Section 2.02. Annual Meeting. The board of directors may fix the date and time of the annual meeting of the shareholders, but if no such date and time is fixed by the board the meeting for any calendar year shall be held on the 10th day of May in such year, if not a legal holiday under the laws of Pennsylvania, and, if a legal holiday, then on the next succeeding business day, not a Saturday, at 10:00 o’clock A.M., and at said meeting the shareholders then entitled to vote shall elect directors and shall transact such other business as may properly be brought before the meeting. If the annual meeting shall not have been called and held during such calendar year, any shareholder may call such meeting at any time thereafter. Section 2.03. Special Meetings.

At any time, upon written request of any person or persons who have duly called a special meeting, which written request shall state the object of the meeting, it shall be the duty of the secretary to fix the date of the meeting to be held at such date and time as the secretary may fix, not less than five nor more than 60 days after the receipt of the request, and to give due notice thereof. If the secretary shall neglect or refuse to fix the date and time of such meeting and give notice thereof, the person or persons calling the meeting may do so. Section 2.04. Notice of Meetings. Written notice of every meeting of the shareholders, whether annual or special, shall be given to each shareholder of record entitled to vote at the

Every notice of a special meeting shall state briefly the purpose or purposes thereof, and no business, other than that specified in such notice and matters germane thereto, shall be transacted at any special meeting without further notice to shareholders not present in person or by proxy. Whenever the language of a proposed resolution is included in a written notice of a meeting of shareholders the resolution may be adopted at such meeting with such clarifying or other amendments as do not enlarge its original purpose without further notice to shareholders not present in person or by proxy. Section 2.05. Quorum, Manner of Acting and Adjournment. The presence in person or by proxy of shareholders entitled to cast a majority of the votes which all shareholders are entitled to cast on the particular matter shall constitute a quorum for the purpose of considering-such matter. Treasury shares shall not be counted in determining the total number of outstanding shares for voting purposes at any give time. The shareholders present in person or by proxy at a duly organized meeting can continue to do business until adjournment, notwithstanding withdrawal of enough shareholders to leave less than quorum. If a meeting cannot be organized because a quorum has not attended, the shareholders entitled to vote and present in person or represented by proxy may adjourn the meeting to such time and place as they may determine. At any such adjourned meeting at which a quorum may be present such business may be transacted as might have been transacted at the meeting as originally called. No notice of any adjourned meeting of the shareholders of the corporation shall be required to be given, except by announcement at the meeting. In case of any meeting called for the election of directors, 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. Any meeting at which directors are to be elected shall be adjourned only from day to day, or for such longer periods not exceeding 15 days each, as may be directed by shareholders who are present in person or by proxy and who are entitled to cast at least a majority of the vote which all such shareholders would be entitled to cast at an election of directors, until such directors are, Except as otherwise specified in the articles or these by-laws or provided by statute, the acts, at a duly organized meeting, of the shareholders present, in person or by proxy, entitled to cast at least a majority of the votes which all shareholders present in person or by proxy are entitled to cast shall be the acts of the shareholders. Section 2.06. Organization.

3 Section 2.07. Voting. (a) Every shareholder entitled to vote at a meeting of shareholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or persons to act for the shareholder by proxy. (b) Every proxy shall be executed or authenticated by the shareholder or by the duly authorized attorney-in-fact of the shareholder and filed with or transmitted to the secretary of the corporation or its designated agent. A shareholder or his or her duly authorized attorney-in fact may execute or authenticate a writing or transmit an electronic message authorizing another person to act for such shareholder by proxy. A telegram, telex, cablegram, datagram, email, Internet communication or other means of electronic transmission from a shareholder or attorney-in-fact, or a photographic, facsimile or similar reproduction of a writing executed by a shareholder or attorney-in-fact: (1) may be treated as properly executed or authenticated for purposes of this subsection; and (2) shall be so treated if it sets forth or utilizes a confidential and unique identification number or other mark furnished by the corporation to the shareholder for the purposes of a particular meeting or transaction. (c) A proxy, unless coupled with an interest, shall be revocable at will, notwithstanding any other agreement or any provision in the proxy to the contrary, but the revocation of a proxy shall not be effective until notice thereof has been given to the secretary of the corporation. No unrevoked proxy shall be valid after 11 months from the date of its execution, unless a longer time is expressly provided therein, but in no event shall any proxy, unless coupled with an interest, be voted on after three years from the date of its execution. A proxy shall not be revoked by the death or incapacity of the maker unless, before the vote is counted or the authority is exercised, written notice of such death or incapacity is given to the secretary of the corporation. A shareholder shall not sell a vote or execute a proxy to any person for any sum of money or anything of value. A proxy coupled with an interest shall include an unrevoked proxy in favor of a creditor of a shareholder and such proxy shall be valid as long as the debt owed by the shareholder to the creditor remains unpaid. (d) Every shareholder of record except the holder of shares which have been called for redemption and with respect to which an irrevocable deposit of funds has been made, shall have the right, at every shareholders’ meeting, to such a vote for every share, and to such a fraction of a vote with respect to every fractional share of stock in the corporation standing in such shareholder’s name on the books of the corporation as may be provided in the articles, and to one vote for every share, and to a fraction of a vote equal to every fractional share, if no express provision for voting rights is made in the articles. Treasury shares shall not be voted, directly or indirectly, at any meeting of shareholders or be counted in connection with the expression of consent or dissent to corporate action in writing without a meeting. Section 2.08. Voting Lists. The officer or agent of the corporation having charge of the transfer books for shares of the corporation shall make, at least five days before each meeting of shareholders, a complete list of the shareholders entitled to vote at the meeting, arranged in alphabetical order, with the address of and the number of shares held by each, which list shall be kept on file at the registered office of the corporation, and shall be subject to inspection by any

