Item 3.    Source and Amount of Funds or Other Consideration

This Statement relates to the execution of a certain Stock Option Agreement
dated November 29, 1998, between AVE and Medtronic (the "Stock Option
Agreement"), and to the execution of certain Agreements to Facilitate Merger
(the "Agreements to Facilitate Merger") between Medtronic and each of the
following AVE stockholders: John D. Miller; Gregory M. French; W. Kevin Bedsole;
Scott J. Solano; Glenn S. Foley; Craig E. Dauchy; George B. Borkow; John A.
Schiek; Creg W. Dance; Lawrence J. Fassler; Mark C. Brister; W. Scott Wade; Azin
Parhizgar; Richard L. Klein; Peter Walsh; Robert L. Harris and Andrew P. Rasdal.
The Stock Option Agreement and the Agreements to Facilitate Merger were entered
into as an inducement to Medtronic to enter into the Agreement and Plan of
Merger (the "Merger Agreement"), dated November 29, 1998, among Medtronic, AVE
and MAV Merger Corp. ("Merger Subsidiary"), a wholly owned subsidiary of
Medtronic. Pursuant to the Merger Agreement and subject to the conditions set
forth therein, Merger Subsidiary will merge with and into AVE (the "Merger"),
and each issued and outstanding share of Common Stock of AVE will be converted
into the right to receive a number of shares of Medtronic Common Stock, par
value $.10 per share, determined pursuant to the formula set forth in the Merger
Agreement.

Pursuant to the Stock Option Agreement, AVE granted Medtronic the option to
purchase, at an exercise price of $54.00 per share, 12,807,795 shares of AVE
Common Stock, which was represented in the Stock Option Agreement to reflect at
least 19.9% of the AVE Common Stock outstanding on the date of the Stock Option
Agreement's execution. The option described in the Stock Option Agreement (the
"Option") is not exercisable until and unless the occurrence of certain events
related to the termination of the Merger Agreement under certain circumstances.
If the Option becomes exercisable, any shares purchased pursuant to the exercise
of the Option would be made with funds from Medtronic's working capital. If the
Option becomes exercisable, under certain circumstances, Medtronic can, in lieu
of exercising its Option, put such Option to AVE and receive a Cancellation
Amount from AVE in cash therefor.


<PAGE>

Pursuant to the Agreements to Facilitate Merger, each of the persons noted above
agrees to vote all of such person's AVE shares in favor of approval of the
Merger Agreement and the Merger. Copies of the Stock Option Agreement, the form
of the Agreement to Facilitate Merger and the Merger Agreement are included as
Exhibits to this Statement and are incorporated herein by reference. The
foregoing descriptions of such Agreements are qualified in their entirety by
reference to such Exhibits.

Item 4.    Purpose of Transaction

The purpose of the transactions described in Item 3 is to facilitate approval
and consummation of the Merger. Other than in connection with the Merger
described above, Medtronic has no plans or proposals which relate to, or would
result in, any of the matters listed in paragraphs (a) through (j) of Item 4 of
Schedule 13D.

Item 5.    Interest in Securities of the Issuer

(a) and (b) As a result of the Stock Option Agreement, Medtronic may be deemed
to be the beneficial owner of 12,807,795 shares of Common Stock of AVE, and as a
result of the Agreements to Facilitate Merger, Medtronic may be deemed to be the
beneficial owner of 4,788,240 shares of Common Stock of AVE which represent the
shares beneficially owned by the individuals executing such Agreements,
including the shares purchasable upon exercise of options held by such
individuals that are currently exercisable or become exercisable within sixty
days. Such 17,596,035 shares covered by the Stock Option Agreement and
Agreements to Facilitate Merger would represent approximately 22.7% of the
shares of AVE (based on the number of shares of AVE Common Stock outstanding on
November 29, 1998, as represented to Medtronic by AVE plus the 12,807,795 shares
subject to the Stock Option Agreement, plus the number of shares underlying
options that are currently exercisable or become exercisable within 60 days of
November 29, 1998). Nothing herein, however, shall be deemed to be an admission
by Medtronic that it beneficially owns any of the shares covered by the Stock
Option Agreement or the Agreements to Facilitate Merger, and Medtronic hereby
disclaims beneficial ownership of all shares covered by such Agreements. To the
knowledge of the reporting person, no other person named in Item 2 beneficially
owns any AVE shares.

(c) To the knowledge of the reporting person, the only transactions in the
Common Stock of AVE by any person named in Item 2 above during the past 60 days
are the Stock Option Agreement and Agreements to Facilitate Merger reported in
Item 3 above.

(d) No other person (other than the AVE stockholders who have signed an
Agreement to Facilitate Merger in the case of the shares covered by such
stockholders' Agreement to Facilitate Merger) is known to have the right to
receive or the power to direct the receipt of dividends from, or the proceeds of
the sale of, the subject securities.

(e)      Not applicable.

Item 6.    Contracts, Arrangements, Understandings or Relationships with Respect
           to Securities of the Issuer.

See Item 3 for a description of the Stock Option Agreement, Agreements to
Facilitate Merger and Merger Agreement.

         B                 Form of Agreement to Facilitate Merger

                             STOCK OPTION AGREEMENT


         THIS AGREEMENT is dated as of November 29, 1998, between Medtronic,
Inc., a Minnesota corporation ("Grantee"), and Arterial Vascular Engineering,
Inc., a Delaware corporation ("Issuer").

                                    RECITALS

         A. Grantee, Issuer, and MAV Merger Corp., a Delaware corporation and
wholly-owned subsidiary of Grantee ("Merger Subsidiary"), are entering into an
Agreement and Plan of Merger (the "Merger Agreement") which provides, among
other things, that, upon the terms and subject to the conditions thereof, Merger
Subsidiary will be merged with and into Issuer (the "Merger").

         B. As a condition to its willingness to enter into the Merger
Agreement, Grantee has required that Issuer enter into this Agreement, which
provides, among other things, that Issuer grant to Grantee an option to purchase
shares of Issuer's Common Stock, $.001 par value ("Issuer Common Stock"), upon
the terms and subject to the conditions provided for herein.

         NOW, THEREFORE, in consideration of the premises and mutual covenants
and agreements contained in this Agreement and the Merger Agreement, the parties
agree as follows:

         1. Grant of Option. Subject to the terms and conditions of this
Agreement, Issuer hereby grants to Grantee an irrevocable option (the "Option")
to purchase 12,807,795 shares of Issuer Common Stock (the "Option Shares"), in
the manner set forth below, at an exercise price of $54.00 per share of Issuer
Common Stock, subject to adjustment as provided below (the "Option Price").
Issuer represents that the Option Shares represent at least 19.9% of the number
of shares of Issuer Common Stock outstanding on the date hereof. Capitalized
terms used herein but not defined herein shall have the meanings set forth in
the Merger Agreement.

         2.       Exercise of Option.

                  (a) Subject to the terms and conditions of this Agreement,
         Grantee or its designee (which shall be a wholly-owned subsidiary of
         Grantee) may, prior to the Expiration Date (as defined in Section 12
         hereof), exercise the Option, in whole or in part, at any time or from
         time to time on or after the occurrence of an Exercise Event (as
         defined below). As used herein, an "Exercise Event" shall mean (i) the
         occurrence of a termination specified in Section 7.2(a)(i) of the
         Merger Agreement or (ii) the occurrence of all of the events and
         circumstances specified in clauses (A), (B) and (C) of Section
         7.2(a)(ii) of the Merger Agreement; provided, however, that
         notwithstanding anything to the contrary contained in this Agreement,
         if the Option becomes exercisable as a result of the Exercise Event
         referred to in Section 2(a)(ii) hereof, Grantee shall not be entitled
         to exercise the cancellation right referred to below in this Section
         2(a) unless and until all of the events and circumstances specified in
         clauses (A), (B), (C) and (D) of Section 7.2(a)(ii) of the Merger
         Agreement shall have occurred.


<PAGE>

                  (b) In the event Grantee wishes to exercise the Option at such
         time as the Option is exercisable, Grantee shall deliver written notice
         (the "Exercise Notice") to Issuer exercising the Option and specifying
         the total number of Option Shares it wishes to purchase, and a date and
         time for the closing of such purchase (a "Closing") not less than five
         nor more than 30 business days after the later of (i) the date such
         Exercise Notice is given and (ii) the expiration or termination of any
         applicable waiting period under the Hart-Scott-Rodino Antitrust
         Improvements Act of 1976, as amended (the "HSR Act"). Subject to the
         proviso at the end of Section 2(a) hereof, when this Option is
         exercisable, Grantee, in lieu of exercising the Option, shall have the
         right at any time thereafter prior to the Expiration Date to request in
         writing that Issuer pay, and promptly (but in any event not more than
         five business days) after Grantee makes such request, Issuer shall,
         subject to Section 2(c) below, pay to Grantee by certified check,
         official bank check or wire transfer pursuant to Grantee's
         instructions, in cancellation of the Option, an amount in cash (the
         "Cancellation Amount") equal to (i) the greater of

                           (x) the excess, if any, over the Option Price of the
                  greater of (A) the last sale price of a share of Issuer Common
                  Stock as reported on the Nasdaq National Market (or other
                  United State national exchange upon which Issuer's Common
                  Stock is traded) on the last trading day prior to the date of
                  the Exercise Notice, (B) the highest price per share of Issuer
                  Common Stock offered to be paid or paid in connection with any
                  Alternative Transaction occurring after the date hereof and
                  prior to the Expiration Date, and (C) in the case of any
                  Alternative Transaction structured as an asset acquisition,
                  the highest net consideration to be distributed to the
                  stockholders of the Company in any such transaction or
                  proposed transaction occurring after the date hereof and prior
                  to the Expiration Date after, among any other payments and
                  deductions, payment of all indebtedness of the Company not
                  being assumed, divided by the number of shares of Issuer
                  Common Stock outstanding on a fully diluted basis, and

                           (y) $150,000,000 divided by the initial number of
                  Option Shares covered by the Option,

         multiplied by (ii) the number of Option Shares then covered by the
         Option; provided, however, that the Cancellation Amount shall be
         reduced (but not below zero) to the extent necessary so that the sum of
         the termination fee described in Section 7.2(a) of the Merger Agreement
         (the "Termination Fee") paid to Grantee, the Option Share Profit (as
         defined below) not remitted to Issuer pursuant to Section 2(c) hereof,
         the Section 5 Repurchase Consideration (as defined below) paid to
         Grantee and the Cancellation Amount shall not exceed $150,000,000. If
         all or a portion of the price per share of Issuer Common Stock offered,
         paid, or payable or the aggregate consideration offered, paid, or
         payable for the assets of Issuer, each as contemplated by the preceding
         sentence, consists of noncash consideration, such price or aggregate

<PAGE>

         consideration shall be the cash consideration, if any, plus the fair
         market value of the noncash consideration as mutually determined by the
         investment bankers of Issuer and the investment bankers of Grantee. In
         no event shall (i) the Cancellation Amount exceed $150,000,000 or (ii)
         the sum of the Termination Fee paid, the Option Share Profit not
         remitted to Issuer pursuant to Section 2(c) hereof, the Section 5
         Repurchase Consideration paid and the Cancellation Amount paid exceed
         $150,000,000.

                  (c) In the event that Grantee at any time sells, pledges, or
         otherwise disposes of (including, without limitation, by merger or
         exchange) any of the Option Shares (a "Sale"), or in the event that any
         Cancellation Amount or Section 5 Repurchase Consideration is paid to
         Grantee or any Option Share Profit is received by Grantee (and not
         required to be remitted to Issuer pursuant to this Section 2(c)), then
         any Termination Fee due and payable by Issuer shall be reduced to the
         extent necessary so that the sum of

                           (v) the Termination Fee;

                           (w) any Cancellation Amount paid to Grantee;

                           (x) any Section 5 Repurchase Consideration paid to
                  Grantee;

                           (y) the amount received (whether in cash, loan
                  proceeds, securities, or otherwise) by Grantee in such Sale
                  less the exercise price of such Option Shares sold in the Sale
                  (the "Option Share Profit") and not remitted to Issuer
                  pursuant to this Section 2(c); and

                           (z) Option Share Profit received in connection with
                  any prior sales of Option Shares and not remitted to Issuer
                  pursuant to this Section 2(c),

         shall not exceed $150,000,000. Grantee shall remit to Issuer, within
         ten business days after completion of any Sale, the amount, if any, by
         which the Option Share Profit from such Sale which, when added to the
         Termination Fee previously paid, the Cancellation Amount previously
         paid, the Section 5 Repurchase Consideration previously paid and the
         Option Share Profit from prior sales of Option Shares not remitted to
         Issuer pursuant to this Section 2(c), exceeds $150,000,000.

         3. Payment of Option Price and Delivery of Certificate. Any Closings
under Section 2 hereof shall be held at the principal executive offices of
Issuer, or at such other place as Issuer and Grantee may agree. At any Closing
hereunder, (a) Grantee or its designee will make payment to Issuer of the
aggregate price for the Option Shares being so purchased by delivery of a
certified check, official bank check, or wire transfer of funds pursuant to
Issuer's instructions payable to Issuer in an amount equal to the product
obtained by multiplying the Option Price by the number of Option Shares to be
purchased, and (b) upon receipt of such payment (and the satisfaction or waiver
of the conditions set forth in Section 10 hereof) Issuer will deliver to Grantee
or its designee (which shall be a wholly-owned subsidiary of Grantee) a
certificate or certificates representing the number of validly issued, fully
paid, and nonassessable Option Shares so purchased, in the denominations and
registered in such names (which shall be Grantee or a wholly-owned subsidiary of
Grantee) designated in writing to Issuer by Grantee.


<PAGE>

         4.       Registration and Listing of Option Shares.

                  (a) Issuer agrees to use commercially reasonable efforts to
         (i) effect as promptly as possible upon the request of Grantee and (ii)
         cause to become and remain effective for a period of not less than six
         months (or such shorter period as may be necessary to effect the
         distribution of any Option Shares specified in such request) the
         registration under the 1933 Act, and any applicable state securities
         laws, of the resale of all or any part of the Option Shares as may be
         specified in such request; provided, however, that (A) Grantee shall
         have the right to select the managing underwriter for any such offering
         after consultation with Issuer, which managing underwriter shall be
         reasonably acceptable to Issuer, (B) Grantee shall not be entitled to
         more than two effective registration statements hereunder, and (C)
         Grantee shall not be entitled to request such a registration statement
         within a period of one year after the effective date of a registration
         statement in which Grantee included or was entitled to include all or a
         portion of the Option Shares. The obligations of Issuer hereunder to
         file a registration statement and to maintain its effectiveness may be
         suspended for one or more periods of time not exceeding 90 days in the
         aggregate in any one year period if the Board of Directors of Issuer
         shall have determined in good faith that the filing of such
         registration or the maintenance of its effectiveness would require
         disclosure of nonpublic information that would materially and adversely
         affect Issuer. Upon receipt of notice of the happening of any event as
         a result of which any registration statement, prospectus, prospectus
         supplement, or any document incorporated by reference in any of the
         foregoing, contains any untrue statements of material fact or fails or
         omits to state any material fact required to be stated therein or
         necessary to make the statements therein, in light of the circumstances
         under which they are made, not misleading, Grantee shall forthwith
         discontinue the disposition of any shares under such registration
         statement, prospectus or prospectus supplement until Grantee receives
         from Issuer copies (which subject to the limitations on suspension set
         forth above shall promptly be made available by Issuer) of an amended
         or supplemented registration statement, prospectus or supplement so
         that, as thereafter delivered to purchases of such shares, such
         registration statement, prospectus or prospectus supplement shall not
         contain any untrue statement of material fact or fail or omit to state
         any material fact required to be stated therein or necessary to make
         the statements therein, in light of the circumstances under which they
         are made, not misleading.

                  (b) In addition to such demand registrations, if Issuer
         proposes to effect a registration of Issuer Common Stock for its own
         account or for the account of any other stockholder of Issuer (other
         than in connection with (i) employee stock option plans or other
         employee or consultant benefit arrangements or (ii) corporate or
         business acquisitions), Issuer will give prompt written notice to
         Grantee of its intention to do so and shall use commercially reasonable
         efforts to include therein all Option Shares requested by Grantee to be

<PAGE>

         so included; provided, however, that, if the managing underwriter of
         the offering covered by such registration advises Issuer that in its
         opinion the number of Option Shares requested to be included in such
         registration exceeds the number that can be sold in such offering,
         Issuer shall, after fully including therein all securities to be sold
         by Issuer, include the shares requested to be included therein by
         Grantee pro rata (based on the number of shares intended to be included
         therein) with the shares intended to be included therein by persons
         other than Issuer. In connection with any offering, sale and delivery
         of Option Shares pursuant to a registration statement effected pursuant
         to this Section 4(b), Grantee shall provide Issuer and each underwriter
         of the offering with customary representations, warranties and
         covenants. No registration effected under this Section 4(b) shall
         relieve Issuer of its obligations to effect demand registrations under
         Section 4(a) hereof.

                  (c) Registrations effected under this Section 4 shall be
         effected at Issuer's expense, including the fees and expenses of
         counsel to Grantee, but excluding underwriting discounts and
         commissions to brokers or dealers. In connection with each registration
         under this Section 4, Issuer shall indemnify and hold Grantee, its
         underwriters, and each of their respective affiliates harmless against
         any and all losses, claims, damage, liabilities, and expenses
         (including, without limitation, investigation expenses and fees and
         disbursements of counsel and accountants), joint or several, to which
         Grantee, its underwriters, and each of their respective affiliates may
         become subject, under the 1933 Act or otherwise, insofar as such
         losses, claims, damages, liabilities, or expenses (or actions in
         respect thereof) arise out of or are based upon an untrue statement or
         alleged untrue statement of a material fact contained in any
         registration statement (including any prospectus therein), or any
         amendment or supplement thereto, or arise out of or are based upon the
         omission or alleged omission to state therein a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading, other than such losses, claims, damages, liabilities, or
         expenses (or actions in respect thereof) that arise out of or are based
         upon an untrue statement or alleged untrue statement of a material fact
         contained in written information furnished by Grantee to Issuer
         expressly for use in such registration statement.

