                               AFFILIATE'S LETTER


Medtronic, Inc.
7000 Central Avenue, N.E.
Minneapolis, Minnesota  55432


Ladies and Gentlemen:

The undersigned officer, director and/or shareholder having the right to
designate a director of PercuSurge, Inc. (the "Company") has been advised that
the undersigned may be deemed by the Company to be an "affiliate" of the
Company, as that term is used in paragraphs (c) and (d) of Rule 145 under the
Securities Act of 1933, as amended (the "Securities Act") (such rule, as amended
or replaced by any successor rule, referred to herein as "Rule 145") and for
purposes of Accounting Series Releases 130 and 135, as amended, of the
Securities and Exchange Commission (the "SEC"). Pursuant to the terms of the
Agreement and Plan of Merger dated on or about the date hereof (the "Merger
Agreement"), among Medtronic, Inc. ("Parent"), Trojan Merger Corp. ("Merger
Subsidiary"), and the Company, Merger Subsidiary will be merged with and into
the Company (the "Merger"). As a result of the Merger, outstanding shares of
common stock, $.001 par value per share, of the Company ("Company Common Stock")
and outstanding shares of preferred stock, $.001 par value per share, of the
Company ("Company Preferred Stock") will be converted into the right to receive
shares of common stock, $.10 par value per share, of Parent ("Parent Common
Stock"), as determined pursuant to the Merger Agreement.

In order to induce Parent and the Company to enter into the Merger Agreement,
the undersigned (referred to herein as "Affiliate") represents, warrants and
agrees as follows:

1.   Affiliate will not directly or indirectly take any action that would have
     the effect of jeopardizing the treatment of the Merger as a "pooling of
     interests," sell, transfer, pledge, dispose of, or otherwise reduce
     Affiliate's risk relative to, any Parent Common Stock, Company Common
     Stock, or Company Preferred Stock during the period commencing 30 days
     prior to the effective time of the Merger and ending at such time as
     financial results covering at least 30 days of the post-Merger combined
     operations of Parent and the Company have been published by Parent, in the
     form of a quarterly earnings report, an effective registration statement
     filed with the SEC, a report to the SEC on Form 10-K, 10-Q or 8-K, or any
     other public filing or announcement which includes the combined results of
     operations.

2.   Affiliate has been advised that the issuance of the Parent Common Stock, if
     any, to Affiliate pursuant to the Merger is being registered with the SEC
     under the Securities Act and the rules and regulations promulgated
     thereunder on a Registration Statement on Form S-4. However, Affiliate has
     also been advised that, because Affiliate may be

                                       1
<PAGE>

     deemed to be an "affiliate" of the Company (as that term is used in
     paragraphs (c) and (d) of Rule 145), any sale, transfer or other
     disposition by Affiliate of any Parent Common Stock issued pursuant to the
     Merger will, under current law, require either (a) further registration
     under the Securities Act of the Parent Common Stock to be sold,
     transferred, or otherwise disposed of, (b) compliance with Rule 145, or (c)
     the availability of another exemption from such registration.

3.   Affiliate will not offer to sell, sell, or otherwise dispose of any Parent
     Common Stock issued pursuant to the Merger except pursuant to an effective
     registration statement or in compliance with Rule 145 or another exemption
     from the registration requirements of the Securities Act (the compliance
     with Rule 145 or the availability of such other exemption to be established
     by Affiliate to the reasonable satisfaction of Parent's counsel).

4.   Affiliate consents to the placement of a stop transfer order with the
     Company's and Parent's stock transfer agent and registrar, and to the
     placement of the following legend on certificates representing the Company
     Common Stock, Company Preferred Stock, or Parent Common Stock issued or to
     be issued to Affiliate:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD OR
         OTHERWISE TRANSFERRED EXCEPT IN COMPLIANCE WITH AN AFFILIATE'S
         LETTER FROM THE UNDERSIGNED TO MEDTRONIC, INC. AND PURSUANT TO
         AN EFFECTIVE REGISTRATION STATEMENT OR IN COMPLIANCE WITH RULE
           145 OF THE SECURITIES ACT OF 1933 OR ANOTHER EXEMPTION FROM
          THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933."

5.   Affiliate has carefully read this letter and has discussed with counsel for
     Affiliate or counsel for the Company, to the extent Affiliate felt
     necessary, the requirements of this letter and other applicable limitations
     on the Affiliate's ability to sell, transfer, or otherwise dispose of
     Company Common Stock, Company Preferred Stock, and Parent Common Stock.

6.   The Company agrees to take all reasonable actions up to the date of the
     Merger, including but not limited to the placement of a stop transfer order
     with the Company's stock transfer agent and registrar, to ensure compliance
     by Affiliate with the provisions of this letter.

7.   Execution of this letter should not be considered an admission on the part
     of Affiliate that Affiliate is an "affiliate" of the Company as described
     in the first paragraph of this letter, nor as a waiver of any rights that
     Affiliate may have to object to any claim that Affiliate is such an
     affiliate on or after the date of this letter.

                         AGREEMENT TO FACILITATE MERGER


DATE:        October ____, 2000

PARTIES:

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

                      and


             ---------------------------,
             an individual officer, director
             and/or shareholder having the
             right to designate a director
             of PercuSurge, Inc.                (hereinafter "Security Holder")

RECITALS:

     A. Security Holder is the legal or beneficial owner of shares of Common
Stock or Preferred Stock of PercuSurge, Inc., a Delaware corporation (the
"Company"), and/or the holder of options, warrants, or other rights to acquire
shares of Company Common Stock or Company Preferred 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. Security Holder deems it to be in Security Holder'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 obligations under the Merger
Agreement that Security Holder enter into this Agreement.

     D. It is understood and acknowledged by Security Holder that Parent's
execution of the Merger Agreement is being done in reliance, in part, upon the
contemporaneous 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
Security Holder 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
                                       1
<PAGE>

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:

AGREEMENTS:

     1. VOTE IN FAVOR OF MERGER. During the period commencing on the date hereof
and terminating upon the earlier of (i) the effective time of the Merger, and
(ii) the termination of the Merger Agreement in accordance with its terms,
Security Holder agrees to vote (or cause to be voted) all shares of Company
Common Stock and Company Preferred Stock presently beneficially owned by
Security Holder, and all shares of Company Common Stock and Company Preferred
Stock with respect to which Security Holder in the future acquires beneficial
ownership, at any meeting of the stockholders of the Company, and in 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, Security Holder
hereby revokes any and all previous proxies with respect to any shares of
Company Common Stock or Company Preferred Stock that Security Holder owns or has
the right to vote. Nothing in this Agreement shall be deemed to restrict or
limit Security Holder'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 SECURITY HOLDER. Security Holder
represents and warrants to Parent that Security Holder has the legal capacity to
enter into and perform all of Security Holder's obligations under this
Agreement. The execution, delivery, and performance of this Agreement by
Security Holder will not violate any other agreement to which Security Holder is
a party, including, without limitation, any voting agreement, stockholders
agreement, or voting trust. This Agreement has been duly executed and delivered
by Security Holder and constitutes a legal, valid, and binding agreement of
Security Holder, 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
purchasers, donees, pledgees, and other transferees of Company Common Stock or
Company Preferred Stock legally or beneficially owned by Security Holder. During
the period commencing on the date hereof and terminating upon the earlier of the
effective time of the Merger and the termination of the Merger Agreement in
accordance with its terms, Security Holder agrees not to make any sales, gifts,
transfers, pledges, or other dispositions of Company Common Stock or Company
Preferred Stock without first making any such transferee or pledgee fully aware
of Security Holder's obligations under this Agreement and obtaining such
transferee's or pledgee's written agreement to comply with all terms hereof.

