ITEM 5.  TENDER OFFER AND MERGER.

     On December 15, 1997, the registrant entered into an Agreement and Plan
of Merger (the "Merger Agreement") with Sulzer Medica Ltd., a Swiss corporation
("Parent"), and Sulzer Medica Orthopedics Acquisition Corp., a Minnesota
corporation and wholly owned indirect subsidiary of Parent ("Purchaser").
Subject to the terms and conditions of the Merger Agreement, Purchaser will
commence a cash tender offer for all of the registrant's issued and outstanding
shares of Common Stock for $52.00 per share.  The tender offer is conditioned
upon the holders of at least a majority of shares of the registrant's Common
Stock tendering their shares.  Following the tender offer, Purchaser will be
merged into the registrant, with the registrant surviving as a wholly owned
indirect subsidiary of Parent (the "Merger").  In the Merger, those shareholders
of the registrant who did not tender their shares (other than Parent and its
affiliates and shareholders exercising dissenters rights) will be entitled to
receive $52.00 per share of Common Stock held by them.

         AGREEMENT AND PLAN OF MERGER, dated as of December 15, 1997 (this
"AGREEMENT"), among SULZER MEDICA LTD, a corporation organized under the laws of
Switzerland ("PARENT"), SULZER MEDICA ORTHOPEDICS ACQUISITION CORP., a Minnesota
corporation and an indirect wholly owned subsidiary of Parent ("PURCHASER"), and
SPINE-TECH, INC., a Minnesota corporation (the "COMPANY") (Purchaser and the
Company being sometimes hereinafter referred to as the "CONSTITUENT
CORPORATIONS").

         WHEREAS, the Boards of Directors of Parent, Purchaser and the Company
have each determined that it is in the best interests of their respective
shareholders for Parent to acquire the Company upon the terms and subject to the
conditions set forth herein;

         WHEREAS, it is proposed that Purchaser shall make a cash tender offer
(as it may be amended from time to time as permitted hereunder, the "OFFER") to
acquire all of the issued and outstanding shares of common stock, $0.01 par
value, of the Company ("COMPANY COMMON STOCK") (such shares of Company Common
Stock, including the Company Rights (as defined in Section 3.03) associated with
such shares, being hereinafter collectively referred to herein as "SHARES") for
$52.00 per Share (such amount, or any greater amount per Share paid pursuant to
the Offer, being the "PER SHARE AMOUNT") net to the seller in cash, upon the
terms and subject to the conditions of this Agreement and the Offer;

         WHEREAS, the Board of Directors of the Company (the "BOARD") has
unanimously consented to the making of the Offer by Purchaser and resolved and
agreed to recommend that holders of Shares tender their Shares pursuant to the
Offer;

         WHEREAS, the Boards of Directors of Parent (on its own behalf and as
the sole shareholder of Purchaser), Purchaser and the Company have each approved
this Agreement and the merger (the "MERGER") of Purchaser with and into the
Company in accordance with the Minnesota Business Corporation Act (the
"MINNESOTA LAW") following the consummation of the Offer and upon the terms and
subject to the conditions set forth herein.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, Parent, Purchaser and the Company hereby agree as follows:

                                      ARTICLE I

                                      THE OFFER


<PAGE>

                                          3

         SECTION 1.01.  THE OFFER.  (a)  Provided that this Agreement shall not
have been terminated in accordance with Section 8.01 and none of the events set
forth in Annex A hereto shall have occurred or be existing (and shall not have
been waived by Purchaser), Purchaser shall commence the Offer as promptly as
reasonably practicable after the date hereof, but in no event later than five
business days after the initial public announcement of Purchaser's intention to
commence the Offer.  The obligation of Purchaser to accept for payment and pay
for Shares tendered pursuant to the Offer shall be subject to the condition (the
"MINIMUM CONDITION") that a number of Shares that, when added to the Shares
already owned by Parent, shall constitute at least a majority of the then
outstanding Shares on a fully diluted basis (including, without limitation, all
Shares issuable upon the conversion of any outstanding convertible securities or
upon the exercise of any outstanding options, warrants or rights (other than the
Company Rights)) shall have been validly tendered and not withdrawn prior to the
expiration of the Offer and also shall be subject to the satisfaction or waiver
of each of the other conditions set forth in Annex A hereto.  Purchaser
expressly reserves the right to waive any such condition, to increase the price
per Share payable in the Offer, and to make any other changes in the terms and
conditions of the Offer; PROVIDED, HOWEVER, that no change may be made which
decreases the price per Share payable in the Offer, reduces the maximum number
of Shares to be purchased in the Offer, changes the form of consideration to be
paid in the Offer, modifies the conditions to the Offer set forth in Annex A
hereto or imposes conditions to the Offer other than those set forth in Annex A
hereto or, except as provided in the next sentence, extends the Offer.
Notwithstanding the foregoing, Purchaser may, without the consent of the
Company, (i) extend the Offer beyond the scheduled expiration date, which shall
be 20 business days following the commencement of the Offer, if, at the
scheduled expiration of the Offer, any of the conditions to Purchaser's
obligation to accept for payment, and to pay for, the Shares, shall not be
satisfied or waived, (ii) extend the Offer for any period required by any rule,
regulation or interpretation of the Securities and Exchange Commission (the
"SEC") or the staff thereof applicable to the Offer, or (iii) extend the Offer
for an aggregate period of not more than 5 business days beyond the latest
applicable date that would otherwise be permitted under clause (i) or (ii) of
this sentence, if, as of such date, all of the conditions to Purchaser's
obligations to accept for payment, and to pay for, the Shares are satisfied or
waived, but the number of Shares validly tendered and not withdrawn pursuant to
the Offer equals 80 percent or more, but less than 90 percent, of the
outstanding Shares.  The Per Share Amount shall, subject to applicable
withholding of taxes, be net to the seller in cash, upon the terms and subject
to the conditions of the Offer.  Subject to the terms and conditions of the
Offer, Purchaser shall, and Parent shall cause Purchaser to, promptly after
expiration of the Offer, accept for payment and pay for all Shares validly
tendered and not withdrawn.

         (b)  As promptly as practicable on the date of commencement of the
Offer, Purchaser shall file with the SEC a Tender Offer Statement on
Schedule 14D-1 (together with


<PAGE>

                                          4

all amendments and supplements thereto, the "SCHEDULE 14D-1") with respect to
the Offer.  The Schedule 14D-1 shall contain or shall incorporate by reference
an offer to purchase (the "OFFER TO PURCHASE") and forms of the related letter
of transmittal and any related summary advertisement (the Schedule 14D-1, the
Offer to Purchase and such other documents, together with all supplements and
amendments thereto, being, collectively, the "OFFER DOCUMENTS").  Purchaser
shall disseminate the Offer to Purchase, the related letter of transmittal and
other Offer Documents to the extent required by applicable federal securities
laws.  The Offer Documents will comply in all material respects with the
provisions of applicable federal securities laws.  Each of Parent, Purchaser and
the Company agrees to correct promptly any information provided by it for use in
the Offer Documents which shall have become false or misleading, and Parent and
Purchaser further agree to take all steps necessary to cause the Schedule 14D-1
as so corrected to be filed with the SEC and the other Offer Documents as so
corrected to be disseminated to holders of Shares, in each case as and to the
extent required by applicable federal securities laws.

         (c)  Purchaser and Parent will file with the Commissioner of Commerce
of the State of Minnesota any registration statement relating to the Offer
required to be filed pursuant to Chapter 80B of the Minnesota Statutes.

         SECTION 1.02.  COMPANY ACTION.  (a)  The Company hereby consents to
the Offer and represents that (i) the Board, at a meeting duly called and held
on December 15, 1997, and a special committee of the Board, formed in accordance
with Section 302A.673 of the Minnesota Law, at a meeting duly called and held on
December 15, 1997, have, in each case, unanimously (A) determined that this
Agreement and the transactions contemplated hereby are in the best interests of
the Company and its shareholders, (B) approved this Agreement, the Merger, the
Offer and the other transactions contemplated hereby and (C) resolved to
recommend that the shareholders of the Company accept the Offer and approve and
adopt this Agreement and the transactions contemplated hereby, and (ii) Piper
Jaffray Inc. ("PIPER JAFFRAY") has delivered to the Board its opinion that the
consideration to be received by the holders of Shares pursuant to each of the
Offer and the Merger is fair to the holders of Shares from a financial point of
view.   The Company hereby consents to the inclusion in the Offer Documents of
the recommendation of the Board described in the immediately preceding sentence
unless the Board shall determine in good faith that it is necessary to withdraw
such recommendation in accordance with its fiduciary duties to the Company and
its shareholders after consultation with its outside legal counsel..

         (b)  As promptly as practicable on the date of commencement of the
Offer, the Company shall file with the SEC a Solicitation/Recommendation
Statement on Schedule 14D-9 (together with all amendments and supplements
thereto, the "SCHEDULE 14D-9") containing the recommendation of the Board
described in Section 1.02(a), unless the


<PAGE>

                                          5

Board determines in good faith in accordance with Section 6.05(b) an alternative
recommendation to be necessary in accordance with its fiduciary duties to the
Company and its shareholders under applicable law after consultation with its
outside legal counsel.  The Company shall disseminate the Schedule 14D-9 to the
extent required by Rule 14d-9 promulgated under the Securities Exchange Act of
1934, as amended (the "EXCHANGE ACT"), and any other applicable federal
securities laws.  The Schedule 14D-9 will comply in all material respects with
the provisions of applicable federal securities laws.  Each of the Company,
Parent and Purchaser agrees to correct promptly any information provided by it
for use in the Schedule 14D-9 which shall have become false or misleading, and
the Company further agrees to take all steps necessary to cause the
Schedule 14D-9 as so corrected to be filed with the SEC and disseminated to
holders of Shares, in each case as and to the extent required by applicable
federal securities laws.

