by the shareholders.

                                       -3-

four (4) days' notice to each director, either personally, by mail or by

constitute a waiver of notice of such meeting, unless the director, at the
beginning of the meeting (or promptly upon his arrival), objects to holding the
meeting or transacting business at the meeting, and does not thereafter vote for
or assent to action taken at the meeting. 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 the notice of such meeting.

Section 6.        One of the directors shall constitute a quorum for the
transaction of business, unless a greater number is required by law or by the
articles of incorporation. The act of a majority of the directors present at any
meeting at which a quorum is present shall be the act of the board of directors,
unless the act of a greater number is required by statute or by the articles of
incorporation. If a quorum shall not be present at any meeting of directors, the
directors present thereat may adjourn the meeting from time to time until a
quorum shall be present.

Section 1.        Whenever notice is required to be given to any director or
shareholder under the provisions of the statutes, the articles of incorporation
or these by-laws, it shall be construed to mean written notice, which may be by
mail, addressed to such director or shareholder, at his address as it appears on
the records of the corporation, with postage thereon prepaid, and such notice
shall be deemed to be given at the time it is deposited in the United States
mail. Notice to directors may also be given by telegram.
