      On March 22, 1996, InStent entered into a merger agreement with
      Medtronic, Inc., pursuant to which InStent shareholders will receive
      0.3833 shares of Medtronic common stock for each share of InStent common
      stock.  Outstanding options exercisable for InStent common stock will be
      exercisable for Medtronic common stock at the same conversion ratio.  The
      Merger Agreement calls for a pooling of interests transaction.
      Consummation of the Merger is subject to customary conditions, including
      registration with the Securities and Exchange Commission, approval of
      InStent's shareholders and receipt of  Hart-Scott-Rodino approvals.  The
      Company's principal shareholders, directors, executive officers and
      certain of their family members, who in the aggregate own approximately
      38% of the Company's outstanding common stock, have agreed to vote their
      shares for the Merger.  During the three months ended March 31, 1996, the
      Company expensed $245,000 related to this proposed merger.

      Subsequent to the execution of the Merger Agreement, the Company and
      Medtronic also executed a five-year Distribution Agreement, dated as of
      March 27, 1996, pursuant to which the Company appointed Medtronic its
      exclusive worldwide distributor of coronary and carotid stent products.
      This agreement is not contingent upon the consummation of the Merger.

ITEM 2.           MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

     InStent Inc. ("InStent" or the "Company") designs, develops, manufactures
and markets a variety of highly-specialized stents for a broad range of medical
indications.  InStent's stents are designed to hold open passageways in the
body, such as the arterial vasculature, the esophagus, bile duct and male
urethra, that may have closed or become obstructed as a result of aging,
disease or trauma. To date, InStent has focused its product development efforts
on the coronary, vascular, carotid, esophageal, biliary, and urology markets to
treat obstructions due to atherosclerosis, cancerous tumor ingrowth, fibrous
tissue formation, and benign prostatic hypertrophy ("BPH").  InStent believes
these are the primary markets for application of stent technology.  Stents are
increasingly being used as an alternative or adjunct to many surgical and
minimally-invasive procedures or drug therapies.

     InStent's stents include self-expanding, nitinol (nickel-titanium alloy)
wire coils that are inserted into the body non-surgically via InStent's
patented, catheter-based stent delivery systems.  InStent also is developing a
series of balloon expandable stents.  Once placed, stents exert radial force
against the walls of passageways to enable the passageways to remain open and
functional.  InStent manufactures stents with differing flexibilities and
radial forces and in a variety of shapes and sizes to treat specific medical
indications, ranging from relatively rigid esophageal stents that resist tumor
ingrowth to more pliant urethral, coronary and vascular stents that must
conform to delicate and intricate anatomy.  The combination of InStent's stents
and delivery systems enables the accurate, non-surgical placement of a variety
of stents at multiple sites within the body.


RESULTS OF OPERATIONS

     Revenue.  For the first quarter of 1996, revenue increased 138% to
$1,004,000, compared to the first quarter of 1995 revenue of $422,000. The
first quarter increase was due to a 100% increase in unit sales complemented by
a 19% increase in the average selling price.   Two-thirds of the increase in
sales volume was the result of an increase in domestic sales, made possible by
both FDA clearances to market two of the company's products domestically and
the Bard Distribution Agreement.  A change in product mix contributed to the
increased average selling price as sales shifted from the lower priced urology
products to the higher price esophageal and biliary products.

     Gross Profit. Gross margins improved from 61% in the first quarter of 1995
to 65% in the first quarter of 1996. The improved margins were generated by the
higher average selling prices, offset slightly by the change in product mix to
products with a greater average product cost.  The increase in sales volume
resulted in improved production efficiencies causing overall product costs to
decline.

     Operating Expenses.  Operating expenses increased 176% in the first
quarter of 1996, excluding expenses related to the proposed merger, to
$1,911,000, compared to $685,000 in the first quarter of 1995.  Selling,
general and administrative expenses increased 135%, proportionate with the
increase in sales, due to expenses incurred to support the Company's growth as
well as costs associated with being a public company.  Research and development
expenses increased 254% to $889,000 for the first quarter of 1996 due to the
acceleration of new product development, particularly a balloon expandable
stent, and work related to U.S. FDA Investigational Device Exemption
submissions.

     Other Income.  Other income, which consists primarily of interest income,
increased in the first quarter of 1996 to $570,000 from $5,000 for the first
quarter of 1995, due to significantly higher cash and investment balances as a
result of proceeds from the Company's initial public offering which closed on
July 5, 1995.

     Net Loss.  The Company recorded a net loss of  $951,000 in the first
quarter of 1996, compared to a net loss of $423,000 for the first quarter of
1995.  Although the gross margins improved with the increased average selling
prices, the acceleration of new product development and product introductions
were greater, creating a larger loss in the first quarter of 1996 than the
comparable period in 1995, excluding the first quarter 1996 expenses related to
the proposed merger.


LIQUIDITY AND CAPITAL RESOURCES

     Net cash used by operations for the first quarter of 1996 of $1,059,000
was primarily due to the net loss, increase in trade receivables and decrease
in current liabilities.  The Company believes that the net proceeds from its
initial public offering in 1995, and cash flows from current product sales will
be sufficient to fund its operations and planned new product development for
the foreseeable future.

     Capital expenditures of $437,000 for the first quarter were to support
production for the increased sales volume and additional research and
development activities.

     The Company's exposure to foreign currency fluctuations has been limited
to-date since the Company's sales have been denominated in U.S. currency and
because neither of the Company's international subsidiaries have had
significant assets.

     As of March 31, 1996, the Company had no outstanding debt.  Working
capital at the end of the first quarter of 1996 decreased slightly to
$42,055,000 primarily due to the accelerated spending in support of new
products, compared to $1,699,000 at March 31, 1995.


OUTLOOK

     Although the Company currently markets five stents internationally,
to-date only the EsophaCoil esophageal and EndoCoil biliary product lines are
cleared to market in the United States.  The Company will incur substantial
clinical research and other costs in connection with obtaining regulatory
approvals for its products in the United States.  The Company expects to
continue to incur losses until at least such time, if ever, as its products
achieve broader market acceptance internationally and domestically and as it
receives additional regulatory approvals to market a broad line of its products
in the more significant geographic markets.  The Company's longer-term
prospects are highly dependent on successful development, timely receipt of
regulatory approvals and market acceptance of the Company's products.

                      AGREEMENT AND PLAN OF REORGANIZATION


     THIS AGREEMENT is dated as of March 22, 1996, by and among MEDTRONIC,
INC., a Minnesota corporation ("Parent"), BYR ACQUISITION CORP., a Delaware
corporation ("Acquisition Subsidiary"), and InSTENT INC., a Delaware
corporation (the "Company").

     WHEREAS, the Boards of Directors of Parent, Acquisition Subsidiary and the
Company have approved the merger of Acquisition Subsidiary with and into the
Company (the "Merger") upon the terms and subject to the conditions set forth
herein; and

     WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368 of the
Internal Revenue Code of 1986, as amended (the "Code"); and

     WHEREAS, for accounting purposes, it is intended that the Merger shall be
recorded as a "pooling of interests" within the meaning of Accounting
Principles Board Opinion No. 16, and the rules and regulations of the
Securities and Exchange Commission (the "SEC"); and

     WHEREAS, the parties hereto desire to make certain representations,
warranties and agreements in connection with the Merger and also to prescribe
various conditions to the Merger;

     NOW, THEREFORE, in consideration of the foregoing premises and the mutual
representations, warranties, covenants and agreements contained herein, the
parties hereto agree as follows:


                                   ARTICLE 1
                        THE MERGER; CONVERSION OF SHARES

     1.1 The Merger.  Subject to the terms and conditions of this Agreement, at
the Effective Time (as defined in Section 1.2 hereof), Acquisition Subsidiary
shall be merged with and into the Company in accordance with the provisions of
the Delaware General Corporation Law (the "DGCL"), whereupon the separate
corporate existence of Acquisition Subsidiary shall cease, and the Company
shall continue as the surviving corporation (the "Surviving Corporation").
From and after the Effective Time, the Surviving Corporation shall possess all
the rights, privileges, powers and franchises and be subject to all the
restrictions, disabilities and duties of the Company and Acquisition
Subsidiary, all as more fully described in the DGCL.

     1.2 Effective Time.  As soon as practicable after each of the conditions
set forth in Article 6 has been satisfied or waived, the Company and
Acquisition Subsidiary will file, or cause to be filed, with the Secretary of
State of the State of Delaware a Certificate of Merger for the Merger, which
Certificate shall be in the form required by and executed in accordance with
the applicable provisions of the DGCL.  The Merger shall become effective at
the time such filing is made or, if agreed to by Parent and the Company, such
later time or date set forth in the Certificate of Merger (the "Effective
Time").

     1.3 Conversion of Shares.  At the Effective Time, by virtue of the Merger
and without any action on the part of any holder of any share of capital stock
of the Company or Acquisition Subsidiary:

           (a) Each share of common stock of the Company, $.01 par value, (the
      "Company Common Stock") issued and outstanding immediately prior thereto
      (except for the shares referred to in Section 1.3(b) hereof) shall be
      converted into the right to receive 0.3833 of a share (subject to
      adjustment as provided below, the "Conversion Ratio") of common stock of
      Parent, par value $.10 per share, ("Parent Common Stock").

           Notwithstanding the foregoing, if the sum of the number of shares of
      Company Common Stock outstanding immediately prior to the Effective Time
      plus the number of shares subject to then outstanding 

                                     A-5
<PAGE>   6

      options, warrants or other rights to acquire shares of Company Common
      Stock (collectively, "Company Stock Acquisition Rights") is greater than
      10,850,362 such shares or if the aggregate exercise price of all such
      Company Stock Acquisition Rights then outstanding is less than the
      aggregate exercise price reflected in Schedule 3.3, then the Conversion
      Ratio shall be the lower of 0.3833 and the amount (rounded to the nearest
      ten thousandth, with the fourth decimal place rounded up if the fifth
      decimal place is 5 or more) equal to (i) $[23.00 times 10,850,362] minus
      the aggregate exercise price reflected in Schedule 3.3 plus the aggregate
      amount received by the Company as a result of any issuance of Company
      Common Stock after the date of this Agreement and prior to the Effective
      Time plus the aggregate exercise price of all Company Stock Acquisition
      Rights outstanding immediately prior to the Effective Time divided by
      (ii) $60.00 times the sum of (A) the number of shares of Company Common
      Stock outstanding immediately prior to the Effective Time plus (B) the
      number of shares subject to Company Stock Acquisition Rights then
      outstanding.

           An appropriate adjustment shall be made in the event that, prior to
      the Effective Time, the outstanding shares of Company Common Stock,
      without new consideration, are changed into or exchanged for a different
      kind of shares or securities through a reorganization, reclassification,
      stock dividend, stock combination or other like change in the Company's
      capitalization.  Notwithstanding the foregoing, nothing in this Section
      shall be deemed to constitute authorization or permission for or consent
      from Parent or Acquisition Subsidiary to any increase in the number of
      shares of Company Common Stock outstanding or subject to outstanding
      Company Stock Acquisition Rights, to any decrease in the exercise price
      of such Rights or to any reorganization, reclassification, stock
      dividend, stock combination or other like change in capitalization.

           (b) Each share of Company Common Stock issued and outstanding
      immediately prior to the Effective Time that is held in the treasury of
      the Company or is then owned beneficially or of record by Parent,
      Acquisition Subsidiary or any direct or indirect subsidiary of Parent or
      the Company shall be cancelled without payment of any consideration
      therefor and without any conversion thereof.

           (c) Each share of any other class of capital stock of the Company
      (other than Company Common Stock) shall be cancelled without payment of
      any consideration therefor and without any conversion thereof.

           (d) Each share of common stock of Acquisition Subsidiary, par value
      $.01 per share, (the "Acquisition Subsidiary Common Stock") issued and
      outstanding immediately prior to the Effective Time shall be converted
      into one share of the common stock of the Surviving Corporation, $.01 par
      value, (the "Surviving Corporation Common Stock").

      1.4 Dissenting Shares.  The Merger does not give rise to appraisal rights
 of the Company shareholders.
 
      1.5 Exchange of Company Common Stock.

           (a) Promptly after the Effective Time, Parent shall cause Parent's
      stock transfer agent or such other person as Parent may appoint to act as
      exchange agent (the "Exchange Agent") to mail to each holder of record
      (other than Parent, Acquisition Subsidiary, the Company or any subsidiary
      of Parent or the Company) of a certificate or certificates that
      immediately prior to the Effective Time represented outstanding shares of
      Company Common Stock ("Company Certificates") a form letter of
      transmittal (which shall specify that delivery shall be effective, and
      risk of loss and title to Company Certificate(s) shall pass, only upon
      delivery of Company Certificate(s) to the Exchange Agent) and
      instructions for such holder's use in effecting the surrender of Company
      Certificates in exchange for certificates representing shares of Parent
      Common Stock.

           (b) As soon as practicable after the Effective Time, the Exchange
      Agent shall distribute to holders of shares of Company Common Stock, upon
      surrender to the Exchange Agent of one or more Company Certificates for
      cancellation, together with a duly-executed letter of transmittal, (i)
      one or more Parent certificates representing the number of whole shares
      of Parent Common Stock into which the shares 

                                     A-6
<PAGE>   7

      represented by Company Certificate(s) shall have been converted pursuant
      to Section 1.3(a), and (ii) a bank check in the amount of cash into which
      the shares represented by Company Certificate(s) shall have been
      converted pursuant to Section 1.5(f) (relating to fractional shares), and
      Company Certificate(s) so surrendered shall be cancelled.  In the event
      of a transfer of ownership of Company Common Stock that is not registered
      in the transfer records of the Company, it shall be a condition to the
      issuance of shares of Parent Common Stock that Company Certificate(s) so
      surrendered shall be properly endorsed or be otherwise in proper form for
      transfer and that such transferee shall (i) pay to the Exchange Agent any
      transfer or other taxes required, or (ii) establish to the satisfaction
      of the Exchange Agent that such tax has been paid or is not payable.

