                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS
                            ------------------------

     Section 1. All meetings of the stockholders shall be held at any place
within or outside the State of Iowa as shall be designated from time to time by
the Board of Directors. In the absence of any such designation, stockholders
meetings shall be held at the principal executive office of the Corporation.

     Section 2. The annual meeting of stockholders shall be held on such date
and at such time and place as may be fixed by the Board of Directors and stated
in the notice of the meeting, for the purpose of electing directors and for the
transaction of such other business as is properly brought before the meeting in
accordance with these By-Laws.

     To be properly brought before the annual meeting, business must be either
(i) specified in the notice of annual meeting (or any supplement or amendment
thereto) given



by or at the direction of the Board of Directors, (ii) otherwise brought before
the annual meeting by or at the direction of the Board of Directors, or (iii)
otherwise properly brought before the annual meeting by a stockholder. In
addition to any other applicable requirements, for business to be properly
brought before an annual meeting by a stockholder, the stockholder must have
given timely notice thereof in writing to the Secretary of the Corporation. To
be timely, a stockholder's notice must be delivered to or mailed and received at
the principal executive offices of the Corporation, not less than fifty (50)
days nor more than seventy-five (75) days prior to the meeting; provided,
however, that in the event that less than sixty-five (65) days notice or prior
public disclosure of the date of the annual meeting is given or made to
stockholders, notice by a stockholder to be timely must be so received not later
than the close of business on the fifteenth (15th) day following the day on
which such notice of the date of the annual meeting was mailed or such public
disclosure was made, whichever first occurs. A stockholder's notice to the
Secretary shall set forth (a) as to each matter the stockholder proposes to
bring before the annual meeting (i) a brief description of the business desired
to be brought before the annual meeting and the reasons for conducting such
business at the annual meeting, (ii) the name and record address of the
stockholder proposing such business, (iii) the class, series and number of
shares of the Corporation which are beneficially owned by the stockholder, and
(iv) any material interest of the stockholder in such business and (b) as to the
stockholder giving the notice (i) the name and record address of the stockholder
and (ii) the class and number of shares of capital stock of the Corporation
which are beneficially owned by the stockholder. Notwithstanding anything in the
By-Laws to the contrary, no

                                      -2-



business shall be conducted at the annual meeting except in accordance with the
procedures set forth in this Article II, Section 2. The officer of the
Corporation presiding at an annual meeting shall, if the facts warrant,
determine and declare to the annual meeting that business was not properly
brought before the annual meeting in accordance with the provisions of this
Article 11, Section 2, and if he should so determine, he shall so declare to the
annual meeting and any such business not properly brought before the meeting
shall not be transacted. Written notice of the annual meeting stating the place,
date and hour of the annual meeting shall be given to each stockholder entitled
to vote at such meeting not less than ten (10) nor more than sixty (60) days
before the date of the meeting.

     Section 3. A majority of the stock issued and outstanding and entitled to
vote at any meeting of stockholders, the holders of which are present in person
or represented by proxy, shall constitute a quorum for the transaction of
business except as otherwise provided by law, by the Articles of Incorporation,
or by these By-Laws. A quorum, once established, shall not be broken by the
withdrawal of enough votes to leave less than a quorum and the votes present may
continue to transact business until adjournment. If, however, such quorum shall
not be present or represented at any meeting of the stockholders, a majority of
the voting stock represented in person or by proxy may adjourn the meeting from
time to time, without notice other than announcement at the meeting, until a
quorum shall be present or represented. At such adjourned meeting at which a
quorum shall be present or represented, any business may be transacted which
might have been transacted at the meeting as originally notified. If the
adjournment is for more than thirty

                                      -3-



days, or if after the adjournment a new record date is fixed for the adjourned
meeting, a notice of the adjourned meeting shall be given to each stockholder of
record entitled to vote thereat.

     Section 4. When a quorum is present at any meeting, the vote of the holders
of a majority of the stock having voting power present in person or represented
by proxy shall decide any question brought before such meeting, unless the
question is one upon which by express provision of the statutes, or the Articles
of Incorporation, or these By-Laws, a different vote is required in which case
such express provision shall govern and control the decision of such question.

     Section 5. At each meeting of the stockholders, each stockholder having the
right to vote may vote in person or may authorize another person or persons to
act for him by proxy appointed by an instrument in writing subscribed by such
stockholder and bearing a date not more than three years prior to said meeting,
unless said instrument provides for a longer period. All proxies must be filed
with the Secretary of the Corporation at the beginning of each meeting in order
to be counted in any vote at the meeting. Each stockholder shall have one vote
for each share of stock having voting power, registered in his name on the books
of the Corporation on the record date set by the Board of Directors as provided
in Article V, Section 6 hereof. All elections shall be had and all questions
decided by a plurality vote.

