Dear Shareholder: 

You are cordially invited to attend a Special Meeting of Shareholders (the 
"Special Meeting") of Daig Corporation ("Daig") to be held on May 30, 1996, 
at 9:00 a.m., local time, at The Kelly Inn, 2705 Annapolis Lane, Plymouth, 
Minnesota 55441, 

At the Special Meeting, you will be asked to consider and vote on a proposal 
to approve an Agreement and Plan of Merger (the "Merger Agreement") pursuant 
to which a wholly owned subsidiary of St. Jude Medical, Inc. ("SJM") will be 
merged with and into Daig (the "Merger"). Daig will be the surviving 
corporation and a wholly owned subsidiary of SJM. The terms of the Merger 
Agreement provide that holders of the common stock, par value $.01 per share, 
of Daig ("Daig Common Stock") will receive, for each share of Daig Common 
Stock owned immediately prior to the effective time of the Merger, .651733 of 
a share (the "Conversion Ratio") of the common stock, par value $.10 per 
share, of SJM ("SJM Common Stock") together with cash in lieu of any 
fractional share of SJM Common Stock to which such holder would otherwise be 
entitled. 

THE BOARD OF DIRECTORS OF DAIG BELIEVES THAT THE MERGER IS IN THE BEST 
INTERESTS OF DAIG AND ITS SHAREHOLDERS AND THEREFORE UNANIMOUSLY RECOMMENDS 
THAT YOU VOTE IN FAVOR OF APPROVAL OF THE MERGER AGREEMENT. The Board of 
Directors of Daig has received a written opinion from its financial advisor, 
Goldman, Sachs & Co., that, as of the date of the Merger Agreement, the 
Conversion Ratio pursuant to the Merger Agreement is fair to the shareholders 
of Daig. A copy of this opinion is included as Exhibit C to the Proxy 
Statement/Prospectus. 

I urge you to review carefully the accompanying Notice of Special Meeting of 
Shareholders, Proxy Statement/Prospectus and Proxy, which contain information 
about Daig and SJM and describe the proposed Merger and certain related 
matters. 

All shareholders are invited to attend the Special Meeting in person. The 
affirmative vote of the holders of not less than a majority of the 
outstanding shares of Daig Common Stock entitled to vote at the Special 
Meeting will be necessary for approval of the Merger Agreement. 

If the Merger Agreement is approved and the Merger is consummated, you will 
be sent a letter of transmittal with instructions for surrendering your 
certificates representing shares of Daig Common Stock. PLEASE DO NOT SEND 
YOUR SHARE CERTIFICATES UNTIL YOU RECEIVE THESE MATERIALS. 

In order that your shares may be represented at the Special Meeting, you are 
urged to complete, sign, date and return promptly the accompanying Proxy in 
the enclosed envelope, whether or not you plan to attend the Special Meeting. 
If you attend the Special Meeting in person, you may, if you wish, vote 
personally on the matter brought before the Special Meeting even if you have 
previously returned your Proxy. Your prompt cooperation will be appreciated. 

Sincerely, 
John J. Fleischhacker 
CHAIRMAN OF THE BOARD 
AND CHIEF EXECUTIVE OFFICER 

                               DAIG CORPORATION

                  NOTICE OF SPECIAL MEETING OF SHAREHOLDERS 
                           TO BE HELD MAY 30, 1996 

To the Shareholders of Daig Corporation: 

NOTICE IS HEREBY GIVEN that a Special Meeting of Shareholders (the "Special 
Meeting") of Daig Corporation, a Minnesota corporation ("Daig") will be held 
on May 30, 1996, at 9:00 a.m., local time, at The Kelly Inn, 2705 Annapolis 
Lane, Plymouth, Minnesota 55441, for the following purpose: 

1. To consider and vote upon a proposal to approve an Agreement and Plan of 
   Merger, dated as of January 29, 1996 (the "Merger Agreement"), by and 
   among St. Jude Medical, Inc., a Minnesota corporation ("SJM"), Partner 
   Acquisition Corp., a Minnesota corporation and a wholly owned subsidiary 
   of SJM ("Merger Subsidiary"), and Daig. Pursuant to the Merger Agreement, 
   among other things, (a) Merger Subsidiary will be merged with and into 
   Daig, with Daig to be the surviving corporation and a wholly owned 
   subsidiary of SJM (the "Merger"), and (b) each outstanding share of common 
   stock, par value $.01 per share, of Daig ("Daig Common Stock") (other than 
   shares of Daig Common Stock as to which dissenters' rights have been 
   perfected under the Minnesota Business Corporation Act (the "MBCA")), will 
   be converted into the right to receive .651733 of a share of common stock, 
   par value $.10 per share, of SJM ("SJM Common Stock") together with cash 
   in lieu of any fractional share of SJM Common Stock to which a holder of 
   Daig Common Stock would otherwise be entitled (after aggregating all 
   fractional shares of SJM Common Stock to be received by such holder). 

The Board of Directors of Daig has fixed the close of business on April 26, 
1996, as the record date for the determination of shareholders entitled to 
notice of and to vote at the Special Meeting, and only shareholders of record 
at such time will be entitled to notice of, and to vote at, the Special 
Meeting. 

Please be advised that, if the proposed Merger is approved and consummated, 
holders of Daig Common Stock who file a written notice of dissent before the 
vote and who do not vote for the Merger will have the right to dissent from 
the proposed Merger and to receive the "fair value" of their shares of Daig 
Common Stock in cash, if they fully comply with Sections 302A.471 and 
302A.473 of the MBCA. A summary of the rights of holders of Daig Common Stock 
and copies of the aforementioned Sections of the MBCA are included in the 
accompanying Proxy Statement/Prospectus. SEE "DISSENTING SHAREHOLDERS' 
RIGHTS" AND "EXHIBIT D -- EXCERPTS FROM MINNESOTA BUSINESS CORPORATION ACT 
RELATING TO DISSENTERS' RIGHTS." 

A form of Proxy and a Proxy Statement/Prospectus containing more detailed 
information with respect to the matters to be considered at the Special 
Meeting accompany this notice. 

You are cordially invited and urged to attend the Special Meeting in person. 
Whether or not you plan to attend, please complete, sign, date and promptly 
return the enclosed Proxy in the enclosed self-addressed, stamped envelope. 
If you attend the Special Meeting and desire to revoke your Proxy and vote in 
person, you may do so. In any event, a Proxy may be revoked at any time 
before it is voted. 

THE BOARD OF DIRECTORS OF DAIG UNANIMOUSLY RECOMMENDS THAT YOU VOTE IN FAVOR 
OF THE APPROVAL OF THE MERGER AGREEMENT. 

IN ORDER TO ASSURE YOUR REPRESENTATION AT THE SPECIAL MEETING, PLEASE 
COMPLETE, SIGN, DATE AND MAIL PROMPTLY THE ENCLOSED PROXY, WHICH IS BEING 
SOLICITED BY THE BOARD OF DIRECTORS OF DAIG, WHETHER OR NOT YOU PLAN TO 
ATTEND THE SPECIAL MEETING. AN ADDRESSED RETURN ENVELOPE WHICH REQUIRES NO 
POSTAGE IF MAILED IN THE UNITED STATES IS ENCLOSED FOR THAT PURPOSE. YOUR 
PROMPT COOPERATION WILL BE APPRECIATED.

                                PROSPECTUS OF 
                            ST. JUDE MEDICAL, INC. 
                            SHARES OF COMMON STOCK 
                                     AND 
                               PROXY STATEMENT 
                                     FOR 
                       SPECIAL MEETING OF SHAREHOLDERS 
                                      OF 
                               DAIG CORPORATION 
                          TO BE HELD ON MAY 30, 1996 
    

This Proxy Statement/Prospectus ("Proxy Statement/Prospectus") is being 
furnished to the shareholders of Daig Corporation, a Minnesota corporation 
("Daig"), in connection with the solicitation of proxies by the Board of 
Directors of Daig (the "Daig Board") for use at the Special Meeting of 
Shareholders of Daig to be held on May 30, 1996 at 9:00 a.m., local time, at 
The Kelly Inn, 2705 Annapolis Lane, Plymouth, Minnesota 55441, (the "Special 
Meeting"), or any adjournments or postponements thereof. 

At the Special Meeting, holders of shares of Daig Common Stock, par value 
$.01 per share ("Daig Common Stock"), will vote upon a proposal to approve 
the Agreement and Plan of Merger, dated as of January 29, 1996 (the "Merger 
Agreement"), by and among St. Jude Medical, Inc., a Minnesota corporation 
("SJM"), Partner Acquisition Corp., a Minnesota corporation and a wholly 
owned subsidiary of SJM ("Merger Subsidiary"), and Daig, pursuant to which 
Merger Subsidiary will be merged with and into Daig (the "Merger"). Daig will 
be the surviving corporation (the "Surviving Corporation") in the Merger and 
will become a wholly owned subsidiary of SJM. A copy of the Merger Agreement 
is attached to this Proxy Statement/Prospectus as Exhibit A and incorporated 
herein by reference. 

FOR INFORMATION CONCERNING CERTAIN RISKS WHICH SHOULD BE CONSIDERED BY DAIG 
SHAREHOLDERS IN EVALUATING THE MERGER, SEE "RISK FACTORS" LOCATED ON PAGE 18 
OF THIS PROXY STATEMENT/PROSPECTUS. 

Because the conversion ratio is fixed, a change in the market price of SJM 
Common Stock before the Merger would affect the value of the SJM Common Stock 
to be received in the Merger in exchange for the Daig Common Stock. THERE CAN 
BE NO ASSURANCE AS TO THE MARKET PRICE OF THE SJM COMMON STOCK AT ANY TIME 
BEFORE OR AFTER THE DATE ON WHICH THE MERGER BECOMES EFFECTIVE. Shareholders 
are urged to obtain current market quotations. 

In the Merger, each share of Daig Common Stock (other than shares as to which 
dissenters' rights have been perfected pursuant to Sections 302A.471 and 
302A.473 of the Minnesota Business Corporation Act (the "MBCA")) will be 
converted into the right to receive .651733 of a share of common stock, par 
value $.10 per share, of SJM ("SJM Common Stock") together with cash in lieu 
of any fractional share of SJM Common Stock to which a holder of Daig Common 
Stock would otherwise be entitled (after aggregating all fractional shares of 
SJM Common Stock to be received by such holder). A description of the terms 
of the Merger is set forth in this Proxy Statement/Prospectus. 

This Proxy Statement/Prospectus also constitutes the prospectus for the 
shares of SJM Common Stock to be issued in the Merger. SJM has filed a 
Registration Statement on Form S-4 (together with any amendments thereto, the 
"Registration Statement") with the Securities and Exchange Commission (the 
"Commission") of which this Proxy Statement/Prospectus is a part. All 
information concerning Daig contained in this Proxy Statement/Prospectus has 
been furnished by Daig, and all information concerning SJM contained in this 
Proxy Statement/Prospectus has been furnished by SJM. 

The approximate date on which this Proxy Statement/Prospectus and the 
accompanying proxy will first be mailed to Daig shareholders is May 1, 1996. 

THE SHARES OF SJM COMMON STOCK TO BE ISSUED IN THE MERGER HAVE NOT BEEN 
  APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION OR ANY 
    STATE SECURITIES COMMISSION NOR HAS THE SECURITIES AND EXCHANGE 
       COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE 
         ACCURACY OF ADEQUACY OF THIS PROXY STATEMENT/PROSPECTUS. 
           ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL 
                                   OFFENSE. 

   
The date of this Proxy Statement/Prospectus is May 1, 1996.

RECOMMENDATION                      The Board of Directors of Daig (the 
OF THE BOARD OF                     "Daig Board") has determined that the

                                    fair to, and in the best interests 
                                    of, Daig and its shareholders. 
                                    Accordingly, the Daig Board has 
                                    unanimously approved the Merger 
                                    Agreement and unanimously recommends 
                                    that the shareholders of Daig vote 
                                    FOR approval of the Merger Agreement. 
                                    The recommendation of the Daig Board 
                                    is based on a number of factors 
                                    described in "THE MERGER --

                                    Exhibit C and is incorporated herein 
                                    by reference. HOLDERS OF DAIG COMMON 
                                    STOCK ARE URGED TO, AND SHOULD, READ 
                                    SUCH OPINION IN ITS ENTIRETY. See

CONFLICTS OF INTEREST               In considering the recommendation of 
                                    the Daig Board with respect to the 
                                    Merger Agreement, holders of Daig 
                                    Common Stock should be aware that 
                                    certain members of Daig's management 
                                    and the Daig Board have interests in 
                                    the Merger that are in addition to, 
                                    and different from, the interests of 
                                    Daig shareholders generally. As 
                                    described above, pursuant to the 
                                    Shareholders' Agreement, Messrs. 
                                    Fleischhacker and Starks have (i) 
                                    agreed to vote certain of the shares 
                                    of Daig Common Stock held by them in 
                                    favor of approval of the Merger 
                                    Agreement, (ii) granted irrevocable 
                                    proxies to SJM to vote such shares 
                                    accordingly, and (iii) agreed not to 
                                    sell such shares except pursuant to 
                                    the Merger. In addition, each of Mr. 
                                    Fleischhacker and Mr. Starks has 
                                    entered into an employment agreement 
                                    with Daig that will become effective 
                                    at the Effective Time. The employment 
                                    agreements provide that Messrs. 
                                    Fleischhacker and Starks will be 
                                    employed as Chairman and Chief 
                                    Executive Officer and President and 
                                    Chief Operating Officer, 
                                    respectively, of Daig. These 
                                    agreements, which have a term of two 
                                    years each, set the annual base 
                                    salary for each individual ($300,000 
                                    for Mr. Fleischhacker and $250,000 
                                    for Mr. Starks), provide that each 
                                    individual shall be eligible to 
                                    participate in SJM's bonus, stock 
                                    option and benefits programs, and 
                                    contain certain provisions regarding 
                                    confidential information, assignment 
                                    of inventions, non-competition and 
                                    non-solicitation. Each of Mr. 
                                    Fleischhacker and Mr. Starks has also 
                                    entered into an agreement with SJM, 
                                    similar to the agreements currently 
                                    provided to SJM executives, with 
                                    regard to the treatment to be 
                                    accorded such executives upon the 
                                    occurrence of certain events that 
                                    result in a "change in control" (as 
                                    defined in such agreements) of SJM. 
                                    In addition, it is a condition to 
                                    Daig's obligation to consummate the 
                                    Merger that Mr. Starks (the 
                                    "Designated Director") shall have

                                    the term of the employment agreement, 
                                    Mr. Heinmiller will be entitled to a 
                                    bonus payment of $20,833.33 per month

                                    In addition, SJM has agreed to allow

                                    outstanding after the Effective Time. 
                                    SJM has also agreed with Mr. 
                                    Heinmiller that, in the event the 
                                    Daig Option has not been exercised 
                                    prior to the Closing Date, SJM will 
                                    file an amendment to a registration 
                                    statement covering the shares of its

                                    exercise the option and receive 
                                    registered shares of SJM Common 
                                    Stock. The Merger Agreement also 
                                    provides for certain indemnification 
                                    by SJM of the officers and directors 
                                    of Daig. See "RISK FACTORS -- 
                                    CONFLICTS OF INTEREST," "THE MERGER 
                                    -- CONFLICTS OF INTEREST" and

CONDITIONS TO                       The obligations of SJM and Daig to 
CONSUMMATION                        consummate the Merger are subject to 
OF THE MERGER                       various conditions, including 
                                    obtaining the requisite approval of 
                                    Daig's shareholders. In addition, it 
                                    is a condition precedent to the 
                                    obligation of SJM to consummate the 
                                    Merger that SJM receives from each of 
                                    Grant Thornton LLP and Ernst & Young 
                                    LLP a letter, dated as of the 
                                    Effective Date, confirming their 
                                    respective reports dated January 29, 
                                    1996, that with respect to Daig, 
                                    based upon procedures performed, 
                                    there have been no common stock 
                                    transactions, changes in equity 
                                    ownership or ownership affiliations 
                                    that would preclude SJM from 
                                    accounting for the Merger as a 
                                    pooling of interests, and that with 
                                    respect to SJM, the Merger will be 
                                    treated as a pooling of interests 
                                    under applicable accounting standards 
                                    and Commission rules and regulations. 
                                    Among other things, such letters will 
                                    be subject to the condition that less 
                                    than 10% of the merger consideration 
                                    will consist of cash, including (i) 
                                    cash paid to holders of outstanding 
                                    shares of Daig Common Stock who 
                                    dissent from the proposed Merger and 
                                    receive cash for their shares of 
                                    Common Stock, and (ii) cash paid in 
                                    the Merger in lieu of fractional 
                                    shares of SJM Common Stock. See

                                    Effective Time shall not have 
                                    occurred on or before September 30, 
                                    1996, (B) a court of competent 
                                    jurisdiction or an administrative, 
                                    governmental or regulatory authority 
                                    has issued a final non-appealable 
                                    order, decree or ruling, or taken any 
                                    other action, preventing the 
                                    consummation of the Merger, or (C) 
                                    the shareholders of Daig fail to 
                                    approve the Merger Agreement. 

                                    SJM may terminate the Merger 
                                    Agreement if (i) it is not in

                                    under the Merger Agreement and either 
                                    (A) Daig solicits from or negotiates 
                                    an Acquisition Proposal (as defined

                                    (iv) SJM has entered into a written 
                                    agreement under which SJM will be

                                    entity and, after such transaction,

                                    SJM Board prior to such transaction 
                                    would not constitute a majority of 
                                    the Board of Directors of the 
                                    acquiring or surviving corporation. 
                                    See "CERTAIN PROVISIONS OF THE MERGER 
                                    AGREEMENT -- TERMINATION." 

TERMINATION FEE                     If the Merger Agreement is terminated 
AND EXPENSES                        by SJM or Daig upon the occurrence of 
                                    certain events (including in 
                                    connection with certain third party 
                                    offers to acquire Daig), then Daig 
                                    will be required to pay to SJM within 
                                    five business days of a demand by 
                                    SJM, a termination fee of $10 
                                    million. This termination fee may 
                                    have the effect of discouraging 
                                    competing offers to acquire or merge 
                                    with Daig. The Merger Agreement 
                                    provides that all expenses incurred 
                                    in connection with such agreement and 
                                    the transactions contemplated thereby 
                                    will be paid by the party incurring 
                                    such expenses. See "CERTAIN 
                                    PROVISIONS OF THE MERGER AGREEMENT --

                                    the Merger for quotation on Nasdaq. 

REGULATORY APPROVALS                Each of SJM, Daig, Mr. Fleischhacker 
                                    and Mr. Starks filed notification and 
                                    report forms under the 
                                    Hart-Scott-Rodino Antitrust 
                                    Improvements Act of 1976, as amended 
                                    (the "HSR Act"), with the Federal 
                                    Trade Commission ("FTC") and the 
                                    Antitrust Division of the Department 
                                    of Justice (the "Antitrust Division") 
                                    on or about February 20, 1996. SJM 
                                    and Daig have received notice of 
                                    early termination of the waiting 
                                    period under the HSR Act effective 
                                    March 5, 1996. SJM and Daig do not 
                                    believe that any additional 
                                    regulatory approvals are required, 
                                    except for the filing and recordation 
                                    of appropriate merger documents as 
                                    required by the MBCA. See "THE MERGER 
                                    -- REGULATORY APPROVALS." 

DISSENTING                          If the Merger Agreement is approved 
SHAREHOLDERS' RIGHTS                at the Special Meeting and the Merger 
                                    is consummated, holders of Daig 
                                    Common Stock who file a written 
                                    notice of dissent before the vote and 
                                    who do not vote for the Merger 
                                    Agreement will have the right to 
                                    dissent from the Merger and to 
                                    receive the "fair value" of their 
                                    shares of Daig Common Stock in cash, 
                                    if and only if they fully comply with 
                                    Sections 302A.471 and 302A.473 of the 
                                    MBCA. The full text of these sections 
                                    of the MBCA is attached as Exhibit D 
                                    to this Proxy Statement/ Prospectus 
                                    and is incorporated herein by 
                                    reference. See "DISSENTING 
                                    SHAREHOLDERS' RIGHTS." 

EFFECTIVE TIME                      The Effective Time will occur as soon 
                                    as practicable after the requisite 
                                    approval of Daig's shareholders has 
                                    been obtained and all other 
                                    conditions to the Merger have been 
                                    satisfied or waived. The Effective 
                                    Time will occur upon the filing of 
                                    Articles of Merger with the Secretary 
                                    of State of the State of Minnesota. 

ACCOUNTING TREATMENT                The Merger will be accounted for 
                                    using the pooling of interests method 
                                    under generally accepted accounting 
                                    principles. Under the Merger 
                                    Agreement, it is a condition 
                                    precedent to the obligation of SJM to 
                                    consummate the Merger that it 
                                    receives letters as of the Effective 
                                    Date from the respective independent 
                                    accountants for SJM and Daig in the 
                                    form previously received on the date 
                                    of the Merger Agreement to the effect 
                                    that, with respect to Daig, based on 
                                    procedures performed, there have been 
                                    no common stock transactions, changes 
                                    in equity ownership or ownership 
                                    affiliations that would preclude SJM 
                                    from accounting for the Merger as a 
                                    pooling of interests, and that with 
                                    respect to SJM, the Merger will be 
                                    treated as a pooling of interests 
                                    under applicable accounting standards 
                                    and Commission rules and regulations. 
                                    Among other things, such letters from 
                                    the respective independent 
                                    accountants will be subject to the 
                                    condition that less than 10% of the 
                                    merger consideration will consist of 
                                    cash, including (i) cash paid to 
                                    holders of outstanding shares of Daig 
                                    Common Stock who dissent from the 
                                    proposed Merger and receive cash for 
                                    their shares of Daig Common Stock, 
                                    and (ii) cash paid in the Merger in 
                                    lieu of fractional shares of SJM 
                                    Common Stock. Daig and SJM are 
                                    obligated to use their best efforts 
                                    to cause the Merger to qualify, and 
                                    to refrain from taking any action 
                                    which could prevent the Merger from 
                                    qualifying, as a pooling of 
                                    interests. See "THE MERGER -- 
                                    ACCOUNTING TREATMENT," "CERTAIN 
                                    PROVISIONS OF THE MERGER AGREEMENT --

                                    MERGER" and "UNAUDITED PRO FORMA

CERTAIN FEDERAL TAX                 SJM and Daig expect that the Merger 
CONSEQUENCES                        will be treated as a tax-free 
                                    reorganization within the meaning of 
                                    Section 368 of the Internal Revenue 
                                    Code of 1986, as amended (the 
                                    "Code"), and that for federal income 
                                    tax purposes no gain or loss will be 
                                    recognized by any Daig shareholder 
                                    upon receipt of SJM Common Stock 
                                    pursuant to the Merger (except upon 
                                    the receipt of cash by holders who 
                                    exercise their dissenters' rights or 
                                    by other holders in lieu of 
                                    fractional shares of SJM Common 
                                    Stock). Furthermore, where cash is 
                                    received by holders of Daig Common 
                                    Stock pursuant to the Merger,

                                    Stock, gain or loss will be 
                                    recognized by such holders upon the 
                                    exchange of their shares of Daig 
                                    Common Stock for cash. This 
                                    expectation is based upon the opinion 
                                    of Dorsey & Whitney LLP ("Dorsey &

                                    Daig shareholders are urged to obtain 
                                    current market quotations for shares 
                                    of SJM Common Stock and Daig Common 
                                    Stock. 

                                    SJM has never paid cash dividends, 
                                    other than during the period from 
                                    April 1992 through August 1994, when 
                                    SJM paid quarterly dividends of $.067 
                                    per share to holders of SJM Common 
                                    Stock. SJM currently intends to 
                                    retain all of its earnings to finance 
                                    the continued growth of SJM's 
                                    business. Although SJM may consider 
                                    declaring and paying a dividend in 
                                    the future, there can be no assurance 
                                    that it will do so. No cash dividends 
                                    have been declared or paid on Daig 
                                    Common Stock since Daig's inception.

                                    five fiscal years ended December 31, 
                                    1995 for SJM and for the five fiscal 
                                    years ended September 30, 1995 for 
                                    Daig, has been obtained from the 
                                    consolidated financial statements of 
                                    SJM and Daig, which statements have 
                                    been audited by Ernst & Young LLP and 
                                    Grant Thornton LLP, respectively, 
                                    independent public accountants. The 
                                    selected financial data for Daig for 
                                    the three-month periods ended 
                                    December 31, 1995 and 1994 have been 
                                    obtained from Daig's unaudited 
                                    financial statements and include, in 
                                    the opinion of Daig management, all 
                                    adjustments necessary to present 
                                    fairly the data for such periods. 

                                    Daig's fiscal year ends on September 
                                    30 of each calendar year; therefore, 
                                    Daig's results for the fiscal years 
                                    ended September 30, 1995, 1994, and 
                                    1993, have been combined with SJM's 
                                    results for the years ended December 
                                    31, 1995, 1994 and 1993. It is 
                                    anticipated that, upon consummation 
                                    of the Merger, the fiscal year end of 
                                    the Surviving Corporation will be 
                                    changed to the Saturday nearest 
                                    December 31. 

                                    In addition, the pro forma combined 
                                    financial data for 1994 reflects the 
                                    acquisition by SJM of substantially 
                                    all the worldwide assets of the 
                                    cardiac rhythm management operations 
                                    of Siemens AG ("Pacesetter") as if it 
                                    had occurred as of the beginning of 
                                    1994. The acquisition of Pacesetter 
                                    was effective September 30, 1994, and 
                                    was accounted for as a purchase. The 
                                    historical SJM results for 1994 
                                    include the results of Pacesetter 
                                    only from October 1, 1994 to December 
                                    31, 1994. 

                                    This data should be read in 
                                    conjunction with the separate 
                                    consolidated financial statements and

                                    below is presented for illustrative 
                                    purposes only and is not necessarily

                                    expected to approximate $5.5 million, 
                                    substantially all of which are

                       NOTES TO SELECTED FINANCIAL DATA 
                            (DOLLARS IN THOUSANDS) 

(a) Results are not directly comparable due to the Pacesetter acquisition 
    effective September 30, 1994. Results for 1994 include a $40,800 pre-tax 
    ($25,300 after-tax) one-time charge for purchased research and 
    development associated with the Pacesetter acquisition. 

(b) Represents the combined results as if the acquisition of Pacesetter had 
    occurred as of the beginning of 1994. 

(c) The acquisition of Pacesetter was effective September 30, 1994, and was 
    accounted for under the purchase accounting method. Accordingly, 
    Pacesetter's results are included from the effective date of the 
    acquisition. 

(d) The pro forma amounts per SJM common share have been derived from the 
    historical consolidated financial statements of SJM and Daig, 
    incorporated by reference herein, and give effect to the Merger under the 
    pooling of interests method of accounting as if the Merger occurred on 
    the first day of the earliest period presented with .651733 of a share of 
    SJM Common Stock issued for each share of Daig Common Stock. 

(e) Reflects the pro forma amounts per SJM common share multiplied by the 
    Conversion Ratio of .651733. 

(f) Same as (d) and (e) above, except includes the results of Pacesetter as 
    if the acquisition had occurred as of the beginning of 1994. 


                                 RISK FACTORS 

SHAREHOLDERS OF DAIG SHOULD CONSIDER CAREFULLY ALL THE INFORMATION CONTAINED 
IN THIS PROXY STATEMENT/PROSPECTUS AND, IN PARTICULAR, THE FOLLOWING FACTORS. 

RAPID TECHNOLOGICAL CHANGE AND INTENSE COMPETITION 

The medical device market is highly competitive. SJM and Daig both compete 
with many companies, some of which have access to greater financial and other 
resources than SJM or Daig. Furthermore, the medical device market is 
characterized by intensive development efforts and rapidly advancing 
technology. SJM's and Daig's present and future products could be rendered 
obsolete or uneconomical by technological advances by one or more of SJM's 
and Daig's current or future competitors or by alternative therapies, 
including drug therapies. The future success of the combined company will 
depend, in large part, on its ability to anticipate technology advances and 
keep pace with other developers of medical devices and therapies. Competitive 
market forces may also adversely affect the prices at which the combined 
company sells its products. In particular, there has been significant 
consolidation in the medical device industry in recent years, partly in 
response to the increasing emphasis on cost containment in the industry, the 
emergence of large managed-care buying groups and hospital consolidations and 
the potential for increased federal regulation. Given these factors, there 
can be no assurance that the combined company resulting from the Merger will 
have the size or ability to compete successfully in the industry. 

