         SECTION 2.4. NOTICE OF MEETINGS. Written notice of every meeting of
stockholders, stating the place, date and hour thereof and, in the case of a

standing in his name on the books of the Corporation as of the record date fixed
by the Board of Directors or prescribed by law and, if a quorum is present, a
majority of the shares of such stock present or represented at any meeting of

giving the proxy or by his duly authorized attorney. No proxy shall be valid
after the expiration of three (3) years from its date, unless a longer period is
provided for in the proxy. Unless and until voted, every proxy shall be
revocable at the pleasure of the person who executed it, or his legal
representatives or assigns except in those cases where an irrevocable proxy

thereof is required or permitted to be taken in connection with any corporate
action by any provision of statute, the Certificate of Incorporation or these
By-Laws, the meeting, prior notice thereof and vote of stockholders may be

of votes that would have been necessary to authorize or take such action at a
meeting at which all shares entitled to vote thereon were present and voted
shall consent in writing to the taking of such action. Where corporate action is
taken in such matter by less than unanimous written consent, prompt written
notice of the taking of such action shall be given to all stockholders.