4 shareholder at any time during usual business hours. If the corporation has less than 5000 shareholders, such list shall also be produced and kept open at the time and place of the meeting, and shall be subject to the inspection of any shareholder during the whole time of the meeting. The original share ledger or transfer book, or a duplicate thereof, kept in Pennsylvania, shall be prima facie evidence as to who are the shareholders entitled to examine such list or share ledger or transfer book, or to vote, in person or by proxy, at any meeting of shareholders. Section 2.09. Judges of Election. The vote upon any matter, including the election of directors, need not be by ballot. In advance of any meeting of shareholders the board of directors may appoint judges of election, who need not be shareholders, to act at such meeting or any adjournment thereof. If judges of election are not so appointed, the chairman of any such meeting may, and upon the demand of any shareholder or the shareholder’s proxy at the meeting and before voting begins shall, appoint judges of election. The number of judges shall be either one or three, as determined in the case of judges appointed upon demand of a shareholder, by shareholders present entitled to cast a majority of the votes which all shareholders present are entitled to cast thereon. No person who is a candidate for office shall act as a judge. In case any person appointed as judge fails to appear or fails or refuses to act, the vacancy may be filled by appointment made by the board of directors, in advance of the convening of the meeting, or at the meeting by the chairman of the meeting. If judges of election are appointed as aforesaid, they shall determine the number of shares outstanding and the voting power of each, the shares represented at the meeting, the existence of a quorum, the authenticity, validity and effect of proxies, receive votes or ballots, hear and determine all challenges and questions in any way arising in connection with the right to vote, count and tabulate all votes, determine the result, and do such acts as may be proper to conduct the election or vote with fairness to all shareholders. If there be three judges of election, the decision, act or certificate of a majority shall be effective in all respects as the decision, act or certificate of all. On request of the Chairman of the meeting or of any shareholder or the shareholder’s proxy, the judges shall make a report in writing of any challenge or question or matter determined by them and execute a certificate of any fact found by them. Section 2.10. Determination of Shareholders of Record. The board of directors may fix a date, not more than 90 days preceding the date of any meeting of shareholders, or the date fixed for the payment of any dividend or distribution, or the date for the allotment of rights, or the date when any change or conversion or exchange of shares will be made or go into effect, as a record date for the determination of the shareholders entitled to notice of, or to vote at, any such meeting, or entitled to receive payment of any such dividend or distribution, or to receive any such allotment of rights or to exercise the rights in respect to any such change, conversion or exchange of shares; and in such case, if otherwise entitled, all shareholders of record on the date so fixes, and no others, shall be entitled to notice of, or to vote at, such meeting, or to receive payment of such dividend or distribution or to receive such allotment of rights, or exercise such rights as the case may be, notwithstanding any transfer of any shares on the books of the corporation after any such record date fixes as aforesaid. Unless a record date is fixed by the board of directors for such purpose, transferees of shares which are transferred on the books within ten days next preceding the date of such meeting shall not be entitled to notice of, or to vote at, such meeting.