COSTS OF AND RISKS ASSOCIATED WITH FDA AND OTHER GOVERNMENTAL REGULATION 

The medical devices manufactured and marketed by SJM and Daig are subject to 
rigorous regulation by the U.S. Food and Drug Administration ("FDA") and 
numerous other federal, state and foreign governmental authorities. The 
process of obtaining regulatory approvals to market a medical device, 
particularly from the FDA, can be costly and time-consuming, and there can be 
no assurance that such approvals will be granted for future products on a 
timely basis, if at all. Delays in receipt of, or failure to obtain, 
approvals for future products could result in delays in realizing product 
revenues or in substantial additional costs or have other material adverse 
effects on the combined company's business or results of operations. In 
addition, there can be no assurance that the combined company will be or will 
continue to be in compliance with applicable FDA and other material 
regulatory requirements. If the FDA were to conclude that the combined 
company was not in compliance with applicable laws or regulations, it could 
institute proceedings to detain or seize the combined company's products, 
issue a recall, impose operating restrictions, enjoin future violations and 
assess civil penalties against the combined company, its officers or its 
employees and could recommend criminal prosecution to the Department of 
Justice. Furthermore, the FDA could proceed to ban, or request recall, 
repair, replacement or refund of the cost of, any device manufactured or 
distributed by the combined company. Moreover, foreign governmental 
regulations have become increasingly stringent, and the combined company may 
be subject to more rigorous regulation by foreign governmental authorities in 
the future. SJM and Daig cannot predict whether any U.S. or foreign 
governmental regulation may be imposed in the future that may have a material 
adverse effect on the combined company.

subsidiary, see "THE COMPANIES -- ST. JUDE MEDICAL, INC. -- LITIGATION AND 
OTHER PROCEEDINGS." 
    

   
RISK OF PRODUCT LIABILITY LOSSES AND INADEQUATE OR UNAVAILABLE INSURANCE 
COVERAGE AND CERTAIN RELATED LITIGATION 
    

   
The medical device industry is subject to significant product liability 
claims and litigation, and the combined company will face an inherent risk of 
exposure to product liability claims alleging that the use of its products 
(or of products previously manufactured by SJM or Daig) has resulted in 
adverse effects to a patient or patients. Such claims could be asserted in 
the future against the combined company for past or future events not 
currently known to management of SJM or Daig. Any such claim could have an 
adverse effect on the combined company. As part of their respective risk 
management policies, SJM has obtained third party product liability insurance 
coverage, while Daig has elected to self-insure with respect to product 
liability risks. There can be no assurance that the combined company will 
continue to be able to obtain product liability insurance on commercially 
reasonable terms, if at all. Furthermore, there can be no assurance that 
product liability claims against the combined company will not exceed the 
coverage limits of any insurance policies or cause the combined company to 
record a self-insured loss. A product liability claim in an amount in excess 
of applicable insurance could have a material adverse effect on the combined 
company. 
    

For a description of certain litigation involving SJM related to product 
liability claims and insurance coverage, see "THE COMPANIES -- ST. JUDE 
MEDICAL, INC. -- LITIGATION AND OTHER PROCEEDINGS." 

POSSIBLE CHALLENGES TO PATENTS AND PROPRIETARY RIGHTS 

SJM and Daig are, and the combined company will be, dependent upon 
proprietary intellectual property. Both SJM and Daig rely on a combination of 
patents, trade secrets and nondisclosure agreements to protect their 
respective proprietary intellectual property, and the combined company will 
continue to do so. There can be no assurance that pending patent applications 
owned by SJM or Daig will result in patents issuing to SJM, Daig or the 
combined company, that patents issued to or licensed by SJM, Daig or the 
combined company in the past or in the future will not be challenged or 
circumvented by competitors or that such patents will be found to be valid or 
sufficiently broad to protect the combined company's technology or to provide 
the combined company with any competitive advantage. Third parties could also 
obtain patents that may require the combined company to negotiate licenses to 
conduct its business, but there can be no assurance that the required 
licenses would be available on reasonable terms or at all. The combined 
company will also rely on confidentiality agreements with certain employees, 
consultants and other parties to protect, in part, trade secrets and other 
proprietary technology. There can be no assurance that these agreements will 
not be breached, that the combined company will have adequate remedies for 
any breach, that others will not independently develop substantially 
equivalent proprietary information or that third parties will not otherwise 
gain access to the combined company's trade secrets or proprietary knowledge. 

There has been substantial litigation regarding patent and other intellectual 
property rights in the medical device industry generally. In the future, the 
combined company may be forced to defend itself against claims and legal 
actions alleging infringement of the intellectual property rights of others. 
Additionally, the combined company may find it necessary to initiate 
litigation in order to enforce its patent rights, to protect its trade 
secrets or know-how and to determine the scope and validity of the 
proprietary rights of others. Intellectual property litigation can be costly 
and time-consuming, and there can be no assurance that the combined company's 
intellectual property litigation expenses will not be significant in the 
future or that the outcome of such litigation will be favorable to the 
combined company. Adverse determinations in any such litigation could subject 
the combined company to significant liabilities to third parties, could 
require the combined company to seek licenses from third parties and could, 
if such licenses are not available, prevent the combined company from 
manufacturing, selling or using certain of its products, any of which could 
have a material adverse effect on the combined company. 

POSSIBLE DENIAL OF THIRD-PARTY REIMBURSEMENT 

SJM and Daig currently sell their products, and the combined company will 
sell its products, to hospitals, doctors and other health care providers, who 
receive reimbursement for the health care services provided to their patients 
from third-party payors, such as governmental programs (i.e., Medicare and 
Medicaid), private insurance plans and managed care programs. These 
third-party payors may deny reimbursement if they determine that a device 
used in a procedure was not used in accordance with cost-effective treatment 
methods, as determined by such third-party payor, or was used for an 
unapproved indication. Also, third-party payors are increasingly challenging 
the prices charged for medical products and services. There can be no 
assurance that the combined company's products will be considered 
cost-effective by third-party payors, that reimbursement will be available 
or, if available, that the third-party payors' reimbursement policies will 
not adversely affect the combined company's ability to sell its products 
profitably. 

GOVERNMENT INVESTIGATIONS 

INVESTIGATION BY OFFICE OF THE INSPECTOR GENERAL OF REIMBURSEMENT CLAIMS MADE 
BY CERTAIN CUSTOMERS. The Office of the Inspector General (the "OIG") of the 
United States Department of Health and Human Services ("HHS") is currently 
conducting an investigation regarding the possible submission of improper 
claims to the Medicare/Medicaid programs for reimbursement for procedures 
using cardiovascular medical devices that were not approved for marketing by 
the FDA at the time of use. Beginning in June 1994, approximately 130 
hospitals received subpoenas from HHS seeking information with respect to 
reimbursement for procedures using cardiovascular medical devices (including 
certain products manufactured by SJM and Daig, as well as numerous other 
manufacturers) that were subject to investigational exemptions or may not 
have been approved for marketing by the FDA at the time of use. The subpoenas 
also sought information regarding various types of remuneration, including 
payments, gifts, stock and stock options, received by the hospitals or their 
employees from manufacturers of medical devices. The OIG's investigation and 
any related change in Medicare/Medicaid reimbursement practices may 
discourage hospitals from participating in clinical trials or from including 
Medicare and Medicaid patients in clinical trials, which could lead to 
increased costs in the development of new products. In addition, civil and 
criminal sanctions may be imposed against any person found to have 
participated in an improper claim for reimbursement under Medicare/Medicaid, 
including possibly SJM, Daig or the combined company. Both SJM and Daig 
believe that it is too early to predict the possible outcome of this matter 
or when it will be resolved. There can be no assurance that the OIG's 
investigation or any resulting or related changes in third-party payors' 
reimbursement practices will not materially adversely affect the medical 
device industry in general or the combined company in particular. 

GERMAN GOVERNMENT INVESTIGATION. In 1994 a state prosecutor in Germany began 
an investigation of allegations of corruption in connection with the sale of 
heart valves. As part of that investigation, the prosecutor seized documents 
from SJM's offices in Germany as well as documents from certain competitors' 
offices. In December 1995, the state prosecutor announced that the 
investigation was continuing and had been broadened to include other medical 
devices. Subsequently, the United States Securities and Exchange Commission 
issued a formal order of private investigation covering sales practices of 
SJM and other manufacturers in Germany. 

POSSIBLE ADVERSE IMPACT OF HEALTH CARE REFORM PROPOSALS 

From time to time health care reform proposals have been introduced in the 
United States Congress that generally attempt to expand health care coverage 
and reduce total health care expenditures. Different proposals use various 
techniques to achieve these goals. Proposals often include such features as 
universal health care coverage, mandatory employer health insurance premiums, 
global expenditure limits, procedures for the review of new technologies, 
portability of insurance coverage and the creation of large buying groups 
intended to have considerable purchase power. Currently, legislative 
attention is focused particularly on certain proposed Medicare and Medicaid 
reforms. The ultimate scope of these reforms, if any, cannot yet be 
ascertained. Certain states have already made significant changes to their 
Medicaid programs and have adopted other health care reforms. Other states 
have reform proposals under consideration. In addition, such health care 
reform initiatives may accelerate the growing trend toward involvement by 
hospital administrators, purchasing managers and buying groups in purchasing 
decisions. This trend is expected to lead to increased emphasis on the 
cost-effectiveness of any treatment regimen. Regardless of whether any 
additional reform proposals are ultimately adopted, the trend toward cost 
controls and the requirement of more efficient utilization of medical 
therapies and procedures is expected to continue. Health care reform and the 
trend toward managed care may adversely affect the prices for, or the levels 
at which reimbursement is provided for, the combined company's products and 
the volume of products sold. In addition, certain health care reform 
initiatives, if enacted, may cause the combined company to incur increased 
expenses or reduced revenue in connection with bringing new products to 
market, which may adversely affect the combined company's business and 
results of operations. Similar initiatives to limit the growth of health care 
costs, including price regulation, are also underway in several other 
countries in which SJM and Daig currently do, or the combined company is 
expected to do, business. SJM and Daig are unable to predict at this time 
whether any such U.S. or foreign health care reform initiatives will be 
enacted or, if enacted, the final form such reforms would take or when such 
reforms would be implemented. Similarly, SJM and Daig are unable to predict 
what effect, if any, the enactment of any current or future U.S. or foreign 
health care reform initiatives might have on the combined company's business 
and results of operations. 

POTENTIAL FOR SUPPLY INTERRUPTIONS 

SJM purchases raw materials and other items from numerous suppliers for use 
in its products. SJM maintains sizeable inventories of up to three years of 
its projected requirements for certain materials, some of which are available 
only from a single vendor. SJM has been advised from time to time that 
certain of these vendors may terminate sales of products to customers that 
manufacture implantable medical devices in an effort to reduce their 
potential products liability exposure. Some of these vendors have modified 
their positions and have indicated a willingness to either temporarily 
continue to provide product until such time as an alternative vendor or 
product can be qualified or to reconsider the supply relationship. While SJM 
believes that alternative sources of raw materials are available and that 
there is sufficient lead time in which to qualify such other sources, any 
supply interruption could have a material adverse effect on SJM's ability to 
manufacture its products. 

DEPENDENCE ON KEY PERSONNEL 

The combined company's continued success will depend in large part on its 
ability to attract and retain highly qualified scientific, management, 
marketing and sales personnel. The competition for skilled personnel in SJM's 
and Daig's industry is intense. There is an inherent risk in transactions 
like the Merger that the combination process could result in the departure of 
key employees. There can be no assurance that the announcement of the 
proposed Merger will not adversely affect the combined company's ability to 
attract and retain personnel. The loss of a significant group of skilled 
personnel could adversely affect the combined company. 

PROPOSAL TO INCREASE AUTHORIZED SHARES OF SJM COMMON STOCK; OTHER 
ANTITAKEOVER CONSIDERATIONS 

At the SJM Annual Meeting of Shareholders scheduled to be held on May 9, 
1996, holders of SJM Common Stock will be asked to consider and vote upon a 
proposal to approve and adopt a proposed amendment to the SJM Articles of 
Incorporation to increase the number of authorized shares of SJM Common Stock 
from 100,000,000 to 250,000,000 (the "Amendment"). The Amendment is being 
sought because, following the consummation of the Merger and absent the 
Amendment, there would remain only approximately 11.4 million shares of 
authorized, unissued and unreserved shares of SJM Common Stock. The 
Amendment, if adopted, will make available to SJM additional authorized, 
unissued and unreserved shares of SJM Common Stock without the delay and cost 
of calling a special shareholders' meeting. The additional authorized SJM 
Common Stock could also be issued to make any attempt to acquire control of 
SJM more difficult and costly and thereby discourage attempts to acquire SJM 
or deprive holders of SJM Common Stock of the opportunity to sell their 
shares at a premium above market price. If an issuance of additional shares 
of SJM Common Stock is made on other than a pro rata basis to all 
shareholders, dilution of ownership interest and voting power of existing 
shareholders may occur and, depending on the consideration for which the 
shares were issued, could dilute earnings per share. If any plans or 
arrangements are made concerning the issuance of any such shares, holders of 
the then outstanding shares of SJM Common Stock may or may not be given the 
opportunity to vote thereon, depending upon the nature of any such 
transaction, the law applicable thereto, the policy of any stock exchange 
upon which the SJM Common Stock may be listed at such time and the judgment 
of the SJM Board. 

SJM is, and the combined company will continue to be, subject to a 
shareholders' rights plan which could in certain circumstances serve as a 
deterrent against a possible change of control not approved by the SJM Board. 
In addition, SJM is, and the combined company will be, subject to certain 
provisions of the Minnesota Business Corporation Act that limit the voting 
rights of shares acquired in "control share acquisitions" and restrict 
certain "business combinations." See "MATERIAL DIFFERENCES IN RIGHTS OF DAIG 
SHAREHOLDERS -- BUSINESS COMBINATIONS" and "-- SHAREHOLDERS' RIGHTS PLAN." 
These provisions and the rights plan could, in themselves or in connection 
with the foregoing factors, have the effect of discouraging certain attempts 
to acquire the combined company that could deprive the combined company's 
shareholders of opportunities to sell their shares of SJM Common Stock at 
prices higher than prevailing market prices. 

CONFLICTS OF INTEREST 

In considering the recommendation of the Daig Board with respect to the 
Merger Agreement, holders of Daig Common Stock should be aware that certain 
members of Daig's management and the Daig Board have interests in the Merger 
that are in addition to, and different from, the interests of Daig 
shareholders generally. As described above, pursuant to the Shareholders' 
Agreement, Messrs. Fleischhacker and Starks have (i) agreed to vote certain 
of the shares of Daig Common Stock held by them in favor of approval of the 
Merger Agreement, (ii) granted irrevocable proxies to SJM to vote such shares 
accordingly, and (iii) agreed not to sell such shares except pursuant to the 
Merger. In addition, each of Mr. Fleischhacker and Mr. Starks has entered 
into an employment agreement with Daig that will become effective at the 
Effective Time. The employment agreements provide that Messrs. Fleischhacker 
and Starks will be employed as Chairman and Chief Executive Officer and 
President and Chief Operating Officer, respectively, of Daig. These 
agreements, which have a term of two years each, set the annual base salary 
for each individual ($300,000 for Mr. Fleischhacker and $250,000 for Mr. 
Starks), provide that each individual shall be eligible to participate in 
SJM's bonus, stock option and benefits programs, and contain certain 
provisions regarding confidential information, assignment of inventions, 
non-competition and non-solicitation. Each of Mr. Fleischhacker and Mr. 
Starks has also entered into an agreement with SJM, similar to the agreements 
currently provided to SJM executives, with regard to the treatment to be 
accorded such executives upon the occurrence of certain events that result in 
a "change in control" (as defined in such agreements) of SJM. In addition, it 
is a condition to Daig's obligation to consummate the Merger that Mr. Starks 
(the "Designated Director") shall have been appointed to fill a newly created 
directorship on the SJM Board having a term expiring at the SJM annual 
meeting of shareholders to be held in 1997. Mr. Heinmiller, Daig's Vice 
President -- Finance and Administration, has entered into an employment 
agreement with Daig having a term of one year from the Effective Time of the 
Merger, unless earlier terminated. The agreement provides that Mr. Heinmiller 
will be employed as Daig's Vice President -- Finance and Administration at a 
base salary of $137,000 per annum together with a guaranteed annual bonus 
equal to 30% of this base salary, will receive an option to purchase 4,500 
shares of SJM Common Stock at the fair market value on the date of grant (the 
"Stock Option"), will have the right to participate in SJM's benefit programs 
and will be subject to certain provisions regarding confidential information, 
assignment of inventions, non-competition and non-solicitation. The Stock 
Option will vest at the rate of 25% per year over a period of four years 
provided Mr. Heinmiller remains continuously employed by Daig. If the 
employment agreement terminates under conditions other than those certain 
ones specifically described in the agreement, Mr. Heinmiller will be entitled 
to receive a bonus payment of $322,000. If the payment is not made and Mr. 
Heinmiller is not employed by Daig or an affiliate within one year after 
expiration of the term of the employment agreement, Mr. Heinmiller will be 
entitled to a bonus payment of $20,833.33 per month for each month in the 
one-year period following the expiration of the employment agreement in which 
he is not employed by Daig or an affiliate. In addition, SJM has agreed to 
allow a $440,000 interest-free loan from Daig to Mr. Heinmiller to remain 
outstanding after the Effective Time. SJM has also agreed with Mr. Heinmiller 
that, in the event the Daig Option has not been exercised prior to the 
Closing Date, SJM will file an amendment to a registration statement covering 
shares of its stock to permit Mr. Heinmiller to exercise the option and 
receive registered shares of SJM Common Stock. SJM is obligated under the 
Merger Agreement to indemnify and hold harmless directors, officers, 
employees and agents of Daig under certain circumstances, from claims, 
actions, suits or proceedings, and also has certain obligations with respect 
to employee benefit matters. The Daig Board was aware of these interests and 
considered them, among other matters, in approving the Merger Agreement. See 
"THE MERGER -- CONFLICTS OF INTEREST" and "CERTAIN PROVISIONS OF THE MERGER 
AGREEMENT -- CONDITIONS TO CONSUMMATION OF THE MERGER." 

                                THE COMPANIES 

ST. JUDE MEDICAL, INC. 

GENERAL. SJM designs, manufactures and markets medical devices and services 
for the cardiovascular segment of the medical device market. The Company's 
products are distributed in more than 70 countries worldwide through a 
combination of direct sales personnel and independent manufacturers' 
representatives. SJM's principal products are valve disease management 
products, including mechanical and tissue heart valves and annuloplasty ring 
products, and pacemaker products, including bradycardia pulse generators, 
leads and programmers. The main markets for SJM's products are the United 
States, Western Europe and Japan. 

Prior to the acquisition of Pacesetter from Siemens in September 1994, SJM 
derived the substantial majority of its revenues from heart valve products. 
SJM acquired substantially all of its pacemaker operations in the Pacesetter 
acquisition, which significantly expanded SJM's product offering and provided 
a platform for potential further diversification of its business. In 1995 
almost 63% of SJM's net sales were derived from pacemaker products, 
approximately 36% from heart valve products and the balance from cardiac 
assist products. Effective January 19, 1996, the Company sold its Cardiac 
Assist Division assets to C.R. Bard. 

Pacesetter pulse generators and leads treat patients with heart beats that 
are too slow or irregular, a condition known as bradycardia. Various models 
of bradycardia pulse generators and leads are produced by Pacesetter. Pulse 
generators can sense and produce impulses in both the upper and lower 
chambers of the heart, in appropriate relation to heart activity, and can be 
non-invasively programmed by the physician to adjust sensing, electrical 
pulse intensity, duration, rate, and other characteristics. The pulse 
generator, generally referred to as a pacemaker, contains a battery and 
electronic circuitry. It generates pacing pulses and monitors the heart's 
activity to sense abnormalities requiring correction. It is most often 
implanted pectorally in the upper chest just below the collarbone. The leads 
are insulated wires that carry the pulses to the heart and information from 
the heart back to the pacemaker. A pacemaker uses electrical currents 
equivalent to those in a healthy heart. 

Heart valves facilitate the one-way flow of blood in the heart and prevent 
significant backflow of blood into the heart and between the heart's 
chambers. Heart valve replacement or repair may be necessary because the 
natural heart valve has deteriorated due to congenital defects or disease. 
SJM offers both mechanical and tissue heart valves. The St. Jude Medical(R) 
mechanical heart valve is the most widely implanted valve in the world with 
over 650,000 valves implanted to-date. Also, in 1996, the Company executed an 
agreement to provide services relating to homografts. 

Annuloplasty rings are prosthetic devices used to repair diseased or damaged 
mitral heart valves. The ring can be adjusted either symmetrically or 
asymmetrically before, during or after placement to produce the desired valve 
annulus size and configuration. 

MERGER AGREEMENT WITH CYBERONICS, INC. In April 1996, SJM entered into a 
Merger Agreement with respect to the possible acquisition of Cyberonics, Inc. 
("Cyberonics") by SJM. Cyberonics designs, develops and markets medical 
devices for the treatment of epilepsy and other debilitating neurological 
disorders through vagus nerve stimulation. Under the terms of the merger 
agreement, if SJM elects to proceed with the merger, SJM would pay 
approximately $72 million in cash (approximately $7 per share) for the 
currently outstanding shares of Cyberonics. The merger agreement gives SJM 
the unilateral option to terminate the merger prior to closing (currently 
anticipated to occur in October 1996). The merger is subject to approval by a 
majority of the shareholders of Cyberonics and certain regulatory reviews. 
SJM has agreed that, upon approval of the merger by the shareholders of 
Cyberonics and regardless of whether it elects to proceed with the merger, it 
will purchase from Cyberonics $12 million in newly issued Cyberonics common 
stock at a price of $5.50 per share. 

Cyberonics' approach to the treatment of epilepsy utilizes "neuropacing" or 
the use of a pacemaker-like device to stimulate the vagus nerve 
intermittently and reduce the incidence of seizures. The Cyberonics device 
consists of an implantable pulse signal generator and a nerve stimulation 
lead. This system has been implanted in over 700 patients worldwide and has 
been approved for use in 23 countries, including the countries in the 
European Union. Cyberonics filed a pre-market approval ("PMA") application 
with the FDA in June 1993, which was amended in January 1995 following a 
request from the FDA for a second double-blind placebo-controlled study. 
Cyberonics has completed the enrollment phase of this confirmatory trial. The 
treatment phase of this trial is expected to be completed in mid-1996, and 
the submission of the final PMA to the FDA is expected before the end of 
1996. 

LITIGATION AND OTHER PROCEEDINGS.  On February 28, 1994, the predecessor 
organization to SJM's Pacesetter Systems, Inc. subsidiary entered into a 
consent decree in settlement of a lawsuit brought by the United States in 
U.S. District Court for the District of New Jersey. The consent decree, which 
remains in effect indefinitely, requires that Pacesetter's operations comply 
with the FDA's Good Manufacturing Practice regulations, including certain 
specific provisions of such regulations identified in the consent decree. The 
consent decree provides for FDA inspections and for the payment by the 
inspected facility of certain costs of the inspections. 

From 1987 to 1991, Siemens AG ("Siemens"), through its Pacesetter division 
and other affiliates, manufactured and sold approximately 32,000 model 1016T 
and 1026T pacemaker leads of which approximately 25,000 were sold in the 
United States. In 1991, Siemens ceased selling these products and issued a 
safety alert to physicians explaining that these pacemaker leads had a higher 
than expected failure rate due to an inner insulation problem. The safety 
alert recommended monitoring steps to minimize any risk posed by the devices. 
The FDA treated this notice as a Class I recall. In March 1993, Siemens was 
sued in federal district court in Cincinnati, Ohio (the "Wilson case"). The 
suit alleged that the model 1016T leads were negligently designed and 
manufactured. The suit sought class action status for patients whose 1016T 
leads had malfunctioned up to that time. The class status was granted by the 
court in September 1993. When SJM acquired Pacesetter from Siemens as of 
September 30, 1994, the purchase agreement specifically provided that Siemens 
retain all liability for the Wilson case as well as all other litigation that 
was pending or threatened before October 1, 1994. The purchase agreement also 
provided that SJM would assume liability for other product liability claims 
which arose after September 30, 1994. 

Siemens and SJM were named defendants in a class action suit filed in March 
1995 in federal district court in Houston, Texas for alleged defects in 
models 1016T and 1026T pacing leads (the "Hann case"). The suit sought class 
action status for patients who had inner insulation failures of these leads 
after March 22, 1993 and who were not members of the Wilson class. Siemens 
and SJM settled the Wilson and Hann cases in November 1995. SJM's anticipated 
financial responsibility for the settlement is approximately $7 million. The 
precise number of class members, and the corresponding financial liability, 
could increase or decrease as the process for filing claims is completed. The 
settlement agreement has an "opt out" provision for class members. Apart from 
this class action settlement, additional claims could be made or lawsuits 
brought by patients with these leads whose leads fail at a later date or 
whose leads fail for reasons outside the class definition. 

SJM's product liability insurance carrier, Steadfast, a wholly owned 
subsidiary of Zurich Insurance Company ("Zurich"), has denied coverage for 
these cases and has filed suit against SJM in federal district court in 
Minneapolis seeking rescission of the policy covering Pacesetter business 
retroactive to the date SJM acquired Pacesetter. Zurich alleges that SJM made 
material negligent misrepresentations to Zurich, including failure to 
disclose the Wilson case in order to procure the insurance policy. SJM has 
filed an answer denying Zurich's claim and has alleged that Zurich 
specifically had knowledge of the Wilson case. The terms of the product 
liability insurance policy which Zurich is seeking to rescind provide that 
SJM would be entitled to $10 million in coverage for the 1016T and 1026T 
pacemaker lead claims after payment by SJM of a self insured retention. SJM 
is investigating whether it may have claims against any entities, in addition 
to Zurich, arising from this situation. 

PARTNER ACQUISITION CORP. 

Merger Subsidiary, a wholly owned subsidiary of SJM, was formed in January 
1996 by SJM solely for the purpose of effecting the Merger. Upon consummation 
of the Merger, Merger Subsidiary will be merged with and into Daig, and 
Merger Subsidiary's separate corporate existence will thereupon cease. 

DAIG CORPORATION 

GENERAL. Daig designs, manufactures and markets specialized disposable 
cardiovascular devices for the electrophysiology and interventional 
cardiology markets, including percutaneous catheter introducers, diagnostic 
guidewires, electrophysiology catheters and bipolar temporary pacing 
catheters (used with external pacemakers). Daig employs direct sales 
representatives and independent distributors to sell its products to 
hospitals, hospital purchasing groups and OEMs worldwide. Daig packages its 
products both under its own label and under third-party private labels. 

CURRENT DAIG PRODUCTS. Percutaneous catheter introducers are used to create 
passageways for cardiovascular catheters from outside the human body through 
the skin into a vein, artery or other location inside the body. Daig's 
percutaneous catheter introducer products consist primarily of peel-away 
sheaths, sheaths with and without hemostasis valves, dilators, guidewires, 
repositioning sleeves, obturators and needles. All of these products are 
offered in a variety of sizes and packaging configurations. 

Diagnostic guidewires are used in conjunction with percutaneous catheter 
introducers to aid in the introduction of intravascular catheters. Daig's 
diagnostic guidewires are available in multiple lengths and incorporate a 
proprietary surface finish for lasting lubricity. 

Electrophysiology catheters are placed into the human body percutaneously 
(through the skin) to aid in the diagnosis and treatment of cardiac 
arrhythmias (abnormal heart rhythms). Between two and four electrophysiology 
catheters are generally used in each electrophysiology procedure. Daig's 
electrophysiology catheters are available in multiple configurations. 

Bipolar temporary pacing catheters are inserted percutaneously (through the 
skin) for temporary use (less than one hour to a maximum of one week) with 
external pacemakers to provide patient stabilization prior to implantation of 
a permanent pacemaker, following a heart attack, or during surgical 
procedures. Daig produces and markets several designs of bipolar temporary 
pacing catheters. 

In addition to these current products, Daig continually explores the 
possibility for new products and for new or expanded applications for 
existing products. Daig has received marketing clearance for a diagnostic 
angiography catheter and plans to launch this product commercially during the 
next year. Daig is also involved in various research and development efforts, 
including two related to its Livewire(tm) steerable electrophysiology 
catheter. One of these efforts aims to expand the approved diagnostic 
labeling of the Livewire(tm) steerable electrophysiology catheter to include 
certain ablation therapies. The other, which is being conducted pursuant to 
an FDA Investigational Device Exemption ("IDE"), involves a clinical trial to 
gather data in support of the use of the Livewire(tm) steerable 
electrophysiology catheter in combination with specialized guiding 
introducers as a cure for atrial fibrillation (a heart rhythm disorder). 
There can be no assurance that Daig (or the combined company if the Merger is 
consummated) will be successful in obtaining FDA clearance for such labeling 
or in commercially launching any such product or new product application. See 
"RISK FACTORS -- FDA AND OTHER GOVERNMENTAL REGULATION." 


                             THE SPECIAL MEETING 

GENERAL 

This Proxy Statement/Prospectus is being furnished to shareholders of Daig in 
connection with the solicitation of proxies by Daig for use at the Special 
Meeting to be held on May 30, 1996 at 9:00 a.m. local time at The Kelly Inn, 
2705 Annapolis Lane, Plymouth, Minnesota 55441, and any adjournments or 
postponements thereof. 

