Corporation except in accordance with the procedures set forth above in this 
subparagraph D. The Chairman of the Meeting of the Shareholders shall, if the 
facts warrant, determine and declare to the meeting that business was not

     To the fullest extent possible permitted by law, a director shall have 
no personal liability to the Corporation or its shareholders for breach of 
fiduciary duty as a director.  Any amendment to or repeal of this Article VI 
shall not adversely affect any right to protection of a director of the 
Corporation for or with respect to any acts or omissions of such director 
occurring prior to such amendment or repeal.

                                   ARTICLE VII

     The business and affairs of the Corporation shall be managed by or under 
the direction of the Board of Directors.

     A.   NUMBER, ELECTION AND TERMS OF DIRECTORS.  Except as otherwise fixed 
pursuant to the provisions relating to the rights of holders of any class or 
series of stock having a preference over the Corporation's common stock as to 
dividends or upon liquidation to elect additional directors under specified 
circumstances, the number of directors of the Corporation shall be fixed from 
time to time by or pursuant to the bylaws but in no event shall be less than 
three (3) or more than seven (7) in number.  The directors, other than those 
who may be elected by the holders of any class or series of stock having a 
preference over the common stock as to dividends or upon liquidation, shall 


                                      -3-




be classified with respect to the time for which they may severally hold 
office, into three classes, as nearly equal in number as possible, as shall 
be provided in the manner specified in the bylaws, one class to hold office 
initially for a term expiring at the 1999 Annual Meeting of Shareholders, 
another class to hold office initially for a term expiring at the 1997 Annual 
Meeting of Shareholders, and another class to hold office initially for a 
term expiring at the 1995 Annual Meeting of Shareholders, with the members of 
each class to hold office until their successors have been duly elected and 
qualified.  At each Annual Meeting of Shareholders, the successors to the 
class of directors whose term expires at that meeting shall be elected to 
hold office for a term expiring at the Annual Meeting of Shareholders held in 
the year following the year of their election and until their successors have 
been duly elected and qualified.

     B.   SHAREHOLDER NOMINATION OF DIRECTOR CANDIDATES.  Only persons who 
are nominated in accordance with the procedures set forth in this 
subparagraph shall be eligible for election as directors.  Advance notice of 
nomination for the election of directors, other than by the Board of 
Directors or a duly authorized committee thereof or any authorized officer of 
the Corporation to whom the Board of Directors shall have delegated such 
authority, and information concerning nominees, shall be given in the manner 
provided in this subparagraph B. Nominations by shareholders shall be made 
pursuant to timely notice in writing to the Secretary of the Corporation.  To 
be timely, a shareholder's notice shall be delivered to or mailed and 
received at the principal offices of the Corporation not less than thirty 
(30) days nor more than fifty (50) days prior to the meeting; provided, 
however, that in the event less than thirty (30) days' notice or prior public 
disclosure of the date of the meeting is given or made to the shareholders, 
notice by the shareholder to be timely must be so received not later than the 
close of business on the 10th day following the day on which such notice of 
the date of the meeting was mailed or public disclosure was made. Such 
shareholder's notice shall set forth (a) as to each person whom the 
shareholder proposes to nominate for election or re-election, all information 
relating to such person that is required to be disclosed in solicitation of 
proxies for election of directors, or is otherwise required, in each case 
pursuant to Regulation 14A under the Securities Exchange Act of 1934, as 
amended (including such person's written consent to being named in the proxy 
statement as a nominee and to serving as a director if elected); and (b) as 
to the shareholder giving notice (i) the name and address, as they appear on 
the Corporation's books, of such shareholder, and (ii) the class and number 
of shares of the Corporation which are beneficially owned by such shareholder.

     No person shall be eligible for election as a director of the
     Corporation unless nominated in accordance with the procedures set
     forth above in this subparagraph B.  The Chairman of the Meeting of
     the Shareholders shall, if the facts warrant, determine and declare to
     the meeting that a nomination was not made in accordance with the
     procedures prescribed in this subparagraph B and, if he should so
     determine, he shall so declare to the meeting and the defective
     nomination shall be disregarded.