5 Section 2.11. Consent of Shareholders in Lieu of Meeting. Any action which may be taken at a meeting of the shareholders or of a class of shareholders of the corporation may be taken without a meeting if a consent or consents in writing, setting forth the action so taken, shall be signed by all the shareholders who would be entitled to vote at a meeting of the shareholders or of a class of shareholders for such purpose and shall be filed with the secretary of the corporation. If the articles so provide any action (except any action with respect to an amendment of articles or plan under which a class or classes of shareholders are by statute entitled to claim the right to valuation of and payment for their shares) which may be taken at a meeting of shareholders or of a class of shareholders may be taken without a meeting, if a consent or consent in writing to such action, setting forth the action so taken, shall be signed by shareholders entitled to cast two-thirds of the total number of votes which all shareholders of the corporation or of a class of shareholders are entitled by the articles to cast upon such action and shall be filed within the secretary of the corporation. Such action shall not become effective until after at least ten days’ written notice of such action shall have been given to each shareholder of record entitled to vote thereon. Section 2.12. Business to be Transacted at Shareholder Meetings. No business may be transacted at an annual meeting of shareholders, other than business that is either (a) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the board of directors (or any duly authorized committee thereof), (b) otherwise properly brought before the annual meeting by or at the direction of the board of directors (or any duly authorized committee thereof) or (c) otherwise properly brought before the annual meeting by any shareholder of the corporation (i) who is a shareholder of record on the date of the giving of notice provided for in Section 2.12 and on the record date for the determination of shareholders entitled to vote at such annual meeting and (ii) who complies with the notice procedures set forth in this Section 2.12. In addition to any other applicable requirements, for business to be properly brought before an annual meeting by a shareholder, such shareholder must have given timely notice thereof in proper written form to the secretary of the corporation. To be timely, a shareholder’s notice must be delivered to or mailed and received at the principal executive offices of the corporation not less than 90 days nor more than 120 days prior to the anniversary date of the immediately preceding annual meeting of shareholders; provided, however, that in the event that the annual meeting is called for a date that is not within 30 days before or after such anniversary date, notice by the shareholder, in order to be timely, must be so received not later than the close of business on the tenth day following the day on which such notice of the date of the annual meeting was first mailed. To be in proper written form, a shareholder’s notice to the secretary must set forth as to each matter such shareholder proposes to bring before the annual meeting (i) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting, (ii) the name and record address of such shareholder, (iii) the class or series and number of shares of capital stock of the corporation which are owned beneficially or of record by such shareholder, (iv) a description of all arrangements or understandings between such shareholder and any other person or persons (including their names) in connection with the proposal of such business by such shareholder and any material interest of such shareholder in such business and (v) a representation that such shareholder

6 intends to appear in person or by proxy at the annual meeting to bring such business before the meeting. No business shall be conducted at the annual meeting of shareholders except business brought before the annual meeting in accordance with the procedures set forth in this Section 2.12; provided, however, that once business has been properly brought before the annual meeting in accordance with such procedures, nothing in this Section 2.12 shall be deemed to preclude discussion by any shareholder of any such business. If the chairman of an annual meeting determines that business was not properly brought before the annual meeting in accordance with the foregoing procedures, the chairman shall declare to the meeting that the business was not properly brought before the meeting and such business shall not be transacted. At a special meeting of shareholders, only such business shall be conducted as shall have been set forth in the notice relating to the meeting. At any meeting, matters incident to the conduct of this meeting may be voted upon or otherwise disposed of as the presiding officer of the meeting shall determine to be appropriate. ARTICLE III Board of Directors Section 3.01. Powers; Personal Liability. (a) The board of directors shall have full power to conduct, manage, and direct the business and affairs of the corporation; and all powers of the corporation, except those specifically reserved or granted to the shareholders by statute or by the articles or these by-laws, are hereby granted to and vested in the board of directors. (b) A director of the corporation shall not be personally liable, as such, for monetary damages for any action taken, or any failure to take any action, unless the director has breached or failed to perform the duties of his or her office under 42 Pa.C.S. § 8363 and the breach or failure to perform constitutes self-dealing, willful misconduct or recklessness. The provisions of this subsection shall not apply to the responsibility or liability of a director pursuant to any criminal statute or the liability of a director for the payment of taxes pursuant to local, state or federal law. The provisions of this subsection shall be effective January 27, 1987, but shall not apply to any action filed prior to that date nor to any breach of performance of duty or any failure of performance of duty by a director occurring prior to that date. Section 3.02. Qualification and Election. All directors of the corporation shall be natural persons of full age, but need not be residents of Pennsylvania or shareholders in the corporation. Except in the case of vacancies, directors shall be elected by the shareholders. Upon the demand of any shareholder or the shareholder’s proxy at any meeting of shareholders for the election of directors the chairman of the meeting shall call for and shall afford a reasonable opportunity for the making of nominations for the office of director. Any shareholder or the shareholder’s proxy may nominate as many persons for the office of director as there are positions to be filled. If nominations for the office of director have been called for as herein provided only candidates who have been nominated in accordance therewith shall be eligible for election. Except as otherwise provided in these bylaws, directors of the corporation shall be elected by the shareholders only at an annual meeting of shareholders, unless such election of directors is required by the terms of any series of Preferred Stock or unless such election is made by the