     4. INJUNCTIVE RELIEF. Security Holder agrees that in the event of Security
Holder's breach of any provision of this Agreement, Parent may be without an
adequate remedy at law. Security Holder therefore agrees that in the event of
Security Holder'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

                                       2
<PAGE>

any such relief, Parent will not be precluded from seeking or obtaining any
other relief to which it may be entitled.

     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. Security Holder shall execute and deliver such
additional documents and take such further action as may be
necessary or desirable to consummate the transactions contemplated by 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 Security Holder 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 termination of the
Merger Agreement in accordance with its terms.

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

                                             Medtronic, Inc.

                             STOCK OPTION AGREEMENT


     THIS AGREEMENT is dated as of October ___, 2000, between Medtronic, Inc., a
Minnesota corporation ("Grantee"), and PercuSurge, Inc., a Delaware corporation
("Issuer").

                                    RECITALS

     A. Grantee, Issuer, and Trojan Merger Corp., a Delaware corporation and
wholly-owned subsidiary of Grantee ("Merger Subsidiary"), have entered 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, par value $.001 per share ("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
Twelve Million Nine Hundred Twenty-Five Thousand Eight Hundred Sixty-Five
(12,925,865) shares of Issuer Common Stock (the "Option Shares"), in the manner
set forth below, at an exercise price of $4.32 per share of Issuer Common Stock,
subject to adjustment as provided below (the "Option Price"). Issuer represents
that the Option Shares represent 19.9% of the number of shares of Issuer Common
Stock (on a fully-diluted basis) 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 11), 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 8.2(a)(i) or Section 8.2(a)(ii) of the Merger Agreement or (ii)
     immediately prior to consummation of an Alternative Control Transaction
     after the occurrence of all of the events and circumstances specified in
     Section 8.2(a)(iii) of the Merger Agreement. This Option shall not be
     exercisable unless and until an Exercise Event shall occur.

                                       1
<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 specifying its intention to exercise the
     Option, 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 three
     nor more than ten 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"). 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 (the "Cash Cancellation Notice") 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 lesser of

               (x) the excess, if any, over the Option Price of the greater of
          (A) the highest price per share of Issuer Common Stock offered to be
          paid or paid in connection with the Alternative Transaction giving
          rise to such Cash Cancellation Notice, and (B) if the Alternative
          Transaction giving rise to such Cash Cancellation Notice is structured
          as an asset acquisition, the highest aggregate consideration offered
          to be paid or paid in such transaction or proposed transaction,
          divided by the number of shares of Issuer Common Stock then
          outstanding, and

               (y) $7,000,000 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 8.2(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,
         and the Cancellation Amount shall not exceed $7,000,000. 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, the amount described in clause (x)
         of the preceding sentence shall equal the excess, if any, over the
         Option Price of the Last Sale Price. In no event shall (i) the
         Cancellation Amount exceed $7,000,000 or (ii) the sum of the
         Termination Fee paid, the Option Share Profit not remitted to Issuer
         pursuant to Section 2(c) hereof, and the Cancellation Amount paid
         exceed $7,000,000.

               (c) In the event that Grantee sells, pledges, or otherwise
          disposes of (including, without limitation, by merger or exchange) any
          Option Shares (such sale or disposition of Option Shares within six
          months after acquisition referred to as a "Sale"), or in the event
          that any Cancellation Amount is paid to Grantee or any Option Share
          Profit is received by Grantee (and not required to be remitted to
          Issuer pursuant to this

                                       2
<PAGE>

          Section 2(c)), then any Termination Fee due and payable by Issuer
          shall be reduced to the extent necessary so that the sum of

                    (w) the Termination Fee;

                         (x) any Cancellation Amount 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 $7,000,000. Grantee shall remit to Issuer,
               within five business days after completion of any Sale, the
               amount, if any, by which the Option Share Profit from such Sale,
               when added to the Termination Fee previously paid, the
               Cancellation Amount previously paid, and the Option Share Profit
               from prior Sales of Option Shares not remitted to Issuer pursuant
               to this Section 2(c), exceeds $7,000,000.

     3. PAYMENT OF OPTION PRICE AND DELIVERY OF CERTIFICATE. Any Closings under
Section 2 of this Agreement 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 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.

     4. REGISTRATION OF OPTION SHARES. The Company shall use its commercially
reasonable best efforts to cause Grantee to be granted registration rights with
respect to the Option Shares pursuant to the certain Amended and Restated
Stockholder Rights Agreement dated March 17, 2000 among the Company and certain
shareholders of the Company.

     5. 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 requisite
corporate power and authority to enter into and perform this Agreement.

                                       3
<PAGE>


          (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 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
     limitations imposed by law on indemnification for liability under federal
     securities laws.

          (c) 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 10 hereof), each of
     which, upon issuance pursuant to this Agreement and when paid for as
     provided herein, will be validly 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.

          (d) 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 would not, individually or in the aggregate, reasonably be
     expected to have a Company Material Adverse Effect.

     6. 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 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

                                       4
<PAGE>

     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 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, including, without limitation,
     the 1933 Act.

          (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.

     7. COVENANTS OF GRANTEE. Grantee agrees not to transfer or otherwise
dispose of 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."

     8. REASONABLE BEST 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, reasonable best
efforts to obtain any necessary consents of third parties and governmental
agencies 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.

     9. CERTAIN CONDITIONS. The obligation of Issuer to issue Option Shares
under this Agreement upon 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;

                                       5
<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; and

          (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.

     10. 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.

     11. LIMITATION ON EXERCISE. Notwithstanding any other provision of this
Agreement, the Option may not be exercised for a number of Option Shares as
would, as of the date of the Exercise Notice, result in a Notional Total Profit
(as defined below) of more than $7,000,000 and, if exercise of the Option
otherwise would exceed such amount, Grantee, at its discretion, may increase the
Option Price for that number of Option Shares set forth in the Exercise Notice
so that the Notional Total Profit shall not exceed $7,000,000; provided, that
nothing in this sentence shall restrict any exercise of the Option permitted
hereby on any subsequent date at the Option Price set forth in Section 1.

     As used herein, "Notional Total Profit" with respect to any number of
Option Shares as to which Grantee may propose to exercise the Option means the
Total Profit determined as of the date of the Exercise Notice assuming, for
purposes of clause (iii) of the definition of Total Profit, that (x) the Option
were exercised on such date for such number of Option Shares and (y) such Option
Shares, together with all other Option Shares held by Grantee and its affiliates
as of such date, were sold for cash at the closing market price for Issuer
Common Stock as of the close of business on the preceding trading day (less
customary brokerage commissions).

     As used herein, "Total Profit" means the aggregate amount (before taxes) of
the following: (i) the Termination Fee paid to Grantee; (ii) any Cancellation
Amount paid to Grantee; and (iii) all Option Share Profits received in
connection with Sales of Option Shares and not remitted to Issuer pursuant to
Section 2(c).

     12. EXPIRATION. The Option shall expire at the earlier of (a) the Effective
Time (as defined in the Merger Agreement), (b) six months after the termination
of the Merger Agreement in accordance with the terms thereof in the event
Section 8.2(a)(i) or Section 8.2(a)(ii) of the Merger Agreement applies, or six
months after the date of consummation of the Alternative Control Transaction in
the event Section 8.2(a)(iii) of the Merger Agreement applies, or (c)
termination of the Merger Agreement in accordance with the terms thereof in
circumstances

                                       6
<PAGE>

under which the fee specified in Section 8.2 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 their reasonable best 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 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 any of its rights or
     obligations hereunder, other than Grantee's rights under Section 4 which
     may be assigned to a transferee of Option Shares.