                  (d) In connection with any registration statement pursuant to
         this Section 4, Grantee agrees to furnish Issuer with such information
         concerning itself and the proposed sale or distribution as shall
         reasonably be required in order to ensure compliance with the
         requirements of the 1933 Act. In addition, Grantee shall indemnify and
         hold Issuer, its underwriters and each of their respective affiliates
         harmless against any and all losses, claims, damages, liabilities, and
         expenses (including, without limitation, investigation expenses and
         fees and disbursements of counsel and accountants), joint or several,
         to which Issuer, its underwriters, and each of their respective
         affiliates may become subject under the 1933 Act or otherwise, insofar
         as such losses, claims, damages, liabilities, or expenses (or actions
         in respect thereof) arise out of or are based upon an untrue statement
         or alleged untrue statement of a material fact contained in written
         information furnished by Grantee to Issuer expressly for use in such
         registration statement.


<PAGE>

                  (e) Upon the issuance of Option Shares hereunder, Issuer will
         use commercially reasonable efforts promptly to cause such Option
         Shares to be quoted on Nasdaq or on such national or other exchange on
         which the shares of Issuer Common Stock are at the time listed or
         quoted.

         5. Repurchase at the Option of Issuer.

                  (a) At the request of Issuer at any time during the 180-day
         period commencing on the 180th day after the date on which the Option
         was first exercised in whole or in part (the "Call Period"), Issuer may
         repurchase from Grantee, and Grantee shall sell to Issuer, up to 95% of
         the shares of Issuer Common Stock acquired by Grantee pursuant hereto
         and with respect to which Grantee has beneficial ownership at the time
         of such repurchase at a price per share equal to the Repurchase Price
         (defined below) per share in respect of the shares so acquired (such
         price per share multiplied by the number of shares of Issuer Common
         Stock to be repurchased pursuant to this Section 5 being herein called
         the "Section 5 Repurchase Consideration"). The date on which Issuer
         exercises its rights under this Section 5 by delivering its request to
         Grantee is referred to as the "Issuer Request Date." Issuer's rights
         under this Section 5 shall be suspended (and the Call Period shall be
         extended accordingly) during any period when the exercise of such
         rights would subject Grantee to liability pursuant to Section 16(b) of
         the Exchange Act by reason of the issuance of the Option, any
         adjustment pursuant to Section 11 hereof, or the Grantee's purchase of
         any Option Shares hereunder. "Repurchase Price" per share shall be the
         sum of (i) the Option Price plus (ii) the amount that results from
         dividing (A) $150,000,000 minus the sum of (I) any Termination Fee paid
         to Grantee, (II) any Option Share Profit not remitted to Issuer
         pursuant to Section 2(c) hereof, (III) any Section 5 Repurchase
         Consideration paid to Grantee pursuant to this Section 5 plus (IV) any
         Cancellation Amount paid to Grantee by (B) the initial number of Option
         Shares covered by the Option, provided, however, that notwithstanding
         anything to the contrary contained in this Agreement, if the Option
         becomes exercisable as a result of the Exercise Event referred to in
         Section 2(a)(ii) hereof, the Repurchase Price shall be equal to the
         Option Price if the repurchase of shares pursuant to this Section 5 is
         completed before the occurrence of the event specified in clause (D) of
         Section 7.2(a)(ii) of the Merger Agreement.

                  (b) The Section 5 Repurchase Consideration to be paid in
         connection with any repurchase request shall be reduced to the extent
         necessary so that the sum of

                           (v) the Section 5 Repurchase Consideration to be paid
                  in the repurchase which is the subject of Issuer's repurchase
                  request at issue;

                           (w) any Section 5 Repurchase Consideration previously
                  paid;

                           (x) any Cancellation Amount paid to Grantee;

                           (y) any Termination Fee paid to Grantee; and


<PAGE>

                           (z) any Option Share Profit not remitted to Issuer
                  pursuant to Section 2(c),

         shall not exceed $150,000,000.

                  (c) If Issuer exercises its rights under this Section 5,
         Issuer shall, within five business days after the Issuer Request Date,
         pay the Section 5 Repurchase Consideration, subject to reduction as
         provided in Section 5(b) above, in immediately available funds, and
         Grantee shall surrender to Issuer certificates evidencing the shares of
         Issuer Common Stock purchased hereunder, and Grantee shall warrant to
         Issuer that, immediately prior to the repurchase thereof pursuant to
         this Section 5, Grantee had sole record and beneficial ownership of
         such shares and that such shares were then held free and clear of all
         Encumbrances.

         6. Representations and Warranties of Issuer. Issuer hereby represents
and warrants to Grantee as follows:

                  (a) Issuer is a corporation duly organized, validly existing,
         and in good standing under the laws of the State of Delaware and has
         all requisite corporate power and authority to enter into and perform
         this Agreement.

                  (b) The execution and delivery of this Agreement by Issuer and
         the consummation by Issuer of the transactions contemplated hereby have
         been duly and validly authorized by the Board of Directors of Issuer,
         and except to the extent of any Nasdaq requirements, no other corporate
         proceedings on the part of Issuer are necessary to authorize this
         Agreement or to consummate the transactions contemplated hereby. The
         Board of Directors of Issuer has duly approved the issuance and sale of
         the Option Shares, upon the terms and subject to the conditions
         contained in this Agreement, and the consummation of the transactions
         contemplated hereby. This Agreement has been duly and validly executed
         and delivered by Issuer and, assuming this Agreement has been duly and
         validly authorized, executed, and delivered by Grantee, constitutes a
         valid and binding obligation of Issuer enforceable against Issuer in
         accordance with its terms, subject to bankruptcy, insolvency,
         reorganization, moratorium, or other similar laws affecting or relating
         to creditors, rights generally; the availability of injunctive relief
         and other equitable remedies and general principles of equity; and
         limitations imposed by law on indemnification for liability under
         federal securities laws.

                  (c) Except as may be required in accordance with Nasdaq
         requirements, Issuer has taken all necessary action to authorize and
         reserve for issuance and to permit it to issue, and at all times from
         the date of this Agreement through the date of expiration of the Option
         will have reserved for issuance upon exercise of the Option, such
         number of authorized shares of Issuer Common Stock as is equal to the
         number of Option Shares (or such other amount as may be required
         pursuant to Section 11 hereof), each of which, upon issuance pursuant
         to this Agreement and when paid for as provided herein, will be validly

<PAGE>

         issued, fully paid, and nonassessable, and shall be delivered free and
         clear of all claims, liens, charges, encumbrances, and security
         interests and not subject to any preemptive rights (collectively,
         "Encumbrances").

                  (d) Except as may be required in accordance with Nasdaq
         requirements, the execution, delivery, and performance of this
         Agreement by Issuer and the consummation by it of the transactions
         contemplated hereby except as required by the HSR Act (if applicable),
         and, with respect to Section 4, compliance with the provisions of the
         1933 Act and any applicable state securities laws, do not require the
         consent, waiver, approval, license, or authorization of or result in
         the acceleration of any obligation under, or constitute a default
         under, any term, condition, or provision of any charter or bylaw, or
         any indenture, mortgage, lien, lease, agreement, contract, instrument,
         order, judgment, ordinance, regulation, or decree or any restriction to
         which Issuer or any property of Issuer or its subsidiaries is bound,
         except where the failure to obtain such consents, waivers, approvals,
         licenses, or authorizations or where such acceleration or defaults
         could not, individually or in the aggregate, reasonably be expected to
         have a Company Material Adverse Effect.

                  (e) The Company has taken all action and completed all
         amendments, if any, necessary or appropriate so that (i) the Rights
         Agreement dated as of February 26, 1997, as amended, between the
         Company and BankBoston, N.A. (the "Company Rights Agreement"), is
         inapplicable to the transactions contemplated by this Agreement, the
         Agreements to Facilitate Merger, and the Merger Agreement, and (ii) the
         execution of this Agreement, the Agreements to Facilitate Merger, and
         the Merger Agreement, and the consummation of the transactions
         contemplated hereby and thereby, do not and will not (w) result in
         Grantee being an "Acquiring Person" (as such term is defined in the
         Company Rights Agreement), (x) result in the ability of any person to
         exercise any Rights under the Company Rights Agreement, (y) enable or
         require the Rights to separate from the shares of Company Common Stock
         to which they are attached or to be triggered or become exercisable, or
         (z) otherwise result in the occurrence of a "Distribution Date" or
         "Shares Acquisition Date" (as such terms are defined in the Company
         Rights Agreement).

         7. Representations and Warranties of Grantee. Grantee hereby represents
and warrants to Issuer that:

                  (a) Grantee is a corporation duly organized, validly existing,
         and in good standing under the laws of the State of Minnesota and has
         all requisite corporate power and authority to enter into and perform
         this Agreement.

                  (b) The execution and delivery of this Agreement by Grantee
         and the consummation of the transactions contemplated hereby have been
         duly and validly authorized by the Board of Directors of Grantee, and
         no other corporate proceedings on the part of Grantee are necessary to
         authorize this Agreement or to consummate the transactions contemplated
         hereby. This Agreement has been duly and validly executed and delivered
         by Grantee and, assuming this Agreement has been duly executed and

<PAGE>

         delivered by Issuer, constitutes a valid and binding obligation of
         Grantee enforceable against Grantee in accordance with its terms,
         subject to bankruptcy, insolvency, reorganization, moratorium, or other
         similar laws affecting or relating to creditors' rights generally; the
         availability of injunctive relief and other equitable remedies; and
         limitations imposed by law on indemnification for liability under
         federal securities laws.

                  (c) Grantee or its designee is acquiring the Option and it
         will acquire the Option Shares issuable upon the exercise thereof for
         its own account and not with a view to the distribution or resale
         thereof in any manner not in accordance with applicable law.

         8. Covenants of Grantee. Grantee agrees not to transfer or otherwise
dispose of the Option or the Option Shares, or any interest therein, except in
compliance with the 1933 Act and any applicable state securities law. Grantee
further agrees to the placement of the following legend on the certificates
representing the Option Shares (in addition to any legend required under
applicable state securities laws):

                  "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER EITHER (1) THE SECURITIES ACT OF 1933, AS
                  AMENDED (THE "ACT"), OR (2) ANY APPLICABLE STATE LAW GOVERNING
                  THE OFFER AND SALE OF SECURITIES. NO TRANSFER OR OTHER
                  DISPOSITION OF THESE SHARES, OR OF ANY INTEREST THEREIN, MAY
                  BE MADE EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
                  UNDER THE ACT AND SUCH OTHER STATE LAWS OR PURSUANT TO
                  EXEMPTIONS FROM REGISTRATION UNDER THE ACT, SUCH OTHER STATE
                  LAWS, AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER."

         9. Commercially Reasonable Efforts. Grantee and Issuer shall take, or
cause to be taken, all reasonable action to consummate and make effective the
transactions contemplated by this Agreement, including, without limitation,
commercially reasonable efforts to obtain any necessary consents of third
parties and governmental agencies (including, without limitation, compliance
with any Nasdaq approvals or requirements) and the filing by Grantee and Issuer
promptly after the date hereof of any required HSR Act notification forms and
the documents required to comply with the HSR Act.

         10. Certain Conditions. The obligation of Issuer to issue Option Shares
at a Closing under this Agreement after exercise of the Option shall be subject
to the satisfaction or waiver of the following conditions:

                  (a) any waiting periods applicable to the acquisition of the
         Option Shares by Grantee pursuant to this Agreement under the HSR Act
         shall have expired or been terminated;


<PAGE>

                  (b) the representations and warranties of Grantee made in
         Section 6 of this Agreement shall be true and correct in all material
         respects as of the date of the Closing for the issuance of such Option
         Shares;

                  (c) no order, decree, or injunction entered by any court of
         competent jurisdiction or governmental, regulatory, or administrative
         agency or commission in the United States shall be in effect that
         prohibits the exercise of the option or acquisition of Option Shares
         pursuant to this Agreement; and

                  (d) compliance with any Nasdaq approvals or requirements.

         11. Adjustments Upon Changes in Capitalization. In the event of any
change in the number of issued and outstanding shares of Issuer Common Stock by
reason of any stock dividend, stock split, recapitalization, merger, rights
offering, share exchange, or other change in the corporate or capital structure
of Issuer, Grantee shall receive, upon exercise of the Option, the stock or
other securities, cash, or property to which Grantee would have been entitled if
Grantee had exercised the Option and had been a holder of record of shares of
Issuer Common Stock on the record date fixed for determination of holders of
shares of Issuer Common Stock entitled to receive such stock or other
securities, cash, or property at the same aggregate price as the aggregate
Option Price of the Option Shares.

         12. Expiration. The Option shall expire at the earlier of (a) the
Effective Time (as defined in the Merger Agreement), (b) one year after the
termination of the Merger Agreement in accordance with the terms thereof in the
event Section 7.2(a)(i) of the Merger Agreement applies, or one year after the
event specified in Section 7.2(a)(ii)(D) of the Merger Agreement occurs in the
event such Section 7.2(a)(ii) applies, or (c) termination of the Merger
Agreement in accordance with the terms thereof in circumstances under which the
fee specified in Section 7.2 thereof cannot in any circumstances become payable
(such expiration date is referred to as the "Expiration Date").

         13.      General Provisions.

                  (a) Survival. All of the representations, warranties, and
         covenants contained herein shall survive each Closing and shall be
         deemed to have been made as of the date hereof and as of the date of
         each Closing.

                  (b) Further Assurances. If Grantee exercises the Option, or
         any portion thereof, in accordance with the terms of this Agreement,
         Issuer and Grantee will execute and deliver all such further documents
         and instruments and use commercially reasonable efforts to take all
         such further action as may be necessary in order to consummate the
         transactions contemplated thereby.

                  (c) Severability. It is the desire and intent of the parties
         that the provisions of this Agreement be enforced to the fullest extent
         permissible under the law and public policies applied in each
         jurisdiction in which enforcement is sought. Accordingly, in the event

<PAGE>

         that any provision of this Agreement would be held in any jurisdiction
         to be invalid, prohibited, or unenforceable for any reason, such
         provision, as to such jurisdiction, shall be ineffective, without
         invalidating the remaining provisions of this Agreement or affecting
         the validity or enforceability of such provision in any other
         jurisdiction. Notwithstanding the foregoing, if such provision could be
         more narrowly drawn so as not be invalid, prohibited, or unenforceable
         in such jurisdiction, it shall, as to such jurisdiction, be so narrowly
         drawn, without invalidating the remaining provisions of this Agreement
         or affecting the validity or enforceability of such provision in any
         other jurisdiction.

                  (d) Assignment. This Agreement shall be binding on and inure
         to the benefit of the parties hereto and their respective successors
         and assigns; provided, however, that Issuer shall not be entitled to
         assign or otherwise transfer any of its rights or obligations
         hereunder, and Grantee shall not be entitled to assign or otherwise
         transfer the Option or any of its rights or obligations hereunder.

                  (e) Specific Performance. The parties agree and acknowledge
         that in the event of a breach of any provision of this Agreement, the
         aggrieved party would be without an adequate remedy at law. The parties
         therefore agree that in the event of a breach of any provision of this
         Agreement, the aggrieved party may elect to institute and prosecute
         proceedings in any court of competent jurisdiction to enforce specific
         performance or to enjoin the continuing breach of such provision, as
         well as to obtain damages for breach of this Agreement. By seeking or
         obtaining any such relief, the aggrieved party will not be precluded
         from seeking or obtaining any other relief to which it may be entitled.

                  (f) Amendments. This Agreement may not be modified, amended,
         altered, or supplemented except upon the execution and delivery of a
         written agreement executed by Grantee and Issuer.

                  (g) Notices. All notices, requests, claims, demands, and other
         communications hereunder shall be in writing and shall be deemed to be
         sufficient if contained in a written instrument and shall be deemed

                         AGREEMENT TO FACILITATE MERGER

DATE:    ____________, 1998

PARTIES:

                  Medtronic, Inc.,                        (hereinafter "Parent")
                  a Minnesota corporation

                           and

                  ----------------------------,
                  an individual officer and/or director
                  of Arterial Vascular Engineering, Inc.
                                                     (hereinafter "Stockholder")

RECITALS:

         A. Stockholder is the legal or beneficial owner of shares of Common
Stock of Arterial Vascular Engineering, Inc., a Delaware corporation (the
"Company"), and the holder of options, warrants, or other rights to acquire
shares of Company Common Stock.

         B. Parent, the Company, and a wholly-owned subsidiary of Parent are
entering, or have entered, into an Agreement and Plan of Merger (the "Merger
Agreement") pursuant to which it is proposed that Parent's subsidiary will merge
with and into the Company (the "Merger") and as a result of which the
outstanding shares of Company Common Stock shall be converted into Parent Common
Stock.

         C. Stockholder deems it to be in Stockholder's best interest and in the
best interests of the Company and all other stockholders of the Company that the
Merger Agreement be approved, ratified, and confirmed by the stockholders of the
Company, and it is a condition to Parent's execution of the Merger Agreement
that Stockholder enter into this Agreement.