MATTERS TO BE CONSIDERED 

At the Special Meeting, the holders of record of Daig Common Stock as of the 
Record Date will consider and vote upon a proposal to approve the Merger 
Agreement. See "THE MERGER" and "CERTAIN PROVISIONS OF THE MERGER AGREEMENT." 

RECORD DATE; PROXIES 

   
The Daig Board has fixed the close of business on April 26, 1996 as the 
Record Date for determining the shareholders of Daig entitled to notice of 
and to vote at the Special Meeting. At the close of business on the Record 
Date, there were 15,236,144 shares of Daig Common Stock outstanding and 
entitled to vote, held of record by 360 holders. Holders of Daig Common Stock 
entitled to vote at the Special Meeting (including any adjournments or 
postponements thereof) may be represented by proxy at the Special Meeting by 
properly completing, executing and returning a proxy in the form enclosed 
with this Proxy Statement/Prospectus. Unless revoked between the date of such 
proxy and the date of the Special Meeting, such proxies will be voted at the 
Special Meeting and will be voted in accordance with the instructions 
indicated in such proxies. To the extent instructions are not indicated, such 
proxies will be voted and will be voted IN FAVOR of approval of the Merger 
Agreement. A Daig shareholder who has given a proxy may revoke such proxy at 
any time prior to its exercise at the Special Meeting by (i) giving written 
notice of revocation bearing a later date than the proxy to the Secretary of 
Daig, (ii) properly submitting to Daig a duly executed proxy card relating to 
the same shares bearing a later date or (iii) attending the Special Meeting 
and voting in person. Attendance at the Special Meeting will not in and of 
itself revoke a proxy. All written notices of revocation and other 
communications with respect to revocation of proxies by Daig shareholders 
should be addressed as follows: Daig Corporation, 14901 DeVeau Place, 
Minnetonka, MN 55345, Attention: Secretary, or hand-delivered to the 
Secretary of Daig before the vote is taken at the Special Meeting. 
    

HOLDERS OF DAIG COMMON STOCK SHOULD NOT SEND ANY STOCK CERTIFICATES WITH 
THEIR PROXY CARD. IF THE MERGER AGREEMENT IS APPROVED, HOLDERS OF DAIG COMMON 
STOCK WILL BE SENT A LETTER OF TRANSMITTAL WITH INSTRUCTIONS FOR SURRENDERING 
THEIR CERTIFICATES REPRESENTING SHARES OF DAIG COMMON STOCK. 

SOLICITATION OF PROXIES 

In addition to mailing this material to Daig shareholders, Daig has asked 
banks and brokers to forward copies to persons for whom they hold Daig Common 
Stock and to request authority for execution of proxies. Daig will reimburse 
the banks and brokers for their reasonable out-of-pocket expenses in doing 
so. Officers and regular employees of Daig may, without being additionally 
compensated, solicit proxies by mail, telephone, telegram or personal 
contact. All proxy solicitation expenses will be paid by Daig in connection 
with the solicitation of proxies for the Special Meeting. Daig has engaged 
Proxy Communications, Inc. to assist in proxy solicitation for a fee based on 
the number of items mailed that is not expected to exceed $1,000 plus postage 
and other customary expenses. 

VOTE REQUIRED AND QUORUM 

Approval of the Merger Agreement requires the affirmative vote of at least a 
majority of the shares of Daig Common Stock outstanding and entitled to vote 
at the Special Meeting. A vote by shareholders of Daig to approve the Merger 
Agreement will constitute a vote to approve the terms of, and the 
transactions contemplated by, the Merger Agreement (including the Merger). 
Holders of Daig Common Stock are entitled to one vote at the Special Meeting 
for each share of Daig Common Stock held of record at the close of business 
on the Record Date. A majority of the shares entitled to vote at the Special 
Meeting, represented in person or by proxy, constitutes a quorum for the 
transaction of business. Under the MBCA, abstentions and broker nonvotes will 
be considered present for purposes of determining a quorum. If an executed 
proxy card is returned and the shareholder has affirmatively abstained from 
voting on the Merger Agreement, the shares represented by such proxy will be 
considered present at the Special Meeting for purposes of determining a 
quorum and for purposes of calculating the vote, but will not be considered 
to have voted in favor of approval of the Merger Agreement. If an executed 
proxy card is returned by a broker holding shares in street name which 
indicates that the broker does not have discretionary authority as to certain 
shares to vote on the Merger Agreement, such shares will be considered 
present at the meeting for purposes of determining a quorum, but will not be 
considered to be represented at the meeting for purposes of calculating the 
vote with respect to such matter. FAILURE TO RETURN A PROPERLY EXECUTED PROXY 
CARD OR TO VOTE AT THE SPECIAL MEETING WILL HAVE THE SAME EFFECT AS A VOTE 
AGAINST APPROVAL OF THE MERGER AGREEMENT. 

At the close of business on April 26, 1996, directors and executive officers 
of Daig, in the aggregate, were entitled to vote 8,370,800 shares of Daig 
Common Stock, representing approximately 54.9% of the total shares entitled 
to vote at the Special Meeting. Daig expects that such directors and 
executive officers will vote all of such shares for approval of the Merger 
Agreement; to the extent that such directors and executive officers vote in 
accordance with Daig's expectations, approval of the Merger Agreement is 
assured. The two principal shareholders of Daig have entered into an 
agreement with SJM pursuant to which such shareholders have agreed to vote a 
portion of the shares of Daig Common Stock beneficially owned by each of them 
(and have given irrevocable proxies with respect to such shares), 
representing approximately 20% of the outstanding shares of Daig Common Stock 
entitled to vote at the Special Meeting, in favor of approval of the Merger 
Agreement. See "THE MERGER -- CONFLICTS OF INTEREST." 

The Daig Board has determined that the terms of the Merger Agreement are fair 
to, and in the best interests of, Daig and its shareholders. The Daig Board 
recommends unanimously that shareholders of Daig vote FOR approval of the 
Merger Agreement. 


                                  THE MERGER 

GENERAL 

The discussion in this Proxy Statement/Prospectus of the Merger and the 
description of the principal terms of the Merger are subject to and qualified 
in their entirety by reference to the Merger Agreement, a copy of which is 
attached to this Proxy Statement/Prospectus as Exhibit A and is incorporated 
herein by reference. 

BACKGROUND OF THE MERGER 

Management of Daig has from time to time in the past several years considered 
whether a strategic alliance with another corporation or the acquisition of 
Daig by another corporation might be in the best interests of Daig and its 
shareholders. Management considered this possibility in the past because of 
developing trends in the medical device industry as well as the healthcare 
industry generally. Included within these trends were the consolidation in 
the healthcare industry that was resulting in larger hospital systems with 
consolidated buying power for products like Daig's products, merger activity 
in the medical device industry and increased "bundling" of products within 
companies in the medical device industry as a result of mergers, strategic 
alliances, and distribution or licensing arrangements. Prior to 1995, 
management had concluded that, notwithstanding these factors, it was in the 
best interests of Daig to remain independent in order to further the growth 
of Daig's products and distribution capabilities. 

As a result of the acceleration of these industry factors, on September 19, 
1995, Mr. Fleischhacker (Daig's Chief Executive Officer), Mr. Starks (Daig's 
President) and Mr. Heinmiller (Daig's Vice President -- Finance and 
Administration) met with a representative of Dorsey & Whitney, special 
counsel to Daig, to consider their obligations as Daig renewed consideration 
of all of Daig's strategic opportunities. In particular, the parties 
discussed directors' and executive officers' fiduciary duties in the context 
of a strategic alliance or an acquisition of Daig, the steps involved, the 
role that a financial advisor could play, the importance of confidentiality 
and other matters relating to how the Daig Board and Daig management should 
proceed with regard to a potential transaction. Thereafter, Daig retained 
Goldman Sachs to act as Daig's financial advisor in relation to such a 
possible transaction. Through September and October, Goldman Sachs 
representatives met with Daig officers to review Daig's business, to develop 
information on Daig and to assist Daig in developing a preliminary list of 
approximately eight potential transaction partners. Thereafter, Goldman 
Sachs, on behalf of Daig, approached these potential partners on a 
preliminary basis to determine the level of interest in a potential 
transaction with Daig. Following Goldman Sachs' preliminary inquiries, 
management of Daig, together with Goldman Sachs, had further discussions with 
certain of these potential partners. Certain of these potential partners 
expressed varying degrees of interest, but with the exception of SJM, none of 
these expressions of interest resulted in a firm proposal. Furthermore, these 
expressions of interest seemed less desirable to the management of Daig 
because they involved anticipated price ranges that were too low, unfavorable 
accounting treatment for Daig and its shareholders, proposed timing that was 
too slow or breaking up Daig's business. SJM, on the other hand, expressed a 
significant level of interest following a meeting with management of Daig on 
October 23, 1995, at which Mr. Fleischhacker, Mr. Starks and Mr. Matricaria 
(SJM's Chief Executive Officer) discussed Daig's business, products and 
strategies. As the result of this expression of interest on SJM's part, which 
included pricing parameters, accounting treatment, timing and provisions 
regarding continuity of Daig's business that were acceptable to management of 
Daig, management of SJM and Daig met on November 1, November 21, and December 
1, 1995, to present information with respect to their respective companies 
and to discuss a potential SJM acquisition of Daig. On December 1, 1995, Mr. 
Starks also discussed possible per share prices with Mr. Matricaria . 

On December 8, 1995, the Daig Board held a meeting with all directors and 
representatives of Goldman Sachs and Dorsey & Whitney present. At this 
meeting management presented a review of the preliminary steps it had taken. 
A representative of Goldman Sachs gave a presentation regarding recent 
dynamics within the medical device industry, Daig's performance compared to 
the performance of other companies in the industry, SJM and information 
regarding other transactions within the industry. A representative of Dorsey 
& Whitney gave a presentation regarding the Daig Board's fiduciary duties. 
Following questions and answers and discussion among the directors, the Daig 
Board unanimously authorized management to continue with its negotiations. 
Management did so, responding to SJM's due diligence requests and engaging in 
negotiations regarding potential acquisition terms throughout December 1995. 

On December 18, 1995, a regular meeting of the SJM Board was held at which 
Mr. Matricaria and members of SJM's business development group discussed with 
the SJM Board the strategic fit between the two companies, as well as Daig's 
profit margins and growth rate. Management also described the progress of 
negotiations and that the transaction would likely have the structure of a 
stock-for-stock merger. 

On January 5, 1996, Mr. Starks and a representative of Goldman Sachs held a 
telephone conference with Mr. Matricaria regarding the pricing formula for 
the proposed acquisition and other matters, including the elimination of 
post-closing indemnity and a position on the SJM Board for a representative 
of Daig. On January 11, 1996, the Daig Board met again, with all directors 
present, to review progress since the December 8 meeting. Representatives of 
Goldman Sachs and Dorsey & Whitney also participated in this meeting. 
Following a presentation by Goldman Sachs, a further presentation by a 
representative of Dorsey & Whitney regarding directors' fiduciary duties, 
management's review of negotiations and a thorough discussion of possible 
approaches, the Daig Board unanimously authorized management to continue 
negotiations in an attempt to reach a satisfactory conclusion regarding the 
terms of a potential acquisition. On January 12, 1996, Mr. Fleischhacker and 
Mr. Starks again met with Mr. Matricaria to discuss transaction terms, 
including the pricing formula, Daig representation on the SJM Board and the 
future operation of Daig's business. After the January 12th meeting, 
management of Daig continued to discuss the possibility of a transaction with 
SJM. On January 18, 1996, management of Daig determined that a transaction on 
the terms discussed with SJM would be in the best interests of the Daig 
shareholders. Between January 18 and January 29, 1996, Daig and SJM completed 
their due diligence reviews and negotiated the terms of the Merger Agreement. 

On January 29, 1996, the Daig Board held a meeting to consider the proposed 
Merger Agreement with all directors and representatives of Goldman Sachs and 
Dorsey & Whitney present. Mr. Starks first reviewed the actions taken by 
management since January 11, 1996. The Daig Board then reviewed and discussed 
the terms of the Merger Agreement and the associated agreements with the 
representatives of Goldman Sachs and Dorsey & Whitney. A representative of 
Goldman Sachs updated their presentation regarding current industry 
conditions, SJM and Daig's performance. Following this presentation, the 
representative of Goldman Sachs delivered the opinion of Goldman Sachs to the 
Daig Board that, as of such date, the Conversion Ratio pursuant to the Merger 
Agreement was fair to the holders of Daig Common Stock. See "-- OPINION OF 
FINANCIAL ADVISOR TO DAIG." After an extended discussion of the matters 
presented at the meeting, the Daig Board unanimously concluded that it was in 
the best interests of Daig and its shareholders for Daig to enter into the 
Merger Agreement and to consummate the Merger, and voted unanimously to 
recommend that the Daig shareholders approve the Merger and the Merger 
Agreement. 

On January 29, 1996, the SJM Board held a meeting to consider the proposed 
Merger. Officers of SJM reviewed and discussed with the Board the background 
of the Merger, the terms of the Merger Agreement and the industry factors to 
be considered in connection with evaluating the Merger. After extensive 
discussion, the directors of SJM, among other things, unanimously (i) 
determined that it would be in the best interests of SJM to consummate the 
Merger, (ii) approved the form and terms of the Merger Agreement, (iii) 
authorized SJM's officers to undertake all acts necessary or desirable to 
effectuate the Merger and (iv) appointed American Stock Transfer & Trust 
Company as the exchange agent for the exchange of shares of SJM Common Stock 
and shares of Daig Common Stock in the Merger. 

Following the meetings of the Daig Board and the SJM Board on January 29, 
1996, Daig and SJM entered into the Merger Agreement. 

SJM'S REASONS FOR THE MERGER 

The SJM Board has determined that the terms of the Merger Agreement and the 
transactions contemplated thereby are fair to, and in the best interests of, 
SJM. Accordingly, the SJM Board has unanimously approved the Merger 
Agreement, In reaching its determination, the SJM Board consulted with SJM's 
management, as well as its legal counsel and financial advisor, and 
considered a number of factors, including, without limitation, the following: 

       1. The SJM Board believes that its customers are seeking to do 
    business with fewer vendors and only those suppliers that can deliver a 
    high volume of broad-based technologies that are truly cost-effective and, 
    where possible, improve outcomes. The Merger responds to the changing 
    needs of this evolving customer base by filling gaps in SJM's existing 
    cardiac rhythm management (CRM) products, thus allowing the combined 
    company to offer an expanded product line. 

       2. The SJM Board believes that combining SJM and Daig will create a 
    company that is better positioned than either company would be separately 
    to adapt to, and benefit from, technological and other developments in the 
    treatment of cardiac disease resulting in acceleration of product and 
    technological innovation. 

       3. The SJM Board believes that the Merger will offer potential cost 
    advantages through the consolidation and integration of certain 
    distribution, sales and administrative operations and functions. The SJM 
    Board also believes that the Merger will result in greater sales of Daig's 
    products due to the combined company's more extensive marketing and sales 
    organization and its larger network of established customers. 

       4. The SJM Board believes that the changing health care environment, 
    including the increasing emphasis on cost containment, the emergence of 
    large managed-care buying groups and hospital consolidations and the 
    potential for increased federal regulation, requires that a successful 
    medical device company have a certain critical mass to compete effectively 
    in the market and to absorb the pressures of the managed-care structure. 
    This belief is supported by the consolidation and refocusing taking place 
    among manufacturers and suppliers of pharmaceuticals and medical devices. 

       5. The SJM Board believes that SJM and Daig each have an extremely 
    capable management team with an established track record. The SJM Board 
    expects the health care industry to continue to be characterized by 
    uncertainty and the likelihood of continuing consolidation and believes 
    that by combining the expertise of the two management teams, the combined 
    company will be better able to respond to these changes and to take 
    advantage of the opportunities that these changes may create. 

       6. The SJM Board believes that by bringing together two companies 
    which have substantial cash flow and relatively little long-term debt, the 
    Merger will result in a combined company that will have a financial 
    condition superior to that of SJM alone, resulting in an enhanced ability 
    to secure financing on favorable terms and thereby increasing the combined 
    company's ability to pursue future growth through acquisition or the 
    development of existing, new or complementary businesses and technologies. 

       7. The SJM Board considered the terms of the Merger Agreement, 
    including the dilutive impact of the issuance of SJM Common Stock in 
    connection with the Merger, and determined, based in part on the advice of 
    SJM's financial advisor, that the terms were fair to existing holders of 
    SJM Common Stock. 

       8. The SJM Board considered the premium being paid in the Merger over 
    the historical market prices for Daig Common Stock in light of the 
    consideration being paid in connection with other acquisitions in the 
    medical device industry for companies that had displayed a high degree of 
    revenue and profitability growth, considering that Daig had also shown 
    strong profitability in recent periods. 

In view of the wide variety of factors considered by the SJM Board, it did 
not find it practicable to quantify or otherwise attempt to assign relative 
weights to the specific factors considered in making its determination. 
Consequently, the SJM Board did not quantify the assumptions and results of 
its analysis in reaching its determination that the Merger is fair to, and in 
the best interest of, SJM. 

DAIG'S REASONS FOR THE MERGER; RECOMMENDATION OF THE DAIG BOARD 

The Daig Board has determined that the terms of the Merger Agreement and the 
transactions contemplated thereby are fair to, and in the best interests of, 
Daig and its shareholders. Accordingly the Daig Board has unanimously 
approved the Merger Agreement and recommends unanimously that the 
shareholders of Daig vote FOR approval of the Merger Agreement. In reaching 
its determination, the Daig Board consulted with Daig's management, as well 
as its legal counsel and financial advisor, and considered a number of 
factors. As described above, over the past two years Daig's management has 
monitored trends and competitive conditions in the medical device industry. 
In particular, management has noted a recent move toward increased 
consolidation in the medical device industry, which it understands to be 
driven largely by the need to broaden product lines, to gain market share, to 
increase international market penetration (given lengthy FDA approval times) 
and to enable bundling and capitation arrangements with hospitals and managed 
care organizations, which are increasingly taking actions that favor medical 
device companies offering large and cost-effective product portfolios. As the 
result of concern over the possible impact of these trends, Daig retained 
Goldman Sachs and, following discussions with Goldman Sachs, initiated the 
contacts described above that led to the execution of the Merger Agreement. 
See "THE MERGER -- BACKGROUND OF THE MERGER." 

In addition, the Daig Board considered other factors including: (i) the fact 
that three of Daig's competitors in the electrophysiology market have already 
been acquired by large medical device companies; (ii) potential revenue 
synergies, including the ability to market Daig's products through SJM's 
international distribution channels and to sell Daig's products together with 
SJM's products; (iii) potential cost synergies, through consolidation and 
integration of certain manufacturing, distribution, sales and administrative 
operations and functions; (iv) public and non-public information concerning 
the financial performance and condition, business operations and prospects of 
each of SJM and Daig on the basis of which the Daig Board considered the 
potential value of Daig as a stand-alone entity and as a part of SJM and the 
value of the SJM Common Stock as merger consideration; (v) the fact that the 
consideration per share of Daig Common Stock that may be received under the 
Merger Agreement represents a premium over recent historical trading prices 
of Daig Common Stock; (vi) the fact that the Merger would allow holders of 
Daig Common Stock to retain an equity interest in the combined company and to 
achieve substantially greater liquidity than could be achieved by continuing 
to hold Daig Common Stock; (vii) the Conversion Ratio and recent trading 
prices for Daig Common Stock and SJM Common Stock; (viii) the likelihood of 
consummation of the Merger including the terms and conditions of the Merger 
Agreement; (ix) the expectation that the Merger will be nontaxable to the 
shareholders of Daig for federal income tax purposes; (x) the opportunity to 
participate in the management of SJM through the representation on the SJM 
Board of the Designated Director; and (xi) the financial analyses of Goldman 
Sachs described herein and the oral opinion of Goldman Sachs subsequently 
confirmed in writing, that as of January 29, 1996, the Conversion Ratio 
pursuant to the Merger Agreement was fair to the holders of Daig Common Stock 
(see "THE MERGER -- OPINION OF FINANCIAL ADVISOR TO DAIG"). 

The Daig Board also considered the following potentially negative material 
factors in its deliberations concerning the Merger: (i) the loss of control 
over the future operations of Daig following the Merger; (ii) the risk that 
the benefits sought to be achieved in the Merger may not be achieved; (iii) 
the fact that SJM Common Stock was trading at or near historical highs and 
that recent price/earnings multiples of SJM Common Stock are high relative to 
its historical price/earnings multiples; (iv) certain interests in the Merger 
of members of Daig's management and the Daig Board (see "THE MERGER -- 
CONFLICTS OF INTEREST"); and (v) the other risks described above under "RISK 
FACTORS." The Daig Board discussed with Daig's management and Daig's advisors 
the prospects for combinations with companies other than SJM and whether the 
benefits described above could be achieved through any such combination, as 
well as the risks and benefits of a stand-alone strategy. After reviewing 
these potentially negative factors, the Daig Board concluded that they were 
outweighed by the positive factors described above and accordingly determined 
that the Merger is fair to, and in the best interests of, Daig and its 
shareholders. 

In view of the wide variety of factors considered by the Daig Board, it did 
not find it practicable to quantify, or otherwise attempt to assign relative 
weights to the specific factors considered in making its determination. 
Consequently, the Daig Board did not quantify the assumptions and results of 
its analysis in reaching its determination that the Merger is fair to, and in 
the best interests of, Daig and its shareholders. THE DAIG BOARD UNANIMOUSLY 
RECOMMENDS THAT THE DAIG SHAREHOLDERS VOTE FOR APPROVAL OF THE MERGER 
AGREEMENT. 

EFFECTIVE TIME 

If the Merger Agreement is approved by the requisite vote of Daig's 
shareholders and all other conditions to the Merger are satisfied or waived, 
the Merger will be consummated and effected at the time of the filing of the 
Articles of Merger with the Secretary of State of the State of Minnesota (or 
such later time as agreed to by the parties to the Merger Agreement and 
specified in such Articles of Merger). The Merger Agreement provides that SJM 
and Daig will cause the Effective Time to occur as soon as practicable, but 
in no event later than the second business day following the satisfaction or 
waiver of all of the conditions set forth in the Merger Agreement. The Merger 
Agreement may be terminated and the Merger may be abandoned at any time prior 
to the Effective Time by either SJM or Daig under certain circumstances, 
whether before or after approval of the Merger Agreement by the Daig 
shareholders. See "CERTAIN PROVISIONS OF THE MERGER AGREEMENT -- 
TERMINATION." 

CONVERSION OF SHARES OF DAIG COMMON STOCK 

If the required approval of Daig's shareholders is obtained and all other 
conditions to the Merger are satisfied or waived, then Merger Subsidiary will 
be merged with and into Daig, which will be the Surviving Corporation and 
which will thereupon become a wholly owned subsidiary of SJM. In the Merger, 
each share of Daig Common Stock outstanding immediately prior to the 
Effective Time (other than shares as to which dissenters' rights have been 
perfected) will be converted into the right to receive .651733 of a share of 
SJM Common Stock together with cash in lieu of any fractional share of SJM 
Common Stock to which a holder of Daig Common Stock would otherwise be 
entitled (after aggregating all fractional shares of SJM Common Stock to be 
received by such holder). In the event that the average closing sale price of 
SJM Common Stock as quoted on Nasdaq for the 20 trading days immediately 
preceding the fifth trading day prior to the Effective Time is less than 
$34.00, Daig will be entitled to terminate the Merger Agreement without 
penalty to Daig. 

OPINION OF FINANCIAL ADVISOR TO DAIG 

On January 29, 1996, Goldman Sachs delivered its oral opinion to the Board of 
Directors of Daig that as of the date of such opinion, the Conversion Ratio 
pursuant to the Merger Agreement was fair to the holders of Daig Common 
Stock. Such oral opinion was subsequently confirmed in writing. 

THE FULL TEXT OF THE WRITTEN OPINION OF GOLDMAN SACHS DATED JANUARY 29, 1996, 
WHICH SETS FORTH ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE 
REVIEW UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED HERETO AS 
EXHIBIT C TO THIS PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY 
REFERENCE. STOCKHOLDERS OF DAIG ARE URGED TO, AND SHOULD, READ SUCH OPINION 
IN ITS ENTIRETY. 

   
In connection with its opinion, Goldman Sachs reviewed (i) the Merger 
Agreement; (ii) Annual Reports on Form 10-K of Daig for the five fiscal years 
ended September 30, 1995; (iii) Annual Reports to Stockholders and Annual 
Reports on Form 10-K of SJM for the five years ended December 31, 1994; (iv) 
certain interim reports to stockholders and Quarterly Reports on Form 10-Q of 
Daig and SJM; (v) certain other communications from Daig and SJM to their 
respective stockholders; and (vi) certain internal financial analyses and 
forecasts for Daig and SJM prepared by their respective managements. Goldman 
Sachs also held discussions with members of the senior management of Daig and 
SJM regarding the past and current business operations, financial condition, 
and future prospects of their respective companies and Goldman Sachs reviewed 
financial forecasts prepared for each business by their respective 
managements. In addition, Goldman Sachs reviewed the reported price and 
trading activity for the Daig Common Stock and SJM Common Stock, compared 
certain financial and stock market information for Daig and SJM with similar 
information for certain other companies the securities of which are publicly 
traded, reviewed the financial terms of certain recent business combinations 
in the medical device and hospital supply industries specifically and in 
other industries generally. 
    

Goldman Sachs relied without independent verification upon the accuracy and 
completeness of all of the financial and other information reviewed by it for 
purposes of its opinion. In that regard, Goldman Sachs assumed, with Daig's 
consent, that the financial forecasts, including, without limitation, 
projected cost savings and operating synergies resulting from the Merger had 
been reasonably prepared on a basis reflecting the best currently available 
judgments and estimates of Daig and SJM and that such forecasts will be 
realized in the amounts and at the times contemplated thereby. In addition, 
Goldman Sachs had not made an independent evaluation or appraisal of the 
assets and liabilities of Daig or SJM or any of their respective 
subsidiaries, and Goldman Sachs had not been furnished with any such 
evaluation or appraisal. Goldman Sachs had assumed with Daig's consent that 
the Merger will be accounted for as a pooling of interests under generally 
accepted accounting principles. 

The following is a summary of the material financial analyses used by Goldman 
Sachs in connection with providing its oral opinion to Daig's Board of 
Directors on January 29, 1996, which oral opinion was subsequently confirmed 
in writing. 

       (i) SELECTED COMPANIES ANALYSIS. Goldman Sachs reviewed and compared 
    certain financial information relating to Daig and SJM to corresponding 
    financial information, ratios and public market multiples for seven 
    publicly-traded corporations, including SJM, with large market 
    capitalizations: Arrow International Inc., Boston Scientific Corporation, 
    C.R. Bard Inc., Guidant Corporation, Medtronic, Inc., Thermo Cardiosystems 
    Inc. and SJM (the "Selected Companies"). The Selected Companies were 
    chosen because they are publicly-traded companies with operations that for 
    purposes of analysis may be considered similar to Daig and SJM. Goldman 
    Sachs calculated and compared various financial multiples and ratios. The 
    multiples of Daig and SJM were calculated using a price of $23.25 per 
    share of Daig Common Stock and $44.63 per share of SJM Common Stock, the 
    closing price of such shares on January 26, 1996, and the multiples of the 
    Selected Companies were calculated using closing market prices for such 
    companies on January 26, 1996. Except as set forth below, the multiples 
    and ratios for Daig, SJM and each of the Selected Companies were based on 
    the most recent publicly available information. With respect to the 
    Selected Companies, Goldman Sachs considered levered market capitalization 
    (i.e., market value of common equity plus estimated market value of debt 
    less cash) as a multiple of latest twelve months ("LTM") revenues and as a 
    multiple of LTM earnings before interest and taxes ("EBIT"). Goldman 
    Sachs' analyses of the Selected Companies indicated levered multiples of 
    LTM revenues, which ranged from a low of 2.0x to a high of 136.5x, with a 
    mean of 23.8x and a median of 4.5x, and LTM EBIT, which ranged from a low 
    of 12.9x to a high of 27.7x, with a mean of 16.9x and a median of 16.8x, 
    compared to levered multiples of 8.8x and 25.5x, respectively, for Daig 
    and levered multiples of 4.4x and 16.6x, respectively, for SJM. Goldman 
    Sachs also considered for the Selected Companies LTM and estimated 
    calendar year 1995 and 1996 price/earnings ratios (based on Institutional 
    Broker Estimate System ("IBES") estimates as of January 15, 1996), which 
    for the Selected Companies ranged from a low of 22.5x to a high of 54.5x, 
    with a mean of 29.9x and a median of 26.8x, for LTM, a low of 16.8x to a 
    high of 42.8x, with a mean of 25.5x and a median of 24.7x, for estimated 
    calendar year 1995, and a low of 14.9x to a high of 30.7x, with a mean of 
    20.1x and a median of 21.1x, for estimated calendar year 1996, compared to 
    35.8x, 29.1x and 23.7x, respectively, for Daig and 25.4x, 24.7x and 21.1x, 
    respectively, for SJM; LTM net margins and LTM EBIT margins for the 
    Selected Companies, ranged from a low of 7.1% to a high of 26.3%, with a 
    mean of 15.6% and a median of 16.2%, and a low of 5.6% to a high of 30.7%, 
    with a mean of 21.6% and a median of 25.0%, respectively, compared to 
    25.8% and 34.3%, respectively, for Daig and 17.4% and 26.5%, respectively, 
    for SJM; and five-year earnings per share ("EPS") growth rate (based on 
    IBES estimates) for the Selected Companies ranged from a low of 12.0% to a 
    high of 50.0%, with a mean of 22.2% and a median of 19.0%, compared to 
    25.0% for Daig and 14.6% for SJM. IBES is a data service which monitors 
    and publishes a compilation of earnings estimates produced by selected 
    research analysts on companies of interest to investors. The estimated 
    calendar year 1996 price/earnings ratio to five-year EPS growth rate for 
    the Selected Companies ranged from a low of 0.9x to a high of 1.6x, with a 
    mean of 1.2x and a median of 1.3x, compared to 0.9x for Daig and 1.4x for 
    SJM. The review also indicated that total debt to capitalization for the 
    Selected Companies ranged from a low of 2.9% to a high of 57.0%, with a 
    mean of 22.6% and a median of 18.7%, compared to 0.0% for Daig and 17.3% 
    for SJM. 