          (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.

                                       7

          (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 given

                            NONCOMPETITION AGREEMENT

the Merger Agreement is terminated in accordance with Article 8 thereof.

     8. WAIVER, DISCHARGE, AMENDMENT, ETC. The failure of any party hereto to
enforce at any time any of the provisions of this Agreement shall in no way be
construed to be a waiver of any such provision, nor in any way to affect the

thereafter to enforce each and every such provision. No waiver of any breach of
this Agreement shall be held to be a waiver of any other or subsequent breach.
Any amendment to this Agreement shall be in writing and signed by the parties

to each Company Shareholder to whose Subaccount any Escrow Shares are credited
all notices of Parent shareholders' meetings, proxy statements and reports to
shareholders received by the Escrow Agent in respect thereof. The Escrow Agent
will either (i) vote the Escrow Shares credited to such Company Shareholder's
Subaccount in accordance with written instructions received from such Company
Shareholder, or (ii) forward to such Company Shareholder a signed proxy enabling
the Company Shareholder to vote such Escrow Shares. The Escrow Agent shall be
reimbursed for the cost of such forwarding in accordance with Section 6.4.

         2.5) DIVIDENDS, ETC. Any shares of Parent Common Stock or other equity
securities issued or distributed by Parent (including shares issued upon a stock

Fund shall be added to the Escrow Fund and become a part thereof and credited
proportionately to the Subaccounts to which the Escrow Shares are credited. New
Shares issued in respect of shares of Parent Common Stock which have been
released from the Escrow Fund shall not be added to the Escrow Fund but shall be
distributed to the recordholders thereof.

         2.6) TRANSFERABILITY. The interests of the Company Shareholders in the
Escrow Fund are an integral part of the consideration in the Merger, and shall

Company Shareholder to relative by blood, marriage or adoption (each a member of
a Company Shareholder's "Immediate Family") or to a

                                       4
<PAGE>


trust established by such Company Shareholder for the benefit of one or more
members of such Company Shareholder's Immediate Family shall be permitted;
provided, in each case, that the recipient of such shares of Parent Common
Stock shall receive and hold such shares subject to the provisions of this
Agreement and the Merger Agreement.

         2.7) FRACTIONAL ESCROW SHARES. Although each Company Shareholder's
Subaccount shall specify the number of Escrow Shares rounded to the nearest
thousandth of a share, no fractional shares of Parent Common Stock shall be
issued by Parent or released from the Escrow Account pursuant to this
Agreement. In connection with any release of Escrow Shares from the Escrow
Account, the Escrow Agent shall be permitted to "round down" or to follow
such other rounding procedures as the Escrow Agent reasonably determines to
be appropriate in order to avoid releasing any fractional shares from the
Escrow Account.

         2.8) TAXES. All dividends, distributions, interest and gains earned
or realized on the Escrow Fund ("Earnings") and credited to a Subaccount
shall be accounted for by the Escrow Agent separately from the Escrow Fund
and, notwithstanding any provisions of this Agreement, shall be treated as
having been received by the Company Shareholders to whose Subaccount the
Earnings are credited for tax purposes. The Escrow Agent annually shall file
information returns with the United States Internal Revenue Service and payee
statements with the Company Shareholders, documenting such Earnings. The
Company Shareholders shall provide to the Escrow Agent all forms and
information necessary to complete such information returns and payee
statements. In the event the Escrow Agent becomes liable for the payment of
taxes, including withholding taxes, relating to Earnings or any payment made
hereunder, the Escrow Agent may deduct such taxes from the Escrow Fund.

from the Shareholder Representatives to invest or reinvest the cash portion
of the Escrow Fund, the Escrow Agent agrees to invest and reinvest such funds
in Wells Fargo Bank Investment Money Market Mutual

                                       5

Fund, or a successor or similar fund agreed to by Parent and the Shareholder
Representatives in writing, which invests in direct obligations of, or
obligations fully guaranteed as to principal and interest by the United
States Government and repurchase agreements with respect to such securities.
Permitted Investments and interest accruing on, and any profit resulting
from, such investments shall be added to, and become a part of, the Escrow
Fund pursuant to this Escrow Agreement and shall be allocated among the
Subaccounts of the Company Shareholders based on the Permitted Investments
credited to the Subaccount of each. For purposes of this Escrow Agreement,
"interest" on the Escrow Fund shall include all proceeds thereof and
investment earnings with respect thereto. All Permitted Investments shall be
registered in the name of the Escrow Agent. The Escrow Agent shall have full
power and authority to sell any and all Permitted Investments held by it
under this Escrow Agreement as necessary to make disbursements under this
Escrow Agreement, and may use its bond department to effect such sales. The
Escrow Agent, Parent, the Surviving Corporation and the Shareholder
Representatives shall not be responsible for any unrealized profit or
realized loss realized on such investments.

         3.2) RELEASE OF ESCROW SHARES FOR SALE. Subject to Section 3.5, a
Company Shareholder may deliver to the Escrow Agent and to Parent a written
notice (a "Sale Notice") directing the Escrow Agent to deliver all (rounded
down to the nearest whole share) or a specified whole number of the Escrow
Shares (the "Sold Shares") credited to such Company Shareholder's Subaccount
to a broker or dealer for purposes of sale, against receipt by the Escrow
Agent of the proceeds of such sale, after deducting the commissions and other
charges of the broker or dealer effecting such sale (the "Sale Proceeds").
The Sale Notice shall state: (i) that a specified number of Escrow Shares
have been sold to or through the broker-dealer named therein, (ii) the sale
price per share and the aggregate Sale Proceeds, and (iii) the date of
payment for and delivery of the Sold Shares, which shall not be less than
five business days after delivery of the Sale Notice.

         3.3) SHORTAGE OF SALE PROCEEDS. If the Sale Proceeds, after
deducting the commissions and other charges of the broker or dealer effecting
such sale, as set forth in the Sale Notice, are less than 100% of the Current
Market Value of the Sold Shares as of the date of sale, the Escrow Agent
shall not deliver the Sold Shares unless it receives, in addition to the Sale
Proceeds, after deducting the commissions and other charges of the broker or
dealer effecting such sale, cash in an amount equal to the excess of 100% of
the Current Market Value of the Sold Shares as of the date of sale over such
Sale Proceeds.

         3.4) RETENTION OF SALE PROCEEDS. The Sale Proceeds and additional
cash, if any, received by the Escrow Agent in respect of Sold Shares shall be
retained in the Escrow Fund and credited to the Subaccount of the selling
Company Shareholder.

         3.5) RESTRICTIONS ON SALES. Escrow Shares allocated to the
Subaccounts of Company Shareholders who were, as the date of the Merger
Agreement, affiliates of the Company shall be subject to transfer
restrictions in connection with the accounting for the Merger as a pooling of
interests and under Rule 145 of the Securities Exchange Act of 1934. Such
Escrow Shares shall not be transferred pursuant to Section 3.2 except in
accordance with the Affiliate's Letter executed by the Company Shareholder
requesting such sale and in accordance with such Rule 145.