         (c)  The Company shall promptly furnish Purchaser with mailing labels
containing the names and addresses of all record holders of Shares and with
security position listings of Shares held in stock depositories, each as of a
recent date, together with all other available listings and computer files
containing names, addresses and security position listings of record holders and
beneficial owners of Shares.  The Company shall furnish Purchaser with such
additional information, including, without limitation, updated listings and
computer files of shareholders, mailing labels and security position listings,
and such other assistance as Parent, Purchaser or their agents may reasonably
request.  Subject to the requirements of applicable law, and except for such
steps as are necessary to disseminate the Offer Documents and any other
documents necessary to consummate the Offer or the Merger, Parent and Purchaser
shall, and each of Parent and Purchaser shall cause its affiliates, associates,
agents, representatives and advisors to, hold in confidence the information
contained in such labels, listings and files, shall use such information solely
in connection with the Offer and the Merger, and, if this Agreement shall be
terminated in accordance with Section 8.01 or if the Offer is otherwise
terminated, shall promptly deliver to the Company all copies (whether in human
or machine readable form) of such information and any information derived
therefrom then in their possession or the possession of their agents and
representatives.

PROVIDED, HOWEVER, that, at the Effective Time, by virtue of the Merger and this
Agreement and without any further action by the Constituent Corporations,

         SECTION 2.05.  DIRECTORS AND OFFICERS.  The directors of Purchaser

<PAGE>

                                          7

of the Surviving Corporation and the Minnesota Law, and the officers of the
Purchaser immediately prior to the Effective Time shall be the initial officers
of the Surviving Corporation, in each case until their respective successors are
duly elected or appointed and qualified in accordance with the Articles of
Incorporation and By-laws of the Surviving Corporation and the Minnesota Law.

         SECTION 2.06.  CONVERSION OF SECURITIES.  The manner and basis of
converting the shares of stock of each of the Constituent Corporations is
hereinafter set forth in this Section 2.06.  At the Effective Time, by virtue of
the Merger and without any further action on the part of Purchaser, the Company
or the holders of any of the following securities:

              (a)  Each Share issued and outstanding immediately prior to the
    Effective Time (other than any Shares to be cancelled pursuant to
    Section 2.06(b) and any Dissenting Shares (as hereinafter defined)) shall
    be converted automatically into the right to receive the Per Share Amount
    in cash (the "MERGER CONSIDERATION"), prorated for fractional shares,
    payable, without interest, to the holder of such Share, upon surrender, in
    the manner provided in Section 2.09, of the certificate that formerly
    evidenced such Share and all such Shares, when so converted, shall no
    longer be outstanding and shall automatically be cancelled;

              (b)  Each Share held in the treasury of the Company and each
    Share owned by Purchaser, Parent or any direct or indirect wholly owned
    subsidiary of Parent or of the Company immediately prior to the Effective
    Time shall be cancelled without any conversion thereof and no payment or
    distribution shall be made with respect thereto; and

              (c)  Each share of common stock, par value $0.01 per share, of
    Purchaser issued and outstanding immediately prior to the Effective Time
    shall be converted into and exchanged for one validly issued, fully paid
    and nonassessable share of common stock, par value $0.01 per share, of the
    Surviving Corporation.

         SECTION 2.07.  OPTIONS.  All outstanding Employee Stock Options (as

pay each holder of an Employee Stock Option or S&N Option, as the case may be,
the cash amount determined in accordance with Section 6.06(a) or Section
6.07(a), respectively.

         SECTION 2.08.  DISSENTING SHARES.  (a)  Notwithstanding any provision
of this Agreement to the contrary, Shares that are outstanding immediately prior
to the Effective Time


<PAGE>

                                          8

and which are held of record or beneficially owned by persons who shall not have
voted such Shares in favor of the Merger and who shall have properly exercised
dissenters' rights with respect to such Shares in accordance with
Sections 302A.471 and 302A.473 of the Minnesota Law (collectively, the
"DISSENTING SHARES") shall not be converted into the Merger Consideration.  Such
shareholders shall be entitled to receive payment of the fair value of such
Shares held by them in accordance with the provisions of such Section 302A.473,
except that all Dissenting Shares held of record or beneficially owned by
persons who shall have failed to perfect or who effectively shall have withdrawn
or lost their dissenters' rights to such Shares under such Section 302A.473
shall thereupon be deemed to have been converted into, as of the Effective Time,
the right to receive the Merger Consideration, without any interest thereon,
upon surrender, in the manner provided in Section 2.09, of the certificate or
certificates that formerly evidenced such Shares.

         (b)  The Company shall give Parent (i) prompt notice of any notice of
intent to demand the fair value of any Shares received by the Company pursuant
to Section 302A.473 of the Minnesota Law, withdrawals of such notices, and any
other instruments served pursuant to the Minnesota Law and received by the
Company with respect to Dissenting Shares and (ii) the opportunity to direct all
negotiations and proceedings with respect to the exercise of dissenters' rights
under the Minnesota Law.  The Company shall not, except with the prior written
consent of Parent, make any payment with respect to the exercise of dissenters'
rights or offer to settle or settle any such rights.

         SECTION 2.09.  SURRENDER OF SHARES; STOCK TRANSFER BOOKS.  (a)  Prior
to the Effective Time, Purchaser shall designate a bank or trust company located
in the United States having capital surplus and undivided profits exceeding
$500,000,000 to act as agent (the "PAYING AGENT") for the holders of Shares in
connection with the Merger to receive the funds to which holders of Shares shall
become entitled pursuant to Section 2.06(a).  Such funds shall be invested by
the Paying Agent as directed by the Surviving Corporation.

         (b)  Promptly after the Effective Time, the Surviving Corporation
shall cause to be mailed to each person who was, at the Effective Time, a holder
of record of Shares entitled to receive the Merger Consideration pursuant to
Section 2.06(a):  (i) a form of letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the certificates
evidencing such Shares (the "CERTIFICATES") shall pass, only upon proper
delivery of the Certificates to the Paying Agent) and (ii) instructions for use
in effecting the surrender of the Certificates pursuant to such letter of
transmittal.  Upon surrender to the Paying Agent of a Certificate, together with
such letter of transmittal, duly completed and validly executed in accordance
with the instructions thereto, and such other documents as reasonably may be
required pursuant to such instructions, the holder of such Certificate shall be
entitled promptly to receive in exchange therefor the Merger Consideration for
each Share formerly evidenced


<PAGE>

                                          9

by such Certificate, and such Certificate shall then be cancelled.  No interest
shall accrue or be paid on the Merger Consideration payable upon the surrender
of any Certificate for the benefit of the holder of such Certificate.  If
payment of the Merger Consideration is to be made to a person other than the
person in whose name the surrendered Certificate is registered on the stock
transfer books of the Company, it shall be a condition of payment that the
Certificate so surrendered shall be endorsed properly or otherwise be in proper
form for transfer and that the person requesting such payment shall have paid
all transfer and other taxes required by reason of the payment of the Merger
Consideration to a person other than the registered holder of the Certificate
surrendered or shall have established to the satisfaction of the Surviving
Corporation that such taxes either have been paid or are not applicable.

         (c)  In the event any Certificate or Certificates shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
person claiming such Certificate or Certificates to have been lost, stolen or
destroyed, the amount to which such person would have been entitled under
Section 2.09(b) hereof but for failure to deliver such Certificate or
Certificates to the Paying Agent shall nevertheless be paid to such person;
PROVIDED, HOWEVER, that the Surviving Corporation may, in its sole discretion
and as a condition precedent to such payment, require such person to give the
Surviving Corporation a written indemnity agreement in form and substance
reasonably satisfactory to the Surviving Corporation and, if reasonably deemed
advisable by the Surviving Corporation, a bond in such sum as it may reasonably
direct as indemnity against any claim that may be had against the Surviving
Corporation or Parent with respect to the Certificate or Certificates alleged to
have been lost, stolen or destroyed.

         (d)  At any time following the sixth month after the Effective Time,
the Surviving Corporation shall be entitled to require the Paying Agent to
deliver to it any funds which had been made available to the Paying Agent and
not disbursed to holders of Shares (including, without limitation, all interest
and other income received by the Paying Agent in respect of all funds made
available to it), and thereafter such holders shall be entitled to look to the
Surviving Corporation (subject to abandoned property, escheat and other similar
laws) only as general creditors thereof with respect to any Merger Consideration
that may be payable upon due surrender of the Certificates held by them, and
Parent and the Surviving Corporation jointly and severally agree to be liable
for payments required to be made before or after the expiration of such six
month period under Section 2.06(a) hereof or Section 302A.473 of the Minnesota
Law.  Notwithstanding the foregoing, neither the Surviving Corporation nor the
Paying Agent shall be liable to any holder of a Share for any Merger
Consideration delivered in respect of such Share to a public official pursuant
to any abandoned property, escheat or other similar law.



<PAGE>

                                          10

         (e)  At the close of business on the day of the Effective Time, the
stock transfer books of the Company shall be closed and thereafter there shall
be no further registration of transfers of Shares on the records of the Company.
From and after the Effective Time, the holders of Shares outstanding immediately
prior to the Effective Time shall cease to have any rights with respect to such
Shares except as otherwise provided herein or by applicable law.


                                     ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         Except as set forth in the disclosure schedule delivered by the
Company to Parent concurrently with the execution of this Agreement (the
"COMPANY DISCLOSURE SCHEDULE"), which shall identify exceptions by specific
Section references, or as otherwise described in the SEC Reports (as hereinafter
defined) filed prior the date of this Agreement, the Company hereby represents
and warrants to Parent and Purchaser that:

         SECTION 3.01.  ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.  Each of
the Company and its two direct, wholly owned subsidiaries, Spine-Tech FSC Inc.,
a corporation organized under the laws of Barbados and Spine-Tech Surgical Inc.,
a Minnesota corporation (the "SUBSIDIARIES"), is a corporation duly
incorporated, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has the requisite corporate power and
corporate authority and all necessary governmental approvals to own, lease and
operate its properties and to carry on its business as it is now being
conducted, except where the failure to be so incorporated, existing or in good
standing or to have such power, authority and governmental approvals would not,
individually or in the aggregate, have a Material Adverse Effect (as defined
below).  Each of the Company and the Subsidiaries is duly qualified or licensed
as a foreign corporation to do business, and is in good standing, in each
jurisdiction where the character of the properties owned, leased or operated by
it or the nature of its business makes such qualification or licensing
necessary, except for such failures to be so qualified or licensed and in good
standing which would not, individually or in the aggregate, have a Material
Adverse Effect.  When used in connection with the Company or the Subsidiaries,
the term "MATERIAL ADVERSE EFFECT" means any circumstance, change in or effect
on the Company or any Subsidiary that is, or is reasonably likely to be,
materially adverse to the business, financial condition, results of operations,
assets or liabilities (including, without limitation, contingent liabilities) of
the Company and the Subsidiaries, taken as a whole.  Other than the
Subsidiaries, there are no corporations, partnerships, joint ventures,
associations or other entities in which the Company owns, of record or
beneficially, any direct or indirect equity or similar interest or any right
(contingent or otherwise) to acquire the same.


