Voted:   That, upon approval of the proposed one-for-ten reverse stock split of
         the Corporation's Common Stock, par value $.001 per share, Article 3 of
         the Corporation's Articles of Organization as amended to date, shall be
         amended as follows:

         Article 3 shall be amended so that the Corporation shall be authorized
         to issue one class of stock to be designated "Common stock". The total
         number of shares of Common Stock which the Corporation shall have
         authority to issue is Two Million (2,000,000) with a par value of one
         cent ($.01) per share.

         At the effective time of this amendment each share of Common Stock, par
         value $0.001 per share,  authorized immediately prior to this amendment
         shall be reclassified  into one-tenth of one fully paid  non-assessable
         share of Common  Stock,  par value  $0.01 per share,  so that every ten
         shares  of  common  Stock  par  value  $0.001  per  share,   authorized
         immediately  prior to this amendment shall be combined together to form
         on full share of Common  Stock par value $0.01 par share.  Certificates
         for fractional  shares of Common Stock will not be issued by reason for
         this  amendment  and  instead  a  whole  share  will be  issued  to any
         stockholder entitled to a fraction of a share.
