Meetings may be held at any time without notice if all of the Directors are present and no Director is attending for the express purpose of objecting to the transaction of any business because the meeting is not lawfully called or convened, or if those not present waive notice in writing either before or after the meeting. The notice of meetings of the Board need not state the purpose of the meeting except as otherwise required by law.

(c) A majority of the members of any Committee serving at the time of any meeting thereof shall constitute a quorum for the transaction of business at such meeting. The

action of a majority of those members present at a Committee meeting at which a quorum is present shall constitute the act of the Committee.