<PAGE>

                                          11

         SECTION 3.02.  ARTICLES OF INCORPORATION; BY-LAWS.  The Company has
heretofore made available to Parent a complete and correct copy of the Articles
of Incorporation and the By-laws (or equivalent organizational documents), each
as amended to date, of each of the Company and the Subsidiaries.  Such Articles
of Incorporation, By-laws or equivalent organizational documents are in full
force and effect.  Neither the Company nor the Subsidiaries is in violation of
any of the provisions of their respective Articles of Incorporation or By-laws
(or equivalent organizational documents).


         SECTION 3.03.  CAPITALIZATION.  The authorized capital stock of the
Company consists of 15,000,000 shares of Company Common Stock and 5,000,000
shares of preferred stock ("COMPANY PREFERRED STOCK"), of which 300,000 shares
have been designated Series A Junior Participating Preferred Stock, $.01 par
value per share.  As of the date hereof, (i) 10,323,730 Shares are issued and
outstanding, all of which are validly issued, fully paid and nonassessable,
(ii) no Shares are held in the treasury of the Company, (iii) no Shares are held

funds to any person outside the ordinary course of business consistent with past
practice, or to make any investment (in the form of a loan or capital
contribution) in any other person.

         SECTION 3.04.  AUTHORITY RELATIVE TO THIS AGREEMENT.  The Company has
all necessary corporate power and corporate authority to execute and deliver
this Agreement, to perform its obligations hereunder and, subject to approval by
the holders of the Shares at the Shareholders' Meeting (as hereinafter defined)
if so required by law with respect to its obligations to consummate the Merger,
to consummate the transactions contemplated hereby (the "TRANSACTIONS").  The
execution and delivery of this Agreement by the Company and the consummation by
the Company of the Transactions have been duly and validly authorized by all
necessary corporate action, and no other corporate proceedings on the part of
the Company are necessary to authorize this Agreement or to consummate the
Transactions (other than, with respect to the Merger, the approval and adoption
of this Agreement by the holders of a majority of the then outstanding Shares if
and to the extent required by applicable law, and the filing and recordation of
appropriate articles of merger as required by the Minnesota Law).  As an
amplification and not in limitation of the immediately preceding sentence, a
special committee of the Board formed pursuant to Section 302A.673 of the
Minnesota Law has taken all actions required to render inapplicable to the
Transactions the restrictions on business combinations contained in Section
302A.671 and Section 302A.673 of the Minnesota Law.  This Agreement has been
duly and validly executed and delivered by the Company and, assuming the due
authorization, execution and delivery by Parent and Purchaser, constitutes a
legal, valid and binding obligation of the Company.


         SECTION 3.05.  NO CONFLICT; REQUIRED FILINGS AND CONSENTS.  (a)  The
execution and delivery of this Agreement by the Company do not, and the
performance of this Agreement by the Company will not, (i) conflict with or
violate the Articles of Incorporation or By-laws of the Company or equivalent
organizational documents of the Subsidiaries, (ii) assuming that all consents,
approvals, authorizations and other actions described in Section 3.05(b) have
been made and all filings and obligations described in subsection (b) have been
made, conflict with or violate any foreign or domestic law, statute, ordinance,
rule, regulation, order, judgment or decree ("LAW") applicable to the Company or
any Subsidiary or by which any property or asset of the Company or any
Subsidiary is bound, or (iii) result in any breach of or constitute a default
(or an event which with notice or lapse of time or both would become a default)
under, or give to others any right of termination, amendment, acceleration or
cancellation of, or result in the creation of a lien or other encumbrance on any
property or asset of the Company or any Subsidiary pursuant to, any note, bond,
mortgage, indenture, contract, agreement, lease, license, Permit (as hereinafter
defined) or other instrument or agreement, except, with respect to clauses (ii)
and (iii), for any such conflicts, violations, breaches, defaults or other
occurrences which would not, individually or in the aggregate, have a Material
Adverse Effect.


<PAGE>

                                          13

         (b)  The execution and delivery of this Agreement by the Company do
not, and the performance of this Agreement by the Company will not, require any
consent, approval, authorization or permit of, or filing with or notification
to, any governmental or regulatory authority, domestic (local, state or federal)
or foreign ("GOVERNMENTAL AUTHORITY"), except (i) for applicable requirements,
if any, of the Exchange Act, state securities or "blue sky" laws ("BLUE SKY
LAWS"), the National Association of Securities Dealers ("NASD"), state takeover
laws, the pre-merger notification requirements of the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR ACT") and filing and
recordation of appropriate articles of merger as required by the Minnesota Law,
and (ii) where the failure to obtain such consents, approvals, authorizations or
permits, or to make such filings or notifications, would not prevent or delay
consummation of the Offer or the Merger, or otherwise prevent the Company from
performing its obligations under this Agreement, and would not, individually or
in the aggregate, have a Material Adverse Effect.

         SECTION 3.06.  PERMITS; COMPANY PRODUCTS; REGULATION.  (a)  Each of
the Company and each Subsidiary are in possession of all franchises, grants,
authorizations, clearances, licenses, registrations, permits, easements,
variances, exceptions, consents, certificates, approvals and orders of any
Governmental Authority necessary for the Company or each Subsidiary to own,
lease and operate its properties or to carry on its business as it is now being
conducted (the "PERMITS"), except where the failure to have, or the suspension
or cancellation of, any of the Permits would not, individually or in the
aggregate, have a Material Adverse Effect.  As of the date hereof, no suspension
or cancellation of any of the Permits is pending or, to the knowledge of the
Company, threatened, except where the failure to have, or the suspension or
cancellation of, any of the Permits would not, individually or in the aggregate,
have a Material Adverse Effect.  A list of the material Permits is set forth in
Section 3.06(a) of the Company Disclosure Schedule.  Neither the Company nor any
Subsidiary is in conflict with, or in default or violation of, (i) the Foreign
Corrupt Practices Act of 1977, as amended, (ii) any Law applicable to the
Company or any Subsidiary or by which any property or asset of the Company or
any Subsidiary is bound or affected, or (iii) any Permits, except for any such
conflicts, defaults or violations that would not, individually or in the
aggregate, have a Material Adverse Effect.

         (b)  Except as would not have a Material Adverse Effect, since January
1, 1992, there have been no written notices, citations or decisions by any
Governmental Authority that any product produced, manufactured or marketed at
any time by the Company (the "PRODUCTS") is defective or fails to meet any
applicable standards promulgated by such Governmental Authority, and the Company
does not know of any such defect or failure.  Except as would not have a
Material Adverse Effect, the Company has complied with the Law, policies,
procedures and specifications applicable to the Company with respect to the
design, manufacture, labelling, testing and inspection of Products in the United
States and the


<PAGE>

                                          14

operation of manufacturing facilities in the United States promulgated by the
Food and Drug Administration ("FDA"), and has complied with the Law, policies,
procedures and specifications applicable to the Company in any jurisdiction
outside the United States with respect to the design, manufacture, labelling,
testing and inspection of Products and the operation of manufacturing facilities
outside of the United States.  Since January 1, 1992, there have been no
recalls, field notifications or seizures ordered or, to the knowledge of the
Company, threatened by any Governmental Authority with respect to any of the
Products that would, individually or in the aggregate, have a Material Adverse
Effect, and the Company has not independently engaged in such recalls or field
notifications.  The Company has not received any warning letter or Section 305
notices from the FDA.

         (c)  The Company has obtained, in all countries where the Company is
marketing or has marketed its Products, all applicable Permits required to be
obtained by it by Governmental Authorities (including the FDA) in such countries
regulating the safety, effectiveness and market clearance of the Products that
are currently marketed by the Company or its affiliates, except where the
failure to obtain such Permits would not, individually or in the aggregate, have
a Material Adverse Effect.  Section 3.06(c)(i) of the Company Disclosure
Schedule sets forth a list of all licenses, registrations, approvals, permits
and device listings.  Section 3.06(c)(ii) of the Company Disclosure Schedule
sets forth a description of all Company inspections by regulatory authorities,
recalls, product actions and audits since January 1, 1992 and a description of
ongoing clinical studies.

         SECTION 3.07.  SEC FILINGS; FINANCIAL STATEMENTS.  (a)  The Company
has filed all forms, reports and documents required to be filed by it with the
SEC since June 22, 1995 through the date of this Agreement (collectively, the
"SEC REPORTS").  The SEC Reports (i) at the time of their filing complied in all
material respects with the requirements of the Securities Act of 1933, as
amended (the "SECURITIES ACT"), or the Exchange Act, as the case may be, and the
applicable rules and regulations thereunder and (ii) did not, at the time they
were filed, contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary in order to make the
statements made therein, in the light of the circumstances under which they were
made, not misleading.  The Subsidiaries are not required to file any form,
report or other document with the SEC.