         D. It is understood and acknowledged by Stockholder that Parent's
execution of the Merger Agreement is being done in reliance, in part, upon the
contemporaneous or prompt subsequent execution and delivery of this Agreement,
that Parent will incur substantial expenses proceeding toward consummation of
the Merger as contemplated by the Merger Agreement, and that such expenses will
be undertaken, in part, in reliance upon and as a result of the agreements and
undertakings of Stockholder set forth herein.

         NOW, THEREFORE, in consideration of the foregoing, and in order to
induce Parent to execute the Merger Agreement and to proceed as contemplated by
the Merger Agreement toward the consummation of the Merger, and for other good
and valuable consideration, the receipt and adequacy of which is hereby
acknowledged, the parties hereto agree as follows:


<PAGE>

AGREEMENTS:

         1. Vote in Favor of Merger. During the period commencing on the date
hereof and terminating upon the earlier of the effective time of the Merger or
the termination of the Merger Agreement in accordance with its terms,
Stockholder, solely in his or her capacity as a stockholder of the Company
agrees to vote (or caused to be voted) all outstanding shares of Company Common
Stock beneficially owned by Stockholder as of the record date of any meeting of
the stockholders of the Company, and as of the record date of any action by
written consent of the stockholders of the Company in favor of the approval,
consent, and ratification of the Merger Agreement and the Merger. To the extent
inconsistent with the foregoing provisions of this Section 1, Stockholder hereby
revokes any and all previous proxies with respect to any shares of Company
Common Stock that Stockholder owns or has the right to vote. Nothing in this
Agreement shall be deemed to restrict or limit Stockholder's right to act in his
capacity as an officer or director of the Company consistent with his fiduciary
obligations in such capacity.

         2. Representations and Warranties of Stockholder. Stockholder
represents and warrants to Parent that Stockholder has the legal capacity to
enter into and perform all of Stockholder's obligations under this Agreement.
The execution, delivery, and performance of this Agreement by Stockholder will
not violate any other agreement to which Stockholder is a party, including,
without limitation, any voting agreement, stockholders agreement, or voting
trust. This Agreement has been duly executed and delivered by Stockholder and
constitutes a legal, valid, and binding agreement of Stockholder, enforceable in
accordance with its terms, except as the enforcement thereof may be limited by
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium, and
similar laws, now or hereafter in effect.

         3. Successors and Assigns. This Agreement shall be binding upon any
permitted purchasers, donees, pledgees, and other transferees of Company Common
Stock legally or beneficially owned by Stockholder. During the period commencing
on the date hereof and terminating upon the earlier of the effective time of the
Merger or the termination of the Merger Agreement in accordance with its terms,
Stockholder agrees not to make any sales, gifts, transfers, pledges, or other
dispositions of Company Common Stock without first making any such transferee or
pledgee fully aware of the obligations under this Agreement and obtaining such
transferee's or pledgee's written agreement to comply with the terms hereof.

         4. Injunctive Relief. Stockholder agrees that in the event of
Stockholder's breach of any provision of this Agreement, Parent may be without
an adequate remedy at law. Stockholder therefore agrees that in the event of
Stockholder's breach of any provision of this Agreement, Parent may elect to
institute and prosecute proceedings in any court of competent jurisdiction to
enforce specific performance or to enjoin the continuing breach of such
provision, as well as to obtain damages for breach of this Agreement. By seeking
or obtaining any such relief, Parent will not be precluded from seeking or
obtaining any other relief to which it may be entitled.


<PAGE>

         5. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original and all of which
together shall constitute one and the same document.

         6. Further Assurances. Stockholder shall (at Parent's expense) execute
and deliver such additional documents and take such further action as may be
reasonably requested by Parent to enforce Parent's rights under this Agreement.

         7. Third-Party Beneficiaries. Nothing in this Agreement, expressed or
implied, shall be construed to give any person other than the parties hereto any
legal or equitable right, remedy, or claim under or by reason of this Agreement
or any provision contained herein.

         8. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware (regardless of the laws that
might otherwise govern under applicable Delaware principles of conflicts of
laws).

         9. Effectiveness. If this Agreement is executed by Stockholder prior to
the approval of the Merger Agreement by the Company's Board of Directors, then
this Agreement shall be subject to, and shall become effective only upon, the
approval of the Merger Agreement by the Company's Board of Directors and the
execution and delivery of the Merger Agreement by the Company, Parent and
Parent's subsidiary. This Agreement shall terminate upon the earlier of (i)
termination of the Merger Agreement in accordance with its terms, or (ii)
effectiveness of the Merger.

         IN WITNESS WHEREOF, Parent has caused this Agreement to Facilitate
Merger to be executed by its duly authorized officer, and Stockholder has
executed this Agreement, as of the date and year first above written.

                          AGREEMENT AND PLAN OF MERGER

         THIS AGREEMENT is dated as of November 29, 1998, by and among
Medtronic, Inc., a Minnesota corporation ("Parent"), MAV Merger Corp., a
Delaware corporation and wholly owned subsidiary of Parent ("Merger
Subsidiary"), and Arterial Vascular Engineering, Inc., a Delaware corporation
(the "Company").

         WHEREAS, the Boards of Directors of Parent, Merger Subsidiary, and the
Company have approved the merger of Merger 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(a) 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, as a condition to, and upon or immediately following the
execution of, this Agreement, Parent and the Company are entering into the Stock
Option Agreement described in Section 5.13 hereof; 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), Merger 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 Merger 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 Merger 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 on the Closing Date (as
defined in Section 2.1), the Company will file, or cause to be filed, with the
Secretary of State of the State of Delaware a Certificate of Merger for the

<PAGE>

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 the Company, Parent, Merger
Subsidiary or any holder of any share of capital stock of the Company or Merger
Subsidiary:

                  (a) Each share of common stock of the Company, $.001 par value
per share ("Company Common Stock"), issued and outstanding immediately prior
thereto (except for shares referred to in Section 1.3(b) hereof) shall be
converted, subject to Section 1.5(f), into the right to receive a number of
shares (carried out to five decimal places and rounded up if the sixth decimal
place is 5 or greater) (the "Conversion Ratio") of common stock of Parent, par
value $.10 per share (the "Parent Common Stock"), based on the average (rounded
to the nearest full cent, with the cents rounded up if the third decimal place
is 5 or more) of the daily closing sale prices of a share of Parent Common Stock
as reported on the New York Stock Exchange ("NYSE") Composite Tape, as reported
in The Wall Street Journal (the "Parent Average Stock Price"), for the fifteen
consecutive NYSE trading days ending on and including the NYSE trading day that
is two NYSE trading days prior to the Company Stockholders Meeting (as defined
in Section 5.5) (the "Determination Period"), determined as follows:

                           (i) if the Parent Average Stock Price for the
                  Determination Period is greater than $61.20 and less than
                  $74.80, then the Conversion Ratio shall equal $54.00 divided
                  by the Parent Average Stock Price for the Determination
                  Period;

                           (ii) if the Parent Average Stock Price for the
                  Determination Period is equal to or less than $61.20, then the
                  Conversion Ratio shall equal 0.88235; or

                           (iii) if the Parent Average Stock Price for the
                  Determination Period is equal to or greater than $74.80, then
                  the Conversion Ratio shall equal 0.72193.

                  An appropriate adjustment to the Conversion Ratio 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 number of shares or a different class by reason of any
reorganization, reclassification, subdivision, recapitalization, split-up,
combination, exchange of shares, stock dividend or other similar transaction.
Notwithstanding the foregoing, nothing in this section shall be deemed to
constitute authorization or permission for or consent from Parent or Merger
Subsidiary to any reorganization, reclassification, subdivision,
recapitalization, split-up, combination, exchange of shares, or other similar
transaction.

                  (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, Merger Subsidiary,
or any direct or indirect wholly owned subsidiary of Parent or the Company shall
be canceled in accordance with applicable laws without payment of any
consideration therefor and without any conversion thereof.


<PAGE>

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

                  (d) Each share of common stock of Merger Subsidiary, par value
$.01 per share ("Merger 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, par value $.01 per share ("Surviving
Corporation Common Stock").

         1.4 No Appraisal Rights. The parties acknowledge that, pursuant to
Section 262 of the DGCL, no holders of Company Common Stock shall have appraisal
rights in connection with the Merger.

         1.5  Exchange of Company Common Stock.

                  (a) At or prior to the Effective Time, Parent shall cause
Parent's stock transfer agent or such other person as Parent may appoint and is
reasonably satisfactory to the Company to act as exchange agent (the "Exchange
Agent") hereunder. As promptly as practicable after the Effective Time, Parent
shall cause the Exchange Agent to mail to each holder of record (other than
Parent, Merger Subsidiary, the Company, or any wholly owned 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 the Company Certificate(s)
shall pass, only upon delivery of the Company Certificate(s) to the Exchange
Agent) and instructions for such holder's use in effecting the surrender of the
Company Certificates in exchange for certificates representing shares of Parent
Common Stock and cash in lieu of any fractional shares.

                  (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 certificates representing the number of whole shares of Parent Common Stock
into which the shares represented by the Company Certificate(s) shall have been
converted pursuant to Section 1.3(a), (ii) a bank check in the amount of cash
into which the shares represented by the Company Certificate(s) shall have been
converted pursuant to Section 1.5(f) (relating to fractional shares), and (iii)
any dividends or other distributions to which such holder is entitled pursuant
to Section 1.5(c), and the Company Certificate(s) so surrendered shall be
canceled. 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 the 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.


<PAGE>

                  (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 certificates evidencing shares of Parent Common Stock
that are issued upon the surrender for exchange of Company Certificates in
accordance with the terms hereof, together with 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 the shares of Company Common Stock
represented by the surrendered Company Certificates.

                  (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 canceled 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 stockholders of
the Company, except such rights, if any, as they may have pursuant to the DGCL
or this Agreement. 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 a
certificate or certificates evidencing the number of whole shares of Parent
Common Stock into which the shares of Company Common Stock shall have been
converted pursuant to the Merger as provided in Section 1.3(a) hereof, 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 and the right to receive any dividends or
distributions as provided in Section 1.5(c).

                  (f) No fractional shares of Parent Common Stock and no
certificates or scrip therefor, or other evidence of ownership thereof, shall be
issued in connection with the Merger, 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

<PAGE>

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 closing sale price of a share of Parent Common
Stock as reported on the NYSE Composite Tape, as reported in The Wall Street
Journal, on the Closing Date 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.

                  (g) In the event any Company Certificates shall have been
lost, stolen, or destroyed, the Exchange Agent shall issue in respect of such
lost, stolen, or destroyed Company Certificates, upon the making of an affidavit
of that fact by the holder thereof, such shares of Parent Common Stock, cash for
fractional shares, if any, and dividends or other distributions, 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 reasonably 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) The parties hereto acknowledge that each certificate
representing a share of Parent Common Stock issued pursuant to this Article 1
will, pursuant to the Rights Agreement dated as of June 27, 1991, between Parent
and Norwest Bank Minnesota, N.A. (the "Parent Rights Plan"), also represent the
number of Parent preferred share purchase rights associated with one share of
Parent Common Stock at the Effective Time.

         1.6 Exchange of Merger Subsidiary Common Stock. From and after the
Effective Time, each outstanding certificate previously representing shares of
Merger 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 Merger 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 Merger Subsidiary Common Stock,
which shall be canceled.

         1.7  Stock Options.

                  (a) Except as provided in (c) below with respect to the
Company's 1997 Employee Stock Purchase Plan, as amended (the "Company ESPP"),
each option to purchase shares of Company Common Stock that is outstanding at
the Effective Time, whether or not exercisable and whether or not vested (a
"Company Option") shall, without any action on the part of the Company or 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 Options shall be deemed to refer to
Parent. The Company Options assumed by Parent shall be exercisable upon the same
terms and conditions as under the Company Options (including provisions
regarding vesting and the acceleration thereof) except that (i) such Company
Options shall entitle the holder to purchase from Parent the number of shares of

<PAGE>

Parent Common Stock (rounded down to the nearest whole number of such shares)
that equals the product of the Conversion Ratio multiplied by the number of
shares of Company Common Stock subject to such Company Option immediately prior
to the Effective Time, (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, and (iii) the
Company Options shall vest to the extent required pursuant to the current terms
of such Company Options or other agreements as described in Section 1.7 of the
Company Disclosure Schedule (as defined below); provided that if such vesting of
Company Options or other provisions with respect to the Company Options would
jeopardize the Merger being accounted for as a "pooling of interests", then the
Company shall, subject to Parent's written consent not to be unreasonably
withheld, use reasonable best efforts to prevent such vesting or effect of other
provisions. Except to the extent required pursuant to the current terms of such
Company Options or other agreements as described in Section 1.7 of the Company
Disclosure Schedule (as defined below), the Company shall not take any action to
accelerate the vesting of any Company Options. Prior to the Effective Time, the
Board of Directors of Parent shall, for purposes of Rule 16b-3(d)(1) promulgated
under Section 16 of the Securities Exchange Act of 1934, and the rules and
regulations thereunder (the "1934 Act"), specifically approve (i) the assumption
by Parent of the Company Options and (ii) the issuance of Parent Common Stock in
the Merger to directors, officers and stockholders of the Company subject to
Section 16 of the 1934 Act.

                  (b) 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. As
soon as reasonably practicable after the Effective Time (and in any event no
later than five business days after the Effective Time, provided current option
information required therefor is delivered to Parent at the Effective Time),
Parent shall file a registration statement on Form S-8 (or any successor form)
with respect to the shares of Parent Common Stock subject to Company Options and
shall use commercially reasonable efforts to maintain such registration
statement (or any successor form), including the current status of any related
prospectus or prospectuses, for so long as the Company Options remain
outstanding. In addition, Parent shall use commercially reasonable efforts to
cause the shares of Parent Common Stock subject to Company Options to be listed
on the NYSE and such other exchanges as Parent shall determine. Parent shall
take all corporate action necessary to reserve for issuance a sufficient number
of shares of Parent Common Stock for delivery upon exercise of Company Options
pursuant to the terms set forth in this Section 1.7. Parent shall comply with
the terms of the Company Stock Option Plans (as defined in Section 3.3) and use
commercially reasonable efforts to cause those Company Options which qualified
as incentive stock options prior to the Effective Time to continue to qualify as
incentive stock options immediately after the Effective Time.

                  (c) The current offerings in process as of the date of this
Agreement under the Company ESPP shall continue, and shares shall be issued to
participants thereunder on the next currently scheduled purchase dates
thereunder occurring after the date hereof as provided under, and subject to the

<PAGE>

terms and conditions of, the Company ESPP. The Company may, consistent with past
practice, commence a new offering period under the Company ESPP on or after
February 1, 1999 and prior to the Effective Time at an exercise price for such
offering not less than as is required under the Company ESPP. Immediately prior
to the Effective Time, pursuant to Section 12(b) of the Company ESPP, all
offerings under the Company ESPP shall be terminated, and each participant shall
be deemed to have purchased immediately prior to the Effective Time, to the
extent of payroll deductions accumulated by such participant as of such offering
period end, the number of whole shares of Company Common Stock at a per share
price determined pursuant to the provisions of the Company ESPP, and each
participant shall receive a cash payment equal to the balance, if any, of such
accumulated payroll deductions remaining after such purchase of such shares. As
of the Effective Time, each participant shall receive, by virtue of the Merger,
the number of whole shares of Parent Common Stock into which the shares of
Company Common Stock such participant has so purchased under the Company ESPP
have been converted pursuant to the Merger as provided in Section 1.3(a) hereof,
plus the cash value of any fraction of a share of Parent Common Stock as
provided in Section 1.5(f) hereof, plus any dividends or distributions as
provided in Section 1.5(c). The Company ESPP and all purchase rights thereunder
shall terminate effective as of the Effective Time.

         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 or exchanged for a different number of shares or a different
class by reason of any reorganization, reclassification, subdivision,
recapitalization, split-up, combination, exchange of shares, stock dividend or
other similar transaction, the Conversion Ratio and all per-share price amounts
and calculations set forth in this Agreement shall be appropriately adjusted to
reflect such reorganization, reclassification, subdivision, recapitalization,
split-up, combination, exchange of shares, stock dividend or other similar
transaction.

         1.9 Certificate of Incorporation of the Surviving Corporation. The
Certificate of Incorporation of the Company, as in effect immediately prior to
the Effective Time, shall be amended to read as set forth on EXHIBIT A to this
Agreement.

         1.10 Bylaws of the Surviving Corporation. The Bylaws of Merger
Subsidiary, as in effect immediately prior to the Effective Time, shall, subject
to Section 5.15, 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 Merger 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.

                                    ARTICLE 2

                                     CLOSING

         2.1 Time and Place. Subject to the satisfaction or waiver of the
provisions of Article 6, the closing of the Merger (the "Closing") shall take
place at 1:00 p.m., local time, on the date that the Required Company

<PAGE>

Stockholder Vote (as defined in Section 3.2) is obtained, or as soon thereafter
as, and in any event no later than the second business day after, all conditions
to Closing have been satisfied or waived, or on such other date and/or at such
other time as Parent and the Company may mutually agree. The date on which the
Closing actually occurs is herein referred to as the "Closing Date." The Closing
shall take place at the corporate headquarters offices of Parent, or at such
other place or in such other manner (e.g., by telecopy exchange of signature
pages with originals to follow by overnight delivery) as the parties hereto may
agree.

         2.2 Filings at the Closing. At the Closing, subject to the provisions
of Article 6, Parent, Merger Subsidiary, and the Company shall cause the
Certificate of Merger to be filed in accordance with the provisions of Section
252 of the DGCL, and take any and all other lawful actions and do any and all
other lawful things necessary to cause the Merger to become effective.

