Section 2. Special Meetings. Special meetings of the shareholders of the Corporation may be called by the Chairman of the Board, the Chief Executive Officer, or by a majority of the directors then in office, and shall be called by the Secretary upon the written request of the shareholders of record holding at least two-thirds in number of the issued and outstanding shares of the Corporation entitled to vote at such meeting. Special meetings shall be held at such place within or without the State of New York and at such time on such date as shall be specified in the call thereof.

Section 3. Notice of Meetings. Written notice of each annual or special meeting of shareholders stating the place, date and hour thereof and, if it is for a special meeting, the purpose or purposes for which the meeting is called and the person or persons issuing or directing the call thereof, shall be delivered personally or shall be mailed, not less than ten nor more than fifty days before the date of such meeting, to each person who appears on the books of the Corporation as a shareholder entitled to vote at such meeting. Such notice, if mailed, shall be directed to the shareholders at his address as it appears on the record of shareholders, or, if he shall have filed with the Secretary a written request that notices to him be mailed to some other address, at such other address. If, at any meeting of shareholders, action is proposed to be taken which would, if taken, entitle shareholders fulfilling the requirements of Section 623 of the Business Corporation Law to receive payment for their shares, the notice of such meeting shall include a statement of that purpose and to that effect. Whenever all the shareholders entitled to vote at any meeting of shareholders shall have waived notice of such meeting either before or after such meeting, such meeting shall be valid for all purposes. A shareholder who shall be present in person or represented by proxy at any meeting and who shall not have protested prior to the conclusion of the meeting the lack of notice thereof shall be deemed to have waived notice of such meeting. At any annual meeting of shareholders, any business whatsoever that shall be brought before the meeting may be transacted whether or not referred to in the notice of the meeting. If the notice of a special meeting of shareholders shall state as a purpose of the meeting the transaction of any business whatsoever, any corporate action may validly be taken at such meeting. If any meeting of shareholders is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place to which the meeting is adjourned are announced at the meeting at which the adjournment is taken, and at the adjourned meeting any business may be transacted that might have been transacted

on the original date of the meeting. However, if after such adjournment the Board of Directors shall fix a new record date for the adjourned meeting, a notice of the adjourned meeting shall be given to each shareholder of record on the new record date entitled to vote at such meeting.

Section 4. Quorum. At any meeting of shareholders a quorum for the transaction of any business shall consist of the holders, present in person or represented by proxy, of a majority in number of the issued and outstanding shares of the Corporation entitled to vote at such meeting. If there shall not be a quorum at any meeting of shareholders, the holders of a majority in number of the shares entitled to vote present in person or represented by proxy at such meeting may adjourn such meeting from time to time, without notice other than announcement at such meeting, until holders of the amount of shares required to constitute a quorum shall be present in person or represented by proxy.

Section 5. Voting. Each share entitled to vote on any matter before any meeting of shareholders, present in person or represented by proxy, shall carry the right to one vote upon such matter.

Section 6. Record Date. The Board of Directors may prescribe a date, which date shall not be more than fifty nor less than ten days before the date of such meeting, as the record date for the purpose of determining the shareholders entitled to notice of or to vote at any meeting of shareholders or any adjournment thereof. The Board of Directors also may prescribe a date, which date shall not be more than fifty days prior to such action, as the record date for the purpose of determining the shareholders entitled to express consent to or dissent from any proposal without a meeting, or for the purpose of determining shareholders entitled to receive payment of any dividend or the allotment of any rights, or for the purpose of any other action.

Section 7. Inspectors. The Board of Directors, in advance of any meeting of shareholders, may appoint one or more inspectors to act at such meeting or any adjournment thereof. If inspectors are not so appointed, the person presiding at the meeting of shareholders may, and on the request of any shareholder entitled to vote thereat shall, appoint inspectors. If appointed on the request of one or more shareholders, the holders of a majority of shares present and entitled to vote thereat shall determine the number of inspectors to be appointed. If any person so appointed fails to appear or act, the vacancy may be filled by appointment made by the Board of Directors in advance of the meeting or at the meeting by the person presiding thereat. Each inspector, before entering upon the discharge of his duties, shall take and sign an oath faithfully to execute the duties of inspector at such meeting with strict impartiality and according to the best of his ability. The inspectors so appointed shall determine the number of shares outstanding and voting power of each, the shares represented at the meeting, the existence of a quorum, the validity and effect of proxies, and shall receive votes, ballots or consents, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes, ballots or consents, determine the results and do such acts as are proper to conduct the election or vote with fairness to all shareholders. On request of the person presiding at the meeting or any shareholder entitled to vote thereat, the inspectors shall make a report in writing of any challenge, 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 and of the vote as certified by them.