                          CLAIM PROCEDURES AND PAYMENTS

         4.1) CLAIM NOTICE. If Parent determines in good faith that a Parent
Indemnified Party is entitled to indemnification or reimbursement for Damages
under Article 9 of the Merger Agreement, then Parent may deliver to both the
Shareholder Representatives and the Escrow Agent a written notice of such
claim (a "Claim Notice") setting forth (i) a description in reasonable detail
(to the extent reasonably available to Parent) of the facts, circumstances or
events giving rise to the Damages based on Parent's good faith belief
thereof, including, without limitation, the identity and address of any
third-party claimant (to the extent reasonably available to Parent) and
copies of any formal demand or complaint and other related correspondence or
communications, and (ii) Parent's non-binding, preliminary, good faith
estimate of the reasonably foreseeable maximum amount of the alleged Damages
(which amount may be the amount of damages claimed by a third party plaintiff
in an action brought against Parent or the Company based on alleged facts,
which if true, would constitute a breach of the Company's representations and
warranties) (such aggregate amount being referred to as the "Claim Amount").
Such Claim Notice must be delivered on or before the termination of the
Survival Period. The Shareholder Representatives shall be entitled to control
the defense of such Third Party claims as provided in Section 9.5 of the
Merger Agreement.

         4.2) RESPONSE NOTICE. Within thirty (30) days after the delivery of
a Claim Notice to the Shareholder Representatives, the Shareholder
Representatives shall deliver to the Escrow Agent and Parent, a written
notice (the "Response Notice") containing: (i) instructions to the effect
that entire Claim Amount set forth in such Claim Notice is to be paid from
the Escrow Fund to Parent; or (ii) instructions to the effect that a
specified portion (but not the entire amount) of the Claim Amount set forth
in such Claim Notice is to paid from the Escrow Fund to Parent, together with
a statement that the remaining portion of such Claim Amount is being
disputed; or (iii) a statement that the entire Claim Amount set forth in such
Claim Notice is being disputed.

                  (a) If no Response Notice is received by the Escrow Agent and
         Parent from the Shareholder Representatives within thirty (30) days
         after the delivery of a Claim Notice to the Company Shareholders, then
         the Company Shareholders shall be deemed to have given instructions
         that the entire Claim Amount set forth in such Claim Notice shall be
         paid to Parent.

                  (b) If the Company Shareholders give (or are deemed to have
         given) instructions that the entire Claim Amount set forth in a Claim
         Notice may be paid from the Escrow Fund to Parent, then the Escrow
         Agent shall promptly, following the required delivery date for the
         Response Notice, transfer or pay to Parent the amount of such Claim
         from the Escrow Fund (or such lesser amount as is then held in the
         Escrow Fund).

                  (c) If a Response Notice delivered by the Shareholder
         Representatives in response to a Claim Notice contains instructions to
         the effect that a specified amount (but not the entire amount) of the
         Claim Amount set forth in such Claim Notice may be paid from the Escrow
         Fund to Parent, then (i) the Escrow Agent shall promptly, following the

                                       7
<PAGE>


         required delivery date for the Response Notice, pay to Parent such
         specified amount from the Escrow Fund, and (ii) the procedures set
         forth in Section 4.5 of this Agreement shall be followed with respect
         to the remaining portion of such Claim Amount.

                  (d) If a Response Notice delivered by the Shareholder
         Representatives in response to a Claim Notice contains a statement that
         all or a portion of the Claim Amount set forth in such Claim Notice is
         being disputed (such Claim Amount or the disputed portion thereof being
         referred to as the "Disputed Amount"), then such Disputed Amount shall
         not be paid until (i) delivery of a written notice executed by Parent
         and the Shareholder Representatives setting forth instructions to the
         Escrow Agent regarding the payment of such Disputed Amount, or (ii)
         delivery of a copy of a final and non-appealable judgment of a court
         setting forth instructions to the Escrow Agent as to the payment of
         such Disputed Amount. The Escrow Agent shall thereupon pay such
         Disputed Amount in accordance with the instructions set forth in such
         notice.

         4.3) PAYMENT OF CLAIMS. Payments, deliveries or designations from
the Escrow Fund made pursuant to any Claim Notice or as reimbursement for
expenses of the Shareholder Representatives as set forth in Section 7.2
hereof shall be made, on a Subaccount by Subaccount basis, first from Escrow
Shares, second from any cash, and third from any Permitted Investments. For
purposes of such payment, delivery or designation, Escrow Shares and
Permitted Investments shall be valued at their Current Market Value. To the
extent that any payment, delivery or designation is made pursuant to this
Escrow Agreement in the form of securities, such payment, delivery or
designation shall be rounded to the nearest whole number of such securities,
and no fractional securities shall be paid, delivered or designated.

         4.4) ALLOCATION AMONG SUBACCOUNTS. Payments and deliveries pursuant
to a Claim Notice or as reimbursement for expenses of the Shareholder
Representatives as set forth in Section 7.2 hereof shall be charged to and
withdrawn from each Subaccount in proportion to the respective Initial
Allocable Percentage of each, unless the Escrow Agent is restrained, enjoined
or stayed by law or court order from withdrawing assets from a Subaccount, in
which case the amount which would have been drawn from such Subaccount shall
be allocated pro rata among and withdrawn from the remaining Subaccounts as
to which the Escrow Agent is not so restrained, enjoined or stayed.

         4.5) DISPUTE RESOLUTION. In the event that any Response Notice
indicates that there is a Disputed Amount, the Shareholder Representatives
and Parent shall, for a period of sixty (60) days, attempt in good faith to
resolve the rights of the respective parties with respect to such Disputed
Amount. If the Shareholder Representatives and Parent should so agree, a
notice setting forth such agreement shall be signed by both Shareholder
Representatives and by Parent and sent to the Escrow Agent who shall
thereupon pay to Parent from the Escrow Fund such agreed upon amount (or such
lesser amount as is then held in the Escrow Fund).

                          RELEASE OF ESCROW ACCOUNT TO
                              COMPANY SHAREHOLDERS

         5.1) EXPIRATION OF SURVIVAL PERIOD. Promptly after the one-year
anniversary of the Effective Time, Escrow Agent shall disburse (or deliver to
the Exchange Agent for disbursement) to the Company Shareholders an aggregate
amount (the "Distribution Amount") equal to (A) the amount remaining in the
Escrow Fund, less (B) any Disputed Amount, and less (C) any Shareholder
Representatives' Expenses (to the extent the Escrow Agent has received
written notice from the Shareholder Representatives to such effect in
accordance with Section 7.2). The Escrow Agent shall, or Parent shall cause
the Exchange Agent to, disburse the Distribution Amount to the Company
Shareholders based on each Company Shareholder's respective Subaccount
balance. No certificates or scrip representing fractional shares of Parent
Common Stock or any other security shall be issued upon the disbursement of
the Distribution Amount. In lieu of any such fractional share, each Company
Shareholder who would otherwise have been entitled to a fraction of a share
of Parent Common Stock or other security upon disbursement of the
Distribution Amount will be paid an amount in cash (without interest),
rounded to the nearest cent, determined by multiplying (i) the Current Market
Value of such Parent Common Stock or such other securities (in the case of
such other securities, as of the Distribution Date) by (ii) the fractional
interest to which such holder would otherwise be entitled.

         5.2) REMAINING DISBURSEMENTS. Any amounts retained in the Escrow
Fund after the Distribution Date shall be held by the Escrow Agent and shall
first be used to indemnify the Parent Indemnified Parties, subject to the
terms and conditions of this Escrow Agreement, and upon resolution and
payment out of the Escrow Fund of all pending Claims, any remaining amounts
in escrow shall be transferred to the Shareholder Representatives with
respect to any remaining unpaid Shareholder Representatives' Expenses (to the
extent the Escrow Agent has received written notice from the Shareholder
Representatives to such effect in accordance with Section 7.2), and any
remaining amounts shall be disbursed in the manner set forth in Section 5.1.

