INDEMNIFICATION OF OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS

SECTION 1. RIGHT TO INDEMNIFICATION. Each person who was or is a party or is threatened to be made a party to or is involved (as a party, witness, or otherwise), in any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative (hereinafter a “Proceeding”), by reason of the fact that he, or a person of whom he is the legal representative, is or was a director or officer 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, or other enterprise, including service with respect to employee benefit plans, whether the basis of the Proceeding is alleged action in an official capacity as a director or officer or in any other capacity while serving as a director or (hereafter an “Indemnitee”), shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the General Corporation Law, as the same exists or may hereafter be amended or interpreted (but, in the case of any such amendment or interpretation, only to the extent that such amendment or interpretation permits the Corporation to provide broader indemnification rights than were permitted prior thereto) against all expenses, liability, and loss (including attorneys’ fees, judgments, fines, Employee Retirement Income Security Act excise taxes or penalties and amounts paid or to be paid in settlement and any interest, assessments, or other charges imposed thereon, and any federal, state, local, or foreign taxes imposed on any Indemnitee as a result of the actual or deemed receipt of any payments under this Article) reasonably incurred or suffered by such person in

connection with investigating, defending, being a witness in, or participating in (including on appeal), or preparing for any of the foregoing in, any Proceeding (hereinafter “Losses”); provided, however, that except as to actions to enforce indemnification rights pursuant to Section 3 of this Article V, the Corporation shall indemnify any Indemnitee seeking indemnification 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. The right to indemnification conferred in this Article shall be a contract right.

SECTION 2. AUTHORITY TO ADVANCE EXPENSES. Expenses (including attorneys’ fees) incurred by an Indemnitee in defending a Proceeding shall be paid by the Corporation in advance of the final disposition of such Proceeding, provided, however, that if required by the General Corporation Law, as amended, such expenses shall be advanced only upon delivery to the Corporation of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the Corporation as authorized in this Article or otherwise. Expenses incurred by other employees or agents of the Corporation may be advanced upon such terms and conditions as the Board deems appropriate. Any obligation to reimburse the Corporation for expense advanced shall be unsecured and no interest shall be charged thereon.

SECTION 3. RIGHT OF CLAIMANT TO BRING SUIT. If a claim under Section 1 or 2 of this Article V is not paid in full by the Corporation (i) in the case of a claim under Section 1, within ninety (90) days after the later of (a) the date on which a written claim for indemnification has been received by the Corporation and (b) the final disposition of the Proceeding for which indemnification is sought and (ii) in the case of a claim under Section 2, within thirty (30) days after a written claim for advancement has been received by the Corporation, the Indemnitee may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the Indemnitee shall be entitled to be paid also the expense (including attorneys’ fees) of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending a Proceeding in advance of its final disposition where the required undertaking has been tendered to the Corporation) that the claimant has not met the standards of conduct that make it permissible under the General Corporation Law for the Corporation to indemnify the claimant for the amount claimed. The burden of proving such a defense shall be on the Corporation. Neither the failure of the Corporation (including its Board, 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 under the circumstances because he or she has met the applicable standard of conduct set forth in the General Corporation Law, nor an actual determination by the Corporation (including its Board, independent legal counsel, or its stockholders) that the claimant had not met such applicable standard of conduct, shall be a defense to the action or create a presumption that claimant has not met the applicable standard of conduct.

SECTION 4. PROVISIONS NONEXCLUSIVE. The rights conferred on any person by this Article shall not be exclusive of any other rights that such person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, agreement, vote of stockholders or disinterested directors, or otherwise, both as to action in an official capacity and as to action in another capacity while holding such office.

SECTION 5. AUTHORITY TO INSURE. The Corporation may purchase and maintain insurance to protect itself and any director, officer, employee or agent of the Corporation against any Losses, whether or not the Corporation would have the power to indemnify such person against such Losses under applicable law or the provisions of this Article.

SECTION 6. SURVIVAL OF RIGHTS. The rights provided by this Article shall continue as to a person who has ceased to be an Indemnitee and shall inure to the benefit of the heirs, executors, and administrators of such a person.

SECTION 7. SETTLEMENT OF CLAIMS. The Corporation shall not be liable to indemnify any Indemnitee under this Article (i) for any amounts paid in settlement of any action or claim effected without the Corporation’s written consent, which consent shall not be unreasonably withheld; or (ii) for any judicial award if the Corporation was not given a reasonable and timely opportunity, at its expense, to participate in the defense of such action.

