The board of directors may provide by resolution the time and place, either within or without the State of Illinois, for the holding of such additional regular meetings of the board of directors without other notice than such resolution. 4. Special meetings of the board of directors may be called by or at the request of the chairman of the board of directors, the president, or any two directors.

Notice of any special meeting shall be given at least three days previous thereto by written notice delivered personally or mailed to each director at his business address, or by telegram. If mailed, such notice shall be deemed to be delivered when deposited in the United States mail in a sealed envelope so addressed, with postage thereon prepaid. If notice be given by telegram, such notice shall be deemed to be delivered when the telegram is delivered to the telegraph company. Any director may waive notice of any meeting. The attendance of a director at any meeting shall constitute a waiver of notice of such meeting, except where a director attends a meeting for the express purpose of objecting to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the board of directors need be specified in the notice or waiver of notice of such meeting. 6. A majority of the board of directors shall constitute a quorum for the transaction of business at any meeting of the board of directors, provided, that if less than a majority of the directors are present at the said meeting, a majority of the directors present may adjourn the meeting from time to time without further notice. 7. The act of the majority of the directors present at a meeting at which a quorum is present shall be the act of the board of directors. 8. Any vacancies in the membership of the board of directors arising between meetings of shareholders by reason of an increase in the number of directors or otherwise may be filled by vote of a majority of the directors then in office, any director so elected to serve until the next annual meeting of shareholders; provided, however, that at no time shall the number of directors so elected exceed 33-1/3 % of the total membership of the board of directors. 9. Directors as such shall not receive any stated salaries for their services but by resolution of the board of directors a fixed sum and expenses of attendance, if any, may be allowed for attendance at each regular or special meeting of the board of directors. By resolution of the board of directors, a fixed sum and expenses of attendance, if any, may be allowed members of any committee of the board of directors for attendance at any meeting of such committee. In addition, the board may allow by resolution a fixed monthly sum payable to such director or directors as are not officers or employees of the corporation. This sum shall be in an amount which in the opinion of the board of directors adequately compensates such director or directors for extended consideration of corporation matters implicit in the office of such director. Nothing herein contained shall be construed to preclude any director from serving the corporation in any other capacity and receiving compensation therefor. ARTICLE IV EXECUTIVE COMMITTEE 1. The board of directors by resolution adopted by a majority of the whole board may designate two or more directors to constitute an executive committee. The designation of such committee and the delegation thereto of authority shall not operate to relieve the board of directors or any member thereof of any responsibility imposed upon it or him by law. 2.