                                   ARTICLE VI
                   LIABILITY AND COMPENSATION OF ESCROW AGENT

         6.1) NO IMPLIED DUTIES. The duties and obligations of the Escrow
Agent hereunder shall be determined solely by the express provisions of this
Escrow Agreement, and no implied duties or obligations shall be read into
this Escrow Agreement against the Escrow Agent. The Escrow Agent shall, in
determining its duties hereunder, be under no obligation to refer to any
other documents between or among the parties related in any way to this
Escrow Agreement (except to the extent that this Escrow Agreement
specifically refers to or incorporates by reference provisions of any other
document).

         6.2) INDEMNIFICATION OF ESCROW AGENT. Parent shall indemnify and
hold the Escrow Agent harmless from and against any and all liability and
expense which may arise out of any action taken or omitted by the Escrow
Agent in accordance with this Escrow Agreement, except such liability and
expense as may result from the gross negligence or willful misconduct of the
Escrow Agent. The reasonable costs and expenses, including reasonable
attorney fees, of the

                                       9
<PAGE>

Escrow Agent to enforce its indemnification rights under this Section 6.2
shall also be paid by Parent. Parent shall be entitled to be reimbursed out
of the Escrow Fund for fifty percent (50%) of any amount that Parent is
required to pay to the Escrow Agent pursuant to this Section 6.2, payable in
the manner set forth in Section 5.1 hereof. This right to indemnification
shall survive the termination of this Escrow Agreement and removal or
resignation of the Escrow Agent. With respect to any claims or actions
against the Escrow Agent which are indemnified by Parent under this Section
6.2, Parent shall have the right to retain sole control over the defense,
settlement, investigation and preparation related to such claims or actions;
provided that (i) the Escrow Agent may employ its own counsel to defend such
a claim or action if it reasonably concludes, based on the advice of counsel,
that there are defenses available to it which are different from or
additional to those available to Parent and (ii) neither Parent nor the
Escrow Agent shall settle or compromise any such claim or action without the
consent of the other, which consent shall not be unreasonably withheld or
delayed.

         6.3) STANDARD OF CARE; RELIANCE. The Escrow Agent shall not be liable
to any person by reason of any error of judgment or for any act done or step
taken or omitted by it, or for any mistake of fact or law or anything which it
may do or refrain from doing in connection herewith unless caused by or arising
out of its own gross negligence or willful misconduct. The Escrow Agent shall be
entitled to rely on, and shall be protected in acting in reliance upon, any
instructions or directions furnished to it in writing signed by both Parent and
all the then Shareholder Representatives pursuant to any provision of this
Escrow Agreement and shall be entitled to treat as genuine, and as the document
it purports to be, any letter, paper or other document furnished to it by any
Parent Indemnified Party or the Shareholder Representatives, and believed by the
Escrow Agent to be genuine and to have been signed and presented by the proper
party or parties. In performing its obligations hereunder, the Escrow Agent may
consult with counsel to the Escrow Agent and shall be entitled to rely on, and
shall be protected in acting in reliance upon, the advice or opinion of such
counsel.

         6.4) COMPENSATION OF ESCROW AGENT. The Escrow Agent shall be entitled
to its customary fee for the performance of services by the Escrow Agent
hereunder for each year or portion thereof that any portion of the Escrow Fund
remains in escrow and shall be reimbursed for reasonable costs and expenses
incurred by it in connection with the performance of such services (such fees,
costs and expenses are hereinafter referred to as the "Escrow Agent's
Compensation"). A schedule of the Escrow Agent's fees is attached hereto as
Exhibit ____. The Escrow Agent shall render statements to Parent setting forth
in detail the Escrow Agent's Compensation and the basis upon which the Escrow
Agent's Compensation was computed. The Escrow Agent's Compensation shall be paid
by Parent. To the extent the Escrow Agent's Compensation is not paid by Parent,
the foregoing shall be paid from the Escrow Fund after written notice from the
Escrow Agent to Parent. Parent shall be entitled to be reimbursed out of the
Escrow Fund for fifty percent (50%) of any amount that Parent is required to pay
to the Escrow Agent pursuant to such reimbursement obligation, payable in the
manner set forth in Section 5.1 hereof.

         6.5) RESIGNATION AND SUCCESSOR. The Escrow Agent may resign at any
time by giving sixty (60) days written notice to Parent and the Shareholder
Representatives; provided that such resignation shall not be effective unless
and until a successor Escrow Agent has been appointed and accepts such
position pursuant to the terms of this Section 6.5. In such event, Parent and
the

                                       10
<PAGE>

Shareholder Representatives shall appoint a successor Escrow Agent or, if
Parent and the Shareholder Representatives are unable to agree upon a
successor Escrow Agent within sixty (60) days after such notice, the Escrow
Agent shall be entitled to (i) appoint its own successor, provided that such
successor is a reputable national banking association or (ii) at the equal
expense of Parent and the Shareholder Representatives, petition any court of
competent jurisdiction for the appointment of a successor Escrow Agent. Such
appointment, whether by Parent and the Shareholder Representatives, on the
one hand, or the Escrow Agent, on the other hand, shall be effective on the
effective date of the aforesaid resignation (the "Escrow Transfer Date"). On
the Escrow Transfer Date, all right title and interest to the Escrow Fund,
including interest thereon, shall be transferred to the successor Escrow
Agent and this Escrow Agreement shall be assigned by the Escrow Agent to such
successor Escrow Agent, and thereafter, the resigning Escrow Agent shall be
released from any further obligations hereunder. The Escrow Agent shall
continue to serve until its successor is appointed, accepts the Escrow and
receives the transferred Escrow Fund.

         6.6) DISPUTES. It is understood and agreed that in the event any
disagreement among Parent and the Shareholder Representatives results in
adverse claims or demands being made in connection with the Escrow Fund, or
in the event the Escrow Agent in good faith is in doubt as to what action it
should take hereunder, the Escrow Agent shall retain the Escrow Fund until
the Escrow Agent shall have received (i) an enforceable final order of a
court of competent jurisdiction which is not subject to further appeal
directing delivery of the Escrow Fund or (ii) a written agreement executed by
Parent and the Shareholder Representatives directing delivery of the Escrow
Fund, in which event Escrow Agent shall disburse the Escrow Fund in
accordance with such order or agreement. Any court order referred to in
clause (i) immediately above shall be accompanied by a legal opinion of
counsel for the presenting party satisfactory to the Escrow Agent to the
effect that said court order or judgment is final and enforceable and is not
subject to further appeal. The Escrow Agent shall act on such court order and
legal opinion without further question.

         6.7) LIMITATION ON DAMAGES. In no event shall the Escrow Agent be
liable in connection with this Escrow Agreement for any special, indirect or
consequential loss or damage of any kind whatsoever, even if the Escrow Agent
has been previously advised of such loss or damage.


                                   ARTICLE VII
                           SHAREHOLDER REPRESENTATIVES

         7.1) APPOINTMENT. Pursuant to the Merger Agreement, the Shareholder
Representatives shall jointly act as agent and attorney-in-fact for the
Company Shareholders and are entitled to give and receive notices and
communications, to authorize delivery to the Parent Indemnified Parties of
the Parent Common Stock or other property from the Escrow Fund in
satisfaction of claims by the Parent Indemnified Parties, to object to such
deliveries in accordance with the terms of this Escrow Agreement, to agree
to, negotiate, enter into settlements and compromises of, and demand
arbitration and comply with orders of courts and awards of arbitrators with
respect to such claims, to retain legal counsel, accountants, expert
witnesses, consultants and other third parties (collectively, "Outside
Parties") to assist the Shareholder Representatives with their duties under
the Merger Agreement and hereunder, and to

                                       11
<PAGE>

take all actions necessary or appropriate in the judgment of the Shareholder
Representatives for the accomplishment of the foregoing. All actions of the
Shareholder Representatives shall be in writing signed by both of the
above-named individuals, or their successors, acting in their capacity as
Shareholder Representatives. The persons designated to be the Shareholder
Representatives may be changed in accordance with the provisions set forth in
Section 10.12 of the Merger Agreement.