                                    ARTICLE 3

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         Except: (i) as set forth in a document of even date herewith and
concurrently delivered herewith (the "Company Disclosure Schedule"); (ii) as
specifically described through express disclosure of current, specific facts set
forth in the Company's Annual Report on Form 10-K for the fiscal year ended June
30, 1998 or in any other filing by the Company with the SEC (as defined in
Section 3.4) filed after the date of filing such Form 10-K and prior to the date
hereof and the Company's Registration Statement on Form S-4 with respect to the
acquisition of World Medical (as defined below) as amended or supplemented prior
to the date hereof and previously delivered to Parent; (iii) as specifically
described in the schedules referred to in Section 3.1 of the Stock and Asset
Purchase Agreement dated July 9, 1998 between C. R. Bard, Inc. and the Company
(the "Bard Schedules"), as amended or supplemented prior to the date hereof and
previously delivered to Parent; or (iv) as specifically described in the
Disclosure Schedule delivered pursuant to Article 2 of the Agreement and Plan of
Merger and Reorganization dated April 10, 1998 between World Medical
Manufacturing Corporation ("World Medical"), Walleye Acquisition Corporation and
the Company (the "World Medical Schedules"), as amended or supplemented prior to
the date hereof and previously delivered to Parent (for purposes of clauses (i),
(ii), (iii) and (iv) above, disclosures in the Company Disclosure Schedule, such
Company SEC filings, the Bard Schedules or the World Medical Schedules shall be
deemed to qualify or limit only those particular representations and warranties
set forth in this Article 3 to which the relevancy of such disclosures is
readily apparent); the Company hereby makes the following representations and
warranties to Parent and Merger Subsidiary:

         3.1 Organization. The Company and each subsidiary of the Company
(referred to herein as a "Subsidiary") is an entity duly organized, validly
existing, and in good standing (where such concept is recognized) under the laws
of its respective jurisdiction of organization 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, except where the failure to be so
organized, existing or in good standing or to have such corporate power and
authority would not, individually or in the aggregate, have a Company Material
Adverse Effect (as defined below). The Company and each Subsidiary is duly
qualified and in good standing to do business in each jurisdiction in which the

<PAGE>

property owned, leased, or operated by it or the nature of the business
conducted by it makes such qualification necessary, except where the failure to
be so qualified or in good standing could not reasonably be expected to have a
Company Material Adverse Effect (as defined below). "Company Material Adverse
Effect" means an effect that, in the aggregate with other favorable and
unfavorable effects arising from breaches of the Company's representations and
warranties, is or would reasonably at the time of such effect be expected to be
materially adverse: (i) to the business, results of operation, or financial
condition of the Company and its Subsidiaries, considered as a whole; (ii) to
the ability of the Surviving Corporation to conduct such business, as presently
conducted, following the Effective Time or the ability of Parent to derive the
benefits of owning all of the stock of the Surviving Corporation; or (iii) to
the Company's ability to perform any of its material obligations under this
Agreement or to consummate the Merger, except in each case for any such effects
resulting from or arising out of (i) this Agreement or the transactions
contemplated by this Agreement or the announcement or pendency of the Merger,
(ii) any occurrence or condition affecting the medical device or stent
industries generally, or (iii) any changes in general economic, regulatory or
political conditions, and provided, that the probability of the Company being
indemnified by C.R. Bard, Inc. against such effects or related losses or
expenses (assuming a claim therefor is asserted as soon as reasonably
practicable) shall be taken into account for purposes of determining whether
there has been a Company Material Adverse Effect. The jurisdictions in which the
Company and each Subsidiary are incorporated are listed in the Company
Disclosure Schedule. The Company has heretofore delivered or made available to
Parent or its advisers complete and accurate copies of the Certificate of
Incorporation and Bylaws of the Company, as currently in effect, and of the
organizational documents and agreements defining the rights of the Company or
any Subsidiary with respect to any material joint ventures, partnerships or
other business in which the Company owns less than substantially all of the
outstanding equity interest. As of the date hereof, neither the Company nor any
Subsidiary, directly or indirectly, owns or controls or has any material equity,
partnership, or other similar ownership interest in any corporation,
partnership, joint venture, or other business association or entity that is
material to the Company and its Subsidiaries, considered as a whole.

         3.2 Authorization. The Company has all necessary corporate power and
authority to execute and deliver this Agreement and, subject to obtaining the
necessary approval of its stockholders, to consummate the transactions
contemplated hereby. The execution and delivery by the Company of this Agreement
and the other agreements contemplated hereby to which the Company is a party,
and the consummation by the Company of the transactions contemplated hereby and
thereby, have been duly and validly authorized and approved by the Company's
Board of Directors, no other corporate proceedings on the part of the Company
are necessary to authorize this Agreement, and, subject to obtaining the
approval and adoption of this Agreement and approval of the Merger by a majority
of the shares of the Company Common Stock outstanding as of the record date of
the Company's stockholder meeting (the "Required Company Stockholder Vote"), no
other corporate action on the part of the Company is necessary to consummate the
transactions contemplated hereby. The Merger has been declared advisable by the
Board of Directors of the Company. This Agreement has been duly and validly
executed and delivered by the Company and, assuming due execution and delivery
by the other parties hereto, constitutes the valid and binding obligation of the
Company, enforceable against the Company in accordance with its terms, subject

<PAGE>

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. As of the close of business on November 25, 1998,
the authorized capital stock of the Company consisted of (i) 300,000,000 shares
of Company Common Stock, $.001 par value per share, of which 64,360,781 were
issued and outstanding and 60,000 shares were held in the Company's treasury,
and (ii) 5,000,000 shares of Company Preferred Stock, $.001 par value per share,
of which 1,000,000 have been designated as Series A Preferred Stock and none of
which were issued or outstanding. 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 mortgage, pledge, security interest, encumbrance, lien or
other charge of any kind ("Lien") that would materially affect the Company's
interest in such shares. 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 (i) Company Options to purchase an aggregate of 346,332
shares of Company Common Stock not granted pursuant to any Company Stock Option
Plan (as defined below) and that are listed, together with their respective
exercise prices, in the Company Disclosure Schedule, (ii) Company Options to
purchase an aggregate of 3,901,835 shares of Company Common Stock that were
granted pursuant to the Company's 1996 Equity Incentive Plan and the Company's
1996 Non-Employee Directors' Stock Option Plan (collectively, the "Company Stock
Option Plans") and that are listed, together with their respective exercise
prices, in the Company Disclosure Schedule, (iii) the rights to purchase shares
of Company Common Stock under the Company ESPP (estimated to be approximately
250,000 shares as of the next purchase date under the Company ESPP, based on the
current contribution rates of the participants for the current Company ESPP
offerings in process as of the date of this Agreement) and (iv) the rights
outstanding pursuant to the Company Rights Agreement (as defined in Section
3.19), as of November 25, 1998, there were 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 was a party that, directly or
indirectly, (A) obligated 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, (B)
called for or related to the sale, pledge, transfer, or other disposition or
encumbrance by the Company or any Subsidiary of any shares of its capital stock,
or (C) to the knowledge of the Company, related to the voting or control of such
capital stock. The Company Disclosure Schedule sets forth a complete and
accurate list of all stock options, warrants, and other rights to acquire
Company Common Stock that were outstanding as of November 25, 1998, including
the name of the holder, the date of grant, acquisition price, number of shares,
exercisability schedule, and, in the case of options, the type of option under
the Code. No consent of holders or participants under the Company Stock Option
Plans or the Company ESPP is required to carry out the provisions of Section
1.7. All actions, if any, required on the part of the Company under the Company
Stock Option Plans or the Company ESPP to allow for the treatment of Company
Options and the Company ESPP as is provided in Section 1.7, have been, or prior
to the Closing will be, validly taken by the Company. In no event will the
aggregate number of shares of Company Common Stock outstanding at the Effective
Time (including all shares subject to then outstanding Company Options or other

<PAGE>

rights to acquire or commitments to issue shares of Company stock, other than
the Stock Option Agreement referenced in Section 5.13) exceed the sum of (w) the
outstanding shares of Company Common Stock described in the first sentence of
this Section 3.3, plus (x) any shares of Company Common Stock issued upon the
exercise of outstanding options to purchase Company Common Stock identified in
Section 3.3, plus (y) any shares of Company Common Stock issued by the Company
upon the exercise of rights under the Company ESPP, plus (z) any additional
shares identified in Section 3.3 of the Company Disclosure Schedule or permitted
to be issued under Section 5.1(b) hereof.

         3.4 Reports and Financial Statements. The Company has filed all forms,
reports, registration statements, and other 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 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
included or incorporated by reference in the Company SEC Filings, including but
not limited to the Company's audited financial statements at and for the year
ended June 30, 1998 (the "Company June 30, 1998 Financials"), and the unaudited
interim financial statements at and for periods commencing on or after July 1,
1998, included or incorporated by reference in the forms, reports, registration
statements and other documents filed by the Company with the SEC (i) were
prepared in accordance with generally accepted accounting principles (except, in
the case of unaudited statements, as permitted by Form 10-Q filed with the SEC)
applied on a consistent basis during the periods involved (except as may be
indicated therein or in the notes thereto), subject, in the case of unaudited
interim financial statements, to the absence of notes and to year-end
adjustments, (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 financial position of the Company and its consolidated
subsidiaries as of the dates thereof and the consolidated income, cash flows,
and changes in stockholders' equity of the Company and its consolidated
subsidiaries for the periods involved, except as otherwise noted therein and
subject, in the case of unaudited statements, to normal year-end audit
adjustments. The statements of operations included in the audited or unaudited
interim financial statements in the Company SEC Filings do not contain any items
of special or nonrecurring income or any other income not earned in the ordinary
course of business required to be disclosed separately in accordance with
generally accepted accounting principles, except as expressly specified in the
applicable statement of operations or notes thereto.

         3.5 Absence of Undisclosed Liabilities. To the best of the Company's
knowledge, neither the Company nor any Subsidiary has any liabilities or
obligations of any nature (whether absolute, accrued, contingent or otherwise)
of the type required to be reflected on or reserved against in, or disclosed in
the notes to, a balance sheet prepared in accordance with U.S. generally

<PAGE>

accepted accounting principles except: (a) liabilities or obligations that are
accrued or reserved against in the audited consolidated balance sheet of the
Company and its consolidated subsidiaries as of June 30, 1998 contained in the
Company June 30, 1998 Financials (the "Company Audited Balance Sheet") or in the
unaudited consolidated balance sheet of the Company and its consolidated
subsidiaries as of September 30, 1998 contained in the Company's Quarterly
Report on Form 10-Q for the fiscal quarter ended September 30, 1998 (the
"Company Interim Balance Sheet") or referred to in the notes thereto, (b)
liabilities incurred in the ordinary course of business since September 30, 1998
and (c) liabilities or obligations that could not reasonably be expected to 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) obtaining the Required Company Stockholder Vote and
any stockholder vote necessary under the requirements of Nasdaq with respect to
issuance of shares of Company Common Stock pursuant to the Stock Option
Agreement described in Section 5.13, (iii) the filing and recordation of
appropriate merger documents as required by the DGCL, the execution and delivery
by the Company of this Agreement and the other agreements contemplated hereby to
which the Company is a party and the consummation by the Company of the
transactions contemplated hereby and thereby will not: (a) violate any provision
of the Certificate or Articles of Incorporation or Bylaws of the Company or any
Subsidiary; (b) violate any material statute, rule, regulation, order, or decree
of any federal, state, local, or foreign governmental or regulatory body or
authority (including, but not limited to, the Food and Drug Administration (the
"FDA")) (a "Governmental Body") 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 by the Company with or permit,
consent, or approval to be obtained by the Company from any Governmental Body 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 3.3) 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 clauses (c)
and (d), for any such filings, permits, consents or approvals or violations,
breaches, defaults, or other occurrences that could not reasonably be expected
to 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 could not
reasonably be expected to have a Company Material Adverse Effect. Section 3.6 of
the Company Disclosure Schedule lists each 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 and which is material to the

<PAGE>

Company and its Subsidiaries, considered as a whole, under or with respect to
which the transactions contemplated by this Agreement will result in any
material violation or breach of, or constitute (with or without due notice or
lapse of time or both) a material default under, result in the loss of any
material benefit under, or give rise to any material right of termination,
cancellation, increased payments, or acceleration under, or result in the
creation of any material Lien on any of the material properties or assets of the
Company or any Subsidiary.

         3.7 Compliance with Laws. Neither the Company nor any Subsidiary is in
default or violation of any applicable federal, state, local, or foreign laws,
ordinances, regulations, interpretations, judgments, decrees, injunctions,
permits, licenses, certificates, governmental requirements, orders, or other
similar items of any court or other Governmental Body (and including those of
any nongovernmental self-regulatory agency and including environmental laws or
regulations), except for such defaults or violations that could not reasonably
be expected to have a Company Material Adverse Effect. The Company and each
Subsidiary have 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 Governmental Body with jurisdiction over the
manufacture, use, or sale of the Regulated Products, and all regulatory licenses
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 could not reasonably be expected to have a Company Material Adverse
Effect.

         3.8  Litigation.

                  (a) As of the date of this Agreement, there is no
Merger-Related Proceeding pending, or to the knowledge of the Company,
threatened in writing against the Company. (For purposes of this Agreement,
"Merger-Related Proceeding" shall mean any meritorious asserted claim, action,
suit, proceeding, or to the Company's knowledge, governmental investigation or
governmental review of any kind: (i) challenging or seeking to prevent, enjoin
or delay the Merger or any of the other transactions contemplated by this
Agreement, or (ii) seeking material damages from the Company or any of its
Subsidiaries or from Parent or any of its subsidiaries in connection with the
consummation or anticipated consummation of the Merger.)

                  (b) There are no meritorious asserted claims, actions, suits,
proceedings or, to the knowledge of the Company, governmental investigations or
governmental reviews of any kind pending, or to the knowledge of the Company,
threatened in writing against the Company or any Subsidiary or any asset or
property of the Company or any Subsidiary, other than Merger-Related Proceedings
and except for such claims, actions, suits, proceedings, governmental
investigations or governmental reviews that could not reasonably be expected to
have a Company Material Adverse Effect.

         3.9 Absence of Material Adverse Changes. Between June 30, 1998 and the
date hereof, there has not been any (a) Company Material Adverse Effect; (b)
damage, destruction, or loss, not covered by insurance, that could reasonably be

<PAGE>

expected to have a Company Material Adverse Effect; (c) material change by the
Company or any Subsidiary in accounting methods or principles used for financial
reporting purposes, except as required by a change in applicable law or
generally accepted accounting principles and concurred with by the Company's
independent public accountants; or (d) agreement, whether in writing or
otherwise, to take any action described or referenced in this Section 3.9. To
the knowledge of the Company, between June 30, 1998 and the date of this
Agreement, there have been no events, occurrences or developments with respect
to the business or assets of World Medical that could, assuming the Company's
acquisition of World Medical, reasonably be expected to have a Company Material
Adverse Effect.

         3.10 Officers, Directors and Employees. Prior to the date hereof, the
Company has provided to Parent a list that completely and accurately sets forth,
as of the date hereof, the name and current annual salary rate of each current
officer of the Company whose total remuneration for the last fiscal year was, or
for the current fiscal year has been set at, in excess of $150,000, together
with a summary of the bonuses, commissions, additional compensation, and other
like cash benefits, if any, paid or payable to such persons for the last fiscal
year and proposed for the current fiscal year. The Company Disclosure Schedule
completely and accurately sets forth (i) the names of all former officers of the
Company whose employment with the Company has terminated either voluntarily or
involuntarily during the 12-month period preceding the date of this Agreement;
and (ii) the names of the officers (with all positions and titles indicated) and
directors of the Company as of the date hereof. Except as could not reasonably
be expected to have a Company Material Adverse Effect: (i) no unfair labor
practice complaint against the Company or any Subsidiary is pending before the
National Labor Relations Board, and there is no labor strike, slowdown or
stoppage pending or, to the knowledge of the Company, threatened in writing
against or involving the Company or any Subsidiary; (ii) no unionizing efforts
have, to the knowledge of the Company, been made by employees of the Company or
any Subsidiary, (iii) neither the Company nor any Subsidiary is a party to or
subject to any collective bargaining agreement, and no collective bargaining
agreement is currently being negotiated by the Company or any Subsidiary; and
(iv) there is no labor dispute pending or, to the knowledge of the Company,
threatened in writing, between the Company or any Subsidiary and its employees.

         3.11 Taxes. Except for such matters that would not have a Company
Material Adverse Effect, (i) the Company and each Subsidiary have filed, or have
obtained extensions to file (which extensions have not expired without filing),
all state, local, United States, foreign, or other tax reports and returns
required to be filed by any of them, (ii) the Company and each Subsidiary have
duly paid, or accrued on their books of account, all taxes (including estimated
taxes) shown as due on such reports and returns (or such extension requests), or
assessed against them, other than taxes being contested in good faith in proper
proceedings, and (iii) to the Company's knowledge, the liabilities and reserves
for taxes reflected on the Company Audited Balance Sheet or the Company Interim
Balance Sheet are adequate to cover all taxes payable by the Company and its
Subsidiaries for all taxable periods and portions thereof ending on or before
the dates thereof. To the Company's knowledge, no tax audits are pending against
and no claims for taxes have been received in writing by the Company or any of
its Subsidiaries, other than audits and claims that are not reasonably expected

<PAGE>

to have a Company Material Adverse Effect. 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. Neither the Company nor, to the knowledge of the Company, any of
its Subsidiaries has taken or agreed to take any action (other than actions
contemplated by this Agreement) that would prevent the Merger from constituting
a reorganization qualifying under Section 368(a) of the Code. The Company is not
aware of any agreement, plan or other circumstance that would prevent the Merger
from so qualifying under Section 368(a) of the Code.