     Section 6. Special meetings of the stockholders, for any purpose, or
purposes, unless otherwise prescribed by statute or by the Articles of
Incorporation, may be called by the President and shall be called by the
President or the Secretary at the request in

                                      -4-



writing of a majority of the Board of Directors, or at the request in writing of
stockholders owning a majority in amount of the entire capital stock of the
Corporation issued and outstanding, and entitled to vote. Such request shall
state the purpose or purposes of the proposed meeting. Business transacted at
any special meeting of stockholders shall be limited to the purposes stated in
the notice.

     Section 7. Whenever stockholders are required or permitted to take any
action at a meeting, a written notice of the meeting shall be given which notice
shall state the place, date and hour of the meeting, and, in the case of a
special meeting, the purpose or purposes for which the meeting is called. The
written notice of any meeting shall be given to each stockholder entitled to
vote at such meeting not less than ten nor more than sixty days before the date
of the meeting. If mailed, notice is given when deposited in the United States
mail, postage prepaid, directed to the stockholder at his address as it appears
on the records of the Corporation.

     Section 8. The officer who has charge of the stock ledger of the
Corporation shall prepare and make, at least ten days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the

                                      -5-



time and place of the meeting during the whole time thereof, and may be
inspected by any stockholder who is present.

     Section 9. Unless otherwise provided in the Articles of Incorporation, any
action required to be taken at any annual or special meeting of stockholders of
the Corporation, or any action which may be taken at any annual or special
meeting of such stockholders, may be taken without a meeting, without prior
notice and without a vote, only if a consent in writing, setting forth the
action so taken, shall be signed by the holders of all of the outstanding stock
having the right to vote to authorize or take such action.

                                  ARTICLE III

                                   DIRECTORS
                                   ---------

     Section 1. The number of directors which shall constitute the whole Board
shall be not less than 2 nor more than 10. The directors need not be
stockholders. Only persons who are nominated in accordance with the following
procedures shall be eligible for election as directors. Nominations of persons
for election to the Board of Directors of the Corporation at the annual meeting
may be made at such meeting by or at the direction of the Board of Directors, by
any committee or persons appointed by the Board of Directors or by any
stockholder of the Corporation entitled to vote for the election of directors at
the meeting who complies with the notice procedures set forth in this Article
III, Section 1. Such nominations by any stockholder shall be made pursuant to
timely notice in writing to the Secretary of the Corporation. To be timely, a
stockholder's notice shall be delivered to or mailed and received at the
principal executive offices of the Corporation not less than 50 days nor more
than 75 days prior to the meeting; provided, however, that in the event

                                      -6-



that less than 65 days notice or prior public disclosure of the date of the
meeting is given or made to stockholders, notice by the stockholder to be timely
must be so received not later than the close of business of the fifteenth (15th)
day following the day on which such notice of the date of the meeting was mailed
or such public disclosure was made, whichever first occurs. Such stockholder's
notice to the Secretary shall set forth (i) as to each person whom the
stockholder proposes to nominate for election or reelection as a director, (a)
the name, age, business address and residence address of the person, (b) the
principal occupation or employment of the person, (c) the class and number of
shares of capital stock of the Corporation which are beneficially owned by the
person, and (d) any other information relating to the person that is required to
be disclosed in solicitations for proxies for election of directors pursuant to
the Rules and Regulations of the Securities and Exchange Commission under
Section 14 of the Securities Exchange Act of 1934, as amended; and (ii) as to
the stockholder giving the notice (a) the name and record address of the
stockholder and (b) the class and number of shares of capital stock of the
Corporation which are beneficially owned by the stockholder. The Corporation may
require any proposed nominee to furnish such other information as may reasonably
be required by the Corporation to determine the eligibility of such proposed
nominee to serve as a director of the Corporation. No person shall be eligible
for election as a director of the Corporation unless nominated in accordance
with the procedures set forth herein. The officer of the Corporation presiding
at an annual meeting shall, if the facts warrant, determine and declare to the
meeting that a nomination was not made, in accordance with the foregoing
procedure, and if he should so determine, he shall so declare to the meeting

                                      -7-



and the defective nomination shall be disregarded. The directors shall be
elected at the annual meeting of the stockholders, except as provided in Section
2 of this Article III, and each director elected shall hold office until his
successor is elected and qualified; provided, however, that unless otherwise
restricted by the Articles of Incorporation or law, any director or the entire
Board of Directors may be removed, either with or without cause, from the Board
of Directors at any meeting of stockholders by a majority of the stock
represented and entitled to vote thereat.

