                  its direct or indirect acquisition of beneficial ownership of
                  shares of such class or series of Capital Stock. If the
                  consideration so paid for shares of any class or series of
                  Capital Stock varied as to form, the form of consideration for
                  such class or series of Capital Stock shall be either cash or

                  appropriate adjustment in the event of any stock dividend,
                  stock split, combination of shares or similar event.

                           d. After such Interested Shareholder has become an
                  Interested Shareholder and prior to the consummation of such
                  Business Combination: (i) there shall have been no failure to
                  declare and pay at the regular date therefor any full
                  quarterly dividends (whether or not cumulative) payable in
                  accordance with the terms of any outstanding Capital Stock,
                  except as approved by a majority of the Continuing Directors;
                  (ii) there shall have been no reduction in the annual rate of
                  dividends paid on the Common Stock (except as necessary to

                  or similar event), except as approved by a majority of the
                  Continuing Directors; (iii) there shall have been an increase
                  in the annual rate of dividends paid on the Common Stock as
                  necessary to reflect any reclassification (including any
                  reverse stock split), recapitalization, reorganization or any
                  similar transaction that has the effect of reducing the number
                  of outstanding shares of Common Stock, unless the failure to
                  increase such annual rate is approved by a majority of the
                  Continuing Directors; and (iv) except as approved by a
                  majority of the Continuing Directors, such Interested
                  Shareholder shall not have become the beneficial owner of any
                  additional shares of Capital Stock except as part of the
                  transaction that results in such Interested Shareholder
                  becoming an Interested Shareholder and except in a transaction
                  that, after giving effect thereto, would not result in any
                  increase in the Interested Shareholder's percentage beneficial
                  ownership of any class or series of Capital Stock.

                           e. After such Interested Shareholder has become an
                  Interested Shareholder, such Interested Shareholder shall not
                  have received the benefit, directly or indirectly (except
                  proportionately as a shareholder of the Corporation), of any
                  loans, advances, guarantees, pledges or other financial
                  assistance or any tax credits or other tax advantages provided
                  by the Corporation, whether in anticipation of or in
                  connection with such Business Combination or otherwise.

                  proposed Business Combination and complying with the
                  requirements of the Securities Exchange Act of 1934 and the
                  rules and regulations thereunder (the "Act") (or any

         The Board of Directors shall not approve, adopt or recommend any
proposal to enter into a Business Combination, or any offer of any person, other
than the Corporation, to make a tender or exchange offer for any capital stock
of the Corporation, unless and until the Board of Directors shall first
establish a procedure for evaluating, and shall have evaluated, the proposal or
offer, and determined that it would be in compliance with all applicable laws
and in the best interests of the Corporation and its shareholders. In connection
with its evaluation, the Board of Directors may seek and obtain the advice of
independent investment counsel, may seek and rely upon an opinion of legal
counsel and other independent advisers, and may test such compliance with laws
in any state or federal court or before any state or federal administrative

might be achieved in a negotiated sale OF the Corporation as whole, and premiums
over trading prices that have been proposed or offered with respect to
securities of other companies in the past in connection with similar offers; (b)
the business, financial condition and earnings prospects of the acquiring person
or entity and the competence, experience and integrity of the acquiring person
or entity and their or its management; and (c) the potential social and economic
impact of the offer and its consummation on the communities in which the
Corporation and its subsidiaries operate or are located and upon the
Corporation, its subsidiaries, and their employees, and customers.

                                STOCK REDEMPTION

         A. In the event that any person becomes the beneficial owner, directly
or indirectly, of thirty (30%) percent or more of the outstanding shares of the
common stock and any of such shares of common stock were acquired pursuant to a
tender offer (such person hereinafter referred to as an "Acquiring Person"),
each holder of shares of common stock, other than the Acquiring Person or a
transferee of the Acquiring Person, shall have the right until and including the
forty-fifth (45th) day following the date of mailing the notice to holders of
shares of common stock referred to in Section C herein to tender the shares of
common stock held by such holder to the Corporation for repurchase by the
Corporation at the Repurchase Price determined as provided in Section E herein,
and each holder, other

                                      -14-


than the Acquiring Person or a transferee of the Acquiring Person, of securities
convertible into shares of common stock or of options, warrants, or rights
exercisable to acquire shares of common stock, shall have the right
simultaneously with the conversion of such securities or exercise of such
options, warrants, or rights to tender the shares of common stock to be received
thereupon by such holder to the Corporation for repurchase by the Corporation at
the Repurchase Price; provided that no holder of shares of common stock shall
have any right to tender shares of common stock redeemed by the Corporation
pursuant to this Article X if the Corporation, acting pursuant to the action of
two-thirds (2/3rds) of the members of its Board of Directors, shall within ten
(10) days following the announcement or publication of such tender offer or
following any amendment to such tender offer recommend to the holders of shares
of common stock that such tender offer be accepted by such holders.