           (c) Holders of Company Common Stock will be entitled to any
      dividends or other distributions pertaining to the Parent Common Stock
      received in exchange therefor that become payable to persons who are
      holders of record of Parent Common Stock as of a record date that follows
      the Effective Time, but only after they have surrendered their Company
      Certificates for exchange.  Subject to the effect, if any, of applicable
      law, the Exchange Agent shall receive, hold, and remit any such dividends
      or other distributions to each such record holder entitled thereto,
      without interest, at the time that such Company Certificates are
      surrendered to the Exchange Agent for exchange.  Holders of Company
      Common Stock will not be entitled, however, to dividends or other
      distributions that become payable before or after the Effective Time to
      persons who were holders of record of Parent Common Stock as of a record
      date that is prior to the Effective Time.

           (d) All shares of Parent Common Stock issued upon the surrender for
      exchange of Company Common Stock in accordance with the terms hereof
      (including any cash paid for fractional shares pursuant to Section 1.5(f)
      hereof) shall be deemed to have been issued in full satisfaction of all
      rights pertaining to such shares of Company Common Stock.

           (e) After the Effective Time, there shall be no further registration
      of transfers on the stock transfer books of the Surviving Corporation of
      the shares of Company Common Stock that were outstanding immediately
      prior to the Effective Time.  If, after the Effective Time, Company
      Certificates representing such shares are presented to the Surviving
      Corporation, they shall be cancelled and exchanged as provided in this
      Article 1.  As of the Effective Time, the holders of Company Certificates
      representing shares of Company Common Stock shall cease to have any
      rights as shareholders of the Company, except such rights, if any, as
      they may have pursuant to the DGCL.  Except as provided above, until such
      Company Certificates are surrendered for exchange, each such Company
      Certificate shall, after the Effective Time, represent for all purposes
      only the right to receive the number of whole shares of Parent Common
      Stock into which the shares of Company Common Stock shall have been
      converted by the Merger as provided in Section 1.3(a) hereof and the
      right to receive the cash value of any fraction of a share of Parent
      Common Stock as provided in Section 1.5(f) hereof.

           (f) No fractional shares of Parent Common Stock and no certificates
      or scrip therefor, or other evidence of ownership thereof, shall be
      issued upon the surrender for exchange of Company Certificates, no
      dividend or other distribution of Parent shall relate to any fractional
      share, and such fractional share interests shall not entitle the owner
      thereof to vote or to any rights of a shareholder of Parent.  All
      fractional shares of Parent Common Stock to which a holder of Company
      Common Stock immediately prior to the Effective Time would otherwise be
      entitled, at the Effective Time, shall be aggregated if and to the extent
      multiple Company Certificates of such holder are submitted together to
      the Exchange Agent.  If a fractional share results from such aggregation,
      then (in lieu of such fractional share) the Exchange Agent shall pay to
      each holder of shares of Company Common Stock who otherwise would be
      entitled to receive such fractional share of Parent Common Stock an
      amount of cash (without interest) determined by multiplying (i) the
      Parent Average Market Price (defined below) by (ii) the fractional share
      of Parent Common Stock to which such holder would otherwise be entitled.
      Parent will make available to the Exchange Agent any cash necessary for
      this purpose.  For purposes hereof, "Parent Average Market Price" shall
      mean the average (rounded to the nearest full cent, with the cents
      rounded up if the third decimal place is 5 or more) of the closing sale
      prices of a share of Parent Common Stock as reported on the New York
      Stock Exchange (the "NYSE") Composite Tape, as reported in The Wall
      Street Journal, for 

                                     A-7
<PAGE>   8

      the twenty consecutive NYSE trading days ending and including the
      fifth NYSE trading day immediately preceding the Effective Time.

           (g) In the event any Company Certificates shall have been lost,
      stolen or destroyed, the Exchange Agent shall issue in exchange for such
      lost, stolen or destroyed Company Certificate, upon the making of an
      affidavit of that fact by the holder thereof, such shares of Parent
      Common Stock and cash for fractional shares, if any, as may be required
      pursuant to this Article 1; provided, however, that Parent may,
      in its discretion and as a condition precedent to the issuance thereof,
      require the owner of such lost, stolen or destroyed Company Certificate
      to deliver a bond in such sum as Parent may direct as indemnity against
      any claim that may be made against Parent or the Exchange Agent with
      respect to such Company Certificate alleged to have been lost, stolen or
      destroyed.

           (h) Each person entitled to receive shares of Parent Common Stock
      pursuant to this Article 1 shall receive together with such shares the
      number of Parent Common Stock Purchase Rights (pursuant to the Rights
      Agreement dated as of June 27, 1991, between Parent and Norwest Bank
      Minnesota, N.A., the "Parent Rights Plan") per share of Parent Common
      Stock equal to the number of Parent Common Stock Purchase Rights
      associated with one share of Parent Common Stock at the Effective Time.

     1.6 Exchange of Acquisition Subsidiary Common Stock.  From and after the
Effective Time, each outstanding certificate previously representing shares of
Acquisition Subsidiary Common Stock shall be deemed for all purposes to
evidence ownership of and to represent the number of shares of Surviving
Corporation Common Stock into which such shares of Acquisition Subsidiary
Common Stock shall have been converted.  Promptly after the Effective Time, the
Surviving Corporation shall issue to Parent a stock certificate or certificates
representing such shares of Surviving Corporation Common Stock in exchange for
the certificate or certificates that formerly represented shares of Acquisition
Subsidiary Common Stock, which shall be cancelled.

     1.7 Stock Options. Each option to purchase shares of Company Common Stock
that is outstanding at the Effective Time (a "Company Option") shall, by virtue
of the Merger and without any action on the part of the holder thereof, be
assumed by Parent in such manner that Parent (i) is a corporation "assuming a
stock option in a transaction to which Section 424(a) applies" within the
meaning of Section 424 of the Code and the regulations thereunder or (ii) to
the extent that Section 424 of the Code does not apply to any such Company
Option, would be such a corporation were Section 424 of the Code applicable to
such Company Option.  From and after the Effective Time, all references to the
Company in the Company Option shall be deemed to refer to Parent.  The Company
Option assumed by Parent shall be exercisable upon the same terms and
conditions as under the Company Option except that (i) such Company Option
shall entitle the holder to purchase from Parent the number of shares of Parent
Common Stock (rounded down to the nearest whole number of such shares) that
equals the product of the Conversion Ratio times the number of shares of
Company Common Stock subject to such option immediately prior to the Effective
Time and (ii) the option exercise price per share of Parent Common Stock shall
be an amount (rounded up to the nearest full cent) equal to the option exercise
price per share of Company Common Stock in effect immediately prior to the
Effective Time divided by the Conversion Ratio.  As promptly as practicable
after the Effective Time, Parent shall issue to each holder of a Company Option
a written instrument informing such holder of the assumption by Parent of such
Company Option.

     1.8 Capitalization Changes.  If, between the date of this Agreement and
the Effective Time, the outstanding shares of Parent Common Stock shall have
been changed into a different number of shares or a different class by reason
of any reclassification, recapitalization, split-up, combination, exchange of
shares, or stock dividend, the Conversion Ratio and all per share price amounts
and calculations set forth in this Agreement shall be appropriately adjusted.

     1.9 Certificate of Incorporation of the Surviving Corporation.  The
Certificate of Incorporation of Acquisition Subsidiary, as in effect
immediately prior to the Effective Time, shall be the Certificate of
Incorporation of the Surviving Corporation until thereafter amended in
accordance with applicable law; provided that upon the Effective Time, Article
I of the Certificate of Incorporation of the Surviving Corporation shall be
amended to read in its entirety as follows:  "The name of the Corporation is
[Buyer][Global], Inc."

                                     A-8

<PAGE>   9


     1.10 Bylaws of the Surviving Corporation.  The Bylaws of Acquisition
Subsidiary, as in effect immediately prior to the Effective Time, shall be the
Bylaws of the Surviving Corporation until thereafter amended in accordance with
applicable law.

     1.11 Directors and Officers of the Surviving Corporation.  The directors
and officers of Acquisition Subsidiary immediately prior to the Effective Time
shall be the directors and officers, respectively, of the Surviving Corporation
until their respective successors shall be duly elected and qualified.

                                    CLOSING

                                   ARTICLE 3
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company hereby makes the following representations and warranties to
Parent and Acquisition Subsidiary:

     3.1 Organization.  The Company and each subsidiary of the Company
(referred to herein as a "Subsidiary") is a corporation duly organized, validly
existing and in good standing under the laws of its respective jurisdiction of
incorporation and has all requisite corporate power and authority to own, lease
and operate its properties and to carry on its business as now being conducted.
The Company and each Subsidiary is duly qualified and in good standing to do
business in each jurisdiction in which the property owned, leased or operated
by it or the nature of the business conducted by it makes such qualification
necessary and where the failure to qualify would have a Company Material
Adverse Effect (as defined below).  "Company Material Adverse Effect" means an
effect that, individually or in the aggregate with other effects, is or would
reasonably be expected to be materially adverse:  (i) to the present or planned
business, properties, liabilities, results of operation or financial condition
of the Company and its Subsidiaries, considered as a whole; (ii) to the ability
of Parent or the Surviving Corporation to conduct such businesses, as presently
conducted, following the Effective Time; or (iii) to the Company's ability to
perform any of its obligations under this Agreement or to consummate the
Merger.  The jurisdictions in which the Company and each Subsidiary are
qualified are listed on SCHEDULE 3.1.  The Company has heretofore delivered to
Parent complete and accurate copies of the Certificate of Incorporation and
Bylaws of the Company and each Subsidiary, as currently in effect.  Except to
the extent specifically disclosed on SCHEDULE 3.1, neither the Company nor any
Subsidiary, directly or indirectly, owns or controls or has any capital,
equity, partnership, participation or other ownership interest in any
corporation, partnership, joint venture or other business association or
entity.

     3.2 Authorization.  The Company has full corporate power and authority to
execute and deliver this Agreement and, subject to obtaining the necessary
approval of its shareholders, to consummate the transactions contemplated
hereby, and to file and distribute the Proxy Statement/Prospectus (as defined
in Section 5.4 hereof).  The execution and delivery of this Agreement by the
Company and the consummation of the transactions contemplated hereby have been
duly and validly authorized and approved by the Company's Board of Directors,

                                     A-9



<PAGE>   10

no other corporate proceedings on the part of the Company or any Subsidiary are
necessary to authorize this Agreement, and, subject to obtaining the approval
of its shareholders, no other corporate action on the part of the Company or
any Subsidiary is necessary to consummate the transactions contemplated hereby.
This Agreement has been duly and validly executed and delivered by the Company
and constitutes the valid and binding obligation of the Company, enforceable in
accordance with its terms, subject to laws of general application relating to
bankruptcy, insolvency and the relief of debtors and rules of law governing
specific performance, injunctive relief or other equitable remedies.  To the
Company's knowledge, each Agreement to Facilitate Merger and Affiliate's Letter
(as described in Sections 5.11 and 5.6) has been duly and validly executed and
delivered by the Company shareholder who is a party thereto and constitutes the
valid and binding obligation of such shareholder, enforceable in accordance
with its terms, subject to laws of general application relating to bankruptcy,
insolvency and the relief of debtors and rules of law governing specific
performance, injunctive relief or other equitable remedies.

     3.3 Capitalization.  The authorized capital stock of the Company consists
of (i) 25,000,000 shares of Company Common Stock, $.01 par value, of which
10,024,693 shares are issued and outstanding and no shares are held in the
Company's treasury, and (ii) 3,000,000 shares of the Company Preferred Stock,
$.01 par value, none of which are issued or outstanding.  Except as set forth
on SCHEDULE 3.3, all issued and outstanding shares of capital stock of each
Subsidiary are owned, beneficially and of record, by the Company, free and
clear of any Liens (as defined in Section 3.14).  All issued and outstanding
shares of Company Common Stock have been validly issued, are fully paid and
nonassessable, and have not been issued in violation of and are not currently
subject to any preemptive rights.  Except for options to purchase an aggregate
825,669 shares of Company Common Stock granted pursuant to the Company 1993
Stock Option Plan and the 1995 Stock Option and Compensation Plan, (the
"Company Option Plans"), there are not any outstanding or authorized
subscriptions, options, warrants, calls, rights, convertible securities,
commitments, restrictions, arrangements or any other agreements of any
character to which the Company or any Subsidiary is a party that, directly or
indirectly, (i) obligate the Company or any Subsidiary to issue any shares of
capital stock or any securities convertible into, or exercisable or
exchangeable for, or evidencing the right to subscribe for, any shares of
capital stock, (ii) call for or relate to the sale, pledge, transfer or other
disposition or encumbrance by the Company or any Subsidiary of any shares of
its capital stock, or (iii) to the knowledge of the Company, relate to the
voting or control of such capital stock.  To the Company's knowledge, except as
specifically disclosed on SCHEDULE 3.3, no shares of Company Common Stock
beneficially owned by an affiliate of the Company are subject to a pledge,
security interest or other security agreement or arrangement.  SCHEDULE 3.3
sets forth a complete and accurate list of all stock options, warrants and
other rights to acquire Company Common Stock, including the name of the holder,
the date of grant, acquisition price, expiration date, number of shares,
exercisability schedule, and, in the case of options, the type of option under
the Code.  SCHEDULE 3.3 also sets forth the restrictions to which any shares of
Company Common Stock issued pursuant to the Company Option Plans or otherwise
are currently subject and also sets forth the restrictions to which such shares
will be subject immediately after the Effective Time.  Section 1.7 hereof is
consistent with the terms and provisions of the Company Option Plans, and no
consent of holders or participants under such Plans is required to carry out
the provisions of such Section.