     Section 2. Vacancies on the Board of Directors by reason of death,
resignation, retirement, disqualification, removal from office, or otherwise,
and newly created directorships resulting from any increase in the authorized
number of directors may be filled by a majority of the directors then in office,
although less than a quorum. The directors so chosen shall hold office until the
next annual election of directors and until their successors are duly elected
and shall qualify, unless sooner displaced. If there are no directors in office,
then an election of directors may be held in the manner provided by statute.

     Section 3. The property and business of the Corporation shall be managed by
or under the direction of its Board of Directors. In addition to the powers and
authorities by these By-Laws expressly conferred upon them, the Board may
exercise all such powers of the Corporation and do all such lawful acts and
things as are not by statute or by the Articles of Incorporation or by these
By-Laws directed or required to be exercised or done by the stockholders.

                                      -8-



                       MEETINGS OF THE BOARD OF DIRECTORS

     Section 4. The directors may hold their meetings and have one or more
offices, and keep the books of the Corporation outside of the State of Iowa.

     Section 5. Regular meetings of the Board of Directors may be held without
notice at such time and place as shall from time to time be determined by the
Board.

     Section 6. Special meetings of the Board of Directors may be called by the
President on twenty-four hours notice to each director, either personally or by
mail or by telegram; special meetings shall be called by the President or the
Secretary in like manner and on like notice on the written request of two
directors unless the Board consists of only one director; in which case special
meetings shall be called by the President or Secretary in like manner or on like
notice on the written request of the sole director.

     Section 7. At all meetings of the Board of Directors a majority of the
authorized number of directors shall be necessary and sufficient to constitute a
quorum for the transaction of business, and the vote of a majority of the
directors present at any meeting at which there is a quorum, shall be the act of
the Board of Directors, except as may be otherwise specifically provided by
statute, by the Articles of Incorporation or by these By-Laws. If a quorum shall
not be present at any meeting of the Board of Directors the directors present
thereat may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present.

     Section 8. Unless otherwise restricted by the Articles of Incorporation or
these By-Laws, any action required or permitted to be taken at any meeting of
the Board of Directors or of any committee thereof may be taken without a
meeting, if all members of the Board

                                      -9-



or committee, as the case may be, consent thereto in writing, and the writing or
writings are filed with the minutes of proceedings of the Board or committee.

     Section 9. Unless otherwise restricted by the Articles of Incorporation or
these By-Laws, members of the Board of Directors, or any committee designated by
the Board of Directors, may participate in a meeting of the Board of Directors,
or any committee, by means of conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
each other, and such participation in a meeting shall constitute presence in
person at such meeting.

                             COMMITTEES OF DIRECTORS
                             -----------------------

     Section 10. The Board of Directors may, by resolution passed by a majority
of the whole Board, designate one or more committees, each such committee to
consist of one or more of the directors of the Corporation. The Board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee. In
the absence or disqualification of a member of a committee, the member or
members thereof present at any meeting and not disqualified from voting, whether
or not he or they constitute a quorum, may unanimously appoint another member of
the Board of Directors to act at the meeting in the place of any such absent or
disqualified member. Any such committee, to the extent provided in the
resolution of the Board of Directors, shall have and may exercise all the powers
and authority of the Board of Directors in the management of the business and
affairs of the Corporation, but no such committee shall have the power or
authority in reference to amending the Articles of Incorporation (except that a
committee may, to the

                                      -10-



extent authorized in the resolution or resolutions providing for the issuance of
shares of stock adopted by the board of directors, fix the designations and any
of the preferences or rights of such shares relating to dividends, redemption,
dissolution, any distribution of assets of the Corporation or the conversion
into, or the exchange of such shares for, shares of any other class or classes
or any other series of the same or any other class or classes of stock of the
Corporation or fix the number of shares of any series of stock or authorize the
increase or decrease of the shares of any series), adopting an agreement of
merger or consolidation, recommending to the stockholders the sale, lease or
exchange of all or substantially all of the Corporation's property and assets,
recommending to the stockholders a dissolution of the Corporation or a
revocation of a dissolution, or amending the By-Laws of the Corporation; and,
unless the resolution, By-Laws, or the Articles of Incorporation expressly so
provide, no such committee shall have the power or authority to declare a
dividend, to authorize the issuance of stock, or to adopt Articles of Merger.

     Section 11. Each committee shall keep regular minutes of its meetings and
report the same to the Board of Directors when required.

                           COMPENSATION OF DIRECTORS
                           -------------------------

     Section 12. Unless otherwise restricted by the Articles of Incorporation or
these By-Laws, the Board of Directors shall have the authority to fix the
compensation of directors. The directors may be paid their expenses, if any, of
attendance at each meeting of the Board of Directors and may be paid a fixed sum
for attendance at each meeting of the Board of Directors or a stated salary as
director. No such payment shall preclude any director from serving the
Corporation in any other capacity and receiving compensation

                                      -11-



therefor. Members of special or standing committees may be allowed like
compensation for attending committee meetings.