         (b)  Each of the financial statements (including, in each case, any
notes thereto) contained in the SEC Reports was prepared in accordance with
United States generally accepted accounting principles ("GAAP") applied on a
consistent basis throughout the periods indicated (except as may be indicated in
the notes thereto), and each fairly presented in all material respects the
financial position, results of operations and cash flows of the Company and its
Subsidiaries, if any, as at the respective dates thereof and for the respective
periods indicated therein, except as otherwise noted therein (subject, in the
case of unaudited


<PAGE>

                                          15

statements, to normal year-end adjustments and except that the unaudited
financial statements do not contain all of the footnote disclosures required by
GAAP).

         (c)  Neither the Company nor any Subsidiary has any liability of any
nature (whether accrued, absolute, contingent or otherwise), except (i)
liabilities and obligations disclosed pursuant to any other representation or
warranty set forth in this Agreement, (ii) debts, liabilities and obligations
set forth in the Company Disclosure Schedule or which, because of the exceptions
set forth in the other representations and warranties contained in this
Agreement, are not required to be disclosed in the Company Disclosure Schedule
in order to avoid a breach of any other representation or warranty contained in
this Agreement, (iii) liabilities and obligations disclosed in any SEC Report
prior to the date hereof, including any Form 10-Q filed since December 31, 1996,
and (iv) other liabilities and obligations which, after giving effect to the
proceeds reasonably expected to be received from any insurance coverage, would
not, individually or in the aggregate, have a Material Adverse Effect.

         (d)  The Company has heretofore furnished to Parent complete and
correct copies of all amendments and modifications that have not been filed by
the Company with the SEC to all agreements, documents and other instruments that
previously had been filed by the Company with the SEC and are currently in
effect.

         SECTION 3.08.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since December
31, 1996, except as contemplated by or as disclosed in this Agreement or as
disclosed in any SEC Report filed since December 31, 1996, the Company and the
Subsidiary have conducted their businesses only in the ordinary course and in a
manner consistent with past practice and, since such date, there has not been
(a), after giving effect to the proceeds reasonably expected to be received from
any insurance coverage, any Material Adverse Effect, (b) any material change by
the Company in its accounting methods, principles or practices, including
without limitation, those used in the calculation of contractual adjustments or
bad debts, (c) any revaluation by the Company of any material assets (including,
without limitation, any writing down of the value of inventory or writing off of
accounts receivable), other than in the ordinary course of business consistent
with past practice, (d) any declaration, setting aside or payment of any
dividend or distribution in respect of the Shares or any redemption, purchase or
other acquisition of any of its securities or (e) any increase in, or
establishment or modification of, any bonus, insurance, severance, deferred
compensation, pension, retirement, profit sharing, stock option (including,
without limitation, the granting of stock options, stock appreciation rights,
performance awards, or restricted stock awards), stock purchase or other
employee benefit plan, or any other increase in the compensation payable or to
become payable to any officers or employees of the Company or any Subsidiary,
except increases in the salaries of employees who are not officers, payment of
profit sharing and bonuses, and


<PAGE>

                                          16

granting of stock options to employees who are not officers in the ordinary
course of business consistent with past practice.

         SECTION 3.09.  ABSENCE OF LITIGATION.  There is no litigation, suit,
claim, action, proceeding or investigation (an "ACTION") pending or, to the
knowledge of the Company, threatened against the Company or any Subsidiary, or
any property or asset of the Company or any Subsidiary, before any court,
arbitrator or Governmental Authority, which (i) individually or in the
aggregate, reasonably would be expected to have a Material Adverse Effect or
(ii) as of the date of this Agreement, seeks to delay or prevent the
consummation of any Transaction.  Neither the Company nor any Subsidiary nor any
property or asset of the Company or any Subsidiary is subject to any continuing
order of, consent decree, settlement agreement or other similar written
agreement with, or, to the knowledge of the Company, continuing investigation
by, any Governmental Authority, or any order, writ, judgment, injunction,
decree, determination or award of any Governmental Authority or arbitrator
having, individually or in the aggregate, a Material Adverse Effect.

         SECTION 3.10.  EMPLOYEE BENEFIT PLANS; LABOR MATTERS.  (a)
Section 3.10 of the Company Disclosure Schedule contains a true and complete
list of all employee benefit plans (within the meaning of Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA")) and all
bonus, stock option, stock purchase, restricted stock, incentive, deferred
compensation, retiree medical or life insurance, supplemental retirement,
severance or other benefit plans, programs or arrangements, and all employment,
termination, severance or other contracts or agreements to which the Company or
any Subsidiary is a party, with respect to which the Company or any Subsidiary
has any obligation or which are maintained, contributed to or sponsored by the
Company or any Subsidiary for the benefit of any current or former employee,
officer or director of the Company or any Subsidiary (collectively, the
"PLANS").  Each Plan is in writing and the Company has previously furnished or
made available to Parent a true and complete copy of each Plan and a true and
complete copy of each material document prepared in connection with each such
Plan, including, without limitation, (i) a copy of each trust or other funding
arrangement, (ii) each summary plan description and summary of material
modifications, (iii) the most recently filed Internal Revenue Service ("IRS")
Form 5500, (iv) the most recently received IRS determination letter for each
such Plan, and (v) the most recently prepared actuarial report and financial
statement in connection with each such Plan.  Neither the Company nor any
Subsidiary has any express or implied commitment (i) to create, incur liability
with respect to or cause to exist any other employee benefit plan, program or
arrangement, (ii) to enter into any contract or agreement to provide
compensation or benefits to any individual or (iii) to modify, change or
terminate any Plan, other than with respect to a modification, change or
termination required by ERISA or the Internal Revenue Code of 1986, as amended
(the "CODE").


<PAGE>

                                          17

         (b)  None of the Plans is a multiemployer plan, within the meaning of
Section 3(37) or 4001(a)(3) of ERISA (a "MULTIEMPLOYER PLAN"), or a single
employer pension plan, within the meaning of Section 4001(a)(15) of ERISA, for
which the Company or any Subsidiary could incur liability under Section 4063 or
4064 of ERISA (a "MULTIPLE EMPLOYER PLAN").  None of the Plans is a "defined
benefit plan" within the meaning of Section 3(35) of ERISA.  Except as disclosed
in Section 3.10 of the Company Disclosure Schedule, none of the Plans
(i) provides for the payment of separation, severance, termination or
similar-type benefits to any person, (ii) obligates the Company or any
Subsidiary to pay separation, severance, termination or other benefits as a
result of any Transaction or (iii) obligates the Company or any Subsidiary to
make any payment or provide any benefit that could be subject to a tax under
Section 4999 of the Code.  None of the Plans provides for or promises retiree
medical, disability or life insurance benefits to any current or former
employee, officer or director of the Company or any Subsidiary, except for
continued healthcare coverage under COBRA.

         (c)  Each Plan which is intended to be qualified under Section 401(a)
of the Code has received a favorable determination letter from the IRS that such
Plan is so qualified, and each trust established in connection with any Plan
which is intended to be exempt from federal income taxation under Section 501(a)
of the Code has received a determination letter from the IRS that such trust is
so exempt.  No fact or event has occurred since the date of any such
determination letter from the IRS that could adversely affect the qualified
status of any such Plan or the exempt status of any such trust.  Each trust
maintained or contributed to by the Company or any Subsidiary which is intended
to be qualified as a voluntary employees' beneficiary association exempt from
federal income taxation under Sections 501(a) and 501(c)(9) of the Code has
received a favorable determination letter from the IRS that it is so qualified
and so exempt, and no fact or event has occurred since the date of such
determination by the IRS that could adversely affect such qualified or exempt
status.

         (d)  There has been no prohibited transaction (within the meaning of
Section 406 of ERISA or Section 4975 of the Code) with respect to any Plan.
Neither the Company nor any Subsidiary is currently liable or has previously
incurred any liability for any tax or penalty arising under Section 4971, 4972,
4979, 4980 or 4980B of the Code or Section 502(c) of ERISA, and no fact or event
exists which could give rise to any such liability.  Neither the Company nor any
Subsidiary has incurred any liability under, or by operation of, Title IV of
ERISA and no fact or event exists which could give rise to any such liability.

         (e)  Each Plan is now and has been operated in all respects in
accordance with the requirements of all applicable laws, including, without
limitation, ERISA and the Code, and the Company and the Subsidiaries have
performed all obligations required to be


<PAGE>

                                          18

performed by them under, and are not in any respect in default under or in
violation of, any Plan.  The audited balance sheet of the Company dated December
31, 1996 reflects an accrual of all amounts of employer contributions and
premiums accrued but unpaid with respect to the Plans.

         (f)  Neither the Company nor any Subsidiary has incurred any liability
under, and have complied in all respects with, the Worker Adjustment Retraining
Notification Act and the regulations promulgated thereunder ("WARN") and do not
reasonably expect to incur any such liability as a result of actions taken or
not taken prior to the Effective Time.

         (g)  (i) There are no claims or actions pending or, to the knowledge
of the Company, threatened between the Company or any Subsidiary and any of
their respective employees, which controversies have a Material Adverse Effect;
(ii) neither the Company nor any Subsidiary is a party to any collective
bargaining agreement or other labor union contract applicable to persons
employed by the Company or any Subsidiary, nor, to the knowledge of the Company,
are there any activities or proceedings of any labor union to organize any such
employees; (iii) neither the Company nor any Subsidiary has breached or
otherwise failed to comply with any provision of any such agreement or contract
and there are no grievances outstanding against the Company or any Subsidiary
under any such agreement or contract; (iv) there are no unfair labor practice
complaints pending against the Company or any Subsidiary before the National
Labor Relations Board or any current union representation questions involving
employees of the Company or any Subsidiary; and (v) there is no strike,
slowdown, work stoppage or lockout, or, to the knowledge of the Company, threat
thereof, by or with respect to any employees of the Company or any Subsidiary.