       Goldman Sachs reviewed and compared certain financial information 
    relating to Daig and SJM to corresponding financial information, ratios 
    and public market multiples for three publicly traded corporations with 
    small market capitalizations: Endosonics Corp., InControl, Inc. and 
    Ventritex Inc. (the "Small Cap Selected Companies"). Goldman Sachs 
    calculated and compared various financial multiples and ratios. The 
    multiples of Daig and SJM were calculated using a price of $23.25 per 
    share of Daig Common Stock and $44.63 per share of SJM Common Stock, the 
    closing price of such shares on January 26, 1996, and the multiples of the 
    Small Cap Selected Companies were calculated using the closing market 
    prices for such companies on January 26, 1996. Except as set forth below, 
    the multiples and ratios for Daig, SJM and each of the Small Cap Selected 
    Companies were based on the most recent publicly available information. 
    With respect to the Small Cap Selected Companies, Goldman Sachs considered 
    levered market capitalization as a multiple of LTM revenues. Goldman 
    Sachs' analyses of the Small Cap Selected Companies indicated levered 
    multiples of LTM revenues for the two companies for which such data was 
    available, which ranged from a low of 3.2x to a high of 9.6x, compared to 
    a levered multiple of 8.8x for Daig and 4.4x for SJM. Goldman Sachs also 
    considered for the Small Cap Selected Companies estimated calendar year 
    1995 price/earnings ratios (based on IBES estimates as of January 15, 
    1996), which for the one company for which such data was available was 
    40.8x, compared to 29.1x for Daig and 24.7x for SJM; and five-year EPS 
    growth rate (based on IBES estimates) for the two Small Cap Selected 
    Companies for which such information was available ranged from a low of 
    30.0% to a high of 50.0%, compared to 25.0% for Daig and 14.6% for SJM. 
    The estimated calendar year 1996 price/earnings ratio to five-year EPS 
    growth rate for the two Small Cap Selected Companies for which such 
    information was available was 0.0x, compared to 0.9x for Daig and 1.4x for 
    SJM. The review also indicated that total debt to capitalization for the 
    Small Cap Selected Companies ranged from a low of 0.0% to a high of 14.5%, 
    compared to 0.0% for Daig and 17.3% for SJM. 

       (ii) DISCOUNTED CASH FLOW ANALYSIS. Goldman Sachs performed a 
    discounted cash flow analysis under the following four scenarios: (a) 
    using Daig's managements forecasts (the "Management Case"), (b) using 
    Daig's managements forecasts, but assuming only 90% of the revenues 
    forecasted are achieved and margins remain constant (the "Second Case"), 
    (c) using Daig's managements forecasts, but assuming only 75% of the 
    revenues forecasted are achieved and margins remain constant (the "Third 
    Case"), and (d) using IBES earnings estimates through 1997 and assuming 
    25% growth rate per year thereafter, depreciation and capital expenditures 
    increase by 25% per year and working capital remains the same (the "Fourth 
    Case"). Goldman Sachs calculated a net present value of free cash flows 
    for the years 1996 through 2000 using discount rates ranging from 20.0% to 
    30.0%. Goldman Sachs calculated Daig's terminal values in the year 2000 
    based on multiples ranging from 8.0x EBIT to 20.0x EBIT. These terminal 
    values were then discounted to present value using discount rates ranging 
    from 20.0% to 30.0%. 

       Using Daig's terminal values in the year 2000 based on multiples 
    ranging from 8.0x EBIT to 20.0x EBIT and discounting these terminal values 
    to present value using discount rates ranging from 20.0% to 30.0%, the 
    implied per share values (which is the present value of cash flows plus 
    the terminal value, less net debt, divided by the number of Shares 
    outstanding) ranged from a low of $18 to a high of $60 in the Management 
    Case, from a low of $16 to a high of $54 in the Second Case, from a low of 
    $13 to a high of $45 in the Third Case and from a low of $8 to a high of 
    $26 in the Fourth Case. 

       (iii) SELECTED TRANSACTIONS ANALYSIS. Goldman Sachs analyzed certain 
    information relating to thirty-four selected transactions in the medical 
    device and hospital supply industries since 1982 where the aggregate 
    merger consideration exceeded $200 million (the "Selected Transactions"). 
    The comparisons to Daig referred to below assume a conversion ratio of 
    0.653 (which is higher than the 0.651733 Conversion Ratio for the Merger) 
    and aggregate equity merger consideration of $444.0 million (the 
    approximate amount of the merger consideration is based on the closing 
    price of SJM Common Stock on January 26, 1996). Such analysis indicated 
    that for the Selected Transactions aggregate consideration as a multiple 
    of (i) LTM sales ranged from a low of 0.4x to a high of 8.1x, with a mean 
    of 2.7x and a median of 1.8x, as compared to 11.1x for Daig (based on 
    actual 1995 net sales), (ii) LTM EBIT ranged from a low of 8.3x to a high 
    of 39.1x, with a mean of 17.7x and a median of 16.0x, as compared to 32.6x 
    for Daig (based on actual 1995 EBIT), and (iii) LTM net income ranged from 
    a low of 13.3x to a high of 58.5x, with a mean of 34.2x and a median of 
    31.9x, as compared to 45.5x for Daig (based on actual 1995 EPS). Such 
    analysis also indicated that for the Selected Transactions, the percentage 
    of premium paid (based on the stock price of the companies four weeks 
    prior to the announcement of the transaction) ranged from a low of 1.0% to 
    a high of 132.4%, with a mean of 55.9% and a median of 55.6%, as compared 
    to 25.3% for Daig. 

       (iv) PRO FORMA MERGER ANALYSIS. Goldman Sachs prepared pro forma 
    analyses of the financial impact of the Merger. Using earnings estimates 
    for Daig (adjusted to reflect a December 31 fiscal year end) and SJM 
    prepared by their respective managements for the years 1996, 1997 and 
    1998, Goldman Sachs compared the EPS of SJM Common Stock, on a standalone 
    basis, to the EPS of the common stock of the combined companies on a pro 
    forma basis. These comparisons were based on the following assumptions: 
    (i) a conversion ratio of 0.653 (which is higher than the 0.651733 
    Conversion Ratio for the Merger), (ii) aggregate merger consideration of 
    $444.0 million, and (iii) price to be paid in the Merger per Share of Daig 
    Common Stock of $29.14 (assumes a market value of $44.63 per share of SJM 
    Common Stock at the Effective Time of the Merger). Based on such analyses, 
    the proposed transaction would be dilutive to SJM's stockholders on an 
    earnings per share basis in 1996 and accretive to SJM's stockholders on an 
    earnings per share basis in 1997 and 1998. 

       Goldman Sachs also prepared a pro forma merger analysis of the 
    financial impact of the Merger using earnings estimates for Daig (adjusted 
    to reflect a December 31 fiscal year end) and SJM prepared by IBES for the 
    years 1996, 1997 and 1998. Goldman Sachs compared the EPS of SJM Common 
    Stock, on a standalone basis, to the EPS of the common stock of the 
    combined companies on a pro forma basis. These comparisons were based on 
    the following assumptions: (i) a conversion ratio of 0.653 (which is 
    higher than the 0.651733 Conversion Ratio for the Merger), (ii) aggregate 
    merger consideration of $444.0 million, and (iii) price to be paid in the 
    Merger per Share of Daig Common Stock of $29.14 (assumes a market value of 
    $44.63 per share of SJM Common Stock at the Effective Time of the Merger). 
    Based on such analyses, the proposed transaction would be dilutive to 
    SJM's stockholders on an earnings per share basis in 1996, 1997 and 1998. 

       (v) CONTRIBUTION ANALYSIS. Goldman Sachs reviewed certain historical 
    and estimated future operating and financial information (including, among 
    other things, revenues, research and development expenses, selling, 
    general and administrative expenses, EBIT, net income, net cash and total 
    assets) for Daig, SJM and the combined entity resulting from the Merger 
    based on historical figures, IBES estimates, Daig's management's estimates 
    (adjusted to reflect a December 31 fiscal year end) and Goldman Sachs' 
    research as of November 1995 regarding SJM. The analysis indicated that, 
    using a price of $23.25 per share of Daig Common Stock and $44.63 per 
    share of SJM Common Stock, the closing price of such shares on January 26, 
    1996, the Daig stockholders would contribute 10.2% of the equity market 
    capitalization and 9.7% of the levered market capitalization of the 
    combined entity. Goldman Sachs analyzed the relative contribution of Daig 
    and SJM to the combined companies based on actual 1994 and estimated years 
    1995, 1996 and 1997. This analysis indicated that (i) in 1994 Daig would 
    have contributed 8.6% to combined revenues, 11.4% to combined research and 
    development expenses, 8.2% to combined selling, general and administrative 
    expenses, 7.3% to combined EBIT and 9.3% to combined net income, (ii) in 
    estimated calendar year 1995 Daig would contribute 5.5% to combined 
    revenues, 5.1% to combined research and development expenses, 4.4% to 
    combined selling, general and administrative expenses, 6.9% to combined 
    EBIT and 7.5% to combined net income, (iii) in estimated calendar year 
    1996 Daig would contribute 7.2% to combined revenues, 7.3% to combined 
    research and development expenses, 5.9% to combined selling, general and 
    administrative expenses, 8.9% to combined EBIT, 8.9% to combined net 
    income and 8.0% to combined net income based on IBES estimates, and (iv) 
    in estimated calendar year 1997 Daig would contribute 10.5% to combined 
    revenues, 10.4% to combined research and development expenses, 8.6% to 
    combined selling, general and administrative expenses, 12.9% to combined 
    EBIT, 12.5% to combined net income and 8.6% to combined net income based 
    on IBES estimates. The analysis also indicated that Daig would contribute 
    11.0% of net cash of the combined companies and 3.4% of total assets to 
    the combined companies. 

       (vi) ANALYSIS AT VARIOUS PRICES. Goldman Sachs prepared a financial 
    analysis of the Merger and calculated various financial multiples assuming 
    a conversion ratio of 0.653 (which is higher than the 0.651733 Conversion 
    Ratio for the Merger) and based upon (i) the following amounts of 
    aggregate equity consideration (assuming 15,236,144 shares of Daig Common 
    Stock outstanding on September 30, 1995): $398.0 million, $422.8 million, 
    $444.0 million, $447.7 million and $472.6 million and (ii) the following 
    amounts of aggregate levered consideration: $379.1 million, $404.0 
    million, $425.1 million, $428.9 million and $453.7 million. Since the 
    total value of the aggregate equity consideration and aggregate levered 
    consideration will fluctuate with increases or decreases in the market 
    value of the SJM Common Stock, Goldman Sachs performed this analysis 
    assuming the foregoing range. Goldman Sachs calculated multiples of the 
    aggregate levered consideration to: (a) net sales; (b) earnings before 
    interest, taxes, depreciation and amortization ("EBITDA"); and (c) EBIT. 
    This analysis indicated that multiples of (i) 1995 net sales ranged from a 
    low 9.9x to a high of 11.8x; (ii) estimated 1996 net sales ranged from a 
    low of 7.1x to a high of 8.5x; and (iii) estimated 1997 net sales ranged 
    from a low of 4.5x to a high of 5.4x. This analysis also indicated that 
    multiples of (i) 1995 EBITDA ranged from a low of 26.6x to a high of 
    31.8x, (ii) estimated 1996 EBITDA ranged from a low of 19.2x to a high of 
    23.0x and (iii) estimated 1997 EBITDA ranged from a low of 11.8x to a high 
    of 14.1x. This analysis also indicated that multiples of (i) 1995 EBIT 
    ranged from a low of 29.1x to a high of 34.8x, (ii) estimated 1996 EBIT 
    ranged from a low of 20.6x to a high of 24.7x and (iii) estimated 1997 
    EBIT ranged from a low of 12.4x to a high of 14.8x. Goldman Sachs also 
    calculated multiples of the aggregate equity consideration to: (a) EPS and 
    (b) book value. This analysis indicated that multiples of (i) 1995 EPS 
    ranged from a low of 40.8x to a high of 48.5x, (ii) estimated 1996 EPS 
    (based on Daig's management estimates) ranged from a low of 32.2x to a 
    high of 38.3x, (iii) estimated 1997 EPS (based on Daig's management 
    estimates) ranged from a low of 19.5x to a high of 23.1x, (iv) estimated 
    1996 EPS (based on IBES estimates) ranged from a low of 32.7x to a high of 
    38.8x and (v) estimated 1997 EPS (based on IBES estimates) ranged from a 
    low of 26.7x to a high of 31.7x. This analysis also indicated that 
    multiples of 1995 book value ranged from a low of 12.5x to a high of 
    14.9x. 

       

The preparation of a fairness opinion is a complex process and is not 
necessarily susceptible to partial analysis or summary description. Selecting 
portions of the analyses or of the summary set forth above, without 
considering the analysis as a whole, could create an incomplete view of the 
processes underlying Goldman Sachs' opinion. In arriving at its fairness 
determination, Goldman Sachs considered the results of all such analyses. No 
company or transaction used in the above analyses as a comparison is 
identical to Daig or SJM or the contemplated transaction. The analyses were 
prepared solely for purposes of Goldman Sachs' providing its opinion to the 
Daig Board of Directors as to the fairness of the Conversion Ratio pursuant 
to the Merger Agreement to the holders of Daig Common Stock and do not 
purport to be appraisals or necessarily reflect the prices at which 
businesses or securities actually may be sold. Analyses based upon forecasts 
of future results are not necessarily indicative of actual future results, 
which may be significantly more or less favorable than suggested by such 
analyses. Because such analyses are inherently subject to uncertainty, being 
based upon numerous factors or events beyond the control the parties or their 
respective advisors, none of Daig, SJM, Goldman Sachs or any other person 
assumes responsibility if future results are materially different from those 
forecast. 

As described above, Goldman Sachs' opinion to the Board of Directors of Daig 
was one of many factors taken into consideration by the Daig Board of 
Directors in making its determination to approve the Merger Agreement. The 
foregoing summary does not purport to be a complete description of the 
analysis performed by Goldman Sachs and is qualified by reference to the 
written opinion of Goldman Sachs set forth in Exhibit C hereto. 

Goldman Sachs, as part of its investment banking business, is continually 
engaged in the valuation of businesses and their securities in connection 
with mergers and acquisitions, negotiated underwritings, competitive 
biddings, secondary distributions of listed and unlisted securities, private 
placements, and valuations for estate, corporate and other purposes. Daig 
selected Goldman Sachs as its financial advisor because it is a nationally 
recognized investment banking firm that has substantial experience in 
transactions similar to the Merger. Goldman Sachs has provided certain 
investment banking services to SJM from time to time. 

Goldman Sachs provides a full range of financial, advisory and brokerage 
services and in the course of its normal trading activities may from time to 
time effect transactions and hold positions in the securities or options on 
securities of Daig and/or SJM for its own account and for the account of 
customers. As of January 25, 1996, Goldman Sachs had a long position of 
91,786 shares of SJM Common Stock. 

   
Pursuant to a letter agreement dated September 25, 1995 (the "Engagement 
Letter"), Daig engaged Goldman Sachs to act as its financial advisor in 
connection with the possible sale of all or a portion of Daig. Upon execution 
of the Engagement Letter, Daig paid Goldman Sachs a fee of $150,000, such fee 
to be credited toward the payment of the transaction fee set forth below. 
Pursuant to the terms of the Engagement Letter, Daig has agreed to pay 
Goldman Sachs (i) upon the purchase of 50% or more of the Daig Common Stock 
or the assets (based on book value thereof) of Daig in one or a series of 
transactions, including, but not limited to, private or open market purchases 
of stock, a tender offer, a merger or a sale by Daig of its stock or assets, 
a transaction fee of 1.0% of the aggregate consideration paid in such 
transactions and (ii) if less than 50% of the outstanding Daig Common Stock 
or assets (based on the book value thereof) of Daig is acquired in the manner 
set forth in (i) above, a transaction fee to be mutually agreed upon by 
Goldman Sachs and Daig but in no event less than 1.0% of the aggregate 
consideration paid in such transactions. Daig has agreed to reimburse Goldman 
Sachs for its reasonable out-of-pocket expenses, including attorney's fees, 
and to indemnify Goldman Sachs against certain liabilities, including certain 
liabilities under the federal securities laws. SJM and Daig estimate that 
Goldman Sachs will receive a transaction fee of between $4.0 million and $4.4 
million in connection with the consummation of the Merger and will receive 
reimbursement for approximately $75,000 in out-of-pocket expenses. 
    


CERTAIN FEDERAL TAX CONSEQUENCES 

SJM and Daig expect that the Merger will be treated as a tax-free 
reorganization within the meaning of Section 368 of the Code and that for 
federal income tax purposes no gain or loss will be recognized by any Daig 
shareholder upon receipt of SJM Common Stock pursuant to the Merger (except 
upon the receipt of cash by holders who exercise their dissenters' rights or 
by other holders in lieu of fractional shares of SJM Common Stock). The 
Internal Revenue Service (the "Service") has not been and will not be asked 
to rule upon the tax consequences of the Merger. Instead, Daig will rely upon 
the opinion of Dorsey & Whitney, its special counsel, as to certain federal 
income tax consequences of the Merger to the Daig shareholders. The opinion 
of Dorsey & Whitney is based upon the facts described herein, various 
representations and covenants made by Daig, SJM and certain shareholders of 
Daig, and subject to various assumptions and qualifications. The opinion of 
Dorsey & Whitney is also based upon the Code, regulations now in effect 
thereunder, current administrative rulings and practice, and judicial 
authority, all of which are subject to change. Unlike a ruling from the 
Service, an opinion of counsel is not binding on the Service and there can be 
no assurance, and none is hereby given, that the Service will not take a 
position contrary to one or more positions reflected herein or that the 
opinion will be upheld by the courts if challenged by the Service. EACH 
HOLDER OF DAIG COMMON STOCK IS URGED TO CONSULT SUCH HOLDER'S OWN TAX ADVISOR 
AS TO THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER, AND ALSO AS TO ANY 
STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES, BASED ON SUCH HOLDER'S OWN 
PARTICULAR FACTS AND CIRCUMSTANCES. 

Based upon the facts described herein, various representations and covenants 
made by Daig, SJM and certain shareholders of Daig, and subject to various 
assumptions and qualifications, Dorsey & Whitney has delivered its opinion 
that the following federal income tax consequences will result from the 
Merger: 

(i) The Merger will qualify as a reorganization within the meaning of 
Sections 368(a)(1)(A) and 368(a)(2)(E) of the Code and Daig, SJM and Merger 
Subsidiary each will be a party to the reorganization within the meaning of 
Section 368(b) of the Code; 

(ii) No income, gain or loss will be recognized by Daig or SJM as a result of 
the consummation of the Merger; 

(iii) Subject to items (vi) and (vii) below, no gain or loss will be 
recognized by the holders of Daig Common Stock upon the exchange of Daig 
Common Stock solely for the SJM Common Stock pursuant to the Merger; 

(iv) The basis of the SJM Common Stock received by a shareholder of Daig 
pursuant to the Merger, including any fractional shares deemed received as 
described in item (vi) below, will be the same as the basis of the Daig 
Common Stock surrendered in exchange therefor; 

(v) The holding period of the SJM Common Stock received by a shareholder of 
Daig pursuant to the Merger will include the period during which the Daig 
Common Stock surrendered therefor was held, provided the Daig Common Stock is 
a capital asset in the hands of the shareholder of Daig at the time of the 
Merger; 

(vi) Where cash is received by a holder of Daig Common Stock pursuant to the 
Merger in lieu of fractional shares of SJM Common Stock, the cash payment 
will be treated as received by the holder of Daig Common Stock as a 
distribution in redemption of the fractional share interest and such 
shareholder will recognize gain or loss, subject to the provisions and 
limitations of Section 302 of the Code; and 

(vii) Where cash is received by a holder of Daig Common Stock who exercises 
dissenters' rights, the cash payment will be treated as received by the 
holder of Daig Common Stock as a distribution in redemption of such 
shareholder's Daig Common Stock and such shareholder will recognize gain or 
loss, subject to the provisions and limitations of Section 302 of the Code. 

The opinion described above is based upon certain assumptions, including the 
assumption that the holders of Daig Common Stock do not have any plan or 
intention to sell, exchange or otherwise dispose of a number of shares of SJM 
Common Stock received pursuant to the Merger that would reduce the ownership 
of SJM Common Stock by all of the pre-Merger holders of Daig Common Stock to 
a number of shares having a value, as of the date of the Merger, of less than 
50% of the value of all of the formerly outstanding Daig Common Stock as of 
the same date. 

The foregoing is only a general description of certain anticipated federal 
income tax consequences of the Merger without regard to the particular facts 
and circumstances of the tax situation of each shareholder of Daig. It does 
not discuss all of the consequences that may be relevant to Daig shareholders 
entitled to special treatment under the Code (such as insurance companies, 
dealers in securities, exempt organizations or foreign persons) or to 
shareholders of Daig who acquired their Daig Common Stock pursuant to the 
exercise of employee stock options or otherwise as compensation. The summary 
set forth above does not purport to be a complete analysis of all potential 
tax effects of the transactions contemplated by the Merger Agreement or the 
Merger itself. No information is provided herein with respect to the tax 
consequences, if any, of the Merger under state, local or foreign tax laws. 

ACCOUNTING TREATMENT 

The Merger will be accounted for using the pooling of interests method under 
generally accepted accounting principles. The pooling of interests method of 
accounting is intended to present as a single interest two or more common 
stockholder interests which were previously independent. The pooling of 
interests method of accounting assumes that the combining companies have been 
merged from inception. Consequently, the historical financial statements for 
periods prior to consummation of the Merger are restated as though the 
companies had been combined. See "CERTAIN PROVISIONS OF THE MERGER AGREEMENT 
- -- CONDITIONS TO CONSUMMATION OF THE MERGER" and "UNAUDITED PRO FORMA 
CONDENSED COMBINED FINANCIAL STATEMENTS." 

Under the Merger Agreement, neither SJM nor any of its subsidiaries may take 
any action that would prevent the Merger from qualifying for pooling of 
interests accounting treatment. See "CERTAIN PROVISIONS OF THE MERGER 
AGREEMENT -- CONDUCT OF BUSINESS PENDING THE MERGER." In addition, it is a 
condition precedent to the obligation of SJM to consummate the Merger that 
SJM receives from each of Grant Thornton LLP and Ernst & Young LLP a letter, 
dated as of the Effective Date, confirming their respective reports dated 
January 29, 1996, that with respect to Daig, based upon procedures performed, 
there have been no common stock transactions, changes in equity ownership or 
ownership affiliations that would preclude SJM from accounting for the Merger 
as a pooling of interests, and that with respect to SJM, the Merger will be 
treated as a pooling of interests under applicable accounting standards and 
Commission rules and regulations. Among other things, such letters will be 
subject to the condition that less than 10% of the merger consideration will 
consist of cash, including (i) cash paid to holders of outstanding shares of 
Daig Common Stock who dissent from the proposed Merger and receive cash for 
their shares of Common Stock, and (ii) cash paid in the Merger in lieu of 
fractional shares of SJM Common Stock. See "CERTAIN PROVISIONS OF THE MERGER 
AGREEMENT -- CONDITIONS TO CONSUMMATION OF THE MERGER." 

RESALE OF SJM COMMON STOCK; AGREEMENTS WITH AFFILIATES OF DAIG AND SJM 

The shares of SJM Common Stock to be issued in the Merger will be registered 
under the Securities Act on a registration statement of which this Proxy 
Statement/Prospectus is a part, thereby allowing such shares of SJM Common 
Stock to be traded without restriction by all holders not deemed to be 
affiliates of Daig prior to the consummation of the Merger. 

Prior to the execution of the Merger Agreement, Daig caused each principal 
executive officer, each director and each other person whom Daig deemed, in 
its reasonable judgment, to be an affiliate of Daig to deliver to SJM an 
agreement (each a "Daig Affiliate Agreement") pursuant to which, among other 
things, each such person agreed not to sell, transfer or otherwise dispose of 
any shares of Daig Common Stock or SJM Common Stock during the period 
immediately preceding the Effective Time and until such time after the 
Effective Time as SJM has publicly released a report including the combined 
financial results of SJM and Daig for a period of at least 30 days of 
post-Effective Time combined operations of SJM and Daig within the meaning of 
Commission Accounting Series Release No. 130, as amended. Furthermore, 
pursuant to the Daig Affiliate Agreements, each of such persons will agree to 
refrain from the sale or transfer of any SJM Common Stock received in 
connection with the Merger except in accordance with the provisions of the 
Securities Act and the general rules and regulations promulgated thereunder. 
Compliance with Daig Affiliate Agreements is an element required for SJM to 
account for the Merger as a pooling of interests. 

Affiliates of SJM will also be subject to certain limitations on their 
ability to sell, transfer or otherwise dispose of shares of SJM Common Stock 
during the period preceding the Merger. SJM will, at least 30 days prior to 
the Effective Date, enter into an agreement with each person SJM believes to 
be an affiliate of SJM relating to the restrictions on transfer resulting 
from the Merger being accounted for as a pooling of interests in accordance 
with generally accepted accounting principles and all published rules, 
regulations and policies of the Commission. 

REGULATORY APPROVALS 

The Merger is subject to the requirements of the HSR Act and the rules 
promulgated thereunder by the FTC, which prohibit consummation of the Merger 
unless notice has been given and certain information has been furnished to 
the Antitrust Division and the FTC and certain waiting period requirements 
have been satisfied. 

Each of SJM, Daig, Mr. Fleischhacker and Mr. Starks filed notification and 
report forms under the HSR Act with the FTC and the Antitrust Division on or 
about February 20, 1996. SJM and Daig received notice of early termination of 
the waiting period under the HSR Act effective March 5, 1996. Nevertheless, 
at any time before or after the Effective Time, the FTC or the Antitrust 
Division could take such action under federal antitrust laws as it should 
deem necessary or desirable in the public interest, including seeking to 
enjoin the Merger or seeking the divestiture of Daig or SJM, in whole or in 
part, or the divestiture of substantial assets of SJM, its subsidiaries or 
Daig. State Attorneys General and private parties may also bring legal 
actions under the federal or state antitrust laws under certain 
circumstances. Based on an examination of information available to SJM and 
Daig relating to the businesses in which SJM, its subsidiaries and Daig are 
engaged, SJM and Daig believe that consummation of the Merger will not 
violate any antitrust laws. There can be no assurance, however, that a 
challenge to the proposed Merger on antitrust grounds will not be made or, if 
such a challenge is made, that SJM and Daig will prevail. 

Neither SJM nor Daig is aware of any other governmental approvals or actions 
that may be required for consummation of the Merger, except for the filing 
and recordation of appropriate Merger documents as required by the MBCA. 
Pursuant to the Merger Agreement, SJM and Daig each have agreed to use 
commercially reasonable efforts to do all things necessary to consummate the 
transactions contemplated by the Merger Agreement. 

NASDAQ NATIONAL MARKET LISTING 

SJM has filed an application to list the shares of SJM Common Stock to be 
issued in connection with the Merger for quotation on Nasdaq. The approval of 
such listing is a condition to consummation of the Merger. 

CERTAIN EXCHANGE PROCEDURES 

As of the Effective Time, SJM will deposit, or will cause to be deposited 
with American Stock Transfer & Trust Company or such other bank or trust 
company as may be designated by SJM (the "Exchange Agent"), for the benefit 
of the holders of Daig Common Stock, certificates representing the shares of 
SJM Common Stock (such certificates for shares of SJM Common Stock, together 
with any dividends or distributions with respect thereto and any cash in lieu 
of fractional shares of SJM Common stock, being hereinafter referred to as 
the "Exchange Fund") issuable as of the Effective Time in exchange for 
outstanding shares of Daig Common Stock. The Exchange Agent will, pursuant to 
irrevocable instructions, deliver the SJM Common Stock contemplated to be 
issued out of the Exchange Fund. 