                  1. The term "person" shall include an individual, a
         corporation, partnership, trust or other entity. When two or more
         persons act as a partnership, limited partnership, syndicate, or other
         group or otherwise in concert for the purpose of acquiring shares of
         Common Stock, such partnership, syndicate or group shall be deemed a
         "person."

                  2. For the purpose of determining whether a person is an
         Acquiring Person, such person shall be deemed to own beneficially (i)
         all shares of common stock the voting power of which such person
         controls or shares, (ii) all shares of common stock which such person
         has the immediate or future right to acquire, directly or indirectly,
         pursuant to agreements, through the exercise of options, warrants or
         rights or through the conversion of convertible securities or
         otherwise; and all shares of common stock which such person has the
         right to acquire in such manner shall be deemed to be outstanding
         shares, but shares of common stock which any other unaffiliated person
         has the right to acquire in such manner shall not be deemed to be
         outstanding shares.

                  3. The acquisition of shares of common stock by the
         Corporation or by any person controlled by the Corporation shall not
         give rise to the right in any person to have shares of common stock
         redeemed pursuant to this Article X.

                  4. The right to tender shares of common stock to the
         Corporation for repurchase pursuant to this Article X shall attach to
         such shares and shall not be personal to the holder thereof.

                  5. The term "tender offer" shall mean an offer to acquire or
         an acquisition of shares of common stock pursuant to a request or

         shares of common stock from holders of such shares in privately
         negotiated transactions or in transactions effected through a broker or
         dealer.

                  7. Subject to the provisions of Subparagraph B.2 herein,
         "outstanding shares" shall mean shares of common stock which at the
         time in question have been issued by the Corporation and not reacquired
         and held or retired by it or held by any Subsidiary of the Corporation.

         C. Procedure:

                  1. Not later than twenty days following the date on which the
         Corporation receives credible notice that any person has become an

         rights so to tender pursuant to Paragraph A of this Article) as of a
         date not more than ten (10) days prior to the date of the mailing
         pursuant to this Paragraph C and shall advise each such holder of the
         right to tender shares for repurchase by the Corporation and the
         procedures for such tender and repurchase. In the event that the
         Corporation fails to give notice as required by this Paragraph C, any
         holder entitled to receive such notice may serve written demand upon
         the Corporation to give such notice. If within ten days after the
         receipt of written demand the Corporation fails to give the required
         notice, such holder may at the expense and on behalf of the Corporation
         take such reasonable action as may be appropriate to give notice or to
         cause notice to be given pursuant to this Paragraph C.

                  2. In the event shares of common stock become subject to
         rights of repurchase in accordance with this Article X, the Directors
         of the Corporation shall designate a Repurchase Agent, which shall be a
         corporation or association (i) organized and doing business under the
         laws of the United States or any State, (ii) subject to supervision or
         examination by Federal or State authority, (iii) having combined
         capital and surplus of at least $5,000,000 and (iv) having the power to
         exercise corporate trust powers.

                  3. For a period of forty-five (45) days from the date of the
         mailing of the notice to holders of shares of common stock referred to
         in this Paragraph C, holders of shares of common stock and other
         persons entitled to tender shares of common stock to the Corporation
         for repurchase pursuant to this Article X may, at their option, deposit
         certificates representing all or less than all of the shares of common
         stock held

                                      -16-


         of record by them with the Repurchase Agent, together with written
         notice that the holder is tendering such shares for repurchase pursuant
         to this Article X.

                  4. The Corporation shall promptly deposit in trust with the
         Repurchase Agent cash in an amount equal to the aggregate Repurchase
         Price of all of the shares of common stock deposited with the
         Repurchase Agent for purposes of repurchase.

                  5. As soon as practicable after receipt by the Repurchase
         Agent of the cash deposit by the Corporation referred to in this
         Paragraph C, the Repurchase Agent shall issue its checks payable to the
         order of the persons entitled to receive the Repurchase Price of all of
         the shares of common stock in respect of which such cash deposit was
         made.

         D. All shares of common stock with respect to which repurchase has been
effected pursuant to this Article X shall thereupon be retired.

         E. The Repurchase Price shall be the amount payable by the Corporation
in respect of each share of common stock tendered for repurchase pursuant to
this Article X and shall be the greater amount determined on either of the
following bases:

                  (i) The highest price per share of common stock, including any
         commission paid to brokers or dealers for solicitation or whatever, at
         which shares of common stock held by the Acquiring Person were acquired
         pursuant to a tender offer regardless of when such tender offer was
         made, or were acquired pursuant to any market purchase or otherwise
         within eighteen months prior to the notice to holders of shares of
         common stock referred to in Paragraph C herein. For purposes of this
         subsection (i), if the consideration paid in any such acquisition of
         shares of common stock consisted, in whole or part, of consideration
         other than cash, the Board of Directors of the Corporation shall take
         such action, as in its judgment it deems appropriate, to establish the
         cash value of such consideration, but such valuation shall not be less
         than the cash value, if any, ascribed to such consideration by the
         Acquiring Person; or

                  (ii) The highest sale price per share of common stock for any
         trading day during the eighteen months prior to the notice to holders
         of shares of common stock referred to in Paragraph C herein. For
         purposes of this subsection (ii), the sale price for any trading day
         shall be the mean of the closing high bid and low asked price per share
         of common stock, or if the shares of common stock are traded on a
         national securities exchange, the last sale price per share of common
         stock.

