STOCKHOLDERS’ MEETINGS

SECTION 1. Annual Meetings. The annual meetings of the stockholders of the corporation, commencing with the year 1984, shall be held at such place within or without the State of New Jersey as may be fixed by resolution of the Board of Directors and as shall be designated in the notice of said meeting, on such date and at such time as the Board of Directors may also fix by resolution, or if the Board of Directors fails to set a date and time, on the third Tuesday of August at 12:00 Noon, if not a legal holiday, and if such day is a legal holiday, then such meeting shall be held on the next business day.

At each annual meeting of stockholders there shall be held an election of directors and such other business as may properly come before it. Failure of the Board to fix the date of or to hold the annual meeting as designated, or to elect a sufficient number of directors at such meeting or any adjournment thereof, shall not otherwise affect the

corporate acts of the Board. If the annual meeting for election of directors is not held on the date designated therefor, the directors shall cause the meeting to be held as soon thereafter as convenient.

A notice of any change in the time or place of a meeting for the election of directors shall be given to each stockholder entitled to vote at the meeting, at least ten days before the election is held, in person or by mail.

SECTION 2. Special Meetings. Special meetings of the stockholders shall be held at the principal office of the corporation in the State of New Jersey, or at such other place within or without the State of New Jersey as may be designated in the notice of said meeting by the Chairman or by the Board of Directors and upon call of the Chairman or the Board of Directors. It shall be the duty of the Chairman or the Board of Directors to order and call such meetings whenever persons holding one-fourth of the capital stock of the corporation outstanding shall in writing request the same. Such special meetings shall be held at such place and in the same manner as in the case of the annual meeting of stockholders.

SECTION 3. Notice and Purpose of Meetings. Notice of the purpose or purposes and of the time and place within or without the State of New Jersey of every meeting of stockholders shall be in writing and signed by the President

- 2 -

or Vice-President or the Secretary or an Assistant Secretary and a copy thereof shall be sent by mail not less than ten days before the meeting, to each stockholder of record entitled to vote at such meeting. Such notice shall be directed to each stockholder at his address as it appears on the stock transfer books. Such further notice shall be given as may be required by law. Except as otherwise expressly provided by statute, no publication of any notice of a meeting of stockholders shall be required. Notice of any meeting of stockholders shall not be required to be given to any stockholder who shall attend such meeting in person or by proxy, or who shall, in person or by attorney thereunto authorized, waive such notice in writing or by telegraph, cable, radio, or wireless either before or after such meeting. Except where otherwise required by law, notice of any adjourned meeting of the stockholders of the corporation shall not be required to be given.

SECTION 4. Quorum. At all meetings of stockholders, unless otherwise determined by law or the Certificate of Incorporation, the presence in person or by proxy of stockholders entitled to cast at least a majority of the votes which all stockholders are entitled to cast on the particular matter, shall constitute a quorum for the purpose of considering such matter. In the absence of a quorum at any meeting or any adjournment thereof, a majority of those

- 3 -

present in person or by proxy and entitled to vote may adjourn such meeting for a period not exceeding twenty days. At any such adjourned meeting at which a quorum is present, any business may be transacted which might have been transacted at the meeting as originally called.

SECTION 5. Organization and Conduct. Meetings of the stockholders shall be presided over by the Chairman of the Board, or if he is not present, by the President, or if he is not present, by a Vice-President, or if neither the Chairman, the President or a Vice-President is present, by a Chairman to be chosen by a majority of the stockholders entitled to vote who are present in person or by proxy at the meeting. The Secretary of the corporation, or in his absence, an Assistant Secretary, shall act as Secretary of every meeting.

Meetings of the stockholders shall be conducted in any orderly manner determined by the Chairman of the meeting, and his determination on any point of order and any ruling made by him shall be conclusive and non-reviewable.

SECTION 6. Voting. Except as otherwise provided in the By-Laws, the Certificate of Incorporation, or in the laws of the State of New Jersey, at every meeting of the stockholders, each stockholder of the corporation entitled to vote at such meeting shall have one vote in person or by proxy for each share of stock having voting rights held by

- 4 -

him. Any vote on stock of the corporation may be given by the stockholder entitled thereto in person or by his proxy appointed by an instrument in writing, subscribed by such stockholder or by his attorney thereunto authorized and delivered to the Secretary of the meeting, if he shall so request, provided, however, that no proxy shall be voted on after three years from its date unless said proxy provides for a longer period. Except as otherwise required by statute, by the Certificate of Incorporation or these By-Laws, all matters coming before any meeting of the stockholders shall be decided by the vote of a majority in interest of the stockholders of the corporation present in person or by proxy at such meeting and entitled to vote thereat, a quorum being present. At all elections of directors the voting may but need not be by ballot, and the persons receiving the greatest number of votes shall be the directors of the corporation. The poll at all elections of directors shall be opened in accordance with the laws of the State of New Jersey.

SECTION 7. List of Stockholders and Books. The directors shall cause the Secretary, or other officer designated by them, who has charge of the transfer books and the stock books, to make, at least ten days before every election after the first election, a full, true and complete list, in alphabetical order, of all the stockholders

- 5 -

entitled to vote at the ensuing election, and the post-office address and the number of shares held by each. Such list shall at all times during the usual hours for business be kept at the principal office in the State of New Jersey, open to the examination of any stockholder. Such books shall be the only evidence as to who are the stockholders entitled to examine such books or list, and to vote at the election. The Board of Directors shall produce such books and list at the time and place of election, to remain there during the election. Photographs or microphotographs of such books shall have the same force and effect as the original thereof.

SECTION 8. Inspectors of Election. At all elections of directors, or in any other case in which inspectors may act, two inspectors of election shall be appointed by the Chairman of the meeting. The inspectors of election shall take and subscribe an oath faithfully to execute the duties of inspectors at such meeting with strict impartiality and according to the best of their ability, and shall take charge of the polls and after the vote shall have been taken shall make a certificate of the result thereof, but no director or candidate for the office of director shall be appointed as such inspector. If there be a failure to appoint inspectors or if any inspector appointed be absent or refuse to act, or if his office becomes vacant, the stockholders present at the meeting, by a per capita vote, may choose temporary inspectors of the number required.

- 6 -

In case the right to vote upon any share of stock is questioned, the inspectors of the election shall refer to the stock books of the corporation to ascertain who are the stockholders, and in the case of a discrepancy between the books, the transfer book shall control and determine who are entitled to vote.

The Board of Directors may also require such owner to execute and deliver to the corporation a bond with or without surety, in such sum as the Board may direct, indemnifying the corporation against any claim that may be made against it by reason of the issue of such new certificate or certificates, and against any other liability or loss in the premises.

SECTION 3. Upon compliance with any provisions restricting the transferability of shares that may be set forth in these By-Laws, or in any written agreement between the corporation and the holder in respect thereof, shares of stock of the corporation shall be transferred only on the books of the corporation by the holder thereof in person, or by his attorney, upon the surrender and cancellation of certificates for a like number of shares.

a meeting, or the date fixed for the payment of any dividend or for the allotment of rights or for the delivery of evidences of rights or evidences of interests arising out of any change, conversion or exchange of capital stock, as the time as of which stockholders entitled to notice of and to vote at such meetings or whose consent or dissent is required or may be expressed for any purpose or entitled to receive any such dividend, distribution, rights or interests shall be determined; and all persons who are holders of record of voting stock at such time and no others shall be entitled to notice of and to vote at such meeting or to express their consent or dissent, as the case may be, and only stockholders of record at the time so fixed shall be entitled to receive such dividend, distribution rights or interests.