     3.4 Reports and Financial Statements.  The Company has filed all forms,
reports, registration statements and documents required to be filed by it with
the Securities and Exchange Commission ("SEC") since January 1, 1995 (such
forms, reports, registration statements and documents, together with any
amendments thereto, are referred to as the "Company SEC Filings").  As of their
respective dates, the Company SEC Filings (i) complied as to form in all
material respects with the applicable requirements of the Securities Act of
1933 and the rules and regulations thereunder (the "1933 Act") and the
Securities Exchange Act of 1934 and the rules and regulations thereunder (the
"1934 Act"), as the case may be, and (ii) did not contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements made therein, in light of the
circumstances under which they were made, not misleading.  The audited
financial statements and unaudited interim financial statements included or
incorporated by reference in the Company SEC Filings and the Company's audited
financial statements at and for the year ended December 31, 1995 (the "Company
1995 Financials") (i) were prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the periods involved
(except as may be indicated therein or in the notes thereto), (ii) complied as
of their respective dates in all material respects with applicable accounting
requirements and the published rules and regulations of the SEC with respect
thereto, and (iii) fairly present, in all material respects, the consolidated

                                    A-10



<PAGE>   11


financial position of the Company as of the dates thereof and the income, cash
flows and changes in shareholder's equity for the periods involved.  The
statements of operations included in the audited or unaudited interim financial
statements in the Company SEC Filings and in the 1995 Financials do not contain
any items of special or nonrecurring income or any other income not earned in
the ordinary course of business, except as expressly specified in the
applicable statement of operations or notes thereto.  Prior to the date hereof,
the Company has delivered to Parent complete and accurate copies of all the
Company SEC Filings since January 1, 1995 and of the Company 1995 Financials
and has also delivered to Parent complete and accurate copies of all statements
on Schedule 13D and Schedule 13G known to the Company to have been filed with
the SEC with respect to capital stock of the Company.  The Company has filed in
a timely manner all reports required to be filed by it pursuant to Sections 13,
14 or 15(d) of the 1934 Act.

     3.5 Absence of Undisclosed Liabilities.  Except to the extent specifically
disclosed on SCHEDULE 3.5, neither the Company nor any Subsidiary has any
liabilities or obligations of any nature (whether absolute, accrued, contingent
or otherwise) except (a) liabilities or obligations that are accrued or
reserved against in the audited consolidated balance sheet of the Company as of
December 31, 1995 contained in the Company 1995 Financials (the "Company
Audited Balance Sheet"), and (b) liabilities or obligations arising since
December 31, 1995 in the ordinary course of business and consistent
with past practice that would not have a Company Material Adverse Effect.

     3.6 Consents and Approvals.  Except for (i) any applicable requirements of
the 1933 Act, the 1934 Act, state securities laws, the Hart-Scott-Rodino
Antitrust Improvements Act of 1976 and the regulations thereunder (the "HSR
Act"), and the antitrust, competition, foreign investment or similar laws of
any foreign countries or supranational commissions or boards that require
pre-merger notifications or filings with respect to the Merger (collectively,
"Foreign Merger Laws"), (ii) the Company shareholders' approval, (iii) the
filing and recordation of appropriate merger documents as required by the DGCL,
and (iv) any items disclosed on SCHEDULE 3.6, the execution and delivery of
this Agreement by the Company, and, to the Company's knowledge, the execution
and delivery of the Agreements to Facilitate Merger, and the consummation of
the transactions contemplated hereby and thereby will not: (a) violate any
provision of the Certificate of Incorporation or Bylaws of the Company or any
Subsidiary; (b) violate any statute, rule, regulation, order or decree of any
federal, state, local or foreign body or authority (including, but not limited
to, the Food and Drug Administration (the "FDA") or any nongovernmental
self-regulatory agency) by which the Company or any Subsidiary or any of their
respective properties or assets may be bound; (c) require any filing with or
permit, consent or approval of any federal, state, local or foreign public body
or authority (including, but not limited to, the FDA or any nongovernmental
self-regulatory agency); or (d) result in any violation or breach of, or
constitute (with or without due notice or lapse of time or both) a default
under, result in the loss of any material benefit under, or give rise to any
right of termination, cancellation, increased payments or acceleration under,
or result in the creation of any Lien (as defined in Section 3.14) on any of
the properties or assets of the Company or any Subsidiary under, any of the
terms, conditions or provisions of any note, bond, mortgage, indenture,
license, franchise, permit, authorization, agreement or other instrument or
obligation to which the Company or any Subsidiary is a party, or by which it or
any of its properties or assets may be bound, except, in the case of clause
(d), for any such violations, breaches, defaults or other occurrences which
would not prevent or delay consummation of any of the transactions contemplated
hereby in any material respect, or otherwise prevent the Company from
performing its obligations under this Agreement in any material respect, and
would not have a Company Material Adverse Effect.

     3.7 Compliance with Laws.  All activities of the Company and each
Subsidiary have been, and are currently being, conducted in compliance with all
applicable federal, state, local or foreign laws, ordinances, regulations,
interpretations, judgments, decrees, injunctions, permits, licenses,
certificates, governmental requirements, orders and other similar items of any
court or other governmental entity (including, but not limited to, those of the
FDA or any nongovernmental self-regulatory agency), the failure to comply with
which would have a Company Material Adverse Effect.  The Company and each
Subsidiary has timely filed or otherwise provided all registrations, reports,
data, and other information and applications with respect to its medical
device, pharmaceutical, consumer, health-care and other governmentally
regulated products (the "Regulated Products") required to be filed with or
otherwise provided to the FDA or any other federal, state, local or foreign
governmental authorities with jurisdiction over the manufacture, use or sale of
the Regulated Products, and all regulatory licenses 

                                    A-11


<PAGE>   12


or approvals in respect thereof are in full force and effect, except where the
failure to file timely such registrations, reports, data, information and
applications or the failure to have such licenses and approvals in full force
and effect would not have a Company Material Adverse Effect.

     3.8 Litigation.  Except to the extent specifically disclosed on SCHEDULE
3.8, to the Company's knowledge, no investigation or review by any federal,
state, local or foreign body or authority (including, but not limited to, the
FDA or any nongovernmental self-regulatory agency) with respect to the Company
or any Subsidiary is pending or threatened, nor has any such body or authority
(including, but not limited to, the FDA or any nongovernmental self-regulatory
agency) indicated to the Company or any Subsidiary an intention to conduct the
same.  Except to the extent specifically disclosed on SCHEDULE 3.8, there are
no claims, actions, suits or proceedings by any private party that could
reasonably be expected to involve individually an amount in excess of $25,000
or collectively an aggregate amount in excess of $100,000, or by any
governmental body or authority (including, but not limited to, the FDA or any
nongovernmental self-regulatory agency), against or affecting the Company or
any Subsidiary, pending or, to the knowledge of the Company, threatened at law
or in equity, or before any federal, state, local, foreign or other
governmental department, commission, board, bureau, agency or instrumentality
(including, but not limited to, the FDA or any nongovernmental self-regulatory
agency) and, to the knowledge of the Company, there is no basis for any such
investigation, review, claim, action, suit or proceeding that would have a
Company Material Adverse Effect.

     3.9 Absence of Material Adverse Changes.  Except to the extent
specifically disclosed on SCHEDULE 3.9, since December 31, 1995 there has not
been any (a) change or circumstance that would have a Company Material Adverse
Effect; (b) action by the Company or any Subsidiary that, if taken on or after
the date of this Agreement, would require the consent or approval of Parent

approval has been given as provided therein; (c) damage, destruction or loss,
whether covered by insurance or not, that would have a Company Material Adverse
Effect; (d) change by the Company or any Subsidiary in accounting methods or
principles used for financial reporting purposes, except as required by a
change in generally accepted accounting principles and concurred with by the
Company's independent public accountants; or (e) agreement, whether in writing
or otherwise, to take any action described or referenced in this Section 3.9.

     3.10 Environmental Laws and Regulations.  SCHEDULE 3.10 completely and
accurately sets forth the following: (a) a list of, to the Company's knowledge,
all above-ground storage tanks or underground storage tanks for Hazardous
Materials (as defined below) on real property now or at any time in the past
owned, leased or occupied by the Company or any Subsidiary (such real property
referred to in this Section as the "Real Property"); (b) the identity of any
Hazardous Materials (as defined below) used, generated, transported or disposed
of by the Company or any Subsidiary now or at any time in the past, together

     The Company and each Subsidiary have obtained, and maintained in full
force and effect, all required environmental permits and other governmental
approvals and are in compliance with all applicable Regulations (as defined
below), except where the failure to so obtain and maintain or to be in
compliance would not have a Company Material Adverse Effect.  Neither the
Company nor any Subsidiary (i) has received a written notice or Claim (as
defined below) alleging potential liability under any of the Regulations or
alleging a violation of the Regulations or (ii) has any knowledge that such a
notice or Claim may be issued in the future.  Neither the Company nor any
Subsidiary has any knowledge of any notices to or Claims against any persons,
or reasonable basis therefor, alleging potential liability under any of the
Regulations with respect to the Real Property or any adjoining properties or
which could reasonably be expected to affect the Real Property.  Neither the
Company nor any Subsidiary (i) has been or is presently subject to or, to the
knowledge of the Company, threatened with any administrative or judicial
proceeding pursuant to the Regulations, or (ii) has any information that it may
be subject

<PAGE>   13

to or, to the knowledge of the Company, threatened with such a
proceeding in the future.  Neither the Company nor any Subsidiary has knowledge
of any conditions or circumstances that could reasonably be expected to result
in the determination of liability against the Company or any Subsidiary
relating to environmental matters that would have a Company Material Adverse
Effect, including, but not limited to, any Claim arising from past or present
environmental practices with respect to Hazardous Materials, the Real Property
or to any disposal sites.  No Hazardous Materials have been or are threatened
to be discharged, omitted or released into the air, water, soil, or subsurface
at or from any Real Property by the Company or, to the Company's knowledge, by
any other person.

any Subsidiary.

     3.11 Officers, Directors and Employees.  Prior to the date hereof, the
Company has provided to Parent a list that completely and accurately sets forth
the name and current annual salary rate of each officer or employee of the
Company or any Subsidiary whose total remuneration for the last fiscal year

or any Subsidiary.  There is no labor dispute pending or, to the knowledge of
the Company, threatened between the Company or any Subsidiary and its
employees.

     3.12 Taxes.  The Company has previously furnished to Parent complete and
accurate copies of all tax or assessment reports and tax returns (including any
applicable information returns) required by any law or regulation (whether
United States, foreign, state, local or other jurisdiction) filed by the
Company for each of the three fiscal years ended December 31, 1992, 1993 and
1994 and of all such returns filed separately by any Subsidiary for fiscal

Revenue Service (the "IRS") or by any other taxing authority.  Further, to the
knowledge of the Company, except to the extent specifically disclosed on
SCHEDULE 3.12, no state of facts exists or has existed that would subject the
Company or any Subsidiary to an additional material tax liability for any taxes
assessable by either the IRS or any separate state, local, foreign or other
taxing authority with respect to any reports or returns filed on or before the
date hereof (other than extension requests for which returns have not been
filed as of the date hereof).  Neither the Company nor any Subsidiary has, with
regard to any assets or property held, acquired or to be acquired by any of
them, filed a consent to the application of Section 341(f)(2) of the Code.

agreement or understanding to which the Company or any Subsidiary is a party or
may be bound and which would be required to be filed with the SEC in a filing
to which paragraph (b)(10) of Item 601 of Regulation S-K of the Rules and
Regulations of the SEC would be applicable.  The Company and each Subsidiary
has performed all obligations required to be performed by it under any listed
or material contract, plan, agreement, understanding or arrangement made or
obligation owed by or to the Company or any Subsidiary, except where the
failure would not have a Company Material Adverse Effect; there has not been
any event of default (or any event or condition which with notice or the lapse
of time, both or otherwise, would constitute an event of default) thereunder on
the part of the Company, any Subsidiary or, to the Company's knowledge, any
other party to any thereof that would have a Company Material Adverse Effect;
the same are in full force and effect and valid and enforceable by the Company
or its Subsidiaries in accordance with their respective terms subject to laws
of general application relating to bankruptcy, insolvency and the relief of
debtors and rules or law governing specific performance, injunctive relief and

<PAGE>   15

     3.14 Title to Properties; Liens.  The Company and/or its Subsidiaries have
good and marketable title to all properties and assets reflected on the Company
Audited Balance Sheet or acquired after the dates thereof (except for
properties and assets sold or otherwise disposed of in the ordinary course of
business since the dates thereof), which includes each asset the absence or
unavailability of which would have a Company Material Adverse Effect, subject
only to (a) statutory Liens arising or incurred in the ordinary course of
business with respect to which the underlying obligations are not delinquent,
(b) with respect to personal property, the rights of customers of the Company
or any Subsidiary with respect to inventory or work in progress under orders or
contracts entered into by the Company or any Subsidiary in the ordinary course
of business, (c) Liens reflected on the Company Audited Balance Sheet, (d)
Liens for taxes not yet delinquent and (e) and defects in title that would not
have a Company Material Adverse Effect.  The term "Lien" as used in this
Agreement means any mortgage, pledge, security interest, encumbrance, lien,
claim or charge of any kind.  All properties and assets purported to be leased
by the Company or any Subsidiary are subject to valid and effective leases that
are in full force and effect, and there does not exist, and the Merger will not
result in, any default or event that with notice or lapse of time, or both or
otherwise, would constitute a default under any such leases which would have a
Company Material Adverse Effect.  The properties and assets of the Company and
each Subsidiary have been kept in good condition and repair in the ordinary
course of business.

