dividends provided therefor pursuant to paragraph 1 hereof.

                  3.  Redemption and Repurchase of Preferred Stock

                  If, on or before  the  redemption  date  with  respect  to any
shares of any series of Preferred Stock that are subject to redemption, as fixed
or determined  pursuant to paragraph 1 hereof,  this  corporation  shall deposit
with a bank, trust company or other financial  institution  monies necessary for
the redemption of such shares,  then,  notwithstanding  that any certificate for
such shares so redeemed shall not have been surrendered for  cancellation,  from
and after such redemption  date, all rights and preferences with respect to such
shares so redeemed shall  forthwith on such redemption date cease and terminate,
except  only the right of the holders  thereof to receive,  out of the monies so
deposited,  the amount payable upon redemption of such shares, without interest.
Any such monies so deposited by this corporation and unclaimed at the end of six
(6) years from such redemption date shall be repaid to this corporation upon its
request,  after  which  repayment  the  holders  of the  shares  so  called  for
redemption shall look only to this corporation for the payment thereof.

                  Nothing herein  contained  shall limit any legal right of this
corporation to purchase or otherwise  acquire any shares of the Preferred  Stock
to the extent permitted by law. All or any shares of Preferred Stock at any time
redeemed, purchased or otherwise acquired by this corporation may thereafter, in
the discretion of the Board of Directors,  be reissued or otherwise  disposed of
at any  time or from  time to  time,  to the  extent  and in the  manner  now or
hereafter permitted by law.

                  4.  Dividends on Common Stock

                  Subject  to the  rights  and  preferences  of each  series  of
Preferred  Stock, as determined  pursuant to paragraph 1 hereof,  such dividends
(payable  in cash,  stock or  otherwise)  as may be  determined  by the Board of
Directors  may be declared and paid on the Common  Stock,  but only out of funds
legally available for the payment of such dividends.

                  5.  Distributions on Common Stock.

                  In the event of any liquidation,  dissolution or winding up of
this  corporation,  and subject to the rights and  preferences of each series of
Preferred  Stock, as determined  pursuant to paragraph 1 hereof,  all assets and
funds of this corporation remaining after paying or providing for the payment of




all creditors of this corporation shall be divided among and paid to the holders
of the Common Stock according to their respective shares.

                  6.  Preemptive Rights.

                  No holder of  shares of any stock of this  corporation  of any
class  now or  hereafter  authorized  shall  have any  right as such  holder  to
purchase,  subscribe  for or  otherwise  acquire  any  shares  of  stock of this
corporation  of  any  class  now or  hereafter  authorized,  or  any  securities
convertible into or exchangeable  for any such shares,  or any warrants or other
instruments evidencing rights or options to subscribe for, purchase or otherwise
acquire any such shares, whether such shares, certificates, securities, warrants
or other  instruments  be  unissued  or issued and  thereafter  acquired by this
corporation  and whether such shares and other  instruments  be issued for cash,
property, services, or by way of dividends or otherwise.

                  7.  Voting Rights.

                  At all meetings of the stockholders of this  corporation,  the
holders of shares of Common  Stock  shall be entitled to one vote for each share
of Common Stock held by them respectively except as otherwise expressly provided
herein. The holders of shares of Preferred Stock shall have no right to vote and
shall  not be  entitled  to  notice  of any  meeting  of  stockholders  of  this
corporation nor to participate in any such meeting except as otherwise expressly
provided  herein or in any  amendment  creating a series of Preferred  Stock and
except for those  purposes,  if any,  for which said rights  cannot be denied or
waived under mandatory  provisions of law that shall be controlling.  If, and to
the extent that, the shares of any series of Preferred Stock are provided voting
rights in accordance with the provisions hereof, including the provision of such
voting  rights in any amendment  creating such series,  each holder of shares of
such  series  of  Preferred  Stock  shall  be  entitled  to one  vote  for  each
outstanding share of such series of Preferred Stock held by such holder.

                  8.  Reclassification, etc.

                  From time to time, and without  limitation of other rights and
powers of this  corporation as provided by law, this  corporation may reclassify
its capital  stock and may create or  authorize  one or more classes or kinds of
stock ranking prior to or on a parity with or subordinate to the Preferred Stock
or may increase the  authorized  amount of the Preferred  Stock or of the Common
Stock or of any other class of stock of this  corporation  or may amend,  alter,
change or repeal any of the rights,  privileges,  terms and conditions of shares
of the Preferred Stock or of any series thereof then outstanding or of shares of
the Common Stock or of any other class of stock of this  corporation,  upon such
vote,  given at a meeting  called for that  purpose,  of its  stockholders  then
entitled to vote thereon as may be provided by law; provided that the consent of
the holders of shares of the Preferred Stock (or of any series thereof) required
by the provisions of any amendment  creating any series of Preferred Stock or by




applicable  law, if any such consent be so required,  shall have been  obtained;
and provided further that the rights, privileges, terms and conditions of shares
of Common Stock shall not be subject to amendment,  alteration, change or repeal
without such vote (given by written consent,  or by vote at a meeting called for
that purpose), of the holders of Common Stock as may be provided by law.

                  9.  Consideration for Shares

                  To the extent  permitted by law, this  corporation may, at any
time,  and from time to time,  issue and  dispose of any of the  authorized  and
unissued shares of the Preferred  Stock and Common Stock for such  consideration
as may be fixed by the Board of Directors, or as may be determined in accordance
with a general  formula  established  by the Board of Directors,  or at not less
than such minimum consideration as the Board of Directors may authorize.

the number, election, term of office, filling of vacancies and other features of
such  directorships  shall  be  governed  by the  terms  and  provisions  of any