     C.   NEWLY CREATED DIRECTORSHIPS AND VACANCIES.  Except as otherwise 
fixed pursuant to the provisions relating to the rights of holders of any 
class or series of stock having a preference over the common stock as to 
dividends or upon liquidation to elect additional directors under 


                                      -4-




specified circumstances, newly created directorships resulting from any 
increase in the authorized number of directors and any vacancies on the Board 
of Directors resulting from death, resignation, retirement, disqualification, 
removal from office or other cause shall be filled by a majority vote of the 
directors then in office, and directors so chosen shall hold office for a 
term expiring at the next Annual Meeting of Shareholders at which term of the 
class to which they have been elected expires.  No decrease in the number of 
directors constituting the Board of Directors shall shorten the term of any 
incumbent director.

     D.   REMOVAL.  Subject to the rights of holders of any class or series 
of stock having a preference over the common stock as to dividends or upon 
liquidation to elect additional directors under specified circumstances, any 
director or directors may be removed from office at any time, but only for 
cause and only by the affirmative vote of (i) the holders of at least 
seventy-five (75%) percent of the voting power of the then outstanding shares 
of capital stock of the Corporation entitled to vote generally in the 
election of directors, voting together as a single class, or (ii) the 
majority of the Board of Directors.  Except as may otherwise be provided by 
law, cause for removal shall be construed to exist only if the director whose 
removal is proposed has been convicted of a felony by a court of competent 
jurisdiction and such conviction is no longer subject to direct appeal or has 
been adjudged by a court of competent jurisdiction to be liable for 
negligence or misconduct in the performance of his duty to the Corporation in 
a matter of substantial importance to the Corporation, and such adjudication 
is no longer subject to direct appeal.

     E.   AMENDMENT, REPEAL, ETC.  Notwithstanding the fact that a lesser 
percentage may be specified by law, the Articles of Incorporation and bylaws 
of the Corporation, the affirmative vote of the holders of seventy-five (75%) 
percent of the voting power of the then outstanding shares of capital stock 
of the Corporation entitled to vote generally in the election of directors, 
voting together as a single class, shall be required to amend or repeal, or 
adopt any provision inconsistent with, subparagraphs A through E of this 
Article VII.

defined) shall require the affirmative vote of not less than seventy-five 
(75%) percent of the votes entitled to be cast by holders of all then 
outstanding shares of Voting Stock (as hereinafter defined), voting together 
as a single class.  Such affirmative vote shall be required notwithstanding 
the fact that no vote may be required, or that a lesser percentage or 
separate class vote may be specified, by law or by any other provision of 
these Articles of Incorporation or in any agreement with any national 
securities exchange or otherwise.

     B.   The provisions of Section A of this Article VIII shall not be 
applicable to any particular Business Combination, and such Business 
Combination shall require only such affirmative 


                                      -5-




vote, if any, as is required by law or by any other provision of these 
Articles of Incorporation or in any agreement with any national securities

subparagraphs 1 or 2 are met:

          prior to the date of the first public announcement of the proposed

          (ii) the Fair Market Value per share of common stock on the
          Announcement Date or on the date on which the Interest Shareholder
          became an Interested Shareholder (such later date being referred to
          herein as the "Determination Date"), whichever is higher.

     b.   The aggregate amount of cash and the Fair Market Value as of the date

                                      -6-




          (ii) the Fair Market Value per share of such class or series of

          whichever is higher, and

          would be entitled in the event of any voluntary or involuntary
          liquidation, dissolution or winding up of the affairs of the
          Corporation, regardless of whether the Business Combination to be
          consummated constitutes such an event.

          The provisions of this Paragraph 2.b shall be required to be met with
          respect to every class or series of outstanding Capital Stock, whether

     c.   The consideration to be received by holders of a particular class or
          series of outstanding Capital Stock shall be in cash or in the same
          form as previously has been paid by or on behalf of the Interested
          Shareholder in connection with 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 the form used
          to acquire beneficial ownership of the largest number of shares of
          such class or series of Capital Stock previously acquired by the
          Interested Shareholder.