     3.15 Permits, Licenses, Etc..  The Company and each Subsidiary has all
rights, permits, certificates, licenses, consents, franchises, approvals,
registrations, and other authorizations necessary to sell its products and
services and otherwise carry on and conduct its business and to own, lease, use
and operate its properties and assets at the places and in the manner now
conducted and operated, except those the absence of which would not have a
Company Material Adverse Effect.  Neither the Company nor any Subsidiary has
received any notice or claim pertaining to the failure to obtain any permit,
certificate, license, franchise, approval, registration or other authorization
required by any federal, state, local or foreign body or authority (including,
but not limited to, the FDA or any nongovernmental self-regulatory agency).

     3.16 Intellectual Property Rights.  SCHEDULE 3.16 contains a complete and
accurate list of all patents, trademarks, trade names, service marks,
copyrights and applications for or registrations of any of the foregoing as to
which the Company or any Subsidiary is the owner or a licensee (indicating
whether such license is exclusive or nonexclusive).  The Company and each
Subsidiary exclusively owns, free and clear of any Lien (as defined in Section
3.14), or is exclusively (unless otherwise indicated in SCHEDULE 3.16) licensed
to use, all patents, trademarks, trade names, service marks, copyrights,
applications for or registrations of any of the foregoing, processes,
inventions, designs, technology, formulas, computer software programs, know-how
and trade secrets used in or necessary for the conduct of its respective
business as currently conducted or proposed to be conducted (the "Company
Intellectual Property").  Except to the extent specifically disclosed on
SCHEDULE 3.16, no claim has been asserted or, to the knowledge of the Company,
threatened by any person, and, to the Company's knowledge, no basis for any
claim exists, with respect to the use of the Company Intellectual Property or
challenging or questioning the validity or effectiveness of any license or
agreement with respect thereto.  To the knowledge of the Company, neither the
use of the Company Intellectual Property by the Company or any Subsidiary in
the present or planned conduct of its business nor any product or service of
the Company or any Subsidiary infringes on the intellectual property rights of
any person.  No current or former shareholder, employee or consultant of the
Company or any Subsidiary has any rights in or to any of the Company
Intellectual Property.  All the Company Intellectual Property listed on
SCHEDULE 3.16 has the status indicated therein and all applications are still
pending in good standing and have not been abandoned.  Except to the extent
specifically disclosed on SCHEDULE 3.16:  (i) the Company Intellectual Property
is valid and has not been challenged in any judicial or administrative
proceeding; (ii) the Company and each Subsidiary has made all statutorily
required filings, if any, to record its interests, and taken reasonable actions
to protect its rights, in the Company Intellectual Property; (iii) to the

business or products has infringed, misused or misappropriated the Company
Intellectual Property or currently is infringing, misusing or misappropriating
the Company Intellectual Property; and (iv) no other person or entity has any
right to receive or any obligation to pay a royalty with respect to any the
Company Intellectual Property or any product or service of the Company or any
Subsidiary.

           (c) Except to the extent specifically disclosed on SCHEDULE 3.17(C),
      neither the Company nor any Subsidiary sponsors, maintains, contributes
      to, or has sponsored, maintained, contributed to, or been required to
      contribute to, any "employee welfare benefit plan" ("Welfare Plan"), as
      such term is defined in Section 3(1) of ERISA, whether insured or
      otherwise, and any such Welfare Plan presently maintained by the Company
      or any Subsidiary is, in all material respects, in compliance with the
      provisions of ERISA, the Code and all other applicable laws, including,
      but not limited to, Sections 4980B of the Code and the regulations
      thereunder, and Part 6 of Title I of ERISA.  Except to the extent
      specifically disclosed on SCHEDULE 3.17(C), neither the Company nor any
      Subsidiary has established or contributed to any "voluntary employees'
      beneficiary association" within the meaning of Section 501(c)(9) of the

      "self-insured medical reimbursement plan" within the meaning of Section
      105(h) of the Code and the regulations thereunder.

           (e) Except to the extent specifically disclosed on SCHEDULE 3.17(E),

      benefit or welfare or other similar plan, policy, agreement, trust, fund
      or arrangement providing for the remuneration or benefit of all or any
      employees or shareholders or any other person, that is neither a Pension
      Plan nor a Welfare Plan (collectively, the "Compensation Plans").

           (f) To the knowledge of the Company, neither any Pension Plans or
      Welfare Plans nor any trust created or insurance contract issued
      thereunder nor any trustee, fiduciary, custodian, or administrator
      thereof, nor any officer, director or employee of the Company or any
      Subsidiary, custodian or any other "disqualified person" within the
      meaning of Section 4975(e)(2) of the Code, or "party in interest" within
      the meaning of Section 3(14) of ERISA, with respect to any such plan has
      engaged in any act or omission which could reasonably be expected to
      subject the Company or any Subsidiary, either directly or indirectly, to

      penalty imposed by Section 502 of ERISA.

           (g) Full and timely payment has been made of all amounts that the
      Company or any Subsidiary is required, under applicable law, with respect
      to any Pension Plan, Welfare Plan or Compensation Plan, or any agreement
      relating to any Pension Plan, Welfare Plan or Compensation Plan, to have
      paid as a contribution to each Pension Plan, Welfare Plan or Compensation
      Plan.  To the extent required by generally accepted accounting
      principles, the Company has made adequate provisions for reserves to meet
      contributions that have not been made because they are not yet due under
      the terms of any Pension Plan, Welfare Plan or Compensation Plan or
      related agreements.  There will be no change on or before the Closing
      Date in the operation of any Pension Plan, Welfare Plan or Compensation
      Plan or documents under which any such plan is maintained that will
      result in an increase in the benefit liabilities under such plan, except
      as may be required by law.  The IRS has issued favorable determination
      letters

      has provided to Parent complete and accurate copies of all Pension Plans,
      Welfare Plans, Compensation Plans and related agreements, annual reports
      (Form 5500), favorable determination letters, current summary plan
      descriptions, and all employee handbooks or manuals.

           (h) Except to the extent specifically disclosed on SCHEDULE 3.17(h),
      the execution of, and performance of the transactions contemplated in,
      this Agreement will not (either alone or upon the occurrence of any
      additional or subsequent events) constitute an event under any Pension
      Plan, Welfare Plan, Compensation Plan or other arrangement that will or
      may result in any payment (whether of severance pay or otherwise),
      acceleration, forgiveness of indebtedness, vesting, distribution,
      increase in benefits or obligation to fund benefits.  Except to the
      extent specifically disclosed on SCHEDULE 3.17(H), no amount that could
      be received (whether in cash or property or the vesting of property) as a
      result of any of the transactions contemplated by this Agreement by any
      employee, officer or director of the Company or any of its affiliates who
      is a "disqualified individual" (as such term is defined in proposed
      Treasury Regulation Section 1.280G-1) under any Pension Plan, Welfare
      Plan or Compensation Plan currently in effect would be an "excess
      parachute payment" (as such term is defined in Section 280G(b)(1) of the
      Code).

     3.18 Minute Books.  The minute books of the Company and the Subsidiaries,

shareholders, agents, properties, buildings, machinery, equipment, furniture,
fixtures or operations and a description of each claim made by the Company or
any Subsidiary during the three-year period preceding the date hereof under any

accurate copies of all documentation regarding claims made thereunder.  All
such policies of insurance are in full force and effect, have been issued for
the benefit of the Company or its Subsidiary by properly licensed insurance

incurred any uninsured or insured liability, for or based upon breach of
product warranty (other than warranty service and repair claims in the ordinary
course of business not material in amount or significance), strict liability in
tort, negligent manufacture of product, negligent provision of services or any
other allegation of liability, including or resulting in, but not limited to,
product recalls, arising from the materials, design, testing, manufacture,
packaging, labeling (including instructions for use) or sale of its products or
from the provision of services (hereafter collectively referred to as "Product

upon alleged Product Liability exists which would have a Company Material
Adverse Effect.

applicable Subsidiary therefor, conform to the specifications established
therefor and have been manufactured in accordance with applicable regulatory

Material Adverse Effect.  Except as specifically set forth on SCHEDULE 3.24,
the quantities of all inventories, materials and supplies of the Company and
each Subsidiary (net of the obsolescence reserve therefor shown on the Company
Audited Balance Sheet and determined in the ordinary course of business
consistent with past practice) are not obsolete, damaged, slow-moving,
defective or excessive, and are reasonable and balanced in the circumstances of
the Company and its Subsidiaries, except to the extent that the failure of such
inventories to be in such conditions would not have a Company Material Adverse
Effect.  SCHEDULE 3.24 sets forth a true and complete list of the addresses of
all warehouses or other facilities in which inventories of the Company or any
Subsidiary are located.

     3.25 Relations with Suppliers and Customers.  No material current supplier
of the Company or any Subsidiary has cancelled any contract or order for

either prior to or following the Merger.  Except as specifically set forth on
SCHEDULE 3.25, neither the Company nor any Subsidiary has, to the knowledge of

for the Company or have been retained by the Company as financial advisors

been provided to Parent prior to the date of this Agreement.

     3.27 Proxy Statement.  The Proxy Statement/Prospectus (as defined in
Section 5.4 hereof), and any amendments or supplements thereto, will comply in
all material respects with all applicable laws, and none of the information
relating to the Company or its affiliates included or incorporated therein or
in any amendments or supplements thereto, or any schedules required to be filed
with the SEC in connection therewith, will, at any time during the period
beginning at the time it is mailed to shareholders and ending at the time of

                      OF PARENT AND ACQUISITION SUBSIDIARY

corporation duly organized, validly existing and in good standing under the

power and authority to own, lease and operate its respective properties and to
carry on its business as now being conducted.  Each of Parent and Acquisition
Subsidiary is duly qualified and in good standing to do business in each
jurisdiction in which the property owned, leased or operated by it or the
nature of the business conducted by it makes such qualification necessary and
where the failure to qualify could have a Parent Material Adverse Effect (as
defined below).  The term "Parent Material Adverse Effect" means an effect
that, individually or in the aggregate with other effects, is or would
reasonably be expected to be materially adverse to the present or planned
business, properties, liabilities, results of operation or financial condition
of Parent and its subsidiaries, considered as a whole, or to Parent's ability
to perform any of its obligations under this Agreement or to consummate the
Merger.

     4.2 Authorization.  Each of Parent and Acquisition Subsidiary has full
corporate power and authority to execute and deliver this Agreement and to
consummate the transactions contemplated hereby, and Parent has full corporate

The execution and delivery of this Agreement by Parent and Acquisition
Subsidiary and the consummation of the transactions contemplated hereby have
been duly and validly authorized and approved by the Boards of Directors of
Parent and Acquisition Subsidiary and by Parent as the sole shareholder
of Acquisition Subsidiary, and no other corporate proceedings on the part of
Parent and Acquisition Subsidiary are necessary to authorize this Agreement or
the consummation of the transactions contemplated hereby.  This Agreement has
been duly and validly executed and delivered by each of Parent and Acquisition
Subsidiary and constitutes the valid and binding obligation of Parent and
Acquisition Subsidiary, enforceable against each of them in accordance with its
terms, subject to laws of general application relating to bankruptcy,
insolvency and the relief of debtors and rules of law governing specific
performance injunctive relief or other equitable remedies.

     4.3 Capitalization.  As of February 29, 1996, the authorized capital stock
of Parent consisted of (a) 800,000,000 shares of Common Stock with a par value
of $.10 per share, of which there were 234,131,829 shares issued and
outstanding and no shares held in Parent's treasury, and (b) 2,500,000 shares
of Preferred Stock with a par value of $1.00 per share, of which there were no

<PAGE>   20

of Acquisition Subsidiary consists of 2,500 shares of Acquisition
Subsidiary Common Stock, 100 of which are issued and outstanding and owned by
Parent.  All issued and outstanding shares of Parent Common Stock and
Acquisition Subsidiary Common Stock are, and the shares of Parent Common Stock
to be issued and delivered in the Merger pursuant to Article 1 hereof shall be,
at the time of issuance and delivery, validly issued, fully paid, nonassessable
and free of preemptive rights.  The shares of Parent Common Stock to be issued
and delivered in the Merger pursuant to Article 1 hereof shall be registered
under the 1933 Act and duly listed for trading on the NYSE, subject to official
notice of issuance.

     4.4 Consents and Approvals.  Except for (i) any applicable requirements of
the 1933 Act, the 1934 Act, state securities laws, the NYSE, the HSR Act, and
Foreign Merger Laws and (ii) the filing and recordation of appropriate merger
documents as required by the MBCA, the execution and delivery of this Agreement
by Parent and Acquisition Subsidiary and the consummation of the transactions
contemplated hereby will not: (a) violate any provision of the Articles or
Certificate of Incorporation or Bylaws of Parent or Acquisition Subsidiary; (b)
violate any statute, rule, regulation, order or decree of any public body or
authority (including, but not limited to, the FDA or any nongovernmental
self-regulatory agency) by which Parent or any of its subsidiaries or any of
their respective properties or assets may be bound; (c) require any filing with
or permit, consent or approval of any public body or authority (including, but
not limited to, the FDA or any nongovernmental self-regulatory agency); or (d)
result in any violation or breach of, or constitute (with or without due notice
or lapse of time or both) a default under, result in the loss of any material
benefit under, or give rise to any right of termination, cancellation,
increased payments or acceleration under, or result in the creation of any Lien
on any of the properties or assets of Parent or its subsidiaries under, any of
the terms, conditions or provisions of any note, bond, mortgage, indenture,
license, franchise, permit, agreement or other instrument or obligation to
which Parent or any of its subsidiaries is a party, or by which any of them or
any of their respective properties or assets may be bound, except, in the case
of clause (d), for any such violations, breaches, defaults or other occurrences
which would not prevent or delay consummation of any of the transaction
contemplated hereby in any material respect, or otherwise prevent Parent from
performing its obligations under this Agreement in any material respect, and
would not have a Parent Material Adverse Effect.