         For the purposes of this Agreement, "tax" shall mean and include taxes,
duties, withholdings, assessments, and charges assessed or imposed by any
governmental authority (together with any interest, penalties and additions to
tax imposed with respect thereto), including but not limited to all federal,
state, county, local, and foreign income, profits, gross receipts, import, ad
valorem, real and personal property, franchise, license, sales, use, value
added, stamp, transfer, withholding, payroll, employment, excise, custom, duty,
and any other taxes, obligations and assessments of any kind whatsoever; "tax"
shall also include any liability for taxes arising as a result of being (or
ceasing to be) a member of any affiliated, consolidated, combined, or unitary
group as well as any liability for taxes under any tax allocation, tax sharing,
tax indemnity, or similar agreement.

         3.12 Contracts. The Company Disclosure Schedule lists, and the Company
has heretofore furnished to Parent complete and accurate copies of (or, if oral,
the Company Disclosure Schedule states all material provisions of), (a) every
employment, material consulting, severance or change of control agreement or
arrangement for the benefit of any director, officer, employee, other person or
stockholder of the Company or any Subsidiary or any affiliate thereof in effect
as of the date of this Agreement to which the Company or any Subsidiary is a
party or by which the Company or any Subsidiary or any of their properties or
assets is bound, and (b) every contract with physicians, scientific advisory
board members or material consultants in effect as of the date of this Agreement
to which the Company or any Subsidiary is a party or by which the Company or any
Subsidiary or any of their properties or assets is bound. Neither the Company
nor any Subsidiary is in material violation of or in default under any contract,
plan, agreement, understanding, arrangement or obligation that is material to
the Company and its Subsidiaries considered as a whole, except for such
violations or defaults that could not reasonably be expected to have a Company
Material Adverse Effect. As of the date of this Agreement, neither the Company
nor any Subsidiary is a party to any contract, plan, agreement, understanding,
arrangement or obligation (i) which materially restricts the Company's, or after
the Merger would materially restrict the Surviving Corporation's or Parent's,
ability to conduct any material line of business, (ii) which imposes on the
Company or any Subsidiary material obligations (including, without limitation,
to pay material milestone payments or material license fees) not reflected in
the Company's financial statements included within the Company's SEC Filings, or
(iii) that 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 is applicable, which has not been so filed. To the Company's knowledge,
as of the date hereof, World Medical is not a party to any contract, plan,
agreement, understanding, arrangement or obligation which materially restricts
World Medical's, or after the Merger would materially restrict the Surviving
Corporation's or Parent's, ability to conduct any material line of business.


<PAGE>

         3.13 Intellectual Property Rights. For purposes of this Section,
"Intellectual Property" shall mean patents, registered trademarks, registered
trade names, registered service marks, registered copyrights, and all
applications for or registrations of any of the foregoing. As of the date of
this Agreement, the Company Disclosure Schedule contains a complete and accurate
list of all material Intellectual Property owned by or licensed exclusively or
(with respect to patents material to the products or operations of the Company
which would be infringed by the Company, any Subsidiary or their products but
for such license) non-exclusively to the Company or any Subsidiary (the "Company
Intellectual Property"). The Company Intellectual Property is owned by or
licensed to the Company or a Subsidiary free and clear of any Lien (as defined
in Section 3.3) that would materially adversely affect the Company's rights
thereunder. No claim is being asserted and, to the knowledge of the Company, no
person is threatening in a writing delivered to the Company to assert a claim,
with respect to the use of the Company Intellectual Property owned by the
Company or challenging or questioning the validity or effectiveness of any
license or agreement with respect to any Company Intellectual Property, except
for such claims that could not reasonably be expected to have a Company Material
Adverse Effect. To the knowledge of the Company, neither the use by the Company
or any Subsidiary of the Company Intellectual Property in the present conduct of
its business nor any product or service of the Company or any Subsidiary
infringes on the valid intellectual property rights of any person in a manner
that could reasonably be expected to have a Company Material Adverse Effect.
Except as could not reasonably be expected to have a Company Material Adverse
Effect, (i) all Company Intellectual Property listed in the Company Disclosure
Schedule that is owned by the Company has the status indicated therein and,
unless provided otherwise, all applications are still pending in good standing
and have not been abandoned, and (ii) to the knowledge of the Company, the
Company Intellectual Property is valid and is not being challenged in any
judicial or administrative (excluding any patent-office or registration)
proceeding. To the knowledge of the Company, no person or entity nor such
person's or entity's business or products has infringed, or misappropriated any
Company Intellectual Property, or currently is infringing, or misappropriating
any Company Intellectual Property, except as could not reasonably be expected to
have a Company Material Adverse Effect.

         3.14 Benefit Plans.

                  (a) Neither the Company nor any Subsidiary sponsors,
maintains, contributes to, or has, during the five year period ending on the
date of this Agreement, sponsored, maintained, or contributed to or been
required to contribute to, any "employee pension benefit plan" ("Pension Plan"),
as such term is defined in Section 3(2) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), including, solely for the purpose of
this subsection, a plan excluded from coverage by Section 4(b)(5) of ERISA. Each
such Pension Plan presently maintained by the Company or any Subsidiary is, in
all material respects, in compliance with applicable provisions of ERISA, the
Code, and other applicable law and the Company or such Subsidiary has performed
all of its obligations under such Pension Plan except for such obligations that
could not reasonably be expected to have a Company Material Adverse Effect.


<PAGE>

                  (b) Neither the Company nor any Subsidiary sponsors,
maintains, contributes to, or has, during the five year period ending on the
date of this Agreement, sponsored, maintained, or contributed to or been
required to contribute to, any Pension Plan that is subject to Title IV of
ERISA.

                  (c) Neither the Company nor any Subsidiary sponsors,
maintains, or contributes 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,
Section 4980B of the Code and the regulations thereunder, and Part 6 of Title I
of ERISA. 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 Code.

                  (d) Neither the Company nor any Subsidiary currently maintains
or contributes to any oral or written bonus, profit-sharing, compensation
(incentive or otherwise), commission, stock option, or other stock-based
compensation, retirement, severance, change of control, vacation, sick or
parental leave, dependent care, deferred compensation, cafeteria, disability,
hospitalization, medical, death, retiree, insurance, or other benefit or welfare
or other similar plan, policy, agreement, trust, fund, or arrangement providing
for the remuneration or benefit of all or any employees, directors or any other
person, that is neither a Pension Plan nor a Welfare Plan (collectively, the
"Compensation Plans").

                  (e) With respect to the Pension Plans, Welfare Plans or
Compensation Plans, no event has occurred and, to the knowledge of the Company,
there exists no condition or set of circumstances, in connection with which the
Company or any of its Subsidiaries could be subject to any liability under the
terms of such Plans (other than the payment of benefits thereunder), ERISA, the
Code or any other applicable law which could reasonably be expected to have a
Company Material Adverse Effect.

                  (f) The Internal Revenue Service has issued favorable
determination letters with respect to all Company and Subsidiary Pension Plans
that are intended to be qualified under Section 401(a) of the Code. The Company
has provided to Parent the written documents setting forth the terms of all
Pension Plans, Welfare Plans, Compensation Plans, and related agreements, and
complete and accurate copies of all annual reports (Form 5500), favorable
determination letters, current summary plan descriptions, and all employee
handbooks or manuals. The Company has provided to Parent (i) copies of all
employment agreements with officers of any of the Company, its U.S. Subsidiaries
or, to the extent reasonably available, the Company's non-U.S. Subsidiaries (or
copies of forms of agreements setting forth representative employment terms and
conditions); (ii) copies of all severance, bonus or incentive agreements,
programs and policies of any of the Company, any U.S. Subsidiary or, to the
extent reasonably available, the Company's non-U.S. Subsidiaries with or
relating to any of its employees; and (iii) copies of all plans, programs,
agreements and other arrangements of any of the Company, any U.S. Subsidiary or,
to the extent reasonably available, the Company's non-U.S. Subsidiaries with or
relating to any of its employees which contain change in control provisions.

<PAGE>

With respect to any items that would be described in the immediately preceding
sentence but for the fact that such copies relate to non-U.S. Subsidiaries and
are not reasonably available to the Company, the Company (i) shall deliver
copies thereof to Parent prior to the Effective Time, and (ii) represents and
warrants to Parent that such items will not, individually or in the aggregate,
be material to the Company and its Subsidiaries.

                  (g) The execution by the Company of, and performance by the
Company 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 result in any payment (whether of severance pay or
otherwise), acceleration, forgiveness of indebtedness, vesting, distribution,
increase in benefits, or obligation to fund benefits. 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 Prop. Treas. Reg. 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).

         3.15 Minute Books. The Company has previously made available to Parent
or its representatives all of its minutes of meetings of and corporate actions
or written consents by the stockholders, Board of Directors, and committees of
the Board of Directors of the Company.

         3.16 No Finders. No act of the Company or any Subsidiary has given or
will give rise to any claim against any of the parties hereto for a brokerage
commission, finder's fee, or other like payment in connection with the
transactions contemplated herein, except payments in the amounts specified in
the Company Disclosure Schedule to those parties identified thereon who have
acted as a finder for the Company or have been retained by the Company as
financial advisors pursuant to the agreements or other documents described in
the Company Disclosure Schedule, copies of which have been provided or made
available to Parent or its advisors prior to the date of this Agreement.

         3.17 Proxy Statement. The Proxy Statement/Prospectus (as defined in
Section 5.5 hereof) and any amendments or supplements thereto will comply as to
form in all material respects with all applicable laws, and none of the
information supplied by the Company specifically for inclusion or incorporation
therein or in any amendments or supplements thereto, or in any schedules
required to be filed with the SEC in connection therewith, will, at the date the
Proxy Statement/Prospectus (or any amendment or supplement thereto) is first
mailed to stockholders, or at the time of the Company Stockholders' Meeting,
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 the
Company with respect to information relating to Parent or any affiliate of
Parent supplied by Parent specifically for inclusion in the Proxy
Statement/Prospectus.

Cowen Securities Corporation to the effect that, as of the date of such opinion,
the Conversion Ratio is fair, from a financial point of view, to the holders of
Company Common Stock, and the Company will promptly deliver a copy of such

         3.19 State Takeover Laws; Rights Plan.

                  (a) The Board of Directors of the Company has approved the
transactions contemplated by this Agreement, such that the provisions of Section
203 (entitled "Business Combinations with Interested Shareholders") of the DGCL

thereby.

                  (b) The Company has taken all actions and completed all
amendments, if any, necessary or appropriate so that (i) the Rights Agreement
dated as of February 26, 1997, as amended, between the Company and BankBoston,
N.A. (the "Company Rights Agreement"), is inapplicable to the transactions
contemplated by the Agreements to Facilitate Merger, the Stock Option Agreement
and this Agreement, (ii) the execution of this Agreement, the Stock Option
Agreement, and the Agreements to Facilitate Merger, and the consummation of the
transactions contemplated hereby and thereby, do not and will not (w) result in
Parent being an "Acquiring Person" (as such term is defined in the Company
Rights Agreement), (x) result in the ability of any person to exercise any
Rights under the Company Rights Agreement, (y) enable or require the Rights to
separate from the shares of Company Common Stock to which they are attached or
to be triggered or become exercisable, or (z) otherwise result in the occurrence
of a "Distribution Date" or "Shares Acquisition Date" (as such terms are defined
in the Company Rights Agreement), and (iii) immediately prior to the Effective
Time, the Rights under the Company Rights Agreement shall, without any payment
by the Company or Parent, expire with neither the Company nor Parent having any
obligations under, and no holder of Rights having any rights under, the Company
Rights Agreement.

                                    ARTICLE 4

                         REPRESENTATIONS AND WARRANTIES
                         OF PARENT AND MERGER SUBSIDIARY

         Except (i) as set forth in a document of even date herewith and
concurrently delivered herewith (the "Parent Disclosure Schedule") or (ii) as
specifically described through express disclosure of current, specific facts set
forth in Parent's Annual Report on Form 10-K for the fiscal year ended April 30,
1998 or in any other filing by Parent with the SEC filed after the date of

<PAGE>

filing such Form 10-K and prior to the date hereof (for purposes of clauses (i)
and (ii) above, disclosures in the Parent Disclosure Schedule and such Parent
SEC filings shall be deemed to qualify or limit only those particular
representations and warranties set forth in this Article 4 to which the
relevancy of such disclosures is readily apparent), Parent and Merger Subsidiary
hereby jointly and severally make the following representations and warranties
to the Company:

         4.1 Organization. Parent is a corporation duly organized, validly
existing, and in good standing under the laws of the State of Minnesota. Merger
Subsidiary is a corporation duly organized and validly existing under the laws
of the State of Delaware. Each of Parent and Merger Subsidiary has all requisite
corporate power and authority to own, lease, and operate its properties and to
carry on its business as now being conducted, except where the failure to be so
organized, existing or in good standing or to have such corporate power and
authority would not, individually or in the aggregate, have a Parent Material
Adverse Effect (as defined below). Each of Parent and Merger 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, except where the failure to
be so qualified or in good standing could not reasonably be expected to have a
Parent Material Adverse Effect (as defined below). "Parent Material Adverse
Effect" means an effect that, in the aggregate with other favorable and
unfavorable effects arising from breaches of Parent's and Merger Subsidiary's
representations and warranties, is or would reasonably at the time of such
effect be expected to be materially adverse: (i) to the business, results of
operation, or financial condition of Parent and its subsidiaries, considered as
a whole, or (ii) to Parent's ability to perform any of its material obligations
under this Agreement or to consummate the Merger, except in each case for any
such effects resulting from or arising out of (i) this Agreement or the
transactions contemplated by this Agreement or the announcement or pendency of
the Merger, (ii) any occurrence or condition affecting the medical device
industry generally or affecting Parent's principal market sector generally, or
(iii) any changes in general economic, regulatory or political conditions.
Parent has heretofore delivered or made available to the Company or its advisors
complete and accurate copies of the Articles of Incorporation and Bylaws of
Parent, as currently in effect.

         4.2 Authorization. Each of Parent and Merger Subsidiary has all
necessary corporate power and authority to execute and deliver this Agreement
and to consummate the transactions contemplated hereby. The execution and
delivery by Parent and Merger Subsidiary of this Agreement and the other
agreements contemplated hereby to which Parent or Merger Subsidiary is a party,
and the consummation by Parent and Merger Subsidiary of the transactions
contemplated hereby and thereby, have been duly and validly authorized and
approved by the Boards of Directors of Parent and Merger Subsidiary and by
Parent as the sole shareholder of Merger Subsidiary, and no other corporate
proceedings on the part of Parent and Merger Subsidiary, and no vote, consent or
approval of Parent's shareholders, are necessary to authorize this Agreement or
to consummate the transactions contemplated hereby. The Merger has been declared
advisable by the Board of Directors of Merger Subsidiary. This Agreement has
been duly and validly executed and delivered by each of Parent and Merger
Subsidiary and, assuming due execution and delivery by the Company, constitutes
the valid and binding obligation of Parent and Merger Subsidiary, enforceable
against each of them in accordance with its terms, subject to laws of general

<PAGE>

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 October 23, 1998, 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 489,262,955 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
shares issued and outstanding. The authorized capital stock of Merger Subsidiary
consists of 2,500 shares of Merger Subsidiary Common Stock, 100 of which are
issued and outstanding and owned by Parent. All issued and outstanding shares of
Parent Common Stock and Merger 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 DGCL, the execution and delivery by Parent and
Merger Subsidiary of this Agreement and the other agreements contemplated hereby
to which Parent and Merger Subsidiary are parties, and the consummation of the
transactions contemplated hereby and thereby will not: (a) violate any provision
of the Certificate or Articles of Incorporation or Bylaws of Parent or Merger
Subsidiary; (b) violate any material statute, rule, regulation, order, or decree
of any Governmental Body or any nongovernmental self-regulatory agency by which

assets may be bound; (c) require any filing by Parent or Merger Subsidiary with
or permit, consent, or approval to be obtained by Parent or Merger Subsidiary

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 clauses (c) and (d), for any such filings, permits, consents or approvals or
violations, breaches, defaults, or other occurrences that could not reasonably
be expected to 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
could not reasonably be expected to have a Parent Material Adverse Effect.

         4.5 Reports; Financial Statements; Absence of Changes. Parent has filed
all forms, reports, registration statements, and other documents required to be
filed by it with the SEC since May 1, 1995 (such forms, reports, registration
statements and other documents, together with any amendments thereto, are

<PAGE>

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 included or incorporated
by reference in the Parent SEC Filings, including but not limited to Parent's
audited financial statements at and for the year ended April 30, 1998 (the
"Parent April 30, 1998 Financials"), and the unaudited interim financial
statements at and for periods commencing on or after May 1, 1998 included or
incorporated by reference in the forms, reports, registration statements and
other documents filed by Parent with the SEC (i) were prepared in accordance
with generally accepted accounting principles (except, in the case of unaudited
statements, as permitted by Form 10-Q filed with the SEC) applied on a
consistent basis during the periods involved (except as may be indicated therein
or in the notes thereto) subject, in the case of unaudited interim financial
statements, to the absence of notes and to year-end adjustments, (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
financial position of Parent and its consolidated subsidiaries as of the dates
thereof and the consolidated income, cash flows, and changes in shareholders'
equity of Parent and its consolidated subsidiaries for the periods involved,
except as otherwise noted therein and subject, in the case of unaudited
statements, to normal year-end audit adjustments. The statements of operations
included in the audited or unaudited interim financial statements in the Parent
SEC Filings do not contain any items of special or nonrecurring income or any
other income not earned in the ordinary course of business required to be
disclosed separately in accordance with generally accepted accounting
principles, except as expressly specified in the applicable statement of
operations or notes thereto.

