          Section 2.01.  PLACE AND TIME OF MEETINGS. Except as provided
otherwise by Minnesota Statutes Chapter 302A, meetings of the shareholders may

          Section 2.03.  SPECIAL MEETINGS. Special meetings of the shareholders
may be held at any time and for any purpose and may be called by the President,
Treasurer, any two or more directors, or by one or more shareholders holding 10%
or more of the shares entitled to vote on the matters to be presented to the
meeting.

          Section 2.04.  QUORUM, ADJOURNED MEETINGS. The holders of a majority
of the shares entitled to vote shall constitute a quorum for the transaction of
business at any regular or special meeting. In case a quorum shall not be

shall, by majority vote, agree upon, and a notice of such adjournment and the
date and time at which such meeting shall be reconvened shall be mailed to each
shareholder entitled to vote at least 5 days before such reconvened meeting. If
a quorum is present, a meeting may be adjourned from time to time without notice
other than announcement at the meeting. At adjourned meetings at which a quorum
is present, any business may be transacted which might have been transacted at

shareholder having the right to vote shall be entitled to vote either in person
or by proxy. Each shareholder, unless the Articles of Incorporation or statute
provide otherwise, shall have one vote for each share having voting power

owned shares may be voted by any joint owner unless the corporation receives
written notice from any one of them denying the authority of that person to vote
those shares. Upon the demand of any shareholder, the vote upon any question
before the meeting shall be by ballot. All questions shall be decided by a
majority vote of the number of shares entitled to vote and represented at the
meeting at the time of the vote except if otherwise required by statute, the
Articles of Incorporation, or these Bylaws.

          Section 2.06.  CLOSING OF BOOKS. The Board of Directors may fix a
time, not exceeding 60 days preceding the date of any meeting of shareholders,
as a record date for the determination of the shareholders entitled to notice
of, and to vote at, such meeting, notwithstanding any transfer of shares on the
books of the corporation after any record date so fixed. The Board of Directors
may close the books of the corporation against the transfer of shares during the
whole or any part of such period. If the Board of Directors fails to fix a
record date for determination of the shareholders entitled to notice of, and to
vote at, any meeting of shareholders, the record date shall be the 20th day
preceding the date of such meeting.

          Section 2.07.  NOTICE OF MEETINGS. There shall be mailed to each
shareholder, shown by the books of the corporation to be a holder of

                                       -2-
<Page>

record of voting shares, at his address as shown by the books of the
corporation, a notice setting out the time and place of each regular meeting and
each special meeting, except where the meeting is an adjourned meeting and the
date, time and place of the meeting were announced at the time of adjournment,
which notice shall be mailed at least five days prior thereto; except that
notice of a meeting at which an agreement of merger or exchange is to be
considered shall be mailed to all shareholders of record, whether entitled to
vote or not, at least fourteen days prior thereto. Every notice of any special
meeting called pursuant to Section 2.03 hereof shall state the purpose or
purposes for which the meeting has been called, and the business transacted at
all special meetings shall be confined to the purpose stated in the notice.

          Section 2.08.  WAIVER OF NOTICE. Notice of any regular or special
meeting may be waived by any shareholder either before, at or after such meeting
orally or in writing signed by such shareholder or a representative entitled to
vote the shares of such shareholder. A shareholder, by his attendance at any
meeting of shareholders, shall be deemed to have waived notice of such meeting,
except where the shareholder objects at the beginning of the meeting to the
transaction of business because the item may not lawfully be considered at that
meeting and does not participate in the consideration of the item at that
meeting.

          Section 2.09.  WRITTEN ACTION. Any action which might be taken at a
meeting of the shareholders may be taken without a meeting if done in writing
and signed by all of the shareholders entitled to vote on that action.

          Section 3.01.  GENERAL POWERS. The business and affairs of the
corporation shall be managed by or under the authority of the Board of
Directors, except as otherwise permitted by statute.

          Section 3.02.  NUMBER, QUALIFICATION AND TERM OF OFFICE. Until the
first meeting of shareholders, the number of directors shall be the number named
in the Articles of Incorporation or, if no such number is named therein, the
number elected by the incorporator. Thereafter, the number of directors shall be
established by resolution of the shareholders (subject to the authority of the
Board of Directors to increase or decrease the number of directors as permitted
by law). In the absence of such shareholder resolution, the number of directors
shall be the number last fixed by the shareholders, the Board of Directors, the
incorporator or the Articles of Incorporation. Directors need not be
shareholders. Each of the directors shall hold office until the regular meeting
of shareholders next held after such director's election and until such
director's successor shall have been elected and shall qualify, or until the
earlier death, resignation, removal, or disqualification of such director,
provided; however, that no director shall be elected to a term in excess of
five years.