As promptly as practicable after the Effective Time, SJM will cause the 
Exchange Agent to mail to each holder of a certificate or certificates which 
immediately prior to the Effective Time represented outstanding shares of 
Daig Common Stock (the "Certificates") (i) a letter of transmittal (which 
shall specify that delivery will be effected, and risk of loss and title to 
the Certificates will pass, only upon proper delivery of the Certificates to 
the Exchange Agent, and shall be in customary form) and (ii) instructions for 
use in effecting the surrender of the Certificates in exchange for 
certificates representing shares of SJM Common Stock. Upon surrender to the 
Exchange Agent of a Certificate for cancellation, together with such letter 
of transmittal, duly executed, and such other documents as may be required 
pursuant to such instructions, the holder of such Certificate will be 
entitled to receive in exchange therefor a certificate representing that 
number of whole shares of SJM Common Stock which such holder has the right to 
receive in respect of the Daig Common Stock formerly represented by such 
Certificate after taking into account all Daig Common Stock then held by such 
holder, together with cash in lieu of any fractional share of SJM Common 
Stock to which such holder is entitled (after aggregating all fractional 
shares of SJM Common Stock to be received by the holder) and which have 
become payable with respect to such whole number of shares of SJM Common 
Stock and which have not previously been paid. In the event of a transfer of 
ownership of Daig Common Stock that is not registered in the transfer records 
of Daig, a certificate representing the proper number of shares of SJM Common 
Stock may be issued to a transferee if the Certificate representing such Daig 
Common Stock is presented to the Exchange Agent, accompanied by all documents 
required to evidence and effect such transfer and by evidence that any 
applicable stock transfer taxes have been paid. See "CERTAIN PROVISIONS OF 
THE MERGER AGREEMENT -- EXCHANGE PROCEDURES." 

PLEASE DO NOT SEND ANY CERTIFICATES REPRESENTING SHARES OF DAIG COMMON STOCK 
UNTIL YOU RECEIVE THESE MATERIALS. 

CONFLICTS OF INTEREST 

In considering the recommendation of the Daig Board with respect to the 
Merger Agreement, holders of Daig Common Stock should be aware that certain 
members of Daig's management and its Board of Directors have interests in the 
Merger that are in addition to, and different from, the interests of Daig 
shareholders generally. 

SHAREHOLDERS' AGREEMENT. Mr. Fleischhacker, Daig's Chairman of the Board, 
Chief Executive Officer and a director of Daig, and Mr. Starks, Daig's 
President and a director of Daig, have entered into a Shareholders' 
Agreement, dated January 29, 1996, with SJM. Under the terms of the 
Shareholders' Agreement, which is attached as Exhibit B to this Proxy 
Statement/Prospectus and incorporated herein by reference, Mr. Fleischhacker 
and Mr. Starks are required to vote certain of their shares of Daig Common 
Stock, equal to approximately 20% of the outstanding shares of Daig Common 
Stock, in favor of the Merger and the Merger Agreement and against certain 
other actions. Messrs. Fleischhacker and Starks have further agreed to 
certain other restrictions, including a restriction on the sale, pledge or 
other transfer of the shares subject to the Shareholders' Agreement other 
than pursuant to the terms of the Merger Agreement. Each of Mr. Fleischhacker 
and Mr. Starks has executed an irrevocable proxy in connection with the 
Shareholders' Agreement, appointing each of Mr. Matricaria, SJM's President 
and Chief Executive Officer, and Kevin T. O'Malley, SJM's Vice President and 
General Counsel, as proxy with power to vote the shares subject to the 
Shareholders' Agreement in the manner described in the Shareholders' 
Agreement. 

In addition, Daig expects that the directors and executive officers of Daig, 
including Mr. Fleischhacker and Mr. Starks, will vote all of the 8,370,800 
shares of Daig Common Stock they beneficially own at the Record Date 
(approximately 54.9% of the total number of outstanding shares of Daig Common 
Stock at such date) for approval of the Merger Agreement. To the extent that 
such directors and executive officers vote in accordance with Daig's 
expectation, approval of the Merger Agreement is assured. 

DESIGNATED DIRECTOR. It is a condition to Daig's obligation to consummate the 
Merger that Mr. Starks shall have been appointed to fill a newly created 
directorship on the SJM Board having a term expiring at the SJM annual 
meeting of shareholders to be held in 1997. See "CERTAIN PROVISIONS OF THE 
MERGER AGREEMENT -- CONSUMMATION OF THE MERGER." 

EMPLOYMENT AGREEMENTS. Each of Mr. Fleischhacker and Mr. Starks has entered 
into an employment agreement with Daig that will become effective at the 
Effective Time. The employment agreements provide that Messrs. Fleischhacker 
and Starks will be employed as Chairman and Chief Executive Officer and 
President and Chief Operating Officer, respectively. These agreements, which 
have a term of two years each, set the annual base salary for each individual 
($300,000 for Mr. Fleischhacker and $250,000 for Mr. Starks), provide that 
each individual shall be eligible to participate in SJM's bonus, stock option 
and benefits programs, and contain certain provisions regarding confidential 
information, assignment of inventions, non-competition and non-solicitation. 
In addition, each of Mr. Fleischhacker and Mr. Starks has entered into an 
agreement with SJM, similar to the agreements currently provided to SJM 
executives, with regard to the treatment to be accorded such executives upon 
the occurrence of certain events that result in a "change in control" (as 
defined in such agreements) of SJM. SJM has entered into employment 
agreements with substantially all of its executive officers. In the event of 
any "change in control" as defined in the agreements and for a period of 
three years thereafter, if an officer's employment is terminated (i) by SJM 
for reasons other than death, retirement, disability or "cause," or (ii) or 
the officer for "good reason," then SJM shall pay a severance payment, 
generally equal to two times the prior twelve months' compensation if the 
officer's employment with SJM has exceeded three years and one times the 
prior twelve months' compensation if such employment was less than three 
years. "Cause" means conviction by a court of competent authority for felony 
criminal conduct. "Good reason" means substantial and material reduction of 
principal duties, responsibilities and reporting obligations or a reduction 
in annual compensation. In general, a change in control occurs when there has 
been any change in the controlling persons reported in the Company's proxy 
statements, when 40% or more of the Company's outstanding voting stock is 
acquired by any person, or when current members of the Board of Directors or 
their successors elected or nominated by such members cease to be a majority 
of the Board of Directors. 

Mr. Heinmiller, Daig's Vice President -- Finance and Administration, has 
entered into an employment agreement with Daig having a term of one year from 
the Effective Time of the Merger, unless earlier terminated. The agreement 
provides that Mr. Heinmiller will be employed as Daig's Vice President -- 
Finance and Administration at a base salary of $137,000 per annum together 
with a guaranteed annual bonus equal to 30% of this base salary, will receive 
an option to purchase 4,500 shares of SJM Common Stock at the fair market 
value on the date of grant (the "Stock Option"), will have the right to 
participate in SJM's benefit programs and will be subject to certain 
provisions regarding confidential information, assignment of inventions, 
non-competition and non-solicitation. The Stock Option will vest at the rate 
of 25% per year over a period of four years provided Mr. Heinmiller remains 
continuously employed by Daig. If the employment agreement terminates under 
conditions other than those certain ones specifically described in the 
agreement, Mr. Heinmiller will be entitled to receive a bonus payment of 
$322,000. If the payment is not made and Mr. Heinmiller is not employed by 
Daig or an affiliate within one year after expiration of the term of the 
employment agreement, Mr. Heinmiller will be entitled to a bonus payment of 
$20,833.33 per month for each month in the one-year period following the 
expiration of the employment agreement in which he is not employed by Daig or 
an affiliate. In addition, SJM has agreed to allow a $440,000 interest-free 
loan from Daig to Mr. Heinmiller to remain outstanding after the Effective 
Time. SJM has also agreed with Mr. Heinmiller that, in the event the Daig 
Option has not been exercised prior to the Closing Date, SJM will file an 
amendment to a registration statement covering shares of its stock to permit 
Mr. Heinmiller to exercise the option and receive registered shares of SJM 
Common Stock. 

EMPLOYEE BENEFITS. The Merger Agreement provides that following the Effective 
Time, SJM will provide benefits to Daig's employees and officers that are 
comparable to those such employees and officers had prior to the Effective 
Time or comparable to the benefits provided to similarly situated employees 
of SJM and its other subsidiaries and will grant all such employees and 
officers credit for all service with Daig prior to the Effective Time for all 
purposes. SJM has agreed to provide employees and officers (other than 
Messrs. Fleischhacker, Starks and Heinmiller, whose compensation is covered 
by their employment agreements) comparable compensation, taken as a whole, to 
the compensation such employees received prior to the Effective Time. 

INDEMNIFICATION; INSURANCE AND INDEMNIFICATION AGREEMENTS. Under the Merger 
Agreement, SJM has agreed to cause the Surviving Corporation, for the 
six-year period following the Effective Time, to indemnify the present and 
former officers and directors of Daig for acts or omissions occurring prior 
to the Effective Time to the extent provided under Daig's Articles of 
Incorporation and Bylaws, and indemnification agreements between Daig and 
such persons in effect on January 29, 1996. The Merger Agreement also 
provides that SJM and the Surviving Corporation will enter into 
indemnification agreements similar to those indemnification agreements 
currently provided to SJM executives and directors with those Daig employees 
and officers holding positions comparable to the SJM recipients of the SJM 
indemnification agreements. The indemnification agreements that SJM has 
entered into with each of its directors and officers provide for 
indemnification against certain costs incurred by each director and officer 
made or threatened to be made a party to a proceeding because of his or her 
official capacity as a director or officer. Such indemnification agreements, 
together with SJM's Bylaws, provide for indemnification to the full extent 
permitted by Minnesota law. 

                  CERTAIN PROVISIONS OF THE MERGER AGREEMENT 

The following is a summary of the material provisions of the Merger Agreement 
not summarized elsewhere in this Proxy Statement/Prospectus. The following 
summary does not purport to be complete and is qualified in its entirety by 
reference to the Merger Agreement, a copy of which is attached as Exhibit A 
to this Proxy Statement/Prospectus and is incorporated herein by reference. 
All Daig shareholders are urged to read the Merger Agreement and the other 
Exhibits hereto in their entirety. 

CONVERSION OF SECURITIES 

At the Effective Time, by virtue of the Merger and without any action on the 
part of Merger Subsidiary, Daig or the holders of any of the following 
securities, each share of Daig Common Stock outstanding immediately prior to 
the Effective Time (other than (i) any shares of Daig Common Stock owned by 
SJM, Merger Subsidiary or Daig, which will be canceled and retired without 
any conversion or the payment or delivery of any consideration; (ii) 
fractional shares; and (iii) shares for which dissenters' rights have been 
perfected) shall be canceled and converted into the right to receive .651733 
of a share (the "Conversion Ratio") of SJM Common Stock. 

Each share of Common Stock of Merger Subsidiary outstanding immediately prior 
to the Effective Time shall be converted into one validly issued, fully paid 
and nonassessable share of common stock of the Surviving Corporation. Each 
such share shall be owned by SJM. 

EXCHANGE PROCEDURES 

After the Effective Time, each holder of an outstanding certificate or 
certificates theretofore representing shares of Daig Common Stock 
("Certificates"), upon surrender thereof to American Stock Transfer & Trust 
Company or such other banking institution as may be designated by SJM (the 
"Exchange Agent"), will be entitled to receive in exchange therefor a 
certificate representing that number of whole shares of SJM Common Stock into 
which the shares of Daig Common Stock formerly represented by such 
Certificate shall have been converted, together with cash in lieu of any 
fractional share of SJM Common Stock to which such holder is entitled (after 
aggregating all fractional shares of SJM Common Stock to be received by the 
holder) and the amount, without interest, of any dividends or other 
distributions to which such holder is entitled which have become payable with 
respect to such whole number of shares of SJM Common Stock and which have not 
previously been paid. Until surrendered as described herein, each Certificate 
will be deemed at any time after the Effective Time to represent only the 
right to receive upon such surrender the number of whole shares of SJM Common 
Stock into which the shares of Daig Common Stock theretofore represented 
thereby shall have been converted together with cash in lieu of any 
fractional share of SJM Common Stock to which such holder is entitled and any 
dividends or other distributions to which such holder is entitled. Until so 
surrendered, SJM may, at its option, refuse to pay any dividend or other 
distribution payable to holders of SJM Common Stock. 

Any shares of SJM Common Stock deposited with the Exchange Agent that remain 
unclaimed twelve months after the Effective Time shall be returned to SJM 
upon demand. Thereafter, the holder of a Certificate who has not exchanged 
such Certificate prior to such time will be able to look only to SJM for any 
claim for shares of SJM Common Stock, cash in lieu of fractional shares and 
any distributions or dividends. SJM shall not be liable to any holder of SJM 
Common Stock for any amounts paid to a public official pursuant to applicable 
abandoned property laws. See "THE MERGER -- CERTAIN EXCHANGE PROCEDURES." 

NO FURTHER RIGHTS IN DAIG COMMON STOCK 

Whether or not a Certificate is surrendered, from and after the Effective 
Time it shall under no circumstances evidence, represent or otherwise 
constitute any stock or other interest whatsoever in Daig, the Surviving 
Corporation or any other person, firm or corporation other than SJM and SJM's 
successors. 

NO FRACTIONAL SHARES 

No fraction of a share of SJM Common Stock will be issued upon the surrender 
for exchange of Certificates, but in lieu thereof, each holder of shares of 
Daig Common Stock will be entitled to receive an amount in cash equal to the 
product obtained by multiplying (i) such fractional share (after aggregating 
all fractional shares of SJM Common Stock to be received by such holder) by 
(ii) the Reference Market Value. For purposes of the Merger Agreement, the 
Reference Market Value of SJM Common Stock shall mean the average of the 
closing sale prices (in thousandths) on Nasdaq of SJM Common Stock as 
reported in THE WALL STREET JOURNAL for the 20 trading days immediately 
preceding the fifth trading day prior to the Effective Time. 

DAIG STOCK OPTION 

On execution of the Merger Agreement, the Daig Option became exercisable in 
accordance with its terms. At the Effective Time, the Daig Option, an option 
to purchase 128,000 shares of Daig Common Stock held by Mr. Heinmiller, an 
officer and director of Daig, shall, if then unexercised, by virtue of the 
Merger and without any further action on the part of Daig or the holder 
thereof, be assumed by SJM and shall be exercisable upon the same terms and 
conditions as under the Daig Option prior to the Effective Time, except that 
it shall be exercisable for that whole number of shares of SJM Common Stock 
into which the number of shares of Daig Common Stock subject to the Daig 
Option immediately prior to the Effective Time would have been converted 
pursuant to the Merger, at a price per share of SJM Common Stock equal to the 
per share Daig Option exercise price divided by the Conversion Ratio. The 
Daig Option will terminate 30 days after the Effective Time. SJM has agreed 
that, if the Daig Option has not been exercised prior to the Closing Date, 
SJM will file an amendment to a registration statement covering shares of its 
stock to permit the shares of SJM Common Stock issuable upon exercise of the 
Daig Option to be sold to the public following such exercise. 

CERTAIN REPRESENTATIONS AND WARRANTIES 

The Merger Agreement contains various representations and warranties of SJM, 
Merger Subsidiary and Daig relating to, among other things, the following

In the Merger Agreement, SJM and Daig have also mutually agreed to take 
certain actions relating to the preparation and distribution of this Proxy 
Statement/Prospectus and compliance with federal and state securities and 
other laws. 

NO SOLICITATION OF TRANSACTIONS 

Pursuant to the Merger Agreement, Daig has agreed that it will not, and shall 
direct and use its reasonable efforts to cause its officers, directors, 
employees, agents and representatives (including, without limitation, any 
investment banker, attorney or accountant retained by it) not to, directly or 
indirectly, (i) take any further action to solicit, initiate or encourage any 
offer or indication of interest from any person with respect to any 
Acquisition Proposal (as defined below), including without limitation, any 
such further action through any investment banker, broker, finder or other 
intermediary previously engaged or which may be engaged for the purpose of 
soliciting, initiating or encouraging such offer or indication of interest; 
or (ii) engage in negotiations with, or disclose any non-public information 
relating to Daig's businesses, assets or operations or afford access to its 
properties, books or records to, any person that has made, or that Daig has 
good reason to believe may be considering making, an Acquisition Proposal. 
Subject to the fiduciary duties of the Daig Board, Daig (i) will promptly 
notify SJM after receipt of any Acquisition Proposal or indication, in 
writing, that any person is considering making an Acquisition Proposal and 
will keep SJM reasonably informed of any such offer or indication; and (ii) 
will not enter into any agreement relating to any such Acquisition Proposal 
for a period of seven days following receipt by SJM of such notification by 
Daig. 

"Acquisition Proposal" means any proposal to (i) effect a merger or 
consolidation or similar transaction involving Daig or any of its 
subsidiaries; (ii) purchase, lease, or otherwise acquire 10% or more of the 
assets of Daig or any of its subsidiaries; (iii) purchase or otherwise 
acquire (including by way of merger, consolidation, share exchange or similar 
transaction) beneficial ownership (as defined in Rule 13d-3 under the 
Exchange Act) of securities representing 10% or more of the voting power of 
Daig or any of its subsidiaries; or (iv) the assignment, transfer, licensing 
or other disposition of, in whole or in part, the patents, patent rights, 
trade secrets or other technology of Daig or any of its subsidiaries, other 
than in the ordinary course of business. In the event Daig takes action or 
fails to take action required under the exclusivity provisions of the Merger 
Agreement due to a belief that to do otherwise would result in a breach of 
the fiduciary duties of its Board of Directors, it may do so only after 
receipt of a written opinion of its legal counsel or upon advice of its legal 
counsel confirmed by a written opinion of such counsel, and a copy of such 
opinion must be furnished to SJM.

representations or warranties made as of a particular date need only be true 
and correct as of such date), except for any inaccuracies which, individually 
or in the aggregate, have not had, and would not have, a material adverse 
effect; provided, however, that there shall be deemed not to be such a 
material adverse effect to the extent that such effect is the result of 
conditions or factors affecting the economy generally or the industry in 
which SJM operates or the result of the announcement of the Merger or actions 
taken in contemplation thereof; (iii) receipt by Daig of a certificate signed

                   CONDENSED COMBINED FINANCIAL STATEMENTS 

The following Unaudited Pro Forma Condensed Combined Balance Sheet as of 
December 31, 1995, and the related Unaudited Pro Forma Condensed Combined 
Statements of Income for each of the three years in the period ended December 
31, 1995, give effect to the Merger as if it had occurred on the first day of 
the earliest period presented. In addition, the Unaudited Pro Forma Condensed 
Combined Statement of Income for the year ended December 31, 1994 includes 
the results of the Pacesetter acquisition as if it had occurred as of the 
beginning of 1994. The acquisition of Pacesetter was effective September 30, 
1994, and was accounted for as a purchase. The historical SJM results include 
the results of Pacesetter only from October 1, 1994 to December 31, 1994. 
This pro forma information has been prepared utilizing the historical 
consolidated financial statements of SJM and Daig, and should be read in 
conjunction with the historical financial statements and notes thereto, which 
are incorporated by reference herein. Daig's fiscal year ends on September 30 
each calendar year; therefore, Daig's results for the fiscal years ended 
September 30, 1995, 1994 and 1993, have been combined with SJM's results for 
the years ended December 31, 1995, 1994 and 1993. It is anticipated that, 
upon consummation of the Merger, the fiscal year end of Daig will be changed 
to the Saturday closest to December 31. These unaudited pro forma condensed 
combined financial statements are presented for illustrative purposes only 
and are not necessarily indicative of the operating results or financial 
position that would have occurred if the Merger had been consummated, nor are 
they necessarily indicative of future operating results or financial 
position. 

These unaudited pro forma condensed combined financial statements are based 
on the pooling of interests method of accounting for the Merger. The pro 
forma adjustments are described in the accompanying notes.

(a) To reflect the combined tax position as if the Merger had occurred at the 
    beginning of the earliest period presented. This adjustment is based on 
    the evaluation of a variety of factors including the combined companies' 
    statutory and state tax rates, reductions to research and development tax 
    credits and reductions to net operating loss carryforwards. 

(b) To record the exchange of Daig Common Stock for SJM Common Stock. 

(c) To adjust the pro forma condensed combined balance sheet to reflect 
    one-time merger-related charges which will be expensed at the time the 
    merger is consummated as required under the "pooling of interests" 
    accounting method. These charges are presently estimated to be 
    approximately $5.5 million. Direct merger expenses include financial 
    advisor fees, outside legal and accounting fees, and various other costs 
    and filing fees.

                         NOTES TO UNAUDITED PRO FORMA 
                   CONDENSED COMBINED STATEMENTS OF INCOME 

(a) Reflects the combined tax position as if the Merger had occurred at the 
    beginning of the earliest period presented. This adjustment is based on 
    the evaluation of a variety of factors including the combined companies' 
    statutory and state tax rates, reductions to research and development tax 
    credits and reductions to net operating loss carryforwards. 

(b) Represents the results of Pacesetter for the nine months ended September 
    30, 1994, as if the acquisition had been consummated as of the beginning 
    of 1994. SJM's historical results include Pacesetter only from October 1, 
    1994 to December 31, 1994. 

(c) To reflect the Pacesetter acquisition as if the transaction had occurred 
    at the beginning of the year. These adjustments include the elimination 
    of intercompany sales and cost of sales between the U.S. and non-U.S. 
    Pacesetter entities; the ongoing infrastructure costs related principally 
    to the establishment of sales offices in Western Europe; the amortization 
    expense related to the excess cost over net assets acquired; the lost 
    interest income on the cash used to fund a portion of the acquisition; 
    the interest expense on the average debt balance; and the increase in the 
    effective tax rate by 1.5 percentage points. 

(d) The accompanying Unaudited Pro Forma Condensed Combined Statements of 
    Income exclude any merger-related direct expenses. A one-time charge 
    associated with the Merger of approximately $5.5 million is expected to 
    be recognized in the first quarter of 1996. See footnote (c) to the 
    Unaudited Pro Forma Condensed Combined Balance Sheet for additional 
    description of the components of this charge. 

             MATERIAL DIFFERENCES IN RIGHTS OF DAIG SHAREHOLDERS 

GENERAL 

The rights of holders of Daig Common Stock are governed by the Articles of 
Incorporation of Daig (the "Daig Articles"), the bylaws of Daig (the "Daig 
Bylaws") and laws of the State of Minnesota (as previously defined, the 
"MBCA"). The rights of holders of SJM Common Stock are governed by the 
Articles of Incorporation of SJM (the "SJM Articles"), the bylaws of SJM (the 
"SJM Bylaws") and the MBCA. After the Merger becomes effective, the rights of 
holder of Daig Common Stock who become SJM shareholders will be governed by 
the SJM Articles, the SJM Bylaws and the MBCA. While it is not practical to 
describe all changes in the rights of Daig shareholders that will result from 
the differences between the Daig Articles and Bylaws on the one hand and the 
SJM Articles and Bylaws on the other hand, the following is a summary of 
material differences. 

SIZE AND CLASSIFICATION OF THE BOARD OF DIRECTORS 

The MBCA provides that the board of directors of a Minnesota corporation 
shall consist of one or more directors as fixed by the articles of 
incorporation or bylaws. The SJM Bylaws provide that the SJM Board shall 
consist of five directors, and the Board may increase the number of directors 
without shareholder approval. SJM currently has nine directors. Pursuant to 
the SJM Articles and as allowed by the MBCA, SJM's Board of Directors is 
divided into three classes of directors, each director serving a three-year 
term. Each year only one class of directors is subject to a shareholder vote. 

The Daig Bylaws provide that the Daig Board shall consist of six directors, 
subject to increase or decrease by a vote of the holders of a majority of the 
shares entitled to vote at any meeting of the shareholders; the Daig Articles 
provide that the directors may not make, alter or repeal any Bylaw fixing the 
number, qualifications or term in office of any director. All six directors 
of Daig are of one class and are elected every year. 

The MBCA provides that, unless modified by the articles of incorporation or 
bylaws of the corporation or by shareholder agreement, the directors may be 
removed with or without cause by the affirmative vote of that proportion or 
number of the voting power of the shares of the classes or series the 
director represents which would be sufficient to elect such director. The SJM 
Articles provide that any director may be removed from office at any time, 
but only for cause and only by the affirmative vote of at least 80% of the 
votes entitled to be cast by holders of all the outstanding shares of voting 
stock of SJM voting together as a single class. 

The Daig Bylaws provide that directors may be removed as provided by statute. 

SPECIAL MEETINGS OF SHAREHOLDERS 

The SJM Bylaws provide that special shareholders' meetings may be called at 
any time by the Chief Executive Officer or Chief Financial Officer, or by the 
President or Secretary upon the request in writing of two or more directors 
or upon the request in writing of shareholders holding 10% or more of the 
total outstanding shares of SJM Common Stock. 

The Daig Bylaws provide that the Secretary shall call a special meeting of 
the shareholders upon the request of the Chief Executive Officer, the 
President, any two of the members of the Daig Board or upon a written request 
of shareholders holding 10% or more of the voting power of all shares 
entitled to vote, except that a special meeting for the purpose of 
considering any action to facilitate or effect, directly or indirectly, a 
business combination, including any action to change or otherwise affect the 
composition of the Daig Board for that purpose, must be called by 
shareholders holding 25% or more of the voting power of all shares entitled 
to vote. 

AMENDMENT OF CHARTER DOCUMENTS 

The MBCA provides that a resolution proposing an amendment to a corporation's 
articles of incorporation will be submitted to shareholders for approval 
after either being approved by the affirmative vote of the directors or being 
proposed by shareholders holding 3% or more of the voting shares entitled to 
vote thereon. Under the MBCA, any such amendment must be approved by the 
affirmative vote of the holders of a majority of the shares entitled to vote 
thereon, unless the articles of incorporation provide for a number larger 
than a majority. The SJM Articles provide that the affirmative vote of the 
holders of a majority of the outstanding shares of capital stock entitled to 
vote is required to amend provisions of the SJM Articles, provided, however, 
that the affirmative vote of 80% of the votes entitled to be cast by the 
holders of the outstanding shares shall be required to amend or repeal, or 
adopt any provision inconsistent with Articles IX and XIII, which relate to 
management and additional powers and to business combinations, respectively. 

The Daig Articles provide that they may be amended solely by the affirmative 
vote of the holders of a majority of the shares entitled to vote. 

Under the MBCA, shareholders holding 3% or more of the voting power of the 
outstanding shares may propose a resolution to adopt, amend or repeal the 
bylaws adopted, amended or repealed by the board, which resolution must be 
approved by the affirmative vote of the holders of a majority of the shares 
entitled to vote thereon. The SJM Bylaws provide that the SJM Board may alter 
or amend its Bylaws or adopt additional Bylaws, subject to the power of the 
shareholders to change or repeal the Bylaws, except that the SJM Board shall 
not make or alter any Bylaws fixing their qualifications, classifications or 
term of office, or reducing their number. 

The Daig Bylaws provide that the Daig Board may make, alter or repeal Bylaws, 
but only upon a vote of a majority of the entire Daig Board present at any 
meeting called for that purpose, provided that notice of the proposed 
amendment shall have been given to the directors in the notice of such 
meeting. The Daig Articles provide that the directors may not make, alter or 
repeal any Bylaw fixing the number, qualifications or term in office of any 
director. The Daig Board's authority to make, alter or repeal Bylaws is 
subject to the powers of the shareholders to enact, change or repeal Bylaws 
by majority vote of the shareholders present and represented at any meeting 
of the shareholders. 

BUSINESS COMBINATIONS 

The MBCA restricts certain business combination transactions with an 
interested shareholder for four years after such shareholder has acquired 10% 
of the voting power of a publicly traded corporation having 50 or more 
shareholders. The restrictions on business combinations do not apply if the 
business combination or the acquisition of shares in which the 10% ownership 
level was exceeded is approved before the date of such share acquisition by a 
committee of the board of the public corporation. Although permitted by the 
MBCA, SJM has not elected to opt out of the business combination statute. 

Daig has elected in the Daig Bylaws to opt out of the business combination 
rules of the MBCA. 

Article XIII of the SJM Articles includes a "fair price" provision which will 
make it more difficult for a person to stage a "two-tier" acquisition of SJM 
if the second tier of the acquisition is at a lower price than the first 
tier. A 75% shareholder vote is required to approve such a two-tier merger if 
it is not approved by a majority of the continuing directors. Article XIII is 
an attempt to assure that shareholders participating in the second "tier" 
will receive either the same price as received in the first-tier acquisition 
or a minimum price as determined under the formula contained in the fair 
price provision. The Daig Articles have no comparable provision. 

SHAREHOLDERS' RIGHTS PLAN 

SJM is a party to a shareholders' rights agreement which could in certain 
circumstances serve as a deterrent against a possible change of control not 
approved by the SJM Board. Under the agreement, upon the occurrence of 
certain events which result in a change of control as defined by the 
agreement, registered holders of shares of SJM Common Stock are entitled to 
purchase one-tenth of a share of Series A Junior Participating Preferred 
Stock at a stated price, or to purchase shares of capital stock in either SJM 
or the acquiring entity at half their market value. 