7 Board of Directors to fill a vacancy on the Board. In elections for directors, voting need not be by ballot, unless required by vote of the shareholders before the voting for election of directors begins. In an election of directors, where the board of directors determines that the number of nominees exceeds the number of directorships to be filled, the directors shall be elected by a plurality of the votes cast, even if the number of nominees does not exceed the number of directorships to be filled at the time of any meeting for such election. Except as otherwise provided in the preceding sentence, if in an election of directors in which the number of nominees does not exceed the number of directors to be elected, any nominee who is not an incumbent director receives a plurality of the votes cast but does not receive a majority of the votes cast, the resignation of such nominee referred to in the last two sentences of this Section 3.02 will be automatically accepted. If the nominee is an incumbent director who is standing for re-election and such nominee receives a plurality of the votes cast but does not receive a majority of the votes cast, the independent directors (within the meaning of the NASDAQ corporate governance rules, the “Independent Directors”) will make a recommendation to the board on whether to accept the director’s resignation or whether other action should be taken. The director not receiving a majority of the votes cast will not participate in the Independent Directors’ recommendation or the board’s decision regarding the tendered resignation. The board will consider the Independent Directors’ recommendation and publicly disclose the board’s decision and the basis for that decision within 90 days from the date of the certification of the final election results. For purposes of this paragraph, a majority of the votes cast means that the number of shares voted “for” must exceed the number of shares voted “against” with respect to that director’s election. Each person who is nominated to stand for election as a director shall, as a condition to such nomination, tender an irrevocable resignation in advance of the meeting for the election of directors. Such resignation will be effective if (a) the nominee does not receive a majority vote at the next meeting for the election of directors when required by this Section 3.02, and (b) in the case of a nominee who is an incumbent director, the board accepts the resignation. Section 3.03. Number and Term of Office. The board of directors shall consist of such number of directors, not less than three nor more than nine, as may be determined from time to time by resolution adopted by a vote of three-quarters of the entire board of directors. The board of directors shall be divided into three classes, which shall be as nearly equal in number as possible. Each director shall serve for a term of three years and until a successor shall have been elected and qualified, except in the event of death, resignation or removal. The three initial classes shall serve as provided in the Articles of Incorporation. The number of directors shall never be less than three, except that if all the shares of the corporation are owned beneficially and of record by either one or two shareholders, the number of directors may be less than three but not less than the number of shareholders. Section 3.04. Organization. At every meeting of the board of directors, the chairman of the board, if there be one, or, in the case of a vacancy in the office or absence of the chairman of the board, one of the following officers present in the order stated: the vice chairman of the board, if there be one, the president, the vice presidents in their order of rank and seniority, or a chairman chosen by a majority of the directors present, shall preside, and the secretary, or, in the absence of the secretary, an assistant secretary, or in the absence of the secretary and the assistant secretaries, any person appointed by the chairman of the meeting, shall act as secretary. Section 3.05. Resignations. Any director of the corporation may resign at any time by giving written notice to the president or the secretary of the corporation. Such resignation shall

