Article 5

INDEMNIFICATION

Section 5.1. Indemnification. The Corporation shall indemnify any director or officer of the Corporation and any director or officer of its subsidiaries against expenses, including legal fees, judgments, fines and amounts paid in settlement, actually and reasonably incurred by him to the fullest extent now or hereafter permitted by law in connection with any threatened, pending or completed action, suit, investigation or proceeding, whether derivative or nonderivative, and whether civil, criminal, administrative or investigative, brought or threatened to be brought against him by reason of his performance or status as a director or officer of the Corporation, any of its subsidiaries or any other entity in which he was serving at the request of the Corporation or in any other capacity on behalf of the Corporation, its parent or any of its subsidiaries if such officer or director acted in good faith and in a manner he 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 his conduct was unlawful.

Notwithstanding the foregoing, in the case of any threatened, pending or completed action or suit by or in the right of the Corporation, no indemnification shall be made in respect of any claim, issue or matter as to which such officer or director shall have been adjudged to be liable to the Corporation unless and only to the extent 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 shall deem proper.

The Board of Directors by resolution adopted in each specific instance may similarly indemnify any person other than a director or officer of the Corporation for liabilities

-15-

incurred by him in connection with services rendered by him for or at the request of the Corporation or any of its subsidiaries.

The provisions of this Section 5.1 shall be applicable to all actions, suits, investigations or proceedings commenced after its adoption, whether such arise out of acts or omissions which occurred prior or subsequent to such adoption and shall continue as to a person who has ceased to be a director or officer or to render services for or at the request of the Corporation and shall inure to the benefit of the heirs, executors and administrators of such a person. The rights of indemnification provided for herein shall not be deemed the exclusive rights to which any such director, officer or other person may be entitled.

Section 5.2. Authorization and Determination of Indemnification. Any indemnification under this Article 5, unless ordered by a court, shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director, officer or other person is proper in the circumstances because he has met the applicable standard of conduct as specified in Section 5.1 of this Article 5. A person shall be deemed to have met such applicable standard of conduct if his action is based in good faith on the records or books of account of the Corporation or another enterprise, or on information supplied to him by the officers of the Corporation or another enterprise in the course of their duties, or on 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 or by an appraiser or other expert selected with reasonable care by the Corporation or another enterprise.

Such determination shall be made (i) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (ii) if such a quorum is not obtainable, or, even if obtainable, a majority vote of a quorum of disinterested directors so directs, by independent legal counsel in a written opinion or (iii) by the stockholders. To the extent, however, that a director, officer or other person 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, he shall be indemnified against expenses, including attorneys’ fees, actually and reasonably incurred by him in connection therewith, without the necessity of authorization in the specific case.

The provisions of this Section 5.2 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 such applicable standard of conduct.

Section 5.3. Advances. Expenses incurred in defending or investigating a threatened or pending action, suit or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the director, officer or other person to repay such amount if it shall ultimately be

-16-

determined that he is not entitled to be indemnified by the Corporation as authorized in this Article 5.

Section 5.4. Scope and Alteration of Indemnification Provisions. The indemnification and advancement of expenses provided by, or granted pursuant to, the other sections of this Article 5 shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any By-law, agreement, contract, vote of the stockholders or disinterested directors or pursuant to the direction, howsoever embodied, of any court of competent jurisdiction or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, it being the policy of the Corporation that indemnification of, and advancement of expenses to, the persons specified in Section 5.1 of this Article 5 shall be made to the fullest extent permitted by the DGCL.

To this end, the provisions of this Article 5 shall be deemed to have been amended for the benefit of such persons effective immediately upon any modification of the DGCL which expands or enlarges the power or obligation of corporations organized under such law to indemnify, or advance expenses to, such persons. The provisions of this Article 5 shall not be deemed to preclude the indemnification of, or advancement of expenses to, any person who is not specified in this Section 5.4 or Section 5.1 of this Article 5 but whom the Corporation has the power or obligation to indemnify, or to advance expenses for, under the provisions of the DGCL.

Section 5.5. Insurance. The Corporation may 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 or employee of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the Corporation would have the power or the obligation to indemnify him against such liability under the provisions of this Article 5.

Section 5.6. Definitions. For purposes of this Article 5, references to the “Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer or employee of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer or employee of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Article 5 with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued.

-17-

The term “another enterprise” as used in this Article 5 shall mean any other corporation or any partnership, joint venture, trust or other entity of which such person is or was serving at the request of the Corporation as a director, officer, employee or agent and shall include employee benefit plans.

Section 5.7. Nature of Rights to Indemnification. The rights of indemnification conferred upon directors and officers of the Corporation in this Article 5 shall be contract rights. Any amendment, alteration or repeal of this Article 5 that adversely affects any right of a person indemnified under this Article 5 shall be prospective only and shall not limit or eliminate any such right with respect to any proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment, alteration or repeal.

Article 6

CAPITAL STOCK

Section 6.1. Certificated or Uncertificated Shares.