          The price determined in accordance with Paragraphs 2.a and 2.b of
          Section B of this Article VIII shall be subject to appropriate
          adjustments 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,
          expect 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 reflect any
          stock dividend, stock split, combination of shares 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 


                                      -7-




          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.

     f.   A proxy or information statement describing the 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 subsequent provisions replacing such Act, rules or
          regulations) shall be mailed to all shareholders of the Corporation at
          least 30 days prior to the consummation of such Business Combination
          (whether or not such proxy or information statement is required to be
          mailed pursuant to the Act or subsequent provisions).  The proxy or
          information statement shall contain on the first page thereof, in a
          prominent place, any statement as to the advisability (on
          inadvisability) of the Business Combination that a majority of the
          Continuing Directors may choose to make and, if deemed advisable by a
          majority of the Continuing Directors, the opinion of an investment
          banking firm selected by a majority of the Continuing Directors as to
          the fairness (or lack of fairness) of the terms of the Business
          Combination from a financial point of view to the holders of the
          outstanding shares of Capital Stock other than the Interested
          Shareholder and its Affiliates (as hereinafter defined) or Associates
          (as hereinafter defined).

     g.   Such Interested Shareholder shall not have made or caused to be made
          any major change in the Corporation's business or equity capital
          structure without the approval of a majority of the Continuing
          Directors.

          into equity securities of any Subsidiary, that is beneficially owned
          by any Interested Shareholder or any Affiliate or Associate of any

fiduciary duty, obligation or responsibility on the Board of Directors, or 
any member thereof, or the Continuing Directors, or any of them, to approve 
such Business Combination or recommend its adoption or approval to the 
shareholders of the Corporation, nor shall such compliance limit, prohibit or

                              EVALUATION DIRECTIVES

     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 advisors, and may 
test such compliance with laws in any state or federal court or before any 
state or federal administrative agency that may have appropriate 
jurisdiction.  In connection with its evaluation as to the best interests of 
the Corporation and its shareholders, the Board of Directors shall consider 
all factors that it deems relevant or the shareholders may deem relevant, 
including without limitation: (a) the adequacy and fairness of the 
consideration to be received by the Corporation and/or its shareholders 
considering the future prospects of the Corporation and its business, 
historical trading prices of the Corporation's capital stock, the price that 
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.

     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 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 


                                     -13-




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 invitation
     for tenders or an offer to purchase such shares for cash, securities or any
     other consideration.

     6.   The term "market purchase" shall mean the acquisition of shares of
     common stock from holders of such shares in privately negotiated
     transactions or in transactions effected through a broker or dealer.


                                     -14-




     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 Acquiring Person
     whereupon the rights shall be engendered to tender shares of common stock
     to the Corporation for repurchase by the Corporation under this Article X,
     the Corporation shall give written notice, by first class mail, postage
     prepaid, at the addresses shown on the records of the Corporation, to each
     holder of record of shares of common stock (and to any other person known
     by the Corporation to have 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 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 


                                     -15-




     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.

     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 


                                     -16-



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 Repurchase 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;

     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


                                     -17-




     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.

into by and between DynEco Corporation, a Minnesota corporation ("DYNECO"), 
also known as the acquiring corporation, and DynEco International, Inc., a

     WITNESSETH:

     WHEREAS, DYNECO is a corporation duly organized and existing under the 
laws of the State of Minnesota, having an authorized capital of 10,000,000 
shares of Common Stock, $0.01 Par Value, of which 282,184 shares are issued

of the State of Minnesota, having an authorized capital of 10,000,000 shares 
of capital stock of which 3,762,167 shares are issued and outstanding as of

     WHEREAS, the respective boards of directors of DYNECO and DI have each 
duly approved this Plan of Exchange (the "Plan") providing for the exchange 
of shares of DYNECO for shares of capital stock of DI on the terms set forth 
herein;

incorporated by reference and made a part hereof, dated as of June 18, 1993, 
setting forth certain representations, warranties, covenants, agreements, and 
conditions in connection with said Exchange.