8 take effect at the date of the receipt of such notice or at any later time specified therein and, unless otherwise specified therein, the acceptance of such resignation shall not be necessary to make it effective. Section 3.06. Vacancies. The board of directors may declare vacant the office of a director if such director be declared of unsound mind by an order of court, or convicted of felony, or for any other proper cause, or if within 60 days after notice of election, the director does not accept such office either in writing or by attending a meeting of the board of directors. Any vacancy or vacancies in the board of directors because of death, resignation, removal, in any manner, other than under the provisions of Section 3.07 of this Article, disqualification, an increase in the number of directors, of any other cause, may be filled by a vote of the majority of the remaining members of the board of directors though less than a quorum, at any regular or special meeting; and the director or directors so elected shall hold office until the next election of the class for which such director shall have been elected and until a successor shall have been elected and qualified, or until death, resignation or removal. Section 3.07. Removal. At any special meeting called for the purpose of removing or electing directors, the entire board of directors, or a class of the board where the board is classified with respect to the power to elect directors, or any individual director may be removed from office without assigning any cause as provided in the Articles of Incorporation. In case the board or such class of the board or any one or more directors be so removed, new directors may be elected at the same meeting. If shareholders are entitled to vote cumulatively for the board or a class of the board, no individual director shall be removed, unless the entire board or class of the board be removed, in case the votes of a sufficient number of shares are cast against the resolution for a removal, which, if cumulatively voted at an annual election of directors, would be sufficient to elect one more directors to the board or to the class. Section 3.08. Place of Meeting. The board of directors may hold its meetings at such place or places within Pennsylvania, or elsewhere as the board of directors may from time to time appoint, or as may be designated in the notice calling the meeting. Section 3.09. Organization Meeting. Immediately after each annual election of directors or other meeting at which the entire board of directors is elected, the newly elected board of directors shall meet for the purpose of organization, election of officers, and the transaction of other business, at the place where said election of directors was held. Notice of such meeting need not be given. Such organization meeting may be held at any other time or place which shall be specified in a notice given as thereinafter provided for special meetings of the board of directors. Section 3.10. Regular Meetings. Regular meetings of the board of directors shall be held at such time and place as shall be designated from time to time by resolution of the board of directors. If the date fixed for any such regular meeting be a legal holiday under the laws of the State where such meeting is to be held, then the same shall be held on the next succeeding business day, not a Saturday, or at such other time as may be determined by resolution of the board of directors. At such meetings, the directors shall transact such business as may properly be brought before the meeting. Notice of regular meetings need not be given. Section 3.11. Special Meetings. Special meetings of the board of directors shall be held whenever called by the chairman of the board, president or by two or more of the directors.

9 Notice of each such meeting shall be given to each director by telephone or in writing at least 24 hours (in the case of notice by telephone) or 48 hours (in the case of notice by telegram) or five days (in the case of notice by mail) before the time at which the meeting is to be held. Every such notice shall state the time and place of the meeting. Notice of any special meeting of the board of directors during any emergency resulting from warlike damage or an attack on the United States or any nuclear or atomic disaster shall be given only to such of the directors as it may be feasible to reach at the time and by such means as may be feasible at the time, including publication or radio. Section 3.12. Quorum. Manner of Acting. and Adjournment. A majority of the directors in office shall be present at each meeting in order to constitute a quorum for the transaction of business. Except as otherwise specified in the articles or these by-laws or provided by statute, the acts of a majority of the directors present at a meeting at which a quorum is present shall be the acts of the board of directors. In the absence of quorum, a majority of the directors present may adjourn the meeting from time to time until a quorum be present, and no notice of any adjourned meeting need be given, other than by announcement at the meeting. The directors shall act only as a board and the individual directors shall have no power as such, provided, however, that any action which may be taken at a meeting of the board may be taken without a meeting if a consent or consents in writing setting forth the action so taken shall be signed by all of the directors and shall be filed with the secretary of the corporation. To the extent required to constitute a quorum at any meeting of the board of directors during any emergency resulting from warlike damage or an attack on the United States or any nuclear or atomic disaster the officers of the corporation who are present shall be deemed in order of rank and within the same rank in order of seniority, directors for such meeting. Section 3.13. Executive and Other Committees. The board of directors, by resolution adopted by a majority of the whole board, may designate an Executive Committee, a Compensation Committee, an Audit Committee and one or more other committees, each committee to consist of two or more directors. The board may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member of any meeting of the committee. In the absence or disqualification of a member, and the alternate or alternates, if any, designated for such member, of any committee the member or members thereof present at any meeting and not disqualified from voting, whether or not the member or members present constitute a quorum, may unanimously appoint another director to act at the meeting in the place of any such absent or disqualified member. Except as otherwise provided in this section, the Executive Committee shall have and exercise all of the authority of the board in the management of the business and affairs of the corporation and any other committee shall have and exercise the authority of the board to the extent provided in the resolution designating the committee. No such committee of the board shall have the authority of the board in reference to: (1) Amending the by-laws of the corporation; (2) Declaring any dividend; (3) Issuing any authorized but unissued share;

In the case of all committees other than the Executive Committee, a majority of the directors in office designated to such committee, or directors designated to replace them as provided in this section, shall be present at each meeting to constitute a quorum for the transaction of business and the acts of a majority of the directors in office designated to such committee or their replacements shall be the acts of the committee. Each committee shall keep regular minutes of its proceedings and report such proceedings periodically to the board of directors. Unless otherwise provided in a resolution or charter approved by the board, Sections 3.10, 3.11 and 3.12 shall be applicable to each committee of the board of directors. Subject to the foregoing limitations and provisions, the Executive Committee shall have and exercise the authority of the board set forth in this Section 3.14, and any other committee shall have and exercise the authority of the board to the extent provided in the resolution designating the committee or in the charter of such committee which has been approved by the board.