         SECTION 3.11.  OFFER DOCUMENTS; SCHEDULE 14D-9; PROXY STATEMENT.
Neither the Schedule 14D-9 nor any information supplied by the Company for
inclusion in the Offer Documents shall, at the respective times the
Schedule 14D-9, the Offer Documents or any amendments or supplements thereto are
filed with the SEC or are first published, sent or given to shareholders of the
Company, as the case may be, contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements made therein, in the light of the circumstances
under which they are made, not misleading.  Neither the proxy statement to be
sent to the shareholders of the Company in connection with the Shareholders'
Meeting (as hereinafter defined) nor the information statement to be sent to
such shareholders, as appropriate (such proxy statement or information
statement, as amended or supplemented, being referred to herein as the "PROXY
STATEMENT"), shall, at the date the Proxy Statement (or any amendment or
supplement thereto) is first mailed to shareholders of the Company, contain any
untrue statement of a material fact, or omit to state any material fact required
to be stated therein or necessary in order to make the statements made therein,
in the light of the circumstances under which they are made, not


<PAGE>

                                          19

misleading or shall, at the time of the Shareholders' Meeting or at the
Effective Time, omit to state any material fact necessary to correct any
statement in any earlier communication with respect to the solicitation of
proxies for the Shareholders' Meeting which shall have become false or
misleading.  Notwithstanding the foregoing, no representation or warranty is
made by the Company with respect to statements therein based on information
supplied by Parent or Purchaser or any of their representatives which is
contained in the Schedule 14D-9, the Offer Documents, the Proxy Statement or any
amendment or supplement thereto.  The Schedule 14D-9 and the Proxy Statement
shall comply in all material respects as to form with the requirements of the
Exchange Act and the applicable rules and regulations thereunder.

         SECTION 3.12.  PROPERTY.  The Company and the Subsidiary have
sufficient title to, or right to use, all their tangible properties and assets
necessary to conduct their respective businesses as currently conducted or as
contemplated to be conducted, with only such exceptions as, individually or in
the aggregate, would not interfere with the current use of such property or
asset in such a manner as to have a Material Adverse Effect.

         SECTION 3.13.  INTELLECTUAL PROPERTY.  (a)  Section 3.13(a)(i) of the
Company Disclosure Schedule sets forth a true and complete list and a brief
description of all patents, registered trademarks, registered service marks and
registered copyrights, and all applications therefor, constituting Owned
Intellectual Property (including a complete identification of each patent and
patent application and each registration, certificate or application for
registration thereof, of all Owned Intellectual Property, and for all such Owned
Intellectual Property used by the Company or any Subsidiary in connection with
the development, manufacture, testing, or production of products, or otherwise
used, held or intended to be used in the business of the Company or any
Subsidiary, also lists the name and title of the person or persons responsible
for the creation thereof) and Section 3.13(a)(ii) of the Company Disclosure
Schedule sets forth a true and complete list and a brief description, including
a description of any license, franchise or sublicense thereof, of all Licensed
Intellectual Property, except customary non-negotiated licenses by the Company
as licensee of computer software.  For each registration, certificate or patent
or application for registration or patent listed in Section 3.13(a)(i) of the
Company Disclosure Schedule held by assignment, the assignment has been lawfully
obtained and has been duly recorded with the state or national patent or
trademark office (or such other Governmental Authority as may be necessary under
any law) from which the original patent, certificate or registration issued or
before which the patent application or application for registration is pending.
Except as would not, individually or in the aggregate, have a Material Adverse
Effect, the rights of the Company or any Subsidiary, as the case may be, in or
to the Owned Intellectual Property set forth on Section 3.13(a)(i) of the
Company Disclosure Schedule are held exclusively by the Company or such
Subsidiary, do not conflict with the rights of any other person or entity, and
neither the Company nor any such Subsidiary has received any claim or written
notice from any person or entity to such effect.


<PAGE>

                                          20

         (b)  Except as would not, individually or in the aggregate, have a
Material Adverse Effect, (i) all the Owned Intellectual Property is owned by the
Company or any Subsidiary, free and clear of any encumbrance, (ii) no existing
product of the Company or any Subsidiary or any product of the Company or any
Subsidiary currently in development is being provided, manufactured, sold or
developed in violation of any patents or trademarks, or any other rights of any
person or entity, and (iii) no Actions have been made or asserted or are pending
(nor, to the knowledge of the Company, has any such Action been threatened)
against the Company or any Subsidiary either (A) based upon or challenging or
seeking to deny or restrict the use by the Company or any Subsidiary of any of
the Owned Intellectual Property or the Licensed Intellectual Property or (B)
alleging that any services provided, or products manufactured or sold by the
Company or any Subsidiary are being provided, manufactured or sold in violation
of any patents or trademarks, or any other rights of any person or entity.
Except as would not, individually or in the aggregate, have a Material Adverse
Effect, to the knowledge of the Company, no person or entity is using any
patents, copyrights, trademarks, service marks, trade names, trade secrets or
similar property that are confusingly similar to the Owned Intellectual Property
or, except with respect to customary non-negotiated licenses by the Company as
licensee of computer software, the Licensed Intellectual Property or that
infringe upon the Owned Intellectual Property or, except with respect to
customary non-negotiated licenses by the Company as licensee of computer
software, the Licensed Intellectual Property or upon the rights of the Company
or any Subsidiary therein.  Neither the Company nor any Subsidiary has granted
any license or other right to any other person or entity with respect to the
Owned Intellectual Property or the Licensed Intellectual Property.  Except as
would not, individually or in the aggregate, have a Material Adverse Effect, the
consummation of the Transactions will not result in the termination or
impairment of any of the Owned Intellectual Property or the Licensed
Intellectual Property.

         (c)  To the knowledge of the Company, with respect to all Licensed
Intellectual Property and Owned Intellectual Property, the registered user
provisions of all countries in which the Company or any Subsidiary has obtained
a registered trademark requiring such registrations have been or are in the
process of being complied with in all material respects.

         (d)  The Company has delivered or made available to Parent correct and
complete copies of all licenses, franchises and sublicenses for Licensed
Intellectual Property set forth in Section 3.13(a)(ii) of the Company Disclosure
Schedule and any and all ancillary documents pertaining thereto (including,
without limitation, all amendments, consents and evidence of commencement dates
and expiration dates).  With respect to each of such licenses and sublicenses:


<PAGE>

                                          21

         (i)  such license, franchise or sublicense, together with all
    ancillary documents delivered pursuant to the first sentence of this
    Section 3.13(d), is legal, valid, binding, enforceable and in full force
    and effect and represents the entire agreement between the respective
    licensor and licensee with respect to the subject matter of such license or
    sublicense;

         (ii) such license, franchise or sublicense will not cease to be legal,
    valid, binding, enforceable and in full force and effect on terms identical
    to those currently in effect as a result of the consummation of the
    Transactions, nor will the consummation of the Transactions constitute a
    breach or default under such license, franchise or sublicense;

         (iii)with respect to each such license or sublicense, except as would
    not, individually or in the aggregate, have a Material Adverse Effect:  (A)
    neither the Company nor any Subsidiary has received any notice of
    termination or cancellation under such license or sublicense and no
    licensor or sublicensor has any right of termination or cancellation under
    such license or sublicense prior to the expiration of its term except in
    connection with the default of the Company or any Subsidiary thereunder or
    pursuant to applicable Laws relating to bankruptcy or reorganization, (B)
    neither the Company nor any Subsidiary has received any notice of a breach
    or default under such license or sublicense, which breach or default has
    not been cured, and (C) neither the Company nor any Subsidiary has granted
    to any other person or entity any rights, adverse or otherwise, under such
    license or sublicense; and

         (iv) except as would not, individually or in the aggregate, have a
    Material Adverse Effect, none of the Company, any Subsidiary and, to the
    knowledge of the Company, any other party to such license or sublicense is
    in breach or default of such license or sublicense; and, to the knowledge
    of the Company, no event has occurred that, with notice or lapse of time
    would constitute such a breach or default or permit termination,
    modification or acceleration under such license or sublicense by any party
    thereto (other than the Company or any Subsidiary).

         (e)  The Owned Intellectual Property and the Licensed Intellectual
Property constitutes all Intellectual Property necessary in the conduct of the
business of the Company and the Subsidiaries, and there are no other items of
Intellectual Property that are material to the Company, the Subsidiaries or
their businesses.

         SECTION 3.14.  TAXES.  (a)  The Company and the Subsidiaries have
timely filed all Tax Returns required to be filed by them, or extensions of time

<PAGE>

Effect, and, except as would not, individually or in the aggregate, have a
Material Adverse Effect, such returns and reports are true, complete and
correct.  Except as would not have a Material Adverse Effect, the Company and
the Subsidiaries have paid and discharged within the time and in the manner
prescribed by the law all Taxes that are due and payable, other than such
payments as are being contested in good faith by appropriate proceedings.  The
accruals and reserves for Taxes reflected in the Company's audited consolidated
balance sheet for the fiscal year ended December 31, 1996 are in accordance with
GAAP.  Neither the IRS nor any other taxing authority or agency, domestic or
foreign, is now asserting or, to the knowledge of the Company, threatening to
assert against the Company or any Subsidiary any deficiency or claim for
additional Taxes or interest thereon or penalties in connection therewith.
Except as would not have a Material Adverse Effect, no adjustment relating to
such returns has been proposed in writing by any Tax authority (insofar as
either relates to the activities or income of the Company or any Subsidiary or
could result in liability of the Company or any Subsidiary on the basis of joint
and/or several liability) and, to the knowledge of the Company and the
Subsidiaries, no basis exists for any such adjustment, other than adjustments
which would not, individually or in the aggregate, have a Material Adverse
Effect.  Neither the Company nor any Subsidiary has received a written ruling
from, or entered into a written and legally binding agreement with, a taxing
authority relating to Taxes of the Company or any Subsidiary.  Neither the
Company nor any Subsidiary has granted any waiver of any statute of limitations
with respect to, or any extension of a period for the assessment of, any income
Tax.  The statute of limitations for the assessment of any federal income Taxes
has expired for all income Tax Returns of the Company, or such income Tax
Returns of the Company and the Subsidiaries have been examined by the IRS for
all periods.  There are no Tax liens upon the assets of the Company or any
Subsidiary except for Tax liens that would not, individually or in the
aggregate, have a Material Adverse Effect.  No audits or other administrative
proceeding or court proceedings are presently pending with regard to any Taxes
or Tax Returns of the Company or any Subsidiary.  Neither the Company nor any
Subsidiary is a party to any agreement relating to allocating or sharing of
Taxes which has not been disclosed on its Tax Returns.  No consent under Section
341(f) of the Code has been filed with respect to the Company or any Subsidiary.
Except as would not have a Material Adverse Effect, neither the Company nor any
of its Subsidiaries has a permanent establishment or office or fixed place of
business through which the business of the Company or any of its Subsidiaries is
wholly or partly carried on outside the United States.  Neither the Company nor
any of its Subsidiaries has participated in or cooperated with an international
boycott within the meaning of Section 999 of the Code.