         4.6 Registration Statement. The Registration Statement (as defined in
Section 5.5 hereof) and any amendments or supplements thereto will comply as to
form in all material respects with the 1933 Act, and none of the information
supplied by Parent specifically for inclusion or incorporation therein or in any
amendments or supplements thereto, or in any schedules required to be filed with
the SEC in connection therewith, will, at the time the Registration Statement
becomes effective, at the date the Proxy Statement/Prospectus (or any amendment
or supplement thereto) is first mailed to stockholders, or at the time of the
Company Stockholders' Meeting, 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.

         4.7 No Finders. No act of Parent or Merger Subsidiary has given or will
give rise to any claim against any of the parties hereto for a brokerage
commission, finder's fee, or other like payment in connection with the
transactions contemplated herein, except for payments to Goldman Sachs & Co. for
financial advisory services to Parent in connection herewith.


<PAGE>

         4.8 Absence of Undisclosed Liabilities. To the best of Parent's
knowledge, neither Parent nor any of its subsidiaries has any liabilities or
obligations of any nature (whether absolute, accrued, contingent or otherwise)
of the type required to be reflected on or reserved against in, or disclosed in
the notes to, a balance sheet prepared in accordance with U.S. generally
accepted accounting principles except: (a) liabilities or obligations that are
accrued or reserved against in the audited consolidated balance of Parent as of
April 30, 1998 contained in the Parent SEC Filings or in the unaudited
consolidated balance sheet of Parent as of July 31, 1998 contained in Parent's
Quarterly Report on Form 10-Q for the fiscal quarter ended July 31, 1998 or
referred to in the notes thereto, (b) liabilities incurred in the ordinary
course of business since July 31, 1998 and (c) liabilities or obligations that
could not reasonably be expected to have a Parent Material Adverse Effect.

         4.9 Compliance with Laws. Neither Parent nor any of its subsidiaries is
in default or violation of any applicable federal, state, local or foreign laws,
ordinances, regulations, interpretations, judgments, decrees, injunctions,
permits, licenses, certificates, governmental requirements, orders or other
similar items of any court or other Governmental Body (and including those of
any nongovernmental self-regulatory agency and including environmental laws or
regulations), except for such defaults or violations that could not reasonably
be expected to have a Parent Material Adverse Effect. Parent and each of its
subsidiaries has timely filed or otherwise provided all registrations, reports,
data and other information and applications with respect to its Regulated
Products required to be filed with or otherwise provided to the FDA or any other
Governmental Body with jurisdiction over the manufacture, use of sale of the
Regulated Products, and all regulatory licenses 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 could not reasonably
be expected to have a Parent Material Adverse Effect.

         4.10 Litigation.

                  (a) As of the date of this Agreement, there is no
Merger-Related Proceeding pending, or to the knowledge of Parent, threatened in
writing against Parent.

                  (b) There are no meritorious asserted claims, actions, suits,
proceedings or to the knowledge of Parent, governmental investigations or
governmental reviews of any kind pending, or to the knowledge of Parent,
threatened in writing against Parent or any of its subsidiaries or any asset or
property of Parent or any of its subsidiaries, other than Merger-Related
Proceedings and except for such claims, actions, suits, proceedings,
governmental investigations or governmental reviews that could not reasonably be
expected to have a Parent Material Adverse Effect.

         4.11 Absence of Material Adverse Changes. Between April 30, 1998 and
the date hereof, there has not been any (a) Parent Material Adverse Effect, (b)
damage, destruction or loss, not covered by insurance, that could reasonably be
expected to have a Parent Material Adverse Effect, (c) material change by Parent
or any of its subsidiaries in accounting methods or principles used for
financial reporting purposes, except as required by a change in applicable law

<PAGE>

or generally accepted accounting principles and concurred with by Parent's
independent public accountants, or (d) agreement, whether in writing or
otherwise, to take any action described or referenced in this Section 4.11. To
the knowledge of Parent, between April 30, 1998 and the date of this Agreement,
there have been no events, occurrences or developments with respect to the
business or assets of either AVECOR Cardiovascular Inc. or Sofamor Danek Group,
Inc. that could, assuming Parent's acquisition of either such entity, reasonably
be expected to have a Parent Material Adverse Effect.

         4.12 Reorganization. Neither Parent nor, to the knowledge of Parent,
any of its subsidiaries has taken or agreed to take any action (other than
actions contemplated by this Agreement) that would prevent the Merger from
constituting a reorganization qualifying under Section 368(a) of the Code.
Parent is not aware of any agreement, plan or other circumstances that would
prevent the Merger from so qualifying under Section 368(a) of the Code.

         4.13 Merger Filings. The information as to Parent and Merger Subsidiary
or any of their affiliates or shareholders included in Parent's filing, or
submitted to the Company for inclusion in its filing, if any, required to be
submitted under the HSR Act or under any Foreign Merger Laws shall be true,
correct, and complete in all material respects and shall comply in all material
respects with the applicable requirements of the HSR Act, the rules and
regulations issued by the Federal Trade Commission pursuant thereto, and Foreign
Merger Laws.

(f), (g), (i), (j), (k), (l), (m), (n), or (o) above; or

                  (q) agree, whether in writing or otherwise, to do any of the
foregoing.

         5.2 Conduct of Business of Parent. Except as contemplated by this
Agreement, from the date of this Agreement until the Effective Time, Parent will
not do, and will not permit any of its subsidiaries to do, any of the following
without the prior written consent of the Company (such consent not to be
unreasonably withheld or delayed):

                  (a) combine or reclassify any shares of its capital stock,
declare, set aside or pay any extraordinary dividend or other distribution
(whether in cash, stock or property or any combination thereof, but excluding a
stock split effected in the form of a stock dividend) in respect of its capital
stock, or redeem or otherwise acquire (other than pursuant to Parent's
previously established stock repurchase program or as would not violate Section
5.21) any shares of its capital stock or amend or alter any material term of any
of its outstanding securities;

                  (b) acquire or agree to acquire, by merging or consolidating
with, or by purchasing a substantial portion of the assets of, or by any other
manner, any business of any corporation, partnership, joint venture, association
or other business organization or division thereof, or otherwise acquire or
agree to acquire, or dispose of or agree to dispose of, any assets of any
person, which, in each case, could reasonably be expected to delay materially
the consummation of, or increase materially the risk of non-consummation of, the
transactions contemplated by this Agreement;

                  (c) alter or revise its accounting principles, procedures,
methods or practices in any material respect, except as required by applicable
law or regulation or by a change in generally accepted accounting principles and
concurred with by Parent's independent public accountants;


<PAGE>

                  (d) knowingly take any action that would result in a failure
to maintain the trading of Parent Common Stock on the NYSE;

                  (e) knowingly take any action, or knowingly fail to take any
action, that would render any representation, warranty, covenant or agreement of
Parent in this Agreement inaccurate or breached such that the conditions in
Section 6.3 will not be satisfied; or

                  (f) fail to use commercially reasonable efforts to cause
AVECOR Cardiovascular Inc. and Sofamor Danek Group, Inc. to refrain from taking
any actions described in subsection (e) above; or

                  (g) agree, whether in writing or otherwise, to do any of the
foregoing.

              5.3 No Solicitation. The Company and its Subsidiaries shall not,
and shall cause their respective officers, directors, employees,
representatives, agents, or affiliates (including, but not limited to any
investment banker, attorney, or accountant retained by the Company or any
Subsidiary), not to, directly or indirectly, solicit, knowingly encourage,
initiate, or participate in any way in discussions or negotiations with, or
knowingly provide any nonpublic information to, any corporation, partnership,
person, or other entity or group (other than Parent or any affiliate or agent of
Parent) concerning any proposed Alternative Transaction, or otherwise knowingly
facilitate any effort or attempt to make or implement an Alternative
Transaction. For purposes of this Agreement, "Alternative Transaction" shall
mean any of the following involving the Company or any Subsidiary: (i) any
tender offer, exchange offer, merger, consolidation, share exchange, business
combination or similar transaction; (ii) any transaction or series of related
transactions pursuant to which any person or entity (or its shareholders), other
than Parent, or Merger Subsidiary or any of their affiliates (a "Third Party")
acquires shares (or securities exercisable for or convertible into shares)
representing more than 20% of the outstanding shares of any class of capital
stock of the Company or any Subsidiary; or (iii) any sale, lease, exchange,
licensing, transfer or other disposition pursuant to which a Third Party
acquires control of more than 20% of the assets (including, but not limited to,
intellectual property assets) of the Company and its Subsidiaries taken as a
whole (determined by reference to the fair market value of such assets), in a
single transaction or series of related transactions; provided, however, that
the proposed transaction with World Medical shall not constitute an Alternative
Transaction. The Company will immediately terminate all discussions with Third
Parties concerning any proposed Alternative Transaction, and will request that
such Third Parties promptly return any confidential information furnished by the
Company in connection with any proposed Alternative Transaction. The Company
will not waive any provision of any confidentiality, standstill or similar
agreement entered into with any third party regarding any proposed Alternative
Transaction, and prior to the Closing shall enforce all such agreements in
accordance with their terms. The Company will promptly communicate to Parent the
name of the person or entity submitting, and the terms and conditions of, any
proposal or inquiry that it receives after the date hereof in respect of any
proposed Alternative Transaction or a reasonably detailed description of any

<PAGE>

such information requested from it after the date hereof or of any such
negotiations or discussions being sought to be initiated or continued with the
Company after the date hereof in respect of a proposed Alternative Transaction;
provided, however, that this Agreement shall not prohibit the Board of Directors
of the Company from (i) prior to the Required Company Stockholder Vote,
furnishing nonpublic information to or entering into discussions or negotiations
with, any person or entity that makes an unsolicited Superior Proposal (as
defined below), if, and only to the extent that, (a) such action is so required
under applicable law in order for the Board of Directors to comply with its
applicable fiduciary duties to its stockholders imposed by law, (b) prior to
first furnishing nonpublic information to, or first entering into substantive
discussions and negotiations with, such person or entity after the date hereof,
the Company (I) (x) releases Parent from the two-year standstill provisions of
the Confidentiality Agreement with respect to any proposal submitted by Parent
to the Company's Board of Directors for a transaction that, by the proposal's
terms, would only be consummated with the cooperation and approval of the
Company's Board of Directors (which proposal shall be submitted by Parent on a
confidential basis unless the Company or such person or entity proposing the
Superior Proposal publicly discloses the Superior Proposal), and (y) provides
written notice to Parent to the effect that it intends to furnish information
to, or enter into discussions or negotiations with, such person or entity, and
naming and identifying the person or entity making the Superior Proposal, and
(II) receives from such person or entity an executed confidentiality and
standstill agreement with terms no less favorable to the Company than the
Confidentiality Agreement entered into with Parent, as modified by clause (I)(x)
of this sentence, and (c) the Company provides Parent with all non-public
information to be provided to such person or entity which Parent has not
previously received from the Company, and the Company keeps Parent informed, on
a daily or more regular basis if the context requires or Parent so requests, of
the status, terms and conditions and all other material information with respect
to any such discussions or negotiations; and (ii) to the extent applicable,
complying with Rule 14e-2 or 14d-9 promulgated under the 1934 Act with regard to
a proposed Alternative Transaction. Nothing in this section shall (x) permit the
Company to terminate this Agreement (except as specifically provided in Article
7 hereof), or (y) permit the Company to enter into any agreement providing for
an Alternative Transaction (other than the confidentiality and standstill
agreement as provided, and in the circumstances and under the conditions set
forth, above) for as long as this Agreement remains in effect. For purposes of
this Agreement, a "Superior Proposal" shall mean a proposal for an Alternative
Transaction that the Board of Directors of the Company has reasonably and in
good faith determined (with the advice of its financial advisors and taking into
account all legal, financial and regulatory aspects of the likelihood of the
consummation of such Alternative Transaction, including, but not limited to, the
conditions to consummation and the consequences under such Alternative
Transaction proposal of any material adverse effects or changes in the Company)
to be more favorable to the Company's stockholders than the transactions
contemplated by this Agreement.

         5.4  Access and Information.

                  (a) Except as required pursuant to any confidentiality
agreement or similar agreement or arrangement to which the Company or any of its
Subsidiaries is a party (in which case the Company shall use commercially
reasonable efforts to provide acceptable alternative arrangements, not in

<PAGE>

violation of such agreement or arrangement, for disclosure to Parent or its
advisors) or pursuant to applicable law, the Company shall afford to Parent, and
to Parent's accountants, officers, directors, employees, counsel, and other
representatives, reasonable access during normal business hours upon reasonable
prior notice, from the date hereof through the Effective Time, to all of its
properties, books, contracts, commitments, and records, and, during such period,
the Company shall furnish promptly to Parent all information concerning the
Company's and its Subsidiaries' businesses, prospects, properties, liabilities,
results of operations, financial condition, testing, clinical trials, officers,
employees, investigators, distributors, customers, suppliers, and others having
material dealings with the Company as Parent may reasonably request and
reasonable opportunity to contact and obtain information from such officers,
employees, investigators, distributors, customers, suppliers, and others having
dealings with the Company as Parent may reasonably request. During the period
from the date hereof to the Effective Time, the parties shall in good faith meet
and correspond on a regular basis for mutual consultation concerning the conduct
of the Company's and the Subsidiaries' businesses and, in connection therewith,
Parent shall be entitled, during normal business hours upon reasonable prior
notice and in a manner that does not unreasonably interfere with the Company's
business, to have employees or other representatives present at the offices of
the Company and its Subsidiaries to observe, and be kept informed concerning,
the Company's and the Subsidiaries' operations and business planning.

                  (b) Parent shall hold in confidence all such nonpublic
information as required by and in accordance with the confidentiality agreement
dated November 13, 1998, between Parent and the Company (the "Confidentiality
Agreement").

         5.5  Approval of Stockholders; Proxy Statement; Registration Statement.

                  (a) The Company shall promptly take all action necessary in
accordance with the DGCL and the Company's Certificate of Incorporation and
Bylaws to cause a special meeting of the Company's stockholders (the "Company
Stockholders Meeting") to be duly called and held as soon as reasonably
practicable following the date upon which the Registration Statement (as defined
below) becomes effective for the purpose of voting upon the Merger and the
adoption and approval of this Agreement and at such Meeting to submit this
Agreement and the Merger to a vote of the stockholders. The stockholder vote or
consent required for adoption and approval of this Agreement and the approval of
the Merger shall be no greater than that set forth in the DGCL and the Company's
Certificate of Incorporation as previously provided to Parent. Accordingly, the
Company represents and warrants that the affirmative vote of the holders of
record of a majority of the shares of Company Common Stock outstanding on the
record date for the Company Stockholders Meeting is all that is necessary to
obtain stockholder adoption and approval of this Agreement and approval of the
Merger. The Company shall use best efforts to obtain the adoption and approval
by the Company's stockholders of this Agreement and the approval by the
Company's stockholders of the Merger, unless otherwise required under applicable
law in order for the Board of Directors to comply with its applicable fiduciary
duties to its stockholders imposed by law. In accordance therewith, the Company
shall, with the cooperation of Parent, prepare and file, as soon as reasonably
practicable, a proxy statement/prospectus included as part of the Registration
Statement (such proxy statement/prospectus, together with notice of meeting,

<PAGE>

form of proxy, and any letter or other materials to the Company's stockholders
included therein are referred to in this Agreement as the "Proxy
Statement/Prospectus"). Parent shall furnish to the Company all information
concerning Parent and its subsidiaries, officers, directors and shareholders,
and shall take such other action and otherwise cooperate, as the Company may
reasonably request in connection with any such action. The Company shall use
best efforts to cause the definitive Proxy Statement/Prospectus to be mailed to
the stockholders of the Company, as soon as reasonably practicable after the
Registration Statement shall have become effective, with the date of mailing as
mutually determined by the Company and Parent. The Proxy Statement/Prospectus
shall include the recommendation of the Company's Board of Directors in favor of
the Merger, unless otherwise required under applicable law in order for the
Board of Directors to comply with its applicable fiduciary duties to its
stockholders imposed by law. Unless and until this Agreement is validly
terminated pursuant to Article 7, nothing herein shall limit or eliminate in any
way the Company's obligation to call, give notice of, convene and hold the
Company Stockholders Meeting and at such meeting submit this Agreement and the
Merger to a vote of the Company's stockholders (and not postpone or adjourn such
meeting or the vote by the Company's stockholders upon this Agreement and the
Merger to another date without Parent's approval, not to be unreasonably
withheld if and only to the extent such postponement or adjournment is required
by law or by SEC or Nasdaq regulation).

                  (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 in the
Merger (the "Registration Statement"), which Registration Statement shall
include the Proxy Statement/Prospectus. Parent will use commercially reasonable
efforts to have the Registration Statement declared effective by the SEC as
promptly thereafter as practicable. Parent shall also take any action required
to be taken under state blue sky or securities laws in connection with the
issuance of Parent Common Stock pursuant to the Merger. The Company shall
furnish to Parent all information concerning the Company and its Subsidiaries
and the holders of its capital stock, and shall take such other action and
otherwise cooperate, as Parent may reasonably request in connection with any
such action.

                  (c) Parent shall notify the Company promptly (i) of the
receipt of the comments of the SEC, (ii) of any request by the SEC for
amendments or supplements to the Registration Statement, (iii) of the time when
the Registration Statement has become effective or any supplement or amendment
has been filed, or the issuance of any stop order and (iv) of the suspension of
the qualification of the Parent Common Stock issuable in connection with the
Merger for offering or sale in any jurisdiction and shall supply the Company
with copies of all correspondence with the SEC with respect to the Registration
Statement.