     4.5 Reports; Financial Statements; Absence of Changes.  Parent has filed
all forms, reports, registration statements and documents required to be filed
by it with the Securities and Exchange Commission ("SEC") since December 31,
1994 (such forms, reports, registration statements and documents, together with
any amendments thereto, are referred to as the "Parent SEC Filings").  As of
their respective dates, the Parent SEC Filings (i) complied as to form in all
material respects with the applicable requirements of the 1933 Act and the 1934
Act, as the case may be, and (ii) did not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements made therein, in light of the circumstances
under which they were made, not misleading.  The audited financial statements
and unaudited interim financial statements included or incorporated by
reference in the Parent SEC Filings (i) were prepared in accordance with
generally accepted accounting principles applied on a consistent basis during
the periods involved (except as may be indicated therein or in the notes
thereto), (ii) complied as of their respective dates in all material respects
with applicable accounting requirements and the published rules and regulations
of the SEC with respect thereto, and (iii) fairly present the consolidated
financial position of Parent as of the dates thereof and the income, cash flows
and changes in shareholder's equity for the periods it involved.  Except to the
extent disclosed in Parent's subsequent filings with the SEC or specifically
disclosed on SCHEDULE 4.5, since April 30, 1995 there has not been any change
or circumstance that would have a Parent Material Adverse Effect.

     4.6 Registration Statement.  The Registration Statement (as defined in
Section 5.4 hereof) and any amendments or supplements thereto will comply in
all material respects with the 1933 Act, and none of the information relating
to Parent or its affiliates included or incorporated therein or in any
amendments or supplements thereto, or any schedules required to be filed with
the SEC in connection therewith will, at the time the Registration Statement
becomes effective or at the Effective Time, 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 were made, not misleading; provided, however,
that no representation or warranty is made by Parent with respect to
information supplied by the Company or any affiliate of the Company
specifically for inclusion in the Registration Statement.

in all material respects with the applicable requirements of the HSR Act, the
rules and regulations issued by the Federal Trade Commission pursuant thereto

      proxy and any letter or other materials to the Company shareholders
      included therein are referred to in this Agreement as the "Proxy
      Statement/Prospectus").  The Company shall use all reasonable efforts to

      shareholders of the Company, as soon as reasonably practicable following
      its effectiveness, with the date of mailing as mutually determined by the
      Company and Parent.  The Company will, through its Board of Directors,
      recommend to its shareholders approval of the Merger in the definitive
      Proxy Statement/Prospectus.

           (b) Parent shall, with the cooperation of the Company, prepare and
      file, as soon as reasonably practicable, a registration statement under
      the 1933 Act registering the shares of Parent Common Stock to be issued

      also take any action required to be taken under state blue sky or
      securities laws in connection with the issuance of Parent Common Stock

      information concerning the Company and its Subsidiaries and the holders

      Registration Statement.

      Registration Statement, the Company or Parent, as the case may be, shall,
      upon learning of such event, promptly notify the other and consult and
      cooperate with the other in connection with the preparation of a mutually

reasonable efforts to take, or cause to be taken, all action, and to do, or
cause to be done, all things necessary, proper or advisable to consummate and
make effective the transactions contemplated by this Agreement.  In case at any

each party to this Agreement shall take all such necessary action.

     5.9 Regulatory Approvals.  The Company and Parent will take all reasonable
action as may be necessary under federal or state securities laws or the HSR
Act or Foreign Merger Laws applicable to or necessary for, and will file as

party shall give the other information reasonably requested by such other party
pertaining to it and its subsidiaries and affiliates to enable such other party

contrary, neither Parent nor Acquisition Subsidiary shall be required to make
arrangements for or to effect the 

                                    A-25
<PAGE>   26

cessation, sale or other disposition of particular assets or categories
of assets or businesses of Parent, Acquisition Subsidiary, the Company or any
of their affiliates.

     5.10 Certain Notifications.  The Company shall promptly notify Parent in
writing of the occurrence of any event that will or could reasonably be
expected to result in the failure by the Company or its affiliates to satisfy

reasonably be expected to result in the failure by Parent or its affiliates to

each person who is now, or has been at any time prior to the date hereof or who
becomes prior to the Effective Time, an officer, director or employee of the
Company or any of its Subsidiaries (the "Indemnified Parties") against all
losses, claims, damages, costs, expenses (including reasonable attorneys' fees
and expenses), liabilities or judgments, or amounts that are paid in settlement
with the approval of Parent (which approval shall not be unreasonably
withheld), of or in connection with any claim, action, suit, proceeding or
investigation based in whole or in part on or arising in whole or in part out
of the fact that such person is or was a director, officer or employee of the
Company or any Subsidiary, whether pertaining to any matter existing or
occurring at or prior to the Effective Time and whether asserted or claimed
prior to, or at or after, the Effective Time, including, without limitation,
this Agreement and the transactions contemplated hereby ("Indemnified
Liabilities"), in each case to the full extent the Company would have been
permitted under Delaware law and its Certificate of Incorporation and Bylaws as
of the Effective Time to indemnify such person (and Parent shall pay expenses
in advance of the final disposition of any such action or proceeding to each
Indemnified Party to the full extent permitted by law upon receipt of any
affirmation or undertaking required by Section 145(e) of the DGCL).  Without
limiting the foregoing, in the event any such claim, action, suit, proceeding
or investigation is brought against any Indemnified Party (whether arising
before or after the Effective Time), (i) any counsel retained by the
Indemnified Parties for any period after the Effective Time shall be reasonably
satisfactory to Parent; (ii) after the Effective Time, Parent shall pay all
reasonable fees and expenses of such counsel for the Indemnified Parties
promptly as statements therefor are received; and (iii) after the Effective
Time, Parent will use all reasonable efforts to assist in the vigorous defense
of any such matter, provided that Parent shall not be liable for any settlement
of any claim effected without its written consent, which consent, however,
shall not be unreasonably withheld.  Any Indemnified Party wishing to claim
indemnification under this Section 5.14, upon learning of any such claim,
action, suit, proceeding or investigation, shall notify Parent (but the failure
so to notify Parent shall not relieve it from any liability which it may have
under this Section 5.14 except to the extent such failure materially prejudices
Parent), and shall deliver to Parent the affirmation and undertaking, if any,
required by Section 145(e) of the DGCL.  The Indemnified Parties as a group may
retain only one law firm to represent them with respect to each such matter
unless there is, under applicable standards of professional conduct, a conflict
of any significant issue between the positions of any two or more Indemnified
Parties.  In the event of any dispute as to the enforcement or interpretation
of an Indemnified Party's rights under this Section 5.14 and the Indemnified
Parties are held by a court of competent jurisdiction to have been entitled to
indemnification under this Section 5.14, Parent shall promptly reimburse the
Indemnified Party's fees and expenses (including reasonable attorneys' fees and
expenses) incurred in connection with such matter.  The obligations of Parent
to an Indemnified Party under this Section 5.14 shall survive and continue
after the Effective Time, and shall inure to the benefit of 

                                    A-26
<PAGE>   27

the Indemnified Party for all Indemnified Party's heirs, legal
representatives, administrators and other successors in interest.  It is
expressly understood and agreed that (i) each Indemnified Party shall be
considered a third party beneficiary of this Section 5.14 and (ii) the parties
hereto will not amend or modify the provisions of this Section 5.14 so as to
adversely affect the rights of an Indemnified Party without in each instance
first obtaining the prior written consent to such amendment or modification of
all Indemnified Parties.

     5.15 Letters of the Company's and Parent's Accountants.  (A) The Company
shall cooperate with Parent and use all reasonable efforts to cause to be
delivered to Parent the following letters from Price Waterhouse LLP
("PW") addressed to the Company and Parent:  (i) a letter dated the date of
this Agreement, stating that after appropriate review and based on its
familiarity with the Company, the Company has not taken or agreed to take any
action that would prevent Parent from accounting for the Merger as a pooling of
interests transaction under Option 16 of the Accounting Principles Board and
applicable SEC rules and regulations; and (ii) a letter dated as of the Closing
Date confirming as of the Closing Date the previously delivered letter referred
to above.  (B) The Company shall cooperate with Parent and Parent shall use all
reasonable means to cause to be delivered to the Company the following letters
from PW addressed to Parent and the Company:  (i) a letter dated the date of
this Agreement, stating that after appropriate review of this Agreement and a
letter from the Parent describing the transaction, the Merger will qualify as a
pooling of interests transaction under Opinion 16 of the Accounting Principles
Board and applicable SEC rules and regulations; and (ii) a letter dated as of
the Closing Date confirming as of the Closing Date the previously delivered
letter referred to above.  The fees charged by PW for such letters shall be
shared equally by Parent and the Company

revise, to such terms as are mutually satisfactory to the Company and Parent,
the Company's royalty payment obligations to the parties to that certain
Assignment Agreement dated April 25, 1991, as amended, among the Company and
others.

     5.17 Pooling; Reorganization.  From the date hereof to the Effective Time,
Parent agrees that it will not knowingly take any action that would have the
effect of (i) jeopardizing the treatment of the acquisition of the Company by
Parent as a "pooling of interests" for accounting purposes, or (ii)
jeopardizing the qualification of the Merger as a reorganization within the
meaning of Section 368(a)(2)(E) of the Code.

     5.18 Subsidiary Shares.  At or prior to the Closing, the Company shall
cause all issued and outstanding Subsidiary shares owned by any person other
than the Company to be transferred for no or nominal consideration to such
person or persons designated by Parent.

           (b) by either Parent or the Company if the Merger shall not have

      obtained, except that the right to terminate this Agreement under this
      Section 7.1(e) will not be available to any party whose failure to
      perform any material obligation under this Agreement has been the
      proximate cause of, or resulted in, the failure to obtain the requisite
      vote of the shareholders of the Company;

           (e) by Parent if either (i) the Company has breached its obligations
      under Section 5.2 in any material respect, (ii) the Board of Directors of

      obligations under this Agreement such that the conditions in Section 6.2
      will not be satisfied, and the breach is not curable or, if curable, is
      not cured by the Company within 30 calendar days after receipt by the
      Company of written notice from Parent of such breach;

           (h) by the Company if (i) the Company is not in material breach of
      its obligations under this Agreement and (ii) there has been a material
      breach by Parent of any of its representations, warranties or obligations
      under this Agreement such that the conditions in Section 6.3 will not be
      satisfied, and the breach is not curable or, if curable, is not cured by
      Parent within 30 calendar days after receipt by Parent of written notice
      from the Company of such breach.

     7.2 Effect of Termination.

           (a) In recognition of the time, efforts and expenses expended and
      incurred by Parent with respect to the Company and the opportunity the
      Company presents to Parent, if:

                 (i) this Agreement is terminated pursuant to Section 7.1(e) or
            7.1(f); or

                 (ii) (A) any third party makes an Alternative Proposal or

            shareholders of the Company to approve the Merger is not obtained,
            (C) this Agreement is terminated, and (D) within 12 months after
            such termination (x) the Company enters into an agreement relating
            to an Alternative Proposal or (y) an Alternative Proposal is
            consummated,

      then, in any such event, the Company will pay to Parent, upon the
      termination date in the event of termination pursuant to Section 7.1(f),
      within five business days after demand by Parent in the case of
      termination pursuant to Section 7.1(e), and immediately upon the first to
      occur of the entering into an agreement providing for, or the
      consummation of, an Alternative Proposal in the case of the events
      specified in clause (ii) above (by wire transfer of immediately available
      funds to an account designated by Parent for such purpose), a fee equal
      to $5 million.  The Company acknowledges that the agreements contained in
      this Section 7.2 are an integral part of the transactions contemplated by
      this Agreement, and that, without these agreements, Parent would not
      enter into this Agreement.  If the Company fails to pay 

                                    A-30
<PAGE>   31

      promptly the fee due pursuant to this Section 7.2, the Company shall
      also pay to Parent interest on the amount of the fee under this Section,
      accruing from its due date, at an interest rate per annum equal to 2%
      plus the prime commercial lending rate quoted by Norwest Bank Minnesota,
      N.A.  Any change in the interest rate hereunder resulting from a change
      in such prime rate shall be effective at the beginning of the day of such
      change in such prime rate.

      the event of the termination of this Agreement pursuant to any paragraph
      of Section 7.1, the obligations of the parties to consummate the Merger
      will expire, and none of the parties will have any further obligations
      under this Agreement except pursuant to  Section 7.2(a), Sections 5.3 and
      5.7 and Article 8.  In the event of the termination of this Agreement
      pursuant to any paragraph of Section 7.1 that is caused by a breach of a
      party, the party whose breach was the basis for the termination will not
      be relieved from any liability for its breach or its obligations pursuant
      to Section 7.2(a), and the other party will have no further obligations
      under this Agreement except as provided in Sections 5.3 and 5.7 and
      Article 8.

distributors, agents or dealers have previously been appointed in the Territory
for the Products.  In the event that as of the Effective Date of this Agreement
there are presently appointed any other distributors for the Products in the
Territory, InStent shall use all reasonable efforts to terminate all such other
distributors at the earliest possible date following the Effective Date.