          Section 3.05.  WAIVER OF NOTICE. Notice of any meeting of the Board of
Directors may be waived by any director either before, at, or after such meeting
orally or in a writing signed by such director. A director, by his attendance at
any meeting of the Board of Directors, shall be deemed to have waived notice of
such meeting, except where the director objects at the beginning of the meeting
to the transaction of business because the meeting is not lawfully called or
convened and does not participate thereafter in the meeting.

          Section 3.06.  QUORUM. A majority of the directors holding office
immediately prior to a meeting of the Board of Directors shall constitute a
quorum for the transaction of business at such meeting.

          Section 3.07.  ABSENT DIRECTORS. A director may give advance written
consent or opposition to a proposal to be acted on at a meeting of the Board of
Directors. If such director is not present at the meeting, consent or opposition
to a proposal does not constitute presence for purposes of determining the
existence of a quorum, but consent or opposition shall be counted as a vote in
favor of or against the proposal and shall be entered in the minutes or other
record of action at the meeting, if the proposal acted on at the meeting is
substantially the same or has substantially the same effect as the proposal to
which the director has consented or objected.

          Section 3.08.  CONFERENCE COMMUNICATIONS. Any or all directors may
participate in any meeting of the Board of Directors, or of any duly constituted
committee thereof, by any means of communication through which the directors may
simultaneously hear each other during such meeting. For the purposes of
establishing a quorum and taking any action at the meeting, such directors
participating pursuant to this Section 3.08 shall be deemed present in person at
the meeting; and the place of the meeting shall be the place of origination of
the conference telephone conversation or other comparable communication
technique.

          Section 3.09.  VACANCIES; NEWLY CREATED DIRECTORSHIPS. Vacancies in
the Board of Directors of this corporation occurring by reason of death, or
resignation, removal or disqualification shall be filled for the unexpired term
by a majority of the remaining directors of the Board although less than a
quorum; newly created directorships

                                       -4-
<Page>

resulting from an increase in the authorized number of directors by action of
the Board of Directors as permitted by Section 3.02 may be filled by a majority
vote of the directors serving at the time of such increase; and each director
elected pursuant to this Section 3.09 shall be a director until such director's
successor is elected by the shareholders at their next regular or special
meeting.

          Section 3.10.  REMOVAL. Any or all of the directors may be removed
from office at any time, with or without cause, by the affirmative vote of the
shareholders holding a majority of the shares entitled to vote at an election of
directors except, as otherwise provided by Minnesota Statutes Section 302A.223,
as amended, when the shareholders have the right to cumulate their votes. A
director named by the board of Directors to fill a vacancy may be removed from
office at any time, with or without cause, by the affirmative vote of the
remaining directors if the shareholders have not elected directors in the
interim between the time of the appointment to fill such vacancy and the time of
the removal. In the event that the entire Board or any one or more directors be
so removed, new directors shall elected at the same meeting.

          Section 3.11.  COMMITTEES. A resolution approved by the affirmative
vote of a majority of the Board of Directors may establish committees having the
authority of the board in the management of the business of the corporation to
the extent provided in the resolution. A committee shall consist of one or more
persons, who need not be directors, appointed by affirmative vote of a majority
of the directors present. Committees are subject to the direction and control
of, and vacancies in the membership thereof shall be filled by, the Board of
Directors, except as provided by Minnesota Statutes Section 302A.243.

          A majority of the members of the committee present at a meeting is a
quorum for the transaction of business, unless a larger or smaller proportion or
number is provided in a resolution approved by the affirmative vote of a
majority of the directors present.

          Section 3.12.  WRITTEN ACTION. Any action which might be taken at a
meeting of the Board of Directors, or any duly constituted committee thereof,
may be taken without a meeting if done in writing and signed by all of the
directors or committee members, unless the Articles provide otherwise and the
action need not be approved by the shareholders.

          Section 3.13.  COMPENSATION. Directors who are not salaried officers
of this corporation shall receive such fixed sum per meeting attended or such
fixed annual sum as shall be determined, from time to time, by resolution of the
Board of Directors. The Board of Directors may, by resolution, provide that all
directors shall receive their expenses, if any, of attendance at meetings of the
Board of Directors or any committee thereof. Nothing herein contained shall be
construed to preclude any director from serving this corporation in any other
capacity and receiving proper compensation therefor.