SECTION 8. EFFECT OF AMENDMENT. Any amendment, repeal, or modification of this Article shall not adversely affect any right or protection of any Indemnitee existing at the time of such amendment, repeal, or modification.

SECTION 9. SUBROGATION. In the event of payment under this Article, the Corporation shall be subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee, who shall execute all papers required and shall do everything that may be necessary to secure such rights, including the execution of such documents necessary to enable the Corporation effectively to bring suit to enforce such rights.

SECTION 10. NO DUPLICATION OF PAYMENTS. The Corporation shall not be liable under this Article to make any payment in connection with any claim made against the Indemnitee to the extent the Indemnitee has otherwise actually received payment (under any insurance policy, agreement, vote, or otherwise) of the amounts otherwise indemnifiable hereunder.

If no record date is fixed by the Board, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. 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 may fix a new record date for determination of stockholders entitled to vote at the adjourned meeting, and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance herewith at the adjourned meeting.

(ii) In order that the Corporation may determine the stockholders 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 may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall not be more than sixty days prior to such action. If no such record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board adopts the resolution relating thereto.

(iii) Unless otherwise restricted by the Certificate of Incorporation, in order that the Corporation may determine the stockholders entitled to express consent to corporate action without a meeting, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which

record date shall not be more than ten days after the date upon which the resolution fixing the record date is adopted by the Board. If no record date for determining stockholders entitled to express consent to corporate action without a meeting is fixed by the Board, (a) when no prior action of the Board is required by law, the record date for such purpose shall be the first date on which a signed consent setting forth the action taken or proposed to be taken is delivered to the corporation in accordance with applicable law, and (b) if prior action by the Board is required by law, the record date for such purpose shall be at the close of business on the day on which the Board adopts the resolution taking such prior action.

SECTION 4. DIVIDENDS. Subject to the provisions of the Certificate of Incorporation, the Board may, out of funds legally available therefor, declare dividends upon the capital stock of the Corporation as and when they deem expedient. Before declaring any dividend, there may be set apart out of any funds of the Corporation available for dividends such sum or sums as the Board from time to time in their discretion deem proper for working capital or as a reserve fund to meet contingencies or for equalizing dividends or for such other purposes as the Board shall deem conducive to the interests of the Corporation.

SECTION 5. SEAL. The corporate seal of the Corporation, if any, shall be circular in form and shall contain the name of the Corporation, the year of its creation and the words “CORPORATE SEAL DELAWARE”.

SECTION 8. NOTICE AND WAIVER OF NOTICE.

(i) Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the corporation under any provision of the General Corporation Law, the Certificate of Incorporation or these Bylaws may be given in writing directed to the stockholder’s mailing address (or by electronic transmission directed to the stockholder’s electronic mail address, as applicable) as it appears on the records of the Corporation. Notice shall be given (a) if mailed, when deposited in the United States mail, postage prepaid, (b) if delivered by courier service, the earlier of when the notice is received or left at the stockholder’s address, or (c) if given by electronic mail, when directed to such stockholder’s electronic mail address (unless the stockholder has notified the corporation in writing or by electronic transmission of an objection to receiving notice by electronic mail or such notice is prohibited by the General Corporation Law to be given by electronic transmission). A notice by electronic mail must include a prominent legend that the communication is an important notice regarding the Corporation. A notice by electronic mail will include any files attached thereto and any information hyperlinked to a website if such electronic mail includes the contact

information of an officer or agent of the Corporation who is available to assist with accessing such files or information. Any notice to stockholders given by the Corporation under any provision of the General Corporation Law, the Certificate of Incorporation or these bylaws provided by means of electronic transmission (other than any such notice given by electronic mail) may only be given in a form consented to by such stockholder, and any such notice by such means of electronic transmission shall be deemed to be given as provided by the General Corporation Law. The terms “electronic mail,” “electronic mail address,” “electronic signature” and “electronic transmission” as used herein shall have the meanings ascribed thereto in the General Corporation Law.

(ii) Except as otherwise provided herein or permitted by applicable law, notices to any director may be in writing and delivered personally or mailed to such director at such director’s address appearing on the books of the Corporation, or may be given by telephone or by any means of electronic transmission (including electronic mail) directed to an address for receipt by such director of electronic transmissions appearing on the books of the Corporation.

(iii) Whenever any notice whatsoever is required to be given under the provisions of any law or under the provisions of the Certificate of Incorporation or these Bylaws, a waiver thereof in writing or by electronic transmission given by the person or persons entitled to said notice, whether before or after the time stated therein, shall be deemed equivalent thereto.
