                                   ARTICLE V.

The private  property of the  shareholders,  directors  and other  officers  and
managers of the corporation  shall in no case be liable for corporate debts, but

                                   ARTICLE VI.

SECTION 1. The  aggregate  number of shares of stock  which the  corporation  is
authorized to issue is 6,000,000  shares,  consisting of (a) 5,000,000 shares of
common stock, par value $1.00 per share (the "Common Stock"),  and (b) 1,000,000
shares of preferred  stock,  par value $1.00 per share (the "Preferred  Stock"),
issuable in one or more series.

SECTION  2. The  Board of  Directors  of the  corporation  is  hereby  expressly
authorized, at any time and from time to time, to divide the shares of Preferred
Stock  into one or more  series,  to issue from time to time in whole or in part
the shares of Preferred  Stock or the shares of any series  thereof,  and in the
resolution or resolutions  providing for the issue of shares of Preferred  Stock
or of a  particular  series to fix and  determine  the  voting  powers,  full or
limited,  or no voting powers, and such designations,  preferences and relative,
participating, optional or other special rights, and qualifications, limitations
or  restrictions  thereof  that may be  desired,  to the  fullest  extent now or
hereafter  permitted by Section 602 of Chapter 490 of Title XII of the Iowa Code
("Chapter 490"), as amended from time to time, and the other provisions of these
Articles of Incorporation;  provided,  however, that in no event shall Preferred
Stock have more than one vote per share of Preferred Stock.

SECTION  3.  Subject  to any other  provisions  of these  Amended  and  Restated
Articles of Incorporation,  holders of Common Stock shall be entitled to receive
such  dividends  and  other  distributions  in cash,  stock or  property  of the
corporation  as may be declared  thereon by the Board of Directors  from time to
time out of assets or funds of the corporation legally available therefor.

SECTION 4. No shareholder of the  corporation  shall be entitled to exercise any
right of cumulative voting.

SECTION  5. No  shareholder  of the  corporation  shall have any  preemptive  or
preferential  right,  nor be entitled as a matter of right to  subscribe  for or
purchase any part of any new or additional  issue of stock of the corporation of
any class or series,  whether issued for money or for  consideration  other than
money, or of any issue of securities convertible into stock of the corporation.

SECTION 6. The  corporation  shall be entitled to treat the person in whose name
any share of its stock is  registered  as the owner thereof for all purposes and
shall not be bound to recognize any equitable or other claim to, or interest in,
such share on the part of any other person, whether or not the corporation shall
have notice thereof, except as expressly provided by applicable law.

SECTION  7. The  corporation  shall  not issue  any  shares of Voting  Stock (as
hereinafter  defined) of the corporation or securities  convertible  into Voting
Stock of the  corporation  to persons other than Principal  Financial  Services,
Inc.  ("Principal  Financial  Services") if, as a result of such  issuance,  the
issued and  outstanding  Voting Stock of the  corporation  not held by Principal
Financial Services equals or exceeds that held by Principal  Financial Services.
For purposes of this Section 7, "Voting Stock" means  securities of any class or
any ownership  interest having voting power for the election of directors of the
corporation,  other than securities having voting power only to elect additional
directors only because of the  occurrence of a contingency.  For purposes of the
limitations set forth in this Article VI, any issued and outstanding  securities
of the corporation that are convertible into Voting Stock are considered  issued
and  outstanding  Voting  Stock of the  corporation  as though such  convertible
securities had been converted into Voting Stock in accordance with their terms.


                                  ARTICLE VII.

The  corporate  powers  of the  corporation  (except  as at the  time  otherwise
provided by law,  these Amended and Restated  Articles of  Incorporation  or the
By-Laws of the corporation) shall be exercised by the Board of Directors, and by
such  officers  and agents as the Board of  Directors  may  authorize,  elect or
appoint.  Subject  to the  rights  of any  holders  of any  class or  series  of
Preferred Stock to elect additional directors under specified circumstances, the
Board of  Directors  shall  consist  of not  less  than  nine  nor more  than 21
directors,  the number to be determined from time to time by the shareholders or
a majority of the entire Board of Directors. The Board of Directors,  other than
with respect to those  directors  who may be elected by the holders of any class
or series of Preferred  Stock,  shall be divided into three  classes,  as nearly
equal numerically as possible, determined by terms expiring in successive years.
Each  director  shall  serve a term  of  approximately  three  years  except  as
otherwise  provided or where it is  necessary  to fix a shorter term in order to
preserve classification.  The term of office of each director shall begin at the
annual  meeting at which such  director is elected or at the time elected by the
Board of  Directors.  No decrease in the number of directors  shall  shorten the
term of any incumbent  director.  Each director shall serve until a successor is
duly elected and qualified and shall be eligible for re-election. Subject to the
rights  of any  holders  of any  class or  series  of  Preferred  Stock to elect
additional directors under specified circumstances,  any vacancy or vacancies on
the  Board of  Directors  may be  filled  by the  shareholders,  by the Board of
Directors  at any  meeting  of the  Board  of  Directors  or,  if the  directors
remaining in office constitute fewer than a quorum of the Board of Directors, by
the affirmative vote of a majority of directors remaining in office. The term of
office of each  director of the  corporation  shall not extend beyond the annual
meeting of the corporation next following the date such director attains age 70,
or such  younger age as may be  established  for all  directors  by the Board of
Directors, except that the terms of directors holding office prior to the annual
meeting in 1984 may extend to the annual  meeting next  following  the date such
director  attains age 72 and except that for  officer-directors,  other than one
who is or has been  Chief  Executive  Officer  of the  corporation,  the term as
director shall not extend beyond the annual meeting next following the date such
director retires as an active officer of the  corporation.  Members of the Board
of Directors shall not be required to be policyowners of the corporation.