     1.3 Independent Contractor.  Distributor is an independent contractor and
is not and shall not act as the agent, employee, franchisee or partner of
InStent.

obligation, express or implied, on behalf of the other party hereto.

     1.5 Sub-contract or Resale.  During the Term hereof, Distributor may sell
the Products to customers who intend to resell the Products.  Distributor may
sub-contract distributorship of the Products to any third party, entity, firm
or agent.

     1.6 Acceptance.  Distributor accepts its appointment as Distributor of the
Products in the Territory and shall use its reasonable efforts to develop sales
of the Products, in the Territory, and to support InStent's marketing program
in the Territory.  In furtherance thereof, Distributor shall:

     (a) keep on hand a reasonable inventory of the Products sufficient to
allow for prompt delivery of Products to purchasers;


<PAGE>   2

                                       2




     (b) participate regularly in local or regional trade shows, medical
conventions or like events within the Territory, and conduct regular local
promotional, advertising and other marketing efforts for the Products;

     (c) provide appropriate and professional application advice and counseling
for the Products sold by Distributor, and provide prompt follow-up service and
advice to purchasers of the Products when so requested by the purchaser or by
InStent;

     (e) maintain and make available to InStent periodically, as reasonably
requested by InStent, accurate records of Distributor's sales of Products under

Distributor for its documented, reasonable, out-of-pocket expenses in
connection with repurchasing Products subject to recall;

     (g) promptly advise InStent of each complaint that Distributor receives or
becomes aware of concerning the Products, and promptly notify InStent as
required by applicable law to report any information of which Distributor

in any way with an injury to a user or patient;

     (h) advise InStent of any inquiry other than a purchase order or potential

U.S. Dollars unless provided otherwise on the applicable invoice.

     3.2 Taxes.  Distributor's prices for the Products and other amounts

Distributor shall make payment to InStent for Products purchased hereunder in

shipments in transmit if (i) all prior invoices are not paid in full, or (ii)
InStent reasonably deems such steps necessary to secure payment.

     3.5 Interest.  Any amount not paid when due will be subject to finance
charges at the rate of one and one-half percent (1.5%) per month or the maximum
rate permitted by applicable law, whichever is less, determined and compounded
on a daily basis from the date due until the date paid.  Payment of such
finance charges will not excuse or cure Distributor's breach or default for
late payment.  If InStent retains a collection agency, attorney or other person
or entity to collect overdue payments, all collection costs, including but not
limited to reasonable attorney's fees, will be payable by Distributor.

                             DISTRIBUTION AGREEMENT

     This Agreement, dated January 9, 1996, is made between InStent Inc., a
Delaware corporation ("InStent"), and C.R. Bard, Inc. a New Jersey corporation
acting through its Bard Interventional Products Division ("Distributor").

     InStent and Distributor, in consideration of the agreements and covenants
contained herein, and for other good and valuable consideration, the receipt of
which is hereby acknowledged, agree as follows:

Section I - Appointment

     1.1 Distributor.  InStent hereby appoints Distributor for the Term (as
defined in Paragraph 7.1) and subject to the terms and conditions of this
Agreement, as its distributor of the Products, and only the Products, of
InStent identified on the attached Exhibit A (the "Products") within the
territory described on the attached Exhibit B (the "Territory").

     1.2 Exclusivity.  InStent shall not (i) appoint another distributor of the
Products whose territory includes any portion of the Territory during the Term,
(ii) market Products within the Territory during the Term, or (iii) effect
direct sales of the Products to dealers or retailers located within the
Territory during the Term.  Notwithstanding the foregoing, InStent's
distributors as of the date first above written will continue to have the right
to sell the Products in the Territory through January 31, 1996.  InStent
represents and warrants to Distributor that InStent has the right to and will
terminate by February 1, 1996, its agreements with all such InStent
distributors.  InStent agrees to indemnify, defend and hold harmless
Distributor from and against any suit by any such InStent distributor arising
out of, pertaining to or resulting from InStent's termination of its existing
agreement with such distributor.

     1.3 Independent Contractor.  Distributor is an independent contractor and
is not and shall not act as the agent, employee, franchisee or partner of
InStent.

     1.4 No Creation of Obligation by One Party for Other.  Neither party
hereto shall be entitled to, nor shall attempt to, create or assume any
obligation, express or implied, on behalf of the other party hereto.

     1.5 Sub-contract or Resale.  During the Term hereof, Distributor may sell
the Product to customers who intend to resell the Product, if, and only if,
such customers agree not to resell the Product outside the Territory.
Distributor may sub-contract distributorship of the Product to any third party,
entity, firm or agent.  If any purchaser of the Product from Distributor
resells or distributes the Product outside the Territory, Distributor shall
cease selling the Product to such purchaser upon learning of such sales
outside the Territory, and shall (or permit InStent to) enforce the prohibition
against such resale outside the Territory.

     1.6 Acceptance.  Distributor accepts its appointment as Distributor of the

the Territory.  In furtherance thereof, Distributor shall:

           (a) Keep on hand a reasonable inventory of the Products (defined as

      for prompt delivery of Products to purchasers;

           (b) Participate regularly in local or regional trade shows, medical
      conventions or like events within the Territory, and conduct regular
      local promotional, advertising and other marketing efforts for the

           (c) Provide appropriate and professional application advice and
      counseling for each unit of the Products sold by Distributor, and provide

      requested by the purchaser or by InStent;

           (d) Respond promptly to sales leads or referrals furnished by

           (f) Assist promptly in executing Product recalls as directed by

      reasonable, out-of-pocket expenses in connection with repurchasing
      Products subject to recall;

           (g) Promptly advise InStent of each complaint that Distributor may
      receive or become aware of concerning the Products, and notify InStent

      may have been associated in any way with an injury to a user or patient;

           (h) Refer to InStent any inquiry other than a purchase order or

      materials developed by Distributor (the "Distributor Materials") without
      the prior written approval of InStent (such approval not to be

      proceedings and any damages, liability, losses, costs and expenses
      (including, but not limited to, attorneys' fees) arising out of or related
      to any such Distributor Materials, which were not prior to their use
      approved in writing by InStent.

           (k) Bard agrees to furnish InStent all sales records for the first
      six months so that InStent can compensate its previous reps.

      Products may have been associated in any way with an injury to a user or
      a patient.

           (e) InStent will provide Distributor reasonable advance notice with
      respect to proposed modifications to the Products or the specifications;

      current FDA approvals or InStent will obtain the needed FDA approvals to
      market.

           (f) At the expense of Distributor, InStent will assess the
      feasibility of modifications to the Products or the specifications
      proposed by Distributor and will notify Distributor with respect to cost
      changes which are subject to Distributor's approval, such approval not to
      be unreasonably withheld.


Section 2 - Forecasts

     2.1 Forecasts.  Upon execution of this Agreement and at least thirty (30)
days before the beginning of each three-month period thereafter, Distributor
shall fumish InStent with a rolling forecast of sales for the following twelve
(12) months of Products by units, and an estimate of Distributor's forthcoming
orders for Products during the next three months.  Upon execution of this
Agreement and sixty (60) days prior to the beginning of each three-month period
thereafter, Distributor will submit a purchase order for at least eighty
percent (80%) of the 

                                      3

<PAGE>   4

Products estimated to be purchased pursuant to Distributor's estimate for such
three-month period.


Section 3 - Terms of Sale.

      3.1  Price.

           (a) Price to Distributor of the Products for the first twelve months
      of this Agreement shall be $700 for each EndoCoil biliary stent and $850
      for each EsophaCoil esophageal stent.  Within ninety (90 days) of last
      day of such twelve-month period, the parties shall review the
      Distributor's average sales price of each stent during such twelve month
      period (the "Base Average Sales Price") and adjust the price at which
      each stent is sold by InStent to Distributor so as to Yield to
      Distributor a gross profit margin of 50% on the Base Average Sales Price,
      provided that if such adjustment would result in a reduction of InStent's
      gross profit margin below fifty percent (50%), then Distributor's gross
      profit margin otherwise required hereby shall be reduced by such amount
      as shall yield to InStent a gross profit margin of 50%.  Such adjusted
      sales prices shall be retroactive to the first day of the second twelve
      month period of this Agreement and shall be hereinafter referred to as
      the "Base Price(s)." Within ninety (90) days of last day of the second
      twelve month period of this agreement, the parties shall review the
      average sales price of each stent during such twelve month period.  The
      Base Price of each stent shall be then adjusted retroactive to the first
      day of the third twelve month period of this Agreement to reflect the
      following with regard to each stent: (i) any decrease during the second
      twelve month period of this Agreement in Distributor's average sales
      price below the Base Average Sales Price will be shared equally by
      InStent and Distributor (for example, if Distributor's average sales
      price declines by 10% below the Base Average Sales Price, InStent will
      reduce its Base Price to Distributor by 5%), (ii) if during the second
      twelve month period of this Agreement Distributor's average sales price
      increased above the Base Average Sales Price, InStent can proportionally
      increase its Base Price to Distributor up to a maximum of $500 per stent,
      (iii) InStent is not required to pass through to Distributor any decrease
      in the manufacturing cost of a Product, and (iv) if any adjustment
      pursuant to the preceding clauses (i), (ii) or (iii) would result in a
      reduction of InStent's gross profit margin below fifty percent (50%) then
      Distributor's gross profit margin otherwise required hereby shall be
      reduced by such amount as shall yield to InStent a gross profit margin of
      50%.


           (b) Notwithstanding anything set forth herein, all prices are 
      payable in U.S. Dollars unless provided otherwise on the applicable 
      invoice.

     3.2 Taxes.  The purchase prices and other amounts specified in this
Agreement do include sales, use or other applicable taxes, unless expressly
stated to the contrary.  Distributor will pay all such taxes.

     3.3 Delivery.  InStent will deliver all Products sold to Distributor FOB
Eden Prairie, Minnesota, U.S.A. Title to, and all risk or loss of or damage or
casualty to, such Products will pass to Distributor upon delivery.  As invoiced
to Distributor by InStent, Distributor will reimburse InStent for all shipping
charges, premiums for freight insurance, customs duties and other import and
export fees, and other transportation costs incurred by InStent.  Distributor
shall have the right to reject the Products for failure to meet its Quality
Assurance/Regulatory Assurance standards by returning such Products to InStent
within fifteen (15) days of delivery for credit of the purchase price or
replacement of the Product.  Prior to returning any such Products, Distributor
shall first obtain a Return Goods Authorization number from InStent which shall
be included with the return shipment.

     3.4 Payment.  Unless specified otherwise in the applicable order, payment
shall be made in full within thirty (30) days of the date of InStent's invoice.
InStent may, at its discretion, refuse orders, require payment in full, ship
C.O.D. or halt shipments in transmit if (i) all prior invoices are not paid in
full, or (ii) InStent reasonably deems such steps necessary to secure payment.

     3.5 Interest.  Any amount not paid when due will be subject to finance
charges at the rate of one and one-half percent (1.5%) per month or the maximum
rate permitted by applicable law, whichever is less, determined and compounded
on a daily basis from the date due until the date paid.  Payment of such
finance charges will not excuse or cure Distributor's breach or default for
late payment.  If InStent retains a collection agency, attorney or other person
or entity to collect overdue payments, all collection costs, including but not
limited to reasonable attorney's fees, will be payable by Distributor.

     3.6 Returns.  Distributor shall not return Products to InStent without
InStent's prior authorization promptly confirmed in writing except as otherwise
provided in paragraph 3.3.

infringement.  InStent will have exclusive control over the prosecution and
settlement of any such legal proceeding, and Distributor will provide such

      InStent in connection with such compliance will be borne solely by

writing by InStent.  Distributor shall not advise, perform or demonstrate any
use or application of any Products that are not specifically approved in
writing by InStent.  Distributor shall defend, indemnify and hold harmless
InStent from any claims, actions and proceedings and any damages, liability,
losses, costs and expenses (including, but not limited to, attorneys' fees)
arising out of or related to any breach of this paragraph by Distributor.

      6.2  Compliance With Laws.

           (a) General.  Distributor represents to InStent that Distributor is
      thoroughly familiar with applicable regulations concerning the use,
      handling, sale and disposition of the Products in the Territory.
      Distributor shall comply with all laws, ordinances and regulations of any
      governmental entity having jurisdiction applicable to its business with
      respect to the importation, sale, demonstration, use and disposition of
      Products, and shall defend, indemnify and hold InStent harmless from all 
      claims, losses, damages, costs and liabilities (including, but not 
      limited to attorneys' fees) arising out of any failure of Distributor to
      comply with this Section 6.  Distributor shall not impair the sterility 
      or integrity of the Products while they are in Distributor's custody.

           (b) Export Control.  Without limiting the generality of paragraph
      6.2(a), Distributor will not, directly or indirectly, export or re-export
      any Products, technical data associated with the Products, or the
      immediate products (including, but not limited to, processes, services,
      data and reports) derived from use of the Products from the Territory,
      without first obtaining the appropriate license from the U.S. Office of
      Export Licensing or its successor.

     6.3 Financial Assurance.  Distributor shall maintain in force for the Term
liability insurance in such form and written by such insurers as may be
reasonably satisfactory to InStent, in a minimum coverage of $1,000,000
combined single limit, covering Distributor's activities in furtherance of this
Agreement including the operation of Distributor's motor vehicles.  Distributor
shall provide InStent not less than thirty (30) days advance notice of
cancellation or material change in any such policies.