         7.2) EXPENSES. At any time or from time to time prior to the final
distribution of all Escrow Shares out of Escrow, the Shareholder Representatives
may deliver notice to the Escrow Agent and Parent setting forth the amount of
the out-of-pocket expenses incurred by the Shareholder Representatives in
connection with their duties under the Merger Agreement and hereunder,
including, but not limited to the fees and expenses of Outside Parties, plus an
hourly rate of $250 per hour for time spent by the Shareholder Representatives
in excess of 6 hours per month per Shareholder Representative in rendering
services under the Merger Agreement and hereunder (the "Shareholder
Representatives' Expenses"), which expenses shall be reimbursed from the Escrow
Fund promptly after receipt of each such notice.

         7.3) AUTHORITY AND RELIANCE. Neither Parent, any Parent Indemnified
Party, the Company, nor the Escrow Agent shall be responsible or liable for any
acts or omissions of the Shareholder Representatives in such Shareholder
Representatives' capacity as such. A decision, act, consent or instruction of
the Shareholder Representatives shall constitute a decision of all Company
Shareholders for whom shares of Parent Common Stock otherwise issuable to them
are deposited in the Escrow Fund and shall be final, binding and conclusive upon
each such Company Shareholder, and the Escrow Agent and Parent may rely upon any
decision, act, consent or instruction of the Shareholder Representatives as
being the decision, act, consent or instruction of each and every such Company
Shareholder. The Escrow Agent and each Parent Indemnified Party are hereby
relieved from any liability to any person for any acts done by them in
accordance with such decision, act, consent or instruction of the Shareholder
Representatives. For purposes of this Escrow Agreement any action by all of the
then Shareholder Representatives shall be deemed to be the action of and binding
upon all of the Shareholder Representatives.

terminated prior to the Effective Time on the occurrence of either the following

                                     GENERAL

         10.1) OTHER AGREEMENTS. Nothing in this Agreement is intended to
limit any of the Company's, Parent's or the Company Shareholders' rights, or

         10.4) SEVERABILITY. If any provision of this Agreement, or the
application of such a provision, is for any reason and to any extent invalid
or unenforceable, the remainder of this Agreement and application of such
provision to other circumstances shall be interpreted so as reasonably to

counterparts, each of which shall be deemed to be an original and all of
which shall constitute one and the same instrument. This Agreement shall

terms of this Agreement, no such amendment or waiver shall require the
consent of such third party to be effective. The waiver by a party of any
breach of this Agreement or default in the performance of any obligations

interpret any part of this Agreement, the prevailing party shall be entitled
to recover, as an element of the costs of suit and not as damages, reasonable
attorneys' fees to be fixed by the court (including, without limitation,
costs, expenses and fees on any appeal), provided that Parent's sole recourse
for such attorneys fees under the Merger Agreement and hereunder against the
Company Shareholders or the Shareholder Representatives acting as their
representatives shall be against the Escrow Shares. The prevailing party
shall be entitled to recover such party's costs of suit, regardless of
whether such suit proceeds to final judgment.

Medtronic, Inc.
Corporate Center
7000 Central Avenue, N.E.
Minneapolis, MN  55432


Ladies and Gentlemen:

     We have acted as counsel to PercuSurge, Inc., a Delaware corporation
("PercuSurge" or the "Company"), in connection with the merger (the "Merger") of
Trojan Merger Corp., a Delaware corporation ("Merger Subsidiary") and
wholly-owned subsidiary of Medtronic, Inc. ("Medtronic" or "Parent"), with and
into PercuSurge pursuant to the Agreement and Plan of Merger among PercuSurge,
Merger Subsidiary and Medtronic dated as of October __, 2000 (the "Merger
Agreement"), and the related Stock Option Agreement, Affiliate's Letters,
Agreements to Facilitate Merger, Escrow Agreement and other documents and
instruments being entered into in connection with the Merger to which PercuSurge
is a party, as applicable (collectively, the "Ancillary Agreements"). This
opinion is furnished to you pursuant to Section 7.2(h) of the Merger Agreement.
Unless otherwise defined herein, the capitalized terms used in this opinion have
the meaning given to them in the Merger Agreement.

     As counsel for the Company, we have made such legal and factual
examinations and inquiries as we have deemed advisable or necessary for the
purpose of rendering this opinion. In addition, we have examined originals or
copies of such corporate records of the Company, certificates of public
officials and such other documents which we consider necessary or advisable for
the purpose of rendering this opinion. In such examination we have assumed the
genuineness of all signatures on original documents, the authenticity and
completeness of all documents submitted to us as originals, the conformity to
original documents of all copies submitted to us and the due execution and
delivery of all documents (except as to due execution and delivery by the
Company) where due execution and delivery are a prerequisite to the
effectiveness thereof.

     As used in this opinion, the expression "to our knowledge," "known to us"
or similar language with reference to matters of fact means that, after an
examination of documents made available to us by the Company, and after
inquiries of officers of the Company, but without any

<PAGE>

further independent factual investigation, we find no reason to believe that the
opinions expressed herein are factually incorrect. Further, the expression "to
our knowledge," "known to us" or similar language with reference to matters of
fact refers to the current actual knowledge of the attorneys of this firm who
have worked on matters for the Company. Except to the extent expressly set forth
herein or as we otherwise believe to be necessary to our opinion, we have not
undertaken any independent investigation to determine the existence or absence
of any fact, and no inference as to our knowledge of the existence or absence of
any fact should be drawn from our representation of the Company or the rendering
of the opinion set forth below.

     For purposes of this opinion, we are assuming that you have all requisite
power and authority, and have taken any and all necessary corporate or
partnership action, to execute and deliver the Merger Agreement, and we are
assuming that the representations and warranties made by Parent in the Merger
Agreement and pursuant thereto are true and correct.

     The opinions hereinafter expressed are subject to the following
qualifications:

          (a) We express no opinion as to the effect of applicable bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance or other similar
federal or state laws affecting the rights of creditors;

          (b) We express no opinion as to the effect of general principles of
equity, including, without limitation, concepts of materiality, reasonableness,
good faith and fair dealing;

          (c) We express no opinion as to the effect of rules of law governing
specific performance, injunctive relief or other equitable remedies (regardless
of whether any such remedy is considered in a proceeding at law or in equity);

          (d) We express no opinion as to the effect of patent, trademark or
copyright laws;

          (e) We express no opinion as to compliance with the anti-fraud
provisions of applicable securities laws;

          (f) We express no opinion as to the effect, if any, of federal and
state laws and regulations dealing with antitrust and unfair competition matters
and filing and notice requirements (including, but not limited to, the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended);

          (g) We express no opinion as to the enforceability of the
indemnification provisions contained in the Merger Agreement to the extent the
provisions thereof may be subject to limitations of public policy and the effect
of applicable statutes and judicial decisions;

<PAGE>

          (h) We are members of the Bar of the State of California and we
express no opinion as to any matter relating to the laws of any jurisdiction
other than the federal laws of the United States of America, the laws of the
State of California, and the general corporate laws of the State of Delaware. To
the extent this opinion addresses applicable securities laws of states other
than the State of California, we have not retained nor relied on the opinion of
counsel admitted to the bar of such states, but rather have relied on
compilations of the securities laws of such states contained in reporting
services presently available to us.