Daig has not adopted any comparable shareholders' rights plan. 

                       DISSENTING SHAREHOLDERS' RIGHTS 

Sections 302A.471 and 302A.473 of the MBCA provide shareholders in a 
Minnesota corporation with the right to dissent in the event of a merger and 
obtain payment in cash of the "fair value" (as defined in the statute) of 
their shares. FAILURE TO COMPLY PROPERLY, FULLY AND IN A TIMELY FASHION WITH 
THE STATUTORY REQUIREMENTS WILL RESULT IN THE LOSS OF DISSENTERS' RIGHTS, AND 
ANY DAIG SHAREHOLDER WHO WISHES TO EXERCISE SUCH RIGHTS OR WHO WISHES TO 
PRESERVE THE RIGHT TO DO SO SHOULD CAREFULLY REVIEW THE FOLLOWING DISCUSSION 
AND THE FULL TEXT OF SECTIONS 302A.471 AND 302A.473 OF THE MBCA, WHICH ARE 
ATTACHED TO THIS PROXY STATEMENT/PROSPECTUS AS EXHIBIT D. ANY SUCH 
SHAREHOLDER SHOULD ALSO CONSULT WITH SUCH SHAREHOLDER'S LEGAL COUNSEL. The 
following discussion is not a complete statement of the law pertaining to 
dissenters' rights under the MBCA and is qualified in its entirety by 
reference to the full text of Sections 302A.471 and 302A.473, which are 
attached hereto as Exhibit D. 

PROCEDURE TO PRESERVE DISSENTERS' RIGHTS 

Any Daig shareholder who wishes to exercise dissenters' rights (a) must file 
with Daig, before the vote on the Merger, a written notice of intent to 
demand the fair value of the shares owned by such shareholder if the Merger 
is approved and (b) must not vote his or her shares in favor of the Merger. 
Any such notice must be filed at Daig's executive offices at 14901 DeVeau 
Place, Minnetonka, Minnesota 55345, Attn: Secretary. A vote against the 
Merger does not in itself constitute the written notice required in (a) 
above. A shareholder must satisfy the requirement in (b) above by voting his 
or her shares against the approval of the Merger in person or by proxy or by 
abstaining from voting his or her shares. 

A shareholder may not assert dissenters' rights as to less than all of the 
shares registered in the name of that shareholder. A shareholder may, 
however, dissent with respect to shares registered in the name of that 
shareholder but owned beneficially by someone else if the shareholder (a) 
dissents with respect to all the shares that are beneficially owned by such 
other person and (b) discloses the name and address of each beneficial owner 
on whose behalf the shareholder dissents. Similarly, a beneficial owner of 
shares who is not the shareholder of record may assert dissenters' rights 
with respect to all shares held on behalf of such beneficial owner (and will 
be treated as a dissenting shareholder under the terms of Sections 302A.471 
and 302A.473); to do so, the beneficial owner must submit to Daig, 
concurrently with or prior to asserting such rights, a written consent of the 
record shareholder holding such beneficial owner's shares. The rights of a 
dissenting beneficial owner and a non-dissenting registered owner will be 
determined as if the shares were registered in the names of different 
shareholders. 

If the Merger is approved by the requisite shareholder vote, Daig must send a 
written notice to all shareholders who have filed a written notice of intent 
to demand payment and have refrained from voting in favor of approving the 
Merger. The notice from Daig must contain: 

(1) the address to which a demand for payment and stock certificates must be 
    sent in order to obtain payment and the date by which they must be 
    received; 

(2) a form to be completed by the shareholder to demand payment and to 
    certify the date on which the shareholder, or the beneficial owner on 
    whose behalf the shareholder dissents, acquired the shares or an interest 
    in them; and 

(3) copies of Sections 302A.471 and 302A.473 and a brief description of the 
    procedures to be followed under such sections. 

To receive the fair value of the shares, a dissenting shareholder must demand 
payment and deposit his or her shares within 30 days after the notice is 
mailed by Daig. A dissenter retains all other rights of a shareholder until 
the Effective Time. 

PROCEDURES FOLLOWING AN ASSERTION OF DISSENTERS' RIGHTS 

After the Effective Time, or after the Surviving Corporation receives a valid 
demand for payment, whichever is later, the Surviving Corporation must remit 
to each such validly demanding shareholder the amount that the Surviving 
Corporation estimates to be the fair value of the shares, plus any interest 
that may have accrued. (Interest accrues from five days after the Effective 
Time up to and including the date of payment at the rate provided under 
Minnesota law for interest on verdicts and judgments). The Surviving 
Corporation shall include with this payment: 

(1) certain financial statements of the Surviving Corporation; 

(2) an estimate of the fair value of the shares and a brief description of 
    the method used to reach the estimate; and 

(3) a copy of Sections 302A.471 and 302A.473 and a brief description of the 
    procedure to be followed in demanding supplemental payment under such 
    sections. 

The term "fair value" under Section 302A.473 means the value of the shares 
immediately before the Effective Time. 

If the Surviving Corporation fails to remit payment within 60 days of the 
deposit of stock certificates, it must return all deposited certificates. 
However, the Surviving Corporation may require a deposit at a later time and 
again give notice that contains: 

(1) the address to which a demand for payment and stock certificates must be 
    sent in order to obtain payment and the date by which they must be 
    received; 

(2) a form to be completed by the shareholder to demand payment and to 
    certify the date on which the shareholder, or the beneficial owner on 
    whose behalf the shareholder dissents, acquired the shares or an interest 
    in them; and 

(3) copies of Sections 302A.471 and 302A.473 and a brief description of the 
    procedures to be followed under such sections. 

If a dissenter believes that the amount remitted by the Surviving Corporation 
is less than the fair value of his or her shares plus interest, the dissenter 
may, within 30 days of the remittance (or the offer of remittance), give 
written notice to the Surviving Corporation of the dissenter's own estimate 
of the fair value of the shares, plus interest, and demand payment of the 
difference (a "Demand"). If a dissenter does not do so, that dissenter is 
entitled only to the amount remitted (or offered) by the Surviving 
Corporation. 

If the Surviving Corporation receives a Demand, it must, within 60 days after 
receiving the Demand, either pay to the dissenter the amount demanded or 
agreed to by the dissenter after discussion with the Surviving Corporation or 
file in the appropriate Minnesota state court a petition requesting that the 
court determine the fair value of the shares, plus interest. The petition 
must name as parties all dissenters who made a Demand and who have not 
reached agreement with the Surviving Corporation. The court must determine 
whether the dissenter or dissenters in question have fully complied with all 
statutory requirements and must determine the fair value of the shares, 
taking into account any and all factors the court finds relevant, computed by 
any method or combination of methods that the court, in its discretion, sees 
fit to use, whether or not used by the Surviving Corporation or by a 
dissenter. The court may appoint appraisers, with powers and authorities the 
court deems proper, to receive evidence on and recommend the amount of the 
fair value of the shares. The fair value of the shares as determined by the 
court is binding on all shareholders, wherever located. A dissenter is 
entitled to judgment for the amount, if any, by which the fair value of the 
shares as determined by the court, plus interest, exceeds the amount, if any, 
remitted by the Surviving Corporation, but shall not be liable to the 
Surviving Corporation for the amount, if any, by which the amount, if any, 
remitted to the dissenter exceeds the fair value of the shares as determined 
by the court, plus interest. 

The court must determine the costs and expenses of any proceeding, including 
the reasonable expenses and compensation of any appraisers appointed by the 
court, and must assess those costs and expenses against the Surviving 
Corporation, except that the court may assess part or all of those costs and 
expenses against a dissenter whose Demand is found to be arbitrary, vexatious 
or not in good faith. If the court finds that the Surviving Corporation has 
failed to comply substantially with the statutory requirements, the court may 
assess against the Surviving Corporation all fees and expenses of any experts 
or attorneys as the court deems equitable. In addition, fees and expenses may 
be assessed against any dissenter who has acted arbitrarily, vexatiously or 
not in good faith in bringing the proceeding. 

The court may, in its discretion, award fees and expenses to an attorney for 
the dissenters out of the amount awarded to the dissenters, if any. 

TAX TREATMENT 

Cash received pursuant to the exercise of dissenters' rights may be subject 
to federal or state income tax. See "THE MERGER -- CERTAIN FEDERAL TAX 
CONSEQUENCES." 

                                LEGAL MATTERS 

The validity of the SJM Common Stock to be issued to the shareholders of Daig 
in connection with the Merger will be passed upon for SJM by Lindquist & 
Vennum P.L.L.P., Minneapolis, Minnesota. Thomas H. Garrett III, a partner of 
Lindquist & Vennum P.L.L.P., is a director and shareholder of SJM. Certain 
federal income tax consequences in connection with the Merger will be passed 
on by Dorsey & Whitney LLP, Minneapolis, Minnesota.

                          AGREEMENT AND PLAN OF MERGER


         THIS AGREEMENT dated January 29, 1996, among Daig Corporation, a
Minnesota corporation ("Partner"), St. Jude Medical, Inc., a Minnesota
corporation ("Company") and Partner Acquisition Corp., a Minnesota corporation
and a wholly owned subsidiary of Company ("Merger Subsidiary").

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

         WHEREAS, in furtherance of such acquisition, the Boards of Directors of
Company, Merger Subsidiary and Partner have each approved the merger of Merger
Subsidiary with and into Partner in accordance with the Minnesota Business
Corporation Act ("Minnesota Law") and upon the terms and subject to the
conditions set forth herein;

         WHEREAS, as a result of the Merger, all of the outstanding common
stock, $.01 par value, of Partner ("Partner Common Stock") will be converted
into the right to receive common stock, $.10 par value, of Company ("Company
Common Stock");

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

         WHEREAS, for accounting purposes, it is intended that the Merger shall 
be accounted for as a "pooling of interests."

         The parties hereto agree as follows:

                                    ARTICLE I
                                   THE MERGER

         SECTION 1.1 THE MERGER.

                  1.1.1 Subject to the terms and conditions of this Agreement,
at the Effective Time (as defined in Section 1.1.2), Merger Subsidiary shall be
merged with and into Partner (the "Merger") in accordance with Minnesota Law,
whereupon the separate existence of Merger Subsidiary shall cease, and Partner
shall continue as the surviving corporation (the "Surviving Corporation") under
the name of Partner as set forth in Section 1.1.3.

                  1.1.2 As soon as practicable after satisfaction of or, to the
extent permitted hereunder, waiver of, all conditions to the Merger set forth in
Article VIII, the parties hereto



                                       A-7



shall cause the Merger to be consummated by filing Articles of Merger (the
"Articles of Merger") with the Secretary of State of the State of Minnesota, in
such form as required by, and executed in accordance with the relevant
provisions of, Minnesota Law and the parties hereto shall make all other filings
or recordings required by Minnesota Law in connection with the Merger and the
transactions contemplated by this Agreement. The Merger shall become effective
at such time as the Articles of Merger are duly filed with the Secretary of
State or such later date set forth in the Articles of Merger (the "Effective
Time").

                  1.1.3 At the Effective Time, (i) the separate existence of
Merger Subsidiary shall cease and Merger Subsidiary shall be merged with and
into Partner, which shall be the Surviving Corporation; (ii) the officers of the
Surviving Corporation shall initially be the officers of Partner immediately
prior to the Merger; (iii) the directors of the Surviving Corporation shall
initially be the directors of Merger Subsidiary immediately prior to the Merger;
(iv) the Articles of Incorporation and Bylaws of the Surviving Corporation shall
initially be the same as the Articles of Incorporation and Bylaws, respectively,
of Merger Subsidiary immediately prior to the Merger, except that Article I of
the Articles of Incorporation of Merger Subsidiary shall, at the Effective Time,
be amended to read that "The name of the Corporation is Daig Corporation;" and
(v) the Merger shall, from and after the Effective Time, have all of the effects
provided by applicable law. Without limiting the generality of the foregoing,
and subject thereto, at the Effective Time all the property, rights, privileges,
powers and franchises of Merger Subsidiary and Partner shall vest in the
Surviving Corporation, and all debts, liabilities and duties of Merger
Subsidiary and Partner shall become the debts, liabilities and duties of the
Surviving Corporation.

         SECTION 1.2 CONVERSION OF MERGER SUBSIDIARY CAPITAL STOCK. At the
Effective Time, each share of capital stock of Merger Subsidiary outstanding
immediately prior to the Effective Time shall be converted into and become one
validly issued, fully paid and non-assessable share of capital stock of the
Surviving Corporation with the same rights and privileges as the shares of
Merger Subsidiary so converted, which share shall be owned by Company.

         SECTION 1.3 CANCELLATION OR CONVERSION OF PARTNER COMMON STOCK. As of
the Effective Time of the Merger, by virtue of the Merger and without any action
on the part of any shareholder:

                  1.3.1 Any shares of Partner Common Stock issued and
outstanding immediately prior to the Effective Time which are owned by Company,
Merger Subsidiary or Partner shall be canceled and retired without any
conversion thereof, and no cash, securities or other consideration shall be paid
or delivered in exchange for such Partner Common Stock.

                  1.3.2 Except (i) as provided herein with respect to Dissenting
Shares (as defined below in Section 1.5); (ii) fractional shares; and (iii)
shares of Partner Common Stock canceled pursuant to Section 1.3.1 hereof, at the
Effective Time, each share of Partner



                                       A-8



Common Stock outstanding shall be canceled and converted into the right to
receive a fraction of a share of Company Common Stock equal to .651733 (the
"Conversion Ratio"), such shares of Company Common Stock, together with the cash
in respect of fractional shares to be received pursuant to Section 1.3.3 (the
"Merger Consideration").

                  1.3.3 No fraction of a share of Company Common Stock will be
issued in the Merger but, in lieu thereof, each holder of shares of Partner
Common Stock who would otherwise be entitled to a fraction of a share of Company
Common Stock (after aggregating all fractional shares of Company Common Stock to
be received by the holder) will be entitled to receive from the Company an
amount of cash (rounded to the nearest whole cent) equal to the product of (i)
such fraction multiplied by (ii) the Reference Market Value. For purposes of
this Agreement, "Reference Market Value" of a share of Company Common Stock
shall mean the average of the closing sale prices (in thousandths) on the NASDAQ
National Market System (the "NASDAQ") of Company Common Stock as reported in The
Wall Street Journal for the twenty trading days immediately preceding the fifth
trading day prior to the Effective Time.

         SECTION 1.4 EXCHANGE OF SHARES.

                  1.4.1 After the Effective Time, each holder of an outstanding
certificate or certificates theretofore representing shares of Partner Common
Stock ("Partner Stock Certificates"), upon surrender thereof to American Stock
Transfer & Trust Company, or such other banking institution as shall be
designated by Company, as exchange agent (the "Exchange Agent"), shall be
entitled to receive the Merger Consideration. Until so surrendered, each
outstanding Partner Stock Certificate shall be deemed for all purposes, other
than as provided below with respect to the payments of dividends or other
distributions, if any, in respect of Company Common Stock, to represent a right
to receive the number of whole shares of Company Common Stock into which the
shares of Partner Common Stock theretofore represented thereby shall have been
converted together with payment for fractional shares. Until so surrendered,
Company may, at its option, refuse to pay any dividend or other distribution, if
any, payable to the holders of shares of Company Common Stock to the holders of
Partner Stock Certificates; provided, however, that upon surrender and exchange
of such Partner Stock Certificates, there shall be paid to the record holders of
the stock certificate or certificates issued in exchange therefor the amount,
without interest, of dividends and other distributions, if any, which have
become payable with respect to the number of whole shares of Company Common
Stock into which the shares of Partner Common Stock theretofore represented
thereby shall have been converted and which have not previously been paid,
together with any payment for fractional shares required by Section 1.3.3
hereof. Whether or not a Partner Stock Certificate is surrendered, from and
after the Effective Time such certificate shall under no circumstances evidence,
represent or otherwise constitute any stock or other interest whatsoever in the
Company, the Surviving Corporation or any other person, firm or corporation
other than Company or its successors.



                                       A-9



                  1.4.2 Any shares of Company Common Stock deposited with the
Exchange Agent that remain unclaimed by the holders of shares of Partner Common
Stock twelve months after the Effective Time shall be returned to Company upon
demand, and any such holder who has not exchanged his shares of Partner Common
Stock for the Merger Consideration prior to that time shall thereafter look only
to Company for his claim for Company Common Stock, any cash in lieu of
fractional shares of Company Common Stock and any dividends or distributions
with respect to Company Common Stock. Notwithstanding the foregoing, Company
shall not be liable to any holder of shares of Company Common Stock for any
amount paid to a public official pursuant to applicable abandoned property laws.

         SECTION 1.5 DISSENTING SHARES.

                  1.5.1 Notwithstanding any provision of this Agreement to the
contrary, any shares of capital stock of Partner held by a holder which has
demanded and perfected its right for appraisal of such shares in accordance with
Minnesota Law (the "Dissenters' Rights") and who, as of the Effective Time, has
not effectively withdrawn or lost such right to appraisal ("Dissenting Shares"),
shall not be converted into or represent a right to receive the Merger
Consideration pursuant to Section 1.3, but the holder thereof shall only be
entitled to such rights as are granted by the Dissenters' Rights.

                  1.5.2 Notwithstanding the provisions of Section 1.5.1, if any
holder of shares of capital stock of Partner who demands appraisal of such
shares under the Dissenters' Rights shall effectively withdraw or lose (through
failure to perfect or otherwise) its right to appraisal, then, as of the later
of the Effective Time or the occurrence of such event, such holder's shares
shall automatically be converted into and represent only the right to receive
the Merger Consideration as provided in Section 1.3, without interest thereon,
upon surrender of the certificate or certificates representing such shares.

                  1.5.3 Partner shall give Company (i) prompt written notice of
any notice of intent to demand fair value for any shares of capital stock of
Partner, withdrawals of such notices, and any other instruments served pursuant
to the Dissenters' Rights and received by Partner; and (ii) the opportunity to
direct and carry on all negotiations and proceedings with respect to demands for
fair value for shares of capital stock of Partner under the Dissenters' Rights.
Partner shall not, except with the prior written consent of Company, voluntarily
make any payment with respect to any demands for fair value for shares of
capital stock of Partner or offer to settle or settle any such demands other
than by operation of law or pursuant to a final order of a court of competent
jurisdiction.

         SECTION 1.6 ADJUSTMENTS. In the event that, subsequent to the date of
this Agreement but prior to the Effective Time, the outstanding shares of
Company Common Stock shall have been increased, decreased, changed into or
exchanged for a different number or kind of shares or securities and such
increase, decrease, change or exchange shall have been effected through a stock
dividend, stock split or reverse stock split, then an appropriate and



                                      A-10



proportionate adjustment shall be made to the Conversion Ratio to fully reflect
such increase, decrease, change or exchange.

         SECTION 1.7 PARTNER OPTION. The non-qualified stock option to purchase
128,000 shares of Partner Common Stock (the "Partner Option"), outstanding on
the date hereof, shall, pursuant to the terms of the Partner Option (i) become
exercisable in accordance with its terms and (ii) terminate 30 days after the
Effective Time. From and after the Effective Time until the end of such 30-day
period, all references to Partner in the Partner Option and the related stock
option agreement shall be deemed to refer to Company. During such period, the
Partner Option shall be assumed by Company and shall be exercisable upon the
same terms and conditions as under the Partner Option and the related option
agreement, except that (i) such Partner Option shall be exercisable for that
whole number of shares of Company Common Stock (to the nearest whole share) into
which the number of shares of Partner Common Stock subject to such Partner
Option immediately prior to the Effective Time would be converted under Section
1.3, and (ii) the option price per share of Company Common Stock shall be an
amount equal to the option price per share of Partner Common Stock subject to
such Partner Option in effect immediately prior to the Effective Time divided by
the Conversion Ratio (the option price per share, as so determined, being
rounded upward to the nearest full cent).


                                   ARTICLE II

                                   ARTICLE III
                    REPRESENTATIONS AND WARRANTIES OF PARTNER

         Partner represents and warrants to Company as follows, except as set
forth in the schedule of exceptions to representations and warranties attached
hereto as Schedule 3 (the "Disclosure Schedule"):



                                      A-11



         SECTION 3.1 CORPORATE EXISTENCE AND POWER.

                  3.1.1 Partner is a corporation duly organized, validly
existing and in good standing under the laws of its jurisdiction of
incorporation, and has all corporate powers required to carry on its business as
now conducted. Partner is duly qualified to do business as a foreign corporation
and is in good standing in each jurisdiction where the character of the property
owned or leased by it or the nature of its activities makes such qualification
necessary, except for those jurisdictions where the failure to be so qualified
would not, individually or in the aggregate, have a Material Adverse Effect.
Partner has heretofore delivered to Company true and complete copies of
Partner's Articles of Incorporation and Bylaws, as currently in effect.

                  3.1.2 For purposes of this Agreement, a "Material Adverse
Effect," when used with respect to any entity, shall mean a material adverse
change in the financial condition, business, assets, liabilities,
capitalization, financial position compared to the financial statements as of
September 30, 1995, in the case of Partner or as of December 31, 1995 in the
case of Company, operations or results of operations of such entity and its
subsidiaries taken as a whole or any event described in Schedule 3.1.2 which
could, so far as can reasonably be foreseen, have such an effect.

         SECTION 3.2 CORPORATE AUTHORIZATION. Partner has the corporate power
and authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby have been duly and
validly authorized by Partner's Board of Directors and no other corporate
proceedings on the part of Partner are necessary to authorize the execution and
delivery of this Agreement or to consummate the transactions so contemplated
(except the approval of this Agreement and the transactions contemplated hereby
by the shareholders of Partner required in accordance with Minnesota Law and the
Articles of Incorporation and Bylaws of Partner).

         SECTION 3.3 SUBSIDIARIES. Schedule 3.3 of the Disclosure Schedule
contains a true and complete list of all of Partner's subsidiaries (each such
subsidiary shall hereinafter separately be called a "Partner Subsidiary" and all
such subsidiaries shall collectively be called the "Partner Subsidiaries") and
their jurisdictions of incorporation. All of the shares of capital stock of each
of the Partner Subsidiaries are owned directly or indirectly by Partner, are
validly issued, fully paid and nonassessable and are owned free and clear of any
Liens. There are no existing options, warrants, calls or commitments of any
character relating to the issued or unissued capital stock of any of the Partner
Subsidiaries. Partner has, and the Partner Subsidiaries have, no material
investment in any subsidiary or any material investment in any partnership,
joint venture or similar entity, all of which investments are owned free and
clear of any Liens. Each of the Partner Subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation.



                                      A-12



         SECTION 3.4 GOVERNMENTAL AUTHORIZATION; CONSENTS.

                  3.4.1 The execution, delivery and performance by Partner of
this Agreement and the consummation of the Merger by Partner require no action
by or in respect of, or filing with, any governmental body, agency, official or
authority other than (i) the filing of Articles of Merger in accordance with
Minnesota Law; (ii) compliance with any applicable requirements of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"); (iii)
compliance with any applicable requirements of the Securities Act of 1933, as
amended, and the rules and regulations promulgated thereunder (the "1933 Act")
and the Securities Exchange Act of 1934, as amended, and the rules and
regulations promulgated thereunder (the "1934 Act"); (iv) compliance with the
rules and regulations of the NASDAQ National Market System; (v) compliance with
any applicable state securities laws; and (vi) any action or filing, the failure
to obtain or make would not, individually or in the aggregate, have a Material
Adverse Effect.

                  3.4.2 No consent, approval, waiver or other action by any
person under any material contract, agreement, indenture, lease, instrument or
other material document to which Partner is a party or by which it is bound is
required or necessary for the execution, delivery and performance of this
Agreement by Partner or the consummation of the transactions contemplated
hereby.

         SECTION 3.5 NON-CONTRAVENTION. The execution, delivery and performance
by Partner of this Agreement do not, and the consummation by Partner of the
transactions contemplated hereby will not (i) contravene or constitute a default
under or give rise to a right of termination, cancellation or acceleration of
any right or obligation of Partner or to a loss of any benefit to which Partner
is entitled under (A) any provision of applicable law or regulation (assuming
compliance with the matters referred to in Section 3.4.1), other than such
contraventions, defaults or rights of termination, cancellation or acceleration
which would not, individually or in the aggregate, have a Material Adverse
Effect; (B) the Articles of Incorporation or Bylaws of Partner; (C) any
agreement, contract, plan, lease, arrangement or commitment, other than such
contraventions, defaults or rights of termination, cancellations or acceleration
which would not, individually or in the aggregate, have a Material Adverse
Effect; or (D) any judgment, injunction, order, decree, administrative
interpretation, award or other instrument binding upon Partner, other than such
contraventions, defaults or rights of termination, cancellations or acceleration
which would not, individually or in the aggregate, have a Material Adverse
Effect, or (ii) result in the creation or imposition of any Lien on any asset of
Partner. For purposes of this Agreement, "Lien" means, with respect to any
asset, any mortgage, lien, pledge, charge, security interest, restriction on
transfer or encumbrance of any kind in respect of such asset; provided, however,
"Lien" does not include liens for taxes or statutory liens, not yet delinquent
or the validity of which is being contested in good faith by appropriate
proceedings.



                                      A-13



         SECTION 3.6 BINDING EFFECT. This Agreement constitutes a valid and
binding agreement of Partner enforceable against Partner in accordance with its
terms, except to the extent that the enforceability thereof may be limited by
applicable bankruptcy, insolvency, reorganization or other similar laws
affecting the enforcement of creditors' rights generally and by principles of
equity regarding the availability of remedies.

         SECTION 3.7 CAPITALIZATION. The authorized capital stock of Partner
consists of 40,000,000 shares of Partner Common Stock. As of the date hereof (i)
15,236,144 shares of Partner Common Stock were outstanding, and (ii) stock
options to purchase an aggregate of 128,000 shares of Partner Common Stock under
the Partner Option were outstanding. All outstanding shares of capital stock of
Partner have been duly authorized and validly issued and are fully paid and
nonassessable. Except for the Partner Option, there are no plans, agreements or
other arrangements pursuant to which any options, warrants or other rights to
acquire shares of capital stock of Partner are outstanding. An aggregate of
128,000 shares of Partner Common Stock have been reserved for issuance under the
Partner Option. Except as set forth in this Section, there are outstanding (i)
no shares of capital stock or other voting securities of Partner, (ii) no
securities of Partner convertible into or exchangeable for shares of capital
stock or voting securities of Partner, and (iii) no options or other rights to
acquire from Partner, and no obligation of Partner to issue, any capital stock,
voting securities or securities convertible into or exchangeable for capital
stock or voting securities of Partner (collectively "Partner Securities"). There
are no outstanding obligations of Partner to repurchase, redeem or otherwise
acquire any Partner Securities.

         SECTION 3.8 FINANCIAL STATEMENTS AND SEC FILINGS. Partner has delivered
to Company true and complete copies of (i) its annual reports on Form 10-K for
its fiscal years ended September 30, 1993, 1994 and 1995; (ii) its quarterly
reports on Form 10-Q for its fiscal quarters commencing October 1, 1993; (iii)
its proxy or information statements relating to all meetings of, or actions
taken without a meeting by, the shareholders of Partner held since September 30,
1993; and (iv) all of its other reports or registration statements filed with
the Securities and Exchange Commission (the "SEC") since October 1, 1993. The
reports and statements so delivered are referred to collectively in this
Agreement as the "Partner SEC Filings." As of their respective dates, the
Partner SEC Filings (including all exhibits and schedules thereto and documents
incorporated by reference therein) did not contain any untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements made, in light of the circumstances under which they were made, not
misleading. Partner has delivered to Company's counsel copies of any statements
on Schedule 13D and Schedule 13G known to Partner which had been filed with the
SEC with respect to capital stock of Partner pursuant to the 1934 Act. The
audited financial statements and unaudited interim financial statements of
Partner included or incorporated by reference in the Partner SEC Filings (i)
have been prepared in accordance with generally accepted accounting principles
(except, in the case of unaudited statements, as permitted by Form 10-Q of the
1934 Act) applied on a consistent basis during the periods involved (except as
may be indicated in the notes thereto); (ii) complied as of their respective
dates in all material respects with



                                      A-14



applicable accounting requirements and the published rules and regulations of
the SEC with respect thereto; and (iii) fairly present the financial position of
Partner as of the dates thereof and the income and cash flows for the periods
then ended (subject, in the case of any unaudited interim financial statements,
to normal year-end adjustments).

         SECTION 3.9 MATERIAL EVENTS. Except as disclosed in the Partner SEC
Filings, and except as expressly contemplated by this Agreement, since the date
of the most recent audited financial statements included in the Partner SEC
Filings there has not been:

                  3.9.1 Any event, occurrence or development of a state of
circumstances or facts which has had a Material Adverse Effect.

                  3.9.2 Any discharge or satisfaction of any Lien, other than
those then required to be discharged or satisfied, or any payment of any
obligation or liability, absolute, accrued, contingent or otherwise, whether due
or to become due, other than the payment of current liabilities shown on the
financial statements and included in the Partner SEC Filings and current
liabilities incurred since the date of the most recent audited financial
statements included in the Partner SEC Filings in the ordinary course of
business and consistent with its prior practice and other than payments which,
individually and in the aggregate, would not exceed $50,000.