Section 7 - Term and Termination

     7.1 Term.  This Agreement shall be in effect for a term of three (3) years
from the date of this Agreement, unless sooner terminated under paragraph 7.2.
Upon expiration of the Term, this Agreement shall terminate without further act
or deed of either party.  If InStent is acquired or merges with another company
during the Term, the acquiring company or the surviving company, as the case
may be, shall have the option to terminate this Agreement upon one (1) year
prior written notice to Distributor provided the terminating party agrees, upon
Distributor's request, to repurchase from Distributor at their original
invoiced price all or any portion of those Products in the Distributor's
inventory as of the termination date that are in unopened, factory packaging
and whose expiration date has not expired.

     7.2 Termination.  Upon any breach of or default under this Agreement by
either party, the other party may notify the party alleged to be in breach of
such fact in writing specifying the breach, whereupon the party alleged to be
in breach has thirty (30) days to cure the breach.  Failure to cure such breach
within the thirty (30) day period, or any chronic breach of this Agreement
whether cured or not, shall entitle the party giving notice to terminate this
Agreement, effective immediately, by giving written notice to the other party.
In addition, InStent may terminate this Agreement immediately by notice to
Distributor and reject, or revoke acceptance of, any orders for Products not
then in the hands of Distributor if Distributor engages in any act, practice or
omission that threatens the health or safety of users of the Products or their
patients, or that impairs or imminently threatens to impair the goodwill
associated with the Trademarks.

     7.3  Cause.

           (a) Notwithstanding the foregoing, InStent reserves the right to
      earlier terminate Distributor's appointment ("termination for cause")
      such termination to be 


                                      10

<PAGE>   11
      effective thirty (30) days after the date of the written notice to that 
      effect from InStent, in the event that any of the following events shall
      occur:

                  (1) If Distributor fails during any calendar quarter to
             maintain the required inventory of Products;

                  (2) If three or more consecutive months elapse in which
             Distributor's monthly account receivable statement discloses
             monies due from Distributor to InStent beyond thirty (30) days
             from the date of invoice, or if Distributor is late in payment of
             InStent Product invoices in six (6) or more of any twelve (12)
             consecutive months during any Term.

                  (3) If Distributor sells or takes orders for the Products in
             violation of its Territory;

                  (4) If Distributor carries or offers any Products in
             competition with those offered by InStent except as permitted
             pursuant to Section 8 hereof,

                  (5) Upon the appointment of a receiver for the property,
             rights, credits or assets of Distributor, or any part of these
             categories;

                  (6) Upon Distributor's admission that it is unable to pay its
             debts as they become due, and/or the filing of a petition by or
             against Distributor under any law, the purpose of which is for the
             relief of debtors, bankruptcy, or any similar such reorganization;
             or

                  (7) Upon an assignment by Distributor of any assets for the
             benefit of creditors.

     7.4 Right of Negotiation.  Beginning six (6) months prior to the end of
the Term, InStent and Distributor will begin to negotiate in good faith for an
extension of the Term; provided, that the Agreement has not been otherwise
terminated pursuant to Paragraph 7.2 or 7.3. If InStent and Distributor have not
entered into a written extension of the Term of the Agreement prior to the end
of the Term, neither party shall have any further obligations under this
Paragraph 7.4.

     7.5 Winding up.  In the event of termination, InStent will credit
Distributor's account with any orders from Distributor which are shipped by
InStent prior to the date of termination.  Distributor agrees to cooperate with 
InStent in an orderly winding up of its affairs with InStent and extend all 
reasonable assistance to any successor for its Territory.  Upon notice of 
termination all orders for Products not within the inventory of Distributor 
from Distributor will be shipped to Distributor's customer therefore by InStent 
and InStent will bill the customer directly, paying Distributor a fee of 10% of 
the invoice price (net of tax, freight, commissions, 


                                      11


<PAGE>   12
insurance of other non-Product related charges) therefore, such fee to be paid
upon receipt by InStent of the customer's payment of the invoice.

     7.6 Consequences.  Upon any termination or expiration of any Term, all
sums due to InStent shall become immediately due and payable.  Distributor may,
but shall not be obligated to, upon the termination or expiration of the Term,
sell any Products in Distributor's inventory as to which Distributor had
distribution rights hereunder during the Term.  Except as otherwise provided in
paragraph 7.1, InStent may, but shall not be obligated to, repurchase at their
original invoiced price all or any portion of the Products in Distributor's
inventory, which six (6) months after the end of the Term have not been sold by
Distributor, that are still in their factory packaging and unopened.  InStent
shall pay the purchase price for such Products upon Distributor's tender of the
Products with a bill of sale conveying marketable title to the Products free
and clear of all other claims and interests.  Delivery shall be F.O.B.
Distributor's principal place of business.  Subparagraphs 1.6(g) and (h),
Paragraphs 4.1, 4.2, 4.5, 5.3, 5.4 and 6.1 and Section 8 (and any other
provisions which can reasonably be interpreted as surviving the expiration or
termination of the Term) shall survive the expiration or termination of the
Term.


Section 8 - Competition.

     Requirement Not to Compete.  Distributor will not, for itself or on behalf
of any person, firm, entity or corporation other than InStent, directly or
indirectly, offer for sale or solicit, within the Territory, orders for any
expandable stents competitive with the Products:

              (a)  during the Term; and

              (b)  if this Agreement is terminated by InStent (x) for cause
                   pursuant to Paragraph 7.3, or (y) on account of breach or 
                   default by Distributor pursuant to Paragraph 7.2; then 
                   for a period thereafter ending the earlier of (i) six 
                   months after the termination of this Agreement or (ii)
                   the date upon which InStent has entered into an agreement
                   for, or otherwise established, distribution of the Products
                   in the Territory.

For the purposes of this Section 8, Distributor shall include any person or
entity controlled by, controlling or under common control with Distributor.

Section 9 - Miscellaneous

     9.1 Limitation of Liability EXCEPT FOR CLAIMS ARISING UNDER PARAGRAPH 1.2
OR PARAGRAPH 5.4, INSTENT'S LIABILITY (WHETHER IN TORT, CONTRACT OR OTHERWISE

common control with Distributor.  No assignment by Distributor, with or without

signed by the party to be charged thereby.

     9.8 Nonwaiver.  The failure of either party to insist upon or enforce
strict performance of any of the provisions of this Agreement or to exercise
any rights or remedies under this Agreement will not be construed as a waiver
or relinquishment to any extent of such party's right

                              SECOND AMENDMENT TO
                              ASSIGNMENT AGREEMENT


     This Second Amendment to Assignment Agreement is dated as of
March 22, 1996, by and between Daniel Yachia, a resident of Natania,
Israel ("Yachia"), Seila Yachia, a resident of Turkey ("Assignee"), Mordechay
Beyar, a resident of Tel-Aviv, Israel ("Beyar"), Rafael Beyar, a resident of
Haifa, Israel ("Rafael"), Modern Therapeutic Modalities Ltd., a corporation
organized and formed under the laws of Israel ("MTML"), Meir Bachar, a resident
of Tel Aviv, Israel ("Distributee"), Lewis C. Pell, a resident of Armonk, New
York, U.S.A. ("Pell"), Katsumi Oneda, a resident of Alpine, New Jersey, U.S.A.
("Oneda"), Warren L. Bielke, a resident of Minneapolis, Minnesota, U.S.A.
("Bielke") and InStent Inc. (formerly known as StenTek Inc.), a corporation
duly organized and formed under the laws of the State of Delaware, U.S.A.
("InStent").

                                   RECITALS:

     A. On April 25, 1991, certain of the parties hereto entered into an
Assignment Agreement which was amended by an Addendum dated as of May 31, 1991,
a Second Addendum dated as of April 30, 1992 and an Amendment Agreement dated
as of June 27, 1995 (said Agreements, together with the first and second
Addendums and Amendment Agreement shall hereinafter be referred to as
"Assignment Agreement").

     B. Medtronic, Inc., a Delaware, U.S.A. corporation ("Medtronic") and
InStent propose to enter into an Agreement and Plan of Reorganization of even
date herewith (the "Merger Agreement"), pursuant to which, on the Effective
Date, as defined in the Merger Agreement, Medtronic will acquire the capital
stock and business (including good-will) of InStent by the merger of a wholly
owned subsidiary of Medtronic with and into InStent (the "Merger").

     C. The parties hereto desire to induce Medtronic to enter into the Merger
Agreement and consummate the transactions contemplated thereby.

     D. The royalty set forth in Section 3 of the Assignment Agreement was
payable to MTML or its designees.

     E. On December 31, 1991, MTML was dissolved and its assets were distributed
to Assignee, Beyar and Distributee including the rights of MTML contained in
Section 3 of the Assignment Agreement.

<PAGE>   2

     NOW, THEREFORE, in consideration of the mutual conditions, covenants and
agreements contained herein and to induce Medtronic to enter into the Merger
Agreement, the parties hereto agree as follows:

     1. Section 3 of the Assignment Agreement is hereby deleted in its entirety
and the following Section 3 (compromised of the following Paragraphs 3.1 and
3.2) are inserted in lieu thereof and the Assignment Agreement is amended
thereby:

           "3.1. InStent shall pay royalties to MTML or its designees on
      all sales by InStent of products that incorporate components using
      the technology covered by claims under one or more of the patents
      listed in Exhibit A annexed hereto or under one or more patents
      resulting from a patent application listed in Exhibit A attached
      hereto.  The royalty rate shall be 3% of any sales of such
      products to third parties (it being understood that the royalty
      payable on any one product shall not exceed such 3% rate
      regardless of the number of patents or patent claims covering such
      product), after deduction therefrom of returned products, sales
      commissions payable to third parties, freight and insurance
      expenses, other transportation charges, duties, excise tax, value
      added tax, sales tax and other similar taxes, relating thereto.
      The foregoing royalties shall be payable only with respect to
      sales of such products prior to the sixth anniversary of this
      Second Amendment to Assignment Agreement.  Notwithstanding
      anything to the contrary herein, the total royalties payable under
      this Paragraph 3.1 shall not exceed $2,000,000 in the aggregate;
      provided however, in the event the cumulative amount of royalties
      paid from the date hereof is equal to $2,000,000, then InStent
      shall pay an additional royalty of $1,000,000.

      3.2 Royalties will be paid quarterly within thirty (30) days of each
      calendar quarter.  Royalties payable under Paragraph 3.1 of this Section
      3 shall accrue if not paid; provided, however, this shall in no way limit
      InStent's obligation to make due and punctual payment of such royalties."

      3.3 The parties hereto agree that the royalties payable pursuant to this
      Section 3 are payable to the following individuals at the following
      addresses and in the following percentages:


                    Payee and Address  Percentage of Royalty
                    -----------------  ---------------------

                    Mordechay Beyar          37.5%
                    Assignee                 50%
                    Distributee              12.5%


     2. This Agreement shall take effect as of the Effective Date of the
Merger.  In the event the Merger Agreement shall terminate, then this Agreement
shall automatically terminate without any further act of the parties hereto and
shall be of no further force or effect.

                                     -2-

     IN WITNESS WHEREOF, the parties hereto have executed this Amendment
Agreement on the date and year first above written.

                                  InSTENT INC.

                                    FORM OF

                          CHANGE IN CONTROL AGREEMENT


         THIS AGREEMENT is made by and between InStent Inc., a Delaware
corporation (hereinafter called the "Company") and __________________ (the
"Executive"), as of  the ____ day of ______________, 1996 (the "Effective
Date").
                                   RECITALS:

         WHEREAS, the Executive is currently employed by the Company;

         WHEREAS, the Board of Directors of the Company (the "Board") has
determined that it is in the best interests of the Company and its stockholders
to reinforce and encourage the continued attention and dedication of certain
officers and senior managers of the Company, including the Executive, to their
assigned duties;

         WHEREAS, the existence of this Agreement with the Executive and any
similar agreements with other employees of the Company shall not be construed
to imply that any successors to their respective positions or offices (or any
other employees) would ever be entitled to severance benefits similar to those
provided thereunder; and

         WHEREAS, this Agreement sets forth the minimum severance compensation
that the Executive will receive from the Employer (as defined below) if the
Executive's employment with such Employer terminates under one of the
circumstances described herein in connection with or following a Change in
Control (as defined below).
<PAGE>   2


         NOW, THEREFORE, in consideration of the mutual covenants and
conditions herein contained and in further consideration of services performed
and to be performed by the Executive for the Employer (as defined below) and,
the parties hereto agree as follows:

                                   AGREEMENT

         1.      Certain Definitions.  For purposes of this Agreement, the
terms defined above and the following terms have the meanings indicated:

        (a)     Company.  "Company" means InStent Inc.

        (b)     Employer.  "Employer" means the Company; and shall also include
    any other entity that (i) employs the Executive immediately after a Change
    in Control, (ii) is a successor to or assignee of the business and/or
    assets of the Company and (iii) either executes and delivers the agreement
    provided for in Section 5 or otherwise becomes or remains bound by all the
    terms and provisions of this Agreement by operation of law.

        (c)     Change in Control.  A "Change in Control" of the Company shall
    occur if any person (as defined in Sections 3 (a) (9) and 13(d)(3) of the
    '34 Act, as defined below) becomes the "beneficial owner" (as defined in
    Rule 13d-3 promulgated pursuant to the '34 Act), directly or indirectly, of
    thirty percent (30%) or more of combined voting power of the then
    outstanding securities of the Company; provided, however, that no Change in
    Control shall be deemed to occur if such person:

                (i)     includes any individual, corporation or other entity
         (or any Affiliate thereof, as defined below) that is now the
         beneficial owner of at least five percent (5%) of such securities; or

                                      2
<PAGE>   3

                (ii)    became a beneficial owner of such securities in a
         transaction after which the Company remains as the survivor and  the
         majority of the members of the Board remain such members after the
         closing of the transaction.

