ARTICLE 3

QUORUM OF SHAREHOLDERS

Section 3.1. The presence, in person or by proxy, of shareholders entitled to cast at least a majority of the votes which all shareholders are entitled to cast on the particular matter shall constitute a quorum for purposes of considering such matter, and unless otherwise provided by statute the acts of such shareholders at a duly organized meeting shall be the acts of the shareholders. If, however, any meeting of shareholders cannot be organized because of lack of a quorum, those present, in person or by proxy, shall have the power, except as otherwise provided by statute, to adjourn the meeting to such time and place as they may determine, without notice other than an announcement at the meeting, until the requisite number of shareholders for a quorum shall be present, in person or by proxy, except that in the case of any meeting called for the election of directors such meeting may be adjourned only for periods not exceeding fifteen (15) days as the holders, present in person or by proxy, of shares entitled to cast at least a majority of the votes which all shareholders are entitled to cast, shall direct, and those who attend the second of such adjourned meetings, although less than a quorum, shall nevertheless constitute a quorum for the purpose of electing directors. At any adjourned meeting at which a quorum shall be present or so represented, any business may be transacted which might have been transacted at the original meeting if a quorum had been present. The shareholders present, in person or by proxy, at a duly organized meeting can continue to do business until adjournment, notwithstanding the withdrawal of enough shareholders to leave less than a quorum.

In such case, only such shareholders as shall be shareholders of record on the date so fixed shall be entitled to notice of, or to vote at, such meeting or to receive payment of such dividend or to receive such allotment of rights or to exercise such rights, as the case may be, notwithstanding any transfer of any shares on the books of the Corporation after any record date fixed as aforesaid. The Board of Directors may close the books of the Corporation against transfers of shares during the whole or any part of such period, and in such case written or printed notice thereof shall be mailed at least ten days before closing thereof to each shareholder of record at the address appearing on the records of the Corporation or supplied by him to the Corporation for the purpose of notice. While the stock transfer books of the Corporation are closed, no transfer of shares shall be made thereon. If no record date is fixed by the Board of Directors for the determination of shareholders entitled to receive notice of, and vote at, a shareholders’ meeting, transferees of shares which are transferred on the books of the Corporation within ten (10) days next preceding the date of such meeting shall not be entitled to notice of or to vote at such meeting.

The number of judges shall be one or three. If appointed at a meeting on the request of one or more shareholders or proxies, the holders of shares, present in person or by proxy, entitled to cast at least nine (9) votes which all shareholders are entitled to cast shall determine whether one (1) or three (3) judges are to be appointed. No person who is a candidate for office shall act as a judge. The judges of election shall do all such acts as may be proper to conduct the election or vote, and such other duties as may be prescribed by statute, with fairness to all shareholders, and if requested by the Chairman of the meeting or any shareholder or his proxy, shall make a written report of any matter determined by them and execute a certificate of any fact found by them. If there are three (3) judges of election, the decision, act or certificate of a majority shall be the decision, act or certificate of all.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 23.1 The Corporation shall indemnify, to the fullest extent permitted by Pennsylvania law and federal law, any director, officer and/or employee, or any former director, officer and/or employee, who was or is a party to, or is threatened to be made a party to, or who is called to be a witness in connection with, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (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, officer and /or employee 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 expenses (including attorney’s fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he 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. The termination of any action, suit or 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 which 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 reasonable cause to believe that his conduct was unlawful.

11

Section 23.2 The Corporation shall indemnify, to the fullest extent permitted by Pennsylvania law and federal law, any director, officer and/or employee, who was or is a party to, or is threatened by to be made a party to, or who is called as a witness in connection with any threatened, pending or completed action or suit 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, officer and/or employee or agent of another Corporation, partnership, joint venture, trust or other enterprise against amounts paid in settlement and expenses (including attorney’s fees) actually and reasonably incurred by him in connection with the defense or settlement of, or serving as a witness in, such action or suit if he 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 except that no indemnification shall be made in respect of any such claim, issue or matter as to which such person shall have been adjudged to be liable for misconduct in the performance of his duty to the Corporation.

Section 23.3 Except as may be otherwise ordered by a court, there shall be a presumption that any director, officer and/or employee is entitled to indemnification as provided in Sections 23.1 and 23.2 of this Article unless either a majority of the directors who are not involved in such proceedings (“disinterested directors”) or, if there are less than three (3) disinterested directors, then the holders of one-third of the outstanding shares of the Corporation determine that the person is not entitled to such presumption by certifying such determination in writing to the Secretary of the Corporation. In such event the disinterested director(s) or, in the event of certification by shareholders, the Secretary of the Corporation shall request of independent counsel, who may be the outside general counsel of the Corporation, a written opinion as to whether or not the parties involved are entitled to indemnification under Sections 23.1 and 23.2 of this Article.

Section 23.4 Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid by the Corporation in advance of the final disposition of such action, suit or proceeding as authorized in the manner provided under Section 23.3 of this Article upon receipt of an undertaking by or on behalf of the director, officer and/or employee to repay such amount unless it shall ultimately be determined that he is entitled to be indemnified by the Corporation as authorized in this Article.

Section 23.5 The indemnification provided by this Article shall not be deemed exclusive of any other rights to which a person seeking indemnification may be entitled under any agreement, vote of shareholders or disinterested directors, or otherwise, both as to action in his official capacity while serving as a director, officer and/or employee and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer and/or employee and shall inure to the benefit of the heirs and personal representatives of such a person.

ARTICLE 24

SHARE CERTIFICATES

Section 24.1. The share certificates of the Corporation shall be numbered and registered in a share register as they are issued, shall bear the name of the registered holder, the number and class of shares represented thereby, the par value of each share or a statement that such shares

12

are without par value, as the case may be, shall be signed by the President or a Vice President and the Secretary or the Treasurer or any other person properly authorized by the Board of Directors; and shall bear the corporate seal, 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 upon, any share certificate shall have ceased to be such officer because of death, resignation or otherwise before the certificate is issued, it may 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.

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 certificates. The rights and obligations of the holders of shares represented by certificates and the rights and obligations of the holders of uncertificated shares of the same class shall be identical. Notwithstanding anything herein to the contrary, the provisions of Section 24.1 shall not apply to uncertificated shares and, in lieu thereof, the Board of Directors shall adopt alternative procedures for registration of transfers.
