ARTICLE V

INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 1. RIGHT TO INDEMNIFICATION AND ADVANCEMENT. Each person who was or is made a party or is threatened to be made a party to or is otherwise involved (including involvement, without limitation, as a witness) in any actual or threatened 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,

7

employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, 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 or officer or in any other capacity while serving as a director or officer, shall be indemnified and held harmless by the corporation to the fullest extent authorized by the General Corporation Law of the State of Delaware (the “DGCL”), as the same exists or may hereafter be amended (but, in the case of any 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 attorneys’ fees and related disbursements, judgments, fines, excise taxes, penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith and such indemnification shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the indemnitee’s heirs, executors and administrators; provided, however, that, except as provided in this Section 1 of this Article V with respect to proceedings to enforce rights to indemnification, the corporation shall indemnify any such 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 of Directors of the corporation. The right to indemnification conferred in this Section 1 of this Article V shall be a contract right. In addition to the right to indemnification conferred herein, an indemnitee shall also have the right to be paid by the corporation the expenses incurred in defending any such proceeding in advance of its final disposition (an “advance of expenses”); provided, however, that if and to the extent that the DGCL requires, an advance of expenses incurred by an indemnitee in his or her capacity as a director or officer (and not in any capacity in which service was or is rendered by such indemnitee, including without limitation, service to an employee benefit plan) shall be made only upon delivery to the corporation of an undertaking (an “undertaking”), by or on behalf of such 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 such indemnitee is not entitled to be indemnified for such expenses under this Section 1 or otherwise. The corporation may also, by action of its Board of Directors, provide indemnification and advancement to employees and agents of the corporation.

Section 2. PROCEDURE FOR INDEMNIFICATION. Any indemnification of a director or officer of the corporation or advance of expenses (including attorneys’ fees, costs and charges) under this Section 2 of this Article V shall be made promptly, and in any event within forty-five (45) days (or, in the case of an advance of expenses, twenty days, provided that the director or officer has delivered the undertaking contemplated by Section 1 of this Article V if required), upon the written request of the director or officer. If the corporation denies a written request for indemnification or advance of expenses, in whole or in part, or if payment in full pursuant to such request is not made within forty-five (45) days (or, in the case of an advance of expenses, twenty days, provided that the director or officer has delivered the undertaking contemplated by Section 1 of this Article V if required), the right to indemnification or advances as granted by this Article V shall be enforceable by the director or officer in any court of competent jurisdiction. Such person’s costs and expenses incurred in connection with successfully establishing his or her right to indemnification, in whole or in part, in any such action shall also be indemnified by the corporation. It shall be a defense to any such action (other than an action brought to enforce a claim for the advance of expenses where the undertaking required pursuant to Section 1 of this Article V, if any, has been tendered to the corporation) that the claimant has not met the standards of conduct which make it permissible under the DGCL for the corporation

8

to indemnify the claimant for the amount claimed, but the burden of such defense shall be on the corporation to the fullest extent permitted by law. Neither the failure of the corporation (including its Board of Directors, independent legal counsel or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the corporation (including its Board of Directors, independent legal counsel or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

Section 3. INSURANCE. The corporation may purchase and maintain insurance on its own behalf and on behalf of any person who is or was or has agreed to become a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify such person against such expenses, liability or loss under the DGCL.

Section 4. SERVICE FOR SUBSIDIARIES. Any person serving as a director, officer, employee or agent of another corporation, partnership, limited liability company, joint venture or other enterprise, at least 50% of whose equity interests are owned by the corporation (a “subsidiary” for this Article V) shall be conclusively presumed to be serving in such capacity at the request of the corporation.

Section 5. RELIANCE. Persons who after the date of the adoption of this provision become or remain directors or officers of the corporation or who, while a director or officer of the corporation, become or remain a director, officer, employee or agent of a subsidiary, shall be conclusively presumed to have relied on the rights to indemnity, advance of expenses and other rights contained in this Article V in entering into or continuing such service. The rights to indemnification and to the advance of expenses conferred in this Article V shall apply to claims made against an indemnitee arising out of acts or omissions which occurred or occur both prior and subsequent to the adoption hereof. Any amendment, alteration or repeal of this Article V that adversely affects any right of an indemnitee or its successors shall be prospective only and shall not limit, eliminate, or impair 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 or repeal.