     NOW, THEREFORE, based on the foregoing premises and in consideration of 
the mutual covenants and agreements herein contained, and for the purpose of 
setting forth the terms and conditions of said exchange and the manner and 
basis of causing the shares of DI Common Stock to be converted into shares of 
Common Stock of DYNECO (the "Common Stock of DYNECO"), and such other 
provisions as are deemed necessary or desirable, the parties hereto have 
agreed and do hereby agree, subject to the approval and adoption of this Plan 
by the requisite vote of the securities holders of DI, and subject to the 
conditions hereinafter set forth, as follows:

                                    ARTICLE I

                  TERMS, MANNER, AND BASIS OF EXCHANGING SHARES

     The terms, manner, and basis of exchanging the shares of Common Stock of 
DI for shares of the Common Stock of DYNECO, and the mode of carrying the 
Exchange into effect are as follows:





     (a)  Each one share of the Common Stock of DI outstanding on the Effective
     Date of the Exchange shall, without any action on the part of the holder
     thereof, be converted into one (1) fully paid and nonassessable restricted
     share of Common Stock of DYNECO, which share of Common Stock of DYNECO
     shall thereupon be duly and validly issued and outstanding, fully paid, and
     nonassessable, and shall not be liable to any further call, nor shall the
     holder thereof be liable for any further payments with respect thereto. 
     After the Effective Date of the Exchange, each holder of an outstanding
     certificate prior thereto represented shares of the Common Stock of DI
     shall be entitled, on surrender thereof to the transfer and exchange agent
     of DYNECO and on execution and delivery of a representation letter in a
     form acceptable to DYNECO, to receive in exchange therefor a certificate or
     certificates representing the number of whole shares of the Common Stock of
     DYNECO into which the shares of Common Stock of DI so surrendered shall
     have been converted as set forth above, of such denominations and
     registered in such names as such holder may request.  Until so surrendered,
     each such outstanding certificate that, prior to the Effective Date of the
     Exchange, represented shares of the Common Stock of DI shall for all
     purposes evidence the ownership of the shares of Common Stock of DYNECO
     into which shares of Common Stock of DI shall have been converted; provided
     that dividends or other distributions that are payable in respect to shares
     of Common Stock of DYNECO shall be set aside by DYNECO and shall not be
     paid to holders of certificates, representing such shares of Common Stock
     of DI until such certificates shall have been surrendered in exchange for
     certificates representing shares of Common Stock of DYNECO, and on such
     surrender, holders of such shares shall be entitled to receive such
     dividends or other distributions without interest.  DYNECO shall not issue
     any fractional interest in shares of Common Stock of DYNECO in connection
     with the aforesaid exchange and the number of shares of DYNECO to which DI
     shares will be exchanged shall be rounded to the nearest whole number of
     shares.  DYNECO shall be entitled to exchange the certificates representing
     shares of DI so acquired for a certificate or certificates representing a
     like number of shares of DI registered in the name of DYNECO on the books
     and records of DI.

     (b)  All shares of Common Stock of DYNECO for which shares of the Common
     Stock of DI shall have been exchanged pursuant to this Article shall be
     issued in full satisfaction of all rights pertaining to the shares of
     Common Stock of DI.

     (c)  If any certificate for shares of Common Stock of DYNECO is to be
     issued in a name other than that in which the certificate surrendered in
     exchange therefor is registered, it shall be a condition of the issuance
     thereof that the certificate so surrendered shall be properly endorsed and
     otherwise in proper form for transfer and that the person requesting such
     exchange pay to DYNECO or any agent designated by it any transfer or other
     taxes required by reason of the issuance of a certificate for shares of
     Common Stock of DYNECO in any name other than that of the registered holder
     of the certificate surrendered, or establish to the satisfaction of DYNECO
     or any agent designated by it that such tax has been paid or is not
     payable.


                                      -2-




     (d)  There are no options, warrants, or conversion rights outstanding with
     respect to the shares of Common Stock of DI except those identified in DI's
     Schedules appended to the Agreement.

                                   ARTICLE II

                    OTHER PROVISIONS WITH RESPECT TO EXCHANGE

     This Plan shall be submitted to a vote of a meeting of securities 
holders of DI as provided by the laws of the State of Minnesota.  After the 
approval or adoption thereof by the securities holders of DI in accordance 
with the requirements of the laws of the State of Minnesota, all required 
documents shall be executed, filed, and recorded in accordance with all 
requirements of the State of Minnesota and subject to the terms and 
conditions of the Agreement.

                                   ARTICLE III

        APPROVAL AND EFFECTIVE DATE OF THE MERGER; MISCELLANEOUS MATTERS
