At any time, upon written request of any person entitled to call a special meeting of the shareholders, it shall be the duty of the Secretary to call a special meeting to be held at such time as the Secretary may fix. If the Secretary shall neglect or refuse to issue such call, the person or persons making the request may do so.

Section 4. NOTICE. Except as provided in this Section 4, written notice of every meeting of the shareholders shall be given by, or at the direction of, the secretary or other authorized person or, if they neglect or refuse to do so, may be given by the person or persons calling the meeting, to each shareholder of record entitled to vote at the meeting, at least five (5) days prior to the day named for a meeting, unless a greater period of notice is required by statute

(3) Notwithstanding anything in the second sentence of Section 8(a)(2) of this Article III to the contrary, in the event that the number of directors to be elected to the Board of Directors of the Corporation is increased and there is no public announcement naming all of the nominees for director or specifying the size of the increased Board of Directors made by the Corporation at least 100 days prior to the first anniversary of the preceding year’s annual meeting, a shareholder’s notice required by this By-Law shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of business on the 10th day following the day on which such public announcement is first made by the Corporation.

(b) Special Meetings of Shareholders.

Only such business shall be conducted at a special meeting of shareholders as shall have been brought before the meeting pursuant to the Corporation’s notice of meeting. Nominations of persons for election to the Board of Directors may be made at a special meeting of shareholders at which directors are to be elected pursuant to the Corporation’s notice of meeting (a) by or at the direction of the Board of Directors or (b) provided that the Board of Directors has determined that directors shall be elected at such meeting, by any shareholder of the Corporation who is a shareholder of record at the time of giving of notice provided for in this By-Law, who shall be entitled to vote at the meeting and who complies with the notice procedures set forth in this By-Law. In the event the Corporation calls a special meeting of shareholders for the purpose of electing one or more directors to the Board of Directors, any such shareholder may nominate a person or persons (as the case may be), for election to such position(s) as specified in the Corporation’s notice of meeting, if the shareholder’s notice required by Section 8(a)(2) of this Article III with respect to any nomination (including the completed and signed questionnaire, representation and agreement required by Section 8(c) of this Article III) shall be delivered to the

5

Secretary at the principal executive offices of the Corporation not earlier than the close of business on the 10th day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting. In no event shall the public announcement of an adjournment or postponement of a special meeting commence a new time period for the giving of a shareholder’s notice as described above. This paragraph (b) shall be the exclusive means for a shareholder to make nominations or other business proposals before a special meeting of shareholders (other than matters properly brought under Rule 14a-8 under the Exchange Act and included in the Corporation’s notice of meeting).

(c) Submission of Questionnaire, Representation and Agreement.

To be eligible to be a nominee of a shareholder for election or reelection as a director of the Corporation, a person must deliver (in accordance with the time periods prescribed for delivery of notice under Section 8(a)(1)(b) or Section 8(b) of this Article III) to the Secretary at the principal executive offices of the Corporation a written questionnaire with respect to the background and qualifications of such person and the background of any other person or entity on whose behalf the nomination is being made (which questionnaire shall be provided by the Secretary upon written request) and a written representation and agreement (in the form provided by the Secretary upon written request) that such person (A) is not and will not become a party to (1) any agreement, arrangement or understanding with, and has not given any commitment or assurance to, any person or entity as to how such person, if elected as a director of the Corporation, will act or vote on any issue or question (a “Voting Commitment”) that has not been disclosed to the Corporation or (2) any Voting Commitment that could limit or interfere with such person’s ability to comply, if elected as a director of the Corporation, with such person’s fiduciary duties under applicable law, (B) is not and will not become a party to any agreement, arrangement or understanding with any person or entity other than the Corporation with respect to any direct or indirect compensation, reimbursement or indemnification in connection with service or action as a director that has not been disclosed therein, (C) in such person’s individual capacity and on behalf of any person or entity on whose behalf the nomination is being made, would be in compliance, if elected as a director of the Corporation, and will comply with all applicable publicly disclosed corporate governance, conflict of interest, confidentiality and stock ownership and trading policies and guidelines of the Corporation and (D) will abide by the requirements these By-Laws.

