nonparticipating after the satisfaction of any such rights and preferences;

                  (iv)     The full or  limited  voting  rights,  if any,  to be
provided for shares of such series, in addition to the voting rights provided by
law;

                  (v)      The times,  terms and conditions,  if any, upon which
shares of such series shall be subject to  redemption,  including the amount the
shareholders of such series shall be entitled to receive upon redemption  (which
amount may vary under different conditions or at different redemption dates) and
the  amount,  terms,  conditions  and  manner  of  operation  of  any  purchase,
retirement or sinking fund to be provided for the shares of such series;

class or classes or of any other  series of the same class,  the prices or rates
of  conversion or exchange,  and  adjustments  thereto,  and any other terms and
conditions applicable to such conversion or exchange;

                  (vii)    The limitations, if any, applicable while such series
is outstanding on the payment of dividends or making of distributions on, or the
acquisition  or redemption  of, Common Stock or  restrictions,  if any, upon the
issue of any additional  shares  (including  additional shares of such series or
any other series or of any other class) ranking on a parity with or prior to the
shares of such series either as to dividends or upon liquidation; and