         (b)  "TAX" or "TAXES" means any and all taxes, fees, levies, duties,
tariffs, imposts, and other charges of any kind (together with any and all
interest, penalties, additions to tax and additional amounts imposed with
respect thereto) imposed by any Governmental Authority, including, without

laws of the jurisdiction of its organization and has the requisite corporate
power and corporate authority and all necessary governmental approvals to own,
lease and operate its properties and to carry on its business as it is now being

<PAGE>

                                          28

governmental approvals would not delay consummation of the Transactions, or
otherwise prevent Parent or Purchaser from performing its obligations under this
Agreement.

         SECTION 4.02.  AUTHORITY RELATIVE TO THIS AGREEMENT.  Each of Parent
and Purchaser has all necessary corporate power and corporate authority to
execute and deliver this Agreement, to perform its obligations hereunder and to
consummate the Transactions.  The execution and delivery of this Agreement by
Parent and Purchaser and the consummation by Parent and Purchaser of the
Transactions have been duly and validly authorized by all necessary corporate
action, and no other corporate proceedings on the part of Parent or Purchaser
(including any action by the sole shareholder of Purchaser) are necessary to
authorize this Agreement or to consummate the Transactions (other than, with
respect to the Merger, the filing and recordation of appropriate articles of
merger as required by the Minnesota Law).  This Agreement has been duly and
validly executed and delivered by Parent and Purchaser and, assuming the due
authorization, execution and delivery by the Company, constitutes a legal, valid
and binding obligation of each of Parent and Purchaser enforceable against each
of Parent and Purchaser in accordance with its terms.

         SECTION 4.03.  NO CONFLICT; REQUIRED FILINGS AND CONSENTS.   (a)  The
execution and delivery of this Agreement by Parent and Purchaser do not, and the
performance of this Agreement by Parent and Purchaser will not, (i) conflict
with or violate the Articles of Incorporation or By-laws (or equivalent
organizational documents) of either Parent or Purchaser, (ii) assuming that all
consents, approvals, authorizations and other actions described in Section

or affected, or (iii) result in any breach of or constitute a default (or an
event which with notice or lapse of time or both would become a default) under,
or give to others any rights of termination, amendment, acceleration or
cancellation of, or result in the creation of a lien or other encumbrance on any
property or asset of Parent or Purchaser pursuant to, any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation, except, with respect to clauses (ii) and (iii), for
any such conflicts, violations, breaches, defaults, or other occurrences which
would not prevent or delay consummation of the Transactions, or otherwise
prevent Parent or Purchaser from performing its obligations under this
Agreement.

         (b)  The execution and delivery of this Agreement by Parent and
Purchaser do not, and the performance of this Agreement by Parent and Purchaser
will not, require any consent, approval, authorization or permit of, or filing
with or notification to, any Governmental Authority, except (i) for applicable
requirements, if any, of the Exchange Act, Blue Sky Laws, the NASD, state
takeover laws, the pre-merger notification requirements of the HSR Act and

<PAGE>

                                          29

Minnesota Law and (ii) where the failure to obtain such consents, approvals,
authorizations or permits, or to make such filings or notifications, would not
prevent or delay consummation of the Offer or the Merger, or otherwise prevent
Parent or Purchaser from performing their respective obligations under this
Agreement.

         SECTION 4.04.  OFFER DOCUMENTS; PROXY STATEMENT.  Neither the Offer
Documents nor any information supplied by Parent or Purchaser for inclusion in
the Schedule 14D-9 will, at the time the Offer Documents, the Schedule 14D-9, or

published, sent or given to shareholders of the Company, as the case may be,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
made therein, in the light of the circumstances under which they are made, not
misleading.  The information supplied by Parent for inclusion in the Proxy
Statement will not, on the date the Proxy Statement (or any amendment or
supplement thereto) is first mailed to shareholders of the Company, contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they are made, not misleading, or at the
time of the Shareholders' Meeting or at the Effective Time, omit to state any
material fact necessary to correct any statement in any earlier communication
with respect to the solicitation of proxies for the Shareholders' Meeting which
shall have become false or misleading.  Notwithstanding the foregoing, Parent
and Purchaser make no representation or warranty with respect to any information
supplied by the Company or any of its representatives which is contained in any
of the Offer Documents, the Proxy Statement or any amendment or supplement
thereto.  The Offer Documents shall comply in all material respects as to form
with the requirements of the Exchange Act and the rules and regulations
thereunder.

         SECTION 4.07.  ABSENCE OF LITIGATION.  There is no Action pending or,
to the knowledge of the Parent and Purchaser, threatened against Parent or
Purchaser, or any property or asset of Parent or Purchaser, before any court,
arbitrator or Governmental Authority, which individually or in the aggregate,
reasonably would be expected to delay consummation of the Transactions or
otherwise prevent Parent or Purchaser from performing its obligations under this
Agreement.  Neither Parent nor Purchaser nor any property or asset of Parent or
Purchaser is subject to any continuing order of, consent decree, settlement
agreement or other similar written agreement with, or, to the knowledge of
Parent and Purchaser, continuing investigation by, any Governmental Authority,
or any order, writ, judgment, injunction, decree, determination or award of any
Governmental Authority or arbitrator which, individually or in the aggregate,
would delay consummation of the Transactions or otherwise prevent Parent or
Purchaser from performing its obligations under this Agreement.

         SECTION 4.08.  OWNERSHIP OF COMPANY CAPITAL STOCK.  As of the date of
this Agreement, neither Parent, Purchaser nor any of their affiliates is the
beneficial owner of any shares of capital stock of the Company.

         SECTION 4.09.  BROKERS.  No broker, finder or investment banker (other
than Credit Suisse First Boston Corporation ("CSFB")) is entitled to any
brokerage, finder's or other fee or commission in connection with the
Transactions based upon arrangements made by or on behalf of Parent or
Purchaser.  Parent agrees to pay all such fees and commissions of CSFB.

         SECTION 4.10.  NO IMPLIED REPRESENTATION.  It is the explicit intent
of each party hereto that neither Parent nor Purchaser is making any
representation or warranty whatsoever, express or implied, beyond those given in

Incorporation and By-laws, (i) duly call, give notice of, convene and hold a
special meeting of its shareholders as soon as practicable following
consummation of the Offer for the purpose of considering and taking action on
this Agreement and the Transactions (the "SHAREHOLDERS' MEETING") and

agree, subject to Article VII, to take all necessary and appropriate action to

         SECTION 6.02.  PROXY STATEMENT.  If required by applicable law, as
promptly  as reasonably practicable following consummation of the Offer, the
Company shall file the Proxy Statement with the SEC under the Exchange Act, and
shall use its reasonable efforts to have the Proxy Statement cleared by the SEC.

any requests by the SEC for any amendment or supplement thereto or for
additional information and shall provide to Parent promptly copies of all
correspondence between the Company or any representative of the Company and the
SEC.  The Company shall give Parent and its counsel the reasonable opportunity

give Parent and its counsel the opportunity to review all amendments and
supplements to the Proxy Statement and all responses to requests for additional
information and replies to comments prior to their being filed with, or sent to,
the SEC.  Each of the Company, Parent and Purchaser agrees to use its reasonable
efforts, after consultation with the other parties hereto, to respond promptly
to all such comments of, and requests by, the SEC and to cause the Proxy

         SECTION 6.03.  COMPANY BOARD REPRESENTATION; SECTION 14(f).
(a)  Promptly upon the purchase by Purchaser of Shares pursuant to the Offer
(provided that the Minimum Condition has been satisfied), and from time to time
thereafter, Purchaser shall be entitled, subject to compliance with Section
14(f) of the Exchange Act, to designate up to such number of directors, rounded
down to the next whole number (except where such rounding down would cause
Purchaser to not be entitled to designate at least a majority of directors on
the Board, in which case such number shall be rounded up), on the Board as shall
give Purchaser representation on the Board equal to the product of the total
number of directors on the Board (giving effect to the directors elected
pursuant to this sentence) multiplied by the percentage that the aggregate
number of Shares beneficially owned by Purchaser or any affiliate of Purchaser
following such purchase bears to the total number of Shares then outstanding,
and the Company shall, at such time, promptly take all actions necessary to
cause Purchaser's designees to be elected or appointed as directors of the
Company, including increasing the size of the Board or securing the resignations
of incumbent directors or both.  At such times, the Company shall, upon the
written request of Purchaser, use its reasonable efforts to cause persons
designated by Purchaser to constitute the same percentage as persons designated
by Purchaser shall constitute of the Board of (i) each committee of the Board,
(ii) the board of directors of each Subsidiary and (iii) each committee of each
such board, in each case only to the extent permitted by applicable law.
Notwithstanding anything stated herein, if Shares are purchased pursuant to the
Offer, Parent and Purchaser shall use reasonable efforts to assure


<PAGE>

                                          35

that until the Effective Time, the Board shall have at least one director who is
a director on the date hereof and is not an employee of the Company.

         (b)  The Company shall promptly take all actions required pursuant to
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order
to fulfill its obligations under this Section 6.03 and shall include in the
Schedule 14D-9 such information with respect to the Company and its officers and
directors as is required under Section 14(f) and Rule 14f-1 to fulfill such
obligations.  Parent or Purchaser shall supply to the Company and be solely
responsible for any information with respect to either of them and their
nominees, officers, directors and affiliates required by such Section 14(f) and
Rule 14f-1.