Except as otherwise provided by law, the articles of incorporation or the By-Laws of the Corporation, the presiding officer of the meeting shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made, or proposed, as the case may be, in accordance with the procedures set forth in these By-Laws and, if any proposed nomination or

6

(3) Notwithstanding the foregoing provisions of this Section 8 of this Article III, a shareholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in Section 8 of this Article III. Nothing in Section 8 of this Article III shall be deemed to affect any rights of shareholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act. Subject to Rule 14a-8 under the Exchange Act, nothing in these By-Laws shall be construed to permit any shareholder, or give any shareholder the right, to include or have disseminated or described in the Corporation’s proxy statement any nomination of director or directors or any other business proposal.

Section 9. ELECTION OF DIRECTORS. Election of directors need not be by ballot, except upon demand by a shareholder made at the election and before the voting begins. In each election for directors every shareholder entitled vote shall have the right in person or by proxy to multiply the number of shares which the shareholder is entitled to vote by the number of directors to be elected in that election, and cast the whole number of votes so determined for one candidate or distribute them among any two or more candidates in that election.

Section 10. ORDER OF BUSINESS.

A telegram, telex, cablegram, datagram, e-mail or Internet communication or other similar 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 shall be treated as properly executed for purposes of this section; provided such transmission or reproduction sets forth 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.

Section 12. JUDGES OF ELECTION. 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 presiding officer of any such meeting may, and on the request of any shareholder shall, make such

7

appointment at the meeting. The number of judges shall be one or three. No person who is a candidate for office to be filled at the meeting shall act as a judge.

The judge or judges of election shall perform their duties impartially, in good faith, to the best of their ability, and as expeditiously as is practical. If there are 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 presiding officer of the meeting, or of any shareholder, the judge or 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. Any report or certificate made by them shall be prima facie evidence of the facts stated therein.

Section 2. CLASSIFICATION. The directors shall be classified with respect to the time for which they shall severally hold office by dividing them into three classes as nearly equal in number as possible.

Unless sooner removed by the Board of Directors, all officers shall hold office for the term fixed by the Board and until their successors are elected and qualified or until their earlier death or resignation. Any two or more offices may be held by the same person, except the office of President and Secretary, but in no case shall the same person act in the same matter in two such official capacities.

Section 8. REMOVAL OF OFFICERS. Any officer or agent of the Corporation may be removed by the Board of Directors with or without cause, but such removal shall be without prejudice to the contract rights, if any, of the person so removed.

Section 9. COMMITTEES. The Board of Directors may from time to time by resolution adopted by a majority of the directors in office, designate one or more committees, each committee to consist of two or more of the directors of the Corporation. The Board may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. Any such committee to the extent provided in the designating resolution of the Board of Directors shall have and exercise the authority of the Board of Directors in the management of the business and affairs of the

Corporation except that a committee shall not have any power or authority as to: (i) the submission to shareholders of any action requiring the approval of shareholders pursuant to the Business Corporation Law, as it may hereafter be amended, (ii) the creation or filling of vacancies in the Board of Directors, (iii) the adoption, amendment or repeal of the By-Laws, (iv) the amendment, adoption or repeal of any resolution of the Board that by its terms is amendable or repealable only by the Board, or (v) action on matters committed by the By-Laws or resolution of the Board to another committee of the Board. In the absence or disqualification of any member of such committee or committees, the member or members thereof present at any meeting and not disqualified from voting, whether or not he or they constitute a quorum, may unanimously appoint another director to act at the meeting in the place of any such absent or disqualified member. Each committee of the Board shall serve at the pleasure of the Board. Unless the Board of Directors provides otherwise by resolution each committee shall conduct its business and take action in the same manner as the Board conducts its business pursuant to the articles of the Corporation and these By-Laws.