                  3.9.3 Any declaration, setting aside or payment of any
dividend or other distribution with respect to any shares of capital stock of
Partner, or any repurchase, redemption or other acquisition by Partner of any
outstanding shares of capital stock or other ownership interests in or other
securities of Partner.

                  3.9.4 Any alteration in any material term of any outstanding
security of Partner.

                  3.9.5 Any damage, destruction or other casualty loss (whether
or not covered by insurance) affecting the business or assets of Partner which,
in the aggregate, has resulted in or might reasonably be expected to result in a
loss in excess of $250,000.

                  3.9.6 Any change in any method of accounting or accounting
practice by Partner, except for any such change required by reason of a
concurrent change in generally accepted accounting principles.

                  3.9.7 Any labor dispute, other than routine individual
grievances, or, to Partner's knowledge, any activity or proceeding by a labor
union or representative thereof to organize any employees of Partner or any
lockouts, strikes, slowdowns, or work stoppages. For purposes of this Agreement,
"knowledge" of a party means, unless otherwise specifically qualified in the
Agreement, the actual knowledge of the officers and directors of that party, as
such knowledge has been obtained in the normal conduct of the business, and also
includes



                                      A-15



such knowledge as a reasonably prudent officer would have obtained upon the
exercise of reasonable diligence under the same or similar circumstances;
"known" or "aware" shall have a correlative meaning.

                  3.9.8 Any transaction or commitment made by Partner relating
to its assets or business (including the acquisition or disposition of any
assets), or any relinquishment of any contract or other right material to
Partner and its subsidiaries taken as a whole, other than transactions and
commitments in the ordinary course of business, those that would not exceed
$100,000, those contemplated by this Agreement or those constituting an
Acquisition Proposal (as defined in Section 5.7).

                  3.9.9 Any (i) incurrence, assumption or guarantee by Partner
of any indebtedness other than in the ordinary course of business in amounts and
on terms consistent with past practices, (ii) issuance or sale of any securities
convertible into or exchangeable for debt securities of Partner, or (iii)
issuance or sale of options or other rights to acquire from Partner, directly or
indirectly, debt securities of Partner or any securities convertible into or
exchangeable for any such debt securities.

                  3.9.10 Any creation or assumption of any Lien by Partner on
any asset of Partner other than in the ordinary course of business.

                  3.9.11 Any grant, except pursuant to agreements in effect on
the date of this Agreement, of any material severance or termination pay to, any
entering into of any employment, deferred compensation or other similar
agreement with, or any increase in benefits payable under any existing severance
or termination pay policies or employment agreements, or any increase in
compensation, bonus or other benefits payable to any current or former
shareholder, officer, director, salesperson, distributor, agent or employee of
Partner, other than any grants or increases in the ordinary course of business
consistent with past practice.

                  3.9.12 Any sale, transfer, lease to others or other
disposition of any material assets of Partner, except for inventory sold in the
ordinary course of business, or any cancellation or compromise of any material
debt or claim, or any waiver or release of any right, other than sales,
transfers, leases, dispositions, cancellations, compromises, waivers or releases
made in the ordinary course of business and which, individually and in the
aggregate, would not have a Material Adverse Effect.

                  3.9.13 Any receipt of a notice of termination of any contract
(including without limitation, any material distributorship agreement) or lease
or other agreement required to be disclosed in Section 3.18 below.

                  3.9.14 Any transfer or grant of any rights under, or any
settlement regarding the breach or infringement of, any United States or foreign
license, patent, copyright,



                                      A-16



trademark, trade name, invention or similar rights, or modified any existing
rights with respect thereto.

                  3.9.15 Any material increase or decrease in the quantity of
items of inventory not consistent with Partner's prior practice, or any purchase
commitment in excess of the normal, ordinary and usual requirements of Partner's
business, or any material change in Partner's selling, pricing or advertising
practices inconsistent with its prior practice.

                  3.9.16 Any written agreement or, to Partner's knowledge, any
commitment to take any of the types of action described in paragraphs 3.9.1
through 3.9.15 above.

         SECTION 3.10 PROPERTIES; LIENS. Partner has good title to all of its
assets material to the business, results of operation or financial condition of
Partner, subject, in each case, only to Liens and imperfections of title and
encumbrances, if any, which, individually or in the aggregate, do not have a
Material Adverse Effect. Schedule 3.10 of the Disclosure Schedule sets forth a
summary description of all real property (including warehouses) leased by
Partner, together with any encumbrances on Partner's interest. The leases,
subleases and other agreements disclosed in Schedule 3.10 of the Disclosure
Schedule are in full force and effect. Partner is not in material default under
any such lease, sublease or agreement and has received no notice of default
thereunder and, to the knowledge of Partner, no other party thereto is in
material default thereunder. Partner enjoys a right of quiet possession as
against any Lien on its real property interests. To Partner's knowledge, all
buildings and other structures leased by Partner are (i) in good operating
condition and repair, normal wear and tear excepted; and (ii) in Partner's
judgment, adequate for the uses to which they are being put. Partner has not
received any notice and has no knowledge of any pending, threatened or
contemplated condemnation proceeding affecting the real property leased by
Partner or any part thereof or of any sale or other disposition of such real
property or any part thereof in lieu of condemnation.

         SECTION 3.11 LITIGATION. As of the date hereof there is no action,
suit, proceeding, or, to the knowledge of Partner, any investigation pending
against, or, to the knowledge of the Partner, overtly threatened against or
affecting, Partner or any of its properties before any court or arbitrator or
any governmental body, agency or official. There are no actions, suits or claims
or legal, administrative or arbitral proceedings pending or, to the knowledge of
Partner, overtly threatened against or affecting, Partner or any of its
properties (other than any such suit, action or proceeding challenging the
acquisition by Company or Merger Subsidiary of the shares of Partner Common
Stock or any provision of this Agreement or seeking to restrain or prohibit the
consummation of the Merger) before any court or arbitrator or any governmental
body, agency or official that, if determined or resolved adversely to Partner
(in accordance with the plaintiff's demands, if applicable), individually or in
the aggregate, would reasonably be expected to have a Material Adverse Effect.



                                      A-17



         SECTION 3.12 TAXES. The statute of limitations for the assessment of
federal income taxes has expired for all federal income tax returns of Partner
or its predecessor through the fiscal year ended September 30, 1992. Partner is
not currently being audited by any tax authority. Partner has filed all material
returns for Taxes, as defined below, that it is required to file. Each of the
federal, state, and local income tax returns heretofore filed by Partner is true
and correct in all material respects. Partner has timely paid or made provision
for all material Taxes that have been shown as due and payable on the returns
that have been filed. The charges, accruals and reserves for taxes reflected in
the financial statements contained in the most recently filed Partner SEC
Filings are adequate to cover the material Tax liabilities accruing or payable
by Partner in respect of periods covered by such financial statements. Partner
is not delinquent in the payment of any Taxes (other than Taxes, the failure to
pay which would not, individually or in the aggregate, result in amounts owing
(including penalties and interest) in excess of $100,000). Partner has not
requested any extension of time within which to file or send any return, which
return has not since been filed or sent. No deficiency for any Taxes has been
proposed, asserted or assessed in writing against Partner and Partner does not
know of any other unassessed Tax deficiency threatened or proposed against
Partner (other than deficiencies, the liability for which would not,
individually or in the aggregate, result in amounts owing (including penalties
and interest) in excess of $100,000). Partner has not been granted any extension
of the limitation period applicable to any Tax claims. Partner is not, nor has
Partner been, a party to any tax sharing agreement with any corporation. "Tax"
means with respect to any person (i) any net income, gross income, gross
receipts, sales, use, ad valorem, franchise, profits, license, withholding,
payroll, employment, excise, severance, stamp, occupation, premium, property or
windfall profit tax, custom duty or other tax, governmental fee, or other like
assessment or charge of any kind whatsoever, together with any interest and any
penalty, addition to tax or additional amount imposed by any taxing authority
(domestic or foreign) on such person; and (ii) any liability of Partner for the
payment of any amount of the type described in the immediately preceding clause
(i) as a result of being a member of an affiliated or combined group, or as a
result of any spin off, distribution or other reorganization related to the
disposition of any assets or business of Partner. Partner has not, for the five
year period preceding the Effective Time, been a United States real property
holding corporation within the meaning of Section 897(c)(2) of the Code.

         SECTION 3.13 ERISA.

                  3.13.1 Schedule 3.13.1 of the Disclosure Schedule lists each
"employee benefit plan," as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974 ("ERISA"), which is or was subject to any provision
of ERISA and with respect to which Partner or any affiliate (as defined below)
has any direct or indirect, fixed or contingent liability as of the Effective
Time. Copies of such plans (and, if applicable, related trust agreements or
insurance contracts) and all written amendments thereto, summary plan
descriptions thereof and any material written employee communications with
respect to them have been furnished to Company, together with the three most
recent annual reports (Form



                                      A-18



5500 including, if applicable, Schedule B thereto) and the most recent annual
accounting, if any, of plan assets prepared in connection with any such plan.
Such plans are hereinafter referred to collectively as the "Employee Plans". For
purposes of this Section, "affiliate" of any person means any other person
which, together with Partner, is treated as a single employer under Section 414
of the Code. The only Employee Plans which, individually or collectively, would
constitute an "employee pension benefit plan" as defined in Section 3(2) of
ERISA (the "Pension Plans") are identified as such in Schedule 3.13 of the
Disclosure Schedule. Neither Partner nor any affiliate has terminated or caused
to be terminated in whole or in part or merged any Employee Plan during the
period since September 30, 1990.

                  3.13.2 No Employee Plan constitutes a "multi-employer plan,"
as defined in Section 3(37) of ERISA (a "Multi-employer Plan"); with respect to
insurance arrangements, there are no reserves, assets, surpluses or prepaid
premiums; and no Employee Plan is subject to Title IV of ERISA. Neither Partner
nor, to the knowledge of Partner, any disqualified person, as defined in Section
4975 of the Code, has engaged in any "prohibited transaction", as defined in
Section 406 of ERISA or Section 4975 of the Code, with respect to any Employee
Plan which is covered by Title I of ERISA, excluding transactions effected
pursuant to a statutory or administrative exemption.

                  3.13.3 Each Employee Plan which is intended to be qualified
under Section 401(a) of the Code is or was the subject of a favorable Internal
Revenue Service determination with respect to such qualification, and Partner
has furnished to Company copies of the most recent such determination letters,
and nothing has occurred since the date thereof that would have an adverse
effect on such qualification. There are no accrued liabilities under any
Employee Plan which have not been fully provided for by contributions to such
Employee Plans or which are not provided for on the financial statements
included in the most recently filed Partner SEC Filings. Each Employee Plan has
been maintained in substantial compliance with its terms and with the
requirements prescribed by any and all statutes, orders, rules and regulations,
including but not limited to ERISA and the Code, which are applicable to such
Employee Plans, including without limitation those requirements necessary to
maintain its qualification and the continuation of coverage requirements of Code
Section 4980B. Other than for claims in the ordinary course for benefits under
the Employee Plans, there are no suits, actions, claims or proceedings pending
or, to the knowledge of Partner, threatened which would result in any liability
with respect to any such Employee Plan.

                  3.13.4 There is no contract, agreement, plan or arrangement
covering any employee or former employee of Partner or any affiliate that,
individually or collectively, could give rise to the payment of any amount that
would not be deductible pursuant to the terms of Section 280G or Section 162(m)
of the Code.

                  3.13.5 Schedule 3.13.5 of the Disclosure Schedule sets forth a
list of each material employment, severance or other similar contract,
arrangement or policy and each plan or arrangement providing for insurance
coverage (including any self-insured



                                      A-19



arrangements), workers' compensation, disability benefits, supplemental
unemployment benefits, vacation benefits, retirement benefits or for deferred
compensation, profit-sharing, bonuses, stock options, stock appreciation or
other forms of incentive compensation or post-retirement insurance, compensation
or benefits in effect at the Effective Time which (i) is not an Employee Plan;
(ii) is entered into, maintained or contributed to, as the case may be, by
Partner or any of its subsidiaries; and (iii) covers any employee or former
employee of Partner or any of its affiliates (as defined in paragraph 3.13.1
above). Such contracts, plans and arrangements as are described above, copies or
descriptions of all of which have been furnished previously or made available to
Company are hereinafter referred to collectively as the "Benefit Arrangements."
Each Benefit Arrangement has been maintained in substantial compliance with its
terms and with the requirements prescribed by any and all statutes, orders,
rules and regulations which are applicable to such Benefit Arrangement. Partner
has no liability with respect to post-retirement medical or death benefits for
retired employees other than coverage mandated by law or death benefits under
any Pension Plan.

                  3.13.6 There has been no amendment to, written interpretation
or announcement (whether or not written) by Partner or any of its affiliates
relating to, or change in employee participation or coverage under, any Employee
Plan or Benefit Arrangement which would increase the expense (whether or not
such expense is recognized under generally accepted accounting principles) of
maintaining such Employee Plan or Benefit Arrangement above the level of the
expense incurred in respect thereof for the fiscal year ended on September 30,
1995.

                  3.13.7 With respect to any Employee Plan or Benefit
Arrangement, no event has occurred, and there exists no condition or set of
circumstances, in connection with which Partner or any such plan, directly or
indirectly, could reasonably be expected to be subject to any liability under
ERISA, the Code or any other law, regulation or governmental order, other than
ordinary contribution and benefit arrangements. With respect to each Employee
Plan and Benefit Arrangement: (i) Partner has made all payments due from it to
date or has established a reasonable reserve therefore and all amounts properly
accrued to date as liabilities of Partner which have not been paid have been
properly recorded on the books of Partner (including without limitation the
financial statements included in the most recently filed Partner SEC Filings);
(ii) no Pension Plan which is subject to ERISA section 302 or Code section 412
has incurred any "accumulated funding deficiency" (as defined in either such
section), whether or not waived; and (iii) to Partner's knowledge, there are no
unfunded benefit obligations that are not subject to United States law which are
not accounted for by reserves shown on the financial statements included in the
most recently filed Partner SEC Filings and established under generally accepted
accounting principles or otherwise noted on such financial statements.

                  3.13.8 The consummation of the transactions contemplated by
this Agreement will not (i) entitle any current or former employee of Partner or

that the enforceability thereof may be limited by applicable bankruptcy,
insolvency, reorganization or other similar laws affecting the enforcement of
creditors' rights generally and by principles of equity regarding the
availability of remedies.

         SECTION 4.6 CAPITALIZATION. The capitalization of the Company as set
forth in the financial statements most recently filed with the Company SEC
Filings is true and correct as of the date of such financial statements.

         SECTION 4.7 FINANCIAL STATEMENTS AND SEC FILINGS. Company has delivered
to Partner true and complete copies of (i) its annual reports on Form 10-K for
its fiscal years ended December 31, 1993 and 1994; (ii) its quarterly reports on
Form 10-Q for its fiscal quarters ended March 31, June 30 and September 30,
1995; (iii) its proxy or information statements relating to all meetings of, or
actions taken without a meeting by, the shareholders of Company held since
December 31, 1994; and (iv) all of its other 8-K reports filed with the SEC
since December 31, 1994. The reports and statements so delivered are referred to
collectively in this Agreement as the "Company SEC Filings." As of their
respective dates, the Company SEC Filings (including all exhibits and schedules
thereto and documents incorporated by reference therein) did not contain any
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements made, in light of the circumstances under which
they were made, not misleading. The audited financial statements and unaudited
interim financial statements of Company included or incorporated by reference



                                      A-30



in the Company SEC Filings (i) have been prepared in accordance with generally
accepted accounting principles applied on a consistent basis during the periods
involved (except as may be indicated in the notes thereto); (ii) complied as of
their respective dates in all material respects with applicable accounting
requirements and the published rules and regulations of the SEC with respect
thereto; and (iii) fairly present the financial position of Company as of the
dates thereof and the income and cash flows for the periods then ended (subject,
in the case of any unaudited interim financial statements, to normal year-end
adjustments).

         SECTION 4.8 MATERIAL EVENTS. Except as disclosed in the Company SEC
Filings, and except as expressly contemplated by this Agreement, since the date
of the most recent audited financial statements included in the Company SEC
Filings there has not been any event, occurrence or development of a state of
circumstances or facts which has had a Material Adverse Effect.

         SECTION 4.9 OPINION OF FINANCIAL ADVISOR. The Company has received the
opinion of Piper Jaffray Inc., dated the date hereof, to the effect that, as of
such date, the consideration to be paid by the Company in the Merger is fair to
the shareholders of the Company from a financial point of view and such opinion
shall not have been withdrawn by the Closing.

         SECTION 4.10 TAX MATTERS. Neither the Company nor, to its knowledge,
any of its affiliates, has taken or agreed to take any action, or knows of any
circumstances, that (without regard to any action taken or agreed to be taken by
Partner or any of its affiliates) would prevent the Merger from qualifying as a
reorganization within the meaning of Section 368(a) of the Code.

         SECTION 4.11 FULL DISCLOSURE. The representations and warranties of
Company contained in this Agreement contain no untrue statements of any material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, taken as a whole, not false or misleading.

protection from creditors.

                  5.1.11 Except for those transactions which constitute an
Acquisition Proposal, Partner will not take any action, the taking of which, or
omit to take any action, the omission of which, would reasonably be expected to
cause any of the representations and warranties in Article III to be inaccurate
in any respect at or as of any time prior to the Effective Time.

                  5.1.12 Except for the sale of inventory and the disposition of
obsolete or defective equipment, Partner will not without the prior written
consent of Company sell, transfer, mortgage, or otherwise dispose of, or

                                      A-33



to have cleared by the SEC, and promptly thereafter shall mail to shareholders
of Partner, a proxy statement (the "Proxy Statement"). The Proxy Statement shall
be in form and substance reasonably satisfactory to Partner and Company and

authorized representatives such financial and operating data and other
information as such persons may reasonably request, other than the information
that, in the opinion of Partner's legal counsel, may not be disclosed under
applicable law. Partner will advise Company of the general nature of any such
withheld document or information and the reasons for withholding same. Partner
will instruct Partner's employees, counsel and financial advisors to cooperate
fully with the other party in its investigation of the business of Partner;

obtained hereunder will be subject to the confidentiality agreement described in
Section 11.5 below.

         SECTION 5.4 NOTICES OF CERTAIN EVENTS. Partner shall promptly notify
Company of:

                  (i) any notice or other communication from any person alleging
         that the consent of such person is or may be required in connection
         with the transactions contemplated by this Agreement;

                  (ii) any notice or other communication from any governmental
         or regulatory agency or authority in connection with the transactions
         contemplated by this Agreement;



                                      A-34



                  (iii) any actions, suits, claims, investigations or
         proceedings commenced or, to Partner's knowledge, overtly threatened
         against, relating to or involving or otherwise affecting Partner which
         relate to the consummation of the transactions contemplated by this
         Agreement; and

                  (iv) any other event or change of fact or circumstance
         subsequent to the date of this Agreement causing any representation
         contained in Article III of this Agreement to be, as of the date of
         such event or change, materially incorrect or misleading.

         SECTION 5.5 CONSENTS, APPROVALS AND FILINGS. Partner will use its
reasonable efforts to obtain as promptly as possible (i) all necessary
approvals, authorizations, consents, licenses, clearances or orders of
governmental and regulatory authorities required in order for Partner to perform

required in connection with the contracts identified in Schedule 3.18 of the

         SECTION 5.6 REASONABLE EFFORTS. Subject to the fiduciary duties of its

satisfied by it; (ii) to cause to be performed all of the matters required of it
at or prior to the Effective Time; and (iii) to comply with applicable law.

         SECTION 5.7 EXCLUSIVITY. In order to induce Company to enter into this
Agreement and subject to the fiduciary duties of the Board of Directors of
Partner, until this Agreement is terminated in accordance with its terms,
Partner shall not, and shall direct and use its reasonable efforts to cause its
respective officers, directors, employees, agents and representatives
(including, without limitation, any investment banker, attorney or accountant
retained by it) not to, directly or indirectly, (a) take any further action to
solicit, initiate or encourage any offer or indication of interest from any
person with respect to any Acquisition Proposal (as hereinafter defined),
including without limitation, any such further action through any investment
banker, broker, finder or other intermediary previously engaged or which may be
engaged for the purpose of soliciting, initiating or encouraging such offer or
indication of interest; or (b) engage in negotiations with, or disclose any
non-public information relating to the businesses, assets or operations which
are the subject of this Agreement or afford access to the properties, books or
records of Partner to, any person that has made, or that Partner has good reason
to believe may be considering making, an Acquisition Proposal. Subject to the
fiduciary duties of the Board of Directors of Partner, Partner will promptly
notify Company after receipt of any Acquisition Proposal or indication, in
writing, that any person is considering making an Acquisition Proposal and will
keep Company reasonably informed of any such offer or indication. Subject to the
fiduciary duties of the Board of Directors of Partner, Partner will not enter
into any agreement relating to any such Acquisition Proposal for a period of
seven (7) days following receipt by Company of such notification by Partner.
"Acquisition Proposal" means any proposal to (i) effect a merger or
consolidation or similar transaction involving Partner or any of its
subsidiaries; (ii) purchase, lease, or otherwise



                                      A-35



acquire ten percent (10%) or more of the assets of Partner or any of its
subsidiaries; (iii) purchase or otherwise acquire (including by way of merger,
consolidation, share exchange or similar transaction) beneficial ownership (as
defined in Rule 13d-3 under the Securities Exchange Act of 1934) of securities
representing ten percent (10%) or more of the voting power of Partner or any of
its subsidiaries; or (iv) the assignment, transfer, licensing or other
disposition of, in whole or in part, the patents, patent rights, trade secrets
or other technology of Partner or any of its subsidiaries, other than in the
ordinary course of business. Where Partner takes action or fails to take action
required by this Section 5.7 due to a belief that to do otherwise would result
in a breach of the fiduciary duties of the Board of Directors, Partner may do so
only after receipt of a written opinion of its legal counsel or upon advice of
its legal counsel confirmed by a written opinion of such counsel, and a copy of
such opinion shall be furnished to the Company.

         SECTION 5.8 RETURN OF CONFIDENTIAL INFORMATION. Promptly following the
execution of this Agreement, Partner shall exercise its right under all
confidentiality or other non-disclosure agreements entered into with parties
approached by Partner or its agents since September 30, 1995 to retrieve any and
all information provided by or on behalf of Partner to such parties.

         from accounting for the Merger as a pooling of interests; or

                  (b) intentionally take any action that (without regard to any

purpose of registering the shares of Company Common Stock to be issued in the
Merger under the 1933 Act. Such Registration Statement shall contain a
prospectus and the Proxy Statement (the "Prospectus and Proxy Statement") which
shall include information regarding Company, Partner, the combined entity and
the terms of the Merger, among other things. Neither the Registration Statement
nor any amendments thereto shall be filed with the SEC unless approved by

withheld. Each of Company and Partner shall furnish all information concerning
itself to the other as may be reasonably



                                      A-39



requested in connection with any such action and the preparation, filing and
distribution of the Registration Statement and the Prospectus and Proxy

based on information supplied by Company specifically for inclusion or
incorporation by reference in the Proxy Statement. None of the information
supplied or to be supplied by Partner specifically for inclusion or
incorporation by reference in (i) the Registration Statement will, at the time
the Registration Statement is filed with the SEC, at any time it is amended or
supplemented, and at the time it becomes effective under the 1933 Act; or (ii)
the Proxy Statement, at the date it is first mailed to Partner's shareholders
and at the time of the meeting of Partner's shareholders held to vote on
approval of this Agreement and the Merger, contains any untrue statement of any
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading. Partner will
promptly advise Company in writing if at any time prior to the Effective Time of
the Merger it shall obtain knowledge of any facts that might make it necessary
or appropriate to amend or supplement the Proxy Statement or the Registration
Statement in order to make the statements contained or incorporated by reference
therein not misleading or to comply with applicable law.

                                                                       EXHIBIT B

                             SHAREHOLDERS AGREEMENT

         AGREEMENT dated as of January 29, 1996 by and between St. Jude Medical,
Inc., a Minnesota corporation ("Company"), Daig Corporation, a Minnesota
corporation ("Partner") and the other parties signatory hereto (each a
"Shareholder").

         Concurrently herewith, Company, Partner Acquisition Corp., a Minnesota
corporation and a wholly owned subsidiary of Company (the "Merger Subsidiary"),
and Partner are entering into an Agreement and Plan of Merger (as such agreement
may be amended from time to time, the "Merger Agreement"; capitalized terms used
but not defined herein shall have the meanings set forth in the Merger
Agreement) pursuant to which Merger Subsidiary will be merged with and into
Partner (the "Merger"), whereby the shares of common stock, par value $.01 per
share, of Partner ("Partner Common Stock") issued and outstanding and held by
each shareholder of Partner immediately prior to the Effective Time of the
Merger (other than (i) shares of Partner Common Stock owned, directly or
indirectly, by Partner or any subsidiary of Partner or the Merger Subsidiary or
any other subsidiary of the Company, and (ii) Dissenting Shares) will be
converted into the right to receive common stock, par value $.10 per share, of
the Company ("Company Common Stock") (and cash in lieu of any fractional share).

         As a condition of their willingness to enter into the Merger Agreement,
the Company and Merger Subsidiary have agreed that each Shareholder enter into,
and each such Shareholder has agreed to enter into, this Agreement.

                                    AGREEMENT

         To implement the foregoing and in consideration of the mutual
agreements contained herein, the parties agree as follows:

          1.      Representations and Warranties.

                  1.1 Except as set forth in Schedule 1, each Shareholder hereby
severally represents and warrants to the Company as follows:

                  (a) Ownership of Shares. Such Shareholder is either (i) the
record and beneficial owner of, (ii) trustee of a trust that is the record
holder or beneficial owner of, and whose beneficiaries are the beneficial owners
(such trustee, a "Trustee") of, or (iii) the beneficial owner but not the record
holder of, the number of shares of Partner Common Stock as set forth opposite
such Shareholder's name on Schedule 1 hereto (the "Shares"). Such Shareholder
has sole voting power and sole power to issue instructions with respect to the
matters set forth in Section 2 hereof, sole power of disposition, sole power of
conversion, and sole power to demand appraisal rights, in each case with respect
to all of the Shares set forth opposite such Shareholder's



                                       B-1



name on Schedule 1, with no restrictions, subject to applicable federal
securities laws and the terms of this Agreement, on such rights.

         (b) Power; Binding Agreement. Such Shareholder has the legal capacity,
power and authority to enter into and perform all of such Shareholder's
obligations under this Agreement. The execution, delivery and performance of
this Agreement by such Shareholder will not violate any other agreement to which
such Shareholder is a party including, without limitation, any trust agreement,
voting agreement, shareholders agreement or voting trust. This Agreement has
been duly and validly executed and delivered by such Shareholder and constitutes
a valid and binding agreement of such Shareholder in accordance with its terms.
There is no beneficiary or holder of a voting trust certificate or other
interest of any trust of which a Shareholder is Trustee whose consent is
required for the execution and delivery of this Agreement or the consummation of
the transactions contemplated hereby. If such Shareholder is married and such
Shareholder's Shares constitute community property, this Agreement has been duly
authorized, executed and delivered by, and constitutes a valid and binding
agreement of, such Shareholder's spouse, enforceable against such person in
accordance with its terms.

         (c) No Conflicts. Except for filings under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, if applicable, (i) no filing
with, and no permit, authorization, consent or approval of, any state or federal
public body or authority is necessary for the execution of this Agreement by
such Shareholder and the consummation by such Shareholder of the transactions
contemplated hereby and (ii) neither the execution and delivery of this
Agreement by such Shareholder nor the consummation by such Shareholder of the
transactions contemplated hereby nor compliance by such Shareholder with any of
the provisions hereof will (A) conflict with or result in any breach of any
applicable trust or other organizational documents applicable to such
Shareholder, (B) result in a violation or breach of, or constitute (with or
without notice or lapse of time or both) a default (or give rise to any third
party right of termination, cancellation, material modification or acceleration)
under any of the terms, conditions or provisions of any note, bond, mortgage,
indenture, license, contract, commitment, arrangement, understanding, agreement
or other instrument or obligation of any kind to which such Shareholder is a
party or by which such Shareholder or any of such Shareholder's properties or
assets may be bound or (C) violate any order, writ, injunction, decree,
judgment, order, statute, rule or regulation applicable to such Shareholder or
any of such Shareholder's properties or assets.

         (d) No Encumbrances. Such Shareholder's Shares and the certificates
representing such Shares are now and at all times during the term hereof will be
held by such Shareholder, or by a nominee or custodian for the benefit of such
Shareholder free and clear of all liens, claims, security interests, proxies,
voting trusts or agreements, understandings, or arrangements or any other
encumbrances whatsoever except for any such encumbrances or proxies arising
hereunder.