     With respect to our opinion in paragraph 6 below regarding the number of
shares of PercuSurge capital stock outstanding and the due authorization and
valid issuance of all outstanding shares, and the fully paid and non-assessable
nature of all outstanding shares, of capital stock, and options and warrants
exercisable for shares of capital stock, as well as the conversion rate and
applicable "Conversion Price" of each series of Preferred Stock, of PercuSurge,
we have examined and relied solely upon an examination of the minutes of the
Company's Board of Directors and committees thereof, stock books and stock
option records supplied to us by PercuSurge and upon representations in the
Officer's Certificate addressed to us by PercuSurge of even date herewith a copy
of which has been provided to you, and we have undertaken no other verification
with respect thereto.

     Except as otherwise indicated, all opinions herein are rendered as of the
time immediately preceding the Effective Time. We do not undertake to advise you
of changes in the law, facts, or circumstances that may hereafter occur.

     Based upon and subject to the foregoing, we are of the opinion that:

     1. PercuSurge 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 to own, lease and operate its properties and to carry on its business as
presently conducted.

     2. PercuSurge has full corporate power and authority to enter into the
Merger Agreement, Stock Option Agreement, Affiliate's Letters, and Escrow
Agreement, and to consummate the transactions contemplated thereby. The
execution, delivery and performance by PercuSurge of the Merger Agreement, Stock
Option Agreement, Affiliate's Letters, and Escrow Agreement, and the
consummation by PercuSurge of the transactions contemplated thereby have been
duly authorized by the Board of Directors and stockholders of PercuSurge, and no
other corporate action on the part of PercuSurge is necessary to authorize the
execution, delivery and performance by PercuSurge of the Merger Agreement, Stock
Option Agreement, Affiliate's Letters, and Escrow Agreement, and the
consummation by PercuSurge of the transactions contemplated thereby.

<PAGE>

     3. The Merger Agreement, Stock Option Agreement, Affiliate's Letters, and
Escrow Agreement have been duly executed and delivered by PercuSurge, and
assuming due authorization, execution and delivery by the other parties to such
agreements, constitute valid and binding obligations of PercuSurge, enforceable
against PercuSurge in accordance with their respective terms.

     4. Except as disclosed in the Merger Agreement or the Company Disclosure
Schedule, the execution, delivery and performance by PercuSurge of the Merger
Agreement and the Stock Option Agreement, the compliance by PercuSurge with the
provisions thereof, and the consummation by PercuSurge of the transactions
contemplated thereby, will not: (i) violate any provision of the Certificate of
Incorporation or Bylaws of PercuSurge or any Subsidiary; (ii) violate any
governmental statute, rule, or regulation applicable to the Company which a
lawyer in the State of California exercising customary diligence would
reasonably recognize as applicable to transactions of the type contemplated by
the Merger Agreement (without our having made any investigation concerning the
applicability of any other law) or (iii) result in any material violation or
breach of, or constitute a default under, or give rise to any right of
termination, cancellation, or acceleration under, or result in the creation of
any material Lien on any of the properties or assets of PercuSurge or any
Subsidiary under, any of the terms, conditions or provisions of any contract,
indenture, mortgage, lease, loan, or other agreement to which PercuSurge or any
Subsidiary is a party which is listed in the Company Disclosure Schedule.

     5. Except as set forth in the Merger Agreement or the Company Disclosure
Schedule and except for (a) filing and recordation of the Certificate of Merger
with the Secretary of State of Delaware; (b) such consents, approvals, permits,
registrations and filings as may be required under applicable federal and state
securities laws; and (c) such other consents, approvals, permits, registrations
and filings, which, if not made, would not prevent or materially alter or delay
any of the transactions contemplated by the Merger Agreement, no consent,
approval, permit, registration, or filing with any federal or state governmental
authority is required by, or with respect to, the Company in connection with the
execution and delivery of the Merger Agreement, Stock Option Agreement,
Affiliate's Letters or Escrow Agreement, or the consummation of the transactions
contemplated thereby.

     6. PercuSurge has duly authorized capital stock consisting solely of (i)
50,000,000 shares of PercuSurge Common Stock, par value $.001 per share, of
which _________ shares are issued and outstanding and no shares are held in the
PercuSurge's treasury, and (ii) 41,569,957 shares of PercuSurge Preferred Stock,
par value $.001 per share, of which: (A) 8,352,642 shares are designated Series
A Preferred Stock and ____ of which are issued and outstanding; (B) 9,428,296
shares are designated Series B Preferred Stock and ____ of which are issued and
outstanding; (C) 4,334,211 shares are designated Series C Preferred Stock and
___ of which are issued and outstanding; (D) 11,219,513 shares are designated
Series D Preferred Stock and ___ of which are issued and outstanding; and (E)
8,235,295 shares are designated Series E Preferred

<PAGE>

Stock and ___ of which are issued and outstanding. To our knowledge each share
of outstanding PercuSurge Preferred Stock is convertible into one share of
PercuSurge Common Stock, and the respective "Conversion Price" of each series of
PercuSurge Preferred Stock has not been adjusted pursuant to Section 3(e) of
PercuSurge's Certificate of Incorporation. To our knowledge all issued and
outstanding shares of capital stock of each Subsidiary are owned, beneficially
and of record, by PercuSurge. All issued and outstanding shares of PercuSurge
Common Stock and PercuSurge Preferred Stock have been validly issued, and are
(assuming receipt by PercuSurge of the consideration therefor recited in the
PercuSurge Board of Directors minutes with respect to such issuance) fully paid
and nonassessable. Except for options to purchase an aggregate _______ shares of
PercuSurge Common Stock granted pursuant to the PercuSurge's 1995 Stock Option
Plan (the "PercuSurge Option Plan") or otherwise and warrants to purchase an
aggregate _____ shares of PercuSurge Preferred Stock, to our knowledge there are
not any outstanding subscriptions, options, warrants, calls, rights, convertible
securities, or any other agreements to which PercuSurge is a party that,
directly or indirectly, obligate PercuSurge 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.

     This opinion is intended solely for your use in connection with
transactions contemplated by the Agreement, and may not be relied upon by any
other persons or entities or for any other purpose without our prior written
consent.


                                       Very truly yours,

Ladies and Gentlemen:

     We have acted as counsel to Medtronic, Inc., a Minnesota corporation
("Medtronic"), and its wholly-owned subsidiary, Trojan Merger Corp., a Delaware
corporation ("Merger Subsidiary"), in connection with the preparation of the
Agreement and Plan of Merger dated October ___, 2000 (the "Merger Agreement"),
among Medtronic, Merger Subsidiary, and PercuSurge, Inc. a Delaware corporation
("PercuSurge"), and the preparation of the related Affiliate's Letters and
Escrow Agreement contemplated thereby (the "Ancillary Agreements"). This opinion
is given pursuant to Section 7.3(e) of the Merger Agreement. Capitalized terms
used herein without definition have the same meaning as in the Merger Agreement.

     As to various matters of fact material to this opinion, we have relied upon
certificates of public officials and upon the representations of Medtronic or
its officers or directors, including those made in the Merger Agreement and in
documents or certificates executed in connection therewith. We have also
examined the Articles or Certificate of Incorporation and Bylaws of each of
Medtronic and Merger Subsidiary, each as amended to date as presented to us by
Medtronic, and originals or copies of such other corporate documents and records
and other certificates and instruments and have made such other investigation as
we have deemed necessary in connection with the opinions hereafter set forth. We
have not independently or through third parties verified such certificates,
representations, or statements or made any independent investigation as to the
existence of agreements, instruments, corporate records, or other documents,
orders, judgments, or decrees by which Medtronic or any of its properties may be
bound.