                                  ARTICLE XII.
                      RESTRICTIONS UPON TRANSFER OF SHARES

          Section 12.01. Each holder of a common share or shares (hereinafter
referred to as "shares") of the corporation, upon acquiring the same in any
manner, thereby and hereby gives and grants, upon the terms and conditions
herein stated, to the corporation and to its shareholders an irrevocable right
and option to purchase the share or shares so acquired by such holder.

          Section 12.02. Such irrevocable right and option shall be exercisable
as hereinafter provided upon the occurrence of any one or more of the following
events (hereinafter referred to as "Purchase Events"):

          A. the death of any shareholder, except as provided below;

          B. the appointment by a court of competent jurisdiction or otherwise
of a receiver, a trustee, or assignee of any shareholder of his property;

          C. the voluntary application of any shareholder for relief under any
act of congress or any of the laws of the several states, now or hereinafter
enacted, providing for the relief of debtors;

          D. the expiration of thirty (30) days immediately following the date
upon which a judgment entered in a court of record against any shareholder
becomes final, provided such judgment remains unsatisfied;

          E. the institution of a levy, garnishment of attachment involving the
shares of any shareholder;

          F. the expressed desire of any shareholder to sell, assign, pledge,
transfer, or otherwise dispose of or encumber any share or shares of the
corporation owned by him.

               Any shareholder may, notwithstanding the provisions of Section
12.02, transfer or dispose of his shares by testamentary disposition, or by
virtue of the laws of descent in case of intestacy to his or her spouse, or to a
trustee for the benefit of his or her spouse, without giving rise to the
foregoing purchase option; but the shares so transferred shall continue, in the
hands of such beneficiary or distributee, to be subject to the provisions of
this Article XII as to any supervening transaction, with the same effect as if
such shares were still owned and held by the decedent. However, if by bequest or
distribution, any shares pass or are ordered or decreed by any Court of Probate
jurisdiction to anyone except the shareholder's spouse, the corporation and its
shareholders shall have the right and option to purchase the same for a sum
equal to the value of such shares as calculated according to Section 12.03(F).

                                      -12-
<Page>

          Section 12.03. Such irrevocable right and option shall be exercisable
upon the occurrence of any one or more Purchase Events in the following manner
and upon the following terms (provided that nothing herein shall prohibit the
exercise of this option where a Purchase Event has occurred but no notice of a
Purchase Event has been served as provided below):

               A. Upon the happening of any Purchase Event and before any sale,
assignment, pledge, transfer or other disposition or encumbrance of any share or
shares of the corporation may be made, written notice of the occurrence of said
Purchase Event shall be given by or on behalf of the holder or holders of said
share or shares by registered mail to the corporation at its then principal
place of business, which notice shall specify the number of shares affected by
the Purchase Event, the certificate or certificates evidencing the same and the
Purchase Event.

               B. The corporation shall have, within the thirty (30) days next
following the receipt by it of such notice of Purchase Event (hereinafter
referred to as the "First Purchase Period"), an option to purchase all or any
part of the share or shares referred to in said notice from the holder or
holders thereof at the price per share and upon the terms hereinafter stated.

               C. If the corporation fails to exercise its option with respect
to any or all of the shares referred to in said notice of Purchase Event, each
of the shareholders of the corporation, except the shareholder giving said
notice, shall have the option to purchase, at the price per share and upon the
terms and conditions hereinafter stated, his pro rata share of the shares
specified in said notice which the corporation does not purchase (calculated to
the nearest full share), which option shall continue for a period of thirty (30)
days next following the expiration of the First Purchase Period (hereinafter
referred to as the ("Second Purchase Period"). The Board of Directors shall
calculate the number of shares (to the nearest full share) which each of the
shareholders shall be entitled to purchase and the purchase price per
share as hereinafter determined, and shall give written notice on or before the
expiration of said First Purchase Period to each of the shareholders of the
corporation at his address, as the same then appears on the books and records of
the corporation, setting forth: (a) that a notice of Purchase Event has been
received from a shareholder, naming him; (b) the number of shares referred to
in such notice of Purchase Event; (c) the number of shares, if any, to be
purchased by the corporation from said shareholder as a result of such notice of
Purchase Event; (d) the number of shares which each shareholder shall be
entitled to purchase pursuant to this option; (e) the purchase price per share;
and (f) the date on which the option to purchase such shares must be exercised,
which date shall be five (5) days prior to the expiration of said Second
Purchase Period. On or before the date specified in such notice to shareholders
as the expiration date for the exercise of their option to purchase such shares,
each shareholder desiring to purchase any