(a) Shares of any or all of the Corporation’s classes or series of capital stock may be evidenced by certificates for shares of stock, in such form as the Board of Directors may from time to time prescribe, or may be issued in uncertificated form. The issuance of shares in uncertificated form shall not affect shares already represented by a certificate until the certificate is surrendered to the Corporation. Except as expressly provided by law, there shall be no differences in the rights and obligations of stockholders based on whether or not their shares are represented by certificates. The Corporation shall issue to any holder who so requests share certificates representing shares registered in the holder’s name.

(b) Each certificate for shares of the Corporation’s capital stock shall be numbered and registered in a share register as it is issued, shall bear the name of the registered holder, the number and class of shares represented thereby and the par value of each share represented by the certificate or a statement that such shares are without par value, as the case may be, shall be signed by the President or any Vice President of the Corporation and the Secretary, any Assistant Secretary or the Treasurer of the Corporation or any other person properly authorized by the Board of Directors and shall bear the seal of the Corporation, which seal may be a facsimile engraved or printed. Where the certificate is signed by a transfer agent or a registrar, the signature of any corporate officer on such certificate may be a facsimile engraved or printed. In case any officer who has signed, or whose facsimile signature has been placed on, any share certificate shall have ceased to be such officer because of death, resignation or otherwise before the certificate is issued, the certificate may nevertheless be issued by the Corporation with the same effect as if the officer had not ceased to be such at the date of its issue.

-18-

(c) Within a reasonable time after the issuance or transfer of uncertificated shares, the Corporation shall send to the registered owner thereof a written notice containing the information required to be set forth or stated on stock certificates pursuant to the DGCL or a statement that the Corporation will furnish without charge to each stockholder who so requests the powers, designations, preferences and relative participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights.

Section 6.2. Transfers. Transfers of shares of capital stock of the Corporation shall be made only on the stock record of the Corporation by the holder of record thereof or by his attorney thereunto authorized by the power of attorney duly executed and filed with the Secretary of the Corporation or the transfer agent thereof, and (i) in the case of certificated shares, only on surrender of the certificate or certificates representing such shares, properly endorsed or accompanied by a duly executed stock transfer power, or (ii) in the case of uncertificated shares, upon receipt of proper transfer instructions from the registered owner of such uncertificated shares, or from a duly authorized attorney or from an individual presenting proper evidence of succession, assignment or authority to transfer the shares. The Board of Directors may make such additional rules and regulations as it may deem expedient concerning the issue and transfer of certificates representing shares of capital stock of the Corporation.

Section 6.3. Lost Certificates. Should any stockholder of the Corporation allege the loss, theft or destruction of one or more certificates for shares of the Corporation and request the issuance by the Corporation of a substitute certificate or uncertificated shares therefor, the Board of Directors may direct that a new certificate of the same tenor and for the same number of shares or uncertificated shares be issued to such person upon such person’s making of an affidavit in form satisfactory to the Board of Directors setting forth the facts in connection therewith, provided that prior to the receipt of such request the Corporation shall not have either registered a transfer of such certificate or received notice that such certificate has been acquired by a bona fide purchaser. When authorizing such issuance of a new certificate or uncertificated shares, the Board of Directors may, in its discretion and as a condition precedent to the issuance of such certificate or uncertificated shares, require the owner of such lost, stolen or destroyed certificate, or his heirs or legal representatives, as the case may be, to advertise the same in such manner as the Board of Directors shall require and/or to give the Corporation a bond in such form and for such sum and with such surety or sureties, with fixed or open penalty, as shall be satisfactory to the Board of Directors, as indemnity for any liability or expense that it may incur by reason of the original certificate remaining outstanding.

Section 6.4. Dividends. The Board of Directors may, from time to time, at any duly convened regular or special meeting or by unanimous consent, declare and pay dividends

-19-

upon the outstanding shares of capital stock of the Corporation in cash, property or shares of the Corporation.

Before payment of any dividend, there may be set aside out of any funds of the Corporation available for dividends such sum or sums as the Board of Directors from time to time, in its absolute discretion, shall deem proper as a reserve fund to meet contingencies, or for equalizing dividends, or for repairing or maintaining any property of the Corporation or for such other purposes as the Board of Directors shall believe to be in the best interests of the Corporation, and the Board of Directors may reduce or abolish any such reserve in the manner in which it was created.

Such notice shall specify the place, day and hour of the meeting, if any, and, in the case of a special meeting of the stockholders, the general nature of the business to be transacted.

Section 11.2. Waiver of Notice. Any written notice required to be given to any person may be waived in a writing signed by the person entitled to such notice whether before or after the time stated therein. Attendance of any person entitled to notice, whether in person or by proxy, at any meeting shall constitute a waiver of notice of such meeting, except where any person attends a meeting for the express purpose of objecting to the transaction of any business because the meeting was not lawfully called or convened. Where written notice is required for any meeting, the waiver thereof must specify the purpose only if it is for a special meeting of the stockholders.

Section 11.3. Computing Time Periods. In computing the number of days for purposes of these By-laws, all days shall be counted, including Saturdays, Sundays or holidays; provided, however, that if the final day of any time period falls on a Saturday, Sunday or holiday, then the final day shall be deemed to be the next day which is not a Saturday, Sunday or holiday. In computing the number of days for the purpose of giving notice of any meeting, the date upon which the notice is given shall be counted but the day set for the meeting shall not be counted.
