Page 6 of 8 ARTICLE IV - INDEMNIFICATION Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (“Proceeding”), by reason of the fact that such person, or a person of 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, trust or other enterprise, including service with respect to an employee benefit plan, whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as a director, officer, employee or agent, shall be indemnified and held harmless by the Corporation to the fullest extent permitted by the DGCL, as the same exists or hereafter may be amended (but, in the case of any amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment) against all expenses, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith. Such right shall include the right to be paid by the Corporation expenses incurred in defending any such Proceeding in advance of its final disposition; provided, however, that the payment of such expenses incurred by a director or officer in such person’s capacity as a director or officer (and not in any other capacity in which service was or is rendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of such Proceeding, shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it should be determined ultimately that such director or officer is not entitled to be indemnified under this Section or otherwise. Right of Claimant to Bring Suit. If a claim under Section 1 of this Article IV is not paid in full by the Corporation within ninety (90) days after a written claim has been received by the Corporation, the claimant 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 claimant shall be entitled to be paid also the expense 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 standard of conduct which makes it permissible under the DGCL for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. 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 the claimant 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 had not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant had not met the applicable standard of conduct.

Page 7 of 8 Non-Exclusivity of Rights. The rights conferred on a person by Sections 1 and 2 of this Article IV shall not be exclusive of any other right which such person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, By-Laws, agreement, vote of stockholders or disinterested Directors or otherwise. Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any such Director, officer, employee or agent of the Corporation or another corporation, partnership, trust or other enterprise against any such expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL. ARTICLE V - STOCK Certificate of Stock. Each stockholder shall be entitled to a certificate signed by, or in the name of the Corporation by, the President or Vice President, and by the Secretary or the Treasurer certifying the number of shares owned by such stockholder. Any of or all the signatures on the certificate may be facsimile. Transfers of Stock. Transfers of stock shall be made only upon the transfer books of the Corporation kept at an office of the Corporation or by transfer agents designated to transfer shares of the stock of the Corporation. Except where a certificate is issued in accordance with Section 4 of this Article, an outstanding certificate for the number of shares involved shall be surrendered for cancellation before a new certificate is issued therefor. Record Date. 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 any meeting of stockholders, nor more than sixty (60) days prior to the time for the other action hereinafter described, as of which there shall be determined the stockholders who are entitled: to notice of or to vote at any meeting of stockholders or any adjournment thereof; to express consent to corporate action in writing without a meeting; to receive payment of any dividend or other distribution or allotment of any rights; or to exercise any rights with respect to any change, conversion or exchange of stock or with respect to any other lawful action. Lost, Stolen or Destroyed Certificates. In the event of the loss, theft or destruction of any certificate of stock, another may be issued in its place pursuant to such requirements as the Board of Directors may establish concerning proof of such loss, theft or destruction and concerning the giving of a satisfactory undertaking or bond or bonds of indemnity. Dividends.
