Section 2. Election of Directors. Directors shall be elected at the annual meeting of shareholders, but when the annual meeting is not held or directors are not elected thereat, they may be elected at a special meeting called and held for that purpose.

Section 10. Notice of Annual or Special Meetings. Notice of the time and place of each annual or special meeting shall be given to each director by the secretary or by the person or persons calling such meeting. Such notice need not specify the purpose or purposes of the

meeting and may be given in any manner or method and at such time so that the director receiving it may have reasonable opportunity to participate in the meeting. Such notice shall, in all events, be deemed to have been properly and duly given if mailed at least forty-eight (48) hours prior to the meeting and directed to the residence of each director as shown upon the secretary’s records and, in the event of a meeting to be held through the use of communications equipment, if the notice sets forth the telephone number at which each director may be reached for purposes of participation in the meeting as shown upon the secretary’s records and states that the secretary must be notified if a director desires to be reached at a different telephone number.

The directors, as such, shall be entitled to receive such reasonable compensation for their services as may be fixed from time to time by resolution of the board, and expenses of attendance, if any, may be allowed for attendance at each annual, regular or special meeting of the board. Nothing herein contained shall be construed to preclude any director from serving the Corporation in any other capacity and receiving compensation therefor. Members of the executive committee or of any standing or special committee may by resolution of the board be allowed such compensation for their services as the board may deem reasonable, and additional compensation may be allowed to directors for special services rendered.

The Corporation shall indemnify any person who was or is a party or is threatened to be made a party, to 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 he is or was a director, officer, employee, or agent of the Corporation, or is or was serving at the request of the Corporation as a director, trustee, officer, employee, or agent of another corporation; domestic or foreign, nonprofit or for profit, partnership, joint venture, trust, or other enterprise, against expenses, including attorneys’ 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, he had reasonable cause to believe this his conduct was unlawful.

Section 2. Indemnification in Derivative Actions. The Corporation shall indemnify any person who was or is a party, or is threatened to be made a party to 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 he is or was a director, officer, employee, or agent of the Corporation, or is or was serving at the request of the Corporation as a director, trustee, officer, employee, or agent of another corporation, domestic or foreign, nonprofit or for profit, partnership, joint venture, trust, or other enterprise against expenses, including attorneys’ fees, actually and reasonably incurred by him in connection with the defense or settlement of 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, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be

liable for negligence or misconduct in the performance of his duty to the Corporation unless, and only to the extent that the Court of Common Pleas, or 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 as the Court of Common Please or such court shall deem proper.

Section 3. Indemnification as Matter of Right. To the extent that a director, trustee, officer, employee, or agent has been successful on the merits or otherwise in defense of any action, suit, or proceeding referred to in Sections 1 and 2 of this Article VI, 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.

Section 4. Determination of Conduct. Any indemnification under Sections 1 and 2 of this Article VI, 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, trustee, officer, employee, or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in Sections 1 and 2 of this Article VI. Such determination shall be made (a) by a majority vote of a quorum consisting of directors of the Corporation who were not and are not parties to or threatened with any such action, suit, or proceeding, or (b) if such a quorum is not obtainable or if a majority vote of a quorum of disinterested directors so directs, in a written opinion by independent legal counsel, other than an attorney or a firm having associated with it an attorney who has been retained by or who has performed services for the Corporation or any person to be indemnified within the past five years, or (c) by the shareholders, or (d) by the Court of Common Pleas or the court in which such action, suit, or proceeding was brought.

Section 6. Permissive Advance Payment of Expenses. Expenses, including attorneys’ fees, incurred in defending any action, suit, or proceeding referred to in Sections 1 and 2 of this Article VI, may be paid by the Corporation as they are incurred, in advance of the final disposition of such action, suit, or proceeding as authorized by the directors in the specific case upon receipt of an undertaking by or on behalf of the director, trustee, officer, employee, or agent to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the Corporation as authorized in this Article VI.

Section 7. Nonexclusivity.