                                 INDEMNIFICATION
                                 ---------------

     Section 13.(a) To the full extent authorized by law, the Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or in
the right of the Corporation) by reason of the fact that he is or was a
director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys, fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contenders or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

     (b) To the full extent authorized by law, the Corporation shall indemnify
any person who was or is a party or is threatened to be made a party to any
threatened,

                                      -12-



pending or completed action or suit by or in the right of the Corporation to
procure a judgment in its favor by reason of the fact that he is or was a
director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection with the defense or settlement of such action or suit if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Corporation and except that no such
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the District Court of Iowa or the court in
which such action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, such person is fairly and reasonably entitled to indemnity for such
expenses which such district court or such other court shall deem proper.

     (c) To the extent that a director, officer, employee or agent of the
Corporation shall be successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in paragraphs (a) and (b), or in defense
of any claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith to the full extent authorized by law.

     (d) Any indemnification under paragraphs (a) and (b) (unless ordered by a
court) shall be made by the Corporation only as authorized in the specific case
upon a determination that indemnification of the director, officer, employee or
agent is proper in

                                      -13-



the circumstances because he has met the applicable standard of conduct set
forth in paragraphs (a) and (b). Such determination shall be made (1) by the
Board of Directors by a majority vote of a quorum consisting of directors who
were not parties to such action, suit or proceeding, or (2) if such a quorum is
not obtainable, or, even if obtainable a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (3) by the
stockholders.

     (e) Expenses incurred by an officer or director in defending a civil or
criminal action, suit or proceeding may be paid by the Corporation in advance of
the final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the Corporation as authorized in this Section 13. Such expenses incurred by
other employees and agents may be so paid upon such terms and conditions, if
any, as the Board of Directors deems appropriate.

     (f) The indemnification and advancement of expenses provided by, or granted
pursuant to, the other paragraphs of this Section 13 shall not be deemed
exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any By-Law, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office. If a claim for indemnification or payment of expenses under this Section
13 is not paid in full within ninety (90) days after a written claim therefor
has been received by the Corporation, the claimant may file suit to recover the
unpaid amount of such claim and, if successful in whole or in part, shall be
entitled to be paid the expense

                                      -14-



of prosecuting such claim. In any such action the Corporation shall have the
burden of proving that the claimant was not entitled to the requested
indemnification or payment of expenses under applicable law.

     (g) The Board of Directors may authorize, by a vote of a majority of a
quorum of the Board of Directors, the Corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the Corporation would have the power to indemnify him
against such liability under the provisions of this Section 13.

     (h) The Board of Directors may authorize the Corporation to enter into a
contract with any person who is or was a director, officer, employee or agent of
the Corporation or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another partnership, joint venture,
trust or other enterprise providing for indemnification rights equivalent to or,
if the Board of Directors so determines, greater than those provided for in this
Section 13.

     (i) For the purposes of this Section 13, references to "the Corporation"
shall include, in addition to the resulting Corporation, any constituent
Corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, and employees
or agents, so that any person who is or was a director, officer,

                                      -15-



employee or agent of such constituent Corporation, or is or was serving at the
request of such constituent Corporation as a director, officer, employee or
agent of another Corporation, partnership, joint venture, trust or other
enterprise shall stand in the same position under the provisions of this Section
with respect to the resulting or surviving Corporation as he would have with
respect to such constituent Corporation if its separate existence had continued.

     (j) for purposes of this section, references to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the Corporation" shall include service
as a director, officer, employee or agent of the Corporation which imposes
duties on, or involves services by, such director, officer, employee or agent
with respect to an employee benefit plan, its participants or beneficiaries; and
a person who acted in good faith and in a manner he reasonably believed to be in
the interest of the participants and beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best interests of
the Corporation" as referred to in this section.

     (k) The indemnification and advancement of expenses provided by, or granted
pursuant to, this Section 13 shall, unless otherwise provided when authorized or
ratified, continue as to a person who has ceased to be a director, officer,
employee or agent and shall inure to the benefit of the heirs, executors and
administrators of such a person.

                                      -16-

Directors and shall include a President, a Secretary and a Treasurer. The
Corporation may also have at the discretion of the Board of Directors such other
officers as are desired, including one or more Vice Presidents, one or more
Assistant Secretaries and Assistant Treasurers, and such other officers as may

title. At the time of the election of officers, directors may by resolution
determine the order of their rank. Any number of offices may be held by the same
person, unless the Articles of Incorporation or these By-Laws otherwise provide.