                                      -17-


         The determinations to be made pursuant to this Paragraph E shall be
made by the Board of Directors not later than the date of the notice to holders
of shares of common stock referred to in Paragraph C herein. In making such
determinations the Board of Directors may engage such persons and utilize
employees and agents of the Corporation, who will, in the judgment of the Board
of Directors, be of assistance to the Board of Directors.

         The determinations to be made pursuant to this Paragraph E, when made
by the Board of Directors acting in good faith, shall be conclusive and binding
upon the Corporation and its shareholders, including any person referred to
herein.

         F. No amendment or repeal of this Article X adopted after the notice to
holders of shares of common stock referred to in Paragraph C 3 herein shall
affect the holders' rights of tender for repurchase as to any shares of common
stock theretofore or thereafter deposited with the Repurchase Agent for
repurchase by the corporation under this Article X pursuant to such notice or
any subsequent notice given pursuant to Paragraph G of this Article X.

         G. In the event that repurchase pursuant to this Article X of all or
any part of the shares of common stock is prohibited or prevented by Minnesota
Business Corporation Act, Chapter 302A of Minnesota Statutes or any similar
provision hereafter enacted or by the business combinations and securities or
similar subject matter statutes or regulations of the State of Minnesota:

                  1. The Corporation shall so advise the holders of shares of
         common stock entitled to the rights of tender for repurchase provided
         in this Article X and shall advise them of their modified rights of
         tender for repurchase as provided in this Paragraph in the notice
         required by Paragraph C of this Article;

                  2. The Corporation shall take all of the actions required by
         this Article to be taken with respect to a repurchase of all of the
         shares of common stock deposited with the Repurchase Agent for purposes
         of repurchase, provided that it shall determine the number of shares of
         common stock which may legally be repurchased at the Re purchase Price
         and cause the repurchase only of such number of shares by any
         reasonable method of allotment selected by the Repurchase Agent, and
         provided further that the Corporation shall not repurchase a fraction
         of a share. After the Corporation's deposit in trust with the
         Repurchase Agent of the cash deposit provided for in Paragraph C in an
         amount equal to the aggregate Repurchase Price of all of the shares of
         common stock to be repurchased at the time pursuant to this Paragraph
         G, the Repurchase Agent shall issue its checks as provided in Paragraph
         C and return certificates evidencing shares of common stock not
         repurchased to the record holders thereof;

                                      -18-


                  3. The Corporation shall have a continuing obligation to
         repurchase shares of common stock deposited with the Repurchase Agent
         at times and from time to time by record holders other than the
         Acquiring Person or an assignee of the Acquiring Person pursuant to
         notices issued by the Corporation in each year succeeding the year in
         which the first notice of rights to tender for repurchase is given
         pursuant to this Article until all shares so deposited are repurchased.
         In each such year the Corporation shall determine the number of shares
         of common stock which may legally be repurchased at the Repurchase
         Price, which price for each such year shall be the Repurchase Price
         originally established for the first repurchase pursuant to this
         Article provided that, such Repurchase Price shall be increased by
         eight percent (8%) per year compounded, and all of the actions required
         to be taken by this Paragraph G by the Corporation and the Repurchase
         Agent for the first repurchase shall be repeated. Said repurchase
         notices shall be issued annually no later than 120 days after the close
         of the Corporation's fiscal year commencing with the first full fiscal
         year after the first notice of rights to tender for repurchase pursuant
         to this Article X, provided that repurchases may be effected more
         frequently at the election of the corporation should funds be legally
         available therefor; and

                  4. Until all of the shares of common stock deposited with the
         Repurchase Agent pursuant to the last notice of repurchase are
         repurchased pursuant to this Article, the Corporation shall pay no
         dividends on any of its outstanding capital stock, whether outstanding
         at the time the Corporation issues its first notice pursuant to
         Paragraph C or at any time thereafter.

         H. The provision of this Article X shall control with respect to the
price, terms, times, and means of repurchase of shares in circumstances to which
it is applicable, notwithstanding any provision of Article VIII of these Amended
And Restated Articles.

These Amended and Restated Articles of Incorporation have been approved pursuant
to chapter 302A, Minnesota Statutes.

I certify that I am authorized to execute this amendment and I further certify
that I understand that by signing this amendment, I am subject to the penalties
of perjury as set forth in section 609.48 as if I had signed this amendment
under oath.