Section 6. NON-EXCLUSIVITY OF RIGHTS. The rights to indemnification and to the advance of expenses conferred in this Article V shall not be exclusive of any other right which any person may have or hereafter acquire under the Certificate of Incorporation, the certificate of designation relating to any outstanding class or series of preferred stock or under any statute, by-law, agreement, vote of stockholders or disinterested directors or otherwise.

9

Section 7. SAVINGS CLAUSE. If this Article V or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the corporation shall nevertheless indemnify and advance expenses to each person entitled to indemnification under Section 1 as to all expense, liability and loss (including attorneys’ fees and related disbursements, judgments, fines, excise taxes, penalties and amounts paid or to be paid in settlement) actually and reasonably incurred or suffered by such person and for which indemnification and advancement of expenses is available to such person pursuant to this Article V to the fullest extent permitted by any applicable portion of this Article V that shall not have been invalidated and to the fullest extent permitted by applicable law.

Section 8. CORPORATION DEFINED; EFFECTS OF MERGER OR CONSOLIDATION. For the purposes of this Article V, 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 or officers so that any person who is or was a director or officer of such constituent corporation, or is or was serving at the request of such constituent corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Article V with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued.

Section 9. OTHER ENTERPRISES DEFINED. For purposes of this section, references to “other enterprises” shall include, without limitation, employee benefit plans; references to “fines” shall include, without limitation, any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the corporation” shall include, without limitation, 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.

CERTIFICATES OF STOCK

Section 1. CERTIFICATES. At the option of the Board of Directors, the stock of the corporation may be (i) uncertificated, evidenced by entries into the corporation’s stock ledger or other appropriate corporate books and records, as the Board of Directors may determine from time to time, or (ii) evidenced by a certificate signed by, or in the name of the corporation by, the Chairman or Vice-Chairman of the Board of Directors, or the President or a Vice President, and by the Secretary or an Assistant Secretary, or the Chief Financial Officer or an Assistant Treasurer of the corporation, certifying the number of shares represented by the certificate owned by such stockholder in the corporation.

Section 2. SIGNATURES ON CERTIFICATES. Any or all of the signatures on the certificate may be a facsimile. In case any officer, transfer agent, or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent, or registrar before such certificate is issued, it may be issued by the corporation with the same effect as if he were such officer, transfer agent, or registrar at the date of issue.

10

Section 3. LOST CERTIFICATES. The Board of Directors may direct a new certificate or certificates to be issued in place of any certificate or certificates theretofore issued by the corporation alleged to have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming the certificate of stock to be lost, stolen or destroyed. When authorizing such issue of a new certificate or certificates, the Board of Directors may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate or certificates, or his legal representative, to advertise the same in such manner as it shall require and/or to give the corporation a bond in such sum as it may direct as indemnity against any claim that may be made against the corporation with respect to the certificate alleged to have been lost, stolen or destroyed.

Section 4. TRANSFERS OF STOCK. Upon surrender to the corporation, or the transfer agent of the corporation, of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignation or authority to transfer, it shall be the duty of the corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books.

Section 5. FIXED RECORD DATE. In order that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of the stockholders, or any adjournment thereof, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix a record date which shall not be more than sixty (60) nor less than ten (10) days before the date of such meeting, nor more than sixty (60) days prior to any other action. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting. In order that the corporation may determine the stockholders entitled to consent to corporate action in writing without a meeting, the Board of Directors may fix a record date which shall not be more than ten (10) days after the date upon which the resolution fixing the record date is adopted by the Board of Directors.

Section 6. REGISTERED STOCKHOLDERS. The corporation shall be entitled to treat the holder of record of any share or shares of stock as the holder in fact thereof and accordingly shall not be bound to recognize any equitable or other claim or interest in such share on the part of any other person, whether or not it shall have express or other notice thereof, save as expressly provided by the laws of the State of Delaware.