         (c)  Following the election of designees of Purchaser pursuant to 
this Section 6.03, prior to the Effective Time, any amendment of this 
Agreement or the Articles of Incorporation or By-laws of the Company, any 
termination of this Agreement by the Company, any extension by the Company of 
the time for the performance of any of the obligations or other acts of 
Parent or Purchaser or waiver of any of the Company's rights hereunder shall 
require the concurrence of a majority of the directors of the Company then in 
office who neither were designated by Purchaser nor are employees of the 
Company.

         SECTION 6.04.  ACCESS TO INFORMATION; CONFIDENTIALITY.  (a)  From the
date hereof to the Effective Time, upon reasonable notice, the Company shall,
and shall cause the Subsidiary and the officers, directors, employees, auditors
and agents of the Company and the Subsidiary to, afford the officers, employees
and agents of Parent and Purchaser reasonable access during normal business
hours and upon reasonable notice to the officers, employees, agents, properties,
offices and other facilities, books and records of the Company and each
Subsidiary, and shall furnish Parent and Purchaser with all financial, operating
and other data and information as Parent or Purchaser, through its officers,
employees or agents, may reasonably request.  Parent and Purchaser shall make
all reasonable efforts to minimize any disruption to the businesses of the
Company and the Subsidiaries which may result from the requests for data and
information hereunder.

         (b)  All information obtained by Parent or Purchaser pursuant to this
Section 6.04 shall be kept confidential in accordance with the confidentiality
agreement, dated September 25, 1997 (the "CONFIDENTIALITY AGREEMENT"), between
Parent and the Company.

         (c)  No investigation pursuant to this Section 6.04 shall affect any
representation or warranty in this Agreement of any party hereto or any
condition to the obligations of the parties hereto.

                                          36

         SECTION 6.05.  NO SOLICITATION.  (a)  The Company shall, and shall
direct and use all reasonable efforts to cause its officers, directors,
employees, representatives and agents to, immediately cease any discussions or
negotiations with any parties that may be ongoing with respect to any
"acquisition proposal" (as defined in this Section 6.05(a)).  The Company shall
not, nor shall it permit any Subsidiary to, nor shall it authorize or permit any
officer, director or employee of, or any investment banker, accountant, attorney
or other advisor or representative of, the Company or the Subsidiary to,
directly or indirectly, (i) solicit or initiate, or knowingly encourage the
submission of, any acquisition proposal or (ii) participate in any discussions
or negotiations regarding, or furnish to any person any information with respect
to, or take any other action to facilitate the making of any proposal that
constitutes, or may reasonably be expected to lead to, an acquisition proposal;
PROVIDED, HOWEVER, that, if and to the extent that, prior to the acceptance for
payment of Shares pursuant to the Offer, the Board determines in good faith that
it is necessary to do so in accordance with its fiduciary duties to the Company
and its shareholders under applicable law after consultation with its outside
legal counsel, the Company may, in response to a bona fide unsolicited
acquisition proposal, and subject to compliance with Section 6.05(c), (x)
furnish information with respect to the Company and provide access to the person
making such acquisition proposal pursuant to a customary confidentiality
agreement on terms no less favorable to the Company than those contained in the
Confidentiality Agreement and (y) participate in discussions and negotiations
regarding such acquisition proposal.  For purposes of this Agreement,
"ACQUISITION PROPOSAL" means any bona fide proposal or offer from any person
relating to any direct or indirect acquisition of over 20% of any class of
equity securities of the Company or any Subsidiary, any tender offer or exchange
offer that if consummated would result in any person beneficially owning 20% or
more of any class of equity securities of the Company or any Subsidiary, or any
merger, consolidation, business combination, sale of all or a substantial part
of the assets other than in the ordinary course of business, recapitalization,
liquidation, dissolution or similar transaction involving the Company or any
Subsidiary, other than the Transactions.

         (b)  Except as set forth in this Section 6.05, neither the Board nor
any committee thereof shall (i) withdraw or modify, or propose to withdraw or
modify, in a manner adverse to Parent, the approval or recommendation by the
Board or any such committee of the Offer, this Agreement or the Merger, (ii)
approve or recommend, or propose to approve or recommend, any acquisition
proposal or (iii) enter into any agreement with respect to any acquisition
proposal.  Notwithstanding the foregoing, in the event that, prior to the time
of acceptance for payment of Shares pursuant to the Offer, the Board determines
in good faith that it is necessary in accordance with its fiduciary duties to
the Company and its shareholders under applicable law after consultation with
its outside legal counsel to enter into a definitive agreement with respect to a
Superior Proposal, the Board may terminate this Agreement in accordance with
Section 8.01(d)(ii) and concurrently with, or immediately after, such
termination cause the Company to enter into such agreement with respect to such


<PAGE>

                                          37

Superior Proposal and withdraw or modify its approval or recommendation of the
Offer, the Merger or this Agreement.  For purposes of this Agreement, a
"SUPERIOR PROPOSAL" means any bona fide unsolicited proposal made by a third
party to acquire, directly or indirectly, more than 50% of the outstanding
Shares or the shares of capital stock of any surviving corporation in a merger
with the Company on a fully diluted basis or all or substantially all the assets
of the Company and otherwise on terms which the Board determines in its good
faith judgment (after consultation with its financial advisor) to be more
favorable to the Company's shareholders than the Offer and the Merger.

         (c)  In addition to the obligations of the Company set forth in
paragraphs (a) and (b) of this Section 6.05, the Company shall promptly advise
Parent orally and in writing of any request for information or of any
acquisition proposal and the material terms and conditions of such request or
acquisition proposal but need not identify the person making such request or
acquisition proposal.

         (d)  Nothing contained in this Section 6.05 shall prohibit the Company
from taking and disclosing to its shareholders a position contemplated by
Rule 14e-2(a) promulgated under the Exchange Act or from making any disclosure
to the Company's shareholders if the Board determines in good faith that it is
necessary to do so in accordance with its fiduciary duties to the Company and
its shareholders under applicable law after consultation with its outside legal
counsel, PROVIDED, HOWEVER, neither the Company nor the Board nor any committee
thereof shall, except as permitted by Section 6.05(b) or required pursuant to
Rule 14e-2(a) promulgated under the Exchange Act, withdraw or modify, or propose
publicly to withdraw or modify, its position with respect to the Offer, this
Agreement or the Merger or to approve or recommend, or propose publicly to
approve or recommend, an acquisition proposal.

         (e)  The Company agrees not to release any third party from, or waive
any provision of, any confidentiality or standstill agreement to which the
Company is a party.

         SECTION 6.06.  EMPLOYEE STOCK OPTIONS AND OTHER EMPLOYEE BENEFITS.
(a)   The Company shall take all such actions as shall be necessary to cause all
Company Options (including any related alternative rights) granted under the
Company Stock Plans (including those granted to current or former employees,
consultants and directors of the Company or any of its Subsidiaries) (the
"EMPLOYEE STOCK OPTIONS") to become exercisable either prior to the purchase of
the Shares pursuant to the Offer or immediately prior to the Effective Time, as
permitted pursuant to the terms and conditions of the applicable Company Stock
Plan.  The Company shall take all such actions as shall be necessary to cause
all Employee Stock Options that are outstanding immediately prior to the
Effective Time (whether or not then presently exercisable or vested), to be
cancelled.  In exchange for the cancellation of each such


<PAGE>

                                          38

Employee Stock Option (whether or not presently exercisable or vested), the
holder thereof shall be entitled to receive from the Company an amount in cash
equal to the product of the difference between the Per Share Amount and the per
share exercise price of such Employee Stock Option, and the number of shares of
Company Common Stock covered by such Employee Stock Option.  All payments in
respect of such Employee Stock Options shall be made after the Effective Time
and not later than five business days following such time, subject to the
Company's collection of all applicable withholding taxes required by law to be
collected by the Company.  The Company Stock Plans shall be terminated as of the
Effective Time and thereafter the only rights of participants therein shall be
the right to receive the consideration set forth in the previous sentence.
Prior to the Effective Time, the Company shall take action as may be necessary
to carry out the terms of this Section 6.06(a).

         (b)  Section 6.06(b) of the Company Disclosure Schedule contains a
list of each employee of the Company and the Subsidiary who has a written
employment agreement that provides for the payment of severance or similar-type
payments or benefits to such employee following such employee's termination of
employment with the Company and  Subsidiary (the "EMPLOYMENT CONTRACTS").

         (c)  For the period through and including December 31, 1998, Parent
shall, or shall cause the Surviving Corporation to, maintain employee benefit
plans, programs and arrangements which are, in the aggregate, for the employees
as a whole who were active full-time employees of the Company or any Subsidiary
immediately prior to the Effective Time and continue to be active full-time
employees of Purchaser, the Surviving Corporation, any Subsidiary or any other
affiliate of Purchaser, no less favorable than those provided by the Company and
the Subsidiary immediately prior to the Effective Time.  From and after the
Effective Time, for purposes of determining eligibility, vesting and entitlement
to vacation and severance and other benefits for employees actively employed
full-time by the Company or any Subsidiary immediately prior to the Effective
Time under any compensation, severance, welfare, pension, benefit, savings or
other plan of Purchaser or any of its affiliates in which active full-time
employees of the Company and any Subsidiary become eligible to participate
(whether pursuant to this Section 6.06(c) or otherwise), service with the
Company or any Subsidiary (whether before or after the Effective Time) shall be
credited as if such service had been rendered to Purchaser or such affiliate.

         SECTION 6.07.  S&N OPTIONS.  (a) All Company Options (including any
related alternative rights) issued to S&N by the Company (the "S&N OPTIONS")
shall vest, terminate, become exercisable and be cancelled in accordance with
their terms and conditions.  The Company shall take all such actions as shall be
necessary to cause all S&N Options that are outstanding immediately prior to the
Effective Time (whether or not then presently exercisable or vested) to be
cancelled.  In exchange for the cancellation of each S&N Option,


<PAGE>

                                          39

the holder of the S&N Options (whether or not then presently exercisable or
vested) shall be entitled to receive from the Company an amount in cash equal to
the product of the difference between the Per Share Amount and the per share
exercise price of such S&N Option, and the number of shares of Company Common
Stock covered by such S&N Option.  Prior to the Effective Time, the Company
shall take action as may be necessary to carry out the terms of this Section
6.07(a).

