation, any By-Law, agreement, contract, vote of Stockholders or of disinterested directors, or pursuant to the direction (howsoever embodied) of any court of competent jurisdiction or otherwise. The provisions of this Article shall not be deemed to preclude the indemnification of any person who is not specified in Section 1, 2 or 3 of this Article but whom the Corporation has the power or obligation to indemnify under the provisions of Delaware Law, or otherwise. The rights conferred 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 such person and the heirs, executors, administrators and other comparable legal representatives of such person. The rights conferred in this Article shall be enforceable as contract rights, and shall continue to exist after any rescission or restrictive modification hereof with respect to events occurring prior thereto. No rights are conferred in this Article for the benefit of any person (including, without limitation, officers or directors of subsidiaries of the Corporation) in any capacity other than as explicitly set forth herein.

SECTION 10. Meaning of certain terms in connection with Employee Benefit Plans, etc. For purposes of this Article, references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; references to “serving at the request of the Corporation” shall include any service as a director or officer of the Corporation which imposes duties on, or involves services by, such director or officer, with respect to an employee benefit plan, its participants or beneficiaries; and a

16

person who has acted in good faith and in a manner reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Corporation” as referred to in this Article.

SECTION 11. Insurance. The Corporation may, but shall not be required to, purchase and maintain insurance on behalf of any person who is or was a director, officer or employee of the Corporation, or is or was serving at the request of the Corporation as a director, officer, member, employee, fiduciary or agent of another against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the Corporation would have the power or the obligation to indemnify such person against such liability under the provisions of this Article.