        For purposes of this subsection (b), the term " '34 Act" shall mean the
    Securities Exchange Act of 1934, as amended; and the term "Affiliate" shall
    mean any individual, corporation or other entity that controls, is
    controlled by or is under common control with (as applicable) any other
    individual, corporation or other entity referred to herein.

        (d)     Cause.  In the case of a discharge from employment, the term
    "Cause" shall mean:

                (i)     the willful and continued failure by the Executive to
         substantially perform his or her duties under this Agreement or any
         other employment agreement between the Executive and  the Company
         (other than any such failure resulting from the Executive's incapacity
         due to physical or mental illness or any such actual or anticipated
         failure after the issuance of a Notice of Termination by the Executive
         for Good Reason), after a written demand for substantial performance
         is delivered by the Employer that specifically identifies the manner
         in which the Employer believes the Executive has not substantially
         performed his or her duties; or

                (ii)    the willful engaging by the Executive in misconduct
         that is materially injurious to the Employer, monetarily or otherwise. 
         No act, or failure to act, on the Executive's part shall be considered
         "willful" unless done, or omitted to be done, by him or her not in
         good faith and without reasonable belief that his or her action or
         omission was in the best interest of the Employer.


                                      3
<PAGE>   4

        Notwithstanding the foregoing, the Executive shall not be deemed to
    have been terminated for Cause without (x) a reasonable advance written
    notice to the Executive, given before the delivery of a Notice of
    Termination and setting forth the reasons for the Employer's intention to
    terminate for Cause; (y) a reasonable opportunity for the Executive to
    promptly cure any alleged conduct, condition or injury (to the extent it is
    curable) or disprove its existence; and (z) delivery to the Executive of a
    Notice of Termination from the Employer stating that, in the good faith
    opinion of the Employer, the Executive was guilty of conduct set forth
    above in clause (i) or (ii) hereof, and specifying the particulars thereof
    in detail.

         (e)     Date of Termination.  "Date of Termination" shall mean:

                (i)     if this Agreement is terminated by the Employer for
         Disability, the date 30 days after Notice of Termination is given to
         the Executive; provided; however, that such date shall not have been
         delayed pursuant to the following clause (ii); or

                (ii)    if the Executive's employment is terminated by the
         Employer for any other reason, the date on which a Notice of
         Termination is delivered to the Executive or any later date specified
         in such Notice.

        (f)     Disability. "Disability" shall mean the Executive's incapacity
    due to physical or mental illness to substantially perform his or her
    duties on a full-time basis for six consecutive months.  If the Executive
    does not agree with a determination to terminate him or her because of
    Disability, the question of the Executive's Disability shall be subject to
    the certification of a qualified medical doctor agreed to by the Employer
    and the Executive or, in the event of the Executive's incapacity to
    designate a doctor, the Executive's legal


                                      4
<PAGE>   5

    representative.  In the absence of agreement between the Employer and the
    Executive, each party shall nominate a qualified medical doctor and the two
    doctors shall select a third qualified medical doctor, who shall determine
    the question of the Executive's Disability.

        (g)     Effective Date.  The term "Effective Date" shall mean the date
    of this Agreement.

        (h)     Good Reason.   In the case of a resignation from employment,
    the term "Good Reason" shall mean:

                (i)     the assignment of duties or limitation of the
         Executive's responsibilities that are inconsistent with the
         Executive's title, position, duties, responsibilities and status, as
         in effect immediately prior to the Change in Control or the removal
         from or failure to elect the Executive to positions held immediately
         prior to the Change in Control;

                (ii)    a reduction by the Employer in the Executive's base
         salary as in effect on the date hereof or as the same may be increased
         from time to time during the term of this Agreement;

                (iii)   any requirement that the Executive relocate to any
         place outside the Minneapolis-St. Paul, Minnesota metropolitan area,
         except for reasonably required travel by the Executive on the business
         of the Employer to an extent substantially consistent with the
         Executive's business travel obligations at the time of a Change in
         Control of the Company;

                (iv)    any material breach by the Employer of any provision of
         this Agreement;

                                      5
<PAGE>   6

                (v)     if the assets of the Company have been sold in
         connection with a Change in Control, any failure by the Company to
         obtain the assumption of this Agreement by the purchaser pursuant to
         Section 5; or

                (vi)    any purported termination of the Executive's employment
         that is not properly effected hereunder and pursuant to a Notice of
         Termination. For purposes of this Agreement, no such purported
         termination shall be effective.

        (i)     Notice of Termination.  A "Notice of Termination" shall mean a
    written notice, which shall indicate the specific employment termination
    provisions in this Agreement that are relied upon by the party giving such
    notice, and which sets forth in reasonable detail the facts and
    circumstances claimed to provide a basis for the Executive's termination of
    employment.  Any notice of a reason for a proposed termination of the
    Executive's employment for Cause shall not be treated as a Notice of
    Termination.

        Any termination of the Executive's employment by the Employer shall be
    communicated by a Notice of Termination.

         2.      Term.  The term of this Agreement shall commence on the
Effective Date and shall continue in effect until the second anniversary of the
Effective Date.  Commencing on that anniversary, and each anniversary thereof,
the term of this Agreement shall automatically be extended for one additional
year, unless at least three (3) months before any such anniversary the Employer
shall have given the Executive a written notice stating that this Agreement
shall not be so renewed as of the next such anniversary; provided, however,
that if a Change of Control shall have occurred at any time during the term of
this Agreement, such term shall be automatically extended until the end of the
two (2) year  period beginning on the date of such Change of Control and shall
terminate at

                                      6
<PAGE>   7

the end of such period.  To the extent that any obligation of the Employer
hereunder remains unpaid as of the end of such term, this Agreement shall
remain in effect until such obligation is satisfied.

         3.      Minimum Severance Compensation in Connection with a Change of
Control.   In the event that (a) a Change in Control of the Company occurs
during the term of this Agreement; and (b) within the period beginning on the
date the Company announces such Change in Control generally to its employees
and ending twenty-four (24) months after the date of the Change in Control,
either (i) the Employer terminates the Executive's employment for any reason
(or no reason) other than his or her death, Disability or for Cause (it being
understood that a purported termination for Disability or for Cause that is
finally determined not to have such reason, or not to have been properly done,
shall not be a termination for Disability or for Cause), or (ii) the Executive
terminates his or her employment with the Employer for Good Reason, then:

        (A)     the Employer shall pay the Executive any unpaid installment of
    base salary (to the extent earned and accrued through the Date of
    Termination) at the rate in effect at the time the Notice of Termination is
    given, any accrued vacation time (at that same rate) and all other
    pro-rated and unpaid amounts to which the Executive is entitled as of the
    Date of Termination under any compensation plan or program of the Employer,
    including without limitation a portion of the amount (pro-rated based on
    the number of days in the fiscal year or any lesser measurement period)
    that otherwise would be earned under any executive bonus  plan in which the
    Executive is then participating for the year in which occurs such Date of
    Termination; in each case determined by assuming that a bonus under such
    plan would have been earned for the fiscal year or any lesser measurement
    period in which the Date of Termination falls, by performance that reaches
    the previously budgeted level under the plan

                                      7
<PAGE>   8

    for that period; and all of such payments shall be made in a lump sum on or 
    before the fifth day following the Date of Termination;

        (B)     in lieu of any further salary or bonus payments to the
    Executive for periods subsequent to the Date of Termination, the Employer
    shall pay to the Executive as severance  pay an amount equal to the product
    of:

                (i)     the sum of (a) the Executive's annual base salary in
         effect as of the Date of Termination; and (b) the annual amount that
         otherwise would be earned under any executive bonus plan in which the
         Executive is then participating for the Employer's fiscal year in
         which occurs such Date of Termination, determined by assuming that a
         bonus under such plan would have been earned for the fiscal year in
         which the Date of Termination falls, by performance that reaches the
         previously budgeted level under the plan for that year; and

                (ii)    a number that is equal to the number of months
         (including any fraction of a month) remaining between the Date of
         Termination and the second anniversary of the date of the Change of
         Control, divided by twelve; such payment to be made in a lump sum on
         or before the fifth calendar day following the Date of Termination;
         provided, however, that the amount payable to the Executive under this
         Section 2(B) shall be reduced by the sum of any other severance pay
         amounts due the Executive from the Company or the Employer under any
         other plan or agreement; and

        (C)     during the remaining part of the period beginning on the Date
    of Termination and ending on the second anniversary of the date of the
    Change of Control, the Employer shall continue to provide the Executive
    with employee benefits (including without limitation

                                      8
<PAGE>   9

    health benefits, life and disability insurance coverage and any individual
    and family open enrollment options thereunder) that are the same as or
    comparable to those provided to the Executive by the Company and his or her
    dependents  immediately before the Company's announcement of the Change of
    Control, but only to the extent such benefits and enrollment options may be
    provided to former employees and their dependents under rules of the
    Employer's group insurance contracts (if any) and applicable law; provided,
    however, that during such period the Executive pays the same share of the
    costs for such benefits as the share he or she was required to pay before
    such announcement (or, if he or she or any dependent enrolls in new
    coverage during that period, the share applicable to similarly situated
    active employees); and provided further that after such period the Employer
    shall permit Executive and/or his or her dependents to continue such
    coverage at his or her own cost, to the extent required by applicable law,
    by treating the end of such period as the date coverage would otherwise
    terminate for purposes of any such law.

         4.      No Obligation to Mitigate Damages; No Effect on Other
                 Contractual Rights.

        (a)     The Executive shall not be required to mitigate damages or the
    amount of any payment provided for under this Agreement by seeking other
    employment or otherwise, nor shall the amount of any payment provided for
    under this Agreement be reduced by any compensation earned by the Executive
    as the result of employment by another employer after the Date of
    Termination, or otherwise.

        (b)     The provisions of this Agreement, and any payment provided for
    hereunder, shall not reduce any amounts otherwise payable, or in any way
    diminish the Executive's existing rights, or rights which would accrue
    solely as a result of the passage of time, under


                                      9
<PAGE>   10

    any employee benefit plan, incentive plan, Employer securities plan,
    employment  agreement or other contract, plan or arrangement.

5.  Successors to the Company and Employer.

        (a)     The Company and any successor Employer shall require any
    successor or assignee that purchases (other than by a merger of
    corporations) all or substantially all of the business and/or assets of the
    Company or such Employer, by agreement in form and substance reasonably
    satisfactory to the Executive, to expressly, absolutely and unconditionally
    assume and agree to perform this Agreement in the same manner and to the
    same extent that the Company or the successor Employer would be required to
    perform it if no such purchase had taken place.  Any failure of the Company
    or a successor Employer to obtain such agreement prior to the effectiveness
    of any such purchase shall be a material breach of this Agreement and shall
    entitle the Executive to terminate his or her employment hereunder for Good
    Reason.

        (b)     This Agreement shall inure to the benefit of and be enforceable
    by the Company and its successors and assigns, and by the Executive's
    personal and legal representatives, executors, administrators, successors,
    heirs, distributees, devisees and legatees.  If the Executive should die
    while any amounts are still payable to him or her hereunder, all such
    amounts, unless otherwise provided herein, shall be paid in accordance with
    the terms of this Agreement to the Executive's beneficiary last designated
    in a writing delivered to the Employer before his or her death, or
    otherwise to the Executive's devisee or legatee under a last will and
    testament or testamentary trust or, if there be none of the foregoing, to
    the Executive's estate.

         7.      Miscellaneous.  No provisions of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in writing signed by the Executive and an authorized officer of the
Employer.  If any party hereto at any time waives any breach of this Agreement
by another party hereto, or waives compliance with any condition or provision
of this Agreement to be performed by another party hereto, such waiver shall
not be

                                     11
<PAGE>   12

deemed a waiver of that provision or condition at any prior or subsequent time,
or any similar or dissimilar provision or condition at the same or any other
time.  No agreements or representations, oral or otherwise, express or impled,
with respect to the subject matter hereof have been made by either party except
as expressly set forth in this Agreement.  This Agreement shall be governed by
and construed in accordance with the laws of the State of Minnesota.

         8.      Validity.  The invalidity or unenforceability of any
provisions of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, which shall remain in full force and
effect.

         9.      Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original, but all of which
together will constitute one and the same instrument.

         10.     Fees and Expenses.  The Employer shall pay all fees and
expenses (including attorney's fees) that the Executive may incur as a result
of the Employer contesting the validity, enforceability or the Executive's
interpretation of, or any determinations under, this Agreement.

         11.     Confidentiality.  The Executive shall retain in confidence any
and all confidential information known to the Executive concerning the Employer
and its business so long as such information is not otherwise publicly
disclosed.

         12.     Employer's Right to Terminate Employment.  Notwithstanding
anything contained in this Agreement to the contrary, the Employer may
terminate the Executive's employment at any time, for any reason or no reason,
except as may be otherwise provided under a separate written employment
agreement (if any) between the Executive and the Employer; and no provision
contained herein shall affect the Employer's ability to terminate the
Executive's employment at any time, with


                                     12
<PAGE>   13

or without Cause.  Nothing in this Agreement shall in any way require the
Employer to provide any of the benefits specified in this Agreement prior to a
Change in Control, nor shall this Agreement be construed in any way to
establish any policies or other benefits for the Executive or any other
employee of the Employer whose employment with the Employer is terminated prior
to a Change in Control.

         IN WITNESS WHEREOF, the parties have executed this Agreement with full
authority as of the Effective Date first above written.