         (e) No Broker. Except as set forth in the Merger Agreement no broker,
investment banker, financial adviser or other person is entitled to any
broker's, finder's, financial adviser's or



                                       B-2



other similar fee or commission in connection with the transactions contemplated
hereby based upon arrangements made by or on behalf of such Shareholder.

         (f) Acknowledgment of Reliance. Such Shareholder understands and
acknowledges that the Company is entering into, and causing Merger Subsidiary to
enter into, the Merger Agreement in reliance upon such Shareholder's execution
and delivery of this Agreement.

                  1.2 Partner represents and warrants to the Shareholders and
the Company that the Shares subject to this Agreement and the Proxy are less
than 20% of the issued and outstanding Partner Common Stock.

         2.       Agreement to Vote, Proxy.

                  2.1 Voting. Each Shareholder, in his capacity as a shareholder
of Partner, hereby severally agrees that, during the time this Agreement is in
effect, at any meeting of the shareholders of Partner, however called, or in
connection with any written consent of shareholders of Partner, such Shareholder
shall vote (or cause to be voted) the Shares (a) in favor of the Merger, the
execution and delivery by Partner of the Merger Agreement and the approval of
the terms thereof and each of the other actions contemplated by the Merger
Agreement and this Agreement and any actions required in furtherance hereof and
thereof; (b) against any action or agreement that would result in a breach in
any material respect of any covenant, representation or any other obligation or
agreement of Partner under the Merger Agreement or this Agreement; (c) except as
otherwise agreed to in writing in advance by the Company, against the following
actions (other than the Merger and the transactions contemplated by the Merger
Agreement): (i) any extraordinary corporate transaction, such as a merger,
consolidation or other business combination involving Partner or its
subsidiaries; (ii) a sale, lease or transfer of a material amount of assets of
Partner or its subsidiaries or a reorganization, recapitalization, dissolution
or liquidation of Partner or its subsidiaries; (iii) (1) any material change in
the present capitalization of Partner or any amendment of Partner's Articles of
Incorporation; (2) any other material change in Partner's corporate structure or
business; or (3) any other action; which, in the case of each of the matters
referred to in clauses iii(1), (2) or (3), is intended, or could reasonably be
expected, to impede, interfere with, delay, postpone, discourage or materially
adversely affect the contemplated economic benefits to the Company of the Merger
or the transactions contemplated by the Merger Agreement. Such Shareholder shall
not enter into any agreement or understanding with any person or entity prior to
the Termination Date (as defined in Section 8) to vote or give instructions with
respect to the Shares after the Termination Date in any manner inconsistent with
clauses (i), (ii) or (iii) of the preceding sentence.

         2.2 Proxy. Concurrently with the Shareholder's execution of this
Agreement, the Shareholder has executed and delivered to the Company an
irrevocable proxy (the "Proxy") in the form of Exhibit 1 attached hereto,
appointing the officers of the Company named therein, or either of them, as
proxy for the Shareholder to vote the Shares in accordance with Section 2.1
above.



                                       B-3



         3. Certain Covenants of Shareholders. Except in accordance with the
terms of this Agreement, each Shareholder hereby severally covenants and agrees
as follows:

                  3.1 No Solicitation. No Shareholder, in his capacity as
shareholder, shall, directly or indirectly, solicit (including, by way of
furnishing information) or respond to any inquiries making of any proposal by
any person or entity (other than the Company or any affiliate of the Company)
with respect to Partner that constitutes or could reasonably be expected to lead
to an Acquisition Proposal or a proposal for an Acquisition Proposal. If any
Shareholder, in his capacity as shareholder, receives any such inquiry or
proposal, then such Shareholder shall promptly inform the Company of the terms
and conditions, if any, of such inquiry or proposal and the identity of the
person making it. Each Shareholder, in his capacity as shareholder, will
immediately cease and cause to be terminated any existing activities,
discussions or negotiations with any parties conducted heretofore with respect
to any of the foregoing. Nothing in this Section 3.1 shall prohibit or restrict,
in any manner whatsoever, a Shareholder from exercising, in his capacity as an
officer or director of Partner, his fiduciary duties in such capacity with
respect to any of the matters covered by this Section 3.1.

                  3.2 Restriction on Transfer, Proxies and Non-Interference on
Withdrawal. No Shareholder, in his capacity as shareholder, shall, directly or
indirectly: (a) except pursuant to the terms of the Merger Agreement, offer for
sale, sell, transfer, tender, pledge, encumber, assign or otherwise dispose of,
or enter into any contract, option or other arrangement or understanding with
respect to or consent to the offer for sale, sale, transfer, tender, pledge,
encumbrance, assignment or other disposition of, any or all of such
Shareholder's Shares or any interest therein; (b) except as contemplated hereby,
grant any proxies or powers of attorney, deposit any Shares into a voting trust
or enter into a voting agreement with respect to any Shares; (c) take any action
that would make any representation or warranty of such Shareholder contained
herein untrue or incorrect or have the effect of preventing or disabling such
Shareholder from performing, such Shareholder's obligations under this Agreement
or (d) following the merger, sell any shares of Company Common Stock until such
time as unaudited financial statements covering at least thirty days of the
combined operations of the Company and Partner following the Merger have been
published by the Company.

                  3.3 Waiver of Appraisal Rights. Each Shareholder hereby agrees
that, in the event that any election is available to such Shareholder with
respect to consideration available in the Merger or any information or
cooperation must be provided in order to obtain any form of consideration in the
Merger, such Shareholder will make all elections and provide all information and
cooperation necessary to obtain the maximum number of shares of Company Common
Stock available in the Merger. Each Shareholder hereby waives any rights of
appraisal or rights to dissent from the Merger that such Shareholder may have
and agrees to take no action in furtherance of the perfection of such rights.

         4. Registration Rights.



                                       B-4



                  4.1 Company Registration. If, as a result of the Shareholder's
execution of this Agreement and the Proxy, any shares of Company Common Stock
received by the Shareholder pursuant to the Merger (the "Merger Shares") are not
deemed to have been registered under the Securities Act of 1933, as amended,
notwithstanding the filing of a registration statement on Form S-4, filed in
connection with the Merger, then as soon as practicable following the Effective
Time, Company shall file a shelf registration statement pursuant to form S-3
under the 1933 Act providing for sale by the Shareholder, from time to time of
the Merger Shares and, if required, under applicable state securities laws, to
register the resale of Shareholder's Merger Shares and use all reasonable
efforts to cause such registration statement to become effective and be
maintained until the Merger Shares are eligible for resale under Rule 144 of the
1933 Act. Company will furnish Shareholder with a reasonable number of copies of
any prospectus included in any such registration statement, and Company and each
Shareholder will enter into cross-indemnification agreements with each other in
customary scope covering the accuracy and completeness of the information
furnished by each for use in or incorporation into such registration statement.
All expenses incurred by Company in effecting or maintaining any registration of
the Merger Shares in accordance with this Section 4 shall be borne by Company;
provided, however, that Shareholder shall be responsible for the fees and
expenses of his legal counsel and any underwriting or brokerage commissions or
discounts applicable to his resale or disposition of his Merger Shares.

                  4.2 Draw Down Notice; Blockage. Shareholder agrees to provide
the Company with at least five business days notice of its intent to draw down
all or any portion of the Merger Shares under the registration statement (a
"Draw Down Notice"). If the Company notifies Shareholder in writing within three
business days of its receipt of a Draw Down Notice that, in the Company's good
faith judgment, a sale of Merger Shares under the registration statement would
be detrimental to the Company, Shareholder agrees not to sell Merger Shares
under the registration statement. If the Company notifies Shareholder that such
a sale is permissible, or fails to notify Shareholder that such a sale cannot be
made within three business days, Shareholder shall have a period of thirty days
from the expiration of such five business days to sell the Merger Shares
pursuant to the registration statement. In the event such a sale was not
permitted by the Company, the Company shall promptly notify Shareholder when
Shareholder may sell securities pursuant to the registration statement. In no
event shall Shareholder be precluded from selling Merger Shares for more than
120 days in any calendar year. Shareholder will not sell Merger Shares pursuant
to the registration statement except as permitted by this Section 4.2.

         5. Further Assurances. From time to time, at the other party's request
and without further consideration, each party hereto shall execute and deliver
such additional documents and take all such further action as may be necessary
or desirable to consummate and make effective, in the most expeditions manner
practicable, the transactions contemplated by this Agreement.

         6. Certain Events. Each Shareholder agrees that this Agreement and the
obligations hereunder shall attach to such Shareholder's Shares and shall be
binding upon any person or entity



                                       B-5



to which legal or beneficial ownership of such Shares shall pass, whether by
operation of law or otherwise, including without limitation such Shareholder's
heirs, guardians, administrators or successors.

         7. Stop Transfer. Each Shareholder agrees with, and covenants to, the
Company that such Shareholder shall not request that Partner or its transfer
agent register the transfer (book-entry or otherwise) of any certificate or
uncertificated interest representing any of such Shareholder's Shares, unless
such transfer is made in compliance with this Agreement. Each Shareholder
agrees, with respect to any Shares in certificated form, that such Shareholder
will tender to Partner, within 15 business days after the date hereof, the
certificates representing such Shares and Partner (or Partner's transfer agent)
will inscribe upon such certificates the following legend: "The shares of Common
Stock, par value $.01 per share, of Daig Corporation ("Partner") represented by
this certificate are subject to a Shareholders Agreement dated as of January 29,
1996, and may not be sold or otherwise transferred, except in accordance
therewith. Copies of such Agreement may be obtained at the principal executive
offices of Partner." Each Shareholder agrees that within 15 business days after
the date hereof, such Shareholder will no longer hold any Shares, whether
certificated or uncertificated, in "street name", or in the name of any nominee.
Following the Merger, the Company will not register the transfer (book-entry or
otherwise) of any certificate or uncertificated interest representing any of
Shareholder's Company Common Stock, unless such transfer is made in compliance
with this Agreement. Certificates representing Company Common Stock which are
distributed to Shareholders as Merger Consideration or are otherwise subject to
the terms of this Agreement shall bear the following legend: "The Shares of
Common Stock, par value $.10 per share of St. Jude Medical, Inc. (the "Company")
represented by this certificate are subject to a Shareholders Agreement dated as
of January 29, 1996 and may not be sold or otherwise transferred except in
accordance therewith. Copies of such Agreement may be obtained at the principal
executive offices of the Company." Certificates with such legend may be
exchanged for certificates without such legend in connection with a proposed
transfer if it is established to the reasonable satisfaction of the Company that
such transfer is not prohibited hereunder. In addition, any certificates bearing
such legend may be exchanged for certificates without such legend upon
termination of the Merger Agreement. In the event of a stock dividend or
distribution, or any change in Partner Common Stock by reason of any stock
dividend, split-up, recapitalization, combination, exchange of shares or the
like, the term "Shares" shall be deemed to refer to and include the Shares as
well as all such stock dividends and distributions and any shares into which or
for which any or all of the Shares may be changed or exchanged.

         8. Termination. The covenants and agreements contained herein with
respect to Partner Common Stock shall terminate on the first to occur of (a) the
Effective Time of the Merger and (b) the date upon which the Merger Agreement is
terminated in accordance with its terms. The covenants and agreements contained
herein with respect to Company Common Stock shall terminate (i) following the
event described in Section 3.2(iv) above, or (ii) upon removal of the legend
thereon in accordance with Section 6 above.

         9. Shareholder Capacity. No person executing this Agreement who is or
becomes



                                       B-6



during the term hereof a director of the Company makes any agreement or
understanding herein in his or her capacity as such director. Each Shareholder
signs solely in his or her capacity as the record and beneficial owner of, or
the trustee of a trust whose beneficiaries are the beneficial owners of, such
Shareholder's Shares.

         10. Miscellaneous.

                  10.1 Entire Agreement: Assignment. This Agreement (i)
constitutes the entire agreement between the parties with respect to the subject
matter hereof and supersedes all other prior agreements and understandings, both
written and oral, between the parties with respect to the subject manner hereof
and (ii) shall not be assigned by operation of law or otherwise without the
prior written consent of the other party provided that the Company may assign,
in its sole discretion, its rights and obligations hereunder to any direct or
indirect wholly-owned subsidiary of the Company, but no such assignment shall
relieve the Company of its obligations hereunder if such assignee does not
perform such obligations.

                  10.2 Amendments. This Agreement may not be modified, amended,
altered or supplemented, except upon the execution and delivery of a written
agreement executed by the parties hereto; provided that Schedule 1 hereto may be
supplemented by the Company by adding the name and other relevant information
concerning any Shareholder of Partner who agrees to be bound by the terms of
this Agreement without the agreement of any other party hereto, and thereafter
such added Shareholder shall be treated as a "Shareholder" for all purposes of
this Agreement.

                  10.3 Notices. All notices, requests, claims, demands and other
communications hereunder shall be in writing and shall be given (and shall be
deemed to have been duly received if so given) by hand delivery, telegram, telex
or telecopy, or by mail (registered or certified mail, postage prepaid, return
receipt requested) or by any courier service, such as Federal Express, providing
proof of delivery. All communications hereunder shall be delivered to the
respective parties at the following addresses:

                  10.4 Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Minnesota regardless of
the laws that might otherwise govern under applicable principles of conflict of
laws thereof.

                  10.5 Specific Performance. Each of the parties hereto
recognizes and acknowledges that a breach by it of any covenants or agreements
contained in this Agreement will cause the other party to sustain damages for
which it would not have an adequate remedy at law for money damages, and
therefore each of the parties hereto agrees that in the event of any such breach
the aggrieved party shall be entitled to the remedy of specific performance of
such covenants and agreements and injunctive and other equitable relief in
addition to any other remedy to which it may be entitled, at law or in equity.
The Company agrees that it shall not bring any action for money damages relating
to this Agreement or the transactions herein contemplated against any trustee of
any Shareholder that is a trust in such trustee's personal capacity based upon
any action taken or not taken pursuant to a court order or a final legal
judgment.

                  10.6 Counterparts. This Agreement may be executed in two
counterparts, each of which shall be deemed to be an original, but both of which
shall constitute one and the same Agreement.

                  10.7 Descriptive Headings. The descriptive headings used
herein are inserted for convenience of reference only and are not intended to be
part of or to affect the meaning, or interpretation of this Agreement.

                  10.8 Severability. Whenever possible, each provision or
portion of any provision of this Agreement will be interpreted in such manner as
to be effective and valid under applicable law but if any provision or portion
of any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or portion of any provision in such jurisdiction, and this
Agreement will be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision or portion of any provision had
never been contained herein.

                  10.9 Definitions. For purposes of this Agreement:

                           (a) "Beneficially Own" or "Beneficial Ownership" with
respect to any securities shall mean having "Beneficial Ownership" of such
securities (as determined pursuant to Rule 13d-3 under the Exchange Act),
including, pursuant to any agreement, arrangement or understanding, whether or
not in writing. Without duplicative counting, of the same securities by the same
holder, securities Beneficially Owned by a Person shall include securities
Beneficially



                                       B-8

Board of Directors
Daig Corporation
14901 Deveau Place
Minnetonka, Minnesota 55345


Gentlemen:

You have requested our opinion as to the fairness to the holders of the
outstanding shares of Common Stock, par value $0.01 per share (the "Shares"), of
Daig Corporation (the "Company") of the conversion ratio of 0.651733 shares of
Common Stock of St. Jude Medical, Inc. ("St. Jude"), par value $0.10 per share
(the "St. Jude Shares") to be received by such holders for each Share (the
"Conversion Ratio") pursuant to the Agreement and Plan of Merger dated as of
January 29, 1996 among St. Jude, Partner Acquisition Corp., a wholly owned
subsidiary of St. Jude ("St. Jude Sub"), and the Company (the "Agreement"). In
the event that the Reference Market Value (as defined in the Agreement) of a St.
Jude Share is less than $34.00, the Company has the option to terminate the
Agreement.

Goldman, Sachs & Co., as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes. We are familiar with
the Company, having acted as its financial advisor in connection with, and
having participated in certain of the negotiations leading to, the Agreement. As
disclosed to the Company previously, Goldman, Sachs & Co. has provided certain
investment banking services to St. Jude from time to time. In the course of the
trading activities of Goldman, Sachs & Co. we may from time to time hold
positions in securities or options on securities of St. Jude and of the Company.
As of the close of business on January 25, 1996, Goldman, Sachs & Co. had
accumulated a long position of 91.786 St. Jude Shares.

In connection with this opinion, we have reviewed, among other things, the
Agreement; Annual Reports on Form 10-K of the Company for the five fiscal years
ended September 30, 1995; Annual Reports to Stockholders and Annual Reports on
Form 10-K of St. Jude for the five years ended December 31, 1994; certain
interim reports to stockholders and Quarterly Reports on Form 10-Q of the
Company and St. Jude; certain other communications from the Company and St. Jude
to their respective stockholders; and certain internal financial analyses and
forecasts for the Company and St. Jude prepared by their respective managements.
We also have held discussions with members of the senior management of the
Company and St. Jude regarding the past and current business operations,
financial condition and future prospects of their respective companies and we
have reviewed financial forecasts prepared for each business by their respective
managements. In addition, we have reviewed the reported price and trading
activity for the Shares and St. Jude Shares, compared certain financial and
stock market information for the Company and St. Jude with similar information
for certain other companies the securities of which are publicly traded,
reviewed the financial terms of certain recent business combinations in the
medical device and hospital supply industries specifically and in other
industries generally and performed such other studies and analyses as we
considered appropriate.

We have relied without independent verification upon the accuracy and
completeness of all of the financial and other information reviewed by us for
purposes of this opinion. In that regard, we have assumed, with your consent,
that the financial forecasts, including, without limitation, projected cost
savings and operating synergies resulting from the merger have been reasonably
prepared on a basis reflecting the best currently available judgments and
estimates of the Company and St. Jude and that such forecasts will be realized
in the amounts and at the times contemplated thereby. In addition, we have not
made an independent evaluation or appraisal of the assets and liabilities of the
Company or St. Jude or any of their respective subsidiaries, and we have not
been furnished with any such evaluation or appraisal. We have assumed with your
consent that the Merger will be accounted for as a pooling of interests under
generally accepted accounting principles.

Based upon and subject to the foregoing and based upon such other matters as we
consider relevant, it is our opinion that as of the date hereof the Conversion
Ratio pursuant to the Agreement is fair to the holders of the Shares.

Very truly yours,

/s/ GOLDMAN, SACHS & CO.

GOLDMAN, SACHS & CO.

              PROVISIONS OF THE MINNESOTA BUSINESS CORPORATION ACT
                  RELATING TO RIGHTS OF DISSENTING STOCKHOLDERS


302A.471.  RIGHTS OF DISSENTING SHAREHOLDERS

         Subdivision 1. Actions creating rights. A shareholder of a corporation
may dissent from, and obtain payment for the fair value of the shareholder's
shares in the event of, any of the following corporate actions:

         (a) An amendment of the articles that materially and adversely affects
the rights of preferences of the shares of the dissenting shareholder in that
it:

                  1. alters or abolishes a preferential right of the shares;

                  2. creates, alters, or abolishes a right in respect of the
         redemption of the shares, including a provision respecting a sinking
         fund for the redemption or repurchase of the shares.

                  3. alters or abolishes a preemptive right of the holder of the
         shares to acquire shares, securities other than shares, or rights to
         purchase shares or securities other than shares;

                  4. excludes or limits the right of a shareholder to vote on a
         matter, or to cumulate votes, except as the right may be excluded or
         limited through the authorization or issuance of securities of an
         existing or new class or series with similar or different voting
         rights; except that an amendment ot the articles of an issuing public
         corporation that provides that section 302A.671 does not apply to a
         control share acquisition does not give rise to the right to obtain
         payment under this section;

         (b) A sale, lease, transfer, or other disposition of all or
substantially all of the property and assets of the corporation, but not
including a transaction permitted without shareholder approval in section
302A.661, subdivision 1, or a disposition in dissolution described in section
302A.725, subdivision 2, or a disposition pursuant to an order of a court, or a
disposition for cash on terms requiring that all or substantially all of the net
proceeds of disposition be distributed to the shareholders in accordance with
their respective interests within one year after the date of disposition;

         (c) A plan of merger, whether under this chapter or under chapter 322B,
to which the corporation is a party, except as provided in subdivision 3;

         (d) A plan of exchange, whether under this chapter or under chapter
322B, to which the corporation is a party as the corporation whose shares will
be acquired by the acquiring corporation, if the shares of the shareholder are
entitled to be voted on the plan; or

         (e) Any other corporate action taken pursuant to a shareholder vote
with respect to which the articles, the bylaws, or a resolution approved by the
board directs that dissenting shareholders may obtain payment for their shares.

         Subd. 2. Beneficial owners. (a) A shareholder shall not assert
dissenters' rights as to less than all of the shares registered in the name of
the shareholder, unless the shareholder dissents with respect to all the shares
that are beneficially owned by another person but registered in the name of the
shareholder and discloses the name and address of each beneficial owner on whose
behalf the shareholder dissents. In that event, the rights of the dissenter
shall be determined as if the shares as to which the shareholder has dissented
and the other shares were registered in the names of different shareholders.

         (b) The beneficial owner of shares who is not the shareholder may
assert dissenters' rights with respect to shares held on behalf of the
beneficial owner, and shall be treated as a dissenting shareholder under the
terms of this



                                       D-1



section and section 302A.473, if the beneficial owner submits to the corporation
at the time of or before the assertion of the rights a written consent of the
shareholder.

         Subd. 3. Rights not to apply. Unless the articles, the bylaws, or a
resolution approved by the board otherwise provide, the right to obtain payment
under this section does not apply to a shareholder of the surviving corporation
in a merger, if the shares of the shareholder are not entitled to be voted on
the merger.

         Subd. 4. Other rights. The shareholders of a corporation who have a
right under this section to obtain payment for their shares do not have a right
at law or in equity to have a corporate action described in subdivision 1 set
aside or rescinded, except when the corporate action is fraudulent with regard
to the complaining shareholder or the corporation.

302A.473  PROCEDURES FOR ASSERTING DISSENTERS' RIGHTS

         Subdivision 1. Definitions. (a) For purposes of this section, the terms
defined in this subdivision have the meanings given them.

         (b) "Corporation" means the issuer of the shares held by a dissenter
before the corporate action referred to in section 302A.471, subdivision 1 or
the successor by merger of that issuer.

         (c) "Fair value of shares" means the value of the shares of a
corporation immediately before the effective date of the corporate action
referred to in section 302A.471, subdivision 1.

         (d) "Interest" means interest commencing five days after the effective
date of the corporate action referred to in section 302A.471, subdivision 1, up
to and including the date of payment, calculated at the rate provided in section
549.09 for interest on verdicts and judgments.

         Subd. 2. Notice of action. If a corporation calls a shareholder meeting
at which any action described in section 302A.471, subdivision 1 is to be voted
upon, the notice of the meeting shall inform each shareholder of the right to
dissent and shall include a copy of section 302A.471 and this section and a
brief description of the procedure to be followed under these sections.

         Subd. 3. Notice of dissent. If the proposed action must be approved by
the shareholders, a shareholder who wishes to exercise dissenters' rights must
file with the corporation before the vote on the proposed action a written
notice of intent to demand the fair value of the shares owned by the shareholder
and must not vote the shares in favor of the proposed action.

         Subd. 4. Notice of procedure; deposit of shares. (a) After the proposed
action has been approved by the board and, if necessary, the shareholders, the
corporation shall send to all shareholders who have complied with subdivision 3
and to all shareholders entitled to dissent if no shareholder vote was required,
a notice that contains:

                  (1) The address to which a demand for payment and certificates
         of certificated shares must be sent in order to obtain payment and the
         date by which they must be received;

                  (2) Any restrictions on transfer of uncertified shares that
         will apply after the demand for payment is received;

                  (3) A form to be used to certify the date on which the
         shareholder, or the beneficial owner on whose behalf the shareholder
         dissents, acquired the shares or an interest in them and to demand
         payment; and



                                       D-2



                  (4) A copy of section 302A.471 and this section and a brief
         description of the procedures to be followed under these sections.

         (b) In order to receive the fair value of the shares, a dissenting
shareholder must demand payment and deposit certificated shares or comply with
any restrictions on transfer of uncertificated shares within 30 days after the
notice required by paragraph (a) was given, but the dissenter retains all other
rights of a shareholder until the proposed action takes effect.

         Subd. 5. Payment, return of shares. (a) After the corporate action
takes effect, or after the corporation receives a valid demand for payment,
whichever is later, the corporation shall remit to each dissenting shareholder
who has complied with subdivisions 3 and 4 the amount the corporation estimates
to be the fair value of the shares, plus interest, accompanied by:

                  (1) The corporation's closing balance sheet and statement of
         income for a fiscal year ending not more than 16 months before the
         effective date of the corporate action, together with the latest
         available interim financial statements;

                  (2) An estimate by the corporation of the fair value of the
         shares and a brief description of the method used to reach the
         estimate; and

                  (3) A copy of section 302A.471 and this section, and a brief
         description of the procedure to be followed in demanding supplemental
         payment.

         (b) The corporation may withhold the remittance described in paragraph
(a) from a person who was not a shareholder on the date the action dissented
from was first announced to the public or who is dissenting on behalf of a
person who was not a beneficial owner on that date. If the dissenter has
complied with subdivisions 3 and 4, the corporation shall forward to the
dissenter the materials described in paragraph (a), a statement of the reason
for withholding the remittance, and an offer to pay to the dissenter the amount
listed in the materials if the dissenter agrees to accept that amount in full
satisfaction. The dissenter may decline the offer and demand payment under
subdivision 6. Failure to do so entitles the dissenter only to the amount
offered. If the dissenter makes demand, subdivisions 7 and 8 apply.

         (c) If the corporation fails to remit payment within 60 days of the
deposit of certificates or the imposition of transfer restrictions on
uncertificated shares, it shall return all deposited certificates and cancel all
transfer restrictions. However, the corporation may again give notice under
subdivision 4 and require deposit or restrict transfer at a later time.

         Subd. 6. Supplemental payment; demand. If a dissenter believes that the
amount remitted under subdivision 5 is less than the fair value of the shares
plus interest, the dissenter may give written notice to the corporation of the
dissenter's own estimate of the fair value of the shares, plus interest, within
30 days after the corporation mails the remittance under subdivision 5, and
demand payment of the difference. Otherwise, a dissenter is entitled only to the
amount remitted by the corporation.

         Subd. 7. Petition, determination. If the corporation receives a demand
under subdivision 6, it shall, within 60 days after receiving the demand, either
pay to the dissenter the amount demanded or agreed to by the dissenter after
discussion with the corporation or file in court a petition requesting that the
court determine the fair value of the shares, plus interest. The petition shall
be filed in the county in which the registered office of the corporation is
located, except that a surviving foreign corporation that receives a demand
relating to the shares of a constituent domestic corporation shall file the
petition in the county in this state in which the last registered office of the
constituent corporation was located. The petition shall name as parties all
dissenters who have demanded payment under subdivision 6 and who have not
reached agreement with the corporation. The corporation shall, after filing the
petition, serve all parties with a summons and copy of the petition under the
rules of civil procedure. Nonresidents of this state may be served by



                                       D-3



registered or certified mail or by publication as provided by law. Except as
otherwise provided, the rules of civil procedure apply to this proceeding. The
jurisdiction of the court is plenary and exclusive. The court may appoint
appraisers, with powers and authorities the court deems proper, to receive
evidence on and recommend the amount of the fair value of the shares. The court
shall determine whether the shareholder or shareholders in question have fully
complied with the requirements of this section, and shall determine the fair
value of the shares, taking into account any and all factors the court finds
relevant, computed by any method or combination of methods that the court, in
its discretion, sees fit to use, whether or not used by the corporation or by a
dissenter. The fair value of the shares as determined by the court is binding on
all shareholders, wherever located. A dissenter is entitled to judgment in cash
for the amount by which the fair value of the shares as determined by the court,
plus interest, exceeds the amount, if any, remitted under subdivision 5, but
shall not be liable to the corporation for the amount, if any, by which the
amount, if any, remitted to the dissenter under subdivision 5 exceeds the fair
value of the shares as determined by the court, plus interest.

         Subd. 8. Cost; fees, expenses. (a) The court shall determine the costs
and expenses of a proceeding under subdivision 7, including the reasonable
expenses and compensation of any appraisers appointed by the court, and shall
assess those costs and expenses against the corporation, except that the court
may assess part or all of those costs and expenses against a dissenter whose
action in demanding payment under subdivision 6 is found to be arbitrary,
vexatious, or not in good faith.

         (b) If the court finds that the corporation has failed to comply
substantially with this section, the court may assess all fees and expenses of
any experts or attorneys as the court deems equitable. These fees and expenses
may also be assessed against a person who has acted arbitrarily, vexatiously, or
not in good faith in bringing the proceeding, and may be awarded to a party
injured by those actions.

         (c) The court may award, in its discretion, fees and expenses to an
attorney for the dissenters out of the amount awarded to the dissenters, if any.