     We have examined the laws of the State of Minnesota, the Delaware General
Corporation Law, and federal laws of the United States as we have deemed
relevant for the purpose of this opinion, but we have not made an independent
review of the laws of any other state or jurisdiction. We are members of the bar
of the State of Minnesota and, accordingly, our opinions are limited solely to
the laws of the United States, the Delaware General Corporation Law, and the
State of Minnesota (including, without limitation, laws dealing with choice or
conflict of laws), and we express no opinion concerning the laws of any other
jurisdiction. To the extent that the laws of other jurisdictions may govern the
Merger Agreement or any agreements or instruments related thereto or any other
matters as to which we express an opinion herein, we have assumed without any
independent investigation whatsoever that such laws are the same as those of the
State of Minnesota; to the extent that the laws of such other jurisdictions
differ from

those of the State of Minnesota with respect to any matters contained in this
opinion, our opinion as to such matters is thereby limited to Minnesota law
without regard to the parties' choice of law.

     For purposes of this opinion, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals, the
conformity to original documents of all documents submitted to us as copies, and
that the information in the certificates, representations, and statements
referred to above remains true and complete as of the date hereof. In examining
documents executed by parties other than Medtronic or Merger Subsidiary, we have
assumed that such parties have all necessary power to enter into and perform all
of their obligations thereunder and that such parties have duly executed and
delivered such documents. We have also assumed, as to each such party, the due
authorization by all requisite action of the execution, delivery and performance
of such documents by such parties and that such documents are legal, valid,
binding on and enforceable against such parties in accordance with their
respective terms. We have also assumed that each natural person executing any of
the documents and agreements involved in the matters covered by this opinion has
the capacity and is legally competent to do so.

     References in this opinion to "our knowledge," "known to us," or the like
mean that in the course of our representation of Medtronic no information has
come to the attention of any attorney within the firm who has given substantive
attention to Medtronic's legal matters within the last 12 months that gives such
attorney actual knowledge that such opinion is not accurate.

     Based upon and subject to the foregoing, and subject to the qualifications
hereinafter set forth, it is our opinion as of this date that:

     1. Each of Medtronic and Merger Subsidiary is a corporation duly organized,
validly existing and in good standing under the laws of its respective
jurisdiction of incorporation and has all requisite corporate power to own,
lease and operate its properties and to carry on its business as presently
conducted.

     2. Each of Medtronic and Merger Subsidiary has the requisite corporate
power to execute, deliver, and perform the Merger Agreement and the Ancillary
Agreements to which it is a party, and to consummate the transactions
contemplated thereby.

     3. The execution, delivery and performance by Medtronic and Merger
Subsidiary of the Merger Agreement and the Ancillary Agreements to which it is a
party, and the consummation by them of the transactions contemplated thereby
(including the issuance of the shares of Common Stock of Medtronic to the
shareholders of PercuSurge pursuant to the Merger) have been duly authorized by
the Board of Directors of Medtronic and the shareholder and the Board of
Directors of Merger Subsidiary, and no other corporate action on the part of
Medtronic or Merger Subsidiary is necessary to authorize the execution, delivery
and

performance by Medtronic and Merger Subsidiary of the Merger Agreement and the
Ancillary Agreements to which it is a party, and the consummation by them of the
transactions contemplated thereby (including the issuance of the shares of
Common Stock of Medtronic to the shareholders of PercuSurge pursuant to the
Merger).

     4. The Merger Agreement and the Ancillary Agreements to which they are a
party has been duly and validly executed and delivered by Medtronic and Merger
Subsidiary and constitutes a valid and binding obligation of them, enforceable
in accordance with its terms.

     5. Except as specifically disclosed in Section 5.4 of the Merger Agreement
or in the Parent Disclosure Schedule, the execution, delivery and performance by
Medtronic and Merger Subsidiary of the Merger Agreement and the Ancillary
Agreements to which they are a party, the compliance by them with the provisions
thereof, and the consummation by them of the transactions contemplated thereby
will not: (i) violate any provision of the Articles or Certificate of
Incorporation or Bylaws of Medtronic or Merger Subsidiary; (ii) violate any
governmental statute, rule, regulation applicable to Medtronic or Merger
Subsidiary which a lawyer in the State of Minnesota exercising customary
diligence would reasonably recognize as applicable to transactions of the type
contemplated by the Merger Agreement (without our having made any investigation
concerning the applicability of any other law); or (iii) to our knowledge,
result in any violation or breach of, or constitute a default 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 Medtronic or Merger Subsidiary under, any of the terms,
conditions, or provisions of any contract, indenture, mortgage, lease, loan, or
other agreement to which Medtronic or Merger Subsidiary is a party filed with
(or incorporated by reference into) the Registration Statement as a "material
contract" pursuant to Item 601 of Regulation S-K.

     6. Except as set forth in the Merger Agreement or the Parent Disclosure
Schedule and except for (a) filing and recordation of the Certificate of Merger
with the Secretary of State of Delaware; (b) such consents, approvals, permits,
registrations and filings as may be required under applicable federal and state
securities laws; and (c) such other consents, approvals, permits, registrations
and filings, which, if not made, would not prevent or materially alter or delay
any of the transactions contemplated by the Merger Agreement, no consent,
approval, permit, registration, or filing with any federal or state governmental
authority is required by, or with respect to, Medtronic or Merger Subsidiary in
connection with the execution and delivery of the Merger Agreement and the
Ancillary Agreements to which they are a party, or the consummation of the
transactions contemplated thereby.

     7. The shares of Common Stock of Medtronic to be issued to the shareholders
of PercuSurge in the Merger will be duly and validly issued and, subject to the
Escrow Agreement, fully paid and non-assessable.

     In addition to the qualifications set forth above with respect to the
opinions expressed herein, all of our opinions expressed herein are subject to
the following additional qualifications:

     A. The opinions expressed above are qualified to the extent that the
validity or enforceability of any provisions of the Merger Agreement or any
related agreement, document, or instrument or of any rights granted to
PercuSurge or any other party pursuant to the Merger Agreement or any related
agreement, document, or instrument may be subject to or affected or limited by
(i) applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent or
preferential transfer or conveyance, equitable subordination, or similar laws or
decisions relating to or affecting the rights of creditors generally, (ii)
general principles of equity, including (without limitation) concepts of
materiality, reasonableness, good faith, and fair dealing, and the rules of law
governing, and discretion of a court (at law or in equity) in granting, specific
performance, injunctive relief, or any equitable or other particular remedy, and
(iii) our assumption that there exist no other agreements (other than the Merger
Agreement or other agreements or instruments specifically referred to therein),
understandings, or negotiations among the parties to the Merger Agreement that
would modify the terms of the Merger Agreement, the Ancillary Agreements, or any
related documents or instruments or the respective rights or obligations of the
parties thereunder.

     B. The opinions expressed above are further subject to limitations arising
from state and federal court decisions involving statutes, public policy, or

statutory provisions or common law rights and broadly or vaguely stated
provisions waiving rights or waivers of unknown future rights or duties imposed
by law are or may be unenforceable, and (ii) under certain circumstances,
provisions declaring that the failure to exercise or delay in exercising rights
or remedies will not operate as a waiver of any such right or remedy are
invalid.

or effect of, any state or federal antitrust laws, rules, or regulations.

     D. This opinion is limited to the present laws of the State of Minnesota,
the Delaware General Corporation Law and the federal laws of the United States
of America, to present judicial interpretation thereof, and to the facts as they
presently exist. In rendering this opinion, we assume no obligation to revise or
supplement this opinion if the present laws of any jurisdiction mentioned above
are changed by legislative action, judicial decision, or otherwise; if the facts
as they presently exist change; or if matters not presently known to us
hereafter come to our attention.