Subject to the rights of any holders of any class or series of  Preferred  Stock
to elect additional directors under specified circumstances, any director may be
removed,  but only for  cause,  at a meeting  of  shareholders  called  for that
purpose  in the  manner  prescribed  by law,  upon the  affirmative  vote of the
holders of a majority of the combined voting power of the then outstanding stock
of the corporation entitled to vote generally in the election of directors.

The Board of  Directors  shall have the power  without the assent or vote of the
shareholders  of the corporation to adopt such By-Laws and rules and regulations
for the  transaction of the business of the corporation  not  inconsistent  with
these Amended and Restated Articles of Incorporation or the laws of the State of
Iowa,  and to amend,  alter or repeal such By-Laws,  rules and  regulations.  In
addition to any requirements of law and any other provision of these Articles of
Incorporation,  the shareholders of the corporation may adopt,  amend,  alter or
repeal the By-Laws of the corporation  upon the  affirmative  vote of holders of
more  than 50% of the  combined  voting  power of the  outstanding  stock of the
corporation  entitled to vote  generally in the election of  directors.  Advance
notice of  nominations  for the  election  of  directors  and of  business to be
brought by  shareholders  before any meeting of  shareholders of the corporation
shall be given in the manner and to the extent  provided  in the  By-Laws of the
corporation.  The Board of  Directors  may fix  reasonable  compensation  of the
directors for their  services.  The Board of Directors  shall elect a President,
and shall authorize,  elect or appoint such other officers, agents or committees
as in their judgment may be necessary or advisable.

A director, in determining what is in the best interests of the corporation when
considering  a  proposal  of  acquisition,   merger  or   consolidation  of  the
corporation  or a similar  proposal,  may consider  any or all of the  following
community  interest factors,  in addition to consideration of the effects of any
action  on  shareholders:  (i)  the  effects  of  action  on  the  corporation's
employees, suppliers, creditors and customers; (ii) the effects of the action on
the communities in which the corporation and its subsidiaries operate; and (iii)
the  long-term  as well  as  short-term  interests  of the  corporation  and its
shareholders,  including the possibility that these interests may be best served
by the continued independence of the corporation.

If on the basis of the community  interest factors described above, the Board of
Directors of the corporation  determines that a proposal to acquire or merge the
corporation is not in the best interests of the  corporation,  it may reject the
proposal. If the Board of Directors of the corporation  determines to reject any
such proposal, the Board of Directors has no obligation to facilitate, to remove
any barriers to or to refrain from impeding the proposal.  Consideration  of any
or all of the  community  interest  factors is not a violation  of the  business
judgment rule or of any duty of the director to the shareholders,  or a group of
shareholders,  even  if the  director  reasonably  determines  that a  community
interest  factor or factors  outweigh  the  financial  or other  benefits to the
corporation or a shareholder or group of shareholders.


                                  ARTICLE VIII.

The corporation shall indemnify directors, officers, employees and agents of the
corporation  as provided in Sections 850 through 858 of Chapter 490,  subject to
such limitations as may be established by the Board of Directors.  Any repeal or
modification  of this Article VIII or of Sections 850 through 858 of Chapter 490
shall not adversely affect any right of indemnification of a director,  officer,
employee or agent of the  corporation  existing at any time prior to such repeal
or modification.


                                   ARTICLE IX.

A director of the corporation  shall not be personally liable to the corporation
or its  shareholders  for  monetary  damages for breach of  fiduciary  duty as a
director,  except  for  liability  (a) for a breach  of the  director's  duty of
loyalty to the corporation or its shareholders, (b) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of the
law, (c) for a transaction from which the director derives an improper  personal
benefit or (d) under  Section 833 of Chapter  490, as amended from time to time.
If Chapter 490 is hereafter  amended to  authorize  the further  elimination  or
limitation of the  liability of  directors,  then the liability of a director of
the corporation,  in addition to the limitation on personal  liability  provided
herein,  shall  be  eliminated  or  limited  to the  extent  of such  amendment,
automatically and without any further action, to the maximum extent permitted by
law.  Any repeal or  modification  of the  provisions  of this Article IX by the
shareholders  of the  corporation  shall  be  prospective  only  and  shall  not
adversely affect any limitation in the personal  liability or any other right or
protection of a director of the  corporation  with respect to any state of facts
existing at or prior to the time of such repeal or modification.

                                   ARTICLE X.

Effective  as of such time as the Common Stock shall be  registered  pursuant to
the  provisions of the Securities  Exchange Act of 1934, as amended,  any action
required or permitted to be taken by the shareholders of the corporation must be
effected at a duly called annual or special  meeting of the  shareholders of the
corporation,  and the ability of the  shareholders  to consent in writing to the
taking of any action is specifically denied.

                                   ARTICLE XI.

Amendments to these Articles of Incorporation are subject to the approval of the
Iowa Insurance Commissioner and the Iowa Attorney General as provided in Section
508.4 of Title XIII of the Iowa Code.