ARTICLE VII Indemnification of Directors, Officers, Etc. Section 7.01. Scope of Indemnification. (a) The corporation shall indemnify an indemnified representative against any liability incurred in connection with any proceeding in which the indemnified representative may be involved as a party or otherwise, by reason of the fact that such person is or was serving in an indemnified capacity, including without limitation liabilities resulting from any actual or alleged breach or neglect of duty, error, misstatement or misleading statement, negligence, gross negligence or act giving rise to strict or products liability, except where such indemnification is expressly prohibited by applicable law or where the conduct of the indemnified representative has been determined pursuant to Section 7.06 to constitute willful misconduct or recklessness within the meaning of 42 Pa.C.S. § 8365(b) or any superseding provision of law, sufficient in the circumstances to bar indemnification against liabilities arising from the conduct. (b) If an indemnified representative is entitled to indemnification in respect of a portion, but not all, of any liabilities to which such person may be subject, the corporation shall indemnify such indemnified representative to the maximum extent for such portion of the liabilities. (c) The termination of a 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 indemnified representative is not entitled to indemnification. (d) For purposes of this Article: (1) “indemnified capacity” means any and all past, present and future service by an indemnified representative in one or more capacities as a director, officer, employee or agent of the corporation, or, at the request of the corporation, as a director, officer, employee, agent, fiduciary or trustee of another corporation, partnership, joint venture, trust, employee benefit plan or other entity or enterprise; (2) “indemnified representative” means any and all directors and officers of the corporation and any other person designated as an indemnified representative by the board of directors of the corporation (which may, but need not, include any person serving at the request of the corporation, as a director, officer, employee, agent, fiduciary or trustee of another corporation, partnership, joint venture, trust, employee benefit plan or other entity or enterprise);

16 (3) “liability” means any damage, judgment, amount paid in settlement, fine, penalty, punitive damages, excise tax assessed with respect to an employee benefit plan, or cost or expense of any nature (including, without limitation, attorneys’ fees and disbursements); and (4) “proceeding” means any threatened, pending or completed action, suit, appeal or other proceeding of any nature, whether civil, criminal, administrative or investigative, whether formal or informal, and whether brought by or in the right of the corporation, a class of its security holders or otherwise. Section 7.02. Proceedings Initiated by Indemnified Representatives. Notwithstanding any other provision of this Article, the corporation shall not indemnify under this Article an indemnified representative for any liability incurred in a proceeding initiated (which shall not be deemed to include counter-claims or affirmative defenses) or participated in as an intervenor or amicus curiae by the person seeking indemnification unless such initiation of or participation in the proceeding is authorized, either before or after its commencement, by the affirmative vote of a majority of the directors in office.

Section 7.03. Advancing Expenses. The corporation shall pay the expenses (including attorneys’ fees and disbursements) incurred in good faith by an indemnified representative in advance of the final disposition of a proceeding described in Section 7.01 or 7.02 upon receipt of an undertaking by or on behalf of the indemnified representative to repay such amount if it shall ultimately be determined pursuant to Section 7.06 that such person is not entitled to be indemnified by the corporation pursuant to this Article. The financial ability of an indemnified representative to repay an advance shall not be a prerequisite to the making of such advance. Section 7.04. Securing of Indemnification Obligations.

17 the second of whom shall be selected by the indemnified representative and the third of whom shall be selected by the other two arbitrators. In the absence of the American Arbitration Association, or if for any reason arbitration under the arbitration rules of the American Arbitration Association cannot be initiated, or if one of the parties fails or refuses to select an arbitrator, or if the arbitrators selected by the corporation and the indemnified representative cannot agree on the selection of the third arbitrator within 30 days after such time as the corporation and the indemnified representative have each been notified of the selection of the other’s arbitrator, the necessary arbitrator or arbitrators shall be selected by the presiding judge of the court of general jurisdiction in such metropolitan area.

This arbitration provision shall be specifically enforceable. Section 7.07. Contribution.

Section 7.08. Discharge of Duty.