                                      -13-
<Page>

such shares, shall give written notice thereof by registered mail to the
corporation at its then principal place of business specifying the number of
shares which the shareholder is willing to purchase, which number may be the
same as or more or less than the number of shares which is offered to such
shareholder pursuant to said notice. The difference between the number of shares
offered each shareholder and the number which he has given notice that he
desires to purchase shall be referred to as "under-subscribed shares" or
"over-subscribed shares" as the case may be. Under-Subscribed shares shall be
allotted among those shareholders who give notice of a desire to purchase
under-subscribed shares in an amount equal to the proportion which the
over-subscription of each over-subscribing shareholders bears to the total
subscriptions.

               D. Not less than five (5) days prior to the expiration of said
Second Purchase Period, each shareholder who desires to exercise this option
shall deliver to the corporation the purchase price, determined as hereinafter
provided with respect to the share or shares allotted to him pursuant to this
option. The sum so received shall be held by the corporation in trust to be paid
to the shareholder giving such notice of Purchase Event, or his legal
representative, upon receipt of a certificate or certificates, duly endorsed in
blank and with signature duly guaranteed.

               E. On or before the date for exercise of this option, the
corporation shall notify the shareholder or person who gave such notice of
Purchase Event at his address, as the same then appears upon the books and
records of the corporation, that this option has been exercised, and the name
and address of the person or persons exercising the same. Within twenty-four
(24) hours of the receipt thereof, the holder of said shares or his legal
representative shall deliver the certificate of certificates evidencing the same
to the corporation at its then principal place of business, duly endorsed in
blank and with signature duly guaranteed, upon delivery to said holder or his
legal representative of the purchase price, determined as hereinafter provided,
for the shares so delivered.

               F. The amount to be paid per share for any and all shares
purchased pursuant to this option, shall be the book value per share, at the
close of the most recent month preceding the occurence of the Purchase Event,
as determined by any independent certified public accountant, who may be the one
who regularly examines the financial statements of the corporation, selected by
the Board of Directors; provided, however, that if the corporation shall have
had made by an independent appraiser selected by the accountant an appraisal of
any of its physical assets and such appraisal shall have been accepted by the
Board of Directors of the corporation as fairly representing the value of such
assets, the value of the physical assets covered by such appraisal shall be not
the book value thereof but rather the value thereof set forth in such appraisal.

                                      -14-

               G. The purchase price shall be paid by each purchaser issuing a
down payment of one-fifth (1/5th) of that portion of the purchase price for
which he is responsible and by giving a note for the balance payable to the
seller in four (4) equal annual installments without interest, the first of
which shall be due one (1) year after the down payment was made.

               H. Nothing contained herein shall be construed to obligate this
corporation to pay to the shareholder giving such notice of Purchase Event, or
any one claiming under or through him, any part of the purchase price payable by
a shareholder exercising this option except to the extent that the same is
received from such a shareholder.

               I. In the event the corporation and the shareholders of the
corporation do not purchase all of the shares covered by a notice of Purchase
Event, the person giving the same may sell, assign, transfer, pledge, or
otherwise dispose of the balance of such shares, free and clear of the terms and
conditions hereof at any time within sixty (60) days following the expiration of
the Second Purchase Period, but each person acquiring any of such shares shall
acquire the same subject to all the terms and conditions of this Article XII.
After the expiration of such sixty (60) day period, any shares not disposed of
by the person giving such notice of Purchase Event shall again become subject to
all the terms and conditions of this Article XII.

          Section 12.04. No sale, assignment, pledge, transfer, or other
disposition or encumbrance of any shares of the corporation, whether voluntary
or involuntary, by operation of law or otherwise, shall be valid for any purpose
whatsoever without first complying with the terms and conditions of this Bylaw,
and any attempt thereat shall be null and void. Any and all claims, liens or
interests, now or hereafter secured or imposed by legal action or otherwise, in,
to, or upon the shares of the corporation by any creditor or creditors of the
holder thereof shall be subject to and limited by all of the terms and
conditions hereof.

          Section 12.05. Each certificate representing a share or shares of the
corporation shall contain on the face thereof the following notice:

               "Any sale, assignment, transfer, pledge, or other disposition of
the shares evidenced by this certificate, whether voluntary or involuntary, is
subject to restrictions by virtue of any option to purchase said shares vested
in the corporation and in the holders of its shares, all as set forth in the
Bylaws of the corporation and to all of which the holder by acceptance hereof
assents."