         (b)  The Company has provided Parent true and complete copies of the
S&N Options.  Section 6.07(b) of the Company Disclosure Schedule sets forth a
true and complete list of the S&N Options, together with information as to each
S&N Option with respect to date of grant, vesting date, and amount of Company
Common Stock underlying such S&N Option.

         SECTION 6.08.  DIRECTORS' AND OFFICERS' INDEMNIFICATION AND INSURANCE.
(a) The By-laws or Articles of Incorporation of the Surviving Corporation shall
contain provisions no less favorable with respect to indemnification, expense
advancement and exculpation than are set forth in Section 4.01 of the By-laws or
in the Articles of Incorporation of the Company, which provisions shall not be
amended, repealed or otherwise modified for a period of six years from the
Effective Time (or, in the event any claim is asserted within such six year
period, until final disposition of that claim) in any manner that would affect
adversely the rights thereunder of individuals who at the Effective Time or at
any time prior thereto were directors, officers, employees, fiduciaries or
agents of the Company, unless such modification shall be required by Minnesota
Law.  To the extent that the obligations under such provisions are not fully
performed by the Surviving Corporation, Parent agrees to perform fully the
obligations thereunder for the remaining period.

         (b)  Parent or the Surviving Corporation shall use its best efforts to
maintain in effect for a period of not less than six years from the Effective
Time the current directors' and officers' liability insurance policies
maintained by the Company (provided that Parent or the Surviving Corporation may
substitute therefor policies of at least the same coverage containing terms and
conditions which are no less favorable to such directors and officers) with
respect to matters occurring prior to the Effective Time.  Notwithstanding the
foregoing, in no event shall Parent or the Surviving Corporation be required to
expend pursuant to this Section 6.08(b) more than an amount per year equal to
150% of current annual premiums (the "CURRENT PREMIUMS") paid by the Company for
such insurance (which premiums the Company represents and warrants to be
$120,000 in the aggregate); and, PROVIDED, FURTHER, that if the Parent or the
Surviving Corporation is not able to obtain the amount of insurance required by
this Section 6.08(b) for such aggregate premium, Parent or the Surviving
Corporation shall obtain as much insurance as can be obtained for an annual
premium of 150% of the Current Premiums.

         SECTION 6.09.  RIGHTS PLAN.  The Company shall not redeem the Company
Rights prior to the Effective Time unless this Agreement shall have been
terminated pursuant to Article VIII or unless required to do so by order of a
court of competent jurisdiction.  The Board shall take, or cause to be taken,
such action as is necessary to effect the amendments to the Rights Plan as
approved by the Board and described in Section 3.20.

         SECTION 6.10.  NOTIFICATION OF CERTAIN MATTERS.  The Company shall
give prompt notice to Parent, and Parent shall give prompt notice to the
Company, of (i) the occurrence, or non-occurrence, to the extent the Company has
knowledge thereof, of any event the occurrence, or non-occurrence, of which
would cause any representation or warranty contained in this Agreement to be
untrue or inaccurate in any material respect when made provided that no breach
of this covenant shall be deemed to have occurred if the occurrence or
non-occurrence did not result in a breach that had a Material Adverse Effect,
and (ii) any material failure of the Company, Parent or Purchaser, as the case
may be, to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder; PROVIDED, HOWEVER, that the delivery
of any notice pursuant to this Section 6.10 shall not limit or otherwise affect
the remedies available hereunder to the party receiving such notice.

         SECTION 6.11.  FURTHER ACTION; REASONABLE EFFORTS.  (a)  Upon the
terms and subject to the conditions hereof, each of the parties hereto shall
(i) make promptly its respective filings, and thereafter make any other required
submissions, under the HSR Act with respect to the Transactions and (ii) use all
reasonable efforts to take, or cause to be taken, all appropriate action, and to
do, or cause to be done, all things necessary, proper or advisable under
applicable laws and regulations to consummate and make effective the
Transactions, including, without limitation, using its reasonable efforts to
obtain all licenses, permits, consents, approvals, authorizations,
qualifications and orders of governmental authorities and parties to contracts
with the Company and each Subsidiary as are necessary for the consummation of
the Transactions and to fulfill the conditions to the Offer and the Merger.  In
case at any time after the Effective Time any further action is necessary or
desirable to carry out the purposes of this Agreement, the proper officers and
directors of each party to this Agreement shall use their reasonable efforts to
take all such action.

         (b)  Each of the parties hereto agrees to cooperate and use its
reasonable efforts vigorously to contest and resist any action, including
administrative or judicial action, and to have vacated, lifted, reversed or
overturned any decree, judgment, injunction or other order (whether temporary,
preliminary or permanent) (an "ORDER") that is in effect and that restricts,
prevents or prohibits the consummation of the Transactions, including, without
limitation, by vigorously pursuing all available avenues of administrative and
judicial appeal.


<PAGE>

                                          41

         (c)  Each of the parties hereto agrees that the provisions of this
Section shall not interfere with Board's exercise of its fiduciary duties to the
Company and its shareholders as specified in Sections 1.02, 6.01, 6.05 and 8.01.

         SECTION 6.12.  PUBLIC ANNOUNCEMENTS.  Unless otherwise required by
applicable law or stock exchange or NASD requirements applicable to any party
hereto, neither Parent nor the Company shall issue any such press release or
make any such public statement shall with respect to this Agreement or any
Transaction without the consent of the other.  In the event that Parent or the
Company shall be required by applicable law or stock exchange or NASD
requirements to make any such release or statement, it shall first consult the
other.

         SECTION 6.13.  CONFIDENTIALITY AGREEMENT.  The Company hereby waives
the provisions of the Confidentiality Agreement as and to the extent necessary
to permit the consummation of each Transaction.  Upon the acceptance for payment
of Shares pursuant to the Offer, the Confidentiality Agreement shall be deemed
to have terminated without further action by the parties thereto.

         SECTION 7.01.  CONDITIONS TO THE MERGER.  The respective obligations
of each party to effect the Merger shall be subject to the satisfaction at or
prior to the Effective Time of the following conditions:

         (a)  SHAREHOLDER APPROVAL.  This Agreement and the Merger shall have
    been approved and adopted by the affirmative vote of the shareholders of
    the Company to the extent required by the Minnesota Law and the Articles of
    Incorporation of the Company;

         (b)  HSR ACT.  Any waiting period (and any extension thereof)
    applicable to the consummation of the Merger under the HSR Act shall have
    expired or been terminated;

         (c)  NO ORDER.  No foreign, United States or state governmental

<PAGE>

                                          42

    regulation, executive order, decree, injunction or other order (whether
    temporary, preliminary or permanent) which is then in effect and has the
    effect of making the acquisition of Shares by Parent or Purchaser or any
    affiliate of either of them illegal or otherwise restricting, preventing or
    prohibiting consummation of the Offer or Merger; and

         (d)  OFFER.  Purchaser or its permitted assignee shall have purchased
    all Shares validly tendered and not withdrawn pursuant to the Offer;
    PROVIDED, HOWEVER, that the obligation of Parent and Purchaser to effect
    the Merger shall not be conditioned upon this Section 7.01(d) if the
    failure of Purchaser to purchase the Shares pursuant to the Offer shall
    have constituted a breach of the Offer or this Agreement.

                                     ARTICLE VIII

                          TERMINATION, AMENDMENT AND WAIVER

         SECTION 8.01.  TERMINATION.  This Agreement may be terminated and the
Merger and the other Transactions may be abandoned at any time prior to the
Effective Time, notwithstanding any requisite approval and adoption of this
Agreement and the transactions contemplated hereby by the shareholders of the
Company:

         (a)  By mutual written consent of Parent, Purchaser and the Company
    duly authorized by the Boards of Directors of Parent, Purchaser and the
    Company; or

         (b)  By Parent, Purchaser or the Company if (i) the Shares shall not
    have been accepted for payment pursuant to the Offer on or before March 31,
    1998; PROVIDED, HOWEVER, that the right to terminate this Agreement under
    this Section 8.01(b) shall not be available to any party whose failure to
    fulfill any obligation under this Agreement has been the cause of, or
    resulted in, the failure of the Shares to have been accepted for payment on
    or before such date nor be available to Parent or Purchaser unless the

    after consultation with its outside legal counsel in order to enter into a

    prior written notice to Parent, setting forth in reasonable detail the
    final terms and conditions of the Superior Proposal (but the Company shall

    Company shall not theretofore have been required to pay the Fee to Parent
    pursuant to Section 8.03(a)(i), 8.03(a)(ii) or 8.03(a)(iii);

available funds, plus all Expenses (as hereinafter defined).  In no event shall

         (b)  The Company shall, at such time as a Fee is required to be paid,
reimburse each of Parent, Purchaser and their respective stockholders and
affiliates (not later than one business day after submission of statements
therefor) for up to $5,000,000 of actual and documented out-of-pocket expenses

         (c)  Except as set forth in this Section 8.03, all costs and expenses
incurred in connection with this Agreement and the Transactions shall be paid by
the party incurring such expenses, whether or not any Transaction is
consummated.

         (d)  In the event that the Company shall fail to pay the Fee or any
Expenses when due, the term "Expenses" shall be deemed to include the
out-of-pocket costs and expenses actually incurred by Parent and Purchaser
(including, without limitation, fees and


<PAGE>

                                          45

out-of-pocket expenses of counsel) in connection with the collection under and

discretion.  The failure by Parent or Purchaser at any time to exercise any of
the foregoing rights shall not be deemed a waiver of any such right; the waiver
of any such right with respect to particular facts and other circumstances shall
not be deemed a waiver with respect to any other facts and circumstances; and
each such right shall be deemed an ongoing right that may be asserted at any
time and from time to time.