                  (d) If at any time prior to the Effective Time, any event or
circumstance relating to the Company, any Subsidiary, or the Company's officers
or directors should occur and be discovered by the Company that is required to
be described in an amendment or supplement to the definitive Proxy
Statement/Prospectus or the Registration Statement, the Company shall promptly
inform Parent. If at any time prior to the Effective Time, any event or
circumstance relating to Parent or any of its subsidiaries or their respective
officers or directors should occur and be discovered by Parent that is required

<PAGE>

to be described in an amendment or supplement to the definitive Proxy
Statement/Prospectus or the Registration Statement, Parent shall promptly inform
the Company. Whenever any event occurs that should be described in an amendment
of, or supplement to, the definitive Proxy Statement/Prospectus or the
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 acceptable amendment
or supplement. The parties shall promptly file such amendment or supplement with
the SEC and mail such amendment or supplement as soon as practicable after it is
cleared by the SEC. No amendment or supplement to the Proxy Statement/Prospectus
or the Registration Statement will be made by Parent or the Company without the
approval of the other party (such approval not to be unreasonably withheld or
delayed).

         5.6 Consents. The Company will, at its cost and expense, use
commercially reasonable efforts to obtain all material approvals and consents of
all third parties necessary on the part of the Company or its Subsidiaries to
consummate the transactions contemplated hereby. Parent agrees to cooperate with
the Company in connection with obtaining such approvals and consents. Parent
will, at its cost and expense, use commercially reasonable efforts to obtain all
material approvals and consents of all third parties necessary on the part of
Parent to consummate the transactions contemplated hereby. The Company and
Parent agree to cooperate with each other in connection with obtaining such
approvals and consents.

         5.7  Affiliates' Letters.

                  (a) The Company has delivered to Parent a list of names and
addresses of those persons, in the Company's reasonable judgment after
consultation with outside legal counsel, who, as of the date hereof, are
affiliates within the meaning of Rule 145 of the rules and regulations
promulgated under the 1933 Act or otherwise applicable SEC accounting releases
with respect to pooling-of-interests accounting treatment (each such person, an
"Affiliate") of the Company. The Company shall provide Parent such information
and documents as Parent shall reasonably request for purposes of reviewing such
list and shall promptly update such list to reflect any changes thereto. The
Company has delivered or caused to be delivered, or will, promptly after the
execution hereof, deliver or cause to be delivered, to Parent an affiliate's
letter in the form attached hereto as EXHIBIT B, executed by each of the
Affiliates of the Company identified in the foregoing list, who were available,
and shall use reasonable best efforts to deliver or cause to be delivered to
Parent as soon as practicable after the date hereof such an affiliate's letter
executed by any Affiliate who was not available to sign and deliver such letter
on or prior to the date hereof and by any additional persons who, to the
knowledge of the Company, become Affiliates after the date hereof. Parent shall
be entitled to place legends as specified in such affiliates' letters on the
certificates evidencing any of the Parent Common Stock received by such
Affiliates pursuant to the terms of this Agreement, and to issue appropriate
stop transfer instructions to the transfer agent for the Parent Common Stock,
consistent with the terms of such letters.


<PAGE>

                  (b) For so long as resales of shares of Parent Common Stock
issued pursuant to the Merger are subject to the resale restrictions set forth
in Rule 145 under the 1933 Act, Parent will use commercially reasonable efforts
to comply with Rule 144(c)(1) under the 1933 Act.

         5.8 Expenses. Whether or not the Merger is consummated, all costs and
expenses incurred in connection with this Agreement, the transactions
contemplated hereby, the Proxy Statement/Prospectus, and the Registration
Statement will be paid by the party incurring such costs and expenses, except
that the Company and Parent will share equally the cost of printing and filing
with the SEC the Proxy Statement/Prospectus and the Registration Statement and
the filing fees required under the HSR Act or any Foreign Merger Laws.

         5.9 Further Actions. Subject to the terms and conditions herein
provided and without being required to waive any conditions herein (whether
absolute, discretionary, or otherwise), each of the parties hereto agrees to use
commercially 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 time after the Effective Time any further action is necessary or
desirable to carry out the purposes of this Agreement, the proper officers and
directors of each party to this Agreement shall take all such necessary action.

         5.10 Regulatory Approvals.

                  (a) The Company and Parent each agree to use commercially
reasonable efforts to take, or cause to be taken, all appropriate action, and
do, or cause to be done, all things 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 soon as reasonably practicable and, if appropriate, use
commercially reasonable efforts to have declared effective or approved all
documents and notifications with the SEC and other governmental or regulatory
bodies (including, without limitation, the FDA and equivalent foreign regulatory
bodies, and other foreign regulatory bodies that administer Foreign Merger Laws,
and any foreign labor councils or bodies as may be required) that they deem
necessary or appropriate for, the consummation of the Merger or any of the other
transactions contemplated hereby, and each 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 to take such actions.

                  (b) Although the parties do not anticipate any legislative,
administrative or judicial objection to the consummation of the Merger or any of
the transactions contemplated by this Agreement, each of the Company, Parent and
Merger Subsidiary agrees to use commercially reasonable efforts vigorously to
contest and resist any action, including legislative, administrative or judicial
action, and to have vacated, lifted, reversed or overturned any decree,
judgment, injunction or other order (whether temporary, preliminary or
permanent) (an "Order") that is in effect and that restricts, prevents or
prohibits the consummation of the Merger or any of the other transactions
contemplated by this Agreement, including, without limitation, by vigorously
pursuing available avenues of administrative and judicial appeal. Each of the
Company, Parent and Merger Subsidiary also agrees to use commercially reasonable
efforts to take any and all actions necessary to avoid or eliminate each and

<PAGE>

every impediment under any antitrust law that may be asserted by any
governmental antitrust authority or any other party so as to enable the parties
to close by the date specified in Section 7.1(b) the transactions contemplated
hereby, including without limitation, committing to and/or effecting, by consent
decree, hold separate orders, or otherwise, the sale or disposition of such
assets or businesses as are required to be divested in order to avoid the entry
of, or to effect the dissolution of, any injunction, temporary restraining order
or other order in any suit or proceeding, which would otherwise have the effect
of preventing the consummation by the date specified in Section 7.1(b) of all or
any material part of the transactions contemplated hereby. Notwithstanding the
foregoing or anything herein to the contrary, in no event shall any party hereto
be required under this Section 5.10 to make arrangements for or to effect the
sale, cessation, or other disposition of product lines or businesses or take any
action materially adverse to such party.

         5.11 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 any of the
conditions specified in Section 6.1 or 6.2. Parent shall promptly notify the
Company in writing of the occurrence of any event that will or could reasonably
be expected to result in the failure by Parent or its affiliates to satisfy any
of the conditions specified in Section 6.1, 6.2(e) or 6.3.

         5.12 Voting of Shares. To induce Parent to execute this Agreement,
certain executive officers and directors of the Company included in the list of
"Affiliates" referenced in Section 5.7 have executed and delivered as of the
date hereof Agreements to Facilitate Merger in the form attached hereto as
EXHIBIT C (the "Agreement to Facilitate Merger"), pursuant to which each such
person has agreed to vote his or her shares of Company Common Stock in favor of
the Merger at the Company Stockholders Meeting. The Company will use reasonable
best efforts to have all other such Affiliates execute and deliver to Parent
Agreements to Facilitate Merger as soon as practicable after the date hereof.

         5.13 Stock Option Agreement. To induce Parent to execute this
Agreement, the Company has executed and delivered to Parent as of the date
hereof a Stock Option Agreement in the form attached hereto as EXHIBIT D (the
"Stock Option Agreement"), pursuant to which the Company has granted to Parent
an option to acquire from the Company 12,807,795 shares of Company Common Stock
at an exercise price equal to $54.00 per share. Such option shall become
exercisable only in the events described in the Stock Option Agreement.

         5.14 NYSE Listing Application. Parent shall promptly prepare and submit
to the NYSE a listing application for the Parent Common Stock to be issued in
the Merger pursuant to Article 1 of this Agreement and pursuant to the Company
Options assumed by Parent, and shall use commercially reasonable efforts to
obtain, prior to the Effective Time, approval for the listing of such Parent
Common Stock, subject to official notice to the NYSE of issuance. The Company
shall cooperate with Parent in such listing application.


<PAGE>

         5.15 Indemnification.

                  (a) The certificate of incorporation and the bylaws of the
Surviving Corporation shall contain the provisions with respect to
indemnification, payment of fees and expenses and exculpation from liability set
forth in the Company's certificate of incorporation and bylaws on the date of
this Agreement, which provisions shall not be amended, repealed or otherwise
modified for a period of six years from the Effective Time in any manner that
would adversely affect the rights thereunder of individuals who on or at any
time prior to the Effective Time were directors, officers, employees or agents
of the Company (the "Indemnified Parties"), unless such modification is required
by law. From and after the Effective Time, Parent will cause the Surviving
Corporation to fulfill and honor in all respects the obligations of the Company
pursuant to each indemnification agreement in effect between the Company and an
Indemnified Party. Parent shall guarantee the obligations of the Surviving
Corporation with respect to the indemnification and payment of fees and expenses
provisions contained in the Surviving Corporation's certificate of incorporation
and bylaws and in the indemnification agreements described in the Company
Disclosure Schedule in effect between the Company and an Indemnified Party as of
the Effective Time with respect to acts occurring at or before the Effective
Time (including the transactions contemplated by this Agreement).

                  (b) For a period of six years after the Effective Time, Parent
shall cause to be maintained in effect the Company's current directors' and
officers' liability insurance policy with respect to claims arising from facts
or events that occurred at or prior to the Effective Time; provided, however,
that (i) Parent may substitute therefor policies providing coverage on terms and
conditions that are no less advantageous to the Indemnified Parties, and (ii)
Parent may satisfy its obligations hereunder by extending the discovery or
reporting period under such policy for six years from the Effective Time to
maintain in effect directors' and officers' liability insurance covering
pre-acquisition acts (including acts in connection with this Agreement and the
transactions contemplated hereby) for the Indemnified Parties on terms no less
favorable than the terms of such current insurance coverage; provided, however,
that in no event shall Parent be required to expend for any such coverage an
amount per year in excess of $798,000; and provided further that if the cost per
year of such coverage exceeds $798,000, Parent shall be obligated to obtain such
coverage as is available for a cost per year not exceeding such amount. The
Company represents that the annual premium currently paid by the Company for
such insurance is approximately $399,000.

                  (c) In the event Parent, the Surviving Corporation or any of
their successors or assigns (i) consolidates with or merges into any other
person or entity and shall not be the continuing or surviving corporation or
entity of such consolidation or merger or (ii) transfers all or substantially
all of its properties and assets to any person, then and in each such case,
proper provisions shall be made so that the successors and assigns of Parent or
the Surviving Corporation, as the case may be, shall assume the obligations set
forth in this Section 5.15.

                  (d) This Section 5.15 shall survive the consummation of the
Merger at the Effective Time, is intended to benefit the Indemnified Parties,
may be enforced by the Indemnified Parties as third party beneficiaries and

<PAGE>

shall be binding on all successors and assigns of Parent and the Surviving
Corporation.

         5.16 Letters of the Company's and Parent's Accountants.

                  (a) The Company shall cooperate with Parent and use reasonable
best efforts to cause to be delivered to Parent and the Company, letters from
Ernst & Young LLP addressed to the Company, as of the Closing Date, stating that
based upon discussions with officials of the Company responsible for financial
and accounting matters, and information furnished to Ernst & Young LLP to the
date of its letter, Ernst & Young LLP concurs with the Company's management's
conclusion that, as of the date of its letter, no conditions exist related to
the Company that would preclude Parent's accounting for the merger with the
Company as a pooling of interests.

                  (b) The Company shall cooperate with Parent and Parent shall
use reasonable best efforts to cause to be delivered to the Company and Parent,
letters from PricewaterhouseCoopers LLP addressed to Parent, dated as of the
Closing Date, confirming as of the Closing Date that the Merger will qualify as
a pooling of interests transaction under Opinion 16 of the Accounting Principles
Board and applicable SEC rules and regulations.

         5.17 Subsidiary Shares. At or prior to the Closing, the Company shall
use commercially reasonable efforts to cause all issued and outstanding
Subsidiary shares (other than any interests in joint ventures or similar
arrangements) owned by any person other than the Company or any of its
Subsidiaries to be transferred for no or nominal consideration to such qualified
person or persons designated by Parent.

         5.18 Benefit Plans and Employee Matters.

                  (a) From and after the Effective Time, Parent shall to the
extent practicable cause the Surviving Corporation to provide employee benefits
and programs to the Company's and its Subsidiaries' employees that, in the
aggregate, are substantially comparable to or more favorable than those in
existence as of the date hereof and disclosed in writing to Parent prior to the
date hereof; provided that stock-based compensation shall be comparable, in the
aggregate, to that offered by Parent and its subsidiaries generally. To the
extent Parent satisfies its obligations under this Section by maintaining
Company benefit plans, Parent shall not be required to include employees of the
Company in Parent's benefit plans. From and after the Effective Time, Parent
shall honor, in accordance with their terms, all employment and severance
agreements and all severance, incentive and bonus plans as in effect immediately
prior to the Closing Date that are applicable to any current or former employees
or directors of the Company or any of its Subsidiaries and that are disclosed in
the Company Disclosure Schedule.

                  (b) To the extent that service is relevant for purposes of
eligibility, level of participation, or vesting under any employee benefit plan,
program or arrangement established or maintained by Parent, the Company or any
of their respective subsidiaries, employees of the Company and its Subsidiaries
shall be credited for service accrued or deemed accrued prior to the Effective
Time with the Company or such Subsidiary, as the case may be. Under no

<PAGE>

circumstances shall employees receive credit for service accrued or deemed
accrued prior to the Effective Time with the Company or such Subsidiary, as the
case may be, for benefit accruals under any employee pension benefit plan (as
defined by Section 3(2) of ERISA) or any retiree health plan.

                  (c) As soon as reasonably practicable after the Effective
Time, Parent shall take whatever action is reasonably necessary to provide for a
special phase under Parent's employee stock purchase plan (the "Parent ESPP") to
permit those employees of the Surviving Corporation who have satisfied the
eligibility requirements of the Parent ESPP to purchase Parent Common Stock
under the Parent ESPP, with such phase to be operated under the terms and
conditions of the Parent ESPP.

         5.19 Obligations of Merger Subsidiary. Parent shall take all action
necessary to cause Merger Subsidiary to perform its obligations under this
Agreement and to consummate the Merger on the terms and subject to the
conditions set forth in this Agreement.

         5.20 Plan of Reorganization. This Agreement is intended to constitute a
"plan of reorganization" within the meaning of Section 1.368-2(g) of the income
tax regulations promulgated under the Code. From and after the date of this
Agreement and after the Effective Time, each party hereto shall use reasonable
best efforts to cause the Merger to qualify, and shall not, without the prior
written consent of the other parties hereto, knowingly take any actions or cause
any actions to be taken which could prevent the Merger from qualifying as a
reorganization under the provisions of Section 368(a) of the Code.

Effective Time, neither Parent nor the Company, nor any of their respective
subsidiaries or other affiliates, shall knowingly take any action, or knowingly
fail to take any action, that is reasonably likely to jeopardize the treatment
of the Merger as a "pooling of interests" for accounting purposes. Between the
date of this Agreement and the Effective Time, Parent and the Company each shall
use reasonable best efforts to cause the characterization of the Merger as a
pooling of interests for accounting purposes if such a characterization were
jeopardized by action taken by Parent or the Company, respectively, prior to the
Effective Time. Following the Effective Time, Parent shall not knowingly take
any action, or fail to take any action, that would jeopardize the
characterization of the Merger as a "pooling of interests" for accounting
purposes.

         5.22 Tax Matters. At or prior to the filing of the Registration
Statement and at or prior to the Closing, the Company and Parent shall execute
and deliver to Cooley Godward LLP and to Fredrikson & Byron, P.A. tax
representation letters reasonably satisfactory to such counsel setting forth
customary representations which may be relied upon by such counsel in rendering
any opinions contemplated by this Agreement. Parent shall use commercially
reasonable efforts to cause Fredrikson & Byron, P.A. to deliver to Parent a
legal opinion, satisfying the requirements of Item 601 of Regulation S-K
promulgated under the 1933 Act and dated as of a date that is no more than two
business days prior to the date of filing of the Registration Statement, to the
effect that the Merger will constitute a reorganization within the meaning of
Section 368(a) of the Code, based in part on the tax representation letters

<PAGE>

described in this Section 5.22. The Company shall use commercially reasonable
efforts to cause Cooley Godward LLP to deliver to the Company a legal opinion,
satisfying the requirements of Item 601 of Regulation S-K promulgated under the
1933 Act and dated as of a date that is no more than two business days prior to
the date of filing of the Registration Statement, to the effect that the Merger
will constitute a reorganization within the meaning of Section 368(a) of the
Code, based in part on the tax representation letters described in this Section
5.22.

Company shall be subject to any final order, decree, or injunction of a court of

has the effect of making the Merger illegal or otherwise prohibiting the
consummation of the Merger, or (ii) would impose any material limitation on the

address matters only as of the date hereof or another particular date shall
remain true and correct as of such date, and except in any case for any
inaccuracies that have not had, or would not reasonably be expected to have, a
Company Material Adverse Effect; provided, however, notwithstanding the
foregoing, this Section 6.2(a) shall not be considered fulfilled or satisfied if
the representation and warranty set forth in the last sentence of Section 3.3 is
incorrect as of the Closing Date by understating the number of shares of Company
Common Stock by more than 20,000 shares. Parent shall have received a

in all material respects with all material covenants required by this Agreement
to be performed or complied with by it at or prior to the Closing, and Parent

Officer of the Company or other authorized Officer of the Company (provided that
for purposes of this subsection (b), actions of representatives or agents of the
Company who are not officers, directors or employees of the Company which do not
result in a proposal for an Alternative Transaction shall not be deemed to be a
breach of Section 5.3 so long as the Company has used commercially reasonable
efforts to cause such representatives and agents to comply with Section 5.3).

                  (c) Affiliates' Letters. Parent shall have received a letter

be waived by the Company, in whole or in part, to the extent permitted by
applicable law:

                  (a) Representations and Warranties True. Each representation
and warranty of Parent contained in this Agreement, without regard to any
qualification or reference to "Parent Material Adverse Effect," shall be true
and correct on the Closing Date as though such representations and warranties
were made on such date, except that those representations and warranties that

<PAGE>

address matters only as of the date hereof or another particular date shall
remain true and correct as of such date, and except in any case for any
inaccuracies that have not had, or would not reasonably be expected to have a
Parent Material Adverse Effect. The Company shall have received a certificate to
the foregoing effect signed by the Chief Executive Officer or other authorized
officer of Parent.

                  (b) Performance. Parent and Merger Subsidiary shall have

stockholders, based upon representations of Parent, Merger Subsidiary and the
Company and normal assumptions, and dated on or about the date that is two
business days prior to the date the Proxy Statement/Prospectus is first mailed
to Company's stockholders, which opinion shall not have been withdrawn or
modified in any material respect prior to the Effective Time, to the effect
that, subject to customary conditions and representations, the Merger will be
treated for federal income tax purposes as a reorganization within the meaning
of Section 368(a) of the Code, and that each of Parent, Merger Subsidiary and
the Company will be considered a party to such reorganization. Parent, Merger
Subsidiary and the Company hereby agree to provide to such counsel certificates
acceptable to such counsel setting forth the customary representations which may
be relied upon by such counsel in rendering such opinion.

                  (d) Pooling  Opinion.  The Company shall have  received each

                                    ARTICLE 7

                           TERMINATION AND ABANDONMENT

         7.1 Termination. This Agreement may be terminated at any time prior to
the Effective Time, whether before or after approval by the stockholders of the
Company, only:

                  (a) by mutual written consent duly authorized by the Board of
Directors of Parent and the Board of Directors of the Company;

                  (b) by either Parent or the Company if the Merger shall not
have been consummated on or before May 31, 1999; provided, however, that the
terminating party shall not have breached in any material respect its
obligations under this Agreement in any manner that shall have been the
proximate cause of, or resulted in, the failure to consummate the Merger by such
date and provided further, however, that, if a request for additional
information is received from the U.S. Federal Trade Commission ("FTC") or
Department of Justice ("DOJ") pursuant to the HSR Act or additional information
is requested by a governmental authority (a "Foreign Authority") pursuant to
Foreign Merger Laws, such date shall be extended to the 90th day following

<PAGE>

acknowledgment by the FTC, DOJ, or Foreign Authority, as applicable, that Parent
and the Company have complied with such request, but in any event not later than
October 31, 1999;

                  (c) by either Parent or the Company if a court of competent
jurisdiction or an administrative, governmental, or regulatory authority has
issued a final nonappealable order, decree, or ruling, or taken any other
action, having the effect of permanently restraining, enjoining, or otherwise
prohibiting the Merger;

                  (d) by either Parent or the Company if, at the Company
Stockholders Meeting, the requisite vote of the stockholders of the Company for
approval and adoption of this Agreement and the Merger is not obtained, except
that the right to terminate this Agreement under this Section 7.1(d) 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 stockholders of the Company;

                  (e) by Parent if either (i) the Company has breached its
obligations under Section 5.3 in any material respect (provided that for
purposes of this clause (i), actions of representatives or agents of the Company
who are not officers, directors or employees of the Company which do not result
in a proposal for an Alternative Transaction shall not be deemed to be a breach
of Section 5.3 so long as the Company has used commercially reasonable efforts
to cause such representatives and agents to comply with Section 5.3), (ii) the
Board of Directors of the Company has recommended, approved, or authorized the
Company's acceptance or execution of a definitive agreement providing for an
Alternative Transaction, as defined in Section 5.3, (iii) the Board of Directors
of the Company has modified in a manner materially adverse to Parent or
withdrawn its recommendation of this Agreement, or (iv) a tender offer or
exchange offer for any outstanding shares of Company Common Stock is commenced,
and the Board of Directors of the Company, within 10 business days after such
tender offer or exchange offer is so commenced, either fails to recommend
against acceptance of such tender offer or exchange offer by its stockholders or
takes no position with respect to the acceptance of such tender offer or
exchange offer by its stockholders;

                  (f) by the Company prior to the Required Company Stockholder
Vote if (i) it is not in breach of its obligations under Section 5.5 in any
material respect and has complied with, and continues to comply with, all
requirements and procedures of Section 5.3 in all material respects, (ii) the
Board of Directors of the Company has complied with, and continues to comply
with, all requirements and procedures of Section 5.3 in all material respects
and has authorized, subject to complying with the terms of this Agreement, the
Company to enter into a binding written agreement concerning a transaction that
constitutes a Superior Proposal and the Company notifies Parent in writing that
it intends to enter into such agreement, attaching the most current version of
such agreement to such notice, (iii) Parent does not make, within ten business
days after receipt of the Company's written notice of its intention to enter
into a binding agreement for a Superior Proposal, any offer that the Board of
Directors of the Company reasonably and in good faith determines, after
consultation with its financial and legal advisors, is at least as favorable to
the stockholders of the Company as the Superior Proposal and during such ten

<PAGE>

business-day period the Company reasonably considers and discusses in good faith
all proposals submitted by Parent and, without limiting the foregoing, meets
with, and causes its financial advisors and legal advisors to meet with, Parent
and its advisors from time to time as requested by Parent to reasonably consider
and discuss in good faith Parent's proposals, and (iv) prior to the Company's
termination pursuant to this Section 7.1(f), the Company pays to Parent the fee
required by Section 7.2 to be paid to Parent in the manner therein provided. The
Company agrees (x) that it will not enter into a binding agreement referred to
in clause (ii) above until at least the 11th business day after Parent has
received the notice to Parent required by clause (ii) above, and (y) to notify
Parent promptly if its intention to enter into a binding agreement referred to
in its notice to Parent shall change at any time after giving such notice;

                  (g) by Parent if (i) Parent is not in material breach of its
obligations under this Agreement and (ii) there has been a material breach by
the Company of any of its representations, warranties, or obligations under this
Agreement such that the conditions in Section 6.2 will not be satisfied
("Terminating Company Breach"); provided, however, that, if such Terminating
Company Breach is curable by the Company through the exercise of reasonable best
efforts and such cure is reasonably likely to be completed prior to the
applicable date specified in Section 7.1(b), then for so long as the Company
continues to exercise reasonable best efforts, Parent may not terminate this
Agreement under this Section 7.1(g); and provided further that for purposes of
this subsection (g), actions of representatives or agents of the Company who are
not officers, directors or employees of the Company which do not result in a
proposal for an Alternative Transaction shall not be deemed to be a breach of
Section 5.3 so long as the Company has used commercially reasonable efforts to
cause such representatives and agents to comply with Section 5.3); or

                  (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 ("Terminating Parent Breach"); provided, however, that, if such
Terminating Parent Breach is curable by Parent through the exercise of
reasonable best efforts and such cure is reasonably likely to be completed prior
to the applicable date specified in Section 7.1(b), then for so long as Parent
continues to exercise reasonable best efforts, the Company may not terminate
this Agreement under this Section 7.1(h).

                  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 that the
acquisition of the Company presents to Parent, if:

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

                           (ii) (A) this Agreement is validly terminated by
                  Parent or the Company pursuant to Section 7.1(d) due to the
                  failure of the Company's stockholders to approve the Merger,

<PAGE>

                  (B) at any time between the date hereof and the time of such
                  failure to so approve the Merger, a proposal for a Competing
                  Transaction shall have been publicly announced, (C) within 12
                  months after the date of such termination, the Company shall
                  have entered into a definitive agreement with a Third Party
                  providing for a Competing Transaction, and (D) a Competing
                  Transaction is consummated by the Company with the same Third
                  Party that entered into the definitive agreement referenced in
                  clause (C) above or any affiliate of such Third Party within
                  two years after entering into the agreement referenced in
                  clause (C) above;

then, in any such event (but subject to Section7.2(c)), 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), or within five business days after
consummating the Competing Transaction referenced in clause (ii) (D) above 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 $135,000,000. For purposes of this Agreement,
"Competing Transaction" means: (i) any consolidation, exchange of shares or
merger of the Company with any Third Party, other than a consolidation, exchange
or shares or merger as a result of which the holders of Company Common Stock
immediately prior to such transaction beneficially own 50% or more of the voting
stock of the Company, the surviving corporation or any parent entity immediately
after the transaction, (ii) any transaction or series of related transactions
pursuant to which a Third Party acquires shares (or securities exercisable for
or convertible into shares) representing more than 50% of the outstanding shares
of any class of capital stock of the Company; or (iii) any sale, lease,
exchange, licensing, transfer or other disposition pursuant to which a Third
Party acquires control of more than 50% of the assets (including, but not
limited to, intellectual property assets) of the Company and its Subsidiaries
taken as a whole (determined by reference to the fair market value of such
assets), in a single transaction or series of related transactions.

                  (b) The Company acknowledges that the agreements contained in
this Section 7.2 are an integral part of the transactions contemplated by this
Agreement and are not a penalty, and that, without these agreements, Parent
would not enter into this Agreement. If the Company fails to pay promptly the
fee due pursuant to Section 7.2(a), the Company shall also pay to Parent
Parent's costs and expenses (including legal fees and expenses) in connection
with any action, including the filing of any lawsuit or other legal action,
taken to collect payment, together with interest on the amount of the unpaid fee
under this section, accruing from its due date, at an interest rate per annum
equal to two percentage points in excess of the prime commercial lending rate
quoted by Norwest Bank Minnesota, N.A.; provided, however, that Parent shall pay
to the Company the Company's costs and expenses (including legal fees and
expenses) incurred in connection with any such legal action if Parent's claims
against the Company in such legal action do not prevail. 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.

                  (c) Parent agrees that the payment provided for in Section
7.2(a) shall be the sole and exclusive remedy of Parent upon termination of this
Agreement pursuant to Section 7.1(e) and 7.1(f), as the case may be, and such

<PAGE>

remedy shall be limited to the sum stipulated in such Section 7.2(a), regardless
of the circumstances giving rise to such termination; provided, however, that
nothing herein shall relieve any party from liability for the willful breach of
any of its representations, warranties, covenants or agreements set forth in
this Agreement. In no event shall the Company be required to pay to Parent more
than one fee pursuant to Section 7.2(a). In no event shall the sum of (i) the
termination fee paid pursuant to Section 7.2(a), (ii) the Cancellation Amount
(as defined in the Stock Option Agreement) paid pursuant to the Stock Option
Agreement, (iii) the aggregate Option Share Profit (as defined in the Stock
Option Agreement) not remitted to the Company pursuant to Section 2(c) of the
Stock Option Agreement, and (iv) the Section 5 Repurchase Consideration (as
defined in the Stock Option Agreement) paid to Parent exceed $150,000,000. In
addition, the fee payable by the Company pursuant to Section 7.2(a) shall be
reduced (but not below zero) by any Cancellation Amount paid pursuant to the
Stock Option Agreement, any Option Share Profit not remitted to the Company
pursuant to Section 2(c) of the Stock Option Agreement and any Section 5
Repurchase Consideration paid pursuant to the Stock Option Agreement. Except as
provided in the next sentence of this paragraph, in 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 Sections
5.4(b), 5.8, 7.2(a), 7.2(b) and 7.2(c) and Article 8. Nothing herein shall
relieve any party from liability for the willful breach of any of its
representations, warranties, covenants or agreements set forth in this
Agreement.

                                    ARTICLE 8

                                  MISCELLANEOUS

         8.1 Amendment and Modification. Subject to applicable law, this
Agreement may be amended, modified, or supplemented only by written agreement of
Parent, Merger Subsidiary, and the Company at any time prior to the Effective
Time with respect to any of the terms contained herein; provided, however, that,
after the approval of this Agreement by the stockholders of the Company, no
amendment may be made which would reduce the amount or change the type of
consideration into which each share of Company Common Stock shall be converted
upon consummation of the Merger or which would otherwise require stockholder
approval under applicable law unless such stockholder approval shall have been
obtained. This Agreement may not be amended except by an instrument in writing
signed on behalf of each of the parties hereto.

         8.2 Waiver of Compliance; Consents. Any failure of Parent or Merger
Subsidiary on the one hand, or the Company on the other hand, to comply with any
obligation, covenant, agreement, or condition herein may be waived by the
Company or Parent, respectively, only by a written instrument signed by an
officer of the party granting such waiver, but such waiver or failure to insist
upon strict compliance with such obligation, covenant, agreement, or condition
shall not operate as a waiver of, or estoppel with respect to, any subsequent or
other failure. Whenever this Agreement requires or permits consent by or on
behalf of any party hereto, such consent shall be given in writing. Merger

<PAGE>

Subsidiary agrees that any consent or waiver of compliance given by Parent
hereunder shall be conclusively binding upon Merger Subsidiary, whether or not
given expressly on its behalf.

         8.3 Investigation; Survival of Representations and Warranties. The
respective representations and warranties of Parent and the Company contained
herein or in any certificates or other documents delivered prior to or at the
Closing shall not be deemed waived or otherwise affected by any investigation
made by any party hereto. The representations, warranties and agreements in this
Agreement and in any certificate delivered pursuant hereto shall terminate at
the Effective Time, except that the agreements set forth in Articles I and II
and Sections 5.7(b), 5.8, 5.9, 5.15, 5.18, 5.19, 5.20, 5.21 and this Article

         8.5 Assignment. This Agreement and all of the provisions hereof shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and permitted assigns, but neither this Agreement nor any
of the rights, interests, or obligations hereunder shall be assigned by any of
the parties hereto without the prior written consent of the other parties.
Except for the provisions of Article II and Section 5.15 (the "Third Party
Provisions"), this Agreement is not intended to confer upon any other person,
except the parties hereto, any rights or remedies hereunder, and no third person
shall be a third party beneficiary of this Agreement. The Third Party Provisions
may be enforced by the beneficiaries thereof.

         8.6 Governing Law. Except to the extent that Delaware law is
mandatorily applicable, this Agreement shall be governed by the laws of the
State of Minnesota (regardless of the laws that might otherwise govern under
applicable Minnesota principles of conflicts of law). The parties hereby (i)
agree and consent to be subject to the jurisdiction of any state or federal
court in the state of Delaware or in Minneapolis or St. Paul, Minnesota, with
respect to all actions and proceedings arising out of or relating to this
Agreement (although each party reserves the right to bring such action or
proceedings in any other jurisdiction to which the other party is subject); (ii)
agree that all claims with respect to any such action or proceeding may be heard
and determined in such court; (iii) irrevocably waive any defense of an
inconvenient forum to the maintenance of any action or proceeding in such court;
(iv) consent to service of process by mailing or delivering such service to the
party at its respective principal business address; and (v) agree that a final
judgment in any such action or proceeding from which there is no further appeal
shall be conclusive and may be enforced in any other jurisdictions by suit on
the judgment or in any manner provided by law.

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

         8.8 Knowledge. As used in this Agreement or the instruments,
certificates or other documents required hereunder, the term "knowledge" of a
party hereto shall mean actual knowledge of the directors or executive officers
of such party.

         8.9 Interpretation. The Table of Contents, article and section headings
contained in this Agreement are inserted for reference purposes only and shall
not affect the meaning or interpretation of this Agreement. This Agreement shall
be construed without regard to any presumption or other rule requiring the

resolution of any ambiguity regarding the interpretation or construction hereof
against the party causing this Agreement to be drafted.

         8.10 Publicity. Upon execution of this Agreement by Parent, Merger
Subsidiary, and the Company, the parties shall jointly issue a press release, as
agreed upon by them. The parties intend that all future statements or
communications to the public or press regarding this Agreement or the Merger
will be mutually agreed upon by them. Neither party shall, without such mutual
agreement or the prior consent of the other, issue any statement or
communication to the public or to the press regarding this Agreement, or any of
the terms, conditions, or other matters with respect to this Agreement, except
as required by law or the rules of the NYSE or Nasdaq and then only (a) upon the
advice of such party's legal counsel; (b) to the extent required by law or the
rules of the NYSE or Nasdaq; and (c) following prior notice to, and consultation
with, the other party (which notice shall include a copy of the proposed
statement or communication to be issued to the press or public). The foregoing
shall not restrict Parent's or the Company's communications with their employees
or customers in the ordinary course of business.

         8.11 Entire Agreement. This Agreement, including the exhibits and
schedules hereto and the Confidentiality Agreement referred to herein, embodies
the entire agreement and understanding of the parties hereto in respect of the
subject matter contained herein. This Agreement and the Confidentiality
Agreement supersede all prior agreements and the understandings between the
parties with respect to such subject matter.

         8.12 Severability. If any term or other provision of this Agreement is
invalid, illegal or incapable of being enforced by any rule of law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated by this Agreement is not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in a mutually acceptable
manner in order that the transactions contemplated by this Agreement be
consummated as originally contemplated to the fullest extent possible.

         8.13 Specific Performance. The parties hereto agree that irreparable
damage would occur in the event any provision of this Agreement was not
performed in accordance with the terms hereof and that the parties shall be
entitled to specific performance of the terms hereof, in addition to any other
remedy at law or in equity.
